Description

The invention relates to the field of construction, in particular to automated railroad cement warehouses and a direct cement application unit, and can be used to quickly unload cement in a storage tank or directly to a cement application unit.

A well-known automated railroad cement storage warehouse is located, in which four cement storage tanks are located, pneumatic conveying devices for moving cement and a receiving device into which discharge is directly carried out. The warehouse also includes a precipitating hopper and a cleaning filter.

In addition, from advertising brochures and technical projects, the designs of automated railroad cement storage warehouses and the method of their operation are known, including cement storage tanks, pneumatic conveying devices, and a receiving device. [one]

The disadvantage of these cement storage warehouses is that they unload cement directly through a receiving device located in the basement below the level of the railroad track. Due to the fact that most of the incoming cement does not come in cement wagons, but by road, when unloading cement, a large amount of electricity is consumed in the receiving device, due to the fact that their productivity is much higher than the amount of cement unloaded, which leads to the fact that the receiving the device is idling.

There is also known a method of operation of an automated railroad cement storage warehouse, which includes a receiving device located in the basement below the level of the railway bed, a pneumatic piping system for moving cement, a silo gallery, a silo-precipitator, silo cans and a unit for the direct use of cement, in which cement is first stored in storage tanks, and then issued for direct use.

A disadvantage of the known device is that with the direct use of cement in the technological process, a large amount of time is spent when unloading cement first in a storage tank, and then pumping it from silo cans to a unit where it is used directly.

To eliminate the above disadvantages, it is necessary to exclude the use of receiving devices when unloading cement. This will reduce energy consumption in automated railroad cement storage warehouses and reduce time costs when pumping cement directly to its application site.

The problem is solved in that in a well-known automated railroad cement storage warehouse, which includes a receiving device for supplying cement from cars to it, located in the basement below the level of the railway bed, silo cans and a pneumatic pipe for moving cement from the receiving device to the precipitating bunker located in the silo gallery, and communicated by means of an aeroshaft with silo banks on the pneumatic pipe to move cement from the receiving device to the hopper -osaditelyu installed pipe for connection with a hose cement truck, the warehouse and provided with a plug, mounted on the outlet of the tubing or piping from the receiving device when unloading the cement.

Another difference is that to the pneumatic pipe going from the storage warehouse to the direct cement application unit, another pipe is installed for connection to the cement truck. Through this pipe, cement is directly unloaded to its application site.

The introduction of the pipe into the pneumatic pipe, going from the receiving device to the bunker-precipitator, can reduce energy costs during unloading of cement, which characterizes the inventive step of the technical solution. And also the introduction of the pipe into the pneumatic pipe, going from the storage warehouse to the warehouse of direct use, allows to reduce the time spent on transportation of cement from the storage warehouse to the warehouse of direct use, which also characterizes the inventive step of the technical solution.

An additional search in the patent literature showed that there is no device with similar features, which confirms the novelty of the solution.

The invention is schematically illustrated by the drawing.

The drawing in schematic form shows a schematic diagram of an automated railroad warehouse for cement storage.

The automated railroad cement storage warehouse consists of a receiving device 1, a pneumatic piping system 2, going from the receiving device to the silo gallery 3, in which a hopper-precipitator 4 is installed and an air duct 5 is located. Air is pumped through pipelines using three compressors located in compressor 6. Also, an automated railroad cement storage warehouse contains silo cans 7, a pneumatic piping system 8, pipes 9, 10. Directly next to the cement storage warehouse is located direct application of the cement 11.

Automated rail warehouse cement storage works as follows.

If there are no cars with cement, a cement truck is sent to the cement storage instead. With a hose, the cement truck joins the pipe 9 coming from the pneumatic pipe 2. Three compressors are switched on in compressor 6, which create air pressure. A plug is installed at the inlet of the pneumatic pipe 2 to the receiving device 1, which eliminates the loss of air from the pneumatic pipe 2 when pumping cement from the cement truck to the silo gallery 3. In the cement truck, a valve opens and the cement is picked up by air through the pneumatic pipe 2 and sent to the silo gallery 3, where cement after deposition in the precipitating hopper 4 with a chute 5 is loaded into the corresponding silo jar 7. After deposition in the silo jar 7, cement, if necessary, directs through the pneumatic pipe 8 to the site for direct application of cement 11. This scheme can also be applied when there is no need to store cement. With the direct use of cement, it is immediately most expedient that the cement is sent, bypassing the storage warehouse, directly to the direct application unit. To do this, a pipe 10 is connected to the pneumatic pipe 8 from the cement warehouse to the direct cement application unit. In this case, the cement truck is connected directly to pipe 10. Air is also pumped by three compressors, and cement from the cement truck is sent to the direct application unit. At the same time, the time it takes for cement to enter its application site is significantly saved.

Testing the proposed automated railroad warehouse for storing cement and the method of its operation made it possible to significantly reduce the time required for unloading and transporting cement from the warehouse to the direct application unit, which confirms the industrial applicability of the claimed technical solution. In addition, a significant technical effect is that when unloading cement there is no need to use a receiving device, which, in turn, significantly reduces energy costs, which is not found in any of the known analogues and prototypes.
