Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slag dust removal, in particular to a slag treatment and dust removal equipment. BACKGROUND

[0002] Slag is a product formed by the reaction of gangue, impurities in ore and molten metal or sulfur, phosphorus, silicon, etc. due to the addition of flux (such as limestone, dolomite, quartzite, etc.) in the pyrometallurgical process, usually in the form of silicate, oxide, sulfide, phosphate or sulfate, etc. After the generation of slag, it needs to be treated and recycled, etc.

[0003] In the process of slag treatment, the dust generated needs to be cleaned to ensure job safety and environmental protection.

[0004] In the prior art, a bag dust removal equipment is usually used for dust removal operation, and the bag dust removal equipment usually starts the suction equipment to guide the dust generated in the process of slag treatment into the dust removal box with multiple groups of cylindrical bags, and simultaneously starts the exhaust equipment to extract the gas. In the process of extraction, the dust in the gas is separated from the gas due to the blockage of the bag. After separation, the larger dust is discharged from the discharge port, and the smaller dust is adsorbed on the bag. Therefore, after a long time of use, a high-pressure air pump is started to spray air into the inside of the cylindrical bag to clean the dust on the bag.

[0005] However, in the prior art, only the high-pressure air pump is used for dust removal when cleaning the bag. Such dust removal effect is single, and if the parameters of the air flow (such as pressure, flow, blowing time, etc.) are not properly set, or the material, structure, arrangement of the bag are affected, it may cause uneven dust removal, and the dust attached to part of the bag cannot be effectively removed.

[0031] As Figures 1-5 shown, the present application provides a slag treatment dust removal equipment, comprising a support 1, which is provided with a dust removal assembly 2 for dust removal operation of the slag, specifically:

[0032] The dust removal assembly 2 comprises a dust removal box 22 fixedly installed on the support 1, which is provided with an air inlet pipe 27 connectable with the output end of an external dust collection device, and the input end of the dust collection device can suck in the dust generated during the slag treatment process;

[0033] The dust removal box 22 is fixedly installed with a partition plate 221, and a plurality of through holes (not shown in the figure) are formed in the partition plate 221, and a cloth bag 25 is arranged at the through holes;

[0034] It should be noted that the cloth bag 25 has two groups of brims (as Figure 4 , the through hole is clamped between the two groups of brims during installation to install it;

[0035] Referring to Figure 5 , a skeleton 26 is inserted into the cloth bag 25, which is welded by a plurality of steel bars 261 and steel rings 262 to limit the cloth bag 25, so as to avoid that the filtered gas causes large deviation of the cloth bag 25 during filtration, and a discharging hopper 28 is arranged at the bottom of the dust removal box 22 to facilitate the discharge of large dust after filtration;

[0036] The exhaust box 21 is fixedly installed on the partition plate 221, a plurality of cover plates 23 are arranged on the exhaust box 21 to close the exhaust box 21, and an air outlet 24 is formed in the exhaust box 21, the air outlet 24 is provided with an exhaust pipe 3, and a fan 32 is arranged at the end of the exhaust pipe 3 away from the air outlet 24, the input end of the fan 32 is connected with the exhaust pipe 3, and the output end of the fan 32 is provided with an air outlet pipe 31 to facilitate the discharge of the filtered gas;

[0037] Meanwhile, a dust cleaning assembly 4 is arranged on the dust removal assembly 2, which is used for dust cleaning operation of the cloth bag 25;

[0038] As Figures 2-3 shown, the dust cleaning assembly 4 comprises a mounting frame 401 installed on the dust removal box 22, and a high-pressure air pump 41 is fixedly installed on the mounting frame 401, the output end of the high-pressure air pump 41 is provided with a plurality of shunt pipes 42, and the shunt pipes 42 are provided with a plurality of nozzles 43 corresponding to the through holes;

[0039] Further, under the driving of the high-pressure air pump 41, the gas is sprayed into the skeleton 26 through the nozzles 43 to impact the cloth bag 25, so as to clean the dust attached to the cloth bag 25;

[0040] At the same time, the dust removal assembly 2 is provided with an auxiliary assembly 5 for assisting the cleaning of the cloth bag 25.

[0041] As shown in Figures 5-6 The auxiliary assembly 5 includes a fixed plate 52 fixedly installed on the steel ring 262 of the framework 26, a rotating rod (not shown in the figure) is rotatably installed on the fixed plate 52, the bottom of the rotating rod extends out of the bottom of the fixed plate 52, and a half gear 54 is fixedly sleeved on the bottom of the rotating rod, the half gear 54 has a plurality of clamping teeth, and an oval ring 53 is slidingly arranged at the bottom of the fixed plate 52, the inner ring of the oval ring 53 is provided with two sets of comb tooth groups 55, and the two sets of comb tooth groups 55 are oppositely arranged.

[0042] In the initial state, the clamping teeth are engaged with one of the two sets of comb tooth groups 55, when the rotating rod is rotated under the action of external force, the half gear 54 is rotated, thereby continuously engaging and disengaging the half gear 54 with the two sets of comb tooth groups 55, thereby driving the oval ring 53 to reciprocatingly slide on the fixed plate 52.

[0043] It should be noted that the oval ring 53 has two sets of extension blocks (not labeled in the figure), two sets of push blocks 56 are fixedly installed on the two sets of extension blocks, and the two sets of push blocks 56 are located outside the steel ring 262 and abut against the inner surface of the cloth bag 25, and the push blocks 56 extend to the lower end of the framework 26, thereby synchronously driving the two sets of extension blocks to reciprocatingly move when the oval ring 53 reciprocatingly moves, thereby vibrating the cloth bag 25.

[0044] At the same time, two sets of fans 51 are fixedly sleeved on the rotating rod, the two sets of fans 51 are oppositely arranged, so that the fan blades of the fans 51 are opposite, thereby the fan blades of the fans 51 can be impacted by the flow of air during dust cleaning or filtration, thereby driving the rotating rod to rotate, thereby driving the oval ring 53 to reciprocatingly move, that is, the cloth bag 25 can be vibrated during dust cleaning or filtration, and the cloth bag 25 can be vibrated during filtration, which can reduce the adhesion of dust to the surface of the cloth bag 25 during filtration, thereby prolonging the cleaning period of the cloth bag 25.

[0045] In summary, during use, the dust is sucked into the dust removal box 22 through the air inlet pipe 27, and the fan 32 is turned on, so that the gas in the dust removal box 22 can be filtered by the plurality of cloth bags 25 and discharged through the exhaust box 21, and in the process of the gas entering the exhaust box 21 from the cloth bag 25, the lower fan 51 is driven to rotate, thereby driving the auxiliary assembly 5 to start, thereby vibrating the cloth bag 25, so that the filtered dust does not adhere too much to the surface of the cloth bag 25, thereby prolonging the cleaning period of the cloth bag 25.

[0046] When the cloth bag 25 needs to be cleaned after a long time of use, the ash removal assembly 4 is started, high-pressure gas is sprayed into the cloth bag 25, the high-pressure gas contacts the fan 51 above, the auxiliary assembly 5 is started again, and the cloth bag 25 is vibrated, so that the ash removal effect is improved.

[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
