Abstract
The utility model relates to a grid screen of a stepped screening surface, which comprises a support frame, a first section material guide plate, a second section material guide plate, a first group of sieve bars, a second group of sieve bars and a one-way fixing bolt, wherein the material guide plate is fixed on the support frame, the first group of sieve bars are installed below the first section material guide plate, the second group of sieve bars are installed below the second section material guide plate, one ends of the sieve bars are fixed together through the one-way fixing bolt, and one end is arranged in a suspension way; the second section of material guide plate is arranged below one suspended end of the first group of screen bars. The device has reasonable structural design, good screening effect and long service life, and can be widely used for screening operation of materials.
Description
Technical field
The utility model relates to a kind of screening plant, particularly relates to a kind of castor bar grizzl(e)y of staged screening face.
Background technology
The castor bar grizzl(e)y is the equipment that is used for the coke sieve classification in the domestic coking industry.It need not any driving force when material is sieved, be a kind of screening plant of not consumes energy.Its principle is to utilize the drop of material, carries out in material slips over the process of compass screen surface naturally that sieve classification handles.For guaranteeing the grading effect of material, just need grating to have enough length, but, grating is long more, and intensity is relatively just low more, for keeping the linearity in the grating use, will in grating, increase crosswise fixed, the anchor point that is located at like this in the compass screen surface will be subjected to the strong impact wear of material, and reduce service life, influence screening effect.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and screening effect is good, the castor bar grizzl(e)y of the staged screening face of long service life.
In order to address the above problem, the utility model by the following technical solutions:
A kind of castor bar grizzl(e)y of staged screening face, comprise bracing frame, first section stock guide, second section stock guide, first group of grating, second group of grating and unidirectional set bolt, stock guide is fixed on the bracing frame, first group of grating installed in first section stock guide below, second group of grating installed in second section stock guide below, each is organized grating one end and is fixed together by unidirectional set bolt, the unsettled setting of an end; Second section stock guide is arranged on the below of first group of unsettled end of grating.
Difference in height Δ H=150～200mm between described two groups of gratings.
Compared with prior art, the beneficial effects of the utility model are:
1, the whole compass screen surface of the utility model device is made up of two groups of gratings, and then the length of every section grating shortens relatively, thereby has improved the intensity of grating, prevents that grating from deforming, and improved screening effect.
2, every group of grating of the utility model device adopts unidirectional location, two sections compass screen surfaces are staged handing-over, do not add fixtures such as crossbeam between two compass screen surfaces, material by the time do not have an additional horizontal screen frames resistance, the grating wearing and tearing alleviate, and are difficult in the screening process feeding in raw material, and make that screening is more smooth and easy, not only improve screening effect, also effectively prolonged the service life of grating.
3, the utility model compass screen surface is made up of two groups of gratings, the screening part volume-diminished of installing/dismounting, make maintenance, change more conveniently, effectively alleviate maintenance personal's labour intensity, improved overhaul efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
The utility model device with an all-in-one-piece screening face, is divided into stepped two material screening faces on the screening working face of same material screening specification.
A kind of castor bar grizzl(e)y of staged screening face, as shown in Figure 1, comprise bracing frame 1, first section stock guide 2, second section stock guide 6, first group of grating 4, second group of grating 5 and unidirectional set bolt 3, stock guide is fixed on the bracing frame 1, first group of grating 4 installed in first section stock guide 2 below, second group of grating 5 installed in second section stock guide 6 below, and each is organized grating one end and is fixed together by unidirectional set bolt 3, the unsettled setting of an end; Second section stock guide 6 is arranged on the below of first group of grating 4 unsettled end, makes that the two ends compass screen surface is end to end.Difference in height Δ H=150～200mm between the two screening faces.The width of stock guide is not less than 500mm, guarantees directly not impact on grating when material falls, but drops on earlier on the stock guide, slips into compass screen surface again.The fixedly employing of grating is unidirectional fixed, and with all fixing point Hide Alls in the bottom of entity stock guide, do not worn and torn by material.The screening spacing of adjacent two gratings adopts spacer block adjustment location.
Claims (2)
1. the castor bar grizzl(e)y of staged screening face, it is characterized in that, comprise bracing frame, first section stock guide, second section stock guide, first group of grating, second group of grating and unidirectional set bolt, stock guide is fixed on the bracing frame, first group of grating installed in first section stock guide below, second group of grating installed in second section stock guide below, and each is organized grating one end and is fixed together by unidirectional set bolt, the unsettled setting of an end; Second section stock guide is arranged on the below of first group of unsettled end of grating.
2. the castor bar grizzl(e)y of a kind of staged screening face according to claim 1 is characterized in that the difference in height Δ H=150～200mm between described two groups of gratings.
