Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride production technology, and in particular to a slag-liquid separation device for producing polyaluminum chloride. Background Technology

[0002] Polyaluminum chloride is an inorganic polymer coagulant, mainly used in water treatment and purification processes. In the production process of polyaluminum chloride, the liquid after the reaction is a suspension containing a large amount of insoluble solid residue. In order to separate these solid residues from the polyaluminum chloride liquid and ensure the clarity and purity of the final product, a slag-liquid separation device is used for the production of polyaluminum chloride.

[0003] To address this, patent CN223276000U discloses a solid-liquid separation device for the production of polyaluminum chloride, relating to the field of polyaluminum chloride technology. The device includes a main body with a fixed plate connected to the middle of its inner cavity. A frame is connected to the lower part of the inner cavity, and a filter screen is connected inside the frame. Electric push rods are connected to both sides of the bottom of the fixed plate, and impact balls are connected to the telescopic ends of the electric push rods. Fixed blocks are connected to the side walls of the device below the frame, and a sleeve is connected to the top of each fixed block. A movable rod is movably connected inside the sleeve, with its top extending to the outside of the sleeve. This invention, through a series of structural features, can prevent small particles in the polyaluminum chloride from clogging the filter screen, thus improving the efficiency of solid-liquid separation of polyaluminum chloride. It also allows for solution circulation and filtration, preventing solution waste.

[0004] Although the solid-liquid separation device for polyaluminum chloride production described above can achieve the effect of circulating and filtering the solution to avoid waste, its applicability is low because it is inconvenient to disassemble, replace and clean the filter plates and screens, and clean the residue. Utility Model Content

[0005] The purpose of this invention is to provide a slag-liquid separation device for the production of polyaluminum chloride, thereby solving the problem that existing slag-liquid separation devices for the production of polyaluminum chloride are inconvenient to disassemble.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slag-liquid separation device for producing polyaluminum chloride, comprising a separation tank and a feed pipe;

[0007] A feed pipe is fixed to one side of the top of the separation tank, an extrusion structure is fixed to the top of the separation tank, and a fixing frame is fixed to the outside of the separation tank.

[0008] The bottom end of the fixed frame is fixed with a movable structure, and the bottom end of the movable structure is fixed with a base plate;

[0009] The bottom of the separation tank is provided with a separation component, and the bottom end of the separation tank is provided with a disassembly structure. The disassembly structure includes an end cap provided at the bottom end of the separation tank. The top two sides of the fixing frame are fixed with second electric push rods, and the bottom ends of the second electric push rods are fixed with limit plates.

[0010] When using this device, the detachable structure facilitates cleaning, thereby improving its applicability in the production of polyaluminum chloride; the extrusion structure facilitates auxiliary separation, further enhancing its ease of use; and the movable structure facilitates separation, thus improving its operational efficiency.

[0011] Preferably, the extrusion structure includes a support, a first electric push rod, a slide rod, a cover plate, and a piston plate. The cover plate is fixed to the top of the separation tank, and a support is fixed to the top of the cover plate. The first electric push rod passes through the top of the support, and slide rods pass through the interior of the support on both sides of the first electric push rod. A piston plate is provided on the top of the separation tank. Under the action of the slide rod, the stability of the piston plate during movement is enhanced, and the moved piston plate applies pressure to the sludge-liquid mixture inside the separation tank.

[0012] Preferably, the bottom end of the first electric push rod passes through the cover plate and is fixedly connected to the top end of the piston plate. The first electric push rod and the cover plate form a sliding structure. The bottom end of the slide rod passes through the cover plate and is fixedly connected to the top end of the piston plate. The slide rod, the bracket, and the cover plate form a sliding structure. Simultaneously, the separation tank drives the reciprocating movement of the filter screen and filter plate, further squeezing out the residual liquid and significantly improving the thoroughness of the sludge-liquid separation. At this time, the liquid is discharged through the discharge pipe, while the residue remains on the top of the filter plate.

[0013] Preferably, the movable structure includes a movable plate, a support plate, a turntable, a movable seat, a movable frame, a slide rail, a slide block, a guide seat, a guide rod, and a drive motor. The movable plate is fixed to the bottom of the fixed frame. A support plate is provided on one side of the movable plate, a turntable is provided on one side of the support plate, and a drive motor is installed on the other side of the support plate. A movable seat is fixed on one side of the turntable, a movable frame is sleeved on the outer side of the movable seat, guide rods are fixed on both sides of the movable frame, and guide seats are sleeved on the outer sides of the guide rods. Slide blocks are fixed on both sides of the bottom end of the movable plate, and a slide rail passes through the bottom of each slide block.

