Description

Technical Field

[0001] This utility model relates to the field of copper processing and casting technology, specifically a dust collector for copper processing and casting. Background Technology

[0002] During the copper smelting and casting process, dust is generated and diffused into the air. This dust pollutes the environment and also affects the health of workers. To solve these problems, dust collectors are usually installed at the processing site to remove and filter dust from areas where dust is easily generated.

[0003] However, existing dust collectors have the following shortcomings when used for dust removal in copper processing and casting: 1. The simple method of dust collection using the dust collector and its internal filter screen inevitably results in a significant amount of fine dust remaining after the filtered gas is discharged. There is a lack of a further purification mechanism for residual fine dust after filtration, leading to poor dust removal efficiency; 2. As filtration progresses, filter elements inevitably become clogged, requiring the dust collection and filtration process to be stopped for cleaning of the filter elements and dust particles. There is a lack of a mechanism for personnel to clean the filter without shutting down the machine, which greatly reduces work continuity and efficiency. Therefore, this application proposes a dust collector for copper processing and casting to solve the above-mentioned problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1 to 4 As shown in this embodiment, a dust collector for copper processing and casting includes:

[0032] Water tank 1 has a drain valve fixed to its bottom left side and an exhaust pipe fixed to its top right side. It is filled with water.

[0033] Rectangular box 2 is fixedly installed on top of water tank 1;

[0034] The suction and air delivery assembly is connected and fixed to the bottom of the rectangular box 2; the suction and air delivery assembly is used to provide suction force to the rectangular box 2 and discharge the suction gas into the water in the water tank 1.

[0035] The ventilation box 3 consists of two sets. Both ventilation boxes 3 have a conical bottom and an integral circular flow passage. The two circular flow passages are respectively connected and fixed to the top two sides of the rectangular box 2. When the rectangular box 2 generates suction force inside, it draws suction from the connected ventilation box 3.

[0036] An adaptive directional ventilation assembly is connected and fixed between the tops of two ventilation boxes 3 on adjacent sides;

[0037] The filter and slag collection assembly consists of two sets, each installed in its corresponding vent box 3;

[0038] An automatic switching component is installed on the rectangular box 2 and cooperates with two circular flow passages. The automatic switching component is used to switch between connection and closure between the two ventilation boxes 3 at regular intervals, so as to switch the suction inside the two ventilation boxes 3 and ensure that there is always suction force on one of the ventilation boxes 3, forming an alternating non-stop application effect. The adaptive direction-changing ventilation component is used to adaptively change the suction air intake direction when the two ventilation boxes 3 are alternately suctioned, and to perform dust suction work on the outside. The filter and slag collection component is used to filter, intercept and collect dust impurities in advance when dust gas is drawn into the corresponding ventilation box 3. After the gas enters the rectangular box 2 and is sucked and blown into the water, the residual dust is adsorbed by the water.

[0039] In this embodiment, four support rods are fixedly connected in a rectangular shape between the top of the water tank 1 and the bottom of the rectangular box 2 for support.

[0040] Furthermore, such as Figure 1 and 2 As shown, the suction and air supply assembly includes a powerful fan 101 and an air vent 102. The top of the powerful fan 101 is a suction port and is connected and fixed to the bottom of the rectangular box 2. The bottom of the powerful fan 101 is an air outlet. The top of the air vent 102 is set as a cover-shaped structure and is connected and fixed to the bottom of the powerful fan 101. The bottom end of the air vent 102 extends into the water tank 1. Multiple air outlets located in the water are opened on all four sides of the air vent 102.

[0041] In this embodiment, the powerful fan 101, the vent pipe 102 and the air outlet work together to draw gas into the rectangular box 2 and blow the drawn gas into the vent pipe 102. The gas is discharged into the water through the bottom of the vent pipe 102 and multiple air outlets. The water is used to adsorb and purify the residual dust in the gas. The adsorbed and purified gas floats up and is discharged through the exhaust pipe.

[0042] Furthermore, such as Figure 1 and 2 As shown, the adaptive reversible ventilation assembly includes two one-way valves 4 and a three-way pipe 401. The two one-way valves 4 have outlets on opposite sides and are respectively connected and fixed to the top of the side of the two ventilation boxes 3 that are close to each other. The three-way pipe 401 is connected and fixed between the two one-way valves 4. The top end of the three-way pipe 401 is connected and fixed with a dust suction hose for connecting to the dust suction hood set outside the copper processing dust generation area.

