Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] During the wet steel grit blasting process, a large amount of wastewater containing iron impurities will be generated. These wastewaters need to be purified by solid-liquid separation to remove iron powder and broken steel grit in the wastewater, so that the purified wastewater can be recycled. This application mainly uses a magnetic solid-liquid separation device to absorb and separate iron impurities in wastewater by magnetic adsorption, thereby achieving the purpose of purifying water quality.

[0057] Please refer to Figures 1 to 10The present application provides a magnetic solid-liquid separation device, which includes: a magnetic separation component 1, which includes a magnetic roller 11, a slag removal roller 12 spaced apart from the magnetic roller 11, and a conveyor belt 13 connecting the magnetic roller 11 and the slag removal roller 12; a liquid storage tank 2 with a first inner cavity 21, the liquid storage tank 2 is arranged below the magnetic roller 11, and the liquid storage tank 2 includes a top with a water outlet and a bottom with an emptying port 22; a water inlet guide plate 3, which is spaced apart from the magnetic roller 11, and the water inlet guide plate 3 and the clamping area of ​​the magnetic roller 11 form an adsorption channel 31, and the outlet of the adsorption channel 31 is arranged in the first inner cavity 21; a water distributor 4, which is provided with a water distribution port 41, and the water distribution port 41 can guide water to the adsorption channel 31; a scraper 5, which is arranged close to the slag removal roller 12.

[0058] On the whole, the magnetic solid-liquid separation device provided by the present application evenly distributes the sewage to the magnetic roller 11 through the water distributor 4, and the sewage flows along the adsorption channel 31 between the water inlet guide plate 3 and the magnetic roller 11, and then the iron impurities are adsorbed by the magnetic roller 11, and then the iron impurities reach the slag removal roller 12 along the conveyor belt 13, and the iron impurities on the conveyor belt 13 can be scraped off by the cooperation of the scraper 5 and the slag removal roller 12, thereby realizing the adsorption separation process; and the sewage treated by the magnetic roller 11 will flow into the liquid storage tank 2, and then can be discharged from the water outlet of the liquid storage tank 2, thereby realizing the continuous water outlet process. The present application can evenly distribute the sewage and prolong the contact time between the sewage and the magnetic roller by setting the adsorption channel 31, increase the adsorption rate of iron impurities, and make the effluent water quality better.

[0059] In this application specification, the present invention will be described in detail with reference to specific implementation methods and drawings.

[0060] For details, please refer to Figures 1 to 10 The magnetic solid-liquid separation device may include: a magnetic roller 11; a slag removal roller 12; a conveyor belt 13; a liquid storage tank 2; a water inlet guide plate 3; a water distributor 4; a scraper 5; a shell 7; and a slag storage tank 6.

[0061] In this embodiment, the magnetic solid-liquid separation device may include a shell 7 having a third inner cavity 71, the magnetic separation component 1 is arranged in the third inner cavity 71, the first inner cavity 21 can guide water to the third inner cavity 71 through the water outlet, and the shell 7 is provided with a drain port 72 communicating with the third inner cavity 71, and the height of the drain port 72 does not exceed the height of the water outlet. Specifically, the shell 7 can adopt a rectangular structure. During installation, part of the liquid storage tank 2 can be arranged inside the shell 7, and the bottom of the liquid storage tank 2 with the drain port 22 can be arranged outside the shell 7, so that the liquid storage tank 2 can more easily discharge the water therein. By setting the shell 7, it can play a protective and blocking role, prevent water splashing caused during the operation of the conveyor belt 13 or the water delivery process of the water distributor 4, so that the working environment of the entire device can be cleaner and tidier.

[0062] In this embodiment, the water inlet guide plate 3 includes a first guide plate 32 and a second guide plate 33 connected to the first guide plate 32. The first guide plate 32 is longitudinally extended in the height direction, the first guide plate 32 is arranged on the side of the magnetic roller 11, the second guide plate 33 is arranged in an arc shape, the second guide plate 33 is at least partially arranged below the magnetic roller 11, and the second guide plate 33 is spaced from the magnetic roller 11 to form the adsorption channel 31.

[0063] Specifically, the first guide plate 32 and the second guide plate 33 are connected to the inner wall of the side shell 7. The second guide plate 33 can be arranged concentrically with the magnetic roller 11, that is, the curvature of the second guide plate 33 can match the curvature of the outer surface of the magnetic roller 11, and an adsorption channel 31 with equal gaps is formed between the second guide plate 33 and the magnetic roller 11, which is beneficial to: making the sewage uniformly distributed in the adsorption channel 31, and then making the magnetic roller 11 able to generate a strong adsorption magnetic force on the iron impurities in the adsorption channel 31, so that the magnetic roller 11 can fully adsorb the iron impurities in the sewage, and improve the purification effect of the magnetic roller 11 on the sewage.

