Technical Field
[0001] The invention relates to the technical field of solid fuel mixing, in particular to a mixing and stirring device for preparing solid fuel. Background Art
[0002] Solid fuel is a large category of fuel, which is a solid combustible material that can generate heat or power. Most of them contain carbon or hydrocarbons. Natural ones include wood, peat, lignite, bituminous coal, anthracite, oil shale, etc., and processed ones include charcoal, coke, coal bricks, coal balls, etc. There are also some special varieties of solid fuel, such as solid alcohol and solid rocket fuel. Compared with liquid fuel or gas fuel, the combustion of solid fuel is generally more difficult to control, the efficiency is lower, and there is more ash powder. However, when the stirring rod in the prior art is used for stirring and mixing, the stirring position setting is relatively fixed, and only the solid fuel around the stirring rod can be stirred. The stirring range is small, and it can only be stirred at a fixed height, which makes the stirring efficiency low. Therefore, a mixing and stirring device for preparing solid fuel is invented to solve the above problems. Summary of the invention

When the sliding block moves downward, it drives the long rod connected to the front end to be pressed downward, so that the stirring blades connected to the bottom of the long rod can continuously stir the mixed materials.
[0005] Preferably, the lifting device includes a base, a support column is fixedly connected to the top of the base, a sliding plate is fixedly connected to one side of the outer surface of the support column, a movable plate is movably connected to the sliding plate and the outer surface of the support column, and a mixing tank is fixedly connected to the top of the movable plate.

[0008] Preferably, the hollow part inside the hollow block is movably connected with the first rotating column and the second rotating shaft, and the top of the first rotating column is fixedly connected to the bottom of the second rotating block, the outer surfaces of the first rotating column and the second rotating shaft are fixedly connected with gears, and the two gears are meshed with each other, the bottom of the second rotating shaft is fixedly connected with a movable column, and the bottom of the movable column is fixedly connected to the top of the stirring device.
[0009] Preferably, the stirring device includes a circular plate, and the top center of the circular plate is fixedly connected to the bottom of the movable column, and the outer side of the bottom of the circular plate is connected to several long columns and threaded rods, and the outer surfaces of several of the long columns and threaded rods are movably connected to several sliding blocks, and the front end centers of several of the sliding blocks are fixedly connected to fixed blocks.
[0010] Preferably, several of the fixed blocks are movably connected to the first push rod at the centers, several of the first push rods are movably connected to long rods at the grooves at both ends, several of the long rods are movably connected to the second push rods at the bottom ends, several of the second push rods are movably connected to a rotating shaft at the centers, and a stirring blade is movably connected to the outer surface of the bottom of the rotating shaft.
[0011] Compared with the prior art, the present invention provides a mixing and stirring device for preparing solid fuel, which has the following beneficial effects: 1. The mixing and stirring device for preparing solid fuel has a sliding plate arranged on the outer surface of a supporting column, and a movable plate movably connected to the sliding plate can be slid up and down. The stirring tank is fixedly connected to the movable plate, so the stirring tank can be driven to adjust its height together, and different heights can be adjusted for stirring, which can effectively improve the mixing efficiency of the stirring device. One end of the connecting block is connected to a motor, and the other end is connected to a movable device. The motor is used to generate electricity for rotation, thereby ensuring that the solid fuel is fully stirred during the mixing process, so that the mixing is more uniform.
[0012] 2.

When the first rotating block rotates, the second rotating block at the other end of the bandage can move with the first rotating block at the same time through the connection of the bandage, and the bottom of the second rotating block is fixedly connected to the top of the first rotating column. Therefore, after the first rotating column rotates, the gear on the outer surface will drive the rotation of another gear fixedly connected to the second rotating shaft, so that the stirring device at the bottom of the second rotating shaft will first stir in the center of the stirring tank, so that the stirring blades in the stirring device can better penetrate into the solid fuel, thereby realizing sufficient mixing and stirring of the fuel.

Several long columns and threaded rods are connected to the bottom of the circular plate, and sliding blocks are slidably connected to the outer surfaces of the long columns and the threaded rods. Therefore, when the threaded rod drives the sliding block to move up and down through the power generation rotation of the motor, the several long rods connected to the front end of the sliding block will also move up and down, so that the stirring blades connected to the bottom of the long rods can continuously stir the materials from top to bottom, ensuring that the mixed and stirred fuel burns more fully during the combustion process, reducing the generation of unburned substances and impurities, thereby reducing the emission concentration of pollutants.
[0014] 4. The mixing and stirring device for preparing solid fuel can move with the sliding block by setting the fixed block at the front end of the sliding block. When one of the sliding blocks moves downward under the rotation of the threaded rod, the long rods at both ends of several first push rods will push the inclination of the central movable connected shaft, so that the stirring blades connected to the bottom of the shaft can rotate to stir the fuel in the dead corner inside the stirring tank, ensuring that each fuel is evenly stirred and processed. In addition, the active stirring helps to reduce impurities and incombustibles in the solid fuel and improve the uniformity of the mixture. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the first rotating block 121 at the top of the motor 118, The first rotating block 121 can be driven to rotate by the power generation of the motor 118. When the first rotating block 121 rotates, the second rotating block 123 at the other end of the bandage 122 can move with the first rotating block 121 at the same time through the connection of the bandage 122.

