Description

Technical Field

[0001] The utility model relates to the technical field of strip cutting devices, in particular to a wet zinc smelting slag extrusion molding strip cutting mechanism. Background Art

[0002] Hydrometallurgy refers to the method of dissolving zinc in zinc roasted sand or other zinc sulfide materials and zinc sulfide concentrate in aqueous solution to extract metallic zinc or zinc compounds. It is the main method of modern zinc smelting. It consists of three major links: zinc leaching, purification from acid zinc solution, and zinc electrolytic deposition. Hydrometallurgy mainly includes roasting, leaching, leachate purification and electrolytic deposition. After the zinc is refined, it needs to be aligned for extrusion and cut into strips for use.

[0003] In the prior art, when zinc is extruded, two parallel roller cutters are rotated to extrude the zinc slag entering the roller cutters, and the gap between the roller cutters is used to extrude the zinc slag to form it, and then it is cut into strips to meet production requirements.

[0004] However, in this extrusion molding device, part of the zinc slag solidifies and adheres to the roller cutter during extrusion molding, causing the shape of the zinc strip subsequently extruded to change, which is different from the required zinc strip and cannot be used normally. Utility Model Content

[0005] The utility model aims to solve the problem that part of zinc slag solidifies and adheres to a roller cutter during extrusion molding in the background technology, and proposes a wet zinc slag extrusion molding and strip cutting mechanism.

[0006] The technical solution of the utility model is: a hydrometallurgical zinc slag extrusion molding and strip cutting mechanism, comprising:

[0007] A base frame, a feeding bin is fixedly mounted on the top of the base frame, and a motor is fixedly mounted on the side of the base frame;

[0008] The forming box comprises a box body, an extrusion roller and an extrusion disc. Both ends of the extrusion roller are rotatably connected to the box body. The extrusion roller adopts a truncated cone structure. A plurality of extrusion discs are fixedly mounted on the outer wall of the extrusion roller. The plurality of extrusion discs are evenly distributed along the extrusion roller. As the extrusion roller becomes thicker and thinner, the diameter of the extrusion discs thereon gradually decreases.

[0009] The extrusion roller shaft and the extrusion disc form a roller cutter. Multiple groups of roller cutters are arranged in the box body. The roller cutters form a group of two. The two roller cutters in the same group are placed in opposite directions and have complementary shapes. A scraper is fixedly installed on the inner wall of the box body, and a scraper is arranged between each two adjacent extrusion discs.

[0010] The end of the box body is rotatably connected to a motor via a rotating shaft, and a cutting piece is arranged inside the molding box.

[0011] Optionally, the box body is fixedly installed at the bottom of the feeding bin, and a truncated cone cavity for the rotation of the extrusion roller and the extrusion disc is opened inside the box body, and the curved surface of the extrusion disc is in contact with the truncated cone cavity.

[0012] Optionally, the extrusion discs on the two roller cutters are staggered to form an extrusion strip opening between two adjacent extrusion discs, and gears are fixedly mounted on both ends of the extrusion roller shaft, and the gears on the two roller cutters mesh with each other.

[0013] Optionally, the scraper is in an arc shape, the inner arc surface of the scraper has the same curvature as the arc surface of the gear at which it is located, and the end of the scraper is provided with a bevel.

[0014] Optionally, the cutting piece includes a separation block, a support block, an electric push rod and a strip cutting knife. The separation block and the support block are fixedly mounted on the inner wall of the box body and are located directly below the extrusion roller. A strip cutting opening is formed between the separation block and the support block. The electric push rod is fixedly mounted inside the support block, and the end of the electric push rod is fixedly connected to the strip cutting knife.

[0015] Optionally, a friction roller is rotatably connected to the side of the support block, the curved surface of the friction roller extends into the cutting opening, the friction roller contacts the zinc slag, an angle sensor is fixedly installed on the side of the friction roller, and the angle sensor is electrically connected to the electric push rod.

[0016] Optionally, the top of the feed bin is a feed port, and the zinc slag enters the feed bin and is discharged from the box body.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects:

[0018] After the utility model extrude the zinc material by rotating the extrusion roller and the extrusion disc, the zinc material moves to the position of the scraper, and the inclined surface of the scraper scrapes the zinc material from the extrusion roller and the extrusion disc, so as to avoid residual zinc material on the extrusion roller and the extrusion disc, which affects the thickness of the zinc strip after the subsequent zinc material forming.

[0019] Furthermore, through the frustum-shaped design of the extrusion roller, the excess zinc material will be squeezed toward the thin end when extruding the zinc material. Since the two roller cutters are placed in opposite directions, the excess zinc material will be squeezed to the middle of the roller cutter, thus preventing the zinc material from adhering to the box and causing accumulation.

[0020] Furthermore, the zinc slag scooped up by the shovel is introduced into the cutting mouth, and the zinc slag is used to contact the friction roller and rotate the friction roller. The angle sensor detects the number of rotations of the friction roller. When the set value is reached, the angle sensor extends the electric push rod through the controller, so that the cutting knife cuts the extruded zinc material according to the extended length of the zinc material.

[0031] Example 1

[0032] This embodiment provides a hydrometallurgical zinc slag extrusion molding and cutting mechanism. Figure 1 As shown, including:

[0033] A base frame 1 is provided, a feed bin 2 is fixedly installed on the top of the base frame 1, a motor 4 is fixedly installed on the side of the base frame 1, and a molding box 3 is arranged at the bottom of the feed bin 2; zinc slag enters from the feed bin 2 and is discharged from the bottom of the molding box 3.