[0064] The corresponding relationship between the iron impurity content in sewage, the gap size of the adsorption channel 31 and the magnetic force of the magnetic roller 11 can be stored in advance. During installation or use, the gap of the adsorption channel 31 and the magnetic force of the magnetic roller 11 can be appropriately selected according to the iron impurity content in sewage, and then the gap of the adsorption channel 31 and the magnetic force of the magnetic roller 11 can be pre-adjusted so that the device can obtain the best adsorption purification effect. Specifically, the magnetic roller 11 in the present application can be selected as a permanent magnet roller body or a roller body with an adjustable magnetic force function. The user can reasonably choose according to the actual situation, and there is no restriction here. The water inlet guide plate 3 in the present application can be fixed with the shell 7, or it can be movably installed on the shell 7 through the position adjustment device in the prior art. The user can reasonably determine the installation method of the water inlet guide plate 3 according to the use needs, and there is no restriction here. When the water inlet guide plate 3 is movably installed on the shell 7, a sliding seal can be set between the water inlet guide plate 3 and the inner wall of the shell 7 on both sides.

[0065] In this embodiment, the height of the slag stripping roller 12 does not exceed the height of the magnetic roller 11, and the conveyor belt 13 includes an adsorption section 131 that fits the magnetic roller 11, a scraping section 132 that fits the slag stripping roller 12, and a first conveying section 133 and a second conveying section 134 located between the adsorption section 131 and the scraping section 132. The first conveying section 133 is located above the second conveying section 134, and the first conveying section 133 is used to guide the slag particles from the adsorption section 131 to the scraping section 132. Specifically, the height of the slag stripping roller 12 is lower than the height of the magnetic roller 11, so that the impurities adsorbed by the magnetic roller 11 can slide down along the conveyor belt 13 to the slag stripping roller 12 under the action of gravity, so as to prevent the impurities adsorbed by the magnetic roller 11 from re-entering the sewage, thereby improving the removal rate of iron impurities. Of course, the user can reasonably adjust the positional relationship between the magnetic roller 11 and the slag stripping roller 12 according to needs, and there is no restriction here.

[0066] Furthermore, a tensioning device 8 is provided on the side of the second conveying section 134, and the tensioning device 8 includes a tensioning adjustment frame 82 and a tensioning roller 81 arranged on the tensioning adjustment frame 82, and the tensioning roller 81 overlaps the second conveying section 134. Specifically, the tensioning adjustment frame 82 includes tensioning guide rods 821 symmetrically arranged on both sides of the tensioning roller 81, and each of the tensioning guide rods 821 is sequentially provided with a first nut 822, a tensioning adjustment seat 823, a second spring 824, a support plate 825 and a second nut 826 along the height direction, and the two ends of the tensioning roller 81 can be connected to the tensioning adjustment seat 823 on both sides through the bracket 83. When in use, the position of the tensioning adjustment seat 823 can be adjusted by the first nut 822 and the second nut 826, thereby driving the tensioning roller 81 to tension the conveyor belt 13, so that the conveyor belt 13 runs more stably and reliably, and prevents the conveyor belt 13 from slipping and affecting the slag removal effect. Of course, users can also use other tensioning structures in the prior art as needed, which is not limited here.

[0067] The scraper 5 may leave some small-sized impurities on the conveyor belt 13. In order to prevent the impurities left on the conveyor belt 13 from returning to the water body, in this embodiment, a flushing device 9 is provided on the side of the second conveying section 134. The flushing device 9 includes a flushing adjustment frame 92 and a flushing nozzle 91 arranged on the flushing adjustment frame 92. The flushing nozzle 91 is provided with a plurality of flushing holes 911, and the flushing holes 911 are arranged facing the outer side of the second conveying section 134. Specifically, the flushing adjustment frame 92 includes flushing guide rods 921 symmetrically arranged on both sides of the flushing nozzle 91. Each of the flushing guide rods 921 is sequentially provided with a third nut 922, a flushing adjustment seat 923 and a fourth nut 924 in the height direction. The flushing nozzle 91 can be connected to the flushing adjustment seats 923 on both sides through a pipe clamp 925. Among them, a plurality of flushing holes 911 can be provided on the flushing nozzle 91, and the plurality of flushing holes 911 can be arranged evenly spaced to enhance the flushing effect.

[0068] When in use, the position of the flushing nozzle 91 is controlled by adjusting the third nut 922 and the fourth nut 924, so that the flushing nozzle 91 can fully clean the impurities remaining on the conveyor belt 13, prevent the impurities from returning to the water body, and improve the water quality of the outlet water. Of course, the user can also set other types of cleaning structures as needed, such as flushing with high-pressure gas, or cleaning by oscillation, and then magnetic adsorption by a magnetic device. The user can reasonably select or combine various methods according to needs, and there is no limitation here.

