Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smoke treatment equipment, in particular to a copper material production smoke treatment device. BACKGROUND

[0002] The smoke is generated during the smelting of copper material, and the core reason is that copper and related substances volatilize, oxidize or physically splash under high temperature environment, forming fine particles and diffusing into the air. Specifically, the melting point of copper is about 1083℃, and the high temperature during smelting will change part of the composition in the copper material: on the one hand, a small amount of copper will volatilize into copper vapor, and zinc, lead and other low-boiling-point impurities (such as zinc with a boiling point of only 907℃) contained in the copper material are more likely to volatilize in large quantities. These vapors quickly cool and condense into fine particles of solid copper or zinc when they enter the low-temperature air; on the other hand, copper and impurities will react with oxygen in the air under high temperature to generate oxides such as copper oxide and zinc oxide, which will float as solid small particles; in addition, the molten metal may splash due to stirring and boiling during smelting, and the fine metal droplets that splash out quickly solidify, which will also form smoke. If the copper material contains sulfide impurities, sulfur dioxide gas will also be generated in the oxidation reaction, and part of the gas will combine with metal particles to further form composite particles, further exacerbating the generation of smoke.

[0003] However, the prior art still has great deficiencies, such as: Most of the existing devices use single filter components, such as cloth bag dust removal. After a long time of use, the surface of the filter component is easy to accumulate dust and block, and it is difficult to alleviate the local dust accumulation through its own structure. Frequent shutdown and cleaning are required, which cannot meet the continuous production requirements of copper material smelting. SUMMARY

[0004] The purpose of the present application is to provide a copper material production smoke treatment device to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present application provides the following technical scheme: A copper material production smoke treatment device, comprising a support, a box body is fixedly arranged on the support, an air inlet and an air outlet are formed in the box body, a flower plate is fixedly arranged in the box body, the box body is divided into a clean air chamber and a dust removal chamber by the flower plate, a plurality of filter bags are fixedly arranged on the flower plate, the filter bags are supported on the flower plate by a frame, two rotating shafts are rotatably arranged in the dust removal chamber of the box body, chain wheels are fixedly arranged on the two rotating shafts, chains are sleeved on the chain wheels, filter plates are fixedly arranged on the chains, smoke enters the box body through the air inlet, is filtered for the first time by the filter plates, is filtered for the second time by the filter bags, and is then discharged through the air outlet. The box body is also provided with a first cleaning assembly and a second cleaning assembly for cleaning the filter bags and the filter plates, respectively.

[0006] Preferably, the first cleaning assembly comprises a gas tank fixed on the outer wall of the box, the gas tank is fixedly connected with a pulse valve, the pulse valve is fixedly connected with a solenoid valve, the solenoid valve is fixedly connected with a first blowing pipe, the first blowing pipe is arranged in the clean gas chamber and penetrates the box, and a plurality of venturi pipes are fixedly connected with the first blowing pipe, and the jet positions of the venturi pipes correspond to the openings of the filter bags.

[0007] Preferably, the second cleaning assembly comprises a second jet pipe fixed on the outer side of the box, the second jet pipe is fixedly connected with two branch pipes, the branch pipes are fixedly connected with a plurality of cleaning pipes, and the cleaning pipes penetrate the side wall of the box and are arranged to blow air flow towards the filter plate. One of the rotating shafts is fixedly provided with a worm gear, one of the branch pipes is fixedly provided with a volute, the volute is rotatably provided with a rotating shaft, a plurality of turbine blades are fixedly arranged on the rotating shaft, and a worm is fixedly arranged on the other end of the rotating shaft and engaged with the worm gear of the rotating shaft.

[0008] Preferably, a blower is fixedly arranged above the exhaust port.

[0009] Preferably, an air inlet pipe is fixedly connected with the air inlet, and the air inlet pipe is connected with the copper smelting equipment.

[0010] Preferably, an ash hopper is fixedly arranged below the box, and an ash discharge port is arranged at the bottom of the ash hopper.

[0011] Preferably, an observation window is arranged on the side wall of the box, and a sealing door is rotatably arranged at the position of the observation window.

[0012] Preferably, a maintenance platform is fixedly arranged on the support, and a guardrail and a ladder are fixedly arranged on the maintenance platform.

[0013] Compared with the prior art, the present application has the following advantages: 1. When the filter bag is cleaned, the high-pressure gas in the gas tank is sprayed to the filter bag through the blowing pipe and the venturi pipe, so that the filter bag is expanded and shaken to automatically shake off the dust; when the filter plate is cleaned, the air flow directly blows off the dust through the cleaning pipe, and at the same time, the air flow drives the turbine worm to rotate, so that the filter plate moves circularly, ensuring that each part can be cleaned. The dust is collected through the ash hopper and discharged through the ash discharge port, and the whole process does not need manual disassembly and washing, reducing the number of shutdown maintenance and manual input.

