Description

Technical Field

[0001] The utility model relates to the application field of cement production technology, in particular to a cement silo blocking clearing and preventing device. Background Art

[0002] With the continuous improvement of cement production technology, the cement output of cement production lines has continued to increase, and the cement storage link has become increasingly important. At present, the main way to store cement is to store and homogenize it in silos. The smoothness of cement silo discharge is related to the shape, angle, material, outlet cross-section, and the material's own characteristics, water content and other factors. Therefore, blockages often occur, seriously affecting the production process. Common forms of blockage in cement silos include arches, rat holes and wall hangings. At present, the mainstream solution at home and abroad is to solve it through manual or partial machine clearing, but the problems associated with clearing have gradually emerged with the country's requirements for safe production and green development. The main manifestations are that online clearing cannot be achieved, the cost of clearing is high and it causes damage to the silo. In response to the above problems, the inventor designed an anti-blocking and clearing device that can be used in the process of silo discharge, so as to reduce the risk of production interruption and ensure the continuous and smooth discharge of materials. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a cement silo clearing and anti-blocking device. When the sensor senses the silo blockage signal, the controller controls the solenoid valve to open first, and the high-pressure gas stored in the air cannon is sprayed into the silo. The shock wave overcomes the arching or wall sticking caused by the viscosity of the material, which not only clears the arch layer around the air cannon, but also destroys the overall arch stress; then the high-frequency vibration motor starts to run, and the elastic buffer vibration part drives the vibrating liner to vibrate at high frequency, forcing the arch stress in the silo to be completely dispersed and broken, and the material slides down naturally according to its own gravity, thereby achieving the arch breaking effect.

[0004] The technical solution of the utility model is: a cement silo clearing and anti-blocking device, which includes

[0005] A silo, wherein a plurality of vibration mechanisms are arranged in an array distributed on the periphery of the silo, and the vibration mechanisms include a clearing component and a vibration component;

[0006] The blockage clearing assembly includes an air cannon and a first pipe, one end of the first pipe is connected to the air cannon, and the other end of the first pipe is connected to the side wall of the silo;

[0007] The vibration assembly includes a vibration motor and a vibration lining plate, and the vibration motor drives the vibration lining plate to vibrate through a buffer vibration member.

[0008] Preferably, the clearing assembly also includes a mounting liner and a mounting plate, wherein the mounting liner is arranged on the outer periphery of the silo by bolts, and the mounting plate is provided with a first mounting hole, the mounting plate is vertically arranged on the outside of the mounting liner, and the air cannon is arranged on the upper part of the mounting plate through a mounting bracket.

[0009] Preferably, a solenoid valve for controlling the switch of the air cannon opening end is further provided between the air cannon and the first pipeline, and a connecting flange is provided on the side of the air cannon away from the solenoid valve.

[0010] Preferably, the silo is provided with a second mounting hole, one end of the buffer vibration member is connected to the vibration lining after passing through the first mounting hole and the second mounting hole, and the other end of the buffer vibration member is connected to the output end of the vibration motor, and the vibration motor is arranged at the lower part of the mounting plate.

[0011] Preferably, a plurality of striped protrusions are arranged in parallel on the surface of the vibration lining.

[0012] Preferably, the vibration motor is provided with a high-frequency vibration motor.

[0013] Preferably, the buffer vibration member is configured as an elastic buffer vibration member.

[0014] The beneficial technical effects of the utility model are:

[0015] The clearing component and the vibration component are combined into one clearing device to achieve two-step clearing. When there is blockage, the air cannon first emits high-pressure gas to destroy the sticking wall, and then the high-frequency vibration motor drives the vibrating liner to completely destroy the arch stress to achieve clearing. The device has a large clearing area, high efficiency, and clears the blockage thoroughly. It can complete the clearing without affecting other processes of the cement production line, reduce the risk of production interruption, and ensure continuous and smooth material discharge. No manual on-site operation is required. When the silo is blocked, it is only necessary to open the clearing and anti-blocking device to complete the clearing, which greatly reduces labor costs. The vibrating liner is equipped with a silo wall protection plate, which can effectively protect the silo wall and extend the service life of the silo.
