SU42528A1 - Device for drying bards - Google Patents

Description

The main disadvantage of most of the bard drying methods that have been proposed is the high cost and deterioration of the product quality, also in the case when they use direct heating of bards with flue gases to reduce the cost.

In the device, which is our subject matter of this author's certificate, it is proposed to use heat of steam and reduce heat of flue gases by means of an intermediate transmitter, so that the quality of the product does not suffer.

The accompanying drawing shows both the scheme of the entire installation as a whole and individual devices, namely: FIG. 1 shows the general scheme of the installation; FIG. 2 and 3-dryer in transverse and longitudinal sections; FIG. 4 — a device for moving and distributing bards in a dryer; FIG. 5 and 6-evaporating oven in transverse and longitudinal sections; FIG. 7-section through burs with heating pipes placed in it; FIG. 8-gate; FIG. 9-variant of the evaporator cabinet.

The bard from the distillery enters tank 1 (Fig. 1), equipped with a stirrer, from where it passes through pipe 2 to a continuously operating centrofuge 3, where it is separated into a solid and liquid part. The hard part, the so-called pellet, through the funnel 4 and the screws 5 enters the three-cylinder drying apparatus 6, the device of which will be described in detail below.

Separated centrifugal fluid through pipe 7 passes into the chute 8 located above the tank 9, located 1 above the evaporator box, in which zigzag batteries 10 are placed; 11- a centrifugal pump transferring the liquid condensed in the evaporator to a spare tank 13, from which it passes through the pipe 14 towards the hot air going to the nozzles 15 located in the two upper cylinders of the drying apparatus for spraying; 16 inputs of that pair into the double bottom space of the tank 1 for heating bards; 17-pipe through which steam enters the double bottom space of the tank 13; 18-pipe, diverting it into the double bottom space of the tank 9, located above the evaporating cabinet; 19-pipe on which steam

enters the radiator, heating the air; 20-pipe for condensate drainage; 21-at mock, from which cold air enters the radiator; 22 — A fan sucking hot air from a radiator, directed through pipe 23 into a firing heater 24 for overheating, from which superheated air leaves through pipe 25, spreads through manifold 26 through evaporator chambers and is directed through pipe 27 upper cylinders of the apparatus, from which exhaust air is removed through pipe 29; 28 spigot nozzles for adjusting the amount of air; A 30 pipe through which hot oil from a special hog enters the batteries of the evaporator box; 31-tube through which the oil enters the vertical part of the heater to restore the desired temperature; A 32-pipe supplying oil from the heater to the cylinder shirts of the drying apparatus, from which it exits through the pipe 33; 34 pump for forced circulation of oil; A 35-pipe through which the oil is returned back to a special bore; 36-cyclone at the exit of the exhaust air from the lower cylinder of the essential apparatus; 37 air exhaust pipe; 38-extender for oil when the last of the heater is left (the second one should be supplied when it leaves the special hog); 39-smoke pipe heater; A 40-shaped pipe to remove the exhaust air.

FIG. 2 and 3 the drying apparatus is shown in longitudinal and transverse sections. The tube 41, through which the mass enters the upper drum of the apparatus, has a regulating drum with blades for breaking up the mass; in the underlying drums mass passes through the pipes 42 and the finished product goes through the pipe 43, which also has a regulating drum; 44-shafts mixing mechanisms; 45 nozzles spraying liquid towards the outgoing air; 46-second bottom, enveloping half the cylinder for an oil hog; 47-the third bottom of the two lower cylinders for heating the air, heating the lower cylinder; the letter a indicates the place where air enters the bottom of the middle cylinder, the letter in-place where the heated air enters inside the lower cylinder; 48 tubes through which heated air from the middle apparatus enters under the bottom bottom.

FIG. 4 depicts a three-pointed beat (such beats in the required amount are fixed on the shaft 44); at one end of which there is a blade 49, having the form of a wide knife, the purpose of which is to advance the mass at a speed depending on the angle at which it is delivered; 50- bucket spreading mass; 51 scraper preventing the mass from sticking to the cylinder walls.

FIG. 5 and 6 depict an evaporating chamber, in which: a 9-tank for the mass to be evacuated, leaving it through the valve 53 into the funnels 54; 10 zigzag battery; 56-zholob under it; 57 doors for pipe cleaning; 58 and 59 holes, through which air enters the cabinet; 60 chimneys; 8-, a chute for distributing liquid to the chambers of the tank 9; A 62-hole pipe, by means of which the liquid is distributed by separate streams along the upper part of the spiral, due to which, falling down, it is gradually washing all the pipes of the spiral, which are in the same vertical plane; 63-distribution pipe for air; 64-pipe with valve, supplying air to the inside of the evaporating cabinet.

From this description, it is clear that the liquid, falling down, washes the pipes filled with hot oil and, moreover, comes into contact with the hot air coming towards it. To descale the pipes during continuous operation, one of the chambers is turned off with a corresponding separation of the upper tank, so that five chambers or ten spiral batteries are continuously operated.

FIG. 7 shows the plan of the hog: 65- the wall of the main hog; 66-wall of a special hog, attached perpendicular to the main one; 67 partition inside it; The 68-system of pipes consisting of separate frames is similar to that in the vertical part.

air heater; 69-valve; 70 chimney.

FIG. 8 shows a gate, due to the triangular cut of which, it is possible at any moment to pass a part of the gases directly into the pipe, which is controlled by a counterweight.

FIG. 9 shows a variant of an evaporation cabinet in which zigzag pipes with hot oil are removed; instead, frames are inserted having shelves with small sides, between which there are gaps. 63- pipe for hot air inlet; 71-frames with shelves arranged horizontally horizontally one above the other, so that the slots of the overlying frame should fall over the middle of the shelf below; 72 rods with handles and threads, which open the holes 73 in the bottom of the barda tank to distribute the latter to the upper frame; 74 pipes for exhaust air. It is clear from the drawing that the bard from the upper tank through the holes 73 should fall onto the upper frame underneath, from where through the slots in the form of a waterfall on the shelves of the underlying second frame, etc. The air, the entrance to the holes in the pipe 75, first than to get into pipes 74 leading to it, it must pass through the curtain of falling liquid several times in the same way as the water passes through the steam coming out of the vacuum apparatus in a barometric condenser. The more the above mentioned frames are delivered and the more often they are delivered, the longer the process of falling liquid will be and the fuller the air will be saturated with vapor.
