Description

Technical Field

[0001] The present application relates to the technical field of nitrocarburizing treatment devices, and more specifically, to a nitrocarburizing surface hardening treatment device. Background Art

[0002] Nitrogen-carbon-oxygen co-penetration is a device that forms a high-hardness, wear-resistant coating on the surface of a material through surface hardening. For example, a coating is formed on the surface of a screw to improve the strength of the screw. The device usually uses ion penetration technology to inject elements such as nitrogen, carbon and oxygen into the surface of the material, and through reaction, a compound layer such as nitride, carbide and oxide is generated to increase the hardness, wear resistance and surface properties of the material.

[0003] In the related technology, harmful gases are sucked out by a fan. For example, a patent with the prior art publication number CN218710788U provides a nitrogen-carbon-oxygen co-diffusion treatment equipment for crawler crane axle pin treatment. The exhaust pipe in the device is fixedly connected to the top of the box, the activated carbon block is bonded to the inner wall of the exhaust pipe, and the suction fan is fixedly connected to the inner wall of the exhaust pipe. The suction fan sucks out the harmful gases and removes the harmful gases through the activated carbon block.

[0004] Although the above-mentioned prior art solution can achieve the effect of sucking harmful gases out of the outside through the exhaust fan, it still has the following defects: a large amount of impurities will accumulate on the inner wall of the exhaust pipe after long-term use. The impurities will affect the exhaust volume and exhaust efficiency, causing harmful gases to accumulate in the box, affecting the nitrogen-carbon-oxygen co-diffusion treatment.

[0005] In view of this, we propose a nitrocarburizing surface hardening treatment device. Utility Model Content

The activated carbon layer 205 can effectively remove organic gases, odors and some volatile harmful gases. The molecular sieve 206 can selectively adsorb molecules of a specific size and has a good removal effect on certain gases. The aluminum oxide layer 207 is used to remove acidic gases such as hydrogen sulfide H2S and ammonia NH3, thereby improving the emission quality of the gas. The condenser 203 is started so that cooling water flows inside the condenser tube 204, thereby cooling the high-calorie harmful gases and preventing the harmful gases from overheating and damaging the components.

[0039] Start the motor 301 in the exhaust mechanism 3, so that the driving gear 302 drives the outer ring of the one-way bearing 303 to rotate, while the inner ring of the one-way bearing 303 does not rotate. The rotation of the driving gear 302 also drives the exhaust gear ring 306 to rotate. The rotation of the exhaust gear ring 306 causes the shaftless fan blades 307 to rotate and generate suction, so that the harmful gas is discharged to the outside through the exhaust channel 2 and the first connecting pipe 308, thereby achieving the effect of exhausting gas.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The cleaning mechanism 4 includes a linkage gear 401, which is fixedly arranged at one end of the transmission rod 304. A cleaning toothed ring 402 is meshed on the outer side of the linkage gear 401. A cleaning brush 403 is fixedly arranged on the inner side of the cleaning toothed ring 402. The cleaning brush 403 is fixedly connected to a cleaning scraper 404 through a short rod. The cleaning scraper 404 is arranged to fit the inner wall of the first pipe 308. A second cover 407 is arranged on the outer side of the linkage gear 401 and the cleaning toothed ring 402. A second connecting pipe 406 is fixedly provided at the top, the linkage gear 401 is rotatably provided at the inner top of the second cover shell 407, a connecting plate 310 is rotatably provided at the bottom end of the cleaning gear ring 402, the connecting plate 310 is rotatably provided at the outer side of the transmission rod 304, the connecting plate 310 is fixedly provided at the outer side of the first connecting pipe 308, a blocking net 405 is rotatably provided at the outer side of the short rod, the blocking net 405 is fixedly provided at the inner side of the connecting plate 310, and the second cover shell 407 is fixedly provided at the top of the connecting plate 310.

[0041] When cleaning impurities on the inner wall of the first connecting pipe 308, the driving gear 302 rotates in the opposite direction, and the one-way bearing 303 rotates as a whole, thereby driving the transmission rod 304 and the linkage gear 401 in the cleaning mechanism 4 to rotate. The rotation of the linkage gear 401 drives the cleaning gear ring 402 to rotate. The rotation of the cleaning gear ring 402 drives the cleaning brush 403 to rotate, which is used to clean large particles of impurities on the blocking net 405. The cleaning brush 403 drives the cleaning scraper 404 to rotate through the short rod. The cleaning scraper 404 is used to clean impurities on the inner wall of the first connecting pipe 308, thereby improving the exhaust volume and exhaust efficiency.

[0042] Working principle: When the harmful gas is discharged by nitrogen-carbon-oxygen co-penetration treatment, the motor 301 in the exhaust mechanism 3 is started, so that the driving gear 302 drives the outer ring of the one-way bearing 303 to rotate, and the inner ring of the one-way bearing 303 does not rotate. The rotation of the driving gear 302 also drives the exhaust gear ring 306 to rotate. The rotation of the exhaust gear ring 306 causes the shaftless fan blade 307 to rotate to generate suction, so that the harmful gas is discharged to the outside through the exhaust channel 2 and the first connecting pipe 308. The harmful gas will pass through the activated carbon layer 205, the molecular sieve 206 and the aluminum oxide layer 207. The activated carbon layer 205 can effectively remove organic gases, odors and some volatile harmful gases. The molecular sieve 206 can selectively adsorb molecules of a specific size and has a good removal effect on certain gases. The aluminum oxide layer 207 is used to remove acidic gases such as hydrogen sulfide H2S and ammonia NH3, thereby improving the emission quality of the gas. The condenser 203 is moved so that cooling water flows inside the condenser tube 204, thereby cooling the high-calorie harmful gases and preventing the harmful gases from overheating and damaging the components. When cleaning the impurities on the inner wall of the first connecting pipe 308, the driving gear 302 rotates in the opposite direction, and the one-way bearing 303 rotates as a whole, thereby driving the transmission rod 304 and the linkage gear 401 in the cleaning mechanism 4 to rotate. The rotation of the linkage gear 401 drives the cleaning gear ring 402 to rotate. The rotation of the cleaning gear ring 402 drives the cleaning brush 403 to rotate, which is used to clean the large particles of impurities on the blocking net 405. The cleaning brush 403 drives the cleaning scraper 404 to rotate through the short rod. The cleaning scraper 404 is used to clean the impurities on the inner wall of the first connecting pipe 308, thereby increasing the exhaust volume and exhaust efficiency. At the same time, the electronic valve 202 is opened so that the impurities can be discharged to the outside through the ash outlet channel 201 to prevent the harmful gases from affecting the nitrogen-carbon-oxygen co-penetration treatment.
