Description

Technical Field

[0001] The utility model belongs to the field of dust collectors, and in particular relates to a spray water mist type dust collector. Background Art

[0002] When exhaust gas is discharged from factories, it needs to be purified and qualified before it can be discharged.

[0003] Chinese patent publication number CN218608642U discloses a spray dust collector. Exhaust gas enters the tower through an air inlet and flows upward within the tower. A spray pump activates, drawing liquid from the treatment liquid tank through a second pipe to a nozzle. The upward-flowing exhaust gas is sprayed and discharged through the air outlet. Liquid dripping from the tower flows through the bottom of the treatment liquid collector into the treatment liquid tank. After settling at the bottom of the treatment liquid tank, it is pumped away by the spray pump again, preventing impurities from entering the spray system.

[0004] However, in the above-mentioned spray dust collector, the treated water is subjected to sedimentation treatment in the treatment liquid tank. Since wastewater continuously flows into the treatment liquid tank, the continuous water flow makes it difficult for the wastewater in the treatment liquid tank to settle, which will cause a large amount of wastewater to gradually flow into the sedimentation tank, increasing the use of water resources and the volume of the treatment liquid tank, thereby increasing the overall volume of the device.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a spray water mist type dust collector.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A spray water mist dust collector includes a treatment box and a sewage tank connected to one side of the treatment box. A partition plate is provided between the sewage tank and the treatment box. The partition plate divides the sewage tank into a sewage area and a clean water area. A baffle is provided in the clean water area. A filter screen and a guide box are provided on one side of the partition plate. A slag discharge port is provided at the bottom end of the guide box. A slag inlet connected to the slag discharge port is provided on the upper side of the baffle. An impeller is rotatably provided on one side of the filter screen. A transmission shaft is provided in the middle of the impeller. The transmission shaft passes through the filter screen and is provided with a scraper member located in the guide box at one end.

[0009] Optionally, the scraper member includes a circular plate fixed to one end of the transmission shaft located in the guide box, and a plurality of push plates arranged in a circular array on the side of the circular plate, and the length of the push plates is greater than the radius of the filter screen.

[0010] Optionally, the baffle divides the sewage area into an inlet area and a sedimentation area. A water inlet is provided on one side of the guide box, and the water inlet corresponds to the filter screen. A drain valve connected to the sedimentation area is connected to the bottom of the sewage tank. A dividing guide plate is provided in the treatment box, and a drain pipe connected to the water inlet area is connected to one side of the treatment box. A water inlet hole connected to the clean water area is provided at the bottom of the treatment box.

[0011] Optionally, multiple air inlet pipes are connected to the middle of the processing box, a suction fan is connected to the upper part of the processing box, a spray mechanism is provided in the processing box, the spray mechanism includes a water pump connected to the lower part of the processing box, and multiple spray pipes connected to the processing box. The multiple spray pipes are connected to the water pump, and the spray pipes are located above the air inlet pipe. A main water pipe is connected to the side of the processing box, and multiple spray pipes are connected to the main water pipe. A connecting pipe is provided between the water pump and the main water pipe.

[0012] Optionally, a perspective window is provided on one side of the processing box, and a touch panel is provided on the other side of the processing box.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] The wastewater generated by the treatment box is discharged into the baffle in the sewage tank, enters the guide box, is filtered through the filter, and the filtered water is discharged into the treatment box. The flow of filtered water drives the impeller to rotate, and then drives the scraper to rotate, pushing the filtered impurities out of the filter. The impurities fall in the guide box and are discharged under the baffle through the slag discharge port and the slag inlet. By setting the baffle, the wastewater is prevented from being discharged directly under the baffle, which causes the impurities precipitated under the baffle to float up and cause repeated filtration of the impurities. The filter is continuously cleaned by the scraper, which facilitates the continuous filtration of the filter to reduce the amount of wastewater generated, reduce the water consumption of the device, and reduce the overall volume of the device.
