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.

[0016] See Figure 1As shown in the illustration, this specific embodiment discloses a filtration, washing, stirring, and drying machine, including a cylinder 1, a drive mechanism 2, a stirring mechanism 3, a heating jacket 4, a vacuum mechanism 5, and a filter plate 6. The drive mechanism 2 is fixed above the cylinder 1 and is connected to the stirring mechanism 3 to drive the stirring mechanism 3 to rotate. The stirring mechanism 3 is located inside the cylinder 1. The heating jacket 4 is located within the inner and outer layers of the cylinder 1. The vacuum mechanism 5 is located above the cylinder 1. The filter plate 6 is located on the side and bottom of the lower middle position inside the cylinder 1, and a corresponding filter pipe joint is provided on the outside of the filter plate 6. Specifically, the upper and lower ends of the heating jacket 4 are provided with the inlet and outlet of the heating source, specifically the inlet and outlet of steam. For better heating, a bottom-inlet and top-outlet configuration can be adopted. The vacuum mechanism 5 uses a vacuum pump or other device connected to the cylinder. Preferably, a dust filter 11 is provided above the cylinder 1, the bottom of which is connected to the inside of the cylinder 1, and the outside of which is connected to the vacuum pump for vacuuming. The filter plate 6 is detachably fixed to the side and bottom of the lower part of the cylinder 1 for easy replacement. Coolant can also be circulated into the heating jacket 4; its heating function is not limited to this purpose, and it can also be circulated with a low-temperature medium for cooling.

[0017] More specifically, the stirring mechanism 3 is a worm gear stirring device. The stirring mechanism 3 includes a hollow shaft 31, worm gear blades 32, worm gear blade connecting rods 33, and a telescopic sleeve rod 34. The upper end of the hollow shaft 31 is located outside the upper end of the cylinder 1. The worm gear blades 32 are located inside the cylinder 1. The worm gear blades 32 are connected to the telescopic sleeve rod 34 through the worm gear blade connecting rods 33. Both ends of the worm gear blade connecting rod 33 are movably connected to the worm gear blades 32 and the telescopic sleeve rod 34, and can be rotated between them. The worm gear blades 32 have a spiral structure. The telescopic sleeve rod 34 is sleeved on the hollow shaft 31. The telescopic sleeve rod 34 and the hollow shaft 31 are slidably connected up and down. The telescopic sleeve rod 34 and the hollow shaft 31 are limited by vertically arranged grooves and protrusions. The lower end of the telescopic sleeve rod 34 is fixed to the lower end of the hollow shaft 31. The upper end of the telescopic sleeve rod 34 is detachably fixed to the hollow shaft 31, for example, by detachable screws. The worm gear blades 32 can fit against the inner wall of the cylinder 1, thus easily scraping off the adhesive material on the inner wall of the cylinder 1. Furthermore, the angle of the worm gear blades 32 can be adjusted by the telescopic and adjustable sleeve 34, thereby adjusting the scraping position to ensure that the material can be scraped throughout the cylinder and eliminating dead corners.

[0018] Preferably, a viewing window 12 is provided on the upper side of the cylinder 1. The condition of the slurry inside can be observed through the viewing window 12, and the adhesion of the powder can be detected. The angle and lead of the worm gear blade 32 can be adjusted according to the observed condition.

[0019] Further preferably, the bottom of the cylinder 1 is provided with a bottom discharge port 13, and the outer interlayer of the cylinder 1 is provided with a heat insulation layer 14. In addition, a pneumatic discharge valve 16 is connected to the outside of the bottom discharge port 13. The pneumatic discharge valve 16 adopts an all-angle discharge method, which can effectively improve the discharge efficiency. And by setting the heat insulation layer, the heating efficiency can be effectively improved.

[0020] As a preferred structure, a rotary joint 15 is connected above the hollow shaft 31 to ensure that the hollow shaft 31 can continue to feed material during rotation.

[0021] As a preferred structure, the lower part of the cylinder 1 is set as a conical structure, which can improve the efficiency of material feeding and mixing.

[0022] The drive mechanism 2 includes a drive motor 21 and a reducer 22. The reducer 22 is connected to the upper end of the hollow shaft 31, and the drive motor 21 and the reducer 22 are connected to each other. Specifically, it can be a gear transmission structure.

[0023] During operation, in the filtration and washing stage, the material is added from the top of the equipment. Inside the machine, it is filtered and dried under pressure or vacuum. Then, washing liquid is added, and the material undergoes multiple automatic re-washing processes using a screw conveyor. After meeting the washing requirements, the material is pressed dry. In the drying stage, the cylindrical jacket, conical jacket, hollow shaft, and hollow screw conveyor simultaneously heat the material. The evaporated water vapor or solvent is removed by vacuum through the top dust filter, achieving the drying purpose. After drying, the bottom valve is opened, automatically discharging the dried powder material from the equipment.

[0024] This invention provides a machine that can perform multiple operations such as filtration, washing, and drying in one unit, offering versatility and low investment costs. It operates in a closed system, making it particularly suitable for processing flammable, explosive, toxic, or highly toxic hazardous products, as well as fresh foods, biological products, and pharmaceuticals where contamination is unacceptable. In the filtration stage, the excellent adhesion and scraping action between the worm gear and the filter media allows for filtration of the material under thin-layer filter cake conditions, resulting in high filtration efficiency. In the washing stage, a special stirring structure ensures uniform stirring characteristics, allowing for thorough resizing and improving washing efficiency. In the drying stage, the cylinder jacket and hollow worm gear simultaneously heat the material, while the worm gear scrapes material off the cylinder wall, further enhancing thermal efficiency. Drying in an airtight environment significantly lowers the solvent's boiling point, facilitating solvent recovery. Furthermore, due to its integrated structure, it allows for fully automated control, reducing labor intensity and providing a better operating environment.
