Description

Technical Field

[0001] This utility model relates to the field of rock wool production technology, and in particular to a tail gas filtration chamber for a rock wool production line. Background Technology

[0002] During the production of rock wool, the exhaust gas discharged from both the cotton collecting machine and the curing furnace contains impurities such as rock wool fibers, resin, broken cotton or slag balls. In order to meet environmental requirements, it needs to be filtered through a filter chamber before being discharged.

[0003] In existing rock wool production line tail gas filter chambers, when filtering the tail gas generated during rock wool production, excessive impurities accumulate on the surface of the filter plates due to prolonged use. To ensure cleaning efficiency, cleaning components are usually installed for cleaning, which is relatively convenient and does not require disassembling the filter plates. However, with long-term use, a large amount of impurities accumulate at the bottom of the filter chamber, requiring the machine to be stopped for cleaning, which prevents the filter chamber from working properly when cleaning impurities. Utility Model Content

[0004] In view of this, the present invention provides a tail gas filtration chamber for a rock wool production line. The main technical problem to be solved is that the filtration chamber cannot perform filtration work while cleaning impurities.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tail gas filtration chamber for a rock wool production line, comprising a filtration chamber, wherein a filter plate and a purification filter membrane are fixedly connected sequentially from left to right inside the filtration chamber; a cleaning device is movably connected inside the filtration chamber; an exhaust device is fixedly connected to the right side inside the filtration chamber; an adsorbent box is fixedly connected to the right side of the top of the filtration chamber; a waste box is fixedly connected to the lower part of the filtration chamber; a sealing cover is fixedly connected to the bottom of the waste box; the waste box includes a box body fixedly connected to the bottom of the filtration chamber, and both sides of the box body are... The box is provided with a slot. A connecting block is fixedly connected to the inner side of the box body. A hydraulic telescopic rod is movably connected between the connecting blocks. A fixed block is movably connected to the end of the hydraulic telescopic rod away from the connecting block. A support column is movably connected to the top of the fixed block. A rotating plate is fixedly connected to the top of the support column. A first sealing strip is fixedly connected to the side of the rotating plate away from the inner wall of the box body. A second sealing strip is fixedly connected to the side of the rotating plate near the inner wall of the box body. A rotating column is fixedly connected to the side of the rotating column near the inner wall of the box body. A rotating cylinder is movably connected to the outer side of the rotating column. The rotating cylinder is fixedly connected to the box body.

[0006] By adopting the above technical solution, the extension of the hydraulic telescopic rod is controlled to push the rotating plate to rotate, thereby allowing the rotating plates to close together. This also causes the first sealing strip between the two rotating plates to close together, and the second sealing strip to adhere to the inner wall of the filter chamber. This isolates the filter chamber from the waste box, ensuring that exhaust gas does not escape through the waste box when cleaning impurities. This allows for simultaneous cleaning and filtration. After closing, the sealing cover can be opened directly to remove impurities. Once cleaning is complete, the sealing cover can be fixed in place. Then, controlling the hydraulic telescopic rod to retract will rotate the rotating plate back to its original position, allowing impurities to fall into the box. After a certain amount of impurities accumulate in the box, the rotating plate can be closed again and the sealing cover opened to remove the impurities.

[0007] As a further description of the above technical solution: the filter chamber includes a chamber body, an air inlet duct is fixedly connected to the left side of the chamber body, an air outlet duct is fixedly connected to the right side inside the chamber body, a waste trough is provided at the bottom of the chamber body, and a rod groove is provided at the top of the chamber body.

[0008] By adopting the above technical solution, the air inlet duct is used for the entry of exhaust gas, the air outlet duct is used for the discharge of exhaust gas after cleaning, the waste trough is used for the passage of impurities, and the rod groove is used for the movement of the pull rod.

[0009] As a further description of the above technical solution: the adsorbent tank includes a box body fixedly connected to the top right side of the chamber body, a water inlet pipe fixedly connected to the top of the box body, a through pipe fixedly connected to the left side of the box body, a valve installed on the outside of the through pipe, and a spray box fixedly connected to the lower end of the through pipe.

[0010] By adopting the above technical solution, the adsorbent box is filled with a reagent for adsorbing harmful gases. By opening the valve, the reagent can enter the pipe and be sprayed onto the surface of the purification filter membrane through the spray box, thus improving its treatment effect on harmful gases.

[0011] As a further description of the above technical solution: the exhaust device includes a fixed column fixedly connected to the inside of the air outlet, a motor fixedly connected to the inside of the fixed column, and a fan blade fixedly connected to the output end of the motor.

[0012] By adopting the above technical solution, starting the motor enables the fan blades to rotate, allowing the air inside the filter chamber to be discharged through the air outlet, thereby creating negative pressure inside the chamber, allowing the exhaust gas to continuously enter the chamber through the air inlet.

