Abstract
The utility model relates to a trough for preventing from attaching coal to a vibration coal feeder. The utility model is characterized in that a hot air trough which has a corresponding shape to the bottom of a coal trough is arranged between an original coal trough and a thrust plate, and the hot air trough is communicated with a hot air source through a hot air through hole on the top end of the hot air trough, so that the bottom of the coal trough can be heated, the moisture of partial coal which is contacted with the bottom of the coal trough can be reduced, and the purpose of preventing attaching can be obtained. The utility model has reasonable structural design; hot air from the secondary bellow of a boiler in an electric power plant can be used as a hot source, so that the trough of the vibration coal feeder can be operated safely and can save electric energy, and is a device for preventing attaching for troughs of vibration coal feeders at present.
Description
The utility model relates to the antiseized hopper of a kind of vibration feeder, especially for the antiseized hopper of power plant's pulverized coal preparation system electric and magnetic oscillation feeder.
The electric and magnetic oscillation feeder hopper that present power plant uses all is provided with antisticking device, inapplicable moist viscous material, because it is more to contain viscous material in the raw coal, add that raw coal adopts storage in open system, sleety weather raw coal water content is bigger, and flow resistance increases between coal and coal groove, make coal sticking more thick more on the coal groove, cause the powder process difficulty, power consumption increases, even has explosion of Coal Pulverizing System etc. to jeopardize the adverse consequences of safety and economic operation.
The purpose of this utility model is provided with antisticking device exactly on hopper, to overcome weak point of the prior art, provide a kind of vibration feeder antiseized hopper.
The purpose of this utility model is achieved in that between common vibration coal supply machine-made egg-shaped or honey-comb coal briquets groove and thrust plate and installs the hot blast groove additional that the hot blast groove is by hot blast through hole and boiler of power plant secondary air box hot blast UNICOM.That is hopper of the present utility model is a two-layer equation, the upper strata hopper is walked coal, lower floor's hopper leads to hot blast, and hot blast makes the coal drying with the heating of coal groove like this, reduce the surperficial moisture content of that part of coal that contacts with the coal groove, improve the temperature of coal supply groove and coal simultaneously, fundamentally reduced caking property, make the normal coal supply of vibration coal supply function, while hot blast and coal enter coal spout together dries coal, has prevented that again coal spout from gluing coal.
The utility model compared with prior art, owing to increased the hot blast groove of coal trench bottom, problems such as the sticking coal of coal groove, the sticking coal of coal spout and plugging have been solved, the normal powder process and the burning of boiler have been guaranteed, can economize on electricity in a large number, avoid explosion of Coal Pulverizing System, reduced operator's labour intensity, also reduced recondition expense simultaneously.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross section cut-away view of the present utility model.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: the utility model is made of coal groove (6), hot blast groove (4), thrust plate (3), hot blast through hole (2), hopper support (7), connecting hose (1).Coal groove (6) bottom surface is circular-arc, adopt the iron plate punch forming to be installed on the hopper support (7), coal groove (6) bottom is installed one and corresponding with coal groove (6) is circular-arc hot blast groove (4), this hot blast groove (4) also is fixed on the hopper support (7) by the iron plate punch forming, hot blast through hole (2) is positioned at the top of hot blast groove (4), by connecting hose (1) and hot air duct UNICOM, hot air duct and boiler of power plant secondary air box hot blast UNICOM.Thrust plate (3) is fixedly mounted on the bottom of hot blast groove (4), relies on the electric and magnetic oscillation mode to make thrust plate (3) drive hot blast groove (4) and coal groove (6) vibration.
Claims (5)
1, the antiseized hopper of a kind of vibration feeder comprises coal groove, thrust plate, it is characterized in that being equipped with between coal groove and the thrust plate hot blast groove, and the hot blast groove is by hot blast through hole and secondary air box hot blast UNICOM of power plant.
2, the antiseized hopper of vibration feeder according to claim 1 is characterized in that the coal groove bottom is circular-arc, and the hot blast groove that is installed in the coal trench bottom also is circular-arc.
3, the antiseized hopper of vibration feeder according to claim 1 is characterized in that thrust plate is fixedly mounted on the bottom of hot blast groove.
4, the antiseized hopper of vibration feeder according to claim 1 is characterized in that the hot blast through hole is positioned at the top of hot blast groove, by connecting hose and hot air duct UNICOM.
5, the antiseized hopper of vibration feeder according to claim 1 is characterized in that coal groove and hot blast groove by the iron plate punch forming, and is fixed on the hopper support.
