Description

Technical Field

[0001] The invention relates to the technical field of screening devices, in particular to a production device and a production method for a slow-release vitamin E waste liquid fertilizer. Background Art

[0002] The screening device for waste liquid fertilizer production plays a vital role in the production process. It is mainly responsible for the preliminary screening of raw materials, removing impurities and particles that do not meet production requirements, and ensuring that only raw materials that meet specific standards enter the subsequent processing links.

[0003] According to the search, the Chinese patent document, announcement number: CN 110882891 U, discloses a device for screening the quality of fertilizers after production. The present invention relates to a screening device, and in particular to a device for screening the quality of fertilizers after production. The technical problem is how to design a device for screening the quality of fertilizers after production, which can replace manual screening of fertilizers, has high work efficiency and is easy to operate. A device for screening the quality of fertilizers after production, comprises a support frame, a chassis is mounted on the support frame, the front side and the rear side of the lower part of the chassis are open, the lower hopper is mounted on one side of the chassis, which is connected to the inside of the chassis, and the support plate is mounted on the side outside the chassis close to the support frame. The present invention pours fertilizer into the lower hopper, the fertilizer falls and contacts with the screening cylinder, and the motor is started, so that the screening cylinder can be rotated to screen the fertilizer, and the transmission sheet drives the qualified fertilizer to move to the right for transportation, so that there is no need for manual screening of the fertilizer, and the work efficiency is high.

[0004] In actual application, although the above-mentioned device can effectively screen the fertilizer raw materials through the screening cylinder, the aperture of the screening holes opened on the outer wall of the screening cylinder is difficult to adjust according to the requirements of different effective processing technologies. At the same time, the fixed screening aperture also means that it is impossible to flexibly adjust according to different raw material characteristics and production process requirements, which may reduce production efficiency or increase the difficulty of subsequent processing. If the processing technology has a high level of screening, after the device screening is completed, workers are required to perform secondary screening of the fertilizer raw materials to meet the processing requirements of the waste liquid fertilizer. In view of this, we provide a production device and production method for slow-release vitamin E waste liquid fertilizer. Summary of the invention

[0007] As mentioned above, the outer wall of one end of the metal feed pipe is connected through one end of the outer wall of the first screening drum, and the outer wall of one end of the metal feed pipe is rotatably connected to one end inside the first screening drum.

[0008] As mentioned above, one end of the outer wall of the first screening drum passes through one end of the inner wall of the equipment cage, and one end of the outer wall of the first screening drum is rotatably connected to one end inside the equipment cage, the outer wall of one end of the first screening drum and one end inside the equipment cage pass through and are fixedly connected with a follower gear, and the outer wall of the follower gear is rotatably connected to one end inside the equipment cage.

[0009] As mentioned above, the output end of the first motor is fixedly connected with a driving gear, and the lower end of the outer wall of the driving gear and the lower end of the inner wall of the follower gear are meshed with each other and rotatably connected, and the driving gear is located at the bottom end inside the follower gear.

[0010] As mentioned above, the outer wall of the second screening drum is fixedly connected with multiple guide rails, and the multiple guide rails are all located inside the first screening drum. The outer wall of one end of the guide rail is connected through one end of the outer wall of the first screening drum, and one side of the outer wall of the guide rail is slidably connected with one side of the inside of the first screening drum. The outer walls of the first screening drum and the second screening drum are both provided with multiple screening holes.

[0011] As mentioned above, one end of the outer wall of the second screening drum is fixedly connected to a movable shaft, and one end of the outside of the second screening drum is rotatably connected to a movable sleeve through the movable shaft, the outer wall of one end of the movable sleeve is connected through the center of the outer wall of the movable shaft, and one end of the outer wall of the movable sleeve is rotatably connected to the inner center of the movable shaft.

[0012] As mentioned above, the outer wall of one end of the movable screw is connected through one end of the outer wall of the movable sleeve, and the outer wall of one end of the movable screw is connected through the inner center of the movable sleeve through a thread.

[0013] As mentioned above, a plurality of position limiting aids are fixedly connected to one end of the inner wall of the equipment cage, and one side of the outer wall of the position limiting aid is located on one side inside the movable sleeve.

