Split type efficient heat exchanger of bell type furnace

Abstract

The invention discloses a split type efficient heat exchanger of a bell type furnace. Partition plates are arranged at the two ends of the internal part of a shell; a heat exchange assembly is arranged in the shell; on end of a heat exchange pipe is connected with a thermal medium inlet pipe; blocking strips are stuck on the inner walls, corresponding to the end parts of the partition plates, of the shell; a threaded hole is internally connected with a screw rod; heat-insulating assemblies are arranged on the front side and the back side of the shell; a sealing plate is provided with positioning grooves corresponding to the positions of heat-conducting plates; a buffer groove is formed in the middle part of the side surface, near the sealing plate, of an asbestos heat-insulating plate; arc-shaped spring pieces are inlaid on the side surface, near the sealing plate, of a buffer rubber plate; and after the split type efficient heat exchanger of the bell type furnace is used for a periodof time, the thermal medium inlet pipe and a thermal medium discharging pipe can rotate, the partition plates can be pushed along the blocking strips, the heat exchange pipe is taken out, the heat exchange pipe is convenient to disassemble, the inner wall of the shell and the heat exchange pipe are convenient to take out and clean, the screw rod rotates, and the heat-conducting plates move along the outer sides of the heat-conducting plates at the moment to scrape sundries and limescales on the outer side of the heat exchange pipe, so that high heat exchange efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a split-type high-efficiency heat exchanger for a bell furnace. Background technique [0002] The heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid. It is widely used in chemical, petroleum, power, food and many other industrial productions. It is suitable for different media, different working conditions, different temperatures, and different pressures. Heat exchangers have different structural types and various types. In order to save costs, the cold medium for heat transfer is usually air and water. [0003] In the patent application number 201920135082.9, "a split heat exchanger for bell furnace" is mentioned. This patent is used for the split heat exchanger of bell furnace. The space of the heat exchanger is occupied. At the same time, the flow velocity of the cold medium can be reduced by blocking the cold medium through ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a split-type high-efficiency heat exchanger for a bell-type furnace, which can effectively solve the problem that after the heat exchanger is used for one end of the above-mentioned background technology, foreign matter and scale are easily adhered to the outside of the heat exchange tube, which affects the heat exchange. Efficiency, and it is difficult to clean up, which affects the normal use of the problem
