Description

Technical Field

[0001] The present invention relates to the technical field of coal blending, in particular to a raw coal bunker spiral bidirectional feeding multi-mode coal blending interconnection equipment. Background Art

[0002] The primary purpose of coal blending is to optimize the coal combustion process, improve coal combustion efficiency, and reduce fuel costs. Different coal-fired equipment has different requirements for coal quality. Coal blending can be used to adjust coal characteristics such as ash, sulfur, volatile matter, and calorific value to better meet the operating requirements of coal-fired equipment, ensuring safe and stable operation.

[0003] During the actual operation of the device, the coal in the raw coal bin is usually of different sizes. Oversized coal is very likely to get stuck in the transport channel during transportation, causing blockage in the feeding system. Undersized coal is pushed and subjected to friction by the spiral blades during transportation, and is easily crushed into overly fine coal under extrusion and shearing, and finally sticks to the transport channel or the spiral blades, resulting in reduced efficiency and increased risk of blockage.

[0004] Combining the above problems, it is found that it is difficult to avoid the above problems at the same time when using the existing equipment on the market, and even if it can be solved, it needs to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] First, the present invention utilizes a crushing unit, opens the top cover, and puts coal into the raw coal bin, and uses an electric gate door to prevent the coal from falling. When working, the first motor is started, the electric gate door is opened, and the coal falls into the crushing barrel, among which the coal smaller than the first screen will fall, and the coal larger than the first screen will be blocked. The second motor fixed with multiple fixed rods is started, and the crushing rods are driven by the rotation of the rotating shaft. The coal larger than the first screen is broken up by the interlacing of multiple layers of multiple crushing rods, and falls downward through the discharge hopper, which solves the problem that oversized coal is easily stuck in the transportation channel during transportation, causing blockage of the feeding system.

[0021] The dust collecting box is fixed with a clamping block and an inserting block, and the inner space of the dust collecting box can be opened by the handle on the dust collecting plate in the square groove on the back, so as to facilitate the transportation of coal powder. The gripping force is enhanced by the anti-slip coating, and the coal powder is stored in the dust collecting box through the dust collecting pipe of the vacuum cleaner. The dust collecting plate of the first dust collecting pipe of one of the vacuum cleaners is used to suck the over-fine coal generated during transportation in the conveying pipe or the smaller coal generated during the previous crushing into the vacuum cleaner through the second screen through the dust collecting port at the bottom, wherein the second screen prevents the moderate coal being transported from being sucked away together, and the dust collecting range is increased through the second dust collecting pipe of the other vacuum cleaner by the air diffuser of the connecting pipe, so as to suck away the coal powder that has not been crushed into smaller coal during operation of the crushing unit, thereby solving the problem that the over-small coal is pushed and frictionally acted upon by the spiral blades during transportation, and is easily crushed into over-fine coal under extrusion and shearing.

[0022] Third, the present invention utilizes a feeding mechanism, fixes the fixed frame through a connecting block, fixes the fixed block and the fixed frame together through a cross bolt, starts the third motor, drives the spiral blade to transport the coal through the screw rod of the output shaft, prevents the coal from leaking out of the limit groove on the surface of the discharge pipe through the limit block, fixes the support plate through the clamp, and uses the support plate as a base to support the electric stretching rod to push or retract the bottom block and the U-shaped groove. When two-way feeding is required, the electric stretching rod is started to take part of the coal through the U-shaped groove, and this part of the coal will be transported to another discharge pipe through the spiral blade. When excessive coal powder is stuck on the spiral blade or the inner wall of the conveying pipe is stuck with excessive coal powder, the cross bolt can be loosened and the spiral rod, spiral blade and limit block can be pulled out from the inside of the conveying pipe through the fixed block, which is convenient for disassembly and cleaning, thereby solving the problem that coal powder is easily stuck in the transport channel or on the spiral blade, resulting in reduced efficiency and increased risk of blockage.
