All-welded plate heat exchanger

Abstract

The invention discloses an all-welded plate heat exchanger. The all-welded plate heat exchanger comprises supporting legs, a box body, a connecting mechanism installed at the top end of the box body and an adjusting mechanism installed at the bottom ends of the supporting legs, the connecting mechanism comprises a cold liquid outlet, the cold liquid outlet is fixedly installed on the surface of the top end of the box body, the inner surface of the cold liquid outlet is sleeved with a liquid pipe, a rubber ring is arranged on the surface of the top end of the cold liquid outlet, a fixing groove is fixedly formed in the edge of the bottom end of the liquid pipe, a groove is formed in the outer surface of the fixing groove, and a first sliding rail is fixedly connected to the position, located at the top end of the fixing groove, of the bottom end of the side face of the liquid pipe. Compared with the prior art, the all-welded plate heat exchanger has the following beneficial effects that by designing the fixing groove formed in the outer surface of the liquid pipe, a rotating ring installed on the outer surface of the liquid pipe and a sliding block connected with the rotating ring through threads, the cold liquid outlet and the liquid pipe can be fixed conveniently, the situation that due to inconvenient connection between pipelines, the sealing performance of the all-welded plate heat exchanger is reduced is effectively avoided, and therefore, liquid is prevented from leaking.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to fully welded plate heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. There are still various problems in traditional plate heat exchangers, which are difficult to meet the needs of actual use. [0003] For example, an all-welded plate heat exchanger disclosed in the invention with the authorized announcement number CN203100500U, the heat ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fully welded plate heat exchanger to solve the problem that the connection of the heat exchanger is unstable due to the alternation of cold and heat in the connection of the heat exchanger, which affects the sealing of the connection between the flanges and the When the device is installed, the height of the outriggers cannot be adjusted due to the uneven ground, which makes the device shake
