Description

Technical Field

[0001] This utility model belongs to the field of wastewater filtration technology, and in particular relates to a kitchen wastewater filtration device. Background Technology

[0002] Wastewater generally refers to wastewater that is polluted to some extent and originates from domestic and industrial activities. Wastewater generation is unavoidable in daily life. For example, kitchen wastewater is rich in cooking oil and food scraps. If this wastewater is discharged directly without treatment, it can easily cause pipe blockages because food scraps and oil adhere to the inner walls of the pipes. Furthermore, the food scraps trapped inside the pipes will gradually rot, emitting unpleasant odors, thus negatively impacting the quality of life for residents.

[0003] Most commercially available kitchen wastewater filtration equipment relies on filter screens to separate solids from liquids. Specifically, as wastewater passes through the filter, the liquid portion flows into the drain, while the solid residue is trapped and requires manual cleaning and disposal in a trash can. However, this method of filtering wastewater solely through a filter screen only achieves a basic solid-liquid separation. Grease and other grease components in kitchen wastewater will flow directly into the drain along with the liquid. Over time, this can easily lead to blockages in the drain due to grease buildup. Utility Model Content

[0004] The purpose of this utility model is to provide a kitchen wastewater filtration device with a simple structure. After the wastewater is allowed to settle and separate into layers, it is discharged into the sewer, thus preventing the sewer from becoming clogged.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0015] Example 1 The kitchen wastewater filtration device described in this embodiment, such as Figures 1 to 3As shown, it includes a horizontally settling tank 1, which is installed at the bottom of the kitchen sink. Kitchen water flows into the settling tank 1 through a pipe. After the oily sewage settles in the settling tank 1, it separates into three layers: the upper layer of oily sewage floats on top of the sewage, the middle layer is sewage, and the lower layer is sediment. By removing the upper layer of oily sewage in advance, the middle layer of sewage is discharged into the sewer, and the lower layer of sediment is collected and cleaned, thus preventing the oily sewage and sediment from being directly discharged into the sewer and causing blockage. A drain pipe is horizontally installed in the middle of the left side wall of settling tank 1. A valve is installed on the drain pipe. A through hole is opened in the middle of the left side wall of settling tank 1, and the drain pipe is inserted into the through hole. The middle layer sewage after settling is discharged into the sewer through the drain pipe. The valve is used to control the opening and closing of the drain pipe to ensure the settling time of the sewage in settling tank 1. The top of the settling tank 1 is detachably equipped with a cover plate 3. The cover plate 3 is horizontally set on the top of the settling tank 1. The detachable structure makes it easy to clean the sediment and dirt at the bottom of the settling tank 1. A connecting pipe 9 is vertically fixed to the right side of the settling tank 1. The connecting pipe 9 is vertically fixed to the right side wall of the settling tank 1. A water inlet pipe 10 is horizontally installed on the right side wall of the settling tank 1 to connect the settling tank 1 and the connecting pipe 9. A through hole with internal and external communication is horizontally opened on the right side wall of the settling tank 1. The water inlet pipe 10 is horizontally installed in the through hole. The right end of the water inlet pipe 10 is connected to the bottom of the connecting pipe 9. The left end of the water inlet pipe 10 is inserted into the settling tank 1. The connecting pipe 9 is connected to the settling tank 1 through the water inlet pipe 10. Kitchen water is discharged into the settling tank 1 through the connecting pipe 9. A liquid inlet pipe 6 is vertically fixed at the top of the connecting pipe 9 and communicates with the connecting pipe 9. The liquid inlet pipe 6 is installed at the upper end of the connecting pipe 9 and is connected to the connecting pipe 9. The liquid is used to flow into the connecting pipe 9 through the liquid inlet pipe 6. A filter screen 7 is detachably installed at the bottom outlet of the liquid inlet pipe 6. The filter screen 7 is installed at the bottom outlet of the liquid inlet pipe 6. Large particles of impurities in the kitchen water, such as meat scraps and vegetable leaves, are separated by the filter screen 7 to prevent them from entering the sewer and causing blockage. The settling tank 1 is vertically equipped with guide plates 5 to slow down the flow rate of sewage. There are multiple guide plates 5, which are installed in the settling tank 1. The multiple guide plates 5 block the water flowing into the settling tank 1 through the connecting pipe 9, slow down its flow rate, and prevent the subsequent sewage from flowing into the settling tank 1 and stirring up the settled sewage, which is conducive to the extraction of oil. An oil extraction pipe 16 is horizontally installed inside the settling tank 1, positioned above the liquid surface to remove oil floating on top of the wastewater. Several oil inlets 18 are installed at the bottom of the oil extraction pipe 16 to extract oil from the wastewater surface. Floats 17 are fixed at both ends of the oil extraction pipe 16, moving up and down with the wastewater surface to ensure the oil inlets 18 contact the oil, preventing situations where the inlets are fixed but the liquid level is too low to extract oil. An oil pump 11 is installed on the side wall of the settling tank 1, connected to the oil extraction pipe 16 via a flexible hose 12. The oil pump 11 is mounted on the outer side wall of the settling tank 1, and the flexible hose 12... One end is connected to the oil extraction pipe 16, and the other end is connected to the oil extraction pump 11. The oil extraction pump 11 draws away the oil from the surface of the sewage through the oil extraction pipe 16 and the hose 12. This section constitutes an oil extraction assembly for sucking away oil from the surface of sewage. When the oil extraction assembly is in use, the float 17 floats on the surface of the sewage, and the oil extraction pipe 16 is horizontally positioned above the oil under the action of the float 17. The oil inlet 18 is inserted into the oil, and the oil extraction pump 11 draws away the oil floating on the surface of the sewage, preventing the oil from being directly discharged into the sewer and causing sewer blockage. Of course, the oil extraction assembly can also have an oil collection box installed at the bottom of the oil extraction pump 11. The oil extracted by the oil extraction pump 11 is collected in the oil collection box for centralized treatment.

