Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to an automated and efficient reaction device for polyaluminum chloride. Background Technology

[0002] According to Chinese Publication No. CN221693668U, an automated and efficient reaction device for polyaluminum chloride includes a reaction tank and a heating layer. A flow guide ring and a stirring mechanism are fixedly connected inside the reaction tank and fixedly connected to the top of the reaction tank. The interaction between the reaction tank, heating layer, flow guide ring, stirring mechanism, anti-settling mechanism, pressure relief mechanism, internal gear ring, feed pipe, discharge pipe, and support frame realizes an automated and efficient reaction device for polyaluminum chloride. The rotating stirring motor drives the stirring shaft to rotate, which in turn drives the inclined gear to rotate via the internal gear ring. The adjusting gear drives the conversion gear to rotate, thereby rotating the mounting plate. The plowshare simultaneously scoops up the sediment at the bottom of the reaction tank, thus stirring the mixture, improving reaction efficiency, and preventing material sedimentation that could lead to excessive pressure on the stirring motor.

[0003] In the use of the above-mentioned and existing technologies, because the raw material of polyaluminum chloride is in powder form, it will stick to the inner wall of the reactor during stirring. The existing cleaning method usually involves installing a scraper on the stirring shaft, and the rotating stirring shaft drives the scraper to scrape and clean the inner wall of the reactor. However, this method can only scrape and clean reactors without baffles. The above-mentioned and existing technologies cannot scrape and clean reactors with baffles using a scraper. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively clean reactors with baffles by scraping with a scraper, and to propose an automated and efficient polyaluminum chloride reaction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated and efficient polyaluminum chloride reaction device, comprising a reaction vessel, a vessel cover at the top of the reaction vessel, two feed inlets on the top surface of the vessel cover, a DC motor between the two feed inlets, six baffles inside the reaction vessel, a main shaft inside the reaction vessel, six stirring shafts at the bottom of the main shaft, mounting brackets on both sides of the main shaft, scrapers inside the two mounting brackets, sleeves on the surface of the two mounting brackets near the main shaft, return springs inside the six sleeves, guide rods on the surface of the two scrapers near the main shaft, screws on one side of the six guide rods, and a discharge port on the bottom surface of the reaction vessel.

[0006] Preferably, the vessel cover is connected to the reactor flange, the two feed inlets are integrally formed with the vessel cover, and the discharge port is integrally formed with the reactor.

[0007] Preferably, the DC motor is bolted to the vessel lid, the two stirring shafts are vertically arranged at equal intervals, and the main shaft passes through the six stirring shafts. The two stirring shafts are integrally formed with the main shaft, one end of the main shaft passes through the top surface of the vessel lid, and the main shaft is shaft-connected to the DC motor.

[0008] Preferably, the two baffles are equally spaced and arranged around the inner wall of the reactor, and both baffles are welded to the reactor.

[0009] Preferably, the two mounting brackets are installed on both sides of the six stirring shafts and are bolted to the stirring shafts. The three sleeves of the two mounting brackets are equally spaced and vertically erected on the surface of the mounting brackets, and the sleeves are integrally formed with the mounting brackets. All six return springs are installed in the sleeves.

[0010] Preferably, both scrapers are installed in the mounting bracket, and the positions of the three guide rods on the surface of the two scrapers correspond one-to-one with the positions of the sleeves, and the guide rods are all installed in the sleeves.

[0011] Preferably, the positions of the six screws correspond one-to-one with the positions of the guide rods, and all screws pass through the guide rods.

