Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The technical scheme combines the detailed description of the embodiments with the drawings. As shown in fig. 1-2, a biomass boiler slag conveying and collecting system comprises a slag outlet i 2, a lifting conveyor 3, a crusher 5 and an electromagnet 6, wherein a water pipe 4 is arranged at an upstream section of the lifting conveyor 3, spray heads 41 are arranged on the water pipe 4, and the nozzle direction of each spray head 41 faces to the inside of the lifting conveyor 3; the lowest end of the large-inclination-angle conveyor 7 is arranged at the downstream of the lifting conveyor 3, the highest end is arranged on a slag bin 11, and a gate 12 is fixed at the discharge opening of the slag bin 11; a conveyor cover 8 covers the large-inclination conveyor 7, a slag outlet II 81 is arranged at the upper end of the conveyor cover 8, and an ash discharge port 82 is arranged at the lower end of the conveyor cover; the ash chute 9 is disposed below the ash discharge port 82, the screw conveyor 10 is fixed to the ash chute 9 in an inclined manner, the belt conveyor 13 is disposed below the outlet of the screw conveyor 10, the belt conveyor 13 is received at the upstream end of the conveyor 14, the return conveyor 15 is disposed at the downstream end, and the downstream end of the return conveyor 15 is disposed above the lifting conveyor 3. The ash chute 9, the screw conveyor 10, the belt conveyor 13, the conveyor 14, and the return conveyor 15 constitute a slag return system in which the residue falls.

The lowest end of the large-inclination-angle conveyor 7 is hermetically connected with the downstream end of the lifting conveyor 3, and the crusher 5 and the electromagnet 6 are sequentially arranged between the lower end of the large-inclination-angle conveyor and the downstream end of the lifting conveyor. The slag is output to the lifting conveyor 3 through the slag outlet I2, and cooling water is sprayed out from each spray head 41 through the water pipe 4 to cool and remove dust from the slag. The slag is subjected to iron impurity removal operation under the action of the crusher 5 and the electromagnet 6. Thereafter, the slag is conveyed into a slag silo 11 by means of a large-inclination conveyor 7. Because the whole large-dip-angle conveyor 7 is covered with the conveyor cover 8, dust can be prevented from flying in the whole conveying link, and the slag falling in the conveying process can slide to the bottom of the large-dip-angle conveyor 7 and fall into the ash groove 9 through the ash discharge port 82, and under the action of the screw conveyor 10, the slag is returned to the lifting conveyor 3 again after sequentially passing through the belt conveyor 13, the conveyor 14 and the return conveyor 15, so that the residual falling slag is fully collected in the slag bin 11. In the slag conveying and collecting process, the process of manually conveying the slag to a warehouse is not needed, and the slag can be directly conveyed away by using an engineering vehicle only by opening the gate 12, so that the dust pollution is greatly reduced.

The ash chute 9 is an inverted conical space, the inlet of the screw conveyor 10 is positioned at the lowest end of the ash chute 9, and the outlet of the screw conveyor 10 is vertically downward. The gate 12 adopts an electro-hydraulic jaw gate to meet the ash discharge requirement. The middle portion of the conveyor cover 8 is fixed to a horizontal plane by a bracket 83 to improve the stability of the large-inclination conveyor 7.

The large-inclination conveyor 7 is further provided with a brush 71, and the brush 71 can contact with the lower bottom surface of the conveyor cover 8. During the operation of the conveyor, the brush 71 moves along with the belt, so that the brush 71 can clean the lower bottom surface of the conveyor cover 8, and slag is prevented from accumulating on the lower bottom surface of the conveyor cover 8.

In the present invention, unless otherwise specifically stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and can include, for example, fixed connections, detachable connections, or integral connections and can be communications between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
