Description

Technical Field

[0001] This utility model relates to the field of kitchen waste equipment technology, and in particular to a primary treatment device for kitchen wastewater. Background Technology

[0002] In daily life, kitchens generate a large amount of wastewater every day due to activities such as washing vegetables and dishes. This wastewater contains a lot of solid waste such as grease and food scraps. If discharged directly, it will not only be detrimental to the hygiene of the kitchen, but may also cause blockage of the sewer pipes, causing great inconvenience to people's lives.

[0003] Traditional kitchen wastewater treatment typically uses a single-layer filter screen, which is prone to clogging when large and small debris accumulates during actual use, resulting in significant limitations. Furthermore, it lacks effective treatment for grease, which not only affects water quality but may also cause corrosion and blockage of sewer pipes. To address these issues, this utility model provides a preliminary treatment device for kitchen wastewater. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a preliminary treatment device for kitchen wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A preliminary treatment device for kitchen wastewater includes a treatment tank. The treatment tank has a slot inside, and a connecting frame is inserted into the slot. A snap-fit ​​frame is fixedly connected to the upper surface of the connecting frame, and a coarse filter frame is inserted into the snap-fit ​​frame. A central pipe is fixedly connected to the middle of the lower surface of the treatment tank, and a fixed pipe is fixedly connected to the lower surface of the central pipe. A three-way valve is fixedly connected to the lower end of the fixed pipe, and a separation component is fixedly installed at the lower end of the three-way valve.

[0007] As a further improvement of this utility model, the separation assembly includes a separation tube fixedly installed at the lower end of the three-way valve pipe, an oil-absorbing pad is provided inside the separation tube, a threaded pipe is fixedly connected to the lower end of the three-way valve pipe, and an installation pipe adapted to the threaded pipe is fixedly connected to the upper end of the separation tube.

[0008] As a further improvement of this utility model, a flexible hose is fixedly connected to the lower surface of the separation tube, and a drain pipe is fixedly connected to the other end of the flexible hose.

[0009] As a further improvement of this utility model, the surface of the connecting frame is provided with several fine filter grooves.

[0010] As a further improvement of this utility model, a first connecting plate is fixedly connected to both sides inside the snap-fit ​​frame, and a second connecting plate is fixedly connected to both sides inside the coarse filter frame.

[0011] As a further improvement of this utility model, a connecting pipe is fixedly connected to one side of the three-way valve pipe, and the other end of the connecting pipe is fixedly connected to the drain pipe. A handle is provided on the surface of the three-way valve pipe.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating a connecting frame and a coarse filter frame, the dual filtration structure of the coarse filter frame and fine filter tank allows the device to effectively filter large and small debris in kitchen wastewater in stages, ensuring that the wastewater entering subsequent treatment stages is relatively pure. This reduces the difficulty and cost of subsequent treatment and avoids clogging. The device also features a detachable snap-fit ​​frame and coarse filter frame, which can be easily removed for cleaning via the first and second connecting plates. This simplifies equipment maintenance, reduces maintenance costs, and improves the hygiene performance and service life of the equipment.

[0014] By incorporating a separation component, the device can automatically adjust its treatment path based on the oil content in the wastewater through the flexible rotation of the three-way valve. When there is a high amount of oil, the wastewater is guided to the separation pipe for oil separation. The oil-absorbing pad inside the separation pipe has excellent oil absorption performance, which can quickly absorb the oil in the wastewater, facilitating subsequent wastewater treatment or reuse and effectively improving the efficiency of oil treatment. When the oil content is low, the wastewater is directly discharged into the drain pipe through the connecting pipe, avoiding unnecessary treatment steps and saving resources and time.

[0015] By incorporating a threaded tube, the design of the connection between the installation tube and the threaded tube, along with the flexibility of the hose, makes it easy and quick to replace the oil-absorbing pad. There is no need to disassemble the entire device; simply rotate the installation tube to easily remove the separator tube and replace the oil-absorbing pad, reducing maintenance costs and difficulty.

