Technical Field

[0001] The present invention relates to the field of mixing technology, and particularly relates to a mixer for tapping mix and a mixing process thereof. Background Art

[0002] The mixing of tapping mix means mixing various raw materials in a certain proportion and then carrying out mixing through a specific process to prepare a tapping mix that meets the requirements. First, all raw materials need to be prepared, including aggregates, powders, binders, etc. The quality and proportion of these raw materials will directly affect the performance of the final product. Generally, the dry materials are first stirred, and then the binder and others are added for stirring to ensure that the raw materials for tapping are qualified.

[0003] A Chinese patent application document with the publication number CN105771737A discloses a powder mixer, which includes a cylinder body, a stirring shaft, and a transmission device.

[0036] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] As Figures 1 to 6 shown, a mixer for a trough casting material of the present invention includes a housing 1 and a stirring assembly 2, a material turning assembly 3, and a spraying assembly 4 provided in the housing 1.

[0038] The stirring assembly 2 includes a spiral blade 21 and a mounting shaft 22. The mounting shaft 22 is coaxially arranged with the housing 1. The spiral blade 21 is coaxially and fixedly arranged at the lower end of the mounting shaft 22. The material turning assembly 3 includes a rotating frame 31, a material spreading box 32, a rotating plate 33, and a driving source 331. The rotating frame 31 is rotatably sleeved on the upper end of the mounting shaft 22. At least two rotating plates 33 are hinged to the rotating frame 31 at equal intervals around the circumference of the mounting shaft 22. The driving source 331 is preferably a motor. The driving source 331 is arranged on the rotating frame 31. The driving source 331 is used to drive the rotating plate 33 to rotate around the hinge shaft. The material spreading box 32 is arranged on the rotating frame 31 along the radial direction of the mounting shaft 22. One end of the material spreading box 32 close to the mounting shaft 22 is open, and the bottom is hollowed out. The spraying assembly 4 is arranged on the rotating frame 31 and is used to spray the material when the rotating frame 31 rotates. The mounting shaft 22 and the rotating frame 31 are externally connected with a driving assembly that controls rotation independently. In the first state, the driving source 331 drives the rotating plate 33 to rotate away from the mounting shaft 22. At this time, the rotating plates 33 are in a divergent state to stir the material in the housing 1. In the second state, the driving source 331 drives the rotating plate 33 to rotate towards the mounting shaft 22. At this time, a plurality of rotating plates 33 are lapped end to end to form a closed cylinder, and the cylinder is tangent to the spiral blade 21. The mounting shaft 22 and the rotating frame 31 are respectively externally connected with an independent driving assembly. One driving assembly is used to control the rotation of the mounting shaft 22, and one driving assembly is used to control the rotation of the rotating frame 31. Different rotation speeds of the two driving assemblies realize the differential rotation of the mounting shaft 22 and the rotating frame 31. Through the rotation of the spiral blade 21, the material at the bottom of the housing 1 is turned up and conveyed into the material spreading box 32, and is scattered to the top of the material through the hollowed-out bottom of the material spreading box 32. During this process, water or other liquid binders are added into the housing 1 through the spraying assembly 4, so that after the material spreading box 32 scatters a layer of material, the spraying assembly 4 can spray a layer of liquid binder, which helps to mix the material and the liquid binder evenly and improve the mixing effect of the trough casting material.

[0039] As Figures 2 to 5As shown in the figure, the rotating frame 31 includes a plurality of support rods 311 and a sleeve 312. The sleeve 312 is rotatably sleeved on the mounting shaft 22. A limiting block is provided on the mounting shaft 22 so that the sleeve 312 can only rotate at a preset height. The plurality of support rods 311 are arranged at equal intervals in the circumferential direction of the sleeve 312. Each support rod 311 is arranged along the radial direction of the sleeve 312. The support rods 311 are arranged in one-to-one correspondence with the rotating plates 33. An articulated column 332 is provided at the upper end of one side of the rotating plate 33. The rotating plate 33 is hinged to the support rod 311 through the articulated column 332. The rotating plate 33 can rotate around the axis of the articulated column 332. An arc-shaped edge is provided on the other side of the rotating plate 33. When the plurality of rotating plates 33 are lapped end to end, the arc-shaped edge of the rotating plate 33 can abut against the articulated column 332 on another adjacent rotating plate 33 to form a closed cylinder.

[0040] As Figures 2 to 6 shown in the figure, a notch 333 for accommodating the material spreading box 32 is formed on one side of the rotating plate 33 close to the articulated column 332. The side wall of the notch 333 close to the articulated column 332 abuts against the material spreading box 32. A sliding plate 34 is provided between the other end of the notch 333 and the material spreading box 32. The sliding plate 34 is adapted to the shape of the rotating plate 33. One end of the sliding plate 34 abuts against the material spreading box 32. The other end of the sliding plate 34 slides within the rotating plate 33. Rollers are provided on the end face of the sliding plate 34 that abuts against the material spreading box 32, which can reduce the friction when the sliding plate 34 and the material spreading box 32 move relative to each other.

