Description

Technical Field

[0001] This application relates to the field of reaction vessels, and more specifically, to a reaction vessel for preparing polyaluminum chloride using aluminum ash. Background Technology

[0002] In the preparation of polyaluminum chloride from aluminum ash, the reactor is a commonly used piece of equipment. After the raw materials are added, stirring is required, so the reactor is usually equipped with a stirring structure. However, most existing stirring structures are directly installed inside the reactor. Even after the stirring process is complete, the stirring structure remains inside the reactor and is always immersed in the raw materials. This design presents two significant problems: First, the stirring structure can chemically react with the raw materials, directly affecting the purity and performance of the polyaluminum chloride and reducing product quality. Second, the raw materials are corrosive, and long-term contact with the stirring structure will cause continuous erosion, significantly shortening the lifespan of the stirring structure and increasing equipment maintenance costs and replacement frequency. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a reactor for preparing polyaluminum chloride using aluminum ash. This reactor allows for the lowering of the rotating shaft and stirring plate into the reactor body when stirring is required, to agitate the raw materials. After stirring is completed, the rotating shaft and stirring plate are raised and stored inside a vertical tank. The bottom of the vertical tank is sealed by a pull-out end of a stopper plate, allowing for cleaning of the rotating shaft and stirring plate inside the vertical tank. This reduces corrosion of the rotating shaft and stirring plate, extends their service life, and lowers the frequency of replacement and maintenance.

[0004] A reactor for preparing polyaluminum chloride using aluminum ash according to an embodiment of this application includes: a reactor body and a stirring frame assembly. A lifting frame is provided on the outside of the reactor body. The stirring frame assembly includes a vertical barrel, a pull-out stopper, a first lifting slide rail, a rotating shaft, a push-pull frame, stirring plates, and a liquid supply pump. The pull-out stopper is located on the upper part of the reactor body. The vertical barrel is installed on the upper part of the pull-out stopper. The upper side of the vertical barrel is fixedly connected to the upper part of the lifting frame. The first lifting slide rail is located inside the vertical barrel. The lifting end of the first lifting slide rail is slidably connected to the inside of the vertical barrel. The upper part of the rotating shaft is rotatably connected to the sliding end of the first lifting slide rail. The push-pull end of the push-pull frame is slidably connected to the outside of the rotating shaft. Multiple stirring plates are arranged in an array. One side of the stirring plate is rotatably connected to the push-pull frame. The middle part of the stirring plate is slidably connected to the rotating shaft. The output end of the liquid supply pump is connected to the upper part of the vertical barrel.

[0005] According to an embodiment of this application, a reaction vessel for preparing polyaluminum chloride using aluminum ash has the following advantages: Firstly, it successfully avoids unnecessary contact between the stirring structure and the raw materials, ensuring product quality. Through the action of the first lifting slide rail, the rotating shaft and stirring plate can be accurately lowered into the vessel body when stirring is required, ensuring that the raw materials are fully stirred. After the stirring operation is completed, the rotating shaft and stirring plate can be lifted and stored in the vertical tank in a timely manner. At this time, the pull-out end of the pull-out blocking plate will seal the opening at the top of the vessel body, so that the stirring structure is completely isolated from the raw materials in the vessel body. This fundamentally eliminates the possibility of chemical reaction between the stirring structure and the raw materials during the non-stirring stage, avoids the impact on the purity and performance of polyaluminum chloride, and significantly improves the production quality of the product. On the other hand, it significantly reduces corrosion of the mixing structure, extends its service life, and lowers equipment maintenance costs. After the mixing operation is completed, the rotating shaft and mixing plate can be stored inside the vertical tank and can be specially cleaned inside the tank, reducing long-term contact with corrosive raw materials. At the same time, the relatively closed environment provided by the vertical tank further reduces the erosion of the mixing structure by external factors. This greatly reduces the degree of corrosion on the rotating shaft and mixing plate, effectively improving their service life, reducing equipment failures caused by corrosion, and reducing the frequency of replacement and maintenance of the mixing structure, thereby saving equipment maintenance and replacement costs. In addition, the design of this component enhances the flexibility and convenience of operation. The lifting and storage process of the stirring structure is completed through the coordinated operation of related components, which is simple and efficient. It not only meets the stirring requirements, but also achieves proper storage when not in operation, making the entire production process smoother and more efficient.

