Abstract
Description
Technical Field
[0001] The utility model relates to an ore sample mixing auxiliary device. Background Art
[0002] In mineral processing test research, the ore samples collected need to be crushed to a suitable particle size and then mixed. Traditional sample mixing methods include the ring cone method, the shifting cone method, and the rolling method, and each has formed relevant operating standards. Through standardized operations, the uniformity of the mixed samples can be effectively improved. In addition, with the continuous development of science and technology, a variety of automated sample mixing equipment has been launched, which realizes the mixing and reduction of samples on the basis of following the traditional disposal principles, and improves the sample processing efficiency.
[0003] Although the traditional sample mixing method does not require additional equipment, is simple to operate, and is widely used, it is greatly affected by human factors due to the different operating levels and behavioral habits of each person. The mixing effect of the final sample varies greatly when different people operate it, and a large amount of dust will be generated during the cone transfer process, which deteriorates the operating environment. Although the automated sample mixing equipment eliminates human errors, improves the sample mixing efficiency, and improves the working conditions, it generally has the disadvantages of being bulky, cumbersome to use, and incomplete cleaning leading to sample contamination. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a sample mixing auxiliary device using a cone transfer method, which is simple and practical, can improve the sample mixing effect and has the function of preventing dust diffusion.
[0005] The technical solution of the utility model is as follows:
[0006] A sample mixing auxiliary device for a cone transfer method comprises a hopper in a truncated cone shape with a feed outlet at the lower end, a bracket being fixedly connected to the outer wall of the hopper, and a flow guide tube whose axis coincides with the axis of the hopper is connected to the feed outlet; a plurality of hooks are also fixed to the outer wall of the hopper; the sample mixing auxiliary device also comprises a flexible dust cover whose upper end is connected to the hook and whose lower end is flush with the lower end of the bracket or exceeds the lower end of the bracket.
[0007] Preferably, the bracket includes three or four legs evenly distributed circumferentially; the legs include an outer sleeve whose upper end is fixed to the outer side wall of the hopper, and a telescopic rod is installed in the outer sleeve; a locking nut is installed between the outer sleeve and the telescopic rod.
[0008] Compared with the prior art, the utility model has the following beneficial effects.
[0009] First, the utility model can realize the standardized operation of sample mixing, reduce the problem of uneven distribution during manual cone transfer, reduce human errors, and improve the sample mixing effect. At the same time, the operation is simple, and only the sample needs to be added to the hopper, thereby improving work efficiency.
[0010] Second, the hopper discharge port of the utility model is connected with a guide pipe. Since the guide pipe is perpendicular to the work surface and the material flows for a distance in the guide pipe, the material can fall vertically to the top of the material pile and then spread evenly around. The drop point is centered and stable, thereby improving the sample mixing effect.
[0011] Third, the utility model provides a cylindrical flexible dust cover on the outside of the hopper, the upper end of the dust cover is hung on several hooks on the outside of the hopper, and the lower end is hung on the work surface to form a closed space. The dust generated during the material dropping process is sealed in the dust cover, which effectively improves the working environment.
[0012] Fourthly, in the optimized technical solution of the utility model, the legs are telescopically adjustable, and the hopper can be adjusted to a suitable height according to the number of samples during use, thereby increasing the adaptability to samples of different weights.

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0016] like Figure 1 As shown, the embodiment of the utility model comprises a hopper 3, a feeding port 5 is arranged at the lower end of the hopper, and a flow guide pipe 6 whose axis coincides with the axis of the hopper 3 is connected to the feeding port 5. A bracket 4 is fixedly connected to the outer wall of the hopper 3.
[0017] A hanging ring with a plurality of hooks 1 is also fixed on the outer wall of the hopper 3. The hanging ring is generally a circle of iron wire, which is fixed to the outer wall of the hopper 3 by spot welding, and the plurality of hooks 1 are welded to the iron wire evenly distributed in the circumferential direction.
[0018] This embodiment also includes a cylindrical flexible dust cover 2, the upper end of which is connected to the hook 1 and the lower end of which is flush with the lower end of the bracket 4 or exceeds the lower end of the bracket 4. The exceeding the lower end of the bracket 4 means that the flexible dust cover 2 has a length margin, and after the lower end of the bracket 4 is placed on the work platform, the lower end of the flexible dust cover 2 covers the work surface.
[0019] The support 4 includes three or four legs evenly distributed in the circumferential direction. Figure 1 Only two of them are shown. The legs include an outer sleeve whose upper end is welded to the outer side wall of the hopper 3, and a telescopic rod is installed in the outer sleeve. When in use, the lower end of the telescopic rod is used to contact the work surface. A locking nut 7 is installed between the outer sleeve and the telescopic rod. After the extension length of the telescopic rod is adjusted, the inner end of the locking nut 7 passing through the outer sleeve is pressed against the telescopic rod to lock the legs.
[0020] In actual preparation, the hopper 3 is a truncated cone with a larger upper area than a lower area, and the hopper wall thickness is preferably 1-2 mm, and the material is a smooth metal plate. The guide tube 6 is a stainless steel tube and the upper end is welded to the feed port 5. The flexible dust cover 2 is generally made of plastic film.
[0021] The following examples illustrate the use of the embodiments of the present invention.
[0022] When in use, place the sample mixing auxiliary device on a horizontal work surface, adjust the bracket 4, adjust the distance between the lower end of the flow guide tube 6 and the work surface according to the mixing amount, and make the flow guide tube 6 run perpendicular to the work surface. After adjustment, lock the legs of the bracket 4 through the locking nut 7.
[0023] After the sample to be mixed is added to the hopper 3, the sample is discharged in sequence through the discharge port 5 and the guide pipe 6. During the discharge process, a pressing block is used to press the lower end of the flexible dust cover 2 onto the work surface.
