Description

Technical Field

[0001] The utility model relates to the technical field of a wear-resistant sleeve for a slurry pump, and in particular to a wear-resistant sleeve for a slurry pump. Background Art

[0002] A slurry pump is a pump specifically designed to transport slurries containing solid particles (such as gangue, sand, and gravel). Slurry pumps are commonly used in various industries, including mining, metallurgy, coal, power, and chemical industries, to process waste, ore, tailings, coal slime, and other liquids containing particles. A slurry pump jacket is a protective covering that covers the internal components of the pump, reducing wear and extending the pump's service life. The jacket is typically made of wear-resistant material to withstand the wear and tear of slurries containing solid particles.

[0003] Existing slurry pumps are mostly of the melt-cast one-piece type and the split type. Among them, the split type slurry pump has the following technical problems during use: when the sheath is damaged, the staff is required to cut it off, which increases the labor intensity of the staff. At the same time, during the use of the sheath, the openings at the lower and upper parts are most severely worn and damaged. Due to the damage to one part, the entire sheath or even the entire device needs to be replaced, resulting in high equipment costs, which makes it inconvenient to put the sheath into actual use in production equipment. Utility Model Content

[0004] The utility model provides a wear-resistant sleeve for a slurry pump, which reduces the manufacturing cost, increases the service life of the sleeve, and facilitates the actual use of the sleeve in production equipment.

[0005] The technical solution of the utility model is as follows:

[0006] A wear-resistant sleeve of a slurry pump includes a connecting plate, wherein the left and right side surfaces of the lower end of the connecting plate are respectively detachably fixedly connected to a first sleeve and a second sleeve, the inner walls of the first sleeve and the second sleeve are both detachably fixedly connected to a second clamping block, the left and right sides of the upper end of the connecting plate are both detachably fixedly connected to the outlet sleeve, the inner walls of each outlet sleeve are both detachably fixedly connected to the first clamping block, and each first clamping block is clamped to the second clamping block located on the same side.

[0007] Furthermore, a limiting groove is provided on the first clamping block, and a plurality of limiting pins are fixedly connected to the limiting groove. The first clamping block is fixedly connected to the limiting block and the first interlocking block on the side away from the limiting pins, and the limiting block and the first interlocking block both abut and slide against the second clamping block.

[0008] Furthermore, each outlet sleeve inner wall is fixedly connected to a limit plate, and a plurality of alignment grooves are provided on the limit plate. The bottom surface of the limit groove abuts against the side surface of the limit plate facing the outlet sleeve, and each limit pin abuts against the inner wall of each alignment groove.

[0009] Furthermore, each of the second clamping blocks is fixedly connected to a second embedding block, an embedding groove is provided on the first embedding block, and the width of the second embedding block is the same as the width of the embedding groove.

[0010] Furthermore, each outlet sleeve is provided with two positioning grooves, and each first clamping block is threadedly connected to two screws on one side facing the outer wall of the outlet sleeve, and each screw abuts against the inner wall of each positioning groove.

[0011] Furthermore, a countersunk groove is provided on the outer wall of each of the positioning grooves, and the side edge of the screw head abuts against the inner wall of the countersunk groove.

[0012] Furthermore, the connections between the outlet sleeve, the first sleeve, the second sleeve and the connecting plate are all connected with sealing strips.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, this embodiment proposes a wear-resistant sleeve for a slurry pump, including a connecting plate 2, a first sleeve 5 and a second sleeve 6, which are respectively detachably fixedly connected to the left and right side surfaces of the lower end of the connecting plate 2, and the inner walls of the first sleeve 5 and the second sleeve 6 are both detachably fixedly connected to the second clamping block 7, and the two outlet sleeves 1 are respectively detachably fixedly connected to the left and right sides of the upper end of the connecting plate 2, and the inner wall of each outlet sleeve 1 is detachably fixedly connected to each first clamping block 3, and each first clamping block 3 is clamped with the second clamping block 7 on the same side, so that the entire sleeve adopts a multi-part split installation, and the water outlet component and the water inlet component of the sleeve can be replaced and disassembled as a single component, so that the most severely damaged part inside the sleeve can be replaced separately, ensuring the connection strength of each component and the sealing after connection, reducing the cost, increasing the service life of the sleeve, and facilitating the actual use of the sleeve in production equipment.

[0025] like Figure 2 and Figure 3 As shown, the limiting groove 31 is opened on the first clamping block 3, so that the area of ​​the connection part of the first clamping block 3 and the limiting plate 11 is increased, that is, the length of the gap between the first clamping block 3 and the outlet sleeve 1 is increased, so that it is difficult for mortar to leak from the gap here, thereby increasing the sealing performance. Several limiting pins 34 are fixedly connected to the limiting groove 31, and the limiting block 32 and the first interlocking block 33 are respectively fixedly connected to the side of the first clamping block 3 away from the limiting pin 34. The limiting block 32 and the first interlocking block 33 are both abutted and slid against the second clamping block 7, so that when the operator connects the outlet sleeve 1 with the first sleeve 5 or the second sleeve 6, the limiting block 32 is used to follow the bottom surface of the second clamping block 7, and then the first interlocking block 33 and the second interlocking block 8 are interlocked and connected.

