[0004] In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the material in the transportation process is heated by setting a zigzag air duct, the temperature of the hot air in the air duct gradually decreases due to heat exchange during use, so the problem of uneven front and back heating may occur during the heating process, resulting in low heat exchange efficiency with the material. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a pesticide intermediate material temperature regulating device to solve the problem that the temperature of the hot air in the current air duct gradually decreases due to heat exchange, which may cause uneven front and back problems during the heating process, resulting in low heat exchange efficiency with the material.

[0006] To achieve the object of the present utility model, the technical solution adopted by the present utility model is as follows: Design a temperature regulating device for pesticide intermediate materials, including a heat preservation bin, a conveying channel, a cooling water pipe and a return air duct. The conveying channel horizontally penetrates the left and right side walls of the heat preservation bin, and partition plates are fixedly connected to the upper and lower outer surfaces of the conveying channel. The bottom of the partition plate on the lower surface of the conveying channel is fixedly connected to the inner bottom of the heat preservation bin. A plurality of wind baffle plates are evenly fixedly connected to the outer surface of the conveying channel on both sides of the partition plate. An air inlet pipe and an air outlet pipe are respectively provided on the surface of one end of the heat preservation bin. The air inlet pipe and the air outlet pipe are respectively located on both sides of the partition plate, and a hot air blower is fixedly connected to the outer opening of the air inlet pipe. A return air duct is fixedly connected to the other end of the heat preservation bin. The return air duct is communicated with the inner side of the heat preservation bin, and the two openings at both ends of the heat preservation bin are respectively located on both sides of the partition plate. Electric heating pipes are vertically fixedly connected to the inner bottom of the heat preservation bin between the wind baffle plates and the inner side wall of the heat preservation bin. A cooling water pipe is fixedly connected to the inner side wall of the heat preservation bin on one side of the inner opening of the air inlet pipe.

[0007] Preferably, the wind baffle plates and the side plates are alternately distributed, and the heights of the wind baffle plates and the side plates are the same as the height of the top surface of the partition plate.

[0008] Preferably, a bin cover is movably connected to the top end of the heat preservation bin, and sealing gaskets are fixedly connected to the tops of the partition plate, the wind baffle plates and the side plates.

[0009] Preferably, a plurality of side plates are evenly fixedly connected to the front and rear inner side walls of the heat preservation bin, and the side plates and the wind baffle plates are alternately distributed.

[0010] Preferably, a heat exchanger is fixedly connected to the outer side wall of the heat preservation bin. The water outlet end of the heat exchanger is hermetically connected to a small water pump, and the water outlet end of the small water pump is communicated with one end of the cooling water pipe. The other end of the cooling water pipe is communicated with the water inlet end of the heat exchanger.

[0011] Preferably, a heat-conducting silica gel pad is fixedly connected to the outer surface of the part of the conveying channel located inside the heat preservation bin.

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

[0013] 1. By means of the hot air blower, the air inlet pipe, the air outlet pipe, the partition plate and the return air duct, the present utility model can make full use of hot air. The partition plate divides the heat preservation bin into two parts. After the hot air blower is started, hot air is blown into the inner side of the heat preservation bin through the air inlet pipe. The hot air moves inside the heat preservation bin, and then after reaching the other end of the heat preservation bin, it is guided by the return air duct, then turns back and re-enters the inner side of the heat preservation bin, and finally leaves the heat preservation bin from the air outlet pipe. Thus, the conveying channel is heated in two directions at the same time, which not only improves the utilization efficiency of hot air, reduces energy waste, but also improves the heating efficiency of the device.

[0014] 2. The utility model can adjust the temperature of the conveying channel through the wind shield, side plates, electric heating tubes and cooling water pipes. When the hot air passes through the gap between the wind shield and the inner wall of the heat preservation bin, the electric heating tubes are electrified to generate heat, which will heat the hot air and make up for the lost heat energy, so that the heating effect of the hot air on each position of the conveying channel can be maintained. And when cooling is needed, only the heating element of the hot air blower needs to be turned off, and it can be used as an ordinary exhaust fan. When exhausting, the cooling water pipe will absorb the heat in the air, so that the temperature in the heat preservation bin can be lowered, thus improving the heating and cooling effects of the device.

Detailed Embodiments

[0019] The following further describes the utility model with reference to the drawings and embodiments:

[0020] Embodiment 1: A device for adjusting the temperature of pesticide intermediate materials, see Figures 1 to 3, including a heat preservation bin 1, a conveying channel 2, a cooling water pipe 9 and a return air duct 13. The conveying channel 2 horizontally penetrates the left and right side walls of the heat preservation bin 1, and partition plates 102 are fixedly connected to the upper and lower outer surfaces of the conveying channel 2. The bottom of the partition plate 102 on the lower surface of the conveying channel 2 is fixedly connected to the inner bottom of the heat preservation bin 1. A number of wind baffle plates 11 are evenly and fixedly connected to the outer surfaces of the conveying channel 2 on both sides of the partition plate. On one end surface of the heat preservation bin 1, an air inlet duct 6 and an air outlet duct 14 are respectively provided. The air inlet duct 6 and the air outlet duct 14 are respectively located on both sides of the partition plate, and a hot air blower 5 is fixedly connected to the outer opening of the air inlet duct 6. The other end of the heat preservation bin 1 is fixedly connected to a return air duct 13, and the return air duct 13 is communicated with the inner side of the heat preservation bin 1. The two openings at both ends of the heat preservation bin 1 are respectively located on both sides of the partition plate 102. The partition plate 102 divides the heat preservation bin 1 into two parts. The hot air moves inside the heat preservation bin 1 and heats the conveying channel 2 simultaneously in two directions, which not only improves the utilization efficiency of the hot air, reduces energy waste, but also improves the heating efficiency of the device. Vertically fixedly connected to the inner bottom of the heat preservation bin 1 between the wind baffle plate 11 and the inner side wall of the heat preservation bin 1 is an electric heating tube 12. The electric heating tube 12 can adjust the temperature according to the magnitude of the energization, so as to perform supplementary heating on the hot air to different degrees. When the hot air passes through the gap between the wind baffle plate 11 and the inner side wall of the heat preservation bin 1, the electric heating tube 12 generates heat when energized and heats the hot air, compensating the lost heat energy, so that the heating effect of the hot air on each position of the conveying channel 2 can be maintained. Fixedly connected to the inner side wall of the heat preservation bin 1 on the inner opening side of the air inlet duct 6 is a cooling water pipe 9. When exhausting air, the cooling water pipe 9 absorbs the heat in the air and dissipates heat through the heat exchanger 7 in a cycle, thus facilitating the temperature adjustment.

