DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0029] Please refer to Figure 1-6 A non-ferrous metal smelting wastewater treatment equipment includes a concentration box 1 and a solid-liquid separation mechanism. The concentration box 1 is connected to the solid-liquid separation mechanism through a feed pipe 2. The solid-liquid separation mechanism includes an outer cylinder 3 and an inner cylinder 4. The outer cylinder 3 is coaxially arranged with the inner cylinder 4. Both ends of the inner cylinder 4 extend out of the outer cylinder 3 respectively. One end of the feed pipe 2 is connected with the inner cylinder 4. The circumference of the inner cylinder 4 is provided with filter holes 41. A separation chamber 6 is formed between the inner cylinder 4 and the outer cylinder 3. A drain pipe 61 is provided at the bottom of the separation chamber 6. A sealing mechanism is provided at the bottom of the inner cylinder 4.

[0030] A magnetic attraction component 11 is provided in the central box 1. The magnetic attraction component 11 is arranged in a stepped manner in the central box 1. The magnetic attraction component can be an adsorbed object such as a magnet.

[0031] When in use, heavy metal capture agents are added to smelting wastewater to make it strongly chelate with heavy metal ions. The chelated wastewater is injected into the magnetic suction component 11 in the central box 1, and part of the heavy metals are first removed by the magnetic suction component 11; then the smelting wastewater enters the solid-liquid separation mechanism (inner cylinder 4) through the feed pipe 2, at which time the wastewater will pass through the filter hole 41 into the separation chamber 6, and finally be discharged from the drain pipe 61; and the filtered flocculent precipitate or concentrate stays in the inner cylinder 4, and is discharged from the bottom of the inner cylinder 4 after the sealing mechanism is opened.

[0032] In this embodiment, the blocking mechanism includes a blocking ball 7, which is provided with a through hole 71 for discharging concentrate, and the outer wall of the blocking ball 7 is provided with an adjusting rod 72 extending outward, and when the adjusting rod 72 rotates, it drives the blocking ball 7 to rotate in the inner tube 4, and the blocking ball 7 is interference fit with the inner tube 4. The outer circumference of the blocking ball 7 is provided with an elastic rubber layer to prevent wastewater from sticking out and ensure sealing.

[0033] During the solid-liquid separation process, the adjusting rod 72 is rotated to drive the sealing ball 7 to rotate, so that the through hole 71 is in a horizontal state. At this time, the bottom of the inner tube 4 is sealed, the flocculent precipitate or concentrate remains in the inner tube 4, and the wastewater enters the separation chamber 6; when the flocculent precipitate or concentrate needs to be discharged, the adjusting rod 72 is rotated again, and the through hole 71 is in a vertical state. At this time, the internal flocculent precipitate or concentrate will flow out vertically downward from the through hole 71 to complete the discharge.

[0034] In the scheme of the present invention, in order to prevent precipitation or concentrate from adhering to the inner wall sealing filter hole 41 of the inner cylinder, a built-in stirring and scraping device is arranged in the solid-liquid separation mechanism, and the stirring and scraping device includes a core shaft 51 in the inner cylinder 4, and the core shaft 51 is coaxially connected to the motor 5 at the top of the inner cylinder 4, and a plurality of fixed disks 52 are evenly arranged on the circumference of the core shaft 51, and a horizontally extending extension rod 53 is arranged on the fixed disk 52, and a scraper 54 is arranged at the end of the extension rod 53, and the scraper 54 is always in contact with the inner wall of the inner cylinder 4.

[0035] Since the scraper 54 always contacts the inner wall of the inner tube 4, after the motor 5 is running, the scraper 54 will rotate with the core shaft 51. At this time, the end of the scraper 54 will always scrape the inner wall of the inner tube 4 to scrape off the attached flocculent precipitation or concentrate, ensuring that the wastewater is filtered smoothly through the filter holes.

[0036] Furthermore, the extension directions of each two adjacent extension rods 53 are opposite, and the upper and lower parts of the scraping tracks of each two upper and lower adjacent scrapers 54 overlap, ensuring that the inner wall of the inner cylinder 4 can be completely scraped, further improving the filtering efficiency.

