Abstract
The utility model discloses a boiler pulverized coal separation and feeding device, which comprises a boiler body and a conveyor belt. A feed hopper is arranged on the boiler body. The boiler pulverized coal separation and feeding device is characterized in that a rotary drum screen is arranged parallel to the upper face of the lower end of the conveyor belt, a stoking hopper is arranged at the upper end of the rotary drum screen, a receiving pipe is arranged at the lower end of the rotary drum screen, and a puller trolley is arranged below the receiving pipe. During feeding, pulverized coal is manually conveyed into the stroking hopper, the pulverized coal separated by the rotary drum screen falls on the conveyor belt and is conveyed to the feed hopper and then into a boiler hearth through the conveyor belt, coal particles fall into the puller trolley from the lower end of the rotary drum screen to be reused after being crushed. The pulverized coal entering the boiler hearth has no coal particles, and combustion is uniform, thereby saving energy and reducing consumption. The boiler pulverized coal separation and feeding device solves the technical problem of energy waste in the prior art.
Description
Technical field the utility model belongs to the boiler technology field, relates to a kind of boiler coal-ash and separates feeding device.
The boiler coal-ash feeding device of background technology prior art comprises body of heater and conveyer belt, and body of heater is provided with coal feeding bucket.During material loading,, be sent to coal feeding bucket through conveyer belt then and add in the burner hearth by manually coal dust being delivered on the conveyer belt.Owing to contain a large amount of particle coal cinders in the coal dust, enter burner hearth and can occur firing non-burn-through problem, cause energy waste.
Utility model content the purpose of this utility model is to solve the technical problem that there is energy waste in prior art, provides a kind of boiler coal-ash to separate feeding device.
To achieve these goals, the utility model boiler coal-ash separates feeding device, is to improve realization on the basis of existing technology, comprises body of heater and conveyer belt, and body of heater is provided with coal feeding bucket; Its main points are parallel rotary screens that are provided with above the lower end of conveyer belt, and the upper end of rotary screen is provided with and adds coal bunker, and the lower end of rotary screen is provided with material receiving tube, are provided with below the material receiving tube and draw truck.
During material loading, add in the coal bunker by manually coal dust being delivered to, separate through rotary screen, coal dust falls on the conveyer belt, is sent to coal feeding bucket through conveyer belt and adds in the burner hearth; The particle coal cinder falls into from the lower end of rotary screen and draws truck, uses after crushed again.Since enter the coal dust in the burner hearth, no particle coal cinder, so it is burning is evenly, energy-saving and cost-reducing.The utility model has solved the technical problem that there is energy waste in prior art.
Appended drawings is the utility model schematic diagram.
The specific embodiment with reference to the accompanying drawings, the utility model comprises body of heater 1 and conveyer belt 3, body of heater is provided with coal feeding bucket 2; The parallel rotary screen 5 that is provided with above the lower end of conveyer belt, the upper end of rotary screen 5 is provided with and adds coal bunker 4, and the lower end of rotary screen 5 is provided with material receiving tube 6, is provided with below the material receiving tube 6 and draws truck 7.