[0014] Preferably, the bottom end of the support plate is fixedly connected to the top end of the base plate, and the bottom end of the slide rail is fixedly connected to the top end of the base plate, forming a sliding structure with the slide block and the slide rail. When the turntable rotates, the turntable drives the movable frame to move via the movable seat, the movable frame drives the guide rod to reciprocate inside the guide seat, and the guide rod drives the movable plate to move. Under the action of the slide rail and the slide block, the stability of the movable plate during movement is enhanced.

[0015] Preferably, the guide rod and guide seat form a sliding structure. One side of the guide seat is fixedly connected to one side of the support plate, one end of the guide rod on one side of the movable frame is fixedly connected to one side of the movable plate, and the output end of the drive motor is fixedly connected to one side of the turntable. The moved movable plate drives the separation tank to reciprocate via the fixed frame, making the sludge and liquid more evenly distributed inside the separation tank, avoiding local accumulation. Simultaneously, the squeezing action of the piston plate ensures more thorough squeezing and prevents clogging of the filter screen and filter plate, thereby improving the overall separation efficiency.

[0016] Preferably, a discharge pipe is fixed to the bottom end of the end cap, guide grooves are provided inside the fixing frame on one side of the limiting plate, and rubber pads are fixed to one side of the top of the limiting plate. The guide grooves enhance the stability of the limiting plate during movement, and the ball bearings reduce the friction between the limiting plate and the fixing frame.

[0017] Preferably, the limiting plate and the fixing frame form a sliding structure through a guide groove. A ball bearing is rotatably connected to one side of the limiting plate, and the limiting plate contacts the inner side of the fixing frame through the ball bearing. The top of the rubber pad abuts against the bottom of the end cap. Moving the limiting plate will cause the rubber pad to move downwards, at which point the end cap will move the fixing frame. Moving the fixing frame separates the end cap from the rubber pad, facilitating the cleaning of residue at the top of the fixing frame, and also facilitating the cleaning of the filter screen and filter plate.

[0018] Preferably, the separation component includes a fixing frame, a support frame, a filter screen, and a filter plate. The fixing frame is disposed at the bottom of the separation tank, the top of the fixing frame is fixed with a filter plate, the bottom of the filter plate is disposed inside the fixing frame, and the bottom of the filter screen is disposed with a support frame.

[0019] Preferably, the bottom end of the support frame is connected to the top end of the discharge pipe, the outer side of the support frame is fixedly connected to the inner side of the fixing frame, and the bottom end of the fixing frame extends to the outside of the separator and is fixedly connected to the top end of the end cap. After the aluminum chloride slag liquid enters the interior of the separator, most of the solid particles are first intercepted by the filter plate, and then the remaining fine particles are further filtered by the filter screen. The liquid is discharged to the outside of the separator through the discharge pipe, while the solids remain on the top of the filter plate.

[0020] The present invention provides a slag-liquid separation device for the production of polyaluminum chloride, which has the following advantages:

[0021] By incorporating a detachable structure and guided by a guide groove, the stability of the limiting plate during movement is enhanced. The friction between the limiting plate and the fixed frame is reduced by the ball bearings. The moved limiting plate causes the rubber pad to move downwards, at which point the end cap moves the fixed frame. Moving the fixed frame separates the end cap from the rubber pad, facilitating the cleaning of residue at the top of the fixed frame and the cleaning of the filter screen and filter plate. This achieves the easy-to-clean function of the device, thereby improving the applicability of the slag-liquid separation device used for producing polyaluminum chloride.

[0022] By incorporating a squeezing structure, the stability of the piston plate during movement is enhanced under the action of the sliding rod. The moving piston plate applies pressure to the slag and liquid inside the separation tank, and simultaneously, in conjunction with the separation tank, drives the filter screen and filter plate to reciprocate, further squeezing out the residual liquid and significantly improving the thoroughness of slag and liquid separation. At this point, the liquid is discharged through the discharge pipe, while the residue remains on the top of the filter plate, thus realizing the function of the device in facilitating auxiliary separation and improving the convenience of using the slag and liquid separation device for producing polyaluminum chloride.

