Embodiment Construction

[0025] The following combined with the accompanying drawings figure 2 The present invention is described further, as two kinds of fans of preheating Φ845 * 175 and Φ745 * 170, can realize technical scheme of the present invention by following method:

[0026] ①, δ5~δ6 steel plate blanking, the size of the circular steel plate blanking is about 300 larger than the diameter of the fan, welded into an upper and lower openable circular upper cover shell (sequence 1), a circular lower seat shell (sequence 8), The inner space height of the upper and lower shells is about 200 higher than that of the fan;

[0027] ②. Weld two upper cover handles (serial 3) next to the upper cover shell (sequence 1) to prepare for removing the upper cover during operation;

[0028] ③. Evenly distribute and weld 8 load-bearing partitions in the shell of the lower seat (sequence 5);

[0029] ④. Install high-grade thermal insulation cotton in the shell of the upper cover (sequence 2), and install high-...

Abstract

The invention discloses a special round heating furnace for a fan, which is structurally characterized in that the shape and the inner cavity of the furnace are round; the diameter and height of the inner cavity of the furnace are respectively 40-140mm and about 50mm larger than those of a workpiece; eight bearing clapboards are evenly distributed and welded in a lower seat shell; the furnace is in a structure which can be vertically opened or closed, and upper cover shell and lower seat shell are made of steel structures by welding; eight heating unit bodies are mounted in the lower seat, and incoming lines and outgoing lines of the eight heating unit bodies are respectively connected to a temperature display control system, eight heating unit bodies are all controlled independently; and insulating materials in both upper cover shell and lower seat shell are made of high-grade fire-resistant cotton. Compared with the existing heating equipment, the special round heating furnace has the obvious effects of low manufacturing cost, high heating efficiency, less power of complete set of equipment, small occupied area, good mobility and convenient operation, wherein the manufacturing cost is 1 / 10 of the cost of the existing heating equipment, the heating efficiency is improved by 40-50% on average, and the power of the complete set of equipment is 1 / 3-1 / 4 of that of the existing heating equipment.

Description

technical field [0001] The invention relates to a special heating equipment, in particular to a special circular heating furnace for a fan. Background technique [0002] The fan is an important part of large motors and generators. The material is low-alloy steel. In order to ensure the quality of the weld, it needs to be preheated during welding. The preheating temperature is 400°~450°. The existing heating equipment uses It is a medium-sized box-type electric furnace. [0003] The box-type electric furnace used to heat the fan has the following disadvantages: [0004] ①, high manufacturing cost; [0005] ②. The supporting power is large, generally 100-110kw (the furnace mouth is 600-900mm); [0006] ③, thermal efficiency is relatively low; [0007] ④, large area; [0008] ⑤. Inconvenient operation. Contents of the invention [0009] In order to solve the shortcomings of the existing equipment, the invention provides a circular heating furnace dedicated to fans, whic...
