The blowing component 52 is located in the middle of the electric drying plate 3 and is connected to the transmission part 512. The blowing component 52 is used to accelerate the air flow speed near the electric drying plate 3. The inner cavity of the box body 1 is provided with a crushing mechanism 6 that cooperates with the electric drying plate 3. The crushing mechanism 6 includes a crushing roller 61, a rotating component 62 and a self-rotating component 63. The two groups of crushing rollers 61 are respectively located inside and outside the electric drying plate 3. The surface of the crushing roller 61 is provided with a protrusion 611 that cooperates with the electric drying plate 3. The rotating component 62 is located in the inner cavity of the box body 1 and is connected to the crushing roller 61. The rotating component 62 is used to control the crushing roller 61 to rotate around the electric drying plate 3. The self-rotating component 63 and the rotating component 62 cooperate with each other to control the crushing roller 61 to rotate while rotating around the electric drying plate 3.

[0022] During use, the electric drying plate 3 is powered on for heating, and the sludge to be dried is placed on the surface of the fixed plate 2 through the feed funnel 4. The sludge falls onto the surface of the electric drying plate 3 through the discharge hole 21 and flows from top to bottom on the surface of the electric drying plate 3. The sludge is evenly spread on the surface of the electric drying plate 3, which can effectively improve the drying effect of the sludge.

The sludge that has been preliminarily dried by the electric drying plate 3 falls to the bottom of the box body 1, and the transmission part 512 cooperates with the conveying part 511 to move the box body to the bottom of the box body. 1 The sludge at the bottom of the electric drying plate 2 is transported back to the surface of the fixed plate 2, and the sludge can flow to the surface of the electric drying plate 3 again through the discharge hole 21 for repeated drying treatment, which can effectively improve the drying effect. After the sludge is dried and attached to the surface of the electric drying plate 3, the rotating component 62 controls the two groups of crushing rollers 61 to rotate along the inside and outside of the electric drying plate 3, and the rotating component 63 controls the crushing rollers 61 to rotate while rotating around the electric drying plate 3. The protrusions 611 on the surface of the crushing rollers 61 can efficiently crush the dehydrated sludge attached to the surface of the electric drying plate 3 and clean the side walls of the electric drying plate 3.

The fan blades 522 can effectively accelerate the air flow speed near the electric drying plate 3 and effectively increase the evaporation rate of water in the sludge.

[0025] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, the conveying part 511 includes a base 5111 fixedly installed on the inner bottom wall of the box body 1, and an annular funnel-shaped structure is provided on the surface of the base 5111. A plurality of groups of fixed cylinders 5112 are fixedly installed upward at the lowest point of the surface of the base 5111, and the top of the fixed cylinder 5112 extends above the fixed plate 2. A feed port 5113 is provided at the bottom end of the side wall of the fixed cylinder 5112, and a discharge port 5114 is provided at the top end of the side wall of the fixed cylinder 5112. A rotating rod 5115 is rotatably installed between the inner top wall and the inner bottom wall of the fixed cylinder 5112, and a spiral blade 5116 is fixedly installed on the surface of the rotating rod 5115. The rotating rod 5115 is connected to the transmission part 512.

[0026] During use, the sludge flowing from the surface of the electric drying plate 3 to the bottom of the box body 1 flows into the fixed cylinder 5112 through the feed port 5113, and the transmission part 512 controls the rotating rod 5115 to rotate in the fixed cylinder 5112, thereby driving the spiral blade 5116 to rotate in the fixed cylinder 5112, and the spiral blade 5116 can conveniently push the sludge in the fixed cylinder 5112 to move upward. The sludge moves to the top in the fixed cylinder 5112 and is discharged to the surface of the fixed plate 2 through the discharge port 5114, so that the sludge can be repeatedly dried.

