[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4As shown, a sludge treatment mechanism for an integrated sewage treatment device is disclosed, comprising a base 1, a water collection tank 3 and a circular shell 6 fixedly installed on the top of the base 1, a shell 5 fixedly connected to the top of the water collection tank 3, and the shell 5 and the circular shell 6 being fixedly connected, two rollers 20 being symmetrically rotatably connected inside the shell 5, and a filter belt 12 being tensioned and sleeved between the two rollers 20, with side baffles 22 sealingly abutting both sides of the filter belt 12, and multiple limiting strips 21 fixedly connected to the outer surface of the filter belt 12, and the limiting strips 21 also sealingly abutting against the side baffles 22, with rubber strips fixedly connected to both ends of the limiting strips 21 and both ends of the filter belt 12, the rubber strips abutting against the side baffles 22 to ensure a sealing effect.

[0029] An electric pressure plate is fixedly installed on the inner top of the housing 5. The electric pressure plate includes an electric push rod 16, which is fixedly installed on the inner top of the housing 5. The movable end of the electric push rod 16 is fixedly connected to a sludge pressure plate 15, and the two sides of the sludge pressure plate 15 are respectively attached to the inner wall of the adjacent side of the housing 5, so as to squeeze the sludge passing through, so as to discharge most of the water in the sludge.

[0030] The bottom of the filter belt 12 is abutted against a support mesh plate 23, which supports the filter belt 12 and ensures the smooth operation of the squeezing operation. A water collection trough 17 is fixedly sleeved on the outer surface of the support mesh plate 23, and the water collection trough 17 is set through the shell 5 and connected to the water collection tank 3, which is conducive to the collection of sewage.

[0031] The inner side of the circular shell 6 is rotatably connected to a support frame 19. The outer surface of the support frame 19 is fixedly connected to a mesh-type material distribution plate 18. The two sides of the mesh-type material distribution plate 18 are respectively attached to the inner wall of the adjacent side of the circular shell 6. The outer surface of the mesh-type material distribution plate 18 has multiple air holes that penetrate into the interior. The air holes facilitate air circulation and make it easier to dry the sludge in the material trough of the mesh-type material distribution plate 18.

[0032] A synchronous electric drive assembly is installed between the support frame 19 and the single roller 20. The synchronous electric drive assembly includes a motor 14 and two synchronous pulleys 11. The mounting shafts of the two synchronous pulleys 11 are respectively installed through the housing 5 and the circular shell 6. The mounting shafts of the two synchronous pulleys 11 are respectively fixedly connected to the adjacent roller 20 and the support frame 19. The motor 14 is fixedly installed on one side of the outer surface of the circular shell 6 and fixedly connected to the adjacent synchronous pulleys 11. The two synchronous pulleys 11 are meshed with a synchronous belt 13, which can synchronously drive the support frame 19 and the roller 20 to run, reducing the number of drive devices and lowering costs.

[0033] Multiple drying components are fixedly installed on one side of the outer surface of the circular shell 6. Each drying component includes an air duct heater 7, and the air duct heater 7 is fixedly connected to one side of the outer surface of the circular shell 6. A fan 8 is fixedly connected to the air inlet of the air duct heater 7. The air duct heater 7 is a device for heating air. It mainly heats the air in the air duct by converting electrical energy into heat energy. In this application, it can heat the air entering the shell 5.

[0034] Both the outer surface of the shell 5 and the water collection tank 3 are fixedly connected to a drain pipe 2, which facilitates the discharge of sewage.

[0035] A feed hopper 4 is fixedly installed on one side of the top of the shell 5. The feed hopper 4 facilitates the entry of sludge into the shell 5.

[0036] An exhaust pipe 10 is fixedly connected to one side of the top of the round shell 6, and a discharge pipe 9 is fixedly embedded to one side of the bottom of the round shell 6. The exhaust pipe 10 can be connected to existing air filtration equipment to purify the discharged gas and avoid air pollution.

[0037] Working principle: Upon overall startup, the blower 8 and the duct heater 7 operate. The blower 8 draws outside air into the duct heater 7, where it is heated and then conveyed to the mesh-type distribution plate 18, before being distributed to the remaining space of the cylindrical shell 6. The motor 14 drives the connected synchronous pulley 11 intermittently. The synchronous pulley 11, via the synchronous belt 13, drives another synchronous pulley 11 intermittently, thus synchronously driving the roller 20 and support frame 19 to rotate intermittently. The two rollers 20 work together to drive the filter belt 12 to rotate intermittently. Sludge is added to the shell 5 through the feed hopper 4, falling onto the filter belt 12. The sludge is controlled by the limiting strip 21 and side baffle 22. Limiting is performed. Since it operates intermittently, when the sludge reaches a certain amount, it is transported to the bottom of the sludge pressing plate 15. The electric push rod 16 pushes the sludge pressing plate 15 to squeeze the sludge below. The squeezed wastewater enters the water collection tank 17 through the filter belt 12 and the support mesh plate 23, and then enters the water collection box 3. As the equipment operates, when the squeezed sludge moves to the end of the filter belt 12, it will fall into different material troughs of the mesh-type distribution plate 18. The mesh-type distribution plate 18 intermittently drives the sludge to move. At the same time, hot air can dry the intermittently moving sludge. When the sludge moves to the bottom, it will fall under the action of gravity and then be discharged through the discharge pipe 9.

[0038] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the motor 14, fan 8, duct heater 7 and electric push rod 16 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
