Covered sealing structure for neutralization tank

Abstract

This utility model relates to the field of covering technology for neutralization tanks, and discloses a sealing structure for covering neutralization tanks, including a tank body. The bottom of the tank body is respectively provided with a left cover plate and a right cover plate. By using the magnetic attraction of the S and N poles of the left and right neodymium magnets, the left and right fluororubber are tightly attached and deformed, thereby filling the installation tolerance and wear gaps after long-term use at the joint. At the same time, the polyurea elastomer coating sprayed on the surface of the fluororubber not only enhances the acid mist corrosion resistance, but also effectively improves the wear resistance of the sealing surface, forming the first high-efficiency sealing barrier. Meanwhile, four sets of airbags are dynamically inflated and deflated using corrugated telescopic tubes to keep them in a full state, thereby filling the edge gaps between the top of the tank body and the bottom of the left and right cover plates. Combined with the wrap-around setting of the C-shaped sealing cover, a second sealing defense line is formed. Thus, under the synergistic effect of the double sealing, the leakage of hydrochloric acid mist is effectively blocked.

Description

Technical Field

[0001] This utility model relates to the field of covering technology for neutralization tanks, specifically to a sealing structure for covering neutralization tanks. Background Technology

[0002] In the treatment of acidic wastewater in industries such as chemical, metallurgical, and electroplating, the neutralization tank, as the core structure for regulating wastewater, needs to be covered and sealed to prevent the leakage of acidic mists such as hydrochloric acid mist, so as to avoid harm to the surrounding environment, equipment, and operators.

[0003] The existing sealing structure of neutralization tanks usually uses a fixed rubber strip for sealing. However, the rubber strip is exposed to an acidic environment for a long time, and is easily corroded by acid mist, aging and hardening, losing its elasticity. It cannot fill the installation tolerance at the joint and the wear gap after long-term use, which may lead to seal failure, gas leakage, and harm to the surrounding environment and the safety of workers.

[0010] As a preferred technical solution of this utility model: the cover sealing assembly is considered as a set of movable components, and there are four sets of such movable components, which are respectively arranged on both sides of the outer wall of the left cover and the coupling.

The four airbags are made of neoprene rubber and lined with nylon mesh.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This sealing structure for the neutralization tank utilizes the magnetic attraction of the S and N poles of the left and right neodymium magnets to tightly bond the left and right fluororubber sheets together and cause deformation. This fills the installation tolerances and wear gaps after long-term use at the bonding point. At the same time, the polyurea elastomer coating sprayed on the fluororubber surface not only enhances the acid mist corrosion resistance but also effectively improves the wear resistance of the sealing surface, forming the first high-efficiency sealing barrier. Meanwhile, four sets of airbags are dynamically inflated and deflated using corrugated telescopic tubes to keep them in a fully inflated state, thereby filling the edge gaps between the top of the tank and the bottom of the left and right cover plates. Combined with the wrap-around setting of the C-shaped sealing cover, a second sealing line is formed. This dual sealing effect effectively prevents the leakage of hydrochloric acid mist.

[0013] 2. This sealing structure for the neutralization tank is driven by a motor coupling to rotate the shaft. Through the threaded engagement of the forward and reverse threaded rods, the left slider slides along the left guide groove and the right slider slides along the right guide groove, allowing for adjustment of the opening and closing range of the left and right covers. This facilitates opening and closing requirements in various scenarios such as maintenance and dredging. Simultaneously, the ceramic scrapers at the bottom of the left and right sliders slide in real-time against the bottom of the guide rail as the sliders move, scraping impurities and crystals into the collection box. This prevents guide rail jamming and transmission obstruction, reducing equipment failures caused by mechanical jamming. Furthermore, the left and right slope panels feature a large slope design with a gentle vertical transition structure, effectively reducing the wind-exposed area. Combined with the high strength of the fiberglass material, it can withstand strong wind impacts, effectively preventing cover deformation or seal failure due to wind pressure.

[0021] 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.