[0043] In this implementation scheme, by using two one-way valves 4, a three-way pipe 401 and a suction hose, when a suction force is generated in the venting box 3, the corresponding one-way valve 4 draws into the three-way pipe 401. The three-way pipe 401, through the suction hose and the connected external dust hood, performs dust removal work on the copper processing dust-generating area. Since the two venting boxes 3 are used alternately for suction, and with the two one-way valves 4 having their opposing sides as outlets, the system achieves the effect of adaptively changing the direction of ventilation into the two venting boxes 3 when suction is performed sequentially in the two venting boxes 3.

[0044] Furthermore, such as Figure 1 and 2 As shown, the filter and slag collection assembly includes a stainless steel filter cartridge 301, a connecting rod 302, a round cover 303, and a U-shaped handle. The stainless steel filter cartridge 301 is installed in the corresponding vent box 3. The top of the stainless steel filter cartridge 301 is set as an opening. The top of the outer side of the stainless steel filter cartridge 301 is set as an outward expansion structure and is in movable contact with the inner side of the corresponding vent box 3. The stainless steel filter cartridge 301 is located below the corresponding one-way valve 4. The round cover 303 is sleeved on the outer side of the top of the corresponding vent box 3. The top and bottom ends of the connecting rod 302 are fixedly connected to the inner wall of the top of the corresponding round cover 303 and the inner wall of the bottom of the stainless steel filter cartridge 301, respectively. The U-shaped handle is fixedly connected to the top of the corresponding round cover 303. A breathable filter cloth is bonded and fixed to the inner side of the stainless steel filter cartridge 301. A sealing gasket that is in movable contact with the top of the corresponding vent box 3 is bonded and fixed to the inner wall of the top of the round cover 303.

[0045] In this embodiment, the stainless steel filter cartridge 301, connecting rod 302, round cover 303, and U-shaped handle work together to pre-filter and intercept dust particles and impurities in the dust gas when it is drawn into the ventilation box 3. The filtered gas is then drawn into the rectangular box 2, and then drawn in by the powerful fan 101 and blown into the water through the ventilation pipe 102 to adsorb micro-dust. By using the synergistic method of pre-filtering dust particles and impurities and further adsorbing and purifying micro-dust, the effect of effective dust removal is achieved, reducing the phenomenon of residual micro-dust in the discharged gas polluting the environment and harming the health of personnel.

[0046] Furthermore, the round cover 303 is movably fitted onto the outer side of the top of the corresponding vent box 3.

[0047] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, the self-switching opening and closing assembly includes a sealing plate 201, a U-shaped guide seat 202, a movable seat 203, an electric telescopic rod 205, a PLC controller 207, and an audible and visual alarm light 208. The U-shaped guide seat 202 is fixedly connected to the inner wall of the top of the rectangular box 2. The sealing plate 201 is slidably fitted inside the U-shaped guide seat 202 and makes sealing contact with the inner wall of the top of the rectangular box 2. The sealing plate 201 is located at the bottom of the circular flow passage on the left side and is offset from the bottom left side of the circular flow passage on the right side. A rectangular through hole 206 is provided on the top of the rectangular box 2, and the movable seat 203 is located in the rectangular through hole 206. The electric telescopic rod 205 is fixedly installed on the top of the rectangular box 2 and the extended end of the electric telescopic rod 205 is fixedly connected to the right side of the movable seat 203. The PLC controller 207 is fixedly installed on the left side of the ventilation box 3 on the right side. The audible and visual alarm light 208 is fixedly and electrically connected to the left side of the PLC controller 207. Tactile switches 204 are fixedly connected to the inner walls on both sides of the rectangular through hole 206. The movable seat 203 is located between the two tactile switches 204. The tactile switches 204 and the electric telescopic rod 205 are both electrically connected to the PLC controller 207.

[0048] In this embodiment, a sealing rubber is bonded and fixed to the top of the sealing plate 201, and the top of the sealing rubber is in active contact with the top inner wall of the rectangular box 2 and the bottom of the circular flow passage.

