Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment for spraying workshops, and in particular to a sewage treatment device with solid-liquid separation function for spraying workshops. Background Art

[0002] In the utility model patent application with application publication number CN216687820U, a filtering mechanism and a purification mechanism are included. The filtering mechanism includes a filtering tank and a filtering assembly. The bottom wall of the filtering tank is provided with an outlet pipe. The filtering assembly includes a horizontally arranged filter screen and an installation frame. The side wall of the filtering tank has a horizontally penetrating first slide groove. The first slide groove accommodates the sliding of the installation frame. The installation frame includes an upper frame body and a lower frame body that are flipped and connected. The upper frame body and the lower frame body cooperate to clamp and fix the filter screen; the purification mechanism includes a decomposition tank and a sedimentation tank. The decomposition tank is located below the outlet pipe. The decomposition tank is filled with a dissolving agent for decomposing sewage. A connecting pipe is provided between the decomposition tank and the sedimentation tank. The connecting pipe is provided with a water pump. A microbial sludge layer is provided at the bottom of the sedimentation tank. A drain valve is provided on the side wall of the sedimentation tank. The drain valve is located above the microbial sludge layer. The advantage is that the filter screen can be easily replaced.

[0003] The wastewater used in the spray workshop contains oil and granular impurities. Since the density of oil is lower than that of water, there will be a layer of oil and small-density impurities floating on the wastewater. If you only rely on solvents and sedimentation tanks, you cannot decompose the wastewater very well. However, if you can separate the solids and liquids in the wastewater, separate the solids, oily liquids and water in the wastewater and treat them separately, then it will be easier to meet the discharge standards, thereby increasing the efficiency of wastewater treatment. Summary of the invention

[0004] The problem to be solved by the present invention is that the particles precipitated in the sewage are difficult to handle and remain, which makes subsequent sewage treatment difficult, and a layer of oily substances and impurities float on the sewage, which are difficult to decompose.

[0008] Preferably, a baffle is installed on one side of the inner wall of the sewage sedimentation tank, an oil receiving block is installed on one end of the baffle, the inner wall of the oil receiving block is connected to an oil guide pipe, one end of the oil guide pipe is connected to an oil storage tank, a water inlet is provided on the top of the outer wall of the sewage sedimentation tank, and a water outlet is provided on the bottom of the outer wall of the sewage sedimentation tank.

[0011] Preferably, the oil scraper blade is connected to the bottom of the outer wall of the bottom connecting rod, and the installation angle of the oil scraper blade is inclined, and the inclination angle of the oil scraper blade is 5°.

[0012] Preferably, one end of the connecting rod is connected to the outer wall of the driven bevel gear, and the other end of the connecting rod is connected to the outer wall of the wind wheel.

[0013] Preferably, the inner wall of the linkage shaft is provided with a cavity, and the cavity of the linkage shaft is inclined.

[0014] Preferably, one end of the rotating rod is connected to the inner wall of the linkage shaft, one end of the air pipe is connected to the inner wall of the linkage shaft, and the rotating rod and the air pipe form a transmission connection through the linkage shaft.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] (1) In the traditional sewage treatment process, particulate matter precipitated at the bottom of the pool is often difficult to be effectively removed, which not only affects the efficiency of sewage treatment, but may also cause the treated water quality to be substandard. The present invention sets an air pipe and a wind wheel at the bottom of the sewage sedimentation tank, and uses the wind force generated by the wind wheel to blow the precipitated residue so that it is suspended from the bottom of the pool, which is convenient for subsequent suction and filtration treatment. This design cleverly utilizes the effect of wind power, avoids traditional mechanical stirring or manual cleaning methods, reduces energy consumption and operating costs, and improves treatment efficiency. Through the suction effect of the pumping equipment, the suspended residue is sucked into the filter through the pumping pipe, and the residue is separated from the water by the filter screen, realizing solid-liquid separation, making the treated sewage clearer and reducing the burden of subsequent treatment. In addition, the residue in the filter is cleaned regularly to ensure the continuous and stable operation of the equipment and improve the degree of automation of the entire sewage treatment process;

[0017] (2) The wastewater generated in the spraying workshop often contains a large amount of oily substances and impurities. These substances form an oil film on the water surface, which is not only difficult to decompose naturally, but also poses a challenge to traditional sewage treatment. The device sets up the structure of the scraper blade and the diversion channel, and uses the linkage mechanism driven by the motor to make the scraper blade scrape along the bottom of the inner wall of the sewage sedimentation tank, scraping the oil floating on the water surface to the baffle plate on one side, and then guiding the oil into the oil storage tank through the oil receiving block and the oil guide pipe for centralized treatment. The design angle of the scraper blade and the setting of the diversion channel make it possible for the oil to flow smoothly into the diversion channel even when the scraper blade is tilted, and further scraped off by the baffle plate, effectively removing the oily substances in the sewage. This design not only improves the efficiency of oil-water separation, but also avoids the influence of oily substances on the sewage treatment effect, thereby ensuring the quality of sewage treatment.

[0037] The teeth of the linkage wheel 6 and the driven wheel 8 mesh with each other, and the linkage wheel 6 and the driven wheel 8 form a transmission connection through the linkage rod 7. When the linkage wheel 6 rotates, it will drive the linkage rod 7 to rotate, and the driven wheel 8 will also rotate at the same time.

[0038] A cylindrical clamping block is provided at one end of the linkage block 9. The diameter of the clamping block provided at one end of the linkage block 9 is adapted to the diameter of the inner wall of the bottom connecting rod 10. When the linkage block 9 rotates, it drives the bottom connecting rod 10 to rotate through its clamping block.

