[0001] This utility model relates to the field of organic fertilizer manufacturing technology, specifically to a screening device for organic fertilizer production. Background Technology

[0002] The raw materials for organic fertilizer production are mainly carbon-containing materials such as plants or animals. The production process generally includes fermentation, granulation, drying, and screening. In order to improve production efficiency, manufacturers now usually use integrated production equipment for organic fertilizer production.

[0003] The crushing and granulation device for producing organic fertilizer disclosed in CN114570486B has a movable filter frame set on a fixed base. The granulation frame is located above the filter frame. The formed fertilizer granules fall from the bottom and are shaped and pre-dried by a triangular air blower. Finally, they fall into the filter frame. The filter frame is reciprocated under the support of a ball bearing controlled by a vibration motor to screen out the crushed granules and leave qualified granules in the filter frame.

[0004] The debris sieved out by the filter frame falls directly onto the fixed base, requiring manual cleaning. Furthermore, the support frame on the fixed base that supports the mixing tank also obstructs the cleaning of the countertop, making it quite difficult to clean.

[0005] In view of the problems existing in the prior art, this utility model designs and manufactures a screening device for organic fertilizer production to overcome the above defects. Utility Model Content

[0006] In response to the problems existing in the prior art, this utility model provides a screening device for organic fertilizer production that can separate qualified particles from debris and achieve self-cleaning of the work surface.

A perforated plate is installed on the upper end of the storage chamber. The upper end of the inclined plate is fixed to the frame, and the lower end of the inclined plate abuts against one end of the perforated plate. A partition is installed inside the storage chamber, which divides the storage chamber into a debris area and a qualified area. The qualified area is located on the side of the partition closer to the inclined plate.

[0009] The screening table is equipped with a driving device, which can drive the screening frame to move back and forth above the debris area to screen the particles. After screening, the driving device can drive the screening frame to move to the inclined plate.

[0010] One end of the screening frame is equipped with a discharge gate. The upper end of the discharge gate is hinged to the screening frame, and the lower end of the discharge gate can abut against the inner wall of the lower end of the screening frame.

[0017] Preferably, a sliding plate is installed at the lower end of the granulator, and a blower capable of blowing air onto the sliding plate is installed on the frame.

[0018] Preferably, a buffer block is installed on the inner wall of the screening frame so that particles falling from the lower end of the sliding plate can be cushioned by landing on the buffer block.

[0019] Preferably, the upper end face of the storage cavity is provided with a limiting slope, and the edge of the hollow plate is provided with an inclined edge that cooperates with the limiting slope, and the limiting slope can restrict the displacement of the hollow plate.

[0020] Preferably, the upper surface of the partition plate abuts against the lower surface of the perforated plate.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model sets up a storage chamber and an inclined plate in two zones on the screening table, and controls the screen frame to move on the perforated plate and the inclined plate through the drive device.

Detailed Implementation

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-3The screening device shown includes a granulator 3 and a screening table 9. The screening table 9 is equipped with a frame 5. The granulator 3 is fixed on the upper end of the frame 5. A screening frame 16 that can move to the bottom of the granulator 3 to receive material is placed on the screening table 9. A sliding plate 17 is installed at the lower end of the granulator 3. A blower 1 that can blow air onto the sliding plate 17 is installed on the frame 5. A buffer block 14 is installed on the inner wall of the screening frame 16 so that the particles falling from the lower end of the sliding plate 17 can fall on the buffer block 14 for cushioning.

[0031] Specifically, the granules produced by granulator 3 fall from the sliding plate 17. During the falling process, the gas blown by blower 1 makes the granules drier and less prone to breakage. At the same time, the buffer block 14 on the screen frame 16 also buffers the falling granules, preventing them from breaking during collection.

[0032] One end of the screening table 9 of this utility model is provided with a storage cavity 10, and the other end of the screening table 9 is equipped with an inclined plate 4. A hollow plate 15 is installed on the upper end of the storage cavity 10. The upper end of the inclined plate 4 is fixed on the frame 5, and the lower end of the inclined plate 4 abuts against one end of the hollow plate 15.

