Description

Technical Field

[0001] This utility model relates to the field of circulating pump technology, specifically to a high-efficiency and energy-saving circulating pump. Background Technology

[0002] Circulating pumps are widely used in various industrial and civil facilities. Their function is to circulate liquids to meet different process requirements or maintain the normal operation of the system. As an important component of the circulating pump, the inlet filter effectively intercepts impurities in the water, preventing them from entering the pump body. This protects critical components such as the impeller and seals, avoids equipment failure caused by wear from impurities, and extends the service life of the circulating pump.

[0003] However, traditional circulating pump inlet filters currently present numerous problems in practical use. Firstly, as circulating water is continuously filtered, a large amount of impurities gradually accumulates on the filter, leading to clogging, reduced water flow, and consequently, decreased pump efficiency, affecting the normal operation of the entire system. Secondly, when the filter becomes clogged, it often requires regular manual cleaning. Manual cleaning not only consumes significant manpower but also necessitates pausing the circulating pump, causing system interruptions, disrupting production or usage continuity, and resulting in additional economic losses. Furthermore, the effectiveness of manual cleaning is uncertain, potentially leading to incomplete cleaning and preventing the filter from fully recovering its performance. In addition, frequent manual cleaning increases labor intensity and places certain demands on the skills and experience of the operators.

[0004] Therefore, there is an urgent practical need to develop a device that can automatically clean the inlet filter screen of a circulating pump. Utility Model Content

[0005] To address the aforementioned problems, this invention presents a high-efficiency and energy-saving circulating pump.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A high-efficiency and energy-saving circulating pump includes a cylinder, an inlet pipe on the top wall of the cylinder, a drain pipe on the bottom wall of the cylinder, a filter cylinder embedded inside the cylinder, the outer walls of the left and right sides of the filter cylinder being fixedly connected to the inner walls of the left and right sides of the cylinder via round seats, a drain pipe on the right side wall of the cylinder, and a self-cleaning mechanism on the left side wall of the cylinder.

[0008] Furthermore, the self-cleaning mechanism includes a housing, a motor is provided on the left side wall of the housing, a connecting pipe is provided on the top wall of the housing, and round rods are rotatably connected to the inner walls of the left and right sides of the housing through sealed bearings. The left end of the round rods is fixedly connected to the output end of the motor through a coupling. A through hole communicating with the inner cavity is provided through the outer wall of the round rods. The right end of the round rods passes through a round seat and extends into the filter cartridge. A rotating rod is provided on the right end wall of the round rods, and multiple drainage holes are provided through the outer wall of the rotating rods.

[0009] Furthermore, the outer wall of the circular rod is in disconnected contact with the inner wall of the circular seat.

[0010] Furthermore, the connecting pipe, housing, round rod, and rotating rod are interconnected.

[0011] Furthermore, the drain holes are arranged in a circumferentially spaced pattern on the outer wall of the rotating rod.

[0012] The beneficial effects of this utility model are:

[0013] This self-cleaning device effectively reduces labor costs, eliminates the need for frequent manual cleaning, reduces reliance on operators, avoids the skill and experience requirements of manual cleaning, and also eliminates the additional economic losses caused by stopping the operation of the circulation pump due to manual cleaning, thus ensuring the continuity of production or use.

[0014] This device effectively filters the circulating water at the front end of the circulating pump, which can remove impurities in the water in a timely manner, prevent impurities from entering the pump body, protect key components such as impellers and seals, reduce equipment failures caused by wear due to impurities, thereby extending the service life of the circulating pump and improving the operational stability of the entire system.

[0015] The cleaning water sprayed from the drain hole thoroughly rinses the impurities on the outer wall of the filter cartridge. Compared with the potential for incomplete cleaning by manual cleaning, this self-cleaning device ensures that the filter cartridge is cleaned more thoroughly, allowing the filter screen performance to be better restored, thereby ensuring the efficient operation of the circulation pump and maintaining the normal operation of the system.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-2 As shown, a high-efficiency and energy-saving circulating pump includes a cylinder 1, an inlet pipe 2 on the top wall of the cylinder 1, a drain pipe 3 on the bottom wall of the cylinder 1, a filter cylinder 5 embedded inside the cylinder 1, the outer walls of the left and right sides of the filter cylinder 5 being fixedly connected to the inner walls of the left and right sides of the cylinder 1 via round seats 4, a drain pipe 6 on the right side wall of the cylinder 1, and a self-cleaning mechanism on the left side wall of the cylinder 1.

