Description

Technical Field

[0001] This utility model relates to the field of pesticide equipment technology, and in particular to a device for preventing the volatilization of adjuvants used in pesticide production. Background Technology

[0002] In pesticide production, the storage quality of liquid adjuvants directly affects the stability and effectiveness of the finished pesticide product. Liquid adjuvants often contain volatile components; excessive evaporation during storage can not only alter adjuvant concentrations, affecting the accuracy of subsequent production formulations, but also lead to raw material waste and even safety hazards or environmental pollution due to the diffusion of volatiles. Therefore, effectively suppressing the volatilization of liquid adjuvants has become a critical issue that urgently needs to be addressed in the pesticide production and storage process.

[0003] Traditional storage devices often use simple caps with threaded connections for the feed inlet, which has limited sealing performance. After prolonged use, gaps can easily appear due to aging of the seals or loosening of the connections, causing adjuvant vapors to continuously evaporate from the gaps. At the same time, the evaporation rate of adjuvants is closely related to the gas composition in the storage space. In existing devices, adjuvants are often directly exposed to air, and oxygen and other components in the air may react with the adjuvants, accelerating their deterioration and promoting volatilization. To solve the above problems, this application proposes an adjuvant anti-vaporization device for pesticide production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for preventing the volatilization of adjuvants in pesticide production. This device uses a threaded sealing cap that works in conjunction with the feed hopper, and a sealing ring to enhance the initial sealing effect. A sealing block in the sealing mechanism can create a secondary seal on the feed channel, significantly reducing the amount of adjuvant volatilization. The injection of inert gas allows air to be expelled from the storage space, placing the adjuvant in an inert gas atmosphere and reducing deterioration and volatilization caused by the reaction of air components with the adjuvant.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for preventing the volatilization of adjuvants used in pesticide production includes a storage tank. A feed hopper is fixedly connected to the top of the storage tank, and a sealing cap is threadedly connected to the top of the feed hopper. A sealing mechanism is provided inside the storage tank. An agitation mechanism is provided on the storage tank. An inert gas high-pressure tank is located on one side of the storage tank. A gas delivery pipe is fixedly connected to the top of the inert gas high-pressure tank. The end of the gas delivery pipe is fixedly connected to the bottom of the storage tank. A second solenoid valve and a one-way valve are fixedly connected to the outer wall of the gas delivery pipe. A vent pipe is fixedly connected to the top of the storage tank, and a safety valve is fixedly connected to the outer wall of the vent pipe. A control panel is fixedly connected to the front of the storage tank.

Two lifting rods are fixedly connected to the bottom of the sealing block. Each lifting rod passes through the U-shaped plate and is slidably connected to it. Each lifting rod passes through the storage box and is slidably sealed to it. A lifting ring is fixedly connected to the top of the two lifting rods. A spring is sleeved on the outer wall of each lifting rod. The two ends of each spring are fixedly connected to the storage box and the lifting ring, respectively.

[0007] Preferably, an O-ring is fixedly connected to the inner wall of the sealing cover, the inner ring of the O-ring abuts against the outer wall of the feed hopper, the outer wall of the feed hopper is provided with external threads, and the inner wall of the sealing cover is provided with internal threads that mate with the external threads.

[0008] Preferably, the outer wall of the lifting ring is provided with a protective sleeve, the protective sleeve is made of rubber, and the outer wall of the sealing cover is provided with anti-slip texture.

[0009] Preferably, the agitation mechanism includes a motor disposed on and fixedly connected to the side wall of the storage tank, a transmission rod fixedly connected to the output end of the motor, the transmission rod passing through the storage tank and rotatably and sealed thereto, and a plurality of agitating wheels distributed at equal intervals fixedly connected to the outer wall of the transmission rod.

[0010] Preferably, the bottom of the storage box is fixedly connected to a discharge hopper, and the outer wall of the discharge hopper is fixedly connected to a first electromagnetic valve.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. On the one hand, the threaded sealing cap cooperates with the feed hopper, and the sealing ring enhances the initial sealing effect; on the other hand, the sealing block in the sealing mechanism can form a secondary seal on the feed channel, and the spring force can ensure that the sealing block is always tightly fitted, greatly reducing the amount of additive volatilization.

