Description

TECHNICAL FIELD

[0001] The application relates to the technical field of agricultural production, in particular to an airflow crushing device for pesticide production. BACKGROUND

[0002] In the pesticide production process, an airflow crushing machine is used, wherein an air supply device supplies compressed air, the compressed air is sprayed into a crushing chamber at high speed through a nozzle assembly, and pesticide raw materials enter the crushing chamber through a material supply pipe, and the raw materials are repeatedly collided and rubbed at the intersection of multiple high-pressure air flows to be crushed.

[0003] When the pesticide raw materials are added into the airflow crushing machine, the raw materials may be bonded together to form blocks, so that the agglomeration phenomenon occurs, the raw materials agglomerated into blocks are difficult to be flushed apart into fine particles by the airflow at one time, and the raw materials are prone to directly fall on the bottom of the crushing chamber, so that the raw materials are not uniformly crushed, and the pesticide production quality is affected. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the utility model aims at solving the defects in the background art, and provides an airflow crushing device for pesticide production to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides an airflow crushing device for pesticide production, which comprises a crushing cylinder, a feeding valve is arranged at the top of the crushing cylinder, a material control valve is arranged at the bottom of the crushing cylinder, the output end of the material control valve is fixedly connected with a discharging pipe, a plurality of groups of airflow injection nozzles are arranged in the crushing cylinder, a circulating material pushing mechanism repeatedly hit by the airflow injection nozzles is arranged in the crushing cylinder, and a dust purification mechanism is arranged on the outer surface of the crushing cylinder.

[0006] Preferably, the circulating material pushing mechanism comprises a motor fixedly installed at the top of the crushing cylinder, and a driving shaft is fixedly connected to the output end of the motor, so that the blocky pesticide raw materials falling on the bottom of the crushing cylinder can be transported to the upper part again and be hit back and forth by the airflow injection nozzles in the falling process, so that the blocky raw materials are flushed apart into fine particles.

[0007] Preferably, a spiral blade is arranged on the outer surface of the driving shaft, and a connecting rod is fixedly connected to the inner bottom of the crushing cylinder.

[0008] Preferably, a supporting ring is fixedly connected to the end of the connecting rod away from the crushing cylinder, a pushing cylinder is fixedly connected to the top of the supporting ring, and the inner wall of the pushing cylinder is in contact with the edge of the spiral blade.

[0009] Preferably, the dust purification mechanism includes a filter frame disposed on the inner wall of the grinding cylinder, and the inside of the grinding cylinder is fixedly connected to a pipe, with the pipe connecting to the grinding cylinder at a position where the filter frame passes through.

[0010] Preferably, a blower is provided at the end of the pipe away from the crushing cylinder, and a cyclone dust collector is fixedly connected to the output end of the blower.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This airflow pulverizer for pesticide production uses a circulating feeding mechanism to continuously transport pesticide raw materials upwards and then downwards. During the downward process, the raw materials are repeatedly sprayed with airflow from multiple airflow nozzles. This repeated blowing helps to gradually break up the adhesion and improve the flowability of the raw materials, making it easier for the airflow to disperse the raw materials into fine particles and achieve a more uniform pulverization effect.

[0013] 2. This airflow pulverizer used in pesticide production can absorb the dust generated during the raw material pulverization process into the pipeline by the blower after the filter frame, and finally suck it into the cyclone dust collector. The cyclone dust collector separates and collects the dust by the force of the rotating airflow, thereby reducing the harm to the physical and mental health of the workers caused by the dust flying around.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figs. 1-3The utility model provides a kind of airflow crushing device for pesticide production, including crushing cylinder 1, the top of crushing cylinder 1 is provided with feed valve 2, the bottom of crushing cylinder 1 is provided with control valve 3, the output of control valve 3 is fixedly communicated with discharge pipe 4, the inside of crushing cylinder 1 is provided with several groups of airflow jet nozzle 5, the inside of crushing cylinder 1 is provided with the circulating push mechanism that is repeatedly hit by airflow jet nozzle 5, the outer surface of crushing cylinder 1 is provided with dust purification mechanism.

