Description

Technical Field

[0001] This utility model relates to the field of slurry pump technology, specifically to a slurry pump head that can be quickly disassembled and assembled. Background Technology

[0002] Slurry pumps are mainly used to transport fluid media containing solid particles, such as mineral slurries and coal slurries in industries like metallurgy, coal, chemicals, power, and mining. Due to the special nature of the working medium, the internal parts of the pump head suffer severe wear and corrosion during operation. Therefore, it is necessary to regularly replace components such as the wear-resistant sleeve inside the pump head to ensure the pump's efficiency and service life. Traditionally, the pump head of a slurry pump is fixed to the pump body and pump cover by multiple screws. This connection method requires unscrewing each screw individually during disassembly, which is cumbersome, time-consuming, and reduces the convenience and efficiency of maintenance, making it difficult to meet the requirements for rapid equipment maintenance in industrial production. Existing technology uses bolts to fix the slurry pump impeller and reverses the rotation of the drive shaft to separate the pump head from the drive shaft. However, tightening the impeller with bolts requires tools, which is relatively complex. Therefore, there is an urgent need for a device that can effectively solve the above problems and allow for quick fixation of the slurry pump impeller without the need for tools. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a slurry pump head that can be quickly disassembled and assembled, solving the technical problem of complicated operation when disassembling the slurry pump head as a whole in related technologies.

[0004] According to one aspect, at least one embodiment of the present invention provides a quick-assembly and disassembly slurry pump head, including a volute and pump covers disposed at both ends of the volute. A first protective plate and a second protective plate are respectively provided on the side of each pump cover near the center of the volute. An impeller is rotatably disposed between the first protective plate and the second protective plate. The first and second protective plates are capable of clamping the impeller to lock it or releasing it to unlock it. The pump head also includes: A clamping assembly is disposed on the pump cover. The clamping assembly is used to clamp the first guard plate and the second guard plate to lock the impeller in a locked state. The clamping assembly includes: A pressure member is slidably disposed on the pump cover. The pressure member can slide through the pump cover and abut against the first guard plate or the second guard plate to clamp the impeller between the first guard plate and the second guard plate. An eccentric wheel is rotatably mounted on the pump cover. The side wall of the eccentric wheel is used to abut against the pressing member. The eccentric wheel can push the pressing member to slide by rotating to lock the impeller, or the eccentric wheel can release the abutment from the pressing member to unlock the impeller.

[0005] For example, at least one embodiment of this utility model provides a quick-assembly and disassembly slurry pump head, wherein the pressure-retaining component includes: A pressure bar is slidably disposed on the pump cover, and one end of the pressure bar can penetrate the pump cover and abut against the first protective plate or the second protective plate; A pressure plate is located at the other end of the pressure rod and is used to abut against the eccentric wheel.

[0006] For example, at least one embodiment of this utility model provides a quick-assembly and disassembly slurry pump head, wherein the clamping assembly further includes: An elastic element is sleeved on the outer periphery of the pressing element. One end of the elastic element abuts against the pump cover, and the other end abuts against the pressing plate. The elastic element is used to elastically push the pressing plate to make the pressing rod move away from the first guard plate or the second guard plate.

[0007] For example, at least one embodiment of this utility model provides a quick-assembly and disassembly slurry pump head, wherein the end face of the pump cover away from the center of the volute includes a mounting bracket, the pressing member is disposed on the mounting bracket, the mounting bracket is also provided with a rotating shaft, and the eccentric wheel is rotatably disposed on the rotating shaft.

[0008] For example, at least one embodiment of the present invention provides a quick-assembly and disassembly slurry pump head, wherein the first guard plate and the second guard plate have a plurality of grooves, the grooves being capable of accommodating a sealing element, the sealing element being located between the volute and the first guard plate or the second guard plate.

[0009] For example, at least one embodiment of this utility model provides a quick-assembly and disassembly slurry pump head, wherein the impeller can be connected to the drive shaft of the drive component via a thread.

[0010] For example, at least one embodiment of this utility model provides a quick-assembly and disassembly slurry pump head, wherein the volute and the pump cover are provided with uniformly distributed reinforcing ribs.

[0011] For example, at least one embodiment of this utility model provides a quick-disassembly slurry pump head, wherein the first guard plate and the second guard plate have bosses on their end faces near the pump cover, and the bosses are used to abut against the pressing member.

