Problems solved by technology

[0002] The aforementioned mineral materials mainly refer to non-metallic mineral materials such as limestone, marl, chalk, mudstone, coal and gypsum, which are moist and viscous, because such materials are often mixed with substances with high moisture content and abrasiveness. , so if the substance is not removed in advance and enters the hammer crusher for crushing, the following technical problems are likely to occur: one is to increase the working load of the hammer crusher; the other is to aggravate the wear and sticking of the hammer crusher It may even frequently cause the blockage of the crushing chamber of the hammer crusher; the third is to affect the crushing efficiency of the hammer crusher and inhibit the production capacity; the fourth is to affect energy efficiency, that is, to cause waste of electric energy
[0004] But above-mentioned CN101972684A has the shortcoming of following two respects: one, because the water content of the material mixed in the aforementioned mineral materials such as limestone, marl, chalk, mudstone and the like is quite high and viscous is bigger, thus in practice During the pre-screening process, it is very easy to get stuck. If the machine cannot be stopped and cleaned in time, there is a risk of damage to the power mechanism. , the work intensity of the online workers is significantly increased; secondly, because only the cams on a set of transition rollers and a set of discharge rollers are arranged circularly in a cross-shaped staggered manner, the adjacent transition rollers and the cams on the discharge rollers are ignored. The relationship between the cams on the adjacent discharge rollers is not enough to reflect the ideal fluctuation effect on the material when the pre-screening mechanism is in working condition, and finally affects the screening rate of the unbroken material

Embodiment 1

[0026] See figure 1, a box body 1 that is substantially in a rectangular parallelepiped configuration is given, the upper part, the lower part and the right end of the box cavity 11 of the box body 1 (with figure 1 The position state shown as an example) is not closed, that is, it is formed as an opening, and the left end of the box cavity 11 is formed as a feeding port 111, and the right end is formed as a discharge port 112; a group of screening rollers 2 (also Can be called screening rollers, hereinafter the same), this group of screening rollers 2 follows the length direction of the aforementioned box body 1 from the left end to the right end of the box body cavity 11 (with figure 1 state as an example) are set in the box cavity 11 one by one, and the set of screening rollers 2 are each composed of a screening roller shaft 21, a roller shaft driving sprocket 22, a circular roller sleeve 23 and an oval roller shaft The front shaft head 211 of the screening roller shaft 21 ...

Embodiment 2

[0043] See Figure 6 , Figure 6 Shown are two sets of fluctuating roller screening machines of the present invention with the same structure as in Example 1, and the two sets of fluctuating roller screening machines form a set of high and the other set of low gradient relationship with each other, from the left side (with Figure 6 The shown position state is taken as an example) and then screened by a set of wave roller screens on the right side. Such a configuration can be called two-stage screening, and based on this principle, multi-stage screening can also be formed as needed. All the other are the same as the description to embodiment 1.

Abstract

The invention provides a fluctuating roller type screening machine and belongs to the technical field of mining machines. The fluctuating roller type screening machine comprises a box, a set of screening rollers and a power mechanism. The upper portion, the lower portion and the right end of a box cavity are not closed. A feeding port is formed in the left end, and a discharging port is formed in the right end. The screening rollers are formed by screening roller shafts, roller shaft drive chain wheels and round and oval roller shaft sleeves. A front shaft head of one screening roller shaft is connected with the power mechanism. The screening machine is characterized by further comprising a set of screening roller cleaning plates fixed into the box cavity. The screening roller cleaning plates correspond to the round and oval roller shaft sleeves. The positions of the round and oval roller shaft sleeves on the adjacent screening roller shafts are mutually staggered. The relation of 90-degree staggering is formed between the oval roller shaft sleeves on every two adjacent screening roller shafts. Sticky and wet substances are prevented from sticking to and blocking space between the screening rollers; working intensity is reduced, and the screening working efficiency of the whole machine is guaranteed; materials entering the box cavity can be fluctuated excellently, and the sticky and wet substances adhering to the materials can be separated and stripped by the round and oval roller shaft sleeves easily.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a fluctuating roller screening machine, which is matched with a hammer crusher and screens in advance the ore which is not to be crushed in the ore before entering the hammer crusher. Background technique [0002] The aforementioned mineral materials mainly refer to non-metallic mineral materials such as limestone, marl, chalk, mudstone, coal and gypsum, which are moist and viscous, because such materials are often mixed with substances with high moisture content and abrasiveness. , so if the substance is not removed in advance and enters the hammer crusher for crushing, the following technical problems are likely to occur: one is to increase the working load of the hammer crusher; the other is to aggravate the wear and sticking of the hammer crusher It may even frequently cause the blockage of the crushing working chamber of the hammer crusher; the third is ...
