[0031] The difference between the present embodiment and embodiment 1 is that the purification treatment device 3 includes a connecting box 31, activated carbon 33, a connecting pipe 34 and a filter screen 35, the connecting pipe 34 is installed above the furnace chamber 6 and below the exhaust pipe 4, the connecting box 31 is installed between the exhaust pipe 4 and the connecting pipe 34, two filter screens 35 are installed inside the connecting box 31, and the activated carbon 33 is filled between the two filter screens 35.

[0036] The structure and principle of the exhaust pipe 4, the permeating agent pipe assembly 5 composed of the permeating agent pipe and the valve, the furnace chamber 6, and the material pushing and pulling assembly 7 composed of the bottom plate, the pushing plate, the first rotating rod, the second rotating rod, the first gear, the second gear, the half gear, the hook pulling mechanism, the material plate, the hook block, the driving motor, and the supporting leg in the present utility model have been disclosed in a carburizing multi-purpose furnace adopting a material pushing and pulling mechanism with Chinese patent application No. 202321442479.5. The working principle is that during work, the material is first placed on the material plate. When the material needs to be pushed, the hook claw is actuated to rotate by half a circle around the round rod and make the hook claw as a whole located directly above the pushing plate. Then, the driving motor is started. The driving motor drives the first gear to rotate through the first rotating rod, drives the second rotating rod to rotate through the second gear, and drives the half gear to rotate when the second rotating rod rotates. At this time, the half gear on one side will engage with the pushing plate. When the half gear on one side rotates to the end, the pushing plate will also move to the end and push the material plate into the furnace chamber. Then, the half gear on one side will continue to rotate and no longer engage with the pushing plate, but at this time, the half gear on the other side will engage with the pushing plate and bring the pushing plate back to the initial end on the other side in the same direction of rotation. At this time, the material is pushed. Then, the carburizing process can be normally carried out. When the material needs to be pulled, the hook claw is only actuated again to rotate by half a circle and partially extend out of the pushing plate. Then, the driving motor is started again. The pushing plate will drive the hook claw to move and approach the hook block on the material plate. When the hook claw moves to the hook block, it can be lifted by the inclined surface. When the pushing plate moves to the end, the hook claw will fall on the hook block at the groove and hook the hook block. Then, the pushing plate can pull out the material plate through the hook claw. The problem that the existing carburizing multi-purpose furnace pushing and pulling mechanism uses a chain that is easy to wear and tear and affects production efficiency is solved. The above is the working principle of the carburizing multi-purpose furnace adopting the material pushing and pulling mechanism.
