Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic pH adjustment tank for wastewater treatment. Background Technology

[0002] In the field of wastewater treatment, various types of wastewater, due to their different properties, often require different treatment methods. In some scenarios, the wastewater needs to be adjusted to a suitable pH range before further treatment. When adjusting the pH of wastewater, a pH adjustment tank is required. Traditional pH adjustment tanks often inject pH adjusters through the top inlet. This method results in an extremely low reaction rate. While the upper layer of wastewater has fully reacted, the lower layer may still be unreacted. Furthermore, the concentration of the pH adjuster decreases significantly after entering the lower layer, further increasing the difficulty of the reaction. Uneven reaction can also affect the judgment of whether the overall pH adjustment of the wastewater has been completed.

[0003] Publication No. CN 213803078 U discloses a pH adjusting tank for wastewater treatment. By integrating a mixing mechanism and a stirring mechanism, when a pH adjusting agent needs to be injected into the tank, the reaction liquid can be uniformly injected into the tank through outlet holes evenly distributed in each layer inside the tank. Combined with a heating wire installed in the same location, driven by a stirring drive shaft, the wastewater mixture can be fully and uniformly heated and reacted, effectively improving the sufficiency and rate of the reaction. Simultaneously, the horizontal and vertical scrapers effectively prevent the adhesion of solid or flocculent substances generated during the reaction to the inner wall of the adjusting tank. However, this patent still has the following problems in practical use: Although the pH adjustment tank for wastewater treatment can evenly inject the pH adjuster into the reaction liquid through the outlet holes that are evenly distributed in each layer inside the tank, thereby improving the degree of reaction and the reaction rate, the solid or flocculent substances produced by the reaction will adhere to the outlet holes. Long-term adhesion of solids and flocculent substances will lead to blockage of the outlet holes, which is not only detrimental to the uniform spraying of the pH adjuster, but also affects the pH adjustment efficiency of the wastewater.

[0004] Therefore, an automatic pH adjustment tank for wastewater treatment is proposed to solve the problems mentioned above. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This wastewater treatment automatic pH adjusting tank uses a lead screw sleeve that moves back and forth on the outside of the reciprocating lead screw, simultaneously driving the first and second cleaning rings to rise and fall, thereby cleaning the surface of the spray pipe and preventing impurities and flocculent deposits from adhering to the surface of the spray pipe, thus avoiding blockage. The internal space of the quantitative feeding box is evenly divided into several portions using a feeding rotating plate and a feeding rotating disc, and an automatic feeding pump adds a quantitative amount of pH adjusting agent to the quantitative wastewater, facilitating pH adjustment of the wastewater. The specific details are as follows: 1. By setting up an automatic feeding mechanism, not only can a rotating motor drive a rotating worm gear, but the meshing connection between the worm gear and the worm wheel also drives the distribution cylinder and distribution pipe to rotate. Furthermore, the meshing connection between the drive gear at the bottom of the distribution pipe and the meshing gear ring allows the top rotating disc to both revolve and rotate the spray pipe, facilitating uniform mixing of the wastewater. Simultaneously, it allows for the uniform pumping of pH adjuster from inside the spray pipe, ensuring even distribution of the pH adjuster throughout the wastewater, thus facilitating wastewater treatment. The pH adjustment utilizes the meshing connection between the driving gear and the driven gear, causing the driven gear to drive the reciprocating screw to rotate. At the same time, the screw sleeve moves back and forth on the outside of the reciprocating screw, causing the first and second cleaning rings to move up and down, thereby cleaning the surface of the spray pipe and preventing impurities and flocculent matter from adhering to the surface of the spray pipe, which would lead to clogging of the spray pipe. The cleaning scrapers at the top and bottom of the second cleaning ring can clean the inner wall of the regulating cylinder, preventing impurities from adhering to the inner wall of the regulating cylinder, which is not conducive to the pH adjustment of wastewater. 2. By setting up an automatic feeding mechanism, the pH adjuster can be injected into the mixing cylinder through the injection port. The mixing motor is started to drive the mixing auger and mixing support to rotate. The mixing auger, mixing rod and stirring fork can be used to uniformly mix the pH adjuster. At the same time, the feeding motor is started to drive the feeding rotating plate and feeding rotating disc to rotate. The feeding rotating plate and feeding rotating disc are used to evenly divide the internal space of the quantitative feeding box into several parts. With the help of the automatic feeding pump, a quantitative amount of pH adjuster is added to the wastewater, which is convenient for pH adjustment of the wastewater. Attached Figure Description

[0020] Working principle: Before using this type of automatic pH adjusting tank for wastewater treatment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the rotating motor 104 drives the rotating worm gear 122 to rotate. Utilizing the meshing connection between the rotating worm gear 122 and the rotating worm wheel 105, the rotating worm wheel 105 drives the distribution cylinder 106 and the distribution pipe 107 to rotate. Utilizing the meshing connection between the drive gear 108 at the bottom of the distribution pipe 107 and the meshing gear ring 109, not only can the top rotating disk 110 drive the spray pipe 112 to revolve, but it can also drive the spray pipe 112 to rotate on its own axis, facilitating the uniform distribution of wastewater. The agitation process simultaneously pumps the pH adjuster evenly from the inside of the spray pipe 112, ensuring its uniform distribution in the wastewater and facilitating pH adjustment. Secondly, utilizing the meshing connection between the driving gear 108 and the driven gear 111, the driven gear 111 drives the reciprocating screw 113 to rotate. Simultaneously, the screw sleeve 114 reciprocates outside the reciprocating screw 113, causing the first cleaning ring 115 and the second cleaning ring 116 to move up and down, thereby adjusting the pH of the spray pipe 112. The surface of the spray pipe 112 is cleaned to prevent impurities and flocculent matter from adhering to the surface of the spray pipe 112, which could cause blockage. The cleaning scrapers 117 at the top and bottom of the second cleaning ring 116 can clean the inner wall of the regulating cylinder 101 to prevent impurities from adhering to the inner wall of the regulating cylinder 101, which would be detrimental to the pH adjustment of the wastewater. Finally, the pH adjusting agent is injected into the mixing cylinder 201 through the injection port 202, and the mixing motor 203 is started to drive the mixing auger 204. The mixing support 205 rotates, and the mixing auger 204, mixing rod 206 and stirring fork 207 can uniformly mix the pH adjuster. At the same time, the feeding motor 210 is started to drive the feeding rotating plate 211 and feeding rotating disk 212 to rotate. The feeding rotating plate 211 and feeding rotating disk 212 evenly divide the internal space of the quantitative feeding box 208 into several parts, and cooperate with the automatic feeding pump 209 to add a quantitative amount of pH adjuster to the quantitative wastewater, which facilitates the pH adjustment of the wastewater.
