Description

Technical Field

[0001] This utility model relates to the field of electrode sealing technology, and in particular to a corrosion-resistant electrode water seal structure. Background Technology

[0002] Electrode water seal structures are often used in industries such as smelting, electroplating, batteries, water treatment, and electrolytic hydrogen production. Through the water seal function, it can prevent harmful gases generated during the production process from leaking from the gap between the electrode and the equipment, while blocking external dust, impurities, and moisture from entering the electrode working area, thus avoiding contamination of the electrolyte and affecting the electrode reaction efficiency. Patent CN222783003U discloses a corrosion-resistant electrode water seal structure, belonging to the field of electrode sealing. It includes a water seal box with an open upper side. A corresponding water seal cover and electrode device are sequentially arranged above the water seal box. The water seal cover is sealed to the electrode device via graphite packing. The electrode device passes through the water seal cover and the water seal box. Corrosion-resistant rubber sleeves are provided on the inner wall of the water seal box and the side wall of the water seal cover. A water exchange device is provided on the side of the water seal box. This corrosion-resistant electrode water seal structure, through the corrosion-resistant rubber sleeves on the inner wall of the water seal box and the side wall of the water seal cover, resists the corrosion of phosphoric acid. The water exchange device below the water seal box replaces the phosphoric acid in the isolated water with clean water, and the phosphoric acid adsorbed on the corrosion-resistant rubber sleeves is also flushed out, thereby reducing the phosphoric acid content in the water seal box. While the aforementioned corrosion-resistant electrode water seal structure addresses phosphoric acid corrosion through corrosion-resistant rubber sleeves on the inner wall of the water seal tank and the side wall of the water seal cover, and the water exchange device below the water seal tank replaces the phosphoric acid in the isolated water with clean water, thus flushing out the phosphoric acid adsorbed on the corrosion-resistant rubber sleeves and reducing the phosphoric acid content in the water seal tank, it only removes a portion of the free phosphoric acid by replacing it with clean water. It cannot separate solid impurities in the water, and these impurities will continue to accumulate at the bottom of the water seal tank. Long-term accumulation will wear down the corrosion-resistant rubber sleeves and clog the sealing gaps. Furthermore, it relies on passive, one-time water replacement, requiring frequent shutdowns for maintenance, resulting in low practicality. Therefore, a corrosion-resistant electrode water seal structure needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a corrosion-resistant electrode water seal structure to solve the problems of low water change efficiency and incomplete cleaning of the inner wall of the water seal tank in existing corrosion-resistant electrode water seal structures.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a corrosion-resistant electrode water seal structure, including a water seal box; The top of the water seal tank is equipped with a water seal cover, and an electrode is inserted into the water seal cover. The water seal tank is equipped with a self-circulating cleaning mechanism. The self-circulating cleaning mechanism includes an inlet pipe and an outlet pipe connected inside the water seal tank, and a micro water pump is installed on the inlet pipe. An inverted conical cyclone separator is connected between the inlet pipe and the outlet pipe. The bottom of the inverted conical hydrocyclone is fixed with a threaded cover plate, and the bottom of the threaded cover plate is threadedly connected to a filter cylinder. The bottom of the filter cylinder is evenly threadedly connected to a sedimentation box, and the bottom of the sedimentation box is fitted with a metal salt precipitant reaction layer. The bottom of the water seal box is equipped with a water exchange pipe that is connected to the outlet pipe, and the top of the water exchange pipe is movably connected to a rotating nozzle via a rotary joint.

[0005] Furthermore, flanges are provided on the inlet pipe, outlet pipe, and inverted conical hydrocyclone, and an activated carbon filter layer is provided inside the outlet pipe.

[0006] Furthermore, the metal salt precipitant reaction layer is a porous plastic shell filled with metal salt precipitant.

[0007] Furthermore, the outer wall of the rotating nozzle is uniformly provided with nozzles, and there are several nozzles.