[0012] Beneficial effects

[0013] In this invention, a rotating stirring shaft drives scrapers in the mounting brackets on both sides to clean the interior of the reactor. When the scraper reaches the baffle plate, it squeezes the scraper and pushes it into the mounting bracket. When the scraper passes the baffle plate, it loses the pressure and is pushed out of the mounting bracket by the return spring in the sleeve. This causes the scraper to press against the inner wall of the reactor again, and the rotating stirring shaft drives the scraper to clean the inner wall of the reactor again. This solves the problem of not being able to clean reactors with baffle plates by scraping. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-6An automated and efficient polyaluminum chloride reaction device includes a reactor 1, a reactor lid 2 on top of the reactor 1, two feed inlets 3 on the top surface of the reactor lid 2, a DC motor 4 between the two feed inlets 3, six baffles 5 inside the reactor 1, a main shaft 6 inside the reactor 1, six stirring shafts 7 at the bottom of the main shaft 6, mounting brackets 8 on both sides of the main shaft 6, scrapers 10 inside the two mounting brackets 8, sleeves 9 on the surface of the two mounting brackets 8 near the main shaft 6, return springs 12 inside the six sleeves 9, guide rods 11 on the surface of the two scrapers 10 near the main shaft 6, and screws 14 on one side of the six guide rods 11, a discharge port 13 on the bottom surface of the reactor 1, a reactor lid 2 connected to a flange of the reactor 1, two feed inlets 3 integrally formed with the reactor lid 2, a discharge port 13 integrally formed with the reactor 1, a DC motor 4 bolted to the reactor lid 2, and six... The stirring shafts 7 are vertically arranged at equal intervals, and the main shaft 6 passes through the six stirring shafts 7. The six stirring shafts 7 are integrally formed with the main shaft 6. One end of the main shaft 6 passes through the top surface of the vessel cover 2 and is shaft-connected to the DC motor 4. Six baffles 5 are equally spaced around the inner wall of the reactor 1 and are welded to the reactor 1. Two mounting brackets 8 are installed on both sides of the six stirring shafts 7 and are bolted to the stirring shafts 7. Three sleeves 9 of the two mounting brackets 8 are vertically arranged at equal intervals on the surface of the mounting brackets 8 and are integrally formed with the mounting brackets 8. Six return springs 12 are installed in the sleeves 9. Two scrapers 10 are installed in the mounting brackets 8. The positions of the three guide rods 11 on the surface of the two scrapers 10 correspond one-to-one with the positions of the sleeves 9 and are all installed in the sleeves 9. The positions of the six screws 14 correspond one-to-one with the positions of the guide rods 11 and are all through the guide rods 11.

[0026] The vessel cover 2 is connected to the flange of the reactor 1, sealing the internal space of the reactor 1. Two feed inlets 3 are integrally formed with the vessel cover 2, allowing the raw materials for producing polyaluminum chloride to enter the reactor 1 through the feed inlets 3. The discharge port 13 is located in the middle of the top surface of the reactor 1 and is integrally formed with the reactor 1. After the raw materials inside the reactor 1 have reacted to produce polyaluminum chloride, the valve of the discharge port 13 can be opened, and the material inside the reactor 1 can be discharged through the discharge port 13. The DC motor 4 is installed in the middle of the top surface of the vessel cover 2 by six fixing bolts, and one end of the main shaft 6 extends through the vessel. The top surface of the cover 2 is connected to the DC motor 4 shaft, and six stirring shafts 7 are set on the main shaft 6. When the material enters the interior of the reactor 1, the DC motor 4 is turned on by the control system, so that the DC motor 4 drives the main shaft 6 to rotate. When the main shaft 6 rotates, the stirring shafts 7 integrally formed with the main shaft 6 will also rotate. The rotating stirring shafts 7 stir the raw materials inside the reactor 1, thereby increasing the reaction efficiency. Six baffles 5 are equally spaced around the inner wall of the reactor 1. The baffles 5 will disrupt the laminar flow generated by the material during the stirring and mixing of the stirring shafts 7, so that the material generates turbulence. The characteristic of turbulence is the irregular movement of fluid micro-particles in all directions. This movement greatly increases the probability of collision and mixing between different materials, improving the efficiency of material mixing. Thus, through the efficiency of the reactor 1, two mounting brackets 8 are respectively installed on both sides of the six stirring shafts 7, and each mounting bracket 8 is fixed with six fixing bolts. Three sleeves 9 on the surface of the two mounting brackets 8 are used to install return springs 12 and guide rods 11. The sleeves 9 restrict the rebound direction of the return springs 12 and guide the guide rods 11. Two scrapers 10 are installed in the mounting brackets 8. The scrapers 10 scrape and clean the material on the inner wall of the reactor 1. The three guide rods 11 on the surface of the scrapers 10 are installed in the sleeves 9 and abut against the return springs 12 inside the sleeves 9. Six screws 14 are also screwed on the six guide rods 11, so that when the return springs 12 squeeze the scrapers 10 out of the mounting brackets 8, the screws 14 installed on the guide rods 11 will lock the mounting brackets 8, thus preventing the scrapers 10 from being pushed out by the return springs 12.

