[0002] With the acceleration of industrialization and urbanization, a large amount of silt has accumulated at the bottom of water bodies such as rivers, lakes and reservoirs. These silts not only contain rich nutrients, but also may contain harmful substances such as heavy metals. The accumulation of silt not only affects the water storage capacity of the water body, but also causes water quality deterioration, affecting the ecological environment and human health. Therefore, in order to optimize the environment, silt needs to be treated.

[0003] At present, in the process of treating sludge, it is usually necessary to first use a filter press to dehydrate the sludge to squeeze out the water in the sludge to form dry mud that is convenient for subsequent use.

[0029] like Figure 2 and Figure 3 As shown, the filtering mechanism includes a side plate 41, a rotating drum 42, a filter plate 43, a large outer gear ring 44 and a driving assembly. The left and right sides of the treatment drum 2 are connected to the side plates 41, and openings for adding sludge are provided in the middle of the two side plates 41. The rotating drum 42 is rotatably connected between the two side plates 41. A plurality of filter plates 43 are evenly spaced and connected to the rotating drum 42. The filter plates 43 are used to filter water in the sludge. The left and right sides of the rotating drum 42 are connected to the large outer gear ring 44. The base 1 is provided with a driving assembly, and the driving assembly can drive the large outer gear ring 44 to rotate.

[0030] like Figure 3 As shown, the driving assembly includes a driving motor 51 and a driving gear 52. The driving motor 51 is installed on the left side of the base 1. The driving gear 52 is connected to the output shaft of the driving motor 51. The driving gear 52 is engaged with the large outer gear ring 44 so that the operation of the driving motor 51 can drive the large outer gear ring 44 to rotate through the driving gear 52.

[0031] like Figure 4 As shown, it also includes an extrusion mechanism, which includes a guide plate 61 and a pressure roller 62. An inclined guide plate 61 is arranged between the lower left parts of the two side plates 41, and the guide plate 61 can extrude the sludge. The top of the guide plate 61 is rotatably connected to a pressure roller 62, and the pressure roller 62 can extrude the sludge, thereby performing filter press treatment on the sludge.

[0032] like Figure 3 and Figure 5 As shown, the unloading mechanism includes a guide frame 71, a discharge pipe 72, an inner gear ring 73, a transmission gear 74, a spiral feed shaft 75 and a scraper 76. The guide frame 71 is connected between the upper parts of the two side plates 41. The right side of the bottom of the guide frame 71 is connected to the discharge pipe 72. The left side of the rotating drum 42 is connected to the inner gear ring 73. The guide frame 71 is rotatably connected to the spiral feed shaft 75. The rotation of the spiral feed shaft 75 can transport the sludge, so that the sludge is discharged through the discharge. The spiral feed shaft 75 is sent out through the tube 72, and a transmission gear 74 is connected to the left side of the spiral feed shaft 75, and the transmission gear 74 is meshed with the inner ring gear 73, so that when the drum 42 rotates, the spiral feed shaft 75 can be driven to rotate through the inner ring gear 73 and the transmission gear 74, and a scraper 76 is connected to the upper inner part of the guide frame 71, and the scraper 76 is in contact with the inner wall of the filter plate 43, so that when the drum 42 and the filter plate 43 rotate, the scraper 76 can scrape off the sludge on the inner wall of the filter plate 43.

[0033] When the sludge needs to be treated, the device can be used to treat the sludge. During the treatment, the sludge is first loaded into the drum 42 through the opening in the middle of the side plates 41 on both sides. The filter plate 43 can filter the water in the sludge, and the filtered water will enter the lower part of the treatment drum 2. Then the valve can be opened so that the water will be discharged through the drain pipe 3. After the sludge is added to the drum 42, the drive motor 51 can be controlled to drive the drive gear 52 to rotate. The drive gear 52 can drive the large outer gear ring 44 to rotate when rotating. The large outer gear ring 44 can drive the drum 42 and the filter plate 43 to rotate when rotating. The drum 42 can drive the sludge inside it to move when rotating. The sludge will contact the guide plate 61 and the pressure roller 62 when moving. The guide plate 61 and the pressure roller 62 can squeeze the sludge, thereby The filter press treatment is carried out so that the water mixed in the sludge will pass through the filter plate 43, and the residual sludge will adhere to the inner wall of the drum 42 and the filter plate 43. Then, the drum 42 and the filter plate 43 rotate, which can drive the sludge to contact with the scraper 76, and the sludge is scraped to the guide frame 71 by the scraper 76, and the sludge is collected by the guide frame 71. When the drum 42 rotates, it can drive the inner gear ring 73 to rotate, and the inner gear ring 73 can drive the transmission gear 74 to rotate when it rotates. When the transmission gear 74 rotates, it can drive the spiral feed shaft 75 to rotate. The rotation of the spiral feed shaft 75 can transport the sludge in the guide frame 71 backward, so that the sludge is discharged through the discharge pipe 72. This is repeated, and the sludge can be continuously added and processed. After the processing is completed, there is no need to manually unload the residual sludge, which is more convenient to operate.

[0034] like Figure 6 and Figure 7 As shown, it also includes a coarse filter mechanism, which includes a coarse filter cartridge 81, a small outer gear ring 82 and a pinion 83. The coarse filter cartridge 81 is rotatably connected between the middle parts of the two side plates 41, and the small outer gear ring 82 is connected to the left side of the coarse filter cartridge 81. The pinion gear 83 is rotatably connected to the left side plate 41. The two sides of the pinion gear 83 are respectively meshed with the small outer gear ring 82 and the transmission gear 74, so that the transmission gear 74 can drive the small outer gear ring 82 to rotate through the pinion gear 83 when it rotates.

