Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a waste debris-liquid-sludge-water separation device. Background Technology

[0002] Waste-liquid-slag-water separation devices are widely used in machining, metal processing and other fields to separate solid impurities such as metal chips and aluminum chips from cutting fluids, so as to improve the recycling rate of cutting fluids and reduce environmental pollution. They are usually separated by direct filtration with a filter screen.

[0003] Patent CN221244139U discloses a high-efficiency slag-water separation and collection device, including a water tank, an inlet pipe at the top of the water tank, an installation frame fixedly connected to the inner wall of the water tank and positioned below the inlet pipe, a slag-water separation screen fixedly connected to the top of the installation frame and tilted to the right, a slag collection box inside the water tank and positioned below the slag-water separation screen, and a hand-cranked lifting device outside the water tank, with the output end of the hand-cranked lifting device fixedly connected to the slag collection box.

[0004] This high-efficiency slag-water separation and collection device only uses a slag-water separation screen to separate waste chips, liquids, and slags. If the screen openings are too small, due to only one stage of filtration, most of the waste residue will remain on the screen and cannot be effectively dispersed, easily causing screen blockage. To avoid blockage, the screen opening diameter must be increased. However, smaller-diameter waste chips cannot be filtered and retained, resulting in incomplete separation. Therefore, a multi-stage waste chip-liquid-slag-water separation device is needed to prevent excessive waste residue from clogging the first-stage separation screen and to improve the separation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a waste-liquid-sludge-water separation device that can filter waste-liquid-sludge multiple times, thereby increasing the filtration effect.

[0006] To achieve the above objectives, this utility model provides a waste-liquid-sludge-water separation device. This device includes an inclined primary filter bed, with a primary filter plate at its front end, forming a liquid flow gap between the primary filter plate and the bottom surface of the primary filter bed. Multiple drain ports are located at the bottom of the rear end of the primary filter bed, and secondary filter cups are connected to the bottom of these drain ports via drain pipes. A secondary annular filter plate is located in the middle of each secondary filter cup, and a central tube penetrating the secondary annular filter plate is inserted into the secondary filter cup. The upper end of the central tube extends to the upper end of the secondary filter cup and connects to the drain pipe, while the lower end of the central tube forms a sedimentation gap with the bottom of the secondary filter cup. A liquid outlet conduit is located on the side of the secondary filter cup above the secondary annular filter plate. A tertiary filter box is mounted on the bottom of the primary filter bed via a bracket. The tertiary filter box has multiple openings on its rear side communicating with the liquid outlet conduits and a discharge pipe on its front side. At least one filtration layer is disposed inside the tertiary filter box.

[0007] Preferably, the secondary annular filter plate includes an upper fixing ring and a lower fixing ring disposed at both ends, and a plurality of barrier strips are disposed between the upper fixing ring and the lower fixing ring along the circumferential direction.

[0008] Preferably, the upper end of the central tube is provided with a quick-connect fitting, and the bottom of the drain tube is provided with a quick-connect interface that mates with the quick-connect fitting, and the central tube and the drain tube are connected by insertion.

[0009] Preferably, the bottom of the secondary filter cup is provided with a cup bottom shell; the cup bottom shell is spirally connected to the main body of the secondary filter cup.

[0010] Preferably, a baffle plate is provided around the primary filter bed.

[0011] Preferably, a support column is provided at the bottom of the primary filter bed.

[0012] Preferably, a slag-blocking plate perpendicular to the rear end of the primary filter plate is provided.

[0013] According to the above technical solution, this utility model provides a waste-liquid-sludge-water separation device. The device includes an inclined primary filter bed, with a primary filter plate at the front end and a liquid flow gap between the primary filter plate and the bottom surface of the primary filter bed. Multiple drain ports are located at the rear bottom of the primary filter bed, and a secondary filter cup is connected to the bottom of each drain port via a drain pipe. A secondary annular filter plate is located in the middle of the secondary filter cup, and a central tube is inserted into the secondary filter cup, penetrating the secondary annular filter plate. The upper end of the central tube extends to the upper end of the secondary filter cup and connects to the drain pipe. A sedimentation gap is formed between the lower end of the central tube and the bottom of the secondary filter cup. A liquid outlet conduit is located on the side of the secondary filter cup above the secondary annular filter plate. A tertiary filter box is mounted on the bottom of the primary filter bed via a bracket. The tertiary filter box has multiple openings on its rear side communicating with the liquid outlet conduit and a discharge pipe on its front side. At least one filtration layer is located inside the tertiary filter box.

[0014] The separation process and beneficial effects of the waste-liquid-sludge-water separation device are as follows: The waste-liquid-sludge-water is discharged onto a primary filter bed, where it undergoes a first-stage filtration process, filtering out larger particles of impurities and retaining them on the primary filter plate. Then, the waste-liquid-sludge-water after primary filtration flows through a drain outlet into multiple secondary filter cups, flowing along the secondary filter cups into the sedimentation gaps, and then flowing upwards back through a secondary annular filter plate for a second-stage filtration, further filtering out smaller particles of impurities and retaining them in the sedimentation gaps. Finally, the waste-liquid-sludge-water flows through an outlet pipe into a tertiary filter box, where it undergoes a third-stage filtration process through a filter layer. The finally filtered waste-liquid-sludge-water flows out through a discharge pipe to the desired location.