[0041] As Figures 1 to 5 shown in the figure, the material spreading box 32 is arranged on the side surface of the support rod 311 along the length direction of the support rod 311. When the rotating plate 33 is in the second state, the rotating plates 33 are lapped end to end to form a cylindrical shape. At this time, the open end of the material spreading box 32 is located inside the cylinder formed by the closing of the rotating plates 33 in the top view. At this time, through the rotation of the spiral blade 21, the material at the bottom of the housing 1 can be conveyed to the upper end of the cylinder formed by the closing of the rotating plates 33 and enter the material spreading box 32, and then be scattered onto the surface of the material through the hollow part at the bottom of the material spreading box 32. The bottom of the material spreading box 32 is inclined downward from the open end to the other end, so that the material in the material spreading box 32 can be evenly distributed from the open end to the other end.

[0042] As Figures 1 to 6As shown in the figure, the spraying assembly 4 includes a sleeve 41 and a plurality of horizontal rods 42. The sleeve 41 is sleeved on the sleeve 312, and the sleeve 41 rotates synchronously with the sleeve 312. The upper end of the sleeve 41 is externally connected to a device for adding a liquid binder into the housing 1. The plurality of horizontal rods 42 are arranged at equal intervals along the circumference of the sleeve 41 at the lower end of the sleeve 41. Each horizontal rod 42 is arranged along the radial direction of the sleeve 41. The number of the horizontal rods 42 is the same as that of the support rods 311, and the horizontal rods 42 and the support rods 311 are staggered in the top view. A plurality of spray nozzles 43 are arranged along the length direction on the lower side of the horizontal rod 42. A communication pipeline is arranged in the sleeve 41 and the horizontal rod 42, so that after the binder enters the sleeve 41, it can enter the horizontal rod 42 through the communication pipeline and be evenly sprayed out by the spray nozzles 43. When the rotating plate 33 is in the second state, the spray nozzles 43 are located outside the cylinder formed by the closing of the rotating plate 33, so as to prevent the binder from being directly sprayed onto the materials inside the cylinder. Instead, after the feeding box 32 sprinkles a layer of materials into the housing 1, the spray nozzles 43 spray a layer of liquid binder on the materials, so as to avoid problems such as material caking caused by a large amount of binder being directly put into the materials.

[0043] The working principle of the present invention is as follows: When stirring the castable, raw materials are added into the housing 1 through the feeding port. The rotating plate 33 is driven by the driving source 331 to rotate away from the mounting shaft 22, so that the rotating plate 33 is in a divergent state. The driving assembly is started to control the mounting shaft 22 and the rotating frame 31 to rotate, driving the spiral blades 21 on the mounting shaft 22 and the rotating plate 33 on the rotating frame 31 to rotate at a differential speed, stirring the materials in the housing 1 to make the materials evenly stirred. After the materials are fully stirred, the driving source 331 is started to make the plurality of rotating plates 33 rotate to the second state. At this time, the rotating plates 33 are connected end to end to form a closed cylinder. During this process, the spiral blades 21 convey the materials at the bottom of the housing 1 upwards into the feeding box 32, and the rotating feeding box 32 scatters them into the housing 1. At the same time, a plurality of spray nozzles 43 arranged on the horizontal rod 42 evenly spray a layer of liquid binder on the materials scattered by the feeding box 32 until the materials and the binder are evenly mixed. Then the qualified materials are discharged from the discharge port at the lower end of the housing 1. At the same time, the spiral blades 21 rotate in the reverse direction to accelerate the discharge of the materials in the housing 1.

[0044] The present invention also provides a mixing process using the above-mentioned tundish castable mixer, which specifically includes the following steps:

[0045] S1: According to the design formula, prepare the required raw materials, and add the proportioned raw materials into the housing 1 through the feeding port to prepare for stirring;

[0047] S3: Start the drive source 331 to rotate the plurality of rotating plates 33 to the second state. At this time, the rotating plates 33 are connected end to end to form a closed cylinder, and through the rotation of the spiral blade 21, the materials at the bottom of the housing 1 can be conveyed upward into the material spreading box 32, and then fall from the material spreading box 32 into the housing 1.

[0048] S4: Add water or other liquid binders into the housing 1 through the spraying component 4, so that after the material spreading box 32 spreads a layer of materials, the spraying component 4 can spray a layer of liquid binder until the materials are stirred evenly.

[0049] S5: Discharge the qualified materials from the discharge port at the lower end of the housing 1.