[0069] In this embodiment, the water distributor 4 includes a distribution tank body 42 and a flow equalizing plate 43. The water distribution port 41 is arranged on the side wall of the distribution tank body 42. The flow equalizing plate 43 is movably connected to the distribution tank body 42 along the height direction of the water distribution port 41. The size of the water distribution port 41 can be adjusted by the flow equalizing plate 43. Specifically, three adjustment slots 431 can be provided on the flow equalizing plate 43. The adjustment slots 431 are longitudinally extended along the height direction and arranged on the flow equalizing plate 43. The side wall of the distribution tank body 42 is provided with an adjustment bolt 44 that matches the adjustment slot 431. The adjustment bolt 44 passes through the adjustment slot 431 to movably connect the flow equalizing plate 43 to the distribution tank body 42.

[0070] In actual use, if the water outlet 41 is too large or too small, it will affect the uniformity of water distribution. The opening size of the water outlet 41 can be adjusted by the flow equalizer 43, so that the sewage can flow more evenly along the water outlet 41 to the magnetic roller 11, thereby increasing the adsorption effect of the magnetic roller 11 on iron impurities. The user can reasonably adjust the size of the water outlet 41 according to needs to obtain a better adsorption effect, and there is no restriction here.

[0071] In this embodiment, the distribution trough body 42 includes a bottom provided with a flow stabilizer 45, and the flow stabilizer 45 at least partially passes through the water distribution port 41 and is arranged on the outside of the distribution trough body 42. Both sides of the flow stabilizer 45 located on the outside of the distribution trough body 42 are connected with baffles 46. The flow stabilizer 45 cooperates with the baffle 46 to form a guide flow channel, and the outlet of the guide flow channel is arranged close to the magnetic roller 11.

[0072] Specifically, the outlet of the guide flow channel is arranged at the top of the magnetic roller 11, and the conveying direction of the guide flow channel is opposite to the conveying direction of the conveyor belt 13, and the water body can be guided to the adsorption channel 31 through the guide flow channel. By setting the guide flow channel, the water outlet position of the water distribution port 41 can be extended, which is more convenient to use and adjust. Setting the outlet of the diversion flow channel at the top of the magnetic roller 11 can extend the distance that the sewage flows through the magnetic roller 11, and increase the removal rate of the magnetic roller 11 for iron impurities in the sewage. Of course, the user can also change the setting position of the outlet of the guide flow channel as needed, and there is no restriction here.

[0073] Furthermore, a water inlet pipe 47 is provided on the side wall of the distribution tank body 42, and the setting height of the water inlet pipe 47 is not lower than the setting height of the water distribution port 41, and the water inlet pipe 47 and the water distribution port 41 are respectively arranged on opposite sides of the distribution tank body 42. The water inlet pipe 47 is used to transport sewage into the distribution tank body 42. When the water inlet pipe 47 takes in water, it will disturb the water in the distribution tank body 42. By arranging the water inlet pipe 47 and the water distribution port 41 on both sides, the influence of the disturbance on the water distribution port 41 can be reduced, so that the water distribution effect of the water distribution port 41 is better.

[0074] In this embodiment, the scraper 5 includes a scraper 51 and a fixed seat 52, one end of the scraper 51 is hinged to the fixed seat 52, a first spring 53 is connected between the scraper 51 and the fixed seat 52, and the other end of the scraper 51 is closely arranged on the slag removal roller 12 by the tension of the first spring 53. The scraper 51 is pulled by the first spring 53, so that the scraper 51 can continuously clean the impurities on the conveyor belt 13, which is convenient to use and has a simple and reliable structure.

[0075] In actual use, the user can also use a rubber piece or other connector having the same function as elasticity to replace the first spring 53. Of course, the user can also use other scraping structures that can be applicable to iron impurities, which is not limited here.

[0076] In the present embodiment, a slag storage tank 6 is provided below the slag removal roller 12, and the slag storage tank 6 has a second inner cavity 61, and the slag storage tank 6 includes a top provided with a slag drop port 63 and a bottom provided with a slag discharge port 62. Specifically, the slag storage tank 6 can be partially provided in the outer shell 7, so that the slag removal roller 12 can be located in the slag drop port 63 or the slag removal roller 12 can be located above the slag drop port 63. During the manufacturing process, the slag storage tank 6 can be overlapped with the liquid storage tank 2 to reduce the manufacturing cost. When in use, the impurities transported by the conveyor belt 13 and the impurities scraped by the scraper 5 can enter the slag storage tank 6 along the slag drop port 63, and then the impurities can be discharged through the slag discharge port 62. Of course, the user can also set the slag storage tank 6 to other shapes as needed, which is not limited here.

[0077] In this embodiment, the water outlet portion includes a water outlet weir 23 disposed on the top of the liquid storage tank 2, and the water in the first inner cavity 21 can overflow into the third inner cavity 71 through the water outlet weir 23. The water in the first inner cavity 21 can evenly overflow into the third inner cavity 71 through the water outlet weir 23, reducing the disturbance caused to the first inner cavity 21 when the water flows out, so that the first inner cavity 21 can have a relatively stable water environment, and the water quality of the outlet water is better. Of course, the user can also use a collection pipe to replace the water outlet weir 23, or replace the water outlet weir 23 with other water outlet structures, which is not limited here.
