Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and in particular to a treatment device based on a drainage system of a building. Background Art

[0002] The drainage system of a building is a relatively important part of building construction. It is mainly used to discharge sewage from the building. During the drainage process, it is generally necessary to cooperate with the sewage treatment device to further treat the sewage. The treatment device of the drainage system of a building is a key component to ensure smooth drainage, water purification and environmental protection.

[0003] Among them, the grease separator is a more important treatment device in the drainage system of buildings. Its main function is to separate grease, water and some solid residues in oily wastewater to prevent grease from clogging the pipes. It is generally equipped with an oil-water separator, a solid-liquid separator and a sewage lift. First, the oil and water and solid residues are separated by the solid-liquid separator, and then the oil and water are separated by the oil-water separator. After that, the separated sewage is transported to the sewage lift, and the sewage lift discharges the sewage to the designated treatment point for further purification.

[0004] During use, the solid-liquid separator in the existing oil separator separates oil, water and solid residue through a sieve drum. Oil and water are usually viscous. When oil and water pass through the sieve holes of the sieve drum, some oil and water remain on the inner wall of the sieve holes of the sieve drum. After the residual oil and water solidify, it is easy to cause the sieve holes of the sieve drum to be blocked, affecting the normal solid-liquid separation work.

The mounting seat 52 is located at the bottom of the sieve drum 4, and a heating tube 53 is fixedly connected to the mounting seat 52. The heating tube 53 is an infrared halogen lamp tube. The position of the rotating shaft of the mounting bracket 5 is flush with the center of the arc of the sieve drum 4, and the length of the mounting bracket 5 is greater than the radius of the arc of the sieve drum 4, ensuring that the mounting bracket 5 is always located outside the arc of the sieve drum 4 during the rotation process.

[0042] Furthermore, the rotation of the conveying paddle 43 drives the driving gear A 63 to rotate, and the driving gear A 63 drives the driving gear B 64 to rotate. At this time, the driving gear B 64 drives the connecting rod 65 to rotate synchronously. During the rotation of the connecting rod 65, the slide plate 62 that is slidably connected to the guide rail 62 rotates together. At this time, the slide plate is limited by the guide rail 62, so that the slide plate slides along the guide rail 62. At this time, the force applied by the connecting rod 65 drives the guide rail 62 and the rack plate 61 to move back and forth along the limiting frame 6. The rack plate 61 drives the transmission gear 51 to rotate repeatedly. At this time, the transmission gear 51 drives the mounting frame 5 to swing back and forth.

[0044] The oil pan 7 is a kind of oil pan with a plurality of oil drain plugs, and the plurality of oil drain plugs are connected, and the plurality of oil drain plugs are connected, so that the plurality of oil drain plugs are connected, and the plurality of oil drain plugs are connected, so that the plurality of oil drain plugs are connected, and the plurality of oil drain plugs are connected.

[0045] Combined with attachment Figure 4 、 Figure 12 and Figure 13As shown, some fine sediments that pass through the screen of the screen drum 4 will be deposited at the bottom of the oil-water separator 1. In order to prevent the oily sewage discharged from the oil-water delivery pipe 22 from directly impacting the sediment at the bottom of the oil-water separator 1, the present application has made the following design: an inclined rod 10 is fixedly connected to the oil-water separator 1, and the inclined rod 10 is set lower on the left and higher on the right. The left end of the inclined rod 10 is located below the water delivery pipe 32. In order to facilitate better support and prevent the inclined rod 10 from bending and affecting the rotation of the slider 101, the inclined rod 10 is supported by a support rod in the sewage lift 3. Multiple groups of sliders 101 are rotatably connected to the inclined rod 10. The material of the sliders 101 is wear-resistant plastic. There are two sliders in each group. A plurality of baffles 102 are installed in a circular array between each group of sliders 101. The material of the baffles 102 is lightweight plastic. The slider 101 is sealed and slidably connected with a movable rod 10 3. The two movable rods 103 on the same group of sliders 101 have an arc-shaped side that is close to each other and cooperates with the rods at both ends of the baffle 102. The baffle 102 provides a guide for the movement of the movable rod 103. A scraper 104 is fixedly connected between the two movable rods 103 to facilitate scraping grease and solid residues on the baffle 102. The scraper 104 is in the shape of a cone, diamond or prism for easy scraping. The scraper 104 contacts the surface of the baffle 102.

The magnetic blocks 107 are located on the movement trajectory of the magnetic cake 105, and the magnetic properties of the magnetic blocks 107 are opposite to those of the magnetic cake 105.

[0046] Furthermore, after the oily sewage is discharged from the oil-water conveying pipe 22, it falls on the inclined rod 10 and the baffle 102, and the baffle 102 and the slider 101 are driven to rotate under the impact of the oily sewage, so as to buffer the oily sewage and prevent the oily sewage from directly impacting the sediment at the bottom of the oil-water separator 1, thereby dispersing the sediment and prolonging the overall sedimentation time. At the same time, the slider 101 drives the magnetic cake 105 and the spring 106 to rotate synchronously. As the oily sewage impacts the baffle 102, some debris in the oily sewage adheres to the baffle 102. When the magnetic cake 105 and the spring 106 are driven to rotate synchronously, the oily sewage is displaced and the sediment is dispersed. When the cake 105 rotates to the position of the magnetic block 107, the magnetic cake 105 will move toward the position of the magnetic block 107 under the action of the magnetic force, and then the magnetic cake 105 drives the movable rod 103 and the scraper 104 to move synchronously. As the scraper 104 moves, the scraper 104 cleans the debris on the baffle 102, which is beneficial to the rotation of the baffle 102. When the magnetic cake 105 rotates away from the position of the magnetic block 107, the movable rod 103, the scraper 104 and the magnetic cake 105 are reset under the elastic force of the spring 106, and are ready for the next scraping.

