Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride water purification agent production technology, and in particular to a polyaluminum chloride water purification agent slurry preparation reactor. Background Technology

[0002] In a broad sense, a reaction vessel is a container used for physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Polyaluminum chloride (PAC) is a chemical product, and the reaction vessel is a commonly used piece of equipment in the production of PAC. During production, various raw materials are added to the reaction vessel for heating and stirring. At the same time, the top of the reaction vessel is reserved to allow the raw materials to move and the generated gases to remain. However, since the boiling points of various raw materials are different during the heating process, some raw materials will volatilize to the top wall of the reaction vessel without reacting with other raw materials. This reduces the accuracy of the raw material mixing ratio and lowers the quality of the product.

[0003] In the prior art, application number CN202322423826.6 proposes a polyaluminum chloride water purification agent slurry preparation reactor. When the polyaluminum chloride water purification agent production is completed and the reactor body needs to be cleaned, a cleaning motor starts working. The output end of the cleaning motor drives the rotating shaft, which in turn drives the cleaning rod. The cleaning rod then agitates and cleans the residual polyaluminum chloride water purification agent in the reactor body. Clean water is then poured in through the inlet, and the outlet is opened to discharge the polyaluminum chloride water purification agent residue from the reactor body, thus completing the cleaning process. This solves the problem in the prior art where adding a clearance component, while effectively improving product quality, makes subsequent cleaning difficult due to the obstruction of the clearance component.

[0004] However, in the process of using the above-mentioned patent, the water flow is used to clean the polyaluminum chloride water purification agent residue on the inner wall of the reactor. However, the polyaluminum chloride water purification agent residue that is more firmly attached cannot be removed by the above method. Based on the above problems, this application proposes a polyaluminum chloride water purification agent slurry preparation reactor. Utility Model Content

[0016] 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.

[0017] Example: Refer to Figure 1-5A polyaluminum chloride water purification agent slurry preparation reactor includes a reactor body 1, a reactor cover 2 fixedly mounted on the top of the reactor body 1, a rotating assembly at the bottom of the reactor body 1, a hollow stirring shaft 12 rotatably mounted inside the reactor body 1, a hollow stirring rod 13 fixedly mounted on the surface of the hollow stirring shaft 12, a rotary joint 14 installed at the liquid inlet end of the hollow stirring rod 13, a water inlet pipe 15 installed at the liquid inlet end of the rotary joint 14, a sealing assembly at the end of the hollow stirring rod 13, and a clearance assembly at the bottom of the reactor cover 2. The rotating assembly includes a fixing frame 5 fixedly mounted at the bottom of the reactor body 1, and the water inlet pipe 15 is connected to the fixing frame 5. The system is fixedly connected, with a motor bracket 6 fixedly mounted at the bottom of the fixed frame 5, and a stirring motor 7 fixedly mounted at the bottom of the motor bracket 6. A coupling is fixedly mounted at the output end of the stirring motor 7, and a rotating shaft 8 is mounted on the output end of the stirring motor 7 via the coupling. A fixed seat 9 is mounted on the top of the rotating shaft 8 via a bearing, and the fixed seat 9 is fixedly mounted on the bottom of the vessel body 1. A driving gear 10 is fixedly mounted on the surface of the rotating shaft 8, and a driven gear 11 meshes with the surface of the driving gear 10. The driven gear 11 is fixedly mounted on the surface of the hollow stirring shaft 12. There are several hollow stirring rods 13. Several hollow stirring rods 13 are arranged in a circular array. The hollow stirring rods 13 are connected to the hollow stirring shaft 12. The stirring motor 7 drives the coupling to rotate the rotating shaft 8. The rotating shaft 8 drives the hollow stirring shaft 12 to rotate through the driving gear 10 and the driven gear 11. The hollow stirring shaft 12 then drives the hollow stirring rods 13 to rotate, thus stirring the raw materials. When it is necessary to clean the inside of the vessel 1, the external conveying equipment delivers water to the inside of the water inlet pipe 15 through a pipeline, and then enters the hollow stirring shaft 12 through the rotary joint 14. The water is then diverted through the hollow stirring shaft 12 into the hollow stirring rod 13, causing the water to be sprayed onto the inner wall of the reactor body 1. The water flow washes away the residual aluminum chloride water purification agent on the inner wall of the reactor body 1, and the water is discharged from the reactor body 1 through the discharge pipe. Moreover, when there is too much water inside the reactor, the hollow stirring rod 13 can drive the water flow to move, so that the water flow cleans the inner wall of the reactor, thereby removing the residual polyaluminum chloride water purification agent on the inner wall of the reactor, avoiding the situation where the firmly attached polyaluminum chloride water purification agent residue cannot be removed.

