Description

In order to control the rotational speed of the proposed mixer, depending on the QT steam pressure in the boiler, its perforated buckets are mounted on the ends of the rods, which are rotated around a common screw with a screw that is located outside the boiler and rotates at a speed that are rheostatted with a contact on the disk. The latter is rotated in one direction or another. From the friction disks on the worm shaft, which can receive translational motion under the influence of a lever, I connected with a piston which is under the action of pressure in the boiler and two springs. /

The drawing shows schematically the boiler, equipped with the proposed bag.

Inside the boiler there are buckets B, placed on the ends of rods, which are set in rotation about i of the common axis of the screw b. The latter is located outside the boiler on the same shaft with the friction disk 8 and D and receives rotational movement from the electric motor G, whose rotational ciiopocTb is governed by a rheostat G with a contact on the disk E. The latter is rotated to the other side of the other disks D, which can progressively move

under the influence of the lever associated with the piston 3. The piston 3 moves in the cylinder, communicating through the tube I with the boiler, and is under the action of springs E, L.

As the steam flow rate increases, the pressure in the katle drops, which causes the piston 3 under pressure from the springs And drops, dragging behind itself a lever connected to the disks D, which at the same time move along the shaft axis to the right and "5) turn the disk E with a brush over the contacts of the rheostat G ; the resistance of the reactor is reduced, and the motor, and hence the agitator, begin to rotate faster, which should increase the vaporization. At low steam consumption, the opposite effect occurs: the pressure in the boiler D) 1 moves and pushes the piston 3, as a result of which the second disk D touches the E disk and the rotation direction of the E disk 1 changes, causing the resistance of the rheostat to increase and the motor with the whole; the system rotates more slowly than the vaporization slows down. In case, if the pressure i of the steam still exceeds the maximum allowable, the end of the piston rod opens the switch to the electric motor circuit and the stirrer stops rotating.

The subject of the patent.

Mixer for steam boilers or accumulators, characterized using perforated buckets B, planted: At the ends of the rods, driven into rotation around a common axis by a screw B, located outside the boiler, the speed of rotation of which screw is controlled by the action of a rheostat G with a contact on disk i driven into rotation on that. or inu1o side using friction discs D, receiving rotational motion from, on which the worm sits to B, a. translational motion - by the action of a lever connected to the piston.
