Description

Technical Field

[0001] The invention relates to the field of cleaning technology, in particular to a self-cleaning mechanism of a dust removal hood for copper smelting processing. Background Art

[0002] During the copper smelting process, a large amount of flue gas and smoke are inevitably generated due to the physical and chemical effects such as the combustion of fuel, the carrying effect of airflow on materials, and the volatilization and oxidation of metals at high temperatures. The flue gas mainly contains gaseous pollutants such as SO2, SO3, CO and CO2, and the smoke dust is a large amount of dust particles. In order to protect the workshop environment, a dust hood needs to be installed above the furnace for covering, and the smoke and flue gas are extracted to the environmental protection purification system for harmless treatment through negative pressure extraction. In the case of heavy dust, a pre-coarse filter structure needs to be set in the dust hood to prevent a large amount of dust from being inhaled into the transmission air duct and causing pipeline blockage. Subsequent cleaning and maintenance are extremely difficult. In actual use, the dust adhesion speed of the coarse filter is fast and it is very easy to get blocked. It needs to be cleaned manually frequently, which affects the smelting efficiency. Summary of the invention

The one-way beam cone bucket is in the shape of a cone cylinder, and its diameter gradually decreases from top to bottom, and the bottom is open. The upper eave of the one-way beam cone bucket can be sealed and matched with the inner wall of the fixed cone eave. A cone bucket tension spring is connected between the one-way beam cone bucket and the inner wall surface of the side arc tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The self-cleaning mechanism of the dust hood of the present invention can automatically complete the self-cleaning of the coarse filter screen and automatically collect the dust filtered out by the coarse filter while coarse filtering the smoke; the coarse filtering is alternately inserted into the upper plug-in frame and the lower plug-in frame, and the coarse filtering will not be interrupted during the self-cleaning process, thereby preventing large particles of dust from entering the subsequent air duct and causing the air duct to be blocked.

[0016] And through the self-cleaning outer chamber and switching mechanism and other structural settings, the coarse filter has sufficient static time after vibration dust removal, so that the dust can be stored in the pull-out ash hopper, which is convenient for unified maintenance and cleaning.

[0017] During the process of alternating the upper and lower plug-in frames, there is a situation where the two are connected in series at the same time. At this time, the gas needs to pass through two sets of coarse filters at the same time. When the exhaust pressure at the air duct connection port remains unchanged, the suction pressure at the dust suction groove will be reduced, affecting the smoke capture effect of the dust hood. The side arc tube, one-way beam cone bucket and corrugated bag and other structures are set to automatically replenish the suction when the suction pressure at the dust suction groove is reduced, so that the gas is buffered in the corrugated bag to ensure the suction flow at the dust suction groove when the two sets of coarse filters are connected in series; and the one-way beam cone bucket structure is set to play a one-way beam role, so that after the corrugated bag inhales air, it is beamed when feeding back the gas, ensuring that the small flow of gas slowly returns to the rear wall cavity, which is convenient for suction at the air duct connection port. At the same time, its conical structure can facilitate the discharge of dust after a certain amount of dust is inhaled in the corrugated bag, avoiding dust accumulation in the corrugated bag.

[0029] like Figure 5 As shown in , the switching mechanism includes a telescopic drive cylinder 901 and a connecting end block 902. The connecting end blocks 902 are fixedly arranged on the sides of the upper plug-in frame 7 and the lower plug-in frame 8, respectively. There are two groups of telescopic drive cylinders 901, and both are fixed on the outer surface of the self-cleaning outer chamber 9. The telescopic shafts of the telescopic drive cylinders 901 are respectively connected and fixed to the corresponding connecting end blocks 902, and the surfaces of the two groups of connecting end blocks 902 are respectively fixed with vertical shifting blocks 903. A swing support 904 is fixedly arranged on the inner wall surface of the self-cleaning outer chamber 9, and a control swing arm 905 is rotatably arranged in the swing support 904. A reset spring 906 is connected between the control swing arm 905 and the inner wall surface of the self-cleaning outer chamber 9, and a vertical rod 907 is vertically fixedly arranged on the control swing arm 905.

[0030] A dustproof motor 908 is fixedly installed at the end of the vertical rod 907, and an impact rotary block 909 is installed on the rotating shaft of the dustproof motor 908. The impact rotary block 909 is driven to rotate by the dustproof motor 908; when the upper plug-in frame 7 moves to the inside of the self-cleaning outer chamber 9, the impact rotary block 909 will contact the coarse filter screen 10 corresponding to the upper plug-in frame 7; when the lower plug-in frame 8 moves to the inside of the self-cleaning outer chamber 9, the impact rotary block 909 will contact the coarse filter screen 10 corresponding to the lower plug-in frame 8.