[0027] During use, the vessel lid 2 is connected to the reactor 1 via a flange, sealing the internal space of the reactor 1 and ensuring the reaction takes place in a relatively closed environment. Furthermore, the feed inlet 3 is integrally formed with the vessel lid 2. When polyaluminum chloride production is required, raw materials can smoothly enter the reactor 1 through the feed inlet 3, providing materials for the reaction. Once the materials enter the reactor 1, the control system starts the DC motor 4, which drives the main shaft 6 to rotate. Since the stirring shaft 7 is integrally formed with the main shaft 6, the stirring shaft 7 also rotates. The rotating stirring shaft 7 stirs the raw materials inside the reactor 1, making the mixture more uniform and increasing the contact opportunities between reactants, thereby improving reaction efficiency. While the stirring shaft 7 is stirring the materials, the baffle 5 disrupts the laminar flow generated during the rotation. Because in laminar flow, the materials mainly flow in layers parallel to the flow direction, with relatively little exchange of substances between different layers. The baffle 5 creates turbulence in the material, and the turbulent fluid particles move irregularly in all directions, greatly increasing the probability of collision and mixing between different materials, further improving the material mixing efficiency, and thus enhancing the working efficiency of the reactor 1. Two scrapers 10 are installed in the mounting frame 8, and three guide rods 11 on their surface are installed in the sleeve 9, abutting against the return spring 12 inside the sleeve 9. Under normal conditions, the scrapers 10 maintain a certain position within the mounting frame 8. When the stirring shaft 7 rotates, driving the mounting frame 8 and scrapers 10 to move, the scrapers 10 will contact the inner wall of the reactor 1. If there is material adhering to the inner wall, the scrapers 10 will scrape it off. Six screws 14 are screwed onto the guide rods 11. When the return spring 12 tends to squeeze the scrapers 10 out of the mounting frame 8 for some reason (such as the scrapers 10 rebounding after being subjected to large inward pressure), the screws 14 will lock the mounting frame 8 to prevent the scrapers 10 from being excessively squeezed out. This ensures that the scraper 10 always operates within a reasonable range, effectively scraping away material from the inner wall of the reactor 1 without excessive extension that could interfere with the normal stirring and reaction process within the reactor 1. The raw materials undergo a series of chemical reactions to produce polyaluminum chloride. Once the reaction is complete, the valve at the discharge port 13 is opened manually or through an automated control system. At this point, the material inside the reactor 1 flows out of the reactor 1 through the discharge port 13 under gravity, entering the subsequent processing steps. Specific Implementation Example 2:

[0029] Reference Figure 1-6An automated and efficient polyaluminum chloride reaction device is further based on the basic structure in Specific Embodiment 1. The six sleeves 9 are provided with through holes on the side near the main shaft 6, and each through hole is provided with a side cover 15. The side cover 15 is installed and fixed by four fixing bolts. When the return spring 12 inside the sleeve 9 is damaged during long-term use, the fixing bolts of the side cover 15 of the sleeve 9 where the damaged return spring 12 is located can be directly removed, and a new return spring 12 can be installed into the sleeve 9. After installation, the side cover 15 is installed on the sleeve 15 again by fixing bolts to complete the replacement of the damaged return spring 12. Thus, it is not necessary to disassemble the entire mounting frame 8, which facilitates subsequent maintenance.

[0030] In summary:

[0031] 1. A rotating stirring shaft drives scrapers in the mounting brackets on both sides to clean the interior of the reactor. When the scraper reaches the baffle plate, the baffle plate squeezes the scraper and pushes it into the mounting bracket. When the scraper passes the baffle plate, it loses the pressure of the baffle plate and is pushed out of the mounting bracket by the return spring in the sleeve. This causes the scraper to press against the inner wall of the reactor again, and the rotating stirring shaft drives the scraper to clean the inner wall of the reactor again. This solves the problem of not being able to clean reactors with baffle plates by scraping.
