Description

Technical Field

[0001] The utility model relates to the technical field of slag waste separation, in particular to a slag waste separation tool. Background Art

[0002] Before feeding the melting furnace, the materials need to be made into bricks of a certain strength. In addition to the washed filter cake, the raw materials for brick making also contain a certain amount of slag. The main function of the slag is to adjust the proportion of each component in the ingredients to ensure that the formed bricks have a certain strength. In addition to containing the specified components, the actual hazardous waste slag often contains a lot of residues from the incineration process, such as scrap iron blocks, plastic sheets, glass sheets, etc. These materials are not only unable to be formed into bricks, but also cause damage to the forming machine. Therefore, the slag must be screened before mixing to remove large pieces of material.

[0003] For example, a converter slag and iron waste separation device with publication number CN208357198U has separation plates equidistantly arranged on the inner wall of the support frame from top to bottom, a sieve plate is arranged in the middle of the separation plate, and a material blocking plate is rotatably connected to the end of the separation plate.

[0004] The above-mentioned slag iron waste is separated from the slag by the setting of the separation plate and the sieve plate. The separation plate and the sieve plate are set to be tilted downward. The slag on the separation plate and the sieve plate will slide down due to its own weight. The slag stays on the sieve plate for a short time, and the separation time of the slag and the waste is short. The slag and the waste cannot be completely separated. Incomplete separation will affect the normal processing in the later stage. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , the utility model provides the following technical solutions:

[0024] A slag waste separation tooling comprises an upper filter plate 11 and a baffle 14. The baffle 14 is connected to the inner wall of the upper shell 1 through a shaft. The upper filter plate 11 is installed inside the upper shell 1. The right side of the baffle 14 is slidably connected to the lower filter plate 13. The left side of the baffle 14 is slidably connected to the limit rod 16. The limit rod 16 limits the baffle 14 to prevent the baffle 14 from rotating downward due to gravity. The upper filter plate 11 and the baffle 14 are located inside the lower shell 2 and the upper shell 1. The lower shell 2 is rotatably connected to a push rod 12. The lower filter plate 13 is located below the push rod 12. The lower filter plate 13 is lifted and lowered by the push rod 12. A pulley assembly 4 is provided between the other end of the reciprocating screw 20, the outer end of the push rod 12 and the auger shaft.

[0025] The rotation of the auger shaft drives the push rod 12 to rotate synchronously. When the push rod 12 rotates to gradually contact the lower filter plate 13, it pushes the lower filter plate 13, thereby moving the lower filter plate 13 upward. When the push rod 12 rotates and gradually separates from the lower filter plate 13, the push rod 12 separates from the lower filter plate 13 and no longer limits it. At this time, the lower filter plate 13 moves downward by its own weight, thereby causing the lower filter plate 13 to vibrate up and down. The waste and slag are better separated by vibration, so that the waste is completely filtered out.

[0026] The lower shell 2 is mounted on the frame 3, the upper shell 1 is mounted on the lower shell 2, the dust removal port 10 and the feed port 9 are mounted on the upper shell 1, the fine material discharge port 7 and the coarse material discharge port 8 are provided at the bottom of the upper shell 1, the fine material discharge port 7 is located on the right side of the coarse material discharge port 8, the motor 5 is mounted on the frame 3, the bearing seat 6 is mounted on the frame 3, the output end of the motor 5 is mounted with an auger shaft, the bearing seat 6 is rotatably connected to the auger shaft, the lower end of the auger shaft is in contact with the upper filter plate 11, and the upper filter plate 11 is provided with a through hole.

[0027] The slag is poured into the inside of the feed port 9, and the slag enters the upper part of the auger shaft inside the upper shell 1. The motor 5 is running to rotate the auger shaft, and the rotation of the auger shaft pushes the slag. At the same time, part of the waste can fall through the upper filter plate 11 during the pushing process, and the waste slides to the position of the fine material discharge port 7 and is discharged through the fine material discharge port 7. The slag gradually moves to the side of the through hole. After the slag moves to the through hole position, it falls through the through hole onto the lower filter plate 13 on the baffle 14. The lower filter plate 13 is filtered twice, and the screened waste passes through the lower filter plate 13 and falls onto the fine material discharge port 7, thereby realizing the collection of the waste.

[0028] A pass electromagnet 15 is installed on the left side of the baffle 14 and the inside of the lower shell 2, a return spring is installed between the limit rod 16 and the upper filter plate 11, a contact 17 is installed on the top of the limit rod 16 and the inside of the upper shell 1, an inclined through slot 19 is provided inside the limit rod 16, the distance between the upper and lower contacts 17 is equal to the lifting distance of the limit rod 16, the contact 17 is electrically connected to the pass electromagnet 15, the bottom of the limit rod 16 is inserted into the inside of the baffle 14, the internal rotation of the upper shell 1 is connected with a reciprocating screw rod 20, the end of the reciprocating screw rod 20 close to the limit rod 16 is threadedly connected to the inner filter plate 18, the inner filter plate 18 contacts the inclined edge of the through slot 19, the gravity of the end of the baffle 14 away from the lower filter plate 13 is greater than the total weight of the lower filter plate 13 and the waste residue, and a power-off delay time relay is provided on the circuit of the pass electromagnet 15.

[0029] After filtration, the remaining slag remains on the top of the lower filter plate 13. The rotation of the pulley assembly 4 drives the reciprocating screw 20 to rotate synchronously. The rotation of the reciprocating screw 20 causes the inner filter plate 18 to move left and right. When the inner filter plate 18 moves to the left and into the through groove 19, the inner filter plate 18 has covered the through hole. The inner filter plate 18 continues to move to the left, causing the limit rod 16 to gradually move upward. When the limit rod 16 moves to separate from the baffle 14, the gravity of the baffle 14 rotates to the left. During the counterclockwise rotation of the baffle 14, the waste residue on the lower filter plate 13 rolls toward the side close to the coarse material discharge port 8, and the waste residue slides into the inside of the coarse material discharge port 8 and is discharged through the coarse material discharge port 8. During the upward movement of the limit rod 16, the top contact 17 is driven to move upward synchronously. When the two contacts 17 contact each other, After the limit rod 16 is inserted into the inside of the baffle 14, the power-off delay time relay will de-energize the electromagnet 15 to prevent the baffle 14 from rotating due to gravity after the contacts 17 are out of contact, so that the limit rod 16 is steadily inserted into the inside of the baffle 14.

[0030] The slag screened out is used as the raw material for forming bricks and is mixed in proportion. The waste on the lower filter plate 13 continues to be screened for the second time. The large pieces of material screened out (generally scrap iron) are collected and sent to the steel plant, and the small pieces of material screened out (generally waste plastic and small pieces of scrap iron) are sent to the melting furnace to adjust the iron content in the furnace and lower the melting point of the melting furnace.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