[0035] When adding sludge, the sludge can be added to the coarse filter cartridge 81 first, and impurities such as gravel mixed in the sludge will be blocked by the coarse filter cartridge 81, while the sludge and water can pass through the coarse filter cartridge 81 and enter the rotating drum 42, thereby achieving the effect of preliminary filtration of the sludge. When the transmission gear 74 rotates, the small outer gear ring 82 can be driven to rotate through the small gear 83, thereby driving the coarse filter cartridge 81 to rotate, and assisting in throwing out the sludge and water inside the coarse filter cartridge 81 to avoid sludge and water being blocked inside the coarse filter cartridge 81.

[0036] like Figure 8As shown, a pumping mechanism is also included, and the pumping mechanism includes an air suction pipe 91, an exhaust pipe 92, a solenoid valve 94 and a baffle plate 93. A plurality of exhaust pipes 92 are evenly spaced and connected to the front side of the treatment tube 2, and an air suction pipe 91 is connected between the front sides of the plurality of exhaust pipes 92. Two baffle plates 93 are provided on the front side wall of the treatment tube 2, and the area between the two baffle plates 93 constitutes a pumping cavity. The rear end of the exhaust pipe 92 is located in the pumping cavity, and a solenoid valve 94 is installed on the lower baffle plate 93.

[0037] When using this treatment machine, the suction end of the vacuum pump can be connected to the vacuum pipe 92, and then the vacuum pump can be controlled to operate, so that the vacuum pipe 92 can be evacuated to generate negative pressure in the water pumping cavity, thereby assisting in extracting the water remaining on the sludge attached to the inner wall of the filter plate 43. The extracted water will be located in the water pumping cavity. When a certain amount of water accumulates in the water pumping cavity, the vacuum pump can be turned off, and then the solenoid valve 94 at the lower baffle plate 93 can be opened to discharge the water. In this way, the residual water in the sludge can be extracted.

[0038] like Figure 4 As shown, a flushing mechanism is also included, and the flushing mechanism includes a water pump 101, a water suction pipe 102, a guide pipe 103, a water outlet pipe 105 and a nozzle 104.

The water outlet pipe 105 is connected between the guide pipe 103 and the water outlet end of the water pump 101.

[0039] When water enters the bottom of the treatment tube 2, the valve can be controlled to close, and then the water pump 101 can be controlled to operate to pump water through the suction pipe 102 and inject water into the nozzle through the outlet pipe 105 and the guide pipe 103. The water is sprayed on the filter plate 43 through the nozzle to flush away the sludge stuck in the holes of the filter plate 43, thereby preventing the sludge from being stuck in the holes of the filter plate 43.

[0040] like Fig. 9 As shown, a dilution mechanism is also included, and the dilution mechanism includes a second nozzle 112, a water pipe 111, a second water pump 113, a water suction pipe 114 and a connecting pipe 115. Two water pipes 111 are connected between the lower parts of the two side plates 41, and multiple second nozzles 112 are evenly spaced on the two water pipes 111. The second nozzle 112 faces the coarse filter cartridge 81. A second water pump 113 is installed on the left side of the base 1. A water suction pipe 114 is connected between the liquid inlet end of the second water pump 113 and the treatment cartridge 2. A connecting pipe 115 is connected to the liquid outlet end of the second water pump 113, and the connecting pipe 115 is connected to the two water pipes 111.

[0041] After the control valve is closed, the water pump 113 can also be controlled to operate to pump water out through the pumping pipe 114 and inject it into the connecting pipe 115, and then inject the water into the water pipe 111 through the connecting pipe 115, and finally the water is sprayed out through the nozzle 112, so that the water is sprayed into the coarse filter cartridge 81, diluting the sludge in the coarse filter cartridge 81 so that the sludge can pass through the coarse filter cartridge 81 better.

[0042] This embodiment also provides a sludge treatment method, the specific steps are as follows: S1: The sludge is loaded into the rotating drum 42 through the opening in the middle of the side plates 41 on both sides. The filter plate 43 filters the water in the sludge. The filtered water enters the lower part of the treatment drum 2. The valve is opened and the water is discharged through the drain pipe 3. S2: Control the driving motor 51 to drive the driving gear 52 to rotate. The driving gear 52 rotates to drive the large outer gear ring 44 to rotate. The large outer gear ring 44 rotates to drive the drum 42 and the filter plate 43 to rotate. The drum 42 rotates to drive the sludge inside to move. The sludge moves and contacts with the guide plate 61 and the pressure roller 62. The guide plate 61 and the pressure roller 62 squeeze the sludge and perform filter press treatment on the sludge. S3: The residual sludge adheres to the inner wall of the drum 42 and the filter plate 43. The drum 42 and the filter plate 43 continue to rotate to drive the sludge to contact the scraper 76. The scraper 76 scrapes the sludge to the guide frame 71, and the guide frame 71 collects the sludge. S4: When the drum 42 rotates, it can drive the inner gear ring 73 to rotate, and the rotation of the inner gear ring 73 drives the transmission gear 74 to rotate, and the rotation of the transmission gear 74 drives the spiral feeding shaft 75 to rotate.
