Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically a kitchen wastewater oil separation mechanism. Background Technology
[0002] Kitchen wastewater often contains a large amount of grease, especially in the catering industry. The grease primarily originates from cooking oil, food scraps, and grease generated during processing. This grease exists as floating oil or emulsified oil, and if not treated promptly, it can lead to water pollution, sewer blockage, and increased difficulty in wastewater treatment. Therefore, efficient separation of floating oil from kitchen wastewater has become a key issue. Recent research has focused on improving separation efficiency and reducing environmental impact. In the future, kitchen wastewater floating oil separation technology will develop towards high efficiency, low energy consumption, environmental protection, and intelligentization, promoting more economical and sustainable solutions.
[0003] However, in actual use, many existing solutions employ traditional oil-water separation methods that rely on buoyancy to remove grease, often depending on the density difference between oil and water. Since the grease floats on the water surface, complete separation may take a considerable amount of time, especially when there is little grease or strong water flow, resulting in poor separation performance.
[0004] Therefore, this utility model provides a kitchen wastewater oil separation mechanism. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve the problem that traditional oil-water separation methods, which rely on the principle of buoyancy to remove grease, often depend on the density difference between oil and water for separation and are therefore inefficient, this utility model proposes a kitchen wastewater oil separation mechanism.

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1:
[0025] like Figures 1 to 6 As shown, the kitchen wastewater oil separation mechanism of this utility model includes a separation box 1. A motor 2 is fixedly connected to the middle of the left side of the separation box 1, supporting and fixing the motor 2. A transmission rod 21 is fixedly connected to the output end of the motor 2, supporting and fixing the transmission rod 21. The motor 2 drives the transmission rod 21 to rotate. Evenly distributed limiting components are provided on the outer side of the transmission rod 21, and connecting components are provided on the inner side of the limiting components. A loose rod 33 is provided on the outer side of the connecting components. The loose rod 33 is fixed by the cooperation of the limiting components and the connecting components, thereby allowing the transmission rod 21 to pass through. The rotation simultaneously drives the limiting component, the connecting component, and the bristle 33 to rotate, thereby adsorbing the oil stains stored in the separation box 1. A guide plate 4 is fixedly connected to the middle of the inner side of the separation box 1. The guide plate 4 is fixed by the separation box 1. The front end of the guide plate 4 has a uniformly distributed extrusion groove 41. The extrusion groove 41 is slidably connected to the bristle 33. The bristle 33 slides in the extrusion groove 41, thereby extruding the grease attached to the soft bristles on the outside of the bristle 33 through the extrusion groove 41. The bristle 33 adopts a flexible rod design in the middle, so that the bristle 33 can be bent. At the same time, the diameter of the extrusion groove 41 is similar to the diameter of the bristle 33.
[0026] The limiting assembly includes a fixed sleeve 22. Evenly distributed fixed sleeves 22 are fixedly connected to the outer side of the transmission rod 21, securing the fixed sleeves 22 via the transmission rod 21. Evenly distributed limiting balls 23 are slidably connected to the inner side of the middle end of the fixed sleeve 22, limiting the limiting balls 23 via the fixed sleeve 22. Simultaneously, the two ends of the through hole where the limiting balls 23 are located are designed with constricted ends, further limiting the limiting balls 23 so that they can only move within the through hole and will not fall out. A spring 24 is fixedly connected to the outer side of the bottom end of the fixed sleeve 22, securing the bottom end of the spring 24 via the fixed sleeve 22. A sliding sleeve 25 is slidably connected to the outer side of the fixed sleeve 22, allowing for... The fixed sleeve 22 limits the sliding sleeve 25, allowing the sliding sleeve 25 to slide outside the fixed sleeve 22. A locking ring 26 is fixedly connected to the inner side of the middle end of the sliding sleeve 25. The locking ring 26 is fixed by the sliding sleeve 25, and at the same time, the locking ring 26 is driven to rise and fall by the sliding sleeve 25. The bottom end of the locking ring 26 is fixedly connected to the spring 24. The spring 24 and the fixed sleeve 22 are used as stress points to push the locking ring 26 upward. The locking ring 26 engages with the limiting ball 23. The locking ring 26 limits the movement of the limiting ball 23. When the locking ring 26 engages with the limiting ball 23, the limiting ball 23 cannot move within the through hole.
