Description

Technical Field

[0001] The utility model relates to the field of new energy, and in particular to an auxiliary structure for preventing blades from wearing out in a circulating water pump. Background Art

[0002] The operating principle of a circulating water pump is primarily based on the mechanics of an impeller. When the motor drives the impeller to rotate, it drives the liquid to rotate at high speed, transferring mechanical energy to the liquid. This rotational motion creates a pressure differential within the pump casing, forming a fluid flow that circulates the liquid. Impeller-type circulating water pumps use the continuously rotating impeller to draw liquid in through the inlet and accelerate it before discharging it through the outlet, achieving a circulating flow of liquid. Impeller-type circulating water pumps are widely used in various fields, including industry, medicine, and laboratories. In industry, they are widely used in the chemical, pharmaceutical, food, and electronics industries to transport liquids of various properties. In the medical field, circulating water pumps are used in medical devices such as heart support systems and artificial livers to ensure smooth and stable liquid circulation. In laboratories, circulating water pumps are used in equipment such as bioreactors and separation membranes to provide a stable liquid circulation environment for experiments. In actual use, debris in the water can flow with the water and enter the pump, where it comes into contact with the blades, causing friction and wear, reducing their service life.

[0003] For example, the description of the "Grinding Submersible Pump Capable of Cutting Foreign Matter" disclosed in Chinese utility model patent CN201420466909.1 discloses that the present invention has the following beneficial effects: According to the present invention, the impeller's cutting edge and the cutting housing work together to cut foreign matter, preventing damage to the pump body caused by the inflow of foreign matter, significantly enlarging the inflow hole, and thereby increasing the water output of the submersible pump. Furthermore, the connecting portions of the various components are provided with a first cutting head, a second cutting head, and a third cutting head. The interaction between the impeller and the cutting housing prevents wear while increasing cutting force. An expanded hole is formed at the inflow hole, increasing the flow rate into the pump body and improving the cutting effect on foreign matter. The cutting edge forms a spiral shape that gradually widens from the center of the impeller toward the blades, thereby increasing suction pressure and the flow rate of fluid into the pump body, while also preventing vortexes generated when the fluid is drawn in. However, this patent still fails to effectively address the aforementioned drawbacks.

[0004] Therefore, we have made improvements to this problem and proposed an auxiliary structure for anti-wear of circulating water pump blades. Summary of the Invention

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] Example 1

[0033] Please refer to Figure 1 and Figure 2 , a circulating water pump blade anti-wear auxiliary structure includes a connecting component 1, and a filter component 2 is rotatably provided at the front end of the connecting component 1. The filter component 2 can effectively prevent impurities, mud, floating objects, etc. in the water from entering the water pump, reducing the wear and blockage of the internal parts of the water pump, thereby protecting the water pump from damage. By reducing the erosion and wear of the impeller by impurities, the service life of the water pump can be extended and the cost of maintenance and replacement can be reduced. A cleaning component 3 and an impact component 4 are provided inside the connecting component 1. The impact component 4 is located behind the cleaning component 3. The connecting component 1, the filter component 2 and the cleaning component 3 cooperate to clean the debris stuck in the filter hole, avoiding the influence of the water inlet volume and water inlet pressure of the water pump due to the blockage of the filter hole, resulting in the decline of the water pump performance. The cleaning component 3 and the impact component 4 cooperate to further clean the debris stuck in the filter hole and with a high degree of jamming tightness through the vibration generated by continuous impact, thereby improving the cleaning effect.

[0034] Further, such as Figure 1 、 Figure 2 and Figure 4 As shown, the connecting assembly 1 includes a first steel ring 11 , a flange 12 is fixedly provided at the rear end of the first steel ring 11 , and an annular sliding groove is provided on the outer wall of the first steel ring 11 .

[0035] The provision of the flange 12 can facilitate the installation of the circulating water pump blade anti-wear auxiliary structure at the water inlet of the water pump.

[0036] Further, such as Figure 1 、 Figure 2 and Figure 4As shown, the filter assembly 2 includes a second steel ring 21 that is movably mounted on the front half of the first steel ring 11. A slip ring 26 is fixedly mounted on the inner wall of the rear end of the second steel ring 21. The slip ring 26 slides in the annular groove.

[0037] The second steel ring 21 is enabled to rotate.

[0038] Further, such as Figure 1 、 Figure 2 and Figure 4 As shown, the annular chute is filled with steel balls 27, and a support ring 13 is fixedly mounted on the first steel ring 11. The support ring 13 is located at the front side of the annular chute, and a hanging ring 22 is fixedly mounted on the outer wall of the second steel ring 21.