[0031] The side wall of the rear wall cavity 2 is connected to a side arc tube 201, on which a fixed chassis 202 is fixedly installed, a lifting top plate 203 is arranged above the fixed chassis 202, a bellows 204 and a reset spring 205 are connected between the lifting top plate 203 and the fixed chassis 202, the reset spring 205 provides an elastic tension so that the lifting top plate 203 and the fixed chassis 202 have a tendency to elastically move closer, a positioning optical axis 206 is fixedly arranged on the lower surface of the lifting top plate 203, the positioning optical axis 206 is limitedly inserted through the fixed chassis 202, and the positioning optical axis 206 is in sealing contact with the fixed chassis 202. A right-angle lifting piece 207 is fixedly provided on the upper surface of the lifting top plate 203, an active turntable 208 is provided outside the right-angle lifting piece 207, and a turntable arm 209 is fixedly provided on the active turntable 208. When the active turntable 208 rotates, the lifting top plate 203 can be driven to rise through the cooperation of the turntable arm 209 and the right-angle lifting piece 207.

[0032] The inner wall surface of the side arc tube 201 is fixedly provided with a fixed cone eave 210, and a one-way beam cone hopper 211 is provided in the fixed cone eave 210. The one-way beam cone hopper 211 is in a cone shape, and the diameter gradually decreases from top to bottom, and the bottom is open. The upper eaves of the one-way beam cone hopper 211 can be sealed with the inner wall of the fixed cone eave 210, and a cone hopper tension spring 212 is connected between the one-way beam cone hopper 211 and the inner wall surface of the side arc tube 201; Figure 8 As shown in the figure, when the airflow in the side arc tube 201 flows upward, the one-way beam cone 211 will be pushed open. At this time, there will be no beam flow and the gas will flow normally. When the airflow in the side arc tube 201 flows downward, the airflow can only flow through the bottom opening of the one-way beam cone 211, so that the gas absorbed in the corrugated bag 204 is released into the rear wall cavity 2 very slowly, minimizing the impact of gas input.

[0033] The inner wall surfaces of the upper slot 5 and the lower slot 6 are respectively provided with accommodating gate grooves 501 , in which an inclined gate tongue 502 is arranged, and a downward pressing spring 503 is arranged above the inclined gate tongue 502 .

[0034] A limit clamp 910 is fixedly provided on the inner wall surface of the self-cleaning outer chamber 9. There are two groups of limit clamps 910, which correspond to the upper insertion frame 7 and the lower insertion frame 8 respectively. A pull-out ash hopper 911 is provided at the lower part of the self-cleaning outer chamber 9.

[0035] A feeding pipe 101 is connected to the upper part of the dust removal hood 1, a working port 102 is opened at the front part of the dust removal hood 1, a furnace bottom port 103 is opened at the bottom of the dust removal hood 1, and an inspection reserved groove 104 is opened on the side wall surface of the dust removal hood 1. The inspection reserved groove 104 is used to install an online inspection device.

[0036] When the dust cover self-cleaning mechanism of the present invention is used, Figure 1 As shown in the figure, the work surface 11 is usually the ground or a building platform, and the smelting furnace 12 is a melting furnace used for smelting. When the work surface 11 is the ground, the smelting furnace 12 is set in a downward excavation manner; at this time, the dust removal cover 1 is set above the smelting furnace 12; the air duct connection port 4 is connected to the negative pressure extraction air duct.

[0037] During the smelting process, the smoke and dust in the dust removal housing 1 enter the rear wall cavity 2 through the dust removal suction groove 3, and then are sucked away by the air duct through the air duct connection port 4; Figure 4 and Figure 5 As shown in , at this time, the lower insert frame 8 extends into the rear wall cavity 2, and the coarse filter 10 in the lower insert frame 8 will coarsely filter the large particles of dust in the gas, and the filter material will adhere to the lower surface of the coarse filter 10; when the filter material is fully attached or at regular intervals, the automatic control switch is performed.

[0038] like Figure 5 As shown in , during switching, the telescopic drive cylinder 901 controls the upper insertion frame 7 to slowly insert into the rear wall cavity 2, and the lower insertion frame 8 maintains the filtering state. When the upper insertion frame 7 is fully inserted into the rear wall cavity 2, the lower insertion frame 8 is controlled to return to the self-cleaning outer chamber 9 to complete the handover.

