Description
Technical field
The utility model relates to a kind of coal separation and uses the sieve bend feeding device.
Background technology
Sieve bend has stronger Jie's sluicing preliminary treatment effect of letting out, and therefore in the sink float coal works, is used widely.Sieve bend tradition enter material way adopts Material collecting box for harvesting directly to be expected screen surface, and causes pan feeding inhomogeneous easily; Slip feeds sieve bend sieve nest middle part along straight line, thereby has reduced the utilization of sieve bend sieve nest effective area, reduces the de-mediated water separation capability of equipment, influences the quality of product, has reduced productivity ratio.And the direct impact screen net surface of larger particles in the slip is accelerated the compass screen surface infringement, has reduced the life-span of screen cloth, increases operation cost indirectly.
Summary of the invention
The purpose of the utility model provides a kind of coal separation with de-mediated dehydration sieve bend feeding device, can improve the de-mediated dehydrating effect of sieve bend through this device, the quality with product of further boosting productivity.
The utility model realizes that the technical scheme of above-mentioned purpose is:
A kind of coal separation is with de-mediated dehydration sieve bend feeding device; Described feeding device comprises feeding pipe, Material collecting box for harvesting and sieve bend, and described feeding pipe is fixed on the last boxboard of Material collecting box for harvesting, and feeding pipe is connected with Material collecting box for harvesting; Front end near Material collecting box for harvesting in the described Material collecting box for harvesting vertically is provided with baffle plate; Two sidewalls and the box plate that parallel with the slip flow direction in the Material collecting box for harvesting all are fixedly connected with baffle plate, are provided with interval S between the inner surface of the upper surface of described baffle plate and the last boxboard of Material collecting box for harvesting, described interval S=45-55mm; The front end that is positioned at Material collecting box for harvesting on the box plate of Material collecting box for harvesting offers discharge gate, and the discharge gate of Material collecting box for harvesting is fixedly connected with an end of sieve bend.
The profile of described Material collecting box for harvesting is a cuboid, and described baffle plate is the rectangle baffle plate.
Described discharge gate is offered along the width of cuboid Material collecting box for harvesting, and the width of discharge gate is 20-25mm.
The effect of the utility model: the utility model is set up a baffle plate in Material collecting box for harvesting inside, between the inner surface of baffle plate boxboard on the Material collecting box for harvesting 45-55mm gap is arranged, through the interception function of baffle plate; Pan feeding ore pulp (abbreviation slip) baffle plate of flowing through reduces the flow velocity of slip, thereby forms uniform and stable overflow; Make slip flow through Material collecting box for harvesting uniformly and stably; Feed the sieve bend compass screen surface through Material collecting box for harvesting front end discharge gate along tangent line, increase the area that utilizes of compass screen surface, thereby improved the de-mediated water separation capability of sieve bend; Reduce sink float coal works dielectric dissipation, practiced thrift the washing cost.Overcome the sieve bend pan feeding and fed shortcoming and impact sieve plate and screen area are not fully utilized etc. along straight line; The wearing and tearing that compass screen surface is directly washed away by ore pulp have been alleviated simultaneously; Reduced compass screen surface infringement probability; Improve the service life of sieve bend, reduced production cost indirectly, improved the quality of productivity ratio and product.
