Description
TECHNICAL FIELD
[0001] The utility model relates to mine equipment technical field, concretely is a kind of ore separation vibrating screen. BACKGROUND
[0002] In the current ore processing industry, vibrating screen as a commonly used mine machinery, its main function is to screen classification to ore, so as to facilitate subsequent processing. The working principle of vibrating screen is that ore jumps on the screen surface by vibration, so as to realize the relative movement of ore and screen hole, and achieve the purpose of screening.
[0003] However, the conventional vibrating screen in use, due to the size, shape and hardness of ore, often there is ore plugging screen hole. This plugging not only reduces the working efficiency of vibrating screen, but also seriously affects the screening quality. When the screen hole is blocked, the ore cannot pass through the screen surface normally, resulting in incomplete screening, and even may cause the shutdown of the entire screening system.
[0004] In the long running process, the plugging problem becomes more and more serious, resulting in increased energy consumption of vibrating screen and intensified screen wear, thereby shortening the service life of screen. In order to solve this problem, manual cleaning is usually required, which not only consumes a lot of manpower and time, but also reduces the production efficiency and increases the production cost. Therefore, how to effectively solve the problem of vibrating screen plugging, improve the working efficiency and screening quality of vibrating screen, has become a technical problem to be solved in the ore processing industry. UTILITY MODEL CONTENT
[0005] In view of the deficiencies of the prior art, the utility model provides an ore separation vibrating screen, which solves the problem of ore plugging screen hole of the existing vibrating screen during work.
[0006] To achieve the above purpose, the utility model is realized by the following technical scheme: an ore separation vibrating screen, comprising a screen frame, a screen assembly is arranged in the screen frame, a lower layer guide plate is arranged below the screen assembly, the screen assembly comprises a plurality of screen units arranged obliquely in sequence from the inlet to the outlet, and the discharge end of each screen unit is suspended above the inlet of the next screen unit.
[0007] Each screen unit comprises a screen frame, the inner side of the screen frame is hollow, and a continuous curved second reinforcing rib is arranged at the bottom of the hollow part along the ore flow direction; an inner screen frame is fixed in the hollow part of the screen frame, and a continuous curved first reinforcing rib is arranged in the inner screen frame along the ore flow direction, and a mesh hole is formed between the first reinforcing rib and the second reinforcing rib.
[0008] Preferably, the first reinforcing rib is located above the second reinforcing rib.
[0009] Preferably, the first reinforcing rib comprises a plurality of first oblique reinforcing ribs arranged obliquely, and a first bending part connecting end portions of two adjacent first oblique reinforcing ribs; the second reinforcing rib comprises a plurality of second oblique reinforcing ribs arranged obliquely, and a second bending part connecting end portions of two adjacent second oblique reinforcing ribs; and the first bending part overlaps the second bending part.
[0010] Preferably, an area enclosed between each adjacent first oblique reinforcing rib and each adjacent second oblique reinforcing rib forms a mesh under planar projection.
[0011] Preferably, a support beam is fixedly arranged on the bottom of the screen frame in a transverse and longitudinal staggered manner, and the second reinforcing rib abuts against the support beam.
[0012] Preferably, a fixed cross beam fixed to the screen frame is arranged at the bottom of the discharging end of the screen frame, and the bottom of the screen frame is connected to the fixed cross beam through an elastic member.
[0013] Preferably, the two sides of the feeding end of the screen frame are rotatably connected to the screen frame through a rotating member.
[0014] Preferably, the discharging end of the screen frame extends downward to form an extension part, and the extension part wraps the fixed cross beam.
[0015] Beneficial effects
[0016] By using the ore separation vibrating screen, the screen assembly is composed of the first reinforcing rib and the second reinforcing rib arranged separately, and the two are arranged independently. When the mesh is blocked by ore, the first reinforcing rib will deform in the middle due to the vibration force because the two ends are fixed, causing the mesh to change in aperture by a small amount, and then causing the blocked ore to fall off. When the first reinforcing rib deforms due to the vibration force, the jumping effect will occur, and the repeated jumping will continuously cause the first bending part to hit the second bending part, causing the first reinforcing rib and the second reinforcing rib to vibrate. This vibration effect can effectively force the blocked ore to separate and fall off, thereby keeping the screen mesh unblocked. By adopting this design, the continuity and stability of the screening process are ensured, the downtime caused by mesh blockage is reduced, the production efficiency is improved, the frequency and labor intensity of manual cleaning of the mesh are reduced, and the labor cost is saved.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. As long as the effects of the utility model can be achieved, various changes can be made to the implementation solutions.
