Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a high-efficiency pretreatment device for water pollution. Background Technology

[0002] In water quality analysis, COD, dissolved oxygen, and turbidity are three core indicators.

[0003] A COD analyzer is used to determine the amount of oxygen equivalent consumed when organic matter and inorganic reducing substances in water are oxidized by strong oxidants, reflecting the degree of organic pollution in the water body.

[0004] Dissolved oxygen analyzers are used to measure the concentration of dissolved oxygen in water, reflecting the water body's self-purification capacity, the living conditions of aquatic organisms, and the aeration effect of wastewater treatment.

[0005] A turbidimeter is used to measure the degree of light scattering by suspended particles in water, reflecting the clarity of the water, the filtration effect, or the sedimentation efficiency.

[0006] For wastewater containing large particles, oil, and high concentrations of suspended solids, directly using the aforementioned instruments for measurement will significantly interfere with the measurement results and shorten the lifespan of the measuring instruments. Utility Model Content

This device can remove large particles from wastewater, separate oil and water, and treat high-concentration suspended solids, enabling analytical instruments to operate stably, protecting the instruments, and extending their service life.

[0008] A high-efficiency pretreatment device for water pollution includes a cyclone separator and a vibrating membrane filter. The cyclone separator includes a tank.

The height of the drain pipe is higher than the height of the top wall of the partition plate. The height of the liquid level sensor is higher than the height of the top end of the drain pipe. A drain valve is installed at the top end of the drain pipe.

[0012] The bottom wall of the tank is provided with a drain hole, and a water pump is connected to the drain hole. The output end of the water pump is connected to the water inlet of the vibrating membrane filter through a water pipe.

[0013] Preferably, the bottom end of the drain pipe is sealed by a sealing plate, the sealing plate has a bottom drain hole, and the side wall of the drain pipe is provided with a plurality of longitudinally separate side drain hole groups.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a high-efficiency pretreatment device for water pollution, characterized in that it includes a cyclone separator and a vibrating membrane filter. The cyclone separator includes a tank 1.

[0028] The tank 1 has a partition 4 that divides the inner cavity of the tank 1 into an upper cavity and a lower cavity. A water inlet pipe is connected to the top of the upper cavity, and a rotating paddle 3 is installed inside the upper cavity. A motor 2 is installed on the top wall of the tank 1, and the output shaft of the motor 2 enters the tank 1 and is connected to the rotating paddle 3. A liquid level sensor 8 is installed on the side wall of the upper cavity.

[0029] The partition 4 has a discharge hole, and the discharge pipe 6 includes a vertical section, an arc-shaped section, and a horizontal section. The arc-shaped section connects the vertical section and the horizontal section. The top of the vertical section is connected to the discharge hole. The horizontal section passes through the side wall of the tank 1. A discharge valve is installed inside the discharge pipe 6.

[0030] A filter plate 5 is installed in the lower cavity. The filter plate 5 is made of an oleophilic and hydrophobic material. The bottom end of the drain pipe 7 is located in the lower cavity and above the filter plate 5. The top end of the drain pipe 7 passes through the bottom wall of the arc-shaped section and the vertical section to enter the upper cavity. The height of the drain pipe 7 is higher than the height of the top wall of the partition 4. The height of the liquid level sensor 8 is higher than the height of the top end of the drain pipe 7. A drain valve 9 is installed at the top end of the drain pipe 7.

[0031] The bottom wall of the tank 1 is provided with a drain hole, and a water pump is connected to the drain hole. The output end of the water pump is connected to the water inlet of the vibrating membrane filter through a water pipe.

[0032] In this embodiment, through the cooperation of various components, wastewater enters through the inlet pipe during use. The motor 2 is started, and the motor 2 drives the rotating paddle 3 to rotate, thereby causing the wastewater to rotate and settle. This causes large particles to settle onto the baffle 4, while oil floats on the surface, performing primary separation. After separation, the drain valve is opened, and the water layer is discharged into the lower chamber through the drain pipe 7. After being processed by the filter plate 5, which is made of oleophilic and hydrophobic material, it can further remove emulsified oil and small oil droplets. The wastewater then enters the water pump through the drain hole. The water pump discharges the wastewater to the vibrating membrane filter device. The vibrating membrane filter device uses high-frequency vibration to generate shear force, reducing the formation of filter cake layer and concentration difference. After the wastewater is treated in this way, it enters the analytical instrument, enabling the analytical instrument to operate stably, protecting the analytical instrument, and extending its service life.

[0033] In this embodiment, the height of the drain pipe 7 is higher than the height of the top wall of the partition 4. After settling, large particles are located on the partition 4 and below the top of the drain pipe 7. When the drain pipe 7 drains, the settled particles can be avoided.

[0034] In this embodiment, a liquid level sensor 8 is installed on the side wall of the upper chamber. The height of the liquid level sensor 8 is higher than the top of the drain pipe 7. After the liquid level drops below the liquid level sensor 8, the control system controls the drain valve to close, which can prevent the oil layer from being discharged into the lower chamber. This can prevent large particles and oil layer after primary separation from being discharged into the lower chamber.

[0035] After the sewage in the upper chamber is discharged, the discharge valve can be opened to discharge the particulate matter, remaining sewage, and oil layer in the upper chamber.

[0036] In this embodiment, the bottom end of the drain pipe 7 is sealed by a sealing plate, and a bottom drain hole is opened on the sealing plate. The side wall of the drain pipe 7 is provided with a plurality of longitudinally separate side drain hole groups. Each side drain hole group includes a plurality of side drain holes distributed along the circumference of the drain pipe 7, and a side drain pipe 10 is connected to each side drain hole.

[0037] In this embodiment, the side drain pipe 10 is inclined downwards in the direction from the drain pipe 7 toward the side wall of the tank 1.

[0038] In this embodiment, the side drain pipe 10 with higher height has a closer distance between its drain end and the inner wall of the tank 1.

[0039] In this embodiment, several side drain pipes 10 are provided, which allows the discharged sewage to be distributed over a wider area on the filter plate 5, resulting in a better filtration effect of the filter plate 5.

[0040] This embodiment also includes a bottom fixing block 11, which is connected to the inner wall of the tank 1 via a connecting rod 12. The bottom end of the rotating paddle 3 is rotatably connected to the bottom fixing block 11. In this embodiment, the rotating paddle 3 is rotatably mounted on the bottom fixing block 11 to improve the stability of the rotation of the rotating paddle 3.

[0041] In this embodiment, the top wall of the baffle 4 slopes downwards from all sides of the discharge hole towards the discharge hole. This slope facilitates the discharge of all settled particles.

[0042] In this embodiment, the height of the liquid level sensor 8 is 10-15 cm higher than the top of the drain pipe 7, and the top of the drain pipe 7 is 10-15 cm higher than the top wall of the partition 4. This 10-15 cm height difference completely prevents particulate matter and oil from being discharged into the lower chamber after primary separation.

[0043] In this embodiment, the tank 1 is supported by multiple support columns.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