[0022] Please see Figure 1 - Figure 6 The sealing structure for a neutralization tank includes a tank body 1. A left cover plate 2 and a right cover plate 14 are respectively provided at the bottom of the tank body 1. A left slope panel 19 is fixedly installed on the top of the left cover plate 2, and a right slope panel 18 is fixedly installed on the top of the right cover plate 14. A motor 3 is fixedly installed on the outer wall of the tank body 1. A coupling 4 is fixedly sleeved on the outer edge of the output shaft of the motor 3. A rotating shaft 5 is fixedly sleeved on the inner wall of the coupling 4. A belt 17 is provided on the outer wall of the rotating shaft 5. One end of a positive threaded rod 7 is fixedly sleeved on the outer wall of the rotating shaft 5, and the other end of the positive threaded rod 7 is fixedly sleeved. A coupling 2 8 is connected, and a reverse threaded rod 9 is fixedly sleeved on the inner wall of the coupling 2 8. A left slider 10 is fixedly installed at the bottom of the left cover plate 2. A collection box 11 is fixedly installed on the outer wall of the left slider 10. A ceramic scraper 12 is provided on the inner wall of the collection box 11. A guide rail 6 is fixedly installed on the inner wall of the pool body 1. A left guide groove 13 and a right guide groove 21 are respectively opened on the top of the guide rail 6. A splice seam sealing assembly 15 is provided on the inner wall of the left cover plate 2. A cover sealing assembly 16 is provided on the outer wall of the pool body 1. A right slider 20 is fixedly installed at the bottom of the right cover plate 14.

[0023] In the above structure, by setting the right slope panel 18 and the left slope panel 19, the right slope panel 18 and the left slope panel 19 serve as the top structure of the left cover plate 2 and the right cover plate 14. Their manufacturing materials are consistent with those of the sealing cover plate, which are made of glass fiber and additives that are resistant to acids and alkalis, heat, cold and anti-aging. This ensures that the corrosion resistance, strength and stability of the overall structure of the left cover plate 2, the right cover plate 14, the right slope panel 18 and the left slope panel 19 are matched, so as to adapt to the acidic environment in the pool 1. At the same time, the slope of the right slope panel 18 and the left slope panel 19 is set with a large slope and a gentle vertical transition structure, thereby reducing the wind exposure area and making it able to withstand the impact of strong winds.

[0024] This material selection ensures that the corrosion resistance, strength, and stability of the slope panel and cover plate are matched, adapting to the acidic environment of the neutralization tank and meeting the corrosion resistance and durability requirements of the sealed cover structure.

[0025] In a preferred embodiment: the joint sealing assembly 15 includes a left fluororubber 151 embedded in the inner wall of the left cover plate 2, a left neodymium magnet 152 embedded in the inner wall of the left fluororubber 151, a right fluororubber 153 embedded in the inner wall of the right cover plate 14, and a right neodymium magnet 154 embedded in the inner wall of the right fluororubber 153.

[0026] In a preferred embodiment: the unmounted sides of the left rubidium magnet 152 and the right rubidium magnet 154 are the S pole and N pole, respectively, and are magnetically attracted to each other; the unmounted sides of the left fluororubber 151 and the right fluororubber 153 are respectively coated with polyurea elastomer.

[0027] In the above structure, when the left cover plate 2 and the right cover plate 14 slide against each other, the left fluororubber 151 and the right fluororubber 153 embedded in the inner walls of the left cover plate 2 and the right cover plate 14 are bonded together. At this time, when the left fluororubber 151 is bonded to the right fluororubber 153, the S and N poles of the unbonded side of the left neodymium magnet 152 and the right neodymium magnet 154 will generate an attractive magnetic field. Under the magnetic bonding effect of the left neodymium magnet 152 and the right neodymium magnet 154, the bonding area of ​​the left fluororubber 151 and the right fluororubber 153 will deform due to compression. This deformation fills the tolerance of the bonding area between the left cover plate 2 and the right cover plate 14, thus achieving a seal. Secondly, a polyurea elastomer coating is applied to the bonding area between the left fluororubber 151 and the right fluororubber 153 to enhance the acid mist corrosion resistance and wear resistance of the sealing surface, thereby effectively achieving a reliable seal between the splice seam of the left cover plate 2 and the right cover plate 14.

