Description
Technical field
This device relates to a kind of roots blower emptying, the effective ways of stress release treatment and the design field of minimizing cost.
Background technique
Current roots blower is a kind of high pressure positive blower, and roots blower is volume rotary blower, utilizes two lobed rotor compress do relative movement in cylinder and carry the rotary compressor of gas.This compressor makes two rotors keep engagement by the synchromesh gear of rotor axle head.On rotor, each recessed curvature portion and cylinder inner wall form swept volume, gas is taken away from intakeport in rotor turning course, when moving on to be connected with relief opening near relief opening instantaneous, because there being the gas backstreaming of elevated pressures, at this moment the pressure in roots blower swept volume raises suddenly, then delivers gas to exhaust passage.Because its structure is simple, smooth running, stable performance, is suitable for multiple use, is widely used in a lot of fields.But because roots blower is periodically inhaled, is vented and instantaneous etc. holds the pulsation that compression causes airspeed and pressure, thus larger aerodynamic noise can be produced.In addition, Leakage Gas can be caused in the gap between rotor and between rotor and cylinder, thus efficiency is reduced.
Model utility content
The utility model object is for above problem, there is provided a kind of roots blower in the past that solves need lay the way that long spool pass extends outside room and minimizing fixes a silencer, and be roots blower emptying and the stress release treatment device of kinetic energy by part emptying potential energy.
The utility model comprises air intake pipe, fan body, air outlet tube, bypass airduct, emptying airduct; One end of described air intake pipe and the connection of fan body, arrange the first silencing apparatus at the other end of described air intake pipe; The output terminal of described fan body connects the input end of air outlet tube, sets gradually the second silencing apparatus, the second butterfly valve on described air outlet tube, along air-out direction; Connecting bypass airduct on air outlet tube between described fan body and the second silencing apparatus, the output terminal of described bypass airduct connects emptying airduct by the first butterfly valve, and the output terminal of described emptying airduct is connected on air intake pipe; Described fan body connects motor.
Bypass line on roots blower delivery line is added regulating butterfly valve by the utility model, and by pipeline other end access air inlet pipeline, set bypass line is identical with blowdown piping bore, makes it to be in operation the optimum state by inflation blast, air quantity at the bottom of regulating butterfly valve regulation warehouse.Make the blast of blowdown piping and air intake airduct conflux in roots blower simultaneously, thus be kinetic energy by potential energy.The utility model solves roots blower in the past need lay the way that long spool pass extends outside room and minimizing fixes a silencer, and is kinetic energy by part emptying potential energy.
Emptying airduct described in the utility model, air intake pipe, air outlet tube are identical with the bore of bypass airduct.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises air intake pipe 1, fan body 2, air outlet tube 3, bypass airduct 4, emptying airduct 5, and emptying airduct 5, air intake pipe 1, air outlet tube 3 are identical with the bore of bypass airduct 4; One end of air intake pipe 1 and the connection of fan body 2, arrange the first silencing apparatus 6 at the other end of air intake pipe 1; The output terminal of fan body 2 connects the input end of air outlet tube 3, sets gradually the second silencing apparatus 7, second butterfly valve 8 on air outlet tube 3, along air-out direction; Connecting bypass airduct 4 on air outlet tube 3 between fan body 2 and the second silencing apparatus 7, the output terminal of bypass airduct 4 connects emptying airduct 5 by the first butterfly valve 9, and the output terminal of emptying airduct 5 is connected on air intake pipe 1, and described fan body 2 connects motor 10.
