Description

Technical Field

[0001] The utility model belongs to the technical field of port equipment, in particular to a vertical ore sand mixer. Background Art

[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. Its characteristics are that there are 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 the same variety from different origins 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 on 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

[0012] 1.

The bracket 1 includes a support frame 101, a maintenance platform 102 and an escalator 103. The support frame includes four support legs and four support beams. The maintenance platform is welded to the top of the support frame. The bottom of the mixer body 2 is fixed to the support beam of the support frame, and the maintenance platform is arranged around the upper part of the barrel 2; the top of the escalator is welded to the maintenance platform, and a fence 104 is welded around the maintenance platform 102.

[0024] The main body of the mixer includes a barrel 2, a feed trough 3, a reduction motor 4, a blade shaft 5, an upper support kit 6, a seated self-aligning bearing 7 and a mounting frame 8.

[0025] The upper end and bottom of the barrel body 2 are respectively provided with an upper cover 201 and a lower cover 202, the upper cover is provided with a feeding port, the feeding trough 3 is welded at the feeding port of the upper cover, and the lower cover is provided with a discharging port; a blade shaft 5 is provided in the barrel body 2, the upper end of the blade shaft is connected to the reduction motor 4 through an upper support kit 6, the upper support kit 6 is fixed at the center of the mounting frame 8, and the mounting frame 8 is welded across the upper part of the barrel body; the upper support kit 6 is composed of a bearing seat, a thrust spherical roller bearing and a skeleton oil seal. The lower end of the blade shaft is connected to a seated spherical bearing 7, and the seated spherical bearing is embedded in the center of the barrel body lower cover 202.

[0026] like Figure 3-Figure 5As shown, the blade shaft 5 includes a shaft 501, a large blade 502, a small blade 503 and a bottom blade 504. The large blade 502 is processed and welded by a long vertical steel plate and three curved horizontal steel plates, and a total of 4 blades are provided, which are welded on the shaft 501 at a 90° distribution; the small blade 503 is processed and welded by a short vertical steel plate and two curved horizontal steel plates, and a total of 4 blades are provided, which are welded on the shaft 501 at a 45° offset from the large blade 502; the bottom blade 504 is four long strip steel plates, which are vertically welded at the lower end of the shaft 501 at a 90° distribution.

[0027] Port bulk ore sand mixing process Figure 6 As shown, the mixed ore sand is loaded into different storage hoppers by the loader, flows to the belt scale below through the discharge port, and falls on the flat belt conveyor after being weighed according to the mixing ratio provided by the user. 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 mixer by the flat belt conveyor in a multi-layer superimposed straight line. Multiple ore sands enter through the inlet, and during the falling process, they are cut, separated or collided by the rotating multi-layer horizontal blades with curved surfaces, multiple vertical blades with cut angles, and the flat blades at the bottom, which greatly changes the movement trajectory of the ore sand, forcing this part of the ore sand to disperse in different directions and mix with the subsequent falling ore sand. This process is repeated many times until the ore sand falls from the discharge port, thereby improving the mixing effect of the ore sand.

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.
