Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a filtering and purifying device for a water conservancy pipeline comprises a main body 1, a cover body 2 and a base 3 are fixedly connected to the upper end and the lower end of the main body 1 respectively, a filter cartridge 4 is rotatably arranged in the main body 1, an impeller 5 extending into the cover body 2 is fixedly connected to the upper end of the filter cartridge 4, the filter cartridge 4 can rotate in the same direction with the impeller 5 under the driving of the impeller 5, a cavity 6 is formed in the cover body 2, a primary bearing 7 sleeved with the impeller 5 is fixedly arranged in the cavity 6, an inner tube 8 extending into the filter cartridge 4 is fixedly sleeved at the upper end of the base 3, a secondary bearing 9 is fixedly sleeved on the inner tube 8, a connecting tube 10 sleeved with the secondary bearing 9 is integrally connected to the lower end of the filter cartridge 4, it is noted that the connecting tube 10 rotates through the secondary bearing 9 with the inner tube 8 as a lower fulcrum, which is helpful to ensure the integral stability of the filter cartridge 4, be connected with the inlet tube 11 corresponding with impeller 5 on the main part 1, and be connected with drain pipe 12 and blow off pipe 13 on base 3 and the main part 1 respectively, install valve 14 on the blow off pipe 13, carry out the in-process of water delivery through the device and set for the normal close state with blow off pipe 13 through valve 14, when needs clear up the impurity in the main part 1, block drain pipe 12 simultaneously through opening valve 14 on the blow off pipe 13 for the rubbish that lies in straining a section of thick bamboo 4 in the main part 1 is along with rivers from blow off pipe 13 outwards discharge.

Referring to the accompanying drawing 2, the filter cartridge 4 is a metal cylinder structure with a plurality of sieve holes on the side wall, the filter cartridge 4 is vertically arranged in the main body 1, and the filter cartridge 4 stirs the water in the main body 1 in the rotating process, so that the clean water enters the filter cartridge 4, and the impurities with large volume are trapped outside the filter cartridge 4.

The inner tube 8 is vertically disposed to facilitate nesting of the secondary bearing 9 in the connection in a vertically corresponding orientation to provide rotatable support for the filter cartridge 4.

It is worth noting that: the sealing gasket abutted against the primary bearing 7 is sleeved at the upper end of the impeller 5, and the sealing gasket abutted against the secondary bearing 9 is fixedly sleeved at the upper end and the lower end of the inner pipe 8 so as to ensure that water cannot leak outwards through the through hole of the inner pipe 8 in the filter cartridge 4 and the connecting pipe 10, thereby ensuring that water source in the filter cartridge 4 only flows into the base 3 through the inner pipe 8.

The inner pipe 8 extends to the upper end of the filter cartridge 4 and penetrates the lower end of the main body 1 and the connection pipe 10 in sequence.

The primary bearing 7 and the secondary bearing 9 are both air bearings. It is worth mentioning that: air bearings refer to sliding bearings that use a gas (usually air, but other gases are possible) as a lubricant. Air is less viscous than oil, is resistant to high temperatures, is pollution-free, and is therefore used in high-speed machines, instruments, and radioactive devices, but has a lower load capacity than oil. The air bearing can provide extremely high radial and axial rotation precision, and the abrasion degree is reduced to the minimum due to no mechanical contact, so that the precision is always kept stable.

The invention can be illustrated by the following operating modes:

continuously injecting water into the main body 1 through the water inlet pipe 11, wherein water flow enters the main body and is connected with a water conservancy pipeline through the water inlet pipe 11 and the water discharge pipe 12;

the water flow entering through the water inlet pipe 11 drives the impeller 5, so that the impeller 5 rotates by taking the primary bearing 7 as a fulcrum;

meanwhile, the impeller 5 drives the connecting pipe 10 to synchronously rotate by taking the secondary bearing 9 on the inner pipe 8 as a fulcrum through the filter cartridge 4;

in the process, the filter cartridge 4 rotates to filter the water source in the main body 1, the impurities with larger volume are blocked outside the filter cartridge 4, the clean water source enters the inner pipe 8 through the sieve holes, then flows into the base 1 through the inner pipe 8, and finally is discharged outwards through the drain pipe 12;

in the post-cleaning, the valve 14 is opened so that the dirt remaining in the main body 1 is discharged outside through the soil discharge pipe 13.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