[0016] In this embodiment, the settling tank 1 is installed at the bottom of the kitchen sink. Kitchen water is collected in the settling tank 1 after passing through the inlet pipe 6 and the connecting pipe 9. The wastewater undergoes a preliminary process through the filter screen 7, filtering out large particles of impurities. After settling in the settling tank 1, the oily wastewater separates into three layers: the upper layer of oil floats on top of the wastewater, the middle layer is wastewater, and the lower layer is sediment. The upper layer of oil is removed in advance by the oil extraction component. The middle layer of wastewater is discharged into the sewer through the drain pipe on the left side of the settling tank 1. The lower layer of sediment settles in the settling tank 1 and is cleaned by opening the cover plate 3, thereby preventing the oil and sediment from being directly discharged into the sewer and causing blockage. During the wastewater sedimentation process, the newly discharged wastewater slows down its flow rate after passing through the guide plate 5 to prevent it from affecting the settling of the wastewater in the settling tank 1.

[0017] Example 2 This embodiment further illustrates the technology, such as Figure 1 As shown, two side plates 4 are vertically fixed on the front and rear inner side walls of the settling tank 1, and floats 17 are respectively set between the corresponding side plates 4. The floats 17 and the side plates 4 slide up and down. There are four side plates 4, two in a group, which are installed on the front inner side wall and the rear inner side wall of the settling tank 1, respectively. The two side plates 4 form a chute to restrict the movement of the floats 17. The floats 17 can only slide up and down along the length of the chute to prevent the floats 17 from floating around on the liquid surface and to ensure the cleaning effect of the oil stains.

[0018] Example 3 This embodiment further illustrates the technology, such as Figure 2 As shown, a sliding groove is provided on the inner side wall of the settling tank 1, and a slider 13 is provided in the sliding groove to slide up and down with it. The sliding groove is vertically opened on the inner side wall of the settling tank 1, and the slider 13 slides up and down along the length of the sliding groove. The end of the guide plate 5 is fixed on the slider 13. The guide plate 5 is inserted into the groove together with the slider 13, so as to realize the quick assembly and disassembly of the guide plate 5, which is conducive to the subsequent cleaning of the guide plate 5 and the settling tank 1. The guide plate 5 is inclined and set on the left side of the inlet pipe 10. The guide plate 5 is used to block the sewage flowing into the settling tank 1 from the connecting pipe 9, slow down its flow rate, and prevent the sewage flowing in from stirring up the water after it has settled and separated.

[0019] The end of the guide plate 5 is fixed with a sub-plate 15. The sub-plate 15 has an overall arc-shaped structure. The sub-plate 15 is fixed to the end of the guide plate 5. The arc-shaped sub-plate 15 further slows down the flow rate of sewage, which is conducive to the settling and stratification of sewage.

[0020] Example 4 This embodiment further illustrates the technology, such as Figure 1 As shown, the inner bottom of the liquid inlet pipe 6 has a funnel structure, and a retaining ring 8 is fitted on the upper end of the filter screen 7. The retaining ring 8 is stuck on the inner side wall of the liquid inlet pipe 6. The inner bottom of the liquid inlet pipe 6 has an inclined structure, and the diameter of the retaining ring 8 is larger than the width of the bottom opening of the liquid inlet pipe 6. The filter screen 7 is hung at the bottom opening of the liquid inlet pipe 6 through the retaining ring 8, so as to realize the detachable connection of the filter screen 7, which is conducive to cleaning the impurities inside the filter screen 7.

[0021] Example 5 This embodiment further illustrates the technology, such as Figure 1 As shown, a connector 2 is fixed to the top of the cover plate 3. The connector 2 has an "L" shape and is installed on the top of the settling tank 1 with screws. There are two connectors 2, which are fixed to the left and right ends of the cover plate 3 respectively. The cover plate 3 can be detachably installed at the top opening of the settling tank 1 through the connector 2, which is conducive to the subsequent cleaning of the guide plate 5 and the settling tank 1.
