Technical Field

[0001] The utility model relates to the technical field of cement production and storage equipment, in particular to a cement silo bottom clearing device. Background Art

[0002] A cement silo, also known as a cement storage depot or cement silo, is a large container used to store cement or other similar dry powder materials. In the construction industry, cement silos are typically used to store bulk cement for use on construction sites. The bottom discharge device of a cement silo in a cement plant consists solely of an arc valve, a flow valve, and an aeration box. Compressed air in the aeration box pushes the cement through the arc valve and flow valve into various cement dispersal channels.

[0003] However, the above-mentioned publicly available solutions have the following shortcomings: if the crust on the internal wall of the cement warehouse falls off or the cement becomes damp and lumps into the buffer tank, the arc valve and the flow valve will be stuck and cannot be opened and closed normally, resulting in the valve being unable to open and the cement being unable to be shipped, or the valve being unable to be closed in time causing material rushing, which creates environmental risks. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that the crust on the inner wall of the cement silo falls off or the cement becomes damp and lumps into the buffer box, which will cause the arc valve and the flow valve to be stuck and unable to open and close normally, resulting in the valve being unable to open and the cement being unable to be shipped, or the valve being unable to be closed in time causing material rushing, which creates environmental risks. The utility model provides a cement silo bottom clearing device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model discloses a cement silo bottom clearing device, comprising a cement silo body; a lower end outlet of the cement silo body is detachably fixedly connected to an external square tube; a buffer box is connected and fixedly connected to the external square tube; a filter plate is inserted into the buffer box; a vibration transmission plate is sleeved on the filter plate and the buffer box; a vibration motor is fixedly connected to the vibration transmission plate; a crushing pipe is connected and fixedly connected to the side surface of the buffer box corresponding to the filter plate.

[0007] Furthermore, a switch gate is inserted into a groove in the crushing pipe; a gate sleeve is sleeved on the switch gate; the gate sleeve is sleeved on the crushing pipe; and an arc valve is connected and fixed to the lower end of the crushing pipe.

[0008] Furthermore, the lower end of the crushing pipe is connected to a crushing box; a hydraulic cylinder is symmetrically fixed to the crushing box; the movable end of the hydraulic cylinder is fixed to mutually nested extrusion layers; the extrusion layers are provided with equidistant crushing holes with equal diameters from top to bottom.

[0009] Furthermore, a support frame is fixedly connected between the crushing pipe and the buffer box; and the lower end of the buffer box is connected and fixedly connected to a collecting cover.

[0010] Furthermore, the filter plate is fixedly connected in a tilted manner in the buffer box; and vertically upward filter holes are uniformly distributed on the filter plate.

[0011] Furthermore, a conveyor belt is provided at the lower end of the collecting cover and the crushing pipe.

[0012] The utility model provides a cement silo bottom clearing device, which has the following beneficial effects:

[0013] 1. The utility model opens the lower end of the cement silo, allowing the cement to descend and pass through the filter plate for filtration. When the vibration motor is energized, the vibration transmission plate and the filter plate are driven to vibrate, and the unagglomerated cement powder descends through the filter plate, and the agglomerated cement enters the crushing pipe for crushing under the shaking of the inclined surface of the filter plate. In this way, the function of automatically screening out agglomerated cement and crushing it is achieved without affecting the delivery of cement. At the same time, the workload of the staff and the safety and environmental protection risks are greatly reduced, and no agglomerated cement is wasted. The problem of the existing cement silo requiring shutdown for separate cleaning of blockages and heavy workload is solved.

[0014] 2. The utility model controls the amount of agglomerated cement entering the crushing pipe by changing the position of the switch gate in the crushing pipe and the gate casing, so that crushing can be carried out continuously at the highest crushing efficiency, and the discharge speed of cement powder can be controlled by the arc valve.

[0025] A switch gate 10 is slotted in the crushing pipe 8; a gate sleeve 11 is sleeved on the switch gate 10; the gate sleeve 11 is sleeved on the crushing pipe 8; the lower end of the crushing pipe 8 is connected and fixedly connected with an arc valve 13; during operation, the amount of agglomerated cement entering the crushing pipe 8 is controlled by changing the position of the switch gate 10 in the crushing pipe 8 and the gate sleeve 11, so that crushing can be carried out continuously at the highest crushing efficiency, and the speed of discharging cement powder can be controlled by the arc valve 13.

