Description
Technical Field
[0001] This utility model relates to the field of copper rod smelting and casting, and in particular to a dust control device for copper rod smelting and casting. Background Technology
[0002] Dust control devices are designed to address the harmful fumes and gases generated during copper rod production. Their purpose is to ensure a clean environment and reduce air pollution during production. Common dust control equipment includes bag filters and cyclone dust collectors.
[0003] Baghouse dust collectors, with their high dust removal efficiency and strong adaptability, have become widely used dust removal equipment in the copper rod smelting and casting industry. Their working principle involves introducing harmful fumes and gases generated during copper rod production through the inlet pipe of the dust collector. A fan located near the outlet pipe guides the fumes into the baghouse dust collector, where solid particles are captured and accumulated on the surface of the internal filter screen. The purified air is then discharged through the exhaust pipe, while the filtered solid particles accumulate on the filter screen or fall into the dust discharge pipe and are discharged, thus achieving gas-solid separation. However, with increased usage time, a large amount of dust will adhere to the filter screen, leading to increased filter screen resistance, reduced ventilation efficiency, and decreased dust removal effect. Regular replacement or cleaning of the filter screen is usually necessary. In reality, this typically requires stopping the entire dust removal system, disassembling, cleaning, or replacing each filter screen inside the baghouse dust collector, and then reinstalling them to resume operation. This process is not only cumbersome but also consumes a significant amount of time and labor, reducing the dust removal efficiency of the baghouse dust collector and also decreasing the production efficiency of copper rods. Utility Model Content
[0004] The technical problem this invention aims to solve is that as usage time increases, a large amount of dust adheres to the filter screen, leading to increased resistance, reduced ventilation efficiency, and decreased dust removal effect. Regular replacement or cleaning of the filter screen is usually necessary. However, in practice, this typically requires stopping the entire dust removal system, disassembling, cleaning, or replacing each filter screen inside the baghouse dust collector, and then reinstalling them to resume operation. This process is not only cumbersome but also consumes a significant amount of time and labor, reducing the dust removal efficiency of the baghouse dust collector and also decreasing the production efficiency of copper rods.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a dust control device for copper rod smelting and casting, including a bag filter, an air inlet pipe on one side of the bag filter, an air outlet pipe on the top of the bag filter, a dust discharge pipe at the bottom of the bag filter, and an easy-to-clean device inside the bag filter. When it is necessary to clean or replace the filter screen inside the bag filter, the easy-to-clean device can activate an electric telescopic rod to drive the sliding frame to slide back and forth alternately in the rectangular hole, so that the filter screens inside both ends of the sliding frame can be used alternately. When one filter screen is in use, the other will be exposed on the outer surface of the bag filter, which is convenient for cleaning and replacement.
[0006] The effects achieved by the above components are as follows: Baghouse dust collectors, with their high dust removal efficiency and strong adaptability, have become widely used dust removal equipment in the copper rod smelting and casting industry. Their working principle involves introducing harmful fumes and gases generated during copper rod production through the inlet pipe of the dust collector. A fan located near the outlet pipe guides the gases into the interior of the baghouse dust collector. Solid particles in the gas are captured by the internal filter screen and accumulate on its surface. The purified air is discharged through the exhaust pipe, while the filtered solid particles accumulate on the filter screen or fall into the dust discharge pipe and are discharged, thus achieving gas-solid separation. After the filter screen has been used for a period of time, a cleaning device can be activated to slide out the used filter screen. A spare filter screen is then moved into the baghouse dust collector for continued filtration. The surface of the slid-out filter screen is then cleaned and replaced. This reduces the number of disassembly and replacement steps, improves the dust removal efficiency of the baghouse dust collector, reduces labor costs, and eliminates the need for prolonged shutdowns of the copper rod production line, thereby increasing production efficiency.
[0007] Preferably, the easy-cleaning device includes a sliding frame, a rectangular hole in the inner wall of the bag filter, the sliding frame being slidably installed in the inner wall of the rectangular hole, and rectangular grooves in the inner walls at both ends of the bag filter; two filter screens, wherein the filter screens are inserted into the rectangular grooves and the inner wall of the sliding frame, and a quick-release mechanism is provided between one side of the filter screen and the inner wall of the rectangular groove; a bracket, wherein one side of the bracket is fixedly installed on one side of the bag filter; and an electric telescopic rod, wherein one end of the electric telescopic rod is fixedly installed on one side of the bracket, and the output end is fixedly installed on one side of the sliding frame.
