Description

(54) AUTOCLAVE

one

The invention relates to special process equipment and can be used in enterprises for the molding, curing and gluing of products from composite materials and plastics, for example, in the aviation, shipbuilding and radio engineering industry.

An autoclave is known in which the required temperature is provided by electric heaters and fans located inside the autoclave flj.

The disadvantage of this autoclave is a small relative useful volume, since 5 heat exchangers and fans occupy a lot of space in it, and low efficiency, since a lot of energy is supplied for forced heating and cooling of all devices placed in the internal volume of the autoclave.

Closest to the proposed technical essence and the achieved result is an autoclave, comprising a housing with a lid, inside which

Placed screens and rotary mounted on the shaft with carrier discs heater G23.

A disadvantage of this device is the increased power consumption, especially with increasing pressure in the autoclave, since the rotors of the heater are connected to individual electric motors.

The purpose of the invention is to increase the efficiency of the autoclave by saving energy while increasing its heating rate.

The goal is achieved by the fact that in an autoclave for the treatment of products made, for example, from composite materials and plastics, comprising a housing with a lid, inside of which are placed screens and a rotary heater with carrier discs mounted on the shaft, the rotors are unequalized UN and coaxially mounted other holes, the through holes in the bearing disk of one of the rotors, the shaft is made with a removable part, equipped with a coupling with a thrust and mounted on the shaft with a rotor disk with through holes, while i keypad provided ispolnitelnym mechanism engaging clutch associated with it draft type and the screen associated with the clutch, it is movable. The drawing shows the proposed autoclave, longitudinal section. The autoclave consists of a horizontal cylindrical body 1, a locking lid 2, a working chamber 3, fixed screens 4 and 5, one screen 6 moving in the longitudinal direction, which form circulation channels 7 and 8 between themselves and the walls of the body 1 of the autoclave. the rear disc sits on the shaft 1O of the actuator 11, and the rotor 12, having through holes in the rear disc, on the shaft 13 of the bearing assembly 14, the shafts 1O and 13 being interconnected by a clutch 15, controlled by ciBOM tippers of the pushrods 16 from installed on the body 1 actuator The mechanism 17, and 9 with a clutch 15 and the bearing unit 14 are mounted in a common mounting sleeve 18. The autoclave works as follows. After loading the treated product into the working chamber 3 of the autoclave, its heating begins. In this case, both rotors work. For this. 5a actuator 11 is turned on, which by means of shaft 1O transmits rotation to rotor 9 and further through clutch 15, shaft 13 and bearing unit 14 to rotor 12, at that, actuator 17 by means of Tsirvi and pushers 16 moves movable screen 6 to its rightmost position by opening channel 8 for air circulation, and at the same time closes the clutch 15 of shafts 10 and 13. Thus, in this case, the entire heater unit is simultaneously working, and air circulation is performed under the action of revolvers through the corresponding recirculation ion channels; for rotor 12, air from working chamber 3 flows directly to it and then a part of it is rotated through channel 8 through channels 7 and again into working chamber 3; for rotor 9, air enters through openings in the rotor carrier disk 12, along bearing assembly 14 along sleeve 18 and, under the action of rotation of the rotor, is directed directly to channels 7 and further to the working chamber. Thus, the heater operates in the mode of heating to a certain working pressure of air inside it, which ensures the maximum rate of heating of the product at a given pressure. When the working pressure inside the autoclave is broken, which causes a change in air density and engine overload, the actuator 17 by means of a pull and a pusher 16 opens the clutch 15 of the shafts 10 and 13 and moves the movable screen 6 to the extreme left position, thereby closing channel 8 In this case, only rotor 9 is working at the set speeds. In the case of a repeated decrease in the pressure of the working medium in the autoclave, the actuator 17 is again activated and the heater operates with the entire unit, as in the original case. The proposed technical solution, providing a change in the power consumed for heating the gas stream with a change in the density of the gas, yields substantially. notable energy savings as the heating rate increases. The invention of an Autoclave, comprising a housing with a lid within which screens are placed and a rotary heater with a bearing disc mounted on a shaft, characterized in that, in order to increase the efficiency of the autoclave due to the economy of electric power, with an increase in its heating rate, the rotors are uneven and coaxial with each other, and through the holes in the bearing disk of one of the rotors, the shaft is made with a removable section fitted to the thrust coupling with a thrust and fixed to the shaft by a rotor disk with air holes, while the autoclave is equipped with an actuator, the clutch is connected with it, and the screen associated with the clutch is filled with a movable one.
