Abstract
Description
Technical Field
[0001] This utility model relates to the field of herbicide production technology, and in particular to a temperature-controlled feeding device for herbicide production. Background Technology
[0002] Herbicides are pesticides that cause weeds to die completely or selectively, eliminating or inhibiting plant growth. Current herbicide development focuses on high-efficiency, low-toxicity, broad-spectrum, and low-dosage varieties, with single-use herbicides that minimize environmental pollution becoming mainstream. Herbicide production involves mixing different raw materials. Temperature control during mixing is a crucial factor affecting product quality. However, when different raw materials are added in different orders, the temperature fluctuates significantly. For example, materials added earlier often have lower temperatures, leading to a decrease in the mixing tank temperature and impacting product quality. Therefore, a temperature-controlled feeding device is needed to preheat the raw materials before injecting them into the mixing tank. However, current temperature-controlled feeding devices often preheat the stored raw materials to the same temperature as the mixing tank before injecting them into the mixing device. This method is slow, wastes heating energy when there is residual raw material, and can easily cause the raw materials to deteriorate, making them unusable. Utility Model Content
[0003] To overcome the technical defects of the existing technology, this utility model provides a temperature-controlled feeding device for herbicide production, which can quickly adjust the temperature of herbicide raw materials and control the temperature locally according to the feeding amount, without the need for overall heating, thus improving the feeding effect.
[0004] The technical solution adopted by this utility model is: a temperature-controlled feeding device for herbicide production, including a storage box, a connecting pipe fixedly installed at the lower end of the storage box, a temperature control box fixedly installed at the other end of the connecting pipe, and an inlet pipe and an outlet pipe fixedly installed at both ends of the upper surface of the temperature control box, respectively. A flow control valve is fixedly installed on the connecting pipe, and a feeding pipe is fixedly installed at the other end of the temperature control box. The feeding pipe is connected to the feeding end of an external mixing device. Square heat exchange tubes are fixedly installed in an array inside the temperature control box. The material inside the connecting pipe enters the feeding pipe through the heat exchange tubes. First, the external liquid carrying heat is injected into the temperature control box through the inlet pipe and discharged through the outlet pipe, forming a circulation. The raw material is then injected into the storage tank for storage. When it is necessary to inject raw material into the external herbicide mixing tank, the raw material in the storage tank is quantitatively injected into the temperature control box through the flow control valve. As it passes through the heat exchange tube, the raw material is heated and its temperature is controlled so that the raw material is at the same temperature as the inside of the external mixing tank. Then, it enters the external mixing tank through the feed pipe, reducing temperature fluctuations inside the mixing tank during feeding and improving the quality of herbicide production.
[0005] Preferably, the lower end of the storage box is fixedly equipped with support legs in a circumferential array, and the outside of the temperature control box is covered with heat insulation cotton. The support legs improve the stability of the storage box and the heat insulation cotton reduces the heat loss of the circulating hot solution and avoids energy waste.
[0006] Preferably, partitions are fixedly installed at both ends of the temperature control box, and the heat exchange tube is located between the partitions. The partitions facilitate the entry of raw materials into the heat exchange tube and isolate the raw materials from the external heating solution to avoid mixing.
[0007] Preferably, the interior of the temperature control box is divided into an inlet chamber and an outlet chamber by the partition. The connecting pipe is connected to the inlet chamber, and the feeding pipe is connected to the outlet chamber. Through the inlet chamber and the outlet chamber, the raw material can enter the interior of multiple heat exchange tubes at the same time, thereby increasing the contact area with the heat source solution and improving the heat exchange efficiency.
[0008] Preferably, both ends of the heat exchange tube are connected to the inlet chamber and the outlet chamber respectively, and the inlet tube and the outlet tube are connected to the space formed between the partition plate, so as to facilitate the heat exchange between the temperature-controlled solution and the raw material through the heat exchange tube to control the temperature of the raw material.
[0009] Preferably, an upper baffle is fixedly installed in an array at the upper part of the temperature control box, and a lower baffle is fixedly installed in an array at the lower part of the temperature control box. The upper baffle and the lower baffle are alternately distributed, thereby improving the heat exchange effect of the heat source solution on the raw material.
[0010] Preferably, the upper baffle and the lower baffle are distributed between the liquid inlet pipe and the liquid outlet pipe, and the channel formed by the upper baffle and the lower baffle is in a serpentine state, so that the heat source solution flows along the serpentine channel, increasing the contact effect with the heat exchange tube.
[0011] Preferably, the inlet pipe is positioned closer to the feed pipe, and the outlet pipe is positioned closer to the connecting pipe, so that the flow direction of the heat source solution is opposite to that of the raw material.
