Technical Field
[0001] This utility model belongs to the field of organic fertilizer treatment technology, specifically, it relates to an organic fertilizer dry-wet separation device. Background Technology
[0002] Organic fertilizer dry-wet separation equipment is a key piece of equipment for processing poultry and livestock manure and converting it into organic fertilizer. It separates the solid and liquid components in the manure through mechanical force.
[0003] Existing technology discloses a dry-wet separation device for raw materials in organic fertilizer production (CN219318841U), comprising: a base, a housing mounted on the top of the base, a first motor mounted on the top of the base, and the output end of the first motor extending into the inner cavity of the housing. A gear is mounted on the output end of the first motor via a coupling. A gear ring is rotatably mounted in the inner cavity of the housing, and the gear ring meshes with the gear. A rotating drum is mounted on the inner wall of the gear ring, and the top of the rotating drum rotatably extends out of the top of the housing. The bottom of the rotating drum is rotatably mounted with the top of a fixed cylinder. In practical use, this dry-wet separation device for raw materials in organic fertilizer production allows materials to enter the equipment vertically and is dehydrated evenly and quickly using centrifugal force, preventing materials from accumulating on one side for a long time and preventing corrosion of the inner wall. It also lifts and discharges the dehydrated raw materials, enabling automatic and continuous dry-wet separation, saving labor costs and improving work efficiency.
[0004] Research revealed that existing technologies use a single centrifugal rotation method for dehydration and separation. However, this method is inefficient and ineffective when dealing with high-viscosity materials, easily resulting in the residue of fine dry materials. Furthermore, the processing of separated materials is a separate process, leading to high energy consumption and low efficiency. Moreover, existing technologies lack measures to prevent filter clogging. After the separation of high-viscosity materials or centrifugal separation, the filter is prone to frequent clogging, requiring frequent shutdowns for cleaning.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0029] An organic fertilizer dry-wet separation device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including
[0030] The outer casing 10 has a cover plate 11 installed on its top surface via a snap lock. A baffle 12 is hinged to the bottom curved surface of the outer casing 10. A control panel 13 is fixedly installed on the curved surface of the outer casing 10. A conveying rod 27 and a spiral strip 28 are rotatably provided at the bottom of the cover plate 11.
[0031] The drive structure is rotatably disposed inside the outer casing 10. The drive structure includes a water-spraying cylinder 20, a filter cylinder 19, a spiral bevel gear ring 21, a spiral bevel gear column 22, and a spiral bevel gear 34. The spiral bevel gear ring 21 is fixedly disposed on the bottom surface of the water-spraying cylinder 20, the spiral bevel gear column 22 is rotatably disposed on the bottom of the spiral bevel gear ring 21, and the spiral bevel gear 34 is driven between the spiral bevel gear ring 21 and the spiral bevel gear column 22.
[0032] The shaking structure is movably installed inside the water-spinning cylinder 20. The shaking structure includes a gear 23, an internal gear ring 24, a limiting plate 25, a movable plate 29, and a cam 32. The gear 23 is fixedly installed on the top surface of the spiral bevel gear column 22. The limiting plate 25 is installed on the bottom of the cover plate 11. The movable plate 29 is fixedly installed on the top surface of the internal gear ring 24. The cam 32 is engaged in the movable plate 29 and is fixedly installed on the bottom of the conveying rod 27. The internal gear ring 24 is driven by the gear 23 on the top surface.
[0033] like Figure 1 , Figure 2 and Figure 3As shown, the outer shell 10 has a separation chamber and a driving chamber inside. The driving chamber is set corresponding to the baffle 12. The inlet 14 and the drain valve 15 are fixedly set on the wall of the outer shell 10. The inlet 14 and the drain valve 15 are both connected to the separation chamber. The cover plate 11 is fixedly connected to the lifting cylinder 26 through a circular plate. The lifting cylinder 26 is snapped into the center of the inner side of the cover plate 11.

