Description

Technical Field

[0001] This utility model relates to the field of production technology for the preparation of deodorizing disinfectant powder, and specifically to a heat exchange device for the preparation of deodorizing disinfectant powder. Background Technology

[0002] Disinfectants are very common items in daily life and production. People usually use disinfectants to wash items. Disinfectants are preparations that kill pathogenic microorganisms on transmission media and make them harmless. They are different from antibiotics. Their main role in disease prevention is to eliminate pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases. People often refer to disinfectants as "chemical disinfectants".

[0003] The production process of deodorizing disinfectant powder involves several different steps. Because each step involves different chemical reactions, multiple different reaction temperatures are required, and these temperatures must be maintained. The reaction temperatures are generally between 20℃ and 200℃. In existing technologies, a single heat exchanger can only provide one temperature, and the temperature control is imprecise, resulting in poor heat transfer efficiency.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a heat exchange device for preparing deodorizing disinfectant powder, which can simultaneously output multiple cold fluids at different temperatures, and the temperature of the output cold fluids can be precisely set as needed; the heat exchanger has higher heat exchange efficiency and better heat exchange effect.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A heat exchange device for preparing deodorizing disinfectant powder includes a heating box and a heat exchange box. The heat exchange box has multiple cavities, and each cavity is equipped with a heat exchanger. The heat exchanger includes a heat exchange main pipe, and U-shaped tubes are evenly arranged around the heat exchange main pipe. Both ends of the U-shaped tubes are connected to the heat exchange main pipe. The heat exchange main tube is equipped with a flow-limiting cylinder that is slidably connected to its inner wall. One end of the flow-limiting cylinder is open and is engaged with one end of a U-shaped tube. The center of the other end of the flow-limiting cylinder is hinged to one end of a connecting rod. The other end of the connecting rod is eccentrically hinged to a drive wheel. The drive wheel is fixed to the shaft of a motor. A motor cover is fixed to the outer wall of the heat exchange main tube, and the motor is inside the motor cover.

[0007] In one optimized solution, the flow-limiting cylinder has multiple through holes evenly distributed around one end near the connecting rod, and a valve plate is hinged to the outside of each through hole. A torsion spring is provided at the hinge point between the valve plate and the flow-limiting cylinder.

[0008] Furthermore, a support tube is fixed inside the heat exchange box, and the heat exchanger support tubes are arranged at intervals. The two ends of the heat exchange main tube are fixedly connected to the support tubes, and the heat exchange main tube and the support tubes form a straight channel inside the heat exchange box.

[0009] Furthermore, each cavity of the heat exchanger is equipped with a temperature sensor, and each cavity has an oil inlet and an oil outlet arranged alternately on both sides.

[0010] Furthermore, multiple oil rings are provided on the side wall of the flow restrictor near the connecting rod end.

[0011] Furthermore, the outlet of the support pipe is connected to the inlet of the heating box via a return oil pipe, and the inlet of the support pipe is connected to the outlet of the heating box via an oil inlet pipe. An oil pump is installed on the oil inlet pipe.

[0012] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: 1. The temperature sensor feeds back the temperature signal to the controller, which controls the movement of the flow-limiting cylinder via the motor to switch the flow path of the hot fluid, thus keeping the cold fluid in the cavity within the set temperature range. Different cavities can be set with different temperatures to achieve simultaneous output of cold fluid at different temperatures.

[0013] 2. The multiple U-shaped tubes evenly distributed on the main heat exchange pipe make the heat exchange efficiency higher and the heat exchange effect better.

Detailed Implementation

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0018] like Figures 1-6 As shown in the figure, this utility model provides a heat exchange device for preparing deodorizing disinfectant powder, including a heating box 6 and a heat exchange box 1. The heat exchange box 1 contains multiple cavities, each housing a heat exchanger 2 and a temperature sensor 4. Each cavity has an oil inlet 101 and an oil outlet 102 arranged alternately on both sides. A support pipe 3 is fixed inside the heat exchange box 1, with the heat exchanger 2 and support pipe 3 arranged at intervals. The heat exchange main pipe 202 has openings at both ends and is fixedly connected to the support pipe 3, forming a straight channel within the heat exchange box 1.

