One is fuel combustion heating, including oil and gas; the other is electric heating. Carburizing furnace has two types: intermittent and continuous. Carburizing furnace performs high-temperature carburization heat treatment on the workpiece, and then quenches the workpiece to improve the hardness of the workpiece.

[0003] A high-temperature carburizing and quenching device for a carburizing furnace disclosed in Chinese Patent Publication No. CN219099233U is found. A threaded rod is arranged in the quenching box, and the threaded rod is driven to rotate by a motor to drive the movable block to move, so that the cleaning brush moves on the surface of the filter screen to clean the metal debris on the surface of the filter screen, and try to avoid the metal debris clogging the filter screen and affecting the cooling water discharge efficiency in the quenching box. A limiting rod is arranged to limit the movement of the movable block, and bolts are arranged to facilitate the installation and disassembly of the baffle. A rubber block is arranged to enhance the stability of the quenching box. A chip collecting bucket is arranged to facilitate the collection of cleaned metal debris, and the valve on the slag discharge pipe is opened to facilitate the discharge of the slag discharge pipe in the chip collecting bucket.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] Working principle: In summary, with the help of the above technical solution of the utility model, when it is necessary to process the metal workpiece, the metal workpiece is placed on the placement plate 203, and then the metal workpiece that needs to be carburized and quenched is fixed by the clamping structure 204, and then the electric slide rail 202 and the heating tube 201 are started by the external controller, and then the moving end of the electric slide rail 202 drives the fixed metal workpiece to move, and when entering the carburizing box 101, the metal workpiece is subjected to high-temperature carburization through the heating tube 201 (the carburizing process is not described in detail in the existing conventional technology). After the carburizing is completed, the carburized metal workpiece is transported to the quenching box 102 by the electric slide rail 202, and then the external controller is used to start the electric slide rail 202 and the heating tube 201. The motor 208 and the first delivery pump 213 are started, and then the output end of the motor 208 drives the threaded rod 206 to drive the adjustment plate 209 to reciprocate on the auxiliary rod 207. During the movement, the input end of the first delivery pump 213 generates suction, and then enters the liquid storage tank 212 to generate negative pressure, thereby delivering the cooling solution in the liquid storage tank 212 to the first output pipe 210, and then the cooling solution is delivered and sprayed onto the surface of the metal workpiece through the first output cover 211, thereby achieving a quenching effect on the metal workpiece, and then the waste liquid generated by the quenched metal workpiece and the debris generated by quenching fall into the guide cover 401 through the output port 3, and then are filtered through three first filter screens 402 with different apertures to achieve the waste liquid and metal debris. The separated waste liquid is then transported to the first collection box 403 after passing through the multi-layer first filter screen 402. When the first delivery pump 213 generates suction, the treated waste liquid is transported to the liquid storage tank 212 through the connecting pipe 413, thereby achieving the effect of repeated recycling and avoiding pollution to the environment, thereby ensuring the environmental protection effect. The debris filtered on the first filter screen 402 is started by the second delivery pump 410 through an external controller, and then the second delivery pump 410 generates suction to collect the filtered and separated debris through the collection cover 404, enter the delivery pipe 405 to transport it to the crushing cylinder 406, and the suction generated by the second delivery pump 410 causes the crushing tool 407 to rotate to crush the metal in the crushing cylinder 406 The metal debris is crushed, and then the crushed metal debris is conveyed to the filter box 408 by the suction force generated by the second conveying pump 410 and filtered through the second filter screen 5. During the filtering, the second filter screen 5 which is tilted is conveyed to the second collecting box 409 for collection, so that it can be processed and utilized again, thereby avoiding environmental pollution. Then the filtered gas is output from the second output cover 412 through the second output pipe 411 and sprayed onto the quenched metal surface, thereby better ensuring the quenching effect and cleaning the metal debris generated by the quenching again, thereby ensuring the heat treatment effect of the metal workpiece. After the quenching process is completed, the fixed workpiece is conveyed to the tempering box 103 through the electric slide rail 202.Then, the heating tube 201 is turned on by an external controller to perform low-temperature heat treatment on the metal workpiece.
