Description

Technical Field

[0001] This utility model belongs to the field of waste gas collection and treatment technology, and in particular relates to a control device for waste gas collection area of ​​chemical storage tanks. Background Technology

[0002] According to the published patent CN222196420U, a waste gas condensation treatment device based on a chemical tank area includes: a shell, a cooling cylinder fixedly installed inside the shell, and a worm gear tube disposed inside the cooling cylinder. One end of the worm gear tube is fixedly connected to an inlet pipe, and the other end of the worm gear tube is connected to an outlet pipe. A first spring and a second spring can drive a sealing plate to reset, sealing the gas delivery pipe and preventing gas inside the inlet pipe from entering the gas delivery pipe. However, it still has the following shortcomings:

[0003] The above-mentioned equipment can cool the waste gas generated by the reaction to a certain extent during use. However, during the process of exhausting the waste gas, the waste gas may flow back, causing the waste gas to re-enter the reaction tank, resulting in an increase in the gas pressure inside the reaction tank and potentially leading to dangerous situations such as explosion. Furthermore, the above-mentioned equipment is not convenient to control the exhaust rate of the device according to the actual needs of the user. Therefore, we propose a chemical storage tank waste gas collection area control device. Summary of the Invention

[0004] The purpose of this utility model is to provide a chemical storage tank exhaust gas collection area control device. Through a heat dissipation mechanism and a control mechanism, it solves the problem that existing equipment can cool the exhaust gas generated by the reaction to a certain extent, but during the exhaust gas discharge process, the exhaust gas may backflow, causing the exhaust gas to re-enter the reaction tank, resulting in increased gas pressure inside the reaction tank and dangerous situations such as explosion. In addition, existing equipment is not convenient to control the exhaust rate of the device according to the actual needs of the user.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a chemical storage tank exhaust gas collection area control device, including a chemical tank, an exhaust pipe fixedly connected to the outer wall of the chemical tank, a material inlet fixedly connected to the top outer wall of the end of the chemical tank near the exhaust pipe, and a heat dissipation mechanism provided on the outer wall of the exhaust pipe.

[0007] The heat dissipation mechanism includes a heat dissipation box, the outer wall of which is fixedly connected to the outer wall of the exhaust pipe. A heat-conducting fin is fixedly connected to the inner wall of the heat dissipation box. A motor is fixedly connected to the inner wall of the heat dissipation box at the end away from the heat-conducting fin. A drive shaft is fixedly connected to the bottom output end of the motor via a coupling. A fan blade is fixedly connected to the outer wall of the drive shaft. A brush plate is fixedly connected to the outer wall of the drive shaft at the end away from the fan blade. A dustproof plate is fixedly connected to the inner wall of the heat dissipation box at the end near the brush plate.

[0008] Furthermore, a fixing plate is fixedly connected to the inner wall of the exhaust pipe, and a sealing gasket is fixedly connected to the outer wall of the fixing plate near the heat sink.

[0009] Furthermore, a spring is fixedly connected to the outer wall of the fixing plate, and the outer wall of the spring is fixedly connected to the inner wall of the exhaust pipe. A control mechanism is provided on the outer wall of the heat dissipation box.

[0010] Furthermore, the control mechanism includes a connecting pipe, the outer wall of which is fixedly connected to the outer wall of the heat sink, and a mounting plate is fixedly connected to the outer wall of the end of the connecting pipe away from the heat sink.

[0011] Furthermore, the inner wall of the mounting plate is provided with a plurality of annular grooves, and a plurality of sliders are slidably connected to the inner wall of the annular grooves.

[0012] Furthermore, a baffle is fixedly connected to the outer wall of each of the sliders, and a fixed shaft is fixedly connected to the outer wall of the baffle at the end away from the slider.

[0013] Furthermore, the inner wall of the mounting plate is rotatably connected to a second mounting plate, and the inner wall of the second mounting plate near the fixed shaft is provided with a plurality of arc-shaped grooves, the inner wall of the arc-shaped grooves being slidably connected to the outer wall of the fixed shaft.

