Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to a dust pollution prevention device for the production of organic fertilizer from distiller's grains. Background Technology

[0002] Distillers' grains organic fertilizer is a high-quality organic fertilizer. As a primary raw material for organic fertilizer, distillers' grains are a byproduct of the brewing process. It is rich in organic matter, protein, amino acids, vitamins, and various trace elements, all of which play a vital role in soil improvement and crop growth. During the production process, inoculating the grains with a fermentation agent, such as a bio-fertilizer fermentation agent, accelerates the decomposition and transformation of the grains, generating a large number of beneficial microorganisms and enzymes, further enriching the fertilizer's nutritional composition.

[0003] The preparation process of organic fertilizer from distiller's grains includes the following steps: composting fermentation; the mixed distiller's grains are piled into a rectangular heap approximately 1.52 meters wide and 0.81 meters high for aerobic fermentation; turning and post-fermentation: during fermentation, the heap is turned regularly to ensure oxygen supply and uniform fermentation. Post-fermentation is carried out when the temperature stops rising and drops below 45 degrees Celsius and the moisture content is below 45%. A compost turner is used for turning. Existing compost turners do not have dust removal capabilities. When turning the organic fertilizer, fine raw materials and dust are thrown out, resulting in a large amount of dust and causing environmental pollution. Current technology uses a vacuum cleaner and dust collection box installed on the compost turner. The vacuum cleaner generates suction, drawing the dust into the dust collection box for collection. However, when the organic fertilizer has high moisture content, the dust is prone to clogging the suction pipe, resulting in poor dust collection efficiency. Summary of the Invention

[0004] The present invention aims to provide a dust pollution prevention device for the production of organic fertilizer from distiller's grains, in order to solve the problem that high dust moisture content easily causes blockage in the dust suction pipe.

[0005] To address the above problems, the present invention provides the following technical solution:

[0006] A dust pollution prevention device for producing organic fertilizer from distiller's grains includes a mounting box fixedly mounted on a turning machine. The mounting box is fixedly equipped with a vacuum cleaner and a filter box. The vacuum cleaner includes a suction port and a discharge port, and a dust discharge pipe is fixed between the discharge port and the filter box. It also includes an exhaust pipe connected to the filter box. The mounting box is fixedly equipped with a motor that drives a bidirectional lead screw. The end of the bidirectional lead screw is threadedly connected to a lead screw seat. Half-cylinders are fixedly mounted on both sides of the lead screw seat via connecting rods. When the two half-cylinders are closed, they seal the suction port. The interior of the semi-cylinder is provided with a hollow cavity. The semi-cylinder has multiple unblocking holes communicating with the hollow cavity. The hollow cavity is slidably connected to a sliding plate that is slidably connected to the unblocking holes. The sliding plate is fixedly provided with a top rod that closes the multiple unblocking holes. A spring is fixedly provided between the sliding plate and the hollow cavity. The semi-cylinder is rotatably connected to a rotating shaft. One end of the rotating shaft is fixedly sleeved with multiple blades that cooperate with the exhaust pipe. The other end of the rotating shaft is fixedly sleeved with a push block that pushes the sliding plate to move. The thickness of the push block gradually increases along the circumferential direction.

[0007] Working principle of the invention:

[0008] The mounting box is fixed to the bottom of the compost turner. The mounting box moves with the compost turner, causing the vacuum cleaner to continuously suck up the dust generated by the compost turner turning the organic fertilizer. At this time, the two half-cylinders close together and surround the dust inlet. The top rod seals the drainage hole, keeping the two half-cylinders airtight. The vacuum cleaner generates suction to blow the dust through the space between the two half-cylinders, the dust inlet, the dust outlet, and the dust outlet pipe into the filter box for collection. After being filtered by the filter box, the air with a certain wind pressure is blown out through the exhaust pipe.