[0034] Specifically, the device feeds the raw material into the inner cavity of the centrifugal drum 20 through the feed inlet 14. Simultaneously, the spiral bevel gear 34 meshes with and drives the spiral bevel gear ring 21 and spiral bevel gear column 22 to rotate, driving the vibration structure to operate synchronously. At this time, the centrifugal drum 20 drives the filter cylinder 19 to rotate centrifugally, separating the material into wet and dry states. Simultaneously, the vibration structure causes the filter cylinder 19 to vibrate and shake the material. The gear 23 drives the conveying rod 27 and the spiral strip 28 to rotate, squeezing and conveying the material.

Under centrifugal force, water passes through the filter cylinder 19 and the centrifugal drum 20 and enters the space between the outer shell 10 and the centrifugal drum 20. It can be discharged by opening the drain valve 15. At the same time, the conveying rod 27 and the spiral strip 28 are driven to rotate by the drive structure, lifting the material accumulated in the inner cavity of the filter cylinder 19. The material is then lifted into the lifting cylinder 26, and finally, the dehydrated material is discharged through the discharge pipe 16, completing the wet-dry separation.

[0036] like Figure 2 and Figure 3 As shown, the spiral bevel gear column 22 and the gear 23 form a cross-section resembling an I-beam. The gear 23 is rotatably mounted on the inner bottom surface of the water-spinning cylinder 20. The spiral bevel gear ring 21 and the spiral bevel gear column 22 mesh with the same spiral bevel gear 3.

The upper half of the conveying rod 27 is a spiral rod structure, and the lower half of the conveying rod 27 is a round rod structure. The spiral strip 28 is fixedly set on the curved surface of the round rod. The conveying rod 27 passes through the cam 32 and is coaxially fixed with the gear 23.
[0038] The working principle is as follows: the control panel 13 drives the motor 17, the motor 17 drives the spiral bevel gear 34, the spiral bevel gear 34 meshes with the spiral bevel gear ring 21 and the spiral bevel gear column 22 to rotate, the spiral bevel gear ring 21 and the spiral bevel gear column 22 drive their respective corresponding water-throwing cylinders 20 and gears 23 to rotate in opposite directions, the water-throwing cylinder 20 achieves centrifugal rotation, the gear 23 drives the conveying rod 27 and the cam 32 to rotate, the conveying rod 27 and the spiral strip 28 lift the dry material in the lifting cylinder 26, and the gear 23 engages eccentrically with the internal gear ring 24.
[0039] like Figure 4 As shown, the top surface of the movable plate 29 is provided with a magnetic suction groove 31, and the bottom surface of the filter cylinder 19 is provided with a magnetic suction ring 33. The magnetic suction groove 31 and the magnetic suction ring 33 are magnetically connected. The cam 32 is eccentrically set with the conveying rod 27. An eccentric hole is opened in the movable plate 29. The cam 32 is engaged in the eccentric hole. The filter cylinder 19 is sleeved on the outside of the conveying rod 27 and the spiral strip 28.
[0040] like Figure 3 , Figure 4 and Figure 5 As shown, the inner side of the water-spinning cylinder 20 is filled with filter element 18, and two movable shafts 30 are symmetrically fixed on the top surface of the movable plate 29. The bottom surface of the limiting plate 25 is symmetrically provided with two circular grooves with a diameter larger than that of the movable shafts 30. The movable shafts 30 rotate eccentrically in the circular grooves.
[0041] The working principle is as follows: the magnetic connection between the magnetic suction groove 31 and the magnetic suction ring 33 facilitates the quick installation between the filter cartridge 19 and the movable plate 29, allowing the device to be adapted according to the dryness and particle size of the material. The eccentric rotation of the cam 32 drives the eccentric rotation of the movable plate 29 and the internal toothed ring 24. At this time, the two moving shafts 30 above the movable plate 29 rotate eccentrically in the corresponding circular grooves. The circular grooves limit the movement direction of the moving shafts 30. The eccentrically rotating filter cartridge 19 and the centrifugally rotating water-spinning cylinder 20 cooperate to achieve a shaking and circling effect, thereby avoiding the accumulation and blockage of material in the filter cartridge 19 to a certain extent, thus reducing the number of times the machine needs to be stopped for cleaning.
