Description

Technical Field

[0001] The utility model relates to the field of fumigation furnaces, and more particularly to a dust collecting device for fumigation furnaces. Background Art

[0002] The smelting method of tin mainly depends on the material composition and content of the concentrate (or ore). Generally, the pyrometallurgical method is the main method, supplemented by the hydrometallurgical method. The purpose of pre-smelting treatment is to remove impurities such as sulfur, arsenic, antimony, lead, bismuth, iron, tungsten, niobium, and tantalum that are harmful to smelting, and at the same time achieve the purpose of comprehensively recovering various useful metals. In the document with publication number CN218107087U, a dust collection device for a fuming furnace is proposed. The flue gas enters the filter box through the exhaust pipe. After passing through filters with different mesh sizes, the dust and other particulate matter in the flue gas are fully filtered and then discharged from the connecting pipe for recovery. The above-mentioned dust collection device uses filters with different mesh sizes to collect dust. It is necessary to open the movable door and clean the filter with a brush. However, when in use, the dust flows back into the electric furnace. However, the dust easily adheres to the return pipe, which affects the smelting of oxides in the electric furnace and is relatively inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem in the prior art that dust is easily attached to the reflux pipe, which affects the smelting of oxides in the electric furnace. A dust collection device for a fuming furnace is provided to solve the above shortcomings and is convenient to use.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:

[0012] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) The utility model provides a dust collection device for a fumigation furnace. Through the provided strip grooves, filter screens, brush layers, inclined strips and collection pipes, the smoke will pass through the interior of the collection pipe when it refluxes. The tin in the slag of the fumigation furnace is sulfided into volatile stannous sulfide, which is volatilized and oxidized into oxides and recovered to the electric furnace in the form of smoke for treatment. The provided filter screens and filter bags will block the dust in the smoke and collect the smoke in a centralized manner. The motor controls the rotating shaft to rotate, causing the brush blocks to rotate on both sides of the filter screen. The brush layer cleans the dust and the dust falls into the interior of the collection pipe. The cylinder contracts and uses the inclined strips to push the smoke at the bottom of the collection pipe. The inclined strips move from the bottom of the mounting frame. Since one end of the collection pipe is downward, when the inclined strips collide with the neutral plate, the smoke inside the strip grooves is dumped, making it easier to dump the material.

[0015] (2) The utility model provides a dust collection device for a fumigation furnace. By providing a filter bag, a moving bar and a slot, when the cylinder contracts, a push rod will pass through the interior of the rear plate, and one end of the push rod will push the push bar, so that the filter bag is moved out from the interior of the collection pipe. The filter bag drives the moving bar to move from the interior of the slot, and the connecting spring is deformed, so that the lower end of the filter bag is at a certain distance from the collection pipe, so that the smoke dust inside the bar slot is moved out from one end of the interior of the collection pipe, which can facilitate the electric furnace to further smelt the smoke dust and avoid the waste of oxides.

[0026] Combine Figure 2-5The control mechanism 15 includes a mounting cylinder 151 and a motor 152 mounted at the middle end of the mounting cylinder 151. A rotating shaft 153 is mounted on the output end of the motor 152. A brush block 154 is mounted on the outer surface of the rotating shaft 153. The brush block 154 includes a mounting strip 1541 and a rubber strip 1542 mounted on one end of the mounting strip 1541. A brush layer 1543 is mounted on one end of the rubber strip 1542. The brush layer 1543 cleans the smoke and dust attached to the filter screen 14. A neutral plate 112 is mounted on the bottom end of the collecting pipe 11 and on one side of the bottom groove 111. A rear plate 114 is mounted on the edge of the bottom end of the collecting pipe 11. The middle ends of the neutral plate 112 and the rear plate 114 are provided with through holes 113 of the same height. A filter bag 118 is mounted on the inside of the collecting pipe 11 and on the side away from the bottom groove 111. The filter bag 118 is used to filter smoke and dust. One end of the collecting pipe 11 The filter bag 118 is provided with a slot 117 on the lower side, and moving bars 119 are installed on both sides of the lower end of the filter bag 118. The moving bar 119 is slidably installed in the interior of the slot 117. A connecting spring 116 is installed between one end of the slot 117 and the interior of the slot 117. A push bar 115 is installed on one side of the filter bag 118, and the push bar 115 is at the same height as the rear plate 114. The slot 117 is used to pull back the moving bar 119 and the moving bar 119. The cleaning mechanism 16 includes an inclined surface 161 and a strip groove 162 opened on one side of the inclined surface 161, and the bottom end of the inclined surface 161 contacts the bottom end of the collecting pipe 11, and the inclined surface 161 is set toward one side of the neutral plate 112 for pushing the material. The bottom end of the inclined surface 161 is provided with a bottom slider 163, and the bottom slider 163 matches the bottom slot 111. A push rod 164 is installed inside the strip groove 162, and the push rod 164 is slidably installed inside the through hole 113.

[0027] In this embodiment, when the flue gas refluxes, it will pass through the interior of the collection pipe 11. The tin in the slag of the fuming furnace will be sulfided into volatilized stannous sulfide and volatilized, oxidized into oxides, and recovered to the electric furnace for treatment in the form of flue gas. The filter screen 14 and filter bag 118 will block the dust in the flue gas and collect the dust in a centralized manner. The motor 152 controls the rotating shaft 153 to rotate, prompting the brush block 154 to rotate on both sides of the filter screen 14, and the rubber strip 1542 pushes the brush layer 1543 toward the filter screen. 14, so that the brush layer 1543 cleans the dust, and the dust falls into the interior of the collection pipe 11. The cylinder 17 contracts and pulls the bottom slider 163, so that the bottom slider 163 moves inside the bottom groove 111 toward the side of the filter bag 118. The inclined surface 161 moves at the bottom end of the collection pipe 11, and the inclined surface 161 is used to push the smoke at the bottom end of the collection pipe 11. The inclined surface 161 moves from the bottom end of the mounting frame 12. Since one end of the collection pipe 11 is facing downward, the smoke at the bottom end of the collection pipe 11 is pushed. When the inclined surface 161 collides with the neutral plate 112, the smoke and dust inside the strip groove 162 are dumped, which is convenient for dumping. When the cylinder 17 contracts, the push rod 164 passes through the inside of the rear plate 114. One end of the push rod 164 pushes the push strip 115, so that the filter bag 118 is moved out of the inside of the collection pipe 11. The filter bag 118 drives the moving strip 119 to move from the inside of the groove 117, and the connecting spring 116 is deformed, so that the lower end of the filter bag 118 is in a certain distance from the collection pipe 11. The distance allows the smoke inside the strip groove 162 to move out from one end of the interior of the collecting tube 11, which can facilitate the electric furnace to further smelt the smoke and avoid wasting oxides. When the cylinder 17 is extended, the connecting spring 116 will pull the moving strip 119 back to the interior of the groove 117, and the filter bag 118 will move to the interior of the collecting tube 11. The push strip 115 will contact the rear plate 114, and the filter bag 118 will be used to block one end of the collecting tube 11 to prevent the smoke from flowing back into the interior of the electric furnace.
