[0030] Example:

[0031] The present application embodiment discloses a sludge harmless drying machine, please refer to Figure 1 and Figure 2 , comprising a dryer device 1 and a mud pushing assembly 7, a chamber 2 is provided inside the dryer device 1, a plurality of groups of heating rods 3 are arranged on both sides of the chamber 2, a water inlet pipe 4 and an air outlet pipe 5 with a control valve are arranged on the top of the dryer device 1, a water outlet pipe 6 with a control valve is arranged on the bottom of the dryer device 1, one end of the water inlet pipe 4 and the air outlet pipe 5 are connected to the inside of the chamber 2, and one end of the water outlet pipe 6 is connected to the inside of the chamber 2;

[0032] The water source is heated inside the chamber 2, and the hot air is discharged from the position of the air outlet pipe 5. A plurality of groups of heating rods 3 heat the water source in the chamber 2. Since the shell of the dryer device 1 is made of heat-conducting material, the sludge in the dryer device 1 is dried when the water source in the chamber 2 is heated, so that the heat in the dryer device 1 is evenly distributed, the drying effect is improved, and the heated water source can be reused to save resources;

[0033] See also Figure 3 and Figure 4 The mud pushing assembly 7 includes a sealing ring 71 arranged on one side of the interior of the dryer device 1, and two groups of sealing rings 71 are provided. A through hole is opened on one side of the dryer device 1 and at the position corresponding to the sealing ring 71. Push-pull rods 72 are arranged inside the two sealing rings 71. A handle 73 is installed at one end of the two push-pull rods 72. The other ends of the two push-pull rods 72 penetrate and extend to the interior of the dryer device 1 and are jointly installed with a mounting plate 74. A plurality of groups of equidistant mounting cylinders 75 are installed on the lower surface of the mounting plate 74. A spring 76 is arranged inside each mounting cylinder 75. One end of each spring 76 is connected to a connecting rod 77. The connecting rod 77 is located inside the mounting cylinder 75. A mud pushing plate 78 is installed at one end of each connecting rod 77.

[0034] By setting the mud pushing assembly 7, the sludge that has not fallen from the inclined plate set at the bottom end of the dryer device 1 can be scraped to the mud discharge port to prevent the sludge from adhering to the inclined plate. The two push-pull rods 72 are both located inside the sealing ring 71 for sliding. Through the setting of the spring 76, the bottom of the mud pushing plate 78 is continuously in contact with the inclined plate at the bottom end of the dryer device 1.

[0035] The implementation principle of this embodiment is as follows: the dryer device 1 is the existing structure in the publication number CN219239500U, which includes: a box body, a support leg, a mud inlet, a motor, a rotating shaft, a rotating sheet, a conveyor belt 1, a conveyor belt 2, a heating sheet, a guide port, a scraper 1, a scraper 2, an exhaust port, a filter screen, a mesh cover, activated carbon, an inclined plate, and a mud outlet; the specific implementation method is not described in detail here;

[0036] When the sludge needs to be dried, the user opens the control valves of the water inlet pipe 4 and the air outlet pipe 5, and then transports the water source from the position of the water inlet pipe 4 to the inside of the chamber 2. At this time, the control valve at the water outlet pipe 6 is closed. After the water source is located inside the chamber 2, the user starts the heating rod 3, and several groups of heating rods 3 heat the water source in the chamber 2. The shell of the dryer device 1 is a heat-conducting material, which can dry the sludge in the dryer device 1; the water source in the chamber 2 can be reused. When the water source in the chamber 2 is released, the user only needs to open the control valve at the water outlet pipe 6 to discharge the water source in the chamber 2. The discharged water source can be used for other purposes, saving resources;

[0037] The bottom end inside the dryer device 1 is an inclined surface. In order to better discharge the sludge, when the sludge operation of the dryer device 1 is completed, the user can discharge the sludge at the bottom end of the dryer device 1 to the sludge discharge port through the mud pushing assembly 7. The user only needs to hold the handle 73 to move the push-pull rod 72 inside the sealing ring 71. At this time, the push-pull rod 72 drives the mounting plate 74 inside the dryer device 1 to move. Through the setting of the spring 76, the mud pushing plate 78 is always in contact with the inclined plate. When the mud pushing plate 78 moves, the sludge at the bottom end of the dryer device 1 is pushed toward the mud discharge port.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
