Example Embodiment

[0046] Example 1:
[0047] Such as figure 1 , figure 2 , Picture 10 As shown, a fluid filtration device is used in the filtration of sewage 7 with a high flow rate. It includes a rotating shaft 12, a cylindrical component 1 (such as a squirrel cage) fixed on the rotating shaft 12, and driving the cylindrical component 1 to rotate. The power source, the first tube 3 and the bracket 2.
[0048] The cylindrical member 1 is cylindrical, and a filter screen 11 is provided on the outer surface; both ends of the cylindrical member 1 are mounted on the rotating shaft 12, and one end of the rotating shaft 12 is hollow and mounted on the bracket 2, the rotating shaft 12 and the cylindrical member 1 rotate together on the bracket 2, and the bracket 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 drawing out the filtered water sample; the other end passes through the inside of the rotating shaft 12. The power source is flowing sewage 7.
[0049] According to the fluid filtration method of the embodiment of the present invention, that is, the working process of the above-mentioned filtration device, the fluid filtration method includes the following steps:
[0050] (A1) The flowing sewage 7 drives the cylindrical part 1, causing the cylindrical part 1 to rotate on the support, and a part of the cylindrical part 1 below the rotating shaft 12 is placed under the water surface of the sewage 7;
[0051] (A2) The sewage 7 enters the cylindrical part 1 after passing through the filter screen 11. The sludge and other solids in the sewage 7 will adhere to the outside of the filter 11, but the sludge and other solids are not enough on the one hand The centripetal force of the rotating cylindrical member 11 makes a circular motion, so it does centrifugal movement and is thrown out of the filter screen 11. On the other hand, the filter screen 11 rubs against the sewage 7 after entering the water surface of the sewage 7 to promote the attachment to the filter The sludge and other solids on the net 11 are separated from the filter 11; furthermore, due to the action of gravity, the dirt attached to the filter 11 will also fall into the sewage 7; thus ensuring that only the sewage 7 can enter Inside the rotating cylindrical part 1;
[0052] The sewage in the cylindrical part 1 is taken away by the first pipe 3 for use, such as detection; while solids such as sludge are isolated outside the filter 11.
[0053] It can be seen that in the above-mentioned filtering method, the filtering and cleaning are performed synchronously and continuous filtering; and the cleaning effect is good without clogging; the filtering device for realizing the above-mentioned filtering method has a simple structure and is easy to maintain; at the same time, the cost of the filtering device is reduced.

Example Embodiment

[0054] Example 2:
[0055] Such as image 3 , Figure 4 , Picture 11 As shown, a fluid filtration device is used in the filtration of sewage 7 with a higher flow rate. The difference from the filtration device in Example 1 is:
[0056] The filtering device also includes a second tube 4, one end of the second tube 4 extends into the cylindrical member 1, and a plurality of outflow ports 41 are provided on the second tube 4, and the direction of the outflow ports 41 is along the The cylindrical component 1 is not in a 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] According to the fluid filtration method of the embodiment of the present invention, that is, the working process of the above-mentioned filtration device, the fluid filtration method includes the following steps:
[0058] (A1) The flowing sewage 7 drives the cylindrical part 1, causing the cylindrical part 1 to rotate on the support, and a part of the cylindrical part 1 below the rotating shaft 12 is placed under the water surface of the sewage 7;
[0059] (A2) The sewage 7 enters the cylindrical part 1 after passing through the filter screen 11. The sludge and other solids in the sewage 7 will adhere to the outside of the filter 11, but the sludge and other solids are not enough on the one hand The centripetal force of the rotating cylindrical member 11 makes a circular motion, so it does centrifugal movement and is thrown out of the filter screen 11; on the other hand, the filter screen 11 rubs against the sewage 11 after entering the water surface, prompting it to be attached to the filter screen 11. The sludge and other solids on the filter screen 11; furthermore, due to the action of gravity, the dirt attached to the filter screen 11 will also fall into the sewage 7;
[0060] The sewage in the cylindrical part 1 is taken away by the first pipe 3 for use, such as detection; while solid objects such as sludge are isolated outside the filter 11;
[0061] (A3) The second pipe 4 uses gas to flush solids such as sludge on the rotating filter screen 11 from inside to outside, and the design of the direction of the outlet 41 can better drive the rotation of the cylindrical member 1 , Increase the rotational speed of the cylindrical part 1 to better remove the sludge and other solids on the filter screen 11; thereby ensuring that only sewage 7 can enter the rotating cylindrical part 1.
[0062] It can be seen that in the above-mentioned filtering method, the filtering and cleaning are performed synchronously and continuous filtering; and the cleaning effect is good without clogging; the filtering device for realizing the above-mentioned filtering method has a simple structure and is easy to maintain; at the same time, the cost of the filtering device is reduced.

[0063] Example 3:
[0064] Such as Figure 5 , Image 6 with Picture 10 As shown, a fluid filter device is used in the filtration of sewage 7 with a high flow rate. The difference from the filter device in Example 1 is:
[0065] The filtering device also includes a floating object 5 on the water surface of the sewage 7 and a fixing member. The bracket 2 is mounted on the floating object 5, such as a pontoon, so that the cylindrical member 1 floats on the water surface and follows The sewage 7 rises and falls on the water surface; the fixing member 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] According to the fluid filtration method of the embodiment of the present invention, that is, the working process of the above-mentioned filtration device, the fluid filtration method includes the following steps:
[0067] (A1) The flowing sewage 7 drives the cylindrical part 1, causing the cylindrical part 1 to rotate on the support, and a part of the cylindrical part 1 below the rotating shaft 12 is placed under the water surface of the sewage 7;
[0068] (A2) The sewage 7 enters the cylindrical part 1 after passing through the filter screen 11. The sludge and other solids in the sewage 7 will adhere to the outside of the filter 11, but the sludge and other solids are not enough on the one hand The centripetal force of the rotating cylindrical member 11 makes a circular motion, so it does centrifugal movement and is thrown out of the filter screen 11; on the other hand, the filter screen 11 rubs against the sewage 11 after entering the water surface to promote attachment to the cylindrical member The sludge and other solids on 1 leave the filter 11; furthermore, due to gravity, the dirt attached to the filter 11 will also fall into the sewage 7; thereby ensuring that only the sewage 7 can enter the rotation In the cylindrical part 1;
[0069] The sewage in the cylindrical part 1 is taken away by the first pipe 3 for use, such as detection; while solid objects such as sludge are isolated outside the filter 11;
[0070] When the water surface of the sewage 7 fluctuates, the floating object 5 will rise and fall with the fluctuation of the water surface, and then drive the cylindrical member 1 up and down through the rotating shaft 12, so as to make the bottom of the rotating shaft 12 A part of the cylindrical member 1 is always under the surface of the sewage 7.
[0071] It can be seen that in the above-mentioned filtering method, the filtering and cleaning are performed synchronously and continuous filtering; and the cleaning effect is good without clogging; the filtering device for realizing the above-mentioned filtering method has a simple structure and is easy to maintain; at the same time, the cost of the filtering device is reduced.