[0012] 2. The stirring mechanism can periodically stir the liquid additives to avoid component precipitation and stratification caused by standing. This ensures the uniformity and effectiveness of the additives while preventing excessive local concentrations that could lead to increased volatilization.

[0013] 3. By injecting and replacing inert gas, the air in the storage space can be discharged, so that the additives are in an inert gas atmosphere, reducing the deterioration and volatilization caused by the reaction between air components and additives.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 A device for preventing the volatilization of adjuvants used in pesticide production includes a storage tank 1, which can be placed in an environment with a suitable temperature. A feed hopper 2 is fixedly connected to the top of the storage tank 1, providing a channel for injecting liquid adjuvants. A sealing cap 3 is threadedly connected to the top of the feed hopper 2, sealing the feed hopper 2 through the threaded connection to prevent adjuvant volatilization. The outer wall of the sealing cap 3 has anti-slip textures, which increase the friction between the hand and the sealing cap 3, facilitating rotational operation. An O-ring 4 is fixedly connected to the inner wall of the sealing cap 3, with the inner ring of the O-ring 4 abutting against the outer wall of the feed hopper 2. The abutment between the O-ring 4 and the outer wall of the feed hopper 2 further enhances the sealing performance between the sealing cap 3 and the feed hopper 2, reducing volatilization. The outer wall of the feed hopper 2 has external threads, and the inner wall of the sealing cap 3 has internal threads that mate with the external threads. The mating of the external and internal threads allows the sealing cap 3 to be stably installed on the feed hopper 2, while also facilitating disassembly for adjuvant injection.

[0019] The storage tank 1 is equipped with a sealing mechanism, which includes a sealing block 5 inside the storage tank 1. The sealing block 5 is used to seal the connection between the feed hopper 2 and the storage tank 1 to prevent the additive from evaporating from the feed hopper 2 during storage. A U-shaped plate 6 is fixedly connected to the top of the storage tank 1. The U-shaped plate 6 guides and limits the movement of the lifting rod 7, ensuring that the lifting rod 7 moves stably in the vertical direction. Two lifting rods 7 are fixedly connected to the bottom of the sealing block 5. Each lifting rod 7 passes through the U-shaped plate 6 and is slidably connected to it. The lifting rod 7 connects the sealing block 5 and the lifting ring 8, transmitting the moving force of the lifting ring 8 to the sealing block 5 to realize the lifting and lowering of the sealing block 5. Each lifting rod 7 passes through the storage tank 1 and is slidably connected to it, sealing the sliding... The connection ensures the airtightness of the storage box 1 when the lifting rod 7 moves, preventing the additive from leaking or evaporating. The tops of the two lifting rods 7 are fixedly connected to the lifting ring 8, which provides a force point for the operator. By pressing or releasing, the two lifting rods 7 move synchronously. The outer wall of the lifting ring 8 is equipped with a protective sleeve made of rubber. The rubber protective sleeve can cushion the pressure of the hand and enhance the comfort of the hand contact with the lifting ring 8. The outer wall of each lifting rod 7 is fitted with a spring 9. The two ends of each spring 9 are fixedly connected to the storage box 1 and the lifting ring 8, respectively. When the lifting ring 8 is pressed, the spring 9 is compressed and stores force. After release, the elastic force drives the lifting ring 8, the lifting rod 7 and the sealing block 5 to reset, realizing automatic sealing.

[0020] The storage tank 1 is equipped with an agitation mechanism, which includes a motor 10 fixedly connected to the side wall of the storage tank 1. The output end of the motor 10 is fixedly connected to a transmission rod 11, which transmits the power of the motor 10 to the stirring wheel 12, thereby rotating the stirring wheel 12. The transmission rod 11 passes through the storage tank 1 and is rotatably and sealingly connected to it. The rotatably and sealingly connected ensures the airtightness of the storage tank 1 when the transmission rod 11 rotates, preventing the additive from evaporating. Multiple stirring wheels 12 are fixedly connected to the outer wall of the transmission rod 11 at equal intervals. The stirring wheels 12 rotate with the transmission rod 11 to agitate the liquid additive in the storage tank 1, preventing the additive from settling.