[0008] Furthermore, the inner wall of the water seal box is sequentially fitted with a first corrosion-resistant liner and a second corrosion-resistant liner, and both the first corrosion-resistant liner and the second corrosion-resistant liner are made of fluororubber.

[0009] Furthermore, the inner wall of the water seal box is provided with a sealing airbag pressure block that matches the first corrosion-resistant liner and the second corrosion-resistant liner, and an air valve is installed on the sealing airbag pressure block.

[0010] Furthermore, the water seal cover is fitted with a clamp that matches the electrode by screws, and the water seal cover is connected to the electrode and the clamp by a graphite packing seal.

[0011] The present invention provides a corrosion-resistant electrode water seal structure, the advantages of which are: Equipped with a self-circulating cleaning mechanism, a micro water pump, along with inlet and outlet pipes, enables self-circulating cleaning, eliminating the need for manual water changes or cleaning. This solves the problem of frequent shutdowns for maintenance required by traditional water seal structures. Furthermore, by setting up an inverted conical hydrocyclone, the advantage of using centrifugal force to separate solid impurities is realized. This causes wastewater containing impurities to move at high speed along the inner wall in a spiral motion. The denser solid impurities are thrown towards the inner wall and slide down through the sedimentation box inside the filter cartridge, where they react with the metal salt precipitant reaction layer to form insoluble phosphate precipitates. This achieves the separation and removal of phosphate ions in the wastewater. Moreover, the return water is transported to the rotating nozzle through the water exchange pipe, and the nozzles on the outer wall of the rotating nozzle spray water to thoroughly rinse the inner wall of the water seal tank without dead angles, preventing impurities from adhering and optimizing the cleaning effect of the water seal tank. By incorporating a second corrosion-resistant liner and using a first and second corrosion-resistant liner made of fluororubber that are fastened to the inner wall of the water seal tank, the erosion of the water seal tank body by the medium can be prevented. Furthermore, when replacing the liner, it is only necessary to release the air from the sealing airbag pressure block through the air valve, then fasten and replace it with a new liner structure. After that, the sealing airbag pressure block on the inner wall of the water seal tank is inflated to tightly compress the first and second corrosion-resistant liners, ensuring that there are no gaps between the liner and the tank wall, thus guaranteeing the sealing performance of the liner structure after fastening.

[0014] 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.

[0015] Please see Figures 1-5 The present invention provides a corrosion-resistant electrode water seal structure, including a water seal box 1.

[0016] Reference Figures 1-4 A water seal cover 5 is installed on the top of the water seal tank 1, and an electrode 3 is inserted into the water seal cover 5. A self-circulating cleaning mechanism 2 is installed on the water seal tank 1. The self-circulating cleaning mechanism 2 includes an inlet pipe 204 and an outlet pipe 206 connected inside the water seal tank 1. A micro water pump 205 is installed on the inlet pipe 204, and an inverted conical cyclone separator 201 is connected between the inlet pipe 204 and the outlet pipe 206. The bottom of the inverted conical hydrocyclone 201 is fixed with a threaded cover plate 202, and the bottom of the threaded cover plate 202 is threadedly connected to a filter cylinder 203. The bottom of the filter cylinder 203 is evenly threadedly connected to a sedimentation box 209, and the bottom of the sedimentation box 209 is fitted with a metal salt precipitant reaction layer 208. The bottom of the water seal box 1 is provided with a water exchange pipe 7 that is connected to the outlet pipe fitting 206, and the top of the water exchange pipe 7 is movably connected to a rotating nozzle 9 through a rotary joint 8. Flanges 207 are provided on the inlet pipe 204, outlet pipe 206 and inverted conical hydrocyclone 201. An activated carbon filter layer is provided inside the outlet pipe 206. The metal salt precipitant reaction layer 208 is a porous plastic shell filled with metal salt precipitant. The outer wall of the rotating nozzle 9 is evenly provided with nozzles, and there are 4 nozzles.

