Description
Technical field
The present invention relates to a kind of Screen in Coal Preparation Plant subset, single-deck vibrating screen can not changed sieve by specifically one kind
It is changed into the double-decker sieve plate of double deck screen under the premise of body structure.
Background technology
During material screening, because when granularity requirements, which change, needs to sub-elect three kinds of size fractionated products, original is set
The individual layer classifying screen that meter is selected can not just meet production requirement.Existing technical reform scheme is：(1) by single-deck screen close to the port of export
Several groups of sieve plates are replaced by large-holed sieve tray and carry out secondary grading, but such a way causes small grain size sieving area to reduce, screening effect
Fruit weakens；And the sieving area of big grade is not enough, screening effect is not also good, while also needing to reduce the treating capacity of sieve to protect
A certain degree of screening effect is demonstrate,proved, therefore, this scheme can not reach requirement on screening effect and disposal ability；(2) will be single
Layer sieve is replaced by double deck screen, but this formula investing is big, quantities big, time-consuming.
The content of the invention
In order to solve the deficiencies such as prior art screening effect is poor, quantities big, time-consuming, the present invention provide it is a kind of without
On the premise of changing vibratory sieve, original single-deck screen is adapted as to the double-decker sieve plate of double deck screen, realize increase classification level,
Increase sieving area and improve the effect of disposal ability.
The technical scheme of use of solving the above problems is：
A kind of double-decker sieve plate, including the sieve plate on sieve nest, in addition to support clamp rail, bottom clamp rail, described sieve
Plate is divided into upper strata sieve plate and lower floor's sieve plate, and lower floor's sieve plate is with upper strata sieve plate by supporting clamp rail to connect as one, and support clamp rail is made
For the pedestal of upper strata sieve plate, upper strata sieve plate is supported；Bottom clamp rail top coordinates with lower screen plate hook, groove to be closely connected, bottom card
The bottom of rail is connected with sieve nest base.
Preferably：
The bottom of the support clamp rail is provided with neck, and lower screen edges of boards frame top sets card corresponding with support card flange of rail portion neck
Hook, support clamp rail is connected with each other with the grab on lower floor's sieve plate top by neck, and support clamp rail is fixedly connected with lower floor sieve plate
Together, integrative-structure is formed.
The bottom of the support clamp rail is provided with twice neck, and lower screen edges of boards frame upper parallel is set and support card flange of rail portion
The corresponding twice grab of twice neck, supports two pass neck of the clamp rail by bottom side, with and be listed in the twice on lower screen plate top
Grab is connected with each other, and support clamp rail is fixed together with lower floor sieve plate, formation integrative-structure.
The top of the support clamp rail is provided with grab, and the bottom of upper strata sieve plate is provided with neck corresponding with grab, branch
Clamp rail is supportted as the pedestal of upper strata sieve plate, upper strata sieve plate is played a supportive role, and it is close by the neck of grab and upper strata sieve plate
Connection.
The upper parallel of the support clamp rail is provided with twice grab, and the bottom of upper strata sieve plate is provided with and support clamp rail
The corresponding twice neck of twice grab, the twice grab of support clamp rail is closely connected with the twice neck of upper strata sieve plate respectively.
Worn in the middle part of the bottom clamp rail and be connected to bolt, by bolt by the bottom of lower floor's sieve plate and bottom clamp rail, with sieving
The base twist-on of body is fixed.
The sieve aperture of described upper strata sieve plate is more than the sieve aperture of lower floor's sieve plate.
Described bottom clamp rail, support clamp rail, lower floor's sieve plate, the frame of upper strata sieve plate are respectively equipped with bound edge.
Compared with prior art, because the present invention is provided with the sieve plate of double-decker, relative to technical reform scheme (1), small
In the case that sizing area is constant, the big sizing layer of homalographic is added, the screening gross area adds one times, raising
The screening effect of material, increases the disposal ability of vibratory sieve；Relative to technical reform scheme (2), the present invention can not only reach double
The grading effect of layer sieve, and the parts such as upper strata bottom girder are not needed, Structure of Vibrating Screen is simplified, weight of equipment is reduced, reduces
Power consumption, meanwhile, because its cost is low, it is convenient to change, it is more suitable for small-sized screening machine technological transformation.Therefore, needing to existing material
When carrying out multi-layer classification, the present invention is on the premise of technological requirement is met, and small investment, screening effect are good.

Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, with reference in the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described content is this hair
Bright a part of embodiment, rather than whole embodiments.The embodiment of the present invention for generally describing and showing in this figure
Component can be arranged and designed with a variety of configurations.
See accompanying drawing 1, a kind of double-decker sieve plate, including：Bottom clamp rail 1, lower floor's sieve plate 5, support clamp rail 6, upper strata sieve plate
7, double-decker sieve plate is sequentially arranged on sieve nest, is completed by polyurethane one-time-concreting.Concrete structure is：
The bottom of clamp rail 6 is supported to be provided with twice neck, the frame upper parallel of lower floor's sieve plate 5 sets the bottom two with support clamp rail 6
The corresponding grab 4 of road neck, supports two pass neck of the clamp rail 6 by bottom side, with and be listed in the phase of two grab 4 on lower screen plate top
Connect, support clamp rail 6 is fixed together with lower floor sieve plate 5, formation integrative-structure；Support clamp rail 6 is used as upper sieve
The pedestal of plate 7, plays a supportive role to upper strata sieve plate 7.Two layers of sieve plate up and down is separated to form the projectile of substrate material by support clamp rail 6
It is classified space.
The upper parallel of support clamp rail 6 is provided with twice grab, and the bottom of upper strata sieve plate 7 is provided with and support clamp rail 6
The corresponding twice neck of twice grab, support clamp rail 6 plays a supportive role as the pedestal of upper strata sieve plate 7 to upper strata sieve plate 7, and
