[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0029] In this embodiment, it is given by Figures 1-4 The present utility model includes:

[0030] The transmission mechanism 1 for transporting processed parts can be used to transport the processed parts for movement. A furnace body 2 for pressing and forming the processed parts is installed on the transmission mechanism 1. An exhaust pipe 3 for smoke emission is installed at the top of the furnace body 2. Through the transmission mechanism 1, the processed parts can be transported into the interior of the furnace body 2 to complete the pressing and forming process, and then the processed parts completed inside the furnace body 2 are exported through the transmission mechanism 1. The smoke generated by the processing is exported through the exhaust pipe 3 at the top of the furnace body 2;

[0031] A smoke purification part 4 is arranged at the top of the exhaust pipe 3, and the smoke purification part 4 is used for purifying and cooling the gas exported from the furnace body 2;

[0032] Among them, the smoke purification part 4 includes a first fan 401 installed at one end of the exhaust pipe 3. The output end of the first fan 401 is installed with a gas transmission pipe 402. One end of the transmission pipe 402 is installed with a water storage tank 403 filled with water. A barrier net 404 for solid-liquid separation is installed in the inner cavity of the water storage tank 403, and the end of the transmission pipe 402 extending into the inner cavity of the water storage tank 403 penetrates through the barrier net 404. A first gas discharge hole 405 is opened at the top of the water storage tank 403. A slidable solid impurity collection box 406 is installed at the bottom of the inner cavity of the water storage tank 403. Bolts 407 are arranged outside the collection box 406, and the collection box 406 is connected to the outside of the water storage tank 403 through the bolts 407 to fix the collection box 406;

[0033] By starting the first fan 401, the airflow exported from the exhaust pipe 3 is guided into the interior of the transmission pipe 402. The transmission pipe 402 directly conducts the gas into the inner cavity of the water storage tank 403. An appropriate amount of water is injected into the water storage tank 403 in advance. In this way, the gas introduced into the water storage tank 403 will be purified by the water, and the impurities in the gas will be left in the water. The separated clean gas is separated and floats towards the top of the inner cavity of the water storage tank 403. Finally, the clean gas can be exported through the first gas discharge hole 405, avoiding polluting the environment by the discharged gas. At the same time, the gas purified by the water also realizes the cooling function, further preventing the situation of high surrounding temperature after the gas is discharged, and ensuring that the surrounding staff will not feel uncomfortable due to the high temperature of the discharged gas.

[0034] A support frame 5 is fixed in the inner cavity of the first gas discharge hole 405. A positioning column 6 is fixed at the top of the support frame 5. A protective cover 7 is threadedly connected to the top of the positioning column 6. A dust-proof net 8 is installed at the bottom of the protective cover 7. The setting of the dust-proof net 8 avoids external gas from bringing impurities into the interior of the water storage tank 403, ensures the cleanliness of the gas inside the water storage tank 403, and does not affect the intersection of the external gas and the gas inside the water storage tank 403. A sealing strip 9 is installed on the inner wall of the dust-proof net 8, and the inner wall of the sealing strip 9 is attached to the outer wall of the water storage tank 403;

[0035] The outer part of the protective cover 7 is fixedly installed with a handle rod 11 for rotary control;

[0036] The heat generated inside the water storage tank 403 due to air purification can be discharged to the inside of the protective cover 7 through the first gas discharge hole 405. The protective cover 7 is communicated with the external space through the dust-proof net 8. In this way, the heat discharge work inside the water storage tank 403 is realized, avoiding the situation that the water inside the water storage tank 403 gradually heats up due to the closed environment. At the same time, when filling water into the water storage tank 403, the handle rod 11 can be held to drive the protective cover 7 to rotate clockwise on the positioning column 6, and the protective cover 7 can be gradually raised. At this time, the protective cover 7 can be opened to close the water storage tank 403, and then water can be injected into the water storage tank 403.

[0037] A liquid spraying mechanism 12 is installed at the bottom of the support frame 5. The liquid spraying mechanism 12 can further purify and cool the gas, so that the water inside the water storage tank 403 is always in a circulating state. In this way, the heat of the flowing water is more likely to volatilize, preventing the water temperature inside the water storage tank 403 from being too high. A cooling mechanism 13 for cooling the surface of the workpiece on the transmission mechanism 1 is installed on one side of the water storage tank 403. Since the surface temperature of the workpiece is high after processing, it needs to wait for a long time to cool down when taking it. At this time, the low-temperature gas can be sprayed on the workpiece through the cooling mechanism 13 to accelerate the cooling, improving the taking speed of the workpiece;

[0038] The liquid spraying mechanism 12 includes a suspension frame 1201 fixed to the bottom of the support frame 5. A water pump 1202 is fixed to the bottom of the suspension frame 1201. A water suction pipe 1203 is installed at the input end of the water pump 1202, and a mist spray head 1204 is installed at the output end of the water pump 1202. After the water pump 1202 is powered on and started, the clean water at the top of the barrier net 404 can be pumped away through the water suction pipe 1203, and then sprayed into the inside of the water storage tank 403 through the mist spray head 1204. In this way, the atomized liquid can further contact the air inside the water storage tank 403, realizing the functions of secondary purification and secondary cooling of the gas. At the same time, the contact surface between the atomized liquid and the air is also larger, increasing the heat volatilization speed of the liquid;

[0039] The cooling mechanism 13 includes a second gas discharge hole 1301 formed on one side of the water storage tank 403. A second fan 1302 is installed outside the water storage tank 403 at the second gas discharge hole 1301. A first delivery pipe 1303 is fixed to the output end of the second fan 1302. One end of the first delivery pipe 1303 is fixedly installed with a corrugated pipe 1304. A second delivery pipe 1305 is fixedly installed at the bottom of the corrugated pipe 1304. A positioning frame 1307 is installed in the middle of the second delivery pipe 1305. A tightening ring 1308 for limiting the position of the second delivery pipe 1305 is installed in the inner cavity at one end of the positioning frame 1307. A gas injection box 1306 is fixedly installed at the bottom end of the second delivery pipe 1305, and a number of injection holes are formed at the bottom of the gas injection box 1306. At the same time, the gas injection box 1306 is arranged on the top of the transmission mechanism 1. When it is necessary to cool the workpieces completed inside the furnace body 2 on the transmission mechanism 1, only need to start the second fan 1302, and the second fan 1302 will extract the clean gas inside the water storage tank 403 through the second gas discharge hole 1301. At this time, the extracted gas can be transmitted to the corrugated pipe 1304 through the first delivery pipe 1303. The corrugated pipe 1304 will transmit the gas to the gas injection box 1306 through the second delivery pipe 1305. Finally, the gas injection box 1306 sprays clean and low-temperature gas on the surface of the workpiece through a number of injection holes to cool it, realizing the assistance of workpiece cooling, facilitating quick picking, and having a high overall processing efficiency. According to actual needs, since the length of the corrugated pipe 1304 is adjustable, the second delivery pipe 1305 can be pulled to move up and down to change the length of the corrugated pipe 1304. The second delivery pipe 1305 is position-limited on the positioning frame 1307 through the tightening ring 1308 and will only move under the pull of an external force. The gas injection box 1306 will move up and down synchronously with the second delivery pipe 1305. By changing the height of the gas injection box 1306, the contact distance between the low-temperature air and the workpiece can be changed. The closer the distance, the better the cooling effect.
