Abstract

The utility model discloses a Nitrogen protection explosion-proof device of a centrifugal machine, mainly comprising an air inlet pipe and an air returning pipe communicating with the inner chamber of a machine shell. An electromagnetic valve is arranged on the air inlet pipe. An oil mist separator, an air cleaner, a corrosive gas filter, an air pump and an oxygen analyzer are positioned on the air returning pipe. The devices have advantages that the oxygen analyzer can exactly analyze the content of the oxygen in the machine shell in order to exactly control the nitrogen-filled content in the machine shell, so the content of the oxygen in the machine shell can be controlled. The density of the oxygen in the machine shell can be kept in a safe range at all times. The explosive accident can not happen, and the centrifugal machine can safely work with high efficiency.

Description

Centrifuge nitrogen protection explosion-protection equipment
Technical field
The utility model relates to the nitrogen protection explosion-protection equipment in the centrifuge.
Background technology
Centrifuge is widely used in the industries such as pharmacy, chemical industry, and its effect is: be mainly used to separate and dry the liquid composition in the material.The primary structure of centrifuge is: damping base, casing is installed on the damping base, be provided with rotary drum in the casing, the top of casing is provided with cover, on the sidewall of rotary drum, offer a lot of through holes, the inwall of rotary drum is provided with filter screen, and rotary drum is driven by drive unit and runs up, and feed arrangement also is installed on cover.During work, the material of need being sloughed the liquid composition by feed arrangement imports in the rotary drum, and the rotary drum of high speed rotating throws away rotary drum with the liquid composition in the material, reaches the purpose of Separation of Solid and Liquid.When using centrifuge to separate inflammable, explosive material, for preventing blast accident, also be provided with usually and fill the nitrogen explosion-protection equipment, that is: the nitrogen source of the gas charges into nitrogen by air inlet pipe in casing, and the air in the casing is discharged casing by muffler; When the concentration of nitrogen in the casing reach certain value, when making in the casing concentration of oxygen be lower than separation of material to fire required value, centrifuge just can carry out mask work safely, just blast accident can not take place.But, can only control oxygen content in the casing by rule of thumb by operating personnel at present, on tenterhooks always during operation, production efficiency is very low.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of nitrogen protection explosion-protection equipment that can effectively control oxygen concentration in the casing.
For achieving the above object, the technical solution adopted in the utility model is: described centrifuge nitrogen protection explosion-protection equipment mainly comprises: air inlet pipe that communicates with chassis cavity and muffler, and air inlet pipe is provided with magnetic valve; Be characterized in: on muffler, also be respectively arranged with oil mist separator, air cleaner, etchant gas filter, air pump and analysis of oxygen content device.
The further technical scheme of the utility model is: the two ends of magnetic valve are parallel with micro-blowdown pipe on air inlet pipe.
The utility model further technical scheme is: micro-blowdown pipe is provided with valve.
The utility model has the advantages that: the analysis of oxygen content device can more accurately analyze the oxygen content in the casing, just can more accurately control the amount of filling nitrogen in the casing, thereby control the content of oxygen in the casing, the interior concentration of oxygen of casing is remained in the safe scope, just blast accident can not take place, centrifuge just can safety, work efficiently.
Description of drawings
Fig. 1 is the structural representation of centrifuge nitrogen protection explosion-protection equipment described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1, centrifuge nitrogen protection explosion-protection equipment described in the utility model mainly comprises: the air inlet pipe 3 and the muffler 2 that communicate with the inner chamber of casing 1, and air inlet pipe 3 is provided with magnetic valve 6; On muffler 2, also be respectively arranged with oil mist separator 13, air cleaner 12, etchant gas filter 11, air pump 10 and analysis of oxygen content device 9.In the present embodiment, the two ends of magnetic valve 6 also are parallel with micro-blowdown pipe 7 on air inlet pipe 3; Micro-blowdown pipe 7 is provided with valve 8.
The operation principle of above-mentioned nitrogen protection explosion-protection equipment is: after centrifuge starts; open magnetic valve 6; nitrogen source of the gas 14 charges into nitrogen by gas tube 4, air inlet pipe 3 in the inner chamber of casing 1, discharge original air in the casing 1 by muffler 2, to reduce the content of oxygen in the casing 1.When filling nitrogen, air pump 10 is also at extracting gases in the casing 1 constantly, after the gas that extracts is removed mist of oils, is removed moisture and impurity, removes corrosive gas such as sulfurous gas through etchant gas filter 11 through air cleaner 12 through oil mist separator 13 respectively, finally deliver to the content that detects oxygen in the analysis of oxygen content device 9, when detected oxygen content is lower than the lower limit that sets, analysis of oxygen content device 9 just sends signal, and closes magnetic valve 6 automatically.At this moment, the concentration of the nitrogen in the casing 1 just remains in the scope of a safety, just blast accident can not take place, and centrifuge just can carry out work safely, efficiently.Meanwhile, in the present embodiment, because valve 8 can be arranged on normally open, therefore nitrogen source of the gas 14 can pass through gas tube 4, trace blowdown pipe 7 and air inlet pipe 3 are carried out low discharge and are replenished in casing 1, to guarantee in the muffler 2 certain reflux gas being arranged, thereby the oxygen content when making analysis of oxygen content device 9 monitor the centrifuge operate as normal in real time in the casing 1, when detected oxygen concentration is higher than the higher limit that sets, analysis of oxygen content device 9 just can send alarm signal, and open magnetic valve 6 automatically by control device, replenish nitrogen toward casing 1 interior big flow, be lower than till the lower limit that sets up to detected oxygen concentration.So circulate, reach the defencive function of real-time monitoring.Discharge by blast pipe 5 through the gas that analysis of oxygen content device 9 detected.
When in centrifuge, being provided with gas auxiliary slagging-off scraper and gas backwash deslagging device, also must using the nitrogen in the nitrogen source of the gas 14, and can not use common air; That is: provide source of the gas by the tracheae 15 and 16 that communicates with nitrogen source of the gas 14 to gas backwash deslagging device and the auxiliary slagging-off of gas scraper respectively.
