Abstract
The utility model relates to an engineering machinery air inlet system prefilter, particularly to a solenoid valve controlled automatic dedusting prefilter. The prefilter comprises a housing, a prefilter lower cover and a solenoid valve controlled single-track dedusting device. A vortex tube upper separator plate and a vortex tube lower separator plate are disposed inside the housing. The two separator plates divide the housing into three independent chambers. A vortex tube is disposed inside the housing. One side of the housing is provided with the prefilter lower cover, and the other side of the housing is provided with an air outlet. The solenoid valve controlled single-track dedusting device is disposed on the prefilter lower cover. The solenoid valve controlled single-track dedusting device leads out an air source from an air storage tank air source, and the solenoid valve controls the air source to be connected or disconnected. The beneficial effects are that the solenoid valve controlled automatic dedusting prefilter adopts the above-mentioned arrangement to improve rough filtering efficiency of the prefilter, timely discharge the filtered dust, and achieve good usage effects in the actual loading usage process.
Description
Technical field
The utility model relates to a kind of engineering machinery gas handling system prefilter, particularly the automatic dust discharge prefilter of electromagnetic valve.
Background technique
At present, the problem that existing engineering machinery gas handling system prefilter mainly exists is: prefilter coarse filtration efficiency is low, causes air filter short maintenance period, and filter element life is short.And prefilter dust discharge weak effect is to cause the inefficient major reason of coarse filtration.On market, engineering machinery prefilter is mainly by following several mode dust discharges:
(1) dust-exhausting bag dust discharge.Dust-exhausting bag is installed on prefilter, but because the impulsive force that is subject to motor at prefilter weakens, dust-exhausting bag can not be effectively closed, dust can not be discharged in time, occurs fouling phenomenon, causes prefilter coarse filtration Efficiency Decreasing.
(2) utilize the dust discharge of muffler tail pipe injection.Prefilter uses injection dust discharge meeting to cause silencing apparatus exhaust back pressure to increase, and exhaust sound raises, and engine power reduces.Easily there is air refluence phenomenon in prefilter injection dust discharge simultaneously, coarse filtration reduces like this, and prefilter is impaired.
(3) straight-through cyclone tube type prefilter, utilizes tangential dust discharge.On prefilter, install fan additional, increase the tangential flow velocity of prefilter, dust is discharged from dust exhaust port, but the prefilter of this structure can not be realized this dust discharge effect on the market.Dust can not be discharged, and causes prefilter coarse filtration extremely low, and the dust being gone out directly enters again air filter inside.
Model utility content
The utility model, in order to make up the defect of prior art, provides a kind of overcome original prefilter coarse filtration Efficiency Decreasing and the impaired automatic dust discharge prefilter of electromagnetic valve of prefilter.
The utility model is achieved by the following technical solution:
The automatic dust discharge prefilter of electromagnetic valve, comprise housing, prefilter lower cover and the unidirectional dust exhaust of electromagnetic valve, cyclone tube upper clapboard and cyclone tube lower clapboard are installed in described housing, housing is divided into three independently spaces by two dividing plates, cyclone tube is installed simultaneously in housing, housing one side is equipped with prefilter lower cover, an other side is equipped with steam outlet pipe, under described prefilter, cover the unidirectional dust exhaust of electromagnetic valve is installed, the unidirectional dust exhaust of electromagnetic valve picks out source of the gas from gas holder source of the gas, by the switch of electromagnetic valve source of the gas.
Further, the unidirectional dust exhaust of described electromagnetic valve is made up of dust-exhausting bag and dust flue.
The beneficial effects of the utility model are: the automatic dust discharge prefilter of the utility model electromagnetic valve arranges by above, the utility model can improve prefilter coarse filtration efficiency, the dust being filtered off can be discharged in time, in actual entrucking using process, obtained good using effect simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the unidirectional dust outlet geometry schematic diagram of electromagnetic valve.
In figure, 1, suction tude, 2, housing, 3, steam outlet pipe, 4, cyclone tube upper clapboard, 5, cyclone tube, 6, cyclone tube lower clapboard, 7, cyclone tube baffle plate, 8, prefilter lower cover, 9, the unidirectional dust exhaust of electromagnetic valve, 10, dust-exhausting bag, 11, dust flue, 12, tracheae, 13, solenoid valve, 14, gas holder source of the gas.
Embodiment
Accompanying drawing 1-2 is a kind of specific embodiment of the present utility model.The automatic dust discharge prefilter of this model utility electromagnetic valve, comprise housing 2, the unidirectional dust exhaust 9 of prefilter lower cover 8 and electromagnetic valve, cyclone tube upper clapboard 4 and cyclone tube lower clapboard 6 are installed in described housing 2, housing 2 is divided into three independently spaces by two dividing plates, cyclone tube 5 is installed simultaneously in housing 2, housing 2 one sides are equipped with prefilter lower cover 8, an other side is equipped with steam outlet pipe 3, the unidirectional dust exhaust 9 of electromagnetic valve is installed on described prefilter lower cover 8, the unidirectional dust exhaust 9 of electromagnetic valve picks out source of the gas from gas holder source of the gas 14, controlled the switch of source of the gas by solenoid valve 13, the unidirectional dust exhaust 9 of described electromagnetic valve is made up of dust-exhausting bag 10 and dust flue 11.
The automatic dust discharge prefilter of this model utility electromagnetic valve, while opening solenoid valve 13 when use, gas enters dust flue 11 inside from tracheae 12, and from the dust exhaust port dust discharge prefilter assembly of dust flue 11, the now inner negative pressure value that produces of dust flue 11, dust-exhausting bag 10 is produced to outward expansion force, simultaneously, due to the getter action of prefilter, dust-exhausting bag 10 is also produced to inside tightening force, after solenoid valve 13 is opened, because dust-exhausting bag 10 is subject to the tightening force that outward expansion force that gas holder source of the gas 14 produces produces dust-exhausting bag 10 much larger than prefilter, dust-exhausting bag 10 is in open state, the dust being filtered off is so sucked out from dust-exhausting bag 10, discharge prefilter through dust flue 11, after solenoid valve 13 cuts out, dust-exhausting bag 10 is in closed condition.
The utility model is not limited to above-mentioned mode of execution, anyone should learn under enlightenment of the present utility model, make with the utlity model has identical or close technological scheme, within all falling into protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
