Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide processing technology, and in particular to a vacuum degassing device for the production of pesticide adjuvants. Background Technology
[0002] Pesticide adjuvants are an important component of pesticides, effectively improving their biological activity, safety, stability, and application efficacy. However, many adjuvant mixtures are prone to bubble formation during production, which can affect the quality and performance of pesticide adjuvants. Bubbles can lead to uneven dispersion in the mixture, affecting solubility and stability, and even causing the loss of active pesticide components.
[0003] Methods for removing air bubbles from pesticide adjuvant mixtures mainly employ physical methods such as vibration and ultrasonic treatment. However, these methods suffer from drawbacks such as low efficiency, complex operation, and susceptibility to environmental influences. Vacuum degassing technology, with its advantages of high efficiency and safety, is widely used in various industrial fields such as separation, concentration, and drying. Particularly in the chemical and food processing industries, vacuum degassing technology is widely used to remove gases from liquids, improving product quality and yield.
[0004] Due to varying feed rates each time, significant quality differences arise between batches of produced products. These differences complicate subsequent quality inspection and product application. Uncontrolled feed rates can lead to excessive feed, prolonging degassing time, and even potentially causing equipment malfunctions, such as liquid overflow due to overfeeding. Therefore, a vacuum degassing device for pesticide adjuvant production is proposed to address these issues. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a vacuum degassing device for pesticide adjuvant production, comprising a tank 1. The tank 1 serves as the main structure for containing the pesticide adjuvant solution, providing a relatively closed and stable space for the entire degassing process. Its shape and material design can adapt to internal pressure changes and the requirements for cooperation with other components. A top cover 2 is slidably connected to the top of the tank 1. The sliding connection between the top cover 2 and the tank 1 allows the top cover 2 to be opened and closed relatively flexibly, facilitating subsequent operations such as feeding, discharging, and internal maintenance of the equipment. At the same time, when closed, it ensures that a relatively sealed environment is formed inside the tank 1, which is conducive to creating vacuum conditions for degassing operations.
[0033] A motor 3 is fixedly connected to the top of the top cover 2. This fixed connection allows the motor 3 to drive other components via a transmission structure, enabling control of feeding and other processes. The stable connection ensures the motor's stability during operation, preventing displacement due to vibration or other factors that could affect normal equipment operation. A follower plate 4 is fixedly connected to the top of the motor 3. Driven by the motor 3, the follower plate 4 moves accordingly. As a link in the transmission chain, it transmits power and changes the direction of force, converting the rotational motion of the motor 3 into a form suitable for the movement of subsequent components, thus driving related components to work collaboratively. A driven plate 5 is rotatably connected to the end of the follower plate 4 furthest from the motor 3. This rotatable connection between the follower plate 5 and the follower plate 4 makes force transmission more flexible, allowing the direction and state of movement to be changed within a certain angle range according to the equipment's operating requirements. This further coordinates with subsequent components to accurately complete corresponding actions, ensuring the orderly progress of the entire feeding process.
[0034] A sliding plate 6 is slidably connected to the end of the driven plate 5 furthest from the follower plate 4. The sliding plate 6, through its slidable connection to the driven plate 5, can move linearly under the drive of the driven plate 5. This movement plays a crucial role in precisely controlling the opening and closing of the feed inlet 21 and its alignment with the feed pipe 8, ensuring that the pesticide solution flows accurately into the tank 1 according to the set requirements. The inner wall of the sliding plate 6 has a feed inlet 21, which serves as the channel for the pesticide solution to enter the tank 1. The size and position of the feed inlet 21 are designed to match the entire feeding system. Only when the feed inlet 21 is accurately aligned with the feed pipe 8 can the solution flow smoothly into the tank 1, avoiding situations where the flow rate is too fast, causing splashing, or too slow, affecting production efficiency. A cleaning agitator is slidably connected to the inner wall of the tank 1. This agitator, through its slidable connection to the inner wall of the tank 1, also cleans the inner wall during agitation, preventing the solution from adhering to the inner wall for extended periods, thus avoiding impacts on equipment performance and the quality of subsequent products.
[0035] The inner wall of the top cover 2 is fixedly connected to the feed pipe 8, which serves as the external interface for the pesticide solution to enter the tank 1. It connects to external feeding equipment, and its pipe diameter and material design meet the requirements for solution delivery, enabling the pesticide solution to be smoothly delivered into the tank 1. Furthermore, it cooperates with the feed inlet 21 on the slide plate 6 to achieve accurate solution injection. The inner wall of the fixing block 7 is fixedly connected to the outer wall of the feed pipe 8. The fixing block 7 provides fixation and protection for the feed pipe 8, preventing displacement or damage due to vibration or other factors during equipment operation, thus ensuring the stability and unobstructed flow of the feed channel.