[0008] The aforementioned components achieve the following effect: By incorporating a convenient cleaning device, when using a baghouse dust collector to remove dust and gas generated during the copper rod production process, one end of the matching hood is connected to the inlet pipe, and the outlet pipe is connected to the subsequent processing equipment. During dust removal, the fan on the baghouse dust collector is activated to guide the dust and gas entering the inlet into the baghouse dust collector, where it is filtered through the filter screen inside one end of the sliding frame. The solid particles are intercepted and filtered out, and the filtered gas is discharged through the outlet pipe. Some of the intercepted solid particles adhere to the filter screen, while the rest fall into the outlet. In the dust pipe, the dust discharge pipe can be opened periodically to discharge solid particles. After the filter screen has been used for a period of time, the bag filter can be turned off first, and then the electric telescopic rod can be started to drive the sliding frame to slide in the rectangular hole, so that one end of the used filter screen slides out, while the other end slides into the interior of the bag filter for continued filtration. After replacement, the bag filter can be turned on to continue filtration. At this time, the slid-out filter screen can be cleaned, or it can be removed through the quick-release mechanism for easy replacement. This can reduce the number of disassembly and replacement steps, improve the dust removal efficiency of the bag filter, reduce labor costs, and at the same time, it does not require long-term shutdown of the copper rod production line, thus improving production efficiency.
[0009] Preferably, the outer surface of the output rod of the electric telescopic rod is symmetrically fixed with reinforcing rods, and one side of the reinforcing rod is fixedly installed on one side of the sliding frame.
[0010] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the electric telescopic rod and one side of the sliding frame can be increased, making the connection more secure and stable, and less prone to breakage or damage.
[0011] Preferably, the longitudinal section of the filter screen is trapezoidal, and the area of the end of the filter screen near the air intake pipe is larger than the area of the other end.
[0012] The effect achieved by the above components is as follows: by setting the filter screen into a conical shape, the gas generated during the copper rod production process can pass through the inclined surface of the filter screen, and the filtered solid particles will be carried by the gas to the middle position of the bottom of the filter screen. This reduces the probability of solid particles clogging the filter holes on the inclined surface of the filter screen and improves the filtration efficiency of the filter screen.
[0013] Preferably, sealing blocks are symmetrically fixedly installed on both sides of the sliding frame, and one side of the sealing block abuts against the inner wall of the rectangular hole.
[0014] The effect achieved by the above components is that by setting the sealing block, the gaps between the two sides of the sliding frame and the rectangular hole can be sealed and blocked, preventing gas from escaping from the gaps and achieving a sealing effect.
[0015] Preferably, the quick-release mechanism includes two rotating rods, one end of which is rotatably mounted on one side of the filter screen, and the inner wall of the rectangular groove is symmetrically provided with slots, and one end of the rotating rod is inserted into the inner wall of the slot.
[0016] The effect achieved by the above components is as follows: by setting up a quick-release mechanism, when it is necessary to replace the filter screen, the rotating rod can be rotated to a certain angle on the filter screen, so that one end slides out of the slot, releasing the restriction on the filter screen. In this way, it can be pulled out from the inner wall of the rectangular slot and the sliding frame for easy replacement. Similarly, it can also be quickly installed for convenient daily maintenance.
[0017] Preferably, magnets are fixedly installed on both sides of one end of the rotating rod, the sliding frame is made of iron, one side of the magnet is magnetically attracted to one side of the inner wall of the slot, and the magnet is inserted into the inner wall of the slot along with the rotating rod.
[0018] The effect achieved by the above components is as follows: by setting a magnet, after one end of the rotating rod is inserted into the inner wall of the slot, the magnet will be attracted to the inner wall of the slot, limiting and fixing the rotating rod, making it more securely engaged.
[0019] Preferably, the quick-release mechanism includes a handle block, wherein both ends of the handle block are fixedly installed on one side of the filter screen.
[0020] The effect achieved by the above-mentioned components is that by setting a handle block, the contact area on one side of the filter screen can be increased, making it easier to pick up and operate when disassembling or installing.
