Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal filtration and extraction, in particular to a heavy metal filtration and extraction device for industrial wastewater. Background Art

[0002] Industrial wastewater, including production wastewater, sewage, and cooling water, refers to wastewater and waste liquids generated during industrial production. These wastewaters contain industrial materials, intermediates, by-products, and pollutants that are lost with the water. Industrial wastewater is diverse and complex in composition. For example, electrolytic salt wastewater contains mercury, heavy metal smelting wastewater contains lead, cadmium, and other metals, and electroplating wastewater contains cyanide, chromium, and other heavy metals. Specialized filtration and extraction equipment is required to separate the heavy metals in industrial wastewater.

[0003] Chinese utility model CN216549924U discloses a heavy metal filtration and extraction device for industrial wastewater. A scraping-type heavy metal filtration and extraction structure is designed. The principle is that a scraper is provided in front of the cation exchange resin plate, and a collection mechanism is provided at the bottom of the scraper. By pulling the pull rod upward to drive the scraper to move, the scraper can scrape the heavy metals filtered off the cation exchange resin plate and drop them into the interior for collection.

[0004] However, existing devices are installed inside a wastewater tank. As wastewater flows through the cation exchange resin plates, heavy metals scraped off by the upward-moving scraper are easily affected by the flowing wastewater and washed off the scraper, not necessarily entering the collection shell for collection. Therefore, a filtering and extraction structure that reduces the impact of wastewater flow has been designed to address this issue. Utility Model Content

[0034] Industrial wastewater, including production wastewater, sewage, and cooling water, refers to wastewater and waste liquids generated during industrial production. These wastewaters contain industrial materials, intermediates, by-products, and pollutants that are lost with the water. Industrial wastewater is diverse and complex in composition. For example, electrolytic salt wastewater contains mercury, heavy metal smelting wastewater contains lead, cadmium, and other metals, and electroplating wastewater contains cyanide, chromium, and other heavy metals. Specialized filtration and extraction equipment is required to separate the heavy metals in industrial wastewater.

[0035] In the related art, a scraper is installed in front of the cation exchange resin plate, and a collection mechanism is installed at the bottom of the scraper. By pulling the pull rod upward, the scraper moves, so that the scraper can scrape the heavy metals filtered off the cation exchange resin plate and drop them into the collection shell for collection. However, when the existing device is used, it is installed inside the wastewater tank. When the wastewater flows through the cation exchange resin plate, the heavy metals scraped off by the upward moving scraper are easily affected by the flowing wastewater and washed off the scraper, and may not enter the collection shell for collection.

[0036] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a heavy metal filtration and extraction device for industrial wastewater. When the wastewater is discharged from the pipeline into the wastewater tank 11, it can filter out the heavy metals in the wastewater through the cation exchange resin plate 12. After a period of use, the cation exchange resin plate 12 will adsorb a lot of heavy metals. It is necessary to extract the filtered heavy metals. It is only necessary to pull the handle 14 upward to drive the scraper 13 to move upward. At the same time, the convex plate 24 on one side of the scraper 13 will contact the blade 22 and drive the blade 22 to rotate. Due to the design of the connecting rod 23, the blades rotate at the same time, forming a baffle. At this time, the scraper 13 can scrape the heavy metals on the cation exchange resin plate 12. Because the blade 22 forms a baffle and forms a space between the cation exchange resin plate 12, when the handle 14 is pulled upward, the influence of the wastewater flow can be reduced, so that the scraper 13 will drop the scraped heavy metals into the inside of the collection shell 25 for collection. At this time, pull the handle 26 to pull the collection shell 25 out from the inside of the scraper 13 to clean the heavy metals inside.

[0037] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0038] Combine Figures 1-6 , an embodiment of the present application provides a heavy metal filtration and extraction device for industrial wastewater, comprising: a wastewater tank 11 with a cation exchange resin plate 12 disposed therein; a scraper 13 disposed on one side of the cation exchange resin plate 12; a handle 14 disposed on the top of the scraper 13; a collecting assembly 2 disposed inside the wastewater tank 11, the collecting assembly 2 comprising: a trough body 21 opened inside the wastewater tank 11; a blade 22 disposed inside the wastewater tank 11, and having both ends rotatably connected to the inner side wall of the trough body 21; a connecting rod 23 disposed inside the trough body 21, and having one side rotatably connected to one end of the blade 22; a convex plate 24 disposed on one side of the scraper 13; and a collecting shell 25 disposed on the inner side of the scraper 13.

[0039] Specifically, the arrangement of the blades 22 and the connecting rod 23 is similar to the principle of shutters, so that the blades 22 can rotate at the same time to form a baffle, which can block the flow of part of the wastewater, thereby reducing the impact of the flowing wastewater on scraping. The cation exchange resin plate 12 is mainly used to adsorb anions in water, especially heavy metal ions. These resins can effectively remove calcium ions and magnesium ions in water, thereby softening the water quality. In addition, they can also adsorb other metal ions, such as iron ions, manganese ions, etc., which plays an important role in removing heavy metal ions in wastewater treatment and water purification. In specific applications, such as treating nickel-containing wastewater, the cation exchange resin exchanges the cations on the resin with the anions in the water through the principle of ion exchange, thereby effectively adsorbing nickel ions in the water and achieving wastewater purification.

