[0002] In the process of oil extraction and processing, since crude oil contains a small amount of phenolic compounds, alkaline substances are added for neutralization during the desalting and dehydration process. The phenolic compounds react with sodium hydroxide to produce sodium phenolate, resulting in sodium phenolate in the wastewater. Sodium phenolate wastewater is an industrial wastewater containing high concentrations of phenol and its derivatives.

DETAILED DESCRIPTION

[0030] like Figure 2As shown, the liquid pumping assembly includes a liquid pump 31 and a connecting pipe 32. Three liquid pumps 31 are evenly spaced and connected to the rear side of the processing frame 1. The liquid inlet end and the liquid outlet end of the liquid pump 31 are both connected to the connecting pipe 32. The liquid inlet end of the liquid pump 31 is arranged on the right side, and the liquid outlet end of the liquid pump 31 is arranged on the left side. The connecting pipes 32 on both sides of the liquid pump 31 are respectively connected to two chambers close to it, so that the liquid pump 31 can discharge the sewage in the right chamber into the left chamber through the connecting pipe 32 when it is in operation, and the connecting pipe 32 on the left side of the left liquid pump 31 is aligned with the top of the material guide frame 5.

[0031] like Figure 2 As shown, the electrolytic assembly includes a connection frame 41, a conductive plate 42 and a connection wire 43. The connection frame 41 is connected to the upper left side of the leftmost chamber, and the front and rear sides of the connection frame 41 are connected to the conductive plate 42. The lower part of the conductive plate 42 extends into the leftmost chamber, and the conductive plate 42 is connected to the connection wire 43.

[0032] like Figure 4 and Figure 5 As shown, the unloading mechanism includes an unloading barrel 81, an outer barrel 82, a feeding block 83, a gear ring 84, a bottom plate 85, a connecting rod 86, an elastic member 87, a connecting rack 88 and a top plate 89. The top of the cover 21 is connected to the unloading barrel 81, the lower part of the unloading barrel 81 is connected to the outer barrel 82, the outer barrel 82 passes through the cover 21 and extends into the processing frame 1, the bottom of the unloading barrel 81 is connected to the top plate 89, the right side of the top plate 89 is provided with a discharge port, the bottom of the outer barrel 82 is connected to the bottom plate 85, the left side of the bottom plate 85 is provided with a discharge port, and the outer barrel 82 is rotatably connected to the feeding block 83. Two injection grooves are evenly spaced on the feeding block 83, the top of the injection groove can be rotated to align with the discharge port, and the bottom of the injection groove can be rotated to align with the discharge port. The outer ring of the feeding block 83 is connected to a ring gear 84 through a one-way clutch, and a connecting rack 88 is slidably connected to the right side of the outer cylinder 82, and the connecting rack 88 is meshed with the ring gear 84. A connecting rod 86 is connected to the front side of the connecting rack 88, and the connecting rod 86 is slidably connected to the outer cylinder 82. An elastic member 87 is connected between the connecting rod 86 and the outer cylinder 82, and the elastic member 87 is a compression spring.

[0033] When sodium phenolate wastewater needs to be treated, the device can be used for treatment. Initially, sodium hydroxide, coagulant and flocculant are added into three discharge barrels 81 from right to left respectively. The reagents in the discharge barrel 81 will enter the injection slot through the discharge port. When in use, the pipeline of sodium phenolate wastewater is first connected to the liquid inlet pipe 7, and then the sodium phenolate wastewater will enter the rightmost chamber through the liquid inlet pipe 7. After it is full, the addition of sodium phenolate wastewater is stopped, and then the connecting rod 86 on the right side can be pulled forward to move the elastic member 87 forward. When the connecting rod 86 on the right side moves forward, it drives the connecting rack 88 When the connecting rack 88 moves forward, the connecting rack 88 moves forward to drive the gear ring 1 84 to rotate, and the rotation of the gear ring 1 84 will drive the feeding block 83 to rotate. When the connecting rack 88 moves to be separated from the gear ring 1 84, the feeding block 83 just rotates 180 degrees. At this time, the medicine in the feeding block 83 will be added to the chamber, thereby achieving the effect of adding medicine. After the medicine is added, the connecting rack 88 is released. At this time, under the action of the elastic member 1 87, the connecting rack 88 is reset to drive the gear ring 1 84 to reverse. At this time, under the action of the one-way clutch, the feeding block 83 will not rotate, and the medicine will be mixed with the dirt in the chamber after being added to the chamber. The water reacts, and after the reaction, the liquid pump 31 can be controlled to operate to send the sewage into the next chamber through the connecting pipe 32, and then the connecting rod 86 is pulled to move according to the above operation to add the reagent, and this is repeated. After passing through the three chambers on the right, the sewage will react with sodium hydroxide, coagulant and flocculant in turn, so that the phenolic substances in the sewage react with the alkali to form sodium phenol salt, and then the pollutants in the sewage are formed into flocs through the coagulant, and finally the flocs are connected to each other into flocs through the flocculant. When the liquid pump 31 on the left is in operation, the sewage and flocs can be transported to the next chamber through the connecting pipe 32. Above the material guide frame 5, the flocs will be blocked by the filter screen 6, and the sewage will pass through the filter screen 6 into the leftmost chamber. At this time, the connecting wire 43 can be connected to the power supply to make the conductive plate 42 discharge, and the mineralized residual difficult-to-degrade organic matter in the sewage can be decomposed, thereby purifying the water quality and making the sewage reach the discharge standard. Subsequently, the valve at the drain outlet is opened to discharge the purified water. In this way, the device can be used for sewage treatment, and during operation, sodium hydroxide, coagulant and flocculant can be added quantitatively without manual weighing and addition, which is more convenient to operate.