[0037] See also Figure 7-10 In the solution of the present invention, the scraper 54 includes a fixed plate 541 and a flexible scraper plate 542. One side of the fixed plate 541 is fixedly connected to the end of the extension rod 53, and the other side is detachably connected to the flexible scraper plate 542. When the flexible scraper plate 542 is severely worn, it can be replaced regularly. The end of the flexible scraper plate 542 is arc-shaped; wherein the flexible scraper plate 542 has an interference fit with the inner cylinder wall to improve the scraping effect.

[0038] Specifically, a groove 5411 extending inward is provided at the end of the fixing plate 541, and a waist groove 5412 is provided on the surface of the fixing plate 541 on one side of the groove 5411, and the waist groove 5412 is communicated with the groove 5411. A plug-in rod 5421 corresponding to the groove 5411 is provided at the bottom of the flexible scraper plate 542, and a flexible limiting block 5423 corresponding to the waist groove 5412 is provided on one side of the plug-in rod 5421. A second spring 5422 is fixed to the bottom end of the plug-in rod 5421. When the plug-in rod 5421 is inserted into the groove 5411, the second spring 5422 contacts the inner bottom surface of the groove 5411, and at the same time, the flexible limiting block 5423 is engaged in the waist groove 5412. When the plug-in rod 5421 is extended and retracted by the second spring 5422, the flexible limiting block 5423 moves in the waist groove 5412.

[0039] When installing the flexible scraper plate 542, firstly, the plug-in rod 5421 is aligned with the sink groove 5411, and then the flexible scraper plate 542 is pressed into the sink groove 5411, at which time the flexible limit block 5423 is deformed and follows the plug-in rod 5421 into the sink groove 5411; Since the flexible limit block 5423 corresponds to the waist groove 5412, the flexible limit block 5423 will return to its original position and enter the waist groove 5412 after the plug-in rod 5421 enters the sink groove 5411; when the second spring 5422 is extended or retracted, the flexible limit block 5423 will move in the waist groove 5412; the establishment of the flexible limit block 5423 can prevent the flexible scraper plate 542 (plug-in rod 5421) from detaching from the sink groove 5411. In addition, the second retractable spring 5422 can push the plug-in rod 5421, so that the flexible scraper plate 542 is in tight contact with the inner wall of the inner tube 4, making the scraping effect more ideal.

[0040] In order to quickly disassemble the flexible scraper plate 542 and the fixing plate 541; the fixing plate 541 is provided with two symmetrical L-shaped fixing plates 5413 on the same side of the waist groove 5412, and a holding plate 5414 is provided between the two L-shaped fixing plates 5413, and the inner side of the holding plate 5414 is provided with a holding protrusion 5416 corresponding to the waist groove 5412.

[0041] A first spring 5415 is provided between the pressing plates 5414 and 541 , and a cross section of the pressing protrusion 5416 coincides with the waist groove 5412 . When the pressing plate 5414 moves toward the fixing plate 541 , the pressing protrusion 5416 moves into the waist groove 5412 .

[0042] In this embodiment, a slide groove is provided on the inner side of the L-shaped fixing plate 5413, and sliders corresponding to the slide groove are provided at both ends of the holding plate 5414, so that the holding plate 5414 can stably move along the slide groove toward the fixing plate 541; Since a pressing protrusion 5416 is provided on the inner side of the pressing plate 5414, and the pressing protrusion 5416 corresponds to the waist groove 5412, when the pressing plate 5414 moves toward the fixed plate 541, the pressing protrusion 5416 will enter the waist groove 5412, and after entering the waist groove 5412, it will push the flexible limiting block 5423; after the flexible limiting block 5423 is pushed, the flexible limiting block 5423 no longer limits the plug-in rod 5421, and the entirety can be pulled out from the sink groove 5411 at this time, and replaced after disassembly.

[0043] In addition, in this embodiment, the first spring 5415 is always in a compressed state to prevent the holding plate 5414 from moving toward the fixing plate 541 .

[0044] Based on the above embodiment, the flexible scraper plate 542 and the flexible limiting block 5423 are both made of elastic rubber material, and may of course be other compressible elastic materials.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
