Description
Technical field
The utility model relates to technical field of chemical, relates in particular to a kind of vacuum rake style drier.
Background technology
Drier is by heating, the vaporization of hygroscopic water (referring generally to moisture or other volatile liquid components) in material to be overflowed, to obtain the plant equipment of solid material of regulation moisture content.Dry run need to consume a large amount of heat energy, and in order to save energy, the material that some moisture content is high, the suspension that contains solid matter or solution are general first through mechanical dehydration or heating evaporation, then at drier inner drying, to obtain dry solid.
Anti abrasive rake type dryer is a kind of novel horizontal intermittent vacuum drying equipment, and wet stock, through conduction evaporation, is constantly removed the material on hot side with scraper plate agitator, and passes and form circular flow in container, after water evaporates, is extracted out by vavuum pump.Anti abrasive rake type dryer, uses morely in the organic semi-finished product in chemical industry and fuel drying process.
Anti abrasive rake type dryer has simple in structure, easy to operate, life cycle is long, stable and reliable for performance, steam consumption quantity is little, and applicable performance is strong, good product quality, be specially adapted to the dry of plaster material oxidizable under non-refractory, inflammable, temperature adjustment, this machine proves a good drying equipment through long-term use of user.
Steam jacket indirect material for anti abrasive rake type dryer device, and exhaust under high vacuum, therefore adapt to especially non-refractory, be at high temperature easy to the material of oxidation or easily produce the material (as various fuel) of powder when dry, and the dry materials operation that must reclaim of the steam of getting rid of in dry run or solvent.The material that is dried adds from middle, housing top, under the stirring of the rake teeth constantly rotating, when material contacts with housing wall, surface is constantly updated, and the material that is dried is subject to steam indirect, and material moisture is gasified, the moisture of gasification is taken away in time by vavuum pump, and this machine can adopt interlayer and rake teeth mode of heating simultaneously simultaneously, and heat transfer area is larger, the thermal efficiency is high, makes it obtain higher drying efficiency.Because operation vacuum is higher, the water vapour pressure of material surface water vapour pressure much larger than evaporating space in dryer shell is dried, thereby the discharge of be conducive to be dried material internal moisture and surface moisture, the hydrone motion of the material that is conducive to be dried, reaches drying purpose.
In existing rake type dryer, the valve seal of its bottom is engaged in the outer surface of drier, falls into the material at drier discharging opening place, and the rake teeth that can not be dried in device drives, and rate of drying is slower, thereby affects the dry mass of material.
Utility model content
For overcoming the defect existing in prior art, the utility model provide a kind of rational in infrastructure, simple to operate and be convenient to processing vacuum rake style drier, this drier having is useful on the lifting valve of shutoff discharging opening, and the end face that lifting valve is set is the cambered surface adapting with drier inwall, inwall after drier sealing, on same side face, makes dry materials more abundant.
A kind of vacuum rake style drier, comprise that bottom is provided with the housing of discharging opening, the discharge bin being communicated with discharging opening, described discharge bin is provided with the lifting valve coordinating with discharging opening, described lifting valve comprises lifter plate, lifter plate top convexes with the boss coordinating with discharging opening, and the end face of described boss is the cambered surface adapting with inner walls, and the lifter plate end face that is positioned at described boss surrounding is fixed with sealing gasket.
After dry materials in housing completes, drive lifting valve to decline, material is entered in discharge bin by discharging opening, completes the discharge of material in housing.Existing valve coordinates and seals discharging opening with housing outer wall, and the problem of its existence is: after discharging opening sealing, material also can enter in the groove of discharging opening formation, and when dry, this part material is difficult to be driven by rake teeth, and rate of drying is slower.
For addressing the above problem, lifting valve of the present utility model comprises lifter plate, and the top at lifter plate is provided with boss, this boss end face has the cambered surface adapting with inner walls, after discharging opening is sealed by lifter plate, boss stretches in discharging opening, and boss end face and inner walls are on same side face, the material of housing bottom all can be driven by rake teeth, accelerate the rate of drying of material.
Meanwhile, the plate top surface of boss surrounding is fixed with sealing gasket, and sealing spacer has resistant to elevated temperatures characteristic, and sealing gasket coordinates with housing outer wall, to keep the sealing at discharging opening place.
As preferably, described discharge bin has the base plate of inclination, and the lowest part of described base plate is provided with feed opening.
Because discharge bin has the bottom of inclination, the material in discharge bin moves and is discharged by the feed opening of lowest part along base plate, can prevent the accumulation of material in discharge bin.
As preferably, described feed opening place is provided with dust gathering arrester.
For the dry particulate dust obtaining, while discharge by feed opening, easily diffuse in air, be therefore provided with dust gathering arrester at feed opening place, can limit the diffusion of particulate dust.
As preferably, also comprise the valve rod that drives described lifting valve, described base plate bottom is connected with tapped sleeve, and described valve rod coordinates with bush whorl and passes described base plate, and the top of valve rod is fixedly connected with lifter plate.
Lifting valve is by the valve rod control through discharge bin base plate, and this lifting valve coordinates with the bush whorl of connecting bottom board, is convenient to lock lifting valve, and stem bottom is provided with the rotating disk of being convenient to rotation.
As preferably, described discharge bin is provided with access hole, and is provided with the hermatic door coordinating with access hole by opening soon flange, and a side of discharge bin is also provided with transparent window.
Transparent window is for observing the situation in discharge bin, and whether need discharge bin clear up, can repair lifting valve and the valve rod in discharge bin by access hole if can determine, also can clear up the material remaining in discharge bin.
As preferably, the cross section of described boss is trapezoidal, and cross section is that trapezoidal boss is larger with the area that discharging opening edge contacts, and can promote the sealing effectiveness of lifting valve.
The utility model is rational in infrastructure, simple to operate, and is convenient to processing; This drier having is useful on the lifting valve of shutoff discharging opening, and the end face that lifting valve is set is the cambered surface adapting with drier inwall, and the inwall after discharging opening sealing, on same side face, makes dry materials more abundant.
