Description

Technical Field

[0001] This utility model relates to the field of zinc liquid circulation filtration technology, and in particular to a zinc liquid circulation filtration device for galvanized sheet production. Background Technology

[0002] Galvanized steel sheet refers to steel sheet with a layer of zinc coating on its surface. The zinc layer primarily enhances the steel sheet's corrosion resistance and offers advantages in appearance and processing performance. In terms of corrosion protection, zinc is more reactive than iron; when in contact with electrolytes, zinc acts as the anode, preferentially oxidizing and forming a "sacrificial anode" to protect the iron substrate. The zinc layer itself is also a dense metallic film, isolating corrosive media. In ordinary atmospheric environments, galvanized steel sheet has a corrosion resistance lifespan 5-10 times longer than ordinary steel sheet, with even more significant protection in harsh environments. Furthermore, galvanized steel sheet has a smooth, metallic luster, and passivation treatment can further enhance corrosion resistance and improve its appearance. The zinc coating has good ductility, making it less prone to cracking during stamping and welding. Due to its strong corrosion resistance, it reduces the need for rust prevention treatment, lowering maintenance costs. Moreover, the galvanizing process is mature, with lower costs than stainless steel, and zinc is recyclable, making it a high-performance, cost-effective material to replace ordinary steel sheet and meet moderate corrosion protection requirements.

[0003] Patent publication number "CN220767130U" discloses a "zinc liquid circulation device," comprising a reaction tank, a filter chamber, and a collection tank. A shielding door is provided above the reaction tank. The collection tank is fixedly connected to the side wall of the filter chamber. An injection port and a delivery pipe are respectively connected through the side wall of the reaction tank. A drain pipe is connected through the bottom of the reaction tank. Both the drain pipe and the delivery pipe are equipped with solenoid valves. The drain pipe is connected to the filter chamber through the solenoid valves. Through the coordinated use of the transmission module, circulation pump, heat dissipation module, and filter screen, heavy metal waste gas that may be generated during zinc electrolysis can be absorbed, reducing heavy metal pollution. While filtering the zinc liquid, the filtered residue can also be automatically cleaned, reducing the working cycle. Rapid cooling of the zinc liquid also reduces the filtration load, extends the service life of the filter media, and ensures the stability of the liquid composition.

[0004] In the aforementioned patent, if the reacted plates in the reaction tank are difficult to lift out of the solution during the reaction process, it will not only hinder the normal flow of materials, making it impossible to remove the reacted plates in time, but also prolong the single reaction cycle, reduce production efficiency, and increase equipment operating costs. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a zinc liquid circulation filtration device for galvanized sheet production.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a zinc liquid circulation filtration device for galvanized sheet production, including a collection frame, a reaction mechanism arranged above the collection frame, a rotation mechanism and a circulation mechanism respectively arranged on one side of the collection frame, and a filtration mechanism respectively arranged inside the collection frame;

[0009] The reaction mechanism includes a reaction frame and a servo hydraulic cylinder. One side surface of the servo hydraulic cylinder is fixedly installed on the front and rear surfaces of the reaction frame, respectively. A placement frame is provided inside the reaction frame. The two sides of the placement frame are slidably connected to the inner wall of the front and rear surfaces of the reaction frame, respectively. A solenoid valve penetrating the bottom surface is fixedly installed on the bottom wall of the reaction frame.

[0010] By adopting the above technical solution, the plates to be reacted are placed in an orderly manner in the placement frame. The placement frame is driven to be immersed in the solution by a servo hydraulic cylinder. After the reaction is completed, the servo hydraulic cylinder exerts force again to push the placement frame installed at the output end to lift the plates out of the solution, thereby significantly shortening the production cycle and improving production efficiency. This solves the problems that if the plates that have completed the reaction in the reaction tank are difficult to lift out of the solution, it will not only hinder the normal flow of materials and prevent the plates that have completed the reaction from being taken out in time, but also prolong the single reaction cycle, reduce production efficiency, and increase equipment operating costs.

[0011] In a preferred embodiment of the zinc liquid circulation filtration device for galvanized sheet production described in this utility model, the rotating mechanism includes a servo motor and a drive wheel. One end of the drive wheel is fixedly installed at the output end of the servo motor. An outer cover is provided on the outside of the servo motor, and a driven wheel is provided inside the outer cover. Toothed belts are respectively wound and meshed on the outside of the driven wheel and the drive wheel.

[0012] By adopting the above technical solution, the servo motor can drive the drive wheel to rotate, and the toothed belt wrapped around the outside of the rotating drive wheel can synchronously drive the driven wheel to rotate.

[0014] By adopting the above technical solution, the collection frame can provide a stable fixing effect for the reaction frame installed at the top.

