Heat exchanger and bell-type furnace with same

Abstract

The invention discloses a heat exchanger and a bell-type furnace with the same. The heat exchanger comprises a shell and a water cooling pipeline for allowing cooling water to pass through, the shell is provided with a heat exchange cavity for allowing gas to pass through, the heat exchange cavity is divided into a plurality of gas chambers, and the multiple gas chamber communicate with one another through communicating holes; the shell is provided with a gas inlet communicating with one gas chamber and a gas outlet communicating with the other gas chamber, and the water cooling pipeline penetrates through the at least two gas chamber. The heat exchanger has the advantages of compact structure, low cost, good heat exchange efficiency and heat exchange effect and the like. The bell-type furnace comprises a furnace body, a kiln car, a heating system, a gas inlet system and a cooling system, the cooling system comprises a fan, a water cooling machine and the heat exchanger, the gas inlet communicates with the hearth of the furnace body through the gas inlet pipeline, the gas outlet communicates with the hearth of the furnace body through a gas outlet pipeline, the two ends of the water cooling pipeline are connected with the water cooling machine, and the fan is arranged on the gas outlet pipeline. The bell-type furnace has the advantages of simple and compact structure, low cost, good heat exchange performance and the like.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a heat exchanger and a bell furnace with the heat exchanger. Background technique [0002] The bell furnace has excellent characteristics such as good temperature uniformity, flexible atmosphere furnace pressure control, easy maintenance, and high level of automation. It is widely used in magnetic materials, special ceramics, functional ceramics, electronic components and other fields, especially in some subdivision For high-end products in the field, the bell furnace is an essential key sintering equipment. At present, the development of new materials is changing with each passing day. From the beginning of research and development, a new product must go through repeated verifications such as small tests and pilot tests before it can be put into the market. Among them, the small test and pilot tests are very important. At present, small experimental furnaces su...

Problems solved by technology

However, the bell furnace is a complex thermal system integrating temperature, atmosphere, and pressure. Not only the furnace body includes multiple systems such as heating system, atmosphere system, cooling system, and control system, but also additional cooling towers and tracks And other auxiliary systems, which will undoubtedly increase the cost of use and increase the threshold for users to use experimental bell furnaces, especially for the majority of scientific research institutes.