[0049] In this implementation scheme, the sealing plate 201, U-shaped guide seat 202, movable seat 203, electric telescopic rod 205, PLC controller 207, tactile switch 204, and audible and visual alarm light 208 work together. The PLC controller 207 is pre-set to control the electric telescopic rod 205 to start sequentially in both forward and reverse directions, and is set to activate the audible and visual alarm light 208 each time it starts. Initially, the ventilation box 3 on the right side is connected to the rectangular box 2. When the first set cleaning time is reached, the PLC controller 207 controls the electric telescopic rod 205 to start in reverse, causing it to drive the movable seat 203 to move to the right. The sealing plate 201 moves to the right, sealing the right-side vent box 3 and unsealing the left-side vent box 3, switching to suction into the left-side vent box 3 and stopping suction into the right-side vent box 3. When the moving seat 203 moves to the right and presses the right-side tactile switch 204, the PLC controller 207 detects a voltage signal and identifies it as a triggered state. It then controls the electric telescopic rod 205 to close automatically and activates the audible and visual alarm light 208 to remind personnel to clean. At this time, personnel can then move the right-side round cover 303 upwards to allow it to pass through the right-side connecting rod 3. 02. Move the stainless steel filter cartridge 301 on the right upwards to clean the impurities collected inside. After cleaning, insert the stainless steel filter cartridge 301 into the vent box 3 on the right, and cover the top of the vent box 3 with the round cover 303. When the next cleaning time is reached, the PLC controller 207 switches to controlling the electric telescopic rod 205 to start forward and controls the audible and visual alarm light 208 to turn on again. This causes the sealing plate 201 to move back to the left via the moving base 203, sealing the vent box 3 on the left and unsealing the vent box 3 on the right. The system then switches back to using the vent box 3 on the right for suction filtration. At this point, the stainless steel filter cartridge 301 on the left and the impurities collected by the filter can be removed and cleaned in the same way as described above. When the next cleaning time is reached, the control plate 201 is moved to the right again, switching back to sealing the vent box 3 on the right and unsealing the vent box 3 on the left. This achieves the effect of automatically switching the ventilation and filtration application on both sides at a timed interval, and reminding personnel to clean the filter elements and impurities after use. This forms an alternating filtration and cleaning application effect on both sides. By using the alternating filtration and cleaning application on both sides, it is convenient to carry out cleaning and slag removal work without affecting the dust collection and filtration purification work, thereby improving work continuity and improving work efficiency.

[0050] It should be noted that: polypropylene filter cloth is preferred for breathable filter cloth, which has good chemical stability and breathability, high porosity and uniform pore size, and can effectively intercept dust particles. This material is a conventional application material in the fields of industrial dust removal and water filtration, and is widely used in various particulate filtration systems or equipment. Specific specifications (such as density and filtration accuracy) can be selected according to the actual working conditions. By conventionally configuring breathable filter cloth and selecting the appropriate specifications according to the application, it is a mature and well-known conventional technical means in this field, and will not be elaborated further.

[0051] The powerful blower 101 preferably adopts the Shenghong EHS-929 vortex blower, which has strong suction and blowing force to meet the needs of dust collection and downdraft air supply; the PLC controller 207 preferably adopts the Siemens S7-200SMART programmable controller with programmable time control function. Through programming, the time and interval of the electric telescopic rod 205 to start alternately in reverse and forward directions, as well as the opening and closing time of the audible and visual alarm light 208 can be set. When the set time is reached, the electric telescopic rod 205 is automatically started accordingly, thereby realizing the time control function of the corresponding steps. The above operations are all conventional applications of the programmable controller and will not be described in detail here.

[0052] Regarding the connection method of tactile switch 204, its two ends are respectively connected to the input point (such as I0.0) of PLC controller 207 and the negative terminal of external power supply through wires. When tactile switch 204 is pressed and triggered to close, causing the circuit to be connected, the input point of PLC controller 207 can detect the voltage signal and identify it as a "trigger state" so as to perform the shutdown control work according to the programming program.

[0053] Furthermore, the electrical connection between the electric telescopic rod 205 and the PLC controller 207 is achieved through wires and a servo driver. The preferred servo driver is a Siemens V90 servo driver, which is a commonly used driver for controlling motors and electric actuators in conjunction with Siemens programmable controllers, thus meeting the direct control requirements of the programmable controller over the electric telescopic rod 205. This method of establishing an electrical connection under the control of the PLC controller 207 through direct wire connection is a mature and well-known technology for conventional wired control of the controller, and will not be described in detail here.

[0054] Regarding power supply, given that the copper processing and casting site is a copper processing production site with complete and sufficient mains power supply facilities, all electrical components of this device are connected to the mains power supply. Through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure), they are connected to the power input interfaces of each device to form a complete and stable power supply circuit. This power supply scheme conforms to the conventional power distribution standards for industrial equipment and is a mature and well-known technical means, which will not be elaborated here.

[0055] This embodiment effectively removes dust by pre-filtering dust particles and using water to further adsorb and purify micro-dust. This reduces the amount of residual micro-dust in the exhaust gas, which pollutes the environment and harms human health, thus improving dust removal efficiency. It also allows for automatic, timed switching between the two sides for alternating ventilation and filtration, reminding personnel to clean the filters and impurities after use. This creates an alternating filtration and cleaning effect, allowing for uninterrupted cleaning and slag removal without affecting the dust collection and filtration process, thereby improving work continuity and efficiency.

