Description

Technical Field

[0001] This utility model relates to the field of iron and steel metallurgy technology, and in particular to a recycling and pressing device for smelting solids. Background Technology

[0002] The recycling and pressing of smelting solids is a core step in the resource utilization of solid wastes such as slag, dust, and waste electrodes generated during the smelting process. The process usually involves first removing impurities and separating valuable metal components through pretreatment processes such as crushing, screening, magnetic separation, or flotation. Then, the pretreated materials are mixed in a specific ratio, and binders such as asphalt and resin are added to adjust their physical properties. Subsequently, the materials are fed into equipment such as briquetting machines and granulators, and pressed under set pressure and temperature conditions to form recycled materials with certain strength, density, and shapes such as spheres and blocks.

[0003] In the briquetting equipment commonly used for recycling and pressing solid materials in smelting, the molds on the core working components, such as the rollers, are mostly designed as a single piece. Since solid materials in smelting often contain hard impurities, the molds are prone to damage such as local wear, deformation, or cracking during long-term use. Because the molds are designed as a single piece, they need to be replaced as a whole, which increases the subsequent maintenance costs. Therefore, we propose a recycling and pressing device for solid materials in smelting. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a recycling and pressing device for smelting solids.

[0005] This utility model is achieved using the following technical solution: a recycling and pressing device for smelting solid materials, comprising a box body, a feeding hopper connected to the top of the box body, a protective cover fixedly connected to the front end of the box body, a motor fixedly connected to the front end of the protective cover, two symmetrically arranged fixing rods rotatably connected to the inner wall of the box body, gears fixedly connected to the surfaces of the two fixing rods and meshing between the two gears, a mold assembly provided on the surface of the fixing rods, a protrusion fixedly connected to the surface of the fixing rods, inspection ports provided at both the left and right ends of the box body, an inspection door hinged to the inner wall of the inspection port, a support provided inside the box body, the left end of the support extending to the outside of the box body, a conveyor belt provided inside the support, and a drying assembly provided at the top of the support;

[0006] The mold assembly includes an upper mold, a positioning groove at the bottom of the upper mold, a lower mold at the bottom of the upper mold, a positioning block fixedly connected to the top of the lower mold, grooves on the inner walls of both the upper and lower molds, and threaded holes on the inner walls of both the upper mold and the positioning block, with bolts threaded into the internal threads of the threaded holes.

[0007] With the above technical solution, during maintenance, the inspection door on the housing can be opened for convenient inspection and maintenance. Then, by removing the bolts, the fixing between the upper and lower molds can be removed, allowing them to be taken off individually. This facilitates the replacement of damaged parts individually, reducing maintenance costs. During installation, the groove in the upper mold is inserted into the protruding block, and the positioning block on the lower mold is inserted into the positioning groove. At the same time, the groove in the lower mold will insert into the protruding block. The upper and lower molds are then fixed with bolts to complete the installation. The operation is simple and improves installation efficiency.

[0008] As a further improvement to the above solution, the surface of the positioning block is inserted into the inner wall of the positioning groove.

[0009] The above technical solution uses a positioning block to connect with a positioning groove to limit the upper and lower molds, aligning the threaded holes and facilitating subsequent installation.

[0010] As a further improvement to the above solution, the inner wall of the groove is inserted into the surface of the protrusion.

[0011] Through the above technical solution, the protrusion blocks limit the groove, and when the fixed rod rotates, the protrusion blocks can drive the upper and lower molds to rotate synchronously.

[0012] As a further improvement to the above solution, the output end of the motor is fixedly connected to one end of the fixing rod, and the gear is located inside the protective cover.

[0013] With the above technical solution, the output end of the motor is fixedly connected to one end of one of the fixed rods. The motor drives one of the fixed rods to rotate. Because the gears on the surfaces of the two fixed rods mesh with each other, the two fixed rods rotate synchronously in opposite directions. The gear position is blocked by a protective cover to prevent workers from accidentally touching and damaging it during operation.

[0014] As a further improvement to the above solution, the drying assembly includes a fixed cover, the inner wall of which is fixedly connected with a plurality of equally spaced heating tubes, the top of which is fixedly connected with a fixed frame, and the top of the inner wall of the fixed frame is fixedly connected with a fan.

[0015] The above technical solution uses a fan to blow air towards the heating element, generating hot air which is then blown onto the surface of the solid material. This removes excess moisture from the solid material, enhances the strength of the molded solid material, and prevents breakage during transportation and subsequent use.

[0016] As a further improvement to the above solution, the bottom of the fixing cover is fixedly connected to the top of the bracket.

[0017] By using the above technical solution, heat loss can be reduced by fixing the cover to block the opening on the left side of the box.

[0018] As a further improvement to the above solution, the fixing cover is located at the left end of the housing, and the fan is located above the heating pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model sets up a mold assembly. Specifically, by removing the bolts to eliminate the fixing between the upper and lower molds, they can be removed separately, facilitating the individual replacement of damaged parts and reducing maintenance costs. During installation, the groove in the upper mold is inserted into the protruding block, and the positioning block on the lower mold is inserted into the positioning groove. At the same time, the groove in the lower mold will insert into the protruding block. The upper and lower molds are then fixed with bolts to complete the installation. The operation is simple and improves installation efficiency.

