[0002] A mud cake dewatering machine is a device used for solid-liquid separation, commonly used in environmental protection, chemical, pharmaceutical, and food processing industries. It dehydrates mud cakes containing high moisture content, increasing their solids content, reducing subsequent processing load, and saving costs. Its working principle typically combines mechanical pressing and vacuum suction. When the moisture-containing mud cake enters the dewatering machine, it is first subjected to mechanical pressing. Special pressing plates apply pressure to the mud cake, squeezing out the water. Then, a vacuum device generates negative pressure to remove the squeezed-out water, further achieving dewatering of the mud cake.
[0003] The main components of a mud cake dewatering machine include a feeding device, a pressing device, a vacuum device, and a control device. The feeding device is used to feed the mud cake into the dewatering machine; the pressing device includes pressing plates and an adjusting device, which is used to press the mud cake; the vacuum device consists of a vacuum pump, a vacuum bag, and pipes, which is used to remove moisture from the mud cake; and the control device is used to control the entire dewatering process.
[0004] The application of sludge cake dewatering machines is becoming increasingly widespread in my country. They not only help improve the efficiency of solid waste treatment and reduce treatment costs, but also help reduce environmental pollution, which is in line with my country's requirements for energy conservation, emission reduction and the development of a circular economy.
[0005] Existing low-temperature vacuum drying and dehydration devices suffer from poor heat preservation performance during the drying process of mud cakes. This leads to increased heat loss and reduces the efficiency of vacuum drying of mud cakes. Furthermore, the device cannot clean the filter cloth in subsequent operations, causing the filter cloth to remain dirty for extended periods and easily become clogged, further impacting the efficiency of subsequent processing. Summary of the Invention

[0062] Mounting bracket 22, two mounting brackets 22 are provided, and both mounting brackets 22 are fixedly connected to the bottom end of the movable frame 20;
[0063] Two spiral stirring blades 24 are provided, and the two spiral stirring blades 24 are respectively rotatably connected to the two ends of the two mounting brackets 22;
[0064] The second cleaning brush 25 is provided in two parts, and the two second cleaning brushes 25 are respectively rotatably connected to the inner walls on both sides of the two mounting brackets 22.
[0065] Cleaning tube 29, two cleaning tubes 29 are provided, and the two cleaning tubes 29 are rotatably connected to the circumferential surface of the two low temperature traps 15 respectively. The two second cleaning brushes 25 are hollow. The output end of the third motor 21 is fixedly connected to the circumferential surface of one of the spiral stirring blades 24.
[0066] The transmission assembly is used to drive the spiral stirring blades 24 to rotate, and the transmission assembly is used to drive the two spiral stirring blades 24 to rotate synchronously.
[0067] In this embodiment: the movable cleaning frame 16 is fixed to the top of the movable block 5, serving as a support platform for the cleaning components. The limiting grooves 602 at both ends are cleverly designed to ensure stable guidance and position control during the cleaning process. The nut 18 is embedded in the movable block 5 and threadedly connected to the lead screw 17. This mechanical linkage mechanism allows the entire cleaning frame, including the movable cleaning frame 16, to move precisely up and down along the lead screw 17 under the drive of the first motor 4, improving the flexibility and accuracy of the cleaning operation. The movable frame 20 achieves sliding movement through four cylinders 601, which not only increases the stability of the device but also allows for fine adjustments to the cleaning process for different areas. The integration of the third motor 21 provides a power source for subsequent dynamic components. Two mounting brackets 22 are fixed to the bottom of the movable frame 20, each connected to a pair of spiral... The stirring blades 24 are designed to rotate synchronously under the drive of the third motor 21, effectively removing residues from the filter screen and maintaining good permeability. Two sets of second cleaning brushes 25 are rotatably mounted on the inner wall of the mounting frame 22, working in conjunction with the cleaning tube 29. Through their perforated design, they directly act on the surface of the low-temperature trap 15, further enhancing the cleaning effect. The transmission component, as the core drive unit, ensures that the spiral stirring blades 24 work in unison. Through precise transmission ratios and reliable mechanical structures, it guarantees the high efficiency and continuity of the cleaning process, which is a key factor in maintaining the high-efficiency operation of the entire cleaning device.

