Description

Technical Field

[0001] The invention relates to the field of filtering and cleaning devices, in particular to a filtering and cleaning device for printing and dyeing wastewater. Background Art

[0002] Printing and dyeing wastewater is wastewater discharged from printing and dyeing, wool dyeing and finishing, and silk factories that process cotton, linen, chemical fibers and their blended products, and silk. The amount and quality of printing and dyeing wastewater vary with the type of fiber and processing technology. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the difficult-to-treat industrial wastewaters. The wastewater contains dyes, slurries, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc.

[0003] Nowadays, printing and dyeing wastewater filtering and cleaning equipment generally uses filter plates or filter meshes to filter solid substances in printing and dyeing wastewater. However, after long-term filtration, the filter mesh is prone to clogging. Therefore, the filter mesh or filter plate needs to be cleaned. The conventional cleaning method generally closes the water inlet pipe first to clean the filter mesh or filter plate. However, it will affect the filtration speed of the sewage. Alternatively, the water inlet pipe is not closed and cleaning is performed directly in the sewage. However, this method easily causes impurities to re-clog the filter mesh or filter plate. For this reason, a printing and dyeing wastewater filtering and cleaning equipment is needed to facilitate the cleaning of the filter mesh or filter plate. Summary of the invention

[0008] Preferably, the adjusting mechanism includes a connecting block, a rotating shaft, a bottom gear, a top gear, a driven rack, a baffle, a spare filter plate and a second round rod; the end of the support tube close to the water inlet pipe is connected to the connecting block; the side wall of the connecting block is rotatably connected to the rotating shaft; the bottom end of the rotating shaft is connected to the bottom gear; the top end of the rotating shaft is connected to the top gear; the side wall of the top gear is meshed with the driving rack; the end of the support tube close to the water inlet pipe is connected to two symmetrically distributed second round rods; the side wall of the second round rod is slidably connected to the baffle; the top end of the baffle is connected to the driven rack; the side wall of the bottom gear is meshed with the driven rack; the inner wall of the support tube is connected to the spare filter plate.

[0009] Preferably, the main filter plate and the spare filter plate are respectively located on both sides of the partition plate, and the diameter of the top gear is smaller than the diameter of the bottom gear.

[0010] Preferably, the cleaning mechanism includes a bracket, a hydraulic cylinder, a scraper, a through hole, an electric valve, a collection box and a box door. The top end of the support tube is connected to the bracket, the top end of the bracket is connected to the hydraulic cylinder, the output end of the hydraulic cylinder is connected to the scraper, the side wall of the support tube is provided with a through hole, the side wall of the through hole located at the side wall of the bottom end of the support tube is provided with an electric valve, the bottom end side wall of the support tube is connected to the collection box, and the side wall of the collection box is provided with a box door that can be rotatably opened.

[0011] Preferably, an opening is provided at the top of the collecting box, the through hole is located above the collecting box, and the scraper is located inside the through hole.

[0013] The beneficial effects of the present invention are:

[0014] 1) The water inlet pipe leads to untreated sewage, so that the sewage enters the treatment tank. The sewage will be filtered by the main filter plate to filter out impurities. At the same time, the shield plate will block the spare filter plate at this time, so that the sewage cannot be filtered from the spare filter plate. The sewage will pass through the main filter plate, enter the inside of the support pipe, and flow to the outlet pipe to enter the next sewage treatment. When the sewage flows out of the support pipe, it will be blocked and guided by the guide plate, so that the sewage will not flow directly to the inside of the support pipe at the spare filter plate.

[0015] 2) After the main filter plate is blocked, the first push rod motor is started, and the first push rod motor pulls the main filter plate to move backward along the first round rod. At the same time, the main filter plate drives the connecting rod to move backward. When the main filter plate moves toward one side of the water inlet pipe to be aligned with the rear side of the through hole, the movement of the main filter plate is stopped. At the same time, the connecting rod drives the driving rack to move backward, and the driving rack drives the top gear to rotate, and the top gear drives the rotating shaft to rotate, and the rotating shaft drives the bottom gear to rotate, and the bottom gear drives the driven rack to move, so that the driven rack moves along the second round rod to the main filter plate, thereby blocking the opening of the compartment of the support pipe where the main filter plate is located, so that the main filter plate can be separated from the continuous impact of sewage, and the opening of the support pipe at the spare filter plate is opened, so that the spare filter plate continues to filter, avoiding the situation of delaying the continuous filtration of sewage, and taking advantage of the fact that the diameter of the top gear is smaller than the diameter of the bottom gear, the moving distance of the driving rack is smaller than the distance of the driven rack.

[0016] 3) When the main filter plate moves toward the side of the water inlet pipe and is aligned with the rear side of the through hole, start the hydraulic cylinder and the electric valve to push the scraper downward. The scraper will scrape off the impurities attached to the side wall of the main filter plate facing the water inlet pipe, and push the impurities into the through hole below, so that the impurities can pass through the through hole below and enter the collection box, completing the removal and collection of impurities. The box door can be opened later to clean the impurities. BRIEF DESCRIPTION OF THE DRAWINGS
