Abstract
The invention relates to a coal inlet device of a coal pyrolysis furnace. A hopper (2) is arranged below a spiral coal feeder (1), wherein the hopper (2) is connected with a rotary coal adder (3) through a flange; the rotary coal adder (3) is connected with a coal distributor (5); the coal distributor (5) is connected with 2-10 discharge pipes (8) through sleeves (7); a funnel plate (4) is arranged at the upper part in the coal distributor (5); a uniform distribution unit (6) is arranged below the funnel plate (4); a 45-degree elbow is arranged above each discharge pipe (8); and the lower end of each discharge pipe (8) is connected with a straight pipe (10) through a moving sleeve (9). By changing the rotation speed of the rotary coal adder, the coal adding amount and time can be accurately controlled; the coal feeding amount can be uniformly controlled through the distributor, thereby ensuring that all parts have the uniform coal amount; the 2-10 discharge pipes can simultaneously feed coal to a carbonization chamber; and the sleeve arranged at the lower end of each discharge can be demounted conveniently, thereby facilitating the replacement and maintenance.
Description
Technical field
The invention belongs to a kind of pit kiln, be specifically related to a kind of device for coal that advances of coal heat decomposition stove.
Background technology
The coking of the most of employing of pit kiln in the market intermittent type namely adds pit kiln to coal, draws off after refining is good, adds coal again.Be a hopper so advance device for coal, add coal just, can not produce continuously, more can not control at any time its coal input quantity.
Summary of the invention
Technical problem to be solved by this invention provides a kind of device for coal that advances of coal heat decomposition stove.Serially, provide quantitatively, at any time required coal.
Technical scheme of the present invention: a kind of coal heat decomposition stove advance device for coal, it comprises: spiral deliver coal device 1, hopper 2, rotation stoker 3, funnel plate 4, coal divider 5, divider 6, sleeve pipe 7, tremie pipe 8, moving casing 9, straight tube 10.The deliver coal below of device 1 of spiral is provided with hopper 2, and hopper 2 is connected with rotation stoker 3 by flange, and rotation stoker 3 is connected with coal divider 5, and coal divider 5 passes through sleeve pipe 7 and is connected with tremie pipe 8.Coal divider 5 inner and upper are provided with funnel plate 4, and the below of funnel plate 4 is provided with divider 6.Tremie pipe 8 tops are provided with 45 ° of elbows, and the lower end of tremie pipe 8 is connected with straight tube 10 by moving casing 9.Tremie pipe 8 is 2～10.
The present invention compared with prior art has following beneficial effect: owing to by the rotation stoker coal bunker is isolated into two portions, by the rotation stoker, the variation of speed of rotation can be controlled coal amount and time accurately; Can evenly control coal-supplying amount by divider, it is even to reach each several part coal amount; Tremie pipe is arranged to 2～10 can be for simultaneously coal supply of coking chamber, and the tremie pipe lower end is provided with moving casing can be for convenience detach, is convenient to change and maintenance.
