Description

Technical Field

[0001] The invention relates to the technical field of zinc slag recovery, and in particular to a zinc slag recovery device for improving the utilization rate of zinc ingots. Background Art

[0002] In the electroplating, hot-dip galvanizing, zinc smelting, battery manufacturing and other industries, zinc slag will be produced. If the zinc slag is not treated, it will not only cause a waste of resources, but also pollute the environment. Therefore, the market currently uses recycling devices to recycle the zinc slag, so that the zinc slag can be turned into zinc ingots for the convenience of reuse of the zinc slag.

[0003] For example, the patent name disclosed in the prior art with the announcement number "CN109022804B" is "A high-efficiency zinc slag recovery and processing device", which discloses the use of a driving structure in conjunction with a transmission structure, which is convenient for driving the filter structure to rotate inside the storage box, thereby increasing the contact area between the filter structure and the slag liquid, improving the filtering effect of the slag liquid, and effectively preventing the filter structure from being blocked, thereby improving the stability of use. The driving structure is used in conjunction with the cleaning structure to facilitate cleaning the slag liquid inside the filter structure, avoiding blockage of the filter structure, thereby improving the cleaning quality. At the same time, a sealing structure is provided between the cover plate and the storage box, making the installation and removal of the cover plate more convenient and quick. The patent name disclosed in the prior art with the announcement number "CN221182977U" is "A high-efficiency zinc slag recovery and processing device", which discloses When using a crusher to crush industrial zinc slag waste, first, the industrial zinc slag waste needs to be placed in a feed box, and then the drive motor is started. The output end of the drive motor will drive the drive shaft on one side to rotate through the first transmission belt, and the drive shaft will drive the drive shaft on the other side to rotate through the drive wheel on the outer wall. The drive shaft on the other side drives the positioning shaft to rotate through the second transmission belt, and the positioning shaft will drive multiple feed plates on the outer wall to rotate, so that the industrial zinc slag waste can be evenly transported to the crusher. The industrial zinc slag waste enters the crusher and falls between the two crushing rollers through the guide plate. The two drive shafts 7 rotate relative to each other under the action of two meshing drive wheels, thereby driving the two crushing rollers to rotate relative to each other, and the industrial zinc slag waste is crushed. The crushed industrial zinc slag waste will be discharged through the discharge port and discharge frame on one side of the bottom end of the lower shell of the crusher.

[0004] The zinc slag recovery device in the above-mentioned prior art simply recovers the zinc slag by crushing and filtering. The iron impurities in the zinc slag cannot be removed during the filtering process, thus affecting the purity of the recovered zinc slag and further affecting the utilization rate of the subsequent zinc ingots. Therefore, we propose a zinc slag recovery device that improves the utilization rate of zinc ingots in order to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a zinc slag recycling device for improving the utilization rate of zinc ingots, so as to solve the problem proposed in the above background technology that the existing zinc slag recycling devices on the market only simply recycle zinc slag through crushing and filtering, and iron impurities in the zinc slag cannot be removed during the filtering process, thus affecting the purity of zinc slag recycling and then the utilization rate of zinc ingots in the later stage.

[0012] Preferably, the installation component includes screws. Two inclined guide plates are connected to the inside of the outer shell through screws. The length of the guide plate on the left side is less than the length of the guide plate on the right side.

[0013] Preferably, self-control frames with a "7" - shaped structure are installed on both the left and right sides of the moving frame.

[0014] Preferably, the installation component includes a rotating rod. Both of the two inclined flow guiding plates are rotatably connected to the interior of the outer casing through the rotating rod. The front end of the rotating rod penetrates through the front side surface of the outer casing and is connected to the convex plate. A scroll spring is nested on the outer side of the front end of the rotating rod. One end of the scroll spring is connected to the front side surface of the outer casing.