The first motor is fixedly connected to the upper part of the vertical barrel. The output end of the first motor is drivenly connected to the first lead screw. The first lead screw is threadedly connected to the lifting plate. The lifting plate is slidably connected to the inside of the vertical barrel.

[0011] According to this application, the first motor output end is provided with a first pulley, the first lead screw is provided with a second pulley, and the first pulley and the second pulley are connected in a driving connection.

[0012] According to this application, the rotating shaft includes a second motor and a shaft rod. The second motor is fixedly connected to the lifting plate, the upper part of the shaft rod is rotatably connected to the lifting plate, and the push-pull frame is slidably connected to the shaft rod.

[0013] According to this application, the push-pull frame includes a third frame, a third telescopic member, and a connecting plate. The third frame is slidably connected to the outer side of the shaft and rotatably connected to one side of the stirring plate. The third telescopic members are symmetrically arranged and fixedly connected to the lifting plate. The output end of the third telescopic member is fixedly connected to the upper part of the connecting plate, and the upper part of the connecting plate is slidably connected to the lifting plate. The upper part of the third frame is rotatably connected to the connecting plate.

[0014] According to this application, both the output end of the liquid supply pump and the external discharge pipe are provided with flexible hoses, and one end of each flexible hose is connected to the upper part of the vertical tank.

[0015] During the use of a reactor, raw materials or reactants often adhere to the inner wall of the reactor, requiring cleaning. However, frequently used reactors are not convenient for internal cleaning, thus causing inconvenience.

[0016] According to this application, a cleaning assembly is also included, comprising a first lifting frame, a first linear slide rail, a second lifting frame, a second linear slide rail, a third lifting frame, a rotating brush, and a third motor. A first vessel and a second vessel are disposed at the bottom of the vessel body. Both the bottom of the vessel body and the bottom of the second vessel are provided with threaded heads. Threaded sleeves are disposed at the upper parts of the first and second vessel, with the threaded heads threadedly connected to the threaded sleeves. The first lifting frame is disposed on one side of the lifting frame. The first vessel is rotatably connected to the lifting end of the first lifting frame. The bottom of the second lifting frame is fixedly connected to the upper part of the sliding end of the first linear slide rail. The second vessel is rotatably connected to the lifting end of the second lifting frame. Two third motors are provided: one third motor is fixedly connected to the lifting end of the first lifting frame, and its output end is drivenly connected to the first vessel; the other third motor is fixedly connected to the lifting end of the second lifting frame, and its output end is drivenly connected to the second vessel. The bottom of the third lifting frame is fixedly connected to the sliding end of the third linear slide rail. The rotating end of the rotating brush is rotatably connected to the lifting end of the third lifting frame. The design of this cleaning component brings many benefits. First, it addresses the problem of inconvenient internal cleaning of the reactor due to frequent use. The detachable structure design enables efficient cleaning. The first lifting frame works with the third motor to detach the first vessel from the bottom of the second vessel. The second lifting frame works with another third motor to remove the second vessel from the bottom of the reactor body. Then, the second lifting frame and the second vessel are moved by the first linear slide rail, separating the reactor body, the first vessel, and the second vessel from each other. This breaks the cleaning limitations of the traditional integrated reactor structure and creates favorable conditions for subsequent in-depth cleaning. Secondly, the flexibility and comprehensiveness of the cleaning process are greatly improved. The third lifting frame drives the rotating brush to rise and fall, and combined with the movement function of the second linear slide rail, the rotating brush can be accurately delivered to the bottom of the vessel. After the lifting frame adjusts the height of the vessel, the upper part of the rotating brush can penetrate deep into the interior of the vessel, and the lower part can be adapted to the first or second vessel, realizing the simultaneous or separate cleaning of the interior of the vessel, the first vessel, and the second vessel. At the same time, the cleaning water is accurately delivered to the interior of the vessel through the vertical tank, which, together with the rotation of the rotating brush, ensures the thoroughness of the cleaning and effectively solves the problem of raw materials or reactants adhering to the inner wall and being difficult to remove. In addition, the integrated design of the entire cleaning process and components significantly improves the ease of operation. From the disassembly of the vessel and its movement to the positioning of the rotating brush and cleaning, each step is seamlessly connected without the need for complex manual intervention. This not only saves cleaning time but also reduces the impact on subsequent production caused by incomplete manual cleaning, making the daily maintenance of the reactor more efficient and convenient.

