Description

Technical Field

[0001] This utility model relates to the field of slurry pump technology, and in particular to a slurry pump that is easy to clean. Background Technology

[0002] A slurry pump is a centrifugal pump specifically designed for conveying solid-liquid mixtures containing solid particles. It is widely used in industries such as mining, metallurgy, coal, power, chemical, and building materials, and is one of the core pieces of equipment in the material conveying process.

[0003] Existing slurry pumps typically use multiple bolts to assemble the casing, making quick disassembly and internal cleaning difficult and time-consuming. A utility model patent with authorization announcement number CN222010503U discloses a slurry pump that facilitates internal cleaning. This pump can move two pull rings outwards, causing the pull rods to retract into two movable slots via two connecting blocks and two limiting blocks. Simultaneously, two springs are compressed, engaging the sealing disc into the sealing slot. Releasing the pull rings allows the limiting blocks to retract into the limiting slots under the spring force, thus confining the sealing disc within the sealing slot. This facilitates both assembly and disassembly of the sealing disc for easy cleaning of the pump's interior.

[0004] However, when disassembling and installing the sealing disc of this slurry pump, it is necessary to manually pull the levers on both sides of the sealing disc simultaneously to engage it into the sealing groove. When one person is operating this process, they need to pull both levers while simultaneously controlling the insertion and removal of the sealing disc from the sealing groove, increasing the difficulty of disassembling and installing the sealing disc and hindering internal cleaning of the slurry pump. While two-person operation can avoid the inconvenience of single-person operation, it not only increases labor costs but may also prolong disassembly and assembly time and reduce the cleaning efficiency of the slurry pump due to improper coordination.

[0005] Therefore, it is necessary to develop a slurry pump that is easy to clean to address the above-mentioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a slurry pump that is easy to clean, which reduces the difficulty of disassembly and assembly during cleaning, facilitates the disassembly and assembly of the sealing disc by a single person, reduces labor costs, and improves the efficiency of disassembly, assembly, and cleaning of the slurry pump.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a slurry pump that is easy to clean, comprising a pump body, a base, and a connecting cylinder. The pump body is fixedly mounted on the base, and the connecting cylinder is fixedly connected to the feed end of the pump body. It also includes a sealing disc, which is sealed and inserted into the connecting cylinder. Connecting lugs are symmetrically fixedly connected to both sides of the outer end face of the connecting cylinder, and limit holes are formed on the connecting lugs. Insertion assemblies are provided on both sides of the outer wall of the sealing disc, opposite the connecting lugs. Each insertion assembly includes a mounting box, insertion rods, and a control component. One end of the insertion rod is adapted to be inserted into the limit hole, and the other end of the insertion rod passes through and slidably connects to one side wall of the mounting box. The control component is used to synchronously control the two insertion rods to simultaneously insert into and withdraw from the limit holes.

[0008] Furthermore, the control component includes two movable blocks, which are slidably connected to the inner wall of the mounting box and have one end fixedly connected to the plug-in rod. A drive rod is provided on the top surface of the two mounting boxes, passing through and slidably connected to the mounting box, and the drive rod is connected to the movable blocks via a connector. A pull rod is fixedly connected between the top ends of the two drive rods.

[0009] Furthermore, the connector includes a first connecting rod, a second connecting rod, and a connecting block. The connecting block is rotatably connected to the inner wall of the mounting box. One end of both the first and second connecting rods is fixedly connected to the connecting block, and the first and second connecting rods are arranged in an L-shape. A first slotted hole is formed on the first connecting rod, and a first sliding post is fixedly connected to the side wall of the moving block, the first sliding post being slidably connected within the first slotted hole. A second slotted hole is formed on the second connecting rod, and a second sliding post is fixedly connected to the side wall of the driving rod, the second sliding post being slidably connected within the second slotted hole.

[0010] Furthermore, a compression spring is fixedly connected to the side wall of the movable block away from the plug rod, and the compression spring is fixedly connected to the inner wall of the mounting box.

[0011] Furthermore, a connecting plate is fixedly connected between the two mounting boxes, and a threaded rod is rotatably connected to the top surface of the connecting plate. A threaded cylinder is fixedly connected to the bottom surface of the pull rod, and the threaded rod passes through the pull rod and is threadedly connected to the threaded cylinder.

[0012] Furthermore, a discharge pipe is fixed and connected to the pump body, and a feed pipe is fixed and connected to the outer end face of the sealing disc.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention utilizes a control mechanism to allow for the rapid removal of the sealing disc when the slurry pump needs to be disassembled for cleaning. The control mechanism simultaneously pulls two connecting rods out of the limiting holes, allowing the sealing disc to be removed from the connecting cylinder. During slurry pump installation, the sealing disc is inserted into the connecting cylinder, and the control mechanism then simultaneously inserts the two connecting rods into the limiting holes, enabling rapid installation. This reduces the difficulty of disassembly and assembly during slurry pump cleaning, facilitates rapid disassembly and assembly by a single person, reduces labor costs, minimizes equipment downtime for maintenance, and improves the efficiency of slurry pump disassembly and cleaning.

