[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] Combined with Figure 1 A sludge drying device comprises a drying box 1, wherein the four corners of the bottom of the drying box 1 are provided with supporting legs 2, the top of the drying box 1 is provided with a feeding port 3, and the bottom end of the feeding port 3 is a long rectangular structure.

[0027] Through the above structure, the sludge directly enters the drying box 1 through the feed port 3. Since the bottom end of the feed port 3 is a long rectangular structure, the sludge can fall on the conveyor belt 5 as evenly as possible.

[0028] Combined with Figure 1 , Attachment Figure 4 and attached Figure 6 One side of the drying box 1 is provided with two motors 4 arranged up and down, and the drying box 1 is provided with conveyor belts 5 driven by the motors 4 from top to bottom. A screed plate 18 is provided above the top of the conveyor belt 5, and at least one telescopic rod 19 is provided between the top of the screed plate 18 and the inner wall of the drying box 1, and a spring 20 is provided on the telescopic rod 19.

[0029] Through the above structure, the two motors 4 drive the two conveyor belts 5 to rotate continuously, and the sludge on the conveyor belts 5 can be scraped flat by the screed plate 18, the telescopic rod 19 and the spring 20 to avoid accumulation and unevenness.

[0030] Combined with Figure 3 and attached Figure 4 The drying box 1 is provided with two sets of paired rotating shafts 6, both ends of the rotating shafts 6 are rotatably connected to the drying box 1 through bearings, and rotating rollers 7 are provided on the rotating shafts 6, and the rotating rollers 7 are connected through a conveyor belt 5.

[0031] Through the above structure, as the rotating shaft 6 rotates continuously, under the transmission connection of the conveyor belt 5, the rotating roller 7 follows the rotation, and the overall stability and transmission effect are good.

[0032] Combined with Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 The rotating shaft 6 on one side extends to one end of the drying box 1 and is connected to the output end of the motor 4. A driving wheel 8 is provided on the rotating shaft 6 on one side, and a driven wheel 9 is provided on the other side of the rotating shaft 6 extending to one end of the drying box 1. The driving wheel 8 and the driven wheel 9 are connected by a belt 10. The motor 4 is fixed to one side of the drying box 1 through a mounting frame 11.

[0033] Through the above structure, the motor 4 can be directly fixed to one side of the drying box 1 using the mounting frame 11, and the conveyor belt 5 can be rotated under the transmission connection of the driving wheel 8, the driven wheel 9 and the belt 10.

[0034] Combined with Figure 3 The motor 4 at the top drives the conveyor belt 5 at the top to rotate clockwise, and the motor 4 at the bottom drives the conveyor belt 5 at the bottom to rotate counterclockwise.

[0035] Through the above structure, since the two motors 4 rotate in different directions, the sludge directly enters the drying box 1 through the feed port 3, and the upper conveyor belt 5 rotates clockwise, and the sludge falls directly onto the lower conveyor belt 5. Since the lower conveyor belt 5 rotates counterclockwise, the sludge can be dried back and forth and directly sent to the unloading plate 17, with high drying efficiency.

[0036] Embodiment 2

[0037] Combined with Figure 2 and attached Figure 4 At least one heater 12 is provided on one side of the drying box 1, and at least one air duct 13 extending to the inside of the conveyor belt 5 is provided at the output end of the heater 12. An opening 15 is provided at the bottom end of one side of the drying box 1. A scraper 16 in contact with the bottom conveyor belt 5 is provided at the bottom end of one side of the drying box 1. A blanking plate 17 used in conjunction with the opening 15 is provided on one side of the drying box 1.

[0038] Through the above structure, the heater 12 continuously delivers hot air to the drying box 1 through the air duct 13. Since the hot air is lighter and continuously moves upward, the sludge on the conveyor belt 5 can be directly dried. Finally, under the action of the scraper 16, the sludge on the conveyor belt 5 below can be directly scraped off and all enter the unloading plate 17.

[0039] Combined with Figure 4A sloping plate 14 is provided on one side of the drying box 1 and in the middle of the conveyor belt 5 to drain the sludge so that it all falls on the conveyor belt 5 below to avoid scattering.

[0040] When the utility model is implemented:

[0041] Start the two motors 4, so that the upper motor 4 rotates clockwise and the lower motor 4 rotates counterclockwise. The motor 4 drives the rotating shaft 6 on one side to rotate continuously, and the rotating roller 7 and the driving wheel 8 rotate accordingly. Under the transmission connection of the belt 10, the other rotating shaft 6 and the rotating roller 7 rotate accordingly, so that the upper conveyor belt 5 can rotate clockwise and the lower conveyor belt 5 can rotate counterclockwise.

[0042] Start the heater 12, and hot air can be continuously delivered to the drying box 1 through the air duct 13. Since the hot air is relatively light, it continuously moves upward, is directly delivered into the drying box 1 through the feed port 3, and directly falls onto the conveyor belt 5 above. The continuously rising hot air dries the sludge. The sludge on the conveyor belt 5 can be scraped flat by the leveling plate 18, telescopic rod 19 and spring 20 to avoid accumulation and unevenness.

[0043] Then the sludge moves continuously with the upper conveyor belt 5. When it moves to the edge, it is directly led to the lower conveyor belt 5 under the action of the inclined plate 14 for further drying. The drying back and forth has a good drying effect. When the sludge moves to one side, the dried sludge can be directly scraped onto the unloading plate 17 under the action of the scraper 16.
