In this embodiment, the adjusting device is a first elastic member, and the first elastic member is fixedly disposed between the guide block 320 and the lower end of the first slideway 111. Specifically, first elastic component is first spring, and after the flue gas got into first passageway 330, impurity in the flue gas filtered the hole shutoff on with the first surface gradually, and the flue gas that has certain velocity of flow can't pass the filtration hole on the first surface, and the flue gas of certain velocity of flow acts on the first surface, makes filter screen 310 have decurrent power, extrudees first spring, and then makes filter screen 310 wholly slide downwards along first slide 111. After the flue gas enters the second channel 340, the flue gas leads to the first channel 330 from the second channel 340, the filtering holes on the first surface are subjected to back flushing, impurities blocking the filtering holes on the first surface are gradually cleaned, the air permeability of the filter screen 310 is increased, and the first spring is gradually restored to the initial state.
In this embodiment, a baffle 520 is fixedly disposed below the blocking plate 510, and the baffle 520 is used for collecting impurities blocking the filter screen 310. Specifically, the air holes are formed in the baffle 520, the baffle 520 is obliquely arranged in a manner of being close to the blocking plate 510, the peripheral wall of the baffle 520 can be rotatably and slidably abutted to the inner wall of the pipeline 110 up and down, so that when smoke blows back the filtering holes in the first surface or the second surface, impurities blocking the filtering holes in the first surface or the second surface are gradually removed from the blocking of the filter screen 310 and gradually accumulated on the baffle 520, and the impurities are gradually concentrated below the blocking plate 510 due to the oblique arrangement of the baffle 520.
With the above embodiments, the usage principle and the working process of the present invention are as follows:
when the device works, the upper end of the pipeline 110 is communicated with the roasting chamber, a blower is arranged at a smoke outlet of the roasting chamber, and when minerals are roasted, smoke generated by roasting passes through the pipeline 110 from top to bottom at a certain flow speed and then is discharged.
In the interior of the duct 110, the filter screen 310 with a spiral structure uniformly divides the duct 110 into a first channel 330 and a second channel 340, when the flue gas enters the duct 110, the flue gas can only enter one of the first channel 330 or the second channel 340 under the action of the air deflector 210, and as the blocking plate 510 is rotatably arranged at the lower end of the filter screen 310 and the blocking plate 510 is fixedly connected with the guide rod through the connecting rod 410, the first channel 330 or the second channel 340 into which the flue gas enters is a relatively closed space and can only be communicated with the second channel 340 or the first channel 330 through the filtering holes on the filter screen 310.
In this embodiment, for example, when the flue gas first passes through the first channel 330, the first channel 330 with the spiral structure makes the flue gas fully contact with the first surface of the filter screen 310, and the impurities in the flue gas gradually block the filter holes on the first surface. The permeability of the first surface is gradually reduced as the smoke is filtered. Because the fixed guide block 320 that is provided with in filter screen 310 upper end, guide block 320 can slide along first slide 111 and set up, and the fixed first spring that is provided with between the lower extreme of guide block 320 and the lower extreme of first slide 111, the flue gas that has certain velocity of flow pushes gradually filter screen 310 and compresses first spring, makes filter screen 310 slide along first slide 111.
The upper end of the air deflector 210 is fixedly provided with a rotating shaft 220, the rotating shaft 220 is fixedly provided with fan blades 230, and when the smoke enters the duct 110, the fan blades 230 tend to rotate. The air deflector 210 is rotatably connected to the upper end of the filter screen 310, so that when the filter screen 310 slides along the first sliding channel 111, the air deflector 210 slides along the first sliding channel 111 at the same time. When the air deflector 210 slides to the position where the first sliding part is communicated with the second slideway 112, the air deflector 210 slides along the second slideway 112 under the action of the fan blade 230, so that the flue gas is converted to be led to the second channel 340. Along with the rotation of the air guiding plate 210, the blocking plate 510 is driven to rotate synchronously.
When the flue gas changes and gets into second passageway 340, the flue gas accesss to second passageway 340 back this moment, carries out the blowback through the filtration pore pair first surface of second surface filtration pore, makes the impurity of blockking up the filtration pore of first surface clear up, and the gas permeability of filter screen 310 increases, under the effect of first spring reset force, makes filter screen 310 resume to initial height gradually. Impurities in the flue gas are accumulated in the filtering holes and are difficult to mix with the flue gas again after being cleaned, so that the content of the impurities in the flue gas is reduced.
A baffle plate 520 is fixedly arranged below the blocking plate 510, and the smoke filtered by the filter screen 310 can directly pass through the air holes on the baffle plate 520. When the flue gas accesss to second passageway 340, the flue gas is cleared up the impurity in the filter pore on to the first surface, make impurity accumulate gradually at the up end of baffle 520, because baffle 520 slope sets up, make baffle 520 landing to lower one end gradually, reduce the hindrance to baffle 520 bleeder vent, because the lower end of baffle 520 slope sets up in the below of shutoff board 510, make impurity gather gradually and the below of shutoff board 510, can effectively avoid the flue gas after the filtration to disturb impurity once more when baffle 520, improve the collection effect to the smoke and dust. Further improving the period of disassembling and cleaning the pipeline 110, thereby improving the treatment efficiency of the flue gas.
In other embodiments, the filter screen 310 is vertically disposed, and the filter screen 310 is located on the axis of the pipe 110, so that a first channel 330 defined by a first surface of the filter screen 310 and an inner wall of the pipe has the same volume as a second channel 340 defined by a second surface of the filter screen 310 and the inner wall of the pipe, and the first channel 330 and the second channel 340 have the same filtering effect.
In other embodiments, the air deflector 210 is not slidably disposed along the second runner 112; the guide block 320 at the upper end of the filter screen 310 is disposed on the upper portion of the first slide rail 111, and the rotating shaft 220 of the reversing device is fixedly connected to the filter screen 310, so that when the filter holes on the first surface or the second surface of the filter screen 310 are blocked, the guide block 320 slides to the communication position between the first slide rail 111 and the second slide rail 112, and under the action of the fan blade 230, the guide block 320 slides along the second slide rail 112, thereby changing the smoke entering the first channel 330 or the second channel 340.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
