Description

Technical Field

[0001] The invention relates to the technical field of suspension production, in particular to a grinding device for producing pesticide suspension. Background Art

[0002] Pesticide suspension concentrate is a high suspension rate, flowable solid-liquid system made by mixing water-insoluble solid pesticide original with surfactants (such as wetting agents, dispersants, etc.) and other additives through grinding, dispersion and other processes.

[0003] The grinding process of suspension concentrate is a very critical link in the production process. Its purpose is to refine the solid pesticide technical particles and evenly disperse them in the suspension system, thereby improving the performance and quality of the suspension concentrate.

[0004] In the prior art, the grinding process of suspensions usually requires preliminary crushing and then fine grinding. The larger original drug particles are crushed by crushing equipment to reduce the particle size range, creating conditions for fine grinding, and then the particles are further refined by grinding equipment to make the particle size meet the requirements of suspensions. However, this operation method requires separate operations by equipment responsible for crushing and grinding. Crushing and grinding require different equipment, which increases equipment investment and floor space.

[0005] After the batches of technical particles are crushed, the staff needs to feed the crushed suspension into the grinding equipment. The step-by-step operation requires manual material transfer, which increases the labor intensity and operation complexity. During the crushing process, the raw materials are prone to splashing everywhere, which not only causes material waste, but also may cause dust pollution and affect the health of operators.

[0026] Working principle: In this embodiment, the present invention also proposes a method for using a grinding device for producing a pesticide suspension, comprising the following steps: Step 1: First, connect the electrical equipment with the wire and power it on. Then, adjust the position of the connecting block 17 in the grinding box 2 according to the rear end of the suspension after grinding. Start the electric push rod 32 to lift the grinding assembly as a whole, and then control the position of the connecting block 17 in the grinding box 2, so as to control the distance between the connecting block 17 and the grinding box 2. Then, inflate the airbag 23 to make sure there is no gap between the guide box 21 and the connecting block 17 to prevent leakage of the ground suspension. Then, take the pressing plate 4 out of the grinding box 2 through the handle 5, and then pour the suspension to be ground into the grinding box 2. At this time, the suspension falls on the filter screen 9. After the suspension to be ground is poured in, the pressing plate 4 is placed in the grinding box 2. At this time, the pressing plate 4 is engaged with the limiting cylinder 13 and the limiting rod 15, so as to control the pressing plate 4 to move up and down only in the grinding box 2. Then, the weight 7 is installed in the mounting groove 6 on the top surface of the pressing plate 4. The suspension to be ground is pressed downward by the gravity of the weight 7 and the pressing plate 4, which avoids splashing of the suspension during crushing and helps to achieve a more uniform particle size distribution. This design can ensure the stability of the grinding process, reduce material loss, and reduce the risk of dust flying.

[0027] Step 2, start the servo motor 30, and drive the driving bevel gear 29 to rotate through the servo motor 30, and the driving bevel gear 29 is meshed with the driven bevel gear 28 for transmission. When the driving bevel gear 29 rotates, it drives the driven bevel gear 28 to rotate, and then controls the rotation of the rotating shaft 27. A connecting block 17 is installed on the upper end of the rotating shaft 27, and a spline shaft 18 is installed on the top surface of the connecting block 17. The upper end of the spline shaft 18 is placed in the spline groove 16. When the rotating shaft 27 rotates, the connecting block 17 is controlled to rotate, and then the spline shaft 18 is controlled to rotate. When the rotating column 11 drives the crushing rod 12 to rotate, the suspension is crushed.

[0028] Step 3: When the suspension is crushed, the spline shaft 18 rotates, the lever 37 is controlled to swing back and forth, and the filter screen 9 is controlled to shake, so that the suspension stuck on the surface of the filter screen 9 is shaken off, so as to avoid the suspension clogging the filter screen 9, and ensure that the suspension passes through the filter screen 9 smoothly and enters the next crushing or grinding process. This design effectively solves the problem of the suspension clogging the filter screen 9 and improves the grinding efficiency. Step 4: When the suspension is crushed and falls into the bottom of the grinding box 2, the grinding roller 20 touches the suspension and rotates. This design can achieve efficient grinding of the suspension. The revolution of the grinding roller 20 ensures the uniform distribution of the suspension in the grinding box 2, while the rotation further refines the suspension particles and improves the grinding efficiency and quality. When the suspension is ground, it falls into the guide box 21 through the gap between the grinding box 2 and the connecting block 17.

[0029] Step 5, when the ground suspension falls into the material guide box 21, the suspension at one end is moved to the lower end by the design of one end being high and the other end being low in the material guide box 21, thereby controlling part of the suspension to be moved out of the discharge pipe 22, and then starting the external air pump to ventilate the air pipe 24, thereby blowing the suspension at the high end that has not moved to the bottom end, thereby completely blowing the ground suspension out of the discharge pipe 22; and then all electrical equipment is powered off. This solution integrates the grinding, material guiding and discharging processes into one system, reduces the connection and material transfer links between equipment, improves the overall operating efficiency of the equipment, and reduces the operation complexity and the investment, use and maintenance costs of the equipment.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
