[0002] Domestic sewage is wastewater discharged from daily life, primarily from residential and public buildings, such as residences, government offices, schools, hospitals, shops, public places, and industrial restrooms. Kitchen and bathroom wastewater is the most common source of wastewater in residential buildings. Kitchen wastewater contains numerous and diverse impurities, many of which are difficult to remove through simple filtration. This places a significant burden on subsequent oxidation tanks, impacting operational efficiency. Therefore, we propose a grease separation device for domestic sewage.

[0003] For example, Chinese utility model patent publication number CN209890426U discloses a catering oil separator device comprising a solid-liquid separation box, an oil-water separation box, and a sewage discharge box connected in sequence. The solid-liquid separation box is equipped with a debris removal mechanism, the oil-water separation box is equipped with a heating mechanism and a stirring mechanism in the upper portion, and the upper portion of the oil-water separation box is equipped with multiple downwardly inclined oil drain pipes with switches. However, this type of device has some drawbacks. The connecting pipes are difficult to disassemble and assemble, and the sealing performance is poor, which reduces its practicality. Therefore, a connection structure for an oil separator lifting device is proposed to address the above-mentioned issues. Utility Model Content

[0024] See also Figure 1-4, an embodiment of the present utility model is: a connection structure for oil separation and lifting equipment, comprising a solid-liquid separation box 1, an oil-water separation box 2 and a sewage discharge box 3 connected in sequence, a first connecting pipe 4 is fixedly connected to the right side of the solid-liquid separation box 1, a second connecting pipe 5 is provided on the top of the oil-water separation box 2, and a connecting mechanism 6 is provided between the second connecting pipe 5 and the first connecting pipe 4; the connecting mechanism 6 comprises: a fixed cylinder 61, a retaining ring 62, a fixing ring 63, a sealing groove 64, a sealing gasket 65, and a protrusion 66, the fixing cylinder 61 is movably sleeved on the outer wall of the second connecting pipe 5, the retaining ring 62 is fixedly sleeved on the outer wall of the second connecting pipe 5, and the right side of the retaining ring 62 is in contact with the inner wall of the fixing cylinder 61, the fixing ring 63 is fixedly sleeved on the outer wall of the first connecting pipe 4, the inner wall of the fixing cylinder 61 is provided with an internal thread, and the outer wall of the fixing ring 63 is provided with a thread that is connected to the fixing cylinder 61 The outer thread of the cylinder 61 is matched with the outer thread of the cylinder 61, and the fixed cylinder 61 is threadedly connected to the fixing ring 63. The sealing groove 64 is opened on the right side of the first connecting tube 4, the sealing gasket 65 is fixedly connected to the inner wall of the sealing groove 64, and the protrusion 66 is fixedly connected to the left side of the second connecting tube 5. The sealing gasket 65 is arranged in an isosceles trapezoidal shape and is made of rubber material. The protrusion 66 is slidably connected to the inner wall of the sealing groove 64, and the left side of the protrusion 66 abuts against the right side of the sealing gasket 65. The retaining ring 62 is used to block the fixed cylinder 61, and the first connecting tube 4 and the second connecting tube 5 are fixed by threading the fixing cylinder 61 and the fixing ring 63. The disassembly and assembly are convenient and the practicality is improved. The protrusion 66 is used to squeeze the sealing gasket 65, so that the sealing gasket 65 is deformed and fills the sealing groove 64, thereby sealing the connection between the first connecting tube 4 and the second connecting tube 5 and improving the sealing performance.

[0025] Working principle: by aligning the first connecting tube 4 and the second connecting tube 5, using the retaining ring 62 to block the fixing tube 61, rotating the fixing tube 61 to make it slide along the retaining ring 62 and the outer wall of the second connecting tube 5, and at the same time making the fixing tube 61 threadedly connected to the fixing ring 63, thereby connecting and fixing the first connecting tube 4 and the second connecting tube 5, and convenient disassembly and assembly. At the same time, it can be seen from the figure that the sealing gasket 65 is in the initial state at this time. When the fixing tube 61 continues to be rotated, the fixing tube 61 drives the second connecting tube 5 to move in the direction of the first connecting tube 4, and the second connecting tube 5 drives the protrusion 66 to slide along the inner wall of the sealing groove 64, and uses the protrusion 66 to squeeze the sealing gasket 65, causing the sealing gasket 65 to deform and fill the sealing groove 64, thereby sealing the connection between the first connecting tube 4 and the second connecting tube 5, improving the sealing performance, and making the first connecting tube 4 and the second connecting tube 5 more firmly connected.
