[0002] A sludge dewatering machine, also known as a sludge dewatering machine or sludge filter press, is a device used to treat sludge generated during wastewater treatment. Its main function is to squeeze out the water from the sludge through mechanical pressure, thereby reducing the sludge volume and moisture content, facilitating subsequent transportation and disposal. Sludge dewatering machines are widely used in urban wastewater treatment plants, industrial wastewater treatment, and other fields, helping to improve sludge treatment efficiency and reduce environmental pollution.

[0003] While current technology offers many advantages, its disadvantages include the need to transfer the dried sludge to the next processing step after the sludge dewatering process is complete.

[0019] The technical advantage of adopting the above-mentioned further solution is that it facilitates the transfer of wet sludge using the sludge pond.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] This invention begins by opening the spiral feed pipe on one side of the sludge dewatering machine body to transfer sludge from the sludge tank into the machine body. The machine body is then started, utilizing the mechanical pressure of its internal components to squeeze out water from the sludge, thus reducing its volume and moisture content. After dewatering, the dry sludge is conveyed to the surface of the conveyor belt body via the threaded feed pipe on the other side of the machine body. The operator then starts the conveyor belt body using a controller, continuously transporting the dry sludge to the next process. After the conveying operation is complete, the operator shuts down the sludge dewatering machine body and the conveyor belt body. The controller then starts motor two, whose output drives the threaded screw to rotate forward. This continuous forward rotation of the threaded screw causes the slider on its surface to initially move vertically upward. The slider then drives motor two and the entire brush cylinder to rise vertically. At this point, a limit post restricts the brush cylinder's movement, preventing it from spinning freely. When the outer surface of the brush cylinder contacts... After contacting the outer surface of the conveyor belt, motor two is then started. Motor two drives the brush cylinder to rotate at high speed, using the high-speed rotation of the brush cylinder to sweep away the mud and dust on the outer surface of the conveyor belt. At the same time, the operator starts the liquid pump. The connecting pipe has been previously connected to the water source, and the liquid pump then transmits water to the conveyor pipe. Multiple high-pressure nozzles are used to spray water onto the outer surface of the conveyor belt, thoroughly removing the mud and dirt. The two long plates are set at a safe spraying distance to prevent damage to the outer surface of the conveyor belt due to high pressure. The conveyor belt is waterproof, and the internal drive mechanism is also waterproof. Therefore, during cleaning, the conveyor belt is restarted to allow it to move slowly, working in conjunction with the cleaning mechanism to quickly clean the surface of the conveyor belt without manual cleaning. This is very convenient and improves the subsequent cleaning function of the sludge conveying device.

[0022] In this invention, during cleaning, the cleaning water is collected inside the anti-splash box, and two baffles prevent the cleaning water from splashing. The height of the two baffles is not close to the outer surface of the conveyor belt body, so they will not cause any impact. In actual use, it is normal for a small amount of water to flow out from the gap between the baffles and the conveyor belt body. When the sewage inside the anti-splash box accumulates to a certain level, the operator starts the transfer pump to transfer the sewage to the drainage facility. The transfer pump can transfer sewage containing mud and dust, thereby achieving anti-splash treatment of the cleaning water when rinsing the surface of the conveyor belt, improving the practicality of the sludge conveying device.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figure 1 - Figure 5This utility model provides a technical solution: a sludge conveying device for a sludge dewatering machine, comprising two vertical plates 1 and a sludge dewatering machine body 118; a conveyor belt body 103 is provided on the inner side of the outer surface of the two vertical plates 1; two connecting rods 101 are fixedly connected to the bottom of the two vertical plates 1; two support plates 102 are fixedly connected to the bottom of each of the two connecting rods 101; hollow plates 109 are fixedly connected to the bottom of each of the two vertical plates 1; threaded screws 110 are movably connected to both sides of the inner wall of one of the hollow plates 109; a motor 111 is fixedly installed at the bottom center of one of the hollow plates 109; the output end of the motor 111 is fixedly connected to the threaded screw 110. At the bottom of 10, a slider 112 is threadedly connected to the outer surface of the threaded screw 110. A motor 113 is fixedly installed on one side of the outer surface of the slider 112. A brush cylinder 114 is fixedly connected to the output end of the motor 113. Limiting posts 116 are fixedly connected to both sides of the inner wall of another hollow plate 109. A slider 115 is movably sleeved on the outer surface of the limiting post 116. The other end of the brush cylinder 114 is movably connected to one side of the slider 115. A long plate 106 is fixedly connected to the bottom of both vertical plates 1. A conveying pipe 107 is fixedly connected to the inner side of the outer surface of the two long plates 106. Multiple high-pressure nozzles 108 are fixedly embedded on the outer surface of the conveying pipe 107.

