Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a desludging machine for sewage treatment. Background Art

[0002] Sewage treatment is an important part of environmental protection. The desludging process in sewage treatment is to simply filter and separate the large amount of sludge in the sewage in order to remove the mud blocks in the sewage and facilitate the subsequent treatment of the sewage.

[0003] The utility model patent with patent authorization announcement number CN 219792531 U discloses a desludging machine for sewage treatment, including a treatment box: a filter plate is fixedly connected between the left and right inner walls of the treatment box, a feed frame is fixedly connected to the left side of the treatment box, a hydraulic rod is fixedly connected to the inner wall on the upper side of the treatment box, and a lower pressure plate is fixedly connected to the lower end of the hydraulic rod, a cleaning unit is provided on the right side of the treatment box, a discharge hole is opened on the right side of the treatment box, and the cleaning unit includes two fixed blocks, the two fixed blocks are fixedly connected to the right side of the treatment box, and a slide groove is opened on the outer side of the two fixed blocks, and a slider is slidably connected to the inner side of the slide groove.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when the lower pressure plate compresses the sludge, some of the sludge will enter the filter holes on the surface of the filter plate. When the subsequent push plate pushes the sludge, this part of the sludge cannot be pushed out, but remains inside the filter holes. Therefore, with the extension of the use time, the number of filter holes blocked will continue to increase, thereby affecting the normal filtration of sewage, and the actual use effect is not ideal.

[0005] Therefore, it is necessary to invent a sewage treatment desludging machine to solve the above problems. Utility Model Content

At this time, the air pump inputs airflow into the cleaning shell through the transmission pipe, and the airflow is sprayed to the annular filter screen through multiple air holes, thereby removing the residual sludge in the filter holes, so as to solve the problem proposed in the above-mentioned background technology that when the lower pressure plate compresses the sludge, part of the sludge enters the filter holes on the surface of the filter plate, and when the subsequent push plate pushes the sludge, this part of the sludge cannot be pushed out, but remains in the filter holes. Therefore, with the extension of the use time, the number of blockages in the filter holes will continue to increase, thereby affecting the normal filtration of sewage and the problem that the actual use effect is not ideal.

[0033] Figure 2 It is a schematic structural diagram of a box mechanism 1, a driving water inlet mechanism 2 and a cleaning structure 4 of a desludging machine for sewage treatment according to an embodiment of the present disclosure.

[0034] Figure 3 It is a schematic structural diagram of a filtering mechanism 3 of a desludging machine for sewage treatment according to an embodiment of the present disclosure.

[0035] like Figure 1-Figure 3 As shown, the desludging machine for sewage treatment disclosed in the present invention may include: a box mechanism 1, a driving water inlet mechanism 2, a filtering mechanism 3, a cleaning structure 4 and a compression mechanism 5 and other components.

[0036] like Figure 2 As shown, in the present disclosure, the box mechanism 1 includes a processing box 11, a drain pipe 12 and a cleaning door 13, wherein the drain pipe 12 is fixedly arranged through the bottom of the front side of the processing box 11, and the cleaning door 13 is movably connected to the middle of the back side of the processing box 11 through a hinge.

[0037] Thus, the sewage falling into the bottom of the inner cavity of the treatment box 11 is discharged through the drain pipe 12. After the mud removal is completed, the cleaning door 13 is opened, and then the sludge inside the annular filter 31 is cleaned through the cleaning window on the rear side of the treatment box 11.

[0038] like Figure 2As shown, in a preferred embodiment, the driving water inlet mechanism 2 includes a water inlet pipe 21, a driving motor 22 and a driving gear 23, wherein the water inlet pipe 21 is arranged through the front of the treatment box 11 and is rotatably connected to the treatment box 11 through a bearing, the driving motor 22 is fixedly arranged on the top of the front of the treatment box 11, and two driving gears 23 are provided, the two driving gears 23 are meshed with each other, one driving gear 23 is transmission-connected to the driving motor 22, and the other driving gear 23 is fixedly sleeved on the outside of the water inlet pipe 21.

[0039] Thus, the sewage pipe is connected to the water inlet pipe 21 through a rotating joint, and the sewage enters the annular filter screen 31 through the water inlet pipe 21 to be filtered. At the same time, the driving motor 22 drives the water inlet pipe 21 to rotate through the driving gear 23, and then the water inlet pipe 21 drives the end plate 32 to rotate.

[0040] like Figure 3 As shown, in the present disclosure, the filtering mechanism 3 includes an annular filter 31 and an end plate 32, wherein the drain pipe 12 is fixedly penetrated through the bottom of the front side of the treatment box 11, the cleaning door 13 is movably connected to the middle of the back side of the treatment box 11 through a hinge, and the end plate 32 is fixedly arranged on the inner side of the annular filter 31, and the end plate 32 is fixedly sleeved on the outer side of the water inlet pipe 21.

[0041] Therefore, when the end plate 32 rotates, the annular filter screen 31 is driven to rotate, and when the annular filter screen 31 rotates, the residual sludge is driven to approach the cleaning structure 4, so that the cleaning structure 4 can clean the residual sludge.

[0042] like Figure 2 As shown, in the present disclosure, the cleaning structure 4 includes an air pump 41, a transmission pipe 42 and a cleaning shell 43, wherein the air pump 41 is fixedly arranged on the top of the processing box 11, the transmission pipe 42 is fixedly penetrated through the top of the processing box 11, the top end of the transmission pipe 42 is fixedly connected to the output end of the air pump 41, the bottom end of the transmission pipe 42 is fixedly penetrated through the top of the cleaning shell 43, the cleaning shell 43 is fixedly arranged on the top of the inner cavity of the processing box 11, and a plurality of air holes are penetrated through the bottom of the cleaning shell 43.

[0043] Thus, the air pump 41 inputs airflow into the cleaning shell 43 through the transmission pipe 42, and the airflow is sprayed toward the position adjacent to the annular filter 31 and the cleaning shell 43 through multiple air holes, thereby removing the sludge remaining in the filter holes.

[0044] like Figure 2As shown, in a preferred embodiment, the compression mechanism 5 includes a mounting plate 51, a hydraulic cylinder 52 and a pressure block 53, wherein the mounting plate 51 is fixedly connected to the inner wall of the processing box 11, the hydraulic cylinder 52 is fixedly arranged on the top of the mounting plate 51 and its output shaft passes through the mounting plate 51 and extends to the bottom of the mounting plate 51 and is fixedly connected to the pressure block 53.

[0045] Therefore, the hydraulic cylinder 52 drives the pressing block 53 to move downward, so that the pressing block 53 squeezes the sludge, and the sewage remaining in the sludge passes through the annular filter screen 31 and enters the bottom of the inner cavity of the processing box 11.