[0013] As a further description of the above technical solution: the cleaning device includes a sliding column fixedly connected to the inside of the chamber, a movable column movably connected to the outside of the sliding column, a brush fixedly connected to the right side of the movable column, and a pull rod fixedly connected to the top of the movable column, the pull rod being movably connected to the chamber.

[0014] By adopting the above technical solution, the moving column can be raised and lowered by pulling the lever up and down, thereby enabling the brush to clean the filter plate, ensuring that the impurities on the filter plate can be removed and preventing blockage. The cleaned impurities will enter the waste box through the waste trough under the action of gravity.

[0015] As a further description of the above technical solution: the sealing cover includes locking blocks that snap onto both sides of the compartment body, a cover body is fixedly connected between the locking blocks, and a sealing gasket is fixedly connected to the top of the cover body.

[0016] By adopting the above technical solution, the material of the card block is relatively soft, and it can be deformed by compression, making it easy to be locked in the card slots on both sides of the box. Furthermore, the sealing gasket makes the seal between the card block and the waste box better.

[0017] By employing the above technical solution, the tail gas filtration chamber of the rock wool production line of this utility model has the following beneficial effects:

[0018] Compared to existing technologies, the tail gas filtration chamber of this rock wool production line, by incorporating a waste box, facilitates simultaneous filtration and impurity removal within the filtration chamber. By controlling the extension of a hydraulic telescopic rod, the rotating plates are able to rotate, causing them to close together. This closes the first sealing strip between the two plates, and the second sealing strip adheres to the inner wall of the filter chamber, effectively isolating the filter chamber from the waste box. This prevents tail gas from escaping through the waste box while impurities are being removed, allowing for simultaneous filtration and impurity removal. After closure, the sealing cover can be opened directly to remove impurities. Once cleaning is complete, the sealing cover can be fixed in place. Retracting the hydraulic telescopic rod again rotates the rotating plates back to their original position, allowing impurities to fall into the box. Once a certain amount of impurities has accumulated in the box, the rotating plates can be closed again and the sealing cover opened for further removal. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Reference Figure 1-6The present invention provides a tail gas filtration chamber for a rock wool production line, comprising a filter chamber 1. Inside the filter chamber 1, a filter plate 2 and a purification filter membrane 5 are fixedly connected from left to right. The filter plate 2 is used to filter impurities such as rock wool fibers, resin, broken cotton and slag balls in the tail gas, and the purification filter membrane 5 is used to treat harmful gases in the tail gas, ensuring that the discharged tail gas is cleaner. A cleaning device 6 is movably connected inside the filter chamber 1. An exhaust device 4 is fixedly connected to the right side inside the filter chamber 1. An adsorbent box 3 is fixedly connected to the right side of the top of the filter chamber 1. A waste box 7 is fixedly connected to the lower part of the filter chamber 1. A sealing cover 8 is fixedly connected to the bottom of the waste box 7. The waste box 7 includes a box body 701 fixedly connected to the bottom of the filter chamber 1. Both sides of the box body 701 are provided with slots 702 for the insertion of locking blocks 803. A connecting block 703 is fixedly connected to the inner side of the box body 701. A hydraulic telescopic rod 704 is movably connected between the connecting blocks 703. A fixing block 706 is movably connected to the end of the hydraulic telescopic rod 704 away from the connecting block 703. 4. It can rotate between the inner side of the fixed block 706 and the connecting block 703 to ensure that it can smoothly push the rotating plate 707 to rotate. The top of the fixed block 706 is movably connected to the support column 705, which is used to support the rotating plate 707 to ensure its strength. The top of the support column 705 is fixedly connected to the rotating plate 707. The side of the rotating plate 707 away from the inner wall of the box 701 is fixedly connected to the first sealing strip 708, which is used to ensure the sealing between the rotating plates 707. The side of the rotating plate 707 close to the inner wall of the box 701 is fixedly connected to the second sealing strip 709, which is used to ensure the sealing between the rotating plate 707 and the filter chamber 1. A rotating column 710 is fixedly connected to the side of the rotating plate 707 near the inner wall of the box 701. A rotating cylinder 711 is movably connected to the outer side of the rotating column 710. The rotating cylinder 711 is fixedly connected to the box 701. The rotating cylinder 711 and the rotating column 710 can rotate relative to each other, so that the rotating plate 707 can rotate inside the filter chamber 1.

