Description

Technical Field

[0001] This invention relates to the field of pickling technology, and more specifically, to a pickling tank cover and a pickling apparatus. Background Technology

[0002] The pickling tank cover is a core component of the pickling equipment. During maintenance, when the pickling tank cover needs to be opened, a large amount of acid will remain on the inner wall and surface of the cover due to long-term contact with the acid. This residual acid cannot flow back into the pickling tank through an effective path and can only drip randomly under gravity. The randomly dripping acid will not only corrode the surrounding equipment but also contaminate the workshop floor, creating a safety hazard and reducing the safety of the pickling tank cover during maintenance. Summary of the Invention

[0003] The problem addressed by this invention is how to improve the safety of pickling tank covers during maintenance.

[0004] To address the above problems, the present invention provides a pickling tank cover and a pickling device.

[0005] In a first aspect, the present invention provides a pickling tank cover, a top cover having an outer end face and an inner end face disposed opposite to each other along its own thickness direction, the outer end face being used to connect to an external component to drive the top cover to rotate via the external component, the rotation axis of the top cover being parallel to its own length direction; a pressure cover, the pressure cover being fixedly connected to the inner end face to allow the pressure cover to rotate synchronously with the top cover, the pressure cover being used to contact acid; the pressure cover having a flow guiding channel extending through the pressure cover along the width direction of the top cover, the flow guiding channel being disposed near the end of the pressure cover away from the top cover, the flow guiding channel being used to allow the acid to flow; wherein, the pressure cover has a closed position and an open position, when the pressure cover is in the closed position, the bottom surface of the pressure cover is in contact with the acid; when the pressure cover rotates from the closed position to the open position, residual acid on the pressure cover can flow out through the flow guiding channel.

[0006] The beneficial effects of the pickling tank cover of this invention are: By setting the above structure, the outer end face provides a connection point for the external component, ensuring that the force of the external component can be effectively transmitted to the top cover, realizing the controllable rotation of the top cover; the inner end face is fixedly connected to the pressure cover, ensuring the reliability of the connection between the top cover and the pressure cover, so as to avoid the two from separating during the rotation.

[0007] Secondly, the design of synchronous rotation of the pressure cap and the top cap ensures that their opening and closing actions are consistent, avoiding sealing failure or operational jamming caused by misalignment of their movements.

[0008] Furthermore, the guide channel serves as the flow path for residual acid, guiding the residual acid on the cap to flow out in a fixed direction. The guide channel's through-type design and its location near the other end of the cap allow the acid to naturally collect in the guide channel under gravity during rotation, and the outflow direction can be precisely aligned with the pickling tank, thus facilitating the return of residual acid to the tank for reuse.

[0009] In summary, by directionally guiding the acid flow through the diversion channel, the irregular dripping of acid from existing equipment can be prevented. This avoids the problems of dripping acid corroding surrounding equipment and polluting the workshop floor from the source, thereby reducing equipment maintenance costs and environmental management pressure. Furthermore, the orderly diversion of acid prevents it from dripping onto operators or forming corrosive liquid on the floor, effectively avoiding the safety risks of slipping and skin corrosion, and providing a safe environment for workers. Simultaneously, residual acid returned to the pickling tank can continue to participate in pickling operations, reducing acid waste, lowering raw material consumption costs in the pickling process, and improving production economics.

[0010] Optionally, the pressure cap includes: a connector extending along the length of the top cover, one end of the connector being fixedly connected to the inner end face; a base plate connected to the other end of the connecting plate, and the flow channel being located at the connection between the base plate and the connector.

[0011] Optionally, the pickling tank cover includes a plurality of flow channels, which are spaced apart on the pressure cap along the length of the top cover.

[0012] Optionally, the top cover and the pressure cover are integrally formed.

