Description

Technical Field

[0001] This utility model relates to the field of slag-containing fluid filtration technology in the industrial and commercial sector, specifically to a slag-removing device for filtering metal dust. Background Technology

[0002] In my country's existing industrial and commercial sectors, the grinding, polishing, and shot blasting processes for metal products, especially aluminum alloy castings, generate a large amount of dust particles. These particles enter the water tank through the equipment's spray system. Because the water in the tank is recycled, dust particles accumulate continuously, often causing equipment blockages and damage. Furthermore, bacteria easily breed in the water, posing occupational health and safety risks to operators who are constantly exposed to the spray water curtain. Another method for dust control is to use pulse-jet baghouse dust collectors. This equipment can efficiently remove the large amounts of dust generated during steel production, meeting stringent environmental emission standards. However, this equipment has high manufacturing costs and occupies a large volume in the factory, resulting in low economic efficiency in actual use and failing to align with the principles of energy conservation and environmental protection in production.

The output end of the scraper reducer motor 1 extends into the interior of the top cover 2 to connect to the scraper mechanism 4. The scraper mechanism 4 is located inside the filter element 5. The filter element 5 is installed inside the filter body 3. The filter body 3 includes a water inlet 301, a filter element support plate 302, a clean water space 304, a water outlet 305, and a slag-holding funnel 303. The flange of the filter element support plate 302 and the slot 701 of the filter element base plate 7 together fix the filter element 5 and form a clean water space 304. Specifically, the filter element support plate 302 and the upper flange of the filter element 5 are fastened together by bolts. The water inlet 301 is located at the top of the filter body 3, and the water outlet 305 is located at the bottom of the clean water space 304. The spiral auger conveying mechanism 8 and the sludge funnel 303 are connected by a flange. A manual gate valve is provided at the connection between the sludge funnel 303 and the spiral auger conveying mechanism 8. By periodically opening the gate valve, the spiral auger conveying mechanism 8 can clean the dust particles in the sludge funnel 303, avoiding the problems of low efficiency and impact on the health of workers caused by manual cleaning.

[0019] Specifically, the scraping mechanism 4 in this embodiment includes a coupling 401, a scraper brush 402, and a rotating shaft 403. The coupling 401 is used to connect the rotating shaft 403 to the output end of the scraper reduction motor 1. The scraper brushes 402 are staggered on the rotating shaft to clean the inner wall of the filter element 5. The scraper reduction motor 1 is a combination of a motor and a reducer, with a rotation speed of 100-200 rpm.

[0020] In the above embodiment, the filter element base plate 7 includes a slot 701, a plate hole 702, and a shaft seat hole 703. The shaft seat hole 703 is used to receive the rotating shaft 403 in the scraping mechanism 4. The plate hole 702 is located at the bottom of the filter element 5. The outer side of the plate hole 702 is a large round hole, and the inner side is a small round hole. The part that is different from the water purification space 304 is without holes.

The clean water flows into the clean water space 304, while the dust particles remain in the cavity of the filter element 5 and settle into the slag funnel 303 through the plate holes 702. When the dust particles in the slag funnel 303 accumulate to a certain position, the gate valve at the connection between the spiral auger conveying mechanism 8 and the slag funnel 303 is opened. Then, the motor 801 of the spiral auger conveying mechanism 8 is started to discharge the dust particles in the slag funnel 303. At the same time, the scraper reduction motor 1 can be started to brush the filter element 5 through the scraper mechanism 4 to prevent clogging.
