Description

TECHNICAL FIELD

[0001] The present application relates to the field of fertilizer processing and production, and particularly relates to a crushing device for fertilizer production. BACKGROUND

[0002] In the application No. CN202410615075.4, a crushing device for compound fertilizer production is provided to solve the problem of crushing effect. The device specifically comprises a housing, a quantitative feeding part arranged above the housing, and a feeding hopper arranged above the quantitative feeding part. The inside of the housing is connected with a crushing part through a crushing shaft, and the bottom inner wall of the housing is fixed with a screen. The device uses the continuous cooperation of the outer convex crushing disc and the inner concave cooperation ring to separate and crush the materials. In this way, the static pressure during cooperation can be used to crush the materials, and the outer convex crushing disc can also rotate at high speed to achieve a "rubbing" grinding effect with the static inner concave cooperation ring, thereby increasing the final crushing effect and the degree of crushing precision. In addition, the materials are rubbed along the vertical plane in a vortex line path from top to bottom, which increases the crushing path and further improves the grinding effect.

[0003] The prior art of the above-mentioned patent includes that when the crushing cylinder in the device is blocked, the operator often has to stop the operation of the entire device due to the limitations of the overall structure and operation mechanism, because the components in the device are highly correlated and cannot be independently processed in case of failure of a single crushing cylinder. The overall shutdown not only forces the grinding and crushing work in progress to be interrupted, but also requires the entire production chain to be temporarily suspended, which seriously damages the continuity of production and wastes a large amount of time in restarting preparation, troubleshooting, and blockage cleaning. Frequent starting and stopping of the device also consumes additional energy, increases production costs, and directly leads to loss of production capacity, making it difficult to achieve the expected target of fertilizer production and unable to meet market demand.

[0057] Working principle:

[0058] First, the raw materials are poured into the feeding port, at this time, the driving assembly 2 is started, the power output shaft of the driving assembly 2 drives a plurality of telescopic assemblies 5 to rotate at the same time, and a plurality of crushing cylinders 3 connected with the telescopic assemblies 5 are driven to rotate in the grinding groove, so that a plurality of groups of raw materials can be ground at the same time, the grinding efficiency is high, and if any one of the crushing cylinders 3 is blocked during the process, the material is grouped by cooperating with the partition plate 93, and the raw material will accumulate on the discharge disc 91 at the top of the crushing cylinder 3, at this time, the personnel can judge the blocking state of any one of the crushing cylinders 3 according to the accumulation state;

[0059] The solution to the blockage is as follows: start the electric telescopic rod 8 of one of the groups, push the extension rod 72, the dispersion strip 71 and the spikes 73 upward by the electric telescopic rod 8, synchronously lift the rotating rod 43 and the grinding roller 41 upward, at this time, the blockage stuck between the grinding roller 41 and the bottom of the grinding groove will directly fall onto the sieve disc 6, since the sieve disc 6 can filter large-particle blockage, the blockage will be blocked by the sieve disc 6 and cannot pass through, at this time, the rotation of the rotating rod 43 will drive the scraping rod 44 and the conical scraper at the bottom of the scraping rod 44 to push the blockage on the sieve disc 6, when the blockage is pushed to the inner discharge port 02, it can be discharged through the inner discharge port 02 and discharged through the outer discharge port 01 at the bottom of the equipment frame 1; in the process, the scraping rod 44 can also improve the filtering efficiency when scraping the material, avoiding the accumulation of the material during filtering;

[0060] It should be noted that when the grinding roller 41 moves upward, the process of discharging the blockage will block the material at the top, and the rotation can simultaneously grind the material, and the structure cooperates with the rotation of the material guide rod 42 to realize the dredging of the discharging position, thereby reducing the degree of blockage of the equipment and avoiding the accumulation of the material during discharging;

[0061] Secondly, when the electric telescopic rod 8 pushes the linkage assembly 7 to rise, the top of the linkage assembly 7 contacts the bottom of the sieve disc 6, pushing the sieve disc 6 upward, at the same time, the top ends of the multiple spikes 73 on the dispersion strip 71 will penetrate the mesh holes of the sieve disc 6, in the process, the material blocked in the mesh holes will be cleaned, improving the filtering effect of the sieve disc 6, avoiding the problem of manually disassembling the equipment to clean the sieve disc 6, and improving the production efficiency of the equipment;

[0062] The qualified crushed material after filtering is discharged through the bottom discharge port of the equipment frame 1; personnel can observe that any one of the crushing cylinders 3 is blocked, or can remotely observe through the assembly of a camera device, and the telescopic rod 8 is controlled remotely to dredge the accumulated material at the top of the single blocked crushing cylinder 3, which can improve the production efficiency while reducing the labor intensity of personnel maintaining the equipment, thereby improving the production efficiency;

[0063] Compared with the traditional equipment, when one of the crushing cylinders 3 is blocked, only the blocked part needs to be dredged, and the other crushing cylinders 3 and the crushing assembly 4 can still work normally and will not be affected, without the need for shutdown operation and wasting time.

[0064] Certain exemplary embodiments of the application have been described herein in an illustrative fashion, and it is to be understood that various modifications to the embodiments described herein can be made by one skilled in the art without departing from the spirit and scope of the application, as described by the following claims.
