Technical Field

[0001] This utility model relates to the field of neutralization kettles, specifically to a neutralization kettle with a filtration mechanism. Background Technology

[0002] A neutralization reactor is a stirred tank reactor used for neutralization reactions to achieve the purpose of neutralization. Neutralization reactors are widely used in industries such as chemical, pharmaceutical, electroplating, and wastewater treatment to ensure the safety and efficiency of the reaction.

[0003] Currently, neutralization kettles generally do not have the function of filtering materials, which leads to the problem of material residue adhering to the inner wall surface after long-term use. In addition, existing neutralization kettles usually use a motor-driven stirring rod for simple stirring, which is not effective and detrimental to neutralization efficiency, and further improvements are needed.

[0004] Therefore, it is necessary to invent a neutralization vessel with a filtration mechanism. Utility Model Content

[0005] Therefore, this utility model provides a neutralization vessel with a filtration mechanism to solve the problems mentioned in the background art.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-4 The present invention provides a neutralization vessel with a filtration mechanism, comprising a vessel body 1, a support 2 fixed at the bottom of the vessel body 1, feed pipes 3 symmetrically fixed and connected to both sides of the top of the vessel body 1, a discharge pipe 4 fixedly connected to the center of the bottom of the vessel body 1, a discharge valve 5 fixedly fixed to the body of the discharge pipe 4, a filtration assembly detachably installed at the top of the feed pipe 3, and a stirring assembly installed at the top of the vessel body 1 via a lifting assembly.

[0023] The filtration assembly includes two filter tanks 6, with flanges at the bottom of each filter tank 6 connected to the top of two feed pipes 3. Each filter tank 6 has a fixed filter screen 7 inside, and each filter tank 6 has a flange connected to a feed inlet 8. It should be noted that the filter screen 7 is preferably made of polytetrafluoroethylene (PTFE), which has excellent acid and alkali corrosion resistance and high temperature resistance. Specifically, the material can enter the filter tank 6 through the feed inlet 8, where impurities are effectively filtered out by the filter screen 7, and then enter the vessel body 1 through the feed pipe 3 for neutralization. The filter tank 6 is flanged with the feed pipe 3 and the feed inlet 8, which facilitates disassembly and replacement.

[0024] The lifting assembly includes a vertically arranged electric push rod 9, the bottom end of which is fixed to the top of the vessel body 1. A lifting plate 10 is fixed to the top of the output shaft of the electric push rod 9. Support rods 11 are vertically fixed at the top corners of the lifting plate 10. A top plate 12 is horizontally fixed to the top of the support rods 11. Specifically, when the electric push rod 9 is running, it can drive the lifting plate 10 to move up and down, thereby driving the top plate 12 to move up and down synchronously through the support rods 11.

[0025] The stirring assembly includes a reducer 13, which is a transmission device used for low-speed, high-torque operation. It reduces the speed of the high-speed motor by meshing a small gear on the input shaft with a large gear on the output shaft. The top of the reducer 13 is fixed to the center of the bottom of the top plate 12. A servo motor 14 is vertically fixed to the center of the top of the top plate 12. The output shaft of the servo motor 14 vertically penetrates the top plate 12 and is fixedly connected to the input shaft of the reducer 13. A connecting shaft 15 is vertically fixed to the bottom of the output shaft of the reducer 13. The bottom of the connecting shaft 15 passes through the lifting plate 10 and the top of the vessel body 1. A first stirring paddle 16 is fixed, and the surface of the connecting shaft 15 is rotatably connected to the lifting plate 10. The connecting shaft 15 and the lifting plate 10 are preferably rotatably connected by bearings. That is, under the action of the lifting plate 10, the stability of the rotation of the connecting shaft 15 can be increased. Specifically, under the deceleration action of the reducer 13, when the servo motor 14 is running, the first stirring paddle 16 can be driven to rotate slowly in the vessel body 1 through the connecting shaft 15, thereby stirring and neutralizing the material entering the vessel body 1. When the electric push rod 9 moves to drive the lifting plate 10 and the top plate 12 to rise and fall, it can drive the rotating first stirring paddle 16 to rise and fall synchronously in the vessel body 1.

[0026] A rotating shaft 17 is symmetrically connected to both sides of the bottom of the top plate 12. The bottom end of the rotating shaft 17 passes through the lifting plate 10 and the top of the vessel body 1. A second stirring paddle 18 is fixed to the bottom end of each rotating shaft 17. The surface of the rotating shaft 17 is rotatably connected to the lifting plate 10. The rotating shaft 17 and the lifting plate 10 are preferably rotatably connected by bearings, which increases the stability of the rotation of the rotating shaft 17 under the action of the lifting plate 10. A driving synchronous pulley 19 is fixed from top to bottom on the surface of the connecting shaft 15. A driven synchronous pulley 20 is fixed on the surface of the rotating shaft 17. The two driving synchronous pulleys 19 and the two driven synchronous pulleys 20 are respectively one-to-one. The driving synchronous pulleys 19 and the corresponding driven synchronous pulleys 20 are connected to each other. All wheels 20 are connected by a synchronous belt 21. Specifically, when the servo motor 14 drives the first stirring paddle 16 to rotate via the connecting shaft 15, it can drive the active synchronous belt pulley 19 to rotate together. This, in turn, drives the corresponding driven synchronous belt pulley 20 to rotate synchronously via the synchronous belt 21, which in turn drives the corresponding rotating shaft 17 to rotate synchronously. This allows the second stirring paddle 18 to rotate together inside the vessel 1. Thus, the first stirring paddle 16 and the second stirring paddle 18 rotate together inside the vessel 1. Furthermore, under the action of the electric push rod 9, the first stirring paddle 16 and the second stirring paddle 18 can also move up and down together inside the vessel 1, thereby effectively improving the stirring effect on the material and thus contributing to the neutralization efficiency.

[0027] It should be noted that this utility model is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device such as a computer for control.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
