[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] like Figure 1-Figure 2 As shown, the present application provides a sludge drying equipment, including a drying box 1, a support frame 12 is fixedly installed on the outside of the drying box 1, and a discharge port 11 is provided at the bottom of the drying box 1, through which the dried material is discharged outwardly. At the same time, a hot air blower 13 is also fixedly installed on one side of the drying box 1, and the air outlet of the hot air blower 13 is connected to the drying box 1 by a pipeline, thereby providing hot air to the drying box 1.

[0031] like Figure 2-Figure 3 and Figure 5 As shown, a feeding mechanism 2 is provided on one side of the drying box 1. The feeding mechanism 2 has a feeding box 21 fixedly mounted on one side of the drying box 1. A feeding port is provided at the upper end of the feeding box 21, and a delivery pipe 23 is connected to the lower end of the feeding box 21. The delivery pipe 23 is connected to the drying box 1, so that the material in the feeding box 21 is delivered to the drying box 1 through the delivery pipe 23.

[0032] The axis of the feeding pipe 23 is rotatably connected to a screw 24, and a plurality of spiral pieces 25 are fixedly installed on the outside of the screw 24. The spiral pieces 25 are attached to the surface of the feeding pipe 23 to drive the screw 24 to rotate. Figure 3 As shown, a mounting bracket 22 is fixedly installed on one side of the feed box 21, a drive motor 26 is fixedly installed on the mounting bracket 22, and one end of the screw 24 protrudes from the feed pipe 23, and a rotating shaft 27 is fixedly installed on the protruding end of the screw 24. In the present application, the drive motor 26 and the rotating shaft 27 are driven by a sprocket chain structure, so starting the drive motor 26 can drive the rotating shaft 27 and the screw 24 to rotate, thereby rotating the spiral blade 25 to push the material into the drying box 1.

[0033] In order to discharge the sewage in the sludge during the feeding process, Figure 5 As shown, a filter hole 28 is provided at the bottom of the feed pipe 23, and a water trough 29 is fixedly installed at the lower end of the feed pipe 23. The water trough 29 is located below the filter hole 28, and one end of the water trough 29 is connected to a drain pipe 291. Therefore, when the spiral blade 25 rotates the sludge, the sewage carried in the sludge will be filtered through the filter hole 28, thereby reducing the moisture of the sludge entering the drying box 1 and accelerating the drying speed. The filtered sewage will be discharged outward through the drain pipe 291.

A second conveyor belt 15 is also fixedly installed inside the drying box 1, and the second conveyor belt 15 is located below the first conveyor belt 14. In this application, the first conveyor belt 14 and the second conveyor belt 15 are installed crosswise, so when the sludge reaches the tail end of the first conveyor belt 14, it will fall onto the second conveyor belt 15, thereby changing the heating surface of the sludge and improving the drying efficiency.

[0035] In summary: when drying sludge, the sludge to be dried is added to the feed box 21, and the spiral blades 25 can break up the larger pieces of sludge and convey the sludge toward the first conveyor belt 14;

[0036] At the same time, the sewage in the sludge will be filtered into the water tank 29 through the filter hole 28 and then discharged outward. The sludge is dried by the first conveyor belt 14 and the second conveyor belt 15, and finally discharged outward through the discharge port 11, thereby realizing continuous drying treatment of the sludge, filtering and separating the moisture in the sludge in advance, thereby shortening the drying time, reducing energy consumption, and preventing the sludge from clogging the pipeline.