[0032] In this embodiment, the spiral feed pipe on one side of the sludge dewatering machine body 118 is first opened to transfer the sludge from the sludge tank 119 to the sludge dewatering machine body 118. Then, the sludge dewatering machine body 118 is started. The sludge dewatering machine body 118 uses the mechanical pressure of its internal components to squeeze out the water from the sludge, thereby reducing the sludge volume and lowering the water content. After dewatering, the dry sludge material is conveyed to the surface of the conveyor belt body 103 by the threaded feed pipe on the other side of the sludge dewatering machine body 118. Subsequently, the operator starts the conveyor belt body 103 using the controller. 3. The dried sludge is continuously conveyed to the next process. After the conveying operation is completed, the operator shuts down the sludge dryer body 118 and the conveyor belt body 103. Then, the controller starts the second motor 113. The output end of the second motor 113 drives the threaded screw 110 to rotate forward. Through the continuous forward rotation of the threaded screw 110, the slider 112 located on the surface of the threaded screw 110 begins to move vertically upward. The slider 112 drives the second motor 113 and the brush cylinder 114 to rise vertically as a whole. At this time, the limit post 116 limits the brush cylinder 114 to prevent it from spinning idly. When the outer edge of the brush cylinder 114... After the surface contacts the outer surface of the conveyor belt body 103, motor 2 113 is then started. Motor 2 113 drives brush cylinder 114 to rotate at high speed. The high-speed rotation of brush cylinder 114 sweeps away the mud and dust on the outer surface of the conveyor belt body 103. At the same time, the operator starts liquid pump 104. The connecting pipe 105 has been previously connected to the water source. Then, the liquid pump 104 transmits water to the delivery pipe 107, and multiple high-pressure nozzles 108 spray water onto the outer surface of the conveyor belt body 103 to completely remove the mud and dust. The two long plates 106 have already... The high pressure is set to a safe spraying distance, preventing damage to the outer surface of the conveyor belt body 103. Simultaneously, the brush cylinder 114 and high-pressure nozzle 108 clean the outer surface of the conveyor belt body 103. The conveyor belt body 103 is waterproof, and its internal drive mechanism is also waterproof. Therefore, during cleaning, the conveyor belt body 103 is restarted, allowing for slow transport in conjunction with the cleaning mechanism. This enables rapid cleaning of the conveyor belt surface without manual intervention, greatly simplifying the process and improving the subsequent cleaning capabilities of the sludge conveying device.

[0033] Example 2, as Figures 1-5As shown, a horizontal plate 2 is fixedly connected to one side of the outer surface of each of the two vertical plates 1. A splash shield 201 is fixedly connected to the bottom of the two horizontal plates 2. Two baffles 202 are fixedly connected to the top of the splash shield 201 near the edge. A liquid pump 104 is fixedly installed on one side of the outer surface of the splash shield 201. The output end of the liquid pump 104 is connected to the inside of the conveying pipe 107 through a hose. A connecting pipe 105 is fixedly connected to the input end of the liquid pump 104. A transfer pump 117 is fixedly installed on the other side of the outer surface of the splash shield 201. The input end of the transfer pump 117 is fixedly embedded inside the splash shield 201. A sludge tank 119 is connected to one side of the outer surface of the sludge dewatering machine body 118 through a spiral feed pipe.

