A crushing and iron removal equipment in mullite production

Abstract

A crushing and iron removal device in mullite production belongs to the technical field of crushing equipment. It is designed to solve the problem that the existing primary crushing equipment has poor crushing effect and cannot meet the step of iron removal. The crushing component of the present invention comprises a crushing mechanism, a guide mechanism, a transmission component, a rotating rod and a driving mechanism arranged inside an outer box. The raw material enters the inside of the outer box through a feed port, and the driving mechanism drives the rotating rod to rotate. The rotating rod drives the first transmission plate, the second transmission plate, the third transmission plate and the fourth transmission plate to rotate. Since the diameters of the first transmission plate, the second transmission plate, the third transmission plate and the fourth transmission plate are gradually reduced, when the transmission component drives the crushing mechanism to crush through the guide mechanism, the swing range of the first crushing plate, the second crushing plate, the third crushing plate and the fourth crushing plate gradually becomes smaller, and the swing speed gradually increases. When the raw material passes from top to bottom, multi-stage crushing is achieved. Compared with the existing primary crushing equipment, the crushing effect is good.

Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to crushing and iron removal equipment in mullite production. Background Art

[0002] Mullite is an aluminum silicate mineral whose crystal structure belongs to the orthorhombic system. It is a spatial network structure composed of aluminum oxide octahedrons and silicon oxide tetrahedrons connected to each other. This structure gives mullite good stability and high hardness. The production of mullite is to crush and screen the raw materials of coal gangue, kaolin and potassium feldspar respectively, and then mix them through ball milling, dry granulation, and sinter them after drying.

[0003] During the production process, the raw materials need to undergo primary crushing before iron removal. If the crushing effect is not good, it will affect the iron removal effect. If the crushing effect is too good, such as using a ball mill and a roller mill, the efficiency and working time of subsequent iron removal will increase. The current equipment used for primary crushing has a poor crushing effect and cannot meet the needs of this step of crushing and iron removal. Summary of the invention

[0025] In order to solve the technical problem that the existing primary crushing equipment has poor crushing effect and cannot meet the iron removal step, such as Figure 1-Figure 10 As shown, the following preferred technical solutions are provided:

[0027] like Fig. 9 and Fig.10 As shown, the transmission assembly 5 is provided with two groups and is respectively arranged at the front and rear of the inner part of the outer box 1. The transmission assembly 5 includes a first transmission disc 51, a second transmission disc 52, a third transmission disc 53 and a fourth transmission disc 54 corresponding to the first crushing plate 31, the second crushing plate 32, the third crushing plate 33 and the fourth crushing plate 34 respectively.

When the first transmission plate 51, the second transmission plate 52, the third transmission plate 53 and the fourth transmission plate 54 rotate, the eccentric shaft 55 and the connecting rod 56 drive the guide block 43 to slide in the second slide groove 14, and then the guide shaft 42 drives the arc guide plate 41 to slide in an arc, so that the first crushing plate 31, the second crushing plate 32, the third crushing plate 33 and the fourth crushing plate 34 are swung and squeezed in an arc.

[0032] like Fig. 9 As shown, the driving mechanism 7 includes a motor 71 fixedly installed at the lower part of the outer box 1, and the driving mechanism 7 also includes a transmission rod 72 horizontally placed below the two groups of rotating rods 6.