[0017] According to this application, the first lifting frame, the second lifting frame, and the third lifting frame each include a vertical frame, a fourth motor, a slide, and a second lead screw. The fourth motor is fixedly connected to the upper part of the vertical frame.

[0018] According to this application, both the first linear slide rail and the second linear slide rail include a fifth motor, a fifth lead screw, and a first slider. The output end of the fifth motor is fixedly connected to one end of the fifth lead screw, the fifth lead screw is threadedly connected to the first slider, and the first slider is fixedly connected to the bottom of one of the uprights.

[0020] According to this application, both the first and second vessels are provided with sealing gaskets on their upper parts, both the first and second vessels are provided with gear rings, and the output end of the third motor is provided with a gear, which meshes with the gear ring.

[0021] When cleaning the reactor, cleaning water containing raw material impurities is generated. Since the amount of water used for cleaning is relatively small, investing in large-scale wastewater treatment equipment would increase the company's costs. If this cleaning water is discharged directly, it will not only waste raw materials but also pollute the environment.

[0022] According to this application, a cleaning water treatment component is also included, comprising a water receiving tank, a pump, a sedimentation tank, a lifting stop plate, a pusher frame, and a plug. The water receiving tank is located below the vessel body and is connected to the input end of the pump. The output end of the pump is connected to the top of the sedimentation tank, and the bottom of the vertical tank is connected to the top of the sedimentation tank. The lifting stop plates are symmetrically arranged, and the lifting end of the lifting stop plate is slidably connected to the sedimentation tank. The pushing end of the pusher frame is located on the bottom side inside the sedimentation tank, and the plugs are symmetrically arranged on both sides of the sedimentation tank. During operation, cleaning water is used both to clean the rotating shaft and stirring plate after they are housed inside the vertical tank, and to clean the reactor body. Therefore, the cleaning water from both sources is transported to a settling tank where flocculant is added. The raw material impurities in the used cleaning water are flocculated under the action of the flocculant. Since the reaction inside the reactor requires a certain amount of time, static sedimentation occurs inside the settling tank. During this sedimentation process, the flocculated lumps settle to the bottom. Once a certain amount of lumps accumulates at the bottom of the settling tank... The pusher end of the pusher rack pushes the block to the bottom side of the sedimentation tank. At this time, the lifting end of the lifting block plate on this side descends to seal the bottom side of the sedimentation tank, keeping the block inside the isolated area. Then, the moving end of the plug moves to open the bottom side of the sedimentation tank, and the liquid and block inside this isolated area are cleaned out. The liquid and block removed multiple times can be centrally processed. The cleaning water treated inside the sedimentation tank can be reused, which not only promotes the recycling of cleaning water but also reduces wastewater discharge and mitigates environmental pollution.

[0023] According to this application, the lifting block plate includes a fourth telescopic member and a second sealing block plate. The fourth telescopic member is fixedly connected to the sedimentation tank, the output end of the fourth telescopic member is fixedly connected to the upper part of the second sealing block plate, and the second sealing block plate is slidably connected to the sedimentation tank.

