Heat setting furnace for paper making felt

Abstract

The invention discloses a heat setting furnace for a paper making felt. The heat setting furnace for the paper making felt comprises a furnace body frame (10), multiple heating pipe retainers (20), multiple heating pipes (30), a controller (40), a heat sensor (31) and an alarm apparatus, wherein a temperature heater is connected with the heating pipes (30) and used for providing a heat source for the heating pipes. The heat setting furnace for the paper making felt can ensure that heat is even when the paper making felt is subjected to heat setting, the quality of the paper making felt is improved, and the heat setting furnace is provided with a control system, enables the temperature to be constant within a required temperature interval and plays a good heat setting role.

Description

technical field [0001] The invention relates to a heat-setting furnace, in particular to a heat-setting furnace for paper-making felts. Background technique [0002] Papermaking felt is an important consumable material in the papermaking industry. With the continuous development of the papermaking industry, higher and higher requirements are placed on the performance of papermaking felts. Excellent papermaking felts are useful for the papermaking industry to reduce consumption and improve Product quality and production efficiency. As the last processing procedure in the production of papermaking felts, heat setting plays a very important role in the performance and quality stability of the felts. [0003] Currently, electric heating heat setting furnace is generally used for heat setting of papermaking felt, and all parts of the heat setting furnace are fixedly connected. When the above heat setting furnace heats and sets the papermaking felt, each part will expand when the...

Problems solved by technology

[0003] Currently, electric heating heat setting furnace is generally used for heat setting of papermaking felt, and all parts of the heat setting furnace are fixedly connected. When the above heat setting furnace heats and sets the papermaking felt, each part will expand when the temperature rises , and then deform the entire furnace body

After the furnace body is deformed, the heat for heating and shaping the papermaking felt is uneven, which will affect the quality of the papermaking felt.

[0004] In order to prevent the deformation of the heat setting furnace, in the existing design, the heat setting furnace is often made stronger, and better or larger materials are selected. On the one hand, the cost is increased, and on the other hand, the deformation caused by thermal expansion is still unavoidable.
