[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Such as Figures 1-7As shown in the figure, the utility model provides a technical solution: an energy-saving belt-type sludge drying device, which includes a drying treatment bin 1 and a breathable conveyor belt 13. The breathable conveyor belt 13 is arranged in the inner cavity of the drying treatment bin 1. A feed pipe opening 11 is fixedly connected to the top of the drying treatment bin 1. A strip-shaped pipe 17 is fixedly installed at the bottom of the inner wall of the drying treatment bin 1. A hot gas output pipe 18 is fixedly connected to the top of the strip-shaped pipe 17. A turning mechanism 2 is arranged on the drying treatment bin 1. The turning mechanism 2 includes a limiting side plate one 21 and a limiting side plate two 22. The limiting side plate one 21 is fixedly installed on the front side of the inner wall of the drying treatment bin 1, and the limiting side plate two 22 is fixedly installed on the back side of the inner wall of the drying treatment bin 1. An inclined platform 23 is fixedly installed between the adjacent sides of the limiting side plate one 21 and the limiting side plate two 22. The right side of the inclined platform 23 is movably connected with a receiving frame 24. A through groove 25 is opened at the bottom of the receiving frame 24. An extension platform 26 is fixedly installed on the right side of the limiting side plate one 21. A driving motor 261 is fixedly installed on the top of the extension platform 26. The output shaft of the driving motor 261 extends to the bottom of the extension platform 26 and is fixedly connected with a cam 262. With the cooperation of the limiting side plate one 21 and the limiting side plate two 22, the sludge at the top edge of the breathable conveyor belt 13 can be guided to the inclined platform 23, and then through the inclined platform 23, the sludge passing through the top of the breathable conveyor belt 13 can be lifted and guided, so that the sludge falls into the inner cavity of the receiving frame 24. Control the driving motor 261 to work to drive the cam 262 to rotate. The cam 262 pushes the receiving frame 24 to continuously move back and forth, prompting the sludge to scatter from the bottom of the through groove 25 to the top of the breathable conveyor belt 13, realizing the function of turning the material and improving the sufficiency of sludge drying.

[0025] As an implementation manner in this embodiment, as Figure 3 , Figure 4 , Figure 5 shown, track blocks 27 are fixedly installed on the right sides of both the limiting side plate one 21 and the limiting side plate two 22. A sliding arm 28 is slidably connected to the outer wall of the track block 27. The end of the sliding arm 28 is fixedly installed with a receiving frame 24. A fixing block 29 is fixedly installed on the right side of the limiting side plate two 22. A second elastic member 291 is fixedly installed on the front side of the fixing block 29. The front side of the second elastic member 291 is fixedly connected to the back side of the sliding arm 28. The sliding arm 28 can slide back and forth on the outer wall of the track block 27, thereby limiting the receiving frame 24 to move back and forth. When the cam 262 rotates to a certain angle and pushes the sliding arm 28 and the receiving frame 24 to move backward, the second elastic member 291 can be compressed. After the cam 262 continues to rotate and releases the thrust on the receiving frame 24, through the initial elastic force of the second elastic member 291, the receiving frame 24 can be driven to slide forward and reset, and then the receiving frame 24 can perform repeated back-and-forth movement work.

[0026] As an implementation manner in this embodiment, as Figure 2 ,Figure 6 , Figure 7 As shown in Figure 7 , at the top of the inner wall of the drying treatment bin 1, an exhaust mesh plate 12 is fixedly installed. At the top of the inner wall of the drying treatment bin 1, an initial baffle 14 is fixedly installed. Between the front and back of the inner wall of the drying treatment bin 1, a spreading plate 15 is fixedly installed. At the bottom of the inner wall of the drying treatment bin 1, a wind baffle 16 is fixedly installed. On the inner wall of the hot air output pipe 18, a fixed square plate 183 is fixedly installed. At the top of the fixed square plate 183, a sliding square plate 181 is movably connected. The outer wall of the sliding square plate 181 is slidably connected to the inner wall of the hot air output pipe 18. On the top of the sliding square plate 181, a dispersion groove 182 is opened. On the top of the fixed square plate 183, a middle position groove 184 is opened. On the inner wall of the hot air output pipe 18, a support frame 185 located below the fixed square plate 183 is fixedly installed. On the top of the support frame 185, a first elastic member 186 is fixedly installed. The top of the first elastic member 186 is fixedly connected to the bottom of the sliding square plate 181. Through the gap design between the bottom of the spreading plate 15 and the top of the breathable conveyor belt 13, the sludge can be leveled. The output end of an externally connected hot air blower is pre-connected to the bottom of the strip-shaped pipe 17. By controlling the externally connected hot air blower to work, hot air can be conveyed into the inner cavity of the strip-shaped pipe 17. Then, the hot air sprays out from the top of the hot air output pipe 18 to dry the sludge on the top of the breathable conveyor belt 13. When the externally connected hot air blower works, the generated thrust can push the sliding square plate 181 to stretch the first elastic member 186 and slide upward, and then the hot air is output through the inner cavities of the middle position groove 184 and the dispersion groove 182. After the externally connected hot air blower stops working, through the initial elastic force of the first elastic member 186, the sliding square plate 181 is driven to fit on the top of the fixed square plate 183 to seal the inner cavity of the hot air output pipe 18, avoiding the problem that impurities are likely to fall during maintenance and cause blockage of the inner cavities of the hot air output pipe 18 and the strip-shaped pipe 17.

[0027] Working principle: During use, the sludge is put in from the top of the feed pipe orifice 11. By controlling the breathable conveyor belt 13 to work, the sludge can be transported to the right. The output end of an externally connected hot air blower is pre-connected to the bottom of the strip-shaped pipe 17. By controlling the externally connected hot air blower to work, hot air can be conveyed into the inner cavity of the strip-shaped pipe 17. Then, the hot air sprays out from the top of the hot air output pipe 18 to dry the sludge on the top of the breathable conveyor belt 13. The inclined table plate 23 can lift and guide the sludge passing through the top of the breathable conveyor belt 13, so that the sludge falls into the inner cavity of the receiving frame 24. By controlling the driving motor 261 to work, the driving cam 262 rotates. The receiving frame 24 is pushed by the cam 262 to continuously move back and forth, prompting the sludge to fall from the bottom of the through slot 25 to the top of the breathable conveyor belt 13, realizing the function of turning the material. The fully dried material will leak out from the bottom of the drying treatment bin 1.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
