Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and more specifically, it relates to a solid-liquid separation device for wastewater treatment. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of residents' living standards, the discharge of domestic sewage is increasing year by year. Domestic sewage mainly comes from kitchen wastewater, washing wastewater, and toilet drainage generated in daily life, which contains a large amount of light solid impurities such as food scraps, hair, paper scraps, and fibrous materials. If this untreated sewage containing solids is directly discharged into the sewer pipes, it is very easy for sediment to accumulate at pipe bends, diameter changes, or low-flow-velocity areas. Long-term accumulation will lead to sewer blockage, affecting the normal operation of the drainage system, and even causing environmental sanitation problems such as sewage backflow and overflow.

[0003] To address the aforementioned issues, existing technologies typically incorporate solid-liquid separation devices at the upstream end of the sewer pipe to intercept solid impurities in wastewater, achieving preliminary solid-liquid separation. Common structures often employ a filter screen or basket directly embedded in a mounting bracket connected to the sewer pipe, secured by snap-fit ​​or threaded connections. However, these structures generally suffer from inconvenient assembly and disassembly: when the filter components accumulate significant impurities, they must be manually pulled out or rotated for removal, which is laborious and prone to damaging the snap-fit ​​structure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a solid-liquid separation device for wastewater treatment, which solves the problem that existing solid-liquid separation devices for wastewater treatment are inconvenient to assemble and disassemble, and when the filter components accumulate a lot of impurities, they need to be manually pulled out or rotated for disassembly, which is laborious and can easily damage the snap-fit ​​structure.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A solid-liquid separation device for wastewater treatment includes: a mounting base, a drain pipe, a solid-liquid separation component, a limiting block, and a disassembly / assembly component;

[0007] The mounting base has a hollow structure, and the lower end of the mounting base is connected to the upper end of the drain pipe;

[0008] The limiting blocks are arranged in a circumferential array along the solid-liquid separation component. The top of the mounting base has several limiting grooves corresponding to the limiting blocks. The inner end of the limiting groove penetrates the inner sidewall of the mounting base. The limiting blocks are engaged with the limiting grooves. The solid-liquid separation component is limited in the mounting base by the limiting blocks.

[0009] The disassembly and assembly components are provided in two sets, and the two sets of disassembly and assembly components are set on two oppositely distributed limit blocks. The disassembly and assembly components include disassembly and assembly grooves, wedge blocks, pull blocks, first springs and second springs.

[0010] The disassembly groove is formed on the upper surface of the corresponding limiting block, the outer end of the disassembly groove extends outward through the corresponding limiting block, the wedge block is horizontally slidably sleeved in the disassembly groove, and the inclined surface of the wedge block faces downward.

[0011] The inner wall of the disassembly groove opposite to the outer end is provided with a horizontal mounting hole. The inner and outer ends of the first spring are fixedly connected to the inner side wall of the mounting hole and the inner side wall of the wedge block, respectively. The first spring is horizontally distributed.

[0012] The pull block is fixedly connected to the upper surface of the wedge block and located inside the limiting block. The upper surface of the pull block is flush with the upper surface of the limiting block.

[0013] The limiting groove and the inner wall of the solid-liquid separation component are respectively provided with a matching positioning groove for the wedge block, and the outside of the wedge block can be slidably sleeved in the positioning groove.

[0014] Each of the limiting grooves has a limiting hole extending downwards on its inner bottom wall. A second spring is vertically installed in each limiting hole. The lower end of the second spring is fixedly connected to the inner bottom wall of the limiting hole, and the upper end of the second spring abuts against the bottom of the limiting block.

[0015] Furthermore, the solid-liquid separation assembly includes a filter cover, a filter frame, and an annular frame;

[0016] The bottom of the annular frame is fixedly connected to the top of the filter frame, and several water seepage holes are opened on the outer peripheral wall of the filter frame, and several filter holes are opened at the bottom of the filter frame.

[0017] The top of the annular frame is provided with an annular groove that fits the filter cover. The filter cover can be engaged with the annular groove. The filter cover is provided with several water-filtering strip holes.

[0018] Furthermore, the filter frame is a funnel-shaped frame structure with an opening at the top.

[0019] Furthermore, the limiting block has a rectangular structure, and the inner surface of the limiting block is an arc-shaped surface that matches the arc-shaped surface of the outer surface of the annular frame. The inner surface of the limiting block is fixedly connected to the outer surface of the annular frame.

[0020] Furthermore, a drain hole is provided on the inner wall of the limiting hole, and the drain hole is located at the bottom of the limiting hole. The inner end of the drain hole is connected to the hollow inner cavity of the mounting base.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This utility model achieves rapid installation, convenient disassembly, and automatic ejection of the solid-liquid separation component through the combined use of the limiting block and the disassembly assembly. Specifically, by setting a vertical second spring, during disassembly, the pull block is pulled to disengage the wedge block from the positioning groove, releasing the compressive potential energy and lifting the limiting block and the entire solid-liquid separation component upward, so that the solid-liquid separation component automatically moves upward and detaches from the mounting base without manual forced removal, significantly improving the convenience of cleaning and realizing automatic pop-up disassembly.

