Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-stage ore screening device for the above problems, which solves the problem that after the ore is broken, it is mostly irregular in shape, and the ore is easily stuck on the screen mesh due to the sharp corners on the surface of the ore. Mesh blockage affects production work; and the technical problem that the existing screening device cannot perform multi-stage screening of large and small ores at one time

Embodiment Construction

[0036] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0037] Such as figure 1 with figure 2As shown, a multi-stage ore screening device, the main box 1, the first screener 2, the second screener 3, the discharge frame 4, the first box 5 and the second box 6; the main box The body 1 is in the shape of a square cylinder with upper and lower openings, and its upper part is an upward trumpet-shaped material inlet 11. The two opposite side walls are respectively arranged at the first outlet 12 and the second outlet 13. The first outlet 12 is located higher than the second outlet 13. ; The first sieve 2 is fixed in the main box 1 and is located at the top of the main box 1, it is inclined, and its lower end is towards the first outlet 12; the second sieve 3 is fixed in the main box Inside and located at the lower part of the main box 1, it is located directly below the first sieve 2; it is inclined, an...

Abstract

The invention discloses a multi-level ore screening device, and belongs to ore mining and machining devices. The multi-level ore screening device comprises a main box body which is in the shape of a square barrel with upper and lower openings, an upward horn-shaped feed inlet is formed in the upper portion of the main box body, and a first outlet and a second outlet are formed in two opposite sidewalls correspondingly. The multi-level ore screening device further comprises a first screening device, a second screening device and a discharging frame, wherein the first screening device is fixedin the main box body and located on the upper portion of the main box body, and the lower end of the first screening device faces the first outlet; the second screening device is fixed in the main boxbody and located on the lower portion of the main box body, the second screening device is located under the first screening device, and the lower end of the second screening device faces the secondoutlet; and the discharging frame is located under the main box body and comprises a support and three discharge outlets which are arranged side by side. The multi-level ore screening device solves the technical problems that ore is likely to get stuck in screening holes to block the screening holes and production work is affected due to the fact that crushed ore is mostly in irregular shapes andpointed corners are located on the surface of ore, and existing screening devices cannot carry out one-time multi-level screening on large and small ore.

Description

technical field [0001] The invention relates to an ore mining and processing device, in particular to a multi-stage ore screening device. Background technique [0002] In the mining and quarrying industry, in many cases it is necessary to separate the crushed ore into different sized stones. In most cases, separation or screening is performed by supplying undivided ore to a vibrating screen having screen decks with mesh openings to allow ore smaller than the mesh openings to pass through. For larger ore, the sieve plate needs to be set in an inclined shape, and the ore slides from the upper surface of the sieve plate to one side. After the ore is crushed, it is mostly irregular in shape and has sharp corners on the surface of the ore. The ore is easy to get stuck on the mesh and cause the blockage of the mesh, which affects the production work. Now there is a screening device for multi-stage screening of the ore. The primary screening is carried out first, and then the sec...
