Embodiment 1

[0019] A vacuum combined unit,

[0020] Specific steps are as follows:

[0021] A vacuum combined unit, that is, a vacuum unit device combined with a screw vacuum and a Roots vacuum, which includes a screw vacuum pump, a Roots vacuum pump, a pipeline, a pressure buffer tank, a condenser, and a control cabinet.

[0022] One end of the screw vacuum pump is connected to the Roots vacuum secondary pump through a soft connection, and the other end is connected to the wound condenser and the pressure buffer tank through a soft connection; the pressure buffer tank is connected to the wound condenser, and the shell side of the wound condenser is connected to 7 ℃ water or ice salt water, to further recover the volatilized solvent, improve the solvent recovery rate, and reduce exhaust gas emissions; the Roots vacuum pump is a secondary vacuum pump, connected through a pipeline, and then connected to the screw vacuum pump through a soft connection; the switch of the entire vacuum unit is...

Abstract

The invention discloses a vacuum combined unit which is characterized being improved by combining screw vacuum and Roots vacuum. The vacuum combined unit comprises a screw vacuum pump, a Roots vacuum pump, a pipeline, a pressure buffering tank, a condenser and control cabinet. After the screw vacuum pump is mounted on a Roots vacuum unit, a Roots three-stage pump is replaced, and the condenser and the stainless steel pressure buffering tank are additionally arranged, so that a volatilized solvent is further recovered; a switch of the whole vacuum unit is controlled by the control cabinet; and a motor adopts a variable-frequency motor with low power consumption. Compared with the prior art, not only can solvent recovery and material transfer be realized, but also high-vacuum distillation can be carried out, and various vacuum requirements of one chemical production workshop can be met; and the vacuum combined unit has the advantages of simple structure, low cost, energy saving, environment friendliness, low noise, low power consumption, automation in control, high vacuum degree and function diversity.

Description

technical field [0001] The invention belongs to the technical field of vacuum units, and in particular relates to a vacuum combined unit. Background technique [0002] In the field of chemical industry, there are many processes that require vacuum in a workshop, such as vacuum filtration, vacuum drying, vacuum feeding, vacuum concentration, high vacuum rectification, vacuum pumping, etc. One vacuum pump cannot meet the needs of various vacuums. Install multiple sets of vacuum pumps, and need to convert and replace equipment and pipelines between different vacuum pumps. If vacuum pumps with different functions are combined and reformed to form a combined vacuum unit, the advantages of different vacuum pumps can be combined to provide multi-functional vacuum needs. [0003] At present, the screw vacuum pump is a technological product with a very high technical content. It is mainly used in high-purity vacuum processes. The vacuum degree is extremely high, and it can adapt to ...
