Abstract

The invention makes it possible to increase the economics by improving the blowing conditions and simplifying the cleaning of the grill and can be used in boiler units operating on solid fuel. The grate is formed by grate bars 1, installed with the formation of blowing slits between them and is equipped with a connecting rod 2 with a drive 3. Under the blow holes there are cleaning disks 5 placed on a common axis 6 and fastened with a mechanism 7 of their horizontal movement along the grid with simultaneous oscillation in the vertical plane. The mechanism 7 is connected to the drive 3 via a dial-up setting unit 5. The fixed guides 9 and the shuttle-movable guides 10 which interact with them are made with a sinusoidal profile are installed along the lattice. The output of the set point is connected to an electromagnet with a pusher. During the operation of the grate, during the stitching of the blow slits, a signal is sent to the electromagnet from the setter. From the drive 3, the movement is communicated to the disks 5. The disks 5 make longitudinal and at the same time lifting and lowering movements between the grate 1 and clean the blowing slits at the points of contact with the slag bed. The trajectory of movement of the discs allows frequent contact with the pinned surface without disturbing the technological layer of the slag pad, which allows to simplify the process of cleaning the grate, improve the blowing mode and increase the economical operation of the grate.

Claims (4)

Claim 1. The grate, formed by beam grates installed with the formation of a blast between them and equipped with a screwing bar with a drive, characterized in that, in order to increase efficiency by improving the blast mode and simplify cleaning, the grill is equipped with cleaning discs mounted on a common axis and fastened to the mechanism of their horizontal movement along the lattice with simultaneous oscillation in the vertical plane, with each disk placed under the blow gap. 2. Grill pop. 1, characterized in that the mechanism for moving the disks is connected through an additional drive for turning on the disks with the drive of the screwing bar. 3. The lattice in π. 1, characterized in that along the lattice in the zone of the extreme grates there are fixed guides and shuttle movable guides, the last of which are made mainly with a sinusoidal profile and the ability to interact with the fixed guides, while the disk movement mechanism is made in the form of two pivotally connected levers, one of which is connected to the drive, and the other is pivotally connected to the axis of the disks, equipped at the ends with rollers interacting with movable guides.
