Description

Technical Field

[0001] This utility model relates to the field of chemical mixing technology, and in particular to a mixing device for proportioning and mixing recycled materials and new raw materials. Background Technology

[0002] In the production of castings for high-end equipment such as chemical pumps, core components, such as pump casings and impellers, must be cast using corrosion-resistant alloys. These alloys have extremely stringent requirements for chemical composition; even slight deviations in trace elements can lead to a sharp decline in the product's corrosion resistance. Furthermore, the cost of smelting these alloys is extremely high, with new metal raw materials such as nickel, molybdenum, and chromium accounting for the vast majority of direct material costs.

[0003] To reduce costs, most foundries use mixing devices to remelt recycled materials, such as risers, scrap parts, and machining chips, after mixing them with new materials. However, most mixing devices only achieve physical accumulation rather than uniform mixing when mixing recycled materials with new materials. High-density materials and lightweight recycled materials are prone to stratification, which can lead to uneven composition and asynchronous melting after being fed into the furnace, prolonging melting time and increasing energy consumption.

[0004] Therefore, how to provide a mixing device for blending recycled materials and new raw materials, which can improve the uniformity of the mixture, facilitate its subsequent use in the furnace, reduce smelting time, and lower costs, is an urgent technical problem to be solved. Utility Model Content

[0005] This invention provides a mixing device for proportioning recycled materials and new raw materials, solving the problem that most mixing devices only achieve physical accumulation rather than uniform mixing when mixing recycled materials and new raw materials. High-density raw materials and lightweight recycled materials are prone to stratification, which can lead to uneven composition and asynchronous melting after being put into the furnace, prolonging the melting time and increasing energy consumption.

[0006] This utility model provides a mixing device for proportioning recycled materials and new raw materials, comprising: a frame, the frame being hinged to a support frame via a swing shaft, the support frame being rotatably connected to a mixing cylinder via a rotating shaft, the rotating shaft being positioned at the center of the top and bottom ends of the mixing cylinder, the top end of the mixing cylinder having a first feed inlet and a second feed inlet, the bottom end of the mixing cylinder having a discharge port, the inner wall of the mixing cylinder being provided with a lifting liner, a motor being mounted on the support frame, the motor being connected to the mixing cylinder via a first transmission assembly, the first transmission assembly being used to transmit the power of the motor to the mixing cylinder to drive the mixing cylinder to rotate around the rotating shaft, the motor being connected to the support frame via a second transmission assembly, the second transmission assembly being used to transmit the power of the motor to the support frame to drive the support frame to swing around the swing shaft.

[0007] In one possible implementation, the first transmission assembly includes a driving gear, a transmission rod, a first driven gear, a second driven gear, and a gear ring. The driving gear is mounted on the rotating shaft of the motor. The two ends of the transmission rod are respectively connected to the first driven gear and the second driven gear. The transmission rod is rotatably mounted on the fixed rotating cylinder of the support frame. The first driven gear meshes with the driving gear, and the second driven gear meshes with the gear ring. The gear ring is mounted on the outer wall of the mixing cylinder.

[0008] In one possible implementation, the second transmission assembly includes a drive pulley, a driven pulley, a connecting rod, a slider, and a slide rail. The drive pulley is mounted on the rotating shaft of the motor and is belt-connected to the driven pulley. A rotating rod is disposed inside the driven pulley and is rotatably mounted on the fixed frame of the support frame. One end of the rotating rod is fixedly connected to the connecting rod, and the other end of the connecting rod is hinged to the slider. The slider is mounted on the slide rail, and the slide rail is mounted on the frame.

[0009] In one possible implementation, a wheel is provided at one end of the rotating rod extending out of the fixed frame, and a placement groove is provided inside the wheel, with the connecting rod at least partially located in the placement groove.

[0010] In one possible implementation, the lifting liner is in multiple sets, which are spirally arranged and uniformly disposed on the inner wall of the mixing cylinder.

[0011] In one possible implementation, the lifting liner is provided with a plurality of clearance openings, which are used to prevent material from clogging the lifting liner.

[0012] In one possible implementation, the free ends of the two rotating shafts at the top and bottom of the mixing cylinder are both connected to the support frame via bearing seats.

[0013] In one possible implementation, a reinforcing ring is provided on the outer wall of the mixing cylinder, and the reinforcing ring is positioned above the toothed ring. A limit frame is provided on the support frame, and a roller is rotatably provided on the limit frame, with the roller abutting against the reinforcing ring.

[0014] In one possible implementation, the reinforcing ring is provided with a limiting ring groove, the limiting ring groove being used to accommodate the roller, and the roller rotating within the limiting ring groove when the mixing cylinder rotates within the support frame.

