Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that when the impeller feeder in the prior art is used in the coal-fired boiler slag discharge system, the feeder is prone to jamming due to the presence of dry slag with a large particle size, and further provides A feeder with a double-wheel structure that can eliminate the above-mentioned jamming phenomenon

Embodiment Construction

[0035] Such as figure 2 and image 3 As shown, the two-wheel feeder of the present invention includes a housing 1, a feed inlet 2 arranged at the top of the housing 1 and a discharge outlet 3 arranged at the bottom of the housing 1, and an outlet 3 arranged at the bottom of the housing 1. The feeding unit in the housing 1 and below the feeding port 2, and the driving device connected with the feeding unit, the driving device drives the feeding unit to rotate.

[0036] The feeding unit is composed of a first feeding impeller 10 and a second feeding impeller 11, the first feeding impeller 10 is parallel to the axis of the second feeding impeller 11 and the outer contour line 4 is tangent, the second One feeding impeller 10 and the second feeding impeller 11 all rotate downward toward the tangential position 9; round.

[0037] From Figure 5 It can be seen that the feeding impeller is composed of a central shaft 13, two circular sealing plates 14 and several blades 15, the bla...

Abstract

The invention discloses a dual-wheel feeding machine comprising a shell provided with a feed hole and a discharge hole, a feeding unit and a driving device, wherein the axis of the first feeding impeller and the second feeding impeller of the feeding unit are parallel and the outer contour lines thereof are tangent; and both the two feeding impellers rotate downwards towards the tangent position. When the dual wheel feeding machine adopting the structural style is used in the slagging system of a coal-fired boiler, even the large-granularity slag can be blocked between the first and the second feeding impeller blades, the large-granularity slag block can be extruded to the feeding impeller since small-granularity slag below the large-granularity slag can press the slag downwards to generate a storage space in the feeding impellers, therefore the blocking phenomenon of the feeding machine can be avoided.

Description

technical field [0001] The utility model belongs to the field of slag discharge equipment for coal-fired boilers, in particular to a double-wheel feeder. Background technique [0002] At present, most power stations are gradually adopting dry slag discharge system to discharge slag from coal-fired boilers. The dry slag discharge system generally uses a steel belt slag conveyor to transport the slag treated with crushed slag to a high-level slag bin or slag storehouse for subsequent transportation or direct discharge. In some practical engineering applications, since the slag bin or slag storage is far away from the coal-fired boiler, if a steel belt slag conveyor is directly installed to transport high-temperature slag, a very long steel belt slag conveyor needs to be installed , so the installation cost of the equipment is very high. In order to solve the above problems, a two-level conveying system is generally set up, that is, the high-temperature ash discharged from the...
