Description

The subject of the invention is a device for the manufacture of mass sawing and molding of slabs (mainly mineral cork) in pallets equipped with a bob ;;.; And walls on the conveyor, which pass through the drying chamber. These chambers are equipped with a shelf conveyor for advancing pallets with a drying material, a cassette pallet lifter located in front of the shelf conveyor, as well as a cassette reducer mounted along the axis of the conveyor, and a device for simultaneously pushing all the pallets raised by the cassette lifter onto the shelf conveyor.

In the drawing, schematically 1 shows a longitudinal vertical section of the dryer.

The dryer in the head has a dosing scale / for cotton wool, two belt conveyors 3 for uniformly feeding the cotton to the preparation 6. Two two dosing tanks 4 for emulsions are installed above the preparers 6.

To adjust the alternate pic; Dupleni wool on Tpaiicnoptery provides a flap 2.

Further movement of the material is made on the conveyor belt. The construction of this conveyor consists of two Gall chains, spaced 80 cm from each other. The length of each chain link is 52 cm. Metal pallets 5 with holes all over the surface are arranged in a checkerboard pattern between the Gall chains.

Two preparatory 6 hydromass in the head of the conveyor // are located in the bunker 5. Behind the bunker along the conveyor movement there are two scrapers 8 for leveling the mass and a roller 14 l.1 of its slight rolling down.

Water is sucked off by a suction filter / 5 connected by a pipeline with a wet vacuum pump (not shown on the drawing). On top of the suction filter there are two punches 16 for pressing the hydromass under the pressure of L at a pressure of not more than 0.1 kg / cm, which also play the role of surface vacuum curing and forms of hp plates.

No. 844012

At a distance of 4 m from the putch filter, a drying chamber 18, d, k9, a net lifter, 21 molded plates, a ten floor bracket J9 and a cassette roller 22 begins. a device for simultaneously pushing all lifted upraiser 2 / pallets onto the shelf conveyor. The fencing of the super chamber 18 is made of a mineral cork, mounted in a metal frame.

The main chain conveyor // has a tension station (not shown in the drawing) and is driven by a gearbox. Asterisks 10 and 17 for ueneii out. Nene in the form of a nestigrane. Back cooling: ne; daughter 17 --- water.

A roller conveyor 24 is installed with an asterisk / 7. Assigned: .- more than 1P1 for transporting finished slabs to the packaging workshop

In the end pillars of the drying chamber 18, otvergs are arranged for the passage of the main center, the conveyor belt and for supplying hot and suction of exhaust air. To inspect and repair the conveyor 19, the cassette lifter 21 and the cassette dispenser 22, there are warm doors.

The air required for drying is heated in a lamellar heater 25, and the air inlet and exhaustion of the axle .1 is used by Scirocco I-20 fans. The Shonn recycle system.

The dryer has an air flow stream (on the countercurrent), caused by wind, it is possible to have a low plate temperature at the end of the chamber and at the outlet, at which it is possible for workers to carry them.

Conveyor belts d; 1 feed of cotton wool 3, dosing mixer; The emulsion tanks 4, the needle drum of the preparation 6 and the scrapers 8 for leveling the hydromass in the form are driven to move from the electric motor through a special transmission.

Fans 13 and 20, like the vacuum pump, have their own electric motors.

Cassette notebinder 2 / and cassette downer 22 ig.nchot individual electric drives with a reducer.

The process of the dryer is as follows. The material (cotton) (6.5 kg) weighed on the dosing scale is poured onto a belt conveyor 5, which is fed to the preformer 6 of the hydromass. At one time or a little earlier, a diluted emulsion (approximately 75 liter (s)) is poured from this dispenser into this preparer after about 1 minute. A 10/1 solution of potash alum is poured into the hydromass (a mixture of cotton with an emulsion) in the amount of two liters. After another 1 min. the casing of preparation 6 is tilted, and the entire mass is poured into the hopper 5.

From the bunker 5, through the automatically opening latch 7, the mass enters the pallet laid on the main chain conveyor, where it is leveled by continuously moving skids 8. By subsequent movements of the conveyor, the mass enters first under the knife / 2 and then under the roller 14. After b min, the mass enters in gutch filter 15.

The suction of water occurs within 3 minutes 40 seconds due to the fact that the vacuum chamber has gab1) ity accommodating two plates. Simultaneously with the removal of moisture from the bottom, a light extrusion occurs and the moisture is sucked from above by starting 16. Two metal frames are fixed to the lower (working) part of the punch by the size of the slab dm controlling its dimensions.

With a further movement of the main conveyor, a pallet with a molded and somewhat dehydrated mass is fed into the drying chamber 18. Approaching the 2L cassette lifter, the pallet with thorium is picked up by an approached shelf and rises 30 cm. Such a lifting takes place every 2 minutes. and after all 10 shelves of elevator 21 are filled (which will happen in 20 minutes}, all 10 pallets with molded mass of ejector 23 collide on 10 shelves of shelf conveyor 19. On this conveyor, the pallet moves at a speed of 52 cm in 20 minutes (intermittent movement). Approach the cassette tape recorder 22 .. the pallet collides on its shelves and gradually intermittently moves 30 cm across 5 each 2 minutes to rest on the main conveyor chain II.

Upon leaving the drying chamber, the plate is separated from the pallet and removed by the workers on a roller conveyor 24. By the same workers, the pallet is fixed to the main conveyor chain with special hooks, which automatically release the pallet at the first approach under the suction filter.