[0015] In one possible implementation, arc-shaped guide grooves are provided on both sides of the frame, and pulleys are provided on both sides of the bottom end of the support frame. When the support frame swings on the frame, the pulleys slide in the arc-shaped guide grooves.

[0016] The beneficial effects of this invention are as follows: The motor is started, and through the first transmission component, it transmits power to the mixing cylinder, driving the cylinder to rotate around its rotating shaft. Simultaneously, the motor transmits power to the support frame through the second transmission component, driving the support frame to swing around its swinging shaft. This causes the mixing cylinder to swing while rotating, achieving thorough mixing of the materials. The mixing cylinder both rotates around its own axis and swings with the support frame, generating a complex composite motion. Combined with the internal lifting liner, this effectively prevents material accumulation and stratification, avoiding potential production hazards in subsequent smelting processes. It solves the problem that most mixing devices only achieve physical accumulation rather than uniform mixing when mixing recycled materials and new raw materials. High-density raw materials and lightweight recycled materials are prone to stratification, leading to uneven composition and asynchronous melting after being added to the furnace, prolonging smelting time and increasing energy consumption.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] See Figures 1 to 5 This utility model provides a mixing device for proportioning recycled materials and new raw materials, comprising: a frame 3 hinged to a support frame 5 via a swing shaft 4; the support frame 5 rotatably connected to a mixing cylinder 7 via a rotating shaft 6; the rotating shaft 6 being located at the center of the top and bottom ends of the mixing cylinder 7; a first feed inlet 8 and a second feed inlet 9 being opened at the top end of the mixing cylinder 7; a discharge port 10 being opened at the bottom end of the mixing cylinder 7; a lifting liner 11 being provided on the inner wall of the mixing cylinder 7; a motor 12 being provided on the support frame 5; the motor 12 being connected to the mixing cylinder 7 via a first transmission assembly 1; the first transmission assembly 1 being used to transmit the power of the motor 12 to the mixing cylinder 7 to drive the mixing cylinder 7 to rotate around the rotating shaft 6; and the motor 12 being connected to the support frame 5 via a second transmission assembly 2; the second transmission assembly 2 being used to transmit the power of the motor 12 to the support frame 5 to drive the support frame 5 to swing around the swing shaft 4.

[0024] Preferably, the frame 3 has a tapered support structure, meaning the support legs of the frame 3 slope outwards from top to bottom. A swing shaft 4 is rotatably mounted below the top of the frame 3, and the support frame 5 is rotatably connected to the swing shaft 4, allowing the support frame 5 to swing stably on the frame 3. There are two rotating shafts 6: a first feed inlet 8, a second feed inlet 9, and a discharge outlet 10, both of which are positioned away from the rotating shafts 6. The motor 12 is connected to the support frame 5 via a first fixed base, providing support for the stable rotation of the motor 12. A fixed plate 26 is provided at the bottom of the frame 3 to increase its stability.

[0025] Specifically, firstly, recycled materials and new raw materials are fed into the mixing cylinder 7 through the first feed port 8 and the second feed port 9, and then the first and second feed ports 9 are closed. The motor 12 is then started, and the motor 12 transmits power to the mixing cylinder 7 through the first transmission assembly 1, driving the mixing cylinder 7 to rotate around the rotating shaft 6. Simultaneously, the motor 12 transmits power to the support frame 5 through the second transmission assembly 2, driving the support frame 5 to swing around the swing shaft 4. This causes the mixing cylinder 7 to swing while rotating, achieving thorough mixing of the materials. Finally, the discharge port 10 is opened to discharge the mixed material, and then the discharge port 10 is closed. By using a single motor 12 to simultaneously drive the first transmission assembly 1 and the second transmission assembly 2, power is saved while the mixing cylinder 7 rotates around its own axis and swings on the frame 3 with the support frame 5. This creates a complex compound motion in the mixing cylinder 7, which, in conjunction with the lifting liner 11 inside the mixing cylinder 7, effectively prevents material stratification and agglomeration within the mixing cylinder 7, significantly improving mixing uniformity and efficiency.

[0026] In some embodiments, the first transmission assembly 1 includes a drive gear 101, a transmission rod 102, a first driven gear 103, a second driven gear 104, and a gear ring 105. The drive gear 101 is mounted on the rotating shaft 6 of the motor 12. The two ends of the transmission rod 102 are respectively connected to the first driven gear 103 and the second driven gear 104. The transmission rod 102 is rotatably mounted on the fixed rotating cylinder 13 of the support frame 5. The first driven gear 103 meshes with the drive gear 101, and the second driven gear 104 meshes with the gear ring 105. The gear ring 105 is mounted on the outer wall of the mixing cylinder 7.

