Installation mechanism used for installing inner sleeve in tubular heat exchanger

Abstract

The invention discloses an installation mechanism used for installing an inner sleeve in a tubular heat exchanger. The tubular heat exchanger comprises an outer sleeve, sealing rings arranged on the inner sides of the two ends of the outer sleeve, and the inner sleeve. The installation mechanism is used for installing the inner sleeve into the sealing rings. The installation mechanism comprises a first fixing piece and a second fixing piece, wherein the first fixing piece is arranged outside one end of the outer sleeve in a sleeving mode, the second fixing piece is fixedly connected with the first fixing piece, and one end of the outer sleeve and the second fixing piece are distributed in a spaced mode. The arrangement direction of the first fixing piece and the second fixing piece is identical to the length extending direction of the outer sleeve. A through hole is formed in the second fixing piece. The installation mechanism further comprises a push rod and a handle, wherein the push rod is arranged in the through hole in a penetrating mode, the handle is arranged at the other end of the push rod, and the handle is used for driving the push rod to move in the length extending direction of the push rod during rotation. According to the installation mechanism, the push rod is driven by the rotation of the handle to move at a stable speed so that the inner sleeve can be stably pushed into the outer sleeve; and the acting force is uniform, the integrity of the sealing rings is guaranteed, the labor intensity of installation personnel is relieved, and the installation difficulty is lowered for the installation personnel.

Description

technical field [0001] The invention relates to an installation mechanism for installing an inner casing in a tubular heat exchanger. Background technique [0002] In the floating tube heat exchanger, the thermal expansion of the outer casing and the inner casing tube bundle is free, and the sealing is completely sealed by two sets of sealing rings in the joints on both sides of the outer casing casing, and the inner casing tube bundle can also be completely sealed. Pull out from the seal. [0003] In the floating tubular heat exchanger, before the inner sleeve tube bundle is loaded into the outer sleeve shell, two sealing rings must be installed at the joints on both sides of the outer sleeve shell. Therefore, the frictional resistance of the inner sleeve tube bundle increases when the inner sleeve tube bundle is packed into the outer sleeve shell, making it difficult to push the inner sleeve tube bundle into the outer sleeve shell. The traditional installation method is ...

AI Technical Summary

Problems solved by technology

Due to the uneven force each time during the knocking process and the sealing ring of the outer casing has a certain degree of elasticity, the sealing ring is often damaged

In this installation method, it is difficult for the installer to control the magnitude of the knocking force, which is time-consuming and labor-intensive.
