Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to an environmentally friendly box-type tempering furnace with a flue gas treatment device. Background Art

[0002] The box-type resistance furnace is a cyclically operated electric furnace, which is mainly used for heat treatment of metal parts or alloy steel parts in air. It is used in conjunction with a control cabinet to control the temperature of the electric furnace manually or automatically. However, it still has the following disadvantages in actual use.

[0003] At present, the existing box-type tempering furnace is usually relatively closed. When in use, it is usually impossible to intuitively and clearly view the heating conditions of the metal mechanical parts in the tempering furnace, which has certain limitations in use; and the existing box-type tempering furnace usually has a relatively simple structure and lacks relevant auxiliary structures, so it is impossible to fix the clamps or hooks used to clamp and hook the heated metal mechanical parts in the box-type tempering furnace, which has certain limitations in use.

[0004] For example, a box-type tempering furnace disclosed in Chinese patent CN219449791U has the advantage of being convenient for viewing the metal mechanical parts in the tempering furnace by providing an observation component, thereby solving the problem that the existing box-type tempering furnace is usually relatively closed, and when in use, it is usually impossible to intuitively and clearly view the heating conditions of the metal mechanical parts in the tempering furnace, and there are certain limitations in use; by providing a hanging component, it has the advantage of being convenient for fixing the clamps and hooks, thereby solving the problem that the existing box-type tempering furnace is usually relatively simple in structure and lacks relevant auxiliary structures, so that the clamps or hooks used for clamping and hooking the heated metal mechanical parts in the box-type tempering furnace cannot be fixed, and there are certain limitations in use.

[0005] However, the outer end of the box-type tempering furnace is not provided with a flue gas treatment structure, so that the flue gas generated during combustion cannot be purified.

[0006] For this reason, we urgently need to provide an environmentally friendly box-type tempering furnace with a flue gas treatment device. Utility Model Content

[0007] The utility model aims to provide an environmentally friendly box-type tempering furnace with a smoke treatment device to solve the problem in the background technology that the outer end of the box-type tempering furnace is not provided with a smoke treatment structure, thereby failing to purify the smoke generated during combustion.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly box-type tempering furnace with a flue gas treatment device, comprising a box-type tempering furnace and a treatment tube, the treatment tube is arranged at the right end of the box-type tempering furnace, a smoke outlet pipe is fixedly connected to the upper right end of the box-type tempering furnace, a smoke inlet pipe is fixedly connected to the lower left end of the treatment tube, a connecting pipe is connected between the smoke outlet pipe and the smoke inlet pipe, the box-type tempering furnace and the inner and outer ends of the treatment tube are connected with a treatment mechanism, the treatment mechanism comprises a treatment unit and a disassembly unit, the treatment unit is arranged at the inner and outer ends of the treatment tube, and the disassembly unit is arranged at the outer end of the connecting pipe.

Therefore, when the HEPA filter or the activated carbon filter is slid into the through slot and the fixing plate is moved to the front side of the treatment cylinder, the limiting holes at the left and right ends of the fixing plate will slide along the outer side of the threaded rod, thereby limiting the movement of the fixing plate.

[0011] A further improvement is that the inner side of the pressure ring is provided with an internal thread, the outer side of the threaded rod is threadedly connected to the inner side of the threaded rod, the rear side of the pressure ring abuts against the front sides of the left and right ends of the fixed plate, and the outer sides of the HEPA filter and the activated carbon filter abut against the inner side of the treatment tube.

[0012] A further improvement is that the disassembly and assembly unit includes a fixing ring, a connecting ring, a sliding ring and a mounting ring, the fixing ring is fixedly connected to the outer sides of the left and right ends of the connecting pipe, the connecting ring is connected to the outer side of the fixing ring, the sliding ring is fixedly connected to the end of the inner side of the connecting ring away from the box-type tempering furnace or the treatment tube, and the mounting ring is fixedly connected to the outer side of one end of the smoke outlet pipe away from the box-type tempering furnace and the outer side of one end of the smoke inlet pipe away from the treatment tube.

[0014] A further improvement is that the inner side of the connecting ring is slidably connected to the outer side of the fixed ring, the outer side of the sliding ring is slidably connected to the left and right ends of the outer side of the connecting pipe, the side of the sliding ring close to the box-type tempering furnace or the treatment tube abuts against the side of the fixed ring away from the smoke outlet pipe or the smoke inlet pipe, the end of the connecting pipe close to the box-type tempering furnace abuts against the end of the smoke outlet pipe away from the box-type tempering furnace, and the end of the connecting pipe close to the treatment tube abuts against the end of the smoke inlet pipe away from the treatment tube. Therefore, after placing the two ends of the connecting pipe on the outer ends of the smoke outlet pipe and the smoke inlet pipe, the connecting rings at both ends of the connecting pipe are threadedly connected to the outer side of the mounting ring until the sliding ring moves to contact the fixed ring, so that the connecting pipe can be fixed between the smoke inlet pipe and the connecting pipe, so that the smoke generated in the box-type tempering furnace can be discharged into the treatment tube through the connecting pipe for treatment.

Therefore, after the HEPA filter and the activated carbon filter are fixed to the inner side of the treatment cylinder, the rubber pads on the outer sides of the HEPA filter and the activated carbon filter contact the inner side of the treatment cylinder, so that the contact between the HEPA filter and the activated carbon filter and the inner side of the treatment cylinder can be kept sealed, so that the smoke entering the treatment cylinder is completely filtered by the HEPA filter and the activated carbon filter.

[0016] In summary, the present application discloses an environmentally friendly box-type tempering furnace with a flue gas treatment device.

[0017] This technical solution fixes the HEPA filter and the activated carbon filter to the inner side of the treatment cylinder, so that the flue gas entering the treatment cylinder will be filtered by the activated carbon filter and the HEPA filter in the treatment cylinder before being discharged, thereby purifying the flue gas.

[0018] Furthermore, by rotating the connecting ring so that it is removed from the outside of the mounting ring, the connecting pipe can be removed from between the smoke outlet pipe and the smoke inlet pipe, so that smoke dust in the connecting pipe can be processed after long-term use.
