Abstract
The invention provides an exhaust ejection dust extractor which comprises a spray pipe, a dust extraction chamber and a mixing chamber, wherein waste gas of an engine is sprayed into the mixing chamber from the spray pipe so as to form a certain vacuum degree in the dust extraction chamber, and the exhaust ejection dust extractor is characterized by further comprising an exhaust branch pipe communicated with the spray pipe before the mixing chamber; and a valve for controlling the flow rate of air in the exhaust branch pipe is mounted on the exhaust branch pipe. Experiments of the exhaust ejection dust extractor provided by the invention show that, dust exhaust of an automobile can meet the requirements of different environments on the dust extraction capability of the dust extractor by controlling the valve mounted on the exhaust branch pipe. Therefore, the device can regulate the dust extraction effect according to the dust content in the environment and simultaneously reduce the exhaust resistance and the power consumption of the engine.
Description
Technical field
The present invention relates to the air-strainer dust discharge in the vehicle exhaust system, specifically is that a kind of exhaust injection is taken out the dirt device.
Background technique
The characteristics that the exhaust injection that at present is used for automobile is taken out the dirt device are that engine speed is higher, and load is bigger, and it is bigger to take out in the dirt chamber degree of vacuum, and it is effective to take out dirt.Otherwise when engine speed reduced, degree of vacuum reduced, and took out the dirt effect and reduced.Exhaust injection is taken out the simple in structure of dirt device, reliable performance, but exhaust resistance is increased, the power of consumption of engine is bigger.To high blower engine, too high because of exhaust back pressure, cause turbosupercharger overheated easily.
The patent of invention content
Increase for overcoming the exhaust resistance that exists in the existing technology, the power of consumption of engine is bigger, and is too high because of exhaust back pressure to high blower engine, causes overheated deficiency easily, the present invention proposes a kind of bypassing exhaust formula exhaust injection and take out the dirt device.This exhaust injection is taken out the dirt device through increasing by an exhaust branch pipe at the nozzle entry place; And a gas control dish valve is installed on the arm; Through the leading to, close and realize controlling exhaust gas flow of control gas control dish valve through jet pipe, make that to take out in the dirt chamber degree of vacuum adjustable, thereby can being regulated according to the content of dust in the environment, this device takes out the dirt effect; Reduced the engine exhaust resistance simultaneously, and power consumpiton.
For realizing above-mentioned purpose; The invention provides a kind of exhaust injection and take out the dirt device; Comprise jet pipe, take out dirt chamber and mixing chamber, engine exhaust sprays into mixing chamber from said jet pipe, makes to take out the certain degree of vacuum of the indoor formation of dirt; It is characterized in that, also comprise: the exhaust branch pipe that is connected before the mixing chamber with said jet pipe; The valve of air mass flow in the control exhaust branch pipe is installed in the said exhaust branch pipe.
Wherein, said exhaust branch pipe preferably should be connected with jet pipe before the convergence of the cross section of said jet pipe.
Wherein, said valve is the various valves that can control air mass flow in the said exhaust branch pipe, reaches the Kai Heguan that can control the exhaust branch pipe pipeline at least, and existing gas control butterfly valve, ball valve etc. all can be selected for use.
Dust discharge of the present invention is achieved in that the needs according to environment and dust discharge; Control air mass flow through the bronchus road (valve can be at complete shut-down, close between change continuously or discontinuously) through being installed in valve on the exhaust branch pipe; Thereby control the waste gas content that from jet pipe, sprays in the mixing chamber indirectly, reach and regulate the purpose of taking out the indoor degree of vacuum of dirt.
Use the automobile of apparatus of the present invention, can be installed in the control of the valve on the exhaust branch pipe, make the automobile dust discharge satisfy varying environment and take out the requirement of dirt ability taking out the dirt device through control.Thereby device can be regulated according to the content of dust in the environment take out the dirt effect, reduced engine exhaust resistance and power consumpiton simultaneously.
Description of drawings
Do further explain below in conjunction with accompanying drawing and mode of execution of the present invention.
Fig. 1 takes out dirt device schematic representation for exhaust injection; Wherein:
1. jet pipe 2. is taken out dirt chamber 3. mixing chambers, 4. diffusing tubes
5. tailpipe 6. gas control dish valves 7. exhaust branch pipes
Embodiment
As shown in Figure 1, exhaust injection takes out that the dirt device generally comprises that the jet pipe 1 that links to each other with the engine exhaust system (not shown) links to each other with the dust collecting box (not shown) takes out dirt chamber 2, mixing chamber 3 and diffusing tube 4.The waste gas of discharging from motor is during through jet pipe 1, and because of restraining gradually in the cross section of jet pipe 1, waste gas quickens to flow in jet pipe, sprays into the mixing chamber 3 from jet pipe 1, shown in arrow a, takes away taking out dirt chamber 2 interior air, forms certain degree of vacuum.Degree of vacuum in taking out dirt chamber 2 is during greater than the degree of vacuum in the dust collecting box, and dust in the dust collecting box and air are inhaled into together takes out dirt chamber 2, shown in arrow b, and then takes out of outside the car with waste gas.
And in the present invention, the preferred embodiment that exhaust injection is taken out the dirt device also is included in the exhaust branch pipe 7 that links to each other with jet pipe 1 before the cross section convergence of jet pipe 1.Gas control butterfly valve 6 is installed in the exhaust branch pipe 7, is used to control air mass flow through exhaust branch pipe.The concrete size of the bore of exhaust branch pipe 7 should guarantee that when valve wide open empty filter is taken out dirt pipe inlet pressure greater than outlet pressure, guarantees to take out the interior gas of dirt pipe and can not flow backwards.Exhaust branch pipe 7 afterbodys also are connected with the tailpipe 5 that spreads gradually in the cross section.Gas control dish valve 6 can use commercially available various products, as the one of which by the push buttonvalve control open and close that is installed in the operator cabin.In amount of dust few or other need not take out under the situation of dirt, close gas control butterfly valve 6, the passages in the exhaust branch pipe 7 are opened, the waste gas that flows out from motor before getting into mixing chamber 3 just part get into exhaust branch pipe 7 (shown in arrow c), discharge from tailpipe 5.Thus, significantly reduce owing to spray into the air of mixing chamber 3, the degree of vacuum of then taking out dirt chamber 2 reduces greatly, thereby has reduced the exhaust resistance and the power consumpiton of motor, and the dangerous situation generation of also having avoided turbosupercharger overheated under the situation of turbosupercharger is being arranged.And in amount of dust big or other need take out under the situation of dirt, can open gas control butterfly valve 6, exhaust injection is taken out the dirt device just can normally take out dirt.
Wherein, jet pipe 1 can be connected as a single entity through welding with exhaust branch pipe 7.Tailpipe 5 can be installed as required.In the middle of other embodiments of the present invention, gas control butterfly valve 6 can also be replaced by the switching that ball valve is controlled exhaust branch pipe 7.
