Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and particularly relates to a dust pollution prevention device for the production of distiller's grains organic fertilizer. Background Art

[0002] Distiller's grains organic fertilizer is a high-quality organic fertilizer. As the main raw material of the organic fertilizer, distiller's grains are by-products from the brewing process. It contains rich organic matter, protein, amino acids, vitamins, and various trace elements, and these components play important roles in soil improvement and crop growth. During the production process, by inoculating a fermentation agent, such as a biological bacterial fertilizer fermentation agent, the decomposition and transformation of distiller's grains can be accelerated, generating a large number of beneficial microorganisms and enzymes, and further enriching the nutrient components of the fertilizer.

[0003] The preparation process of distiller's grains organic fertilizer includes the following steps: composting fermentation, piling the mixed distiller's grains into a rectangular pile with a width of about 1.52 meters and a height of about 0.81 meters for aerobic fermentation; turning the pile and after-ripening: during the fermentation process, regularly turning the pile to ensure oxygen supply and uniform fermentation. When the temperature no longer rises and drops below 45 degrees Celsius and the moisture content is below 45%, after-ripening fermentation is carried out. A turning machine is used for turning the pile. The existing turning machine does not have a dust removal function. When using the turning machine to turn the organic fertilizer, the fine raw materials and dust in the organic fertilizer will be turned out, resulting in a large amount of dust and causing environmental pollution during the operation. The prior art installs a dust collector and a dust collection box on the turning machine. The dust collector generates suction, and the generated dust is sucked into the dust collection box through a dust suction pipe for collection. However, when the organic fertilizer has a high humidity, the dust has a high humidity and is easily blocked in the dust suction pipe, resulting in a poor dust suction effect. Summary of the Invention

[0004] The present invention aims to provide a dust pollution prevention device for the production of distiller's grains organic fertilizer to solve the problem that dust with high humidity is easily blocked in the dust suction pipe.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] A dust pollution prevention device for the production of distiller's grains organic fertilizer, including an installation box fixedly arranged on a turning machine. The installation box is fixedly provided with a dust collector and a filter box. The dust collector includes a dust suction port and a dust discharge port. A dust discharge pipe is fixed between the dust discharge port and the filter box. It also includes an exhaust pipe communicated with the filter box. The installation box is fixedly provided with a motor, and the motor drives a bidirectional lead screw. The ends of the bidirectional lead screw are threadedly connected with lead screw seats. On both sides, the lead screw seats are respectively fixedly provided with half cylinders through connecting rods. After the two half cylinders are closed, they enclose the dust suction port. The inside of the half cylinder is provided with a hollow cavity. The half cylinder is provided with a plurality of through holes communicated with the hollow cavity. A sliding plate is slidably connected in the hollow cavity and slides towards the through holes. The sliding plate is fixedly provided with a top rod for closing a plurality of through holes. A spring is fixed between the sliding plate and the hollow cavity. The half cylinder is rotatably connected with a rotating shaft. One end of the rotating shaft is fixedly sleeved with a plurality of blades for cooperating with the exhaust pipe. The other end of the rotating shaft is fixedly sleeved with a push block for pushing the sliding plate to move. The thickness of the push block gradually increases along the circumferential direction.

[0007] The working principle of the present invention:

[0008] Fix the installation box at the bottom of the turning machine. The installation box moves along with the movement of the turning machine, so that the dust collector continuously sucks up the dust generated by the turning machine turning over the organic fertilizer. At this time, the two half cylinders on both sides are closed to surround the dust suction port, and the top rod closes the through holes, so as to keep the tightness between the two half cylinders. The dust collector works to generate suction force to blow the dust into the filter box through the space between the two half cylinders on both sides, the dust suction port, the dust discharge port, and the dust discharge pipe for collection. The air with a certain wind pressure after being filtered by the filter box is blown outwards through the exhaust pipe.

