Description

Technical Field

[0001] The invention relates to the technical field of slag screening and classification, and in particular to a device for intelligently classifying and extracting residual metals in slag. Background Art

[0002] Slag is a common waste material produced by steel casting manufacturers. It is mainly composed of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal. In the past, waste slag was usually regarded as waste. However, with the continuous development of technology and people's increasing demand for resources, waste slag has been found to have many emerging application fields and show unlimited potential. With people's attention to environmental protection and demand for resource utilization, a copper smelting slag treatment device and method disclosed in Chinese patent CN109136577B can be used to treat copper smelting slag. The processing device passes the smelting slag through a large chute to filter out the large stones to the upper end of the conveyor belt, and transports it through the conveyor belt. During the transportation process, the stones with metal on the upper end of the large slag are picked out, screened out by the pushing device, placed in the crusher, and crushed by the crusher. The crushed slag is transported to the inside of the ore washing machine for cleaning; the sewage is filtered through the sewage filtering device and reused to save resources; the washed slag is screened through a vibrating screen to be divided into large and small slag, which enter the AM30 jig and trapezoidal jig respectively to separate the copper from the waste slag.

[0003] Therefore, the recycling of slag has become an important task, and slag ball mill is also a commonly used slag processing equipment. It is usually crushed by a ball mill and then screened. The common screening operation is to use a screen to screen the material falling from the discharge of the ball mill, and the residual metal in the slag is screened out by a simple vibration method. However, it is difficult to evenly spread the material on the surface of the screen, so that the fallen material occupies a smaller area of ​​the screen and is easily stacked together, which leads to poor screening efficiency and affects the recycling efficiency.

When the offset is completed, the hinged auxiliary plate 11 can be turned over and lowered, so as to facilitate the movement of the screened slag material to the surface of the conveyor belt 1002;

[0052] At this time, the conveyor belt 1002 is started to work, and a classification box 1003 is provided on one side wall where the two support plates 1001 are close to each other, so that the metal materials on the surface of the conveyor belt 1002 can fall into the classification box 1003 through the conveyor belt 1002. At this time, a magnetic attraction layer is provided on the outer surface of the conveyor belt 1002, and a partition 1004 is fixedly connected to the inner wall of the classification box 1003, and a scraper 1005 is fixedly connected to the one side wall where the two support plates 1001 are close to each other, and at the same time, the upper surface of the scraper 1005 is in contact with the outer surface of the conveyor belt 1002, so that the magnetic attraction layer can adsorb the iron in the metal, so that the stainless steel falls on one side of the partition 1004, and the scraper 1005 is used to scrape the adsorbed iron, so that the iron falls on the other side of the partition 1004, so as to achieve intelligent classification and storage of iron and stainless steel in the metal for easy access;

[0054] Example 4, please refer to Figure 8-9 A through hole 1 is formed through the upper surface of the limit shell 603, and the limit shell 603 is slidably connected with a resist column 16 through the through hole 1. The lower end of the resist column 16 abuts against the surface of the end of the connecting rod 601, and a through hole 2 is formed through the side of the resist column 16, and the resist column 16 is slidably connected with a connecting plate 17 through the through hole 2. A third spring 18 is sleeved on the surface of the resist column 16, and the two ends of the third spring 18 are respectively fixedly connected to the upper surface of the limit shell 603 and the lower surface of the connecting plate 17, and the end of the connecting plate 17 is fixedly connected to a piston rod 19, and the top of the piston rod 19 is fixedly connected to a piston, and the surface of the piston is slidably sleeved with a piston cylinder 20, and the surface of the piston cylinder 20 is fixedly installed with an inlet pipe 21 and a water outlet pipe 22 through a one-way valve, and the end of the water outlet pipe 22 away from the piston cylinder 20 is fixedly connected to the support seat 2, and an atomizing nozzle is fixedly installed on the top of the water outlet pipe 22.

[0055] When the electric push rod 604 pushes the screening plate 602 to slide left and right and shake up and down, the connecting rod 601 is displaced up and down simultaneously along the groove wall of the shaking groove 7. Therefore, the connecting rod 601 will continuously press the support column 16 in the process of continuously displacing up and down relative to the limit shell 603, so as to cooperate with the downward elastic restoring force applied by the third spring 18, so as to drive the support column 16 together with the connecting plate 17 and the piston rod 19 to move back and forth up and down.

[0056] Working principle: first, start the ball mill body 1, put the slag material into the ball mill body 1 through the feed hopper 3, crush it through a number of steel balls of different sizes, and transport the crushed slag material to the surface of the screening plate 602 through the discharge hopper 4, then start the electric push rod 604, under the restriction of the support frame 5, the support seat 2 and the shaking groove 7, the electric push rod 604 can push the screening plate 602 to slide left and right, and under the guidance of the wavy shaking groove 7, the screening plate 602 can shake left and right during the vibration process, so as to avoid the stacking of the fallen materials, and the materials on the surface of the screening plate 602 can be flattened by shaking left and right;

[0057] Then, the slag material on the surface of the screening plate 602 is blocked by the two first baffles 605 and the second baffle 606 to prevent the required slag material from falling off the edge, and the water flow in the water tank 12 is transported to the bottom inner wall of the support frame 5 through the conveying pipe 13, and the screened waste is discharged through the discharge hole 14 by the water flow, which is convenient for cleaning the waste. At the same time, a collection box 15 is correspondingly installed through one side wall of the support seat 2, so that the water flow and the waste can be collected, which is convenient for the reuse of the water flow;

[0058] Then, during the screening process, the second spring 807 is used to press the two slide bars 804 to keep the screening plate 602 balanced. When the screening plate 602 synchronously drives the connecting plate 801 to move to the left, the inclined surface of the extrusion block 808 is synchronously driven to squeeze the connecting bar 806, so that the connecting bar 806 drives the slide bar 804 to squeeze downward, so that the screening plate 602 can be tilted and offset in the shaking direction, so that the material can better move to the edge of the screening plate 602.

[0059] Then, after the screening is completed and the water flow in the support frame 5 is drained, the two second baffles 606 in the clamped state are pulled out, and the electric push rod 604 is contracted at this time, so that the screening plate 602 moves to the left, so that the screening plate 602 is tilted and offset in the direction of the conveyor belt 1002. When the offset is completed, the hinged auxiliary plate 11 can be turned over and lowered, so as to facilitate the movement of the screened slag material to the surface of the conveyor belt 1002;

[0060] Then, the conveyor belt 1002 is started to work, so that the metal materials on the surface of the conveyor belt 1002 can fall into the classification box 1003 through the conveyor belt 1002, and the iron in the metal is adsorbed by the magnetic layer, so that the stainless steel falls on one side of the partition 1004, and the adsorbed iron is scraped off by the scraper 1005, so that the iron falls on the other side of the partition 1004, thereby achieving intelligent classification and storage of iron and stainless steel in the metal.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
