Description

Technical Field

[0001] The present application relates to the technical field of swimming pool water circulation filtration, and in particular to a filtering device for swimming pool water circulation. Background Art

[0002] The health issues of swimming pool water are increasingly attracting the attention of consumers. As government agencies and swimming pool managers, it is necessary to satisfy consumers' right to know. Swimming pools, as a life carrier closely related to the quality of life, must meet the national quality and safety requirements.

[0003] Swimming pool water is generally not replaced, and it needs to be purified by using chemical precipitation and filtration mechanisms. The current filtration mechanism has a relatively simple structure and is generally installed on the pool water circulation pipe. It uses a filter element for filtration, but there are many impurities in the pool water. Directly using a filter element for filtration requires a large filter element cost, which not only has high maintenance costs, but also causes waste of resources.

[0004] Therefore, there is an urgent need to develop a filtering mechanism with good filtering effect and low cost. Utility Model Content

[0005] The purpose of the present application is to provide a filtering device for swimming pool water circulation to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present application provides a filtering device for swimming pool water circulation using the following technical solutions:

[0007] A filtering device for swimming pool water circulation, comprising a coarse filtering pool, a pressure storage pipe and a filtering mechanism which are connected in sequence, wherein a first baffle and a second baffle are arranged in the middle of the coarse filtering pool, and the coarse filtering pool is divided into a liquid inlet tank, a sedimentation tank and a liquid outlet tank by the first baffle and the second baffle, and the cross section of the pressure storage pipe is L-shaped, and one end of the pressure storage pipe is connected to the bottom of the liquid outlet tank;

[0008] The filtering mechanism comprises a fine filtering pool and a filtering assembly, wherein the filtering assembly is detachably installed in the fine filtering pool, the bottom of the fine filtering pool is connected to the pressure accumulator pipe, and the height of the horizontal plane where the coarse filtering pool is located is higher than the height of the horizontal plane where the filtering assembly is located.

[0009] The filter assembly includes an annular mounting seat and a filter element. The annular mounting seat includes an annular base. The annular base is fixed on the inner wall of the fine filter pool, and a sealing ring is connected between the annular base and the fine filter pool. A positioning tube is fixedly connected to the middle of the annular base, and a plurality of water outlet holes are opened on the surface of the positioning tube. The filter element is sleeved on the positioning tube, and a top cover is threadedly connected to the top of the positioning tube. The two ends of the filter element are respectively sealed and connected to the annular base and the top cover.

[0010] Preferably, a filter screen is fixed on the top of the coarse filtration tank.

[0011] By adopting the above technical solution, the filter screen can filter out larger impurities.

[0012] Preferably, a buffer plate is arranged in the liquid inlet groove, and a surface of the buffer plate has a plurality of inclined through grooves.

[0013] By adopting the above technical solution, the pool water hits the buffer plate, then flows to the bottom of the buffer plate through the inclined groove, and slowly overflows the entire liquid inlet tank. During this process, impurities with larger mass will settle to the bottom of the liquid inlet tank under the action of gravity, and the setting of the buffer plate can slow down the impact force of the water, thereby avoiding the lifting of the precipitated impurities.

[0014] The bottom walls of the liquid inlet tank and the sedimentation tank are both arranged as slopes converging toward the center, and are connected with a sewage pipe at the center point, and a valve is installed on the sewage pipe.