[0047] Working principle:

[0048] The oil-water separator 1, the solid-liquid separator 2 and the sewage lifter 3 are assembled, and containers for collecting grease and solid residues are placed below the oil discharge pipe 12 and the discharge pipe 42 respectively. The feed pipe 21 is connected to the external oil and sewage pipe, and the drain pipe 34 is connected to the external sewage pipe. When discharging oily sewage, the oily sewage enters the screen drum 4 through the feed pipe 21, and the grease and water in the oily sewage are discharged through the sieve holes of the screen drum 4 and fall on the inner bottom of the solid-liquid separator 2. At this time, the motor 44 is started to drive the conveying paddle 43 to rotate. The conveying paddle 43 is a spiral structure, which conveys the solid residue remaining in the screen drum 4. When the solid residue is transported to the discharge pipe 42, the solid residue is discharged through the discharge pipe 42 and falls into the container below the discharge pipe 42, while the oil and water fall on the inner bottom of the solid-liquid separator 2 and enter the oil-water separator 1 through the oil-water conveying pipe 22 to perform oil-water separation.

[0049] When the oily sewage is discharged from the oil-water conveying pipe 22, it falls on the inclined rod 10 and the baffle 102, and the baffle 102 and the slider 101 are driven to rotate under the impact of the oily sewage, so as to buffer the oily sewage and prevent the oily sewage from directly impacting the sediment at the bottom of the oil-water separator 1, thereby dispersing the sediment and prolonging the overall sedimentation time. At the same time, the slider 101 drives the magnetic cake 105 and the spring 106 to rotate synchronously. As the oily sewage impacts the baffle 102, some debris in the oily sewage adheres to the baffle 102. When the magnetic cake 1 05 rotates to the position of the magnetic block 107, the magnetic cake 105 will move toward the position of the magnetic block 107 under the action of the magnetic force, and then the magnetic cake 105 drives the movable rod 103 and the scraper 104 to move synchronously. As the scraper 104 moves, the scraper 104 cleans the debris on the baffle 102, which is conducive to the rotation of the baffle 102. When the magnetic cake 105 rotates away from the position of the magnetic block 107, the movable rod 103, the scraper 104 and the magnetic cake 105 are reset under the elastic force of the spring 106, and are ready for the next scraping;

[0050] During the solid-liquid separation process, the conveying paddle 43 rotates to drive the driving gear A 63 to rotate, and the driving gear A 63 drives the driving gear B 64 to rotate, and the driving gear B 64 drives the connecting rod 65 to rotate synchronously, and the connecting rod 65 rotates and rotates together with the slide plate slidably connected to the guide rail 62. At this time, the slide plate is limited by the guide rail 62, so that the slide plate slides along the guide rail 62. At this time, the guide rail 62 and the rack plate 61 are driven by the connecting rod 65 to move back and forth along the limiting frame 6. During the back and forth movement, the rack plate 61 drives the transmission gear 51 to rotate back and forth repeatedly. At this time, the transmission gear 51 drives the mounting frame 5 to swing back and forth, and the heating tube 53 is turned on. During the back and forth swing of the mounting frame 5, the surface of the screen drum 4 is evenly heated through the heating tube 53 in the mounting seat 52, so that the grease in the screen of the screen drum 4 is heated, so that the grease is always in a liquid state, avoiding the problem of grease solidification and clogging the screen holes of the screen drum 4. At the same time, the convex surface is used According to the design of 73, when the heating tube 53 is heated, the light is concentrated on the screen drum 4 to increase the heating effect of the screen drum 4. At the same time, the heating tube 53 is covered by the transparent oil pan 7 to prevent oily water from falling on the heating tube 53. At the same time, the mounting frame 5 rotates to drive the mounting seat 52 to rotate together, and the ring gear 9 cooperates with the rotating gear 81 to drive the reciprocating screw 8 to rotate. The reciprocating screw 8 drives the scraper 82 to move back and forth along the oil pan 7. At this time, the oily water in the oil pan 7 is squeezed out by the scraper 82, so that the oily water in the oil pan 7 is discharged faster through the oil guide pipe 72. During the movement, the scraper 82 scrapes off the residual grease attached to the inner wall of the oil pan 7 to prevent the residual grease from adhering to the oil pan 7 and affecting the heating effect of the heating tube 53.

[0051] After the oily wastewater enters the oil-water separator 1, the ultrasonic generator 13 is started to accelerate the separation of oil and water through ultrasonic microbubble oil-water separation technology. At this time, the mud and sand in the oily wastewater will be deposited at the bottom of the oil-water separator 1 and discharged through the sewage pipe 11. The grease will float on the surface of the sewage and be discharged through the oil drain pipe 12 into the container for collecting grease. The sewage is located in the middle position of the oil-water separator 1. After the oily wastewater is separated, the pump body A 31 is started to transport the sewage in the oil-water separator 1 into the sewage lift 3 through the water pipe 32.