[0009] When the humidity of the dust is relatively high and it blocks between the two semi-cylinders on both sides, first, the bidirectional lead screw is driven to rotate by the motor. The bidirectional lead screw drives the lead screw seats on both sides to move in opposite directions. The lead screw seats drive the two semi-cylinders on both sides to move away from each other through the connecting rod. After the two semi-cylinders are separated, most of the blockages lose the limit and support of the two semi-cylinders on both sides and automatically fall downward under their own gravity. At this time, it is still necessary to clean the dust adhering to the side wall of the semi-cylinder. The lead screw is driven to continue rotating by the motor, and the semi-cylinder drives multiple blades to move to directly below the exhaust pipe. The vacuum cleaner works to make the air with a certain wind pressure blow towards the multiple blades through the exhaust pipe. The multiple blades drive the rotating shaft to rotate, and the rotating shaft drives the push block at the other end to rotate. Utilizing the characteristic that the thickness of the push block gradually increases along the circumferential direction, when the push block rotates, it pushes the sliding plate towards the through hole, causing multiple ejector rods to eject towards the inside of the semi-cylinder, destroying the dust layer adhering to each other and ejecting the dust. At this time, the spring is in a stretched state. When the thinner side of the push block rotates to abut against the sliding plate, the extrusion amplitude of the push block on the sliding plate decreases, and the spring returns to pull the sliding plate, causing the dredging rod to retract back into the hollow cavity again. Then, the above steps are repeated several times to dredge, and most of the dust adhering to the inner wall of the semi-cylinder has been cleaned at this time. Subsequently, the motor drives the bidirectional lead screw to continue rotating, making the semi-cylinder move directly below the exhaust pipe, and the high-pressure air blows downward to blow off the dust remaining on the inner wall of the semi-cylinder. Finally, the motor drives the bidirectional lead screw to rotate in the reverse direction, making the two semi-cylinders move towards each other to re-surround the dust suction port.

[0010] Advantages of the present invention

[0011] The separable semi-cylinder structure driven by a bidirectional lead screw can automatically separate the cylinder body when blocked by high-humidity materials, quickly remove large blockages using the gravity self-cleaning principle, drive the blades to rotate using the residual pressure air flow of the exhaust pipe, and drive the ejector rods to perform pulsed dredging operations through mechanical linkage. 30 - 50 ejector rod impacts can be completed in a single cleaning cycle, and efficient removal of adhering dust can be achieved without additional energy consumption; the push block-spring linkage mechanism forms a reciprocating impact mode, which can generate mechanical vibrations with an amplitude of 2 - 3 mm, effectively destroying the caked dust layer, thereby improving the cleaning effect. The whole process is automated, reducing manual intervention and improving efficiency. In addition, the device has a compact structure and is installed at the bottom of the turning machine without affecting other operations.

[0012] In some embodiments, the aperture of the through hole is 2 - 5 mm. Through a dense array distribution, the caking can be effectively broken

[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 socket joint between the semi-cylinder and the dust suction port. The sealing ring is used to improve the sealing performance.

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

[0016] In some embodiments, the exhaust pipes on both sides are located on both sides of the dust suction port. When the vacuum cleaner sucks dust, the exhaust pipes on both sides blow downward to generate a wind screen, which pushes the raised dust towards the semi-cylinder, thereby improving the dust suction efficiency.

[0025] In the following statements, the orientation words such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In practice, if the corresponding structures change in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0026] Embodiment: A dust pollution prevention device for the production of distiller's grains organic fertilizer, as Figure 1 shown, includes an installation box 1 fixedly arranged at the bottom of the turning machine 2. The turning machine 2 is provided with rollers at its bottom to enable it to move above the distiller's grains fermentation tank.

[0027] As Figure 2As shown in the figure, the installation box 1 is fixedly provided with a vacuum cleaner 7 and a filter box 3. A filter cloth is arranged in the filter box 3 to filter dust.

[0028] The vacuum cleaner 7 includes a dust suction port 11 and two dust discharge ports. A dust discharge pipe 6 is fixedly connected between the dust discharge port and the filter box 3. It also includes an exhaust pipe 8 fixedly connected to the filter box 3. The filter box 3 is symmetric about the axis of the installation box 1.

