Description

Technical Field

[0001] This utility model relates to the field of air purification technology in production workshops, specifically a dust adsorption and purification dust collection device for workshops. Background Technology

[0002] Workshop dust adsorption and purification devices are environmental protection equipment designed to address pollutants such as suspended particulate matter and harmful gases generated in industrial production. Their core function is to reduce workshop air pollution, protect the occupational health of workers, and meet environmental emission standards. With the increasing sophistication of manufacturing and stricter environmental policies, this technology effectively solves the problems of high energy consumption, secondary pollution, and complex maintenance associated with traditional dust removal systems through efficient capture, separation, and harmless treatment of dust. It is particularly suitable for industries prone to generating hazardous dust, such as metal processing, wood manufacturing, and chemicals. It offers multiple socio-economic benefits, including improving the production environment, preventing occupational diseases, and reducing industrial waste emissions, making it an important technological means to promote the coordinated development of green manufacturing and safe production.

[0003] The existing technology has the following shortcomings: The existing technology, "A dust adsorption device for a cleanroom", published by CN209188360U, "includes an adsorption cylinder, a connecting hood and a blower. One end of the adsorption cylinder is fixedly connected to the connecting hood, and one end of the connecting hood is fixedly connected to the blower. A stepped groove is opened on the inner side wall of the adsorption cylinder. A dust inlet plate, a coarse filter membrane layer, a fine filter membrane layer and a micro filter membrane layer are sequentially engaged in the inner cavity of the adsorption cylinder at the end away from the connecting hood. The coarse filter membrane layer, the fine filter membrane layer and the micro filter membrane layer are sequentially engaged in the stepped groove. Multiple through holes are opened on the side wall of the adsorption cylinder. A threaded groove is opened on the edge of the dust inlet plate. The dust inlet plate is fixed in the inner cavity of the adsorption cylinder by screws. Multiple dust inlet holes are opened on the dust inlet plate. A dust inlet hood is fixedly connected to the inner side wall of the dust inlet hole.

[0004] The aforementioned structure, by incorporating an adsorption cylinder, a connecting hood, and a blower, can adsorb dust within a cleanroom. However, this structure employs a single dry adsorption method, where dust comes into direct contact with the filter structure. This results in frequent replacement of the filter elements, and the fixed design of the filter elements makes independent disassembly and assembly difficult. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust adsorption and purification dust collection device for workshops, which solves the problems of slow disassembly and assembly of filter elements and poor efficiency of single dry adsorption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a workshop dust adsorption and purification dust collection device, comprising a dry adsorption chamber, a water pump, and a water tank, wherein the water pump is disposed at the side end of the dry adsorption chamber, and the water tank is disposed at the side end of the water pump.

[0007] A wet pretreatment frame is provided on the side of the dry adsorption chamber, and a filter plate is provided inside the dry adsorption chamber.

[0008] The wet pretreatment frame also includes a water collection tank and a pressurized nozzle. The water collection tank is located at the bottom of the wet pretreatment frame, and the pressurized nozzle is fixedly installed at the top of the wet pretreatment frame, with the nozzle extending through the top of the wet pretreatment frame.

[0009] As a preferred technical solution of this utility model, the water collection tank is positioned corresponding to the pressurized nozzle and its size is larger than the water droplet spray range. A through hole is provided on the side end of the water collection tank, and a pipe structure is connected to the outside of the through hole.

[0010] As a preferred technical solution of this utility model, a pipeline is provided to connect the water tank, the water pump and the pressurized nozzle, wherein six independent nozzles are provided at the pressurized nozzle position.

[0011] As a preferred technical solution of this utility model, the dry adsorption chamber further includes a sealing paddle, a spring column, and a gasket. The sealing paddle is movably connected to the side end of the dry adsorption chamber, the spring column is inserted into the inside of the dry adsorption chamber, and the gasket is sleeved around the spring column.

[0012] As a preferred technical solution of this utility model, the sealing lever, spring column and gasket are all installed in a symmetrical structure and are located on the upper and lower sides of the dry adsorption chamber respectively.

[0013] As a preferred technical solution of this utility model, the filter plate is provided in four sets and inserted into the dry adsorption chamber. Its single structure is a rectangular block structure, and the upper and lower sides of the one end facing outward are provided with vertically extending block structures. A through circular hole is opened in the middle of the block structure.

[0014] As a preferred technical solution of this utility model, the filter materials in the middle of the filter plate are different. Starting from the filter plate near the wet pretreatment frame, the materials are metal mesh, activated carbon, HEPA filter material and dustproof filter cotton, respectively.

[0015] Compared with the prior art, this utility model provides a workshop dust adsorption and purification dust collection device, which has the following beneficial effects:

[0016] A dust adsorption and purification dust collection device for workshops comprises filter plates, a wet pretreatment frame, pressurized nozzles, a water collection tank, spring columns, and gaskets. In use, the device is installed within the workshop ventilation system, with extension pipes on both sides connecting the filter plates to the operating duct of the exhaust fan. A water pump draws water from a tank and delivers it through pipes to the pressurized nozzles, spraying it downwards. The water droplets adsorb dust particles in the air and fall into the water collection tank, then are discharged through a pipe at the side of the tank. The air adsorbed by the water droplets is then subjected to dry filtration after passing through the filter plates. When the filter plates need replacement, the operator rotates the sealing lever to remove any obstructions from the side of the filter plate. The springs around the spring columns then spring back, pushing the filter plates out from the side of the dry adsorption chamber. The four sets of filter plates can be replaced as needed; simply press the filter plate and rotate the sealing lever to block its side.

[0017] Through the above-described setup and process, this equipment, compared to current workshop dust adsorption and purification devices, utilizes a drawer-type filter structure instead of the traditional fixed filter structure. This makes filter plate replacement more flexible, allowing for the replacement of individual filter structures as needed and significantly improving disassembly and assembly speed. The combination of a dry adsorption chamber and a wet pretreatment frame, along with dry and wet treatment methods, improves dust adsorption efficiency and reduces the frequency of filter element replacement.
