Description

Roots type steam compressor

Technical Field

The utility model relates to a roots vapor compressor technical field, in particular to roots type vapor compressor.

Background

The Roots vapor compressor has the working principle that the two impellers rotate in opposite directions, and the gaps between the impellers and the wall plates are extremely small due to the impellers, the impellers and the casing, so that a vacuum state is formed at an air inlet, tail gas of the reaction kettle enters an air inlet cavity under the action of atmospheric pressure, then two blades of each impeller, the wall plates and the casing form a sealed cavity, the air in the air inlet cavity is continuously brought to an air outlet cavity by the sealed cavity formed by the two blades in the rotation process of the impellers, and the impellers in the air outlet cavity are meshed with each other, so that the air between the two blades is extruded out, the continuous operation is realized, low-temperature and low-pressure unsaturated vapor is formed, and the tail gas is continuously conveyed to an air outlet from the air inlet.

Because every component in the working chamber among the roots's fan all adopts clearance fit, does not have the friction, consequently has certain requirement to the air condition of carrying, contains a large amount of dusts, granule dust in the air can influence roots's steam compressor's working life to increase the noise that its during operation produced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a roots type vapor compressor can effectively filter the dust granule in the input gas, reduces its influence to roots vapor compressor body, noise abatement's production.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the Roots type steam compressor comprises a compressor body and a U-shaped pipe, wherein an air outlet pipe is arranged at the bottom of the compressor body, an air inlet pipe is arranged at the top end of the compressor body, one end of the U-shaped pipe is communicated with the air inlet pipe through a connecting pipe, the other end of the U-shaped pipe is connected with an air supply pipe, and a filtering component is arranged on the connecting pipe.

Furthermore, the connecting pipe is provided with a mounting groove, and the mounting groove is provided with a slot; the filter assembly comprises an arc-shaped mounting plate which can be spliced on the slot, the outer side of the arc-shaped mounting plate is fixedly connected with a handle, and a plurality of filter screens are fixedly connected with the inner side of the arc-shaped mounting plate.

Furthermore, a sealing ring is arranged at the joint of the mounting groove and the arc-shaped mounting plate.

Furthermore, the top of the low-level section of the U-shaped pipe is communicated with a water inlet pipe, and a first butterfly valve is installed on the water inlet pipe.

Furthermore, the bottom of the low section of the U-shaped pipe is communicated with a drain pipe, and a second butterfly valve is installed on the drain pipe.

The utility model has the advantages that:

can effectively filter the dust granule in the input gas through filtering component, reduce its influence to the roots vapor compressor body, improve stability in use, the production of noise abatement.