[0029] The installation box 1 is fixedly provided with a motor 4. The motor 4 drives a bidirectional lead screw 5. The end of the bidirectional lead screw 5 is threadedly connected with a lead screw seat 9. The lead screw seat 9 is horizontally slidably connected to the bottom of the installation box 1. On both sides, the lead screw seats 9 are respectively fixedly provided with half cylinders 10 through inclined connecting rods 12.

[0030] After the two half cylinders 10 are closed, the dust suction port 11 is closed; As Figure 5 shown in the figure, the inside of the half cylinder 10 is provided with a hollow cavity. The half cylinder 10 is provided with a plurality of through holes communicating with the hollow cavity. A sliding plate that slides towards the through holes is horizontally slidably connected to the hollow cavity. The sliding plate is fixedly provided with a top rod 18 that closes the plurality of through holes. A spring 14 is fixedly arranged between the sliding plate 17 and the hollow cavity. The half cylinder 10 is rotatably connected with a rotating shaft. One end of the rotating shaft is fixedly sleeved with a plurality of blades 13 that cooperate with the exhaust pipe 8. The other end of the rotating shaft is fixedly sleeved with a push block 15 that pushes the sliding plate 17 to move. The thickness of the push block 15 gradually increases along the circumferential direction.

[0031] As Figure 2 and Figure 5 shown in the figure, the installation box 1 is fixed to the bottom of the turning machine 2. The installation box 1 moves along with the movement of the turning machine 2, so that the vacuum cleaner 7 continuously sucks up the dust generated by the turning machine 2 turning over organic fertilizer. At this time, the two half cylinders 10 on both sides are closed to surround the dust suction port 11, and the top rod 18 closes the through holes, so that the space between the two half cylinders 10 is kept airtight. The vacuum cleaner 7 generates suction to blow the dust through the space between the two half cylinders 10, the dust suction port 11, the dust discharge port, and the dust discharge pipe 6 into the filter box 3 for collection. The air with a certain wind pressure after being filtered by the filter box 3 is blown outwards through the exhaust pipe 8.

[0032] As Figure 4 and Figure 6As shown in the figure, when the dust with high humidity blocks between the two semi-cylinders 10 on both sides, first, the motor 4 is driven to rotate the bidirectional lead screw 5. The bidirectional lead screw 5 drives the lead screw seats 9 on both sides to move in opposite directions. The lead screw seats 9 drive the two semi-cylinders 10 to move away from each other through the connecting rods 12. After the two semi-cylinders 10 are separated, most of the blockages lose the limitation and support of the two semi-cylinders 10 and automatically fall downward under their own gravity. At this time, it is still necessary to clean the dust adhering to the side walls of the semi-cylinders 10. The motor 4 is driven to continue rotating the lead screw, and the semi-cylinders 10 drive the multiple blades 13 to move directly below the exhaust pipe 8. The vacuum cleaner 7 works to make the air with a certain wind pressure blow through the exhaust pipe 8 towards the multiple blades 13. The multiple blades 13 drive the rotating shaft to rotate, and the rotating shaft drives the push block 15 at the other end to rotate. Utilizing the characteristic that the thickness of the push block 15 gradually increases along the circumferential direction, when the push block 15 rotates, it pushes the sliding plate 17 towards the through hole, causing the multiple ejector rods 18 to eject towards the inside of the semi-cylinder 10, destroying the mutually adhering dust layer and ejecting the dust. At this time, the spring 14 is in a stretched state. When the thinner side of the push block 15 rotates to abut against the sliding plate 17, the extrusion amplitude of the push block 15 on the sliding plate 17 decreases, and the spring 14 returns to pull the sliding plate 17, causing the dredging rod to retract back into the hollow cavity. Then, the above steps are repeated several times to dredge, and at this time, most of the dust adhering to the inner wall of the semi-cylinder 10 has been cleaned. Subsequently, the motor 4 drives the bidirectional lead screw 5 to continue rotating, causing the semi-cylinder 10 to move directly below the exhaust pipe 8, and the high-pressure air blows downward to blow off the dust remaining on the inner wall of the semi-cylinder 10. Finally, the motor 4 drives the bidirectional lead screw 5 to rotate in the reverse direction, causing the two semi-cylinders 10 to move towards each other to re-surround the dust suction port 11.
