Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically to an acid-base adjustment device for wastewater treatment. Background Technology

[0002] Wastewater treatment requires acid-base neutralization to ensure its recycling after further treatment. This process typically involves adding neutralizing agents and mixing them. During mixing, a stirring rod rotates in one direction within the tank. However, this method reduces mixing efficiency and prevents the agents settling at the bottom from quickly dissolving, causing them to clump together and affecting the mixing quality.

[0003] According to the patent document CN217265010U, an acid-base adjustment device for wastewater treatment includes an acid-base adjustment tank and a stirring and mixing assembly for fully reacting the wastewater in the tank with acidic or alkaline substances. The acid-base adjustment tank has a level gauge on its front side, an inlet on one side of its upper end, an acid box fixedly mounted on its upper surface, and an alkali box fixedly mounted on one side of the acid box. The discharge pipes at the lower ends of both the acid and alkali boxes are connected to the interior of the acid-base adjustment tank. In this design, the acid-base adjustment tank vibrates under the impact of wastewater. During the downward movement of the tank, the vibration effectively compresses a buffer spring, which, through its contraction, effectively buffers the force. However, while this design achieves buffering, it cannot simultaneously circulate and stir the wastewater while filtering it, resulting in inconvenience during use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an acid-base adjustment device for sewage treatment to solve the problems mentioned in the background art. The utility model has a novel structure. When in use, the sewage inside the tank enters the interior of the fixed cylinder under the pump, and is squeezed out from the inside. When the sewage is sprayed out through the opening, it is tumbling and stirring, and at the same time, it is filtered by the filter plate.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an acid-base adjustment device for sewage treatment, comprising a base, a barrel fixed to the top of the base, a cover plate movably installed on the top of the barrel, ring seats fixed on both the cover plate and the barrel, fixing bolts fixed between the ring seats, a tank body fixed to the top of the cover plate, the tank body including an acid storage tank and an alkali storage tank, an extraction pipe fixed to the side of the barrel body, one end of the extraction pipe installed inside the barrel body, a water pump fixed to the extraction pipe, and a circulation pipe fixed to the water pump.

[0006] Furthermore, a fixed cylinder is fixed inside the barrel, one end of the circulation pipe is fixed to the fixed cylinder, the fixed cylinder has an opening, and a movable seat is movably installed on the top of the fixed cylinder.

[0007] Furthermore, a filter screen is fixedly installed inside the opening, a fixing tube is fixed to the top of the movable seat, and a reinforcing rod is fixed between the fixing tubes.

[0008] Furthermore, a pump body is fixed to the bottom of the tank, and a reinforcing pipe is fixed to the bottom of the pump body. The reinforcing pipe is movably installed at one end of the fixed pipe.

[0009] Furthermore, a fixing ring is fixed on the fixing cylinder, a collection seat is movably installed on the top of the fixing ring, a filter plate is fixedly installed on the collection seat, and the collection seat is installed on the fixing cylinder through a mounting hole.

[0010] Furthermore, an inlet pipe and a drain pipe are fixed to the side of the barrel, and a connecting pipe is fixed to the bottom of the movable seat, with a through hole on the connecting pipe.

[0011] Furthermore, a fixed column is fixed to the bottom of the movable seat, and a piston seat is fixed to one end of the fixed column. The piston seat is movably installed inside the fixed cylinder.

[0012] Furthermore, the tank has an observation window with scale lines fixed to its side, and an electronic pH sensor is fixedly installed inside the tank.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, the wastewater inside the tank is drawn in by the water pump and enters the interior of the fixed cylinder. It is squeezed out from the inside and sprayed out. When the wastewater is sprayed out through the opening, it is tumbling and stirring, and at the same time, it is filtered by the filter plate.

[0015] 2. In this utility model, the water inside the barrel pushes the acid or alkali solution discharged from the connecting pipe to flow together under the tumbling. At the same time, the flow and compression realize the stirring and mixing between the liquids. As the sewage tumbles and stirs inside the barrel, bubbles are generated at the top of the sewage. The bubbles carry impurities to float upward and enter the collection seat from the side and are collected.