[0015] As a preferred embodiment of the zinc liquid circulation filtration device for galvanized sheet production described in this utility model, the filtration mechanism includes a filter frame and slots. The slots are respectively opened on the top surface of the filter frame and penetrate through the interior. A screw is rotatably connected to the inner wall of one end of the slot, and the other end of the screw is rotatably connected to the inner wall of the other end of the slot and penetrates through the surface of the other end. Scrapers are screwed to the outer side of the screw, and the other ends of the scrapers are slidably connected to the inner walls on both sides of the slot.

[0016] By adopting the above technical solution, the scrapers screwed to the outside of the screw move along the screw axis through the rotation of the screw. The moving scrapers can effectively scrape off the impurities on the filter surface of the filter frame, causing them to detach from the filter surface, thereby avoiding the accumulation of impurities and clogging the filter screen, and ensuring filtration efficiency.

[0017] In a preferred embodiment of the zinc liquid circulation filtration device for galvanized sheet production described in this utility model, the two side surfaces of the filter frame of the filtration mechanism are respectively fixedly installed on the inner wall of the front end and the inner wall of the rear end of the collection frame. The bottom port of the solenoid valve of the reaction mechanism is located above the surface of the filter frame. A receiving frame is provided below one end of the filter frame. One end of the receiving frame passes through the front surface and the front inner wall of the collection frame and is inserted into the rear inner wall. The other end port of the driving wheel and the other end port of the driven wheel of the rotating mechanism are respectively fixedly installed on the other end port of the screw.

[0018] By adopting the above technical solution, the scraped impurities can fall into the receiving frame in an orderly manner under the push of the scraper, thereby achieving the effect of centralized processing.

[0019] As a preferred embodiment of the zinc liquid circulation filtration device for galvanized sheet production described in this utility model, the circulation mechanism includes an output pipe and a circulation pump. The output end of the circulation pump is fixedly installed on one side surface of the output pipe and penetrates the inner wall of one side. An input pipe is fixedly installed at the top end of the output pipe. The bottom end of the output pipe is fixedly installed on one side surface of the collection frame and penetrates the inner wall of one side. The top end of the input pipe is fixedly installed on one side surface of the reaction frame of the reaction mechanism and penetrates the inner wall of one side.

[0020] By adopting the above technical solution, the zinc liquid that has been filtered multiple times is temporarily stored in the collection box, and then pumped into the output pipe by the circulation pump. Then, driven by the circulation pump, the zinc liquid is directionally transported along the output pipe to the input pipe, and finally flows into the reaction box to achieve recycling, effectively improving the resource utilization rate.

[0022] This utility model provides a zinc bath circulation filtration device for galvanized sheet production. It has the following beneficial effects:

[0023] 1. By adding a reaction mechanism, the plates to be reacted are placed in an orderly manner in the placement frame.

This solves the problems that if the plates that have completed the reaction in the reaction tank are difficult to lift out of the solution, it will not only hinder the normal flow of materials and prevent the plates that have completed the reaction from being taken out in time, but also prolong the single reaction cycle, reduce production efficiency, and increase equipment operating costs.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Example 1

[0034] Reference Figures 1 to 5 This is the first embodiment of the present utility model. This embodiment provides a zinc liquid circulation filtration device for galvanized sheet production, including a collection frame 2, a reaction mechanism 1 is arranged above the collection frame 2, a rotation mechanism 3 and a circulation mechanism 5 are respectively arranged on one side of the collection frame 2, and a filtration mechanism 4 is respectively arranged inside the collection frame 2.

[0035] The reaction mechanism 1 includes a reaction frame 11 and a servo hydraulic cylinder 12.

One end of the outer cover 35 is fixedly installed on one side surface of the collection frame 2.

[0037] Furthermore, the reaction mechanism 1 places the plates to be reacted in an orderly manner in the placement frame 13, and drives the placement frame 13 to immerse in the solution with the help of the servo hydraulic cylinder 12. After the reaction is completed, the servo hydraulic cylinder 12 exerts force again to push the placement frame 13 installed at the output end to lift it up, so that the plates are removed from the solution, thereby greatly shortening the production cycle and significantly improving production efficiency. The solution that needs to be filtered is discharged in an orderly manner through the solenoid valve 14, and the bottom surface of the reaction frame 11 is installed on the top of the collection frame 2.

[0038] The servo motor 31 of the rotating mechanism 3 can drive the drive wheel 32 to rotate, so that the toothed belt 33 that is wound and meshed on the outside of the rotating drive wheel 32 can synchronously drive the driven wheel 34 to rotate. Since the servo motor 31 is provided with an outer cover 35, the outer cover 35 can effectively provide protection.

