As shown in fig. 1-2, a drug filtering tank comprises a tank body 1, wherein an outer net barrel 2 and an inner net barrel 3 are arranged in the tank body 1. As shown in fig. 10, the outer mesh cylinder 2 and the inner mesh cylinder 3 are disposed in an inner and outer sleeve manner, and the portion of the inner mesh cylinder 3 extending out of the outer mesh cylinder 2 is a thin-walled solid structure, and the portion of the side wall of the inner mesh cylinder 3 located in the outer mesh cylinder 2 is a thin-walled structure with holes. And the outer mesh cylinder 2 is a thin-walled and perforated tubular structure.

As shown in fig. 1 and 6, specifically, the inner net barrel 3 includes an inner net barrel 3-1, an end cover 3-2 is hinged to the upper end of the inner net barrel 3-1, the other end of the end cover 3-2 is locked with the inner net barrel 3-1 by a bolt, and the inner net barrel can be conveniently opened through the hinged relationship. The internal structure is convenient to mount and dismount. The inner net barrel 3 is internally provided with support plates 3-3 at the upper and lower parts, the support plates 3-3 are internally and externally provided with two annular grooves 3-4, and the upper and lower ends of the two filter net barrels 3-5 are inserted into the corresponding annular grooves 3-4 to form a clamping connection relationship. The meshes of the filter screen cylinder 3-5 at the inner ring are larger than the meshes of the filter screen cylinder 3-5 at the outer ring. When in installation, the end cover 3-2 can be opened, the supporting plate 3-3 is placed to the bottom of the inner net cylinder 3-1, then the filter net cylinder 3-5 is installed, the supporting plate 3-3 is inserted into the upper end of the filter net cylinder 3-5, and finally the end cover 3-2 is covered and locked to realize the compact installation.

As shown in fig. 8, the lower end of the inner screen cylinder 3 is communicated with a liquid inlet pipe 6, the liquid inlet pipe 6 is rotatably connected with a pipe head 7 through a bearing, and the pipe head 7 extends out of the tank body 1 and is hermetically connected with a main pipe 8 through a flange plate and keeps a communicated state. The main pipe 8 can be introduced with the liquid medicine to be filtered through the corresponding pump body.

As shown in fig. 9, the upper end of the inner mesh cylinder 3 is fixed with a rotating shaft 4, the rotating shaft 4 is rotatably connected with the tank body 1 through a bearing, the rotating shaft 4 extends out of the tank body 1 and is connected with a motor 5 through a coupler, and the inner mesh cylinder 3 can be driven to rotate circumferentially through the motor 5.

As shown in fig. 4, the outer net cylinder 2 is tubular and includes an upper outer net cylinder part 2-1, a middle outer net cylinder part 2-2 and a lower outer net cylinder part 2-3, wherein the inner diameters of the upper outer net cylinder part 2-1 and the lower outer net cylinder part 2-3 are smaller than and the same as the middle outer net cylinder part 2-2, and the upper outer net cylinder part 2-1 and the lower outer net cylinder part 2-3 are in clearance fit with the inner net cylinder 3 and are not affected by the rotation of the inner net cylinder 3. And because the diameter of the middle part 2-2 of the outer net barrel is larger, an interval exists between the middle part 2-2 of the outer net barrel and the inner net barrel 3, and a quartz sand layer 2-8 is arranged in the interval. In order to facilitate the replacement of the quartz sand, an inlet pipe 2-4 and an outlet pipe 2-5 can be respectively arranged at the upper part and the lower part of the middle part 2-2 of the outer net cylinder, wherein the inlet pipe 2-4 and the outlet pipe 2-5 are solid pipes, extend out of the tank body 1 and are fixedly connected with the tank body 1 through ear plates. Wherein the end of the inlet pipe 2-4 is provided with a rubber plug 2-6, and the rubber plug 2-6 is used for opening and closing the inlet pipe 2-4. And a T-shaped plug rod 2-7 is arranged at the communicating part between the inside of the outlet pipe 2-5 and the middle part 2-2 of the outer mesh cylinder, the T-shaped plug rod 2-7 comprises a pull rod, the top end of the pull rod is provided with a limit plate, the lower end of the limit plate is provided with a piston, and the inner diameter of the piston is the same as that of the outlet pipe 2-5. In general, the T-shaped plug rod 2-7 is pressed against the outlet pipe 2-5 by the gravity of the quartz sand so that the outlet pipe 2-5 is closed, and when the quartz sand needs to be poured out, the T-shaped plug rod 2-7 is pushed upwards so that the outlet pipe 2-5 is opened, so that the quartz sand can be gradually poured out. Therefore, the quartz sand can be conveniently replaced or supplemented.

The can body 1 here comprises a can body 1-4 and a can lid 1-5, the edges of the can body 1-4 and the can lid 1-5 being secured by flange bolts. One side of the tank body 1 is provided with liquid outlet pipes 1-3, and the filtered liquid medicine can flow out from the liquid outlet pipes 1-3. The filtering piece between the tank body 1 and the outer mesh cylinder 2 is a honeycomb ceramic filtering body 1-1, and the honeycomb ceramic filtering body 1-1 is tubular and is fully distributed with mutually communicated holes 1-2 along the axial line and the radial direction. The structure can play a role in further filtering.

The working principle and the process are as follows: the motor 5 drives the inner net barrel 3 to rotate, when the liquid medicine enters the inner net barrel 3 through the main pipe 8, as the inner net barrel 3 is internally provided with a plurality of filter net barrels 3-5, the residue and the liquid medicine can be quickly separated through the centrifugal effect generated by quick rotation. And because the filter screen cylinders 3-5 are tubular, the contact area can be increased and the separation is accelerated. Because the upper part and the lower part of the inner net cylinder 3 are solid parts, liquid enters the quartz sand layers 2-8 through the side wall of the inner net cylinder 3, fine residues are filtered and intercepted, then the liquid comes out from the outer net cylinder 2 and enters the honeycomb-shaped ceramic filter body 1-1 for further filtration, finally solid particles in the medicine are completely removed, the purity of the medicine is ensured, and finally the liquid flows out from the liquid outlet pipe 1-3 for next operation.

When the filter screen cylinder needs to be cleaned or replaced after working for a period of time, the motor 5 can be detached, the tank cover 1-5 can be opened, the end cover 3-2 can be opened, and then the filter screen cylinder 3-5 can be taken out for cleaning. The honeycomb ceramic filter body 1-1 can be taken out after the cover is opened. The quartz sand layers 2-8 can be replaced under the ordinary state.