[0029] By controlling the extension of the hydraulic telescopic rod 704, the rotating plate 707 can be pushed to rotate, thereby allowing the rotating plate 707 to close together. This also causes the first sealing strip 708 between the two rotating plates 707 to close together, and the second sealing strip 709 to adhere to the inner wall of the filter chamber 1. This isolates the filter chamber 1 from the waste box 7, ensuring that exhaust gas will not be discharged through the waste box 7 when cleaning impurities in the waste box 7. This allows the filter to perform filtering work while cleaning impurities. After closing, the sealing cover 8 can be opened directly to clean out the impurities. After cleaning, the sealing cover 8 can be fixed in place. Then, by controlling the retraction of the hydraulic telescopic rod 704, the rotating plate 707 can be rotated back to its original position, allowing the impurities to fall into the box 701. After the impurities in the box 701 accumulate to a certain level, the rotating plate 707 can be closed again and the sealing cover 8 can be opened to clean out the impurities.

[0030] Furthermore, the filter chamber 1 includes a chamber body 101. An air inlet duct 105 is fixedly connected to the left side of the chamber body 101 for the entry of exhaust gas. An air outlet duct 103 is fixedly connected to the right side inside the chamber body 101 for the discharge of exhaust gas after cleaning. A waste trough 104 is provided at the lower part of the chamber body 101 for the passage of impurities. A rod groove 102 is provided at the top of the chamber body 101 for the movement of the pull rod 602.

[0031] Furthermore, the adsorbent box 3 includes a box 301 fixedly connected to the top right side of the chamber 101. The box 301 contains an adsorbent for harmful gases. A water inlet pipe 302 is fixedly connected to the top of the box 301 for loading the adsorbent. A through pipe 304 is fixedly connected to the left side of the box 301. A valve 303 is installed on the outside of the through pipe 304. A spray box 305 is fixedly connected to the lower end of the through pipe 304. By opening the valve 303, the adsorbent can enter the through pipe 304 and be sprayed onto the surface of the purification filter membrane 5 through the spray box 305, thereby improving its treatment effect on harmful gases.

[0032] Furthermore, the exhaust device 4 includes a fixed column 401 fixedly connected to the inside of the air outlet duct 103. A motor 402 is fixedly connected to the inside of the fixed column 401. A fan blade 403 is fixedly connected to the output end of the motor 402. Starting the motor 402 causes the fan blade 403 to rotate, allowing the air inside the filter chamber 1 to be discharged through the air outlet duct 103, thereby creating a negative pressure inside the chamber 101, allowing the exhaust gas to continuously enter the chamber 101 through the air inlet duct 105.

[0033] Furthermore, the cleaning device 6 includes a sliding column 601 fixedly connected to the inner side of the chamber 101. The sliding column 601 is used to restrict the movement of the moving column 604 to ensure its movement is more stable. The moving column 604 is movably connected to the outer side of the sliding column 601. A brush 603 is fixedly connected to the right side of the moving column 604. The brush 603 is in contact with the filter plate 2. A pull rod 602 is fixedly connected to the top of the moving column 604. The pull rod 602 is movably connected to the chamber 101. By pulling the pull rod 602 up and down, the moving column 604 can be raised and lowered, thereby enabling the brush 603 to clean the filter plate 2, ensuring that the impurities on the filter plate 2 can be cleaned and preventing blockage. The cleaned impurities will enter the waste box 7 through the waste trough 104 under the action of gravity.

[0034] Furthermore, the sealing cover 8 includes locking blocks 803 that snap onto both sides of the bin body 101. The locking blocks 803 are made of a relatively soft material and can be deformed by compression, making it easy to snap onto the slots 702 on both sides of the bin body 701. The cover body 801 is fixedly connected between the locking blocks 803, and a sealing gasket 802 is fixedly connected to the top of the cover body 801. The sealing gasket 802 is used to ensure the airtightness between it and the waste bin 7.

[0035] Working principle:

[0036] During operation, starting the motor 402 causes the fan blades 403 to rotate, allowing air inside the filter chamber 1 to be discharged through the exhaust duct 103. This creates negative pressure inside the chamber 101, allowing exhaust gas to continuously enter the chamber 101 through the intake duct 105. When excessive impurities accumulate inside the filter chamber, the hydraulic telescopic rod 704 extends to push the rotating plate 707 to rotate. This causes the rotating plates 707 to close together, and the first sealing strip 708 between the two rotating plates 707 closes together, causing the second sealing strip 709 to adhere to the inner wall of the filter chamber 1. This isolates the filter chamber 1 from the waste box 7, ensuring that exhaust gas does not escape through the waste box 7 when cleaning impurities in it. This allows for simultaneous cleaning and filtration of impurities. After sealing, the sealing cover 8 can be opened directly to clean out the impurities. After cleaning, the sealing cover 8 can be fixed in place. Then, the hydraulic telescopic rod 704 can be retracted to drive the rotating plate 707 to rotate back to its original position, so that the impurities can fall into the box 701. After the impurities in the box 701 accumulate to a certain extent, the rotating plate 707 can be closed again and the sealing cover 8 can be opened to clean out the impurities.