[0040] During use, wastewater is discharged from the pipeline into the wastewater pool 11 and then filtered through the cation exchange resin plate 12 to filter out heavy metals in the wastewater. After a period of use, a lot of heavy metals will be adsorbed on the cation exchange resin plate 12. It is necessary to extract the filtered heavy metals. You only need to pull the handle 14 upward to drive the scraper 13 to move upward. At the same time, the convex plate 24 on one side of the scraper 13 will contact the blade 22 and drive the blade 22 to rotate. Since the design of the connecting rod 23 is connected to the rotation of one side of the other blades 22, a linkage effect is formed, so it will simultaneously drive the other blades 22 to rotate at the same time to form a baffle. At this time, the scraper 13 can scrape off the heavy metals on the cation exchange resin plate 12. Because the blade 22 forms a baffle and a space is formed between the cation exchange resin plate 12, when the handle 14 is pulled upward, the impact of the wastewater flow can be reduced, so that the scraper 13 is in contact with the cation exchange resin plate 12 on one side, and one side of the scraper 13 is inclined. When the scraper 13 moves upward, the heavy metals can fall into the interior of the collection shell 25 for collection. At this time, the collection shell 25 is pulled out from the inside of the scraper 13 to clean the heavy metals inside.

[0041] In some embodiments, one end of the protruding plate 24 is designed to be arc-shaped.

[0042] During use, the arc-shaped design of the convex plate 24 can make the surface smoother when in contact with the blade 22, thereby reducing scratches on the blade 22.

[0043] In some embodiments, two connecting rods 23 are symmetrically provided.

[0044] When in use, the blades 22 can be better stabilized so that the blades 22 can rotate more simultaneously.

[0045] In some embodiments, the collection assembly 2 further includes a handle 26 disposed inside the collection shell 25 .

[0046] It is convenient to grip during use, so that the collecting shell 25 and the scraper 13 can be separated by pulling the handle 26 .

[0047] In some embodiments, the collecting assembly 2 further includes: a lever 27 disposed inside the trough body 21 , and one end of which is rotatably connected to the inner wall of the trough body 21 ; a reed 28 disposed at the connection between the lever 27 and the trough body 21 .

[0048] Specifically, the function of the reed 28 depends on the elastic deformation of the reed 28. When the blade 22 rotates counterclockwise, a force is applied to the reed 28, causing the reed 28 to undergo elastic deformation. When the blade 22 rotates clockwise and the external force disappears, the reed 28 returns to its original shape.

[0049] During use, after the scraper 13 moves to the bottom of the wastewater pool 11, the convex plate 24 releases the restriction on the blade 22, and the reed 28 rebounds to push the blade 22 to rotate clockwise, so that the wastewater can pass through the blade 22 without manual operation, which is more convenient to use.

[0050] In some embodiments, a snap assembly 3 is provided at the bottom of the collecting shell 25, and the snap assembly 3 includes: a slot 31 opened on the inner wall of the scraper 13; a shell 32 is provided at the bottom of the collecting shell 25; a cross plate 33 is symmetrically provided inside the shell 32; a block 34 is provided on one side of the cross plate 33 and protrudes from the inside of the shell 32; a spring 35 is provided inside the shell 32, and both ends are connected to the cross plate 33.

[0051] When the collection shell 25 needs to be installed inside the scraper 13 during use, the bottom of the collection shell 25 can be directly inserted into the scraper 13, and the shell 32 is inserted into the slot 31, so that the blocks 34 on both sides of the shell 32 are squeezed and retracted into the shell 32. At the same time, the two cross plates 33 move and compress the spring 35 until the shell 32 is fully inserted into the slot 31. The spring 35 rebounds and pushes the cross plates 33 to move so that the blocks 34 engage with the slot 31, which can stabilize the connection between the collection shell 25 and the scraper 13 and make it difficult to separate. When the collection shell 25 needs to be disassembled, it can be directly pulled to squeeze the blocks 34 and retract them from the slot 31.

[0052] In some embodiments, the snap assembly 3 is symmetrically provided in two groups for connecting the collecting shell 25 and the scraper 13 .

[0053] The provision of two sets of snap assemblies 3 can strengthen the connection between the collecting shell 25 and the scraper 13 during use.

[0054] In some embodiments, the buckle assembly 3 further includes: a cross bar 36 disposed on the inner side of the spring 35 , with both ends passing through the cross plate 33 and connected to the inner wall of the shell 32 .

[0055] During use, the arrangement of the cross bar 36 can ensure that the spring 35 will not be compressed when the spring 35 is compressed, thereby better protecting the spring 35.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0057] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0058] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