[0013] Optionally, the bottom plate protrudes from the connector in the width direction of the top cover, and a guide plate is provided between the connector and the portion of the bottom plate protruding from the connector. The guide plate is located at the flow channel and extends from the outer wall of the connector to the edge of the bottom plate on the same side as the outer wall.

[0014] Optionally, a reinforcing plate is provided between the top cover and the bottom plate, and the two ends of the reinforcing plate are respectively connected to the inner end face and the plate surface of the bottom plate facing the inner end face.

[0015] Optionally, the projection of the base plate in the thickness direction of the top cover lies within the projection of the top cover in its own thickness direction.

[0016] Optionally, the connector and the base plate are made of polypropylene.

[0017] Secondly, the present invention provides a pickling apparatus, comprising a plurality of the above-mentioned pickling tank covers, wherein the plurality of pickling tank covers are arranged at intervals along their own length direction.

[0018] The pickling apparatus of this embodiment has the same beneficial effects over the prior art as the pickling tank cover described above, and will not be repeated here.

[0019] Optionally, it further includes: a pickling tank body having a plurality of pickling tanks spaced apart along the length direction of the pickling tank cover, wherein the pickling tanks are configured in one-to-one correspondence with the pickling tank cover, and the pickling tank cover is used to open or close the corresponding pickling tank; and a driving member, which is drivenly connected to the pickling tank cover to drive the pickling tank cover to move between the closed position and the open position.

[0026] like Figures 1-4 As shown, in a first aspect, the present invention provides a pickling tank cover, including a top cover 10 having an outer end face and an inner end face arranged opposite to each other along its own thickness direction. The outer end face is used to connect with an external component to drive the top cover 10 to rotate through the external component. The rotation axis of the top cover 10 is parallel to its own length direction. A pressure cover 20 is fixedly connected to the inner end face so that the pressure cover 20 rotates synchronously with the top cover 10. The pressure cover 20 is used to contact the acid solution. The pressure cover 20 is provided with a flow channel 30, which extends through the pressure cover 20 along the width direction of the top cover 10. The flow channel 30 is located near the end of the pressure cover 20 away from the top cover 10 and is used to supply acid solution flow. The pressure cover 20 has a closed position and an open position. When the pressure cover 20 is in the closed position, the bottom surface of the pressure cover 20 is in contact with the acid solution. When the pressure cover 20 rotates from the closed position to the open position, the acid solution remaining on the pressure cover 20 can flow out through the flow channel 30.

[0027] In this embodiment, by setting the above structure, the outer end face provides a connection point for the external component, ensuring that the force of the external component can be effectively transmitted to the top cover 10, so as to realize the controllable rotation of the top cover 10; the inner end face is fixedly connected to the pressure cover 20, ensuring the reliability of the connection between the top cover 10 and the pressure cover 20, so as to avoid the two from separating during the rotation process.

[0028] Secondly, the synchronous rotation design of the pressure cap 20 and the top cap 10 ensures that their opening and closing actions are consistent, avoiding sealing failure or operational jamming caused by misalignment of their movements.

[0029] Furthermore, the guide channel 30 serves as the flow path for residual acid, guiding the residual acid on the cap 20 to flow out in a fixed direction. The guide channel 30 is a through-type design and is located near the other end of the cap 20, allowing the acid to naturally collect in the guide channel 30 under gravity during rotation. The outflow direction can be precisely aligned with the pickling tank 61, thus facilitating the return of residual acid to the tank for reuse.

[0030] In summary, the directional guidance of the flow channel 30 prevents the irregular dripping of acid from existing equipment, thus avoiding the problems of acid dripping corroding surrounding equipment and polluting the workshop floor. This reduces equipment maintenance costs and environmental protection pressure. Furthermore, the orderly flow of acid prevents it from dripping onto operators or forming corrosive pools on the floor, effectively mitigating the safety risks of slipping and skin corrosion, providing a safe environment for workers. Simultaneously, residual acid returned to the pickling tank 61 can continue to participate in pickling operations, reducing acid waste, lowering raw material consumption costs in the pickling process, and improving production economics.

