Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides an anti-clogging filtering device for a dehumidifier used for producing trace element fertilizers, comprising a filtering part 1, an air inlet pipe 3 and a connecting pipe 2, wherein the air inlet pipe 3 is arranged on the top of the filtering part 1, the connecting pipe 2 is arranged on the bottom of the filtering part 1, and the filtering part 1 is connected to the air inlet end of the dehumidifier used for producing trace element fertilizers through the connecting pipe 2. When the dehumidifier used for producing trace element fertilizers is working, the outside air enters the filtering part 1 through the air inlet pipe 3, the filtering part 1 filters the air, and the filtered air enters the dehumidifier through the connecting pipe 2, so that the dehumidifier can be prevented from being blocked by dust.

[0025] Filter tanks 4 are evenly arranged in the inner cavity of the filter part 1, and a sealing plate 7 is movably connected in the inner cavity of the filter tank 4, and sealing gaskets are fixed on the side of the filter tank 4 close to the air inlet pipe 3 and the side close to the connecting pipe 2. The two sealing gaskets can be used together to seal the filter tank 4 to prevent dust from entering the filter tank 4.

[0026] The sealing gasket includes a sealing airbag 8 adapted to the inner cavity of the filter tank 4, the sealing airbag 8 is fixedly connected to the filter tank 4, an expansion strip 11 is fixed to the side of the sealing airbag 8 away from the blocking plate 7, the inner cavity of the expansion strip 11 is connected to the inner cavity of the sealing airbag 8, an expansion cavity 10 is provided on the tank wall of the filter tank 4, the expansion strip 11 is located in the expansion cavity 10, the expansion strip 11 is movably connected to the inner cavity of the expansion cavity 10, and the size of the expansion cavity 10 is larger than the size of the expansion strip 11, and the size of the expansion cavity 10 is designed according to demand and is not limited here. Through the setting of the expansion cavity and the expansion strip 11, under the extrusion of external force, the air in the sealing airbag 8 can enter the expansion strip 11, and the restriction on the sealing airbag 8 is released. The resilience of both the expansion strip 11 and the sealing airbag 8 can restore the sealing airbag 8 to its original state, which is convenient for using the sealing airbag 8 to seal the filter tank 4. In some embodiments of the present application, the sealing airbag 8 and the expansion strip 11 are both made of rubber.

[0027] One end of the filter tank 4 is provided with an opening, and the cross section of the opening is smaller than the cross section of the filter tank 4. With this arrangement, the filter tank 4 can limit and position the blocking plate 7. A fixing bolt 6 is bolted to the side of the filter tank 4 near the opening. The blocking plate 7 is a hollow structure. A plug hole 17 is provided on the side of the inner cavity of the blocking plate 7 near the fixing bolt 6. The fixing bolt 6 is adapted to the plug hole 17, and when the plug hole 17 and the fixing bolt 6 are aligned, the fixing bolt 6 can be used to fix the position of the blocking plate 7. At this time, the top of the blocking plate 7 is in a tightly fitted state with the filter tank 4, and the plug plate 7 can be used to block the opening to prevent the gas in the filter part 1 from overflowing.

[0028] The outer surface of the blocking plate 7 is wrapped with a sealing gasket, the material of which may be rubber. The provision of the sealing gasket can improve the sealing effect of the blocking plate 7 on the opening.

[0029] A filtering structure is movably connected in the inner cavity of the opening, and the filtering structure includes a mesh frame 5. A filter screen 9 is provided in the middle of the mesh frame 5, and the filter screen 9 is an arc-shaped structure. The end of the filter screen 9 close to the air inlet pipe 3 is recessed inward, and compared with the flat filter screen 9, the filtering area thereof is increased. The outer diameter of the filter screen 9 is the same as the inner diameter of the filter part 1, and the filter screen 9 will not be touched during the mesh frame 5 entering and exiting the opening, thereby preventing dust adhered to the filter screen 9 from falling into the device due to being touched, and the dust falling from the filter screen 9 can be collected in the recessed part of the filter screen 9, thereby further preventing dust from falling into the dehumidifier during the replacement of the filter screen 9.

[0030] One end of the mesh frame 5 is connected to the sealing plate 7 through a connecting structure, and the other end of the mesh frame 5 is provided with a handle. A threaded hole 18 adapted to the fixing bolt 6 is provided on the side of the other end of the mesh frame 5 close to the fixing bolt 6, and when the mesh frame 5 is connected to the sealing plate 7, the distance between the threaded hole 18 and the sealing plate 7 is the same as the distance between the fixing bolt 6 and the end of the filter tank 4 away from the opening, that is, when the sealing plate 7 is tightly fitted to the end of the filter tank 4 away from the opening, the fixing bolt 6 and the threaded hole 18 can be aligned, and the position of the mesh frame 5 can be fixed by the fixing bolt 6, and at this time the handle is located outside the filter part 1.