[0034] In this embodiment, during cleaning, the cleaning water passes through the anti-splash box 201 and is collected inside the anti-splash box 201. Two baffles 202 prevent the cleaning water from splashing. The height of the two baffles 202 is not close to the outer surface of the conveyor belt body 103, so they will not cause any impact. In actual use, it is normal for a small amount of water to flow out from the gap between the baffles 202 and the conveyor belt body 103. When the sewage inside the anti-splash box 201 accumulates to a certain extent, the operator starts the transfer pump 117 to transfer the sewage to the drainage facility. The transfer pump 117 can transfer sewage containing mud and dust, thereby achieving anti-splash treatment of the cleaning water when rinsing the surface of the conveyor belt, which improves the practicality of the sludge conveying device.

[0035] Working Principle: In operation, first open the spiral feed pipe on one side of the sludge dewatering machine body 118 to transfer the sludge from the sludge tank 119 into the sludge dewatering machine body 118. Then, start the sludge dewatering machine body 118. The machine uses the mechanical pressure of its internal components to squeeze out the water from the sludge, thereby reducing the sludge volume and moisture content. After dewatering, the dry sludge is conveyed by the threaded feed pipe on the other side of the sludge dewatering machine body 118 to the surface of the conveyor belt body 103. Then, the operator starts the conveyor belt body 103 using the controller, continuously transporting the dry sludge to the next process. After the conveying operation is completed, the operator shuts off the sludge dewatering machine body 118 and the conveyor belt body. The conveyor belt body 103 is then started by the controller, and the output end of the second motor 113 drives the threaded screw 110 to rotate forward. Through the continuous forward rotation of the threaded screw 110, the slider 112 located on the surface of the threaded screw 110 begins to move vertically upward. The slider 112 drives the second motor 113 and the brush cylinder 114 to rise vertically as a whole. At this time, the limit post 116 limits the brush cylinder 114 to prevent it from spinning idly. When the outer surface of the brush cylinder 114 contacts the outer surface of the conveyor belt body 103, the second motor 113 is then started. The second motor 113 drives the brush cylinder 114 to rotate at high speed, using the high-speed rotation of the brush cylinder 114 to sweep away the dirt and dust from the outer surface of the conveyor belt body 103. Simultaneously, the operator starts the hydraulic system. Pump 104 and connecting pipe 105 were previously connected to a water source. Water is then pumped through pump 104 to delivery pipe 107, and multiple high-pressure nozzles 108 spray water onto the outer surface of the conveyor belt body 103 to thoroughly remove mud and impurities. Two long plates 106 are set at a safe spraying distance to prevent damage to the outer surface of the conveyor belt body 103 due to high pressure. Simultaneously, a brush cylinder 114 and high-pressure nozzles 108 clean the outer surface of the conveyor belt body 103. Since the conveyor belt body 103 is waterproof, and its internal drive mechanism is also waterproof, the conveyor belt body 103 is restarted during cleaning, allowing for slow transport. In conjunction with a cleaning organization, the surface of the conveyor belt can be cleaned quickly without manual intervention, which is very convenient and improves the subsequent cleaning function of the sludge conveying device. During cleaning, the cleaning water is collected inside the anti-splash housing 201, and two baffles 202 prevent the cleaning water from splashing. The height of the two baffles 202 is not in close contact with the outer surface of the conveyor belt body 103, so it will not cause any impact. In actual use, it is normal for a small amount of water to flow out from the gap between the baffles 202 and the conveyor belt body 103. When the sewage inside the anti-splash housing 201 accumulates to a certain level, the operator starts the transfer pump 117 to transfer the sewage to the drainage facility.The transfer pump 117 can transfer wastewater containing mud and dust, thereby preventing splashing of cleaning water during the rinsing of the conveyor belt surface and improving the practicality of the sludge conveying device.
