Abstract

The utility model relates to a high effective hot roller body used in chemical fiber production . The utility model is structurally characterized in that a liquid cavity is arranged in the interior of the side wall of the roller body. The liquid cavity is filled with liquid of large thermal capacity. The application of the high effective hot roller body can either save the energy or increase the temperature control precision of the hot roller; the surface temperature of the roller can be controlled in the range of plus or minus 1 Celsius system.

Description

Efficient hot-rolling roll body

Technical field

The utility model relates to the roll body of producing the used drawing-off hot-rolling of chemical fibre, a kind of efficient hot-rolling roll body of more specifically saying so.

Background technology

Producing in the process of chemical fibres such as polypropylene fibre, terylene, polyamide fibre with melt spinning method, the drawing-off hot-rolling is the most important equipment parts, and the height of drawing-off hot-rolling quality and the quality of performance directly have influence on the quality of chemical fibre.General drawing-off hot-rolling, comprise by bearing and be contained in the roller seat on the motor shaft and be packed in the roll body at position, motor shaft outer end, the heating element heater of heating roll body is housed in the cavity that roller seat and roll body surrounded, temperature sensor is housed on roll body, heating element heater is connected with temperature control equipment with temperature sensor, and roll body is that the sidewall of steel formula structure and roll body is solid.In the production process, roll body is at a high speed rotation under the drive of motor, and chemical fibre is wrapped in and is heated on the outer surface of roll body and carries out drawing-off.This sidewall is the roll body of solid construction, has following deficiency; 1, if the roll body sidewall is too thick, though thermal capacity is big, be easy to the thermostatic control to roll body, increased the weight and the rotary inertia of roll body thereupon, power consumption is excessive in rotation process; 2, if with the attenuation of roll body sidewall, though power consumption is few in rotation process, but it is too little to have thermal capacity, is difficult for the thermostatic control of realization to roll body.Because general roll body has above-mentioned deficiency, the temperature fluctuation on roll body surface for a long time can only be controlled at ± 3 ℃ scope in, can not realize producing the desired roll body surface temperature fluctuation of high-quality chemical fibre at ± 1 ℃ index request.

Summary of the invention

The purpose of this utility model provide a kind of power consumption less, be easy to the efficient hot-rolling roll body of control roll surface temperature.

In order to realize above-mentioned purpose, this efficient hot-rolling roll body, its design feature is that the interior at roll body is provided with fluid chamber, and the big liquid of thermal capacity is housed in the fluid chamber.

Above-mentioned fluid chamber can be and the corresponding big annulated column of the shape of sidewall chamber, also can be axial, the equally distributed a plurality of little fluid chamber in interval, each little fluid chamber can be cylindrical, the shape that also can be other, as cube shaped, make for convenient, fluid chamber is the equally distributed a plurality of cylindrical little fluid chamber in interval preferably.

The liquid that above-mentioned thermal capacity is big otherwise have corrosivity and thermal stability will be got well, the liquid that meets this requirement comprises water and oil, preferably water.

The interior of efficient hot-rolling roll body described in the utility model is provided with fluid chamber, the big liquid of thermal capacity is housed in the fluid chamber, its beneficial effect is: 1, energy-conservation, because the proportion of liquid medium is much smaller than the proportion of hot-rolling roll body material, therefore alleviated the weight of hot-rolling roll body, reduced its rotary inertia, obvious energy conservation when high speed rotating; 2, improved the temperature control precision of hot-rolling, because the thermal capacity of liquid medium is the several times of hot-rolling roll body material, therefore the thermal capacity of whole hot-rolling roll body obviously improves, thereby increased the comprehensive thermal inertia of hot-rolling roll body, adopt same temperature control system, can be in ± 1 ℃ scope with the roll body surface temperature control.

Description of drawings

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, wherein:

Fig. 1 is the structural representation of the described efficient hot-rolling roll body of embodiment;

Fig. 2 is the schematic cross-section of fluid chamber efficient hot-rolling roll body when selecting for use with the corresponding big annulated column of the shape of sidewall;

Fig. 3 is that fluid chamber is selected for use axially, the schematic cross-section of efficient hot-rolling roll body during equally distributed a plurality of small cylindrical at interval.

Among the figure, 1 is the roll body sidewall, and 2 is fluid chamber, and 3 is liquid medium.

The specific embodiment

With reference to accompanying drawing, the described efficient hot-rolling roll body of present embodiment, 320 millimeters of length, 190 millimeters of external diameters, 150 millimeters of internal diameters, sidewall 1 inner shaft of roll body to, evenly to get out 35 diameters at interval be 10 millimeters slotted hole, each slotted hole is as fluid chamber 2, the big liquid of thermal capacity 3 is housed in the fluid chamber 2, and liquid 3 is selected pure water for use.After each fluid chamber fills with water, with the method sealing water filling port of welding, make efficient hot-rolling roll body again.The described efficient hot-rolling roll body of present embodiment, roll body weight saving 17.2%, energy-conservationly surpass 17.3%, because the ratio of heat capacities steel of water are big 40 times, thereby make the comprehensive thermal inertia of hot-rolling roll body increase 2.05 times, adopt same temperature control system, can be in ± 1 ℃ scope with the roll body surface temperature control.Use the described hot-rolling roll body of present embodiment, can produce high-quality, high performance chemical fibre fully.