[0021] Example: Figure 1 Figure 2 and Figure 3 As shown, the system includes a pump body 1, a base 2, and a connecting cylinder 3. The pump body 1 is fixedly mounted on the base 2. The connecting cylinder 3 is fixed and connected to the feed end of the pump body 1. It also includes a sealing disc 4, which is inserted into the connecting cylinder 3. A sealing ring is provided on the inner wall of the connecting cylinder 3, and the side wall of the sealing disc 4 is tightly fitted with the sealing ring. Connecting ear plates 5 are symmetrically fixedly connected to both sides of the outer end face of the connecting cylinder 3. Limiting holes 6 are provided on the connecting ear plates 5. Insertion components are provided on both sides of the outer wall of the sealing disc 4, directly opposite the connecting ear plates 5. The insertion components include a mounting box 7, insertion rods 8, and a control component. One end of the insertion rod 8 is fitted into the limiting hole 6, and the other end of the insertion rod 8 passes through one side wall of the mounting box 7 and is slidably connected thereto. The control component is used to synchronously control the two insertion rods 8 to simultaneously insert into and withdraw from the limiting hole 6. A discharge pipe 23 is fixed and connected to the pump body 1, and a feed pipe 24 is fixed and connected to the outer end face of the sealing disc 4.

[0022] Specifically, as shown in the figure, the control component includes two movable blocks 9, which are slidably connected to the inner wall of the mounting box 7 and have one end fixedly connected to the plug-in rod 8. A drive rod 10 is provided on the top surface of the two mounting boxes 7, passing through and slidably connected to the mounting box 7. The drive rod 10 is connected to the movable blocks 9 via a connector. A pull rod 11 is fixedly connected between the top ends of the two drive rods 10.

[0023] It should be noted that the inner wall of the mounting box 7 is provided with a horizontal sliding groove, and the moving block 9 can move horizontally along the sliding groove.

[0024] Specifically, the connector includes a first connecting rod 12, a second connecting rod 13, and a connecting block 14. The connecting block 14 is rotatably connected to the inner wall of the mounting box 7. One end of both the first connecting rod 12 and the second connecting rod 13 is fixedly connected to the connecting block 14, and the first connecting rod 12 and the second connecting rod 13 are arranged in an L-shape. A first strip-shaped hole 15 is provided on the first connecting rod 12, and a first sliding post 16 is fixedly connected to the side wall of the moving block 9, and the first sliding post 16 is slidably connected in the first strip-shaped hole 15. A second strip-shaped hole 17 is provided on the second connecting rod 13, and a second sliding post 18 is fixedly connected to the side wall of the driving rod 10, and the second sliding post 18 is slidably connected in the second strip-shaped hole 17.

[0025] When the pull rod 11 is pulled upward, the drive rod 10 drives the second sliding column 18 to move upward, pushing the second connecting rod 13 to rotate around the connecting block 14 through the second slot 17, which in turn drives the first connecting rod 12 to rotate synchronously. The first connecting rod 12, through the cooperation of the first slot 15 and the first sliding column 16, pulls the moving block 9 to move away from the connecting ear plate 5, ultimately causing the plug-in rod 8 to be pulled out of the limiting hole 6. Conversely, pressing the pull rod 11 downward can push the plug-in rod 8 into the limiting hole 6.

[0026] Specifically, such as Figure 3 As shown, a connecting plate 20 is fixedly connected between the two mounting boxes 7, and a threaded rod 21 is rotatably connected to the top surface of the connecting plate 20. A threaded cylinder 22 is fixedly connected to the bottom surface of the pull rod 11, and the threaded rod 21 passes through the pull rod 11 and is threadedly connected to the threaded cylinder 22.

[0027] Working principle: When cleaning the slurry pump is required, rotating the threaded rod 21 causes the pull rod 11 to move upward under the action of the threaded cylinder 22. This causes the drive rods 10 at both ends to move the second sliding column 18 upward, pushing the second connecting rod 13 to rotate around the connecting block 14 through the second slotted hole 17, which in turn drives the first connecting rod 12 to rotate synchronously. The first connecting rod 12, through the cooperation of the first slotted hole 15 and the first sliding column 16, pulls the moving block 9 away from the connecting ear plate 5, ultimately causing the insertion rod 8 to be pulled out of the limiting hole 6. Then, the sealing disc 4 is removed from the connecting cylinder 3, and the inside of the slurry pump can be cleaned. After cleaning, after inserting the sealing disc 4 into the connecting cylinder 3, rotating the threaded rod 21 in the opposite direction drives the pull rod 11 to move downward, further driving the insertion rod 8 to move and insert it into the limiting hole 6.
