Description

Technical Field

[0001] This utility model relates to the field of single screw pump technology, specifically to an anti-clogging single screw pump. Background Technology

[0002] In the field of industrial fluid transportation, single screw pumps are widely used due to their advantages such as good self-priming ability and ability to transport high-viscosity media. For example, single screw pumps play a vital role in industries such as petrochemicals, sewage treatment, and food and beverage.

[0003] In actual operation, the medium being transported often contains various impurities. Once these impurities enter the single screw pump, they easily accumulate in the gap between the pump's screw and stator, leading to reduced flow rate, unstable pressure, and even pump damage, severely affecting the pump's normal operation and service life. Therefore, we propose an anti-clogging single screw pump. Utility Model Content

[0004] The purpose of this invention is to provide a clog-resistant single screw pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a single screw pump for preventing clogging, comprising a single screw pump body, an inlet pipe installed at the inlet end of the single screw pump body, a connecting cylinder installed at the top end of the inlet pipe, two mounting blocks installed on the surface of the connecting cylinder, insertion holes opened on the surface of the mounting blocks, a through hole opened on one side of the connecting cylinder, and a cover plate for sealing the through hole installed on the surface of the connecting cylinder;

[0006] A rotating rod is rotatably mounted inside the connecting cylinder. A limiting component that passes through the insertion hole is mounted on the surface of the rotating rod. A connecting rod is fixedly mounted on the outside of the rotating rod. A filter cover is mounted on one side of the connecting rod. A blocking component is provided on the inside of the filter cover.

[0007] Preferably, the cover plate is bolted to the surface of the connecting cylinder, and a sealing gasket is installed between the cover plate and the connecting cylinder.

[0008] Preferably, one end of the rotating rod movably passes through the connecting cylinder, and there is a dynamic seal between the rotating rod and the connecting cylinder.

[0009] Preferably, the limiting component includes a sliding insert rod, which is slidably installed inside the rotating rod. A baffle is fixedly installed at one end of the sliding insert rod, and a spring is installed on one side of the baffle. The end of the spring away from the baffle is installed on the outside of the rotating rod, and the sliding insert rod passes through the insertion hole.

[0010] Preferably, the cross-sectional dimensions of the sliding insert are matched with those of the insertion hole.

[0011] Preferably, the blocking assembly includes a barrier net and a handle. The barrier net is disposed at the bottom inside the filter cover, the handle is installed on one side of the barrier net, and a plurality of abutment rods are installed on the outside of the handle to abut against the inside of the filter cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this anti-clogging single screw pump, the medium enters the connecting cylinder through the pipe at the top of the connecting cylinder, and then enters the inlet pipe for transportation. The filter cover and screen can intercept larger particulate impurities in the medium, preventing large particulate impurities from entering the single screw pump body and clogging it, thus achieving the anti-clogging effect.

[0014] 2. This anti-clogging single screw pump, by pulling the baffle, causes the sliding rod to move and disengage from one insertion hole. By rotating the rotating rod, the sliding rod is rotated, causing it to face into another insertion hole. The baffle pushes the sliding rod into the insertion hole. During this process, the rotating rod drives the connecting rod and filter cover to rotate and face the through hole. By removing the bolts, the cover plate can be removed. Then, by pulling out the handle, the stop rod, and the screen, it is easy to clean the screen and the surface of the filter cover, thus preventing excessive large particles of impurities from clogging the filter cover and screen. The cleaning is relatively convenient and does not require opening the entire pump body for cleaning. Attached Figure Description

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

[0021] Please refer to Figure 1-3 As shown, this utility model provides a single screw pump that is not clogged, including a single screw pump body 1, an inlet pipe 2 installed at the inlet end of the single screw pump body 1, a connecting cylinder 3 installed at the top end of the inlet pipe 2, two mounting blocks 4 installed on the surface of the connecting cylinder 3, insertion holes 5 opened on the surface of the mounting blocks 4, a through hole 6 opened on one side of the connecting cylinder 3, and a cover plate 7 for sealing the through hole 6 installed on the surface of the connecting cylinder 3.

[0022] A rotating rod 8 is rotatably installed inside the connecting cylinder 3. One end of the rotating rod 8 movably passes through the connecting cylinder 3, and there is a dynamic seal between the rotating rod 8 and the connecting cylinder 3. A limiting component that passes through the insertion hole 5 is installed on the surface of the rotating rod 8. A connecting rod 9 is fixedly installed on the outside of the rotating rod 8. A filter cover 10 is installed on one side of the connecting rod 9. A blocking component is provided on the inside of the filter cover 10.

[0023] Specifically, the medium enters the connecting cylinder 3 through the pipe at the top of the connecting cylinder 3, and then enters the inlet pipe 2 for transportation. The filter cover 10 and the screen 11 can intercept larger particulate impurities in the medium, preventing large particulate impurities from entering the single screw pump body 1 and clogging it, thus achieving an anti-clogging effect.

[0024] The cover plate 7 is installed on the surface of the connecting cylinder 3 by bolts. A sealing gasket is installed between the cover plate 7 and the connecting cylinder 3. By unscrewing the bolts, the cover plate 7 can be easily disassembled to clean the filter cover 10.

[0025] The limiting component includes a sliding rod 14, which is slidably installed inside the rotating rod 8. A baffle 15 is fixedly installed at one end of the sliding rod 14, and a spring 16 is installed on one side of the baffle 15. The end of the spring 16 away from the baffle 15 is installed on the outside of the rotating rod 8. The sliding rod 14 passes through the insertion hole 5, and the cross-sectional dimensions of the sliding rod 14 match those of the insertion hole 5. By pulling the baffle 15, the sliding rod 14 moves and disengages from one of the insertion holes 5, at which point the rotating rod 8 can rotate normally. By controlling the sliding rod 14 to insert into the insertion hole 5, the rotating rod 8 cannot rotate.

[0026] The blocking assembly includes a net 11 and a handle 12. The net 11 is located at the bottom inside the filter cover 10, and the handle 12 is installed on one side of the net 11. Multiple abutments 13 that abut against the inside of the filter cover 10 are installed on the outside of the handle 12. The surface of the net 11 can hold large impurities. Since it can be removed for cleaning, the difficulty of cleaning impurities on the surface of the filter cover 10 is reduced.

[0027] Working principle: This utility model is a single screw pump that is not clogged. When in use, the medium enters the connecting cylinder 3 through the pipe at the top of the connecting cylinder 3, and then enters the inlet pipe 2 for transportation. The filter cover 10 and the screen 11 can intercept larger particles of impurities in the medium, preventing large particles of impurities from entering the single screw pump body 1 and clogging the single screw pump body 1, thereby achieving the anti-clogging effect.

[0028] By pulling the baffle 15, the sliding rod 14 moves and disengages from one of the insertion holes 5. By rotating the rotating rod 8, the sliding rod 14 is rotated, causing it to face into another insertion hole 5. The baffle 15 is then used to push the sliding rod 14 into the insertion hole 5. During this process, the rotating rod 8 drives the connecting rod 9 and the filter cover 10 to rotate and face the through hole 6. By removing the bolts, the cover plate 7 can be removed. Then, by pulling out the handle 12, the stop rod 13, and the screen 11, it is easy to clean the surface of the screen 11 and the filter cover 10, thereby preventing excessive large particles of impurities from clogging the filter cover 10 and the screen 11. The cleaning is relatively convenient, as the surface of the screen 11 can intercept a lot of impurities, and it can be removed for cleaning, making the cleaning work relatively convenient.
