For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments:

[0027] Example 1

[0028] like Figure 1-6As shown, the utility model provides a sludge treatment device with a filter pressing function, including a mounting frame 1, a pressure assembly 2, a support rod 5 and a rotating receiving frame 3. The outer wall of the rotating receiving frame 3 is provided with receiving frames 13 in a circular array. The inner walls of multiple groups of receiving frames 13 are fixedly connected to limit bars 19. The inner wall of the receiving frame 13 located at the bottom of the limit bars 19 is plugged with a receiving filter plate 14. When the electric push rod 9 pushes the pressing plate 8 to move down to the inside of the receiving frame 13, the downwardly moved cover 10 docks with the outer edge of the receiving frame 13, and the receiving frame 13 is sealed by the elastic force of the limit spring 12.

[0029] The pressure-applying assembly 2 is located at the top of the inner wall of the mounting frame 1 , and includes a pressure plate 8 that fits the inner wall of the receiving frame 13 , a downwardly movable cover 10 that is sealed at the top of the rotating receiving frame 3 , and a liquid injection tube 11 that passes through the bottom surface of the pressure plate 8 .

[0030] A central collecting pipe 21 is fixedly connected at the center of the inner wall of the rotating receiving frame 3, a collecting groove 17 is opened on the outer wall of the central collecting pipe 21, guide inclined plates 15 are fixedly connected on both sides of the central collecting pipe 21, sealing collars 20 are fixedly connected at both ends of the central collecting pipe 21, a drain pipe 16 is rotatably connected to one side of the sealing collar 20, and the inner wall of the central collecting pipe 21 is fixedly connected to the outer wall of the support rod 5 through a fixing ring.

[0031] Example 2

[0032] like Figure 1-6 As shown, based on Example 1, the utility model provides a technical solution: preferably, the guide inclined plate 15 is used to separate the interior of the rotating receiving frame 3 into two parts, the upper and lower parts, and the side of the guide inclined plate 15 away from the drain pipe 16 is fixedly connected to the inner wall of the rotating receiving frame 3.

[0033] The inner wall of the drain pipe 16 is rotatably connected to one end of the support rod 5 , the outer wall of the sealing collar 20 is rotatably connected to the rotating support frame 3 through a bracket, and one end of the support rod 5 away from the drain pipe 16 is fixedly connected to a pulley.

[0034] The outer wall of the pulley is movably connected to the driving motor 7 through the belt, and the upper surface of the pressing plate 8 is fixedly connected to the extended end of the electric push rod 9 that movably penetrates the bottom of the downward cover 10, and the outer wall of the bottom end of the electric push rod 9 located above the downward cover 10 is sleeved with a limit spring 12. The inner edge of the bottom of the downward cover 10 is butted and sealed with the outer wall of the receiving frame 13.

[0035] The working principle of the sludge treatment device with filter pressing function is described in detail below.

[0036] like Figure 1-6As shown, when in use, when the sludge is subjected to filter pressure treatment, the electric push rod 9 is started, so that the electric push rod 9 pushes the pressure plate 8 and the downward cover 10 downward until the pressure plate 8 is placed on the top inner edge of the receiving frame 13. The downward cover 10 now covers the top outer edge of the receiving frame 13 to seal the receiving frame 13, and then the sludge is injected into the receiving frame 13 through the injection pipe 11. When the injection is completed, the electric push rod 9 pushes the pressure plate 8 to continue to move downward to compress the sludge. At this time, the sewage in the sludge is filtered into the interior of the rotating receiving frame 3 through the receiving filter plate 14, and the sewage entering the rotating receiving frame 3 enters the central collecting pipe 21 through the collecting trough 17 under the guidance of the guide inclined plate 15, and enters the drainage pipe 16 connected to the central collecting pipe 21, and then is discharged through the drainage pipe 4.

[0037] When the first group of receiving frames 13 have completed the filtration, the external power supply starts the driving motor 7, so that the driving motor 7 drives the supporting rod 5 to rotate through the belt 6, and the supporting rod 5 drives the central collecting pipe 21, and the central collecting pipe 21 drives the rotating receiving frame 3 to rotate through the guide inclined plate 15, and the rotating receiving frame 3 moves the other group of receiving frames 13 that have not been filtered to the bottom of the pressure component 2, so that the filtration work can be carried out without stopping the machine.

[0038] The receiving frame 13 that has been filtered will gradually rotate downward during the rotation of the rotating receiving frame 3, and the sludge inside it will be exposed to the side of the mounting frame 1. At this time, the receiving filter plate 14 inside the receiving frame 13 can be cleaned directly without disassembling it. A cleaning device can also be set on the side of the mounting frame 1 to directly clean the receiving filter plate 14. At the same time, when the receiving filter plate 14 needs to be disassembled, it can be pulled out from the bottom of the receiving frame 13 to complete the disassembly.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