[0068] Please refer to the details. Figures 1-3 The transmission components include:
[0069] The fourth gear 27, there are two fourth gears 27, and the two fourth gears 27 are respectively fixedly connected to the circumferential surface of the two second cleaning brushes 25;
[0070] The toothed belt 28 and the second cleaning brush 25 are connected to the circumferential surfaces of the two fourth gears 27 through a transmission meshing connection.
[0071] The cleaning component is located on the lower side of the second limiting plate 7. The cleaning component is used to remove dust, dirt and other residues inside the vacuum tank 14.
[0072] In this embodiment: each fourth gear 27 is precisely fixed to the circumferential surface of the second cleaning brush 25. Through this direct connection, the rotational power of the motor can be transmitted to the cleaning brush without loss, realizing the directness and efficiency of power transmission. The toothed belt 28 is tightly engaged between the two fourth gears 27 to form a closed transmission link. This ensures that when the third motor 21 drives one spiral stirring blade 24 to rotate, the other rotates synchronously through the synergistic effect of the toothed belt 28 and the fourth gear 27, ensuring the balance and symmetry of the cleaning action and improving the cleaning coverage and efficiency. The cleaning component is located on the lower side of the second limiting plate 7 and is specially designed to purify the internal environment of the vacuum tank 14. It effectively removes dust, dirt and other residual substances that may affect subsequent operations accumulated during the vacuum drying process through physical or chemical means.
[0073] Please refer to the details. Figure 2 The cleaning components include:
[0074] The first gear 702 is fixedly connected to the output end of the second motor 701;
[0075] Connecting pipe 9 is fixedly connected inside the limiting sleeve 23;
[0076] The second gear 703 is rotatably connected to the circumferential surface of the connecting pipe 9, and the connecting pipe 9 is rotatably connected to the circumferential surface of the second gear 703.
[0077] The first cleaning brush 704 is provided in multiple ways, and the multiple first cleaning brushes 704 are respectively fixedly connected to the circumferential surface of the first gear 702.
[0078] The third gear 26, there are four third gears 26, and the four third gears 26 are respectively fixedly connected to the circumferential surfaces of the two second cleaning brushes 25 and the two spiral stirring blades 24.
[0079] In this embodiment: the first gear 702 is directly connected to the output end of the second motor 701, serving as the starting point of the power source. Its rotation drives the coordinated work of a series of subsequent cleaning components. The second gear 703 is rotatably connected to the circumferential surface of the connecting pipe 9. The first cleaning brush 704 is fixed to the circumferential surface of the first gear 702. These brushes move with the rotation of the gear and directly participate in wiping and cleaning the inner surface of the vacuum tank 14. In addition, the detailed description of the cryogenic trap 15 shows its position in the device and how it is integrated with the transfer pipe 10, emphasizing the detailed considerations of the material processing stage: the discharge end of the cryogenic trap 15 is connected to the subsequent processing steps through the transfer pipe 10. To avoid heat loss or external temperature interference, the outer surface of the transfer pipe 10 is covered with a heat-insulating membrane 8. This setting helps to maintain the temperature stability of the material during the transfer process and is an indispensable part of the entire cryogenic vacuum drying and dehydration process, especially important for heat-sensitive materials.
[0080] Please refer to the details. Figures 1-6 The discharge port of the low-temperature collector 15 is fixedly connected to a transmission pipe 10, and a heat-insulating diaphragm 8 is fixedly connected to the circumferential surface of the transmission pipe 10.