[0023] By incorporating a movable structure, when the turntable rotates, it drives the movable frame to move via the movable seat. The movable frame then drives the guide rod to reciprocate within the guide seat, which in turn drives the movable plate to move. The sliding rails and slide blocks enhance the stability of the movable plate during movement. The moved movable plate then drives the separation tank to reciprocate via the fixed frame, resulting in a more uniform distribution of slag and liquid within the separation tank and preventing localized accumulation. Simultaneously, the piston plate's squeezing action ensures more thorough squeezing and prevents clogging of the filter screen and plates, thereby improving overall separation efficiency. This design facilitates separation and enhances the working efficiency of the slag-liquid separation device used for producing polyaluminum chloride. Attached Figure Description

[0033] Reference Figure 2 and Figure 3As shown, the first electric push rod 302 is activated, which drives the piston plate 305 to move inside the separator 1. The piston plate 305 drives the slide rod 303 to move inside the cover plate 304 and the bracket 301. Under the action of the slide rod 303, the stability of the piston plate 305 during movement is enhanced. After moving, the piston plate 305 applies pressure to the sludge and liquid inside the separator 1. At the same time, the separator 1 drives the filter screen 703 and the filter plate 704 to move back and forth, further squeezing out the residual liquid and greatly improving the thoroughness of sludge and liquid separation. At this time, the liquid is discharged through the discharge pipe 601, while the residue remains on the top of the filter plate 704.

The movable structure 5 includes a movable plate 501, a support plate 502, a turntable 503, a movable seat 504, a movable frame 505, a slide rail 506, a slide block 507, a guide seat 508, a guide rod 509, and a drive motor 510. The movable plate 501 is fixed to the bottom of the fixed frame 4.

The output end of the drive motor 510 is fixedly connected to one side of the turntable 503.

[0035] Reference Figure 3 and Figure 6As shown, when the drive motor 510 is started, the drive motor 510 drives the turntable 503 to rotate. The turntable 503 will drive the movable frame 505 to move through the movable seat 504. The movable frame 505 will drive the guide rod 509 to move back and forth inside the guide seat 508. The guide rod 509 will drive the movable plate 501 to move. The movable plate 501 will drive the slide seat 507 to move outside the slide rail 506. Under the action of the slide rail 506 and the slide seat 507, the stability of the movable plate 501 during movement is enhanced. After moving, the movable plate 501 will drive the separation tank 1 to move back and forth through the fixed frame 4, so that the sludge and liquid are more evenly distributed inside the separation tank 1, avoiding local accumulation. At the same time, in conjunction with the squeezing action of the piston plate 305, the squeezing is more complete, and it can also prevent the filter screen 703 and filter plate 704 from clogging, thereby improving the overall separation efficiency.

[0036] A base plate 8 is fixed to the bottom of the movable structure 5. A separation component 7 is provided at the bottom of the separation tank 1. A disassembly structure 6 is provided at the bottom of the separation tank 1. The disassembly structure 6 includes an end cap 602 located at the bottom of the separation tank 1.

The bottom of the fixing frame 701 extends to the outside of the separation tank 1 and is fixedly connected to the top of the end cap 602.

[0037] Reference Figure 4 and Figure 5As shown, the second electric push rod 603 is activated, causing the limiting plate 604 to move inside the guide groove 605. The guide groove 605 enhances the stability of the limiting plate 604 during movement, and the ball bearings reduce the friction between the limiting plate 604 and the fixed frame 4. The moved limiting plate 604 then moves the rubber pad 606 downwards. At this time, the end cap 602 moves the fixed frame 701, separating the end cap 602 from the rubber pad 606, thus facilitating the movement of the top of the fixed frame 701. The residue is cleaned, and the filter screen 703 and filter plate 704 are also easily cleaned. After the aluminum chloride slag liquid enters the interior of the separator 1, most of the solid particles are first intercepted by the filter plate 704, and then the remaining fine particles are further filtered by the filter screen 703. The liquid is discharged to the outside of the separator 1 through the discharge pipe 601, while the solids remain on the top of the filter plate 704. By tightening the bolts with a wrench, the filter plate 704 is separated from the fixed frame 701. At this time, the filter screen 703 is moved to the outside of the fixed frame 701, which facilitates the cleaning of the filter screen 703 and filter plate 704.
