Description

Technical Field

[0001] The present invention relates to the technical field of drug cooling, and specifically to a cooling device and method for grinding materials in the production of pesticide water suspension concentrates. Background Art

[0002] Pesticide water suspension concentrate is a suspension formed by finely grinding an insoluble solid pesticide technical material and additives and uniformly dispersing them in an aqueous medium. Its particle size is controlled below 4 microns, and it has good dispersibility, stability and high biological activity. It is not flammable or explosive, has a relatively large specific gravity, and a small packaging volume, and has significant advantages in terms of safety and environmental protection compared with other pesticide formulations. It is one of the important new water-based pesticide formulations in modern agriculture. In the production process of pesticide water suspension concentrates, the active ingredient and additive filler need to be mixed evenly to form a suspension aqueous solution, and then the particles of the material are ground finer by a grinder. During the grinding process, a large amount of heat is generated due to the mutual extrusion and collision of the abrasive and material particles, which is not convenient for subsequent operations. Therefore, it is necessary to cool it through a cooling device.

[0003] As disclosed in a Chinese patent: A cooling device for grinding materials in the production of pesticide water suspension concentrates, application number: CN201721324743.X, includes a cooling water tower, a feed pipe and a discharge pipe. The top of the cooling water tower is provided with a pressure balance port. The feed pipe used in this cooling device for grinding materials in the production of pesticide water suspension concentrates is larger than a general feed pipe, so that more materials can enter at the same time. When the materials enter the water distributor, they will respectively enter the upper condensing pipe, the circular condensing pipe and the lower condensing pipe. The upper condensing pipe, the circular condensing pipe and the lower condensing pipe are all close to the inside of the cooling water tower, and are spiral from top to bottom. Moreover, the upper condensing pipe and the circular condensing pipe, as well as the circular condensing pipe and the lower condensing pipe, do not contact each other. Therefore, all three condensing pipes are still in contact with the cooling water, and the amount of materials processed in each condenser is still very small, and the path traveled is longer, so the condensing effect is higher.

[0004] However, in the above technical solution, when the material needs to be cooled, the outer wall of the condensing pipe is cooled by the cooling water inside the cooling water tower, and then the material in the condensing pipe is cooled by the cooled outer wall of the condensing pipe, and the cooling is carried out in a single direction from the outside to the inside. This cooling method has an inherent limitation, that is, the cooling process starts from the outer wall of the condensing pipe and then gradually transfers to the material inside the pipe. Since heat transfer requires time and temperature difference as the driving force, inside the condensing pipe, the material close to the outer wall will be cooled first and the temperature will drop rapidly. However, as the cooling process progresses, the material far from the outer wall of the condensing pipe has a longer heat conduction path, and the heat transfer efficiency will gradually decrease, resulting in slower cooling of the material far from the outer wall of the condensing pipe and reducing the cooling efficiency. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a cooling device and method for grinding materials in the production of pesticide water suspension concentrates, which can effectively solve the problem in the background art that when the material needs to be cooled, the outer wall of the condensation pipe is cooled by the cooling water in the cooling water tower, and then the material in the condensation pipe is cooled by the outer wall of the cooled condensation pipe, with one-way cooling from the outside to the inside. This cooling method has an inherent limitation, that is, the cooling process starts from the outer wall of the condensation pipe and then gradually transfers to the material inside the pipe. Since heat transfer requires time and temperature difference as the driving force, inside the condensation pipe, the material near the outer wall will be cooled first and the temperature will drop rapidly. However, as the cooling process progresses, the material far from the outer wall of the condensation pipe has a longer heat conduction path, and the heat transfer efficiency will gradually decrease, resulting in slower cooling of the material far from the outer wall of the condensation pipe and reducing the cooling efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a cooling device for grinding materials in the production of pesticide aqueous suspension concentrates, including a cooling water tower 1. A cooling tank 2 is arranged on the cooling water tower 1. A cooling pipe 3 is fixedly arranged in the cooling tank 2. A first water discharge pipe 4 and a first water inlet pipe 5 are respectively arranged on both sides of the cooling pipe 3. A second water inlet pipe 6 and an overflow port 7 are arranged on one side of the cooling water tower 1. A pressure balance port 8 and a sewage discharge port 9 are respectively arranged on the upper and lower sides of the cooling water tower 1.

[0021] As Figure 3 and Figure 4 shown, the cooling pipe 3 includes a cooling pipe main body 301. A water passing pipe 302 is arranged in the inner cavity of the cooling pipe main body 301. A plurality of hollow pipes 303 are arranged on the water passing pipe 302; The feed pipe 304 and the discharge pipe 305 are respectively and fixedly arranged on both sides of the cooling pipe main body 301. A second water discharge pipe 306 and a third water inlet pipe 307 are respectively and fixedly arranged on the feed pipe 304 and the discharge pipe 305.

[0022] Through the above technical solution, when it is necessary to cool the material, first inject cooling water into the cooling tank 2 to continuously cool the cooling pipe main body 301 and the hollow pipe 303. At the same time, input the cooling water into the third water inlet pipe 307 through the first water inlet pipe 5, then input the cooling water into the water passing pipe 302 through the third water inlet pipe 307, and then discharge the excess cooling water in the water passing pipe 302 through the second water outlet pipe 306 to continuously cool the water passing pipe 302. Then, the second water outlet pipe 306 discharges the cooling water to a designated place through the first water outlet pipe 4. Subsequently, input the material into the inner cavity of the cooling pipe main body 301 through the feeding pipe 304, and cool both sides of the material in the inner cavity of the cooling pipe main body 301 through the cooling pipe main body 301 and the water passing pipe 302, increasing the cooling contact area of the material, thereby accelerating cooling, improving the cooling efficiency and quality, and using the hollow pipe 303 to disperse the moving material and cool the central layer of the material, further improving the cooling efficiency and quality.

