Description

Technical Field

[0001] The utility model relates to the field of pesticide production system equipment, in particular to a gas system used in SC suspension production. Background Art

[0002] SC aqueous suspension, pesticide SC suspension is a pesticide preparation in which insoluble or slightly soluble solid pesticide original is dispersed in water, and its international code is SC. SC has a high fire safety factor, is not flammable or explosive, has a small particle size, has high biological activity for target organisms, and is safer and more environmentally friendly than other existing pesticide formulations. Therefore, SC suspension has become a pesticide variety with a larger production scale among new water-based pesticide formulations.

[0003] SC suspension is also called suspension, concentrated suspension, water suspension or flowable agent. The water-insoluble solid pesticide is ground with additives in a sand mill and dispersed in a water medium to form a suspension. In this way, the solid original medicine that is insoluble or slightly soluble in water can be evenly dispersed in water to form a liquid-solid system with tiny particles and high suspension. Therefore, the solid pulverization of pesticides is an important production step of SC suspension, but when the solid pesticide particles are output through the outlet section of the sand mill, blockage is often encountered.

[0004] In the production process of SC suspension, especially in the mixing process, solid pesticides tend to settle, clump, and aggregate. The materials can easily block the discharge pipe at the bottom of the mixing tank and need to be cleared manually. In this case, the workers need to face environmental hazards and the production process needs to be suspended for a period of time, resulting in low production efficiency. Summary of the invention

[0005] Aiming at the problem that the outlet section of the above sand mill is easy to be blocked, and the SC suspension mixing tank settles, agglomerates, and blocks the feed pipe of the mixing tank during the mixing process, the utility model provides a gas system for SC suspension production, including:

[0006] A feeding pipe, wherein the feeding pipe is provided with a first outlet valve, one end of the feeding pipe is connected to the mixing tank, and the other end is connected to the U-shaped pipe and the recovery pipe, the recovery pipe is provided with a second outlet valve, the other end of the U-shaped pipe is connected to the recoil pipe, and then connected to the output pipe, the output pipe is provided with a third outlet valve,

[0007] In the first state, the first outlet valve remains open, the second outlet valve and the third outlet valve are closed, and the recoil pipe outputs gas to the U-shaped tube so that the blocked material in the feed pipe is recoiled to the mixing tank.

[0008] In some embodiments, one end of the recoil pipe is connected to the U-shaped pipe, and the other end is also connected to the pressure-stabilizing tank. A recoil valve and a check valve are provided on the recoil pipeline.

[0009] In some embodiments, the pressure stabilizing tank is also connected to a protective gas pipe, the other end of which is connected to a mixing tank, and the protective gas pipe is used to transport inert gas to the mixing tank to isolate the material in the mixing tank from the air.

[0010] In some embodiments, the pressure stabilizing tank is also connected to a dredging air pipe, the other end of which is connected to the sand mill outlet pipe, and the dredging air pipe is used to transport gas to the sand mill outlet pipe to clear the blockage in the sand mill outlet pipe.

[0011] In some embodiments, the U-shaped tube is further provided with a filter plate, and the filter plate is used to filter particles larger than a preset value flowing through the U-shaped tube, and the particles larger than the preset value remain in the U-shaped tube.

[0012] In some embodiments, the filter includes an upper part, a lower part and a filter plate, the filter plate has a screen with a predetermined mesh number, the upper part and the lower part are fastened together by a bolt connection pair, and the filter plate is fixed between the upper part and the lower part.

[0013] In some embodiments, the recovery pipe is connected to a recovery tank. In the second state, the first outlet valve and the second outlet valve are closed, the second outlet valve is opened, the recoil pipe outputs gas to the U-shaped tube, and particles in the U-shaped tube larger than a preset value enter the recovery tank.

[0014] In some embodiments, the recovery tank is connected to a sand mill, and the particles larger than a preset value are processed by the sand mill and then recovered.

[0015] In some embodiments, the gas is nitrogen or argon.

[0016] The advantages of the utility model are:

[0017] 1. The utility model uses a recoil pipe to dredge the feed pipe through the switches of the first outlet valve, the second outlet valve and the third outlet valve, thereby avoiding the traditional manual disassembly operation, reducing the workers' contact with materials, reducing labor intensity, and maintaining the health of production personnel. When the temperature of the mixing tank is too high or when producing some materials that are easy to clump, settle and agglomerate, the user can quickly eliminate the blockage of the feed pipe, thereby increasing the production efficiency.

[0018] 2. In some optional embodiments, by setting up a U-shaped tube and a filter, materials with excessively large particle diameters in the pipeline are intercepted to improve the quality of products in subsequent work stages. The U-shaped tube collects larger particles, and through the backflush tube and the switches of the first outlet valve, the second outlet valve, and the third outlet valve, the larger particles are collected into a recovery tank for later recovery and grinding.

[0019] 3. In some optional implementation schemes, the pressure stabilizing tank is connected to the mixing tank through a protective gas pipe, and the pressure stabilizing tank delivers protective gas to the mixing tank to protect the materials in the mixing tank.

[0036] The pressure-stabilizing tank 4 is used to store gas. The gas pressurizes the pressure-stabilizing tank 4 from the G direction and maintains a certain pressure. When the recoil valve 411 is opened, the gas rushes into the U-tube 12 through the recoil pipe 41, and then clears the discharge pipe 11 section.

The sand mill outlet pipe 62 is close to the sand mill 6 and is provided with a sand mill outlet valve 65. When the sand mill outlet pipe 62 encounters abnormal conditions such as blockage, the sand mill outlet valve 65 is closed, and the dredging valve 431 is opened, and the dredging air pipe 43 transports gas to the sand mill outlet pipe 62, and the output direction is as shown in G1 to flush out the blockage in the sand mill outlet pipe 62.

[0044] When the user does not perform processing and recycling operations, the raw material pipe 64 transports the raw material from direction I to the sand mill 6 for grinding.
