Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge treatment device for preparing nutrient soil. Background Technology

[0002] Sludge is rich in nutrients such as nitrogen, phosphorus, and potassium, which are essential for plant growth. It is a potential high-quality raw material for preparing nutrient soil. Nutrient soil prepared from sludge can effectively improve the structure and fertility of barren soil. For farmland with soil compaction and declining fertility due to long-term over-cultivation, the application of this nutrient soil can significantly improve the soil's aeration and water retention. It is widely used in landscaping, soil improvement, and organic agriculture to achieve the sustainable utilization of waste.

[0003] Sludge contains a large number of microorganisms, including pathogens, parasite eggs, and various harmful bacteria. In the process of turning sludge into nutrient soil, it is necessary to disinfect the sludge. Most current sludge treatment devices use high-temperature disinfection. To ensure that various stubborn microorganisms in the sludge can be completely killed, the sludge often needs to be dried for a long time. Long-term drying not only consumes a lot of energy, but also affects the sludge treatment efficiency. Therefore, we provide a sludge treatment device for preparing nutrient soil. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] First Embodiment

[0030] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 With appendix Figure 5 As shown: A sludge treatment device for preparing nutrient soil includes a treatment box 1, a filter frame 2 disposed inside the treatment box 1, and an ultraviolet lamp group 3 disposed at the top of the inside of the treatment box 1. The ultraviolet lamp group 3 can irradiate the sludge inside the filter frame 2 to achieve the effect of sterilization.

[0031] The flipping assembly 4, positioned above the filter frame 2, includes a hanging plate 401 at the top of the filter frame 2, a mounting plate 402 below the hanging plate 401, a set of bidirectional shovels 403 below the mounting plate 402, and a moving structure above the hanging plate 401. The flipping assembly 4 includes a set of motors 404 mounted on the upper surface of the hanging plate 401. Each motor 404 has a drive gear 405 mounted at its output end, and each drive gear 405 has a toothed plate 406 meshing above it. The left and right ends of each toothed plate 406 are connected to the inner wall of the processing box 1. The two motors 404 are controlled to reciprocate synchronously in the same direction. The motors 404 drive the drive gears 405 to rotate, and simultaneously the drive gears 405 move on the toothed plates 406. 01 will move the bidirectional shovel 403, which can turn the sludge horizontally to the left and right, so that the sludge can be evenly irradiated and sterilized. A set of support rods 407 are slidably connected to the hanging plate 401. The left and right ends of each support rod 407 are connected to the inner wall of the treatment box 1. The support rods 407 can support the hanging plate 401, so that the toothed plate 406 and the drive gear 405 can be stably meshed, ensuring the stability of the hanging plate 401 when it moves. A set of retaining rings 408 are fixedly connected to the outer surface of each support rod 407. Each set of retaining rings 408 is symmetrically arranged. The retaining rings 408 can limit the movement of the hanging plate 401, so as to prevent the bidirectional shovel 403 from moving too far inside the filter frame 2 and colliding.

[0032] The pushing structure set between the hanging plate 401 and the mounting plate 402 includes an electric push rod 409 installed on the bottom surface of the hanging plate 401 and a set of hanging frames 410 fixedly connected to the bottom surface of the hanging plate 401. The inner walls of the two hanging frames 410 are slidably connected to a U-shaped plate 411. The bottom end of the U-shaped plate 411 is connected to the upper surface of the mounting plate 402. The telescopic end of the electric push rod 409 is connected to the upper surface of the U-shaped plate 411. By controlling the electric push rod 409 to reciprocate to extend and retract, the U-shaped plate 411 will gradually drive the bidirectional shovel plate 403 to move in the front and back horizontal direction. The bidirectional shovel plate 403 will further turn over the sludge, which can spread the sludge evenly. The ultraviolet lamp group 3 will then irradiate the sludge evenly to sterilize it.

[0033] A set of equally spaced support plates 412 are fixedly connected to the upper surface of the hanging plate 401. Each support plate 412 is equipped with a wiping cotton 413 at its top. When the hanging plate 401 moves, the support plates 412 will move the wiping cotton 413 in sync. The wiping cotton 413 will wipe the outer surface of the ultraviolet lamp group 3, which can effectively remove the sludge particles, dust and other pollutants attached to the surface of the ultraviolet lamp group 3, and ensure that the light transmittance of the ultraviolet lamp group 3 is always kept at a high level.

[0034] Second Embodiment

[0035] As attached Figure 1 Appendix Figure 2 With appendix Figure 6 As shown: The support assembly 5 is installed inside the processing box 1 and is used to support the filter frame 2. The support assembly 5 includes two sets of hydraulic push rods 501 installed on the inner wall of the processing box 1. The telescopic ends of the two sets of hydraulic push rods 501 are jointly installed with I-shaped plates 502. The I-shaped plates 502 can support the filter frame 2. When the hydraulic push rods 501 work, they can push the filter frame 2 to rise. At the same time, the bidirectional shovel 403 will be inserted into the sludge, which is conducive to the subsequent turning of the sludge. A set of positioning plates 503 is fixedly connected to the upper surface of the I-shaped plate 502. Anti-collision pads are provided on the side of the two positioning plates 503 that are close to each other. The positioning plates 503 can stabilize the filter frame 2 on the I-shaped plate 502 and prevent the filter frame 2 from sliding.

[0036] Third Embodiment

[0037] As attached Figure 1 With appendix Figure 2As shown: A collection hood 6 is fixedly connected to the inner wall of the treatment box 1. The bottom end of the collection hood 6 is connected to a discharge pipe 7, and the bottom end of the discharge pipe 7 extends to the bottom of the treatment box 1. The collection hood 6 can be used to collect residual water in the sludge. During the process of the bidirectional shovel 403 turning the sludge, the free water in the sludge will be squeezed out and collected to a lower position through the inclined design of the collection hood 6. The discharge pipe 7 connected to the bottom of the collection hood 6 will discharge the collected water to the outside of the device, which not only reduces the water content of the sludge but also improves the efficiency of subsequent treatment. A square frame 8 is fixedly connected to the bottom surface of the treatment box 1. The bottom surface of the square frame 8 is provided with anti-slip texture. The square frame 8 can be used to support the treatment box 1, so that there is a certain distance between the discharge pipe 7 and the ground, which makes it convenient for the staff to collect and treat the water discharged from the discharge pipe 7.

[0038] Working principle: First, sludge is added into the filter frame 2. Then, the hydraulic push rod 501 is extended, and the I-shaped plate 502 pushes the filter frame 2 upward. The bidirectional shovel 403 is then placed inside the filter frame 2. Next, the motor 404 is controlled to reciprocate synchronously in the same direction, which drives the drive gear 405 to rotate synchronously. The drive gear 405 moves on the toothed plate 406, and the hanging plate 401 and the bidirectional shovel 403 move inside the filter frame 2 to shovel the sludge. At the same time, the electric push rod 409 is controlled to reciprocate, and the electric push rod 409 pushes the U-shaped plate 411 to move back and forth. The bidirectional shovel 403 further turns the sludge, which can spread the sludge evenly. The ultraviolet lamp group 3 will then irradiate the sludge evenly to sterilize it, further reducing the sterilization time and improving the sterilization efficiency.
