The inner pressing ring 332 and the outer pressing ring 331 are arc-shaped rings, the arc-shaped length of the inner pressing ring 332 is the path length of the rotating ring 320 from the initial state feeding to the sprinkling mechanism for completing sprinkling, and the arc-shaped length of the outer pressing ring 331 is the path length of the rotating ring 320 from the sprinkling mechanism to the discharge hole 220.
The state that the hopper 340 is positioned at one end below the feed inlet 230 is called an initial state, the motor 410 is started, the motor 410 rotates to drive the telescopic frames to drive the rotating shaft 311 to rotate, the rotating shaft 311 rotates to drive the inner ring 318, the outer ring 317, the inner pressing ring 332, the outer pressing ring 331 and the rotating ring 320 to synchronously rotate, the rotating ring 320 rotates to drive the hopper 340 to rotate, the slag cavity 270 senses blanking when the hopper 340 rotates, the hopper 340 is filled with the slag cavity 270 and the hopper 340 is scraped in the rotating process, the weight of the hopper 340 is gradually increased along with the rotation of the hopper 340, the rotating ring 320 moves downwards relative to the rotating shaft 311, the pressing block 322 is arranged on the rotating ring 320, the thickness of the pressing block 322 is larger than that of the rotating ring 320, the upper surface of the pressing block 322 is in the same horizontal plane with the upper surface of the rotating ring 320, and the central line of the radial direction of the pressing block 322 coincides with the central line of the radial direction of the hopper 340.
Therefore, because the volume of the hopper 340 is fixed, the heavier the hopper 340 is, the smaller the slag particles are, the heavier the slag weight in the hopper 340 is, the pressure of the hopper 340 to the swivel 320 makes the pressing block 322 press the inner pressing ring 332 and then press the inner ring 318, the inner ring 318 moves downwards, the expansion bracket stretches outwards, the diameter of the part connected with the conveying belt 430 is enlarged, the distance from the initial state feeding to the sprinkling mechanism where the swivel 320 finishes sprinkling is called the first travel, when the speed of the motor 410 is fixed, the time of the swivel 320 in the first travel is then prolonged, and the rotation time of the swivel 320 from the blanking to the sprinkling stage is in direct proportion to the slag mass, namely the larger the slag mass in the hopper 340 is, the larger the downward movement amount of the swivel 320 presses the inner ring 318 is, the expansion bracket moves outwards, the larger the diameter is, the longer the sprinkling time is, the sprinkling time is the longer, the water adding amount is adapted to the slag weight is adapted, the full energy is ensured, and the unnecessary water is completely discharged and the redundant water is recovered.
Swivel 320 rotates and leaves the watering mechanism, stops watering for slag and water reaction in hopper 340 produce steam, makes briquetting 322 leave the back of inner ring 318, and briquetting 322 and outer clamping ring 331 contact, and briquetting 322 lower extreme sets up to the arc, and outer clamping ring 331 sets up to the arc with the adjacent one end of interior clamping ring, makes briquetting 322 can overcome the displacement difference that outer clamping ring 331 produced for interior clamping ring 332 when interior clamping ring 332 pushes down, and here can make interior clamping ring 332's the volume of shifting down assurance can make briquetting 322 follow interior clamping ring 332 and remove on the outer clamping ring 331 through adjusting the distance between first installation piece and head rod 316 and the second connecting rod 319.
Because the heavier the hopper 340, the larger the surface area of the slag particles, the faster the reaction, so the briquetting 322 presses down the outer press ring 331, the briquetting 322 presses down the outer press ring 331 and then presses down the outer ring 317, the outer ring 317 moves down, so that the expansion bracket compresses inwards, the part connected with the conveying belt 430 becomes smaller in diameter, the path from the position of the sprinkling mechanism to the position of the discharge hole 220 is called a second path, when the speed of the motor 410 is constant, the time of the rotary ring 320 in the second path becomes shorter, the rotation time of the rotary ring 320 from the sprinkling stage to the reaction stage is inversely proportional to the reaction speed of the slag and water, namely, the larger the mass of the slag in the hopper 340, the smaller the surface area, the quicker the reaction, the larger the downward movement of the rotary ring 320, the more the diameter of the expansion bracket moves inwards, the faster the time of the rotary ring 320 is driven by the motor 410, the time of the rotary ring 320 becomes shorter, the reaction time is adapted to the weight of the slag, and the energy is ensured to be completely and the uninterrupted vapor recovery is generated.
When the swivel 320 rotates until the pressing wall 341 on the hopper 340 contacts the projection 260, the hopper 340 is turned over to pour the reacted slag to the discharge hole 220. The reaction is ended. The housing is provided with a slot 110 for mounting a motor 410, the motor 410 being slidably mounted to the housing. A second elastic member is provided between the motor 410 and the inner wall of the housing to keep the conveyor belt 430 in a tight state all the time when the expansion bracket is moved outward and inward.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