[0018] Specifically, the sealing assembly includes a mounting bracket 16 fixedly installed on the surface of the hollow stirring rod 13. A mounting shaft 17 is fixedly installed inside the mounting bracket 16. A connecting plate 18 is rotatably mounted on the surface of the mounting shaft 17. A sealing plate 19 is fixedly installed at the end of the connecting plate 18. The sealing plate 19 has a circular structure, and its radius is the same as the outer diameter of the hollow stirring rod 13. A ring magnet 20 is fixedly installed inside the sealing plate 19. The ring magnet 20 attracts the hollow stirring rod 13, causing the water flow to push the sealing plate 19 to rotate. The sealing plate 19 causes the connecting plate 18 to rotate on the surface of the mounting shaft 17, causing the sealing plate 19 to separate the annular magnet 20 from the hollow stirring rod 13. When water jet is not required, the sealing plate 19 causes the connecting plate 18 to rotate on the surface of the mounting shaft 17 by its own gravity, causing the sealing plate 19 to come into contact with the hollow stirring rod 13, causing the annular magnet 20 to be attracted to the hollow stirring rod 13. This allows the sealing plate 19 to seal the hollow stirring rod 13, preventing aluminum chloride water purification agent from entering the interior of the hollow stirring rod 13.

[0019] Preferably, the clearance assembly includes a sleeve 21 fixedly installed at the bottom of the vessel lid 2. A T-shaped rod 22 is fixedly installed on the upper side wall of the sleeve 21. A central spring 23 is fixedly installed at the bottom end of the T-shaped rod 22. The central spring 23 is slidably connected to the sleeve 21. A circular plate 24 is fixedly installed at the bottom end of the central spring 23. A rectangular rod 25 is fixedly installed at the top of the circular plate 24. A U-shaped plate 26 is slidably installed on the surface of the rectangular rod 25. The U-shaped plate 26 is fixedly installed at the bottom of the vessel lid 2. An auxiliary spring connects the top of the rectangular rod 25 and the bottom of the vessel lid 2. The surface of the circular plate 24 overlaps with... A circular ring 27 is fixedly installed inside the reactor body 1. When the gas is stirred, it impacts the circular plate 24, causing it to move up and down. This causes the circular plate 24 to move the rectangular rod 25 and the central spring 23. The central spring 23 compresses the T-shaped rod 22, while the rectangular rod 25 compresses the auxiliary spring. This causes the circular plate 24 and the circular ring 27 to separate, allowing the gas to enter the upper cavity of the reactor body 1 through the channel between the circular plate 24 and the circular ring 27. This improves the accuracy of the mixing ratio of various raw materials and enhances the quality of the product.

[0020] Specifically, a feed pipe 3 is fixedly installed on the top of the vessel lid 2, and a sealing cap 4 is threaded on the surface of the feed pipe 3. A discharge pipe is fixedly installed at the bottom of the sealing cap 4, and a control valve is fixedly installed on the surface of the discharge pipe. The feed pipe 3 facilitates the addition of raw materials into the vessel body 1, and the sealing cap 4 can seal the feed pipe 3 to prevent dust from entering the vessel body 1 through the feed pipe 3. The discharge pipe facilitates the discharge of the aluminum chloride water purification agent after slurry preparation.

[0021] The polyaluminum chloride water purification agent slurry preparation reactor is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0022] In use: The raw materials required for preparing the aluminum chloride water purifier slurry are added to the interior of the reactor body 1 through the feed pipe 3. After the raw materials are added, the sealing cap 4 is tightened onto the surface of the feed pipe 3. Then, the external controller controls the stirring motor 7 to drive the coupling, which in turn drives the rotating shaft 8 to rotate. This rotating shaft 8 drives the drive gear 10 to rotate, and the drive gear 10, through its meshing driven gear 11, drives the hollow stirring shaft 12 to rotate. This causes the hollow stirring shaft 12 to drive the hollow stirring rod 13 to rotate, thus agitating the raw materials through the hollow stirring rod 13. When it is necessary to clean the inside of the vessel body 1, the external conveying equipment is connected to the water inlet pipe 15 through the pipeline. The external conveying equipment delivers water to the inside of the water inlet pipe 15 through the pipeline, and then enters the inside of the hollow stirring shaft 12 through the rotary joint 14. The water is then diverted through the hollow stirring shaft 12 into the inside of the hollow stirring rod 13, so that the water is sprayed onto the inner wall of the vessel body 1 through the hollow stirring rod 13. The water washes away the aluminum chloride water purification agent residue on the inner wall of the vessel body 1, and the water is discharged from the vessel body 1 through the discharge pipe.