[0036] The top of the top cover 2 has a motor mounting hole 22, which provides a precise installation position for the motor 3. The hole diameter matches the outer diameter of the motor 3, allowing the motor 3 to be tightly and securely installed on the top cover 2. This prevents the motor from shaking during operation and affecting its control of the feeding operation through the transmission structure. The outer wall of the motor 3 is fixedly connected to the inner wall of the motor mounting hole 22. This fixed connection method ensures the secure installation of the motor 3, allowing it to stably output power and drive the follower plate 4 and other components to move accordingly. This enables precise control of the slide plate 6 and the feed inlet 21, ensuring the normal feeding process of the pesticide solution.
[0037] Reference Figure 1 , Figure 3 and Figure 4 The stirring assembly includes a second motor 9, which serves as the power source for the stirring assembly, providing a stable driving force for the rotation of the rotating rod 10 and the stirring plates 11. Its output torque and speed can be adjusted reasonably according to factors such as the properties of the pesticide adjuvant and the amount of solution in the tank 1 to achieve the best stirring effect and ensure that air bubbles in the solution can fully escape. The rotating rod 10 is fixedly connected to the drive end of the second motor 9. Driven by the second motor 9, the rotating rod 10 rotates, transmitting motor power to the stirring plates 11. Its length and strength are designed to meet the requirements for stable rotation within the tank 1. Multiple stirring plates 11 are fixedly connected to the outer wall of the rotating rod 10, evenly distributed on its outer wall. As the rotating rod 10 rotates, the stirring plates 11 can comprehensively agitate the pesticide solution within the tank 1, increasing the solution's fluidity.
[0038] Two stirring plates 11 are fixedly connected to a fixing plate 12 at the end away from the rotating rod 10. The fixing plate 12 connects the adjacent stirring plates 11, enhancing the overall stability of the stirring plate 11 structure and preventing deformation or loosening during high-speed rotation and stirring, thus ensuring continuous and effective stirring. Two telescopic columns 13 are fixedly connected to the side of the fixing plate 12 away from the stirring plate 11. The telescopic columns 13 serve two purposes: firstly, to connect the fixing plate 12 to the rubber block 15; secondly, their telescopic nature allows them to adapt to the positional changes of the rubber block 15 as it scrapes the inner wall of the tank 1 due to different resistances, ensuring that the rubber block 15 always maintains good contact with the inner wall of the tank 1.
[0039] A rubber block 15 is fixedly connected to one end of the telescopic column 13 away from the fixed plate 12. The rubber block 15 is in contact with the inner wall of the tank 1. During the rotation of the stirring plate 11, the rubber block 15 moves along with it and scrapes the inner wall of the tank 1. This can effectively scrape off the solution adhering to the inner wall of the tank 1 and allow it to re-participate in the stirring and degassing process, reducing the residue of solution on the inner wall of the tank 1, further improving the product yield and the cleanliness of the equipment, and avoiding the occurrence of subsequent product quality issues such as bacterial growth due to solution residue.
[0040] The outer wall of the rotating rod 10 is fixedly connected to the inner wall of the top cover 2. This fixed connection ensures the stability of the rotating rod 10 during rotation. The position and fixing method of the connection point are designed to allow the rotating rod 10 to rotate smoothly under the drive of the motor 9, driving the stirring plate 11 to fully stir the pesticide solution in the tank 1. At the same time, the force generated by the rotation will not damage the top cover 2, ensuring the reliable operation of the entire stirring system. The side of the rubber block 15 away from the stirring plate 11 is slidably connected to the inner wall of the top cover 2. This sliding connection between the rubber block 15 and the inner wall of the top cover 2 allows the rubber block 15 to maintain a stable trajectory under the constraint of the inner wall of the top cover 2 when it rotates with the stirring plate 11 and scrapes the inner wall of the tank 1. This better fulfills its function of scraping the solution off the inner wall of the tank 1, reducing solution residue, and improving the cleanliness of the equipment and product quality.
[0041] A spring 14 is fixedly connected to the side of the rubber block 15 away from the tank 1. One end of the spring 14 is fixed to the rubber block 15. When the rubber block 15 encounters different resistances while scraping the inner wall of the tank 1, the spring 14 can buffer this resistance through its own expansion and contraction characteristics, ensuring that the rubber block 15 always maintains good contact with the inner wall of the tank 1, ensuring the stability of the scraping effect, and also providing a certain degree of protection for the rubber block 15, preventing damage caused by excessive resistance. The end of the spring 14 away from the rubber block 15 is fixedly connected to the outside of the fixing plate 12. This fixed connection method makes the spring 14, the rubber block 15 and the fixing plate 12 form an organic whole, working together during the rotation of the stirring plate 11. The elasticity of the spring 14 is used to adjust the contact pressure between the rubber block 15 and the inner wall of the tank 1, effectively increasing the contact area, thereby more fully scraping off the solution on the inner wall of the tank 1, further improving the stirring and degassing effect, and ensuring the improvement of product quality.
