Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, specifically to a dust removal device for long-distance dust removal air inlet pipes. Background Technology

[0002] In the mineral processing industry, a large amount of dust is generated during ore crushing. This dust enters the dust collector fan through the inlet duct, where it settles due to the combined effects of water spray and gravity. However, problems such as excessively long inlet ducts, numerous bends, impeller wear and scaling, and motor malfunctions can cause a decrease in air velocity. When the gas velocity in the inlet duct is lower than the design minimum velocity, fine particles in the dust will settle, especially at bends. If not addressed promptly, these accumulated particles will form a hard shell that adheres to the bottom of the duct and at bends, hindering dust flow and ultimately affecting the efficiency of the entire dust collection system. Traditional cleaning methods involve manually clearing the inside of the duct or tapping it with tools on the outside, combined with water flushing, to remove accumulated dust. However, this method is labor-intensive, creates a harsh working environment, and easily leads to secondary scaling in the duct. Therefore, this method is unsuitable for cleaning dust from long inlet ducts, ducts with high-viscosity dust prone to scaling, and ducts that are difficult to access. Utility Model Content

[0003] This invention provides a dust removal device for long-distance dust removal air inlet ducts to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dust removal device for a long-distance dust removal air inlet pipe includes a dust removal air inlet pipe, a dust removal main pipe is horizontally arranged inside the dust removal air inlet pipe, a plurality of dust removal branch pipes are evenly distributed vertically at the bottom of the dust removal main pipe, and an air compressor is connected to one side of the dust removal main pipe that extends out of the dust removal air inlet pipe.

[0006] Furthermore, a solenoid valve is installed between the main dust removal pipe extending from the dust removal air inlet pipe and the air compressor, and the solenoid valve is also connected to a time relay.

[0007] Furthermore, a horizontal support frame is provided inside the dust removal air inlet pipe, and the dust removal main pipe is fixedly installed on the top of the support frame.

[0008] Furthermore, each of the ash removal branch pipes is provided with a duckbill opening at its bottom.

[0009] This utility model has the following beneficial effects:

[0010] This utility model provides a dust removal device for long-distance dust collection inlet ducts, mainly composed of a main dust removal pipe, branch dust removal pipes, an air compressor, a solenoid valve, a support frame, and a time relay. By installing a horizontal main dust removal pipe inside the dust collection inlet duct and evenly distributing multiple branch dust removal pipes with duckbill nozzles at the bottom of the main pipe, the device effectively achieves periodic automatic cyclic cleaning of accumulated dust in the dust collection inlet duct through the combined control of the time relay and solenoid valve on high-pressure air. This significantly improves cleaning efficiency. Furthermore, the main dust removal pipe and the dust collection inlet duct are of equal length and parallel to each other, thereby extending the cleaning distance and further ensuring the cleaning effect. This invention solves the problem of low efficiency and poor results in cleaning long-distance dust collection inlet ducts in mineral processing, which currently relies on manual unblocking of the inner wall of the duct or tapping with tools on the outside of the duct, combined with water flushing.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-3 As shown, a dust removal device for a long-distance dust removal air inlet pipe includes a dust removal air inlet pipe 7. A dust removal main pipe 1 is horizontally arranged inside the dust removal air inlet pipe 7. Multiple dust removal branch pipes 2 are evenly distributed vertically at the bottom of the dust removal main pipe 1. An air compressor 3 is connected to one side of the dust removal main pipe 1 that extends out of the dust removal air inlet pipe 7.

[0018] A solenoid valve 4 is installed between the dust removal main pipe 1 extending out of the dust removal air inlet pipe 7 and the air compressor 3. The solenoid valve 4 is also connected to a time relay 6.

[0019] A horizontal support frame 5 is provided inside the dust removal air inlet pipe 7, and the dust removal main pipe 1 is fixedly installed on the top of the support frame 5.

[0020] Each of the ash removal branch pipes 2 is equipped with a duckbill nozzle 8 at its bottom.

[0021] The dust removal main pipe 1 and the support frame 5 are installed in the same direction as the dust removal air inlet pipe 7 and are of equal length. The diameter of the dust removal main pipe 1 is 50mm. It is installed on the support frame 5 by welding, which can ensure that the dust removal range covers any part of the air inlet pipe.

[0022] The diameter of the cleaning branch pipe 2 is 32mm, and the spacing between the cleaning branch pipes 2 is 1m. They are installed on the cleaning main pipe 1 by welding.

[0023] The outlet of the dust removal branch pipe 2 is processed into a duckbill-shaped opening 8, which can effectively increase the pressure of the high-pressure air at the outlet, reduce energy consumption, and ensure the dust removal effect.

[0024] The time relay 6 is model DH48S-S. The time relay 6 can set the working cycle of the solenoid valve 4. By controlling the solenoid valve 4 to cycle on and off in a cycle, automatic cyclic cleaning can be achieved.

[0025] In practical application, the support frame 5 is welded inside the dust removal inlet pipe 7. The main cleaning pipe 1, with a diameter of 50mm, is welded to the support frame 5. Below the main cleaning pipe 1 and perpendicular to it, several cleaning branch pipes 2 with a diameter of 32mm are welded at intervals of 1m. The main cleaning pipe 1 is connected to the air compressor 3 through a solenoid valve 4. The working cycle of the solenoid valve 4 is set in the time relay 6. Through the periodic switching of the solenoid valve 4, the dust removal system inlet pipe is automatically cleaned in a cycle. This effectively realizes the regular cleaning of the dust removal inlet pipe 7 by using high-pressure air through the opening of the solenoid valve 4 at fixed time intervals. Furthermore, the main cleaning pipe 1 and the dust removal inlet pipe 7 are of equal length and parallel to each other, further extending the cleaning distance of the airflow and ensuring the cleaning effect. Therefore, this device has good practicality.