[0021] A discharge hopper 13 is fixedly connected to the bottom of the storage tank 1, providing a discharge channel for the liquid additives in the storage tank 1 for easy access. A first solenoid valve 14 is fixedly connected to the outer wall of the discharge hopper 13, which is controlled by a control panel 21 to achieve precise control of the opening and closing of the discharge hopper 13. An inert gas high-pressure tank 15 is provided on one side of the storage tank 1. The inert gas high-pressure tank 15 is used to store high-pressure inert gas and provide an inert gas source for the storage tank 1. A gas supply pipe 16 is fixedly connected to the top of the inert gas high-pressure tank 15, which transports the inert gas in the inert gas high-pressure tank 15 to the storage tank 1. The end of the gas supply pipe 16 is fixedly connected to the bottom of the storage tank 1. Inputting inert gas from the bottom allows the gas to diffuse evenly into the liquid additives, gradually replacing the air in the storage tank 1. The outer wall of the gas supply pipe 16 is fixedly connected to... A second solenoid valve 17 is connected, which controls the opening and closing of the gas supply pipe 16 via the control panel 21 to adjust the amount of inert gas supplied. A one-way valve 18 is fixedly connected to the outer wall of the gas supply pipe 16. The one-way valve 18 can prevent the gas or additives in the storage tank 1 from flowing back into the inert gas high-pressure tank 15, ensuring the stability of the gas supply direction. A vent pipe 19 is fixedly connected to the top of the storage tank 1, which provides a channel for the air in the storage tank 1 to be discharged, so that the inert gas can fill the storage tank 1. A safety valve 20 is fixedly connected to the outer wall of the vent pipe 19. The safety valve 20 automatically opens to discharge gas when the gas pressure in the storage tank 1 exceeds the set value. A control panel 21 is fixedly connected to the front of the storage tank 1. The control panel 21 can centrally control the motor 10, the first solenoid valve 14, the second solenoid valve 17 and other components to realize the automated operation of the device.

[0022] In this invention, when liquid additives need to be stored, the operator first holds the sealing cap 3 and rotates it to separate the feed hopper 2 and the sealing cap 3, thus removing the sealing cap 3. An appropriate amount of liquid additive can then be injected into the storage tank 1 through the feed hopper 2. When injecting the liquid additive, the operator first presses the lifting ring 8 to lower it. The lowering of the lifting ring 8 causes the two springs 9 and the sealing block 5 to move down until the sealing block 5 is no longer in contact with the storage tank 1. During this process, the springs 9 are compressed, opening the feed hopper 2 and allowing the liquid additive to be smoothly injected into the storage tank 1. After the liquid additive is injected, the sealing cap 3 is placed on the feed hopper 2 to complete the rotational sealing of the feed hopper 2 and the sealing cap 3. The lifting ring 8 is then released; under the action of the compressed springs 9, the lifting ring 8, the two lifting rods 7, and the sealing cap 3... Block 5 moves upward until it abuts against storage tank 1, thus sealing the feed hopper 2. During liquid additive storage, motor 10 is started periodically. The output of motor 10 drives transmission rod 11 and multiple stirring wheels 12 to rotate, which can agitate the liquid additive to make it evenly mixed and prevent it from settling to the bottom. During storage, the second solenoid valve 17 is opened, and the inert gas in the inert gas high-pressure tank 15 is injected into storage tank 1 through gas delivery pipe 16. The inert gas (argon) moves to the top of storage tank 1 in the form of bubbles in the liquid additive, increasing the gas pressure in storage tank 1. Since the density of inert gas is greater than that of air, it is located below the air. The original air above storage tank 1 is discharged through vent pipe 19, so that storage tank 1 is filled with inert gas to ensure good storage effect of liquid additive.
