Description

Technical Field

[0001] The present invention relates to the field of hybrid fuel power generation devices, and specifically to a process for generating electricity using a hybrid fuel made from sewage treatment plant sludge and mushroom residue. Background Art

[0002] A hybrid fuel power generation device is a power generation system that uses a mixture of multiple fuels. This type of device can improve power generation efficiency, reduce carbon emissions, and utilize multiple energy sources.

[0003] A specific existing process for generating electricity using sewage treatment plant sludge and mushroom residue to make a hybrid fuel can refer to a printing and dyeing sludge hybrid fuel preparation device with the application number: CN202420960342.7, which includes an auxiliary material feeding module, a screening module located below it, a feeding module at the discharge end of the screening module, a mixing module, and a sludge feeding module. The discharge ends of the feeding module and the sludge feeding module are both connected to the inside of the mixing module. In the present invention, sludge is directly transported to the mixing module through the sludge feeding module, and at the same time, auxiliary materials are fed into the auxiliary material feeding module. After being screened by the screening module, the materials are fed into the mixing module through the feeding module for mixing. After the mixing module fully mixes the two materials, it directly discharges to form a printing and dyeing sludge hybrid fuel. This process realizes integrated production and significantly improves work efficiency;

[0004] The above-mentioned device does not have a component for cutting after mixing. When it is necessary to discharge the mixed sludge and mushroom residue during use, the existing device cannot cut the mixed hybrid fuel. As a result, when discharging the fuel, the length is generally too long. During later use, the fuel with too long a length is extremely prone to incomplete combustion compared to the relatively short fuel. Therefore, in view of the above problems, a process for generating electricity using sewage treatment plant sludge and mushroom residue to make a hybrid fuel is proposed. Summary of the Invention

When the first fixing block 15 rotates, it drives the auger 19 to rotate along the inside of the sleeve 20, so as to drive the sludge and mushroom residue at the bottom end inside the mixing box 3 to be transported to the upper part inside the mixing box 3 by the auger 19 for re-stirring and mixing. When the mixing is completed, start the solenoid valve 22 to open, so that the mixed sludge and mushroom residue inside the mixing box 3 are transported into the discharge pipe 23 through the discharge pipe 21 and the solenoid valve 22, and then the mixed sludge and mushroom residue are discharged downward through the discharge pipe 23. At the same time, start the second motor 24 at the front end of the base 1 to drive the first transmission roller 25 to rotate. The first transmission roller 25 drives the third rotating rod 26 to rotate along the inside of the base 1. When the third rotating rod 26 rotates, it drives the conveyor belt 27 to rotate.

When the third rotating rod 26 rotates, it drives the first pulley 30 and the first transmission belt 31 to rotate simultaneously. The first transmission belt 31 rotates to drive the second pulley 32 to rotate. When the second pulley 32 rotates, it drives the outer side of the bidirectional reciprocating screw rod 34 to rotate along the inside of the fixed seat 33, and the front end of the bidirectional reciprocating screw rod 34 rotates along the inside of the second sleeve block 35. When the bidirectional reciprocating screw rod 34 rotates, it drives the moving blocks 36 at the front and rear ends on the outer side of the bidirectional reciprocating screw rod 34 to reciprocate along the outer side of the bidirectional reciprocating screw rod 34 at the same time. When the moving block 36 moves, it drives the cutting plate 37 to move simultaneously. When the cutting plates 37 at the front and rear ends move to the middle position, they will cut the mixed fuel discharged from the bottom end of the discharge pipe 23. At the same time, the moving block 36 will move along the outer side of the guide rod 38. The cut fuel falls onto the top of the conveyor belt 27, and then is transported to the right through the conveyor belt 27 and moves into the drying box 45. When the second gear 12 rotates, it drives the third pulley 39 to rotate. The third pulley 39 drives the second transmission belt 40 and the fourth pulley 41 to rotate simultaneously. The fourth pulley 41 drives the fifth rotating rod 42 to rotate. The fifth rotating rod 42 drives the third gear 43 and the fourth gear 44 to rotate simultaneously. When the third gear 43 and the fourth gear 44 rotate, they drive the sixth rotating rod 46 at the bottom end to rotate.Moreover, the sixth rotating rod 46 drives the rotating block 47 to rotate along the inside of the third sleeve block 48, and the sixth rotating rod 46 drives the fan 49 to rotate. At the same time, the drying box 45 is started, so that the fuel moved into the drying box 45 can be quickly dried. The drying is completed until the fuel moves out of the drying box 45, and then it continues to be conveyed to the right through the conveyor belt 27 until it falls into the feeding hopper 50, and then is conveyed to the combustion power generation device 2 through the conveying pipe 51. Then, the fuel is burned and generated electricity by the combustion power generation device 2.,
