Abstract
The utility model discloses a skeleton type net-shaped coal slime dewatering sieve plate, which belongs to the coal separating equipment in coal mines and is mainly used for dewatering vibration screen. The skeleton type net-shaped coal slime dewatering sieve plate adopts a structure that a hexagonal hole stainless steel grille is serviced as a bracket, a double-layer stainless steel screen composed of a bottom layer bearing and an upper layer screen is adhered on the bracket, the pore diameter of the upper layer screen is required to be 0.5 mm, and the wire diameter is required to be 0.22 mm. The mesh of the screen adopts homogeneous square holes, and is not easy to be blocked by fiber fabric; the open hole ratio of the mesh of the screen is larger than 50 percent, and the dewatering effect is good; the mesh openings of the screen are not easy to be distorted but are homogeneous, thus the sieved substances from the screen can meet the requirements for granularity; because the stainless steel grille is adopted as the bracket, the intensity is strong, and the service life is long.
Description
Technical field
The utility model relates to the colliery cleaning unit, relates in particular to the dehydration and vibration sieve.
Background technology
The vibratory sieve of dehydration usefulness mainly was made of sieve plate and framework when colliery coal preparation plant reclaimed foam coal, coal slime at present.Wherein sieve plate is to be made of the stripe board of evenly arranging at interval.Because the sieve plate that stripe board constitutes is the bar shaped split, so easily stopped up, and, influence dehydrating effect because the thickness limits of stripe board makes percent opening be lower than 50% by fibre object, also since stripe board in use be out of shape make crack irregular, cause the sieve top sieve under granularity do not meet product requirement.
Summary of the invention
The utility model proposes a kind of skeleton netted coal slime dewatering sieve plate for solving the above-mentioned deficiency of vibratory sieve dehydration sieve plate.
For achieving the above object, skeleton netted coal slime dewatering sieve plate of the present utility model is made carriage by hexagonal hole stainless steel grid, be bonded with the double-layer stainless steel screen cloth of being made up of bottom holder net and upper strata screen cloth on carriage, the aperture that requires the upper strata screen cloth is 0.5mm, and the silk footpath is 0.22mm
Its good effect is:
1. the mesh of screen cloth is uniform square hole, is difficult for being stopped up by fibre object;
2. the percent opening of screen cloth mesh is greater than 50%, and dehydrating effect is good;
3. the screen cloth mesh is not yielding, evenly, makes sieve go up screenings and meets granularity requirements;
4, owing to adopt the stainless steel grid to make skeleton, intensity is big, long service life.
Description of drawings
Fig. 1 is a front view of the present utility model, has only shown the flat shape structure among the figure.
Among the figure: 1-carriage, 2-upper strata screen cloth, 3-bottom holder net.
The specific embodiment
At first make the double-layer stainless steel screen cloth, the double-layer stainless steel screen cloth is made up of bottom holder net 3 and upper strata screen cloth 2.Requiring the aperture of upper strata screen cloth 2 is 0.5mm, and the silk footpath is 0.22mm; Bottom holder net 3 is 20 orders, and the silk footpath is 0.35mm.The hexagonal hole grid that intercepts stainless steel then is as carriage 1, hexagonal hole stainless steel grid is selected glazing bar width 6mm, thickness 2-3mm for use, hexagonal hole diagonal angle line length 40-60mm, the last organic component of smearing on the contact-making surface of double-layer stainless steel screen cloth strengthens Antirot adhesives, double-layer stainless steel net and carriage 1 are become one, form skeleton netted coal slime dewatering sieve plate of the present utility model.
Claims (2)
1, a kind of skeleton netted coal slime dewatering sieve plate, it is characterized in that it is to make carriage by hexagonal hole stainless steel grid, is bonded with the double-layer stainless steel screen cloth of being made up of bottom holder net and upper strata screen cloth on carriage, requiring the aperture of upper strata screen cloth is 0.5mm, and the silk footpath is 0.22mm.
2, skeleton netted coal slime dewatering sieve plate as claimed in claim 1 is characterized in that, described hexagonal hole stainless steel grid glazing bar width is that 6mm, thickness are 2-3mm, and hexagonal hole diagonal angle line length is 40-60mm; Described bottom holder net is 20 orders, and the silk footpath is 0.35mm.