[0012] The beneficial effects of this utility model are as follows: In this invention, the cooperation between the pressing component and the eccentric wheel in the clamping assembly utilizes the change in eccentricity during the rotation of the eccentric wheel to push the pressing component. This allows for impeller locking and unlocking without the need for external tools, solving the problem of complex operations caused by the use of tools in existing technologies where impellers are fixed with bolts. The pressing component is slidably mounted on the pump cover, ensuring precise contact with the guard plate under the push of the eccentric wheel. This guarantees the clamping effect of the first and second guard plates on the impeller, allowing the impeller to operate stably in the locked state. The eccentric wheel, rotating on the pump cover, has a simple structure and is easy to operate. Rotation allows for the pushing and resetting of the pressing component. Combined with the sliding action of the pressing component, this enables rapid switching between the impeller's locked and unlocked states, improving the disassembly and assembly efficiency during slurry pump head maintenance. Simultaneously, the clamping assembly achieves clamping and releasing of the impeller by the first and second guard plates, replacing the traditional method of connecting the pump body and pump cover with multiple bolts. This reduces the number of steps required for disassembly, further meeting the needs of rapid equipment maintenance in industrial production and contributing to ensuring the working efficiency and service life of the slurry pump.

[0020] like Figures 1-4As shown, this invention illustrates a quick-assembly and disassembly slurry pump head according to one embodiment of the present invention. The pump head includes a volute 1 with both ends fixedly connected to a pump cover 2. The surfaces of the two pump covers 2 near the center of the volute 1 are respectively abutted against a first protective plate 3 and a second protective plate 4. An impeller 5 is rotatably positioned between the first protective plate 3 and the second protective plate 4. Several sets of clamping components 6 are evenly arranged circumferentially along the pump cover 2. A pressing member 601 is slidably disposed within a hole in the pump cover 2, penetrating the thickness direction of the pump cover 2. The pressing member 601 can slide along the axial direction of the sliding hole, and during sliding, the end of the pressing member 601 away from the eccentric wheel 602 can penetrate the pump cover 2 and abut against the outer surface of the first protective plate 3 or the second protective plate 4. The eccentric wheel 602 is rotatably connected to the outer wall of the pump cover 2 via a rotating shaft. The axis of the rotating shaft is offset from the geometric center of the eccentric wheel 602, and the outer peripheral sidewall of the eccentric wheel 602 can contact the end of the pressing member 601 near the eccentric wheel 602. When it is necessary to lock the impeller 5, rotate the eccentric wheel 602. Due to the eccentricity between the geometric center of the eccentric wheel 602 and the axis of rotation, as the eccentric wheel 602 rotates, its outer peripheral sidewall gradually comes into contact with the pressing member 601 and pushes the pressing member 601 to slide along the sliding hole towards the guard plate. After the pressing member 601 passes through the pump cover 2, it comes into contact with the first guard plate 3 or the second guard plate 4, thereby pushing the first guard plate 3 and the second guard plate 4 closer together and clamping the impeller 5, so that the impeller 5 is in a locked state. When it is necessary to unlock the impeller 5, rotate the eccentric wheel 602 in the opposite direction. The outer peripheral sidewall of the eccentric wheel 602 gradually disengages from the pressing member 601. Under the action of its own gravity or restoring force, the pressing member 601 slides along the sliding hole away from the guard plate. After the first guard plate 3 and the second guard plate 4 lose their pressing force, they separate from each other, releasing the impeller 5, so that the impeller 5 is in an unlocked state.

[0021] The engagement of the pressing component 601 and the eccentric wheel 602 in the clamping assembly 6 utilizes the change in eccentricity of the eccentric wheel 602 during rotation to push the pressing component 601. This allows for locking and unlocking of the impeller 5 without the need for external tools, solving the problem of complex operation caused by the need for tools when fixing the impeller 5 with bolts in the prior art. The pressing component 601 is slidably mounted on the pump cover 2, ensuring that it can accurately abut against the guard plate under the push of the eccentric wheel 602, guaranteeing the clamping effect of the first guard plate 3 and the second guard plate 4 on the impeller 5, and enabling the impeller 5 to work stably in the locked state. The eccentric wheel 602 is rotatably mounted on the pump cover 2. Its simple structure and convenient operation allow for the pushing and resetting of the pressing component 601 by rotation. Combined with the sliding action of the pressing component 601, it enables rapid switching between the locked and unlocked states of the impeller 5, improving the disassembly and assembly efficiency during the maintenance of the slurry pump head. Meanwhile, the first guard plate 3 and the second guard plate 4 clamp and release the impeller 5 through the clamping assembly 6, which replaces the traditional method of connecting the pump body and the pump cover 2 with multiple bolts. This reduces the operation steps during disassembly, further meets the needs of rapid equipment maintenance in industrial production, and helps to ensure the working efficiency and service life of the slurry pump.