[0034] like Figure 2 and 3 As shown, the forming box 3 includes a box body 31, an extrusion roller 33 and an extrusion disc 34. The end of the box body 31 is rotatably connected to the motor 4 through a rotating shaft. A cutting piece 5 is arranged inside the forming box 3. Both ends of the extrusion roller 33 are rotatably connected to the box body 31. The extrusion roller 33 adopts a truncated cone structure. A plurality of extrusion discs 34 are fixedly mounted on the outer wall of the extrusion roller 33. The plurality of extrusion discs 34 are equidistantly distributed along the extrusion roller 33. As the extrusion roller 33 becomes thinner, the diameter of the extrusion disc 34 thereon gradually decreases. The extrusion roller 33 and the extrusion disc 34 form roller cutters. A plurality of groups of roller cutters are arranged in the box body 31. The roller cutters are grouped in pairs. The two roller cutters in the same group are placed in opposite directions and have complementary shapes.

[0035] Since the extrusion roller 33 is in the shape of a truncated cone, its inclined arc surface will extrude and guide the zinc material. When extruding the zinc material, the excess zinc material will be squeezed toward the thin end. However, since the two roller cutters are placed in opposite directions, the excess zinc material will be squeezed to the middle of the roller cutters to prevent the zinc material from adhering to the box body 31 and causing accumulation and solidification, thereby affecting the capacity of the box body 31.

[0036] like Figure 2 As shown, the extrusion discs 34 on the two roller cutters are arranged alternately, and an extrusion strip opening is formed between two adjacent extrusion discs 34. The zinc material is extruded and formed by rotating the extrusion roller shaft 33 and using the extrusion discs 34 at adjacent positions. Gears 35 are fixedly installed at both ends of the extrusion roller shaft 33. The gears 35 on the two roller cutters are meshed with each other. If the diameters of the gears 35 on the two roller cutters are the same, the rotation angular velocity of the extrusion roller shaft 33 is the same.

[0037] The box body 31 is fixedly installed at the bottom of the feeding bin 2, and a truncated cone cavity 32 for rotating the extrusion roller 33 and the extrusion disc 34 is provided inside the box body 31. The curved surface of the extrusion disc 34 contacts the truncated cone cavity 32, and the extrusion disc 34 and the truncated cone cavity 32 close the extrusion strip opening.

[0038] A scraper 36 is fixedly mounted on the inner wall of the box 31, and a scraper 36 is arranged between each two adjacent extrusion discs 34. The scraper 36 is in an arc shape, and the inner arc surface of the scraper 36 has the same arc as the arc surface of the gear 35 at its position, so the inner arc surface of the scraper 36 can completely fit the gear 35, and a bevel is provided at the end of the scraper 36. After the extrusion roller 33 and the extrusion disc 34 rotate to extrude the zinc material, the zinc material moves to the position of the scraper 36, and the bevel of the scraper 36 scrapes the zinc material from the extrusion roller 33 and the extrusion disc 34, so as to avoid residual zinc material on the extrusion roller 33 and the extrusion disc 34, which affects the thickness of the zinc strip after the subsequent zinc material forming.

[0039] In this embodiment, by designing a truncated cone-shaped extrusion roller 33, the inclined arc surface of which can extrude and guide the zinc material, and when extruding the zinc material, the excess zinc material will be squeezed toward the thin end, but because the two roller cutters are placed in opposite directions, the excess zinc material will be squeezed to the middle of the roller cutters, thereby preventing the zinc material from adhering to the box body 31 and causing accumulation and solidification. After the extrusion roller 33 and the extrusion disc 34 rotate to extrude the zinc material, the zinc material moves to the position of the scraper 36, and the inclined surface of the scraper 36 scrapes the zinc material from the extrusion roller 33 and the extrusion disc 34, thereby preventing residual zinc material from existing on the extrusion roller 33 and the extrusion disc 34, which affects the thickness of the zinc strips after the subsequent zinc material forming.

[0041] Based on Example 1, this example proposes a hydrometallurgical zinc slag extrusion molding and cutting mechanism, such as Figure 3 and 4 As shown, the cutting member 5 includes a separation block 51, a support block 52, an electric push rod 55 and a strip cutting knife 56. The separation block 51 and the support block 52 are both fixedly mounted on the inner wall of the box body 31 and are located directly below the extrusion roller 33. A strip cutting opening is formed between the separation block 51 and the support block 52, and the zinc slag scooped up by the shovel 36 is introduced into the strip cutting opening.

[0042] The electric push rod 55 is fixedly mounted inside the support block 52, and the end of the electric push rod 55 is fixedly connected to the strip cutter 56. The electric push rod 55 is extended to make the strip cutter 56 cut the extruded zinc material, and the long strip zinc material is divided into short strips.

[0043] like Figure 4As shown, the side of the support block 52 is rotatably connected with a friction roller 53, the curved surface of the friction roller 53 extends into the strip cutting opening, the friction roller 53 contacts the zinc slag, and the side of the friction roller 53 is fixedly installed with an angle sensor 54, which is electrically connected to an electric push rod 55 through a controller. The zinc material moves in the strip cutting opening and contacts the friction roller 53, so that the friction roller 53 rotates, and the angle sensor 54 is used to detect the number of rotations of the friction roller 53. When the set value is reached, the angle sensor 54 extends the electric push rod 55 through the controller, so that the strip cutting knife 56 cuts the extruded zinc material.

[0044] In this embodiment, the zinc slag scooped up by the scraper 36 is introduced into the cutting mouth, and the zinc slag is used to contact the friction roller 53 to rotate the friction roller 53. The angle sensor 54 detects the number of rotations of the friction roller 53. When the set value is reached, the angle sensor 54 extends the electric push rod 55 through the controller, so that the cutting knife 56 cuts the extruded zinc material according to the extended length of the zinc material.