[0039] The oil scraper 11 is connected to the bottom of the outer wall of the bottom link 10. The installation angle of the oil scraper 11 is inclined. The inclination angle of the oil scraper 11 is 5°. When the oil flows into the diversion channel 12, it will flow to the other side of the oil scraper 11 due to the inclination of the oil scraper 11.

[0040] One end of the connecting rod 16 is connected to the outer wall of the driven bevel gear 15, and the other end of the connecting rod 16 is connected to the outer wall of the wind wheel 17. The driven bevel gear 15 will drive the wind wheel 17 to rotate through the connecting rod 16, and the wind wheel 17 will form an air duct and blow the air to the bottom when rotating.

[0041] The inner wall of the linkage shaft 4 is provided with a cavity, and the cavity of the linkage shaft 4 is inclined. The wind guide shell 18 can guide the wind blown out by the wind wheel 17 to the outer wall of the linkage shaft 4, and the inner wall of the linkage shaft 4 is provided with a cavity in an inclined shape, and the wind will be blown into the inner wall of the air pipe 5 through the cavity of the linkage shaft 4.

[0042] One end of the rotating rod 3 is connected to the inner wall of the linkage shaft 4, and one end of the air pipe 5 is connected to the inner wall of the linkage shaft 4. The rotating rod 3 and the air pipe 5 form a transmission connection through the linkage shaft 4. After the motor 2 is started, the rotating rod 3 will be driven to rotate, and the rotating rod 3 will drive the air pipe 5 to rotate through the linkage shaft 4.

[0043] The working principle and use process of the present invention are as follows: first, the user guides the sewage from the water inlet 29 to the inner wall of the sewage sedimentation tank 1. After the sewage is precipitated in the sewage sedimentation tank 1, the oil in the sewage will float on the water surface, and the residue will sink to the bottom of the inner wall of the sewage sedimentation tank 1. Then the motor 2 can be started. After the motor 2 is started, the rotating rod 3 will be driven to rotate, and the rotating rod 3 will drive the air pipe 5 to rotate through the linkage shaft 4. When the air pipe 5 rotates, it will drive the linkage wheel 6 to rotate. When the linkage wheel 6 rotates, it will drive the driven wheel 8 to rotate. The synchronous linkage rod 7 will also rotate synchronously. When the linkage rod 7 rotates, it will drive the linkage block 9 to rotate. The linkage block 9 will drive the bottom connecting rod 10 to rotate while causing the bottom connecting rod 10 to rotate slightly. The rod 10 is connected to the oil scraper blade 11, so the oil scraper blade 11 will also have a synchronous motion trajectory with the bottom connecting rod 10. When the oil scraper blade 11 rotates, it can scrape the oil on the water surface. When the oil scraper blade 11 rotates to the baffle plate 25 set on one side of the inner wall of the sewage sedimentation tank 1, the baffle plate 25 can scrape the oil on the outer wall of the oil scraper blade 11 and guide it to the oil receiving block 26, and then discharge it into the oil storage tank 28 through the oil guide pipe 27 for centralized treatment. At the same time, in order to prevent one side of the oil scraper blade 11 from being scratched by the baffle plate 25 due to the relationship between parts, the installation angle of the oil scraper blade 11 is slightly inclined, and a diversion channel 12 is provided. When the oil flows into the diversion channel 12, due to the inclination of the oil scraper blade 11, it will flow to the other side of the oil scraper blade 11, so that it can be scraped by the baffle plate 25;

[0044] Secondly, when the air pipe 5 rotates, it will also drive the active bevel gear 13 to rotate. When the active bevel gear 13 rotates, it will drive the driven bevel gear 15 to rotate through the differential 14. At the same time, due to the setting of the differential 14, the rotation speed of the driven bevel gear 15 is different from that of the active bevel gear 13, and the rotation speed of the driven bevel gear 15 will be faster, and the driven bevel gear 15 will drive the wind wheel 17 to rotate through the connecting rod 16. When the wind wheel 17 rotates, it will form an air duct and blow the air to the bottom. The bottom of the wind wheel 17 is exactly the linkage shaft 4, and the outer wall of the linkage shaft 4 is installed with an air guide shell 18. The air guide shell 18 can guide the wind blown out by the wind wheel 17 to the outer wall of the linkage shaft 4, and the inner wall of the linkage shaft 4 is provided with a cavity in an inclined shape. The wind will be blown into the inner wall of the air pipe 5 through the cavity of the linkage shaft 4 and discharged through one end of the air pipe 5;

[0045] Finally, since one end of the air pipe 5 is at the bottom of the inner wall of the sewage sedimentation tank 1, the air discharged from the bottom of the inner wall of the sewage sedimentation tank 1 will blow the residue settled at the bottom of the sewage sedimentation tank 1, so that the residue floats up. At this time, the user can start the pumping equipment 20 installed at one end of the bottom rod 19. After starting, the pumping equipment 20 will absorb water and residue through the pumping pipe 21 and the pumping head 22, and discharge them into the inner wall of the filter 23 through the pumping pipe 21. The inner wall of the filter 23 is provided with a filter screen 24. The water flow will be discharged through the filter screen 24, and the residue will be stuck on the outer wall of the filter screen 24. The user only needs to open the filter 23 regularly to pour out the residue. After the sewage treatment is completed, the user can discharge the treated sewage from the outlet 30. At this point, the work of the present invention is completed.
