[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a calcium fluoride sludge drying device, including a base plate 1, an outer shell 2, a rotating drum 3, and an air conveying hopper 4. The outer shell 2 is fixedly installed on the top of the base plate 1. The rotating drum 3 is rotatably connected inside the outer shell 2. The air conveying hopper 4 is located at the left end of the rotating drum 3. A gas heating mechanism is located on the left side of the air conveying hopper 4. A rotating mechanism is located on the left side of the base plate 1. A feed pipe 5 is connected to the right end of the top of the outer shell 2. A discharge pipe 6 is connected to the left side of the bottom of the outer shell 2. A dispersing mechanism is located inside the rotating drum 3. The bottom end of the feed pipe 5 has an inclined end extending to the right end of the inside of the rotating drum 3. The feed pipe 5 can transport the calcium fluoride sludge into the right end of the rotating drum 3, and then drive the rotating drum 3 to rotate through the rotating mechanism, so as to move the calcium fluoride sludge from right to left. The dispersing mechanism inside the rotating drum 3 can automatically disperse the calcium fluoride sludge. The gas heating mechanism delivers heated air into the interior of the rotating drum 3 to heat and dry the calcium fluoride sludge. The moisture and dust generated during the drying process are transported to the dust removal equipment through the exhaust pipe 7 for treatment to avoid pollution to the environment and equipment. The dust removal equipment usually adopts high-efficiency dust removal technologies such as bag dust collectors or cyclone dust collectors. The dried calcium fluoride sludge is discharged out through the discharge pipe 6.

[0020] The rotating mechanism includes a first gear 11, a second gear 12, and a self-locking motor 13. The first gear 11 is fixedly connected to the left end of the air conveying hopper 4, and the second gear 12 is rotatably connected to the left side of the base plate 1. The outer walls of the first gear 11 and the second gear 12 mesh with each other. The self-locking motor 13 is fixedly installed on the left side of the base plate 1. The output end of the self-locking motor 13 is fixedly connected to the left end of the second gear 12. The output end of the self-locking motor 13 can drive the second gear 12 to rotate. The second gear 12 meshes with the first gear 11, and the first gear 11 is connected to the air conveying hopper 4 as a whole. The air conveying hopper 4 is also connected to the rotating drum 3, so that the self-locking motor 13 can drive the air conveying hopper 4 and the rotating drum 3 to rotate.

[0021] The dispersing mechanism includes a spiral blade 8, a rotating frame 9, and a guide plate 10. The spiral blade 8 is fixedly connected to the right end of the inside of the rotating drum 3. Multiple rotating frames 9 are hinged to the middle of the inside of the rotating drum 3. The guide plate 10 is fixedly connected to the left end of the inside of the rotating drum 3. The spiral blade 8 has a thread direction from right to left. The rotating frames 9 have rounded corners on both sides. The outer side of the guide plate 10 has a triangular support block connected to the rotating drum 3. The spiral blade 8 rotates with the rotating drum 3. The spiral blade 8 can drive the calcium fluoride sludge to move from right to left, so that the calcium fluoride sludge moves to the area of ​​the rotating frame 9. The rotating drum 3 can drive the rotating frame 9 to swing. The swinging rotating frame 9 can disperse the calcium fluoride sludge and move the calcium fluoride sludge directly to the area of ​​the guide plate 10. The rotating drum 3 turns the calcium fluoride sludge with the guide plate 10 until it is completely dried, so that the calcium fluoride sludge is continuously turned inside the rotating drum 3, improving the drying effect of the calcium fluoride sludge.

[0022] The bottom plate 1 is provided with a material support platform 19 at the top. The discharge pipe 6 is parallel to the material support platform 19 in the vertical direction. A connecting plate 20 is symmetrically fixed to the left end of the rotating drum 3. The left end of the connecting plate 20 is fixedly connected to the right end of the air conveying hopper 4. When the calcium fluoride sludge moves to the left end of the rotating drum 3, it falls into the discharge pipe 6 through the gap between the air conveying hopper 4 and the rotating drum 3, and then falls onto the material support platform 19 through the discharge pipe 6, and slides down to the outside through the material support platform 19 for discharge.

[0023] The gas heating mechanism includes a fan 14, a gas supply pipe 15, and a gas heating chamber 16. The gas heating chamber 16 is located on the left side of the base plate 1. The gas heating chamber 16 is symmetrically connected to both sides of the gas supply pipe 15. The right side of the gas heating chamber 16 is connected to the left end of the gas supply hopper 4 through the gas supply pipe 15. The fan 14 is located on the left side of the base plate 1. The left side of the gas heating chamber 16 is connected to the output end of the fan 14 through the gas supply pipe 15.

[0024] The input end of the fan 14 is connected to a filter element, the outside of the gas heating chamber 16 is connected to a gas pipe, the inside of the gas heating chamber 16 is equipped with a stove, the inside of the gas delivery hopper 4 is equipped with a filter screen 17, and one side of the filter screen 17 is fixedly connected to multiple air distribution pipes 18.

[0025] The blower 14 delivers air into the gas heating chamber 16 through the gas pipe 15. The filter element filters the air once. The gas enters the stove through the gas pipe, passes through the valve hole, gas valve core, and injector tube, and finally reaches the nozzle. The gas ejected from the nozzle mixes with the primary air drawn in from the air damper in the injector to form a mixture. The mixture flows out through the burner hole and ignites after encountering the ignition source generated by the igniter. After ignition, the gas receives secondary air replenishment from around the burner to complete combustion. During this process, the flame is ejected upward through the flame jet area and remains stable to heat the air entering the gas heating chamber 16. The heated air is then delivered into the gas hopper 4. The hot air is divided into multiple streams and delivered into the rotating drum 3 through the air distribution pipe 18. The filter screen 17 filters the hot air again. The hot air enters the rotating drum 3 to heat the calcium fluoride sludge and remove the moisture inside the calcium fluoride sludge.

[0026] In this calcium fluoride sludge drying device, the output end of the self-locking motor 13 can drive the second gear 12 to rotate. The second gear 12 meshes with the first gear 11, and the first gear 11 is connected to the air conveying hopper 4 as a whole. The air conveying hopper 4 is also connected to the rotating drum 3, so that the self-locking motor 13 can drive the air conveying hopper 4 and the rotating drum 3 to rotate. The spiral blades 8 rotate together with the rotating drum 3, and the spiral blades 8 can drive the calcium fluoride sludge to move from right to left, so that the calcium fluoride sludge moves to the area of ​​the rotating frame 9. The rotating drum 3 can drive the rotating frame 9 to swing. The swinging rotating frame 9 can break up the calcium fluoride sludge and move it directly to the area of ​​the guide plate 10. The rotating drum 3 tumbles the calcium fluoride sludge through the guide plate 10 until it is completely dried, so that the calcium fluoride sludge continuously turns inside the rotating drum 3, improving the drying effect of the calcium fluoride sludge.
