[0023] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Referring to Figures 1 to 4 , Figure 1 In an embodiment of the present utility model, it is a structural cross-sectional view, Figure 2 In an embodiment of the present utility model, it is for the Figure 1 enlarged view of structure A in Figure 3 In an embodiment of the present utility model, it is a three-dimensional view of the L-shaped mounting frame structure of the oilfield drilling wastewater decolorization treatment device, Figure 4 In an embodiment of the present utility model, it is a three-dimensional view of the filter plate and mounting block structure of the oilfield drilling wastewater decolorization treatment device. The oilfield drilling wastewater decolorization treatment device includes a decolorization tank 1 and a separation tank 17, and is characterized in that a filtering component is installed on the decolorization tank 1, and a control component and a separation component are installed on the decolorization tank 1.

[0025] A water outlet pipe is fixedly installed on the right side of the decolorization tank 1, and an observation window is installed on the front of the decolorization tank 1, which is convenient for the user to observe the amount of raw water input. Two handles are fixedly installed on the top of the filter frame 3.

[0026] The filtering component includes a water inlet cylinder 2 fixedly installed on the top of the decolorization tank 1. A filter frame 3 is clamped inside the water inlet cylinder 2. L-shaped mounting frames 4 are fixedly installed on both sides of the decolorization tank 1. Compression springs 5 are fixedly installed on one side of the two L-shaped mounting frames 4 facing each other.

[0027] On one side of the two compression springs 5 facing each other, L-shaped sliding plates 6 are fixedly installed. Sliding grooves are opened inside the two L-shaped mounting frames 4. The L-shaped sliding plates 6 are slidably connected to the L-shaped mounting frames 4 through the sliding grooves, providing guidance for the sliding of the L-shaped sliding plates 6 and making the movement of the L-shaped sliding plates 6 more convenient.

[0028] On opposite sides of the two L-shaped sliding plates 6, limiting blocks 7 are fixedly installed. On both sides of the filter box 3, clamping grooves are provided. The limiting blocks 7 are clamped with the filter box 3 through the clamping grooves, which facilitates the fixing and limiting of the filter box 3, and reduces the impact on the filter box 3 during the input of raw water, preventing the unstable installation of the filter box 3. Inside the two L-shaped sliding plates 6, T-shaped limiting rods 8 are inserted.

[0029] It should be noted that by installing the filtering component, it is convenient to filter the raw water input into the decolorization tank 1, reducing the situation of raw water carrying impurities into the tank, which in turn affects the quality of raw water decolorization. The filter box 3 can be disassembled and cleaned, improving the filtering efficiency of the filter box 3, and thus improving the efficiency and quality of raw water decolorization.

[0030] Specifically, when the filter box 3 needs to be disassembled and cleaned, the two L-shaped sliding plates 6 are successively toggled in opposite directions, causing the two compression springs 5 to be compressed, driving the L-shaped sliding plates 6 to fit with the L-shaped mounting frame 4. Subsequently, the T-shaped limiting rods 8 are inserted into the L-shaped mounting frame 4 to limit the L-shaped sliding plates 6. The user can take out the filter box 3 from the inside of the water inlet cylinder 2 through the handle for cleaning.

[0031] In this embodiment, the control component includes two support rods 9 fixedly installed on the top of the decolorization tank 1. On the top of the two support rods 9, a medicine adding tank 10 is fixedly installed. At the bottom of the medicine adding tank 10, a medicine outlet pipe 11 is fixedly installed. On the front of the medicine outlet pipe 11, a scale 12 is fixedly installed.

[0032] An extension hole is provided on the top of the decolorization tank 1. The medicine outlet pipe 11 passes through the extension hole and penetrates into the inside of the decolorization tank 1. On the outer side of the medicine outlet pipe 11, two electromagnetic valves are fixedly connected, which is convenient for controlling the dosage of the flocculating decolorizing agent input into the decolorization tank 1 and reducing waste.

[0033] A driving motor 13 is fixedly installed on the top of the decolorization tank 1. The output end of the driving motor 13 is fixedly installed with a stirring rod 14. A through hole is provided on the top of the decolorization tank 1. The output end of the driving motor 13 is fixedly connected with the stirring rod 14 through the through hole. When the driving motor 13 is started, the stirring rod 14 rotates synchronously.

[0034] On the outer side of the stirring rod 14, a stirring blade 15 is fixedly installed. On the outer side of the stirring rod 14, a scraping plate 16 is fixedly installed. When the stirring rod 14 rotates, the stirring blade 15 rotates, fully stirring and reacting the raw water and the flocculating decolorizing agent. The scraping plate 16 reduces the situation of raw water adhering to the inner wall of the decolorization tank 1.