[0021] The beneficial effects of this utility model are:
[0022] By incorporating a cleaning-friendly device, when using a baghouse dust collector to remove dust and gas generated during copper rod production, one end of the hood is connected to the inlet pipe, and the outlet pipe is connected to the subsequent processing equipment. During dust removal, the fan on the baghouse dust collector is activated to guide the dust and gas entering the inlet into the baghouse, where it is filtered through the filter screen inside the sliding frame. The solid particles are intercepted and filtered out, and the filtered gas is discharged through the outlet pipe. Some of the intercepted solid particles adhere to the filter screen, while the rest fall into the dust discharge pipe. Regular cleaning is performed... Solid particles can be discharged by opening the dust discharge pipe. After the filter screen has been used for a period of time, the bag filter can be turned off first, and then the electric telescopic rod can be started to drive the sliding frame to slide in the rectangular hole, so that one end of the used filter screen slides out, while the other end slides into the bag filter for continued filtration. After replacement, the bag filter can be turned on to continue filtration. At this time, the slid-out filter screen can be cleaned, or it can be removed through the quick-release mechanism for easy replacement. This can reduce the number of disassembly and replacement steps, improve the dust removal efficiency of the bag filter, reduce labor costs, and at the same time, it does not require long-term shutdown of the copper rod production line, thus improving production efficiency.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0032] Figure 1-5 The dust control device shown is for copper rod smelting and casting. It includes a bag filter 1, an air inlet pipe 3 on one side of the bag filter 1, an air outlet pipe 4 on the top of the bag filter 1, and a dust discharge pipe 5 at the bottom of the bag filter 1. The bag filter 1 is equipped with a cleaning device 2 inside. When it is necessary to clean or replace the filter screen 24 inside the bag filter 1, the cleaning device 2 can be activated by activating the electric telescopic rod 25 to drive the sliding frame 22 to slide back and forth alternately in the rectangular hole 21. This allows the filter screens 24 inside both ends of the sliding frame 22 to be used alternately. When one filter screen 24 is in use, the other will be exposed on the outer surface of the bag filter 1 for easy cleaning and replacement. The baghouse dust collector 1, with its advantages of high dust removal efficiency and strong adaptability, has become a widely used dust removal device in the copper rod smelting and casting industry. Its working principle is that harmful fumes and gases generated during the copper rod production process enter through the inlet pipe 3 of the dust collector, and are then guided into the interior of the baghouse dust collector 1 by a fan located near the outlet pipe 4. Solid particles in the gas are captured by the internal filter screen 24 and accumulate on the surface. The purified air is discharged through the exhaust pipe, while the filtered solid particles and impurities accumulate on the filter screen 24 or fall into the dust inlet and outlet pipes 5 for discharge, thus achieving gas-solid separation. After the filter screen 24 has been used for a period of time, the easy-cleaning device 2 can be activated to slide out the used filter screen 24, and then the spare filter screen 24 can be moved into the interior of the baghouse dust collector 1 for continued filtration. Then, the surface of the slid-out filter screen 24 is cleaned and replaced. This reduces the disassembly and replacement steps, improves the dust removal efficiency of the baghouse dust collector 1, reduces labor costs, and eliminates the need for long-term shutdown of the copper rod production line, thereby improving production efficiency. It should be noted that the bag filter 1 is a mature technology and equipment in the existing technology, and its internal structure, connection method and principle will not be described here.
[0033] Figure 1-5The cleaning device 2 shown includes a sliding frame 22, a rectangular hole 21 is provided on the inner wall of the bag filter 1, the sliding frame 22 is slidably installed in the inner wall of the rectangular hole 21, and rectangular grooves 23 are provided on the inner walls of both ends of the bag filter 1; two filter screens 24 are inserted into the inner walls of the rectangular grooves 23 and the sliding frame 22, and a quick-release mechanism 29 is provided between one side of the filter screen 24 and the inner wall of the rectangular groove 23; a bracket 26, one side of the bracket 26 is fixedly installed on one side of the bag filter 1; and an electric telescopic rod 25, one end of the electric telescopic rod 25 is fixedly installed on one side of the bracket 26, and the output end is fixedly installed on one side of the sliding frame 22. By incorporating a cleaning-friendly device 2, when using a baghouse dust collector 1 to remove dust and gas generated during the copper rod production process, one end of the hood is connected to the inlet pipe 3, and the outlet pipe 4 is connected to the subsequent processing equipment. During dust removal, the fan on the baghouse dust collector 1 is activated to guide the dust and gas entering the inlet into the baghouse dust collector 1, where it is filtered through the filter screen 24 inside one end of the sliding frame 22, intercepting and filtering out solid particles. The filtered gas is then discharged through the outlet pipe 4. Some of the intercepted solid particles adhere to the filter screen 24, while the rest fall into the dust discharge pipe 5. Regular cleaning can be performed. Solid particles are discharged through the dust exhaust pipe 5. After the filter screen 24 has been used for a period of time, the bag filter 1 can be shut down first. Then, the electric telescopic rod 25 is started to drive the sliding frame 22 to slide in the rectangular hole 21, so that one end of the used filter screen 24 slides out and the other end slides into the bag filter 1 for continued filtration. After replacement, the bag filter 1 is started to continue filtration. At this time, the slid-out filter screen 24 can be cleaned or removed through the quick-release mechanism 29 for easy replacement. This reduces the number of disassembly and replacement steps, improves the dust removal efficiency of the bag filter 1, reduces labor costs, and does not require long-term shutdown of the copper rod production line, thus improving production efficiency.
