Abstract
The invention discloses a multi-layer coal water slurry and powdered coal screening device with different screen holes and aims to provide a device capable of screening the coal water slurry and the powdered coal into different particle size range at one time. The multi-layer coal water slurry and powdered coal screening device comprises an adjustable valve implementing unit, a sprinkler, special test sieves (with annular metal plates and rubber pads at the bottom) with different screen holes, device inner-wall rubber pads, a bottom vibrator, a drain pipe, a flow meter (with a time delay switched and a device door with a handle. The test sieves are arranged in the device from top to bottom as the screen holes from large to small, the sprinkler on the upper portion can control water flow via the adjustable valve implementing unit, the bottom vibrator can vibrate the test sieves, and the coal water slurry and the powdered coal can be sequentially screened by the test sieves as the hole diameter gradually decreases layer by layer. The multi-layer coal water slurry and powdered coal screening device solves the problem that an existing coal water slurry and powdered coal screening and testing method has to use the test sieves having different sizes of the screen holes and time and energy are wasted due to the fact that manpower is required to place the test sieves into a water basin to be shaken or flushed by the water flow. The multi-layer coal water slurry and powdered coal screening device is applicable to screening of the coal water slurry and the powdered coal.
Description
Technical field
The present invention relates to screening plant, more particularly a kind of multilayer water coal slurry, coal powder sieve equipment with different sieve aperture, the testing sieve that water-coal-slurry, fine coal sample successively reduce through aperture sieves successively, screen cloth is less than the coal grain of screen size successively through different pore size screen cloth, disposable is the equipment of different particle size range by water-coal-slurry, coal powder sieve.
Background technology
Current water-coal-slurry, coal powder sieve test method successively use the testing sieve of different screen size, artificial basin of being put into by testing sieve rocks or sieves with the online water-coal-slurry of slow-flowing stream washing screen, fine coal sample, at substantial time, manpower, and unclean.Be necessary to invent multilayer water coal slurry, the coal powder sieve equipment with different sieve aperture for this reason, traditional successively screening be improved to disposable screening, fast save time, save manpower, and more clean.
Summary of the invention
The object of this invention is to provide a kind of multilayer water coal slurry, the coal powder sieve equipment with different sieve aperture, can be different-grain diameter scope by water-coal-slurry, the disposable screening of fine coal.
Object of the present invention realizes in the following manner: have the multilayer water coal slurry of different sieve aperture, coal powder sieve equipment, comprise adjustable valve performance element, gondola water faucet, the testing sieve (bottom belt annular metal sheet and rubber sheet gasket) of special different sieve aperture, equipment inner wall rubber sheet gasket, vibrating bottom device, drainpipe, flowmeter (band delay switch), is with handled appliance doors.It is characterized in that: equipment has multilayer bracket, special sieve aperture testing sieve puts into equipment from top to bottom by sieve aperture is descending; Each Special test sieve bottom periphery has annular metal sheet, can prop up and be put on equipment supporter; Equipment inner wall has rubber sheet gasket, strengthens effect of vibration to make equipment and testing sieve strong bonded; Device bottom has vibrating device.During screening, water-coal-slurry, fine coal are added by ground floor testing sieve, start screening plant, gondola water faucet with initial flow rate to be sized water-coal-slurry, fine coal spray, device bottom vibrating device drives each testing sieve to vibrate simultaneously, promotion water-coal-slurry, fine coal sieve through each layer compass screen surface, and waste water discharges from device bottom drainpipe.If flowmeter detects that discharge is less than setting safety value, automatic Control Systems of Liquids Height can feed back to adjustable valve, reduces gondola water faucet flow.After screening terminates, each testing sieve can be taken out by the appliance doors that can open.Coal grain on each compass screen surface is collected and puts into measuring cup weighed in advance, weigher quality after oven for drying, the quality of coal grain in particle size range between adjacent two sieves can be calculated, and and then calculate the mass fraction that this particle size range coal grain accounts for water-coal-slurry, fine coal.
The present invention has the following advantages compared with existing water-coal-slurry, coal powder sieve technology: traditional successively manually adding water with different pore size testing sieve sieved, be improved to disposable screening, fast save time and save manpower; Top gondola water faucet automatic watering and removing from manually adds water; There is vibrating device bottom and removes from and manually rock testing sieve; Testing sieve aspect ratio common standard sieve is high, avoids water-coal-slurry, fine coal liquid to flow out from sieve basket top; More more clean than traditional coal-water-slurry, coal powder sieve method.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Detailed description of the invention
As follows with reference to accompanying drawing, there is the multilayer water coal slurry of different sieve aperture, coal powder sieve equipment, comprise adjustable valve performance element 1, gondola water faucet 2, the testing sieve (bottom belt annular metal sheet and rubber sheet gasket) 3 of special different sieve aperture, equipment inner wall rubber sheet gasket 4, vibrating bottom device 5, drainpipe 6, flowmeter (band delay switch) 7, is with handled appliance doors 8.
It is characterized in that: the special testing sieve (bottom belt annular metal sheet and rubber sheet gasket) 3 with different sieve aperture, base circle metallic plate can prop up and be put on equipment supporter, bottom rubber sheet gasket makes upper strata testing sieve and lower floor's testing sieve seal to prevent sample from oozing out, testing sieve will put into equipment from top to bottom by sieve aperture is descending, open the gondola water faucet 2 of its upper side and regulate adjustable valve performance element 1 flow to make sluggish flow, equipment inner wall rubber sheet gasket 4 makes equipment and testing sieve combine closely.Device bottom vibrating device 5 can make each testing sieve vibrate, and can promote that water-coal-slurry, fine coal sieve through each layer compass screen surface.The time delay of flowmeter (band delay switch) 7 goes into operation in the initial action of gondola water faucet water spray, if flowmeter 7(is with delay switch) record drainpipe flow and be less than flow of inlet water, start automatic Control Systems of Liquids Height, feed back to adjustable valve, reduce gondola water faucet flow, screening waste water discharges from device bottom drainpipe 6.After screening terminates, open the handled appliance doors 8 of band and each testing sieve is taken out.