[0023] As Figure 5 shown, the second water inlet pipe 6 includes a water inlet pipe main body 601, and a shunt port 602 is provided on the water inlet pipe main body 601; On one side of the water inlet pipe main body 601, an annular thread groove 603 is provided. An internal thread ring 604 is provided on the annular thread groove 603. On one side of the internal thread ring 604, a water delivery pipe 605 is provided. On the side of the water inlet pipe main body 601 close to the water delivery pipe 605, a groove 606 is provided, and a filter plate 607 is provided in the groove 606.

[0024] Through the above technical solution, when it is necessary to inject cooling water into the cooling tank 2 and the first water inlet pipe 5, first inject the cooling water into the water delivery pipe 605, inject the cooling water into the water inlet pipe main body 601 through the water delivery pipe 605, and use the filter plate 607 to filter the incoming cooling water to prevent impurities in the cooling water from blocking the water passing pipe 302 and the hollow pipe 303. Then, part of the cooling water is injected into the cooling tank 2 through the water inlet pipe main body 601, and the other part of the cooling water is injected into the first water inlet pipe 5 through the shunt port 602. When it is necessary to clean or replace the filter plate 607, first rotate the water delivery pipe 605. The water delivery pipe 605 drives the internal thread ring 604 to rotate, separating the water delivery pipe 605 from the water inlet pipe main body 601, so that the filter plate 607 can be taken out of the groove 606, facilitating the staff to clean and replace the filter plate 607.

[0025] A cooling method for grinding materials in the production of a pesticide aqueous suspension agent includes the following steps: Step 1: Inject cooling water into the cooling tank 2 and the first water inlet pipe 5 through the second water inlet pipe 6, and the first water inlet pipe 5 injects part of the cooling water into part of the components of the cooling pipe 3; Step 2: Drain the excess cooling water in the cooling tank 2 and the cooling pipe 3 through the overflow port 7 and the first water outlet pipe 4 respectively; Step 3: After the injection of the cooling water is completed, inject the material to be cooled into the cooling pipe 3, and cool the material through the cooperation of the cooling pipe 3 and the cooling water.

[0026] Working principle: In the present invention, first, the cooling water is injected into the second water inlet pipe 6, and then the cooling water entering through the filter plate 607 is filtered. Subsequently, the cooling water is respectively injected into the cooling tank 2 and the first water inlet pipe 5 through the second water inlet pipe 6. The first water inlet pipe 5 inputs the cooling water into the third water inlet pipe 307, and then the cooling water is input into the water passing pipe 302 through the third water inlet pipe 307 to continuously cool the water passing pipe 302. At the same time, the cooling water in the cooling tank 2 continuously cools the cooling pipe main body 301 and the hollow pipe 303, and the excess cooling water in the cooling tank 2 and the cooling pipe 3 is respectively drained through the overflow port 7 and the first water outlet pipe 4. Subsequently, the material is input into the inner cavity of the cooling pipe main body 301 through the feeding pipe 304, and the material in the inner cavity of the cooling pipe main body 301 is cooled on both sides simultaneously through the cooling pipe main body 301 and the water passing pipe 302, increasing the cooling contact area of the material, thereby accelerating the cooling, improving the cooling efficiency and quality, and using the hollow pipe 303 to disperse the moving material and cool the central layer of the material, further improving the cooling efficiency and quality.

[0027] Among them, when the material needs to be cooled, first, the cooling water is injected into the cooling tank 2 to continuously cool the cooling pipe main body 301 and the hollow pipe 303. At the same time, the cooling water is input into the third water inlet pipe 307 through the first water inlet pipe 5, and then the cooling water is input into the water passing pipe 302 through the third water inlet pipe 307. Subsequently, the excess cooling water in the water passing pipe 302 is discharged through the second water outlet pipe 306 to continuously cool the water passing pipe 302. Then, the second water outlet pipe 306 discharges the cooling water to the designated place through the first water outlet pipe 4. Subsequently, the material is input into the inner cavity of the cooling pipe main body 301 through the feeding pipe 304, and the material in the inner cavity of the cooling pipe main body 301 is cooled on both sides simultaneously through the cooling pipe main body 301 and the water passing pipe 302, increasing the cooling contact area of the material, thereby accelerating the cooling, improving the cooling efficiency and quality, and using the hollow pipe 303 to disperse the moving material and cool the central layer of the material, further improving the cooling efficiency and quality.

[0028] Among them, when it is necessary to inject cooling water into the cooling tank 2 and the first water inlet pipe 5, first inject the cooling water into the water delivery pipe 605. The cooling water is injected into the main body 601 of the water inlet pipe through the water delivery pipe 605, and the entering cooling water is filtered by the filter plate 607 to prevent impurities in the cooling water from blocking the water passing pipe 302 and the hollow pipe 303. Then, a part of the cooling water is injected into the cooling tank 2 through the main body 601 of the water inlet pipe, and another part of the cooling water is injected into the first water inlet pipe 5 through the diversion port 602. When it is necessary to clean or replace the filter plate 607, first rotate the water delivery pipe 605. The water delivery pipe 605 drives the internal thread ring 604 to rotate, so that the water delivery pipe 605 is separated from the main body 601 of the water inlet pipe, and thus the filter plate 607 can be taken out from the groove 606, which is convenient for the staff to clean and replace the filter plate 607.

For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is impossible to enumerate all the implementation manners here. All obvious changes or variations derived from the technical solutions of the present invention are still within the protection scope of the present invention.
