Description

Technical Field

[0001] This utility model relates to the field of sand pump inlet pipe connection technology, specifically a leak-proof inlet pipe connection device for sand pumps. Background Technology

[0002] In the working environment of a sand pump, the slurry inlet pipe connection device plays a crucial role in connecting the sand pump body with the external conveying pipeline, and its performance directly affects the overall operating effect of the sand pump.

[0003] Existing sand pump inlet pipe connection devices have many drawbacks, with poor sealing performance being a prominent issue. During sand pump operation, due to the pressure and corrosiveness of media such as slurry, leaks are very likely to occur if the connection device is not sealed tightly. Leaks not only lead to slurry waste and reduce the working efficiency of the sand pump, but may also pollute the surrounding environment, increase cleaning costs, and long-term leaks may also damage the sand pump body and connection device, shortening the service life of the equipment.

[0004] On the other hand, existing connection devices are inconvenient in terms of connection and disassembly operations. During installation, it is often difficult to ensure precise alignment and tight fixation of the connection parts, which can easily lead to misalignment and weak connection. This further affects the sealing effect and connection stability, increasing the risk of leakage. When it is necessary to maintain the sand pump or replace parts, disassembling the connection device is also difficult, which consumes a lot of time and effort and affects the maintenance efficiency and normal operation of the equipment. To address these issues, we propose a leak-proof slurry inlet pipe connection device for sand pumps. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a leak-proof slurry inlet pipe connection device for sand pumps, thereby solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a leak-proof slurry inlet pipe connection device for a sand pump, comprising a sand pump body, a sand pump slurry inlet pipe provided on the right side of the sand pump body, limit plates welded to both side walls of the sand pump slurry inlet pipe, a connecting sleeve fitted at one end of the sand pump slurry inlet pipe, a sealing rubber ring provided in the middle of the inner ring of the connecting sleeve, a connecting pipe fitted on the right side of the connecting sleeve, a fixing plate welded to both side walls of the connecting pipe, a hinge plate hinged to the side of the fixing plate away from the connecting pipe, connecting plates rotatably connected to the upper and lower parts of the hinge plate, a limit roller installed on the left side of the side of the connecting plates rotatably connected to the upper and lower parts of the hinge plate that are close to each other, a push plate welded to the right side wall of the hinge plate, and a limit threaded tube provided on the outer ring of the two push plates.

[0007] As a preferred embodiment of this utility model, the left side of the limiting plate is provided with a groove, and the groove matches the limiting roller.

[0008] As a preferred embodiment of this utility model, the two push plates are arc-shaped, and the inner ring of the push plate can be tightly attached to the outer ring of the connecting pipe.

[0009] As a preferred embodiment of this utility model, the outer rings of both push plates are provided with threads, the limiting threaded tube is an internally threaded tube, and the threads on the outer rings of the two push plates match the inner ring threads of the limiting threaded tube.

[0010] As a preferred embodiment of this utility model, push blocks are welded to both the upper and lower parts of the push plate, and multiple rotating plates are uniformly welded to the outer ring of the limiting threaded tube.

[0011] As a preferred embodiment of this utility model, a flexible hose is provided on the left side of the connecting pipe, and the connecting pipe and the flexible hose are designed as an integrated unit.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This anti-leakage slurry inlet pipe connection device for a sand pump, in terms of connection tightness and leak prevention, the limiting plates welded on both sides of the sand pump slurry inlet pipe and the limiting rollers installed on the hinge plate cooperate with each other. Through the groove opened on the left side of the limiting plate that matches the limiting roller, precise positioning is achieved, ensuring the coaxiality between the connecting sleeve, the sand pump slurry inlet pipe and the connecting pipe. At the same time, the sealing rubber ring set in the middle of the inner ring of the connecting sleeve is compressed during the connection process, enhancing the sealing performance. Two arc-shaped push plates with inner rings that can be tightly attached to the outer ring of the connecting pipe cooperate with the push plate with threads on the outer ring and the inner threaded pipe limiting threaded pipe. Tightening the limiting threaded pipe can limit the push plate, further strengthening the connection and effectively preventing leakage, so that the sand pump has stability and reliability when transporting slurry.

