Refuse derived fuel rotary wind-locking loading and unloading device and method

Abstract

The invention relates to a refuse derived fuel rotary wind-locking loading and unloading device and a method. The device mainly comprises a hopper, a cylinder, a rotor and a driving motor, wherein the cylinder is horizontally placed, the hopper is arranged above the cylinder and is perpendicular to the cylinder, the rotor and the cylinder are arranged in parallel in the cylinder and one end of a rotor rotating shaft is connected with the driving motor. A plurality of blades are arranged on the rotor. Partitioned independent rotary material storage spaces are formed among the blades and the inner wall of the cylinder. A feed inlet which is matched with the discharge end of the hopper is arranged on the wall surface of the cylinder corresponding to each rotary material storage space. A wind inlet and a discharge outlet are arranged along the horizontal direction of each rotary material storage space, wherein the cross section of the wind inlet is smaller than the cross section of the discharge outlet. By adopting the device and the method, materials are fed from the top and are discharged from the side part and the material feed and discharge spaces are comprehensively utilized; the partitioned chambers formed by the blades and the cylinder rotate to realize wind-locking material storage and continuous metering, the structure is simple, the cost is low and the realization is easy; and since the materials are fed and discharged in a closed environment, the environmental friendliness is greatly improved.

Description

technical field [0001] The invention relates to a conveying device and method for garbage-derived fuel, in particular to a rotary windlock loading and unloading device and method for garbage-derived fuel. Background technique [0002] The term "garbage-derived fuel" comes from Refuse Derived Flue (hereinafter referred to as RDF), literally translated as: fuel derived from garbage. Refuse-derived fuel (RDF) technology is a technology that turns waste into fuel through different processing procedures. The refuse-derived fuel (RDF) in the RDF joint storage can be used as an alternative fuel to be calcined in the kiln head burner, kiln tail calciner or pre-combustion chamber of the cement kiln system, and partially or completely replace the traditional coal used in the cement production process. Fuel, to achieve a higher fuel substitution rate, save traditional fossil fuels used in cement kilns. [0003] However, in the prior art, the general combustion facilities directly use...

Problems solved by technology

[0003] However, in the prior art, the general combustion facilities directly use the belt conveyor to measure the broken garbage and send it to the combustion furnace, without continuous, stable and accurate measurement; especially because the garbage-derived fuel is light dust with broken flocs, it is transported by belt Machine transmission is not conducive to environmental protection, and the use of high-precision quantitative transmission devices such as rotor scales commonly used in cement production lines is easy to jam the transmission device, which is costly and not conducive to maintenance and maintenance
