Problems solved by technology

[0008] Aiming at the problem that the sieve plate of the existing pulper is easily deformed by the extrusion of the pulp during use, the present invention provides an anti-deformation sieve plate for a pulper, and the sieve plate is improved by arranging support bars on the sieve plate. Strength, effectively reducing the probability of the sieve plate being squeezed and deformed by the slurry, and can reduce the thickness of the sieve plate

Embodiment 1

[0037] Such as figure 1 As shown, this embodiment provides an anti-deformation sieve plate for a pulper, which includes a circular sieve plate body 1 and support bars 3; wherein, the surface of the sieve plate body 1 is provided with sieve holes 2, and the support bars The strips 3 are arranged in pairs on the front and back sides of the sieve plate body 1 . In this embodiment, the support bar 3 is a rectangular plate-shaped structure, a plurality of support bars 3 are distributed in a spiral shape on the side of the sieve plate body 1, and the two opposite support bars 3 on the front and back sides of the sieve plate body 1 cross Staggered settings. In this structural form, the support bars 3 strengthen the sieve plate body 1, and the support bars 2 on the front and back sides are arranged in a cross shape, which has mutual pulling effect, and is squeezed by the slurry on one side of the sieve plate body 1. When pressing, the support bar 2 produces opposite tensile force, w...

Embodiment 2

[0041] This embodiment provides an anti-deformation sieve plate for a pulper, which is basically the same as Embodiment 1, except that: figure 2 As shown, the support strips 3 on both sides of the sieve plate body 1 are in the shape of a "Z" plate, and a plurality of support strips 3 are evenly distributed in the circumferential direction on the side of the sieve plate body 1, and the front and back sides of the sieve plate body 1 The upper relative two supporting bars 3 are arranged crosswise. Such a structure further increases the connection strength between the support bar 3 and the sieve plate body 1, and its effect is better than that of Embodiment 1.

Embodiment 3

[0043] This embodiment provides an anti-deformation sieve plate for a pulper, which is basically the same as Embodiment 1, except that: image 3 As shown, the support bars 3 on both sides of the sieve plate body 1 are corrugated annular plates, one is provided on each side of the sieve plate body 1, and the crests of the two support bars 3 are opposite to the troughs, forming a staggered arrangement. This structure further increases the connection strength between the support bar 3 and the sieve plate body 1, and its effect is better than that of Embodiment 1 and Embodiment 2.

Abstract

The invention discloses an anti-deformation sieve plate used for a pulper, and belongs to the field of pulper accessories. The sieve plate comprises a circular ring-shaped sieve plate body and supporting bars; the surface of the sieve plate body is provided with sieve holes; the supporting bars are arranged in pairs on the positive and negative side surfaces of the sieve plate body; each supporting bar has a rectangular plate-like structure, a ''Z''-shaped plate-like structure or a wave-shaped annular-plate structure; and the sieve plate body is formed by splicing of two semi-annular plates, and has a material of 0Cr17Ni4Cu4Nb and a thickness of 15.5 to 15.8 mm. According to the sieve plate disclosed by the invention, the supporting bars are arranged on the sieve plate body, so that the strength of the sieve plate is improved, the probability of deformation of the sieve plate caused by extrusion of slurry is effectively reduced, the thickness of the sieve plate is reduced, and the production costs are reduced.

Description

technical field [0001] The invention belongs to the field of pulper accessories, and more specifically relates to an anti-deformation sieve plate for a pulper. Background technique [0002] In the paper industry, the hydraulic pulper is one of the most commonly used pulping equipment in the pulp and paper industry. It mainly crushes pulp boards, waste books, waste cartons and other waste items. In the process of recycling, it must be Repulp waste paper, old newspapers or other waste paper products to ensure the normal operation of subsequent production equipment and the purity of finished products. The purpose of waste paper pulping is to eliminate fiber bundles without cutting or avoid cutting fibers as much as possible, while trying not to destroy various non-fibrous impurities. [0003] At present, there are two kinds of pulpers without sieve plate and those with sieve plate. The one without sieve plate can only be used for intermittent pulping, that is, the pulp will no...
