Filtering, cleaning, drying three-in-one device

[0014] Such as figure 1 As shown, the three-in-one filter, washing and drying equipment of the present invention consists of a chassis 1, a tank body 18, a leg 4, and a support 6 to form a sealed and pressure-bearing cavity, which is convenient for materials For access and maintenance, takeover accessories such as manhole 15, cleaning ball 7 are also installed, the outer wall of the tank 18 and the outside of the chassis 1 are installed with an insulation layer 20, and a filter disc 2 is installed on the bottom of the tank 18 above the chassis 1, which can be used The metal sintered plate, the chassis 1 and the tank 18 are connected by the chassis lifting hydraulic cylinder 5, which facilitates the replacement and cleaning of the filter disc 2; a set of agitators is installed on the upper head of the tank, which is composed of mixing blades 3 and agitating The shaft 16, the bellows 17, the frame 9, the mixing lifting hydraulic cylinder 10, and the support 11. The mixing shaft 16 is sealed with the tank through a mechanical seal 8. The explosion-proof motor 12 and the reducer 13 drive the agitator to rotate to realize the mixing function. The lifting hydraulic cylinder 10 drives the stirring shaft to rise and fall. A hydraulic discharge device 21 is installed on the side of the bottom of the tank. The agitator has a hollow structure and can be used for heating. Its water inlet and outlet ports N5 and N6 are installed on the top of the stirring shaft 16 through a rotary joint 14; the tank 18 A coil heater is wound on the side wall, made of half pipe 19, the hot water inlet and outlet are respectively N3 and N4; the hot water inlet and outlet of the bottom heater are respectively N1 and N2.

[0015] Working principle: The suspension to be filtered is added to the three-in-one equipment of filtration, washing and drying. When feeding, the bottom is vacuumed or the tank is pressurized to make the filtration proceed. The solid-liquid separation is achieved through the metal sintered plate at the bottom of the tank. The filter plate and filter hole diameter of the corresponding form can be selected according to the different filter media. When the liquid disappears, the agitator starts to rotate and descend, and the stirring blade presses on the filter cake with appropriate force, and it slows down as the height of the filter cake decreases. Decrease and smooth the filter cake to make the filtration process continue.

[0016] The washing ball is passed into the washing liquid, and the stirring blade is continuously lowered to mix the filter cake and washing liquid layer by layer, and finally a suspended filter cake is formed to achieve sufficient washing.

[0017] The drying of the filter cake is heated by the bottom plate, the side wall of the equipment, and the agitator at the same time, and the moisture is quickly evaporated to achieve the drying effect.

[0018] The material is discharged through the mixing blade to push the material backward, and the material is automatically discharged through the hydraulic discharge device.

[0019] The invention realizes the functions of filtering, washing and drying materials in a closed environment. While realizing the continuous process, since the equipment is closed, no harmful gas will be emitted, and no harm will be caused to the operators; the material is discharged through The mixing blade reversely pushes the material, and the material is automatically discharged through the hydraulic discharge device. Compared with the manual discharge device, the labor intensity of the workers is greatly reduced.
