Description

Technical Field

[0001] This utility model relates to the field of cartridge dust collectors, specifically to a self-cleaning cartridge dust collector. Background Technology

[0002] Self-cleaning cartridge dust collectors belong to the field of air purification equipment and are mainly used in industrial production and other scenarios where dust pollution exists. They are used to treat dust-laden gases and separate dust from gas through the filtration effect of the cartridge, thereby achieving the purpose of purifying the gas and collecting dust.

[0003] In existing cartridge dust collectors, the internal space of the dust collection box often lacks a reasonable partition structure, resulting in a chaotic flow path and poor stability of the airflow within the box, which affects the dust collection efficiency of the cartridges. The setting of the air inlet and outlet is not reasonable enough, which can easily cause mutual interference between dust-laden gas and clean gas, reducing the overall dust removal effect.

[0004] The pulse cleaning device is not precise enough and lacks effective status monitoring and display functions, making it difficult to ensure timely and thorough removal of dust from the filter cartridge surface. This leads to a rapid decline in filter cartridge filtration performance and a shortened service life. The dust collection and discharge system is not well coordinated, and there are deficiencies in the connection between the ash hopper, ash discharge valve and ash loading equipment. This can easily lead to dust accumulation and secondary pollution. The cleaning operation is cumbersome, and the transfer of ash loading equipment is not convenient, increasing the intensity of manual operation. Furthermore, the fan settings of some equipment fail to provide continuous and stable power for the airflow circulation in the housing, affecting the continuity of the dust removal process. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a self-cleaning cartridge dust collector. This invention solves the problems of insufficient precision in the control of existing pulse cleaning devices, lack of effective status monitoring and display functions, difficulty in ensuring timely and thorough removal of dust from the filter cartridge surface, leading to a rapid decline in filter cartridge filtration performance and a shortened service life; inadequate coordination between the dust collection and discharge systems, insufficient connection between the ash hopper, ash discharge valve, and ash loading equipment, which easily leads to dust accumulation and secondary pollution; cumbersome cleaning operations; inconvenient transportation of ash loading equipment, increasing manual labor intensity; and the failure of some equipment's fan settings to provide continuous and stable power for airflow circulation within the housing, affecting the continuity of the dust removal process.

[0006] The purpose of this utility model is achieved through the following means: a self-cleaning cartridge dust collector, comprising a dust collection box and a filter cartridge, wherein the filter cartridge is assembled in the inner cavity of the dust collection box, the inner cavity of the dust collection box is provided with a cross-shaped partition, the top two sides of the dust collection box are respectively connected to an air inlet and an air outlet, the inner cavity of the dust collection box is provided with a pulse valve, the output end of the pulse valve is connected to the outside of the filter cartridge, the outside of the pulse valve is respectively provided with a control module and a data display module, the bottom of the inner cavity of the dust collection box is provided with a ash hopper, the discharge port of the ash hopper is connected to an ash discharge valve, the bottom of the inner cavity of the dust collection box is slidably connected to an ash loading cart, and the inner cavity of the dust collection box is provided with a fan.

[0007] Dust-laden gas enters the dust collector through the inlet under the guidance of the fan, passes through the filter cartridges, and then enters the clean air chamber before being discharged through the exhaust outlet along the pipeline. Dust is captured on the surface of the filter cartridges, and as a dust cake forms, the pressure difference gradually increases. When a predetermined value is reached, the control module activates the pulse valve for automatic cleaning. Compressed air is then radially blown away from the dust through the filter cartridges. The dust falls into the ash hopper under gravity and is finally collected in an ash truck through the ash discharge valve. This structure utilizes pulse cleaning technology to maintain stable system airflow and pressure drop, and the filter cartridges use high-efficiency filter media for highly efficient air purification.