[0014] Furthermore, a worm gear is fixedly connected to the outer wall of the second mounting plate, and a worm is rotatably connected to the outer wall of the mounting plate near the worm gear, the outer wall of the worm meshing with the outer wall of the worm gear.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a spring on a fixed plate. When the equipment is needed, the materials to be chemically reacted are fed into the chemical tank through the inlet. An external waste gas collection device is installed on the connecting pipe of the mounting plate. Waste gas is generated during the reaction and is discharged from the exhaust pipe. During the discharge process, the waste gas passes through the fixed plate and squeezes the sealing gasket and continuously compresses the spring, causing the sealing gasket to gradually detach from the inner wall of the exhaust pipe. This achieves a certain degree of heat dissipation for the waste gas during discharge and prevents the waste gas from flowing back into the chemical tank and causing an increase in the gas pressure inside the chemical tank.

[0017] 2. This utility model incorporates a baffle on the slider. When the user needs to control the flow rate of exhaust gas in the connecting pipe, rotating the worm gear causes the worm wheel to rotate, which in turn causes the mounting plate two to rotate. The rotation of the mounting plate two, through the arc groove, causes the fixed shaft to move linearly along the trajectory of the arc groove. Because the annular groove limits the movement trajectory of the slider, and the slider, baffle, and fixed shaft are fixedly connected, the user can freely control the exhaust rate of the exhaust pipe according to the actual exhaust gas volume. This avoids the risk of gas accumulation or explosion due to excessively rapid discharge, thus improving the safety of on-site operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a chemical storage tank exhaust gas collection area control device, including a chemical tank 1. An exhaust pipe 101 is fixedly connected to the outer wall of the chemical tank 1. An injection port 102 is fixedly connected to the top outer wall of the end of the chemical tank 1 near the exhaust pipe 101. A heat dissipation mechanism 2 is provided on the outer wall of the exhaust pipe 101. Through the injection port 102, it is convenient for the user to inject the material to be reacted into the chemical tank 1. At the same time, the injection port 102 can seal the chemical tank 1.

[0029] The heat dissipation mechanism 2 includes a heat dissipation box 201. The outer wall of the heat dissipation box 201 is fixedly connected to the outer wall of the exhaust pipe 101. A heat-conducting plate 202 is fixedly connected to the inner wall of the heat dissipation box 201. A motor 203 is fixedly connected to the inner wall of the end of the heat dissipation box 201 away from the heat-conducting plate 202. The heat-conducting plate 202 can divide the heat dissipation box 201 into upper and lower layers. At the same time, the heat-conducting plate 202 can seal the heat dissipation box 201 to prevent the exhaust gas in the upper layer from directly entering the lower layer. The heat-conducting plate 202 can also transfer heat from the exhaust gas. In the lower layer of the heat sink 201, the bottom output end of the motor 203 is fixedly connected to the drive shaft 204 via a coupling. The outer wall of the drive shaft 204 is fixedly connected to the fan blade 205. The outer wall of the drive shaft 204 away from the fan blade 205 is fixedly connected to the brush plate 206. The inner wall of the heat sink 201 near the brush plate 206 is fixedly connected to the dustproof plate 207. The dustproof plate 207 can prevent external dust and other impurities from entering the heat sink 201, causing the fan blade 205 to come into contact with stones or other impurities, resulting in entanglement or even damage.

[0030] A fixing plate 208 is fixedly connected to the inner wall of the exhaust pipe 101. A sealing gasket 209 is fixedly connected to the outer wall of the fixing plate 208 near the heat sink 201. A spring 210 is fixedly connected to the outer wall of the fixing plate 208. The outer wall of the spring 210 is fixedly connected to the inner wall of the exhaust pipe 101. The spring 210 can use its own elastic force to always keep the sealing gasket 209 tightly against the inner wall of the exhaust pipe 101, so that when the exhaust pipe 101 stops exhausting, it can always keep the exhaust pipe 101 sealed. The heat sink 201 is sealed, and a control mechanism 3 is provided on the outer wall. The control mechanism 3 includes a connecting pipe 301. The outer wall of the connecting pipe 301 is fixedly connected to the outer wall of the heat sink 201. An installation plate 302 is fixedly connected to the outer wall of the end of the connecting pipe 301 away from the heat sink 201. Several annular grooves 303 are provided on the inner wall of the installation plate 302. The annular grooves 303 can limit the movement trajectory of the slider 304, so that it can only move in a straight line along the direction of the annular grooves 303 within the annular grooves 303.

