Description

Technical Field

[0001] The invention relates to the technical field of mixing boxes, in particular to a multi-component compound fertilizer modulation and processing device and a compound fertilizer production process. Background Art

[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops.

[0003] But it also has some disadvantages. For example, its nutrient ratio needs to be proportioned during preparation so that the proportion of the prepared compound fertilizer meets the soil use requirements. Existing compound fertilizers need to be manually put into the mixing bin one by one during preparation.

[0004] However, in the prior art, when the fertilizer is stirred, a filter is usually set to perform the initial filtration of the fertilizer, which will result in insufficient stirring time for the fertilizer.

[0016] The present invention has the following beneficial effects:

[0017] (1) In the present invention, the motor is first started, and the motor drives the rotating shaft to rotate at high speed, and the rotating shaft drives the rotating sleeve to rotate at high speed, and the rotating sleeve drives the connecting shell to rotate at high speed. The centrifugal force generated when the connecting shell rotates at high speed causes the centrifugal block to slide inside the connecting shell, and the centrifugal block will approach the first annular shell, and the centrifugal block drives the rotating plate to move, which is limited by the vertical rod. During the movement of the rotating plate, the slider falls on the outer wall of the vertical rod, and the slider drives the limiting rod to fall, and the limiting rod drives the limiting shell to fall, and the limiting shell drives the third annular shell to fall, and the third annular shell drives the second annular shell to fall. At this time, the third annular shell and the second annular shell are in contact with each other. The annular shell and the first annular shell can block the annular filter, and discharge the fertilizer into the interior of the mixing box body through the feed pipe. The rotating sleeve drives the centrifugal fan to rotate. The fertilizer liquid is stirred during the rotation of the centrifugal fan, so that the fertilizer liquid can be mixed, which is convenient for subsequent separation work. At this time, the annular filter is blocked, which can accelerate the mixing speed of the fertilizer liquid and improve the mixing efficiency of the fertilizer liquid. After the mixing and stirring is completed, the rotation speed of the rotating sleeve is reduced, so that the third annular shell, the second annular shell and the first annular shell no longer block the annular filter, so that the fertilizer liquid after mixing is separated, thereby improving the production efficiency of the fertilizer liquid.

[0018] (2) According to the present invention, when the device is in high-speed rotation, the third annular shell drives the cleaning shell to fall. During the falling process, the cleaning shell contacts the annular filter screen and cleans the impurities blocked on the inner wall of the annular filter screen, thereby improving the subsequent separation efficiency of the fertilizer liquid. In addition, due to the elastic deformation of the spring, the spring causes the cleaning shell to slide under the limit of the annular groove. During the sliding process of the cleaning shell, the inner wall of the annular filter screen can be further cleaned. At the same time, the cleaning shell drives the flexible rod to move, and the flexible rod drives the sliding plate to move. At this time, the two sliding plates move away from each other, and the sliding plate drives the L-shaped rod to move. The L-shaped rod drives the moving plate to move, and the moving plate slides on the inner wall of the square shell. The sliding of the moving plate can enable the airflow inside the square shell to enter the interior of the cleaning shell through the air pipe, and the airflow is discharged outwardly through the circular hole set at the cleaning shell. During the process of the airflow being discharged outwardly, the annular filter screen attached to the outer wall of the cleaning shell will be jet-cleaned, thereby further improving the cleaning effect of the device on the annular filter screen and indirectly improving the separation efficiency of the device on the fertilizer liquid.

[0019] (3) According to the present invention, when the device is in high-speed rotation, the connecting shell drives the vertical rod to rotate, the vertical rod drives the slider to rotate, and the slider drives the semicircular frame to rotate. When the third annular shell falls, the semicircular frame will always be in a rotating state. During the rotation of the semicircular frame, it will contact one end of the extrusion rod. The semicircular block of the semicircular frame will squeeze the extrusion rod, so that the extrusion rod drives the cleaning shell to move, and the cleaning shell drives the spring to move. Under the elastic deformation of the spring, the cleaning shell can move back and forth, so that the airflow can continuously enter the interior of the cleaning shell. The airflow is sprayed toward the inner wall of the annular filter through the circular hole set at the cleaning shell, thereby improving the cleaning effect of the device on the annular filter and further improving the separation efficiency of the device for the fertilizer liquid. When the device is in high-speed rotation, the centrifugal block drives the square plate to rotate. The weight of the square plate itself can increase the weight of the centrifugal block as a whole, so that the centrifugal force is improved, and the stability of the device is improved. When the device is in low-speed rotation, the rotation of the square plate can improve the separation effect of the fertilizer liquid and further improve the separation efficiency of the fertilizer liquid.
