Abstract
The utility model relates to a vacuum device. A two-stage or more-stage steam jet vacuum pump is connected with two or more mechanical vacuum pumps through condensers. According to the vacuum device, the using amount of steam of the single steam jet vacuum device can be reduced, the carbon emission can be reduced, and the condensers can be arranged between the stages of the steam jet vacuum pump. According to the vacuum device, since two or more mechanical vacuum pumps are adopted, the number of opened mechanical pumps can be adjusted according to the sucking rate of a forepump, i.e., the efficiency is improved and the energy conservation effect is achieved.
Description
Technical field
The utility model relates to a kind of vacuum system, mainly in the mechanically supporting use of tobacco leaf processing.
Background technique
The vacuum system that uses on the tobacco leaf working machine mainly contains jet pump group, oil-sealed rotary pump group, single-stage vapor pump series connection separate unit oil-sealed rotary pump group mode now.
Ejector vacuum pump group device has characteristics such as the vacuum value of velocity of foundation is fast, equipment is simple, is to use at present maximum vacuum systems, but because burned coal price continuous rise in recent years, steam cost rises year by year, and burning of coal increases the carbon discharge capacity, is unfavorable for environmental protection.
One-level vapor pump and the vacuum system that oil-sealed rotary pump is formed, the degree of vacuum that reaches is lower, and the separate unit oil-sealed rotary pump speed of exhaust can not be regulated, and the mechanical pump design speed of exhaust is little, and manufacturing efficiency must be low; The speed of exhaust is big, because steam pump design rate of air sucked in required is little, oil-sealed rotary pump is obviously wasted energy consumption when opening vapor pump.The structural type equipment complexity that oil-sealed rotary pump cooperates with cooling machine set, maintenance difficult.
Summary of the invention
At the prior art deficiency, the utility model design secondary or the above steam jet vaccum of secondary and two or two above oil-sealed rotary pumps constitute jointly a kind of novel evacuated device.Between oil-sealed rotary pump and the steam jet vaccum condenser is set.The utility model has namely kept steam jet vaccum in the fast characteristics of high vacuum situation lower pumping speed, brought into play oil-sealed rotary pump again in the high characteristic of rough vacuum condition lower pumping speed, can regulate according to the needs of pump during many mechanical pump parallel operations and open the platform number, reach energy-efficient effect.
The utility model is to finish re-set target like this, and the utility model is to constitute jointly vacuum system by secondary or the above steam jet vaccum of secondary, condenser, two or many oil-sealed rotary pumps.
The utility model textural association is such.One-level steam jet vaccum vacuum orifice is connected with vacuum box, and exhaust port is connected with a condenser; Second steam ejector vacuum pump vacuum orifice is connected with first-stage condenser, and exhaust port is connected with No. two condensers; Second steam ejector vacuum pump vacuum orifice can be in series with condenser or prime steam jet vaccum.Steam jet vaccum can be made as one or more levels, and can connect also can be in parallel, and condenser can arrange one or more.Oil-sealed rotary pump is connected with steam jet vaccum by condenser, oil-sealed rotary pump platform number arranges more than two and (comprises two), divide main pump and service pump, when just opening oil-sealed rotary pump, except opening, main pump opens a mechanical pump at least again, two above mechanical pumps are worked simultaneously and can be strengthened rate of air sucked in required, make and taken out container (vacuum box etc.) and reach the degree of opening vapor pump rapidly, close the Aided Machine vacuum pump after opening vapor pump, the oil-sealed rotary pump main pump can vacuumize with prime vapor pump coupling.
The utility model compared with prior art has following advantage: the utility model adopts secondary or the above vapor pump of secondary and two or two above oil-sealed rotary pumps composition vacuum systems.This device can guarantee under high vacuum condition, and the advantage that the speed of exhaust is fast again can be under the rough vacuum condition, and the high characteristics of the speed of exhaust of performance oil-sealed rotary pump reach energy-efficient effect.This device obviously strengthens the speed of exhaust of mechanical pump when just vacuumizing, the time that the initial stage that shortened vacuumizes, can bring into play the characteristic of big rate of air sucked in required under its high vacuum condition after steam jet vaccum is opened.Both have reduced the big drawback of vapor pump power consumption again in conjunction with obviously improving the efficient of finding time, and the carbon discharge capacity has obtained effective control.
Below in conjunction with drawings and Examples the utility model is described in detail.