[0009] When the dust, due to its high moisture content, clogs the space between the two half-cylinders, the motor first drives the bidirectional lead screw to rotate. This drive causes the lead screw seats on both sides to move in opposite directions. The lead screw seats, via connecting rods, cause the two half-cylinders to separate. Once separated, most of the blockage, no longer restrained or supported by the two half-cylinders, falls downwards under its own weight. At this point, the dust adhering to the side walls of the half-cylinders needs to be cleaned. The motor then drives the lead screw to continue rotating, moving the half-cylinders and multiple blades directly below the exhaust pipe. The vacuum cleaner's operation then causes air with a certain pressure to be blown through the exhaust pipe towards the multiple blades. Each blade drives a rotating shaft, which in turn drives a pusher block at the other end. Utilizing the pusher block's gradually increasing thickness along its circumference, its rotation pushes a sliding plate towards the unclogging hole, causing multiple push rods to push outwards towards the interior of the half-cylinder. This breaks down the adhered dust layer and dislodges the dust. At this point, the spring is stretched. When the thinner side of the pusher block rotates to contact the sliding plate, the pressure exerted by the pusher block on the sliding plate decreases, and the spring returns, pulling the sliding plate back into the hollow cavity. This process is repeated several times, removing most of the dust adhering to the inner wall of the half-cylinder. The motor then drives a bidirectional screw to continue rotating, moving the half-cylinder directly below the exhaust pipe. High-pressure air blows away any remaining dust on the inner wall of the half-cylinder. Finally, the motor drives the bidirectional screw to rotate in the opposite direction, causing the two half-cylinders to move towards each other and re-encircle the suction port.

[0010] Beneficial effects of the present invention

[0011] The bidirectional screw-driven, detachable semi-cylinder structure automatically separates the cylinder when encountering blockages caused by high-humidity materials. Utilizing gravity self-cleaning, it quickly removes large blockages. Residual air pressure from the exhaust pipe drives the blades to rotate, and mechanical linkage drives the push rod for pulse-type unblocking. A single cleaning cycle can complete 30-50 push rod impacts, achieving highly efficient removal of attached dust without additional energy consumption. The push block-spring linkage mechanism creates a reciprocating impact mode, generating mechanical vibrations with an amplitude of 2-3mm, effectively breaking down the caked dust layer and improving cleaning efficiency. The entire process is automated, reducing manual intervention and increasing efficiency. Furthermore, the device has a compact structure and is installed at the bottom of the turner, without interfering with other operations.

[0012] In some embodiments, the diameter of the unblocking holes is 2–5 mm. Through a dense array distribution, the ability to break up compaction can be effectively improved.

[0013] In some embodiments, the cross-sectional shape of the sliding plate is arc-shaped.

[0014] In some embodiments, a sealing ring is installed at the joint between the half-tube and the suction port. The sealing ring improves the sealing performance.

[0015] In some embodiments, the plurality of dredging holes are arranged at uniform intervals along the vertical direction.

[0016] In some embodiments, the exhaust pipes on both sides are located on either side of the suction port. When the vacuum cleaner is vacuuming, the exhaust pipes on both sides blow air downwards, creating an air screen that pushes the dust into the half-tube, thereby improving vacuuming efficiency.

[0025] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0026] Example: A dust pollution prevention device for the production of organic fertilizer from distiller's grains, such as... Figure 1 As shown, it includes a mounting box 1 fixedly installed at the bottom of the turner 2, and the turner 2 moves above the fermentation tank of lees by installing rollers at its bottom.

[0027] like Figure 2As shown, the mounting box 1 is fixedly equipped with a vacuum cleaner 7 and a filter box 3. The filter box 3 is equipped with a filter cloth to filter dust.

[0028] The vacuum cleaner 7 includes a suction port 11 and two exhaust ports. The exhaust ports and the filter box 3 are fixedly connected by an exhaust pipe 6. It also includes an exhaust pipe 8 fixedly connected to the filter box 3. The filter box 3 is symmetrical along the axis of the mounting box 1.

