Description

Technical Field

[0001] The invention relates to the field of fluid medium filtration, and in particular to an anti-blocking rotary filter screen device. Background Art

[0002] Sedimentation and filtration are common causes of blockage in traditional cone filters and Y-type filters. For example, when a large power plant fuel oil system first circulates oil, due to poor pipeline cleanliness, a lot of debris and impurities are deposited in the filter, clogging the filter, resulting in insufficient oil pressure in front of the furnace. In order to clean the filter, the machine has to be shut down.

[0003] In addition, the boiler water circulation pump is a large flow, low head single-stage centrifugal pump installed in the boiler evaporation system to withstand high temperature and high pressure to force the working fluid to flow. Its structure includes three parts: pump housing and impeller, bearing, and insulation. Once the internal cooling water filter of large precision equipment such as the boiler water circulation pump is blocked, the cooling effect of the motor body will be reduced, which will cause the motor to trip and protect, seriously affecting normal production activities.

[0004] In summary, filter blockage is very harmful, and the above technical problems have not been effectively solved at this stage. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem of cooling water filter screen blockage in the prior art, the present invention provides an anti-blocking rotary filter screen device.

[0006] The technical solution of the present invention is:

[0007] A blocking-proof rotary filter device comprises a flow channel, a first rotary filter cartridge and a second rotary filter cartridge; the flow channel comprises at least a pair of plane tube walls; the first rotary filter cartridge and the second rotary filter cartridge are both arranged perpendicular to the plane tube walls of the flow channel;

[0008] The first rotary filter cartridge and the second rotary filter cartridge are respectively provided with two symmetrically distributed slits; the slits are parallel to the central axes of the first rotary filter cartridge and the second rotary filter cartridge; the first rotary filter cartridge and the second rotary filter cartridge are cross-arranged; the two slits on the first rotary filter cartridge are on the rotation track of the second rotary filter cartridge; the two slits on the second rotary filter cartridge are on the rotation track of the first rotary filter cartridge;

[0009] Particle collector 1, particle collector 2, and particle collector 3 are respectively arranged above the intersection part in rotary filter cartridge 1, the intersection part between rotary filter cartridge 1 and rotary filter cartridge 2, and below the intersection part in rotary filter cartridge 2; the central axes of particle collector 1, particle collector 2, and particle collector 3 are parallel to the central axes of rotary filter cartridge 1 and rotary filter cartridge 2.

[0012] Further preferably, the inner wall of the flow channel is provided with a supporting wheel 1 for supporting a rotating filter cartridge 1.

[0013] As a preferred solution, the inner wall of the end of the rotating filter drum 2 without the slit is provided with a power wheel 3 and a power wheel 4; the power wheel 3 is connected to the transmission belt 2 through the rotating shaft 3; the power wheel 4 is connected to the transmission belt 2 through the rotating shaft 4.

[0014] Further preferably, the inner wall of the flow channel is provided with a supporting wheel 2 for supporting the rotating filter cartridge 2.

[0018] Further preferably, the ratio of the diameter of the particle collector to the flow channel width is 1:4 to 1:5.

[0019] When the anti-clogging rotary filter device of the present invention is used, the fluid enters from the flow channel, and after debris accumulates on the outer side of the rotary filter cartridge one, the rotary filter cartridge one rotates an integer number of circles, and the rotary filter cartridge two does not move when the rotary filter cartridge one rotates; during the rotation process, the debris is flushed by the fluid and falls into the rotary filter cartridge two (below the intersection of the rotary filter cartridge one and the rotary filter cartridge two), and is collected by the particle collector three, with a small portion falling on the inner side of the rotary filter cartridge two.

In order to increase the stability of the rotating filter cartridge 1, a supporting wheel 11 for supporting the rotating filter cartridge 1 is provided on the inner wall of the flow channel 8. The supporting wheel 11 is fixed to the inner wall of the flow channel 8 through a connecting rod, and the supporting wheel 11 is located on the lower outer side of the rotating filter cartridge 1.

[0057] When the anti-clogging rotary filter device of the present invention is used, the fluid enters from the flow channel, and after the debris accumulates on the outside of the rotary filter cartridge 1, the rotary filter cartridge 1 rotates an integer number of circles, and the rotary filter cartridge 2 does not move when the rotary filter cartridge 1 rotates; during the rotation process, the debris is flushed by the fluid and falls into area A (below the intersection of the rotary filter cartridge 1 and the rotary filter cartridge 2 2), and is collected by the particle collector 3, and a small part falls into area A (inside the rotary filter cartridge 2 2).

[0058] Then, rotary filter cartridge 1 stops, and rotary filter cartridge 2 starts to rotate an integer number of circles (during the rotation of rotary filter cartridge 2, rotary filter cartridge 1 remains stationary). During the rotation of rotary filter cartridge 2, the debris in area A (inside of rotary filter cartridge 2) enters area B (the intersection of rotary filter cartridge 1 and rotary filter cartridge 2), is collected by particle collector 24, and a small part remains in area B.

[0059] The debris that falls into area B can enter area C (the space above the cross section in the rotary filter cartridge 1) during the next rotation of the rotary filter cartridge 1 and be collected by the particle collector 5.