[0033] The screening table 9 of this utility model is equipped with a drive device that controls the reciprocating movement of the screening frame 16 on the hollow plate 15 and the inclined plate 4. The drive device includes a lead screw 7, which is installed on one side of the screening frame 16. A slide 22 is installed on the lead screw 7 and is rotatably connected to the screening frame 16. A motor 6 is installed on the screening table 9 and is connected to one end of the lead screw 7. The rotation of the motor 6 drives the screening frame 16 to move along the lead screw 7. When it encounters the inclined plate 4, the screening frame 16 can rotate relative to the slide 22, and it can climb the slope under the drive of the motor 6.

[0034] The upper end face of the storage cavity 10 of this utility model is provided with a limiting slope 18, and the edge of the hollow plate 15 is provided with an inclined edge 8 that cooperates with the limiting slope 18. The limiting slope 18 can restrict the displacement of the hollow plate 15. The hollow plate 15 is placed directly on the inclined edge 8, and will not shake or fall into the storage cavity 10. A partition 12 is installed inside the storage cavity 10. The upper end face of the partition 12 abuts against the lower end face of the hollow plate 15, and plays a role in supporting the hollow plate 15.

[0035] Specifically, the partition 12 divides the storage chamber 10 into a debris zone 13 and a qualified zone 11. The qualified zone 11 is located on the side of the partition 12 near the inclined plate 4. After the material is received, the motor 6 starts and repeatedly reverses to control the screen frame 16 to move back and forth above the debris zone 13 to screen the particles. The debris that is screened can fall directly into the debris zone 13.

[0036] The present invention provides a discharge gate 2 at one end of the screening frame 16. The upper end of the discharge gate 2 is hinged to the screening frame 16, and the lower end of the discharge gate 2 can abut against the inner wall of the lower end of the screening frame 16. The surfaces of the discharge gate 2 and the screening frame 16 that are in contact with each other are provided with magnets that can attract each other.

[0037] Specifically, when the screening frame 16 can move onto the inclined plate 4, the attractive force of the two magnets is less than the total weight of the particles in the discharge gate 2 and the screening frame 16. The two magnets separate, and the discharge gate 2 rotates to a state perpendicular to the ground, thus opening the discharge gate 2. Under the joint guidance of the discharge gate 2 and the limiting slope 18, all the screened particles are poured into the qualified area 11.

[0038] It enables the separation of debris and whole particles, improving production quality, and allows for separate storage of both for convenient subsequent processing. It also facilitates the collection and recycling of debris, reducing production costs.

[0039] A brush 19 is installed at the lower end of the screening frame 16 of this utility model. The brush 19 is located at the end of the screening frame 16 near the unloading gate 2. The lower end of the brush 19 can contact the perforated plate 15. After the particles in the screening frame 16 are screened, during the process of the motor 6 controlling the screening frame 16 to move towards the inclined plate 4, the brush 19 can sweep the particles on the perforated plate 15 into the storage chamber 10, realizing the self-cleaning of the screening table 9 and keeping the working environment clean at all times.

[0040] The screen frame 16 of this utility model is equipped with a first rotating roller 21 and a second rotating roller 20. When they roll, they will not get stuck in the holes of the perforated plate 15, and can raise the screen frame 16 to avoid contact with the perforated plate 15, reduce friction and extend the service life of the perforated plate 15 and the screen frame 16.

[0041] Specifically, the first rotating roller 21 is installed at the end of the screen frame 16 away from the unloading gate 2. When the screen frame 16 moves towards the inclined plate 4, the first rotating roller 21 is located at the front of the screen frame 16, so that when the screen frame 16 moves to the lower end of the inclined plate 4, it can smoothly rotate around the hinge of the slide seat 22 and climb upward, avoiding the situation where the end of the screen frame 16 hits the inclined plate 4 and the screen frame 16 cannot move forward.

[0042] The second rotating roller 20 of this utility model is installed on the lower end face of the screen frame 16 near the discharge gate 2. The lower end faces of the first rotating roller 21 and the second rotating roller 20 are at the same height. Before the screen frame 16 moves to the inclined plate 4, the screen frame 16 can maintain a state parallel to the upper end face of the screening table 9 to avoid tilting. Under the weight of the discharge gate 2 and the impact of the particles, the two magnets are separated and opened, and the particles leak from the end of the screen frame 16.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
