CS199809B1 - Device for conveying dried loose material out of continuous drier - Google Patents

Abstract

An apparatus for extracting dry material from a once-through drier fitted with a hopper outlet and a tilting tray beneath it, has an oscillating plate mounted below the outlet and connected to a crank drive having a variable amplitude. Specif., the max. angle of tilt of the plate is adjusted to be less than the angle of repose of the material. A single cranked drive mechanism, combined with a connecting rod, may operate a number of hopper discharges.

The object of the invention is to achieve the discharge of the dried material at a constant density of the material column in the dryer * which allows optimum utilization of the capacity for the gentle handling of the dried material. of the invention insensitive to oizi has been incorporated, which substantially reduces the possibility of malfunctions in its operation.

According to the invention, this object is achieved by a device which consists in that a pendulum pawl is provided at a distance below the spout orifice. that the swinging bald is alternately inclined around the pin and its angle of inclination is less than the angle of repose of the dried material

The main advantages of the device according to the invention are that the discharge of the dried material from the outlet results in a constant density of the material * which is above the outlet opening * which allows optimum capacity utilization of the through drier. to damage it · In addition, there are no objects such as stones * metal parts etc. * contained in the dried material *, which significantly reduces the failure rate of the operation ·

The invention is explained in more detail below with reference to the accompanying drawing, in which: FIG. 1 shows a device according to the invention in longitudinal section, but without drive * in FIG. Fig. 4 shows a detail of the device in the location V of Fig. 2 * in Fig. 5, a device for discharging when emptying a through-air dryer, and Fig. 6 shows a crank drive of several adjacent discharging devices.

Below the funnel-shaped outlet 1 of the shaft drier, a pendulum-shaped swinging g is arranged at a distance д · The distance д of the sheet metal g from the bottom edge of the outlet opening 2 is determined by the longitudinal sides of the rocking skin g are provided with a chamfer 2 * 2I * which is directed towards the outlet X · The rocking plate g is rigidly connected to the pin g, which, for example in the embodiment of FIG. In the rocker arm 2 are arranged holes X2 · Ojaic · Xg of the crankshaft XX is by means of an articulated pin gg, articulated to the rocker arm 2 and a crank Xži. * it is possible to adjust the amplitude g of the swing plate 2 and hence the angle of inclination · Outside this adjustment possibility, the pin Xg of the overhung crank X2 can also be adjusted radially ·

If several outlets χ * Xj * 1 ”are arranged next to each other. AND*. 2 * iZt * - '· * · are connected to each other by a connecting rod Xg ·'

Upon actuation of the swinging skin 2, the dried material g is transferred from the outlet opening g to the swinging plate g and is rolled outwardly with respect to its inclined position.

Since the inclination angle is smaller than the angle ^yp Nu sušenóta mater ^heehaw lu g is deficient, ^t ane dried mater ^ial g of ^p res en ZKO ^with 7 ^and the swing plate * At the same time, as shown in FIG. 3, the hopper edge 17 compresses the dried material which is on the other half of the pivot plate 2, thereby accumulating 1g of dried material g on the upward half of the pivot plate 2. The accumulation 18 remains on the layer of dried material on the pivot plate g in the opposite direction. This changes the natural flow angle of the dried material g of the pivot plate g, thus ^á minders to OTE. ^{4 and} itself Rafe ₉ 18 * ^and accumulated from ^D sUouzne of ^profiles sm ^ decisive. olovin kaného ^{p y p} i Lech »buildup. lg, 18 * ^also will answer D, ^{and T} ed ^yl Omu množsl; ^ ^{characterized} in that pus ^three for one oscillation swinging plate g.

From the above, it can be seen that the device for discharging the dried material according to the invention operates with volumetric dosing. The amount to be discharged per unit of time is dependent on the frequency and amplitude of 2 oscillations of the rocker g. The quantity of material discharged increases if the angle of inclination of the rocker g reaches the value of the bulk angle of the dried material g. than the angle of repose of the dried material g, the dried material g does not fall out of the discharge device. -. If the through-flow cleaner is to be emptied exceptionally, the angle of inclination of the rocker plate g is greater than that of the material to be dried g, as shown in FIG. 5, and the crankshaft drive mechanism 14 is switched off when. when the rocker plate g is in an inclined position.
