Description

Novel anti-blocking polyurethane screen

Technical Field

The utility model relates to the technical field of screens, in particular to a novel anti-blocking polyurethane screen.

Background

A screen is a device for screening, filtering, separating materials, which is generally made of materials such as wires, polymers, fibers, etc., and has uniform mesh openings for classifying solid particles according to size or separating solid particles from liquid;

the mesh size and shape of the screen can be customized according to the needs, common square holes, round holes, rectangular holes and the like are formed, different screening effects can be realized by different screen apertures, and screening requirements of different granularities are met from coarse screening to fine screening;

In the use process of the existing screen, as the heights of the screen ribs at the sides of the screen holes are the same, materials clamped in the screen holes are subjected to the same clamping force, so that the materials are blocked in the screen holes.

Disclosure of utility model

Aiming at the defects of the prior art, the utility model provides a novel anti-blocking polyurethane screen, which solves the problems proposed by the background art.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the novel anti-blocking polyurethane screen comprises an outer frame, wherein a plurality of transverse reinforcing ribs and a plurality of vertical reinforcing ribs are distributed on the inner side of the outer frame, and are distributed on the inner side of the outer frame in an equidistant and staggered manner, and the outer frame is divided into a plurality of rectangular areas;

The upper surface of frame is located a plurality of all offer a plurality of sieve meshes in the rectangle district, every the both sides limit of sieve mesh all is provided with the sieve muscle.

As a further technical scheme of the utility model, the outer frame, the transverse reinforcing ribs and the vertical reinforcing ribs are of an integral injection molding structure and are all made of polyurethane.

As a further technical scheme of the utility model, the size of the screen ribs on one side of the screen holes is long, and the size of the screen ribs on the other side of the screen holes is short.

The utility model provides a novel anti-blocking polyurethane screen, which has the following advantages compared with the prior art

The beneficial effects are that:

The novel anti-blocking polyurethane screen is made of polyurethane, is integrally injection molded, is light and wear-resistant, has excellent elasticity and toughness, and simultaneously has wear resistance and corrosion resistance, can be used for a long time in screening operations of coal, sand and the like, and ensures the service life of the screen;

Secondly, the screen ribs on two sides of the screen hole of the design are high and low, so that when materials are discharged from the screen hole, the materials clamped in the screen hole can be extruded out of the screen hole due to different clamping forces, and meanwhile, the materials clamped in the screen hole can be blocked in the screen hole due to the same clamping force if the two screen ribs are as high as each other.

FIG. 1 is a schematic structural view of a novel anti-blocking polyurethane screen;

FIG. 2 is a schematic view of the bottom structure of a novel anti-blocking polyurethane screen;

FIG. 3 is a cross-sectional view of a novel anti-blocking polyurethane screen.

In the figure: 1. an outer frame; 2. transverse reinforcing ribs; 3. vertical reinforcing ribs; 4. screening holes; 41. and (5) sieving ribs.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.

Referring to fig. 1-3, the utility model provides a novel anti-blocking polyurethane screen technical scheme: the utility model provides a novel prevent stifled polyurethane screen cloth, including frame 1, the inboard of frame 1 distributes has a plurality of horizontal strengthening ribs 2 and a plurality of vertical strengthening ribs 3, horizontal strengthening rib 2 and vertical strengthening rib 3 equidistant crisscross distribution are inboard at frame 1, horizontal strengthening rib 2 and vertical strengthening rib 3 injection moulding structure as an organic whole, not only light, wear-resisting, whole screen cloth possesses corrosion-resistant and high temperature resistant characteristic moreover, and the whole polyurethane material that adopts of screen cloth of this design can make the whole elasticity and the toughness that have of screen cloth, can effectively prevent the jam and the damage of screen cloth, has longer life simultaneously.

The equidistant staggered distribution of horizontal strengthening rib 2 and vertical strengthening rib 3 can separate frame 1 and form a plurality of rectangle regions, a plurality of sieve meshes 4 have all been seted up to the upper surface of frame 1 in a plurality of rectangle regions, the internal diameter of sieve mesh 4 is from top to bottom increased gradually moreover, utilize horizontal strengthening rib 2 and vertical strengthening rib 3 can improve the global toughness of screen cloth, ensure that it uses non-deformable for a long time, and with the internal diameter design of screen cloth hole 4 increase gradually (the aperture from top to bottom grow gradually) the mode, can ensure that the material is by screen cloth hole 4 unloading more smooth and easy.

The working principle of the utility model is as follows: according to the use requirement, the shape of the corresponding sieve mesh 4 can be selected, the sieve mesh is integrally injection molded by a sieve mesh die, and the sieve mesh is made of polyurethane, so that the sieve mesh has stronger toughness and elasticity, is light and is wear-resistant;

Secondly, the two sides of each screen hole 4 are provided with screen ribs 41, the screen ribs 41 on one side of the screen hole 4 are long in size (i.e. high screen ribs), the screen ribs 41 on the other side are short in size (i.e. low screen ribs), and further, as shown in fig. 3, the sizes of every two adjacent screen ribs 41 are different, namely, one high screen rib and one low screen rib, so that the purpose of the design is that: the material stuck in the screen holes 4 can be squeezed out of the screen holes 4 due to different clamping forces generated by the screen ribs 41 with different sizes, and simultaneously the material stuck in the screen holes 4 is blocked in the screen holes 4 due to the same clamping force if the two screen ribs 41 are as high as each other.

The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention. Structures, devices and methods of operation not specifically described and illustrated in the present application are all implemented by conventional means in the art unless specifically indicated and limited.