[0039] When the lower plug-in frame 8 returns to the self-cleaning outer chamber 9, the inclined gate tongue 502 corresponding to the lower slot 6 automatically falls to close the lower slot 6; and during the movement of the lower plug-in frame 8 back to the self-cleaning outer chamber 9, the vertical shift block 903 corresponding to the lower plug-in frame 8 will be squeezed and contacted with the control swing arm 905, so that the control swing arm 905 drives the vertical rod 907 to deflect downward, and when the lower plug-in frame 8 returns to its original position, the impact rotating block 909 will contact the coarse filter 10 in the lower plug-in frame 8 under the squeezing of the vertical shift block 903; dustproof The motor 908 drives the impact block 909 to rotate. The side surface of the impact block 909 is provided with a protrusion, which can strike and vibrate the coarse filter 10, so that the particles and dust attached to the surface of the coarse filter 10 are shaken off. The dust-proof motor 908 automatically shuts down after working for a certain period of time. During the coarse filtering process of the upper plug-in frame 7, the lower plug-in frame 8 inside the self-cleaning outer chamber 9 and the particles and dust shaken off are in a static state for a long time, so that the floating dust in the self-cleaning outer chamber 9 can be statically dropped into the pull ash hopper 911 for collection. The same applies when the upper plug-in frame 7 needs to be retracted into the self-cleaning outer chamber 9 for self-cleaning.

[0040] In the process of the telescopic drive cylinder 901 controlling the upper insert frame 7 to be inserted into the rear wall cavity 2 for switching, the coarse filter 10 in the lower insert frame 8 is in a filtering state, and as the upper insert frame 7 is gradually inserted, the upper insert frame 7 will also hinder the airflow, and its obstruction effect gradually increases from small to large. When the upper insert frame 7 is fully inserted into the rear wall cavity 2, so that the upper insert frame 7 and the lower insert frame 8 are connected in series, the gas needs to pass through two groups of coarse filters 10 at the same time, and the airflow is most obstructed at this time; and in the process of the lower insert frame 8 being withdrawn to the self-cleaning outer chamber 9, due to the gradual removal of the lower insert frame 8, the coarse filter 10 in the upper insert frame 7 is retained to filter alone, and the obstruction effect on the airflow is gradually reduced from the maximum. Therefore, in the entire process of switching between the upper insert frame 7 and the lower insert frame 8, the obstruction of the airflow in the rear wall cavity 2 is from small to large, and then from large to small.

[0041] like Figure 2 As shown in FIG. 1 , during the switching process between the upper insert frame 7 and the lower insert frame 8, the active turntable 208 is driven by the motor at a constant speed to rotate, so that the turntable arm 209 lifts the right-angle lifting member 207 and drives the lifting top plate 203 to rise. During the process of the active turntable 208 rotating at a constant speed for one circle, the rising speed of the right-angle lifting member 207 and the lifting top plate 203 changes from slow to fast, and then from fast to slow. The reason is that the rotation of the turntable arm 209 is a circular motion, such as Figure 3As shown in , the turntable arm 209 rotates counterclockwise, and at the bottom of the circle, the turntable arm 209 is in a horizontal rightward displacement state. As it rotates, its upward drive distribution gradually increases. Until the turntable arm 209 rotates to the rightmost position, the turntable arm 209 is in an upward movement state, and the upward movement speed of the turntable arm 209 is the same as the rotational linear speed of the turntable arm 209; then as it rotates, the upward drive distribution of the turntable arm 209 gradually decreases; thereby, the rising speed of the right-angle lifting member 207 and the lifting top plate 203 changes from slow to fast, and then from fast to slow; variable speed control is achieved when the motor rotates at a constant speed, thereby avoiding the need for motor control equipment such as frequency converters and reducing equipment costs.

[0042] The rising speed of the lifting top plate 203 changes from slow to fast and then from fast to slow, which is the change of the air suction flow of the bellows 204, so that the air suction flow of the bellows 204 changes from small to large and then from large to small; and in the process of switching between the upper plug-in frame 7 and the lower plug-in frame 8, the obstruction of the airflow in the rear wall cavity 2 changes from small to large and then from large to small, which is consistent with the change, so that when the airflow in the rear wall cavity 2 is obstructed and the air pressure at the dust removal suction groove 3 is reduced, the side arc tube 201 can more appropriately supplement the air suction.

[0043] When the turntable arm 209 passes through the right-angle lifting member 207, the right-angle lifting member 207 loses the drive of the turntable arm 209. At this time, the corrugated bag 204 automatically contracts under the tension of the reset spring 205, so that the gas passes through the unidirectional beam cone 211 and is slowly discharged into the rear wall cavity 2.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
