Description

Technical Field

[0001] The present application relates to the technical field of silo components, and more specifically, to a silo blockage clearing system with strong temperature adaptability. Background Art

[0002] In existing technologies, material flow within silos relies primarily on gravity and silo height differences. However, factors such as material properties and silo structure can affect the flow. For example, high levels of powder and moisture in the material can easily cause silo blockages, such as silo clogging. Severe silo blockage can disrupt the entire process and even cause production halts.

[0003] Therefore, in the prior art, a related clearing system (device) is designed to solve the silo blockage problem:

[0004] For example, the utility model patent application with application number 201811363797.6 discloses a silo blockage clearing device and its use method, wherein the silo blockage clearing device includes a silo, an air source system, a control air flow pipeline system, a working air flow pipeline system, an injection system and an electronic control system, the control air flow pipeline system and the working air flow pipeline system are both connected to the air source system, the control air flow pipeline system is connected to the electronic control system, the electronic control system is connected to the injection system, the working air flow pipeline system is connected to the injection system, and the injection system is connected to the silo, and the gas passes from the air source system through the working air flow pipeline system to the injection system, and then is injected into the silo through the injection system to blow down the blocked materials accumulated in the silo. This utility model patent application adopts pneumatic blockage clearing technology, relying on the instantaneous explosive force of compressed air to reduce the internal friction between materials and the external friction between materials and the inner wall of the conical steel plate silo, effectively solving the problem of material blockage in the conical steel plate silo, especially the wall sticking and shelf material blockage caused by high-water-content fine powder.

[0005] For example, the utility model patent application with application number 202010147222.1 discloses a clearing and flow-aiding device and method of use for preventing and controlling blockages in rectangular flat-bottomed deep silos. The clearing and flow-aiding device is composed of an air source system, an in-silo flow-aiding injection system, an out-of-silo main pipeline system, a control pipeline system, and an electronic control system. The in-silo flow-aiding injection system is composed of 3 to 4 layers of in-silo flow-aiding air ducts and nozzles installed thereon. The in-silo flow-aiding air ducts on the same layer are arranged in two L-shaped splits. The nozzles are composed of a central injection pipe of the silo set at the upper and lower parts and a downward injection pipe parallel to the natural stacking slope. The method of use has both manual control and automatic control modes. This utility model patent application has the characteristics of low construction difficulty, low modification cost, high work efficiency, and convenient operation. It can eliminate the safety hazards caused by manual clearing in the past, ensure the operation rate of subsequent processes and equipment, and has significant economic and safety benefits. It can be widely used in feeding in mining, metallurgy, power generation, coal, and chemical related industries.

[0006] For another example, the utility model patent application with application number 202010147188.8 discloses a conical steel cylinder feeding silo with intelligent anti-blocking and clearing functions, which is composed of a conical steel cylinder silo and an intelligent clearing device. The intelligent clearing device and the intelligent clearing and flow-aiding device are composed of an air source system, a control air circuit system, a flow-aiding air circuit system, an injection mechanism and an electronic control system. The injection mechanism includes a nozzle, a pneumatic butterfly valve, and a working air circuit annular branch pipe. The working air circuit annular branch pipes are arranged in layers from top to bottom on the outside of the conical steel cylinder silo. The nozzle's injection pipe includes a central injection pipe in the silo and an oblique downward injection pipe parallel to the inner wall of the silo. This utility model patent application has the characteristics of high clearing efficiency, stable working performance, and easy maintenance. It completely eliminates the safety hazards caused by manual clearing. At the same time, it can reduce the startup and idling time of equipment such as crushing and ball milling, save production costs, and have obvious economic benefits.

[0007] For example, the utility model patent application number 202320231662.4 discloses a silo blockage removal device, which specifically includes a silo body, a discharge pipe, a plurality of annular pipes, a plurality of nozzles, a flow-aiding pipe, a control line, an air storage tank, and a plurality of valves. This utility model arranges a high-pressure air nozzle on the inner wall of the steel silo structure of the silo body, and sprays a high-pressure airflow into the silo body close to the silo wall. The spray angle can be adjusted according to the structure of the silo body. The high-pressure gas creates a small gap between the material and the silo wall, thereby reducing the frictional resistance between the material and the silo wall, eliminating the phenomenon of material wall formation and blockage, ensuring the continuous operation of the main equipment, reducing power consumption, ensuring the smooth production process and stable quality, while reducing the labor intensity of workers and ensuring safe production.

[0008] The related technologies mentioned in the above-mentioned prior art use pneumatic clearing. However, in a low temperature environment caused by cold weather and other conditions, the raw coal in the coal bunker has a moisture content of 9%-25%, which can easily cause the raw coal in the coal bunker to freeze, making it impossible for the coal mine to unload normally. The working pipeline of the pneumatic clearing is also prone to ice and blockage, which greatly affects the normal operation of the clearing system. Moreover, the frozen raw coal in the silo can usually only be relieved by destroying the silo wall and manually breaking the blockage, which poses a great safety hazard and has low breaking efficiency.
