Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement production equipment, in particular to a desulfurized gypsum feeding device. Background Art
[0002] Desulfurized gypsum is also called flue gas desulfurized gypsum, sulfur gypsum or FGD gypsum. Its main component is the same as natural gypsum, which is calcium sulfate dihydrate CaSO4·2H2O, with a content of ≥93%. Desulfurized gypsum is a by-product of the FGD process. The FGD process is a technology that uses lime-limestone to recover sulfur dioxide in flue gas from coal or oil combustion. The technology is to grind lime-limestone into slurry, and pass the flue gas containing SO2 after dust removal through a slurry scrubber to remove SO2. The lime slurry reacts with SO2 to generate calcium sulfate and calcium sulfite. Calcium sulfite is oxidized to calcium sulfate to obtain industrial by-product gypsum, called desulfurized gypsum, which is widely used in building materials and other industries. Desulfurized gypsum is added during cement production. When adding desulfurized gypsum, it is necessary to remove the larger particles inside the desulfurized gypsum to ensure the quality of cement. However, the traditional feeding device has no screening function, resulting in uneven coarseness of the added desulfurized gypsum, which in turn affects the quality of cement and cannot meet people's use.
[0003] In summary, the utility model solves the existing problems by designing a desulfurized gypsum feeding device. Utility Model Content

[0023] For examples, see Figure 1-4 , the utility model provides a technical solution:
[0024] A desulfurized gypsum unloading device comprises a box body 1, support pads 2 are installed at the four corners of the bottom of the box body 1, a discharge pipe 3 is installed at the bottom edge of the wider side of the outside of the box body 1, a drive motor 4 is installed on the wider side of the outside of the box body 1 and above the discharge pipe 3, grooves 101 are symmetrically opened on the tops of the two narrower side surfaces of the outside of the box body 1, a support rod 5 is installed at the bottom of the inner side of the groove 101, a return spring 6 is installed on the outer annular surface of the support rod 5, and a sliding block 7 is installed on the outer annular surface of the support rod 5 and above the return spring 6;
[0025] A screening frame 8 is installed inside the box 1 and between the two sliding blocks 7, a screen 9 is installed on the inner bottom of the screening frame 8, an inclined plate 10 is installed on the inner bottom of the box 1, and a rotating shaft 11 is installed between the two wider side surfaces inside the box 1 and below the screening frame 8, and bumps 12 are symmetrically installed on both ends of the outer ring surface of the rotating shaft 11.
[0026] Specifically, refer to Figure 1 and Figure 4 The outer ring surface of the support rod 5 is slidably connected to the inside of the sliding block 7, and the outer side surface of the sliding block 7 is slidably connected to the inner side wall of the groove 101, thereby ensuring that the stability of the cyclic vibration of the screening frame 8 is increased by sliding the sliding block 7 up and down on the outside of the support rod 5.
[0027] Furthermore, a discharge port is opened on the outer surface of the box body 1 and connected to the discharge pipe 3, and the inner bottom of the discharge port on the box body 1 is at the same height as the top edge of the lower end of the inner inclined plate 10 thereof, so as to facilitate the discharge of the screened desulfurized gypsum fine particles from the discharge pipe 3 after passing through the inclined plate 10.
[0028] Furthermore, the outer dimensions of the screening frame 8 match the inner wall dimensions of the box body 1, and the outer portion of the screening frame 8 is slidably connected to the inner wall of the box body 1, thereby ensuring that the screening frame 8 circulates up and down inside the box body 1 to generate vibrations to screen the desulfurized gypsum inside the screening frame 8.
[0029] For details, please refer to Figure 2 and Figure 3 One end of the rotating shaft 11 passes through the inner wall of the box body 1 and extends to the outside of the box body 1 and is connected to the output end of the driving motor 4, and the end of the rotating shaft 11 away from the driving motor 4 is rotatably connected to the other side wall inside the box body 1, thereby ensuring that the driving motor 4 drives the rotating shaft 11 to rotate and drives the two protrusions 12 to rotate. The two protrusions 12 rotate in a circular manner to squeeze the screening frame 8 to rise inside the box body 1 and stretch the reset spring 6 at the same time.
