Description

Technical Field

[0001] This utility model relates to the field of sand pump technology, specifically a sand pump with a structure for isolating debris. Background Technology

[0002] In sand pump applications, the sand pump body is the core working component, and its output end is connected to the feed pipe to realize the material conveying. However, in actual operation, the material is often mixed with various impurities. These impurities can easily enter the sand pump and interfere with its normal operation. For example, impurities may block the flow channel inside the sand pump, affecting the material conveying efficiency, or even damage the internal components of the sand pump, shortening the service life of the sand pump, increasing the equipment maintenance cost and downtime, and thus affecting the stability and efficiency of the entire production process.

[0003] To address the aforementioned issues, a filter structure might be installed at the feed end of the sand pump to block debris. However, commonly used filter structures have limitations. For instance, debris easily adheres to the surface of the filter structure, causing the filter mesh to become clogged quickly, reducing filtration efficiency and affecting the normal feed of the sand pump. Furthermore, cleaning debris attached to the filter structure is often cumbersome, requiring the machine to be stopped and the filter structure disassembled. This is not only inconvenient to operate but also further impacts production progress. Therefore, a sand pump with a more effective debris isolation structure and easy debris cleaning is needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sand pump with a debris isolation structure to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a sand pump with a debris isolation structure, including a sand pump body, an inlet pipe installed at the output end of the sand pump body via a flange, a screen installed at the end of the inlet pipe away from the sand pump body, a filter screen plate installed at the end of the inlet pipe inside the screen, a rotating rod extending to the outside of the screen being rotatably connected to the bottom surface of the filter screen plate, sleeves installed on the upper outer ring, middle outer ring and lower outer ring of the rotating rod inside the screen, three connecting plates evenly installed on the outer ring of the sleeves, a second cleaning plate installed on the side of the connecting plate away from the sleeve, a first cleaning plate installed on the upper part of the second cleaning plate, and a blocking block provided at the bottom of the screen.

[0006] As a preferred embodiment of this utility model, the mesh cover is shaped like a shuttle, and the side of the second cleaning plate away from the connecting plate is attached to the inner wall of the mesh cover.

[0007] As a preferred technical solution of this utility model, the filter screen is a hollow frustum shape and has mesh holes on its outer surface, and one side of the first cleaning plate is attached to the outer surface of the filter screen.

[0008] As a preferred embodiment of this utility model, the rotating rod passes through the blocking block, and a rubber sealing ring is provided at the upper part of the rotating rod passing through the blocking block.

[0009] As a preferred embodiment of this utility model, the lower outer ring of the rotating rod is welded with a threaded tube, and the outer ring of the rotating rod is provided with a limiting nut that matches the threaded tube.

[0010] As a preferred embodiment of this utility model, a rotating plate is installed at the bottom end of the rotating rod, and a plurality of push rods are evenly installed on the outer ring of the rotating plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This sand pump with a debris isolation structure achieves dual filtration of the material entering the sand pump by installing a screen cover at one end of the feed pipe at the output end of the sand pump body and a filter screen plate at the end of the feed pipe located inside the screen cover. The screen cover can initially block larger debris, while the filter screen plate can further filter smaller debris, effectively preventing debris from entering the interior of the sand pump body. This avoids problems such as wear and blockage of internal parts of the sand pump caused by debris, thereby ensuring the stable operation of the sand pump, extending the service life of the sand pump, reducing equipment maintenance costs and downtime, and improving production efficiency.

[0013] 2. This sand pump with a debris isolation structure allows operators to remove the blocking block from the screen cover and filter screen when debris adheres to the inner wall or filter screen. The operator can then manually rotate the push rod to rotate the rotating plate and rod, causing the first and second cleaning plates to clean the filter screen and inner wall of the screen cover respectively. The debris will be discharged through the opening at the bottom of the screen cover, ensuring normal feeding of the sand pump. No machine shutdown or disassembly is required, making operation simple and quick. This design effectively cleans debris, prevents blockage of the mesh, ensures the filtration efficiency of the filter screen and screen cover, and allows the sand pump to feed and operate continuously and stably.

[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 1-4 A sand pump with a debris isolation structure includes components such as a sand pump body 1, a feed pipe 2, and a mesh cover 3. The output end of the sand pump body 1 is tightly connected to the feed pipe 2 through a flange to ensure the sealing and stability of the connection. A shuttle-shaped mesh cover 3 is installed at the end of the feed pipe 2 away from the sand pump body 1. The shuttle-shaped design helps to reduce the resistance when the material enters, while increasing the contact area with the material and improving the filtration effect.

[0021] At one end of the feed pipe 2 located inside the mesh cover 3, a hollow frustum-shaped filter screen plate 10 is installed. The outer surface of the filter screen plate 10 is evenly distributed with mesh holes for filtering incoming materials. A rotating rod 6 is rotatably connected to the bottom surface of the filter screen plate 10. The rotating rod 6 extends to the outside of the mesh cover 3. The upper, middle and lower outer rings of the rotating rod 6 inside the mesh cover 3 are all equipped with sleeves 9. Three connecting plates 13 are evenly welded to the outer ring of each sleeve 9. A second cleaning plate 12 is installed on the side of the connecting plate 13 away from the sleeve 9. The side of the second cleaning plate 12 away from the connecting plate 13 is in close contact with the inner wall of the mesh cover 3. When the rotating rod 6 rotates, the second cleaning plate 12 can scrape off the debris attached to the inner wall of the mesh cover 3. A first cleaning plate 11 is installed on the upper part of the second cleaning plate 12. One side of the first cleaning plate 11 is in close contact with the outer surface of the filter screen plate 10 for removing debris clogging the mesh holes of the filter screen plate 10.

