Description

Technical Field

[0001] This utility model belongs to the field of pesticide production technology, specifically relating to a pesticide concentration device for pesticide production. Background Technology

[0002] Pesticides are chemical agents used in agriculture to control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry, and animal husbandry production, environmental and household sanitation for pest control and disease prevention, and industrial applications for mold and insect prevention. Concentration refers to increasing the concentration of a solution by evaporating a solvent; generally, it means reducing the unwanted portion while increasing the relative content of the desired portion. Concentration devices are frequently used in pesticide production for this process.

[0003] The existing Chinese patent with publication number CN219848169U discloses a pesticide formulation concentration device, including a pesticide filling tank and a water bath heating device. The heating tank is installed in the water bath heating device. The water bath heating device includes a water tank, two sets of electric heating tubes are arranged in the water tank, multiple sets of first support columns are arranged at the bottom of the water tank, multiple sets of second support columns are arranged on the inner side wall of the water tank, the bottom of the pesticide filling tank is attached to the top of the multiple sets of first support columns, and the water tank is slidably attached to the inner end of the multiple sets of second support columns.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: during the water bath heating process, only the side wall of the pesticide container is in contact with the hot water, resulting in the pesticide in the central area of ​​the container being heated at a lower temperature than the pesticide in the surrounding area. This leads to slower heat transfer to the central area, uneven heating of the pesticide, and reduced concentration efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pesticide concentration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pesticide concentration device, comprising a concentration tank, a hot water tank, and a hot water circulation structure. The concentration tank is externally fixedly connected to a casing. The hot water circulation structure includes a water pump connected to one side of the hot water tank. An inlet pipe is connected between the outlet end of the water pump and the casing. A conduit communicating with the interior of the casing is fixedly connected to one side of the concentration tank. A guide sleeve is fixedly connected to one end of the conduit. A first hollow tube is rotatably connected inside the guide sleeve. The first hollow tube is rotatably installed at the center of the concentration tank. A through hole is opened on the surface of the first hollow tube inside the guide sleeve. A plurality of second hollow tubes are fixedly connected to the surface of the first hollow tube. The lower end of the first hollow tube extends through to the bottom of the casing and is rotatably connected to a return water pipe, which is connected to the hot water tank.

[0007] In a preferred embodiment, a feed pipe is provided on one side of the top of the concentration tank, and a discharge pipe is provided on one side of the bottom of the concentration tank.

[0008] In a preferred embodiment, a motor is fixedly installed at the center of the top of the concentration tank, and the output end of the motor is fixedly connected to the upper end of the first hollow tube.

[0009] In a preferred embodiment, the first hollow tube is rotatably connected to the concentration tank and the casing via a first sealed bearing.

[0010] In a preferred embodiment, the first hollow tube is rotatably connected to the guide sleeve via a second sealed bearing.

[0011] In a preferred embodiment, a rotary joint is provided between the first hollow pipe and the return water pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This pesticide concentration device features a hot water circulation structure. During concentration, a water pump is activated to deliver hot water from the hot water tank to the casing via an inlet pipe. Once the casing is full, the hot water flows along a guide tube into a guide sleeve. The hot water then passes through a through-hole into a first hollow tube, flows into a second hollow tube, and finally returns to the hot water tank via a return pipe, completing the circulation. The hot water in the casing heats the pesticides around the center of the concentration tank, while the hot water in the first and second hollow tubes heats the pesticides in the central area of ​​the tank, accelerating heat transfer, ensuring even heating of the pesticides, and improving concentration efficiency.

[0014] This pesticide concentration device, equipped with a motor, can be activated during concentration to drive the first hollow tube to rotate, which in turn drives the second hollow tube to stir the pesticide, ensuring that the pesticide is heated more evenly. Attached Figure Description

[0026] The working principle and usage process of this utility model are as follows: First, during concentration, the water pump 31 can be started to transport the hot water in the hot water tank 2 to the casing 11 through the inlet pipe 32. When the casing 11 is full of hot water, the hot water in the casing 11 will enter the guide sleeve 34 along the guide pipe 33. The hot water entering the guide sleeve 34 will then enter the first hollow tube 35 through the through hole 36, flow into the second hollow tube 37 through the first hollow tube 35, and finally return to the hot water tank 2 through the return pipe 38 to complete the circulation. The hot water in the casing 11 can heat the pesticides around the concentration tank 1, and the hot water in the first hollow tube 35 and the second hollow tube 37 can heat the pesticides in the central area of ​​the concentration tank 1, accelerating the heat transfer. At the same time, the motor 14 can be started to drive the first hollow tube 35 to rotate, so that the first hollow tube 35 drives the second hollow tube 37 to stir the pesticides, so as to make the pesticides heat evenly and improve the concentration efficiency.