[0014] 2. This anti-leakage slurry inlet pipe connection device for sand pumps is convenient and versatile in operation. The push blocks welded to the upper and lower parts of the push plate and the multiple rotating plates evenly welded to the outer ring of the limiting threaded pipe make both installation and disassembly relatively simple. The integrated flexible hose set on the left side of the connection pipe makes the connection device more flexible when conveying slurry, and can adapt to different installation environments and angle requirements, thus improving the versatility of the device. This design not only facilitates the installation and maintenance of the equipment, but also reduces the difficulty of operation and improves work efficiency, making it suitable for various sand pump working scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 A leak-proof slurry inlet pipe connection device for a sand pump includes a sand pump body 1, a sealing rubber ring 14 located in the middle of the inner ring of a connecting sleeve 3, the connecting sleeve 3 being fitted onto one end of the sand pump slurry inlet pipe 2, and a connecting pipe 5 being fitted onto the right side of the connecting sleeve 3. Fixing plates 15 welded to both sides of the connecting pipe 5 provide a foundation for the installation of subsequent components.

[0021] A hinge plate 8 is hinged to the side of the fixed plate 15 away from the connecting pipe 5. A limit roller 11 is installed on the left side of the connecting plate 9 that is rotatably connected to the upper and lower parts of the hinge plate 8. The groove on the left side of the limit plate 10 matches the limit roller 11. When the connecting pipe 5 is connected to the sand pump inlet pipe 2, the limit roller 11 will be inserted into the groove of the limit plate 10 to achieve precise positioning, ensure the coaxiality between the connecting sleeve 3, the sand pump inlet pipe 2 and the connecting pipe 5, and improve the sealing effect.

[0022] A push plate 13 is welded to the right side wall of the hinge plate 8. The two push plates 13 are arc-shaped, and their inner rings can be tightly attached to the outer rings of the connecting pipe 5. The outer rings of the push plates 13 are threaded, and the limiting threaded pipe 4 is an internally threaded pipe. The threads of the two are matched. By screwing the limiting threaded pipe 4 onto the push plate 13, the push plate 13 can be limited, so that the limiting roller 11 is more tightly inserted into the groove of the limiting plate 10, further strengthening the connection. At the same time, the sealing rubber ring 14 is compressed, enhancing the sealing performance and effectively preventing leakage.

[0023] Pushing blocks 12 are welded to both the upper and lower parts of the push plate 13. When disassembly is required, the limiting threaded tube 4 is screwed in the opposite direction to unscrew it from the outer ring of the push plate 13. The push plate 13 can be moved away from the connecting tube 5 by applying a tool to the pushing block 12. The limiting roller 11 is disengaged from the groove of the limiting plate 10, and the connecting tube 5 can be separated from the sand pump inlet pipe 2. Multiple rotating plates 7 are evenly welded to the outer ring of the limiting threaded tube 4 to facilitate screwing the limiting threaded tube 4.

[0024] In addition, a flexible hose 6 is provided on the left side of the connecting pipe 5. The connecting pipe 5 and the flexible hose 6 are integrated into one unit. This design makes the connecting device more flexible when conveying mortar and can adapt to different installation environments and angle requirements.

[0025] Example 2: Please refer to Figures 1-3 In actual installation, this leak-proof slurry inlet pipe connection device is also applicable to sand pump equipment with relatively narrow installation space. First, put the connecting sleeve 3 on the sand pump slurry inlet pipe 2. Due to the narrow space, when connecting the connecting pipe 5 and the connecting sleeve 3, you can observe the positional relationship between the limiting roller 11 and the groove of the limiting plate 10, slowly rotate the connecting pipe 5, and adjust the position of the connecting pipe 5 so that the limiting roller 11 can be inserted into the groove opened on the limiting plate 10.

