Description

Technical Field

[0001] The utility model relates to the technical field of combustion devices, in particular to a high-efficiency lean coal mixed with anthracite combustion device. Background Art

[0002] Lean coal refers to coal with low calorific value, which is generally between 4000 and 5000 kcal / kg. The coal quality is poor, and the ash and volatile matter are high, so it will emit black smoke when burning. Anthracite refers to coal of relatively high quality, with high carbon content, high calorific value, low ash and volatile matter, and will not emit black smoke when burning.

[0003] When the combustion device uses lean coal mixed with anthracite for operation, the two types of coal have different combustion efficiencies and therefore different utilization rates. The existing combustion device cannot effectively mix the lean coal and anthracite during feeding operation to make them evenly distributed. The uneven distribution of lean coal and anthracite in the combustion device can easily lead to incomplete combustion and substandard heat generation. In addition, the feeding of existing combustion devices is mostly done manually, which has poor operability. Utility Model Content

[0006] When using a high-efficiency lean coal mixed with anthracite combustion device in the technical solution, the lean coal and the anthracite are respectively introduced from the feeding ports on the front and rear end surfaces of the top barrel through the material guiding mechanism, and the two kinds of coal enter the mixing barrel after passing through the through ports respectively. After the feeding ratio is completed, the internal motor of the drive box is started to drive the top plate at the top of the mixing barrel to rotate, and the top plate drives the turntable to rotate through the electric telescopic rod. During the rotation of the turntable, the two kinds of coal are evenly mixed with the mixing rod. After the mixing is completed, the built-in motor of the side box is started to drive the internal screw rod to rotate, and the screw rod thread drives the slider to drive the mixing barrel to descend. The lower end of the mixing barrel passes through the feeding port and enters the interior of the combustion barrel, and then the electric telescopic rod is started to drive the turntable to descend, and the turntable is separated from the lower end opening of the mixing barrel. At this time, the two kinds of coal are discharged into the combustion barrel through the gap, and the residual coal can be discharged by the centrifugal force of the rotation of the turntable. The internal combustion is ignited through the operation port, and the smoke from the coal combustion is discharged through the exhaust pipe.

[0007] Preferably, a material outlet is provided in the middle of the upper end surface of the combustion cylinder, the lower end opening of the top cylinder corresponds to the material outlet, and the mixing cylinder is adapted to the material outlet. The material feeding operation is completed through the material outlet, and a material supply channel is reserved.

[0009] Preferably, sliders are fixed on both sides of the mixing cylinder, and the sliders are slidably installed in the corresponding side boxes. The mixing cylinder is slidably installed in the top cylinder through the cooperation of the sliders and the side boxes.

[0010] Preferably, a screw is rotatably mounted inside the side box, and the screw thread penetrates the corresponding slider. The screw is driven to rotate by the built-in motor of the top box, and the screw thread drives the slider to rise and fall.

[0011] Preferably, a top plate is rotatably mounted on the top of the mixing barrel, and the upper end of the electric telescopic rod is fixed on the top plate, and the output shaft of the motor in the driving box is connected to the rotating shaft of the top plate. The top plate is driven to rotate by the motor in the driving box, and the top plate drives the rotating disk to rotate through the electric telescopic rod.

[0012] Preferably, mixing rods are fixed on both sides of the upper end surface of the rotating disk. During the rotation of the rotating disk, the mixing rods cooperate to make the two types of coal in the mixing barrel mixed and distributed evenly.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the operator starts the device through an external control device when powered by an external power supply, and introduces the lean coal and the anthracite into the feed ports on the front and rear ends of the top barrel through the material guide mechanism, and the two kinds of coal enter the mixing barrel after passing through the through ports. After the feeding ratio is completed, the motor inside the driving box is started to drive the top plate at the top of the mixing barrel to rotate, and the top plate drives the turntable to rotate through the electric telescopic rod. During the rotation of the turntable, the mixing rod cooperates to make the two kinds of coal mixed evenly. After the mixing is completed, the built-in motor of the side box is started to drive the internal screw rod to rotate, and the screw rod thread drives the slider to mix The cylinder descends, and the lower end of the mixing cylinder passes through the feeding port and enters the combustion cylinder. Then the electric telescopic rod is started to drive the turntable to descend, and the turntable is separated from the lower end opening of the mixing cylinder. At this time, the two kinds of coal are discharged into the combustion cylinder through the gap. The residual coal can discharge the material by the centrifugal force of the rotating turntable.

It reduces manpower consumption and enhances its operability through automatic feeding and supply. At the same time, the added mixing mechanism mixes the lean coal and the anthracite to make them evenly distributed, thereby ensuring the subsequent combustion quality.
