CENTRIFUGE CONTINUOUS ACTION

It was announced on October 26, 1935, No. 179007

Published in the "Bulletin of inventions and trademarks N" 19 for 1964.

Known centrifuges, periodically loaded and unloaded on the go, as well as continuously operating, are equipped with mechanisms for advancing and unloading the fugible material on the go. The complexity of these crucial mechanisms makes it difficult to manufacture centrifuges and, moreover, lonasty, augers, scrapers, etc., employees transfer the product, grind it, which in some cases is completely unacceptable.

The proposed continuous centrifuge is designed without mechanisms for advancing or unloading the hemmed material.

Promotion of the fugue material along the centrifuge forming the drum, carrying the sieve or filtering surfaces, is achieved by the fact that the latter are made simultaneously with the rotational oscillatory movement, directed along the rotation axis of the centrifuge.

FIG. 1 shows a centrifuge in the Bertschalyum section, in which the drum is fixed on an elastic bottom; in fig. 2 - the same, the drum is fixed on the spring; in fig. 3 - the same, the drum is fixed on the springs.

The centrifuge (Figs. 1, 2, 3) consists of a conical or cylindrical rotating drum 1, provided with screens or filtering surfaces 2, which communicate a fast oscillating movement (vibration) directed along the axis of rotation of the drum. When the side walls are inclined, the angle of inclination should be less in Gosplan when the SNK of the USSR

the angle of friction of the product on the side walls of the drum, so that the fugible product, in the absence of vibration of the sieves, is not produced by the centrifugal force.

When the sieves vibrate along the axis of rotation, the fuguel product will move along the gradient of the drum steppes (along the formation) with a speed depending on the amplitude and frequency of the oscillations. With a cylindrical drum, the fugum product will also move along the drum core by equalizing the thickness of the product layer between the loading point and the discharge side of the centrifuge.

To enable oscillations of sieves along the axis of rotation, a zeitriff) in whole, or only its outer drum, is fixed on the main shaft 5 on the unrug: roll - moving p, the length of the axis of rotation.

Other rolls of the drum of the drum 1trnfugs on the main shaft 3 can be made with any known technique; Unrugom 4 (fig. 1), on a cruciform nli star-shaped spring 5 (fng. 2), or on coil springs 6 ((|: sp. 3) n. n.

Axial oscillations of the drum Y, or the centrifuge as a whole, can be excited by any known enoco6o; i. One of the possible ways to remove excited fluctuations is shown on a diagram. 1. Two or more electromagnets are stationary or rotating with the drum ;, or two or more electromagnets under the centrifuge; 7. When the electromagnets are unblemished or intermittent, the alternating magnetizer will act on the magnetic masses of the bottom 4 of the center; . Electromagnetic magnets powered by direct current (or permanent magnets) will also excite vibrations if the central substance of the central arc is located at the outlet of the mass 8 of the magnetic substance, playing the role of core electromagites 7. The passage during rotation of the zeitrifuge near the poles of the fixed electromagite 7, masses 8 will receive and transmit centrifuge impulses that excite oscillations along the axis of rotation.

In the event of a movement along the axis of the crush, oscillations can also be transmitted to Barbayu 1 through the shaft, both in the case of hard and in the case of elastic fastening of the central centrifugal drum on it. The main shaft 3, installed in sliding supports or on other operas, oscillations can be communicated by any known mechanisms and methods. One or another method or mechanism for transmitting axial oscillations to the drum / carrying sieves or filtering surfaces 2 does not change the new principle of the proposed centrifuge and the characteristic distinguishing feature of its structure, just like one or another method or method of rotational motion.

In the proposed petrifuge, the material is slid along the forming screen, and not removed from the screen while shaking. This is achieved by vibrations of a type that is of the harder type, which in the shaking devices are side effects that do not affect the material's moving process, since these vibrations occur after the blow causing wind chivas when the material is already detached from the surface of the sieve.

Due to the fact that axial vibrations can be excited both continuously and periodically, the proposed centrifuge can operate both completely continuously and periodically, being unloaded and loaded during the run. This will greatly enhance the potential for its use.
