DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0022] Example: Figure 1 As shown, an environmentally friendly solid waste treatment device includes a crushing mechanism and an extrusion mechanism. The crushing mechanism includes a crushing drum 1 and a crushing assembly 2 arranged in the crushing drum 1. The crushing assembly 2 includes a main shaft 201 and a reaming blade 202. The main shaft 201 is vertically arranged in the crushing drum 1 and is driven to rotate by the motor above. The reaming blades 202 are distributed at intervals up and down along the axis direction of the main shaft 201.

[0023] The extrusion mechanism includes a compaction box 7, an extrusion block 8 disposed in the compaction box 7, and a driving element 9 for driving the extrusion block 8. The driving element 9 is a hydraulic cylinder. A material collection port 701 is provided at the upper end of the compaction box 7, and a material removal port is provided on its side.

[0024] A material delivery pipe 6 is provided on one side of the crushing drum 1 , and the material delivery pipe 6 is connected between the crushing drum 1 and the compacting box 7 .

[0025] The compacting box 7 is arranged below the material conveying pipe 6 and is connected to the material conveying pipe 6 through a material collecting port 701 at the upper end of the compacting box 7 .

[0026] A discharge port 102 is provided at the bottom of the crushing drum 1. A filter plate 4 is located below the discharge port 102, and a liquid collection tank 5 is located below the filter plate 4. A screw conveyor assembly 3 is mounted on the filter plate 4, and the output end of the screw conveyor assembly 3 is located at the mouth of the feed pipe 6. The screw conveyor assembly 3 comprises a horizontally arranged conveying shaft and conveying blades helically wound around the conveying shaft. The front end of the conveying shaft is rotatably mounted on the crushing drum 1, and the rear end is located at the feed pipe 6. A stepper motor is installed at the end of the conveying shaft to drive its rotation.

[0027] like Figure 3 As shown, the filter plates 4 include a first filter plate 401 and second filter plates 402 positioned to the left and right of the first filter plate 401. The first filter plate 401 is a downwardly curved arc, while the second filter plate 402 is tilted, with the higher end of the second filter plate 402 connected to the inner wall of the crushing drum 1. The spiral conveyor assembly 3 is positioned within the arc of the first filter plate 401, with the length of the first filter plate 401 aligning with the axial direction of the conveyor shaft. After being crushed, the solid waste falls onto the second filter plate 402, slides along the tilt of the second filter plate 402, and then is transported by the spiral conveyor assembly 3 to the feed pipe 6.

[0028] A baffle 10 is provided at the mouth of the feed pipe 6, and the collecting port 701 of the compacting box 7 and the screw conveying assembly 3 are respectively provided at the front and rear sides of the baffle 10. A pressure control mechanism 11 is provided in the feed pipe 6, and the baffle 10 is provided on the pressure control mechanism 11.

[0029] like Figure 2 As shown, the pressure control mechanism 11 includes a cylinder 1101, a piston 1102 disposed within the cylinder 1101, a push rod 1103 fixed to the piston 1102, and a hydraulic pipe connected to the cylinder 1101. The cylinder 1101 is fixed within the feed pipe 6, the baffle 10 is fixed to the push rod 1103, and the hydraulic pipe is provided with a pressure relief valve 1106. The hydraulic pipe is divided into a first hydraulic pipe 1104 and a second hydraulic pipe 1105. The first hydraulic pipe 1104 is connected to the front end of the cylinder 1101, and the second hydraulic pipe 1105 is connected to the rear end of the cylinder 1101. The pressure relief valve 1106 is connected to the second hydraulic pipe 1105.

[0030] A limiting block is provided in the material conveying pipe 6 , and the limiting block is provided at the rear side of the baffle 10 , and the material collecting port 701 of the compacting box 7 is located between the baffle 10 and the limiting block.

[0031] When the solid waste is transported to the feed pipe 6, it is blocked by the baffle 10 and accumulates at the mouth of the feed pipe 6. As the solid waste continues to be transported, the pressure on the baffle 10 gradually increases, and the solid waste accumulated at the mouth of the feed pipe 6 begins to squeeze out the water contained in it, that is, squeeze out the waste liquid in the solid waste. When the pressure reaches the set value of the pressure relief valve 1106, the second hydraulic pipe 1105 begins to release pressure, and the baffle 10 moves backward, allowing the solid waste at the mouth of the feed pipe 6 to enter the compaction box 7 through the collection port 701 for compaction. By controlling the pressure relief value of the pressure relief valve 1106, the pressure on the baffle 10 can be controlled, thereby controlling the moisture content of the solid waste entering the compaction box 7 and increasing the compaction speed.

[0032] like Figure 1 As shown, a screening port 103 is provided on one side of the crushing drum 1, and a material retaining member 12 is provided at the screening port 103. The screening port 103 is located at the lower end of the crushing drum 1 and corresponds to the height of the reamer blade 202 at the lower end of the main shaft 201. The material retaining member 12 is arranged vertically. The material retaining member 12 is a metal retaining rod.

[0033] A baffle plate 104 for closing the screening port 103 is provided at the screening port 103. The upper end of the baffle plate 104 is hinged to the wall of the crushing cylinder 1 through a hinge shaft. An elastic reset member is provided between the baffle plate 104 and the wall of the crushing cylinder 1. The elastic reset member is a spring. One end of the spring is connected to the baffle plate 104, and the other end is connected to the outer wall of the crushing cylinder 1.

[0034] The reamer blade 202 is divided into a first reamer blade 202a and a second reamer blade 202b. The first reamer blade 202a is tilted and the second reamer blade 202b is horizontal. The second reamer blade 202b is arranged at the lower end of the main shaft 201 and is located between the upper and lower stoppers 12.

[0035] like Figure 4 As shown, the main shaft 201 is provided with a pusher mechanism, which includes a telescopic handle 203 and a telescopic rod 204. Both the telescopic handle 203 and the telescopic rod 204 are hydraulic cylinders, and the two are connected by a hydraulic pipeline 206. The telescopic handle 203 is fixedly connected to the main shaft 201, and the second reaming blade 202b is hinged to the telescopic handle 203. One end of the telescopic rod 204 is hinged to the main shaft 201, and the other end is hinged to the reaming blade 202. The front end of the telescopic handle 203 is equipped with a mounting head 205, and the second reaming blade 202b is hinged to the mounting head 205 and can rotate horizontally relative to the mounting head 205. The mounting head 205 is provided with a limit plate on the front side of the main shaft 201 in the direction of rotation to prevent the second reaming blade 202b from rotating forward. A return spring 207 is provided between the mounting head 205 and the cylinder of the telescopic handle 203. When the telescopic handle 203 is extended, the return spring 207 pulls the mounting head 205 backwards, causing the telescopic handle 203 to retract.

[0036] During the crushing process, ordinary solid waste will be blocked by the material blocking member 12 at the screening port 103 of the crushing drum 1, and the second reamer blade 202b will cut the solid waste into pieces after passing through. When encountering hard, difficult-to-crush solid waste, the solid waste will be blocked by the material blocking member 12 at the screening port 103 of the crushing drum 1. When the second reamer blade 202b passes through, the second reamer blade 202b is swung backward by the resistance of the solid waste, and at the same time drives the telescopic rod 204. The hydraulic pressure in the telescopic rod 204 enters the telescopic handle 203, causing the telescopic handle 203 to extend, and the mounting head 205 and the second reamer blade 202b move toward the screening port 103. At this time, the backward-tilted second reamer blade 202b acts as a pusher to push the solid waste out of the screening port 103, completing the solid waste screening.
