A horizontal vibrating centrifugal dehydrator screen basket

Abstract

The invention relates to the technical field of dehydrators, and discloses a screen basket of a horizontal vibrating centrifugal dehydrator, comprising a small ring, one side of the small ring is fixedly mounted with a connecting rod, and one end of the connecting rod is fixedly mounted with a large ring , one side of the small mouth ring is fixed with a bottom ring through a nut, one side of the bottom ring is fixed with a side wall, one side of the bottom ring is fixed with a baffle plate, and the screen of the horizontal vibrating centrifugal dehydrator Basket, by changing the flat structure of the traditional screen, the screen is set at one end of the large mouth ring into a structure with a certain degree of depression, which can make the water flow on the inner wall of the screen basket at the turning point from the flat surface to the non-flat surface. A sudden change process makes the centrifugal force of the accumulated water flow from the end of the small mouth ring to the turning point increase sharply here, which can ensure that the water flow on the inner wall can basically escape from here and ensure that there will be no water flow in the finished product Entry affects the quality of the finished product.

Description

technical field [0001] The invention relates to the technical field of dehydrators, in particular to a screen basket of a horizontal vibrating centrifugal dehydrator. Background technique [0002] In the coal washing industry, coal needs to be dehydrated. There are roughly two types of existing dehydration equipment: horizontal vibrating centrifuge and vertical scraper unloading centrifuge. The advantages of small space, low initial investment, and low energy consumption are widely used. It mainly drives the screen basket to rotate and vibrate through the vibration motor, so that the coal is centrifugally moved in the screen basket to remove the water in it. The coal can slide down and collect along the inner wall of the screen basket, but there are always some problems in the screen basket of the existing horizontal vibrating centrifugal dehydrator: [0003] 1. The existing sieve basket only uses the intermediate support structure to install the screen mesh of the sieve ba...

Problems solved by technology

[0003] 1. The existing sieve basket only uses the intermediate support structure to install the screen mesh of the sieve basket between the large-diameter ring and the small-diameter ring, so that the height of the outer edge of the large-diameter end of the sieve basket is equal to the height of the sieve bar at the large-diameter end The inner wall of the entire sieve basket is a flat surface. When the equipment is working, under the action of centrifugal force, when the water in the material is discharged through the sieve, it is inevitable that some water will flow along the tapered and flat inner wall of the sieve basket. Downflow, thus entering the dry material, affecting the quality of the product

[0004] 2. The feeding of the existing sieve basket is to convey the material to one end of the small-diameter ring of the sieve basket through the upper feeding port. With the high-speed rotation of the sieve basket, the material is scattered on the inner wall of the sieve basket, but this feeding method will When the material is in contact with the high-speed rotating sieve basket, it is knocked away by the inner wall of the sieve basket or the existing materials on the inner wall, resulting in the phenomenon of material splashing in the sieve basket, which leads to a part of the material not being dehydrated by centrifugation. It is because it directly falls into the finished product after being knocked into the discharge port, which seriously affects the quality of the finished product, and this feeding method will also make the material distribution on the sieve basket uneven, resulting in thick material The dehydration is not complete in some places, but the dehydration is too complete in places where the material is thin, which further affects the quality of the finished product
