Abstract
The utility model discloses a heat treatment cavity of a pilot line heating imine furnace, which comprises a cylindrical furnace body. The heat treatment cavity of the pilot line heating imine furnace is characterized in that the inner wall of the furnace body is an inner hearth, the inner cavity of the inner hearth is the heat treatment cavity, the inner hearth is fixed in the furnace body under the support of a supporting beam, a vacuum forming heating plate is inlayed in the inner side of the inner hearth, an air inlet is arranged at the middle part of the furnace body, the two ends of the furnace body are respectively provided with an end cover, and each end cover is provided with an air outlet. In the utility model, an imported single circuit intelligent temperature controller is used for temperature control, and the heat treatment cavity of the pilot line heating imine furnace has the advantages of high temperature control precision, high temperature stability, low overall equipment energy consumption, attractive and clean appearance, and the like.
Description
Technical field
The utility model belongs to polyimide fiber material production equipment field, specifically belongs to the hot processing chamber of pilot scale line hot imidization stove.
Background technology
Pilot scale line hot imidization A stove specialized designs is applied to the polyimide fiber material in the usefulness of heat-treating below 400 ℃, and the kiln design takes into full account and understand preparation technology's requirement of polyimide fiber material, its specific (special) requirements of As soon as possible Promising Policy.Preparation technology according to material requires independent design, adopts Far-infrared Heating respectively, and far infrared is in conjunction with the heating of auxiliary circulation wind, internal furnace structure.
Equipment is to be used for that the polyamic acid fiber is carried out hot imidization to handle, preparation polyimide fiber material hot treatment stove, and therefore, the accuracy of furnace chamber temperature and stability are very important.The utility model hot imidization stove adopts the gradient increased temperature heat treatment mode, has overcome two sections shortcomings that hot stove technology temperature is controlled inaccuracy and is unfavorable for operating in the past.
In the hot imidization process, consider polyimide fiber pyrolysis phenomenon at high temperature, therefore, the maximum temperature of hot imidization should be not too high.On the other hand, the polyamic acid fiber can produce a large amount of moisture in the process of hot imidization, and moisture is at high temperature evaporated rapidly, and fibrous inside shrinks and produced crackle.Treatment temperature is high more, and moisture generates rapid more, and it is strong that polymer shrinks Shaoxing opera, and crosslinking degree is also bigger, and is therefore easy of more defectives such as fibrous inside formation crackles.Therefore, the hot imidization of polyamic acid fiber need progressively carry out, and takes the staged segmentation to carry out, and high temperature behind the promptly first low temperature helps improving the mechanical property of polyimide fiber.
Summary of the invention
The purpose of this utility model provides a kind of hot processing chamber of pilot scale line hot imidization stove, and the control of import single loop intelligent temperature controller is adopted in temperature control, has characteristics such as temperature-controlled precision height, temperature stability height, and the whole energy consumption of equipment is lower, aesthetic in appearance, clean and tidy.
The technical solution of the utility model is as follows:
The hot processing chamber of pilot scale line hot imidization stove, the body of heater that comprises tubular, the inwall of body of heater is an internal furnace, the inner chamber of internal furnace is a hot processing chamber, internal furnace is fixed in the body of heater by the brace summer rest, and the internal furnace inboard is installed with the vacuum forming heating plate, and the body of heater middle part offers air inlet, the two ends of body of heater are separately installed with end cap, have air outlet in the end cap.
The two ends of described body of heater are respectively arranged with godet roller, and filament passes the inner chamber of internal furnace and twines drive by godet roller.
The utility model heats fibre on four sides by the vacuum forming heating plate, poly-light fireproof construction brick is as brace summer, the chunk formula constitutes the main body of thermal technology's structure, for guaranteeing the uniformity of fire box temperature, warm area not only adopts independent control, and on the layout of heating wire, adopt non-uniform Distribution, adopt the auxiliary circulation supply air system simultaneously.
Internal furnace does not adopt heat-resistant oxidized stainless steel to be welded into the square pipe, takes anti-deformation to handle, and is yielding under the high temperature, fall slag.Be internal furnace convenient for cleaning, indirect offered four groups of detachable cleaning doors.The control of import single loop intelligent temperature controller is adopted in temperature control, has characteristics such as temperature-controlled precision height, temperature stability height, and the whole energy consumption of equipment is lower, aesthetic in appearance, clean and tidy.