[0019] U-shaped tubes 201 are evenly arranged around the heat exchange main pipe 202, and both ends of the U-shaped tubes 201 are connected to the heat exchange main pipe 202.

[0020] The heat exchange main pipe 202 is internally provided with a flow-limiting cylinder 206 slidably connected to its inner wall; one end of the flow-limiting cylinder 206 is open, and the other end of the flow-limiting cylinder 206 is provided with multiple circumferentially distributed through holes 2061. A valve plate 208 is hinged to the outside of each through hole 2061, and a torsion spring is provided at the hinge point between the valve plate 208 and the flow-limiting cylinder 206. Multiple oil rings 2062 are provided on the side wall of the end of the flow-limiting cylinder 206 near the connecting rod 205.

[0021] The open end of the flow-limiting cylinder 206 is engaged with one end of the U-shaped tube 201. The center of the other end of the flow-limiting cylinder 206 is hinged to one end of the connecting rod 205. The other end of the connecting rod 205 is eccentrically hinged to the drive wheel 204. The drive wheel 204 is fixed to the rotating shaft of the motor 203. The outer wall of the heat exchange main tube 202 is fixed with a motor cover 207, and the motor 203 is inside the motor cover 207.

[0022] A temperature sensor 4 is installed inside the heat exchange box 1.

[0023] The outlet of the support pipe 3 is connected to the inlet of the heating box 6 through the return oil pipe 8, and the heating box 6 is equipped with a heating pipe 7.

[0024] The inlet of the support pipe 3 is connected to the oil outlet of the heating box 6 through the oil inlet pipe 9, and an oil pump 5 is installed on the oil inlet pipe 9.

[0025] The working principle of this utility model: The hot fluid, heated in the heating chamber 6, is pumped by the oil pump 5 to the radiator 2 in the first cavity. The temperature sensor 4 transmits the temperature signal to the controller in real time. When the temperature of the cold fluid in the heat exchange chamber 1 is lower than the set temperature, the controller controls the motor 203 to drive the drive wheel 204 to rotate, causing the connecting rod eccentrically hinged to the drive wheel 204 to move the flow-limiting cylinder 206, so that both ends of the U-shaped tube 201 are connected to the heat exchange main pipe 202. Under the action of the torsion spring, the valve plate 208 tightly engages with the through hole 2061 on the flow-limiting cylinder 206. At this time, the heat exchange main pipe 202 cannot flow, and the hot fluid flows to one end of the heat exchange main pipe 202, then flows into one end of the U-shaped tube 201, and returns to the heat exchange main pipe 202 from the other end of the U-shaped tube 201. The hot fluid exchanges heat efficiently with the cold fluid in the first cavity through multiple U-shaped tubes 201, so that the cold fluid is in a heated state.

[0026] When the temperature in the first chamber rises to the preset temperature, under the control of the controller, the flow-limiting cylinder 206 moves in the opposite direction, blocking one end of the U-shaped tube 201. At this point, the U-shaped tube 201 cannot flow, and under pressure, the hot fluid pushes the valve plate 208 open, allowing the hot fluid to flow directly from one end of the heat exchange main pipe 202 to the other. The cold fluid and hot fluid exchange heat only through the heat exchange main pipe 202, keeping the cold fluid in the first chamber in a temperature-maintaining state. When the temperature of the cold fluid falls below the set temperature, the controller will again control the flow-limiting cylinder 206 to move, switching back to the heating state, thus keeping the cold fluid in the chamber within the set temperature range.

[0027] The cold fluid flows out from the oil outlet 102 of the heat exchanger to heat the corresponding production process, and then flows back to the heat exchanger 1 through the oil inlet 101 of the heat exchanger.

[0028] The hot fluid flows out of the first chamber and then into the next chamber. The working principle of the next chamber is exactly the same as that of the first chamber, except that the set temperature is different. After flowing out of the last chamber, it flows back to the heating box 6 through the return oil pipe 8 for heating.
