AI Technical Summary

Technical Problem

At this stage, the heat exchanger is more troublesome when removing the clamping bolt and nut assembly, and requires twitching and loosening components one by one.

Method used

An efficient heat exchanger for liquid oxygen production is designed. By setting up a traction frame, cross rod and dual-axis motor to cooperate with each other, when it is necessary to remove the clamping bolt and nut assembly, the biaxis motor is used to drive the bevel gear and threaded rod to rotate, and the slider of the traction frame moves on the threaded rod, so that the traction frame pushes the multiple loose clamping bolt and nut assembly forward.

Benefits of technology

This enables efficient removal of clamping bolt and nut assembly without twitching one by one, simplifying the operation process.

Abstract

The utility model discloses a high-efficiency heat exchanger for liquid oxygen production, including a fixed plate, a clamping plate and a heat exchange plate. Positioning beams are fixedly installed on the rear surface of the fixed plate and at the upper and lower ends, and heat exchange plates are clamped between the positioning beams. Support rods are fixedly installed at the rear end of the positioning beams. Clamping plates are movably installed between the positioning beams and at the rear of the heat exchange plates. Clamping bolt and nut assemblies are provided between the clamping plates and the fixed plates and near both sides. Connecting pipes are fixedly installed on the front surface of the fixed plate and near the four corners. A traction frame is provided in front of the fixed plate. A cross bar is fixedly installed on the top of the support bar, and a protective cover is fixedly installed on the rear surface of the cross bar. The high-efficiency heat exchanger for liquid oxygen production described in the utility model can simultaneously pull multiple loosened clamping bolt and nut assemblies through the cooperation of the traction frame, the cross bar and the dual-axis motor, which makes the disassembly work more convenient.