[0034] like Figure 6As shown, an impurity cleaning mechanism is also included, which includes a material guide barrel 91, a spiral feed disc 92, a screen 93, a drive motor 94 and a material guide plate 95. The material guide barrel 91 is connected to the right cover 21, and the material guide barrel 91 is communicated with the liquid inlet pipe 7. A drive motor 94 is installed on the top of the material guide barrel 91, and a spiral feed disc 92 is connected to the output shaft of the drive motor 94. The spiral feed disc 92 is located in the material guide barrel 91, and a screen 93 is connected to the bottom of the material guide barrel 91. The material guide plates 95 are connected to the front and rear sides of the upper part of the material guide barrel 91. The front and rear sides of the upper part of the material guide barrel 91 are opened, and the upper part of the spiral feed disc 92 is aligned with the opening, and the opening is aligned with the material guide plate 95.

[0035] When sewage is added, the sewage will first enter the guide barrel 91, and the impurities mixed in the sewage will be blocked by the screen 93, while the sewage will pass through the screen 93. Then, the driving motor 94 can be controlled to drive the spiral feed plate 92 to rotate. When the spiral feed plate 92 rotates, the impurities on the screen 93 will be transported upward. After being transported to the top of the guide barrel 91, they will pass through the opening above the guide barrel 91 and enter the guide plate 95, and be discharged through the guide plate 95. In this way, the impurities mixed in the sewage can be processed.

[0036] like Figure 7 As shown, a transmission mechanism is also included, and the transmission mechanism includes a floating frame 101, a guide rod 102, a pressure frame 103 and an extrusion rod 104. The left and right sides of the bottom of the cover 21 are connected with guide rods 102, and the floating frame 101 is slidably connected between the two guide rods 102. The floating frame 101 can slide up and down in the chamber. The extrusion rod 104 is connected to the rear side of the top of the floating frame 101, and the pressure frame 103 is connected to the rear side of the connecting rack 88. When the extrusion rod 104 moves upward, it will contact the pressure frame 103 and squeeze the pressure frame 103 to move.

[0037] When sewage enters the chamber, the buoyancy of the sewage will drive the floating frame 101 to move upward, and the floating frame 101 will drive the extrusion rod 104 to move upward when moving upward. The extrusion rod 104 will contact the pressure frame 103 when moving upward and squeeze the pressure frame 103 to move forward. The pressure frame 103 moves forward and drives the connecting rack 88 to move forward. In this way, the effect of automatically driving the connecting rack 88 to move can be achieved, which is more convenient to operate.

[0038] like Figure 8As shown, it also includes a controlled feeding mechanism, which includes an L-shaped rack 111, a sealing frame 112, a sealing plate 113 and a second gear ring 114. The right side of the floating frame 101 is connected to the L-shaped rack 111, and the left side of the liquid inlet pipe 7 is connected to the sealing frame 112. The sealing frame 112 is rotatably connected to the sealing plate 113. After the sealing plate 113 rotates 180 degrees, it can cooperate with the sealing plate 113 to block the liquid inlet pipe 7. The outer side of the sealing plate 113 is connected to the second gear ring 114, and the second gear ring 114 is located at the moving track of the L-shaped rack 111, so that the L-shaped rack 111 can drive the second gear ring 114 to rotate when moving.

[0039] When the floating frame 101 moves upward, it will drive the L-shaped rack 111 to move upward. When moving upward, the L-shaped rack 111 will mesh with the ring gear 114 and drive the ring gear 114 to rotate. When the ring gear 114 rotates, it will drive the blocking plate 113 to rotate. When the blocking plate 113 rotates, it will gradually cooperate with the blocking frame 112 to block the inside of the liquid inlet pipe 7. At this time, the chamber is already full of sewage. In this way, the liquid inlet pipe 7 can be automatically blocked after the chamber is filled with sewage.