[0031] The connection structure includes a fixed block 13 fixedly connected to the net frame 5 and a movable frame 14 movably connected to the inner cavity of the blocking plate 7. The end of the movable frame 14 away from the insertion hole 17 is fixedly connected to the blocking plate 7 through a spring 12. Under the action of external force, the position of the movable frame 14 in the insertion hole 17 can be changed. A through rod 16 is fixedly connected to the middle of the inner cavity of the movable frame 14. A groove 19 adapted to the fixed block 13 is provided at the top of the inner cavity of the blocking plate 7. The fixed block 13 can be inserted into the inner cavity of the blocking plate 7 through the groove 19. When the fixed block 13 is inserted into the inner cavity of the blocking plate 7, the through hole provided in the middle of the fixed block 13 is aligned with the through rod 16. The length difference between the movable frame 14 and the through rod 16 is not less than the length of the through hole. Under the action of external force, the through rod 16 can be separated from the through hole, releasing the restriction on the movable frame 14. Under the action of the rebound force of the spring 12, the through rod 16 can be inserted into the through hole to achieve rapid fixation of the sealing plate 7 and the mesh frame 5.

[0032] In some embodiments of the present application, the connection structure includes two fixed blocks 13 and two movable frames 14. Fixed blocks 13 are fixed on both sides of the end of the net frame 5 away from the handle, and movable frames 14 are movably connected to both sides of the inner cavity of the sealing plate 7. The two movable frames 14 are connected by a connecting rod 15.

[0033] It can be known from the above description that when the fixing bolt 6 is inserted into the inner cavity of the blocking plate 7 through the insertion hole 17, the fixing bolt 6 can squeeze the moving frame 14, and the moving frame 14 drives the through rod 16 connected thereto to move, so that the through rod 16 is away from the groove. Therefore, the fixing block 13 can be inserted into the blocking plate 7 through the groove, which is convenient for fixing the blocking plate 7 and the screen frame 5, or the restriction of the through rod 16 on the fixing block 13 is released, which is convenient for separating the blocking plate 7 from the screen frame 5, and convenient for cleaning or replacing the filter screen 9.

[0034] There are three filter slots 4 mentioned above, and two adjacent filter slots 4 are vertically distributed, and there are two filter screens 9. The mesh diameter of the filter screen 9 close to the air inlet pipe 3 is larger than the mesh diameter of the filter screen 9 close to the connecting pipe 2. The present application adopts a multiple filtration method for the air, which reduces the probability of a single filter screen 9 being blocked, extends the service life of the filter screen 9, and when replacing the filter screen 9, the dehumidifier does not need to be shut down, thereby ensuring the working efficiency of the dehumidifier.

[0035] To sum up: when the anti-blocking filter device for the dehumidifier used for the production of trace element fertilizers is in use, the end of the connecting pipe 2 away from the filter part 1 is connected to the air inlet end of the dehumidifier used for the production of trace element fertilizers, and the filter part 1 is in a vertical state. When the dehumidifier used for the production of trace element fertilizers is working, the outside air enters the inner cavity of the filter part 1 through the air inlet pipe 3, and the filter net 9 in the filter part 1 intercepts the dust in the air. The filtered air enters the dehumidifier through the connecting pipe 2 to prevent the dehumidifier from being blocked by dust in the air. When the filter structure needs to be replaced, the staff takes another filter structure that is the same as the filter structure to be replaced, and inserts the other filter structure into the vacant opening until the mesh frame 5 in the other filter structure is tightly fitted with the sealing plate 7. At this time, the fixing block 13 is inserted into the inner cavity of the sealing plate 7, and the staff screws the fixing bolt 6 until the fixing bolt 6 is separated from the sealing plate 7. At this time, under the action of the rebound force of the spring 12, the through rod 16 is inserted into the through hole to fix the other filter structure and the sealing plate 7 in contact with it. The staff pushes the other filter structure inward, and the other filter structure drives the sealing plate 7 to move. The sealing plate 7 and the other filter structure squeeze the sealing gasket during the movement, and the excess air in the sealing airbag 8 enters the expansion strip 11, and the expansion strip 11 expands until the sealing plate 7 contacts the end of the filter slot 4 away from the opening. At this time, the fixing bolt 6 is aligned with the threaded hole 18 of the other filter structure, and the position of the mesh frame 5 is fixed by the fixing bolt 6 to fix the other filter structure. The filter mesh 9 in the other filter structure can filter the air. After the other filter structure is fixed, the staff screws another fixing bolt 6 that is compatible with the filter structure to be replaced. After the restriction on the mesh frame 5 in the filter structure is released, the staff pulls the filter structure outwards through the handle until the other sealing plate 7 connected to the filter structure can no longer move. At this time, the insertion hole 17 in the filter structure is aligned with the other fixing bolt 6, and the other fixing bolt 6 is screwed. The fixing bolt 6 is inserted into the inner cavity of the other sealing plate 7 through the insertion hole 17. The fixing bolt 6 squeezes the moving frame 14 during the insertion process, and the moving frame 14 drives the through-hole 16 away from the through-hole. When the fixing bolt 6 can no longer move, the through-hole 16 is completely separated from the through-hole, and the filter structure and the other sealing plate 7 are quickly separated. The staff pulls the filter structure outward to realize the removal of the filter structure. During the replacement of the filter structure, the dehumidifier can continue to work, and when the other sealing plate 7 approaches the opening, the excess gas in the expansion strip 11 flows back into the sealing airbag 8, and the sealing airbag 8 is used to seal the filter tank 4 to prevent dust from entering the filter tank 4.
