Abstract

The utility model relates to the washing and separating equipment, particularly a component screen mesh used for grading screens of coal separating plants. The screen mesh is composed of a polyurethane screen mesh layer and a steel plate screen mesh bottom liner layer combined with the polyurethane screen mesh layer or a steel rope mesh embedded in the polyurethane screen mesh layer. The screen mesh has good abrasion resistance, low noise and long service life.

Description

Sizing screen
The utility model relates to washing appliance, particularly a kind of parts screen cloth that is used for coal preparation plant's classifying screen.
At present, the screen cloth of coal preparation plant's classifying screen of prior art adopts the steel plate type screen cloth more.Though this screen cloth is easy to process, wearing no resistance of screen cloth, fragile, and also in the course of the work, owing to colliding mutually with material and rubbing, the noise height influences the healthy of workman.
Purpose of design of the present utility model is to overcome the weak point in the prior art, and provides a kind of anti-wear performance good, and noise is low, the screen cloth of the classifying screen of long service life.
Purpose of design of the present utility model can reach by following measure:
The classifying screen screen cloth has the polyurethane screen layer, the steel screen cloth end liner layer that combines with the polyurethane screen layer is arranged or the wire rope net that is embedded in the polyurethane screen layer constitutes.
Purpose of design of the present utility model can also reach by following measure:
Its steel screen cloth end liner layer adopts the punching hole expanded metal lath, and the diameter of expanded metal lath mesh is equal to or greater than the large aperture of the round taper hole of polyurethane screen layer.
The classifying screen screen cloth be embedded in the steel wire rope that the wire rope net in the polyurethane screen layer adopts parallel longitudinal to set.
The utility model compared with prior art has following advantage:
1. adopt polyurethane screen layer anti-wear performance obviously to improve, noise obviously reduces, long service life.
2. the steel wire rope screen cloth that adopts parallel longitudinal to set, screen cloth self softness, tension performance is good during use, and is not yielding.
3. adopt the punching hole expanded metal lath to make the structure of end liner layer, the bulk strength height,, easy to use during use without tensioning.
The drawing of accompanying drawing is described as follows:
The structural representation front view of Fig. 1: the utility model embodiment 1
The A-A cutaway view of Fig. 2: Fig. 1
The B partial enlarged view of Fig. 3: Fig. 2
The structural representation front view of Fig. 4: the utility model embodiment 2
The C-C cutaway view of Fig. 5: Fig. 4
The D partial enlarged view of Fig. 6: Fig. 5
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Embodiment 1: Fig. 1,2,3 shows a kind of structure of the utility model.The polyurethane screen layer 1 that is covered with round taper hole is done the top layer of screen cloth, and punching hole expanded metal lath 2 is made the structure of end liner layer.Adopt polyurethane material to cast on the punching hole expanded metal lath, or bond with binding agent.The diameter of the mesh of expanded metal lath will equal or be slightly larger than the large aperture of the round taper hole of polyurethane screen layer, the i.e. aperture of bottom surface.The mesh of the two will align.
Embodiment 2: Fig. 4,5,6 shows the another kind of structure of the utility model.Be covered with in the polyurethane screen layer 3 of round taper hole, steel wire rope 4 that parallel longitudinal sets arranged as reinforcement.Polyurethane screen layer 3 adopts polyurethane material casting sulfuration to form.

Claims (3)

1, the classifying screen screen cloth used of a kind of washery is characterized in that having the polyurethane screen layer, the steel screen cloth end liner layer that combines with the polyurethane screen layer is arranged or be embedded in wire rope net in the polyurethane screen layer.
2, classifying screen screen cloth according to claim 1 is characterized in that said steel screen cloth end liner layer is the punching hole expanded metal lath, and the diameter of expanded metal lath mesh is equal to or greater than the large aperture of the round taper hole of polyurethane screen layer.
