DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 -- Figure 4 As shown, this specific implementation adopts the following technical solution: it includes:

[0026] The still box 1 is a hollow box-type structure. A still water port 2 is provided on the top of the still box 1. A drain port 3 is provided on the right side wall of the still box 1. The still box 1 allows the sewage from the oil well to have enough reaction time with the reactant to condense the oil and other substances in the sewage into blocks. A cleaning plate 17 is provided in the middle of the top surface of the still box 1, so that the operator can open the cleaning plate 17 later to clean the still box 1.

[0027] The drainage component 4 is arranged at the drainage port 3, the filter plate 5 is arranged on the right side of the drainage port 3, and the filter plate 5 is connected to the drainage component 4. The filter plate 5 and the drainage component 4 are used together to facilitate filtering the sewage in the clean water tank. The drainage component 4 includes:

[0028] A limit frame 11 is fixedly arranged on the right side surface of the static box 1, and the limit frame 11 is arranged at the opening of the drain port 3. The inner walls of the limit frame 11 on both sides are provided with card slots 12. The front and rear sides of the filter plate 5 are movably inserted into the card slots 12. The limit frame 11 plays a role in positioning the filter plate 5, which is convenient for operators to install and remove the filter plate 5, thereby cleaning the debris on the filter plate 5. A limit plate 16 is arranged on the right end of the filter plate 5, and the limit plate 16 movably contacts the limit frame 11 to prevent sewage from leaking out of the limit frame 11;

[0029] The electric push rod 13 is fixedly arranged on the static box 1, and a baffle 14 is arranged at the output end of the electric push rod 13, and the baffle 14 is movably inserted in the drain port 3. The electric push rod 13 is connected to an external power supply, and the position of the baffle 14 is controlled by the electric push rod 13, thereby controlling the closing of the drain port 3, so as to facilitate the sewage in the static box 1 to pass through the drain port 3;

[0030] A water level detector 15, wherein the water level detector 15 is arranged on the inner wall of the pressure box 6, and the electric push rod 13 is electrically connected to the water level detector 15, so as to control the time when the baffle 14 opens the drain port 3;

[0031] The pressure box 6 is a box-type structure with upper and lower openings. The pressure box 6 is arranged above the static box 1, and the bottom end of the pressure box 6 is connected to the static water port 2. The top of the pressure box 6 is provided with a groove 7. The water inlet pipe 8 is arranged on the pressure box 6. The water level difference in the pressure box 6 is used to squeeze the sewage in the static box 1 out from the drain port 3.

[0032] The arc filter plate 9 is movably arranged in the groove 7, and the bottom surface of the arc filter plate 9 is movably arranged to contact with the inner wall of the groove 7. The outlet of the water inlet pipe 8 is located above the arc filter plate 9. The arc filter plate 9 is convenient for filtering sewage and debris in the water inlet pipe 8. A plurality of water retaining plates 18 are arranged in the arc filter plate 9 to prevent sewage from flowing out of the pressure box 6 from the arc filter plate 9.

[0033] An electric push rod 10 is fixedly arranged on the left side surface of the pressure box 6, and the output end of the electric push rod 10 is connected to the front end of the arc filter plate 9. The electric push rod 10 is connected to an external power supply. The electric push rod 10 is used to push the arc filter plate 9 to move in the groove 7, so as to facilitate the adjustment of the position of the arc filter plate 9, thereby facilitating the operator to clean the arc filter plate 9.

[0034] When using the utility model, the operator first discharges the oil well sewage through the water inlet pipe 8 to the arc filter plate 9 through an external water pump, and utilizes the filtering effect of the arc filter plate 9 to filter the floating debris in the oil well sewage, so that the oil well sewage enters the static box 1 through the pressure box 6, and allows the oil well sewage to stand in the static box 1 for a period of time to fully react with the reactant to form a coagulant. When the water level in the pressure box 6 reaches a certain height, the electric push rod 13 is opened through the water level detector 15, and the electric push rod 13 drives the baffle 14 to move in the drain port 3 to open the drain port 3. By utilizing the water level difference, the oil well sewage in the static box 1 enters the limit frame 11 through the drain port 3, and the coagulant in the sewage is separated by filtering the filter plate 5. After a period of time, the electric push rod 13 will drive the baffle 14 to descend, and the drain port 3 is closed. The operator pulls out the filter plate 5 from the card slot 12 to clean the coagulant on the filter plate 5.

[0035] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0036] 1. Set up a static box 1 and a pressure box 6. Use the static box 1 to allow the oil well sewage to remain static for a period of time, so that the oil well sewage and the reactant can be fully mixed and reacted. Then, use the water level difference in the pressure box 6 to discharge the sewage in the static box 1 from the drain port 3;

[0037] 2. Set up a water discharge assembly 4, and control the opening time of the electric push rod 13 through a water level sensor. At the same time, use the limit frame 11 to facilitate the removal of the filter plate 5, so that the operator can clean the debris on the filter plate 5.
