The unsealed drying cylinder 1 facilitates the user to replace the scraper 52. The feed port 3 is used to convey desulfurized gypsum into the drying cylinder 1 and discharge the dried desulfurized gypsum from the drying cylinder 1. The top of the channel connecting the feed port 3 and the inside of the drying cylinder 1 overlaps with the top of the end face of the drying cylinder 1, ensuring that the feed port 3 can discharge all the desulfurized gypsum in the drying cylinder 1. The sealing cover 32 can seal the feed port 3 to prevent the desulfurized gypsum in the drying cylinder 1 from leaking during the use of the device. After the sealing cover 32 is installed on the feed port 3, the sealing plate of the sealing cover 32 sealing the feed port 3 is in the same plane as the inner wall of the drying cylinder 1, ensuring that the desulfurized gypsum will not enter the inside of the feed port 3 during the stirring process, ensuring the working effect of the electric stirring shaft 5 and the drying cylinder 1. When the device discharges the dried desulfurized gypsum, the telescopic cylinder 24 is controlled to extend. The extended telescopic cylinder 24 will lift one end of the base 2. The lifted base 2 rotates around the hinge shaft of the base 2. As the base 2 rotates, the end of the drying cylinder 1 with the feed port 3 tilts downward, facilitating the device to discharge the dried desulfurized gypsum from the drying cylinder 1.

[0022] Specifically, a protrusion with a T-shaped cross section is provided on the side wall of the installation frame 51 , and a groove matching with the protrusion on the side wall of the installation frame 51 is provided on the scraper 52 .

[0023] The cooperation between the side wall protrusions of the mounting frame 51 and the side wall grooves of the scraper 52 plays a guiding role. When the user installs the scraper 52 on the mounting frame 51, the scraper 52 slides on the side wall protrusions of the mounting frame 51 through the cooperation between the side wall grooves and the side wall protrusions of the mounting frame 51, thereby realizing the installation of the scraper 52. The installation method of the scraper 52 ensures the stability of the scraper 52 when the user installs it on the mounting frame 51, and is convenient for the user to install and disassemble the scraper 52. The cooperation between the side wall grooves of the scraper 52 and the side wall protrusions of the mounting frame 51 plays a limiting role, avoiding the scraper 52 from shaking during rotation, thereby ensuring the working effect of the scraper 52.

[0024] Specifically, a groove is provided on the inner wall of the feed port 3, a feed sleeve 31 is installed on the groove of the inner wall of the feed port 3 by screws, and a sealing cover 32 is installed on the feed sleeve 31 by screws.

[0025] The inner wall groove of the feed port 3 is used to install the feed sleeve 31. The feed sleeve 31 can reduce the wear of the feed port 3 during the user's installation and removal of the sealing cover 32, thereby extending the service life of the feed port 3. The installation method of the feed sleeve 31 is convenient for the user to replace the feed sleeve 31.

[0026] Specifically, an annular protrusion is provided on the outer wall of the opening of the feed port 3 , and a groove matching with the annular protrusion of the feed port 3 is provided on the side wall of the feed sleeve 31 .

[0027] The screws set on the feed sleeve 31 pass through the side wall protrusion of the feed port 3. The position of the groove where the feed sleeve 31 cooperates with the side wall protrusion of the feed port 3 is set toward the side wall protrusion of the feed port 3. The side wall groove of the feed sleeve 31 and the screws for fixing the feed sleeve 31 are located away from the opening of the feed sleeve 31, ensuring that the desulfurized gypsum will not fall onto the screws when the user feeds the desulfurized gypsum into the interior of the feed sleeve 31, making it easy for the user to disassemble the feed sleeve 31.

[0028] Specifically, a slider 25 is slidably mounted on the bottom surface of the other end of the support plate 21 , and the slider 25 is hinged on the telescopic end of the telescopic cylinder 24 .

[0029] The telescopic cylinder 24 is hinged to the slider 25. The slider 25 is slidably mounted on the bottom surface of the base 2.

The slider 25 hinged to the telescopic cylinder 24 ensures that the movement of the slider 25 is not hindered, ensuring that the telescopic cylinder 24 can smoothly push the base 2 and guaranteeing the working effect of the telescopic cylinder 24. The groove for installing the slider 25 does not penetrate the side wall of the base 2, ensuring that the slider 25 does not break away from the base 2 during the movement. There are protrusions on the side wall of the slider 25, and there are grooves on the side wall of the groove for installing the slider 25 that cooperate with the protrusions on the side wall of the slider 25. The cooperation between the protrusions on the side wall of the slider 25 and the matching grooves ensures that the slider 25 does not break away from the base 2, guaranteeing the stability of the base 2.

[0030] Specifically, several guide rollers 23 are provided on the top surface of the convex part of the top surface of the support plate 21.

[0031] During the rotation of the drying cylinder 1, the guide rollers 23 will be driven to rotate by the rotating drying cylinder 1. The rotating guide rollers 23 reduce the friction suffered by the drying cylinder 1 during the rotation process, thereby reducing the damage suffered by the drying cylinder 1 during the rotation process and extending the service life of the drying cylinder 1.

[0032] Specifically, there are grooves on the side wall of the moving groove 22, and there are protrusions on the side wall of the top convex part of the support plate 21 that cooperate with the grooves on the side wall of the moving groove 22.

[0033] The cooperation between the groove on the side wall of the moving groove 22 and the top convex part of the support plate 21 plays a role in limiting, guaranteeing the stability of the drying cylinder 1 during the rotation process and the base 2 when it is jacked up. The position where the side wall protrusion of the top convex part of the support plate 21 is set is at the top of the side wall of the top convex part of the support plate 21. The position where the side wall protrusion of the top convex part of the support plate 21 is set increases the contact area between the top convex part of the support plate 21 and the drying cylinder 1, reduces the pressure on the guide rollers 23, and extends the service life of the guide rollers 23.