[0035] The separation component includes two mounting blocks 18 fixedly installed inside the separation tank 17. A filter plate 19 is slidably mounted on one side of the two mounting blocks 18 facing each other. A liquid outlet pipe is fixedly installed on the right side of the separation tank 17, and a valve is installed on the outer side of the liquid outlet pipe to facilitate controlling the time for the liquid to drain out of the interior of the separation tank 17.

[0036] Sliders 20 are fixedly installed on both sides of the filter plate 19. Moving grooves are formed on one side of the two mounting blocks 18 facing each other. The sliders 20 are slidably connected to the mounting blocks 18 through the moving grooves. A connecting block 21 is fixedly installed on the top of the filter plate 19.

[0037] The user holds the connecting block 21 and pulls the filter plate 19 upward. The sliders 20 move in the moving grooves in the two mounting blocks 18, and then the filter plate 19 is pulled out of the separation tank 17 to clean the filter plate 19, thereby improving the service quality of the filter plate 19 and better filtering the raw water.

[0038] It should be noted that by installing a control component, it is convenient to accurately control the amount of flocculating decolorizing agent input according to the amount of raw water input, improve the quality of raw water decolorization, and reduce the waste of flocculating decolorizing agent.

[0039] Specifically, the supernatant is drawn off and put into the interior of the decolorization tank 1 through the water inlet cylinder 2. At the same time, the filter frame 3 filters the supernatant to reduce the impurities carried in the supernatant from being put into the interior of the tank together. Subsequently, by observing the amount of raw water in the decolorization tank 1, the solenoid valve above the medicine outlet pipe 11 is activated, so that the flocculating decolorizing agent in the dosing tank 10 flows into the interior of the medicine outlet pipe 11. The amount of the flocculating decolorizing agent flowing out is controlled by the scale 12. When a certain amount of the flocculating decolorizing agent has flowed out, the solenoid valve above the medicine outlet pipe 11 is closed, and the solenoid valve below the medicine outlet pipe 11 is activated, so that the flocculating decolorizing agent flows into the decolorization tank 1. At the same time, the drive motor 13 is activated to drive the stirring rod 14 and the scraper 16 to rotate, facilitating the full stirring reaction between the raw water and the flocculating decolorizing agent. The reacted raw water is discharged into the separation tank 17 through the water outlet pipe and is filtered and precipitated by the filter plate 19, so that the decolorized impurities are separated from the raw water, thereby obtaining clean raw water. Subsequently, the valve is activated, and the raw water is discharged from the separation tank 17 through the liquid outlet pipe.

[0040] The working principle of the above embodiment is as follows: When in use, raw water is put into calcium oxide for dissolution, and then precipitation is carried out. After precipitation, the solution directly enters the spiral dewatering machine, the sludge is directly transported out for harmless treatment, and the filtrate directly enters the acid precipitation tank for acid precipitation. After precipitation, the supernatant is pumped out and put into the interior of the decolorization tank 1 through the water inlet tube 2. At the same time, the filter frame 3 filters the supernatant to reduce the impurities carried in the supernatant from being put into the interior of the tank together. Then, by observing the amount of raw water in the decolorization tank 1, the solenoid valve above the chemical dosing pipe 11 is activated, so that the flocculating decolorizing agent in the chemical dosing tank 10 flows into the chemical dosing pipe 11, and the amount of the flocculating decolorizing agent flowing out is controlled by the scale 12;

[0041] When the flocculating decolorizing agent flows out to a certain amount, the solenoid valve above the chemical dosing pipe 11 is closed, and the solenoid valve below the chemical dosing pipe 11 is activated, so that the flocculating decolorizing agent flows into the interior of the decolorization tank 1, and at the same time, the drive motor 13 is activated to drive the stirring rod 14 and the scraping plate 16 to rotate, facilitating the full stirring reaction between the raw water and the flocculating decolorizing agent;

[0042] The raw water after the reaction is discharged into the separation tank 17 through the water outlet pipe, and is filtered and precipitated through the filter plate 19, so that the decolorized impurities are separated from the raw water, thereby obtaining clean raw water. Then, the valve is activated, and the raw water is discharged from the separation tank 17 through the liquid outlet pipe;

[0043] When it is necessary to disassemble and clean the filter frame 3, the two L-shaped sliding plates 6 are sequentially toggled in opposite directions, so that the two compression springs 5 are compressed, driving the L-shaped sliding plates 6 to fit with the L-shaped mounting frame 4. Then, the T-shaped limiting rod 8 is inserted into the L-shaped mounting frame 4 to limit the L-shaped sliding plates 6, and the user takes out the filter frame 3 from the interior of the water inlet tube 2 through the handle for cleaning.

[0044] The above is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