[0039] The support ring 13 supports the second steel ring 21. When the second steel ring 21 rotates, the slip ring 26 rotates in the annular groove, and the steel ball 27 reduces friction by rolling, making the second steel ring 21 rotate more smoothly. The design of the lifting ring 22 can facilitate the operator to manually drive the second steel ring 21 to rotate, and during the lifting function, it can provide a buckle point for the lifting rope.

[0040] Further, such as Figure 1 、 Figure 2 and Figure 3 As shown, the filter assembly 2 also includes a bolt 25, a filter screen 24 is provided on the front side of the second steel ring 21, a locking ring 23 is provided on the front side of the filter screen 24, and the bolt 25 passes through the locking ring 23, the filter screen 24 and the second steel ring 21 for threaded connection.

[0041] The filter screen 24 can effectively prevent impurities, sediment, floating objects, etc. in the water from entering the water pump, reducing the wear and blockage of the internal parts of the water pump, thereby protecting the water pump from damage. The locking ring 23 can protect the edge of the filter screen 24.

[0042] Example 2

[0043] The auxiliary structure for anti-wear of circulating water pump blades provided in Example 1 is further optimized. Specifically, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the cleaning assembly 3 includes a disc 33, a first support rod 31 is fixedly connected between the disc 33 and the inner wall of the first steel ring 11, and a cleaning brush 32 is fixedly provided on one side of the first support rod 31, and the cleaning brush 32 is in contact with the filter screen 24.

[0044] When the second steel ring 21 rotates, the filter screen 24 rotates synchronously with the second steel ring 21 . When the filter screen 24 rotates, the cleaning brush 32 remains stationary, and the cleaning brush 32 can clean the filter screen 24 in the rotating state.

[0045] Further, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the impact assembly 4 includes a sleeve 44, which is located behind the disc 33. A second support rod 41 is fixedly connected between the sleeve 44 and the inner wall of the first steel ring 11. A transmission rod 43 is movably sleeved in the sleeve 44. A driving block 42 is fixedly provided at the rear end of the transmission rod 43, and an impact head 47 is fixedly provided at the front end of the transmission rod 43.

[0046] By driving the transmission rod 43 to move along the axial direction of the first steel ring 11, the impact head 47 can impact the disc 33, and the impact force can be transmitted to the filter screen 24 through the disc 33. The vibration generated by continuous impact can further clean up the debris stuck in the filter hole with a high degree of tightness, thereby improving the cleaning effect.

[0047] Further, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the impact assembly 4 also includes a limiting ring 46 fixedly mounted on the transmission rod 43, and the limiting ring 46 is located behind the impact head 47. A coil spring 45 is movably mounted on the transmission rod 43, and the coil spring 45 is located between the sleeve 44 and the limiting ring 46.

[0048] The drive block 42 is manually controlled to move in a direction away from the filter screen 24, and the drive block 42 drives the transmission rod 43 to move in the same direction, and the coil spring 45 is forced to contract. After releasing the hand, the force forcing the coil spring 45 to contract disappears, and the coil spring 45 quickly rebounds, driving the transmission rod 43 to move in a direction close to the filter screen 24, causing the impact head 47 to hit the disc 33.

[0049] The use process of the circulating water pump blade anti-wear auxiliary structure provided by the utility model is as follows:

[0050] Before use, the circulating water pump blade anti-wear auxiliary structure must be installed at the water inlet of the water pump. When in use, water must pass through the filter screen 24 when entering the water pump. The filter screen 24 can effectively prevent impurities, sediment, floating objects, etc. in the water from entering the water pump, reducing the wear and blockage of the internal parts of the water pump, thereby protecting the water pump from damage. When maintaining the internal structure of the water pump, the circulating water pump blade anti-wear auxiliary structure is removed at the water inlet of the water pump to carry out maintenance work. When cleaning the filter screen 24, the operator manually drives the second steel ring 21 to rotate. When the second steel ring 21 rotates, the filter screen 24 follows the second steel ring 21. The ring 21 rotates synchronously. When the filter screen 24 rotates, the cleaning brush 32 remains stationary. The cleaning brush 32 can clean the filter screen 24 in the rotating state. The manual control driving block 42 moves in the direction away from the filter screen 24. The driving block 42 drives the transmission rod 43 to move in the same direction, and the coil spring 45 is forced to contract. After releasing the hand, the force forcing the coil spring 45 to contract disappears, and the coil spring 45 rebounds quickly, driving the transmission rod 43 to move in the direction close to the filter screen 24, causing the impact head 47 to hit the disc 33. The vibration generated by continuous impact further cleans the debris stuck in the filter hole and with a high degree of jamming, thereby improving the cleaning effect.
