Detailed implementation mode

[0024] An embodiment of the present utility model provides an automatic regulator for the oxygen concentration in a cold box. As Figures 1-4 shown, it includes a regulator cylinder 101. On one side inside the regulator cylinder 101, there is a working chamber 111 with an opening facing outwards. One side wall of the working chamber 111 is communicated with an input pipeline 104 with an opening facing outwards. The input pipeline 104 is connected to the oxygen input. On one end face of one side of the regulator cylinder 101, a detachable mounting cover plate 105 is installed. The mounting cover plate 105 and the regulator cylinder 101 are fixedly installed through a stabilizing clamp plate 102. On one end face of one side of the mounting cover plate 105, an output pipeline 117 with an opening facing outwards is communicated. The output pipeline 117 is connected to the output pipeline.

[0025] Further, the stabilizing clamp plate 102 is divided into two arc-shaped plates and is hinged at the tail end. On the other end face of the stabilizing clamp plate 102, a horizontal mounting plate is fixedly provided. The upper and lower mounting plates are fixedly connected through a connecting thread 110.

[0026] Further, on the outer end face of one side of the bottom stabilizing clamp plate 102, a mounting base plate 109 is fixedly provided. On the lower end face of the mounting base plate 109, a vertical support rod 106 is fixedly provided.

[0027] Further, a support base 108 is fixedly installed on the lower end face of the support rod 106. A shock-absorbing spring 107 is installed between the support base 108 and the support rod 106.

[0028] It should be further noted that the shock-absorbing spring 107 is a shock-absorbing spring in the prior art and can play the role of stable support.

[0029] Further, a regulator 115 is arranged inside the working chamber 111. The regulator 115 is fixedly connected to the inner wall of the working chamber 111 through a support plate 114.

[0030] Further, on one end face of the regulator 115 close to the input pipeline 104, a telescopic adjusting telescopic rod 116 is provided. On one end face of the adjusting telescopic rod 116, an adjusting plate 112 is fixedly connected.

[0031] Further, a circular ring-shaped annular fixing plate 113 is fixedly arranged on the inner wall of the working chamber 111 and on one side of the regulator 115. The annular fixing plate 113 is located between the adjusting plate 112 and the regulator 115. The cross-sectional area of the adjusting plate 112 is larger than the inner circular cavity of the annular fixing plate 113. A return spring 120 is fixedly connected between the adjusting plate 112 and the regulator 115.

[0032] It should be further noted that a control component is provided inside the regulator 115, and the control component can control the telescopic movement of the adjusting telescopic rod 116.

[0033] Further, electromagnetic valves 118 are fixedly arranged inside the input pipeline 104 and the output pipeline 117, and a concentration detector 119 is fixedly arranged on one side inside the working chamber 111.

[0034] It should be further noted that the electromagnetic valve 118 plays a role in controlling the on-off, and the concentration detector 119 can detect the oxygen concentration of the flowing gas.

[0035] When using this solution, first install the regulator 115 inside the working chamber 111, and use the support plate 114 for support installation and connection. After assembling the adjusting plate 112, at this time, control the adjusting plate 112 to move through the control component inside the regulator 115 and fit with the surface of the annular fixing plate 113. At this time, the air inside the working chamber 111 cannot flow.

[0036] Subsequently, install the installation cover plate 105 on the outer end face of the regulator cylinder 101, and use the installation bottom plate 109 to play a role of closing and stable support. Then connect the input pipeline 104 with the nitrogen input pipeline, connect the output pipeline 117 with the output pipeline, and install the support rod 106 below the installation bottom plate 109 so that the support base 108 contacts the ground, thereby stably supporting the regulator cylinder 101 between the cold box and the nitrogen tank. At this time, the staff can sleeved multiple stable clamping plates 102 on the outer end face of the regulator cylinder 101, and then use the multiple support bases 108 to play a role of stable ground support.

[0037] When performing oxygen output work, first, the staff set an oxygen concentration detector inside the cold box and signal it to communicate with the concentration detector 119. When the oxygen concentration inside the cold box needs to be changed, at this time, the control component is used to control the movement of the adjusting plate 112, thereby changing the size of the gap between the adjusting plate 112 and the annular fixing plate 113. At this time, oxygen is input through one end of the input pipe 104, flows into the working chamber 111, passes through the inner circular cavity inside the annular fixing plate 113 and then outputs outward, and is output to the output pipe through the output pipe 117, thereby inputting nitrogen with different concentrations into the cold box. At the same time, the control component adjusts the telescopic movement of the adjusting plate 112, thereby changing the size of the output nitrogen concentration, and then realizes the autonomous adjustment of the oxygen concentration inside the cold box. At the same time, the support base 108 plays an effect of stable erection and support, thereby improving the processing efficiency of oxygen concentration adjustment.
