Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, in particular to a spiral chute ore separator. Background Art

[0002] The spiral chute separator is a simple-to-use, energy-saving and efficient mineral separation equipment. It can separate different minerals according to their particle specific gravity. The water flows on the spiral chute surface and constantly changes its movement direction, thus generating centrifugal force on the cross section of the spiral chute. The centrifugal force causes the liquid particles in the upper water flow to flow toward the outer edge of the trough under the lateral resultant force. The water layer on the outer edge is thick and the flow rate is high, while the water layer on the inner layer is thin and the flow rate is low. Therefore, the light and heavy minerals are evenly arranged horizontally from the outer edge to the inner edge. The long-distance separation makes the mineral distribution as balanced as possible for mineral processing.

[0003] At present, most spiral chutes on the market are of one-piece type. Due to the different impact forces of materials from top to bottom, the spiral chute at the bottom is more susceptible to wear and damage. Since it is an integrated type, it needs to be replaced as a whole, which is more costly. Secondly, several diverter blocks are currently designed at the end of the spiral chute. The diverter blocks are fixed to the spiral chute by screws passing from bottom to top. The above method will first damage the spiral chute itself. Secondly, due to the different weights and contents of materials in different minerals, the size and number of the diverter blocks often need to be adjusted. Since they are installed on the spiral chute by screws, only one large category of minerals can be processed, resulting in poor applicability. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Reference Figure 1-4 A spiral chute ore separator includes a spiral chute 2, a feed port 1 and several diversion mechanisms, wherein the spiral chute 2 includes a top chute 24, a tail chute 21 and several spiral segments 23, the top chute 24, the spiral segment 23 and the tail chute 21 are spliced ​​together from top to bottom, and enclosed to form a spiral channel that satisfies the downward flow of materials, the upper and lower end faces of the spiral segment 23, the bottom end face of the top chute 24 and the top face of the tail chute 21 are all provided with outwardly protruding mounting plates 25, and a plurality of mounting holes 251 are evenly distributed on the mounting plate 25. The spiral chute 2 is designed to be multi-section splicing. When a section is damaged, it can be directly removed and replaced, which can greatly reduce the overall replacement cost. At the same time, the overall length of the spiral chute 2 can also be adjusted according to actual needs. In addition, it can also be removed for segmented transportation during transportation.

[0022] The mounting plates 25 arranged opposite to each other are fixed by a combination of screws and nuts (not shown) passing through the mounting holes 251 .

[0023] Furthermore, multiple diversion mechanisms are spaced apart at the tail of the tail chute 21. The diversion mechanism includes a diversion plate 3, a butterfly nut 5 and a support plate 6. The diversion plate 3 and the support plate 6 together form a "匚"-shaped space for clamping at the tail of the tail chute 21. A vertically upward threaded rod 4 is provided on the top of the support plate 6. The diversion plate 3 is provided with a through hole for the threaded rod 4 to pass through. The threaded rod 4 passes through the through hole and is threadedly connected to the butterfly nut 5. A clamping and fixed diversion mechanism is designed at the tail end of the tail chute 21. The number and spacing of the diversion mechanisms can be adjusted according to the weight and content of different types of ores, which can meet the ore separation and beneficiation operations of various types of ores. When adjusting, the butterfly nut 5 is unscrewed outward. At this time, the spacing between the diversion plate 3 and the support plate 6 becomes larger, and the position of the diversion mechanism can be adjusted left and right. After the position adjustment is completed, the butterfly nut 5 can be locked. No tools are required for adjustment, and the above fixing method will not cause damage to the tail chute 21.

[0024] Furthermore, the diverter plate 3 is attached to the upper wall of the tail end of the tail chute 21, and the front end of the diverter plate 3 is conical. The advantage of the conical shape is that it can prevent the ore from accumulating at the front end of the diverter plate 3 during ore separation.

[0025] Furthermore, the cross section of the support plate 6 is L-shaped, and the upper end surface of the transverse portion of the support plate 6 is provided with anti-slip grooves 61. The anti-slip grooves 61 can increase the friction between the diversion mechanism and the tail chute 21, thereby improving the fixing effect of the diversion mechanism.

[0026] Further, the tail chute 21 tail end surface is provided with scale 211 along the transverse direction, the scale 211 can facilitate the staff to know the distance after adjusting the shunt mechanism, to improve the subsequent shunt accuracy.

[0027] Further, the spiral segment 23, top chute 24 and tail chute 21 both sides are provided with the baffle 26 which is bent upwards, the feeding port 1 is arranged on the top chute 24 upper end opening, the baffle 26 can avoid the material from the spiral chute 2 in the process of centrifugal.

[0028] Further, the top chute 24, tail chute 21 and spiral segment 23 outer end surface is provided with the mounting column 22 with flange along the vertical direction, the bottom of the mounting column 22 on the tail chute 21 is further provided with a support base.

[0029] The above only for the preferred embodiment of the present application has been described, and not to limit the present application, any modification, equivalent replacement and improvement etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
