Abstract
The utility model discloses a vacuum device of a microwave vacuum drier. The vacuum device comprises a water ring vacuum pump, a buffer tank and a moisture separator, wherein an air exhaust port of the water ring vacuum pump is connected with an air exhaust pipe, the buffer tank is arranged on the air exhaust pipe, the moisture separator is connected with an exhaust hole of the water ring vacuum pump by virtue of an exhaust pipe, and the moisture separator is provided with a tap water inlet pipe, a circulating water gate valve and an overflow pipe. The vacuum device disclosed by the utility model can provide the microwave vacuum drier with a vacuum environment, moreover, the structure is simple, and the practicability is strong.
Description
Technical field
The utility model relates to a kind of vacuum plant of microwave vacuum dryer.
Background technology
At present, in the pharmaceutical equipment field, microwave vacuum dryer is used widely, but the vacuum plant of traditional microwave vacuum dryer can not be realized the absolute vacuum of the inner chamber of whole microwave vacuum dryer.
The utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of vacuum plant of microwave vacuum dryer.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: a kind of vacuum plant of microwave vacuum dryer comprises: the bleeding point of a water ring vacuum pump, described water ring vacuum pump is connected with exhaust tube; Be arranged on the baffle-box on described exhaust tube, the moisture separator be connected with the steam vent of described water ring vacuum pump by blast pipe, described moisture separator is provided with running water water inlet pipe, recirculated water gate valve and overflow pipe.
In one embodiment, also be provided with check-valves on described exhaust tube.
On described baffle-box, vacuum meter is installed.
Compared with prior art, the utility model is by the twitch of water ring vacuum pump, dry chamber in microwave vacuum dryer is evacuated, the baffle-box arranged on exhaust tube has given water ring vacuum pump in the space of bleeding, guaranteed the sealing and circulating of whole device finally by the effect of crossing moisture separator, and simple in structure, practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the vacuum plant of the microwave vacuum dryer the utility model proposes comprises: the bleeding point of water ring vacuum pump 1, water ring vacuum pump 1 is connected with exhaust tube; Baffle-box 2 is installed on exhaust tube, vacuum meter 7 is installed on baffle-box 2, on the exhaust tube between baffle-box 2 and water ring vacuum pump 1, check-valves 6 is installed.The steam vent of water ring vacuum pump 1 is connected with blast pipe, and the end of blast pipe is equipped with moisture separator 3, and moisture separator 3 is provided with running water water inlet pipe, recirculated water gate valve 4 and overflow pipe 5.
During specific works, air-flow is twitched in water ring vacuum pump 1 work from exhaust tube, and air-flow enters baffle-box 2 and cushioned, and then by check-valves 6, from blast pipe, flows out and enters into moisture separator 3, finally will be evacuated chamber and be evacuated.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