[0039] Example 2

[0040] Reference Figures 1 to 5This is the first embodiment of the present invention. Based on the previous embodiment, the filter mechanism 4 includes a filter frame 41 and a slot 42. The slot 42 is respectively opened on the top surface of the filter frame 41 and penetrates the interior. A screw 43 is rotatably connected to the inner wall of one end of the slot 42. The other end of the screw 43 is rotatably connected to the inner wall of the other end of the slot 42 and penetrates the surface of the other end. Scrapers 44 are screwed to the outside of the screw 43. The other end of the scraper 44 is slidably connected to the inner walls of both sides of the slot 42. The two sides of the filter frame 41 of the filter mechanism 4 are respectively fixedly installed on the inner wall of the front end and the inner wall of the collection frame 2. The bottom port of the solenoid valve 14 of the reaction mechanism 1 is located above the surface of the filter frame 41. A receiving frame 6 is provided below one end of the filter frame 41. One end of the receiving frame 6 penetrates the front surface and the front inner wall of the collection frame 2 and is inserted into the rear inner wall. The other end of the driving wheel 32 and the other end of the driven wheel 34 of the rotating mechanism 3 are respectively fixedly installed on the other end of the screw 43.

[0041] Specifically, the circulation mechanism 5 includes an output pipe 51 and a circulation pump 52. The output end of the circulation pump 52 is fixedly installed on one side surface of the output pipe 51 and penetrates one side inner wall.

The top end of the input pipe 53 is fixedly installed on one side surface of the reaction frame 11 of the reaction mechanism 1 and penetrates one side inner wall.

[0042] Furthermore, the filtration mechanism 4 drives the screw 43, which is installed at the other end, to rotate through the driving wheel 32 and driven wheel 34 of the rotating mechanism 3. The rotating screw 43 drives the scraper 44, which is screwed to the outside, to move along the axis of the screw 43. The moving scraper 44 can effectively scrape off the impurities on the filter surface of the filter frame 41, causing them to detach from the filter surface, thereby avoiding the accumulation of impurities and clogging the filter screen, and ensuring filtration efficiency. The other end of the screw 43 is rotatably connected to the inner wall of the other end of the slot 42 and penetrates the surface of the other end. The scraped impurities can fall into the receiving frame 6 in an orderly manner under the push of the scraper 44, thereby achieving the effect of centralized processing.

[0043] The zinc liquid filtered multiple times by the circulation mechanism 5 is temporarily stored in the collection box 2. It is then pumped into the output pipe 51 by the circulation pump 52. Driven by the circulation pump 52, the zinc liquid is directionally transported along the output pipe 51 to the input pipe 53 and finally flows into the reaction box 11 to achieve recycling and effectively improve resource utilization.

[0044] Working principle: The reaction mechanism 1 places the plates to be reacted in an orderly manner in the placement frame 13. The placement frame 13 is driven to be immersed in the solution by the servo hydraulic cylinder 12. After the reaction is completed, the servo hydraulic cylinder 12 exerts force again to push the placement frame 13 installed at the output end to lift it up, so that the plates are removed from the solution, which greatly shortens the production cycle and significantly improves production efficiency. The solution that needs to be filtered is discharged in an orderly manner through the solenoid valve 14. The bottom of the reaction frame 11 is installed on the top of the collection frame 2.

[0045] The servo motor 31 of the rotating mechanism 3 can drive the drive wheel 32 to rotate, so that the toothed belt 33 that is wound and meshed on the outside of the rotating drive wheel 32 can synchronously drive the driven wheel 34 to rotate. Since the servo motor 31 is provided with an outer cover 35, the outer cover 35 can effectively provide protection.

[0046] The filtration mechanism 4 drives the screw 43, which is installed at the other end, to rotate through the driving wheel 32 and driven wheel 34 of the rotating mechanism 3. The rotating screw 43 drives the scraper 44, which is screwed to the outside, to move along the axis of the screw 43. The moving scraper 44 can effectively scrape off the impurities on the filter surface of the filter frame 41, causing them to detach from the filter surface, thereby avoiding the accumulation of impurities and clogging the filter screen, and ensuring filtration efficiency. The other end of the screw 43 is rotatably connected to the inner wall of the other end of the slot 42 and penetrates the surface of the other end. The scraped impurities can fall into the receiving frame 6 in an orderly manner under the push of the scraper 44, thereby achieving the effect of centralized processing.

[0047] The zinc liquid filtered multiple times by the circulation mechanism 5 is temporarily stored in the collection box 2. It is then pumped into the output pipe 51 by the circulation pump 52. Driven by the circulation pump 52, the zinc liquid is directionally transported along the output pipe 51 to the input pipe 53 and finally flows into the reaction box 11 to achieve recycling and effectively improve resource utilization.