[0015] The filtration radius of the primary filter plate, the secondary annular filter plate, and the filter layer gradually decreases. Through this three-stage filtration method, the problem of impurities of different diameter ranges being left in the same filtration position, which can easily cause blockage, is avoided in traditional filtration, thus increasing the filtration effect.

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0027] See Figure 1-5The waste-liquid-sludge-water separation device shown includes an inclined primary filter bed 1. A primary filter plate 2 is located at the front end of the primary filter bed 1, and a liquid flow gap is formed between the primary filter plate 2 and the bottom surface of the primary filter bed 1. Multiple drain ports 12 are located at the rear bottom of the primary filter bed 1. The bottom of each drain port 12 is connected to a secondary filter cup 6 via a drain pipe 5. A secondary annular filter plate 15 is located in the middle of the secondary filter cup 6, and a central tube 16 is inserted into the secondary filter cup 6, penetrating the secondary annular filter plate 15. The upper end of the tube 16 extends to the upper end of the secondary filter cup 6 and connects to the drain pipe 5. The lower end of the central tube 16 forms a sedimentation gap with the bottom of the secondary filter cup 6. The side of the secondary filter cup 6 is provided with an outlet conduit 8 above the secondary annular filter plate 15. The bottom of the primary filter bed 1 is equipped with a tertiary filter box 9 through a bracket 10. The rear side of the tertiary filter box 9 is provided with multiple openings communicating with the outlet conduit 8, and the front side is provided with a discharge pipe 14. The tertiary filter box 9 is provided with at least one filter layer 13.

[0028] Through the implementation of the above technical solution, during use, waste liquid and sludge are discharged onto the primary filter bed 1. The primary filter plate 2 on the primary filter bed 1 performs the first filtration, filtering out larger particles of impurities and leaving them on the primary filter plate 2. Then, the waste liquid and sludge after primary filtration flows into multiple secondary filter cups 6 through the drain port 12, flows along the secondary filter cups 6 into the sedimentation gap, and then flows back upwards to undergo a second filtration through the secondary annular filter plate 15, further filtering out smaller particles of impurities and leaving them in the sedimentation gap. Finally, the waste liquid and sludge flow into the tertiary filter box 9 through the outlet pipe 8, where it undergoes a third filtration through the filter layer 13. The finally filtered waste liquid and sludge flows out to the desired location through the discharge pipe 14. The filtration radii of the primary filter plate 2, the secondary annular filter plate 15, and the filter layer 13 gradually decrease. This three-stage filtration method avoids the problem of impurities of different diameter ranges being left in the same filtration position, which can easily cause blockage, thus increasing the filtration effect.

[0029] In this embodiment, the secondary annular filter plate 15 includes an upper fixing ring 18 and a lower fixing ring 17 disposed at both ends, with a plurality of barrier strips 19 arranged circumferentially between the upper fixing ring 18 and the lower fixing ring 17. The upper fixing ring 18 and the lower fixing ring 17 are welded and fixed to the plurality of barrier strips 19 in the middle, increasing structural strength. Furthermore, a gap is formed between two adjacent barrier strips 19 to allow water flow, while impurities larger than this gap are allowed to remain. The upper fixing ring 18 is fixedly sleeved outside the center, and the lower fixing ring 17 is fixedly fitted inside the secondary filter cup 6.

[0030] In this embodiment, a quick-connect fitting 20 is provided at the upper end of the central tube 16, and a quick-connect interface that mates with the quick-connect fitting 20 is provided at the bottom of the drain pipe 5. The central tube 16 and the drain pipe 5 are connected by an insertion method. This arrangement allows the secondary filter cup 6 to be quickly installed to the bottom of the drain pipe 5. Of course, the drain pipe 5 can also be connected to the central tube 16 by screwing. Regardless of the connection method, a sealing gasket needs to be provided on the connection surface to increase the sealing effect.

[0031] In this embodiment, a bottom shell 7 is provided at the bottom of the secondary filter cup 6; the bottom shell 7 is spirally connected to the main body of the secondary filter cup 6. This design provides a removable bottom shell 7, facilitating cleaning after excessive accumulation of impurities inside.

[0032] In this embodiment, a baffle plate 4 is provided around the primary filter bed 1. The baffle plate 4 is used to block the sludge and water. The upper surface of the primary filter plate 2 should be lower than the upper surface of the baffle plate 4 to prevent impurities left on the primary filter plate 2 from overflowing.

[0033] In this embodiment, a support column 11 is provided at the bottom of the primary filter bed 1. The entire structure is supported by the support column 11.

[0034] In this embodiment, a baffle plate 3 perpendicular to the rear end of the primary filter plate 2 is provided. The baffle plate 3 enhances the baffle plate effect at the bottom.

[0035] The filter layer 13 in this invention can be a sponge layer, a filter screen layer, and an activated carbon layer, which are arranged sequentially along the water flow direction.
