Embodiment Construction

[0013] A closed five-roll drafting machine heating and holding furnace, see figure 1 with figure 2 The heating and holding furnace includes a shell 1, a furnace door 2, a furnace door lifting mechanism 3, a furnace lining 4, a heating element 5 and a hot air circulation system 6, and the furnace door 2 is arranged on the shell 1 and connected with the furnace door lifting mechanism 3. The furnace lining 4 is fixed on the casing 1, and a thermal insulation layer 41 is provided on the furnace lining 4; the heating element 5 is arranged in the casing 1 and located on both sides of the furnace. The hot air circulation system 6 includes a circulating fan 61 and an air duct 62 in the furnace. The circulating fan 61 blows the heat of the heating element 5 into the working area through the air duct 62 in the furnace.

[0014] Concrete reference of the present invention is as follows:

[0015] 1. Maximum temperature: 250°C

[0016] 2. Working temperature: 120-200℃

[0017] 3. Heat...

Abstract

The invention discloses a heat holding furnace for a drafting machine. The heat holding furnace comprises a shell, a furnace door, a furnace door lifting mechanism, a furnace lining, heat elements and a hot wind circulating system, wherein the furnace door is arranged on the shell and connected with the furnace door lifting mechanism; the furnace lining is fixed on the shell; a heat insulating layer is arranged on the furnace lining; the heat elements are arranged in the shell and positioned at two sides of a hearth; and the hot wind circulating system comprises a circulating fan and an air flue in the furnace, and the circulating fan blows the heat of the heat elements to a work area through the air flue in the furnace. The heat holding furnace has good heat and insulation effect, safety, reliability and long service life.

Description

technical field [0001] The invention relates to heat preservation equipment, in particular to a heating and heat preservation furnace for a drafting machine. Background technique [0002] The drafting machine is a drafting and twisting equipment used in the production process of high-performance special fibers, polyester, polypropylene multifilament fibers, polypropylene aramid fibers, etc. After drafting and twisting, it has a certain linear density, Strength, elongation and other physical properties can be used for weaving directly or after processing. The drafting machine is divided into several types of drafting machines, such as single-roll stretching machine, two-roll stretching machine, three-roll stretching machine, five-roll stretching machine, and seven-roll stretching machine. Convenient and reliable. The drawing machine needs to heat and keep the drawn fibers warm during the drawing process. The heating and heat preservation form of the existing drafting machi...
