Description

Technical Field

[0001] The utility model relates to the technical field of tempering furnace oil fume emission, in particular to a tempering furnace oil fume emission device. Background Art

[0002] The tempering furnace is used for tempering general metal parts in the air, as well as quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die-castings, pistons, aluminum plates, etc. The tempering furnace will produce fumes when in use. These fumes are generally discharged directly to the outside, causing pollution to the environment, so the fume emissions of the tempering furnace need to be treated.

[0003] A Chinese patent discloses a tempering furnace oil fume purification device (authorization announcement number CN214735955U). The patented technology first connects the tempering furnace exhaust pipe to the connecting pipe, and sends the oil fume into the interior of the shell through the air pump. Then, the sprayer connected to the water inlet pipe will spray the cleaning liquid. After the smoke is cleaned, the sewage will flow into the interior of the water tank and then be discharged through the drain pipe. The grease in the smoke will float on the water due to its characteristics, and then flow into the bottom of the inner cavity through the through holes set in the side baffle, and then be discharged through the oil outlet pipe. At the same time, the treated gas inside the inner cavity is discharged through the exhaust port, thereby achieving a high-efficiency purification effect.

[0004] However, there are still some shortcomings in this patent. Although this patent can process the oil fume discharged from the tempering furnace, it can be seen from the drawings of the patent that this patent directly sprays the oil fume with cleaning liquid, and does not recover the waste heat of the oil fume, which will cause the heat in the oil fume to be directly lost and cause losses. Therefore, those skilled in the art provide a tempering furnace oil fume exhaust device to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model aims to provide a tempering furnace oil fume exhaust device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A partition is arranged inside the processing box, a gas outlet plate is connected to the lower surface of the partition, a processing net is installed on one side of the partition inside the processing box, and a liquid storage tank is arranged on one side of the processing box.

[0013] As a further solution of the utility model: heat-conducting rods are symmetrically arranged inside the waste heat recovery box outside the fixed cylinder, and the material of the heat-conducting rods is copper.

[0014] As a further solution of the utility model: the partition plate is vertically arranged to the processing net, and air holes are opened on the outside of the air outlet plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1.