[0015] The above, including the following steps: S1. Introduce the prepared vitamin E raw material particles into the first screening drum and the second screening drum through the metal feeding pipe to ensure that the raw materials can enter the screening system evenly and efficiently, laying a solid foundation for subsequent accurate screening; S2. Activate the second motor, whose output end drives the movable screw to rotate, and pushes the movable sleeve to move along the outer wall of the limit auxiliary device through the outer wall thread, and realizes the precise adjustment of the relative position between the first screening drum and the second screening drum, so that the particle size of the vitamin E raw material screened out by the screening hole can meet the process requirements of the production and processing of vitamin E waste liquid fertilizer; S3. Then, the first motor is activated to drive the first screening drum and the second screening drum to rotate synchronously. Under the synchronous rotation of the two drums, the vitamin E raw material particles are turned and screened between the drums to ensure that each grain of raw material can be screened evenly. At the same time, oxygen is added to the inside of the drum to meet the breathing needs of the microbial flora, promote its activity and metabolic efficiency, and avoid the microbial flora from being squeezed and causing the microbial flora to die due to lack of oxygen; S4. As the first screening drum and the second screening drum continue to rotate, the larger vitamin E raw material particles inside the drum are blocked by the staggered screening holes inside the second screening drum, while the smaller raw material particles that meet the requirements of the vitamin E waste liquid fertilizer processing technology will pass through the screening holes and be discharged from the gap at the bottom of the equipment cage. As the drums continue to rotate, the screened particles are gradually discharged from the discharge port at the bottom of the equipment cage, completing the screening process of the vitamin E raw material particles; S5.

[0016] Compared with the prior art, the production device and method of the slow-release vitamin E waste liquid fertilizer have the following beneficial effects: 1. The present invention drives the driving gear to rotate at one end of the equipment cage through the rotation of the output end of the first motor, and then drives the first screening drum and the second screening drum to rotate at the center of the equipment cage through the meshing transmission between the driving gear and the follower gear, and screens the particle size of the raw material through multiple screening holes opened on the outer walls of the first screening drum and the second screening drum to ensure that the particle size of the screened raw material meets the production standard.

[0017] 2. The present invention fixes a plurality of guide rails on the outer wall of the second screening drum, and these guide rails limit the mutual movement between the second screening drum and the first screening drum, so that the second screening drum and the first screening drum can only move horizontally along the inner wall of the first screening drum, but cannot rotate relative to each other. However, as the first screening drum rotates, the second screening drum will be driven to rotate synchronously through the action of the guide rails, ensuring that the two remain coordinated during the screening process. Furthermore, the second screening drum can be kept synchronized with the first screening drum when rotating to meet the screening requirements for raw materials for the production of vitamin E waste liquid fertilizer.

[0018] 3. The present invention activates the output end of the second motor to drive the movable screw to rotate at one end inside the equipment cage, and the outer wall thread pushes the movable sleeve to move horizontally along the outer wall of the limit auxiliary device. Under the action of the movable rotating shaft, the movable sleeve pulls the second screening drum to move horizontally along the inner wall of the first screening drum.

Activate the second motor (3), the output end of which drives the movable screw (301) to rotate, and push the movable sleeve (303) to move along the outer wall of the limit auxiliary device (304) through the outer wall thread, and realize the precise adjustment of the relative position between the first screening drum (202) and the second screening drum (203), so that the particle size of the vitamin E raw material screened out by the screening hole can meet the process requirements of the production and processing of vitamin E waste liquid fertilizer; S3. Subsequently, the first motor (205) is activated to drive the first screening drum (202) and the second screening drum (203) to rotate synchronously. Under the synchronous rotation of the two drums, the vitamin E raw material particles are turned and screened between the drums to ensure that each grain of the raw material can be screened evenly. At the same time, oxygen is added to the inside of the drum to meet the breathing needs of the microbial flora, promote its activity and metabolic efficiency, and avoid the microbial flora from being squeezed and causing the microbial flora to die due to lack of oxygen; S4. As the first screening drum (202) and the second screening drum (203) continue to rotate, the larger vitamin E raw material particles inside the drums are blocked by the staggered screening holes inside the second screening drum (203), while the smaller raw material particles that meet the requirements of the vitamin E waste liquid fertilizer processing technology will pass through the screening holes and be discharged from the bottom gap of the equipment cage (201). As the drums continue to rotate, the screened particles are gradually discharged from the discharge port at the bottom of the equipment cage (201), completing the screening process of the vitamin E raw material particles; S5. At the same time, as the drum continues to rotate, the screened particles are gradually discharged from the discharge port at the bottom of the device cage (201), and the screening success rate of the device itself is improved through continuous screening, while ensuring that the screened raw material particles have consistent quality and uniform particle size; S6. The qualified raw material particles screened out will be further dried by low-temperature drying to ensure that the nutrients in the particles are not destroyed, remove excess water in the particles, and improve the stability and insulation period of the vitamin E raw material particles.