The first lifting frame 310 is located on one side of the lifting frame 110, and the first vessel 130 is connected to the lifting end of the first lifting frame 310. The second lifting frame 330 is rotatably connected to the bottom of the first linear slide rail 320 and fixedly connected to the upper part of the sliding end. The second vessel 140 is rotatably connected to the lifting end of the second lifting frame 330. There are two third motors 380. One third motor 380 is fixedly connected to the lifting end of the first lifting frame 310 and its output end is connected to the first vessel 130. The other third motor 380 is fixedly connected to the lifting end of the second lifting frame 330 and its output end is connected to the second vessel 140. The bottom of the third lifting frame 360 ​​is fixedly connected to the sliding end of the third linear slide rail 350. The rotating end of the rotating brush 370 is rotatably connected to the lifting end of the third lifting frame 360. To address the problem of inconvenient internal cleaning of reaction vessels due to frequent use, a detachable structural design enables efficient cleaning: the first lifting frame 310, in conjunction with the third motor 380, disassembles the first vessel 130 from the bottom of the second vessel 140; the second lifting frame 330, in cooperation with another third motor 380, can remove the second vessel 140 from the bottom of the vessel body 100; and then, with the aid of the first linear slide rail 320, the second lifting frame 330 and the second vessel 140 are moved, separating the vessel body 100, the first vessel 130, and the second vessel 140 from each other. This breaks through the cleaning limitations of the traditional integrated structure of reaction vessels and creates favorable conditions for subsequent in-depth cleaning. The flexibility and comprehensiveness of the cleaning process are greatly improved: the third lifting frame 360 ​​drives the rotating brush 370 to rise and fall, and combined with the movement function of the second linear slide rail 340, the rotating brush 370 can be accurately delivered to the bottom of the vessel body 100. After the lifting frame 110 adjusts the height of the vessel body 100, the upper part of the rotating brush 370 can penetrate into the interior of the vessel body 100, and the lower part can be adapted to the first vessel 130 or the second vessel 140, so as to achieve simultaneous or separate cleaning of the interior of the vessel body 100, the first vessel 130, and the second vessel 140. At the same time, the cleaning water is accurately delivered to the interior of the vessel body 100 through the vertical tank 210. With the rotation of the rotating brush 370, the thoroughness of the cleaning is ensured, and the problem of raw materials or reactants adhering to the inner wall and being difficult to remove is effectively solved. The integrated design of the entire cleaning process and components significantly improves the ease of operation: from the disassembly of the first reactor 130 and the second reactor 140, to their positioning and cleaning by the rotating brush 370, each step is seamlessly connected without the need for complex manual intervention. This not only saves cleaning time but also reduces the impact on subsequent production caused by incomplete manual cleaning, making the daily maintenance of the reactor more efficient and convenient.

[0046] According to this application, such as Figure 10 As shown, the first lifting frame 310, the second lifting frame 330 and the third lifting frame 360 ​​each include a support frame 311, a fourth motor 312, a slide 313 and a second lead screw 314. The fourth motor 312 is fixedly connected to the upper part of the support frame 311. The output end of the fourth motor 312 is connected to the second lead screw 314 for transmission. The output end of the fourth motor 312 is fixedly connected to one end of the second lead screw 314. The second lead screw 314 is rotatably connected to the support frame 311. The slide 313 is slidably connected to the support frame 311. The second lead screw 314 is threadedly connected to the slide 313.

[0047] According to this application, such as Figure 9 As shown, both the first linear slide rail 320 and the second linear slide rail 340 include a fifth motor 321, a fifth lead screw 322 and a first slider 323. The output end of the fifth motor 321 is fixedly connected to one end of the fifth lead screw 322. The fifth lead screw 322 is threadedly connected to the first slider 323. The first slider 323 is fixedly connected to the bottom of a stand 311.

[0048] According to this application, such as Figure 12 As shown, the rotating brush 370 includes a sixth motor 371 and a brush body 372. The brush body 372 is rotatably connected to one side of a slide 313. The sixth motor 371 is fixedly connected to the slide 313. The output end of the sixth motor 371 is connected to the brush body 372 in a transmission connection.

