Utility model content
For the above problem above, the utility model provides a kind of environmentally friendly nothing easy to use, operation is convenient, powerful
Oily vertical piston vacuum pump.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:, and a kind of environmental protection is oil-free vertical reciprocal
Vacuum pump, including pedestal, fuselage and motor are installed on the pedestal, and the motor is installed on the fuselage by belt transmission
The belt pulley of side, the inside of the fuselage are equipped with crankshaft, connecting rod are connected on the crankshaft, in the junction of crankshaft-and-connecting-rod
Equipped with connecting rod bearing shell, the top of the connecting rod connects crosshead by crosshead pin, and the crosshead is solid by locking nut
Surely piston rod is connected, the fuselage roof is fixedly connected with cylinder, and the inside in cylinder is fixedly installed piston, the gas
The top of cylinder is by screw connection cylinder head, and in the air-valve assembly that is internally provided with of cylinder head, fuselage roof two sides are respectively equipped with
The air inlet and exhaust outlet connecting with air-valve assembly, the air inlet are equipped with dust-filtering chamber, and dust-filtering chamber side connects
It connects the air inlet other side and connects the air-valve assembly, the intracavitary portion of dust-filtering is equipped with dust filtering device.
Further, the dust filtering device is electrostatic electret capacitance strainer, and the dust-filtering is intracavitary to be equipped with fixed strainer
Sliding slot.
Further, dust-filtering top of chamber is equipped with cover board, and the cover board and cavity junction are equipped with sealing ring.
Compared with prior art, the utility model has the beneficial effects that by one end stretching of crankshaft and fuselage, for filling
Belt pulley, connecting rod connect crankshaft and crosshead, and the lower end of piston rod screws in crosshead and screw hole, thus constitute
Interlinked mechanism moves back and forth the rotation motion of crankshaft in the cylinder at piston since connecting rod and crosshead act on, thus real
It is now evacuated purpose, then respectively has an air cavity by the symmetrical two sides of cylinder, passes through air inlet pipe and the appearance for needing to vacuumize
Device connection, through the intracavitary electrostatic electret capacitance strainer filtering of dust-filtering, will have dirt gas absorption, enters back into air cavity, such as encounter
Operating environment can be taken away strainer by cover board without more dust, be directly entered in air cavity, then by discharge chamber through exhaust pipe
Lead to outdoor discharge.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is the utility model side structure schematic view.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
According to Fig. 1-2, the utility model provides a kind of technical solution: a kind of environmental protection vertical unoiled reciprocal vacuum pump,
Including pedestal 1, fixed organic 2 body and motor 3 on the pedestal 1, the motor 3 are installed on the fuselage 2 by the transmission of belt 4
The belt pulley 21 of side, the inside of the fuselage 2 are equipped with crankshaft, connecting rod are connected on the crankshaft, in the company of crankshaft-and-connecting-rod
It meets place and is equipped with connecting rod bearing shell, the top of the connecting rod connects crosshead by crosshead pin, and the crosshead passes through locking screw
Mother is fixedly connected with piston rod, and the fuselage roof is fixedly connected with cylinder, and the inside in cylinder is fixedly installed piston, institute
The top of cylinder is stated by screw connection cylinder head, in the air-valve assembly that is internally provided with of cylinder head, fuselage roof two sides difference
Equipped with the air inlet 22 and exhaust outlet 23 connecting with air-valve assembly, the air inlet 22 is equipped with dust-filtering chamber 25, the dust