[0031] In this embodiment, the top of the top cover 10 is provided with a connecting joint, which forms the outer end face.

[0032] In this embodiment, the bottom surface of the top cover 10 forms an inner end face.

[0033] like Figure 1 and Figure 2 As shown, optionally, the pressure cap 20 includes: a connector 21 extending along the length of the top cover 10, one end of the connector 21 being fixedly connected to the inner end face; a base plate 22 connected to the other end of the connecting plate, and a flow channel 30 located at the connection between the base plate 22 and the connector 21.

[0034] By setting the above structure, the connector 21 extends along the length of the top cover 10 and is fixedly connected to the inner end face of the top cover 10. This allows the driving force of the top cover 10 to be evenly transmitted to the pressure cover 20 along the length direction, avoiding loosening or breakage of the connection caused by local stress concentration. This ensures that the pressure cover 20 and the top cover 10 always rotate synchronously and will not be misaligned, thus ensuring the stability of both during rotation.

[0035] Secondly, the acid remaining on the base plate 22 will naturally flow to the connection point with the connector 21 under the action of gravity. This location is the collection point of the acid on the cap 20. Setting the guide channel 30 here will allow the acid to flow into the channel quickly, thereby improving the guide efficiency.

[0036] like Figure 1 and Figure 2 As shown, optionally, the pickling tank cover includes multiple flow channels 30, which are arranged at intervals on the pressure cover 20 along the length of the top cover 10.

[0037] By setting the above structure, since the cap 20 typically has a certain extension dimension along the length of the top cover 10 (adapting to the elongated structure of the pickling tank 61), a single flow channel 30 can only cover a local area, which can easily lead to residual acid in the cap 20 located far from the flow channel 30 in the length direction not being discharged in time. In this embodiment, multiple spaced flow channels 30 can achieve comprehensive flow guidance in the length direction. Each flow channel 30 is responsible for receiving the residual acid in the corresponding area, so that the acid is evenly distributed and synchronously returned on the surface of the cap 20, avoiding local acid accumulation.

[0038] Secondly, the multiple channels set at intervals are equivalent to increasing the number of flow outlets, which significantly increases the acid discharge per unit time. This avoids the problem of acid overflowing from a single channel due to insufficient flow and dripping to the outside, ensuring that the acid flows back to the pickling tank 61 quickly and orderly during the opening process.

[0039] Optionally, the top cover 10 and the pressure cover 20 are integrally formed.

[0040] like Figure 1 and Figure 2 As shown, optionally, the bottom plate 22 protrudes from the connector 21 in the width direction of the top cover 10, and a guide plate 40 is provided between the connector 21 and the part of the bottom plate 22 that protrudes from the connector 21. The guide plate 40 is located at the guide channel 30 and extends from the outer wall of the connector 21 to the edge of the bottom plate 22 on the same side as the outer wall.

[0041] By setting the above structure, the residual acid on the surface of the protruding part of the base plate 22 can easily diffuse to the edge. The guide plate 40 extends from the outer wall of the connector 21 to the same side edge of the base plate 22, which is equivalent to building a guide channel in the protruding area of ​​the base plate 22. This forces the acid that was originally dispersed on the surface of the base plate 22 to be confined within the range of the guide plate 40, preventing the acid from spreading to both sides or dripping along the side of the base plate 22, and ensuring that all residual acid can be accurately guided to the guide channel 30.

[0042] Secondly, the guide plate 40 forms a smooth transition surface with the base plate 22 and the connector 21. When the acid flows along the surface of the guide plate 40 under the action of gravity, the flow resistance is greatly reduced, and it can quickly flow into the guide channel 30 and return to the pickling tank 61, thus avoiding the acid from lingering and accumulating on the surface of the base plate 22.