[0028] In a preferred embodiment: the rotating shaft 5, guide rail 6, forward threaded rod 7, coupling 2 8, reverse threaded rod 9, left slider 10, collection box 11, ceramic scraper 12, left guide groove 13, right slider 20, and right guide groove 21 are considered as a set of movable components. There are two sets of these movable components, arranged parallel to each other at the bottom of the left cover plate 2 and the right cover plate 14, respectively. The belt 17 is an annular synchronous belt, and both rotating shafts 5 have synchronous pulleys fitted onto their outer walls to match the belt 17. The two left... The inner wall of the side slider 10 is provided with threads, and the threads are interlocked with the outer wall of the forward threaded rod 7. The outer walls of the two left sliders 10 are respectively attached to the guide rail 6 and the inner wall of the left slider 10 and are slidably disposed. The outer edges of the two ceramic scrapers 12 are attached to the bottom of the guide rail 6 and are slidably disposed. The inner walls of the two right sliders 20 are provided with threads, and the threads are interlocked with the outer wall of the reverse threaded rod 9 and are slidably disposed. The outer walls of the two right sliders 20 are respectively attached to the inner wall of the guide rail 6 and the right guide groove 21 and are slidably disposed.

[0029] In the above structure, the outer edge of the output shaft of the starting motor 3 drives the rotating shaft 5 of one set of movable components to rotate via the coupling 4. The rotating shaft 5 drives the rotating shaft 5 of another set of movable components to rotate synchronously via the meshing of the annular synchronous belt 17 and the synchronous pulley. When the rotating shaft 5 rotates, the forward threaded rod 7 and the reverse threaded rod 9 mesh respectively to drive the left slider 10 to slide along the left guide groove 13 and the right slider 20 to slide in opposite directions along the right guide groove 21, thereby realizing the synchronous opening and closing of the left cover plate 2 and the right cover plate 14. At the same time, during the movement of the left slider 10 and the right slider 20, the outer edge of the ceramic scraper 12 fixed at the bottom slides against the bottom of the guide rail 6 to scrape impurities into the collection box 11, thereby ensuring the cleanliness of the guide rail 6. Therefore, the required opening and closing size of the pool body 1 can be achieved by adjusting the sliding distance of the left cover plate 2 and the right cover plate 14.

[0030] In a preferred embodiment: the cover sealing assembly 16 includes a C-shaped sealing cover 161 fixedly installed on the outer wall of the pool body 1. The inner cavity of the C-shaped sealing cover 161 is provided with an airbag 162. A C-shaped push plate 163 is installed on the outer wall of the left cover 2. A corrugated telescopic tube 164 is provided at the bottom of the C-shaped sealing cover 161. A throttle valve 165 is provided on one side of the corrugated telescopic tube 164, and a one-way air outlet 167 is provided on the other side of the corrugated telescopic tube 164. A C-shaped fixing plate 166 is fixedly installed on the outer wall. The one-way air outlet 167 includes an air outlet pipe 1671 disposed on the outer wall of the airbag 162. An air pressure valve 1672 and a solenoid valve 1673 are respectively disposed on the outer wall of the air outlet pipe 1671. An air inlet pipe 1674 is disposed on the outer wall of the corrugated telescopic pipe 164. An annular gasket 1675 is fixedly installed on the inner wall of the air inlet pipe 1674. A spring 1676 and a sealing ball 1677 are respectively disposed in the inner cavity of the air inlet pipe 1674.

