[0020] like Figure 1-3 As shown, a material extractor in a fluidized bed working state comprises a barrel body 1, a lower barrel cover 13 is detachably connected to the bottom end of the barrel body 1, a traction rope 10 is arranged on the upper side of the outer side of the barrel body 1, and a partition plate 14 is arranged on the left side of the inner side of the barrel body 1 to separate the barrel body 1 into a guide chamber 8 on the left side and a material extracting chamber 9 on the right side;
[0021] Four fixed shafts 4 are arranged on the inner wall at the bottom of the material taking chamber 9, a first limiting column 6 is arranged inside the barrel body 1 above each fixed shaft 4, a flip plate 5 is sleeved outside each fixed shaft 4, the flip plate 5 is rotatably connected to the fixed shaft 4, the part of the flip plate 5 located on the left side of the fixed shaft 4 is the first flip plate 5-1, the part of the flip plate 5 located on the right side of the fixed shaft 4 is the second flip plate 5-2, and the length of the first flip plate 5-1 is greater than the length of the second flip plate 5-2; a second limiting column 7 is arranged at the lower end of the left side wall inside the material taking chamber 9;
[0022] A first rotating shaft 15-1 is provided at the upper end of the left side wall of the guide chamber 8, and a second rotating shaft 15-2 is provided at the lower end of the right side wall. The position changing rope 3 passes around the first rotating shaft 15-1 and the second rotating shaft 15-2 and extends into the material taking chamber 9 through the pipe through hole 11 on the partition plate 14. The position changing rope 3 is provided with a flipping rope 2 at a corresponding position below each second flipping plate 5-2. One end of the flipping rope 2 is fixedly connected to the position changing rope 3, and the other end passes through the hole inside the second flipping plate 5-2 from bottom to top and is fixedly connected to the upper end of the second flipping plate 5-2.
[0023] A third limiting column 12 is provided at the lower end of the right side wall inside the material taking chamber 9. When the flip plate 5 closes the bottom of the material taking chamber 9, the second flip plate 5-2 of the rightmost flip plate 5 is located below the third limiting column 12 and abuts against the third limiting column 12; the first flip plate 5-1 of the leftmost flip plate 5 is located above the second limiting column 7 and abuts against the second limiting column 7, and the first flip plate 5-1 of the right flip plate 5 is located above the second flip plate 5-2 of the left flip plate 5.
[0024] The working process of the utility model is as follows:
[0025] Material placement and material collection process: After the sorting experiment is completed, the lower barrel cover 13 is removed, and the material collector of the fluidized bed in the working state of the utility model is placed at the position of the fluidized bed to be collected by the traction rope 10, and then the displacement rope 3 is pulled horizontally to the left on the left side of the first rotating shaft 15-1, so that the flip rope 2 drives the second flip plate 5-2 to rotate clockwise until the first flip plate 5-1 abuts against the first limit column 6 (such as Figure 3 A position), start to take the material, the flowing material enters the taking chamber 9 from the bottom;
[0026] Lifting process: After the material is taken, when the material container is lifted upward by the traction rope 10, the horizontal leftward pulling force applied to the displacement rope 3 is stopped. Since the gravity of the first flip plate 5-1 is greater than the gravity of the second flip plate 5-2, and the mass of the material above the first flip plate 5-1 is greater than the mass of the material above the second flip plate 5-2, the flip plate 5 rotates counterclockwise until the first flip plate 5-1 of the leftmost flip plate 5 is located above the second limit column 7 and abuts against the second limit column 7 (such as Figure 3B position), the flip plate 5 completes the closure of the material taking chamber 9;
[0027] Discharging process: After the material collector is taken out of the fluidized bed by the traction rope 10, the displacement rope 3 is pulled horizontally to the left on the left side of the first rotating shaft 15-1, so that the flip rope 2 drives the second flip plate 5-2 to rotate clockwise until the first flip plate 5-1 abuts against the first limiting column 6 (such as Figure 3 A position), the material starts to be discharged, and the flowing material slides from the material taking chamber 9 to the bottom due to gravity;
[0028] Recovery process: After all the materials in the material extractor are taken out, stop applying the horizontal leftward pulling force to the displacement rope 3. Since the gravity of the first flip plate 5-1 is greater than the gravity of the second flip plate 5-2, and the mass of the material above the first flip plate 5-1 is greater than the mass of the material above the second flip plate 5-2, the flip plates 5 rotate counterclockwise until the first flip plate 5-1 of the leftmost flip plate 5 is located above the second limit post 7 and abuts against the second limit post 7 (such as Figure 3 B position), the flip plate 5 completes the closing of the material taking chamber 9, and the material taker can proceed to the next material placement and taking process.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
