Description

Technical Field

[0001] This utility model relates to the field of aluminum chloride waste residue recycling technology, specifically, to a high-efficiency recycling device for polyaluminum chloride waste residue. Background Technology

[0002] Polyaluminum chloride is an inorganic substance that is commonly used as a water purification material due to its adsorption, coagulation, and precipitation properties. It also has advantages such as wide applicability to various water bodies, fast hydrolysis speed, and strong adsorption capacity. Nowadays, it is also widely used as a water purification material for tap water.

[0003] However, in the production of polyaluminum chloride, the thorough mixing and reaction of raw materials will generate solid waste residue inside the reactor. This solid waste residue will settle and adhere to the inner wall of the reactor, forming scale. This brings considerable difficulty to the subsequent cleaning of the reactor. Workers need to use long-handled shovels to scrape off the scale residue from the inner wall of the reactor and then use high-pressure water guns to clean it. However, this method not only increases the labor intensity of the workers, but also increases production costs and wastes resources because the scale residue can be processed and reused after recycling. Therefore, a high-efficiency polyaluminum chloride waste residue recycling device is needed to solve the above problems. Utility Model Content

Workers need to use a long-handled shovel to scrape off the waste residue scale on the inner wall of the reactor and then use a high-pressure water gun to wash it clean. However, this method not only increases the labor intensity of the workers, but also increases the production cost and wastes resources because the waste residue scale can be processed and reused after recycling.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a high-efficiency recycling device for polyaluminum chloride waste residue, including a reactor 1. A top cover 101 is installed at the top of the reactor 1, and a feed pipe 102 is fixedly connected to the top of the top cover 101. A discharge valve pipe 103 is fixedly connected to the bottom of the reactor 1, and a filter screen 105 is threadedly connected to the bottom of the discharge valve pipe 103. A bracket 104 is fixedly connected to the outer end of the reactor 1. A stirring assembly 2 is provided between the top of the top cover 101 and the interior of the reactor 1. Several rebound components 3 are provided on the side of the stirring assembly 2, and scraping components 4 for cleaning the inner wall of the reactor 1 are provided between the side ends of the rebound components 3. The coordinated arrangement of the rebound component 3 and the scraping component 4 facilitates the scraping and cleaning of solid waste residue on the inner wall of the reactor 1. After the reaction is completed, the discharge valve pipe 103 is opened, and the liquid and waste residue are filtered through the filter screen 105. After the liquid flows out of the discharge valve pipe 103, the waste residue is intercepted at the top of the filter screen 105 and collected. At this time, the filter screen 105 can be removed from the bottom of the discharge valve pipe 103 by rotating it, and the solid waste residue after the reaction can be recycled and reused. Therefore, the difficulty of cleaning the reactor 1 is reduced, the labor intensity of the staff is reduced, and the waste residue can be recycled and reused, avoiding direct disposal, increasing production costs and wasting resources.

[0021] As one implementation method in this embodiment, such as Figure 3As shown, the stirring assembly 2 includes a motor 201, which is fixedly installed on the top of the top cover 101. A stirring rod 202 is installed at the output end of the motor 201 and inserted into the bottom of the top cover 101. Several stirring plates 203 are fixedly connected to the side end of the stirring rod 202. A connecting plate 204 is fixedly connected between the side ends of the stirring plates 203. Several rebound components 3 are all set on the side end of the connecting plate 204. In practice, by starting the motor 201, the stirring rod 202 and the stirring plates 203 are driven to rotate. The stirring plates 203 can stir the aluminum chloride and reaction solution in the reactor 1, accelerate the reaction between the two, and efficiently and quickly precipitate the waste residue.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the rebound assembly 3 includes a straight plate 301, with a screw 302 fixedly connected to the side end of the straight plate 301, and a round rod 304 fixedly connected to the side end of the straight plate 301. The round rod 304 is inserted into the side end of the connecting plate 204, and a limiting plate 305 is fixedly connected to the outer end of the round rod 304. A spring 306 is sleeved on the outer end of the round rod 304, with one end of the spring 306 fixedly connected to the side end of the straight plate 301 and the other end of the spring 306 fixedly connected to the side end of the connecting plate 204. Two sets of limiting rods 303 are fixedly connected to the side end of the straight plate 301, and both sets of limiting rods 303 are inserted into the side end of the connecting plate 204. The scraping assembly 4 includes a scraper 401, with several round openings 402 on the side end of the scraper 401. The round openings 402 facilitate the dispersion of liquid and accelerate the reaction between aluminum chloride and the reaction solution. Several openings are also provided on the side end of the scraper 401 away from the round openings 402. Each socket 403 and scraper 401 has a rotatable sleeve 404 near its side. The sleeve 404 is threadedly connected to the screw 302. The side of the screw 302 is inserted into the socket 403. During operation, as the stirring rod 202 rotates, the stirring plate 203 drives the connecting plate 204 and the scraper 401 to scrape and clean the inner wall of the reactor 1. While the scraper 401 scrapes along the inner wall of the reactor 1, the spring 306 always applies a pushing force to the scraper 401 towards the inner wall of the reactor 1, so that the scraper 401 can always be tightly attached to the inner wall of the reactor 1, which is convenient for cleaning the solid waste residue on the inner wall of the reactor 1. Afterwards, by opening the top cover 101 and taking out the stirring assembly 2 as a whole, the two sleeves 404 are rotated at the same time to disengage from the two screws 302, which makes it easy to disassemble and replace the scraper 401.

[0023] Working Principle: During the production of polyaluminum chloride, the motor 201 drives the stirring rod 202 and stirring plate 203 to rotate. The stirring plate 203 agitates the aluminum chloride and reaction solution in the reactor 1, accelerating the reaction and efficiently and quickly precipitating waste residue. At this time, the scraper 401 can scrape and clean the inner wall of the reactor 1. While the scraper 401 scrapes along the inner wall of the reactor 1, the spring 306 constantly applies a pushing force to the scraper 401 towards the inner wall of the reactor 1, so that the scraper 401 can always be tightly attached to the inner wall of the reactor 1, facilitating the cleaning of the reactor 1. The solid waste residue on the inner wall is cleaned. After the reaction is completed, the discharge valve 103 is opened. At this time, the liquid and waste residue are filtered through the filter screen 105. After the liquid flows out of the discharge valve 103, the waste residue is intercepted at the top of the filter screen 105 and collected. At this time, the filter screen 105 can be removed from the bottom of the discharge valve 103 by rotating the filter screen 105, so that the solid waste residue after the reaction can be recycled and reused. Therefore, the difficulty of cleaning the reaction vessel 1 is reduced, the labor intensity of the staff is reduced, and the waste residue can be recycled and reused, avoiding direct disposal, increasing production costs and wasting resources.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