[0023] 2. Multiple limiting blocks in a circumferential array are used in conjunction with limiting grooves to achieve circumferential limiting. Combined with the lateral locking of wedge blocks and positioning grooves, this ensures that the solid-liquid separation component does not loosen or shift under the impact of water flow, thus improving installation reliability and stability.

[0024] 3. Suitable for scenarios involving lightweight solid impurities, especially lightweight but easily accumulated impurities such as hair, paper scraps, and food residue in domestic sewage. The design is reasonably matched with the spring force and the structure's own weight to ensure that the impurities can still be pushed out smoothly even when they are piled up.

[0025] 4. After installation, the filter cover, ring frame, limit block, and mounting base are flush with each other, making the whole structure aesthetically pleasing. It does not protrude from the ground or drain outlet, has a compact structure, and a flat appearance, avoiding the risk of tripping. It is suitable for residential scenarios such as kitchens and bathrooms. Attached Figure Description

[0036] Example 1:

[0037] As attached Figure 1 To be continued Figure 5 As shown:

[0038] This utility model provides a solid-liquid separation device for sewage treatment, including: a mounting base 1, a drain pipe 2, a solid-liquid separation component 3, a limiting block 5, and a disassembly and assembly component 4;

[0039] The mounting base 1 has a hollow structure, and the lower end of the mounting base 1 is connected to the upper end of the drain pipe 2.

[0040] Several limiting blocks 5 are arranged in a circumferential array along the solid-liquid separation component 3. Several limiting grooves 11 are opened on the top of the mounting base 1 corresponding to several limiting blocks 5. The inner end of the limiting groove 11 penetrates the inner sidewall of the mounting base 1. The limiting blocks 5 are engaged with the limiting grooves 11. The solid-liquid separation component 3 is limited in the mounting base 1 by the limiting blocks 5.

[0041] The disassembly and assembly component 4 is provided in two sets, and the two sets of disassembly and assembly components 4 are provided on any two relatively distributed limiting blocks 5. The disassembly and assembly component 4 includes a disassembly and assembly groove 41, a wedge block 42, a pull block 43, a first spring 44 and a second spring 45.

[0042] The disassembly groove 41 is formed on the upper surface of the corresponding limiting block 5, and the outer end of the disassembly groove 41 extends outward through the corresponding limiting block 5. The wedge block 42 is horizontally slidably sleeved in the disassembly groove 41, and the inclined surface of the wedge block 42 faces downward.

[0043] The mounting and disassembly groove 41 has a horizontally opened mounting hole 46 on the inner groove wall opposite to the outer end. The inner and outer ends of the first spring 44 are fixedly connected to the inner side wall of the mounting hole 46 and the inner side wall of the wedge block 42, respectively. The first spring 44 is horizontally distributed.

[0044] The pull block 43 is fixedly connected to the upper surface of the wedge block 42 and is located inside the limiting block 5. The upper surface of the pull block 43 is flush with the upper surface of the limiting block 5.

[0045] The limiting groove 11 and the solid-liquid separation component 3 have a corresponding positioning groove 12 on the inner wall of the wedge block 42, and the outside of the wedge block 42 can be slidably sleeved in the positioning groove 12.

[0046] Each of the limiting grooves 11 has a limiting hole 13 formed downward on its inner bottom wall. Each limiting hole 13 has a second spring 45 vertically arranged inside it. The lower end of the second spring 45 is fixedly connected to the inner bottom wall of the limiting hole 13, and the upper end of the second spring 45 abuts against the bottom of the limiting block 5.

[0047] In this embodiment, six limiting blocks 5 are provided. Two sets of disassembly and assembly components 4 are respectively set on two limiting blocks 5 that are distributed opposite each other at the left and right ends of the solid-liquid separation component 3. When the wedge block 42 is not subjected to external force, the lower end of the inclined surface of the wedge block 42 is located in the disassembly and assembly groove 41. When installing the solid-liquid separation component 3, the six limiting blocks 5 on the solid-liquid separation component 3 are aligned with the corresponding limiting grooves 11 on the mounting base 1, and then the solid-liquid separation component 3 is pressed down. At this time, the inclined surface of the wedge block 42 abuts against the upper groove opening of the limiting groove 11, and the wedge block 42 slides inward along the disassembly and assembly groove 41. The wedge block 42 moves until it is fully inside the limiting groove 11 and continues to move downward until it is aligned with the positioning groove 12. Under the action of the first spring 44, the wedge block 42 slides outward and the outside of the wedge block 42 slides into the positioning groove 12, and the limiting block 5 is engaged in the limiting groove 11, thus completing the installation of the solid-liquid separation component 3. Alternatively, the pull block 43 can be pulled to move the wedge block 42 inward to install the solid-liquid separation component 3. When the limiting block 5 is engaged in the limiting groove 11, the upper surface of the limiting block 5 is flush with the upper surface of the mounting base 1.

