[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the sludge resource utilization brick-making device provided by this utility model; Figure 2 for Figure 1 The side sectional view shown is shown below; Figure 3 for Figure 1 The diagram shows a partial sectional view. Figure 4 for Figure 3 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 1 The diagram shows the exploded structure. Figure 6 for Figure 5The enlarged schematic diagram of part B is shown. The sludge resource utilization brick-making device includes: a supporting body 1, inside which a mixing drum 11 is installed, extending through the supporting body 1 and to its exterior; a sealing cover 12 is installed on the top of the mixing drum 11; a mixing assembly 2 is installed inside the mixing drum 11; and a scraping assembly 3 is installed outside the mixing assembly 2.

[0026] The first concave filter plate 63 and the second concave filter plate 64, installed inside the sedimentation tank 62, are used for fine filtration of the incoming wastewater. The pore sizes of the first concave filter plate 63 and the second concave filter plate 64 are different.

A solenoid valve pipe 66 is fixedly connected to the top of the tank cover 65, and its end is connected to the left side of the primary purification tank 52, responsible for introducing the pre-purified wastewater from the primary purification tank 52 into the sedimentation tank 62. When the pre-purified wastewater flows out of the solenoid valve pipe 66, it undergoes further filtration through the first concave filter plate 63 and the second concave filter plate 64, further removing impurities and achieving deep purification of the wastewater.

[0027] A circulation assembly 7 is provided on the top of the box cover 65. The circulation assembly 7 includes a pump body 71, which is installed on the top of the box cover 65. A suction tube 72 for absorbing liquid is fixedly connected to the bottom of the pump body 71. The suction tube 72 penetrates the box cover 65 and extends into it. An infusion tube 73 for discharging liquid is fixedly connected to the top of the pump body 71. A hollow circular block 74 for diverting liquid is fixedly connected to the output end of the infusion tube 73. A plurality of spray nozzles 75 for spraying are provided at the bottom of the hollow circular block 74. The outside of the spray nozzles 75 is fixedly connected to the inside of the sealing cover 12. The spray nozzles 75 penetrate the sealing cover 12 and extend to its outside.

[0028] A pump body 71, mounted on top of the tank cover 65, provides power for suction and liquid transport. A suction pipe 72 connected to the bottom of the pump body 71 extends through the tank cover 65 into the sedimentation tank 62 to absorb the liquid inside. A delivery pipe 73 at the top of the pump body 71 discharges the liquid pumped out.

When cleaning the inside of the mixing drum 11 is required, the pump body 71 can be turned on, allowing liquid to enter the mixing drum 11 from the sedimentation tank 62 via the circulation assembly 7 in a spray form for cleaning.

[0029] The working principle of the sludge resource utilization brick-making device provided by this utility model is as follows: First, the support body 1 provides stable support for the entire device. The mixing drum 11 is located inside it and extends outwards. The top sealing cover 12 ensures the sealing of the mixing environment. The drive component 21 is installed on top of the sealing cover 12 and serves as a power source, transmitting power through the round rod 24 to drive the mixing assembly 2. The round rod 24 passes through the second filter plate 32 and is rotatably connected to the first filter plate 31 and the second filter plate 32. At the same time, the arc-shaped cutter 25, the flipping plate 26, and the pushing plate 27 connected to its outer surface cut, mix, and push the sludge inside the mixing drum 11, ensuring thorough mixing. Then, during the mixing process, the wastewater in the sludge leaks down through the first filter plate 31 and the second filter plate 32 installed on the inner wall of the mixing drum 11. The synchronous plate 33 of the scraping assembly 3 rotates synchronously with the round rod 24 of the mixing assembly 2, causing the cleaning component 39 to slide into contact with the bottom of the first filter plate 31 and the top of the second filter plate 32, respectively. This prevents sludge from clogging the filter plate pores and ensures smooth drainage of wastewater. Scrapers at both ends of the synchronous plate 33 can discharge a small amount of sludge between the first filter plate 31 and the second filter plate 32 from the outlet on the right side of the mixing drum 11. The outlet has a hinged sealing door to facilitate the discharge of a small amount of sludge when the door is opened. Simultaneously, the vertical rod 34, elastic element 35, limiting block 36, ring block 37, and round tube 38 within the scraping assembly 3 cooperate to ensure stable operation of the scraping assembly 3. Finally, sludge containing a small amount of moisture is discharged from the discharge component 23 located on the right side of the mixing drum 11, completing the entire sludge treatment process.

[0030] Compared with related technologies, the sludge resource utilization brick-making device provided by this utility model has the following beneficial effects: This utility model provides a sludge resource utilization brick-making device, which uses a supporting body 1 to provide stable support for the device. A mixing drum 11 penetrates the supporting body 1 and is equipped with a top sealing cover 12, ensuring sufficient space for material mixing while effectively preventing material overflow and the entry of external debris, maintaining the airtightness of the mixing environment. The arc-shaped blades 25 inside the mixing assembly 2 ensure that the sludge inside the mixing drum 11 is properly mixed and separated, and the scraping assembly 3 further facilitates the separation of sludge and wastewater inside the mixing drum 11.