[0049] According to this application, such as Figure 11 As shown, the first vessel 130 and the second vessel 140 are both equipped with sealing gaskets on their upper parts, and both the first vessel 130 and the second vessel 140 are equipped with gear rings 131. The output end of the third motor 380 is equipped with a gear 381, which meshes with the gear ring 131.

[0050] When cleaning the reactor, cleaning water containing raw material impurities is generated. Since the amount of water used for cleaning is relatively small, investing in large-scale wastewater treatment equipment would increase the company's costs. If this cleaning water is discharged directly, it will not only waste raw materials but also pollute the environment.

[0051] According to this application, such as Figure 13 and Figure 14As shown, it also includes a cleaning water treatment component 400, which includes a water receiving tank 410, a pump 420, a sedimentation tank 430, a lifting block plate 440, a pusher frame 450, and a plug 460. The water receiving tank 410 is located below the vessel body 100 and is connected to the input end of the pump 420. The output end of the pump 420 is connected to the top of the sedimentation tank 430. The bottom of the vertical tank 210 is connected to the top of the sedimentation tank 430. The lifting block plates 440 are symmetrically arranged, and the lifting end of the lifting block plates 440 is slidably connected to the sedimentation tank 430. The pushing end of the pusher frame 450 is located inside the bottom side of the sedimentation tank 430. The plugs 460 are symmetrically arranged on both sides of the sedimentation tank 430. During use, cleaning water is used both when cleaning the rotating shaft 240 and stirring plate 260 after they are housed inside the vertical tank 210, and when cleaning the vessel body 100. Therefore, the cleaning water from both sources is transported to the sedimentation tank 430. Flocculant is added to the sedimentation tank 430, and the raw material impurities in the used cleaning water are flocculated under the action of the flocculant. Since the reaction inside the reactor requires a certain amount of time, static sedimentation occurs inside the sedimentation tank 430. During sedimentation, the flocculated lumps settle to the bottom. As the lumps accumulate at the bottom of the sedimentation tank 430... After a certain amount is collected, the pushing end of the pusher 450 pushes the block to the bottom side of the sedimentation tank 430. At this time, the lifting end of the lifting block plate 440 located on this side descends to seal the bottom side of the sedimentation tank 430, allowing the block to remain inside the isolated area. Then, the moving end of the plug 460 moves to open the bottom side of the sedimentation tank 430, at which point the liquid and block inside this isolated area are cleaned out. The liquid and block that have been removed multiple times can be centrally processed. The cleaning water that has been treated inside the sedimentation tank 430 can be reused, which on the one hand is the recycling of cleaning water, and on the other hand is to reduce wastewater discharge and reduce environmental pollution.

[0052] According to this application, such as Figure 14 As shown, the lifting block plate 440 includes a fourth telescopic member 441 and a second sealing block plate 442. The fourth telescopic member 441 is fixedly connected to the sedimentation tank 430, the output end of the fourth telescopic member 441 is fixedly connected to the upper part of the second sealing block plate 442, and the second sealing block plate 442 is slidably connected to the sedimentation tank 430.

[0053] According to this application, such as Figure 14 As shown, the pusher frame 450 includes a fifth telescopic member 451 and a pusher frame 452. The fifth telescopic member 451 is fixedly connected to the sedimentation tank 430. One side of the pusher frame 452 is located inside the sedimentation tank 430. The output end of the fifth telescopic member 451 is fixedly connected to one side of the pusher frame 452.

[0054] According to this application, such as Figure 14 As shown, the plug component 460 includes a sixth motor 461, a sixth lead screw 462, a sixth slider 463, and a sealing cover plate 464. The sixth motor 461 is fixedly connected to the sedimentation tank 430, the sixth lead screw 462 is rotatably connected to the sedimentation tank 430, the sixth slider 463 is slidably connected to the sedimentation tank 430, the sixth lead screw 462 and the sixth slider 463 are threadedly connected, and the sealing cover plate 464 is fixedly connected to the sixth slider 463.