[0014] 2. The blower forms a negative pressure at the exhaust port, guiding the exhaust gas to flow along the path of "air inlet pipe -> filter plate -> filter bag -> clean gas chamber -> exhaust port", avoiding the dead angle caused by turbulent flow. The power for moving and cleaning the filter plate comes from the air flow itself, without the need for an additional motor, which not only reduces energy consumption, but also ensures stable operation and reduces the probability of failure.

[0015] 3. The two-stage filtration method of filtering large particle impurities with filter plates and filtering fine impurities with filter bags can effectively improve the precision of smoke dust purification. The filter plates move in a cycle with a chain, and the filter bags are stably fixed through a frame, ensuring that the filtering area is always fully utilized and avoiding the influence of local dust accumulation on efficiency. It can continuously process the smoke dust generated during copper smelting.

[0016] The working principle of the device is as follows: the copper smelting exhaust gas enters the box dust removal chamber through the inlet pipe and inlet, and flows upward under the negative pressure guidance of the air blower. First, it is intercepted by the circulating filter plate to block large particle impurities (primary filtration), and then it passes through the filter bag to block fine impurities (secondary filtration). The purified gas is discharged through the clean gas chamber and the exhaust port.

[0017] When cleaning, the first cleaning assembly blows the filter bag with high-pressure gas to make it shake and shake off the dust into the ash bucket. The second cleaning assembly directly blows off the dust on the filter plate with airflow, and at the same time, the airflow drives the worm gear linkage to move the filter plate in a cycle, realizing continuous cleaning. The dust is collected by the ash bucket and discharged through the ash discharge port. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0021] Please refer to Figures 1-7 The present application provides a technical solution: Embodiment one: The main structure of the copper material production smoke dust treatment device and the connection of each part are the basis for realizing the smoke dust purification function. The specific connection and action logic are as follows: The device takes the support 1 as the overall bearing foundation to provide stable support for the whole set of equipment. The box body 2 is directly installed on the support 1 as the core cavity of smoke dust treatment and keeps the spatial position stable relying on the support of the support 1.

[0022] Inside the box body 2, the flower plate 3 is horizontally arranged to divide the internal space of the box body 2 into two independent areas, the upper part is the clean gas chamber 201 and the lower part is the dust removal chamber 202. The filter bag 4 is vertically installed, the top end of which is connected and fixed with the flower plate 3, and the inside of the filter bag 4 is supported by the frame 5, which cooperates with the flower plate 3 and the inner wall of the box body 2 to limit the shape and position of the filter bag 4, so that the filter bag 4 is stably located in the communication path between the dust removal chamber 202 and the clean gas chamber 201, and the orderly progress of the waste gas filtration process is guaranteed.

[0023] The gas inlet 203 is opened on the box body 2, which is communicated with the gas inlet pipe 13 through the pipeline, and the waste gas generated by smelting is transported through the gas inlet pipe 13 and enters the dust removal chamber 202 of the box body 2 through the gas inlet 203; the exhaust port 204 is opened on the side wall of the box body 2 corresponding to the area of the clean gas chamber 201, which cooperates with the air blower 12, and when the air blower 12 operates, the gas flow negative pressure is formed in the box body 2, the gas purified by the filter bag 4 in the clean gas chamber 201 is extracted and discharged to the outside through the exhaust port 204.

[0024] The observation window 205 is opened on the side wall of the box body 2, and the sealing door 206 is installed at the observation window 205 through the hinge and other connecting parts. The sealing door 206 is closed during normal operation to block the gas leakage; when maintenance or observation of the internal situation is needed, the sealing door 206 can be opened, and the staff can check the state of the filter bag 4, filter plate 9 and other parts through the observation window 205.

[0025] The bottom of the box 2 is welded or connected with the hopper 14 by flange, etc. The hopper 14 is funnel-shaped. The dust intercepted by the filter bag 4 and the filter plate 9 in the dust removal chamber 202 falls naturally under the action of gravity and is collected in the hopper 14. The bottom of the hopper 14 is provided with a dust discharge port 15, which can be opened and closed by a valve. The dust discharge port 15 is opened regularly to discharge the collected dust.

[0026] A maintenance platform 16 is built at the position corresponding to the box 2 of the support 1 by welding, bolt connection or the like. The surface of the platform is paved with anti-skid plates. Guardrails 17 are installed at the edges of the platform to prevent personnel from falling. Ladders 18 are connected to the side of the platform. One end of the ladder 18 is fixed to the support 1 or the ground. The workers go up and down the maintenance platform 16 by means of the ladder 18 to maintain the components (such as solenoid valve 1003, air jet pipe, etc.) on the top and side wall of the box 2.

