It is classified differently according to the purpose of smelting, with common types including argon blowing refining furnaces and LF refining furnaces. The main production equipment includes RH refining furnaces and LF refining furnaces. It is a type of equipment used for removing impurities from crude metals in non-ferrous metallurgy or steel metallurgy. There are three types of refining furnaces used for copper pyrometallurgy: reverberatory furnaces, rotary furnaces, and tilting furnaces. Dust removal equipment, also called dust collectors or dust removal equipment, is equipment that separates dust from flue gas. Dust removal equipment utilizes underground dust removal water pipes and compressed air pipelines, adds certain additives to the water, introduces wind pressure, and completes a series of process flows through specialized equipment to generate foam, which is then sprayed onto the dust source through a distributor and nozzle bracket assembly. During the actual use of the refining furnace, a large amount of flue gas will be generated. The flue gas contains a large amount of particulate impurities. If it is directly discharged into the air, it will cause serious pollution to the atmosphere. During the actual process of exhaust gas dust removal, the exhaust gas dust removal device of the refining furnace is not effective in removing particulate matter in the exhaust gas of the refining furnace, and cannot fully remove the particulate matter in the exhaust gas.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a dust removal device for a refining furnace includes a support frame 1, a dust removal mechanism 2 is provided on the upper side of the support frame 1, two sets of visual windows 3 are fixedly provided on the front side of the dust removal mechanism 2, and a dust exhaust mechanism 4 is provided on the lower side of the dust removal mechanism 2. The dust removal mechanism 2 includes a dust removal frame 21 fixedly provided on the upper side of the support frame 1, an air inlet 22 is fixedly provided on one end of the dust removal frame 21 near the upper side, two sets of fixed plates 23 are fixedly provided on both sides of the dust removal frame 21, and a plurality of fixed rods 24 are fixedly welded to the inner sides of the four sets of fixed plates 23. The outer sides of the plurality of fixed rods 24 are fixedly welded to the inner sides of the plurality of fixed rods 24. Four groups of rings 25 are fixedly sleeved on the side, and two groups of filter screens 26 are fixedly sleeved on the outer sides of several groups of fixing rods 24 and the four groups of rings 25. Openings 27 are fixedly provided at the inner positions of the two groups close to one side of the four groups of fixing plates 23. The other end of the dust removal frame 21 is fixedly connected to the exhaust hood 28, and the upper end of the exhaust hood 28 is fixedly installed with an air pump 29. One side of the air pump 29 is fixedly connected to a connecting pipe 210, and the lower end of the connecting pipe 210 is fixedly connected to a connector 211. Clean air ports 212 are fixedly provided on the inner side of the connector 211 corresponding to the two groups of openings 27.

[0021] In this embodiment, two groups of visual windows 3 are fixedly provided on the front side of the dust removal frame 21, several groups of fixing rods 24 and two groups of filters 26 are arranged at an angle, the opening 27 passes through the inner position of the fixed plate 23 and is connected to the filter 26, the connector 211 is fixedly connected to the exhaust hood 28, and two groups of clean air ports 212 pass through one side of the exhaust hood 28.

[0022] Specifically, first, the exhaust pipe of the refining furnace is connected to the air inlet 22, and then the turbid air flow enters the inner side of the dust removal frame 21. After being filtered by the two sets of filter screens 26, the clean air flow will enter the inner side of the filter screen 26 and be discharged into the inner side of the exhaust hood 28 through the two sets of openings 27 for final discharge. However, the particulate matter will be blocked by the two sets of filter screens 26 and adhere to the outer sides of the two sets of filter screens 26. Over time, the filter screens 26 will become clogged, affecting the efficiency of the dust removal work. At this time, by starting the air pump 29, the high-pressure air flow is made to pass through the connecting pipe 210 and the connector 211 at a high frequency, and finally discharged to the two sets of openings 27 through the two sets of clean air ports 212. Then, the two sets of filter screens 26 are used to shake off the attached particulate matter through the high-frequency high-pressure air flow, thereby filtering the particulate impurities in the exhaust gas discharged from the refining furnace, avoiding serious pollution to the atmosphere, and having a good effect on removing particulate matter from the exhaust gas of the refining furnace, fully removing particulate matter in the exhaust gas, and avoiding clogging of the filter screen, thereby facilitating the long-term use of the device and having strong automation.

[0023] In this embodiment, the dust exhaust mechanism 4 includes a dust hopper 41 fixedly arranged at the lower side of the dust removal frame 21, and a protective cover 42 is fixedly connected to the lower side of the dust hopper 41 near one side, and a motor 43 is fixedly installed on the inner side of the protective cover 42, and one end of the motor 43 is fixedly connected to a discharge wheel 44. The lower side of the dust hopper 41 is movably connected to a dust collecting box 45, and lock buckles 46 are fixedly provided at the connection points on both sides of the dust hopper 41 and the dust collecting box 45. Three sets of universal wheels 47 are fixedly provided on the lower side of the dust collecting box 45, and the rotating shaft of the motor 43 passes through one side of the dust removal frame 21 and is connected to the discharge wheel 44, and the discharge wheel 44 is limited and movable on the inner side of the dust hopper 41.

[0024] Specifically, the discharge wheel 44 is driven to rotate by starting the motor 43, so that the shaken particulate impurities fall evenly, avoiding the blockage of the dust hopper 41 caused by the particles being too dense. When the dust discharge is completed, the two sets of locks 46 are opened to remove the dust box 45, and it is moved to the appropriate position through the three sets of universal wheels 47 to be poured out, which saves manpower, has a simple structure and is easy to operate.

[0025] Working principle:

[0026] When in use, first connect the exhaust pipe of the refining furnace with the air inlet 22, and then the turbid air flow enters the inner side of the dust removal frame 21, and is filtered by the two sets of filter screens 26. The clean air flow will enter the inner side of the filter screen 26 and be discharged into the inner side of the exhaust hood 28 through the two sets of openings 27, and finally be discharged. The particulate matter will be blocked by the two sets of filter screens 26 and attached to the outer side of the two sets of filter screens 26. As time goes by, the filter screens 26 will be blocked, affecting the efficiency of the dust removal work. At this time, by starting the air pump 29, the high-pressure air flow is made to pass through the connecting pipe 210 and the connector 211 at a high frequency, and finally discharged to the two sets of openings 27 by the two sets of clean air ports 212, so that the two sets of filter screens 26 will remove the particles attached to the two sets of filter screens 26 through the high-frequency high-pressure air flow. The particles are shaken down, thereby filtering the particulate impurities in the flue gas discharged from the refining furnace, avoiding serious pollution to the atmosphere, having a good effect on removing the particles in the exhaust gas of the refining furnace, being able to fully remove the particles in the exhaust gas, and avoiding clogging of the filter, which is convenient for long-term use of the device and has strong automation. In addition, the discharging wheel 44 is driven to rotate by the starting motor 43, so that the shaken particulate impurities fall evenly, avoiding clogging of the dust hopper 41 caused by excessive density of particles. When the dust discharge is completed, the two sets of locks 46 are opened to remove the dust box 45, and the dust box is moved to a suitable position through the three sets of universal wheels 47 to be poured out, which saves manpower, has a simple structure and is easy to operate.