[0029] The mounting box 1 is fixedly equipped with a motor 4, which drives a bidirectional lead screw 5. The end of the bidirectional lead screw 5 is threadedly connected to a lead screw seat 9, which is horizontally slidably connected to the bottom of the mounting box 1. Half-cylinders 10 are fixedly mounted on both sides of the lead screw seats 9 via inclined connecting rods 12.

[0030] When the two half-cylinders 10 are closed, the suction port 11 is sealed; Figure 5 As shown, the interior of the half-cylinder 10 is provided with a hollow cavity. The half-cylinder 10 is provided with multiple drainage holes communicating with the hollow cavity. A sliding plate is slidably connected to the hollow cavity and slidably connected to the drainage holes. A top rod 18 is fixedly provided on the sliding plate to close the multiple drainage holes. A spring 14 is fixedly provided between the sliding plate 17 and the hollow cavity. The half-cylinder 10 is rotatably connected to a rotating shaft. Multiple blades 13 that cooperate with the exhaust pipe 8 are fixedly sleeved at one end of the rotating shaft. A push block 15 that pushes the sliding plate 17 to move is fixedly sleeved at the other end of the rotating shaft. The thickness of the push block 15 gradually increases along the circumferential direction.

[0031] like Figure 2 and Figure 5 As shown, the mounting box 1 is fixed to the bottom of the compost turner 2. The mounting box 1 moves with the compost turner 2, so that the vacuum cleaner 7 continuously sucks up the dust generated by the compost turner 2 turning the organic fertilizer. At this time, the two half cylinders 10 close together and surround the dust inlet 11. The top rod 18 closes the drainage hole, so that the two half cylinders 10 are sealed. The vacuum cleaner 7 generates suction to blow the dust through the space between the two half cylinders 10, the dust inlet 11, the dust outlet, and the dust outlet pipe 6 into the filter box 3 for collection. After being filtered by the filter box 3, the air with a certain wind pressure is blown out through the exhaust pipe 8.

[0032] like Figure 4 and Figure 6As shown, when the dust has a high humidity level and clogs the space between the two half-cylinders 10, the motor 4 first drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 drives the lead screw seats 9 on both sides to move in opposite directions. The lead screw seats 9, through the connecting rod 12, cause the two half-cylinders 10 to move apart. After the two half-cylinders 10 separate, most of the blockage loses the limitation and support of the two half-cylinders 10 and falls down automatically under its own weight. At this time, it is still necessary to clean the dust adhering to the side wall of the half-cylinder 10. The motor 4 drives the lead screw to continue rotating, and the half-cylinder 10 moves multiple blades 13 to directly below the exhaust pipe 8. The vacuum cleaner 7 works so that air with a certain wind pressure is blown through the exhaust pipe 8 towards the multiple blades 13. Each blade 13 drives the rotating shaft to rotate, which in turn drives the pusher block 15 at the other end to rotate. Utilizing the characteristic that the thickness of the pusher block 15 gradually increases along the circumference, as the pusher block 15 rotates, it pushes the sliding plate 17 towards the unblocking hole, causing multiple push rods 18 to push outwards towards the interior of the semi-cylinder 10, breaking down the adhering dust layer and dislodging the dust. At this time, the spring 14 is in a stretched state. When the thinner side of the pusher block 15 rotates to abut against the sliding plate 17, the pressure exerted by the pusher block 15 on the sliding plate 17 decreases, and the spring 14 returns to its original position, pulling the sliding plate 17 back into the hollow cavity. This process is repeated several times to remove most of the dust adhering to the inner wall of the semi-cylinder 10. Subsequently, the motor 4 drives the bidirectional lead screw 5 to continue rotating, moving the semi-cylinder 10 directly below the exhaust pipe 8. High-pressure air blows down to remove the remaining dust from the inner wall of the semi-cylinder 10. Finally, the motor 4 drives the bidirectional lead screw 5 to rotate in the opposite direction, causing the two half-cylinders 10 to move towards each other and re-encircle the suction port 11.