[0021] On the parts of the conveying channel 2 located outside the two ends of the heat preservation bin 1, a feeding port 3 and a discharging port 4 are respectively provided, and a diversion trough 15 is arranged below the discharging port 4 to facilitate the discharging and guiding of materials. At the same time, a screw conveyor mechanism is installed inside the conveying channel 2, and a corresponding driving motor and a control switch are provided. The screw conveyor mechanism is a publicly known device that can be directly purchased on the market. Here, only its use is involved, and no structural and functional improvements are made to it, so it will not be described in detail here.

[0022] Specifically, referring to Figure 2 , the wind baffle plates 11 and the side plates 10 are alternately distributed, and the heights of the wind baffle plates 11 and the side plates 10 are the same as the height of the top surface of the partition plate 102. In the case of the same height, when the bin cover 101 is completely closed, the partition plate 102 will divide the inner side of the heat preservation bin 1 into two parts, and the hot air can only pass through the gap between the wind baffle plates 11 and the side plates 10, ensuring the heating effect.

[0023] Further, referring to Figure 1 and Figure 2, the top of the heat preservation bin 1 is movably connected with a bin cover 101. The tops of the partition board 102, the wind baffle 11 and the side board 10 are all fixedly connected with a sealing gasket 16. After the bin cover 101 is covered, the sealing gasket 16 will fill the gap between the bin cover 101 and the heat preservation bin 1 to prevent air leakage during the heating and ventilation process.

[0024] It should be noted that, referring to Figure 2 , a plurality of side boards 10 are evenly and fixedly connected to the front and rear inner side walls of the heat preservation bin 1, and the side boards 10 and the wind baffle 11 are alternately distributed. The side boards 10 and the wind baffle 11 set the moving path of the hot air inside the heat preservation bin 1 into a state of turning back and forth, so that the moving time of the hot air inside the heat preservation bin 1 can be increased, and the heating effect is improved.

[0025] It should be noted that, referring to Figure 2 , a heat exchanger 7 is fixedly connected to the outer side wall of the heat preservation bin 1. The water outlet end of the heat exchanger 7 is hermetically connected with a small water pump 8, and the water outlet end of the small water pump 8 is communicated with one end of a cooling water pipe 9. The other end of the cooling water pipe 9 is communicated with the water inlet end of the heat exchanger 7. The water in the cooling water pipe 9 is continuously circulated between the heat exchanger 7 and the cooling water pipe 9 driven by the small water pump 8, so as to always maintain the heat absorption effect of the cooling water pipe 9.

[0026] It should be introduced that, referring to Figure 2 , a heat-conducting silica gel pad 17 is fixedly connected to the outer surface of the part of the conveying channel 2 located inside the heat preservation bin 1. The heat-conducting silica gel pad 17 can absorb the heat energy in the hot air and conduct the heat energy to the conveying channel 2, thereby improving the heating efficiency of the hot air.

[0027] Working principle: Through the hot air blower 5, the air inlet pipe 6, the air outlet pipe 14, the partition plate 102 and the return air pipe 13, the hot air can be fully utilized. The partition plate 102 divides the heat preservation bin 1 into two parts. After the hot air blower 5 is started, hot air is blown into the inner side of the heat preservation bin 1 through the air inlet pipe 6. The hot air moves inside the heat preservation bin 1, then reaches the other end of the heat preservation bin 1 and is guided by the return air pipe 13, then turns back and re-enters the inner side of the heat preservation bin 1, and finally leaves the heat preservation bin 1 from the air outlet pipe 14, so as to heat the conveying channel 2 in two directions at the same time. This not only improves the utilization efficiency of the hot air, reduces energy waste, but also improves the heating efficiency of the device. At the same time, through the wind baffle 11, the side plate 10, the electric heating tube 12 and the cooling water pipe 9, the temperature of the conveying channel 2 can be adjusted. During the movement inside the heat preservation bin 1, it will constantly move forward in a zigzag manner due to the obstruction of the wind baffle 11 and the side plate 10, so that the stay time of the hot air inside the heat preservation bin 1 is greatly increased. And when passing through the gap between the wind baffle 11 and the inner wall of the heat preservation bin 1, the electric heating tube 12 is energized to generate heat to heat the hot air and make up for the lost heat energy, so that the heating effect of each position of the conveying channel 2 by the hot air can be maintained. And when cooling is needed, only the heating element of the hot air blower 5 needs to be turned off, and it can be used as an ordinary exhaust fan. When exhausting air, the cooling water pipe 9 will absorb the heat in the air and the heat exchanger 7 will carry out circulating heat dissipation, so that the temperature inside the heat preservation bin 1 can be lowered, thus improving the heating and cooling effects of the device.