[0026] like Figure 2 and Figure 3As shown, the inner wall of each outlet sleeve 1 is fixedly connected to each limit plate 11, and a plurality of alignment grooves 12 are opened on the limit plate 11. The bottom surface of the limit groove 31 abuts against the side of the limit plate 11 facing the outlet sleeve 1, so that the area of ​​the connection part between the first clamping block 3 and the limit plate 11 is increased, and each limit pin 34 abuts against the inner wall of each alignment groove 12. The characteristics of the limit pin 34 are used to confirm the positive and negative directions of the first clamping block 3. The characteristics of the opposite sides of each component are different, which is convenient for the operator to identify the side of each component, facilitates the connection between the first clamping block 3 and the outlet sleeve 1, and then facilitates the operator to install the components, reducing the labor intensity of the operator.

[0027] like Figures 3 to 6 As shown, each second clamping block 7 is fixedly connected to each second interlocking block 8, and the interlocking groove 331 is opened on the first interlocking block 33. The width of the second interlocking block 8 is the same as the width of the interlocking groove 331. When the first interlocking block 33 and the second interlocking block 8 are fully interlocked, the contact area between the first interlocking block 33 and the second interlocking block 8 is increased, making it difficult for mortar to leak from the tortuous gap, thereby improving the sealing performance of the two after interlocking, and at the same time increasing the torque between the two, ensuring the strength of the connection between the outlet sleeve 1 and the first sleeve 5 and the second sleeve 6 respectively, so that the sleeve will not fall off easily even if it is subjected to high-pressure mortar.

[0028] like Figure 4 As shown, two positioning grooves 13 are provided on a single outlet casing 1, and two screws 4 are both threadedly connected to a single first clamping block 3 toward the outer wall of the outlet casing 1. Each screw 4 abuts against the inner wall of each positioning groove 13. The alignment of the screw 4 with the positioning groove 13 facilitates the connection between the outlet casing 1 and the first clamping block 3 by the operator, thereby highlighting the appearance characteristics of the components and reducing the difficulty of installing the components.

[0029] like Figure 4 As shown, the countersunk groove 131 is opened on the outer wall of the positioning groove 13, and the side edge of the head of the screw 4 abuts against the inner wall of the countersunk groove 131. After the screw 4 is fully tightened, the head of the screw 4 and the countersunk groove 131 will exert force on each other, so that the connection between the first clamping block 3 clamped by the screw 4 and the outlet sleeve 1 can be tighter, reducing the working pressure of the screw 4 and the shear force on the screw 4, which is convenient for the operator to disassemble and replace it later.

[0030] like Figures 1 to 6 As shown, each sealing strip is respectively connected between the outlet sleeve 1, the first sleeve 5, the second sleeve 6 and the connecting plate 2. The sealing strip can prevent the connection parts between the outlet sleeve 1, the first sleeve 5, the second sleeve 6 and the connecting plate 2 from remaining sealed, so that the mortar will not flow out from the gaps in the connection parts, thereby ensuring the sealing of the sleeve and the protective effect of the sleeve on the pump body.

[0031] The working principle of this embodiment is:

[0032] The first housing 5, the second housing 6 and the two outlet housings 1 are all connected and fixed by the connecting plate 2 of the middle component. When it is found that the wear of the water outlet part of the sheath has reached the specified standard, the staff will disassemble the mortar pump, and then expose the sheath inside the mortar pump, and check the wear condition inside the sheath again. According to the wear condition, the disassembly and assembly tasks are formulated to determine whether both outlet housings 1 should be removed;

[0033] When only one is to be removed, the outlet sleeve 1 on one side is removed from the connecting plate 2, and then the screw 4 on that side is loosened with a suitable wrench. Because the connection area between the first interlocking block 33 and the second interlocking block 8 is large, and the friction between the two is relatively large, the outlet sleeve 1 to be replaced can be pulled out upward by exerting force on the circular edge at the outlet of the outlet sleeve 1, and then the outlet sleeve 1 to be replaced is aligned with the screw 4 through the positioning groove 13, and then the replaced outlet sleeve 1 is connected to the connecting plate 2;

[0034] When both need to be removed, remove both outlet sleeves 1 from the connecting plate 2, and apply force to the side of the circular ring outside the outlet sleeve 1 to separate the first clamping block 3 with the first mosaic block 33 from the second mosaic block 8. After both outlet sleeves 1 are removed, use a suitable wrench to unscrew all the screws 4 on both sides, and then separate the outlet sleeve 1 to be replaced from the first clamping block 3, replace it with a new outlet sleeve 1 and reconnect it with the old first clamping block 3. Then, the two outlet sleeves 1 that have been connected are connected to both sides of the connecting plate 2 in turn through the first mosaic block 33 and the second mosaic block 8.

[0035] When it is found that the water inlet of the sheath is severely worn, the two first sleeves 5 and the second sleeve 6 are replaced in the same manner as the outlet sleeve 1, and finally the maintained sheath is reinstalled into the pump body to protect the inner wall of the pump body.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
