Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer filtration, in particular to a filtering device for fertilizer production. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, and multi-dimensional field energy concentrated organic fertilizers. Fertilizers are compounds that help plants grow.

[0003] In agricultural fertilizer production, a filtering and screening device is required to screen the fertilizer. However, the structure of the commonly used filtering and screening devices in the prior art is too simple and lacks corresponding auxiliary components. The material in the hopper often gets clogged during the falling process, requiring frequent manual intervention, observation, and treatment. In order to reduce the manual intervention rate, it is necessary to enrich the structure of the filtering and screening device and thus improve its functionality. Therefore, a filtering device for fertilizer production is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a filtering device for fertilizer production.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A filtering device for fertilizer production comprises a box body, the box body is provided with multiple openings, two filter screens are provided inside the box body, a hopper is provided above the box body, a collecting trough is provided on the side wall of the box body through a support frame, a circulation trough is provided at the bottom of the box body, a reciprocating screw is provided on the upper end surface of the box body through two first support plates, a sliding rod is provided on the upper end surface of the box body through two second support plates, a transmission shaft is provided on the upper end surface of the box body, a movable plate is provided on the hopper through a movable opening, the movable plate is threadedly sleeved on the reciprocating screw through a limiting mechanism, the reciprocating screw is connected to the transmission shaft through a transmission mechanism, an impact frame is provided on the slide rod through an elastic mechanism sliding sleeve, and the transmission shaft is connected to the impact frame through a meshing mechanism.

[0013] Beneficial effects of the utility model:

[0014] 1. A movable plate is set at the hopper, and the reciprocating screw is driven by the driving motor to rotate, so that the movable plate moves back and forth in the movable opening, controlling the intermittent entry of the material in the hopper into the box body to avoid blockage caused by excessive feeding at one time.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-3 A filtering device for fertilizer production includes a box body 1, a plurality of openings 22 are provided on the box body 1, two filter screens 2 are provided inside the box body 1, and a discharge plate 4 corresponding to the opening 22 is also provided on the inner wall of the box body 1. The discharge plate 4 is also inclined and corresponds to the collection tank 6.

[0025] A hopper 3 is provided above the box body 1, a collecting trough 6 is provided on the side wall of the box body 1 through a support frame 5, a circulation groove 7 is provided at the bottom of the box body 1, a reciprocating screw 12 is provided on the upper end surface of the box body 1 through two first support plates 11, a slide rod 17 is provided on the upper end surface of the box body 1 through two second support plates 16, a transmission shaft 14 is provided on the upper end surface of the box body 1, a movable plate 10 is provided on the hopper 3 through a movable opening 9, the movable plate 10 is threadedly sleeved on the reciprocating screw 12 through a limiting mechanism, the reciprocating screw 12 is connected to the transmission shaft 14 through a transmission mechanism, an impact frame 18 is provided on the slide rod 17 through an elastic mechanism sliding sleeve, and the transmission shaft 14 is connected to the impact frame 18 through an engagement mechanism.

[0026] The limiting mechanism includes a limiting rod 13 mounted between the two first support plates 11. The limiting rod 13 is parallel to the reciprocating screw 12 and slides through the movable plate 10. The limiting rod 13 limits the movable plate 10, preventing it from rotating with the reciprocating screw 12. A drive motor connected to the reciprocating screw 12 is also provided on the first support plate 11 near the hopper 3 to provide power.

[0027] The transmission mechanism includes two meshing transmission gears 15 mounted on the reciprocating screw 12 and the transmission shaft 14. The transmission gears 15 are bevel gears. These transmission gears 15 transmit power from the drive motor to the transmission shaft 14.

[0028] The elastic mechanism includes a spring 19 mounted on the outside of the slide bar 17. The two ends of the spring 19 are elastically connected to the outer wall of the second support plate 16 and the outer wall of the impact frame 18. The elastic potential energy provided by the spring 19 can drive the impact frame 18 to move back to its original position and impact the hopper 3 after it moves a certain distance and no external force is applied.

[0029] The meshing mechanism includes a meshing gear 20 mounted on the transmission shaft 14, and a rack 21 is provided on the impact frame 18 to cooperate with the meshing gear 20. The meshing gear 20 is an incomplete gear. Only when the meshing gear 20 is an incomplete gear will it lose meshing with the rack 21.

[0030] Both filters 2 are set at an angle, and the mesh size of the two filters 2 increases from top to bottom. The inclined setting of the filter 2 allows the filtered fertilizer to slide smoothly along the filter 2, avoiding accumulation on the filter 2 and affecting the filtration efficiency. Since the mesh size increases from top to bottom, larger particles of fertilizer will be intercepted by the upper filter 2, and smaller particles of fertilizer can pass through the upper filter 2 into the lower filter 2 for further filtration. Finally, it enters the circulation tank 7, and is either filtered again or taken out directly for use. A guide plate 8 is also provided on the inner wall of the box body 1 to ensure that the material can smoothly enter the circulation tank 7 for collection to avoid accumulation in one place.

[0031] When the utility model is used, the material is stored in the hopper 3. When the filtering operation is performed, the driving motor is started to drive the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, the movable plate 10 moves back and forth in the movable port 9, so that the material in the hopper 3 indirectly enters the box body 1, is filtered and classified through the upper and lower filter screens 2, and finally enters the circulation tank 7 for collection. At this time, you can choose to filter it again for circulation, or directly take it out for collection or use.

[0032] When the reciprocating screw 12 rotates, the transmission shaft 14 can be driven to rotate with the help of the transmission gear 15. The rotation of the transmission shaft 14 can drive the impact frame 18 to move and the raw material hopper 3 with the help of the meshing gear 20 and the rack 21. When the meshing gear 20 and the rack 21 lose engagement, the elastic potential energy provided by the spring 19 can make the impact frame 18 move and reset, and hit the hopper 3. The impact generates vibration, which can avoid blockage of the vertical part of the hopper 3 and affect the discharge.

[0033] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