[0031] In a preferred embodiment: the cover sealing assembly 16 is considered as a set of movable components, and there are four sets of such movable components, which are respectively arranged on both sides of the outer wall of the left cover 2 and the coupling 4. The outer walls of the four C-shaped fixing plates 166 have the same shape as the outer walls of the C-shaped push plates 163, and are respectively arranged on both sides of the outer walls of the four airbags 162. The openings on one side of the four C-shaped sealing covers 161 correspond to the fitting points between the top of the pool body 1 and the bottom of the left cover 2 and the right cover 14. The outer walls of the four air outlet pipes 1671 pass through the inner walls of the four C-shaped sealing covers 161 and are connected to the air outlets of the four airbags 162. One end of the four corrugated telescopic pipes 164 is connected and fixed to the outer walls of the four C-shaped push plates 163, and the other end is connected to the four The outer wall of the C-shaped fixing plate 166 is connected and fixed. The four throttle valves 165 are connected to the air inlet ends of the four corrugated telescopic tubes 164. The outer wall of one end of the four air inlet pipes 1674 passes through the bottom of the four C-shaped sealing covers 161 and is connected to the air inlet end of the four airbags 162. The other end is connected and fixed to the air outlet end of the four corrugated telescopic tubes 164. The diameter of the four sealing spheres 1677 is larger than the diameter of the air inlet of the air outlet pipe 1671. The four springs 1676 are located in the middle of the annular gasket 1675 and the sealing spheres 1677. One end is overlapped with the outer wall of the annular gasket 1675 and the other end is overlapped with the outer wall of the sealing spheres 1677. The four airbags 162 are made of neoprene rubber and lined with nylon mesh.

[0032] In the above structure, by aligning one side opening of the four C-shaped sealing covers 161 with the bottom seams of the left and right cover plates 14 of the top of the pool body 1, when the left cover plate 2 and the right cover plate 14 slide in opposite directions to open the left cover plate 2, the opposite sliding of the left cover plate 2 and the right cover plate 14 will simultaneously drive the C-shaped push plates 163 fixed on both sides to slide along the outer wall of the C-shaped sealing cover 161. This causes the C-shaped push plates 163 to simultaneously compress one end of the corrugated telescopic tube 164 as it slides, thus causing the corrugated telescopic tube 164 to slide synchronously. 4. Compression begins. At this time, the gas inside the corrugated telescopic tube 164 pushes the sealing ball 1677 under compression, causing the sealing ball 1677 to compress the spring 1676 and disengage from the air inlet of the air inlet pipe 1674. The air inlet of the air inlet pipe 1674 then opens, allowing the gas inside the air inlet pipe 1674 to enter the inner cavity of the airbag 162. This replenishes the airbag 162 with gas, ensuring that the airbag 162, made of neoprene rubber and nylon mesh, remains fully inflated, thus filling the pool 1. The sealing seam between the top and the bottom of the left cover plate 2 and the right cover plate 14, and the air pressure valve 1672 located on the outer wall of the air outlet pipe 1671, will monitor the air pressure value inside the airbag 162 in real time. This allows the air inside the airbag 162 to be discharged when the air pressure value inside the airbag 162 is too high by activating the solenoid valve 1673. Secondly, when the left cover plate 2 and the right cover plate 14 return to their original position, the C-shaped push plate 163 will compress and reset one end of the corrugated telescopic tube 164 under the synchronous drive of the C-shaped push plate 163. At this time, the inside of the corrugated telescopic tube 164... When the air pressure in the chamber is negative, the throttle valve 165 opens, allowing air from outside the pool 1 to enter the inner cavity of the corrugated telescopic tube 164 through the throttle valve 165 to achieve gas balance. Secondly, when there is no gas pushing, the sealing ball 1677 is reset and fixed to the air inlet of the air outlet pipe 1671, which is smaller than the diameter of the sealing ball 1677, by the spring 1676, thereby achieving a seal and preventing the backflow of gas in the inner cavity of the airbag 162. This keeps the airbag 162 in a state of full gas deformation, thus better isolating the leaked gas at the sealing seam.