[0020] By the above technical solution, the device opens the feed valve 2 when in use and puts the pesticide raw materials into the crushing cylinder 1, and sprays the raw materials through the airflow jet nozzle 5. The raw materials are repeatedly collided and rubbed at the intersection of multiple high-pressure airflows, and the raw materials agglomerated into small pieces can be transported again to the upper part by the circulating push mechanism and then fall down, so that the airflow is repeatedly sprayed on them to break them into fine particles.

[0021] Specifically, the circulating push mechanism includes a motor 6 fixedly installed at the top of the crushing cylinder 1, and a drive shaft 7 fixedly connected to the output end of the motor 6.

[0022] By the above technical solution, the motor 6 can drive the drive shaft 7 to rotate when turned on, so that the helical blade 8 is synchronously rotated.

[0023] Specifically, the outer surface of the drive shaft 7 is provided with a helical blade 8, and the inner bottom of the crushing cylinder 1 is fixedly connected with a connecting rod 9.

[0024] By the above technical solution, the connecting rod 9 has a space with the inner wall bottom of the crushing cylinder 1, which can smoothly transport the raw materials upward during the rotation of the helical blade 8.

[0025] Specifically, the end of the connecting rod 9 away from the crushing cylinder 1 is fixedly connected with a supporting ring 10, and the top of the supporting ring 10 is fixedly connected with a push cylinder 11.

[0026] By the above technical solution, the raw materials are pushed upward in the push cylinder 11 by the helical blade 8.

[0027] Specifically, the dust purification mechanism includes a filter screen frame 12 arranged on the inner wall of the crushing cylinder 1, and a pipeline 13 fixedly communicated in the inside of the crushing cylinder 1.

[0028] By the above technical solution, the filter screen frame 12 can filter the raw material particles and let the dust in the raw materials enter the pipeline 13.

[0029] Specifically, the end of the pipeline 13 away from the crushing cylinder 1 is provided with a blower 14, and the output end of the blower 14 is fixedly connected with a cyclone dust collector 15.

[0030] By the above technical solution, the blower 14 inputs the dust into the cyclone dust collector 15, which can purify the dust and reduce the harm to human body caused by the dust floating in the air.

[0031] Working principle: In the process of airflow crushing of pesticide raw materials, the feed valve 2 is first opened to put the pesticide raw materials into the crushing cylinder 1, then the falling raw material particles are blown away by the airflow jet nozzle 5, and the raw materials will be repeatedly collided and rubbed at the intersection of multiple high-pressure airflows to be crushed. Considering that part of the raw material particles will be bonded into blocks and cause agglomeration phenomenon, which is not easy to be blown away by the airflow and directly falls on the bottom of the crushing cylinder 1, affecting the uniformity of crushing. At this time, the motor 6 can be started to drive the driving shaft 7 to rotate, and then the helical blade 8 rotates synchronously. The helical blade 8 can transport the raw materials at the bottom of the crushing cylinder 1 upwards in the rotating process, so that the raw materials are continuously transported upwards in the pushing cylinder 11 under the rotation of the helical blade 8. The raw materials are transported to the top of the pushing cylinder 11 and then fall down again, and repeatedly receive the airflow jet of multiple airflow jet nozzles 5 in the falling process. Such repeated blowing of raw materials helps to gradually break the bonding and improve the flowability of raw materials, so that the airflow can more easily blow the raw materials into fine particles to achieve more uniform crushing effect. And through the design of the circulating pushing mechanism, the raw materials can have more opportunities to contact with the airflow inside the crushing cylinder 1, reducing the formation of large blocks due to bonding of raw materials, which helps to improve the crushing efficiency. The raw materials are more likely to reach the required particle size in the process of repeated pushing and spraying. The dust generated during the crushing of raw materials can be absorbed into the pipeline 13 by the dust collector 14 after being filtered by the filter screen frame 12, and finally be sucked into the cyclone dust collector 15. The cyclone dust collector 15 separates and collects dust through the power of rotating airflow, thereby reducing the harm to the physical and mental health of workers caused by the flying dust. Finally, after completing the airflow crushing of raw materials, the control valve 3 is opened to make the raw materials discharge from the discharge pipe 4 at a suitable rate.