The specific contents are as follows:

[0017] (1) By the combined use of the rotating magnetic separation cylinder and the stationary magnetic system, the filtered zinc slag can be further screened, and the iron impurities in the filtered zinc slag can be adsorbed and removed, thereby further improving the purity of the recycled zinc slag, increasing the utilization rate of the later zinc ingots, and reducing the waste of zinc resources;

[0019] (3) The crushing component can drive the moving frame to move back and forth reciprocally through the single - rotation reciprocating screw rod, so that the moving frame drives the filter frame to move back and forth reciprocally through the clamping block, facilitating the improvement of the filtering efficiency and effect of the filter frame. At the same time, when the filter frame drives the filter plate to move back and forth reciprocally, repulsive forces are generated by the lower magnet block corresponding to the three upper magnet blocks in a row in turn. Therefore, while the filter plate moves back and forth reciprocally, it can also move up and down reciprocally, further improving the filtering efficiency and effect of the filter plate;

[0020] (4) Through the setting of the support member, the clamping block can be separated from the clamping groove, so that the filter frame can be pulled out of the outer casing, facilitating the cleaning and replacement operations of the filter frame. Brief Description of the Drawings

Detailed Description of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer toFigures 1 - 10 , the present invention provides the following technical solutions:

[0034] Embodiment 1: The zinc slag recycling device for improving the utilization rate of zinc ingots in this embodiment can further screen the filtered zinc slag, adsorb and remove iron impurities in the filtered zinc slag, thereby further improving the purity of the recycled zinc slag, increasing the utilization rate of zinc ingots in the later stage, and reducing the waste of zinc resources. The specific structure is as shown in the attached Figures 1 - 5 and the attached Figure 6 and the attached Figure 8 As shown in the figure, it includes a housing 1 and a crushing component 9 installed through the upper part of it. The discharge port 5 at the bottom of the housing 1 is connected to a rotary kiln 6, and the rotary kiln 6 is connected to a condenser 8 through a conveying pipe 7. A filter frame 2 is slidably connected to the housing 1 corresponding to the lower part of the crushing component 9. A deflector 10 is installed in the housing 1 corresponding to the lower part of the filter frame 2 through a mounting component. A magnetic separation cylinder 14 and a magnetic system 141 are installed in the housing 1 corresponding to the lower part of the deflector 10, and the magnetic system 141 is arranged inside the magnetic separation cylinder 14.

[0035] The rear end of the magnetic separation cylinder 14 is rotatably connected to the rear side surface of the housing 1. The front end of the fan-shaped magnetic system 141 passes through the front side surface of the magnetic separation cylinder 14 and is fixedly connected to the front side surface of the housing 1. The inside of the magnetic separation cylinder 14 is hollow. A partition plate is installed in the housing 1 below the magnetic separation cylinder 14. An iron outlet 12 is installed at the bottom of the housing 1 on the right side of the partition plate. The arc length of the magnetic system 141 is less than half of the circumference of the magnetic separation cylinder 14. The front end of the crushing component 9 is connected to a single-spiral reciprocating screw 3. The thread directions of the two single-spiral reciprocating screws 3 on the outside are opposite. A moving frame 4 is threadedly connected through the outside of the two single-spiral reciprocating screws 3. Sleeve rods 203 are installed at the four corners inside the filter frame 2. The four sleeve rods 203 respectively pass through the four corners inside the filter plate 201. A return spring 204 is sleeved below the sleeve rod 203. The elastic force of the return spring 204 is greater than the gravity of the zinc slag above the filter plate 201. Two groups of lower magnet blocks 202 are symmetrically installed on the upper surface of the filter frame 2. Two rows of upper magnet blocks 101 are symmetrically installed in the housing 1 corresponding to the upper part of the filter frame 2. One row has three upper magnet blocks 101. The corresponding surfaces of the lower magnet blocks 202 and the upper magnet blocks 101 are like-named magnetic poles. The mounting component includes screws. The two inclined deflectors 10 are connected to the inside of the housing 1 through screws. The length of the left deflector 10 is less than the length of the right deflector 10.