[0033] Working principle: Firstly, when the device is in the closed state, its left cover plate 2 and right cover plate 14 are tightly fitted together. The joint sealing assembly 15 and the cover plate sealing assembly 16 together achieve an overall seal of the pool body 1. Under the magnetic attraction of the S pole of the left neodymium magnet 152 and the N pole of the right neodymium magnet 154, the left and right fluororubber 151 and fluororubber 153 are tightly fitted together. Due to compression, the left and right fluororubber 151 and fluororubber 153 deform, filling the tolerance at the joint. Simultaneously, the surfaces of the left and right fluororubber 151 and fluororubber 153 are coated with a polyurethane coating. Urea elastomer enhances acid mist corrosion resistance and wear resistance, and blocks leakage at the splice seams. Secondly, the airbag 162 of the cover sealing assembly 16, made of neoprene rubber and lined with nylon mesh, is in an inflated state. The inflated airbag 162 fills the joint between the top of the pool body 1 and the bottom of the left cover 2 and the right cover 14 through the opening on one side of the C-shaped sealing cover 161. At the same time, the left slope panel 19 and the right slope panel 18 are made of glass fiber and corrosion-resistant additives. The left slope panel 19 and the right slope panel 18 are designed with a large slope and a smooth vertical transition structure, which effectively reduces the wind-receiving area and has the effect of withstanding strong wind impact.

[0034] Secondly, the output shaft of motor 3 can be started and driven by coupling 4 to rotate the shaft 5 of one set of moving components. The rotating shaft 5 is driven by the engagement of the annular synchronous belt 17 and the synchronous pulley, which drives the shaft 5 of another set of moving components to rotate synchronously. When the shaft 5 rotates, the forward threaded rod 7 and the reverse threaded rod 9 drive the left slider 10 to slide in the opposite direction along the left guide groove 13 and the right slider 20 along the right guide groove 21 through thread engagement, and simultaneously drive the left cover plate 2 and the right cover plate 14 to separate synchronously. The left neodymium magnet 152 and the right neodymium magnet 154 lose their magnetic force due to the separation of the left cover plate 2 and the right cover plate 14, and the left fluororubber 151 and the right fluororubber 153 are released from the attached state. At the same time, when the left cover plate 2 and the right cover plate 14 slide, they will also drive the C-shaped push plate 163 to slide along the outer wall of the C-shaped sealing cover 161. This causes the C-shaped push plate 163 to slide synchronously, compressing one end of the corrugated telescopic tube 164. This causes the corrugated telescopic tube 164 to begin compressing. At this time, the gas inside the corrugated telescopic tube 164 pushes the sealing ball 1677 under compression, causing the sealing ball 1677 to compress the spring 1676 and disengage from the air inlet of the air inlet pipe 1674. At this time, the air inlet of the air inlet pipe 1674 opens, allowing the gas inside the air inlet pipe 1674 to enter the inner cavity of the airbag 162, thereby ensuring that the airbag 162 is always full to fill the dynamic gap. At the same time, the air pressure valve 1672 monitors the air pressure inside the airbag 162 in real time. If it is too high, the solenoid valve 1673 is activated to release and reduce pressure. Meanwhile, during the movement of the left slider 10 and the right slider 20, the ceramic scraper 12 at the bottom slides against the bottom of the guide rail 6, scraping impurities into the collection box 11, thereby ensuring the smooth operation of the guide rail 6.

[0035] When the left cover plate 2 and the right cover plate 14 are closed at the joint, the left neodymium magnet 152 and the right neodymium magnet 154 are re-attracted, and the left fluororubber 151 and the right fluororubber 153 are squeezed and deformed to restore the joint seal. At the same time, the C-shaped push plate 163 moves back with the left cover plate 2 and the right cover plate 14, causing the corrugated telescopic tube 164 to return to its original position and extend. At this time, a negative pressure is formed in the inner cavity of the corrugated telescopic tube 164, causing the throttle valve 165 to open. The air outside the pool 1 enters the corrugated telescopic tube 164 through the throttle valve 165 to achieve pressure balance. At the same time, the sealing ball 1677 is reset and blocks the air inlet pipe 1674 under the action of the spring 1676 to prevent the gas in the inner cavity of the airbag 162 from flowing back and to maintain the edge seal.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
