Description
Technical field
The utility model relates to a kind of vertical centrifugal machine with liquid sealing device.
Background technology
Centrifuge is that the centrifugal inertial force that utilizes drum rotating to produce is realized the separation of suspension, emulsion and other heterogeneous material or concentrated machine.
Centrifuge divides by separation principle, mainly contains two kinds of unpack formats of filtering type and decanter type; Divide by solid phase discharging form, can be divided into gravity dumping, artificial top discharging, manually descend the types such as discharging, centrifugal discharge, scraper discharging, vacuum intake and screw unloading, the utility model only relates to vertical loading and unloading material centrifuge, comprise the flat artificial top discharging centrifuge of SS 3-foot and PS, and SD 3-foot and the flat artificial hanging bag type loading and unloading material centrifuge of PD.
3-foot is relative simple with flat loading and unloading material centrifuge structure; applicability to material is strong; it is the widest perforated wall centrifuge of application surface; primary structure and operation principle are: rotary drum is fixed on the main shaft of bearing block support; be rotated through the belt transmission main shaft by motor; be drilled with aperture on the bulging wall in the rotary drum; the included one deck filter cloth of drum wall; when material enters the rotary drum of rotation; solid phase is blocked in the filter cloth in the rotary drum; liquid phase then is thrown in the casing through filter cloth and the annular collecting tank leakage fluid dram in support flows out, and after the shutdown solid phase is drawn off and namely finishes the whole course of work.
Consider the combination property of metal material, the main shaft of centrifuge is general mainly to be made by No. 45 steel or 40Cr steel, mechanical performance is good, cheap, traditional first-selected steel of axle class, but these steel have fatal shortcoming, are exactly that anti-corrosion capability is poor, in order to prevent that corrosive liquids in the material is to the etch of main shaft, can adopt some maze-type structures to intercept, can play certain effect, but for the material that the volatility etchant gas is arranged, the corrosion-resistant difficulty is just larger, because processing has the centrifuge of volatile material generally all to require closed-loop operation, so be full of corrosive gas in centrifuge inside, maximum to the main shaft infringement, at first main harm is that corrosion causes the main shaft rough surface, the wearing and tearing oil sealing, cause corrosive liquids to enter bearing block, cause bearing corrosion, it is dangerous that centrifuge is produced; Next is that corrosion to main shaft may cause main shaft in use to split off, and produces major accident.
In sum, the volatility etchant gas is very obvious to the harm of centrifuge principal axis, so need the sealing device of a kind of safety, energy-conserving and environment-protective to improve the security of centrifuge principal axis, improves the Integrated using effect of centrifuge.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art; a kind of vertical centrifugal machine with liquid sealing device is provided; by between rotary drum and bearing block, gas-tight silo being set; pumping liquid in the gas-tight silo; so that centrifuge can both make the etchant gas isolation in main shaft and the rotary drum when starting and stopping, reaching the effect of seal protection.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of vertical centrifugal machine with liquid sealing device, it comprises base, be fixed on bearing block on the base, be connected with bearing block and by motor-driven main shaft be installed in rotary drum on the main shaft, between rotary drum and bearing block, be provided with sealing device, the sealing device comprises the gas-tight silo that is arranged between rotary drum and the bearing block, is arranged in gas-tight silo below and the water storage storehouse that is connected with gas-tight silo, is used for the pump of the liquid suction gas-tight silo in water storage storehouse, the pump motor of driving pump running are connected with the liquid discharge pipe of liquid in the discharging gas-tight silo on the gas-tight silo.
Preferably, the outlet of gas-tight silo discharge liquid is higher than the bottom surface of gas-tight silo, can make sealing device keep sealing when shutting down.
Preferably, gas-tight silo is labyrinth structure, can make sealing device keep airtight under rotation status.
Further preferably, liquid discharge pipe is connected to the bottom of described labyrinth structure, can regularly replace the water of the gas dissolution that is corroded, and keeps sealing device effectively to move.。
According to a preferred aspect of the present utility model, gas-tight silo is connected by feed tube with pump, and the water storage storehouse is connected by a pipeline with pump.
The utility model compared with prior art has following advantage:
The utility model is in the application of multiple vertical upper unloading centrifuge; especially in the feed separation that has the volatility etchant gas to exist is used; by between rotary drum and bearing block, gas-tight silo being set; pumping liquid in the gas-tight silo; so that no matter centrifuge is to start or shutdown; can realize protecting the function of centrifuge principal axis, can also regularly change sealing water simultaneously, use cost is cheap.
