The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided one kind is simple in structure to be easy to
The fastening structure of oil mist separator in the vacuum pump of installation.
The purpose of this utility model can be realized by following technical proposal：The fastening of oil mist separator in a kind of vacuum pump
Structure, including separator, installing plate, supporting rack and snap ring, being horizontally disposed with the side wall of the separator has two positional structures
For the connector being distributed up and down, one is formed by welding between the connector and separator, it is equal at the connector
Straight coupling is provided with, the separator bottom is provided centrally with air inlet, shut-off valve is connected with the air inlet, its
It is characterized in that, the supporting rack is welded on installing plate by contiguous block makes between supporting rack and installing plate that there are gap, institute
The both ends difference bending for stating supporting rack forms card slot, and the wherein end face center of support frame as described above offers screw hole, other end
Edge had a groove, the inside bending in one end and the card slot of the snap ring cooperate, and the outside bending of the other end passes through nut
It is fixedly connected with screw hole.
Its technique effect of the fastening structure of oil mist separator is in this vacuum pump：The straight coupling of separator and vacuum pump
Exhaust pipe is connected, and the size of air inflow is controlled by shut-off valve, and separator is first positioned on supporting rack during installation, then passes through card
Ring one end is screwed by nut and supporting rack with the card slot clamping on supporting rack, the other end, separator is anchored on supporting rack,
It is installed in vacuum pump finally by installing plate, is welded to connect relative to traditional, passes through the fastening of supporting rack and snap ring
It is connected to install simpler and contribute to later stage detachable maintaining；The design of groove excessively can be such that snap ring is worn at mistake groove on supporting rack
Cross, increase the contact area of snap ring and separator, make its tightness more preferable, wherein support can be increased by the setting of contiguous block
Gap between frame and installing plate, when separator is squeezed, can prevent that separator is recessed by the elastic deformation of supporting rack
Fall into.
In a kind of above-mentioned vacuum pump in the fastening structure of oil mist separator, the upper and lower ends difference of the installing plate
Offer mounting hole.It can be facilitated by mounting hole and installing plate is installed on vacuum pump.
In a kind of above-mentioned vacuum pump in the fastening structure of oil mist separator, the position of the snap ring from two connectors it
Between pass through.The design of the structure can further prevent that snap ring absent-mindedness separator caused by takes off vacuum pump after long-term use
Fall.
In a kind of above-mentioned vacuum pump in the fastening structure of oil mist separator, the upper and lower ends of the separator are set respectively
It is equipped with anti-explosion set.The weld gas leakage of separator upper and lower ends can be prevented by explosion-proof Analysis of Nested Design.
In a kind of above-mentioned vacuum pump in the fastening structure of oil mist separator, the bending angle at support frame as described above both ends is
56 degree.
Compared with prior art, the phase interworking that the fastening structure of oil mist separator passes through supporting rack and snap ring in this vacuum pump
Conjunction is fixed to make it have and is easily installed and the advantages of later period maintenance.