By arranging the circular plate 21 and the movable column 128 together, the rotation of the movable column 128 can be used to drive the rotation of the stirring device 2 as a whole. The bottom of the circular plate 21 is connected with several long columns 22 and threaded rods 23, and the outer surfaces of the long columns 22 and threaded rods 23 are also slidably connected with sliding blocks 24. Therefore, when the threaded rods 23 drive the sliding blocks 24 to move up and down through the power generation rotation of the motor 118, the several long rods 27 connected to the front end of the sliding blocks 24 will also move up and down, so that the stirring blades 210 connected to the bottom of the long rods 27 can continuously stir the materials from top to bottom, ensuring that the mixed and stirred fuel burns more fully during the combustion process, reducing the generation of unburned materials and impurities, thereby reducing the emission concentration of pollutants. The front centers of the several sliding blocks 24 are all provided with fixed blocks 25, and the front centers of the several sliding blocks 24 are all fixedly connected to the rear ends of the fixed blocks 25.
[0024] A first push rod 26 is disposed at the center of each of the fixed blocks 25, and the centers of each of the fixed blocks 25 are movably connected to the center of the outer surface of the first push rod 26. Long rods 27 are disposed at the grooves at both ends of each of the first push rods 26, and the grooves at both ends of each of the first push rods 26 are movably connected to the top of the long rod 27. Second push rods 28 are disposed at the bottom ends of each of the long rods 27, and the bottom ends of each of the long rods 27 are movably connected to both ends of the second push rod 28.

The outer surface of the mixing tank 115 is provided with a stirring blade 210. By setting the fixed block 25 at the front end of the sliding block 24, it can move with the sliding block 24. When one of the sliding blocks 24 moves downward under the rotation of the threaded rod 23, the long rods 27 at both ends of the first push rods 26 will push the tilt of the central movable shaft 29, so that the stirring blade 210 connected to the bottom of the shaft 29 can rotate to stir the fuel in the dead corner inside the mixing tank 115, ensuring that each fuel is evenly stirred and processed. In addition, the active stirring helps to reduce impurities and incombustibles in the solid fuel and improve the uniformity of the mixture. The outer surface of the bottom of the shaft 29 is movably connected to the center of the stirring blade 210.
[0025] When in use, the fuel is first placed in the stirring tank 115 in the mixing device 1, and then stirred by the stirring device 2. The mixing device 1 includes a lifting device 11 and a movable device 12. The support column 112 in the lifting device 11 is provided with a sliding plate 113 on the outside, and a movable plate 114 is connected to the outer surface of the sliding plate 113, so the movable plate 114 will slide on the outer surface of the sliding plate 113 to adjust the height of the stirring tank 115 fixedly connected to the top of the movable plate 114. In this way, the height of the stirring is adjusted to better control the shear force during the stirring process, which is particularly important for some solid fuels that require a specific degree of mixing. The motor 118 fixedly connected to one end of the connecting block 116 will generate electricity to drive the movable device 12 and the stirring device 2 connected to the other end to rotate. The first rotating block 121 in the movable device 12 is connected to the motor 118 at the bottom, so it will rotate through the power generation of the motor 118. When the first rotating block 121 rotates, the bandage 122 connected to the outer surface will drive the second rotating block 123 at the other end to rotate together with the first rotating block 121, so that the first rotating column 125 and the gear 127 fixedly connected to the bottom of the second rotating block 123 can move. The outer surface of the second rotating shaft 126 is also connected to the same gear 127, and the two gears 127 are meshed and connected. Therefore, the second rotating shaft 126 can also rotate and stir the stirring device 2 connected to the bottom at the center of the stirring tank 115 driven by the first rotating column 125. This mixing method not only improves the mixing efficiency of the mixer, but also makes it difficult for the solid fuel to clump and stratify during the mixing process, thereby achieving highly uniform mixing of the materials and further improving the uniformity of the mixture. The stirring device 2 includes a circular plate 21, the top center of which is connected to a movable column 128, and the stirring device 2 is driven to rotate and stir as the movable column 128 rotates. Several long columns 22 and threaded rods 23 are connected to the outer side of the bottom of the circular plate 21, and the threaded rods 23 are moved by the power generation of the motor 118, so that the sliding blocks 24 on the outer surfaces of the threaded rods 23 can move up and down, and a first push rod 26 is provided at the front end of each sliding block 24, and long rods 27 are movably connected at both ends of the first push rod 26. Therefore, when the sliding block 24 moves from top to bottom, the long rod 27 will push the rotating shaft 29 connected in the middle of the long rods 27 downward, so that the stirring blade 210 connected to the bottom of the rotating shaft 29 can stir the fuel from top to bottom. When one of the threaded rods 23 rotates, the first push rod 26 will drive the stirring blade 210 to deviate in direction, and stir the fuel located in the dead corner of the stirring tank 115, which is of great significance for improving the stability and safety of the combustion process.
