Description

Technical Field

[0001] This utility model relates to the field of mining processing machinery technology, specifically a silo cleaning device. Background Technology

[0002] The powder silo suffers from material caking and impede flow. Material adheres to the silo walls, reducing the effective volume to the design capacity and causing blockages that disrupt silo discharge, interrupting downstream ore feeding and impacting production efficiency. To maintain process continuity, manual churning is required to force discharge, which poses a safety hazard. Current technologies typically use compressed air to clean the material adhering to the silo. However, these air-cleaning devices often have uneven air outlets, making them prone to material adhesion. This adhesion, combined with moisture in the air, further exacerbates the problem. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-point vibration device for iron-boron-magnesium powder silos, including an air compressor. The compressor outputs compressed air to an air storage tank, which is then transported to an air cannon through an air pipe. The air cannon includes a base plate and side plates. The base plate is fixed to the outside of the silo. The head of the vibrating tube of the air cannon is inserted into the side wall of the silo and flush with the inner wall of the silo. The middle part of the vibrating tube is fixed to a retaining ring, and the tail part of the vibrating tube is connected to the air pipe. The retaining ring abuts against a collar at one end of a swing rod fitted on the vibrating tube. The swing rod is axially connected to a support shaft. The other end of the swing rod is fixed to one end of a tension spring, and the other end of the tension spring is fixed to a tension spring support plate. The swing rod near the tension spring abuts against the vibration device. The outside of the vibrating tube is slidably connected to a sliding sleeve, which is fixed to the base plate.

[0004] The air cannons are multiple in number and are evenly arranged on the circumference of the side of the hopper and above the discharge port.

[0005] The vibration device includes a cam, which is connected to the output shaft of a pneumatic motor and abuts against a rocker arm.

[0006] The vibration device is a cylinder, and the piston end of the cylinder abuts against the rocker arm.

[0007] The vibration device is an electromagnetic hammer, and the hammerhead of the electromagnetic hammer strikes the pendulum.

[0008] The advantages of this invention are: when the air cannon is in use, it can combine the axial impact of the vibrating tube to mechanically impact the material adhering to the air outlet, causing the material to move outward and then fall due to gravity, thus ensuring the cleaning of the material and overcoming the defects of the prior art.

[0014] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the figures, the present invention includes an air compressor 15, which outputs compressed air into an air storage tank 16, and then delivers it to an air cannon 18 through an air pipe 17. The air cannon includes a base plate 8 and a side plate 7. The base plate is fixed to the outside of the hopper 10. The head of the vibrating tube 1 of the air cannon is inserted into the side wall of the hopper and is flush with the inner wall of the hopper. The middle part of the vibrating tube is fixed to a retaining ring 2, which can be welded to the vibrating tube. The tail of the vibrating tube is connected to the air pipe. The retaining ring abuts against a collar 31 at one end of a swing rod 3 fitted on the vibrating tube. The swing rod is axially connected to a support shaft 4. The other end of the swing rod is fixed to one end of a tension spring 6, and the other end of the tension spring is fixed to a tension spring support plate 12. The swing rod near the tension spring abuts against a vibration device 5. To ensure accurate positioning of the vibrating tube, the outer side of the vibrating tube is slidably connected to a sliding sleeve 9, which is fixed to the base plate. The inner diameter of the collar 31 is larger than the outer diameter of the vibrating tube 1.

[0015] Multiple air cannons 18 are evenly arranged on the side circumference of the hopper and above the discharge port 14.

[0016] A vibration device includes a cam 5, which is connected to the output shaft of a pneumatic motor 11 and abuts against a rocker arm. The pneumatic motor drives the cam to rotate. In this embodiment, the cam rotates clockwise. After the cam lifts the rocker arm, the rocker arm is suddenly released as the cam rotates. Under the action of the tension spring, the rocker arm rotates clockwise around the support shaft 4, thereby pushing the vibrating tube forward and colliding with the material 13 adhered to the inner wall of the hopper.

[0017] like Figure 5 As shown, another type of vibration device is a cylinder 51, the piston end of which abuts against the rocker arm, and the cylinder is fixed on the spring support plate 12.

[0018] The vibration device can also be an electromagnetic hammer, in which the hammerhead strikes a pendulum. The principle of an electromagnetic hammer is to use electromagnetic attraction to the hammerhead to generate a hammering action. Commercially available electromagnetic hammers can be used.

[0019] In addition, an impact hammer can also be used as the vibration device; any device capable of generating an impact action is acceptable.

[0020] In order to generate a larger impact force, the support shaft 4 can be positioned close to the end of the collar 31, which will generate a lever arm and bring a larger impact force with a smaller vibration force.

[0021] Air cannons are available in different specifications: one with a capacity of 500L, installed at a designated location on the silo wall; and another with a capacity of 300L, installed above the discharge port. The air cannon body has a storage pressure of 0.4–0.8 MPa, a pressure bearing capacity of 1.1 MPa, and a safety valve seat on the tank.

[0022] The air cannon's outlet vibratory tube uses a DN100 seamless steel pipe, with a length between 400mm and 500mm, depending on the thickness of the powder silo. The working pressure is 0.4-0.8 MPa, and the air source requires a 4m³ air tank. 3 / 0.8MPa, screw air compressor 4m 3 / 0.8MPa / 15KW.
