Description

Technical Field

[0001] The utility model relates to the technical field of flue gas recovery of multi-purpose furnaces, in particular to a multi-purpose furnace with a flue gas recovery device. Background Technique

[0002] A multi-purpose furnace is a device that can perform multiple process treatments simultaneously, mainly used in the field of materials science. Through heat treatment processes, the wear resistance and corrosion resistance of products can be significantly improved, thereby increasing production efficiency. The design of the multi-purpose furnace enables multiple heat treatment processes, such as annealing, normalizing, quenching, and tempering, to be completed in the same device.

[0003] During the processing of the multi-purpose furnace, a large amount of flue gas is generated. The flue gas is often discharged through a flue gas exhaust pipe. However, this flue gas cannot be directly discharged outdoors as it will pollute the environment. Therefore, a flue gas recovery device is often set up to filter and incinerate the flue gas, thereby removing harmful components in the flue gas so that it can be discharged outdoors. However, some flue gas generated by multi-purpose furnaces often contains a large amount of large-volume ash residues. If these ash residues directly enter the flue gas treatment tank, it will cause the flue gas treatment tank to be easily blocked, and then the flue gas treatment tank needs to be frequently cleaned, increasing the workload. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a multi-purpose furnace with a flue gas recovery device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] The filtering rack includes an upper cover. The upper cover is installed on the upper surface of the filtering box. A plurality of filtering plates are arranged in a horizontal row at the bottom end surface of the upper cover.

[0009] In addition, the preferred structure is that a filtering cavity is opened in the filtering box. A gas inlet pipe is arranged in the middle of one side wall of the filtering box. A gas outlet pipe is arranged in the middle of the other side wall of the filtering box away from the gas inlet pipe.

The other side of the pre-filtering mechanism 03 far from the multi-purpose furnace body 01 is provided with a flue gas recovery unit 02, and the flue gas recovery unit 02 is used to recover and filter the flue gas.

[0025] Among them, the pre-filtering mechanism 03 includes a filtering box 3. A filtering rack 4 is installed on the filtering box 3. One side wall of the filtering box 3 is communicated with the first transmission pipe 2. The filtering rack 4 includes an upper cover 41. The upper cover 41 is installed on the upper surface of the filtering box 3. A plurality of filtering plates 42 are arranged horizontally and uniformly on the bottom surface of the upper cover 41. The filtering plates 42 can filter the ash residue and are convenient for replacement.

[0026] Moreover, a filtering cavity 33 is opened in the filtering box 3. The middle part of one side wall of the filtering box 3 is provided with an intake pipe 31. The middle part of the other side wall of the filtering box 3 far from the intake pipe 31 is provided with an exhaust pipe 32. Both the intake pipe 31 and the exhaust pipe 32 are communicated with the filtering cavity 33. The intake pipe 31, the exhaust pipe 32, the flue gas exhaust pipe 1, the first transmission pipe, the second transmission pipe 5, and the third transmission pipe 7 are all connected by a flange 9.

[0027] In addition, a placement groove 34 is opened on the upper surface of the filtering box 3. The upper cover 41 is installed in the placement groove 34. A plurality of mounting holes 35 are uniformly opened on the bottom wall of the placement groove 34. The placement groove 34 is used to place the upper cover 41.

[0028] And, a handle 412 is vertically arranged in the middle of the upper surface of the upper cover 41. A plurality of round holes 411 are opened on the side of the upper surface of the upper cover 41. The round holes 411 are coaxial with the mounting holes 35. The round holes 411 are used to install fixing components.

[0029] Meanwhile, the filter plate 42 can be inserted into the filter chamber 33. A filter screen 421 is provided on the filter plate 42. Sealing gaskets 422 are attached to the side walls of the filter plate 42 in contact with the filter chamber 33. The sealing gaskets 422 are fitted to the inner wall of the filter chamber 33, and the sealing gaskets 422 can prevent the flue gas in the filter chamber 33 from leaking out.

[0030] In addition, a sealing gasket 10 is attached to the bottom surface of the upper cover 41. The sealing gasket 10 is in contact with the bottom wall of the placement groove 34, and the sealing gasket 10 is convenient for preventing the flue gas from leaking out.

[0031] Meanwhile, the flue gas recovery unit 02 includes a flue gas treatment tank 8. A second transmission pipe 5 is provided at the intake end of the flue gas treatment tank 8.

[0032] In this embodiment, when the multi-purpose furnace body 01 is working, a large amount of flue gas will be generated in the cavity of its rear chamber. Under the suction of the exhaust fan 6, the flue gas will flow along the flue gas exhaust pipe 1, then enter the first transmission pipe 2, and then enter the filter chamber 33 of the filter box 3. When the flue gas passes through the filter box 3, the flue gas will pass through a plurality of filter plates 42. At this time, the filter screen 421 can block a large amount of ash in the flue gas, thereby preventing the flue gas from carrying a large amount of ash into the flue gas treatment tank 8.

[0033] After the flue gas comes out of the filter box 3, it enters the second transmission pipe 5, then enters the flue gas treatment tank 8 for further filtration, and then the flue gas without harmful substances after filtration will be discharged from the third transmission pipe 7.

[0034] And after the filter plate 42 has been filtering for a period of time, it is necessary to clean the ash on the filter screen 421. Just remove the fixing parts installed at the round holes 411, and then hold the handle 412 to remove the upper cover 41, and then the filter screen 421 on the filter plate 42 can be cleaned.

[0035] In the present utility model, by providing a pre-filtering mechanism 03 on the multi-purpose furnace body 01 with a flue gas recovery unit 02, before the flue gas enters the flue gas treatment tank 8 of the flue gas recovery unit 02, the flue gas will pass through multiple filter plates 42. In this way, the filter plates 42 can effectively filter out a large amount of ash carried in the flue gas, thereby preventing the flue gas from carrying ash into the flue gas treatment tank 8, which is likely to cause blockage of the flue gas treatment tank 8 and requires frequent cleaning. In this way, the workload of cleaning can be saved, and the filter rack 4 is also convenient for replacement and cleaning.
