DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-4 The regulating tank stirring device shown in the figure includes a regulating tank 100 and a pneumatic stirring mechanism. The top of the regulating tank 100 is provided with an inwardly concave regulating chamber 101. The pneumatic stirring mechanism is arranged in the regulating chamber 101. The pneumatic stirring mechanism stirs the landfill leachate in the regulating chamber 101 by blowing air; wherein the pneumatic stirring mechanism includes an air jet pipe 300, the air jet pipe 300 is arranged at the inner bottom of the regulating chamber 101, the outer wall of the air jet pipe 300 is provided with a one-way air jet head 301 for gas ejection, a blower 200 is provided on one side of the regulating tank 100, and the blower 200 is used to transport gas into the one-way air jet head 301; in this embodiment, after the blower 200 is powered on, gas is input into the air jet pipe 300, and the gas is ejected from the multiple one-way air jets on the air jet pipe 300. The air head 301 sprays vertically upward, and the air pressure can be used to stir the sewage (leachate) in the regulating chamber 101, thereby stirring the sewage and achieving uniform water quality and water quantity in the regulating chamber 101. At the same time, since the gas filled into the sewage during the gas stirring process contains oxygen, the sewage contains sufficient dissolved oxygen, which can achieve the removal of organic pollutants through biological adsorption. Moreover, in the process of using gas stirring, bubbles that float upward will be generated in the sewage, which will have the effect of flotation and remove oily substances in the sewage. Therefore, on the premise of meeting the requirements of uniform water quality and water quantity, the pollutants in the sewage can be significantly removed, the load of subsequent sewage treatment can be reduced, the treatment efficiency can be improved, and the operating cost of the sewage treatment line can be reduced.

[0025] Furthermore, a support base 202 is fixedly connected to the side wall of the regulating tank 100, and the blower 200 is fixedly installed on the top of the support base 202. The air outlet of the blower 200 is fixedly connected to a connecting pipe 201, and the blower 200 is connected to one end of the air jet pipe 300 through the connecting pipe 201. There are multiple air jet pipes 300 located inside the regulating chamber 101 and arranged in parallel at intervals. A branch pipe 302 is fixedly provided between the multiple air jet pipes 300 and the connecting pipe 201. The connecting pipe 201 is connected to the multiple air jet pipes 300 through the branch pipe 302. Multiple air jet pipes 300 are provided. By utilizing the branch pipe 302 and the connecting pipe 201, the blower 200 can input gas into the multiple air jet pipes 300, thereby effectively improving the gas stirring effect on the sewage.

[0026] In a preferred embodiment, mounting brackets 400 fixed to the inner wall of the regulating chamber 101 are provided at both ends of the branch pipe 302 and at the end of the air jet pipe 300 away from the branch pipe 302. The mounting brackets 400 are used to lock and secure the branch pipe 302 and the air jet pipe 300 at the bottom inner side of the regulating chamber 101. The mounting brackets 400 secure the branch pipe 302 and the air jet pipe 300 within the regulating chamber 101, thereby ensuring their stability during the jet stirring process and preventing pipe shaking or loosening due to liquid sloshing and air pressure, which could affect the performance.

[0027] The fixing plate 403 is fixed to the fixing plate 401 by the fixing means 410 of the fixing plate 402. The fixing plate 403 is fixed to the fixing plate 403 by the fixing means 410 of the fixing plate 402. The locking mechanism is used to lock the arc plate 403 in the guide groove 408 so that the arc plate 403 can be firmly fixed to the outer wall of the pipe by placing the branch pipe 302 or the air jet pipe 300 in the positioning groove 402 of the corresponding seat body 401 and then manually moving the arc plate 403 along the guide groove 408. The arc plate 403 and the positioning groove 402 can be matched to form a circular ring structure to limit the outer wall of the pipe. The locking mechanism is then used to lock one end of the arc plate 403 and the end position of the positioning groove 402 so that the arc plate 403 can remain firmly fixed to the outer wall of the pipe. When disassembling, it is only necessary to unlock the locking mechanism, which makes the disassembly and assembly of the branch pipe 302 and the air jet pipe 300 convenient and efficient, and convenient for later disassembly and assembly, maintenance, inspection or replacement.

[0028] In some embodiments, the locking mechanism includes a wedge block 2 410 movably connected to the top of the inner wall on one side of the guide groove 408, and one end of the wedge block 2 410 is fixedly connected to a pull rod 411. The end of the pull rod 411 extends to the outside of the base body 401, and the outside of the pull rod 411 is provided with a reset spring 412 for automatically resetting the wedge block 2 410. The end of the arc plate 403 away from the wedge block 2 410 is fixedly connected to the wedge block 1 406. After the arc plate 403 flips 180°, the wedge block 2 410 at its end squeezes the wedge block 1 406 and moves to its lower position. The wedge block 1 406 is then reset by the reset spring 412. The elastic thrust automatically resets and limits the return direction of the wedge block 410. Combined with the limiting effect of the slide bar 407 caused by the disconnection of one end of the slide groove 409, the arc plate 403 can maintain a stable position after flipping 180°, thereby achieving stable limitation of the outer wall of the pipe; an auxiliary slot 404 connected to the guide slot 408 is provided on the top of the side of the seat body 401 away from the pull rod 411, and a toggle plate 405 fixed to the side wall of the arc plate 403 is provided in the auxiliary slot 404. The auxiliary slot 404 cooperates with the toggle plate 405, which can facilitate the operator to manually drive the arc plate 403 to move, thereby improving the convenience of operation.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