[0048] When disassembling the solid-liquid separation component 3, pulling the pull block 43 causes the wedge block 42 to disengage from the positioning groove 12, so that the second spring 45 is no longer blocked by the wedge block 42. Several second springs 45 are no longer compressed by the wedge block 42 and push upward against the limiting block 5, thereby pushing the solid-liquid separation component 3 to move upward out of the mounting base 1, making it easy to remove the solid-liquid separation component 3 from the mounting base 1, thereby cleaning solid impurities.

[0049] As a preferred embodiment, the solid-liquid separation component 3 includes a filter cover 31, a filter frame 32, and an annular frame 33;

[0050] The bottom of the annular frame 33 is fixedly connected to the top of the filter frame 32. The outer peripheral wall of the filter frame 32 is provided with a number of arrayed water seepage holes 35, and the bottom of the filter frame 32 is provided with a number of arrayed filter holes 36.

[0051] The top of the annular frame 33 has an annular groove 34 that fits the filter cover 31. The filter cover 31 can be engaged with the annular groove 34. The filter cover 31 has several water-filtering strip holes 37. When the filter cover 31 is engaged in the annular groove 34, the upper surface of the filter cover 31 is flush with the upper surface of the annular frame 33. Wastewater first passes through the strip holes of the filter cover 31 to intercept larger impurities (such as paper scraps and large food residues), and then flows into the funnel-shaped filter frame 32. It filters out small impurities (such as hair and debris) through the side wall seepage holes 35 and the bottom filter holes 36. Clean water flows into the drain pipe 2 through the mounting base 1, while solid impurities remain in the filter frame 32. The filter holes of different diameters are adapted to impurities of different sizes, avoiding the problem of easy clogging of a single filter layer. The annular groove 34 enables quick disassembly and assembly, making it convenient to clean the filter cover 31 separately or to deeply clean the impurities inside the filter frame 32.

[0052] In this embodiment, after installation, the upper surface of the filter cover 31, the upper surface of the annular frame 33, the upper surface of the mounting base 1, and the upper surface of the limiting block 5 are all flush.

[0053] As a preferred embodiment, the filter frame 32 is a funnel-shaped frame structure with an open top.

[0054] In this embodiment, the filter frame 32 is a funnel-shaped frame structure with an open top, which increases the contact area between the sewage and the filter frame 32, improves the drainage speed, and at the same time uses gravity to allow impurities to naturally settle to the bottom of the filter frame 32, making it easy to clean.

[0055] As a preferred embodiment, the limiting block 5 has a rectangular structure, the inner surface of the limiting block 5 is an arc-shaped surface, and it is adapted to the arc-shaped surface of the outer surface of the annular frame 33. The inner surface of the limiting block 5 is fixedly connected to the outer surface of the annular frame 33.

[0056] In this embodiment, the limiting block 5 is rectangular in shape. The rectangular structure ensures the precise fit between the limiting block 5 and the limiting groove 11, avoids offset during installation, and provides sufficient bearing area. The inner surface is arc-shaped and fits tightly with the outer wall of the annular frame 33. The arc-shaped fit design improves the connection stability and prevents loosening.

[0057] In this embodiment, the four limiting blocks 5 without the disassembly and assembly components 4 are hollowed out to reduce the weight of the limiting blocks 5.

[0058] As a preferred embodiment, a drain hole 14 is provided on the inner side wall of the limiting hole 13, and the drain hole 14 is located at the bottom of the limiting hole 13. The inner end of the drain hole 14 is connected to the hollow inner cavity of the mounting base 1.

[0059] In this embodiment, during use, the bottom of the limiting block 5 abuts against the upper end of the limiting hole 13 to seal the upper opening of the limiting hole 13. In order to prevent sewage from possibly seeping into the limiting hole 13 during the flow process, the drain hole 14 can guide the water accumulated in the limiting hole 13 into the inner cavity of the mounting base 1 and finally discharge it into the drain pipe 2, so that the water in the limiting hole 13 can flow into the drain pipe 2 through the drain hole 14.

[0060] In this embodiment, the mounting base 1 is made of rigid PVC, which is corrosion-resistant and impact-resistant, and suitable for the humid environment of the sewer. The filter cover 31, filter frame 32 and annular frame 33 are all made of stainless steel 304, which is corrosion-resistant and has high strength, and is suitable for frequent disassembly and cleaning. The limiting block 5, wedge block 42 and pull block 43 are made of engineering plastic ABS, which has both strength and toughness, and avoids damage when colliding with the mounting base 1. The first spring 44 and the second spring 45 are made of stainless steel springs, which are corrosion-resistant and have stable elasticity, and can be used for a long time in a humid environment without rusting or failure. In this embodiment, the maximum extension force of the second spring 45 is greater than the total weight of the solid-liquid separation component 3 (including filter cover 31, filter frame 32 and annular frame 33), the limiting block 5 and the attached impurities, ensuring that the component can be smoothly pushed out during disassembly.

[0061] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