[0017] An external power supply is connected, and the micro water pump 205 starts to achieve the function of circulation power and fluid transportation. Specifically, the phosphorus-containing and impurity-containing wastewater in the water seal tank 1 is pumped to the inverted conical hydrocyclone 201 through the inlet pipe 204, forming a continuous self-circulating flow path. After the wastewater containing impurities enters the inverted conical hydrocyclone 201, it undergoes high-speed spiral motion along the inner wall of the hydrocyclone. The denser solid impurities are thrown towards the inner wall of the inverted conical hydrocyclone 201 under the action of centrifugal force, and slide down the wall to the bottom filter cartridge 203. The phosphate ions in the wastewater enter the sedimentation box 209 in the filter cartridge 203, come into contact with the metal salt precipitant reaction layer 208 and react, producing... Phosphate precipitates that are insoluble in water, thus fixing and removing phosphate ions. This achieves good hydrocyclone separation and impurity precipitation. After separation by the inverted conical hydrocyclone 201 and phosphorus removal by the sedimentation box 209, the wastewater is returned to the water seal tank 1 through the outlet pipe 206. The activated carbon filter layer inside the outlet pipe 206 further adsorbs the tiny suspended solids and pigments in the wastewater, improving the quality of the returned water. Finally, the returned water is transported to the rotary nozzle 9 through the water exchange pipe 7. The four nozzles on the outer wall of the rotary nozzle 9 spray water to thoroughly rinse the inner wall of the water seal tank 1, preventing impurities from adhering. This self-circulating cleaning saves water and reduces maintenance costs.

[0018] Reference Figure 3 and Figure 5 The inner sidewall of the water seal box 1 is sequentially fitted with a first corrosion-resistant inner liner 6 and a second corrosion-resistant inner liner 11, and the material of the first corrosion-resistant inner liner 6 and the second corrosion-resistant inner liner 11 is fluororubber. The inner wall of the water seal box 1 is provided with a sealing airbag block 10 that matches the first corrosion-resistant liner 6 and the second corrosion-resistant liner 11, and an air valve 12 is installed on the sealing airbag block 10.

[0019] In use, the first corrosion-resistant liner 6 and the second corrosion-resistant liner 11, made of fluororubber, are fitted onto the inner wall of the water seal tank 1. These liner components are in direct contact with corrosive media. Utilizing the excellent resistance of fluororubber to phosphoric acid corrosion, they prevent the media from eroding the water seal tank 1 body. When it is necessary to replace the first corrosion-resistant liner 6 and the second corrosion-resistant liner 11, simply release the air from the sealing airbag pressure block 10 through the air valve 12, then install the new liner structure. After that, inflate the sealing airbag pressure block 10 on the inner wall of the water seal tank 1 to tightly compress the first corrosion-resistant liner 6 and the second corrosion-resistant liner 11, ensuring that there are no gaps between the liner and the tank wall, thus guaranteeing the strong sealing performance of the liner structure after installation.

[0020] Reference Figure 1 The water seal cover 5 is fitted with a clamp 4 that matches the electrode 3 by screws. The water seal cover 5 is connected to the electrode 3 and the clamp 4 by a graphite packing seal.

[0021] In use, the water seal box 1 and the water seal cover 5 form a closed water seal space. By injecting clean water into the water seal box 1, a liquid seal layer is formed, which prevents the escape of corrosive gas generated when the electrode 3 is working. In addition, the water seal cover 5 fixes the electrode 3 with the clamp 4, and the graphite packing is used to achieve a sealed connection between the electrode 3 and the water seal cover 5 and the clamp 4, so as to prevent corrosive media from leaking from the gap between the electrode 3 and the cover, thereby achieving the basic water seal function. The clamp 4 is divided into two symmetrical parts and is fixed with screws, which facilitates the clamping and fixing of the electrode 3.
