[0024] The wastewater reuse separation device of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0025] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0026] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a wastewater reuse separation device, including a separation cylinder 1, a separation roller 2, and a drive motor 3.

[0027] Specifically, a feed trough 4 is fixedly provided at the top of the separation cylinder 1, and the feed trough 4 is used to transport wastewater to the separation roller 2.

[0028] The separating roller 2 is rotatably mounted on the separating cylinder 1. The separating roller 2 has a regular polygonal cross-section and has multiple filter gaps 5.

[0029] The drive motor 3 is fixedly installed on the outer wall of the separating cylinder 1, and the drive motor 3 is connected to the separating roller 2 in a transmission manner.

[0030] In this embodiment, wastewater flows into the upper part of the separating roller 2 through the feed trough 4, and the wastewater and solid waste flow into the lower part of the separating cylinder 1 through the filter gap 5. The wastewater and solid waste are blocked on the separating roller 2, and the separating roller 2 rotates under the drive of the drive motor 3. The wastewater and solid waste located on the separating roller 2 are discharged during the rotation of the separating roller 2, which effectively reduces the accumulation of wastewater and solid waste on the separating roller 2, thereby greatly improving the separation efficiency of wastewater and solid waste.

[0031] In one specific embodiment, the top of the separation cylinder 1 is provided with an arc-shaped isolation cavity 6, and the separation roller 2 is in close and sliding contact with the inner wall of the isolation cavity 6. During rotation, the separation roller 2 is in close and sliding contact with the inner wall of the isolation cavity 6, which effectively prevents wastewater and solid waste from falling from the separation roller 2 to the bottom of the separation cylinder 1, thereby ensuring the separation effect of wastewater and solid waste.

[0032] Furthermore, the separating roller 2 includes a drive connecting shaft 7 and multiple filter frames 8.

[0033] Specifically, the transmission connecting shaft 7 is rotatably mounted on the separating cylinder 1, and the transmission connecting shaft 7 is connected to the drive motor 3 in a transmission manner.

[0034] The filter frame 8 is in the shape of a regular polygon. The filter frame 8 is fixedly mounted on the transmission connecting shaft 7 by the mounting post 9, and the filter frame 8 is in close contact with the inner wall of the isolation cavity 6.

[0035] In this embodiment, the filter frames 8 are evenly distributed on the transmission connecting shaft 7, and there is a filter gap 5 between two adjacent filter frames 8. When wastewater enters the separation roller 2, the wastewater flows through the filter gap 5 into the lower part of the separation cylinder 1. The wastewater and solid waste are blocked on the filter frames 8. During the rotation of the filter frames 8, the wastewater and solid waste located on the filter frames 8 slide off the filter frames 8 and fall to the outside of the separation cylinder 1.

[0036] The outer wall of the bend in the filter frame 8 is designed in an arc shape. During the rotation of the separating roller 2, the arc shape of the outer wall of the bend in the filter frame 8 reduces wear between the filter frame 8 and the inner wall of the isolation chamber 6, thereby improving the service life of the separating roller 2.

[0037] Furthermore, a separation comb is fixedly installed on the separation cylinder 1, and the separation comb is arranged opposite to the feed trough 4. The separation comb is in close contact with the inner wall of the filter gap 5 and slides in contact with it.

[0038] Specifically, the separating comb includes a connecting strip 10 and comb teeth 11. The connecting strip 10 is fixedly installed on the separating cylinder 1. Multiple comb teeth 11 are provided. The comb teeth 11 are fixedly connected to the connecting strip 10, and the comb teeth 11 are in close contact with the inner wall of the filter gap 5.

[0039] When the separating comb is installed, the connecting strip 10 is fixedly installed on the separating cylinder 1 in an inclined shape, and the end of the connecting strip 10 away from the comb teeth 11 extends to the outside of the separating cylinder 1.

[0040] During the wastewater-solid waste separation process, as the separating roller 2 rotates, the comb teeth 11 insert into the filter gap 5 and slide against the inner wall of the filter gap 5. After the wastewater-solid waste on the separating roller 2 is blocked by the comb teeth 11, it slides off the filter frame 8 along the surface of the comb teeth 11, effectively reducing the accumulation of wastewater-solid waste on the filter frame 8, thereby greatly improving the separation efficiency of wastewater-solid waste.

[0041] Compared with the prior art, the present invention has at least the following beneficial effects:

[0042] This invention utilizes a separating roller to separate and filter solid waste in wastewater. Simultaneously, the filtered solid waste is discharged through the rotation of the separating roller, effectively preventing the accumulation of solid waste in the wastewater on the separating roller and greatly improving the filtration efficiency of solid waste in wastewater. It features a simple structure and convenient operation.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
