Description
Technical field
The present invention relates to a kind of Mechanical Method spray membrane process.
Background technology
Filter is to utilize porous filter medium, retains liquid and the solid particle in solid particle mixture, and realizes the equipment that solid, liquid separates.Filter is widely used in the departments such as chemical industry, oil, pharmacy, light industry, food, ore dressing, coal and water process.Screen plate is the core component of ceramic filter.Using inorganic fenestra burning process, utilize capillary theory, form vacuum in plate, energy-conservation effectively separation by the moisture content in slurry is extracted, and is trapped on screen plate by the solid matter in slurry, then strikes off with scraper.
United States Patent (USP) 4863656 relates to a kind of method for manufacturing microwell plate, and discloses the screen plate obtained by the method and utilize the suction drier of this screen plate.The screen plate of this United States Patent (USP) 4863656 includes a pair relative jam wall, and this determines inner space between which to suction walls, and this inner space is full of granular materials.Suction drier apparatus includes at least one screen plate, and this screen plate is mounted to can enter and leave in basin or the like, and material to be dehydrated is arranged in this basin.In one embodiment, suction drier apparatus includes several screen plate, and these screen plates are mounted around the circular arrangement of rotary shaft.Negative pressure is applied in the suction walls of each plate, therefore, and water or the sucking-off from material to be dehydrated of other liquid, and pass through in the inner space in suction walls suction filter plate, then under suction function in sucking-off plate structure.
The about 0.1 bar absolute pressure that micro-porous filtration plate for capillary filter is designed to bear from filter cake manufacture and dry run changes to the continuous pressure of about 2.0 bar absolute pressures in backwash process.Plate allows for bearing the change of this pressure in circulation every time, it means that be of about the compression shock of 500,000 times every year.It is, therefore, apparent that the intensity of micro-porous filtration plate must be high, in order to make plate can use for many years under rather harsh environments.
United States Patent (USP) 5178777 relates to a kind of method for making filter cake take off when being pumped in filter cake, by the filtering surface of filter element, the liquid produced from capillary surface.In this United States Patent (USP) 5178777, on the filtering surface of filter element, form liquid film by the back-pressure by filter element effect, in order to produce the effect of backwashing to screen plate.Particularly, after just producing liquid film, at least one air-flow guides the filtering surface of filter element into, in order to the filter cake being separately positioned on filtering surface.
Except requirement of strength, optimal liquid flowing requires that interior substructure has the minimum pressure drop.This is critically important in the stage forming filter cake, but particular importance in backwash process.Backwash deficiently so that screen plate blocking is too fast, it reduce the performance of filter.And, when the filter plates are clogged, flow resistance increases, the dangerous increase of the impact damage that is under pressure.
Preferably, the screen plate for capillary filter includes: barrier film, and this barrier film has the hole that average cell size is of about 1 micron；And matrix, this matrix has hole that average cell size is of about 10 microns, the filtration/conduit that backwashes, filtration/backwash outlet/import and for the installing hole/hub being arranged on filter plant by screen plate.Taking out and backwashing capacity according to filtrate, this structure has sufficient intensity and good flow performance.But, when condition is by such high-pressure peak, need that there is higher intensity and the structure of optimal flow performance.The flow design optimized is not had to make screen plate inside produce uneven pressure distribution.Design and be optimized to the situation when the structure of the backwash pressure of maximum 2 bar absolute pressures can not be used for producing pressure peak, but this pressure makes to produce the stress being high enough to make plate rupture in plate.
There is presently no international standard and the national sector standard of screen plate, the domestic industry standard only having filter, carry out the quality of specification screen plate.And the theoretical research aspect designed and developed of screen plate relatively lags behind so that the performance of screen plate and practical effect are difficult to meet the requirement that client is the highest, such as: the using effect of screen plate and service life.In the mine ore dressing technique in past using formula filtering techniques more, owing to this process energy consumption is big, yield poorly, water resource utility model is big, and mine tailing moisture is big, takes up an area wide, and causes and deposit potential safety hazard.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of Mechanical Method spray membrane process, the preparation of spray film adhesive: the weight ratio of each composition: zinc powder: clay: dolomite: potassium carbonate: carbon element: potassium humate=(0.30-0.40): (0.33-0.38): (0.0457-0.055): (0.22-0.25): (0.00047-0.0007)；Filming technology: with rotary mill, binding agent correct amount is positioned in pottery ball milling bottle, add 10kg rustless steel or glass bead or Midst density mill ball, add 5kg water, seal pin, side placing flat, ball milling opened pin after 24 hours, add white fused alumina abrasive micro-powder 10kg and 5-8kg water, after covering again ball milling 10 hours, cross 300 mesh sieves standby, add water as required when implementing spray film and carry out concentration of slurry adjustment, virgin pulp liquid: water=1: (0.1-0.2), spray film device is made up of air compressor machine and spray gun, and pressure is adjusted to 0.5MPa.
Barrier film and the matrix of the screen plate of the present invention are preferably manufactured from the same material, and only particle size is different.Barrier film and matrix can also be made from a different material.The screen plate of the present invention is preferably made up of at least one ceramic material, and such as aluminium oxide, carborundum, silicon dioxide, titanium dioxide, zirconium oxide and chromium oxide, they are sintered or glass is bonding.Other material such as graphite, amorphous carbon, sintering metal, plastics and cellulose can also use.And, the screen plate of the present invention can be used for conventional vacuum disc filters.
By adjusting the type selecting of the shape of substrate raw materials granularmetric composition and abrasive material, select high intensity, resistance to grinding, high rigidity and there is the abrasive material of high resistance to chemical attack carry out surface spray film and process, and optimize process combination further, make new product have: to improve the abrasion resistance of screen plate overall construction intensity and face；Improve the service life of screen plate；Product is raw materials used for inorganic solid overall, and without radiation toxic odor, sintering process uses natural gas to fire, and non smoke is discharged, without acid-alkali treatment and discharge in technique.
