Description

Technical Field

[0001] This utility model relates to the field of clumping removal technology, and in particular to a clumping removal device for the tail of a bucket elevator. Background Technology

[0002] In cement production, powdery materials such as fly ash and lime powder need to be transported between different equipment and storage areas. Bucket elevators can effectively prevent dust from flying, ensuring material conveying efficiency and environmental cleanliness. However, these powdery materials are affected by seasonality and have high humidity. During the operation of the bucket elevator, moisture will accumulate locally due to compression and friction. When the production operation time is long, it will accumulate in the area not covered by the bucket at the tail end of the bucket elevator, and the material is more likely to stick together and clump. Currently, air cannons are usually used to clean these clumps. The strong airflow of compressed gas suddenly sprayed by the air cannon breaks up the clumps. However, most existing air cannons are fixed single nozzles with limited spray angle and coverage area. For example, the output nozzle of the air cannon is located on one side of the bucket elevator, while the area in the middle of the bucket elevator and the other side receives less airflow intensity due to the greater distance from the output nozzle. Therefore, the cleaning effect of clumps in the middle area of ​​the bucket elevator and the area far from the output end of the air cannon is not good.

[0003] Based on the above situation, it is necessary to design a bucket elevator tail blockage cleaning device to solve the above problems. Utility Model Content

[0004] This invention provides a device for cleaning up clumps at the tail of a bucket elevator to solve the problems existing in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A bucket elevator tail agglomeration cleaning device includes a movable cleaning component and a telescopic drive component. The cleaning component includes an air cannon and a gas output unit connected to the air cannon output. The gas output unit is used to spray high-pressure gas to break up the agglomerated material at the bottom of the bucket elevator. The telescopic drive component is connected to the cleaning component and is used to drive the cleaning component to move along the bottom of the bucket elevator. The telescopic movement of the telescopic drive component can change the position of the cleaning component at the bottom of the bucket elevator, so that the gas output unit can perform air jet cleaning operations at different positions at the bottom of the bucket elevator, thereby achieving comprehensive cleaning of the bottom of the bucket elevator.

[0007] Preferably, the gas output unit includes a retractable gas supply main pipe connected to the output end of the air cannon and a jet pipe connected to the output end of the gas supply main pipe, wherein a plurality of jet nozzles are provided at equal intervals on the jet pipe.

[0008] Preferably, one side of the bucket elevator is provided with an installation compartment that communicates with the bottom of the bucket elevator, and a baffle is connected to the jet pipe. When the cleaning component is located in the installation compartment, the baffle is used to seal the installation compartment.

[0009] Preferably, the bottom of the baffle is provided with a cutting edge for cutting agglomerated materials.

[0010] Preferably, the jet pipe is provided with connectors at both ends, and the connectors are slidably connected to the inner wall of the bucket elevator and the installation chamber.

[0011] Preferably, the expandable structure of the gas transmission main can be a multi-layer sealed corrugated structure or a nested expandable structure.

[0012] The beneficial effects of this utility model are: by using the telescopic drive component to move the jet pipe and jet nozzle along the bottom of the bucket elevator, the airflow can cover all corners of the bottom of the bucket elevator, effectively solving the problem of uneven cleaning caused by the decrease in airflow intensity with distance in traditional fixed nozzles. In addition, during the movement, the jet nozzle can clean at different positions with a relatively stable airflow intensity, avoiding uneven cleaning caused by position differences, and achieving a comprehensive and thorough cleaning.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] Reference Figures 1-4 As shown, a bucket elevator tail agglomeration cleaning device includes a movable cleaning component and a telescopic drive component 4 connected to the cleaning component for moving it along the bottom of the bucket elevator 3. The telescopic drive component 4 can be an electric telescopic rod or similar device. The cleaning component includes an air cannon 1 and a gas output unit 2 connected to the output of the air cannon 1. The gas output unit 2 is used to spray high-pressure gas to break up the agglomerated material at the bottom of the bucket elevator 3. The gas output unit 2 includes a telescopic air supply main pipe 21 connected to the output end of the air cannon 1 and a jet pipe 22 connected to the output end of the air supply main pipe 21. The jet pipe 22 has multiple jet nozzles 23 evenly spaced on it. When the bucket elevator 3 stops conveying materials, the high-pressure gas released by the air cannon 1 is ejected from the nozzle at high speed in a very short time, forming a powerful impact force. The impact force can directly act on the surface of the agglomerated material to break it up and clean it. When the telescopic drive component 4 extends and retracts, it can change the position of the cleaning component at the bottom of the bucket elevator 3, so that the gas output unit 2 can perform jet cleaning operations at different positions at the bottom of the bucket elevator 3. This effectively solves the problem of cleaning dead zones caused by the decrease in airflow intensity with distance in traditional fixed air nozzles. This ensures that the agglomerated material at the bottom of the bucket elevator 3 can be subjected to a sufficiently strong airflow impact, achieving comprehensive and thorough cleaning, no matter where it is.

[0021] Reference Figure 4 As shown, the telescopic structure of the gas main pipe 21 can be a multi-layer sealed corrugated structure or a nested telescopic structure. When the telescopic drive 4 drives the jet pipe 22 to move at the bottom of the bucket elevator 3, the telescopic gas main pipe 21 can adjust the length while avoiding gas leakage and adapt to the movement of the jet pipe 22. The multi-layer sealed corrugated structure or the nested telescopic structure are existing technologies, which should be known to those skilled in the art, and will not be described in detail here.

[0022] The bucket elevator 3 has an installation chamber 5 connected to the bottom of the bucket elevator 3 on one side. A baffle 6 is connected to the air jet pipe 22. When the cleaning component is inside the installation chamber 5, the baffle 6 is used to block the installation chamber 5 to prevent material from entering the interior of the installation chamber 5 when the bucket elevator 3 is lifting and conveying materials. When the telescopic drive 4 drives the cleaning component to clean the clumps of material, the baffle 6 moves into the interior of the bucket elevator 3. The bottom of the baffle 6 is provided with a blade 61 for cutting the clumps of material. The blade 61 can be in a cone-shaped state or a serrated state. When the baffle 6 moves inside the bucket elevator 3, the blade 61 can scrape off the clumps of material. When the air cannon 1 does not completely clean some stubborn clumps of material, the blade 61 can scrape them off when the baffle 6 is reset. In addition, the air cannon 1 can be turned off during cleaning, and the reciprocating motion of the baffle 6 driven by the telescopic drive 4 can achieve single material scraping and cleaning by the blade 61.

[0023] Reference Figure 3 As shown, further, connectors 7 are provided at both ends of the jet pipe 22. The telescopic drive 4 is connected between the connector 7 and the installation chamber 5. The connector 7 is slidably connected to the bucket elevator 3 and the inner wall of the installation chamber 5. When the telescopic drive 4 drives the jet pipe 22 to move, the connector 7 guides and limits the movement of the jet pipe 22, making the movement trajectory of the jet pipe 22 more stable and avoiding the impact force of the jet nozzle 23 when spraying airflow, which affects the movement stability of the jet pipe 22.