[0008] Furthermore, a dust discharge port is provided on the right side of the dust collector housing, and a sealing plate is slidably connected to the inner cavity of the dust discharge port. The dust discharge port can be used with the dust hopper and dust loading cart to facilitate the cleaning of dust, and the sealing plate can ensure the airtightness of the dust collector housing when not being cleaned, preventing dust-laden gas from escaping and ensuring filtration efficiency.

[0009] Furthermore, the dust collector housing has a maintenance slot on the front, and maintenance doors are rotatably connected to both sides of the inner cavity of the maintenance slot. The maintenance doors are located on the front, so that all maintenance access points can be entered from the front of the device, which facilitates the inspection, replacement and maintenance of components such as filter cartridges and pulse valves, improving the convenience and efficiency of equipment maintenance.

[0010] Furthermore, a dust baffle is installed at the top of the inner cavity of the dust collector housing, located directly below the air inlet. The dust baffle buffers and guides the dust-laden gas entering from the air inlet, preventing some large dust particles from directly impacting the filter cartridge, reducing the load on the filter cartridge, extending its service life, and optimizing airflow distribution to ensure uniform filtration.

[0011] Furthermore, the control module is electrically connected to a dust concentration sensor, which is mounted inside the filter cartridge. The control module controls the opening and closing frequency of the pulse valve based on the detection data from the dust concentration sensor. The dust concentration sensor can monitor the dust concentration inside the filter cartridge in real time, and the control module adjusts the cleaning frequency of the pulse valve accordingly to keep the dust cake thickness on the filter cartridge surface within a reasonable range. This ensures filtration efficiency while avoiding energy waste caused by frequent cleaning, achieving intelligent and efficient operation.

[0012] Furthermore, the filter cartridge is made of high-temperature resistant composite filter material, and the outer surface of the filter cartridge has uniformly distributed honeycomb-shaped protrusions. The inner wall of the ash hopper has a conical structure and is coated with a polytetrafluoroethylene (PTFE) anti-stick coating. The output end of the fan is connected to the exhaust port through a silencer pipe, and the outside of the fan is wrapped with a sound-insulating cotton layer. The high-temperature resistant composite filter material of the filter cartridge can be made of PTFE membrane material, which is flame-retardant and anti-static. The honeycomb protrusions increase the filtration area and improve the filtration effect. The conical structure of the ash hopper, combined with the PTFE anti-stick coating, prevents dust adhesion and ensures smooth dust fall. The silencer pipe and sound-insulating cotton layer of the fan effectively reduce operating noise, meeting environmental protection requirements.

[0013] The beneficial effects of this utility model are:

[0014] This self-cleaning cartridge dust collector, by setting a cross-shaped partition in the inner cavity of the dust collection box, can reasonably divide the inner cavity space, which helps to optimize the flow path of air in the box, improve the airflow stability during the dust collection process, and thus improve the dust collection efficiency of the cartridge. The air inlet and air outlet are respectively set on the top two sides, which can make the flow of dust-laden gas and clean gas more orderly, reduce the mutual interference between airflows, and enhance the overall dust collection effect.

[0015] This self-cleaning cartridge dust collector is equipped with a pulse valve that connects to the outside of the filter cartridge. Combined with a control module and a data display module, it enables precise control of the pulse cleaning process, allowing for real-time monitoring of the cleaning status. This ensures that dust on the surface of the filter cartridge is removed promptly and effectively, maintaining good filtration performance and extending the filter cartridge's service life. The ash hopper, ash discharge valve, and ash loading cart work together to effectively collect and conveniently discharge the filtered dust, preventing dust accumulation and secondary pollution, and simplifying the cleaning operation. The ash hopper at the bottom, in conjunction with the ash discharge valve, smoothly discharges the collected dust into the slidingly connected ash loading cart. The sliding design of the ash loading cart facilitates centralized collection and transfer of dust, reducing manual labor intensity. Meanwhile, the fan provides power for airflow circulation within the housing, ensuring continuous and stable dust removal. Attached Figure Description
