Description

Technical Field

[0001] This utility model relates to the field of building drainage, specifically a device for intercepting and automatically cleaning grease from building risers. Background Technology

[0002] The drainage system of industrial buildings is an important component to ensure the normal use of the buildings and environmental hygiene. Its design needs to take into account factors such as building function, sewage treatment standards, climate conditions, and water consumption.

[0003] In existing drainage devices, wastewater containing kitchen grease in the drain pipe is discharged. As the grease flows downward, it tends to adhere to the inner wall of the drain pipe. If it is not intercepted and cleaned, it can easily form blockages when it accumulates too much, causing poor water flow. Furthermore, the accumulation of grease can corrode the inner wall of the pipe. Especially when in long-term contact with water and grease, it can also produce an unpleasant odor, seriously affecting public health.

[0004] Therefore, a device for grease trapping and automatic cleaning of building risers is proposed to address the above problems. Utility Model Content

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. The structural design of the filter screen in this utility model can ensure the passage of large pieces of garbage in the water. With the help of scrapers, brushes and crushing blades, the scrapers can continuously scrape the oil sludge on the wall surface when rotating, assisting the oil sludge to descend and accumulate on the annular filter screen.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4As shown, a building riser grease trapping and automatic cleaning device includes a housing 1. A water inlet 2 is fixedly connected to the top of the housing 1, and a water outlet 3 is fixedly connected to the bottom of the housing 1. The inner diameter of the housing 1 is larger than the inner diameter of the pipe and has a smooth transition section. The housing 1 is a metal structure, which can cool the water through indoor temperature, facilitating oil film solidification. A rotating rod 5 is rotatably connected to the inside of the housing 1 via a fixed plate 4. An annular filter screen 7 is installed on the side of the inside of the housing 1 near the water outlet 3. A collection cover 9 is fixedly connected to the outside of the housing 1. A spiral conveying rod 10 extends from the top of the collection cover 9 into the inside of the housing 1 and is rotatably connected to it. A scraping assembly is installed outside the rotating rod 5. A linkage assembly is installed inside the housing 1. The scraping assembly includes a scraper 6. 6 is symmetrically fixed to both sides of the rotating rod 5 by fixed rods. A brush plate 8 is fixedly connected to the end of the rotating rod 5 near the filter screen 7. Multiple crushing blades 11 are fixedly connected to the outside of the rotating rod 5 and between the two fixed rods. The linkage component includes a motor 12 and a linkage unit. The motor 12 is fixedly connected to the outside of the collection cover 9. The output end of the motor 12 extends into the inside of the collection cover 9 and is fixedly connected to the spiral conveying rod 10. The rotating rod 5 can be rotated by the linkage unit. The linkage unit includes a first bevel gear 14. The first bevel gear 14 is fixedly connected to the end of the spiral conveying rod 10 near the rotating rod 5. A second bevel gear 15 is fixedly connected to the outside of the rotating rod 5. The first bevel gear 14 and the second bevel gear 15 are meshed together.

[0026] During operation, connect the inlet 2 to the upper outlet pipe, and then connect the lower drain pipe to the outlet 3. Water can then be drained into the device through the outlet pipe. The filter screen 7's structural design ensures the passage of large debris in the water. Start the motor 12; its output drives the screw conveyor 10 to rotate. During rotation, the screw conveyor 10 drives the first bevel gear 14, which in turn drives the second bevel gear 15 and the rotating rod 5. The rotating rod 5 then drives the external scraper 6, brush 8, and crusher 11 to rotate. The scraper 6 continuously scrapes the sludge on the wall surface, assisting it to descend and accumulate on the annular filter screen 7. The brush 8 continuously cleans the filter screen 7, carrying the sludge there, and the mesh structure traps residual oil on the wall surface. The sludge is finally located at the screw conveyor 10, achieving oil sludge separation and discharge. During the rotation process, the screw conveyor 10 can transport the accumulated oil sludge to the collection hood 9 on one side. As the screw conveyor 10 rotates continuously, it can continuously push the oil sludge inside the collection hood 9. Therefore, the oil sludge transported to the collection hood 9 will not flow back into the shell 1, ensuring the collection effect of oil sludge and facilitating centralized processing by staff. Moreover, the shell 1, made of metal structure, can cool the water through the indoor temperature, thereby increasing the viscosity of the grease or even solidifying the grease. The metal shell expands gradually, slowing down the flow rate, and is only useful for small flow rates. In the case of large flow rates, there is no need to remove oil. The crusher 11 has a certain area and can be impacted and rotated under large water flow to prevent it from being stuck by oil sludge. At the same time, it can cut some fibers to prevent overall entanglement.

