[0001] This utility model relates to the field of water pump technology, specifically a circulating water pump. Background Technology

[0002] Water pumps are widely used in various liquid transportation fields, especially in industry, agriculture, urban water supply, drainage, and sewage treatment. Their core function is to transport liquids from one place to another. However, in actual use, traditional water pumps have some performance problems and limitations, such as low water flow driving efficiency, high energy loss, easy blockage by impurities, and decreased pumping efficiency over time. These problems not only affect the operational stability of the water pump but also increase energy consumption and maintenance costs.

[0003] Specifically, existing water pumps often suffer from the following technical defects:

[0004] Uneven water flow driving force: In traditional water pumps, the fit between the impeller and the pump body wall often leads to uneven distribution of water flow driving force, affecting pumping efficiency. Furthermore, as impurities enter, it may cause blockage or increased resistance.

[0005] Low energy efficiency: Water pump drive systems often suffer from low transmission efficiency and significant energy loss. This is especially true when the drive shaft and impeller are not precisely matched, leading to power transmission losses and reducing the overall efficiency of the water pump.

[0006] Impurities and interference: During the operation of a water pump, impurities and particulate matter in the liquid may interfere with the operation of the pump, causing poor water flow or blockage, thereby affecting the pumping effect and the service life of the equipment.

[0007] In view of this, we will study and improve the existing problems to provide a circulating water pump to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following is in conjunction with the appendix Figures 1-5 This invention describes a circulating water pump provided by some embodiments of the present invention. Example 1

[0028] This embodiment provides a circulating water pump, employing the structural scheme shown in the attached figure. The pump structure includes a main pump housing 100, a drive shaft assembly 200, and a paddle plate 300. The main pump housing 100 is an integrated container structure with an inlet port 110 and an outlet port 120 on its inner wall, and filter boxes 130 on both sides. The filter boxes 130 contain multiple filter layers, including coarse and fine filter layers, used to filter impurities in the water, ensuring clean and unobstructed water flow into the pump.

[0029] The main pump box 100 is provided with an inlet port 110 and an outlet port 120 on both sides. The inlet port 110 is used to introduce water flow, and the outlet port 120 is used to discharge the treated water flow.

[0030] The inner wall of the main pump box 100 is precisely designed to create an effective water flow propulsion force through sliding contact with the paddle plate 300. The spacious interior of the main pump box allows the paddle plate 300 to rotate freely, thus propelling the water flow.

[0031] The drive shaft assembly 200 consists of a motor 210 and a shaft disk 220 connected to the output end of the motor. The motor 210 serves as a power source, transmitting power to the paddle plate 300 via the shaft disk 220. The surface of the shaft disk 220 is provided with multiple lugs 221 for connecting to the paddle plate 300 and ensuring stable rotation of the paddle plate under the drive of the motor; the lugs 221 are evenly distributed circumferentially on the surface of the shaft disk 220 and are movably connected to the surface of the paddle plate 300.

[0032] Since the drive shaft assembly 200 adopts an eccentric arrangement and is combined with the adjustment structure 140, which is a screw structure, the working efficiency of the water pump can be adjusted by adjusting the eccentricity to adapt to different working requirements.

[0033] The paddle plate 300 has an arc-shaped curved structure and slides in contact with the inner wall of the main pump box. The paddle plate 300 slides against the inner side of the main pump box 100 through the sliding roller strip 310, forming an effective water flow driving force. When the paddle plate 300 rotates, it can push water into the water pump and discharge it through the outlet port 120; the other end of the paddle plate 300 is provided with a sliding roller strip 310 for sliding against the inner side of the main pump box 100; the paddle plate 300 has an arc-shaped curved structure, and the end of the paddle plate 300 slides against the inner side of the main pump box 100 through the sliding roller strip 310; the sliding roller strip 310 has a cylindrical rod structure and is made of polytetrachloroethylene.

[0034] A deformable conveying cavity is formed between the 300mm paddle plates, effectively preventing the accumulation and blockage of impurities. The arc-shaped design of the paddle plates ensures smooth water flow and enhances the pump's conveying capacity.

[0035] The filter cartridge 130 has a built-in filter layer for filtering large and fine particles in the water. The design of the filter cartridge ensures that the water at the inlet is fully filtered before entering the water pump, preventing impurities from entering the pump body and reducing wear and clogging of internal pump components. The filter cartridge 130 has a multi-layered filter layer, including a coarse filter layer and a fine filter layer.

[0036] The adjusting structure 140 adopts a screw structure, which, together with the eccentrically arranged drive shaft assembly 200, is used to adjust the contact mode between the impeller 300 and the inner wall of the main pump box, thereby further optimizing the working efficiency and conveying effect of the water pump. Example 2

[0037] In another embodiment, the main structural design of the pump remains unchanged, but the size of the pump can be adjusted according to different application requirements. For example, the main pump box 100 and the impeller 300 can be expanded or reduced according to the flow rate requirements of the liquid to meet the pumping requirements under different operating conditions. At the same time, the regulating structure 140 can also be designed as an electric regulating device, which uses sensors and intelligent control systems to automatically adjust the eccentricity according to the pumping flow rate and pressure, further improving the automation level of the pump. Example 3

[0038] Furthermore, the paddle plate 300 and the slide roller strip 310 can be made of different material combinations to adapt to pumping different liquid properties. For example, for liquids with high viscosity or containing more particles, the paddle plate 300 can be made of wear-resistant and corrosion-resistant materials to ensure long-term stable operation of the pump; while the slide roller strip 310 can be made of polytetrachloroethylene (PTFE) to reduce friction and improve durability.

[0039] Working principle and usage process of this utility model:

[0040] The motor 210 in the drive shaft assembly 200 provides power, which is transmitted to the paddle plate 300 through the shaft disc 220. The sliding contact between the paddle plate 300 and the inner wall of the main pump box 100 creates a water flow driving force, which pushes the water flow into the main pump box 100 and discharges it through the outlet port 120.

[0041] Because the impeller plate 300 has an arc-shaped curved structure, during the contact between the impeller plate and the inner wall of the main pump box, a deformable conveying cavity is formed between adjacent impeller plates. The deflection effect and sliding contact effect of the impeller plate 300 effectively avoid the accumulation and blockage of impurities, ensuring that the water pump can work continuously and stably.

[0042] The drive shaft assembly 200 adopts an eccentric arrangement, combined with the adjustment structure 140, to make the fit between the shaft disc 220 and the impeller 300 more precise. By adjusting the eccentricity, the pump's delivery efficiency can be adjusted according to actual needs, ensuring optimal performance under different operating conditions.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
