[0002] As a bulk raw material, my country imports a huge amount of loose ore every year. It is the mainstay of loading and unloading business in major ports. It mainly comes from countries and regions rich in mineral resources such as Brazil, Australia, and Africa. It is characterized by many varieties, and the content of various effective elements in each variety is different. Due to different origins, even the same variety of ore sand contains different effective elements. In view of the above situation, in order to improve their own production efficiency or smelt products of different qualities, users have put forward the requirement of mixing ore sands of different varieties or different origins of the same variety in proportion. Therefore, in recent years, ore sand mixing business has been derived in the port area, and the demand is increasing. At present, the mixing operation is carried out: first, the materials are covered layer by layer by stackers and reclaimers in the material yard. This process only has requirements on the specific gravity of various materials within a certain amount range, but not on the mixing effect; second, there are strict requirements on the mixing specific gravity and mixing effect. This type of mixed goods now mostly use conventional material mixing equipment, such as stirring, auger, spiral, drum, etc. Compared with other conventional goods, mineral sand has characteristics such as high specific gravity and poor fluidity, resulting in problems such as uneven mixing and low efficiency, which cannot meet customer needs.

[0003] Therefore, designing a mineral sand mixer with uniform and high efficiency to mix high-quality mixed mineral products and provide customers with high-quality services is a problem we need to solve. Summary of the invention

[0023] Example 1

[0024] like Figures 1 to 3 As shown, this embodiment provides a multi-stage ore sand mixer, including a box body 1 with upper and lower openings, wherein the box body is provided with a primary diverter plate 2, a secondary bulk material mixing mechanism 3 and a tertiary bulk material mixing mechanism 4 in order from top to bottom. The box body 1 is welded from steel plates, the upper part is in a rectangular parallelepiped shape, the lower part is in a four-sided platform shape, the upper opening is a material inlet, and the lower part is a material outlet.

[0025] like Figure 4 As shown, the primary flow divider 2 is composed of 6 fan-shaped flow guide plates 201, and each fan-shaped flow guide plate is evenly spaced and welded to the front and rear inner walls of the box.

[0026] In the mixer, two groups of secondary bulk material mixing mechanisms 3 are arranged in parallel, and one group of tertiary bulk material mixing mechanisms 4 is arranged, and the tertiary bulk material mixing mechanism is located below the middle position of the two groups of secondary bulk material mixing mechanisms.

[0027] like Figure 5 As shown, each set of secondary bulk material mixing mechanism 3 includes a secondary reduction motor 301, a secondary drive roller 302 and a tooth plate 303; the secondary reduction motor is arranged outside the box, and its output shaft is connected to the secondary drive roller extending into the box, and a plurality of tooth plates are evenly arranged on the shaft of the secondary drive roller, and the tooth plates are T-shaped parabolic. The T-shaped parabolic tooth plates in the two sets of secondary bulk material mixing mechanism 3 are arranged crosswise, and the rotation directions are opposite.

[0028] like Figure 6 As shown, the three-stage bulk material mixing mechanism 4 includes a three-stage reduction motor 401, a three-stage drive roller 402 and a spiral blade 403; the three-stage reduction motor is arranged outside the box, and its output shaft is connected to the three-stage drive roller extending into the box, and the three-stage drive roller is provided with a spiral blade on its shaft. The spiral blade 403 includes a first spiral blade 403-1 and a second spiral blade 403-2, and the spiral directions of the two are opposite.

[0029] The operation mode of the multi-stage ore sand mixer described in this embodiment is:

[0030] The ore sands to be mixed are loaded into different storage hoppers by loaders, flow to the belt scale below through the discharge port, and after being weighed according to the mixing ratio provided by the user, the ore sands fall on the flat belt conveyor. Because multiple storage hoppers are arranged in a line along the direction of the flat belt conveyor, the different ore sands that fall are transported to the inlet of the multi-stage ore sand mixer described in this embodiment in a multi-layer superimposed straight line by the flat belt conveyor. Multiple ore sands enter the box body 1 through the inlet port. During the falling process, the ore sands are first dispersed and dropped to both sides through the first-level diverter plate 2, and then through two sets of counter-rotating second-level bulk material mixing mechanisms 2, the ore sands are cut and dispersed in the circumferential direction and transversely by T-shaped parabolic tooth plates, and the block ore sands can also be crushed; the ore sands continue to fall, and then through the third-level bulk material mixing mechanism 4, the ore sands are cross-mixed in three dimensions by spiral blades, and finally the mixed ore sands fall from the discharge port to the stacking belt conveyor for storage.

[0031] Finally, it should be noted that the above is only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred arrangement scheme, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