[0081] In this embodiment, the transfer pipe 10 serves as a bridge between the cryogenic trap 15 and subsequent processing stages. Its direct connection to the discharge port ensures that the material treated in the vacuum can quickly and continuously enter the next stage, reducing the time exposed to uncontrolled environments. This is crucial for maintaining the continuity and efficiency of material processing. The thermal insulation diaphragm 8, fixed to the circumferential surface of the transfer pipe 10, plays a vital role in thermal insulation. The selected thermal insulation diaphragm 8 material typically possesses low thermal conductivity, good flexibility, and weather resistance, effectively preventing the influence of external ambient temperature on the internal material temperature and the loss of the internal low-temperature environment under complex working conditions. This is of paramount protective significance for materials susceptible to temperature fluctuations, especially biological products, pharmaceutical raw materials, or temperature-sensitive chemicals, ensuring the stability and purity of product characteristics. This setup maintains a constant low temperature state for the material during transmission, reducing changes in physical or chemical properties caused by temperature fluctuations, thereby improving the quality and consistency of the finished product. Furthermore, the application of the thermal insulation diaphragm 8 contributes to energy conservation and emission reduction, as it reduces the demand for external energy to maintain the low-temperature environment of the material, meeting the requirements of modern industry for efficient and environmentally friendly production.
[0082] Please refer to the details. Figures 1-3 The four third gears 26 mesh with each other.
[0083] In this embodiment, each third gear 26 is configured to mesh with the other three gears to form a closed gear chain. When the second cleaning brush 25 or the spiral stirring blade 24 at any end is driven to start rotating by the third motor 21 or the second motor 701, the force will be instantly transmitted to the remaining cleaning brushes and stirring blades through the precise coordination of the third gear 26 group, causing all related components to move synchronously. Whether it is the cleaning or stirring process, a high degree of coordination and consistency is maintained.
[0084] The working principle and usage process of this invention are as follows: First, water-containing materials such as mud cake are fed into the dewatering device through the feeding device. The pressing device in the device then applies mechanical pressure to the material, squeezing out some water through the pressing plates. Vacuum drying process: Next, the vacuum device is activated, and a negative pressure environment is generated by the vacuum pump to further accelerate the evaporation of water in the material. The radiant heating device 11 provides heat when necessary to promote rapid evaporation of water. At the same time, the low-temperature collector 15 captures and condenses the evaporated water, ensuring the recycling and efficiency of heat. The filter cloth is cleaned by the partition. Cleaning: During this process, a specially designed cleaning mechanism 6 automatically performs the cleaning task of the filter cloth. The cleaning mechanism 6 includes components such as a movable cleaning frame 16, a spiral stirring blade 24, and a second cleaning brush 25. Driven by a third motor 21, the movable cleaning frame 16 moves up and down along the limit rod 301 under the cooperation of the lead screw 17 and the nut 18, while the spiral stirring blade 24 and the cleaning brush rotate under the drive of the third motor 21, cooperating with the cleaning tube 29 to ensure comprehensive cleaning of the filter cloth, prevent clogging, maintain high-efficiency filtration performance, and ensure power transmission and synchronization. Control: The transmission assembly ensures the synchronous movement of the spiral stirring blade 24 and the cleaning brush. The transmission assembly includes a fourth gear 27, a toothed belt 28, etc. When the third motor 21 drives one spiral stirring blade 24, the other stirring blade rotates synchronously through the meshing of the toothed belt 28 and the fourth gear 27, achieving balanced cleaning. In addition, the first motor adjusts the position of the limit plate through the lead screw 17, and the second motor 701 directly drives the first gear 702, transmitting power to the first cleaning brush 704 through the second gear 703 and the connecting pipe 9 to clean the inside of the vacuum tank 14. Cleaning, material transfer and heat preservation: The discharge end below the low-temperature collector 15 is connected to the transfer pipe 10, which is covered with a heat-insulating membrane 8 to ensure that the material temperature is constant during the transfer process and avoid heat loss. This is especially important for heat-sensitive materials, such as biological products and pharmaceuticals, and helps to maintain product quality and purity. Control and monitoring: The entire drying and dehydration process is monitored by a control device to ensure that various parameters such as temperature, pressure, motor operation, and material flow are executed according to the predetermined program to achieve the best dehydration effect. At the same time, it responds to real-time conditions and makes necessary adjustments.
[0085] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