[0027] The motor 12 rotates, driving the drive gear 101 to rotate, and the first driven gear 103 rotates synchronously. The first driven gear 103 drives the second driven gear 104 to rotate synchronously through the transmission rod 102. The second driven gear 104 meshes with the gear ring 105, thereby driving the gear ring 105 and the mixing cylinder 7 to rotate around the rotating shaft 6.

[0028] In some embodiments, the second transmission assembly 2 includes a drive pulley 201, a driven pulley 202, a connecting rod 203, a slider 204, and a slide rail 205. The drive pulley 201 is mounted on the rotating shaft 6 of the motor 12. The drive pulley 201 is connected to the driven pulley 202 by a belt. A rotating rod 14 is provided inside the driven pulley 202. The rotating rod 14 is rotatably mounted on the fixed frame 15 of the support frame 5. One end of the rotating rod 14 is fixedly connected to one end of the connecting rod 203. The other end of the connecting rod 203 is hinged to the slider 204. The slider 204 is mounted on the slide rail 205, and the slide rail 205 is mounted on the frame 3.

[0029] The motor 12 rotates, driving the drive pulley 201 to rotate. The drive pulley 201 drives the driven pulley 202 to rotate via a belt. The rotating rod 14 inside the driven pulley 202 rotates on the fixed frame 15. The rotating rod 14 drives the connecting rod 203 to move circumferentially. The connecting rod 203 pushes the slider 204 to move back and forth on the slide rail 205, forming a crank-rocker structure. Since the guide rail is fixed to the frame 3, the support frame 5 swings back and forth on the frame 3 around the swing axis 4. The fixed frame 15 is connected to the support frame 5 through a second fixed seat.

[0030] It should be noted that the crank-rocker structure formed by the rotating rod 14 driving the connecting rod 203 to move circumferentially and the slider 204 to move back and forth on the slide rail 205 is a mechanical structure known to those skilled in the art, and its working principle and motion mode are well known, so it will not be described in detail here.

[0031] In some embodiments, a rotating rod 14 is provided with a rotating wheel 16 at one end of the fixed frame 15, and a placement groove 17 is provided in the rotating wheel 16, with the connecting rod 203 located at least partially in the placement groove 17.

[0032] When the rotating rod 14 rotates, it drives the rotating wheel 16 to rotate synchronously. The placement groove 17 inside the rotating wheel 16 drives one end of the connecting rod 203 to make a circular motion, so that the other end of the connecting rod 203 pushes the slider 204 to move on the slide rail 205. The placement groove 17 provides a stable and reliable hinge point for the connecting rod 203. The placement groove 17 restricts the movement trajectory of one end of the connecting rod 203, so that it can smoothly follow the rotating wheel 16 to make a circular motion, making the rotational power of the rotating rod 14 more stable and continuously transmitted to the connecting rod 203, reducing the impact generated during the movement process, and ensuring the smoothness of the oscillating action of the mixing cylinder 7.

[0033] In some embodiments, there are multiple sets of lifting liners 11, which are arranged in a spiral and uniformly disposed on the inner wall of the mixing cylinder 7.

[0034] As the mixing drum 7 rotates, the lifting liners 11 continuously scoop up the material at the bottom of the mixing drum 7 and lift it to a certain height. Then, as the mixing drum 7 reciprocates on the frame 3, the material detaches from the lifting liners 11 under the action of gravity. This process repeats continuously, causing the material to tumble and move axially within the drum, achieving efficient cyclic mixing, overcoming the problem of dead zones in the center, and further improving the mixing effect of the material.

[0035] In some embodiments, a plurality of clearance openings 18 are uniformly provided on the lifting liner 11, and the clearance openings 18 are used to prevent material from clogging on the lifting liner 11.

[0036] When the mixing cylinder 7 rotates, the clearance opening 18 on the lifting liner 11 prevents material from clogging the lifting liner 11, ensuring that the material can smoothly detach from the lifting liner 11 through the clearance opening 18 after being lifted to a certain height. The clearance opening 18 provides a falling channel for the material, ensuring that all lifted material can be thrown down smoothly.

[0037] In some embodiments, the free ends of the two rotating shafts 6 at the top and bottom of the mixing cylinder 7 are connected to the support frame 5 via bearing seats 19. When the mixing cylinder 7 rotates around the rotating shafts 6, the rotating shafts 6 at the top and bottom of the mixing cylinder 7 rotate smoothly within the bearing seats 19, supporting the stable rotation of the mixing cylinder 7.

[0038] In some embodiments, a reinforcing ring 20 is provided on the outer wall of the mixing cylinder 7, and the reinforcing ring 20 is positioned above the toothed ring 105. A limiting frame 21 is provided on the support frame 5, and a roller 22 is rotatably provided on the limiting frame 21, with the roller 22 abutting against the reinforcing ring 20.