[0036] First, move the entire zinc slag recycling device into the working area. After reaching the working area, grab the zinc slag in the zinc pot through an external gripper, and then the gripper pours the zinc slag into the housing 1 through the feed inlet on the housing 1. At the same time, connect the rear end of one of the crushing components 9 to an external motor, and the motor drives one of the crushing components 9 to rotate. One of the crushing components 9 drives the other crushing component 9 to rotate through two externally meshing transmission gears on the outside, so that the two crushing components 9 rotate simultaneously to crush the zinc slag, breaking the large zinc slag into small pieces. At this time, the crushed zinc slag falls onto the filter plate 201 in the lower filter frame 2 and is preliminarily filtered through the filter plate 201, and then is secondarily filtered through the bottom surface of the filter frame 2, leaving the impurities in the filter frame 2. The filtered zinc slag is guided by two inclined guide plates 10 and falls onto the left side of the magnetic separation cylinder 14, making the zinc slag come into good contact with the left side of the magnetic separation cylinder 14. At this time, the motor behind the magnetic separation cylinder 14 drives the magnetic separation cylinder 14 to rotate, and the magnetic system 141 remains stationary. Therefore, the left side of the magnetic separation cylinder 14 always has magnetism and can adsorb the iron impurities in the zinc slag. When the magnetic separation cylinder 14 drives the iron impurities to rotate to the right side, the right side of the magnetic separation cylinder 14 is far from the magnetic system 141 and has no magnetism, causing the iron impurities on the right side of the magnetic separation cylinder 14 to automatically fall downward into the iron outlet 12 for collection, and the zinc slag falls into the discharge port 5. Thus, the zinc slag is mechanically recycled and processed well. Then, the zinc slag in the discharge port 5 enters the rotary kiln 6 for thermal recovery processing. The zinc slag is heated at a high temperature in the rotary kiln 6, and the zinc compound is reduced to zinc vapor. Then, the zinc vapor is transported to the condenser 8 through the cooperation of the air extraction pump and the delivery pipe 7 for condensation and recovery. Since this part is prior art, no detailed introduction will be made here, thereby improving the recovery rate and the utilization rate of zinc ingots.

[0037] When the two crushing components 9 rotate, they can drive the single - rotation reciprocating screw rod 3 connected to the front end to rotate. Since the thread directions on the outside of the two single - rotation reciprocating screw rods 3 are opposite, when the two single - rotation reciprocating screw rods 3 rotate in different directions, they can also drive the moving frame 4 thread - connected to the outside to move back and forth. At this time, the clamping block 42 below the moving frame 4 is inserted into the clamping groove 205, so that the moving frame 4 drives the filter frame 2 to move back and forth, enabling the filter frame 2 and the filter plate 201 to shake - filter the zinc slag back and forth well, which can improve the filtering efficiency and effect of the filter frame 2 and the filter plate 201. At the same time, when the filter plate 201 moves back and forth, the lower magnet block 202 above the filter plate 201 will sequentially correspond to the three upper magnet blocks 101 in a row to generate repulsive forces, so that the filter plate 201 can not only shake back and forth but also move up and down reciprocally while shaking back and forth, thereby further improving the filtering efficiency and effect of the filter plate 201. Therefore, the purity of zinc slag recycling can be improved, the utilization rate of later zinc ingots can be increased, and zinc resource waste can be reduced.

