Description

Autoclave heating, cooling and wind circulating system device

Technical field

The utility model relates to the pressure vessel field, is specifically related to autoclave the heating of particularly big-and-middle-sized composite autoclave, cooling and wind circulating system device.

Background technology

Autoclave is that composite carries out hot-forming key equipment, the heating of existing autoclave, cooling and wind circulating system device, and its heating arrangement exists:

1, because heat bridge is more, autoclave rear end temperature is too high;

2, install the comparison difficulty, because electrothermal tube quantity is more, therefore install the comparison difficulty in the sealing of electrothermal tube and tank body, on-the-spot problem is more; Because motor shaft works under high-temperature condition for a long time, the motor shaft temperature is easy to raise, and autoclave rear end temperature is also constantly raise, and can have a negative impact to the steady operation of motor.

Existing autoclave generally is directly cooler to be cooled off by cooling water, just only be connected with a cooling water valve in the cooler bottom, open cooling water valve, cooling water directly enters in the cooler, coil pipe is cooled off, because autoclave intercooler temperature is very high,, exist to cause cooler to break easily when cooling water directly injects in the cooler; The wind-guiding heap has the wind of part to pass through from B, C-channel, forms a little wind circulation, and the existence operation is uneconomical, the defective that wastes energy, and after temperature in the autoclave raise, cooling tube may make cooler that the defective of destruction is arranged owing to expand with heat and contract with cold and can be out of shape.

The encapsulant of electrothermal tube is to be filled between electric heating tube and the electrical heating base, rely on the side of encapsulant to realize sealing, can make assembling difficult like this, and sealing is not fine, and the aft bulkhead thickness of heating pipe holder is thicker, and exposes the rear end at heat-insulation layer, the volume that is heated is big, have the case temperature height, packed density is not tight, defectives such as waste thermal source; Cooler generally, tube sheet when design thickness is bigger, has increased the weight of cooler, in carrying, installs the defective that a lot of inconvenience are also arranged.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, and is easy to install, energy savings, and long service life, machine operation is stable, autoclave heating, cooling and the wind circulating system device of low cost of manufacture.

In order to overcome the deficiencies in the prior art, the technical solution of the utility model is this auspicious solution: a kind of autoclave heating, cooling and wind circulating system device, comprise the autoclave housing, its special character is to weld tank flange on the autoclave housing, motor flange is connected with excessive flange, the tank flange inner chamber is equipped with cooling jacket, the circulated air impeller is housed on the motor, the transition air duct is connected with tank flange by bolt, gas deflector cone and transition air duct form matched in clearance, gas deflector cone is connected with electric heater, electric heater is connected with cooler, have valve to control cooling water on the annular tubesheet of cooler, guide rail connects cooler in the tank body by being welded on, on the cooler, the bottom connects valve.

The utility model compared with prior art has simple in structurely, easy to use, adopts recirculated water cooling motor shaft, can improve the motor service condition, makes the motor operate as normal, reduces autoclave rear end temperature simultaneously, prolongs the motor characteristics in service life; Structure to wind-guiding heap and transition air duct is improved, and specifically is B, the C-channel that removes wind.On the transition air duct, add deep bead, the rear end of wind-guiding heap directly closely contacts on deep bead, no short circuit wind passes the transition air duct, economical operation, the characteristics that do not waste energy, replace encapsulant with sealing ring, good airproof performance reduces the heating surface that exposes outside heat-insulation layer, has reduced the surface temperature of housing, structure tube list assembles simple; Cooling tube is because the distortion that produces of expanding with heat and contract with cold leaves movable space.When cooling tube generation heat expansion, upper perforated plate can move up, otherwise then move down, the too tightly or too pine that the tightness of bolt and nut can not be twisted should be able to make upper perforated plate that movable leeway is arranged, and increases the compression area of tube sheet, the tube sheet unit are is stressed to be reduced, not yielding, and the thickness of tube sheet reduces the quality of minimizing cooler; Pre-cooled by to cooler, prevent that chiller temperature is too high, directly inject cooling water to cooler under hot conditions, chiller temperature is easy to generate hurried variation, cause cooler to break, this improvement has reduced the temperature of autoclave intercooler, has prolonged the service life of cooler, has saved expense and cost to enterprise, have simple in structure, characteristics easy to use, that cost is low are widely used in high-end technology industry such as Aeronautics and Astronautics, electronics.