[0016] 3. In this utility model, the movable seat is driven to move upward by the fixed column. The upward movement of the piston seat scrapes against the inner wall of the fixed cylinder, and the impurities on the inner wall of the filter screen are scraped and cleaned as the piston seat moves upward.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: an acid-base adjustment device for sewage treatment, including a base 1, a tank 2 fixed to the top of the base 1, a cover plate 8 movably installed on the top of the tank 2, ring seats 9 fixed on both the cover plate 8 and the tank 2, and fixing bolts 10 fixed between the ring seats 9, a tank 11 fixed to the top of the cover plate 8, the tank 11 including an acid storage tank and an alkali storage tank, an extraction pipe 5 fixed to the side of the tank 2, one end of the extraction pipe 5 installed inside the tank 2, a water pump 4 fixed to the extraction pipe 5, a circulation pipe 3 fixed to the water pump 4, a fixed cylinder 13 fixed inside the tank 2, one end of the circulation pipe 3 fixed to the fixed cylinder 13, an opening 20 on the fixed cylinder 13, and a movable seat 14 movably installed on the top of the fixed cylinder 13, which allows the piston seat 25 to be easily extracted from the inside of the fixed cylinder 13 after the movable seat 14 is moved upwards.

[0026] In this embodiment, a filter screen 21 is fixedly installed inside the opening 20, a fixed tube 15 is fixed to the top of the movable seat 14, a reinforcing rod 16 is fixed between the fixed tubes 15, a pump body is fixed to the bottom of the tank 11, a reinforcing tube is fixed to the bottom of the pump body, the reinforcing tube is movably installed at one end of the fixed tube 15, a fixed ring 19 is fixed to the fixed cylinder 13, a collection seat 12 is movably installed on the top of the fixed ring 19, a filter plate 17 is fixedly installed on the collection seat 12, and the collection seat 12 is installed on the fixed cylinder 13 through the mounting hole 18. After the bubbles carry impurities to fall onto the filter plate 17, the filter plate 17 filters and collects the impurities, and the wastewater falls back down through the filter plate 17 to undergo a stirring reaction.

[0027] In this embodiment, an inlet pipe 7 and a drain pipe 6 are fixed to the side of the barrel 2. A connecting pipe 22 is fixed to the bottom of the movable seat 14. A through hole 23 is opened on the connecting pipe 22. A fixing column 24 is fixed to the bottom of the movable seat 14. A piston seat 25 is fixed to one end of the fixing column 24. The piston seat 25 is movably installed inside the fixed cylinder 13. An observation window is opened on the tank 11. A scale line is fixed to the side of the observation window. An electronic pH detection sensor is fixedly installed inside the barrel 2. The electronic pH detection sensor is a prior art device used to detect the acidity and alkalinity in sewage.

[0028] In use, wastewater enters the tank 2 through the inlet pipe 7. The water pump 4 is activated to generate suction. The pump 4, through the extraction pipe 5, moves and pressurizes the wastewater between the tank 2 and the fixed cylinder 13, then directs it into the circulation pipe 3. The circulation pipe 3 pushes the wastewater outward from the inner wall of the fixed cylinder 13. Under pressure, the wastewater is filtered and squeezed out through the opening 20. During discharge, it passes through the filter screen 21. The discharged water collides with the water inside the tank 2, causing turbulence and subsequent mixing. When acid or alkali needs to be added, appropriate amounts are introduced through the tank 11. The acid or alkali enters the fixed pipe 15 through the support pipe and is discharged through the through-hole 23 via the fixed pipe 15 and connecting pipe 22. The wastewater and acid / alkali are then squeezed through the opening 20. The squeezing and subsequent tumbling facilitate the rapid mixing of wastewater and acid / alkali. During the tumbling and stirring of the wastewater, bubbles are generated at the top, which carry impurities to the surface. As the number of bubbles increases, their height increases. Once the height of the bubbles exceeds the top of the collection seat 12, the bubbles flow into the interior of the collection seat 12. After the bubbles and impurities enter the interior of the collection seat 12, they are filtered again. After the cover plate 8 is removed, the collection seat 12 and the movable seat 14 are exposed. The impurities are removed and cleaned by moving the collection seat 12 upward. Moving the movable seat 14 upward causes the fixed column 24 to drive the piston seat 25 to move upward for removal. During removal, the inner wall of the fixed cylinder 13 is scraped. After scraping, the filter screen 21 is cleaned.
