Description

The equipment that bakes that is used for pad-dry-cure dyeing

Technical field

The utility model relates to a kind of dyeing machine, particularly a kind of equipment that bakes that is used for pad-dry-cure dyeing.

Background technology

The effect of printing and dyeing baker is that the gas that will heat blows to fabric face, transmits heat and makes the DISPERSE DYES distillation of having dried on the fabric enter the terylene lattice and fixation.The heater of this kind equipment use mainly contains burning type heater, hotline heater at present, but has following deficiency:

1, the burning type heating adds hot-air by combustion oil, coal gas etc., quick heating, use more convenient, but produce pernicious gas and tar in the combustion process, influential to fabric and environment, be unfavorable for environmental protection, and the difficult control of the drying room left, center, right temperature difference, the moisture fluctuation scope is big, and is influential to product quality, and application apparatus has the MH682 of Shanghai Printing ﹠ Dyeing Machinery Factory baker.

Though 2, conduction oil indirect automatic control degree is higher, have a narrow range of temperature, the management cost that blow-on, blowing out and oil oven clean producing improves.Application apparatus has the M1861Y of Huangshi machinery plant baker.

In the printing and dyeing baker, Shang Weiyou adopts steam as the application that bakes thermal source at present.Main cause is that Steam Heating is difficult to reach the required technological temperature of pad-dry-cure dyeing, and the pressure of steam is relatively also higher to the requirement of equipment, needs to solve technical barriers such as security and economy.

Summary of the invention

The technical problems to be solved in the utility model provides the equipment that bakes of a kind of easy temperature control, clean environment firendly.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of equipment that bakes that is used for pad-dry-cure dyeing, comprise drying room and the heater that bakes that is positioned at drying room, circulating fan, last lower air duct, hot-rolling, described hot-rolling is on described between the lower air duct, also comprise high pressure drum and low-pressure drum, the described heater that bakes is a steam heater, described steam heater comprises casing, fin, the steam pipe group, air intake and venthole, described steam pipe group is fixed in the described casing by many metal tubes and constitutes, the two ends of described steam pipe group are communicated with described air intake and venthole respectively, and described fin covers the outside of described steam pipe group; The air intake of described steam heater inserts steam line through valve and described high pressure drum, and the venthole of steam heater inserts the back-steam pipeline through valve and low-pressure drum.

Another technical scheme is improved the above-mentioned heater that bakes that bakes equipment, increased an auxiliary electrical heating part, the described heater compartment that bakes is divided into forward and backward casing, be the steam pipe group in the casing before described, be provided with many electrothermal tubes in the described rear box, described electrothermal tube is connected with electric control system.

Owing to the heater that bakes of the utility model employing, be to be the steam heater of thermal source with steam, therefore have the characteristics of clean environment firendly, easy temperature control; If adopt the auxiliary electrical heating, can shorten the heating-up time, help controlling more accurately temperature.The equipment that bakes of the present utility model, technological temperature control accurately, the actual measurement drying room left, center, right temperature difference is less than 1%, and constant product quality, the aberration of production are little, high quality of products such as the high-count and high-density down cloth of suitable exploitation high added value, cartographic bi-bomb cloth, the hydrophilic moisture permeable dacron of Kemankesi.This heater can not produce pollution to the fabric and the environment of processing, and the stockinette of Sheng Chaning meets the requirement that the du pont company stockinette does not have burnt gas absorption in process of production fully thus.

The equipment of baking of the present utility model can directly use the afterheat steam of steam power plant, has not only realized making full use of of the energy, can save outside boiler fixed investment and the management maintenance expense, and daily energy consumption cost is also very low.Therefore, the utility model utilizes the printing and dyeing enterprise of steam power plant's afterheat steam that a kind of desirable equipment is provided for having ready conditions.
