Description

Technical Field

[0001] This utility model belongs to the field of pesticide production technology, specifically a liquid material addition device for the production of pesticide intermediates. Background Technology

[0002] Pesticide production is the process of converting chemical and biological raw materials into pesticide products through specific processes. Pesticide production includes modules such as raw material storage and transportation, processing and testing, packaging, and waste treatment. The main products include insecticides, fungicides, herbicides, and acaricides.

[0003] Currently, the production of pesticide intermediates requires the addition of various materials. However, the current equipment for adding liquid materials cannot clean the inside of the equipment after the liquid materials are added. When other pesticide intermediates need to be produced and different materials need to be added, the residual materials can easily lead to cross-contamination, which ultimately reduces the quality of pesticide intermediates. This cannot meet the production needs of "multiple varieties and small batches" in the production of pesticide intermediates.

[0004] To address this issue, we propose a liquid feed addition device for pesticide intermediate production. Utility Model Content

[0005] The purpose of this invention is to provide a liquid material addition device for the production of pesticide intermediates, so as to solve the technical problem that the device cannot be cleaned after the material is added, and when different materials are added to produce other pesticides, cross-contamination of materials is likely to occur, which ultimately leads to a reduction in pesticide quality.

[0006] To solve the above technical problems, the technical solution of this utility model is as follows: a liquid material addition device for the production of pesticide intermediates, comprising a base plate, a storage tank, and a supporting base frame. The supporting base frame is fixedly connected to both sides of the bottom of the base plate. An installation hole is opened in the middle of the base plate. The storage tank is fixedly connected to the installation hole in the middle of the base plate. A cleaning tank and an integrated switch are also fixedly connected to the top of the base plate. A liquid pump is fixedly connected to the top of the cleaning tank. The input end of the liquid pump extends into the interior of the cleaning tank, and the output end is fixedly connected to a conveying bend pipe. The other end of the conveying bend is fixedly connected to an annular water pipe. Several nozzles are fixedly connected at intervals at the lower end of the annular water pipe. The annular water pipe is located at the top of the storage tank. The bottom of the storage tank is fixedly connected to a discharge pipe and a drain pipe. A drain valve is installed on the drain pipe. The other end of the discharge pipe is fixedly connected to a corrosion-resistant diaphragm pump. The output end of the corrosion-resistant diaphragm pump is fixedly connected to a conveying pipeline. A solenoid valve is installed on the input end of the discharge pipe. The corrosion-resistant diaphragm pump, the solenoid valve, and the liquid pump are all electrically connected to the integrated switch.

[0007] Furthermore, two connecting sections are fixedly connected at intervals to the outer surface of the annular water pipe, and the annular water pipe is fixedly connected to the inner wall of the storage tank through the connecting sections.

[0008] Furthermore, a level gauge is fixedly connected to the side of the cleaning tank.

[0009] Furthermore, a first sealing ring is fixedly connected to the input end of the corrosion-resistant diaphragm pump, the discharge pipe is fixedly connected to the input end of the corrosion-resistant diaphragm pump through the first sealing ring, a second sealing ring is fixedly connected to the output end of the corrosion-resistant diaphragm pump, and the conveying pipe is fixedly connected to the output end of the corrosion-resistant diaphragm pump through the second sealing ring 17.

[0010] Furthermore, a reinforcing frame is fixedly connected to the outer surface of the integrated switch, and the bottom surface of the reinforcing frame is fixedly connected to the upper surface of the base plate.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model, through the coordinated arrangement of a cleaning tank, a liquid pump, a conveying bend, an annular water pipe, and several nozzles, with the annular water pipe fixed to the inner wall of the storage tank, and multiple sets of nozzles, uses cleaning liquid to rinse the inside of the storage tank. This design solves the problem of existing devices where "cleaning is not possible after adding materials, and material residue remains during production changes." When different pesticides need to be produced and materials need to be changed, it can effectively remove the residual materials from the previous process in the storage tank, avoid cross-contamination between different materials, and ensure the purity and quality of subsequent pesticide products from the source, meeting the needs of "multiple varieties and small batches" in pesticide production.

