[0002] The production equipment of traditional powder or granular refractory materials has a relatively simple structure and is generally divided into three steps: mixing and batching, metering and distributing, and distributing and packaging.

[0003] Refractory plastics are generally made by mixing a variety of materials in the form of tiny particles or dust. The quality of the product depends not only on the composition of the materials, but also on whether the mixing of the components is uniform. The traditional mixing device is a simple spiral mixer, but since powder solid particles do not have the function of self-diffusion under mixing operations like liquid materials, it is difficult for general equipment to ensure that materials of this nature can be mixed evenly, especially when the specific gravity and particle size of different component materials are different, making the quality of the entire operation even more difficult to guarantee.

[0004] The weighing equipment of traditional powder or granular refractory materials is also very simple in structure. It needs to be added manually or by a feeder, and the feed port needs to be opened and closed frequently, which makes it impossible to perform automatic continuous operation. During the adding process, the amount of dust generated by the batching barrel during the mixing process not only causes serious material loss, but also causes inaccurate material ratio after batching, and pollutes the working environment, making it difficult to ensure the health and labor safety of workers.

[0030] The feed port 101 of the vacuum pump is connected with the discharge port 102 of the storage bin through a suction pipe, and switch valves are provided on the suction pipe and the discharge pipe. The discharge port 102 of the vacuum pump is connected with the feed port 101 through the discharge pipe.

There is no need for the operator to frequently open the feed port 101 to add materials, and the operation is more convenient and efficient.

[0031] The method of using the present invention: First of all, it should be made clear that the batching device involved in the present invention is mainly used for stirring, mixing and batching operations of various types of powders and granular materials. The present invention takes the batching of refractory plastics as an example to explain its method of use in detail. When it is necessary to batch refractory plastics, first start the output rod of the telescopic push rod 500 to extend, and by starting the output rod of the telescopic push rod 500 to extend, push the sealing door 600 to move to seal the discharge port 102 to prevent the stirring mechanism in the batching barrel 100 from discharging materials through the discharge port 102 during the stirring process, and then connect one end of a plurality of discharge pipes to the discharge port 102 of the corresponding storage bin respectively, open the bin door of the storage bin, and then connect the other end of the discharge pipe to the corresponding feed port 101 is connected, and then the switch valve on the discharge pipe is started and the vacuum pump is started to draw negative pressure into the suction pipe. At this time, the material in the storage bin will be automatically guided and pressed into the discharge pipe under the action of atmospheric pressure, and flow out to the feed port 101 through the discharge pipe, and finally enter the batching barrel 100, and then the output shaft of the motor is started to rotate. By starting the output shaft of the motor, the output shaft of the reducer and the stirring shaft 210 at its end are driven to rotate. The rotation of the stirring shaft 210 can drive the horizontal stirring blade 220 on its outer side to rotate, and at the same time drive the scraper 250 to rotate together, so as to scrape off the material adhering to the scraper 250, and can also drive the first bevel gear 231 to rotate together, and the first bevel gear 231 can be driven to rotate together. The rotation of the wheel 231 can drive the second bevel gear 232 to rotate together. In addition, due to the fixing effect of the fixing seat 234 on the outer ring of the bearing and the sleeve effect of the inner ring of the bearing and the fixing rod 233, the rotation of the second bevel gear 232 can drive the axial stirring blades 240 thereon to roll and stir the materials in the batching barrel 100 in the vertical direction. The rotating stirring shaft 210 drives the transverse stirring blades 220 to realize the transverse stirring and mixing operation of the materials in the batching barrel 100, which greatly improves the mixing efficiency of the materials in the batching barrel 100, and the batching effect is better and more efficient. After the batching is completed, the output rod of the telescopic push rod 500 is started to retract, and the sealing door 600 is moved outward when the output rod of the telescopic push rod 500 is started to retract. The discharge port 102 is opened, and the material after mixing and batching is discharged into the discharge hopper 400 through the discharge port 102, and finally falls through the discharge hopper 400 to be collected by the collecting bucket placed below it, so as to realize fast and efficient batching and discharging operations. The present invention can not only realize the automatic feeding operation of the material in the batching barrel 100 through multiple feed ports 101, but also can realize fast and efficient mixing operation of multiple materials in the batching barrel through the efficient mixing mechanism, without the need for the operator to frequently open and close the feed port 101 to add materials one by one during the batching process, so the batching effect is better, and the material dust is avoided in the process of frequently opening the feed port 101 to add materials, thereby improving the accuracy of the batching, reducing the unnecessary loss of materials, and achieving higher batching efficiency.The operation is more convenient and labor-saving.
