The squeezed sewage is uniformly collected by the collection frame 401, and the plug-in connection between the protrusions 402 and the grooves 403 facilitates the regular disassembly of the collection frame 401 and the removal of the sewage.

[0032] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 A second electric push rod 17 is fixedly mounted on the inner top wall of the treatment box 1. A second extrusion plate 16 is fixedly mounted on the output end of the second electric push rod 17. A guide assembly 18 is provided between the second extrusion plate 16 and the treatment box 1. The guide assembly 18 includes two sets of guide rods 1802, which are vertically mounted at both ends of the top of the second extrusion plate 16. The tops of both sets of guide rods 1802 extend out of the treatment box 1. The top of the treatment box 1 is provided with guide holes 1801 that match the guide rods 1802. When the second extrusion plate 16 moves, it can drive the guide rods 1802 to slide within the guide holes 1801, thereby making the second extrusion plate 16 more stable when raised and lowered. A first extrusion plate 15 is installed at the end of the treatment box 1 near the second extrusion plate 16. A gap is provided between the first extrusion plate 15 and the treatment box 1. This allows the extruded sewage to fall into the collection assembly 4 through the gap.

[0033] Please refer to the attached figure in the instruction manual Figure 1 A pusher assembly 3 is provided between the first extrusion plate 15 and the treatment box 1. The pusher assembly 3 includes a housing 301, which is mounted on the left side of the treatment box 1. A first electric push rod 302 is fixedly mounted inside the housing 301.

The first electric push rod 302 extends, driving the push plate 303 to move rightward, thereby pushing the sludge to the right.

[0034] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2A heating box 11 is installed on the right side of the treatment box 1. Support columns 9 are connected to the bottoms of the treatment box 1 and the heating box 11.

By opening the door 19, it is convenient to treat the sewage inside the treatment box 1. Through the observation window 20, it is convenient to observe the working conditions inside the heating box 11 at any time.

[0035] Please refer to the attached figure in the instruction manual Figure 1 A feed port 13 is provided at the left end of the top of the heating box 11, and a discharge port 14 is provided at the right end of the treatment box 1 near the feed port 13. A heating block 12 is mounted on the inner top wall of the heating box 11, and a discharge port 8 is provided at the bottom of the heating box 11.

The arrangement of the two sets of guide plates 5 allows the heated sludge to be quickly discharged from the heating box 11, and the arrangement of the heating wires 6 further heats the sludge, thereby increasing the heating and evaporation rate of the sludge.

[0036] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A solenoid valve 7 is installed at the bottom of the discharge port 8. A stirring assembly 10 is provided on the processing box 1. The stirring assembly 10 includes a stirring shaft 1002, which is rotatably connected to the interior of the heating box 11 through a bearing. A drive motor 1001 is installed on the right side of the heating box 11. The power output end of the drive motor 1001 is fixedly connected to the right end of the stirring shaft 1002. A plurality of stirring rods 1003 are fixedly connected to the top and bottom of the stirring shaft 1002. When the drive motor 1001 is in operation, the stirring rods 1003 are driven to rotate through the stirring shaft 1002, thereby causing the sludge to roll, thereby achieving efficient heating and evaporation of the sludge.

[0037] Working principle: When in use, the sludge is first discharged into the interior of the treatment box 1 from the feed pipe 2 at the upper end of the treatment box 1. At this time, the sludge falls on the first extrusion plate 15, and then the first electric push rod 302 is controlled to extend. The first electric push rod 302 extends to push the push plate 303 to move to the right, and then pushes the sludge to move between the first extrusion plate 15 and the second extrusion plate 16. Then the first electric push rod 302 is retracted to drive the push plate 303 to reset. At this time, the second electric push rod 17 is controlled to extend. The second electric push rod 17 extends to drive the second extrusion plate 16 to move downward. The moisture in the sludge can be squeezed out by the mutual squeezing of the first extrusion plate 15 and the second extrusion plate 16, and discharged into the interior of the collection frame 401 through the gap between the first extrusion plate 15 and the treatment box 1 for collection.

[0038] Then the first electric push rod 302 is controlled to extend again, and the extension of the first electric push rod 302 drives the push plate 303 to move to the right. The right movement of the push plate 303 drives the treated sludge to move to the right until the sludge passes through the discharge port 14 and the feed port 13 and falls into the interior of the heating box 11. Then the heating wire 6, the drive motor 1001 and the heating block 12 are turned on, and the heating wire 6 and the heating block 12 heat and evaporate the sludge. When the drive motor 1001 is working, the stirring rod 1003 is driven to rotate through the stirring shaft 1002, thereby stirring the sludge and realizing the sludge tumbling, so that the sludge can be efficiently heated and evaporated, further improving the sludge treatment efficiency of the device.

[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
