Description

A kind of vertical coal slurry dewaterer
Technical field
The present invention relates to a kind of vertical coal slurry dewaterers, belong to technical field of solid-liquid separation equipment.
Background technology
The coal preparation plant now run, main dehydration equipment have cyclone, vacuum filter, raker thickener etc..For pressure Workshop is filtered, the dewatering machine of generally use is exactly mainly this equipment of filter press.The underflow of raker thickener is carried out in press filtration workshop Material is handled, and final coal slime is press-filtered out, and the moisture filtered out enters the water circulation system of entire coal preparation plant, is recycled.Press filtration The dehydrating effect of machine is relatively preferable, can finally recycle coal slime, but since it belongs to discontinuous working method, each pressure-filtering process Will recycle fed, press filtration, very complicated operation such as discharging.This not only has higher behaviour to the operating personnel of filter press It is required, and the work period is too long, working efficiency is low, is not suitable for the situation of continuous processing black water.Therefore in this feelings Under condition, in order to mitigate the working strength and pressure of coal preparation plant's press filtration workshop operating personnel, in order to improve the efficiency of press filtration, coal is improved The efficiency of muddy water recycling, solve the disadvantage that filter press can not continuous work, the present invention devises a kind of spiral of high dehydration rate Sieve dewaterer.
It is exactly mainly to borrow coal slime dewatering equipment to carry out black water using the method that mechanical force carries out black water dehydration Dehydration.Common coal slime mechanical dehydration mode has filtering, press filtration, belt press filtration and decanter type centrifugal dehydration etc..
Sedimentation-type centrifuge is dehydrated by centrifugal force, and the acquisition of centrifugal force is produced by body revolution at a high speed It is raw.Under most the using of centrifugal force that high speed generates, the coal of greater density is thrown toward the rotating cylinder inwall of centrifuge, and then is turned by spiral Son scrapes, and completes dewatering operation.
Screen bowl centrifuge be on the basis of sedimentation centrifuge increase fillter section and it is manufactured.In sedimentation centrifuge On the basis of effect, under the action of the centrifugal force, moisture therein is passed through and then is deviate from by sieve the sediment filter cake settled, at this time Filter cake moisture can reach 13-22%.
Experiment shows:If higher than vacuum filter for the dehydration rate of black water using decanter type filtering centrifuge 4% or so, it is also very effective for the reduction of ash of filting cake, 10% level can be reached.But it is also defective, be exactly for The recycling of solids is low compared with filter, it is clear that allows for a large amount of fine coal slurry and enters in recirculated water.
As the equipment earliest for black water dehydration, vacuum filter has obtained widely answering at present in coal preparation plant With.Vacuum filter is the mechanical advantage by fluid, when black water flows in gap, negative pressure meeting caused by vacuum pump Overcome the flow resistance of filtrate, moisture that will be extracted.
Vacuum filter and pressure filtration make a big difference.First, vacuum filter is for destroying coal surface water Stress than the pressure effect under pressurized condition is more prone to that coal surface moisture is made to deviate from.Secondly as the viscous force characteristic of water, It is increased with pressure increase, so under vacuum, the viscous force of water is reduced, dehydrating effect is notable.Finally, by What it is in vacuum hydroextractor generation is negative pressure, and the requirement to equipment is very high, and which limits further increasing for its water separation capability.
Recent years, requirement of the country for environmental protection is higher and higher, the recycling requirement for coal preparation plant's final products It is higher and higher.Filter press can be fallen black water final process, and then obtained the wide of coal preparation plant with its unique processing mode General application becomes the terminal device for completing coal separation station-service water closed cycle.
Invention content
Present invention mainly solves the technical issues of:It is unable to continuous feed, treating capacity and treatment effeciency for existing dewaterer Relatively low, the problem of greatly affected coal preparation plant's production cost and production efficiency, it is de- that the present invention provides a kind of vertical coal slurries Water dispenser.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention:
A kind of vertical coal slurry dewaterer, including holder, loading hopper and sieve, the loading hopper are arranged on holder Side, loading hopper lower section are rotating device, are feed inlet inside rotating device, rotating device both sides are provided with runing rest, revolve Turn to be provided with sliding rail between holder and holder, milling roller, sieve setting are provided between runing rest and rotating device Below rotating device, screen bottom is provided with drainage pipeline.
A kind of application process of vertical coal slurry dewaterer is:The coal slime being dehydrated will be needed to be added through loading hopper, coal slime warp Feed inlet below rotating device is fallen on sieve, and rotating device drives milling roller to be moved in screen surface by runing rest, Coal slime falls along screen surface under the effect of gravity, is laid in screen surface, milling roller is during exercise by the coal slime of screen surface It rolls, coal slime sloughs moisture under squeezing action, and the sewage of abjection is discharged through the drainage pipeline below sieve, dewatered coal slime Then it is stored in frame bottom.
The sieve is tapered, and angle of inclination is 30 ~ 45 °.
The milling roller and runing rest is both provided with two groups, and is arranged symmetrically in rotating device both sides.
The beneficial effects of the invention are as follows:
Coal slime is dehydrated by the way of press filtration in the present invention, a kind of taper sieve is devised in the present invention, coal slime adds Material mouth is arranged in the top of taper sieve so that is laid in conical screen netlist when coal slime enters taper sieve under the effect of gravity Face is provided with the milling roller that is rotated around taper sieve in taper screen surface in the present invention, passes through the milling roller pair constantly moved Coal slime carries out the effect of rolling, and to remove the moisture content in coal slime, efficiently solves existing filter-press type coal in this way Mud dehydration device can not continuous feed, the low problem of dehydration efficiency effectively increases the rate and quality of coal slime dewatering, and this Invention device is simple in structure, and low energy consumption, effectively reduces production cost.
