Abstract
The invention discloses a tight anti-explosion horizontal centrifuge which can prevent gas in an inner chamber of a shell from leaking outwards. The tight anti-explosion horizontal centrifuge comprises an engine base which is movably provided with a barrate, wherein a shell covers outside the barrate; an intake joint penetrates through on the shell; intake devices for preventing leakage of gas between the shell and the barrate are respectively arranged at the left and right ends of the barrate; and an intake device for preventing leakage of gas between a sleeve and the barrate is arranged at the left side of the barrate. In the invention, the corresponding rotating shaft is provided with two sealing rings between which an intake passage is arranged. During the operation of the centrifuge, air pressure in the intake passage is ensured to be higher than that in the inner chamber of the shell, thereby effectively ensuring that gas in the inner chamber of the shell can not be leaked into air around and avoiding damage to operators by toxic gas.
Description
Technical field
The present invention relates to horizontal centrifuge, refer more particularly to tight anti-explosion horizontal centrifuge.
Background technology
In some special industries such as chemical industry, pharmacy and power plant, can not under the environment of aerobic, separate feed liquid.During use, at first to the air displacement in the chassis cavity be fallen with inert gas, and continuous topping up in chassis cavity at work, guarantee the air pressure in the chassis cavity, prevent that the air of outside from entering into chassis cavity.Just since the air pressure in the chassis cavity than outside height, the gas leakage that has toxicity that evaporates in the feed liquid separation process damages operating personnel's human body in ambient air.
Summary of the invention
Technical problem to be solved by this invention is: can prevent the tight anti-explosion horizontal centrifuge that the gas in the chassis cavity is outwards revealed.
For solving the problems of the technologies described above, the technical solution used in the present invention is: tight anti-explosion horizontal centrifuge, comprise: support, be movably set with rotary drum on the support, the outer mask of rotary drum has casing, be equipped with inlet suction port on the described casing, the left and right end of described rotary drum is respectively arranged with the inlet duct that prevents the gas leak between casing and the rotary drum, and the left side of described rotary drum also is provided with the inlet duct that prevents gas leak between sleeve pipe and the rotary drum.
Described inlet duct comprises: seal receptacle, offer two annular seal grooves and the annular air inlet duct between two annular seal grooves on the inwall of seal receptacle, also offer the inlet channel that communicates with annular air inlet duct in the seal receptacle, the opening part of inlet channel is provided with inlet suction port; Be provided with sealing ring in described two annular seal grooves, seal ring set is contained on the rotary drum axle.
The invention has the beneficial effects as follows: the present invention is provided with the two seals ring on corresponding power transmission shaft, and, between this two seals ring, be provided with inlet channel, centrifuge in the course of the work, all the time guarantee that air pressure in the inlet channel is than the air pressure height in the chassis cavity, so guaranteed that the gas in the chassis cavity can not be leaked in the surrounding air effectively, thereby avoided toxic gas that operating personnel's human body is damaged.