[0026] The lower end of the crushing pipe 8 is connected and fixedly connected to a crushing box 12; a hydraulic cylinder 14 is symmetrically fixedly connected to the crushing box 12; the movable end of the hydraulic cylinder 14 is fixedly connected to mutually nested extrusion layers 15; the extrusion layers 15 are provided with equidistant crushing holes 16 with equal diameters from top to bottom; when working, the two symmetrical hydraulic cylinders 14 drive the two mutually nested extrusion layers 15 to move, so that the agglomerated cement can be squeezed and crushed into a smaller volume, and then further crushed along the equidistant crushing holes 16, so as to be crushed to the equidistant crushing holes 16 with the smallest diameter, thereby achieving the crushing effect, and the dynamic crushing makes it possible to crush a large amount of agglomerated cement at the same time, solving the problem that the existing clearing device cannot crush a large amount of agglomerated cement at the same time.

[0027] A support frame 9 is fixedly connected between the crushing pipe 8 and the buffer box 3; the lower end of the buffer box 3 is connected and fixedly connected with a collecting cover 18; when working, the collecting cover 18 makes the cement falling in a large area become a small area, so that it can be collected in a centralized manner to reduce diffusion.

[0028] The filter plate 6 is fixedly connected to the buffer box 3 at an angle; vertically upward filter holes 7 are evenly distributed on the filter plate 6; during operation, the unagglomerated cement particles can pass through the filter plate 6 smoothly and quickly under the action of gravity through the vertically upward filter holes 7, thereby minimizing the discharge speed of the cement, thereby solving the problem of greatly reduced speed caused by the existing filtering of agglomerated cement.

[0029] A conveyor belt 17 is provided at the lower end of the collecting cover 18 and the crushing pipe 8. When in operation, the conveyor belt 17 can receive and transfer the un-agglomerated cement, and can also receive the crushed cement passing through the crushing pipe 8, so that the conveyor belt 17 can be used for transfer, so that the agglomerated cement will not block the cement storage body 1 and cause greater losses.

[0030] The present invention adopts the above-mentioned scheme, when in use, by opening the lower end of the cement storage body 1, the cement mixture is allowed to descend and pass through the filter plate 6 for filtration. When the vibration motor 5 is energized, the vibration transmission plate 4 and the filter plate 6 are driven to vibrate, and the unclumped cement powder passes through the filter plate 6 and descends. The agglomerated cement enters the crushing pipe 8 for crushing under the shaking of the inclined surface of the filter plate 6, thereby realizing the function of automatically screening out agglomerated cement and crushing without affecting the cement shipment, and at the same time greatly reducing the workload of the staff, and at the same time, no agglomerated cement is wasted, solving the problem that the existing cement storage needs to be shut down for separate cleaning of blockage and heavy workload; by changing the position of the switch gate 10 in the crushing pipe 8 and the gate casing 11, the amount of agglomerated cement entering the crushing pipe 8 is controlled, so that it can be crushed continuously at the highest crushing efficiency, and the speed of discharging cement powder can be controlled by the arc valve 13; two symmetrical hydraulic cylinders 14 drive two mutually nested extrusion layers 15 to The crushing process is carried out by the crushing machine 11, and the crushing effect is achieved by the crushing machine 12. The crushing machine 11 can crush a large amount of cement lumps at the same time, solving the problem that the existing cleaning device cannot crush a large amount of cement lumps at the same time. The collecting cover 18 makes the cement that falls in a large area become a small area, so that it can be collected in a centralized manner to reduce diffusion. The vertically upward filtering holes 7 allow the unagglomerated cement particles to pass through the filter plate 6 smoothly and quickly under the action of gravity, so that the discharge speed of the cement is not reduced much, solving the problem that the existing filtering of agglomerated cement greatly reduces the speed. The unagglomerated cement can be received and transferred by the conveyor belt 17, and the crushed cement that passes through the crushing pipe 8 can also be received, so that it can be transferred by a conveyor belt 17, so that the agglomerated cement will not block the cement storage body 1 and cause greater losses.
