Since the concentrated or digested sludge is still in a liquid flow state and has a large volume, it needs to be further dehydrated to reduce its water content.

[0003] In the existing desludging machine technology for sewage treatment, when there is sludge in the sewage, the sewage is transported to the inside of the desludging machine through a pipe, the sludge in the sewage is separated and removed, and the sewage and sludge are transported by the rotation of the spiral blades. During the transportation process, the sewage will flow out of the filter net, and the sludge will be transported to the discharge port by the spiral blades.

[0004] Since the sewage and sludge are separated by spiral blades and filter screens, due to excessive water content in the sludge and the adhesion of the sludge and sewage together, a small amount of sewage may remain in the sludge during the rotation of the spiral blades, and the small amount of sewage cannot be separated from the sludge.

The extruded mud disc 113 is inserted into the extruded mud cylinder groove 107, and a first leakproof sheet 114 is welded at the lower end of the extruded mud cylinder groove 107. The first leakproof sheet 114 is connected and fixed to the second leakproof sheet 115 by bolts, and the lower end of the second leakproof sheet 115 is connected and fixed to the filter screen cylinder 116 by bolts. A spiral blade 119 is installed inside the filter screen cylinder 116, and the spiral blade 119 is connected and fixed to the rotating shaft 111 by welding. One end of the rotating shaft 111 is connected to the inside of the extruded mud disc 113 by penetrating, and one end of the rotating shaft 111 is connected and fixed to the servo motor 106 by bolts. The filter screen cylinder 11 6 is provided with a water filtering hole 117 at the lower end, and a mud discharge notch 112 is provided at the lower end of the mud extrusion cylinder groove 107. In actual use, when sewage is transported to the interior of the filter screen cylinder 116 through the pipeline, the servo motor 106 is driven to drive the rotating shaft 111 and the spiral blade 119 to rotate, and the sludge in the sewage is further transported to the interior of the mud extrusion cylinder groove 107 through the rotating shaft 111 and the spiral blade 119, and the sewage flows into the interior of the sewage tank cylinder 301 through the water filtering hole 117 of the filter screen cylinder 116, and the lifting guide column 108 is driven by the lifting hydraulic cylinder 105 to lift the sewage. The movement further drives the moving disc 109 and the connecting column 110 to move inside the extruded mud barrel groove 107, and the extruded mud disc 113 can be moved. The spiral blade 119 continuously transmits the sludge to it, and the sludge is moved and extruded in the extruded mud barrel groove 107, and finally a small amount of sewage in the sludge is extruded and separated. Because the extruded mud barrel groove 107 and the filter screen cylinder 116 are inclined, after the sludge in the extruded mud barrel groove 107 is squeezed, the extruded mud disc 113 is moved back and forth, and the thrust generated by the rotation of the spiral blade 119 is added to discharge the squeezed sludge from the mud discharge groove 112.

[0026] In actual use, by utilizing the lifting hydraulic cylinder 105 and the lifting guide column 108, the squeezing mud disc 113 and the squeezing mud tube groove 107, the connecting column 110 and the moving disc 109, the rotation of the spiral blade 119 can effectively transfer the sludge and extrude it in the squeezing mud tube groove 107. The squeezing action helps to separate as much water as possible from the sludge, achieve better dehydration effect, and finally squeeze and separate a small amount of sewage in the sludge.

[0027] Second embodiment:

[0028] like Figure 2-3 As shown, a cleaning disc 118 is sleeved on the outside of the water filtering hole 117 of the filter screen cylinder 116. The cleaning disc 118 is a structure made of several plastic brushes. The upper end of the cleaning disc 118 is connected and fixed to the moving block 203 by welding. The inside of the moving block 203 is penetrated and connected with a threaded screw 202. One end of the threaded screw 202 is connected and fixed to the rotating motor 205 by bolts. The rotating motor 205 is connected and fixed to the fixed block 201 by bolts. A bearing 204 is installed at one end of the threaded screw 202. When the water filtering hole 117 of the filter screen cylinder 116 is clogged with sludge, the threaded screw 202 is driven by the rotating motor 205 to rotate, thereby further driving the moving block 203 and the cleaning disc 118 to move. Through the movement of the cleaning disc 118, the water filtering hole 117 of the filter screen cylinder 116 can be scraped, thereby further dredging the water filtering hole 117 of the filter screen cylinder 116.

[0029] In this embodiment, by utilizing the cleaning disk 118 and the moving block 203, the threaded screw 202 and the rotating motor 205, the movement of the cleaning disk 118 can scrape the water filter hole 117 of the filter screen cylinder 116, scrape the blocked dirt from the hole, restore the normal unobstructed state of the hole, and ensure the normal operation of the water filter hole 117 of the filter screen cylinder 116. By regularly cleaning the water filter hole 117 of the filter screen cylinder 116, sludge blockage can be prevented from affecting the normal filtration of sewage water.

[0030] Third embodiment:

[0032] Fourth embodiment:

[0033] like Figure 1-3As shown, the two ends of the sewage trough 301 are connected and fixed with the first leak-proof sheet 114 and the second leak-proof sheet 115 by bolts. The first leak-proof sheet 114 and the second leak-proof sheet 115 are usually made of corrosion-resistant and wear-resistant metal materials. Common materials include stainless steel, copper alloy or other alloy materials. The lower end of the sewage trough 301 is connected with a sewage outlet 302, and the sewage is discharged from the sewage outlet 302.

The sewage inlet pipe 120 is installed at the lower end of the filter mesh cylinder 116. The first leak-proof sheet 114 and the second leak-proof sheet 115 can prevent the sewage trough 301 from leaking.

[0034] In this embodiment, by utilizing the first leak-proof sheet 114 and the second leak-proof sheet 115 and installing the leak-proof sheets at both ends of the sewage tank 301, it is possible to effectively prevent sewage from leaking out of the joints, thereby ensuring the complete collection and safe treatment of sewage and effectively preventing sewage from penetrating into external parts and causing damage.

A mud box 104 is placed on the upper end of the base 101, and the mud box 104 is aligned with the lower end of the mud discharge groove 112. When the squeezed sludge is discharged from the mud discharge groove 112, it directly falls into the mud box 104 for further centralized cleaning.

[0037] When in use, first, when sewage is transported to the interior of the filter screen cylinder 116 through the pipeline, the servo motor 106 is driven to drive the rotating shaft 111 and the spiral blade 119 to rotate, and the rotating shaft 111 and the spiral blade 119 are further rotated to transport the sludge in the sewage to the interior of the extrusion mud cylinder trough 107, and the sewage flows into the interior of the sewage tank cylinder 301 through the water filtering hole 117 of the filter screen cylinder 116, and the lifting guide column 108 is driven to move by driving the lifting hydraulic cylinder 105, and further drives the moving disk 109 and the connecting The column 110 moves inside the extrusion mud cylinder groove 107, and the extrusion mud plate 113 can be moved. The spiral blade 119 continuously transmits the sludge, and the sludge is moved and squeezed in the extrusion mud cylinder groove 107, and finally a small amount of sewage in the sludge is squeezed and separated. Because the extrusion mud cylinder groove 107 and the filter cylinder 116 are inclined, after the sludge in the extrusion mud cylinder groove 107 is squeezed, the extrusion mud plate 113 is moved back and forth, and the thrust generated by the rotation of the spiral blade 119 is added to discharge the squeezed sludge from the mud discharge groove 112.