[0023] Furthermore, the self-cleaning mechanism includes a housing 7, a motor 8 on the left side wall of the housing 7, a connecting pipe 9 on the top wall of the housing 7, and round rods 10 rotatably connected to the inner walls of the left and right sides of the housing 7 via sealed bearings. The left end of the round rods 10 is fixedly connected to the output end of the motor 8 via a coupling. A through hole 11 communicating with the inner cavity is opened through the outer wall of the round rods 10. The right end of the round rods 10 passes through the round seat 4 and extends into the filter cartridge 5. A rotating rod 12 is provided on the right end wall of the round rods 10. Multiple drain holes 13 are opened through the outer wall of the rotating rods 12. Pressurized cleaning water is injected into the housing 7 through the connecting pipe 9, enters the round rods 10 and rotating rods 12 through the through hole 11, and is sprayed out through the drain holes 13. The cleaning water sprayed out through the drain holes 13 is sprayed from the inside to the outside of the filter cartridge 5, washing away the impurities on the outer wall of the filter cartridge 5.

[0024] Furthermore, the outer wall of the round rod 10 is disconnected from the inner wall of the round seat 4. After the motor 8 is started, the round rod 10 drives the rotating rod 12 and the drain hole 13 to rotate, so that the rotating rod 12 and the drain hole 13 can rotate in a circular motion inside the filter cylinder 5.

[0025] Furthermore, the connecting pipe 9, the housing 7, the round rod 10, and the rotating rod 12 are connected. Pressurized cleaning water is injected into the housing 7 through the connecting pipe 9, enters the round rod 10 and the rotating rod 12 through the through hole 11, and is sprayed out through the drain hole 13. The cleaning water sprayed out through the drain hole 13 is sprayed from the inside to the outside of the filter cylinder 5, which facilitates the washing away of impurities on the outer wall of the filter cylinder 5.

[0026] Furthermore, the drain holes 13 are arranged in a circular gap on the outer wall of the rotating rod 12. After the motor 8 is started, the round rod 10 drives the rotating rod 12 and the drain holes 13 to rotate. The rotating rod 12 and the drain holes 13 rotate in a circular motion inside the filter cylinder 5, so that the drain holes 13 can cover the inner wall surface of the filter cylinder 5. The cleaning water sprayed through the drain holes 13 thoroughly washes and cleans the impurities on the outer wall of the filter cylinder 5.

[0027] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0028] One specific application of this embodiment is:

[0029] In actual use, the filtration operation of circulating water is achieved through a rigorous and efficient process. Circulating water flows smoothly into the cylinder 1 through the inlet pipe 2. At this time, the filter cylinder 5 begins to play a key role. It is like a precise checkpoint, which filters the circulating water carefully. Impurities in the water are intercepted on the outer wall of the filter cylinder 5, while the purified circulating water passes smoothly through the round seat 4 and is then accurately delivered to the circulating pump through the drain pipe 6. This achieves efficient filtration of circulating water at the front end of the circulating pump, providing a reliable guarantee for the stable operation of the circulating pump.

[0030] When the filter cartridge 5 needs to be self-cleaned, the entire system will operate in an orderly manner according to specific steps. First, the operator turns off the circulation pump to avoid unnecessary impact on the circulation pump during the cleaning process. Then, the pressurized cleaning water is injected into the housing 7 through the connecting pipe 9 at a certain pressure. Driven by the pressure, the cleaning water follows the preset path and enters the round rod 10 quickly and accurately through the through hole 11, and then flows into the rotating rod 12. Subsequently, the cleaning water is sprayed out at high speed from the evenly distributed drain holes 13 on the rotating rod 12. This cleaning water is powerfully sprayed from the inside to the outside of the filter cartridge 5, instantly forming a strong impact on the impurities accumulated on the outer wall of the filter cartridge 5, and initially washing and loosening the impurities from the outer wall of the filter cartridge 5.

[0031] At the same time, motor 8 starts, and the output shaft of the motor is firmly connected to the round rod 10. The torque generated by the motor is transmitted to the round rod 10, causing the round rod 10 to drive the rotating rod 12 and the drain hole 13 to start rotating in a circular motion. During the rotation, the drain hole 13 moves continuously in a circular trajectory inside the filter cylinder 5, ensuring that it can fully cover the inner wall surface of the filter cylinder 5. In this way, the cleaning water sprayed from the drain hole 13 can more thoroughly and meticulously wash and clean the impurities on the outer wall of the filter cylinder 5, leaving no corner where impurities accumulate. After the powerful washing of the cleaning water, the impurities are separated from the outer wall of the filter cylinder 5 and form sewage with the water flow. This sewage is finally discharged in an orderly manner through the drain pipe 3. Thus, a complete self-cleaning operation of the filter cylinder 5 is completed. The entire self-cleaning process is highly automated and easy to operate, which greatly improves the cleaning efficiency and effect of the filter cylinder 5.

[0032] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
