Problems solved by technology

[0002] Horizontal centrifuges are widely used in the dehydration of clean coal and medium coal in coal preparation plants. The dehydration effect directly affects the follow-up slime recovery. After a long time of use, water and materials wash away the screen basket mouth of the casing for a long time, causing the casing Wear and tear will increase the gap between the screen basket mouth and the casing, causing some particles to enter the centrifuge tube from the gap between the screen basket and the casing, resulting in coarse running. When the centrifuge runs seriously, it will cause coal The deterioration of the muddy water system has brought a great burden to the subsequent slime water treatment, greatly increased the cost of slime recycling, and even caused environmental protection incidents caused by the overflow of slime water, which has brought adverse effects on production and caused additional workload

Embodiment 1

[0023] Such as figure 1 , figure 2 Shown is a horizontal centrifuge anti-run rough device provided by the present invention, which includes a connecting part used to connect with the horizontal centrifuge and rotate with the main shaft 400, and a smearing part connected to the connecting part, and the smearing part passes through With the rotation of the main shaft 400 of the horizontal centrifuge, the wear-resistant granular glue is applied to the smearing surface of the boss 300 of the horizontal centrifuge to realize the anti-running of the horizontal centrifuge.

[0024] Specifically, the smearing part includes a rotating rod 210 connected to the connecting part, a squeegee 220 arranged on the end of the rotating rod 210 for applying glue to the smearing surface, and the squeegee 220 is arranged at least on the rotating rod 210 at one end.

[0025] Specifically, the connecting end of the rotating rod 210 and the squeegee 220 is provided with an accommodating space 211 f...

Embodiment 2

[0041] The part of this solution that is the same as that of Embodiment 1 will not be described in detail. The rotating rod 210 is not provided with an accommodating space 211 for accommodating the glue injection hole. It is connected to the main shaft 400 of the horizontal centrifuge by bolts, and then the extension rod 120 and the rotating rod 210 are extended to the corresponding scale according to the model of the horizontal centrifuge. When the horizontal centrifuge to be maintained has no corresponding scale, the extension The extended length of the long rod 120 is the distance from the outer edge of the fixed plate 110 to the inner side of the screen basket mouth. The extended length of the rotating rod 210 is adjusted according to the diameter of the edge of the unworn horizontal centrifuge boss 300, and then the wear-resistant granular glue is applied to the horizontal centrifuge. On the edge of the boss 300 of the horizontal centrifuge, when the main shaft 400 drives ...

Abstract

The invention discloses a coarse particle escape prevention device for a horizontal centrifuge. The coarse material running prevention device comprises a connecting part and a smearing part, wherein the connecting part is used for being connected to the horizontal centrifuge and rotating along with a main shaft, and the smearing part is connected to the connecting part; and the smearing part smears abrasion-resistant pimpled rubber on the smearing surface of a boss of the horizontal centrifuge along with rotation of the main shaft of the horizontal centrifuge so as to realize coarse particle escape prevention of the horizontal centrifuge. According to the coarse material running prevention device, abrasion of the horizontal centrifuge can be rapidly and accurately maintained, a gap betweena screen basket opening and a machine shell is decreased, the phenomena that coarse particle escape is caused due to the fact that the gap is too large, and consequently slime water is deteriorated can be avoided, the recycling cost of coal slime is lowered, meanwhile, automatic maintenance can be realized in the whole maintenance process, and therefore errors caused by manual measurement and maintenance are avoided, and the workload of workers is reduced.