[0027] Flue dust filtering process The waste gas generated by smelting copper materials is transported through the inlet pipe 13 and enters the dust removal chamber 202 of the box 2 through the inlet 203. After entering the dust removal chamber 202, the waste gas directly contacts the filter plate 9. The movement of the filter plate 9 is controlled by the chain 8, the rotating shaft 6 and the chain wheel 7. Two rotating shafts 6 are installed in parallel on the box 2. A plurality of chain wheels 7 are fixed on the two rotating shafts 6. A plurality of chains 8 are sleeved on the chain wheels 7 to form a closed transmission structure. The filter plate 9 is fixed on the surface of the chain 8. When the rotating shaft 6 rotates, the chain wheel 7 rotates, driving the chain 8 to move in a cycle, and the filter plate 9 moves in a cycle synchronously with the chain 8.

[0028] When the waste gas contacts the filter plate 9 moving in a cycle, part of the waste gas passes through the gap between the filter plate 9 and the chain 8 and the channel formed by the filter plate 9 and continues to flow upwards in the dust removal chamber 202 due to the structural characteristics (such as porosity, surface adsorption layer, etc.) of the filter plate 9. The filter plate 9 in this embodiment can be selected by the operator according to the actual situation. The type of the filter plate 9 is not limited herein. The filter plate 9 is fixed by a filter frame arranged on the outside of the filter plate 9. The filter plate 9 can be completely fixed and supported on the chain 8. The impurities with large particle size in the waste gas are intercepted and adsorbed by the surface of the filter plate 9 to complete the primary filtration.

[0029] The waste gas preliminarily purified by the filter plate 9 flows upwards in the dust removal chamber 202 and contacts the filter bag 4. The top end of the filter bag 4 is connected to the flower plate 3, and the bottom end is naturally suspended or limited by the frame 5 to form a gas passage from the dust removal chamber 202 to the clean gas chamber 201. When the waste gas passes through the filter bag 4, fine impurities are intercepted by the filter bag 4 due to the fine filtering characteristics (such as fiber porosity, surface electrostatic adsorption, etc.) of the filter bag 4. The specific material of the filter bag 4 can be set by the designer according to the actual situation. The specific material of the filter bag 4 is not limited herein. Only the purified gas can pass through the filter bag 4 to enter the clean gas chamber 201 to complete the secondary filtration.

[0030] The clean air chamber 201 is a relatively closed space above the flower plate 3, and is in communication with the exhaust port 204. The blower 12 is installed on the top of the box body 2, and when the blower 12 is running, an air pressure difference is formed between the clean air chamber 201 and the external environment: the purified gas in the clean air chamber 201 is extracted from the clean air chamber 201 through the exhaust port 204 under the action of the air pressure difference and is directly discharged into the external environment.

[0031] In the whole process, the exhaust gas enters the dust removal chamber 202 through the air inlet pipe 13 and the air inlet 203, is filtered by the filter plate 9 for the first time and the filter bag 4 for the second time, and then the purified gas is discharged from the exhaust port 204 under the action of the blower 12. The components are connected by structure and matched by movement to realize the staged filtration and orderly purification of the smoke dust.

[0032] Embodiment two: In order to prevent the filter plate 9 and the filter bag 4 from affecting the filtering efficiency due to the surface dust, the device is provided with a first cleaning assembly and a second cleaning assembly for cleaning the filter bag 4 and the filter plate 9 respectively. The connection and operation mode of each assembly is as follows: The core power source of the first cleaning assembly is the gas storage tank 1001, which is connected with an external gas source (such as a gas pump) through a pipeline for storing high-pressure gas. The gas outlet of the gas storage tank 1001 is connected with the input end of the pulse valve 1002, and the output end of the pulse valve 1002 is connected with the electromagnetic valve 1003. Through the coordinated control of the pulse valve 1002 and the electromagnetic valve 1003, the blowing frequency and time of the high-pressure gas can be adjusted.

[0033] The output end of the electromagnetic valve 1003 is connected with the first blowing pipe 1004, one end of which is in communication with the electromagnetic valve 1003 and the other end of which penetrates through the side wall of the box body 2 and extends into the clean air chamber 201. A plurality of Venturi tubes 1005 are connected on the pipe section of the first blowing pipe 1004 in the clean air chamber 201, and the jet ports of the Venturi tubes 1005 correspond to the top openings of the filter bags 4 one by one.

[0034] When the filter bag 4 needs to be cleaned, the high-pressure gas flows out from the gas storage tank 1001, enters the first blowing pipe 1004 through the pulse valve 1002 and the electromagnetic valve 1003, and is directed to the filter bag 4 through the Venturi tube 1005. The high-pressure airflow makes the filter bag 4 instantaneously expand and then rapidly contract, generates a shaking, shakes off the dust adsorbed on the surface of the filter bag 4, and the dust falls to the ash hopper 14 at the bottom of the box body 2 under the action of gravity, thereby realizing the self-cleaning of the filter bag 4.