[0016] In summary, this utility model has a compact structure, small footprint, and features flexible oil treatment, efficient oil separation mechanism, easy maintenance and replacement, environmental protection and energy saving. At the same time, the connection design between the components is reasonable and easy to install. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A preliminary treatment device for kitchen wastewater includes a treatment tank 1. The treatment tank 1 has a slot 2 inside, and a connecting frame 3 is inserted into the slot 2. A snap-fit ​​frame 4 is fixedly connected to the upper surface of the connecting frame 3. A coarse filter frame 5 is inserted into the snap-fit ​​frame 4. A central pipe 6 is fixedly connected to the middle of the lower surface of the treatment tank 1. A fixed pipe 7 is fixedly connected to the lower surface of the central pipe 6. A three-way valve pipe 8 is fixedly connected to the lower end of the fixed pipe 7. A separation component is fixedly installed at the lower end of the three-way valve pipe 8.

[0024] In this utility model, the separation component includes a separation pipe 9 fixedly installed at the lower end of a three-way valve pipe 8. The separation pipe 9 has an oil-absorbing pad 10 inside, which has strong oil absorption capacity and good durability, ensuring a long-lasting and stable oil separation effect. A threaded pipe 11 is fixedly connected to the lower end of the three-way valve pipe 8. The design of the threaded pipe 11 facilitates the quick installation and disassembly of the separation pipe 9, improving the ease of equipment maintenance. An installation pipe 12 that is compatible with the threaded pipe 11 is fixedly connected to the upper end of the separation pipe 9. The tight fit between the installation pipe 12 and the threaded pipe 11 ensures the sealing during the oil separation process and prevents sewage leakage. A hose 13 is fixedly connected to the lower surface of the separation pipe 9. The hose 13 has good flexibility and can adapt to the installation requirements of different angles and positions, ensuring smooth drainage. A drain pipe 14 is fixedly connected to the other end of the hose 13.

[0025] Several fine filter grooves 15 are opened on the surface of the connecting frame 3. The fine filter grooves 15 are evenly distributed and have a moderate pore size, which can effectively intercept small impurities in sewage and improve the filtration effect. The first connecting plate 16 is fixedly connected to both sides inside the snap-fit ​​frame 4. The second connecting plate 17 is fixedly connected to both sides inside the coarse filter frame 5. A connecting pipe 18 is fixedly connected to one side of the three-way valve pipe 8. The connecting pipe 18 serves as a backup drainage path. When the oil content is low, the three-way valve pipe 8 can be rotated to drain directly, which improves the flexibility of the equipment. The other end of the connecting pipe 18 is fixedly connected to the drain pipe 14. The surface of the three-way valve pipe 8 is provided with a handle 19. The design of the handle 19 makes it easy for users to operate the three-way valve pipe 8 and easily switch paths, which improves the ease of use of the equipment.

[0026] In use, kitchen wastewater enters the treatment tank 1 and first passes through the coarse filter frame 5 inside the snap-fit ​​frame 4. Large debris is filtered by the coarse filter frame 5. Then, it passes through the fine filter groove 15 of the connecting frame 3 and enters the collection pipe 6. Small debris remains in the connecting frame 3. Then, the wastewater enters the fixed pipe 7 from the collection pipe 6. When there is a lot of oil in the wastewater, turn the three-way valve pipe 8 to let it pass through the threaded pipe 11 and enter the separation pipe 9. The oil in the wastewater will be absorbed by the oil-absorbing pad 10 in the separation pipe 9. The separated wastewater enters the drain pipe 14 through the hose 13. When there is a lot of oil in the wastewater... When the content is low, rotate the three-way valve pipe 8 to allow it to enter the drain pipe 14 directly from the connecting pipe 18. After the device is used up, remove the snap-fit ​​frame 4 and the coarse filter frame 5 through the first connecting plate 16 and the second connecting plate 17 respectively to clean the debris on them. When the oil absorbent pad 10 absorbs a lot of oil, rotate the installation pipe 12 on the separator pipe 9 to remove it from the threaded pipe 11 under the three-way valve pipe 8 and replace the oil absorbent pad 10 inside. The hose 13 under the installation pipe 12 can allow the installation pipe 12 to rotate. When reinstalling, rotate the hose 13 in advance.
