Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Figures 1 to 3 , a polyurethane screen basket, comprising a frame body 1 and n sieve plates 3 arranged on the frame body 1, the frame body 1 comprising a bottom frame 101, a top frame 102 and n connecting the bottom frame 101 and the top frame 102 For the spokes 4, a sieve plate 3 is respectively disposed between two adjacent spokes 4, and the two sides of the sieve plate 3 are respectively fixedly connected with the spokes 4; n is a natural number greater than or equal to 2. Here, the sieve plate is made of curved polyurethane sieve plate, and the central angle of the sieve plate is The angle between the screen surface of the screen basket and the bottom plane can be designed between 30° and 90°, and the outer diameter of the bottom frame of the screen basket is between 200 and 2000mm.

[0042] When the angle between the screen surf...

Abstract

The invention relates to a polyurethane sieve basket suitable for the industry of screening of black metal, non-ferrous metal, coal, building materials, petrochemical engineering, abrasive material and the like, and a forming method of the polyurethane sieve basket. The polyurethane sieve basket comprises a frame body and n sieve plates arranged on the frame body. The frame body comprises a bottom frame, a top frame and n spokes connecting the bottom frame and the top frame. The sieve plates are arranged between every two adjacent spokes. The two sides of each sieve plate are fixedly connected with the corresponding spokes; and n is a natural number equal to or larger than two. According to the polyurethane sieve basket, an assembly type structure is adopted, the integrally-formed sieve plates are adopted and all installed on the frame body of the sieve basket, and the sieve basket is simple in overall structure and convenient to form; when one sieve plate is abraded, the abraded sieve plate can be replaced independently, so that the maintenance cost is greatly reduced; and the aperture ratio is high, and the service life is long. Meanwhile, the invention further discloses the forming method of the polyurethane sieve basket.

Description

technical field [0001] The invention relates to a polyurethane screen basket suitable for screening industries such as ferrous metals, non-ferrous metals, coal, building materials, petrochemicals, abrasives and the like and a molding method thereof. Background technique [0002] Screen baskets are widely used in pharmaceutical, metallurgy, mining, petrochemical and water treatment fields to select powders or filter liquids. There are two main types of centrifuges used in the coal preparation industry for dewatering final coal, one is a horizontal vibrating centrifuge with vibrating discharge, and the other is a spiral scraper discharge centrifuge, and no matter which type of centrifuge needs to use a screen basket , and the screen basket will directly affect the dehydration effect. At present, most of the screen baskets are made of stainless steel welded screen, which not only has a low opening rate, but also has serious wear and tear on the screen basket and a short servic...
