Abstract
The utility model provides a movable exhaust emission device for a mechanical pump of a scanning electron microscope. An exhaust emission device body is disposed on a pedestal and comprises PVC plastic covers, a movable baffle plate, a slot, an exhaust fan and a plastic hose, wherein the baffle plate is capable of moving in the slot for adapting to sizes of different vacuum mechanical pumps; the exhaust fan is disposed right in the middle of the top of the mechanical pump cover; and the pedestal is fixed on universal wheels. The movable exhaust emission device occupies less space, enables the dimensions to be adjusted, is easy to move, and is low in cost. The movable exhaust emission device is capable exhausting harmful gas out of a lab and protecting health of personnel in the lab.
Description
Technical field:
The utility model relates to a kind of removable SEM mechanical pump exhaust emission device, relates in particular to a kind of vacuum mechanical pump toxic emission and laboratory safety field.
Background technology:
When SEM was worked, the vacuum mechanical pump of ESEM was in running order always, guaranteed the vacuum in the sample room.Yet the waste gas that the vavuum pump of most of ESEM is extracted out be simple filter element filtering with regard to outside the excavationg pump, be diffused in the laboratory harm health of operators.If but use large-scale ventilating fan to bring very large influence to the constant temperature in the laboratory, constant humidity.So we have invented small-sized removable SEM mechanical pump unit of exhausting waste gas and have solved this problem.
Summary of the invention:
The purpose of the utility model; It is exactly defective to existing SEM mechanical pump equipment; And provide a kind of removable SEM mechanical pump special-purpose unit of exhausting waste gas, and not only simple in structure, the conveniently moving of this device, and with low cost, practical.
The technical scheme that the utility model technical solution problem is adopted is: removable SEM mechanical pump exhaust emission device; It is characterized in that: exhaust emission device is arranged on the base, and exhaust emission device is made up of PVC plastics cover body, sideboard, slot, air exhauster, plastic flexible pipe; Wherein, sideboard can move in slot, adapts to the size of different vacuum mechanical pumps; Small-sized air exhauster is arranged on directly over the cover body, improves the effect of exhaust; Base is fixed on the universal wheel, and base can freedom and flexibility be moved.Have two holes on the sideboard, the filter core of mechanical pump is passed through.
The beneficial effect of the utility model is: this device has little, the adjustable size of taking up room, conveniently moving, advantage such as with low cost.This device can in time be discharged the laboratory to harmful exhaust, ensures the health of lab assistant.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is plastic flexible pipe, and 2 is the air exhauster cover body, and 3 is the mechanical pump cover body, and 4 is slot, and 5 is base, and 6 is universal wheel, and 7 is sideboard.
The specific embodiment:
As shown in the figure, the utility model comprises: devices such as plastic flexible pipe, air exhauster cover body, mechanical pump cover body, slot, base, universal wheel, sideboard.The mechanical pump cover body places on the base, and base is fluted to prevent the displacement of mechanical pump cover body, and four universal wheels are connected on the base through alignment pin, and the mechanical pump cover body can arbitrarily move through base.Center evolution mouth, mechanical pump cover body can be positioned over ESEM mechanical pump top.Mechanical pump cover body top is provided with air exhauster, and leaves aperture plastic flexible pipe is set, and the plastic flexible pipe end places outdoor.The air exhauster power supply is connected with mechanical pump, is starting mechanical pump moment unlatching air exhauster.
