Abstract
The utility model discloses a vacuum drying machine including a circulating water pump, an electromagnetic valve and a filter. One end of the circulating water pump is arranged on a circulating water pipeline while the other end of the circulating water pump is provided with a water circulating vacuum pimp, a fourth roots pump and one end of a third roots pump. The other end of the third roots pump is connected with a first roots pump and an air outlet end of the second roots pump respectively through air pipelines. Air inlet ends of the first roots pump and the second roots pump are connected with the filter through air inlet pipelines. The electromagnetic valve is arranged on the air pipeline between the fourth roots pump and the water circulating vacuum pump. The roots pumps, the water circulating vacuum pump, the circulating water pump and the electromagnetic valve are connected with a control cabinet through cables. The vacuum drying machine can vacuumize a to-be-dried pipeline and clear water and air in the pipeline away. Probabilities of ice blockage and corrosion of the pipeline can be reduced. Service lifetime of the pipeline can be prolonged. And the vacuum drying machine is wide in application range and good in drying effect.
Description
Technical field
The utility model relates to a kind of vacuum drier, particularly a kind of vacuum drier for long distance pipeline and station.
Background technology
In the prior art, long-distance transport pipes need to carry out the water pressure test before operation, and in pigging process, the water in pipeline is difficult for being cleaned, water in pipeline can cause that corrosive pipeline, Hydrate Plugging pipeline, Low-temperature Ice are stifled etc., has a strong impact on the safe operation of pipeline.At present, a long distance pipeline and station dry air drying method that adopt more, the mode of gas in pipelines being replaced by dry air, reach dry object, but that, pipeline many for pipeline specifications rises and falls is large, there was dampness in the air area and can not lead to the long distance pipeline of ball, moisture in pipeline is difficult to remove, and therefore, dry air drying method drying effect is poor.General vacuum drier, also can only meet container and pipeline that volume is less.
Utility model content
The purpose of this utility model is to provide a kind of applied range, vacuum drier that drying effect is good.
For achieving the above object, the utility model is by the following technical solutions:
A vacuum drier, comprises water circulating pump, magnetic valve, filter, and described water circulating pump one end is located on circulating water pipework, and the other end is provided with water ring vacuum pump, the 4th lobe pump, the 3rd lobe pump connecting by gas pipeline successively; The other end of described the 3rd lobe pump is connected with the outlet side of the second lobe pump with the first lobe pump respectively by gas pipeline; The inlet end of described the first lobe pump and the second lobe pump is connected with described filter by admission line, and described magnetic valve is located on the gas pipeline between the 4th lobe pump and water ring vacuum pump; Described lobe pump, water ring vacuum pump, water circulating pump, magnetic valve are connected with switch board by cable.
The first corrugated expansion joint, the second corrugated expansion joint, the 3rd corrugated expansion joint and the 4th corrugated expansion joint are installed on the connection gas pipeline between described the first lobe pump, the second lobe pump, the 3rd lobe pump, the 4th lobe pump and water ring vacuum pump successively.
On the admission line of described the first lobe pump or the second lobe pump, pneumatic operated valve is installed.
Vacuum drier of the present utility model is evacuated by the lobe pump pipeline that will be dried, and water, gas in pipeline are eliminated, and reduces the stifled and corrosion probability of pipeline ice, extends pipeline service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Embodiment of the present utility model, as shown in Figure 1-2: vacuum drier, comprises water circulating pump 6, magnetic valve 12, filter 13.Water circulating pump 6 one end are located on circulating water pipework 14, and the other end is provided with water ring vacuum pump 5, the 4th lobe pump E-4, the 3rd lobe pump E-3 connecting by gas pipeline successively; The other end of the 3rd lobe pump E-3 is connected with the outlet side of the second lobe pump E-2 with the first lobe pump E-1 respectively by gas pipeline; The inlet end of the first lobe pump E-1 and the second lobe pump E-2 is connected with filter 13 by admission line, and magnetic valve 12 is located on the gas pipeline between the 4th lobe pump E-4 and water ring vacuum pump 5; Lobe pump, water ring vacuum pump 5, water circulating pump 6, magnetic valve 12 are connected with switch board by cable.
The first corrugated expansion joint 7a, the second corrugated expansion joint 7b, the 3rd corrugated expansion joint 7c and the 4th corrugated expansion joint 7d are installed on the connection gas pipeline between the first lobe pump E-1, the second lobe pump E-2, the 3rd lobe pump E-3, the 4th lobe pump E-4 and water ring vacuum pump 5 successively; Can effectively avoid equipment in operation process, because of variations in temperature, make to connect gas pipeline and produce stretching or compression stress, cause the generation of device damage accident.
Pneumatic operated valve 8 is installed on the admission line of the first lobe pump E-1, by opening and closing pneumatic operated valve 8, can realizes unit or the duplex running of the first lobe pump E-1 and the second lobe pump E-2, meet the dry requirement of different stations or pipeline.
The utility model can be arranged in skid, is convenient to transportation and execute-in-place.
When needs carry out station or pipeline drying, filter 13 of the present utility model is connected with pipeline flange to be dried, by switch board, start 6 pairs of lobe pumps of water circulating pump, water ring vacuum pump 5 carries out cooling, restart water ring vacuum pump 5, as the first lobe pump E-1, the second lobe pump E-2, the 3rd lobe pump E-3, pressure reduction between the 4th lobe pump E-4 reaches while setting startup value, open successively the 4th lobe pump E-4, the 3rd lobe pump E-3, the second lobe pump E-2 and sieve the first thatch pump E-1, the pipeline that will be dried is evacuated, can be by the water in pipeline, gas is removed, reducing pipeline ice blocks up and corrosion probability, extend pipeline service life.