[0039] When the mixing cylinder 7 rotates, the reinforcing ring 20 rotates synchronously with the cylinder body. The rollers 22 on the limiting frame 21 abut against the reinforcing ring 20 and roll, providing auxiliary support and limiting for the mixing cylinder 7. This provides additional radial support for the mixing cylinder 7, preventing deformation due to material imbalance or long-term use. The contact between the rollers 22 and the reinforcing ring 20 transforms sliding friction into rolling friction, reducing power loss and simultaneously providing auxiliary positioning for the mixing cylinder 7.

[0040] In some embodiments, a limiting ring groove 23 is provided on the reinforcing ring 20. The limiting ring groove 23 is used to accommodate the roller 22. When the mixing cylinder 7 rotates in the support frame 5, the roller 22 rotates in the limiting ring groove 23.

[0041] When the mixing cylinder 7 rotates within the support frame 5, the roller 22 rolls within the limiting ring groove 23 of the reinforcing ring 20, restricting the axial movement of the mixing cylinder 7 and ensuring smooth rotation. This prevents axial movement of the mixing cylinder 7 during rotation, ensuring that the mixing cylinder 7 always remains in the correct axial working position, thereby guaranteeing the stability of the meshing between the gear ring 105 and the second driven gear 104.

[0042] In some embodiments, arc-shaped guide grooves 24 are provided on both sides of the frame 3, and pulleys 25 are provided on both sides of the bottom end of the support frame 5. When the support frame 5 swings on the frame 3, the pulleys 25 slide in the arc-shaped guide grooves 24.

[0043] Support plates 27 are provided on both sides of the frame 3. Arc-shaped guide grooves 24 are provided on the support plates 27. When the support frame 5 swings around the swing axis 4, the pulleys 25 on both sides of the bottom of the support frame 5 slide within the arc-shaped guide grooves 24 on the support plates 27, guiding the support frame 5 to swing smoothly along a fixed trajectory. This provides precise guidance and stable support for the swing of the support frame 5. The arc-shaped guide grooves 24 ensure that the swing trajectory of the mixing cylinder 7 is concentric with the axis of the swing axis 4, making the swinging motion of the mixing cylinder 7 smooth. Simultaneously, the cooperation between the pulleys 25 and the guide grooves transforms the pure swing motion of the support frame 5 into a combination of swinging and rolling motion, reducing the frictional resistance and wear between the support frame 5 and the frame 3.

[0044] It should be noted that the material in the mixing cylinder 7 mentioned above is a mixture of recycled material and new raw materials.

[0045] Work process First, recycled material and new raw material are added into the mixing cylinder 7 through the first feed port 8 and the second feed port 9 at the top of the mixing cylinder 7, respectively. Then, the motor 12 is started, and the rotating shaft 6 of the motor 12 drives the drive gear 101 to rotate. The first driven gear 103 rotates synchronously, and drives the second driven gear 104 to rotate synchronously through the transmission rod 102. The gear ring 105 is subjected to force and rotates smoothly in the bearing seat 19 around the rotating shaft 6 at the center of its top and bottom ends.

[0046] Simultaneously, the rotating shaft 6 of the motor 12 drives the drive pulley 201 to rotate, and through belt transmission, the driven pulley 202 and its internal rotating rod 14 rotate. One end of the rotating rod 14, which passes through the fixed frame 15, drives the rotating wheel 16 to rotate. The placement groove 17 inside the rotating wheel 16 drives the connecting rod 203 to make a planar circumferential movement. The other end of the connecting rod 203 then pushes the slider 204 to reciprocate on the slide rail 205 on the support plate 27, thereby driving the entire support frame 5 to swing around the swing shaft 4 hinged to its frame 3.

[0047] When the support frame 5 swings, the pulleys 25 on both sides of the bottom end of the support frame 5 slide in the arc-shaped guide grooves 24 on the support plates 27 on both sides of the frame 3, while the limiting frame 21 and its rollers 22 set on the support frame 5 are always embedded in the limiting ring grooves 23 of the reinforcing ring 20 of the mixing cylinder 7 and roll, providing both auxiliary support and axial limiting for the mixing cylinder 7.

[0048] During this process, multiple sets of lifting liners 11 arranged in a spiral on the inner wall of the mixing cylinder 7 rotate with the cylinder body, lifting the material at the bottom of the mixing cylinder 7 to a high place and then scattering it. The clearance openings 18 on the lifting liners 11 effectively prevent material blockage and ensure the mixing effect.

[0049] In summary, driven by a single power source, the mixing cylinder 7 simultaneously rotates around its own axis and swings with the support frame 5, forming a complex compound motion that allows the materials inside the mixing cylinder 7 to be fully mixed. After being mixed evenly, the mixture is finally discharged from the discharge port 10 at the bottom of the mixing cylinder 7.