[0042] The outer wall of the telescopic column 13 is slidably connected to the inner wall of the spring 14. The telescopic column 13 slides on the inner wall of the spring 14, which not only ensures that its own telescopic function is not affected, but also plays a guiding and supporting role during the telescopic process of the spring 14. This makes the connection between the spring 14, the rubber block 15 and the fixed plate 12 more stable, and the entire structure can play a more reliable role in the stirring process, thereby improving the overall performance and working efficiency of the equipment.
[0043] Reference Figures 1 to 3 A base plate 18 is fixedly connected to the bottom of the tank 1, providing a stable support foundation for the tank 1. Its area and strength design ensure that the tank 1 can be placed stably on the ground or a corresponding installation platform, bearing the weight of the tank 1 and the internal solution, and providing a reliable fixing position for other components installed at the bottom of the tank 1, such as the electric pneumatic cylinder 19. An electric pneumatic cylinder 19 is fixedly connected to the top of the base plate 18. The electric pneumatic cylinder 19 obtains a stable installation position through its fixed connection with the base plate 18. It can generate extension and retraction movements according to the instructions of the control system, providing power for the lifting and lowering of the top cover 2, realizing the tight closing or opening of the top cover 2 and the tank 1, ensuring that the inside of the tank 1 is in a sealed state during the degassing process, and also facilitating operations such as feeding, discharging, and internal inspection and maintenance of the equipment.
[0044] An operating block 20 is fixedly connected to the top of the electric pneumatic cylinder 19. The operating block 20 serves as the connecting component between the electric pneumatic cylinder 19 and the second motor 9, transmitting the extension and retraction force of the electric pneumatic cylinder 19 to the second motor 9, driving the second motor 9 and the entire stirring assembly to move up and down. This allows the stirring assembly to operate at different heights within the tank 1, improving the comprehensiveness and uniformity of the stirring. The side of the operating block 20 furthest from the electric pneumatic cylinder 19 is fixedly connected to the outer wall of the second motor 9. This fixed connection ensures a firm and reliable connection between the operating block 20 and the second motor 9, allowing the power generated by the electric pneumatic cylinder 19 to be accurately transmitted to the second motor 9, ensuring the stirring assembly moves normally within the tank 1 according to the set requirements.
[0045] The control assembly includes a tank 1, which serves as the carrier of the entire control assembly. Its internal structure and connection method provide the basic conditions for the installation and normal operation of components such as the discharge pipe 16, and also provide guidance and containment space for the flow of the solution during the discharge process. The discharge pipe 16 is fixedly connected to the inner wall of the tank 1, and the discharge pipe 16 is fixed at a suitable position on the inner wall of the tank 1.
[0046] A valve 17 is installed on the outside of the discharge pipe 16. The valve 17 is installed on the discharge pipe 16 and can accurately control the flow rate and speed of the discharge. By adjusting the opening of the valve 17, the operator can accurately release an appropriate amount of pesticide adjuvant solution according to the production plan, avoiding waste caused by the solution flowing out too fast or affecting production efficiency by flowing out too slowly. It also facilitates the separate collection and subsequent processing of different batches of products.
[0047] Working principle: When the electric pneumatic cylinder 19 is turned on, the top cover 2 is lowered to close the tank 1. When the motor 1 3 is turned on, the follower plate 4 is driven to pull the slide plate 6 so that the feed port 21 is aligned with the feed pipe 8 and the pesticide solution flows into the tank 1. After the pesticide solution is injected, the motor 1 3 is turned on to move the slide plate 6 to block the feed pipe 8, which is convenient for workers to operate and will not cause excessive waste of solution. It also increases the defoaming time and facilitates control.
[0048] When the motor 29 is turned on, it drives the rotating rod 10 to rotate, and the external stirring plate 11 stirs the pesticide. The vacuum environment inside facilitates defoaming, which improves the stability of the pesticide adjuvant. The rubber block 15 connected to the end of the stirring plate 11 away from the rotating rod 10 scrapes the inner wall of the tank 1, reducing the amount of solution adhering to the inner wall of the tank 1 and fully increasing the stirring. The telescopic column 13 and spring 14 connecting the rubber block 15 and the fixed plate 12 squeeze the rubber block 15, which can effectively increase the contact area and clean the inner wall of the tank 1, preventing the solution from adhering to the inner wall for a long time, which would affect the performance of the equipment and the quality of the subsequent products.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
