Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to an anti-blocking submersible pump. Background Technique

[0002] A submersible pump is a pump that can work completely immersed in liquid. Its motor and pump body are usually designed as one, and the working part of the pump is directly placed in the liquid. This design makes the submersible pump suitable for handling various liquids, including those scenarios that require long-term work in liquid, such as in industries like sewage treatment, chemical processing or mining. Submersible pumps are often used to handle liquids containing solid particles, such as sewage or slurry. These solid particles may accumulate in the pump, causing the flow channel of the pump to be blocked, affecting the normal operation of the pump. If the pump is often blocked, it needs to be maintained and cleaned frequently, which will increase the maintenance cost and downtime. An anti-blocking design can reduce this situation and improve the operation efficiency and reliability of the pump. Blockage will cause the flow rate and head of the pump to decrease, thereby affecting the overall efficiency of the system. Through an anti-blocking design, it can be ensured that the submersible pump maintains a high working efficiency during the processing. A good anti-blocking design can reduce the wear of the pump body and internal components and extend the service life of the pump.

[0003] After the submersible pump is produced, it usually exists in a fixed form, which means that the length and design parameters of its pump body are fixed. In practical applications, the submersible pump may need to work in different scenarios and environments, and these scenarios may involve different liquid depths, flow requirements and operating conditions. However, a submersible pump with a fixed length is often difficult to adapt to these diverse usage requirements. Specifically, this fixed length limits the adjustment ability of the pump body, so that when facing changes in liquid level or scenarios that require pumping into different depths, the usage effect and efficiency of the pump may be affected. In addition, different application scenarios may have different requirements for the inlet and outlet positions, installation methods, etc. of the pump, and the fixed length design may not be able to meet these requirements, resulting in inconvenience in use.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2, An embodiment provided by the present utility model: An anti-blocking submersible pump, which includes an output motor 1. A upper pipe body 5 is fixedly arranged at the lower end of the output motor 1. A telescopic pipe 13 is fixedly arranged at the lower end of the upper pipe body 5. A lower pipe body 11 is fixedly arranged at the lower end of the telescopic pipe 13. An impeller assembly 7 is fixedly arranged at the lower end of the lower pipe body 11. A filter seat 9 is fixedly arranged at the lower end of the impeller assembly 7. A sealing plate 16 is fixedly arranged at the lower end of the filter seat 9. A plurality of filter holes 8 are formed on the outer surface of the filter seat 9.

[0026] The output end of the impeller assembly 7 is fixedly connected with a liquid outlet pipe 15. The upper end of the liquid outlet pipe 15 penetrates and is arranged inside the positioning hole 14. The upper part of the rod body of the threaded rod 17 is threadedly sleeved inside the threaded hole 4. A hand wheel 2 is fixedly arranged at the upper end of the threaded rod 17. The telescopic pipe 13 is made of stainless steel material. The liquid outlet pipe 15 and the threaded rod 17 are parallel to each other.

[0027] The output end of the output motor 1 is fixedly provided with a rotating rod. The lower end of the rotating rod is connected with the impeller inside the impeller assembly 7. The rotating rod is fixedly sleeved inside the upper pipe body 5 and the lower pipe body 11 through bearings respectively. The rotating rod located inside the telescopic pipe 13 can be telescopic.

[0028] Specifically, in actual application, the submersible pump may need to adapt to different liquid depths and operating environments, while traditional submersible pumps with fixed lengths often struggle to meet these diverse requirements. The present utility model provides a design with a telescopic function. By setting an adjustment mechanism between the upper support plate 3 and the lower support plate 12, users can conveniently adjust the height of the submersible pump, enabling the pump body to adapt to liquids at different depths. This flexible adjustment function greatly enhances the applicability of the submersible pump, allowing it to be used in a variety of environments and meet different operating needs. Specifically, by rotating the threaded rod 17 and the hand wheel 2, the distance between the upper support plate 3 and the lower support plate 12 can be precisely adjusted, thereby adjusting the overall height of the submersible pump. The use of the telescopic pipe 13 not only ensures the strength and durability of the pump body but also enables the pump body to flexibly expand and contract within different depth ranges, further enhancing the operational convenience of the device. This design demonstrates extremely high efficiency and adaptability when faced with liquid level changes or when dealing with liquids at different levels, thus meeting the usage requirements in different scenarios and avoiding problems such as reduced efficiency or inconvenience caused by an inappropriate pump body length.

[0029] Refer to Figure 3 、 Figure 4 , An upper support plate 3 is fixedly sleeved at the upper part of the pipe body of the upper pipe body 5. A positioning hole 14 and a threaded hole 4 are respectively formed on both sides of the upper end surface of the upper support plate 3. A lower support plate 12 is fixedly sleeved at the upper part of the pipe body of the lower pipe body 11. A rod seat 6 is rotatably arranged on one side of the upper end surface of the lower support plate 12 away from the telescopic pipe 13. A threaded rod 17 is fixedly arranged at the upper end of the rod seat 6.

[0030] A C-shaped support frame 10 is fixedly sleeved on the lower end of the pipe body of the lower pipe body 11. The lower end of the C-shaped support frame 10 is located at the lower end of the filter base 9, and the lower end of the C-shaped support frame 10 is longer than the upper end.

[0031] Specifically, the anti-blocking design is a crucial function when the submersible pump is dealing with liquids containing solid particles. During the use of a conventional submersible pump, if the solid particles are large or in large quantities, they are likely to accumulate at the pump inlet or in the internal channels, resulting in the blockage of the pump flow passage, thus affecting the normal operation of the pump. Blockage not only reduces the flow rate and head of the pump, affecting the efficiency of the entire system, but may also cause the equipment to stop frequently, increasing the frequency of maintenance and cleaning, and thus raising the operating cost. The anti-blocking submersible pump of the present utility model is in contact with the liquid ground through the C-shaped support frame 10, so that the filter base 9 floats in the liquid instead of directly contacting the bottom of the liquid. This design reduces the possibility of large particle impurities entering the pump before startup, thus effectively preventing blockage. In addition, a plurality of filter holes 8 are provided on the filter base 9. These holes not only improve the filtering efficiency but also further prevent impurities from entering the pump body, ensuring that the pump can operate stably for a long time. Through these anti-blocking measures, the submersible pump not only reduces the maintenance cost but also improves the reliability and service life of the equipment.

[0032] Working principle: When in use, by rotating the handwheel 2, the threaded rod 17 rotates. The rotation of the threaded rod 17 can adjust the distance between the upper support plate 3 and the lower support plate 12, thereby realizing the telescoping of the telescopic pipe 13 and adjusting the overall height of the equipment, making the equipment applicable to various environments and more convenient to use;

[0033] Secondly, the filter base 9 of the equipment does not directly contact the liquid ground, but is supported by contacting the bottom of the liquid through the C-shaped support frame 10, which is used to improve efficiency and increases the occurrence of blockage.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