[0026] Next, push the push plate 13 to one side of the connecting pipe 5 and press it tightly against the outer wall of the connecting pipe 5 to make the connection tighter. By rotating the rotating plate 7 on the limiting threaded pipe 4, the limiting threaded pipe 4 can be easily screwed on and fitted onto the push plate 13. Since the push plate 13 is arc-shaped and its inner ring can be pressed tightly against the outer ring of the connecting pipe 5, the limiting threaded pipe 4 can be screwed onto the outer ring of the push plate 13 and the push plate 13 can be limited.

[0027] When disassembly is required, the limiting threaded tube 4 is rotated in the opposite direction to remove it from the connecting sleeve 3, and the pushing block 12 is pushed outward to disengage the limiting roller 11 from the groove of the limiting plate 10. The integrated design of the connecting tube 5 and the hose 6 allows for flexible bending even in narrow spaces, and the connection and disassembly operations are not affected by space limitations, ensuring the availability of the device in special environments.

[0028] Example 3: Please refer to Figures 1-3 After the sand pump has been running for a long time, it may be necessary to maintain the connecting device and replace the sealing rubber ring 14. At this time, turn the limiting threaded pipe 4 in the opposite direction to remove the limiting threaded pipe 4 from the connecting sleeve 3, and push the pushing block 12 outward so that the pushing plate 13 is away from the connecting pipe 5. At this time, the limiting roller 11 can be disengaged from the groove of the limiting plate 10, and the connecting pipe 5 can be separated from the sand pump inlet pipe 2.

[0029] After removing the connecting sleeve 3 and replacing it with a new one, the assembly process is repeated according to the above steps. During the installation process, the positioning function of the limiting plate 10 and the limiting roller 11, as well as the fastening function of the limiting threaded tube 4 and the pushing plate 13, are used again to ensure that the connecting device has sealing and stability.

[0030] The integrated design of the connecting pipe 5 and hose 6 makes maintenance easier, eliminating the need for additional handling of the connection between the hose 6 and the connecting pipe 5, thus improving maintenance efficiency. At the same time, due to the reasonable structural design of the connecting device, it can still maintain good sealing performance and connection stability after multiple disassemblies and installations, extending the service life of the device.

[0031] Implementation Results: In terms of connection tightness and leakage prevention, the limiting plates 10 welded on both sides of the sand pump inlet pipe 2 and the limiting rollers 11 installed on the hinge plate 8 cooperate with each other. Through the groove on the left side of the limiting plate 10 that matches the limiting rollers 11, precise positioning is achieved, ensuring the coaxiality between the connecting sleeve 3, the sand pump inlet pipe 2, and the connecting pipe 5. At the same time, the sealing rubber ring 14 set in the middle of the inner ring of the connecting sleeve 3 is compressed during the connection process, enhancing the sealing performance. The two arc-shaped push plates 13 whose inner rings can be tightly attached to the outer ring of the connecting pipe 5, together with the push plate 13 with threads on the outer ring and the internal threaded pipe limiting threaded pipe 4, can limit the push plate 13 by screwing the limiting threaded pipe 4, further strengthening the connection and effectively preventing leakage. This makes the sand pump stable and reliable when transporting mortar.

[0032] In terms of ease of operation and versatility, the push block 12 welded to the upper and lower parts of the push plate 13 and the multiple rotating plates 7 uniformly welded to the outer ring of the limiting threaded pipe 4 make both installation and disassembly relatively simple. The integrated flexible hose 6 set on the left side of the connecting pipe 5 makes the connecting device more flexible when conveying mortar, and can adapt to different installation environments and angle requirements, thus improving the versatility of the device. This design not only facilitates the installation and maintenance of the equipment, but also reduces the difficulty of operation and improves work efficiency, making it suitable for various sand pump working scenarios.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
