Description

Technical Field

[0001] The present application relates to the technical field of alternative fuel production, and more specifically, to an integrated pre-processing device for unpacking and shredding for the production of alternative fuels. Background Art

[0002] Alternative fuel, also known as solid alternative fuel or recycled fuel, is a combustible fuel produced from solid waste after processing. This fuel can be used as an energy source to replace traditional fossil fuels (such as coal, crude oil and natural gas). The production of alternative fuels aims to reduce dependence on limited natural resources while achieving effective recycling and resource utilization of waste. The preparation process usually includes first collecting waste and collecting various types of solid waste from sources such as domestic waste, construction waste, and industrial waste. Sorting and classification: The collected waste is sorted and classified to distinguish useful combustible parts from other non-combustible parts (such as metal, glass, stone, etc.). Processing and treatment: The combustible part of the waste is crushed, broken and dried to make it a solid fuel suitable for combustion. Storage and packaging: The processed alternative fuel is stored and packaged for transportation and sale.

[0003] After the alternative fuel is packaged, it cannot be directly put into the furnace due to its large size. Therefore, the alternative fuel needs to be shredded and screened for incineration. However, the shredded alternative fuels are of different sizes, which leads to the calorific value of the alternative fuel entering the furnace for incineration not being at a uniform level. Therefore, the alternative fuel needs to be screened through a screen. However, the screen is prone to clogging after long-term use, affecting the screening effect.

A discharge port 19 is provided at the bottom of one end of the unpacking and shredding machine 1 to discharge the screened alternative fuel particles from the discharge port 19.

[0050] The working process of the present application is as follows: the first screen 701 is inserted into the fixing groove 601 through the fixing frame 605. At this time, the surface of the fixing frame 605 will squeeze the second spring 603 and the latch 604. When the fixing frame 605 is in the right position, the second spring 603 is reset, pushing the latch 604 to be inserted into the latch groove 606, so that the fixing frame 605 is stuck on the fixing sleeve 504, and the first bolt 609 is screwed. The first bolt 609 passes through the first bolt hole 608 and is threadedly connected to the fixing sleeve 504, so that the first screen 701 can be fixed to the fixing sleeve 504 through the fixing frame 605, so that the first screen 701 can be located below the shredding cutter 206 with a certain gap. Then, the positioning block 802 is inserted into the positioning groove 801, and the second bolt 804 is screwed. The second bolt 804 passes through the second bolt hole 803 and is threadedly connected to the unpacking and shredding machine 1, so that the positioning block 802 can be fixed to the unpacking and shredding machine 1, so that the subsequent machine can be properly operated. In common use, according to the particle size of the alternative fuel required, the second push rod 709 is activated to drive the second screen 706 to move on the first screen 701. By adjusting the position of the second screen 706, the aperture between the first screen hole 703 and the second screen hole 707 is changed so that suitable alternative fuel particles can be discharged from the screen hole. The alternative fuel package 12 is placed on the chain plate roller chain 9, and the chain plate reduction motor 18 is activated to drive the chain plate roller chain 9 to rotate. Under the action of the hook chain 10, the alternative fuel package 12 is dragged forward and moved to the position of the cutting mechanism 13. The second drive motor 1301 is activated to rotate the multiple sets of fixed rods 1302 through the transmission sprocket 1304. The fixed rods 1302 drive the cutting wheel 1303 to rotate, cutting the packaging belt, allowing the alternative fuel to scatter, and some of it will fall into the groove 17. The first push rod 15 is then activated.The push head 16 is automatically controlled by the program to realize slow pushing and fast withdrawing, and the push head 16 is used to push the alternative fuel forward so as to push the scattered alternative fuel into the shredding cutter 206 and the screen for shredding and screening, thereby improving the crushing effect. Then, the first driving motor 201 is started to drive the first transmission wheel 202 to rotate. When the first transmission wheel 202 rotates, the second transmission wheel 204 can be driven to rotate through the transmission belt 203, so that the second transmission wheel 204 can drive the shredding cutter 206 to rotate through the connecting rod 205, so that the alternative fuel is shredded. At the same time, when the connecting rod 205 rotates, it can drive the first pulley 301 to rotate. When the first pulley 301 rotates, the second pulley 303 can be driven to rotate through the belt 302, so that the second pulley 303 can drive the first protrusion 307 to rotate through the first rotating rod 304, and the first rotating rod 304 can drive the second rotating rod 306 to rotate through the reciprocating screw rod 401, so that the two groups of first protrusions 307 can rotate at the same time. When the first protrusion 307 rotates, the protrusion at the top pushes the second protrusion 702 to make the first screen 701 move upward, and the first screen 701 moves upward in the limiting groove 501 through the fixing frame 605, the fixing sleeve 504 and the fixing sleeve 504. At the same time, the fixing sleeve 5 One end of the first spring 506 is pressed by the first spring 506. When the protrusion at the top of the first protrusion 307 passes the second protrusion 702, the pressed first spring 506 is reset, so that the fixing sleeve 504 drives the fixing frame 605 and the first screen 701 to move up and down, so that the first screen 701 can vibrate, and when the first screen 701 drives the second screen 706 to move up, a certain extrusion angle is formed between the shredding cutter 206 and the tooth block 708, so as to improve the shredding effect of the alternative fuel. This is repeated, and the shredded alternative fuel is discharged through the holes between the first screen hole 703 and the second screen hole 707, so that the alternative fuel with uniform particle size can be discharged. This ensures that the calorific value of the alternative fuel entering the furnace remains uniform, making subsequent alternative fuel combustion more economical. At the same time, when the first rotating rod 304 drives the reciprocating screw 401 to rotate, it can also drive the fixed plate 403 to move left and right. The movement of the fixed plate 403 drives the brush 404 to clean the bottom of the first screen 701. The brush 404 can be inserted into the mesh holes according to the up and down movement of the first screen 701 to remove any alternative fuel that is clogged in the mesh holes, preventing the blockage from affecting the subsequent discharge of alternative fuel particles. This is the operating principle of this integrated unpacking and shredding pre-processing device for preparing alternative fuels.
