[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1The chemical reagent wastewater treatment device in this embodiment includes a filter box 1. The top of the filter box 1 is provided with a pressurizing mechanism 2 that can filter and pressurize the wastewater. A water pipe 3 is fixedly connected to the right side of the filter box 1. A reaction box 4 is fixedly connected to the side of the water pipe 3 away from the filter box 1. A stirring mechanism 5 that can mix the wastewater and the reagent is provided on the top of the reaction box 4. A gas injection component 6 that continuously supplies gas is provided on the left side of the reaction box 4.

[0024] In addition, the pressurizing mechanism 2 includes a cover plate 201 that abuts against the top of the filter box 1. The top of the filter box 1 is open, and the cover plate 201 extends outside the filter box 1. The bottom of the cover plate 201 is provided with two stabilizing parts 202 located on the left and right sides of the filter box 1, respectively. The top of the cover plate 201 is fixedly connected to a water inlet pipe 203, which facilitates the entry of chemical reagent wastewater into the filter box 1. The top of the cover plate 201 is fixedly provided with a drive motor 204. One end of the output shaft of the drive motor 204 is fixedly provided with a threaded rod 205 that penetrates the cover plate 201. The outer surface of the threaded rod 205 is threadedly connected to a threaded sleeve 206. The inner side of the filter box 1 is fixed with two limiting rods, both of which penetrate the filter part 207. The outer surface of the threaded sleeve 206 and the filter part 207 located inside the filter box 1 are provided with the filter part 207.

[0025] It should be further explained that each stabilizing part 202 includes an extension rod 2021 fixed to the bottom of the cover plate 201. The extension rod 2021 is limited by the fixing block 2022, and further limited by the connecting bolt 2023, thereby ensuring that the extension rod 2021 cannot move. This indirectly ensures the stability of the cover plate 201. Fixing blocks 2022 are fixed on both the left and right sides of the filter box 1. The two extension rods 2021 pass through the two fixing blocks 2022 respectively. Each fixing block 2022 has a connecting bolt 2023 threaded on the side away from the filter box 1 that passes through the extension rod 2021. When it is necessary to open the cover plate 201, it is only necessary to unscrew the two connecting bolts 2023.

[0026] It is known that the filter section 207 includes a filter plate 2071 fixed to the outer surface of the threaded sleeve 206. The filter plate 2071 has multiple stepped holes, which help the wastewater flow. A connecting spring 2072 is fixed on the inner wall of each stepped hole. The connecting spring 2072 plays a connecting role to ensure that the barrier plate 2073 will not completely detach from the filter plate 2071. The other end of the connecting spring 2072 is fixed to the barrier plate 2073.

[0027] In this embodiment, when the filter plate 2071 moves upward, the water will push the barrier plate 2073 aside and then fall into the filter box 1 under the action of gravity. When the filter plate 2071 moves downward, the barrier plate 2073 will abut against the stepped hole, and at this time the water will be squeezed into the reaction box 4.

[0028] Please refer to it again. Figures 1 to 3 To improve processing efficiency, the stirring mechanism 5 in this embodiment includes a servo motor 501 fixed to the top of the reaction tank 4. One end of the output shaft of the servo motor 501 is fixed with a drive rod 502. The servo motor 501 is used to provide power to the drive rod 502. The bottom of the drive rod 502 is rotatably connected to the top of the reaction tank 4 through a bearing. A drive gear 503 is fixed to the outer surface of the drive rod 502. A driven gear 504 meshes with the left side of the drive gear 503. The drive gear 503 and the driven gear 504 cooperate to transmit power. A stirring shaft 505 penetrating the top wall of the reaction tank 4 is fixed to the inner side of the driven gear 504. Multiple stirring blades 506 are fixed to the outer surface of the stirring shaft 505.

[0029] In addition, an air jet pipe 507 is fixedly connected to the outside of the stirring shaft 505 and below multiple stirring blades 506. The air jet pipe 507, together with the one-way valve 508, can ensure that the gas of the air injection component 6 is smoothly injected into the water. Each air jet pipe 507 is equipped with a one-way valve 508.

[0030] In addition, a connecting platform is fixed on the left side of the reaction chamber 4, and a rib is fixed at the bottom of the connecting platform. The rib is fixed to the side wall of the reaction chamber 4. The rib is used to improve the stability of the connecting platform. The gas injection assembly 6 includes an air pump 601 fixed to the top of the connecting platform. The air inlet end of the air pump 601 is fixedly connected to a gas supply device, which can be an oxygen cylinder, as long as it meets the usage requirements. The output end of the air pump 601 is fixedly connected to a gas injection pipe 602. The gas injection pipe 602 extends into the stirring shaft 505 and is rotatably connected to the stirring shaft 505 through a bearing.

[0031] Furthermore, a dosing pipe is fixedly connected to the top of the reaction chamber 4, an exhaust pipe is fixedly connected to the right side of the reaction chamber 4, and a collection box is fixedly connected to the other end of the exhaust pipe. The collection box is used to collect gas. A drain pipe is fixedly connected to the right side of the reaction chamber 4 and below the exhaust pipe. A solenoid valve is installed on the drain pipe. When the solenoid valve is opened, the liquid can be discharged.

[0032] In this embodiment, since the stirring shaft 505 will rotate under the action of the driven gear 504, the gas injection pipe 602 needs to be connected to the stirring shaft 505 through the bearing, and the stirring shaft 505 is rotatably connected to the top wall of the reaction chamber 4 through the bearing.

[0033] It is understandable that by combining the pressurizing mechanism 2, the stirring mechanism 5, and the air injection component 6, the processing efficiency can be effectively improved, and it is also convenient to clean large particulate impurities on the filter plate 2071.

[0034] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0035] The working principle of the above embodiments is as follows:

[0036] In operation, wastewater is first discharged into the filter box 1 through the inlet pipe 203, at which point the filter section 207 is at the bottom. Then, the drive motor 204 is started, driving the threaded rod 205 to rotate. Due to the threaded connection between the threaded rod 205 and the threaded sleeve 206, the threaded sleeve 206 will move the filter section 207 upwards together. Due to gravity, the wastewater will flow through the filter plate 2071, and large particles of impurities will be blocked by the filter plate 2071. Then, the drive motor 204 is started in reverse, causing the filter plate 2071 to descend. Due to the blocking effect of the blocking plate 2073, the waste liquid will be forced into the reaction tank 4. Then, the chemical agents required for treatment are added to the reaction tank 4, and the servo motor 501 is started. The power of the servo motor 501, through the driving gear 503 and the driven gear 504, causes the stirring blades 506 on the stirring shaft 505 to rotate, thereby stirring the water and treating the wastewater. After the reaction is completed, the solenoid valve is opened to discharge the water into the subsequent device.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
