Description

Technical Field

[0001] The invention relates to the field of pesticide emulsion production technology, specifically a reaction apparatus and production line for producing pesticide emulsions. Background Technology

[0002] Generally, pesticides used in the processing of water-in-oil emulsions should ideally have a water solubility of less than 1000 mg / L. Because these formulations contain a large amount of water, pesticides that are not sensitive to hydrolysis are easier to process into chemically stable water-in-oil emulsions.

[0003] Existing pesticide emulsions often leave a large amount of emulsion residue in the reaction vessel after synthesis. When the next reaction is carried out, the residual emulsion in the reaction vessel affects the concentration ratio of the reactants. In addition, it is difficult to clean the pesticide emulsion residue in the reaction vessel. Traditional water rinsing methods are not enough to thoroughly clean the pesticide emulsion, which affects the yield of finished pesticide emulsion products. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a reaction apparatus and production line for producing pesticide water-in-oil emulsions. It has the advantages of thoroughly cleaning residual pesticide water-in-oil emulsions in the reaction vessel and ensuring that the synthesis and cleaning steps in the reaction vessel do not interfere with each other. This solves the problem that traditional water rinsing methods are difficult to thoroughly clean pesticide water-in-oil emulsions, thus affecting the yield of finished pesticide water-in-oil emulsions.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the invention provides the following technical solution:

[0008] A reaction apparatus and production line for producing pesticide emulsions include a main body, a partition plate fixedly connected to the inner wall of the main body, a through hole at the top of the partition plate, a reaction vessel fixedly connected to the top of the partition plate, an inner cylinder fixedly connected to the bottom inner wall of the reaction vessel, a leakage hole at the bottom of the reaction vessel, a feed pipe fixedly connected to the left side of the reaction vessel, a top cover fixedly connected to the top of the main body, a motor fixedly connected to the top of the top cover, a lead screw fixedly connected to the output end of the motor, and the bottom of the lead screw rotatably connected to the bottom of the inner wall of the inner cylinder.

[0009] With the above technical solution, when the device is in use, after the synthesis of pesticide water emulsion is completed, it is discharged from the drain pipe. At this time, the reactor is cleaned by spraying water from the water storage pipe into the reactor through the spray nozzle. The motor is started to make the cleaning ball rod scrub the reactor. Finally, the waste liquid falls from the through hole into the accumulation hood and is then discharged from the drain pipe.

[0010] Preferably, a sleeve is threaded onto the outer surface of the lead screw, and a cleaning ball is fixedly connected to the bottom of the sleeve.

[0011] With the above technical solution, during the rotation of the lead screw, the sleeve will move downward along the surface of the lead screw, thereby allowing the cleaning ball rod to repeatedly scrub the inside of the reactor.

[0012] Preferably, water storage tanks are fixedly connected to both the left and right sides of the device body, and water pipes are fixedly connected to the top of the water storage tanks.

[0013] Using the above technical solution, and with the help of a water pump, clean water from the storage tank is injected into the water pipe.

[0014] Preferably, a water pump is provided on the outer surface of the water pipe, and a spray head is fixedly connected to the end of the water pipe away from the water storage tank.

[0015] With the above technical solution, the water in the pipe will flow to the spray head, and finally be sprayed onto the reactor by the spray head, making the cleaning rod wet and making it easier to clean the inside of the reactor.

[0016] Preferably, a pull plate is slidably connected to the inner surface of the partition, the outer surface of the pull plate is connected through to the left side of the device body, and an accumulation cover is fixedly connected to the bottom of the device body.

[0017] The above technical solution allows the pull plate to be pulled out of the partition as needed, or the pull plate to be placed inside the partition and pass through the through hole to block the through hole.

[0018] Preferably, the bottom of the accumulation cover is fixedly connected to a drain pipe, and a valve is provided on the outer surface of the drain pipe.

[0019] With the above technical solution, the waste liquid after cleaning falls into the accumulation hood, and finally the valve is opened to discharge the waste liquid from the drain pipe.

[0020] Preferably, based on the above-described apparatus for producing pesticide water-in-oil emulsions, a production line for producing pesticide water-in-oil emulsions is now proposed, comprising the following steps:

[0021] S101, the raw materials are introduced into the reaction vessel inside the device body through the feed pipe to complete the synthesis;

[0022] S102. When cleaning the reactor, the cleaning rod rubs the inner wall of the reactor to brush away the residual pesticide emulsion inside the reactor.

[0023] S103. Spray water from the spray nozzle onto the reactor to wet the cleaning rod and scrub away the pesticide emulsion on the inner wall of the reactor.

[0024] S104. The waste liquid washed off will leak out from the leak hole at the bottom of the reactor.

[0025] S105, Cleaning complete.

