Abstract
The utility model discloses an evacuating system of a vacuum drying oven, which comprises a two-stage Roots vacuum pump (3) and a water ring vacuum pump (4), wherein the front part of the Roots vacuum pump is orderly connected in series with a pipeline cooling dehydrator (1) and an air-liquid separator (2). The evacuating system is adopted to improve the evacuating rate of the vacuum pump so that the evacuating degree of a vacuum system reaches the requirement in shorter time, and the utility model has the advantages of energy consumption saving, work efficiency enhancement and production capacity of devices enhancement.
Description
Technical field
The utility model relates to a kind of evacuation system that is applicable to vacuum drying chamber.
Background technology
The evacuation system of present vacuum drying chamber, be by the two-stage trailing plants thatch vavuum pump that is provided with on the pipeline of finding time, add that a water ring vacuum pump constitutes, the incipient stage that is vacuumizing, owing to contain a large amount of water vapours in the air, cause the load of vavuum pump group big, the speed of exhaust is little, make the pumpage of whole system relatively poor, suction is poor.
Summary of the invention
The utility model provides a kind of evacuation system of vacuum drying chamber, it can improve the speed of exhaust of vavuum pump greatly, makes the suction of vacuum system reach requirement in the very short time, thereby saves energy consumption, increase work efficiency, also promptly improved the production capacity of equipment.
The technical solution adopted in the utility model is as follows: a kind of evacuation system of vacuum drying chamber, it comprises two-stage trailing plants thatch vavuum pump and water ring vacuum pump, is serially connected with pipeline cooled dehydrated device and institute's liquid/gas separator before the described trailing plants thatch vavuum pump successively.
In the utility model, described pipeline cooled dehydrated device is a shell and tube cooler; Described water ring vacuum pump is provided with more than one; Described gas-liquid separator is the two-stage gas-liquid separator.
After adopting as above technical scheme, pipeline cooled dehydrated device is a shell and tube cooler, it is condensed into water with the water vapour of vacuum drying chamber material mouth, the blowdown by the two-stage gas-liquid separator separates again, thereby reduce the load of vavuum pump group, because the volume ratio of water vapour and water is sizable, water vapour is become water can improve a lot to the speed of exhaust that improves vavuum pump, make vacuum system reach requirement in the very short time, greatly reduce energy consumption, improve efficient, equally also improved the production capacity of equipment.The configuration of two groups of Roots vaccum pumps designs for the vacuum that promotes the speed of exhaust and system, can shorten the drying time of material like this, improves production capacity.The configuration of many water ring vacuum pumps is when containing big water gaging in the material, and the initial stage can produce a large amount of water vapours, vacuum can not fast lifting and is provided with, it can determine the platform number of turn on pump according to the different stages, to satisfy the requirement of system's operation, system is rationalized.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model
The specific embodiment
According to shown in Figure 1, the evacuation system of the utility model vacuum drying chamber, it is connected in series successively by pipeline cooled dehydrated device 1, two-stage gas-liquid separator 2, two-stage trailing plants thatch vavuum pump 3 and water ring vacuum pump 4 and forms.Pipeline cooled dehydrated device 1 is connected with vacuum drying chamber 5, and it is a shell and tube cooler, and good cooling results can be cooled to water with water vapour rapidly.Water ring vacuum pump 4 can have many, determines whether to start simultaneously according to the situation of material in the vacuum drying chamber 5.Big water gaging is arranged in material, when producing a large amount of water vapours in the early stage, can start several water ring vacuum pumps, improve the suction of drying box 5 fast; And when suction reaches certain value, then can close down several water ring vacuum pumps wherein, to reduce the energy consumption of system.
Claims (4)
1, a kind of evacuation system of vacuum drying chamber, it comprises two-stage trailing plants thatch vavuum pump (3) and water ring vacuum pump (4), it is characterized in that preceding pipeline cooled dehydrated device (1) and the gas-liquid separator (2) of being serially connected with successively of described trailing plants thatch vavuum pump (3).
2, the evacuation system of vacuum drying chamber according to claim 1 is characterized in that described pipeline cooled dehydrated device (1) is a shell and tube cooler.
3, the evacuation system of vacuum drying chamber according to claim 1 is characterized in that described water ring vacuum pump (4) is provided with more than one.