[0021] This invention incorporates a drying component, specifically a fan that blows air towards the heating element to generate hot air, which is then blown onto the surface of the solid material. This removes excess moisture from the solid material, enhances the strength of the molded solid material, and prevents breakage during transportation and subsequent use. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a recycling and pressing device for smelting solids includes a box body 1, a feeding hopper 2 connected to the top of the box body 1, a protective cover 3 fixedly connected to the front end of the box body 1, a motor 4 fixedly connected to the front end of the protective cover 3, two symmetrically arranged fixing rods 5 rotatably connected to the inner wall of the box body 1, gears 6 fixedly connected to the surface of each of the two fixing rods 5 and meshing with each other, a mold assembly 7 provided on the surface of the fixing rods 5, a protrusion 8 fixedly connected to the surface of the fixing rods 5, inspection ports 9 opened at both the left and right ends of the box body 1, an inspection door 10 hinged to the inner wall of the inspection port 9, a support 11 provided inside the box body 1, the left end of the support 11 extending to the outside of the box body 1, a conveyor belt 12 provided inside the support 11, and a drying assembly 13 provided at the top of the support 11.

[0032] The mold assembly 7 includes an upper mold 701, with a positioning groove 702 at its bottom and a lower mold 703 at its bottom. A positioning block 704 is fixedly connected to the top of the lower mold 703. Both the upper mold 701 and the lower mold 703 have grooves 705 on their inner walls and threaded holes on their inner walls. Bolts 706 are threaded into the threaded holes. By removing the bolts 706, the fixing between the upper mold 701 and the lower mold 703 can be removed, allowing them to be removed individually for easy replacement of damaged parts and reducing maintenance costs. During installation, the groove 705 in the upper mold 701 is inserted into the protrusion 8, and the positioning block 704 on the lower mold 703 is inserted into the positioning groove 702. At the same time, the groove 705 in the lower mold 703 will insert into the protrusion 8. The upper mold 701 and the lower mold 703 are then fixed in place by the bolts 706 to complete the installation. The operation is simple and improves installation efficiency.

[0033] The surface of the positioning block 704 is inserted into the inner wall of the positioning groove 702. When the positioning block 702 is inserted into the interior of the positioning groove 702, the upper mold 701 and the lower mold 703 are positioned, which facilitates subsequent fixation.

[0034] The inner wall of the groove 705 is inserted into the surface of the protrusion 8. The protrusion 8 limits the upper mold 701 and the lower mold 703, so that the fixed rod 5 will drive the upper mold 701 and the lower mold 703 to rotate synchronously during rotation.

[0035] The output end of the motor 4 is fixedly connected to one end of the fixed rod 5, and the gear 6 is located inside the protective cover 3.

[0036] The drying assembly 13 includes a fixed cover 1301. Several heating tubes 1302 are fixedly connected to the inner wall of the fixed cover 1301 at equal intervals. A fixed frame 1303 is fixedly connected to the top of the fixed cover 1301. A fan 1304 is fixedly connected to the top of the inner wall of the fixed frame 1303. The fan 1304 blows air to the heating tubes 1302 to form hot air and blows it onto the surface of the solid material to remove excess moisture from the solid material, enhance the strength of the molded solid material, and prevent breakage during transportation and subsequent use.

[0037] The bottom of the fixed cover 1301 is fixedly connected to the top of the bracket 11.

[0038] The fixed cover 1301 is located at the left end of the housing 1, and the fan 1304 is located above the heating tube 1302.

[0039] The implementation principle of the recycling and pressing device for smelting solids in this embodiment is as follows: First, the motor 4 is started, driving one of the fixed rods 5 to rotate. Because the gears 6 on the surfaces of the two fixed rods 5 mesh with each other, the two fixed rods 5 rotate synchronously in opposite directions. Then, the pre-treated smelting solids are added into the interior of the housing 1 through the feed hopper 2. The solids fall between the two mold components 7, and the two upper molds 701 and lower molds 703 work together to press the solids into a spherical shape. The formed solids fall above the conveyor belt 12, which then conveys them to the drying component 13. Heat is generated by several heating tubes 1302, and a fan 1304 blows air towards the heating tubes 1302, forming hot air that is then blown onto the surface of the solids to remove excess moisture, enhance the strength of the formed solids, and prevent breakage during transportation and subsequent use. The dried and formed solids are output from the end of the conveyor belt 12. When the upper mold 701 or lower mold 703 is damaged during long-term use, the inspection door 10 on the housing 1 is opened. Then, by removing bolt 706, the fixing between the upper mold 701 and the lower mold 703 can be removed, allowing them to be taken off separately. This facilitates the individual replacement of damaged parts and reduces maintenance costs. During installation, the groove 705 in the upper mold 701 is inserted into the protrusion 8, and the positioning block 704 on the lower mold 703 is inserted into the positioning groove 702. At the same time, the groove 705 in the lower mold 703 will be inserted into the protrusion 8. The upper mold 701 and the lower mold 703 are fixed by bolt 706 to complete the installation. The operation is simple and improves the installation efficiency. The protrusion 8 limits the upper mold 701 and the lower mold 703, so that the rotation of the fixing rod 5 will drive the upper mold 701 and the lower mold 703 to rotate synchronously.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