[0022] A blocking block 7 is provided at the bottom of the mesh cover 3. A rotating rod 6 passes through the blocking block 7. A rubber sealing ring is installed at the upper part of the rotating rod 6 where it passes through the blocking block 7 to prevent material from leaking into the blocking block 7 and to prevent material from entering the threaded tube 8 welded to the outer ring of the rotating rod 6. The lower outer ring of the rotating rod 6 is welded with the threaded tube 8. A limiting nut 4 matching the threaded tube 8 is provided on the outer ring of the rotating rod 6. Through the cooperation of the limiting nut 4 and the threaded tube 8, the blocking block 7 can be fixedly installed at the opening at the bottom of the mesh cover 3. A rotating plate 5 is installed at the bottom end of the rotating rod 6. Multiple... In actual use, when material enters the screen 3, it is initially filtered by the filter screen 10, and impurities are blocked outside. If impurities are attached to the inner wall of the screen 3 or the filter screen 10, the operator can first unscrew the limit nut 4 from the installation threaded pipe 8. At this time, the blockage block 7 can be removed from the screen 3. Then, the push rod 14 can be manually rotated to drive the rotating plate 5 and the rotating rod 6 to rotate, thereby causing the first cleaning plate 11 and the second cleaning plate 12 to clean the filter screen 10 and the inner wall of the screen 3 respectively. The impurities will be discharged through the opening at the bottom of the screen 3, thus ensuring the normal feeding of the sand pump.

[0023] Example 2: Please refer to Figures 1-4 The overall structure of the sand pump in this embodiment is basically the same as that in Embodiment 1, but some details have been optimized. The connecting flange between the sand pump body 1 and the feed pipe 2 adopts a specially designed sealing structure, which further enhances the sealing performance of the connection and prevents material leakage during the conveying process.

[0024] The mesh cover 3 is still spindle-shaped, but its surface roughness has been treated to make it smoother, reducing the friction between the material and the inner wall of the mesh cover 3 and reducing the material residue in the mesh cover 3. The filter screen 10 is also hollow frustum-shaped, but the shape and distribution of its mesh holes have been improved, and a more reasonable layout has been adopted to improve filtration efficiency and reduce the probability of debris clogging the mesh holes.

[0025] The rubber sealing ring at the point where the rotating rod 6 passes through the blockage block 7 is made of a new material, which has better wear resistance and sealing performance, extending the service life of the sealing ring. In addition, the rubber sealing ring has a certain degree of elasticity, which will not affect the movement of the blockage block 7 on the rotating rod 6. The mounting threaded tube 8 and the limiting nut 4 at the bottom of the rotating rod 6 have also been optimized. The thread design of the limiting nut 4 is more reasonable and the fit with the mounting threaded tube 8 is tighter, so that the blockage block 7 can be firmly installed on the mesh cover 3.

[0026] The number of push rods 14 on the rotating plate 5 is increased and their distribution is more even, which makes it easier for the operator to rotate the push rods 14 and also allows for a more even transmission of rotational force. This results in better cleaning of the filter screen 10 and the inner wall of the mesh cover 3 by the first cleaning plate 11 and the second cleaning plate 12. In actual operation, when it is necessary to clean debris, the operator only needs to gently rotate the push rod 14 to drive the rotating rod 6 to rotate, so that the cleaning plate can quickly and effectively clean debris and ensure the stable operation of the sand pump. At the same time, replaceable scrapers (not shown in the figure) can also be installed on the first cleaning plate 11 and the second cleaning plate 12. When the scrapers are worn, they can be easily replaced.

[0027] Implementation Results: By installing a screen cover 3 at one end of the feed pipe 2 at the output end of the sand pump body 1, and setting a filter screen plate 10 at the end of the feed pipe 2 located inside the screen cover 3, dual filtration of the material entering the sand pump is achieved. The screen cover 3 can initially block larger debris, while the filter screen plate 10 can further filter smaller debris, effectively preventing debris from entering the interior of the sand pump body 1. This avoids debris causing wear and blockage to the internal parts of the sand pump, thereby ensuring the stable operation of the sand pump, extending its service life, reducing equipment maintenance costs and downtime, and improving production efficiency.

[0028] When debris adheres to the inner wall of the screen cover 3 or the filter screen plate 10, the operator can first unscrew the limit nut 4 from the mounting threaded pipe 8. At this time, the blockage block 7 can be removed from the screen cover 3. Then, the push rod 14 can be manually rotated to drive the rotating plate 5 and the rotating rod 6 to rotate, thereby causing the first cleaning plate 11 and the second cleaning plate 12 to clean the filter screen plate 10 and the inner wall of the screen cover 3 respectively. The debris will be discharged through the opening at the bottom of the screen cover 3, thus ensuring the normal feeding of the sand pump. There is no need to stop the machine to disassemble the parts. The operation is simple and quick. This design can clean the debris in time, prevent the debris from clogging the mesh, ensure the filtration efficiency of the filter screen plate 10 and the screen cover 3, and enable the sand pump to feed and run continuously and stably.

[0029] 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.
