Then the water stains in the filter tank can be dried by the heating plate, and the vacuum pump is started to vacuumize, so as to avoid the contact between the material and air or water during filtration, and to keep the inner cavity of the equipment in vacuum state during filtration.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Please refer to Figures 1-4 The utility model provides an embodiment: a solid -liquid separation filtering equipment, including base 1, the upper end of base 1 is provided with cylinder 2, the inside installation of cylinder 2 is equipped with centrifugal mesh cylinder 13, and the bottom of centrifugal mesh cylinder 13 is rotatably connected with cylinder 2, the upper end of one side of cylinder 2 is provided with medium inlet pipe 3, and the export of medium inlet pipe 3 is located above centrifugal mesh cylinder 13, and the lower end of one side of cylinder 2 is provided with liquid outlet pipe 4, the intermediate position in the inside of base 1 is installed with centrifugal motor 16, and the output shaft of centrifugal motor 16 is connected with the shaft of the bottom of centrifugal mesh cylinder 13 through coupling, and the other side of the upper end of base 1 is provided with solid storage tank 11, and one side of solid storage tank 11 is installed with hose 10, and the other end of hose 10 is connected with movable suction pipe 9, and the one end of hose 10 close to solid storage tank 11 is installed with suction pump 12, and the lower end of movable suction pipe 9 is equipped with four annular distribution adsorption holes 15, and one side of solid storage tank 11 is equipped with sealing door.

[0024] When using, centrifugal motor 16 is opened, and the output shaft drives centrifugal mesh cylinder 13 in the inside of cylinder 2 to rotate at high speed, and the solid-liquid mixture in the mesh cylinder is subjected to the action of centrifugal force. Because the density of liquid and solid is different, the centrifugal force they receive is also different, and the centrifugal force received by liquid is small due to its small density, so it is thrown to the outside of the mesh cylinder and flows out through the hole or gap of the mesh cylinder. And the solid is blocked in the inside of the mesh cylinder due to its large density, and the liquid enters into cylinder 2 through centrifugal mesh cylinder 13, and then is discharged from liquid outlet pipe 4, and after centrifugal motor 16 stops, part of the solid in the inside of centrifugal mesh cylinder 13 falls into cleaning plate 14 under the action of gravity, and by opening suction pump 12, negative pressure is kept in movable suction pipe 9 through hose 10, so that the solid can enter into movable suction pipe 9 through adsorption hole 15, and then enter into solid storage tank 11 from hose 10.

[0025] Please refer toFigure 1 and Figure 2 The outer part of the medium inlet pipe 3 and the liquid outlet pipe 4 are both provided with an electric control valve 5, and the electric control valve 5 on the liquid outlet pipe 4 is provided with a flow sensor 6 on one side, the output end of the flow sensor 6 is connected to a single-chip microcomputer, and the output end of the single-chip microcomputer is connected to the electric control valve 5.

When the flow rate is within the set range, the separation and filtration equipment can operate normally. If the flow rate is lower than the set value, it indicates that the amount of liquid passing through the centrifugal filter drum is reduced, and there is a situation of blockage of solid objects inside. At this time, a signal is generated to the single-chip microcomputer, and the medium inlet pipe is stopped by the single-chip microcomputer to stop conveying, and the blocked solid objects are cleaned by the self-cleaning mechanism.

One side of the movable pipe 9 inside the transmission box 7 is provided with a rack 18, the transmission box 7 is rotatably installed with an adjusting gear 17, and the adjusting gear 17 is in meshing connection with the rack 18. The transmission box 7 is provided with a servo motor 8 outside, and the output shaft of the servo motor 8 is fixed with the adjusting gear 17.

[0028] In use, after the centrifugal screen drum blockage detection mechanism closes the electric control valve 5 of the liquid outlet pipe 4, the servo motor 8 is started, the output shaft drives the adjusting gear 17 to rotate, and under the meshing action of the rack 18, the movable pipe 9 is driven to rise.

At the same time, the upper end surface of the cleaning plate 14 is concave, and the solid objects can be accumulated at the bottom of the notch. At this time, the pump 12 is started, not only the blocked solid objects are collected, but also the mesh of the filter screen is ensured to be in an unobstructed state.