[0040] like Figure 8 As shown, a locking mechanism is also included, which includes a clamping plate 121, a clamping column 122 and an elastic member 123. The clamping plate 121 is connected to the right rear side of the top of the rightmost floating frame 101, and a socket is provided on the upper part of the clamping plate 121. The lower right side of the rightmost discharge barrel 81 is slidably connected to the clamping column 122. The rear side of the clamping column 122 is a frustum shape. The upward movement of the clamping plate 121 will squeeze the conical surface on the clamping column 122. An elastic member 123 is connected between the clamping column 122 and the discharge barrel 81, and the elastic member 123 is a connecting spring.

[0041] When the floating frame 101 moves up, it will drive the card plate 121 to move up. After moving up, the card plate 121 will pass through the sealing cover 21 and contact the card column 122. When the card plate 121 moves up to contact the conical surface of the card column 122, the card plate 121 continues to move up and squeezes the card column 122 forward through the conical surface. The elastic member 123 is compressed until the socket on the card plate 121 moves to align with the card column 122. At this time, under the action of the elastic member 123, the card column 122 is reset and stuck in the socket, thereby fixing the card plate 121 and the floating frame 101. After the sewage in the chamber has been processed and discharged, the card column 122 can be pulled out of the socket. In this way, it is possible to avoid the floating frame 101 moving downward when the sewage is not completely discharged, causing the sealing plate 113 to rotate.

[0042] like Fig. 9As shown, it also includes a stirring rod 131 and a servo motor 132. The servo motor 132 is installed on the right side outside the processing frame 1. The output shaft of the servo motor 132 passes through the processing frame 1 and is connected to the stirring rod 131. The stirring rod 131 is located in the three chambers on the right side, and the left side of the stirring rod 131 is rotatably connected to the leftmost partition plate 2.

[0043] After the reagent is added into the chamber to react with the sewage, the servo motor 132 can be controlled to drive the stirring rod 131 to rotate. The stirring rod 131 can stir the sewage and the reagent in the chamber when rotating, so that the sewage and the reagent can react better.

[0044] like Fig.10 As shown, it also includes a lifting mechanism, which includes a guide sleeve 141, a connecting rope 142, a pull rod 143 and a floating block 144. The front side of the right cover 21 is connected to the guide sleeve 141, and the pull rod 143 is slidably connected in the guide sleeve 141. The connecting rope 142 is connected between the top of the pull rod 143 and the front side of the clamping column 122. A part of the connecting rope 142 is located in the guide sleeve 141, so that the guide sleeve 141 can guide the connecting rope 142. The bottom of the pull rod 143 is connected to the floating block 144.

[0045] When there is sewage in the rightmost chamber, the sewage will drive the float 144 to float up. At this time, the float 144 will not pull the card column 122. After all the sewage is discharged, the float 144 sinks and pulls the pull rod 143 downward. The pull rod 143 moves downward and pulls the card column 122 forward through the connecting rope 142. In this way, after the sewage is discharged, the card column 122 can be automatically pulled forward and separated from the card plate 121. There is no need to manually operate the card column 122 to move, and the operation is more convenient.

[0046] This embodiment also provides a method for electro-oxidation treatment of sodium phenol wastewater, and the specific steps are as follows: S1: Sodium hydroxide, coagulant and flocculant are added into three lower barrels 81 from right to left respectively, and the reagents in the lower barrels 81 enter the injection slot through the discharge port; S2: Connect the pipe of sodium phenolate wastewater to the liquid inlet pipe 7, and the sodium phenolate wastewater will enter the rightmost chamber through the liquid inlet pipe 7; S3: Pull the right connecting rod 86 forward, the elastic member 1 87 is compressed, and the connecting rod 86 moves forward, driving the connecting rack 88 forward, driving the gear ring 1 84 to rotate, and the rotation of the gear ring 1 84 drives the feeding block 83 to rotate, until the connecting rack 88 moves and disengages from the gear ring 1 84, and the feeding block 83 rotates 180 degrees, and the medicine in the feeding block 83 is added to the chamber, achieving the effect of adding medicine; S4: After the reagent is added into the chamber, it reacts with the sewage in the chamber. After the reaction, the pump 31 is controlled to operate to send the sewage into the next chamber through the connecting pipe 32. Then, according to the above operation, the connecting rod 86 is pulled to move to add the reagent. This is repeated. After passing through the three chambers on the right, the sewage reacts with the sodium hydroxide, the coagulant and the flocculant in turn, so that the internal oil impurities form flocs. S5: When the liquid pump 31 on the left side is in operation, the sewage and flocs can be transported to the top of the material guide frame 5 through the connecting pipe 32, the flocs are blocked by the filter screen 6, and the sewage passes through the filter screen 6 and enters the leftmost chamber; S6: Connect the connecting wire 43 to electricity, discharge the conductive plate 42, decompose the mineralized residual non-degradable organic matter in the sewage, purify the water quality, make the sewage meet the discharge standard, open the valve at the drain outlet to discharge the purified water, and complete the treatment of sodium phenol sewage.