[0035] The gas source of the second cleaning assembly is connected to the second gas jet pipe 1101, which can supply gas continuously or intermittently according to actual needs. The output end of the second gas jet pipe 1101 is connected to two shunt pipes 1102, which divide the gas into two paths for delivery. The shunt pipes 1102 are symmetrically arranged at both ends of the filter plate 9 assembly. A plurality of cleaning pipes 1103 are connected to the shunt pipes 1102. The ends of the cleaning pipes 1103 away from the shunt pipes 1102 penetrate the side wall of the box 2 and extend into the dust removal chamber 202, with the jet direction directly facing the surface of the filter plate 9.

[0036] One of the shunt pipes 1102 is provided with a volute 1105. A rotating shaft 1106 is rotatably arranged inside the volute 1105. A plurality of turbine blades 1107 are fixed to the rotating shaft 1106. The turbine blades 1107 are located in the airflow passage inside the volute 1105. One end of the rotating shaft 1106 extends to the outside of the volute 1105, and a worm 1108 is fixed to the end. The worm 1108 is engaged with the worm gear 1104 on one of the rotating shafts 6. A plurality of supporting blocks are also arranged on the box 2 to support the rotating shaft 1106. When the gas enters the shunt pipe 1102 through the second gas jet pipe 1101, it is directly sprayed to the filter plate 9 moving in a cycle through the cleaning pipe 1103, blowing off the dust adsorbed on the surface of the filter plate 9, which falls into the ash hopper 14. At the same time, the gas enters the volute 1105, impacting the turbine blades 1107 to drive the rotating shaft 1106 to rotate. The rotating shaft 1106 drives the worm 1108 to rotate synchronously. The worm 1108 is engaged with the worm gear 1104 to drive the rotating shaft 6 and the sprocket 7 fixed to the rotating shaft 6 to rotate. The sprocket 7 drives the chain 8 to move in a cycle, so that the filter plate 9 continuously rotates with the chain 8.

[0037] Through the above cooperation, the filter plate 9 continuously passes through the jet area of the cleaning pipe 1103 during the cycle movement, achieving the cycle cleaning of the filter plate 9. In this process, the pressure of the airflow is sufficient to drive the turbine blades 1107 to rotate, while meeting the requirement of blowing off the dust on the surface of the filter plate 9.

[0038] Working principle: in the process of using, the copper smelting waste gas enters the dust removal chamber 202 of the box body 2 through the inlet pipe 13 and the inlet 203, and flows upwards along the dust removal chamber 202 under the negative pressure formed by the air blower 12 (at the exhaust port 204). The waste gas first contacts the circulating filter plate 9, which moves synchronously with the chain 8, the sprocket 7 and the rotating shaft 6, intercepts and adsorbs the impurities with large particle size in the waste gas, and part of the waste gas passes through the gap between the side and the bottom of the filter plate 9 and continues to flow upwards, completing the primary filtration. The waste gas purified by the filter plate 9 passes through the filter bag 4 (supported by the frame 5 and fixed on the flower plate 3, in the communication path between the dust removal chamber 202 and the clean gas chamber 201), the filter bag 4 intercepts fine impurities, and the purified gas enters the clean gas chamber 201, completing the secondary filtration. Finally, the purified gas in the clean gas chamber 201 is discharged to the outside through the exhaust port 204 under the negative pressure of the air blower 12.

[0039] The cleaning principle is that the filter bag 4 is cleaned by the first cleaning assembly: the high-pressure gas stored in the gas storage tank 1001 is controlled by the pulse valve 1002 and the electromagnetic valve 1003 to blow at a certain rhythm, and then is delivered to the venturi tube 1005 through the first blowing pipe 1004. The venturi tube 1005 directs the gas to the opening of the filter bag 4, so that the filter bag 4 expands and shakes instantaneously, and the dust adsorbed on the surface is shaken off to the ash bucket 14. The filter plate 9 is cleaned by the second cleaning assembly: the gas source outside is divided into two paths through the second gas blowing pipe 1101 and the shunt pipe 1102. One path of the gas is blown to the circulating filter plate 9 through the cleaning pipe 1103, and the dust on the surface of the filter plate 9 is directly blown to the ash bucket 14. The other path of the gas enters the volute 1105, impacts the turbine blade 1107 to drive the rotating shaft 1106 and the worm 1108 to rotate, the worm 1108 meshes with the worm gear 1104 on the rotating shaft 6 (increases the torque), drives the rotating shaft 6 and the sprocket 7 to rotate, and then drives the chain 8 and the filter plate 9 to move circularly, so that the filter plate 9 continuously passes through the gas blowing area of the cleaning pipe 1103 in the moving process, realizing the circular cleaning.

[0040] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