[0013] 2. By setting the core conveying component as a corrosion-resistant diaphragm pump, this utility model can withstand the corrosive materials commonly found in pesticide intermediates, avoid equipment failures caused by corrosion damage to traditional pumps, significantly extend the service life of the device, and reduce equipment maintenance costs and downtime risks in pesticide production.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5The device shown is a liquid feed additive for the production of pesticide intermediates, comprising a base plate 1, a storage tank 2, and a supporting frame 4. The storage tank 2 is a cylindrical tank with an open top, and a suitable tank cover is installed at the open top. Two supporting frames 4 are provided, and the two supporting frames 4 are fixedly connected to the left and right sides of the bottom of the base plate 1. An installation hole is opened in the middle of the base plate 1, and the storage tank 2 is fixedly connected to the installation hole in the middle of the base plate 1. The outer wall of the storage tank 2 is fixedly connected to the inner wall of the installation hole on the base plate 1. A cleaning tank 3 and an integrated switch 5 are also fixedly connected to the top of the base plate 1. The cleaning tank 3 has a liquid inlet on the top and contains cleaning liquid. A liquid pump 9 is fixedly connected to the top of the cleaning tank 3. The input end of the liquid pump 9 extends into the cleaning tank 3, and the output end is fixedly connected to a conveying bend 11. The liquid pump 9 can pump the cleaning liquid in the cleaning tank 3 to the cleaning tank 3. In the conveying bend 11, an annular water pipe 8 is fixedly connected to the other end of the conveying bend 11. Several nozzles 12 are fixedly connected at intervals at the lower end of the annular water pipe 8. The output ends of all nozzles 12 are oriented obliquely downward toward the inner wall of the storage tank 2. The cleaning liquid sprayed from the nozzles 12 can contact the inner wall of the storage tank 2 to clean the remaining material adhering to the inner wall of the storage tank 2. The annular water pipe 8 is located at the top of the storage tank 2. The bottom of the storage tank 2 is fixedly connected to the unloading pipe 14 and the drain pipe 19. A drain valve 20 is installed on the drain pipe 19. A corrosion-resistant diaphragm pump 16 is fixedly connected to the other end of the unloading pipe 14. The output end of the corrosion-resistant diaphragm pump 16 is fixedly connected to the conveying pipe 18. A solenoid valve 13 is installed on the input end of the unloading pipe 14. The corrosion-resistant diaphragm pump 16, the solenoid valve 13, and the pump 9 are all electrically connected to the integrated switch 5. Integrated switch 5 includes power control switches for corrosion-resistant diaphragm pump 16, solenoid valve 13, and liquid pump 9. During normal use, drain valve 20 remains closed. When adding material, integrated switch 5 connects the circuits of solenoid valve 13 and corrosion-resistant diaphragm pump 16, activating them to transport the liquid material. When the pesticide intermediate product needs to be changed to a different batch, integrated switch 5 closes solenoid valve 13, allowing the operator to manually... Turn and open the drain valve 20, turn on the liquid pump 9 in the integrated switch 5. The liquid pump 9 starts working and pumps the cleaning liquid in the cleaning tank 3 to the conveying bend 11 and the annular water pipe 8. Finally, it sprays and washes the inner wall of the storage tank 2 through the nozzle 12. The cleaning liquid water flowing down the storage tank 2 can also wash the bottom of the storage tank 2 when it flows through the bottom of the storage tank 2. Finally, the cleaning liquid and the residual material in the storage tank 2 are discharged out of the storage tank 2 through the drain pipe 19, completing the cleaning.

[0022] To improve the stability of the connection of the annular water pipe 8, two connecting sections 10 are fixedly connected at intervals on the outer surface of the annular water pipe 8, and the annular water pipe 8 is fixedly connected to the inner wall of the storage tank 2 through the connecting sections 10.

[0023] To facilitate observation of the cleaning fluid level in the cleaning tank 3, a level gauge 7 is fixedly connected to the side of the cleaning tank 3. The level gauge 7 is a continuous level gauge.

[0024] To improve the sealing performance of the connections between the input and output ends of the corrosion-resistant diaphragm pump 16 and the various pipelines, a first sealing ring 15 is fixedly connected to the input end of the corrosion-resistant diaphragm pump 16. The discharge pipe 14 is fixedly connected to the input end of the corrosion-resistant diaphragm pump 16 via the first sealing ring 15. A second sealing ring 17 is fixedly connected to the output end of the corrosion-resistant diaphragm pump 16, and the conveying pipe 18 is fixedly connected to the output end of the corrosion-resistant diaphragm pump 16 via the second sealing ring 17. The first sealing ring 15 and the second sealing ring 17 effectively seal the connections between the input and output ends of the corrosion-resistant diaphragm pump 16 and the pipelines, enhancing the applicability of the device.

[0025] To ensure a stable connection between the integrated switch 5 and the base plate 1, a reinforcing frame 6 is fixedly connected to the outer surface of the integrated switch 5. The bottom surface of the reinforcing frame 6 is fixedly connected to the upper surface of the base plate 1. The reinforcing frame 6 strengthens the connection between the integrated switch 5 and the base plate 1, improving the stability of the connection.

[0026] The specific working process of this utility model is as follows:

[0027] In use, first open the lid of the storage tank 2, and slowly add the pesticide intermediate liquid raw material to be added into the storage tank 2. Then, open the solenoid valve 13 and start the corrosion-resistant diaphragm pump 16 via the integrated switch 5. Under the action of the corrosion-resistant diaphragm pump 16, the liquid material in the storage tank 2 passes sequentially through the discharge pipe 14, solenoid valve 13, corrosion-resistant diaphragm pump 16, and conveying pipe 18, finally being sent to the reaction vessel through the outlet of the conveying pipe 18. After the feeding is completed, close the solenoid valve 13 and the corrosion-resistant diaphragm pump 16 via the integrated switch 5. When it is necessary to change to produce different types of pesticide intermediates, ensure that the solenoid valve 13 is closed via the integrated switch 5 to prevent the cleaning fluid from flowing into the discharge pipe 14, and manually open the discharge pipe. The liquid valve 20 is used, and the liquid level gauge 7 is used to check the liquid level in the cleaning tank 3 to ensure sufficient liquid volume. The liquid pump 9 is started via the integrated switch 5. Under the operation of the liquid pump 9, the cleaning liquid in the cleaning tank 3 is drawn into the conveying bend 11 and conveyed to the annular water pipe 8 fixed to the inner wall of the storage tank 2. Several nozzles 12 at the lower end of the annular water pipe 8 spray pressurized cleaning liquid water to rinse the inner wall and bottom of the storage tank 2. After rinsing, the liquid pump 9 is turned off via the integrated switch 5, the tank cover on top of the storage tank 2 is opened, and an endoscope is used to observe whether there are any material residues on the inner wall. If there are still residues, the above cleaning steps can be repeated. After confirming that it is clean, all valves are closed to complete the production change preparation. During the cleaning process, the residual material in the storage tank 2 is carried by the cleaning liquid and discharged through the drain pipe 19 to the designated wastewater treatment system for centralized treatment.
