[0024] See also Figure 1-5 The utility model discloses a weighing and feeding device for a phosphogypsum modifier, comprising an electronic scale 1 and a weighing box 2 installed at one end of the electronic scale 1, a discharge port 21 is arranged on one side of the weighing box 2, a sealing plate 3 for sealing the weighing box 2 is installed in the discharge port 21, the sealing plate 3 is unfolded and adjusted by rotation, a positioning component which is rotatably connected and fixed to the weighing box 2 is installed in the sealing plate 3, a guide component for guiding the modifier to the surface of the unfolded sealing plate 3 is arranged in the weighing box 2, and a protective layer 8 for cooperating with the weighing box 2 to unfold in a fan shape is arranged between the sealing plate 3 and the weighing box 2.

[0025] See also Figure 3The discharge port 21 is provided on one side of the surface of the weighing box 2, the width of the discharge port 21 is greater than the spacing inside the weighing box 2, and the end of the inner wall of the weighing box 2 close to the electronic scale 1 is inclined toward the discharge port 21. Under the inclined guidance of the inclined surface of the bottom end of the weighing box 2, the weighed improver can be automatically discharged from the weighing box 2 through the discharge port 21. An active groove 22 facing the center of the weighing box 2 is provided at an angle of the inner wall of the discharge port 21 close to one end of the electronic scale 1. The active groove 22 is used to accommodate the guide block 6 and the spring sheet 7 in the unfolded state, and does not affect the installation of the sealing plate 3, so that the sealing plate 3 can fit the discharge port 21 to seal the weighing box 2. The inner wall of the discharge port 21 is close to one side of the weighing box 2 and is provided with a receiving groove 23 at two angles far away from each other. The receiving groove 23 is used to accommodate the protective layer 8 in the unfolded state, and positioning holes 24 are provided on both sides of the inner wall of the discharge port 21 and at one end away from the electronic scale 1.

[0026] See also Figure 1 The end of the sealing plate 3 close to the electronic scale 1 is rotatably connected between the two sides of the inner wall of the discharge port 21, and the protective layer 8 is installed between the sealing plate 3 and one side of the inner wall of the storage groove 23. The protective layer 8 can be opened in a fan shape as the sealing plate 3 rotates and expands. The protective layer 8 and the sealing plate 3 form an inclined opening extending outward, which can guide the improver discharged along the discharge port 21 to other containers for automatic loading. The fan-shaped protective layer 8 closes the angle between the sealing plate 3 and the discharge port 21, which can prevent the improver from leaking from the side during the discharge process. A slot 31 is provided on the side of the sealing plate 3 away from the weighing box 2, and a first threaded hole 32 and a second threaded hole 33 are respectively provided in the center of the inner wall of the slot 31 away from each other on both sides. The thread directions of the first threaded hole 32 and the second threaded hole 33 are opposite, and the center of the circle coincides with the center of the positioning hole 24.

[0027] See also Figure 4 The positioning assembly is composed of a threaded sleeve 4 and an adjusting rod 5. The threaded sleeve 4 is respectively installed in the first threaded hole 32 and the second threaded hole 33. The ends of the two threaded sleeves 4 that are away from each other are sealed and installed in the positioning hole 24. The two ends of the adjusting rod 5 are rectangular and inserted into the inner sides of the two threaded sleeves 4. The adjusting rod 5 is inserted into the inner sides of the two threaded sleeves 4 and cannot rotate. The adjusting rod 5 can be rotated to control the two threaded sleeves 4 to rotate at the same time. Affected by the different thread directions of the first threaded hole 32 and the second threaded hole 33, when the two threaded sleeves 4 rotate in the same direction and are threadedly connected with the first threaded hole 32 and the second threaded hole 33, they will separate or approach at the surface level of the adjusting rod 5. The staff can control the separation movement of the two threaded sleeves 4 to form an insertion with the positioning hole 24 in the discharge port 21 to fix the sealing plate 3, or control the two threaded sleeves 4 to move close to separate them from the positioning hole 24, cancel the fixed relationship of the sealing plate 3, and control the sealing plate 3 to be deployed for use.

[0028] See also Figure 2 The guide assembly is composed of a guide block 6 and a spring sheet 7. The guide block 6 is installed between the two ends of the inner wall of the movable groove 22. The guide block 6 is triangular in shape. One end of the guide block 6 is in contact with the surface of the sealing plate 3, and the other two ends are respectively facing the center of the electronic scale 1 and the weighing box 2. The spring sheet 7 is installed between the guide block 6 and the side of the inner wall of the movable groove 22 away from the sealing plate 3. When the sealing plate 3 is installed in the discharge port 21 to seal the weighing box 2, the sealing plate 3 will push the guide block 6 to compress the spring sheet 7 and store them together in the movable groove 22. When the sealing plate 3 is unfolded, the spring sheet 7 loses the external force, pushing the guide block 6 to be fixed between the sealing plate 3 and the discharge port 21 in an inclined state, so that the improver discharged from the discharge port 21 is smoothly guided to the surface of the sealing plate 3 and discharged into the phosphogypsum preparation container for automatic feeding processing. The guide block 6 fills the gap between the discharge port 21 and the sealing plate 3 after it is unfolded, thereby preventing the improver from leaking during the feeding process.

[0029] When it is necessary to feed the weighed modifier, firstly, the discharge port 21 is directed toward the container port for preparing phosphogypsum, and the adjusting rod 5 is rotated to make the threaded sleeves 4 at both ends rotate in the first threaded hole 32 and the second threaded hole 33 respectively. Affected by the opposite thread directions of the first threaded hole 32 and the second threaded hole 33, after the two threaded sleeves 4 rotate, they move along the outside of the adjusting rod 5 in the first threaded hole 32 and the second threaded hole 33 and approach each other. During the movement, the two threaded sleeves 4 are disengaged from the positioning hole 24, the sealing plate 3 is unfixed, and the sealing plate 3 is rotated to open. The protective layer 8 opens in a fan shape as the sealing plate 3 rotates. At the same time, when the sealing plate 3 rotates to open, the spring sheet 7 loses the outer pressure, resets and rebounds, and pushes the guide block 6 to move, so that the guide block 6 is fixed between the sealing plate 3 and the discharge port 21 in an inclined state. The modifier in the weighing box 2 is discharged along the discharge port 21 under the action of the inclined surface end, and is discharged into the phosphogypsum preparation container through the guide block 6 and the surface of the sealing plate 3 for automatic feeding.
