[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4In the utility model, a pharmaceutical air purification filter includes a shell 1, the top of the shell 1 is fixedly connected with an upper clamping block 2 by bolts, a high-pressure fan 3 is fixedly installed on the upper clamping block 2, an air inlet duct 4 is fixedly connected to the bottom of the high-pressure fan 3, two filter core plates 5 are fixedly connected to the bottom of the upper clamping block 2, the bottom end of the air inlet duct 4 extends between the two filter core plates 5, two pressure pieces 6 are installed inside the shell 1, and the opposite sides of the two pressure pieces 6 are in contact with the two filter core plates 5 respectively, a discharge pipe 7 is fixedly installed at the bottom of the shell 1, and the top of the discharge pipe 7 extends between the two filter core plates 5, two air guide pipes 10 are fixedly connected to the bottom of the shell 1, and a spiral conduit 11 is fixedly connected between the bottom ends of the two air guide pipes 10.

[0022] In the present invention, the shell 1 is used as the main body of the device. The high-pressure fan 3 on the top is first started to pressurize the air and rush it into the space between the two filter plates 5 through the air inlet duct 4. As the internal pressure increases, the pressure pieces 6 on both sides are pushed open to both sides. As the pressure pieces 6 are compressed and expanded to both sides, the air ducts 10 on both sides are connected with the internal space. The air filtered by the filter plates 5 is discharged through the two air ducts 10 and discharged through the spiral conduit 11 to achieve filtration. As the filtration time increases, more dust accumulates on the filtration surface between the opposite sides of the two filter plates 5. When cleaning is needed, the two air ducts 10 are closed first, and the high-pressure fan 3 is kept running at this time. Then the discharge pipe 7 is opened. At this time, due to the two pressure Because the discharge pipe 7 is opened, the intermediate pressure of the force piece 6 is reduced, and the two pressure pieces 6 are reset instantly, and the air between the pressure piece 6 and the filter element plate 5 is squeezed in the opposite direction to back-blow the filter element plate 5 to achieve cleaning, and with the blowing of the high-pressure fan 3, the back-blown dust is blown out of the discharge pipe 7 and discharged, thereby achieving the advantages of more efficient dust cleaning of the device, no need for disassembly for cleaning, and easy operation. This solves the problem in the prior art that more dust will accumulate on the surface of the filter screen, which will lead to a decrease in purification efficiency and air passing efficiency, and requires a long time to clean. Generally, the equipment needs to be disassembled to remove the filter element for cleaning, and its operating efficiency is low. Moreover, the disassembly and assembly takes a long time, which affects the operating efficiency of the equipment.

[0024] In the present invention, the two guide rods 62 are elastically supported by the springs 61, and the two pressure plates 63 are pushed to both sides by the injected high-pressure air and push the guide rods 62 to squeeze the springs 61, so as to achieve the unfolding and pressure-maintaining state, which is convenient for the subsequent reset instant back-blowing cleaning, and the collision is achieved at the moment of contact to make the filter element plate 5 vibrate, so as to achieve a better cleaning effect.

[0025] See also Figure 2 and Figure 3 , wherein: a notch 631 is provided on the side of the bottom of the pressing plate 63 contacting the filter element plate 5 , and the notch 631 is movably matched with the top end of the air guide pipe 10 .

[0026] In the present invention, the notch 631 allows the pressing plate 63 to be moved to a certain extent before being connected to the air duct 10 , so as to maintain a sufficient distance between the pressing plate 63 and the filter element plate 5 .

[0027] See also Figure 1 , wherein: the air guide pipe 10 and the discharge pipe 7 are both fixedly installed with a solenoid valve 8 .

[0028] In the present invention, the electromagnetic valve 8 is used to conveniently control the opening and closing of the air guide pipe 10 and the discharge pipe 7, so as to facilitate the switching operation and ash discharge and cleaning.

[0029] See also Figure 1 , wherein: the spiral conduit 11 is sleeved on the outside of the discharge pipe 7, and the bottom end of the spiral conduit 11 extends horizontally to one side.

[0030] In the present invention, the spiral guide tube 11 is spirally wound around the outer side of the discharge pipe 7, so that the device structure is reasonably and stably arranged.

[0031] See also Figure 1 , wherein: a one-way valve 9 is fixedly installed inside the air inlet duct 4.