[0056] The usage method of this embodiment is as follows: When using the dust collector for copper processing and casting, the suction hose is connected to the dust collection hood set at the dust-generating area of ​​copper processing. The powerful fan 101 is started to draw suction from the inside of the rectangular box 2. When suction force is generated inside the rectangular box 2, it draws suction from the ventilation box 3 connected to the right side. The ventilation box 3 on the right side draws suction from the three-way pipe 401 through the one-way valve 4 on the right side. The three-way pipe 401, through the suction hose and the connected external dust collection hood, performs dust collection work at the dust-generating area of ​​copper processing, so that the dust gas generated by copper processing and casting is sequentially drawn into the ventilation box 3 on the right side through the suction hose, the three-way pipe 401 and the one-way valve 4 on the right side. At the same time, the stainless steel filter cartridge 301 and the breathable filter cloth on the right side pre-filter, intercept and collect dust particles and impurities in the dust gas. The filtered gas is drawn into the rectangular box 2, and then drawn by the powerful fan 101 and blown into the water through the ventilation pipe 102 to adsorb the micro dust. The adsorbed and purified gas floats up and is discharged through the exhaust pipe. This achieves the effect of dust suction, filtration and collection, and further adsorption and purification of residual micro dust in the gas before discharge. By using the synergistic method of pre-filtering dust particles and impurities and further adsorbing and purifying micro dust, the dust removal effect is achieved, reducing the phenomenon of residual micro dust in the discharged gas polluting the environment and harming the health of personnel, and improving the dust removal effect.

[0057] The PLC controller 207 is pre-set to control the electric telescopic rod 205 to start sequentially in both forward and reverse directions, and to activate the audible and visual alarm 208 upon each start. Initially, the right-side ventilation box 3 and the rectangular box 2 are connected. When the first set cleaning time is reached, the PLC controller 207 controls the electric telescopic rod 205 to start in reverse, driving the moving base 203 to move to the right. The moving base 203 drives the sealing plate 201 to move to the right, sealing the right-side ventilation box 3 and unsealing the left-side ventilation box 3, switching to suction from the left-side ventilation box 3 to the right-side ventilation box 3, while stopping suction from the right-side ventilation box 3. The suction process then switches to drawing in dusty gas through the one-way valve 4 on the left and pre-filtering dust particles using the filter element on the left. When the moving seat 203 moves to the right and presses the tactile switch 204 on the right, the tactile switch 204 is activated. This triggers the PLC controller 207 to detect a voltage signal, automatically closing the electric telescopic rod 205 and activating the audible and visual alarm 208 to remind personnel to clean. At this point, personnel can move the right-side circular cover 303 upwards, causing it to move the right-side stainless steel filter cartridge 3 via the connecting rod 302. 01. Move upwards to clean the impurities collected by the filter inside. After cleaning, insert the stainless steel filter cartridge 301 on the right into the vent box 3 on the right, and cover the top of the vent box 3 on the right with the round cover 303. When the next cleaning time is reached, the PLC controller 207 switches to controlling the electric telescopic rod 205 to start forward and controls the audible and visual alarm light 208 to turn on again. This causes the sealing plate 201 to move back to the left via the moving base 203, sealing the vent box 3 on the left and unsealing the vent box 3 on the right. The system then switches back to using the vent box 3 on the right for suction filtration. At this point, the above-mentioned... In the same way, the stainless steel filter cartridge 301 on the left and the impurities collected by the filter are removed and cleaned. When the next cleaning time is reached, the control plate 201 moves to the right again, switching back to sealing the vent box 3 on the right and unsealing the vent box 3 on the left. This achieves the effect of automatically switching the ventilation and filtration application on both sides at a timed interval, and reminding personnel to clean the filter components and impurities after use. This creates an alternating filtration and cleaning application effect on both sides. By using the alternating filtration and cleaning application on both sides, it is convenient to assist personnel in cleaning and removing slag without stopping the machine, without affecting the dust collection and filtration purification work, thereby improving work continuity and thus improving work efficiency.

[0060] This embodiment facilitates the screwing and threaded fixing of the round cover 303. Compared with a simple movable cover, the application stability of the round cover 303 is further improved by using the threaded connection method.

[0061] The method of use in this embodiment is as follows: The difference from the first embodiment is that it also has the following functions: By using the set external thread and internal thread to cooperate, and by using the meshing method of the external thread and the corresponding internal thread, the effect of conveniently screwing the round cover 303 into place and screwing it into place can be achieved. Compared with the simple movable cover, the application stability of the round cover 303 is further improved by using the screw connection method.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