[0028] The rotation of the rotating rod 521 drives the transmission gear plate 5121 to rotate. The transmission gear plate 5121 engages with the control gear plate 5122 for transmission, thereby driving the control gear plate 5122 to rotate. The control gear plate 5122 drives the rotating rod 5115 to rotate in the fixed cylinder 5112.

[0030] During use, multiple groups of the fixed blocks 622 cooperate with the card slots 623 to support and position the fixed ring 627. When it is necessary to crush the sludge on the surface of the electric drying plate 3, the second motor 625 is started to drive the first fixed toothed disc 626 to rotate. The first fixed toothed disc 626 is engaged with the first gear ring 624 to drive the fixed ring 627 to rotate under the electric drying plate 3. The electric drying plate 3 drives the crushing roller 61 to rotate around the electric drying plate 3. The protrusions 611 on the surface of the crushing roller 61 can efficiently crush the dehydrated sludge attached to the surface of the electric drying plate 3 and clean the side wall of the electric drying plate 3.

[0031] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, the rotation component 63 includes a second fixed gear disc 631 fixedly connected to the top of the rotating shaft 628, and the bottom wall of the fixed plate 2 is fixedly mounted with a second gear ring 632 meshing with the second fixed gear disc 631.

[0032] The rotating shaft 628 drives the second fixed toothed disc 631 to roll along the surface of the second gear ring 632. The second fixed toothed disc 631 controls the rotating shaft 628 to rotate while rotating, thereby driving the crushing roller 61 to rotate, which can further improve the crushing effect of the sludge on the surface of the electric drying plate 3.

[0033] like Figure 1 As shown in FIG. 1 , as a preferred embodiment of the present invention, the side wall of the box body 1 is provided with ventilation holes 7, which are distributed obliquely downward from the outer wall of the box body 1 toward the inner wall of the box body 1. The ventilation holes 7 facilitate the discharge of moisture from the inner cavity of the box body 1.

[0034] The working principle of the present invention is: when in use, the electric drying plate 3 is powered on for heating, and the sludge to be dried is placed on the surface of the fixed plate 2 through the feed funnel 4. The sludge falls onto the surface of the electric drying plate 3 through the discharge hole 21 and flows from top to bottom on the surface of the electric drying plate 3. The sludge is evenly spread on the surface of the electric drying plate 3, which can effectively improve the drying effect of the sludge. The first motor 523 is started, and the first motor 523 rotates the pending rotating rod 521 to drive multiple sets of fan blades 522 to rotate in the inner cavity of the box 1. The fan blades 522 can effectively accelerate the air flow speed near the electric drying plate 3 and effectively increase the evaporation rate of water in the sludge. The rotation of the rotating rod 521 drives the transmission gear disc 5121 to rotate, and the transmission gear disc 5121 engages with the control gear disc 5122 for transmission, thereby driving the control gear disc 5122 to rotate, and the control gear disc 5122 drives the rotating rod 5115 to rotate in the fixed cylinder 5112, and the sludge at the bottom of the box body 1 flows into the fixed cylinder 5112 through the feed port 5113, and the rotating rod 5115 rotates in the fixed cylinder 5112, thereby driving the spiral blade 5116 to rotate in the fixed cylinder 5112, and the spiral blade 5116 can conveniently push the sludge in the fixed cylinder 5112 to move upward, and the sludge moves to the top in the fixed cylinder 5112 and is discharged to the surface of the fixed plate 2 through the discharge port 5114, so that the sludge can be repeatedly dried. After the sludge is dried and adheres to the surface of the electric drying plate 3, the second motor 625 is started to drive the first fixed gear disc 626 to rotate. The first fixed gear disc 626 is engaged with the first gear ring 624 to drive the fixed ring 627 to rotate under the electric drying plate 3. The electric drying plate 3 drives the crushing roller 61 to rotate around the electric drying plate 3. The protrusions 611 on the surface of the crushing roller 61 can efficiently crush the dehydrated sludge adhered to the surface of the electric drying plate 3 and clean the side wall of the electric drying plate 3.
