[0034] As Figures 1-4 ​​As shown, the present application provides a sludge conveying pipeline, which comprises a base 1 and a sludge conveying pipe 2 fixedly arranged on the base 1, the sludge conveying pipe 2 being a main channel for sludge conveying, and the sludge conveying pipe 2 having an input port and an output port so as to realize the purpose of conveying sludge;

[0035] Meanwhile, in order to prevent the blockage of the sludge conveying pipe 2 by large impurities and particles during the conveying of sludge, a filtering mechanism 5 is fixedly arranged inside the sludge conveying pipe 2, which is used to prevent large sludge or impurities from entering the pipeline, thereby preventing the blockage from occurring;

[0036] The filtering mechanism 5 comprises a cover 3 fixedly arranged outside the sludge conveying pipe 2, which is used to prevent external impurities from entering the filtering mechanism 5, thereby affecting its work, and a valve seat 51 is fixedly arranged on one side of the cover 3, and a pin shaft 52 is rotatably arranged between the valve seats 51, and one end of the pin shaft 52 extends to the inside of the sludge conveying pipe 2 through the cover 3;

[0037] A filler 55 is fixedly arranged at the connection between the valve seat 51 and the pin shaft 52, which is used to fill the pin shaft 52 to prevent sludge from leaking through the gap between the pin shaft 52 and the valve seat 51;

[0038] A hand wheel 50 is fixedly arranged at one end of the pin shaft 52 close to the valve seat 51, which is used to provide an interface for manual operation of the staff, and the pin shaft 52 can be driven to rotate by rotating the hand wheel 50;

[0039] Meanwhile, a fixing ring 53 is fixedly arranged inside the sludge conveying pipe 2, and a filter screen 54 is rotatably arranged inside the fixing ring 53, which is used to trap impurities and particles in the sludge to ensure that small-particle sludge passes through the filter screen 54, thereby preventing large-particle sludge from blocking the sludge conveying pipe 2, and one end of the pin shaft 52 extending to the inside of the sludge conveying pipe 2 penetrates the fixing ring 53 and is fixedly connected with one end of the filter screen 54, so that the user can drive the filter screen 54 to rotate inside the fixing ring 53 by rotating the hand wheel 50 to drive the pin shaft 52;

[0040] In order to prevent the large-particle sludge trapped and further break the sludge after filtering, a stirring and crushing mechanism 6 is arranged at both ends of the filtering mechanism 5 inside the sludge conveying pipe 2, which is used to crush and refine large substances, entanglements or solid particles in the sludge;

[0041] The stirring mechanism 6 includes a motor 60 fixedly arranged at the upper end of the cover 3, the output end of the motor 60 extends to the inside of the sludge conveying pipe 2 through the cover 3, and a rotating shaft 61 is fixedly arranged on the output end of the motor 60 and located in the inside of the sludge conveying pipe 2, a plurality of broken blades 62 are fixedly arranged on the rotating shaft 61, and the broken blades 62 are arranged in a spiral on the rotating shaft 61, so as to break the large pieces or entanglements in the sludge, thereby ensuring the smooth conveying of the sludge.

[0042] When the sludge is filtered, the sludge first passes through the sludge conveying pipe 2 to the filtering mechanism 5, and after the filtering treatment of the sludge by the filter screen 54, the large pieces of sludge are intercepted outside the filter screen 54, and the sludge meeting the size passes through the filter screen 54.

[0043] At this time, when the motor 60 starts, it will power the rotating shaft 61, which will start to rotate under the drive of the motor 60 and drive the broken blades 62 to rotate, the broken blades 62 will break and refine the large pieces or entanglements in the sludge, so that they can enter the filter screen 54 for transportation, and the sludge passing through the filter screen 54 will be further refined, thereby achieving the purpose of preventing the sludge conveying pipe 2 from being blocked.

[0044] As shown in Figure 2 and Figure 5 , in order to prevent residues from adhering to the filter screen 54 during the filtering process, and to prevent the filter screen 54 from being blocked due to the accumulation of residues, thereby affecting the filtering effect, a plurality of water inlet pipes 7 are fixedly arranged at the upper end of the cover 3, the water inlet pipes 7 extend to the inside of the sludge conveying pipe 2 through the cover 3, and the water inlet pipes 7 are located directly above the filter screen 54, so as to clean the filter screen 54 through the water inlet pipes 7.

[0046] In order to prevent the cleaning of the filter screen 54 from polluting the sludge conveying pipe 2, a blocking mechanism 4 (refer to Figure 5 ) is fixedly arranged at both ends of the sludge conveying pipe 2, the blocking mechanism 4 includes two sets of fixed seats 40 fixedly arranged at both ends of the sludge conveying pipe 2.

[0047] Meanwhile, a mounting ring (not shown in the figure) is fixedly arranged in the fixed seat 40, and a sealing ring 44 is fixedly arranged at the connection between the mounting ring and the fixed seat 40, so as to ensure that the blocking mechanism 4 can be tightly sealed when closed, preventing leakage.

[0048] Meanwhile, a valve plate 43 for controlling the on-off of the sludge is arranged inside the installation ring and rotates, and a valve shaft 42 is fixedly arranged at the upper end of the valve plate 43, one end of the valve shaft 42 penetrating through the fixed seat 40 and extending to the outside;

[0049] Meanwhile, a handle 41 is fixedly arranged at one end of the valve shaft 42 extending to the outside, so that the operator can drive the valve shaft 42 by rotating the handle 41, and then drive the valve plate 43 to control the on-off of the sludge;

[0050] When the inside of the filter screen 54 needs to be cleaned, the handle 41 can be rotated to block the sludge from entering the inside and also to prevent the impurities cleaned from the filter screen 54 from entering the sludge conveying pipe 2, after the sludge is successfully blocked, the operator can rotate the plug 8 on the water inlet pipe 7, after the plug 8 is removed, the inside filter screen 54 can be flushed through the water inlet pipe 7, after the flushing is completed, the plug 8 on the water outlet pipe 9 can be removed, and the residues flushed out can be discharged.