[0027] The connecting assembly includes a locking post 3, which is slidably connected to the inner side of a fixed sleeve 22. The fixed sleeve 22 limits the locking post 3. A locking groove 31 is provided on the outer side of the middle end of the locking post 3. A threaded sleeve 32 is fixedly connected to the outer side of the top end of the locking groove 31. The threaded sleeve 32 is fixed by the locking groove 31. The threaded sleeve 32 is threadedly connected to a sliding sleeve 25. The external thread on the outer side of the threaded sleeve 32 and the internal thread on the inner side of the top end of the sliding sleeve 25 cooperate with each other, causing the sliding sleeve 25 to move up and down outside the fixed sleeve 22. The locking groove 31 is engaged with a limiting ball 23. The locking groove 31 and the limiting ball 23 engage with each other, thereby fixing the locking post 3.
[0028] A fixed frame 5 is fixedly connected to the middle of the rear side of the separation box 1. The fixed frame 5 is fixed by the separation box 1. A collection box 51 is slidably connected to the inner side of the bottom of the fixed frame 5. The collection box 51 is limited by the fixed frame 5. A front and rear opposite fixed bracket 52 is fixedly connected to the top of the outer side of the collection box 51. The collection box 51 fixes the fixed bracket 52 on both sides. The inner side of the fixed bracket 52 is threaded with left and right opposite bolts 53. The bolts 53 are threaded to the fixed frame 5. The fixed frame 5 and the collection box 51 are fixedly connected by the bolts 53. The collection box 51 can be disassembled to clean the grease stored in the collection box 51.
[0029] A water outlet pipe 12 is fixedly connected to the bottom right side of the separation tank 1, and a water inlet pipe 11 is fixedly connected to the top right side of the separation tank 1. Wastewater is transported into the separation tank 1 through the water inlet pipe 11 and discharged through the water outlet pipe 12.
[0030] A superhydrophobic layer is provided on the outer side of the hair shaft 33, thereby reducing the adsorption of water by the hair shaft 33.
[0031] Working Principle: During operation of the kitchen wastewater oil separation mechanism, wastewater is first supplied to the separation tank 1 through the inlet pipe 11. Simultaneously, the motor 2 drives the transmission rod 21 to rotate, which in turn drives the limiting component and connecting component to rotate synchronously with the bristle 33. As the bristle 33 rotates in the wastewater, the soft bristles on its outer surface absorb the grease. The bristle 33 then continues to rotate and enters the squeezing tank 41, where the grease adhering to the soft bristles is squeezed. The grease flows to the left through the guide plate 4 and enters the collection tank 51 through the fixed frame 5. The collection tank 51 collects the grease. After a certain amount of grease has been stored, the collection tank 51 and the fixed frame 5 can be separated by removing the pull-down bolt 53. The grease stored in the header 51 is cleaned. When replacing and cleaning the bristle rod 33, simply rotate the sliding sleeve 25. The external thread on the outside of the threaded sleeve 32 engages with the internal thread on the inside of the top of the sliding sleeve 25, causing the sliding sleeve 25 to move downward outside the fixed sleeve 22. This simultaneously causes the locking ring 26 to move downward, releasing the locking of the limiting ball 23. Then, the locking pin 3 can be pulled out of the fixed sleeve 22 for replacement. Afterward, rotate the sliding sleeve 25 in the opposite direction. The external thread on the outside of the threaded sleeve 32 engages with the internal thread on the inside of the top of the sliding sleeve 25, causing the sliding sleeve 25 to move upward outside the fixed sleeve 22. This squeezes the limiting ball 23, forcing it to move inward and engage with the locking groove 31, thus fixing the bristle rod 33.