[0022] like Figure 4 As shown, the pressing member 601 consists of a pressing rod 6011 and a pressing plate 6012. The pressing rod 6011 slides through the sliding hole of the pump cover 2. One end of the rod away from the pressing plate 6012 can penetrate the pump cover 2 and abut against the outer side of the first guard plate 3 or the second guard plate 4. The other end is fixedly connected to the pressing plate 6012. The pressing plate 6012 can contact the outer peripheral sidewall of the eccentric wheel 602. When the impeller 5 is locked, the eccentric wheel 602 is rotated, and its outer peripheral sidewall first contacts the pressing plate 6012. As the eccentric wheel 602 continues to rotate, due to the eccentricity, the eccentric wheel 602 applies a thrust along the axis of the pressing rod 6011 to the pressing plate 6012. The pressing plate 6012 drives the pressing rod 6011 to slide along the sliding hole towards the guard plate. After penetrating the pump cover 2, the pressing rod 6011 pushes the first guard plate 3 and the second guard plate 4 to clamp the impeller 5. When unlocking, the eccentric wheel 602 rotates in the opposite direction, and its outer peripheral sidewall disengages from the pressure plate 6012. The pressure rod 6011 and the pressure plate 6012 slide in the opposite direction along the sliding hole under their own weight or the action of the restoring force, and the first guard plate 3 and the second guard plate 4 separate to release the impeller 5.

[0023] The combined structure of the pressure rod 6011 and the pressure plate 6012 allows the force of the eccentric wheel 602 to be transmitted to the pressure rod 6011 through the pressure plate 6012. This increases the contact area between the eccentric wheel 602 and the pressure member 601, preventing excessive local stress on the eccentric wheel 602 that could damage the pressure member 601. Simultaneously, it ensures stable force transmission to the pressure rod 6011, guaranteeing its pushing effect on the guard plate. The pressure plate 6012 provides a stable point of application for the eccentric wheel 602, making the contact between the eccentric wheel 602 and the pressure member 601 more reliable during rotation, reducing slippage, and improving the stability of the impeller 5 locking and unlocking operations. The pressure bar 6011 slides through the pump cover 2, ensuring the overall sliding guidance of the pressure bar 601. Combined with the contact relationship between the pressure plate 6012 and the eccentric wheel 602, the sliding stroke of the pressure bar 601 is more precise, further enhancing the reliability of the clamping of the impeller 5 by the first guard plate 3 and the second guard plate 4. At the same time, it simplifies the structure of the pressure bar 601, making it easier to process and assemble.

[0024] like Figure 4 As shown, the clamping assembly 6 also includes an elastic element 603, which is sleeved on the outer periphery of the pressure rod 6011 and located between the pump cover 2 and the pressure plate 6012. One end of the elastic element 603 abuts against the outer side of the pump cover 2, and the other end abuts against the side surface of the pressure plate 6012 near the pressure rod 6011. When the impeller 5 is locked, the eccentric wheel 602 is rotated, and its outer peripheral sidewall pushes the pressure plate 6012 towards the pump cover 2. The pressure plate 6012 compresses the elastic element 603, and at the same time, it drives the pressure rod 6011 to slide along the sliding hole towards the guard plate. After the pressure rod 6011 passes through the pump cover 2, it pushes the first guard plate 3 and the second guard plate 4 to clamp the impeller 5. At this time, the elastic element 603 is in a compressed state and stores elastic potential energy. When it is necessary to unlock the impeller 5, the eccentric wheel 602 is rotated in the opposite direction. The outer peripheral sidewall of the eccentric wheel 602 gradually disengages from the pressure plate 6012. The elastic element 603 releases its elastic potential energy and elastically pushes the pressure plate 6012 to move away from the pump cover 2. The pressure plate 6012 drives the pressure rod 6011 to slide along the sliding hole away from the guard plate. The pressure rod 6011 disengages from the first guard plate 3 or the second guard plate 4, and the first guard plate 3 and the second guard plate 4 separate to release the impeller 5.

[0025] like Figures 1-4 As shown, a mounting bracket 604 is fixedly provided on the end face of the pump cover 2 away from the center of the volute 1, and a pressing member 601 is disposed between the mounting brackets 604. A rotating shaft 6041 is also fixedly provided on the mounting bracket 604. The axis of the rotating shaft 6041 coincides with the axis of the rotating shaft 6041 of the eccentric wheel 602. The eccentric wheel 602 is sleeved on the outer circumference of the rotating shaft 6041 and rotates in cooperation with the rotating shaft 6041. The outer peripheral sidewall of the eccentric wheel 602 can abut against the end of the pressing member 601 near the rotating shaft 6041.