[0031] The inner wall of the annular groove 303 is slidably connected to several sliders 304. Each slider 304 has a baffle 305 fixedly connected to its outer wall. A fixed shaft 306 is fixedly connected to the outer wall of the baffle 305 away from the sliders 304. A second mounting plate 307 is rotatably connected to the inner wall of the mounting plate 302. The second mounting plate 307 has a limit ring on its side near the mounting plate 302. When the second mounting plate 307 is engaged within the mounting plate 302, it is fixed to the mounting plate 302, preventing it from falling off and providing a certain degree of sealing. Several arc-shaped grooves 306 are formed on the inner wall of the end of the second mounting plate 307 near the fixed shaft 306. 8. The inner wall of the arc-shaped groove 308 is slidably connected to the outer wall of the fixed shaft 306. The outer wall of the mounting plate 307 is fixedly connected to the worm gear 309. The arc-shaped groove 308 can limit the movement trajectory of the fixed shaft 306, so that it can only move linearly along the direction of the fixed shaft 306 within the arc-shaped groove 308. The outer wall of the mounting plate 302 near the worm gear 309 is rotatably connected to the worm 310. The outer wall of the worm 310 meshes with the outer wall of the worm gear 309. When the worm 310 is rotated, there is meshing between the worm 310 and the worm gear 309. Therefore, the rotation of the worm 310 will drive the worm gear 309 to rotate, which in turn can drive the mounting plate 307 to rotate.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the materials to be chemically reacted are added into the chemical tank 1 through the inlet 102. The external waste gas collection device is installed on the connecting pipe of the mounting plate 307. Waste gas is generated during the reaction and is discharged from the exhaust pipe 101. During the discharge, the waste gas passes through the fixing plate 208 and squeezes the sealing gasket 209 and the continuously compressed spring 210, causing the sealing gasket 209 to gradually detach from the inner wall of the exhaust pipe 101. At this time, the waste gas can leak from between the sealing gasket 209 and the exhaust pipe 101. The exhaust gas flows out through the gap. When the exhaust gas flows in reverse, it will squeeze the sealing gasket 209 to make it stick tightly to the inner wall of the exhaust pipe 101. At this time, the exhaust gas cannot pass through the sealing gasket 209 normally into the chemical tank 1. The spring 210 will automatically reset the sealing gasket 209 through its own elastic force. When the exhaust gas enters the heat dissipation box 201, the heat conduction plate 202 will absorb some of the heat and transfer the heat to the fan blade 205 below the heat dissipation box 201. The motor 203 is started. The rotation of the motor 203 will drive the transmission shaft 204 to rotate, causing the fan blade 205 and the bristles to rotate. The rotation of the brush plate 206 and the fan blades 205 generates airflow, drawing outside air into the heat sink 201 from the dust cover 207 and expelling it from the side of the heat sink 201. This accelerates air circulation and dissipates heat from below the heat sink 201, effectively cooling the exhaust gas. The brush plate 206 also scrapes away dust adhering to the dust cover 207. When the user needs to control the flow rate of the exhaust gas within the connecting pipe 301, the worm gear 310 is rotated. The rotation of the worm gear 310 drives the worm wheel 309 to rotate, which in turn drives... The second mounting plate 307 rotates inside the mounting plate 302. The rotation of the second mounting plate 307 will drive the fixed shaft 306 to move linearly along the trajectory of the arc groove 308 through the arc groove 308. Since the annular groove 303 limits the movement trajectory of the slider 304, and the slider 304, the baffle 305 and the fixed shaft 306 are fixedly connected, the fixed shaft 306 will also move along the trajectory of the annular groove 303 when it moves. As a result, when the baffle 305 moves, the area enclosed between the baffles 305 will gradually change to facilitate the flow rate of the exhaust gas in the connecting pipe 301.
