Description

Technical Field

[0001] This utility model relates to an impeller seat structure, and more particularly to a 304 stainless steel filter screen fully protected diversion impeller seat structure. Background Technology

[0002] When using impeller housing structures, the internal impeller components, lacking the protection of a filter screen, are often clogged by debris in the water, affecting the impeller's normal operation and flow calculation. Currently, some impeller housing structures use filters that only cover the bottom of the impeller to prevent debris from entering, but this is unsuitable for diversion-type impeller housing structures. Water flows back into the impeller from the diversion channel, carrying debris along with it, thus resolving the problem of debris entanglement in the water.

[0003] Therefore, how to fully protect the split-flow impeller seat structure has become a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a 304 stainless steel filter screen fully protected diversion impeller seat structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A 304 stainless steel filter screen fully protected flow-diverting impeller seat structure, the impeller seat structure includes an impeller seat body and a filter screen; a fixing protrusion ring is provided on the outside of the impeller seat body; the filter screen is fixed to the lower surface of the fixing protrusion ring by screws; the filter screen is provided with uniformly distributed filter holes.

[0007] Furthermore, the filter screen is made of 304 stainless steel.

[0008] Furthermore, the filter screen is a cylindrical structure with an opening at the top.

[0009] Furthermore, the impeller seat body is provided with a flow divider and a water inlet; the flow divider is provided with evenly distributed flow divider baffles; and the water inlet is provided with an impeller.

[0010] Furthermore, a sealing rubber ring is provided at the bottom of the filter screen.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model provides all-around protection by completely wrapping the bottom of the impeller seat structure with a filter screen, preventing debris from entering the impeller seat structure and causing blockage or jamming. Furthermore, the use of 304 stainless steel ensures that the filter screen will not rust or be damaged when immersed in water for a long time, guaranteeing the quality of filtration, providing comprehensive protection, and achieving good filtration effect.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] Example

[0024] like Figure 1 and 2 As shown, a 304 stainless steel filter screen fully protected flow-diverting impeller seat structure is disclosed. The impeller seat structure includes an impeller seat body 1 and a filter screen 2. The impeller seat body 1 is provided with a flow-diverting groove 5 and a water inlet groove 6. The flow-diverting groove 5 is provided with evenly distributed flow-diverting baffles 7 for water diversion. The number of flow-diverting baffles 7 installed controls the water flow rate, thereby adjusting the amount of water flowing through the water inlet groove 6 and reducing the impact force on the impeller. An impeller 8 is provided in the water inlet groove 6 for rotating under the impact of water to measure the water flow rate. A fixing ring 3 is provided on the outside of the impeller seat body 1. The filter screen 2... The filter screen 2 is fixed to the lower surface of the fixing ring 3 with screws, and completely covers the bottom of the impeller seat body 1, forming a fully enclosed structure for all-round protection. The filter screen 2 is provided with evenly distributed filter holes 4. The size of the filter holes 4 is such that only water and tiny substances can pass through, while larger debris cannot pass through, which can protect the impeller 8 from being entangled by debris and affecting its operation. The filter screen 2 is made of 304 stainless steel, which will not rust even after being soaked in water for a long time, and the filter holes 4 will not break due to rust, thus allowing debris to pass through. The filter screen 2 is a cylindrical structure with an open top.

[0025] To improve the sealing performance of the filter screen 2, a sealing rubber ring 9 is provided at the bottom of the filter screen 2, which can prevent some substances in the water from entering directly from the bottom of the filter screen 2. The water can only enter from the side filter holes 4, effectively blocking the debris.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
