Embodiment 1

[0047] Such as figure 1 , figure 2 , Figure 10 As shown, a fluid filter device is used in the filtration of sewage 7 with a high flow rate, comprising a rotating shaft 12, a cylindrical part 1 (such as a squirrel cage) fixed on the rotating shaft 12, and driving the cylindrical part 1 to rotate The power source, the first tube 3 and the bracket 2.

[0048] The cylindrical part 1 is cylindrical, and a filter screen 11 is arranged on the outer surface; the two ends of the cylindrical part 1 are installed on the rotating shaft 12, and one end of the rotating shaft 12 is hollow and installed on the bracket 2, the rotating shaft 12 and the cylindrical part 1 rotate together on the support 2, and the support 2 is installed in the sewage tank. A part of the cylindrical part 1 below the rotating shaft 12 is placed under the water surface of the sewage 7 . One end of the first tube 3 extends into the cylindrical part 1 for extracting filtered water samples; the other end passes t...

Embodiment 2

[0055] Such as image 3 , Figure 4 , Figure 11 As shown, a fluid filter device is used in the filtration of sewage 7 with a higher flow rate. The difference from the filter device in Example 1 is:

[0056] The filtering device also includes a second pipe 4, one end of the second pipe 4 extends into the cylindrical part 1, and several outlets 41 are arranged on it, and the direction of the outlets 41 is along the The cylindrical part 1 is in a non-radial tangential direction; the other end of the second tube 4 passes through the inside of the rotating shaft 12 and is fixed on the bracket 2 .

[0057] The fluid filtering method of the embodiment of the present invention, that is, the working process of the above-mentioned filtering device, the fluid filtering method includes the following steps:

[0058] (A1) The flowing sewage 7 drives the cylindrical part 1, so that the cylindrical part 1 rotates on the support, and a part of the cylindrical part 1 below the rotating shaf...

Embodiment 3

[0064] Such as Figure 5 , Figure 6 and Figure 10 As shown, a fluid filter device is used in the filtration of sewage 7 with a high flow rate, and the difference from the filter device in Example 1 is:

[0065] The filtering device also includes floating objects 5 and fixtures on the water surface of the sewage 7, and the support 2 is installed on the floating objects 5, such as buoys, so that the cylindrical part 1 floats on the water surface, and along with The water surface of the sewage 7 is raised and lowered; the fixed part is a rope, which is used to prevent the flowing sewage 7 from washing away the cylindrical part 1 floating on the water surface.

[0066] The fluid filtering method of the embodiment of the present invention, that is, the working process of the above-mentioned filtering device, the fluid filtering method includes the following steps:

[0067] (A1) The flowing sewage 7 drives the cylindrical part 1, so that the cylindrical part 1 rotates on the su...

Abstract

The invention discloses a fluid filtering method and a fluid filtering device. The fluid filtering device comprises a filtering medium, and further comprises a bracket, a cylindrical part, a first pipe and a power source, wherein a rotating shaft is arranged on the bracket; the cylindrical part is hollow, and two ends of the cylindrical part are arranged on the rotating shaft; the filtering medium is arranged on an outer edge of the cylindrical part; the first pipe penetrates through the interior of the rotating shaft, and an inlet end of the first pipe is positioned in the cylindrical part; and the power source is used for driving the cylindrical part to rotate. According to the filtering method and the filtering device, the operations of filtering and cleaning are synchronously performed, the cleaning effect is good, and blockage is avoided. Moreover, the filtering device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to fluid filtration, in particular to a fluid filtration method and device. Background technique [0002] Fluid filtering device is a widely used device for purifying fluid, which is used to filter out impurities in fluid, such as solids such as sludge. At present, the vast majority of filter devices use direct filtration: let all the fluid pass through the filter with a certain pore size in the filter, and the cleaner fluid after passing through the filter is used for analysis or use, while the impurities are trapped in the filter. On one side of the filter screen, solids such as a small amount of sludge entering through the filter screen will also be deposited at the bottom of the filter. Therefore, this filter device is easy to block, and the filter needs to be disassembled frequently to clean the filter screen. The maintenance workload is large, and the service efficiency of the filter device is not high. [0003] In order t...
