Description
Technical field
The utility model relates to a kind of mine mechanism technical field, especially relates to a kind of vortex sieve of ripple stainless steel mesh.
Background technology
Vortex sieve is a kind ofly with compass screen surface, to make cyclone cylinder and borrow centrifugal force to realize by the equipment of grain graininess classification.Be applicable to the classification of fine,
It is large that this classifying equipoment has production capacity; the gravity flow screen that classification efficiency advantages of higher is current; its sieve surface is inferior pyramidal net cylinder face; this kind of sieve; it is the segmentation for thin material; feed from the side; with the ore pulp motion compass screen surface of flowing through of spinning; fines sees through sieve aperture and discharges; coarse fodder is discharged through lower pyramid mouth, and the shortcoming of this vortex sieve is because screen cloth is arc slope, and the fine sand that many in ore pulp can open-work confuses coarse grain and emits through lower pyramid mouth; so wasted widely the treating capacity of ore pulp, this is the problem in vortex sieve operation.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, convenient operation, and long service life, can improve the vortex sieve of the ripple stainless steel mesh of screening efficiency.
The purpose of this utility model realizes by following technical proposals:
The vortex sieve of ripple stainless steel mesh of the present utility model, comprise cylindrical shape outer cylinder body, be arranged on the screen cloth in cylindrical shape outer cylinder body, be arranged on the mineral-feeding pipe on cylindrical shape outer cylinder body top, be arranged on base plate and the ore discharge pipe of cylindrical shape outer cylinder body bottom, it is characterized in that being also provided with annular hopper on described cylindrical shape outer cylinder body top, on the outer of described cannelure, be arranged with the through hole being communicated with mineral-feeding pipe, the first-class charging aperture that is arranged with of barrel above cylindrical shape outer cylinder body, in described cylindrical shape outer cylinder body, be provided with back taper supporting slat, in the inner side of back taper supporting slat, be provided with macropore expanded metals, and in the inner side of macropore expanded metals, be provided with back taper ripple stainless steel mesh.
Described charging aperture is triangle charging aperture, and the opening direction of its triangle charging aperture is the direction of opening in the same way.
Described back taper ripple stainless steel mesh mesh is 1/10 of macropore expanded metals mesh.
Semicircle or triangle that described ripple stainless steel mesh is convex-concave structure.
The utility model has the advantages that: when triangle discharge gate when discharge of ore pulp from feed pipe, cannelure and cylindrical shape outer cylinder body top, ore pulp is oblique in the motion of spinning of ripple stainless steel sift net surface, because ripple stainless steel mesh is the screen surface of convex-concave, the developed area of ripple screen cloth is greater than not developed area, the utility model is compared with the vortex sieve of existing technology, can improve screening efficiency more than 25%, energy-conservation is on year-on-year basis more than 25%, and long service life.
Accompanying drawing explanation
Fig. 1 is to be structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As Figure 1-Figure 2, the vortex sieve of ripple stainless steel mesh of the present utility model, comprise cylindrical shape outer cylinder body 3, be arranged on the screen cloth 4 in cylindrical shape outer cylinder body 3, be arranged on the mineral-feeding pipe 1 on cylindrical shape outer cylinder body 3 tops, be arranged on base plate 7 and the ore discharge pipe 8 of cylindrical shape outer cylinder body 3 bottoms, it is characterized in that being also provided with annular hopper 2 on described cylindrical shape outer cylinder body 3 tops, on the outer of described cannelure 2, be arranged with the through hole being communicated with mineral-feeding pipe 1, described cannelure 2 is the annular groove of " ㄈ " shape; The first-class charging aperture 9 that is arranged with of barrel above cylindrical shape outer cylinder body 3, in described cylindrical shape outer cylinder body 3, be provided with back taper supporting slat 6, in the inner side of back taper supporting slat 6, be provided with macropore expanded metals 5, and be provided with back taper ripple stainless steel mesh 4 in the inner side of macropore expanded metals 5.
Because the net wall of back taper ripple stainless steel mesh 4 is thinner, fragile, therefore, in the outside of back taper ripple stainless steel mesh 4, be provided with back taper supporting slat and macropore expanded metals, not only play supporting role, but also effectively improved the service life of back taper ripple stainless steel mesh.
Charging aperture 9 described in the utility model is triangle charging aperture, and the opening direction of its triangle charging aperture is the direction of opening in the same way.The triangle charging aperture of opening can make material enter in vortex sieve with tangential direction in the same way, improves screening efficiency.
Semicircle or triangle that ripple stainless steel mesh 4 described in the utility model is convex-concave structure.This ripple stainless steel mesh 4 has improved sieving area effectively, and described back taper ripple stainless steel mesh 4 mesh are 1/10 of macropore expanded metals 5 mesh simultaneously.The utility model is compared with the vortex sieve of existing technology, can improve screening efficiency more than 25%, and energy-conservation is on year-on-year basis more than 25%.