[0024] By the personnel in the art, the parts in the case are sequentially connected, and the specific connection and operation sequence should be referred to the following working principle. The detailed connection means is the known technology in the art, and the following mainly introduces the working principle and process.
[0025] Reference Figures 1-4 The ore separation vibrating screen of the embodiment is described. The vibrating screen is used for rough screening of ores. It mainly comprises a screen frame 1, a screen assembly 2 arranged in the screen frame 1, and a lower layer material guide plate 3 arranged below the screen assembly 2. The smaller blocky ores screened out by the screen assembly 2 fall into the lower layer material guide plate 3 and are output, while the larger blocky ores larger than the screen assembly 2 fall along the screen assembly 2 and are output.
[0026] Specifically, as shown in Figure 1 and Figure 2 , the screen assembly 2 is not a whole continuous screen, but comprises a plurality of screen units arranged in sequence from the material inlet to the material outlet and inclined, and the discharge end of each screen unit is suspended above the material inlet of the next screen unit, so that the ore slides from the bottom discharge end to the next screen unit after being screened on a screen unit, and the ore can form a falling potential energy when passing through each screen unit, so that the ore impacts the next screen unit in the multiple falling process in the vibrating state, to prevent the ore from being blocked.
[0027] Specifically, each screen unit comprises a screen frame 23, the inside of the screen frame 23 is hollow, and the bottom of the hollow part is provided with a continuous curved second reinforcing rib 26 along the direction of the ore flow; the hollow part of the screen frame 23 is fixed with an inner screen frame 24, the inner screen frame 24 is provided with a continuous curved first reinforcing rib 25 along the direction of the ore flow, the first reinforcing rib 25 is located above the second reinforcing rib 26, and a mesh 27 is formed between the first reinforcing rib 25 and the second reinforcing rib 26. The combination of the first reinforcing rib 25 and the second reinforcing rib 26 forms a screen for screening ore, and the first reinforcing rib 25 and the second reinforcing rib 26 are independently arranged, and the two ends of the two reinforcing ribs are fixed. When the mesh 27 is blocked by ore, the first reinforcing rib 25 will deform due to the vibration force, causing the mesh 27 to change in size, and then the blocked ore will fall off.
[0028] Further, the first reinforcing rib 25 comprises a plurality of first inclined ribs 251 arranged obliquely and a first bending part 252 connecting the ends of two adjacent first inclined ribs 251; the second reinforcing rib 26 comprises a plurality of second inclined ribs 261 arranged obliquely and a second bending part 262 connecting the ends of two adjacent second inclined ribs 261; and the first bending part 252 overlaps the second bending part 262. When the first reinforcing rib 25 deforms due to the vibration force, it will jump, that is, the first bending part 252 will be separated from the second bending part 262. The repeated jumping will continuously cause the first bending part 252 to hit the second bending part 262, causing the first reinforcing rib 25 and the second reinforcing rib 26 to vibrate, and further forcing the blocked ore to fall off.
[0029] The mesh 27 is the area enclosed between each adjacent first inclined rib 251 and each adjacent second inclined rib 261 in the top view projection of the first reinforcing rib 25 and the second reinforcing rib 26.
[0030] In a preferred embodiment, support beams 28 are fixedly arranged on the bottom of the screen frame 23 in a staggered manner in the transverse and longitudinal directions, and the second reinforcing rib 26 abuts against the support beam 28. The support beam 28 supports the second reinforcing rib 26, thereby improving the strength of the screen.
[0031] In the present embodiment, the two sides of the feed end of the screen frame 23 are rotationally connected to the screen frame 1 by a rotating part 28. The discharge end of the screen frame 23 is provided with a fixed cross beam 21 fixed to the screen frame 1, and the bottom of the screen frame 23 is connected to the fixed cross beam 21 by an elastic part 22, which is a spring. When installed, a protective sleeve can be sleeved around the elastic part 22 to prevent small particles of ore from entering the inside and affecting the work. The design of the rotating part 28 and the elastic part 22 can make the screen frame 23 vibrate by itself through the elastic part 22 when the screen frame 1 drives the screen unit to vibrate, thereby improving the vibration effect and the screening efficiency, and effectively preventing the occurrence of blockage.
[0032] Further, the lower end of the screen frame 23 extends downward to form an extension, the extension is located on both sides of the lower end of the screen frame 23, and the extension wraps around the front and rear ends of the fixed cross beam 21 to prevent small particle ores from entering the space between the lower end of the screen frame 23 and the fixed cross beam 21 and affecting the operation of the elastic member 22.
[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
