In fact, this depends on the selected file rack manufacturer. Whether a good file rack manufacturer chooses to tile or slot, it will not affect the floor. In response to these problems, the compact rack manufacturer will give you a detailed explanation of the laying methods of the compact track, and whether the ground will be damaged when laying the track.

Laying method of compact rack

Mobile archive shelving

The laying methods of common file rack tracks are basically divided into two types: above-ground rails and underground rails:

1. Ground track

The above-ground track is not only easy to install, but also less destructive to the ground. The operation method is to lay the track directly on the ground and fix it with the ground with bolts.

2. Underground track

The underground track needs to be cut through the ground for re-grooving, or it needs to be pre-embedded. The installation operation is to lay the track of the dense frame below the ground. The laying method needs to be selected according to the specific conditions of the archives.

What are the advantages of plant grow racks over agricultural systems?

The plant grow rack is a high-efficiency agricultural system that realizes the annual continuous production of crops through high-precision environmental control in the facility. In a limited space, scientists use computers to precisely control the temperature, humidity, light, carbon dioxide concentration, nutrient solution and other environmental conditions required for plant growth and development to obtain high-quality, high-yield agricultural products. So what are the advantages of growing racks over traditional farming systems?

Intensive

That is to say, intensive production reflects the overall comprehensive benefits of resources, technology and labor, improves the material output per unit area, and alleviates the contradiction between food supply and demand. The plant growth rack adopts a three-dimensional planting method, compresses the area of ​​the equipment to expand the planting area, and effectively utilizes the indoor space and equipment space through reasonable hole design.

Grow racks

Efficient

That is to fully tap the potential of agricultural and industrial by-products, light, water and other resources, ease the contradiction between man and land, ease the conflict between grain and cash crops, vegetables, fruits, etc. for land, improve the utilization rate of resources, and improve the utilization rate of artificial auxiliary functions. usage efficiency. Take lettuce as an example, it takes about 40 days to mature under natural conditions, but only about 20 days in a plant factory. At the same time, because of multi-layer cultivation, on the same area of ​​land, the output of plant factories can reach dozens or even hundreds of times that of conventional cultivation.

PRODUCTION PROCESS AND PRECAUTIONS OF CALCIUM HYDROXIDE EQUIPMENT

Calcium hydroxide equipment, also known as calcium hydroxide production line, is mainly used for the production of calcium hydroxide. With the increasing application of calcium hydroxide in industrial production, calcium hydroxide equipment has also been upgraded many times. There has been a qualitative change from performance to product. For the production process of calcium hydroxide equipment, everyone is not very clear, so in response to this problem, calcium hydroxide equipment manufacturers give you the following detailed introduction.

THE PRODUCTION PROCESS OF CALCIUM HYDROXIDE EQUIPMENT

GFEX Case

1. Pulverized calcium oxide

During production, the raw material calcium oxide (CaO) needs to be added into the silo, and then added to the jaw crusher evenly through the vibrating feeder, and crushed to a particle size of about 40 mm. The dust generated during the crushing process will be introduced into the pulse dust collector outside the workshop through the dust cover of the crusher through the induced draft fan. It is recommended to clean the calcium oxide powder in the dust collector once a week.

2. Digestive reaction

The crushed calcium oxide is lifted to the digester by the bucket elevator for digestion reaction. Calcium oxide needs to enter the first-level digester for preliminary digestion. When the primary digestion is completed, it will enter the second-level digestion or the third-level digester, so that the calcium oxide can be fully digested and decomposed to generate qualified calcium hydroxide primary products. Can reach 98%.

The feed port of the digester is designed with a screw feed propeller to facilitate material transportation. Most of them adopt a double-shaft stirring structure, which has the functions of stirring, crushing agglomeration and self-cleaning. Its unique paddle and stirring formula can make calcium oxide and water fully and evenly mixed together, the reaction is more complete, and it plays a role in the agglomeration generated during the reaction.

What should I do if the vibrating screen discharges?

In daily production, during the use of the vibrating screen, a relatively obvious material conveying is suddenly not smooth, followed by the problem that the discharge is biased in a certain direction. To solve this problem, we must first find out the reason for the deviation of the material, and then find out how to solve the problem of the deviation of the vibrating screen. In response to the above problems, the vibrating screen manufacturer gave us a detailed introduction.

The reason for the deviation of the vibrating screen

High frequency dehydration vibrating screen

1. The vibrating screen has a long working time

The vibrating screen has a large workload and a long working life. For a large linear vibrating screen, due to its heavy weight, if coupled with repeated vibration and strong inertia for many years, some parts of the body will be loose, which will lead to vibration. The angle of the motor changes, so the phenomenon of discharge deviation occurs.

2. Uneven feeding

If the vibrating screen is feeding more or less, it is easy to cause unstable screening accuracy, and because of the more or less material, the force deviation of the material is large, and there is a problem that the discharge is biased to one side.

3. Exciter installation problem

The transportation and screening of materials by the vibrating screen is pushed by the vibration exciter to the material with a fixed magnitude of excitation force in a designed fixed direction. Therefore, if the material conveying is not good, it can basically be judged as a vibration exciter. There is a problem with the installation angle. Under normal circumstances, the manufacturer will perform precise installation, testing, and adjustment before the equipment leaves the factory to avoid the deviation of the excitation force direction, so this problem is generally not the cause of the new machine.

Introduction to the fluidization of powder particles

When the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/s for cement), the friction between the gas and the powder is equal to the weight of the powder, and the powder no longer depends on the flow. The bed supports, at this point they can move freely and flow from high to low, keeping the upper plane of the powder layer horizontal, similar to liquid properties.

If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called the fluidization of the powder. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to make the compressed air form a fine and uniform airflow into the powder layer to fluidize the powder.

Why do concrete mixer trucks turn while walking?

Concrete mixer truck is a special truck used to transport concrete for construction. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete. The power is transmitted to the hydraulic pump, the hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe, and the hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the deceleration and torque increase of the reducer. The handle angle can realize the forward and reverse rotation of the mixing tank and the size of the rotating speed, so as to realize the operations of concrete charging, stirring, stirring and discharging. The concrete mixer truck will always keep the mixing drum rotating during transportation, so do you know why it needs to rotate while walking?

1. Improve the efficiency of use

concrete mixer truck

Concrete mixer trucks involve transportation time, and it takes a certain amount of time for concrete to travel from the manufacturer to the construction site. If the concrete mixer truck walks and turns on the road, the mixing time of the materials can be combined with the time of transportation on the road, which improves the utilization rate of time and improves the work efficiency. Especially in hot summer, the solidification of concrete can be prevented by continuous stirring. After all, for manufacturers and builders, the value of a truck of concrete is still great.
