Description

In the proposed device for loading milled and lump peat into the furnaces using pushers, the latter are located one above the other in the front wall of the bunker and are equipped with toothed racks for giving them reciprocating movements through the gear sectors associated with the crank-lever mechanism. The pusher guides of the pusher slides on the fingers, of which the lower ones are installed, on moving arcs moved to change the inclination of the pushers by turning them near the upper fixed fingers. At the bottom of the device is installed under the protective tiles of the hammer crusher, the fingers of which are elastically fastened to the sleeve, and under it is placed a grid with adjustable grates to lower the fuel into a chute of certain size.

The drawing shows a vertical section of the device for loading milling and-lump fuel into the furnaces.

In the front most, inclined wall / bunker, pushers 2 and 5 are located one above the other, mounted with their rocker cuts 23 and 22 on the guide pins / b, / 5 and 20, 21, of which fingers J8, 20 are fixed on the wall of the bunker, and fingers 19, 2J are placed on movable arcs 24, 25, having, a series of holes for mounting the arc on fixed axles 26, 27, fixed to the wall of the bunker. The pushers are equipped with toothed racks M, 15, which are in engagement with the toothed sectors 16, 17, the axes of which 33, 34 are connected by means of levers 31, 32 to the rod 30, pivotally attached to the shoulder of the cranked lever 28, mounted on a fixed support 29. The other arm, the lever 28, is associated with a crank mechanism 5 of motor 4, telling the recipients to reciprocate. The upper portion of the toothed sectors 16, 17 is circumferentially circumscribed from the centers of the fingers 18,20, with a radius equal to the distance from the centers of the fingers to the toothed rack, which allows the pushers to move in the longitudinal direction and change their inclination, turning around the stationary fingers 18 20 by moving arcs

 .

On the lower part of the opposite wall 6 of the bunker, the already known scraper conveyor 7 is placed, the chain 8 of which is provided with scrapers for feeding peat from top to bottom; the conveyor 7 can be raised by means of a block, and the flap 45 is lowered in its place.

At the bottom of the bunker, under protective slats 36, a hammermill is placed, the fingers 9 of which are elastically fastened to the sleeve 37. A grill 10 is installed under the crusher with adjustable grate bars for adjusting a certain size of fuel passed through the funnel 43 into the chute 11 to the firebox. ,,

Peat poured into the bunker and pressed by the weight of overlying layers to the pushers .2 and 5, when they move upward, will not follow them due to the fact that the overlying peat layers with their pressure prevent this, on the one hand, and, on the other, the ledge 35 of wall 7 will also delay the upward movement of peat; while chewing pushers 2 and 3, moving up, will free up space in front of their front walls 72 and 13. Peat, by virtue of pressure from above, will occupy the vacated space and will thus move down to the outlet a from the bunker and slowly moving Transporter 7 will pick up the peat pressed to it with its scrapers and will move it to the crusher. In the subsequent movement of pushers 2 and 5, but in the opposite direction, i.e. From top to bottom, the pushers, on the one hand, will push ahead the lying peat, which has just been poured, with its front pads 72 and 75, and on the other hand, the pressure of the overlying peat on the pushers 2 and 5. will create friction between their surface and the one lying on them. peat, as a result of which peat will be attracted to the pushers, moving with its entire mass lying on the pushers and in front of the sites 72 and 13.

Before entering the crusher, the peat will be perceived by protective strips 36, installed in case of the possibility of large pieces of peat falling and thereby preventing its clogging and stopping. Pieces of peat that have fallen on the protective strips 36 are first broken by fingers 9 and the already shredded peat enters the crusher and the subsequent blows finally collapse and enters through the grate 7 into the receiving trough 77. The grate is so arranged that it allows its separate grate to be moved apart and shifted than Peat crushing is regulated to the lowest possible.

In case of contact with peat in the bunker, and, consequently, in the crusher of iron parts, such as bolts, nuts, iron scraps, etc., they will be picked up by the fingers of the crusher 9 and carried away inside, without fingers, thanks to spring fixation they are on crusher 6 hub 37, and thrown upward, where iron parts fall into the box with electromagnet 5 (5, fixed under the fixed base 5P of the first pusher 5 from the bottom.

The door 40 serves to inspect the magnet and remove the iron parts attached to it. The doors 41 and 42 are used to observe the movement of peat through the grate 10 of the crusher. The work of the movable pushers, as well as of the conveyor, ensures that the bunkers prevent trapping the peat and forming arches from it in narrow places. , especially, in the outlet of the bunker. The use of the crusher allows to pour peat mixed (lumpy and milling) and purely lumpy peat into the bunker, at the same time producing pulverized fuel.