[0034] Figure 1-5The output rod of the electric telescopic rod 25 shown is symmetrically fixed with reinforcing rods 27, one side of which is fixedly mounted on one side of the sliding frame 22. By setting the reinforcing rods 27, the connection area between the electric telescopic rod 25 and one side of the sliding frame 22 can be increased, making the connection more secure and stable, and less prone to breakage. The longitudinal section of the filter screen 24 is trapezoidal, with the area of the end of the filter screen 24 near the air inlet pipe 3 being larger than that of the other end. By setting the filter screen 24 as a cone, the gas generated during the copper rod production process can pass through the inclined surface of the filter screen 24, and the filtered solid particles will be carried by the gas to the middle position of the bottom of the filter screen 24. This reduces the probability of solid particles clogging the filter holes of the inclined surface of the filter screen 24 and improves the filtration efficiency of the filter screen 24. Sealing blocks 28 are symmetrically fixed on both sides of the sliding frame 22, with one side of the sealing block 28 abutting against the inner wall of the rectangular hole 21. By setting the sealing block 28, the gaps between the two sides of the sliding frame 22 and the rectangular hole 21 can be sealed and blocked, preventing gas from escaping from the gaps and achieving a sealing effect.
[0035] Figure 1-5 The quick-release mechanism 29 shown includes two rotating rods 292, one end of which is rotatably mounted on one side of the filter screen 24. The inner wall of the rectangular groove 23 has symmetrically formed slots 291, and one end of the rotating rod 292 is inserted into the inner wall of the slot 291. By providing the quick-release mechanism 29, when the filter screen 24 needs to be replaced, the rotating rod 292 can be rotated on the filter screen 24 to a certain angle, causing one end to slide out of the slot 291, releasing the restriction on the filter screen 24. This allows it to be pulled out from the inner wall of the rectangular groove 23 and the sliding bracket 22 for easy replacement. Similarly, it can be quickly installed for convenient daily maintenance.
[0036] Figure 1-5 Magnet blocks 293 are fixedly installed on both sides of one end of the rotating rod 292 shown. The sliding frame 22 is made of iron. One side of the magnet block 293 is magnetically attracted to one side of the inner wall of the slot 291. The magnet block 293 is inserted into the inner wall of the slot 291 along with the rotating rod 292. By setting the magnet block 293, after one end of the rotating rod 292 is inserted into the inner wall of the slot 291, the magnet block 293 will be attracted to the inner wall of the slot 291, limiting and fixing the rotating rod 292, making it more securely engaged. The quick-release mechanism 29 includes a handle block 294, with both ends of the handle block 294 fixedly installed on one side of the filter screen 24. By setting the handle block 294, the contact area on one side of the filter screen 24 can be increased, making it easier to pick up and operate during disassembly or installation.
[0037] Working Principle: During the copper rod production process, when using a baghouse dust collector 1 to remove dust and gas generated during production, one end of the hood is connected to the inlet pipe 3, and the outlet pipe 4 is connected to the subsequent processing equipment. During dust removal, the fan on the baghouse dust collector 1 is activated to guide the dust and gas entering the inlet into the baghouse dust collector 1, where it is filtered through the filter screen 24 inside one end of the sliding frame 22. The solid particles are intercepted and filtered out, and the filtered gas is discharged through the outlet pipe 4. Some of the intercepted solid particles adhere to the filter screen 24, while the rest fall into the dust discharge pipe 5. The dust discharge pipe 5 can be opened periodically to discharge the solid particles. After the filter screen 24 has been used for a period of time, the baghouse dust collector 1 can be shut down first, and then restarted. The electric telescopic rod 25 drives the sliding frame 22 to slide in the rectangular hole 21, allowing one end of the used filter screen 24 to slide out while the other end slides into the bag filter 1 for continued filtration. After replacement, the bag filter 1 is started to continue filtration. At this time, the slid-out filter screen 24 can be cleaned. Alternatively, when the filter screen 24 needs to be replaced, the rotating rod 292 can be rotated on the filter screen 24 to a certain angle, causing one end to slide out of the slot 291, releasing the restriction on the filter screen 24. This allows it to be pulled out from the rectangular slot 23 and the inner wall of the sliding frame 22 for easy replacement. This reduces the number of disassembly and replacement steps, improves the dust removal efficiency of the bag filter 1, reduces labor costs, and eliminates the need for long-term shutdown of the copper rod production line, thus improving production efficiency.