[0026] When it is necessary to lock the impeller 5, the eccentric wheel 602 rotates around the rotating shaft 6041. The outer peripheral wall of the eccentric wheel 602 pushes the pressing member 601 to slide along the sliding hole of the mounting bracket 604 towards the center of the volute 1. After passing through the pump cover 2, the pressing member 601 abuts against the first guard plate 3 or the second guard plate 4, pushing the first guard plate 3 and the second guard plate 4 to clamp the impeller 5. When it is necessary to unlock the impeller 5, the eccentric wheel 602 rotates in the opposite direction around the rotating shaft 6041. The outer peripheral wall of the eccentric wheel 602 disengages from the pressing member 601, and the pressing member 601 slides along the sliding hole of the mounting bracket 604 away from the center of the volute 1. The first guard plate 3 and the second guard plate 4 separate and release the impeller 5.

[0027] like Figure 3 As shown, the first guard plate 3 and the second guard plate 4 each have several grooves 7 on their sides facing the volute 1. The grooves 7 are spaced apart circumferentially along the first guard plate 3 and the second guard plate 4. The sealing element 8 is placed in the groove 7, and part of the structure of the sealing element 8 protrudes from the opening end of the groove 7 facing the volute 1. When the first guard plate 3 and the second guard plate 4 are assembled with the volute 1, the sealing element 8 is located between the inner wall surface of the volute 1 and the side of the first guard plate 3 or the second guard plate 4, and the sealing element 8 is compressed between the volute 1 and the guard plate. When the impeller 5 is in the locked state, the first guard plate 3 and the second guard plate 4 remain in contact with the volute 1 under the action of the clamping assembly 6, and the sealing element 8 is continuously compressed, filling the gap between the volute 1 and the guard plate. When the impeller 5 is in the unlocked state, and the first guard plate 3 and the second guard plate 4 are separated from the volute 1, the sealing element 8 moves with the guard plate and remains in the groove 7. The seal 8 is compressed between the volute 1 and the guard plate, which can effectively fill the gap between the two, prevent the conveyed fluid medium containing solid particles from leaking out of the gap, reduce the corrosion of the medium to other internal components of the pump head, and avoid pressure loss caused by medium leakage, thus ensuring the working efficiency of the slurry pump.

[0028] like Figures 1-4 As shown, the impeller 5 has an internal threaded hole on the side facing the drive component, and the drive shaft end of the drive component has an external thread. The internal threaded hole and the external thread are compatible. The impeller 5 is connected by screwing the internal threaded hole into the external thread of the drive shaft. When the internal and external threads are fully engaged, the impeller 5 is fixed to the drive shaft and can rotate synchronously with the drive shaft. When assembling the impeller 5, align the internal threaded hole of the impeller 5 with the external thread of the drive shaft, and rotate the impeller 5 to gradually screw them together until the impeller 5 and the drive shaft are axially positioned. When disassembling the impeller 5, rotate the impeller 5 in the opposite direction to gradually disengage the internal and external threads until the impeller 5 is completely separated from the drive shaft.

[0029] like Figure 1As shown, reinforcing ribs 9 are provided on the outer surfaces of both the volute 1 and the pump cover 2, and are evenly distributed along their outer surfaces. The extending direction of the reinforcing ribs 9 matches the contours of the volute 1 and the pump cover 2, and the reinforcing ribs 9 are fixedly connected to both the volute 1 and the pump cover 2. During the operation of the slurry pump, pressure is generated inside the volute 1 due to the conveying of fluid containing solid particles, while the pump cover 2 is subjected to pressure from the clamping assembly 6 and the force transmitted by the medium. The reinforcing ribs 9 can disperse these forces, enhancing the structural strength of the volute 1 and the pump cover 2. When the pump head is disassembled or assembled, the reinforcing ribs 9 can reduce deformation of the volute 1 and the pump cover 2 under external force, ensuring the relative stability of the components.

[0030] like Figure 1 As shown, both the first guard plate 3 and the second guard plate 4 have protrusions 10 on their end faces near the pump cover 2. The protrusions 10 are fixedly connected to the guard plates, and their positions correspond to the sliding path of the pressing member 601. When the pressing member 601 slides towards the guard plate under the push of the eccentric wheel 602, the end of the pressing member 601 away from the eccentric wheel 602 can abut against the end face of the protrusion 10 away from the guard plate. During the locking process of the impeller 5, the eccentric wheel 602 rotates and pushes the pressing member 601 to slide. After the pressing member 601 contacts the protrusion 10, it continues to push the protrusion 10, thereby causing the first guard plate 3 and the second guard plate 4 to move closer to each other and clamp the impeller 5. When unlocking, the pressing member 601 disengages from the protrusion 10, and the first guard plate 3 and the second guard plate 4 separate under their own or other component actions, releasing the impeller 5. The boss 10 can be provided with an internal threaded hole, and the pressure rod 6011 is provided with an external thread. The pressure rod 6011 is threadedly connected to the boss 10, which can more effectively prevent the first guard plate 3 and the second guard plate 4 from shaking when the slurry pump is working.