[0015] In order to better circulate water, a return pipe is connected to the side of the fine filtration tank, and the return pipe is arranged on the top of the annular base.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: the filtering device for swimming pool water circulation has a simple structure and a low manufacturing and use cost, but can achieve a good filtering effect. By providing a liquid inlet tank and a sedimentation tank, the gravity of the impurities themselves can be used to precipitate impurities with larger mass at the bottom of the tank. After two sedimentations, the swimming pool water carries impurities with smaller volume into the fine filtration tank and overflows from the bottom of the filter component. The filter element in the filter component can filter fine impurities, and the filtering effect is good. Under this structure, the filter element can have a longer service life, thereby greatly reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a filtering device for swimming pool water circulation, referring to Figure 1-3 , including a coarse filter tank 1, a pressure storage pipe 2 and a filtering mechanism connected in sequence, a first baffle and a second baffle are arranged in the middle of the coarse filter tank 1, and the coarse filter tank 1 is divided into a liquid inlet tank 11, a sedimentation tank 12 and a liquid outlet tank 13 by the first baffle and the second baffle. Specifically, in order to improve the water passing effect, the upper surface height of the first baffle is higher than the upper surface height of the second baffle. The cross section of the pressure storage pipe 2 is L-shaped, and one end of the pressure storage pipe 2 is connected to the bottom of the liquid outlet tank 13. The bottom walls of the liquid inlet tank 11 and the sedimentation tank 12 are both arranged with slopes converging toward the center, and a sewage pipe 14 is connected at the center point. A valve is installed on the sewage pipe 14, and sewage can be discharged regularly;

[0023] The filtering mechanism includes a fine filtering pool 31 and a filtering assembly. The filtering assembly is detachably installed in the fine filtering pool 31. The bottom of the fine filtering pool 31 is connected to the pressure accumulator pipe 2. The height of the horizontal plane where the coarse filtering pool 1 is located is higher than the height of the horizontal plane where the filtering assembly is located.

[0024] Reference Figure 2 and Figure 3 The filter assembly includes an annular mounting seat and a filter element 4. The annular mounting seat includes an annular base 321. The annular base 321 is fixed on the inner wall of the fine filter pool 31, and a sealing ring is connected between the annular base 321 and the fine filter pool 31. A positioning pipe 322 is fixedly connected to the middle of the annular base 321. A plurality of water outlet holes 3211 are opened on the surface of the positioning pipe 322. The filter element 4 is sleeved on the positioning pipe 322. The top of the positioning pipe 322 is threadedly connected with a top cover 323. Both ends of the filter element 4 are respectively sealed and connected to the annular base 321 and the top cover 323. The side of the fine filter pool 31 is connected with a return pipe 5, and the return pipe 5 is arranged on the top of the annular base 321.

[0025] Reference Figure 1-3 A filter screen 6 is fixed on the top of the coarse filtration tank 1. The setting of the filter screen 6 can filter out impurities with larger volume. Then the pool water enters the liquid inlet tank 11. A buffer plate 7 is arranged in the liquid inlet tank 11. The surface of the buffer plate 7 has a plurality of inclined through grooves 71. The pool water hits the buffer plate 7, and then flows to the bottom of the buffer plate 7 through the inclined through grooves 71, and slowly overflows the entire liquid inlet tank 11. In this process, impurities with larger mass will settle to the bottom of the liquid inlet tank 11 under the action of gravity, and the setting of the buffer plate 7 can slow down the impact force of the water, thereby avoiding lifting up the precipitated impurities.

[0026] The implementation principle of a filtering device for swimming pool water circulation in the embodiment of the present application is as follows:

[0027] The pool water enters the liquid inlet tank 11 and impacts the buffer plate 7, then flows to the bottom of the buffer plate 7 through the inclined through groove 71, and slowly overflows the entire liquid inlet tank 11. In this process, impurities with larger mass will settle to the bottom of the liquid inlet tank 11 under the action of gravity, and the pool water that has been initially precipitated will overflow into the sedimentation tank 12, and overflow from the sedimentation tank 12 to the liquid outlet tank 13. During the pool process, when the pool water is in the sedimentation tank 12, impurities with larger mass will also settle to the bottom of the sedimentation tank 12 under the action of gravity. After two sedimentations, the swimming pool water carries smaller impurities into the liquid outlet tank 13, and enters the fine filtration tank 31 through the pressure accumulator pipe 2, and overflows from the bottom of the filter component. The filter element 4 in the filter component can filter fine impurities, and the filtration effect is better.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
