Description

TECHNICAL FIELD

[0001] The utility model belongs to pump cold box's improvement related technical field, specifically related to a pump cold box that can improve the safe and stable performance of equipment, prolong the service life of equipment. BACKGROUND

[0002] Pump cold box is an important part in oxygen generating equipment, and if the pipeline of pump cold box is not reasonably arranged, the pump body equipment will be damaged or the equipment will fail, so the layout of the pipeline and valve in the pump cold box is particularly important, how to optimize the arrangement of the pipeline and valve to realize the reduction of pressure drop, so as to better ensure the safe operation of the equipment and reduce the risk of equipment shutdown and sanding maintenance, is an urgent technical problem to be solved.

[0003] Therefore, we have developed a pump cold box that can improve the safe and stable performance of equipment and prolong the service life of equipment. SUMMARY

[0004] The utility model discloses a pump cold box that can improve the safe and stable performance of equipment and prolong the service life of equipment.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a pump cold box, comprising a cold insulation box shell, a pump is arranged at the lower part of the cold insulation box shell, a pipeline is arranged in the cold insulation box shell, the pump is communicated with the pipeline, the pipeline is communicated with an automatic valve and a manual valve respectively, the height of the pump inlet of the pump is lower than the pipeline, and is lower than the automatic valve and the manual valve, so that the gas generated by the fluid flow in the pipeline can be avoided to be brought into the pump and damage the equipment.

[0006] Preferably, the spacing between the top of the pipeline and the top of the cold insulation box shell is 100-200mm, so that the fluid in the pipeline is directly introduced to the top panel for reheating, directly pulled up to reduce the elbow, also reduce the pressure drop, use more accurately, and the equipment runs more safely.

[0007] Preferably, the minimum spacing between the reheated pipeline and the side panel of the cold insulation box is also 100-200mm, and finally, the pipeline is communicated with the outside of the cold insulation box shell.

[0008] Compared with the prior art, the utility model provides a pump cold box, which has the following beneficial effects:

[0009] The pump inlet of the pump in the pump-cooled box described in this utility model is lower than the height of the pipeline and lower than the automatic valve and manual valve. This prevents gas generated by the fluid flow in the pipeline from being carried into the pump and damaging the equipment. At the same time, to prevent liquid droplets from being carried to the side panel of the cold box, causing the side panel to frost at low temperatures and affecting the safe use of the equipment, the distance between the top of the pipeline and the top of the cold box shell is 100-200 mm. This allows the fluid in the pipeline to be directly guided to the top panel for reheating. The direct elevation reduces bends and pressure drops, making the use more accurate and the equipment safer to operate. This utility model can improve the safety and stability of the equipment and extend its service life. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-2 This utility model provides a technical solution: a pump-cooled box, including a cold box shell 1; a pump 2 is provided at the lower part of the cold box shell 1; a pipe 3 is provided inside the cold box shell 1; the pump 2 is connected to the pipe 3, and the pipe 3 is connected to an automatic valve (not shown) and a manual valve (not shown) respectively; the height of the pump inlet 21 of the pump 2 is lower than that of the pipe 3, and lower than that of the automatic valve and the manual valve, so as to avoid the gas generated by the fluid flow in the pipe 3 being carried into the pump 2 and damaging the equipment.

[0016] Meanwhile, to prevent liquid droplets from being carried to the side panel of the cold storage box, which would cause the side panel to frost at low temperatures and affect the safe use of the equipment, the distance between the top of the pipe 3 and the top of the cold storage box shell 1 is first set to 100-200 mm. This allows the fluid in the pipe 3 to be directly led to the top panel for reheating, directly raising the pipe and reducing bends, as well as reducing pressure drop, making the use more accurate and the equipment safer to operate. The minimum distance between the reheated pipe 3 and the side panel of the cold storage box is also 100-200 mm. Finally, the pipe is connected to the outside of the cold storage box shell 1 through a pipeline.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The pump inlet 21 of the pump 2 in the pump-cooled box described in this utility model is lower than that of the pipe 3 and lower than that of the automatic valve and manual valve. This prevents gas generated by the fluid flow in the pipe 3 from being carried into the pump 2 and damaging the equipment. At the same time, to prevent liquid droplets from being carried to the side panel of the cold insulation box, causing the side panel to frost at low temperatures and affecting the safe use of the equipment, the distance between the top of the pipe 3 and the top of the cold insulation box shell 1 is 100-200 mm. This allows the fluid in the pipe 3 to be directly led to the top panel for reheating. The height is directly increased to reduce bends and pressure drop, making the use more accurate and the equipment safer to operate. This utility model can improve the safety and stability of the equipment and extend its service life.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