[0026] Preferably, the production line of the reaction apparatus for producing pesticide water-in-oil emulsions described above includes the following steps:

[0027] S201. Before synthesizing pesticide emulsions, the raw materials need to be transported from the feed pipe to the reaction vessel;

[0028] S202. Push the pull plate inward so that it passes through the through hole inside the partition plate and blocks the through hole to prevent the raw materials in the reactor from leaking out of the leak hole and falling into the accumulation hood through the through hole.

[0029] S203. When cleaning the reactor, the pull plate should be pulled to the left to prevent it from blocking the through hole and thus not affecting the cleaning process of the reactor.

[0030] S204, thereby achieving the goal of allowing the synthesis and cleaning steps to be carried out separately in the reactor without affecting each other.

[0031] Compared with the prior art, the invention provides a reaction apparatus and production line for producing pesticide water-in-oil emulsions, which has the following beneficial effects:

[0032] 1. This reaction device and production line for producing pesticide emulsions, by starting the motor on the top of the cover, drives the lead screw to rotate in the inner cylinder of the reactor. The rod sleeve moves downward along the lead screw, thereby allowing the cleaning ball rod to rub against the inner wall of the reactor. In conjunction with the water spraying of clean water onto the reactor by the water spray head, the cleaning ball rod is moistened, making it easier to scrub away the pesticide emulsion on the inner wall of the reactor, thus achieving the effect of thoroughly cleaning the residual pesticide emulsion in the reactor.

[0033] 2. The reaction apparatus and production line for producing pesticide water-in-oil emulsions, by pushing the pull plate inward during the synthesis of pesticide water-in-oil emulsions, allows the pull plate to pass through the through hole inside the partition plate, thus blocking the through hole. When cleaning the reaction vessel, the pull plate needs to be pulled to the left to prevent it from blocking the through hole, so as not to affect the cleaning process of the reaction vessel. This achieves the effect that the synthesis and cleaning steps in the reaction vessel do not affect each other. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0039] Example 1, as Figure 1-3 As shown, the invention provides a reaction apparatus and production line for producing pesticide water-based emulsions. When the apparatus is in use, after the pesticide water-based emulsion is synthesized in the reaction vessel 4, the motor 9 is started to drive the lead screw 10 to rotate, thereby causing the rod sleeve 11 to move down. At the same time, the cleaning ball rod 12 moves down and rubs the inner wall of the reaction vessel 4. Meanwhile, clean water in the water storage tank 13 is injected into the water pipe 14 and sprayed onto the reaction vessel 4 by the water spray head 16. The wet cleaning ball rod 12 can more easily scrub away the pesticide water-based emulsion residue on the inner wall of the reaction vessel 4.

[0040] Example 2, as Figure 2 and Figure 3 As shown, since the sleeve 11 is threaded onto the surface of the lead screw 10, the sleeve 11 will gradually move down during the rotation of the lead screw 10, thereby driving the cleaning ball rod 12 down to clean the reactor 4. When cleaning the reactor 4, the pull plate 17 needs to be pulled to the left so that it no longer blocks the through hole 3 and does not affect the cleaning process of the reactor 4.

[0041] The wiring diagrams of the water pump 15 and motor 9 in the invention are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the water pump 15 and motor 9 will not be explained in detail.

[0042] Working Principle: In this reaction apparatus and production line for producing pesticide emulsions, raw materials enter the reaction vessel 4 inside the main body 1 through the feed pipe 7. The pesticide emulsion is synthesized under high temperature and pressure. Afterwards, the reaction vessel 4 needs to be cleaned promptly. This is done by first starting the motor 9 on top of the top cover 8, which drives the lead screw 10 to rotate within the inner cylinder 5 of the vessel. The sleeve 11 moves downwards along the lead screw 10, causing the cleaning ball rod 12 to rub against the inner wall of the reaction vessel 4, thus scrubbing the reaction vessel 4. The residual pesticide emulsion inside the reactor 4 is removed by water pump 15, which pumps water from storage tank 13 into water pipe 14. The water is then sprayed onto reactor 4 by spray nozzle 16, wetting cleaning rod 12 and making it easier to scrub away the pesticide emulsion from the inner wall of reactor 4. The waste liquid from scrubbing leaks out through the drain hole 6 at the bottom of reactor 4 and falls into accumulation hood 18 through through hole 3. Finally, valve 20 is opened to discharge the waste liquid from accumulation hood 18 through drain pipe 19. This achieves the goal of thoroughly cleaning the residual pesticide emulsion in reactor 4. Before synthesizing the pesticide emulsion, the raw materials need to be transported to reactor 4 through feed pipe 7. In the middle, the pull plate 17 is pushed inward so that it passes through the through hole 3 inside the partition plate 2, blocking the through hole 3 and preventing the raw materials in the reactor 4 from leaking out of the leak hole 6 and falling into the accumulation hood 18 through the through hole 3. When cleaning the reactor 4, the pull plate 17 needs to be pulled to the left so that it no longer blocks the through hole 3 and does not affect the cleaning process of the reactor 4, thus achieving the purpose of the synthesis and cleaning steps in the reactor 4 being carried out separately without affecting each other.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
