Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a special air flotation device for industrial wastewater treatment. Background Art

[0002] Air flotation equipment is a type of water treatment equipment that introduces or generates a large number of fine bubbles in water, allowing air to attach to suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water, and uses the buoyancy principle to make it float on the water surface, thereby achieving solid-liquid separation. Existing air flotation equipment has a low efficiency in cleaning floating dirt floating on the water surface, and it is not convenient to adjust the depth of the cleaning component as needed, thereby reducing the cleaning effect on floating objects of different thicknesses.

[0003] The publication (announcement) number is CN220283693U, which discloses a high-efficiency flotation device for industrial wastewater treatment, belonging to the technical field of flotation equipment, including a pool body, a transverse movement mechanism and a scraping mechanism, wherein the front outer wall of the pool body is installed with a side plate, the upper side of the side plate is installed with a highly efficient transverse movement mechanism, and the lower side of the rear end of the transverse movement mechanism is installed with a scraping mechanism that is convenient for adjusting the height position. The utility model drives the rod body connected to the right end to rotate by controlling the operation of the motor at the outer end, and the sleeve plate engages and moves to the right stably and quickly under the limit of the limit groove, thereby driving the scraping assembly to efficiently clean the dirt floating on the surface of the pool body. When it is necessary to clean floating objects of different thicknesses, the panel is pulled inward at the same time to move inward in the slot to drive the plug rod to move out of the slot, and the scraper is pulled upward to adjust the height position, so as to complete the adjustment of the scraper height position, which is convenient for efficient cleaning of floating objects of different thicknesses and improves the practicality of the flotation device.

[0004] Although the above scheme improves the cleaning efficiency and cleaning effect of floating dirt on the water surface, the scraping component lacks auxiliary guidance and its stability is poor, and the scraper height adjustment requires multi-point unlocking and re-locking operations. The scraper height adjustment process is cumbersome and laborious. For this reason, we propose a special flotation equipment for industrial wastewater treatment. Utility Model Content

[0005] The main purpose of the utility model is to provide a special air flotation equipment for industrial wastewater treatment, which solves the problems of poor stability of the scraping component due to lack of auxiliary guidance and complicated and laborious scraper height adjustment process by setting a mobilization unit and an adjustment scraper unit.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions: a special flotation equipment for industrial wastewater treatment, comprising an air flotation tank and a dissolved air conveying assembly and a collecting assembly arranged at both ends of the air flotation tank, and also comprising: a maneuvering unit arranged on the side wall of the air flotation tank and an adjustment scraping unit arranged on the maneuvering unit;

[0007] The transfer unit includes a horizontal lead screw, a support block, a support frame, a servo motor, and a horizontal guide rod.

One of the support blocks is threadedly connected to the horizontal lead screw. The support frame is in a "U" shape, and its opposite concave surfaces are respectively connected to the end faces of the two support blocks. The servo motor is fixedly installed on the horizontal strip-shaped installation groove, and its output end is connected to the end face of the horizontal lead screw. The horizontal guide rod is fixedly arranged on the other horizontal strip-shaped installation groove and movably penetrates through the other support block;

[0008] The adjustment and slag scraping unit includes a vertical lead screw, a guide block, a support cross bar, and a scraper. On the opposite concave surfaces of the support frame, a vertical strip-shaped installation groove is respectively opened. The vertical lead screw is movably arranged on one of the vertical strip-shaped installation grooves. There are two guide blocks in total. One of the guide blocks is threadedly connected to the vertical lead screw. The support cross bar is fixedly arranged between the two guide blocks. The scraper is fixedly arranged at the bottom end of the support cross bar and is located inside the air flotation tank. One end of the vertical lead screw that extends out of the support frame is fixedly provided with a turntable.

[0009] Preferably, the support frame is located outside the top end of the air flotation tank.

[0010] Preferably, the adjustment and slag scraping unit further includes a vertical guide rod. The vertical guide rod is fixedly arranged on the other vertical strip-shaped installation groove and movably penetrates through the other guide block.