[0038] Example 2: The zinc slag recycling device for improving the utilization rate of zinc ingots in this example, on the basis of Example 1, can avoid a large amount of the filtered zinc slag from falling, resulting in incomplete magnetic separation of the magnetic separation cylinder 14. Thus, the magnetic separation effect of the magnetic separation cylinder 14 can be improved, the purity of the recycled zinc slag can be further increased, and the utilization rate of the subsequent zinc ingots can be improved. The specific structure is referred to in the appendix Figure 4 and the appendix Figure 6 as well as the appendix Figures 9 - 10 As shown in the figure, self - control frames 13 with a "7" - shaped structure are installed on both the left and right sides of the moving frame 4. The installation component includes a rotating rod 11. Two inclined guide plates 10 are rotatably connected to the inside of the outer shell 1 through the rotating rod 11. The front end of the rotating rod 11 penetrates through the front side of the outer shell 1 and is connected to a convex plate 112. A scroll spring 111 is nested on the outer side of the front end of the rotating rod 11. One end of the scroll spring 111 is connected to the front side of the outer shell 1. The rear upper surface of the convex plate 112 is inclined. A self - control frame 13 is arranged at the rear of the convex plate 112. The convex plate 112 forms a rotating structure through the self - control frame 13

[0039] When the moving frame 4 moves forward, it will drive the self - control frame 13 to move forward together. At this time, the lower end of the self - control frame 13 contacts the upper surface of the convex plate 112. Since the rear upper surface of the convex plate 112 is inclined, when the self - control frame 13 continues to move forward, it will exert a downward thrust on the convex plate 112. At this time, the convex plate 112 drives the rotating rod 11 to rotate, and the scroll spring 111 stores energy. The rotating rod 11 drives the guide plate 10 to rotate by a certain angle, so that the guide plate 10 rotates from an inclined state to a horizontal state. At this time, the speed of the zinc slag falling downward on the guide plate 10 is slower, so the amount of zinc slag falling downward decreases. When the moving frame 4 and the self - control frame 13 move backward together, by the same token as described above, the scroll spring 111 automatically drives the rotating rod 11 to rotate reversely and reset through the stored energy, so that the rotating rod 11 drives the guide plate 10 to rotate reversely and reset. At this time, the guide plate 10 is inclined, so that the zinc slag on the guide plate 10 can fall downward well, avoiding the zinc slag from accumulating on the horizontal guide plate 10 for a long time and affecting the subsequent magnetic separation operation. By operating repeatedly like this, the guide plate 10 can intermittently control the falling amount of the zinc slag. Therefore, it is avoided that the zinc slag accumulates and falls, resulting in incomplete magnetic separation of the magnetic separation cylinder 14, and then the magnetic separation effect of the magnetic separation cylinder 14 can be improved, the purity of the recycled zinc slag can be further increased, and the utilization rate of the subsequent zinc ingots can be improved

[0040] Example 3: The zinc slag recycling device for improving the utilization rate of zinc ingots in this example, on the basis of Example 1, is convenient for separating the filter frame 2 from the outer shell 1, so as to facilitate the cleaning and replacement of the filter frame 2. The specific structure is referred to in the appendix Figures 7 - 8As shown, the lower part of the moving frame 4 is connected to the filter box 2 through a connecting component. The connecting component includes support members 41 symmetrically installed under the moving frame 4. The support members 41 are composed of manual telescopic rods and connecting springs sleeved outside the manual telescopic rods. Moreover, a clamping block 42 is installed at the lower end of the support member 41. Two clamping grooves 205 are symmetrically opened on the upper surface of the front end of the filter box 2. The lower end of the clamping block 42 passes through the through groove opened on the upper surface of the outer housing 1 and is inserted into the clamping groove 205. And the two clamping blocks 42 are connected by a connecting rod 43. When it is necessary to pull out the filter box 2 from the outer housing 1, at this time, manually pull the connecting rod 43 upward. The connecting rod 43 drives the two clamping blocks 42 to move upward together. At this time, the clamping block 42 squeezes the support member 41, causing the manual telescopic rod in the support member 41 to contract, and the connecting spring sleeved outside the manual telescopic rod stores energy. When the clamping block 42 rises to a certain height and separates from the clamping groove 205, at this time, the filter box 2 can be manually pulled forward, and then the sliding blocks on the left and right sides of the filter box 2 slide out from the sliding grooves on the left and right sides of the outer housing 1. Therefore, the filter box 2 can be cleaned and replaced to meet different usage requirements, thereby completing a series of work.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