[0012] The beneficial effects of this utility model are: by using a temperature control box and heat exchange tube, it is convenient to exchange heat and control the temperature of the raw materials entering the external mixing tank. The upper and lower baffles increase the formation of heat source flow, improve the accuracy of temperature control, and eliminate the need to adjust the temperature of the herbicide raw materials to the same temperature inside the mixing tank. Only the temperature of the raw materials entering the mixing tank needs to be controlled, which reduces energy consumption, avoids raw material waste, and facilitates use.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] like Figures 1-5As shown, this embodiment provides a temperature-controlled feeding device for herbicide production, including a storage tank 1. A connecting pipe 2 is fixedly installed at the lower end of the storage tank 1, and a temperature control box 3 is fixedly installed at the other end of the connecting pipe 2. An inlet pipe 4 and an outlet pipe 5 are fixedly installed at both ends of the upper surface of the temperature control box 3, respectively. A flow control valve 6 is fixedly installed on the connecting pipe 2. A feeding pipe 7 is fixedly installed at the other end of the temperature control box 3, and the feeding pipe 7 is connected to the feeding end of an external mixing device. Square heat exchange tubes 8 are fixedly installed in an array inside the temperature control box 3. The material inside the connecting pipe 2 enters the feeding pipe 7 through the heat exchange tubes 8. In use, the external liquid carrying heat is first injected into the interior of the temperature control box 3 through the inlet pipe 4, and... The liquid is discharged through the outlet pipe 5, forming a circulation. The external liquid can be water or oil. The raw material is injected into the storage tank 1 for storage. When it is necessary to inject the raw material into the external herbicide mixing tank, the flow control valve 6 injects the raw material in the storage tank 1 into the temperature control box 3 in a metered manner. When passing through the heat exchange pipe 8, the raw material is heated and its temperature is controlled so that the raw material is at the same temperature as the inside of the external mixing tank. Then, it enters the external mixing tank through the feed pipe 7, which reduces the temperature fluctuation inside the mixing tank during feeding, improves the quality of herbicide production, facilitates use, and eliminates the need for overall temperature adjustment of the raw material inside the storage tank 1. Only local temperature adjustment of the raw material supplied into the mixing tank is required, which reduces energy consumption.
[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 1 As shown, the lower end of the storage box 1 is fixedly equipped with support legs 9 in a circular array, and the outside of the temperature control box 3 is covered with heat insulation cotton 10. The support legs 9 improve the stability of the storage box 1. The lower end of the storage box 1 has a funnel-shaped structure, which facilitates the outflow of raw materials. The heat insulation cotton 10 reduces the heat loss of the circulating hot solution and avoids energy waste.
[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, partitions 11 are fixedly installed at both ends of the temperature control box 3. The heat exchange tubes 8 are located between the partitions 11. The partitions 11 facilitate the entry of raw materials into the heat exchange tubes 8 and isolate the raw materials from the external heating solution to avoid mixing, thus facilitating heat exchange and temperature control. The partitions 11 form an inlet chamber 12 and an outlet chamber 13 at both ends of the temperature control box 3. The connecting pipe 2 is connected to the inlet chamber 12, and the feed pipe 7 is connected to the outlet chamber 13. The inlet chamber 12 and the outlet chamber 13 facilitate the simultaneous entry of raw materials into the interior of multiple heat exchange tubes 8, increasing the contact area with the heat source solution, improving the heat exchange effect, and increasing the heat exchange efficiency. Both ends of the heat exchange tubes 8 are connected to the inlet chamber 12 and the outlet chamber 13, respectively. The inlet pipe 4 and the outlet pipe 5 are connected to the space formed between the partitions 11, facilitating the heat exchange between the temperature control solution and the raw materials through the heat exchange tubes 8, thereby controlling the temperature of the raw materials.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5 As shown, upper baffles 14 are fixedly installed in an array at the upper part of the temperature control box 3, and lower baffles 15 are fixedly installed in an array at the lower part of the temperature control box 3. The upper baffles 14 and lower baffles 15 are alternately distributed. Through the upper baffles 14 and lower baffles 15, the flow path of the heat source solution inside the temperature control box 3 is increased, thereby improving the heat exchange effect of the heat source solution on the raw material. The upper baffles 14 and lower baffles 15 are distributed between the inlet pipe 4 and the outlet pipe 5. The channel formed by the upper baffles 14 and lower baffles 15 is in a serpentine state, which allows the heat source solution to flow along the serpentine channel, increasing the contact effect with the heat exchange tube 8, and thus facilitating heat exchange and temperature control of the raw material inside the heat exchange tube 8. The inlet pipe 4 is close to the feed pipe 7, and the outlet pipe 5 is close to the connecting pipe 2, so that the flow direction of the heat source solution and the raw material is opposite, improving the full utilization of heat during heat exchange.
