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 stirred first, and then the binders are added for stirring to ensure that the raw materials for iron ditch casting are qualified.

Two symmetrically arranged lower stirring blades are fixedly connected to the lower stirring rod. The lower stirring rod is arranged close to the bottom surface of the cylinder. The upper stirring rod and the lower stirring rod are separated by a certain distance and intersect at an angle.

[0004] When the powder mixer in the related technology is used to mix the iron ditch castable, the material is in the form of fine dry powder, making it difficult to effectively and quickly mix the various raw materials during the mixing process. When adding the binder, the binder is poured directly on the raw material, causing the raw material dry powder on the top to easily clump and deteriorate, making it difficult to mix the castable evenly. Summary of the invention

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 6As shown, an iron channel castable mixing machine of the present invention comprises a shell 1 and a stirring assembly 2, a material turning assembly 3 and a spraying assembly 4 arranged in the shell 1.

[0030] The stirring assembly 2 includes a spiral piece 21 and a mounting shaft 22. The mounting shaft 22 is coaxially arranged with the shell 1. The spiral piece 21 is coaxially fixedly arranged at the lower end of the mounting shaft 22. The 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 on 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 axis. The material spreading box 32 is arranged on the rotating frame 31 along the radial direction of the mounting shaft 22. The material spreading box 32 is open at one end close to the mounting shaft 22. The bottom is hollowed out, and the spray assembly 4 is arranged on the rotating frame 31, which 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 independently controls the rotation. In the first state, the driving source 331 drives the rotating plate 33 to rotate in a direction away from the mounting shaft 22. At this time, the rotating plate 33 is in a divergent state, stirring the material in the shell 1. In the second state, the driving source 331 drives the rotating plate 33 to rotate in a direction close to the mounting shaft 22. At this time, multiple rotating plates 33 are overlapped end to end to form a closed cylinder, and the cylinder is tangent to the spiral sheet 21. The mounting shaft 22 and the rotating frame 31 are respectively externally connected with an independent driving assembly, and one driving assembly is used to control the mounting shaft 22. Rotation, a driving component is used to control the rotation of the rotating frame 31, and the two driving components have different rotation speeds to realize 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 shell 1 can be turned up and transported to the material scattering box 32, and scattered to the top of the material through the hollow at the bottom of the material scattering box 32. In this process, water or other liquid binders are added to the shell 1 through the spray component 4, so that after the material scattering box 32 scatters a layer of material, the spray component 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 iron ditch castable.

[0031] like Figures 2 to 5The cam 312 is a substantially parallelogram of the cam 314, with the cam 314 being arranged on a substantially parallelogram surface to enable the cam 312 to rotate relative to the cam 314 when the cam 314 is in a rotational relationship.

[0032] like Figures 2 to 6 As shown, a notch 333 for accommodating the material scattering box 32 is provided on one side of the rotating plate 33 close to the hinge column 332, and the side wall of the notch 333 close to the hinge column 332 abuts against the material scattering box 32, and a sliding plate 34 is provided between the other end of the notch 333 and the material scattering box 32, and 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 scattering box 32, and the other end of the sliding plate 34 slides in the rotating plate 33, and a roller is provided on the end surface of the sliding plate 34 abutting against the material scattering box 32, which can reduce the friction force when the sliding plate 34 and the material scattering box 32 move relative to each other.

[0033] like Figures 1 to 5 As shown, the material scattering box 32 is arranged on the side 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 plate 33 is overlapped and closed to form a cylindrical shape. At this time, the open end of the material scattering box 32 is located inside the cylinder formed by the closing of the rotating plate 33 in the top view. At this time, through the rotation of the spiral sheet 21, the material at the bottom of the shell 1 can be transported to the upper end of the cylinder formed by the closing of the rotating plate 33, and enter the material scattering box 32, and then the hollow part at the bottom of the material scattering box 32 is scattered to the surface of the material. The bottom of the material scattering box 32 is tilted downward from the opening end to the other end, so that the material in the material scattering box 32 can be evenly distributed from the opening end to the other end.

[0034] like Figures 1 to 6As shown, the spray 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 shell 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 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. The lower side of the horizontal rod 42 is arranged along its length direction. There are multiple nozzles 43, and connecting pipes are 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 connecting pipe and be evenly sprayed out from the nozzle 43. When the rotating plate 33 is in the second state, the nozzle 43 is located on the outside of the cylinder formed by the closing of the rotating plate 33, so as to avoid the binder being directly sprayed onto the material inside the cylinder. Instead, after the scattering box 32 scatters a layer of material into the shell 1, the nozzle 43 sprays a layer of liquid binder on the material, so as to avoid a large amount of binder being directly put into the material to cause problems such as material agglomeration.

[0035] The working principle of the present invention is as follows: when stirring the castable, raw materials are added into the shell 1 through the feed port, the driving source 331 drives the rotating plate 33 to rotate in a direction away from the mounting shaft 22, so that the rotating plate 33 is in a divergent state, the driving component is started to control the mounting shaft 22 and the rotating frame 31 to rotate, and the spiral piece 21 on the mounting shaft 22 and the rotating plate 33 on the rotating frame 31 are driven to rotate at a differential speed, so as to stir the material in the shell 1 so that the material is stirred evenly. After the material is fully stirred, the driving source 331 is started to make the rotating plate 33 rotate in a divergent state. The rotating plates 33 rotate to the second state, at which time the rotating plates 33 are connected end to end to form a closed cylinder. During this process, the spiral blades 21 transport the material at the bottom of the shell 1 upward to the scattering box 32, which is scattered into the shell 1 by the rotating scattering box 32. At the same time, the multiple nozzles 43 arranged on the horizontal rod 42 evenly spray a layer of liquid binder on the material scattered from the scattering box 32 until the material and the binder are evenly mixed, and then the qualified material is discharged from the discharge port at the lower end of the shell 1. At the same time, the spiral blades 21 are reversed to accelerate the discharge of the material in the shell 1.

[0036] The present invention also provides a mixing process using the above-mentioned iron channel castable mixing machine, which specifically includes the following steps: S1: According to the designed formula, the required raw materials are prepared, and the proportioned raw materials are added into the shell 1 through the feed inlet for stirring; S2: In the initial state, the rotating plate 33 is in the first state, in which 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, which can drive the rotating plate 33 and the spiral sheet 21 to stir the material in the housing 1 so that the material is stirred evenly. S3: Start the driving source 331 to rotate the multiple 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 the material at the bottom of the shell 1 can be transported upward to the material spreading box 32 through the rotation of the spiral sheet 21, and then scattered from the material spreading box 32 into the shell 1; S4: adding water or other liquid binder into the housing 1 through the spraying component 4, so that after the material spreading box 32 spreads a layer of material, the spraying component 4 can spray a layer of liquid binder until the material is evenly stirred; S5: Discharge the qualified materials from the discharge port at the lower end of the shell 1.
