Description

Technical Field

[0001] The present invention relates to the technical field of refractory material production equipment, and particularly to a batching machine for refractory material production. Background Art

[0002] Refractory materials are applied to various fields of the national economy such as iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. They are essential basic materials to ensure the production operation and technological development of the above industries and play an irreplaceable important role in the development of high-temperature industrial production. In the production process of refractory materials, a batching machine is usually required to mix various batching materials. However, the current batching machine has a single stirring structure, poor mixing effect on the batching materials, and low efficiency.

[0003] Therefore, the Chinese patent with the publication number "CN216171865U" discloses a "batching machine for refractory material production". Its main structure includes a cylinder body. A connection box is slidably connected to the top of the cylinder body. A motor is fixedly installed on the inner wall of the top of the connection box. A vertical shaft is fixedly connected to the output shaft of the motor. The vertical shaft extends into the cylinder body and is fixedly installed with a plurality of stirring plates. A worm is fixedly sleeved on the outer side of the vertical shaft. Two worm wheels are rotatably installed in the connection box. The worm is meshed with the two worm wheels. A connecting shaft is fixedly welded to the front side of each of the two worm wheels. Two sliding plates are slidably connected in the connection box. This batching machine for refractory material production can stir and mix various batching materials through the vertical shaft and a plurality of stirring plates by driving the motor. At the same time, through the meshing transmission of the worm and the two worm wheels, and through the movable contact of the two connecting shafts with the corresponding sliding plates, as well as the elastic deformation of a plurality of springs, and in addition, through the common cooperation of two rotatably connected support rods, a plurality of stirring plates can reciprocate up and down to stir and mix various batching materials, with good mixing effect on various batching materials, high efficiency, and improved production efficiency.

[0004] Obviously, when the above-mentioned batching machine for refractory material production stirs and mixes materials, it uses the reciprocating up and down movement of the stirring plates to stir and mix various batching materials. However, the cylinder body will not produce a rotating effect, and some of the raw materials in the cylinder will be deposited directly below the stirring plates and cannot be contacted by the stirring plates. At this time, the raw materials in this area will not be effectively mixed, resulting in a reduction in its stirring and mixing efficiency. At the same time, the stirring plates in a single area can only make the raw materials around them be in a rapid stirring state. For the raw materials far away from their surroundings, it takes a certain amount of time. Therefore, its stirring efficiency is still low. Summary of the Invention

[0021] To achieve the effective stirring and mixing function of raw materials, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set up a rotary stirring and mixing mechanism 3, which internally has a stirring and mixing cylinder 39 with a hollow structure inside and capable of mixing and stirring the raw materials located inside it during rotation, a driving motor 35 fixedly installed at one end of the stirring and mixing cylinder 39 and capable of driving the stirring and mixing cylinder 39 to rotate, and a component mounting bracket 33 capable of making the driving motor 35 rotate around the crossbeam 2. First, make the material discharge channel 310 in the stirring and mixing cylinder 39 inclined upward, and then inject the raw materials to be mixed into the inside of the stirring and mixing chamber 311 through the second material discharge hole 53. Then close the second material discharge hole 53. When the stirring and mixing cylinder 39 is in a horizontal state, then start the driving motor 35, and the rotor 37 will drive the stirring and mixing cylinder 39 to rotate. At this time, the raw materials located inside the stirring and mixing cylinder 39 will produce a flipping effect under the action of their own gravity. The flipping will cause the raw materials to flow, and the multiple stirring rods 312 will generate resistance to the flowing raw materials, so that the raw materials are stirred and mixed during the flipping process, thereby achieving the effective stirring and mixing function of the raw materials. When the stirring is completed, make the stirring and mixing cylinder 39 in a positive vertical state, and then open the second material discharge hole 53. Under the action of its own gravity, the finished materials can be discharged outward.

Then, a negative pressure machine capable of controlling the gas flow direction is taken, and the gas circuit of the negative pressure machine and the gas flow channel 47 are connected by a pipeline. When the negative pressure machine is started, under the action of the gas suction force, the first piston body 49 will move upward.

The turning will cause the raw materials to flow, and the plurality of stirring rods 312 will generate resistance to the flowing raw materials, so that the raw materials are stirred and mixed during the turning process, and thus the effective stirring and mixing function of the raw materials is realized. When the stirring is completed, make the stirring and mixing cylinder 39 in a positive vertical state, and then open the second material discharge hole 53. Under the action of its own gravity, the finished materials can be discharged outward.