[0043] like Figure 1 and Figure 2As shown, optionally, a reinforcing plate 50 is provided between the top cover 10 and the bottom plate 22, and the two ends of the reinforcing plate 50 are respectively connected to the inner end face and the plate surface of the bottom plate 22 facing the inner end face.

[0044] By setting the above structure, the base plate 22 is in direct contact with the acid liquid. The acid liquid turbulence pressure and gravity load it bears must be transmitted to the top cover 10 through the inner end face. The reinforcing plate 50 can disperse the local stress of the inner end face here, avoiding loosening and cracking of the connection due to long-term load concentration.

[0045] Meanwhile, the reinforcing plate 50 is directly connected to the inner end face of the base plate 22, thereby providing rigid support for the base plate 22, effectively resisting the mechanical stress caused by acid impact and rotation, ensuring that the base plate 22 can remain flat after long-term use, and avoiding the displacement of the guide channel 30 due to deformation of the base plate 22.

[0046] like Figure 1 and Figure 2 As shown, optionally, the projection of the base plate 22 in the thickness direction of the top cover 10 lies within the projection of the top cover 10 in its own thickness direction.

[0047] By setting up the above structure, the top cover 10 is equivalent to an upper protective cover, which can directly block the acid mist from spreading to the outside of the top cover 10, avoid acid corrosion of surrounding drive components 70 and other precision equipment, and also prevent acid from polluting the workshop floor, thus avoiding the safety risks of operators slipping on the ground due to corrosion and being splashed by acid from the source.

[0048] Meanwhile, the bottom plate 22 is fully covered by the top cover 10, reducing the direct contact area between the bottom plate 22 and the air. The acid mist formed by acid evaporation is confined within the internal space enclosed by the top cover 10 and the bottom plate 22, making it difficult for it to escape outward from the edge of the bottom plate 22. Combined with the sealing structure of the top cover 10 (a water seal in this embodiment), the sealing effect of the acid mist is further improved, reducing the irritation of the acid mist to the respiratory tract and skin of operators, thereby optimizing the workshop working environment.

[0049] Optionally, the connector 21 and the base plate 22 are made of polypropylene.

[0050] By setting the above structure, polypropylene has excellent corrosion resistance to strong acids such as hydrochloric acid, sulfuric acid, and nitric acid commonly used in pickling processes. It will not oxidize, dissolve, or crack, and can resist direct immersion in acid liquid and acid mist corrosion for a long time. Therefore, it can guarantee the service life of connector 21 and base plate 22.

[0051] like Figure 3 As shown, in a second aspect, the present invention provides a pickling apparatus, comprising a plurality of the above-described pickling tank covers, the plurality of pickling tank covers being arranged at intervals along their own length direction.

[0052] The pickling apparatus of this embodiment has the same beneficial effects over the prior art as the pickling tank cover described above, and will not be repeated here.

[0053] Optionally, it also includes: a pickling tank body 60 having a plurality of pickling tanks 61 spaced apart along the length of the pickling tank cover, wherein the pickling tanks 61 are configured one-to-one with the pickling tank cover, and the pickling tank cover is used to open or close the corresponding pickling tank 61; and a driving member 70, which is drivenly connected to the pickling tank cover to drive the pickling tank cover to move between the closed position and the open position.

[0054] By setting the above structure, the pickling tanks 61 of the pickling tank body 60 correspond one-to-one with the tank cover, and the tank cover can be opened and closed independently. When a certain pickling tank 61 needs to be opened, the corresponding tank cover only needs to be opened by the drive component 70, while the other tank covers remain closed and continue to work. This can greatly improve the continuity of production.

[0055] In this embodiment, the pickling tank body 60 also includes a plurality of water seal members 62 spaced apart along the length direction. The top of the water seal member 62 is provided with a water seal groove 63. When the pickling tank cover is in the closed position, the pickling tank cover contacts the water seal grooves 63 of the two water seal members 62 on both sides along the length direction, so as to seal the acid mist through the liquid in the water seal groove 63.

[0056] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
