Description

Technical Field

[0001] The utility model relates to the technical field of oxygen compressors, in particular to a circulating water circulation treatment mechanism for an oxygen compressor. Background Art

[0002] In the gas industry, if users have requirements for oxygen pressure, they generally achieve this through two ways. First, through heat exchange with liquid oxygen through a heat exchanger, liquid oxygen quickly vaporizes to form high-pressure oxygen. Second, the oxygen pressure is compressed to a specified pressure through an oxygen compressor. An oxygen compressor is a compressor specifically used to compress oxygen. Working principle: Oxygen accounts for 20% of the air, nitrogen accounts for nearly 80%, and the rest are rare gases. The oxygen machine is actually a compressor equipped with special accessories such as molecular sieves. When working, the oxygen machine compresses and cools the air to a liquid state, and uses the different vaporization temperatures of liquid oxygen and liquid nitrogen and molecular sieves to separate them, thus making liquid oxygen, which can be bottled and sold, and the by-product is nitrogen.

[0003] When the oxygen compressor currently used is working, there is no drain valve at the blind end of the circulating water pipeline, and it cannot be flushed online. When cleaning the pipeline, it is necessary to shut down, which will cause damage to economic benefits. At the same time, if the inside of the pipeline cannot be cleaned in time, corrosion will occur under the pipeline, affecting its service life. Therefore, an oxygen compressor circulating water circulation treatment mechanism is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an oxygen compressor circulating water circulation treatment mechanism, which has the function of realizing online flushing operation, which can not only ensure the normal operation of the equipment without stopping, but also reduce the internal under-pipe corrosion of the pipeline caused by sludge deposition at the blind pipe end to achieve the effect of online treatment, realize the advantage of reducing economic benefits due to shutdown, and solve the problem that sludge in the equipment water pipeline cannot be flushed online.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxygen compressor circulating water circulation treatment mechanism, comprising an inlet blind pipe body, one end of which is fixedly mounted with a sealing flange, and further comprising a connecting pipe;

[0006] The connecting pipe is connected and installed on the sealing flange;

[0007] Among them, the lowest point of the bottom of the inner wall of the connecting pipe coincides with the lowest point of the bottom of the inner wall of the inlet blind pipe body;

[0008] Wherein, one end of the connecting pipe away from the sealing flange is connected with a sewage valve body.

[0009] When using an oxygen compressor circulating water circulation treatment mechanism in the technical solution, a sealing flange is fixedly installed on the inlet blind pipe body, and a reserved hole is opened in the sealing flange. At the same time, a connecting pipe with a second flange is welded at the reserved hole. After the welding of the connecting pipe is completed, a drain valve is connected and installed at the end of the connecting pipe away from the sealing flange through the second flange. When flushing the pipeline, the drain valve body is opened to discharge the liquid in the inlet blind pipe body, and the flushing operation of the pipeline is realized during the discharge process.

[0010] Preferably, the upper end surface of the inlet blind tube body is opened and connected with a liquid outlet pipe, the other end of the inlet blind tube body is a liquid inlet end, and one end of the inlet blind tube body close to the sealing flange is connected with a first flange.

[0011] A hole is opened on the upper end surface of the inlet blind tube body and a liquid outlet pipe is connected and installed. At the same time, the other end of the inlet blind tube body is a liquid inlet end, so that the liquid entering the inlet blind tube body can be discharged through the liquid outlet pipe, thereby forming a circulation.

[0012] Preferably, a reserved hole is opened on the sealing flange, the connecting pipe is welded and installed on the outside of the reserved hole, and the sealing flange is fixedly connected to the first flange by mounting bolts.

[0013] By opening a reserved hole on the sealing flange and welding the connecting pipe to the outside of the reserved hole, the connecting pipe and the inlet blind pipe body can be connected and installed, so that the liquid in the inlet blind pipe body can flow into the connecting pipe. At the same time, the sealing flange is fixedly connected to the first flange by installing bolts, which makes maintenance more convenient and quick.

[0014] Preferably, the inner diameter of the connecting pipe is one quarter of the inner diameter of the inlet blind pipe body, and the end of the connecting pipe away from the sealing flange is connected to and installed with a second flange.

[0015] By making the inner diameter of the connecting pipe one-fourth of the inner diameter of the inlet blind pipe body, this can not only ensure the water consumption required for equipment operation, but also minimize the consumption of circulating water, thereby saving energy.

[0016] Preferably, one end of the drain valve body is fixedly connected to the second flange by means of mounting bolts, and the drain valve body adopts a flange-type butterfly valve structure design.

[0017] By adopting the flange butterfly valve structure design for the sewage valve body, the flange butterfly valve is selected because the butterfly valve has a large flow area, which is conducive to sewage discharge and has a good cutoff effect, and can flush out the silt in the pipeline to a certain extent.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] The utility model provides a connecting pipe, and connects and installs the connecting pipe on the sealing flange. At the same time, the lowest point of the bottom of the inner wall of the connecting pipe coincides with the lowest point of the bottom of the inner wall of the inlet blind pipe body. In order to completely drain the sludge in the pipeline, the lowest point inside the connecting pipe mouth must coincide with the lowest point inside the blind flange. Only in this way can it be ensured that the sludge cannot be flushed out and that the residual sludge can be completely cleaned. At the same time, the end of the connecting pipe away from the sealing flange is connected and installed with a sewage valve body. By adopting a flange-type butterfly valve structure design for the sewage valve body, the butterfly valve has a large flow area, is conducive to sewage discharge, and has a good cutoff effect, and can flush out the sludge in the pipeline to a certain extent. In specific operations, the sealing flange is fixedly installed on the inlet blind pipe body, and a reserved hole is opened in the sealing flange. At the same time, a connecting pipe with a second flange is welded at the reserved hole. After the welding of the connecting pipe is completed, a drain valve is connected and installed at the end of the connecting pipe away from the sealing flange through the second flange. When flushing the pipeline, the liquid in the inlet blind pipe body is discharged by opening the drain valve body, and the pipeline is flushed during the discharge process, thereby achieving online flushing operations, which can not only ensure the normal operation of the equipment without stopping, but also reduce the internal under-pipe corrosion of the pipeline caused by silt deposition at the blind pipe end to achieve the effect of online treatment.

In order to completely drain the sludge in the pipeline, the lowest point inside the connecting pipe mouth must be coincident with the lowest point inside the blind plate flange. In this way, it is possible to ensure that the sludge cannot be flushed out and the residual sludge can be completely cleaned.

At the same time, the sealing flange 4 is fixedly connected to the first flange 3 by installing bolts, which makes maintenance more convenient and quick.

[0036] Furthermore, the inner diameter of the connecting pipe 5 is one quarter of the inner diameter of the inlet blind pipe body 1 , and one end of the connecting pipe 5 away from the sealing flange 4 is connected and installed with a second flange 6 .