[0027] In some embodiments, multiple sets of bristles are provided on the outer side of the brush plate 8 near the filter screen 7, the diameter of the second bevel gear 15 is smaller than the diameter of the first bevel gear 14, a sealing cover 13 is detachably connected to the bottom of the collection cover 9, a mounting plate 16 is fixedly connected to the outer side of the sealing cover 13, and a bolt 17 is threadedly connected to the upper inner side of the mounting plate 16, one end of the bolt 17 extends into the interior of the collection cover 9 and is threadedly connected thereto.

[0028] With the above technical solution, when the drainage is completed, the sealing cover 13 can be disassembled by unscrewing the bolt 17, and the oil sludge inside the collection cover 9 can be centrally treated.

[0029] In some embodiments, the outside of the collection cover 9 is provided with heat dissipation holes on one side of the motor 12, and the motor 12 is electrically connected to an external controller.

[0030] The above technical solution allows for easy heat dissipation of the running motor 12 through the heat dissipation holes, preventing the motor 12 from overheating and causing damage.

[0031] Example 2

[0032] Please see Figure 1 As shown in the comparison embodiment one, as another implementation of this utility model, two viewing windows 18 are respectively installed on one side of the outer shell 1, and the two viewing windows 18 are respectively installed above and below the filter screen 7. The two viewing windows 18 facilitate the staff to observe the drainage situation inside the shell 1 in real time, and prevent malfunctions.

[0033] During operation, connect the inlet 2 to the upper outlet pipe, and then connect the lower drain pipe to the outlet 3. Water can then be drained into the device through the outlet pipe. The filter screen 7's structural design ensures the passage of large debris in the water. Start the motor 12; its output drives the screw conveyor 10 to rotate. During rotation, the screw conveyor 10 drives the first bevel gear 14, which in turn drives the second bevel gear 15 and the rotating rod 5. The rotating rod 5 then drives the external scraper 6, brush 8, and crusher 11 to rotate. The scraper 6 continuously scrapes the sludge on the wall surface, assisting it to descend and accumulate on the annular filter screen 7. The brush 8 continuously cleans the filter screen 7, carrying the sludge there. The mesh structure traps residual sludge on the wall surface, ultimately reaching the screw conveyor 10 for separation and discharge. During rotation, the screw conveyor 10 transports the accumulated sludge to the collection hood 9 on one side. Due to the screw conveyor's... The conveying rod 10 rotates continuously, continuously pushing the sludge inside the collection hood 9. Therefore, the sludge transported to the collection hood 9 will not flow back into the housing 1, ensuring the collection effect of the sludge and facilitating centralized processing by staff. The housing 1, made of metal structure, can cool the water through the indoor temperature, thereby increasing the viscosity of the grease or even solidifying it. The metal outer shell expands gently, slowing down the flow rate. This is only useful for small flow rates; in large flow rates, there is no need for degreasing. The crushing blade 11 has a certain area and can be impacted and rotated under high water flow to prevent it from being stuck by the sludge. It can also cut some fibers to prevent them from becoming entangled. When drainage is complete, the sealing cover 13 can be removed by unscrewing the bolts 17, allowing for centralized processing of the sludge inside the collection hood 9. The heat dissipation holes facilitate the cooling of the running motor 12, preventing overheating and damage. The two viewing windows 18 allow staff to observe the drainage situation inside the housing 1 in real time, preventing malfunctions.
