[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, the pollutant collection device for the oil field well site includes a box body 1, a centrifugal cylinder 4, a filter screen 7 and a filter grille 5. The box body 1 is provided with a water inlet pipe 17 facing the cylinder mouth of the centrifugal cylinder 4, and a mounting cover 9 for rotatably mounting the centrifugal cylinder 4 is fixedly connected in the box body 1. The bottom surface of the mounting cover 9 is inclined, and a connecting pipe 15 is connected to the lowest point of the side of the mounting cover 9. The connecting pipe 15 leads to the filter grille 5, and a flow meter 16 is arranged in the connecting pipe 15. The filter grille 5 is tilted in the box body 1, and a drain pipe 8 is arranged on the filter grille 5. The drain pipe 8 and the water inlet pipe 17 are both provided with flow meters 16.

[0024] Specifically, the sewage enters the centrifugal drum 4 along the water inlet pipe 17, and is filtered under the high-speed rotation of the centrifugal drum 4. The filtered sewage flows along the connecting pipe 15 of the installation cover 9 to the filter grille 5 for secondary filtration, and the sewage that has been secondary filtered by the filter grille 5 flows out along the drain pipe 8. In addition, by arranging a flow meter 16 in the connecting pipe 15 and the drain pipe 8, the water flow rate can be detected in real time, and the permeability of the centrifugal drum 4 and the filter grille 5 can be judged by detecting the water flow rate. When the centrifugal drum 4 is clogged with more debris, the filtration speed slows down, so the water flow rate detected by the flow meter 16 in the connecting pipe 15 will also decrease. Similarly, when the filter grille 5 is clogged with more debris, the filtration speed slows down, so the water flow rate detected by the flow meter 16 in the drain pipe 8 will also decrease, which is convenient for personnel to judge whether the centrifugal drum 4 and the filter grille 5 need to be cleaned according to the flow rate detected by the flow meter 16.

[0025] In addition, a weighing device 6 is fixedly connected to the box body 1 , a hanging block 10 is fixedly connected to the hanging rod of the weighing device 6 , and a clamping block 12 for plugging with the cylinder mouth of the filter screen 7 is plugged into the hanging block 10 .

[0026] The curvature of the clamping block 12 is equal to that of the filter screen 7 , and an electric push rod 11 is provided between the clamping block 12 and the hanging block 10 .

[0027] A plurality of insert blocks 14 are fixedly connected to the outer bottom surface of the filter screen 7 , and an insert cylinder 13 sleeved with the insert blocks 14 is fixedly connected to the bottom of the centrifugal cylinder 4 .

[0028] Specifically, by plugging the plug block 14 into the plug tube 13, the centrifugal tube 4 can smoothly drive the filter screen 7 to rotate, thereby realizing rapid screening of sewage under the action of centrifugal force. The clamping block 12 is clamped on the surface of the filter screen 7 to ensure that the filter screen 7 can rotate smoothly. At the same time, by plugging the clamping block 12 into the lifting block 10, it is convenient to measure the weight of the filter screen 7 in real time through the weighing device 6, so as to facilitate personnel to regularly assist in judging the weight of the filtered material collected in the filter screen 7, and to facilitate personnel to judge the weight of the filtered material in the filter screen 7 according to the numerical value of the weighing device 6, so as to help personnel judge whether the filter screen 7 needs to be cleaned. Moreover, by contracting the electric push rod 11, the clamping block 12 is separated from the filter screen 7, so that personnel can take out the filter screen 7 for cleaning.

[0029] In addition, the outer wall of the box body 1 is rotatably connected to a mounting frame 2, and the mounting frame 2 is fixedly connected to a motor 3 for driving the box body 1 to rotate.

[0030] Specifically, the box body 1 is driven to rotate by the motor 3 on the mounting frame 2. When the mounting frame 2 is fixed, the box body 1 is rotated, thereby realizing the dumping of the filtered material in the filter screen 7 and the filter grid 5.

[0031] In addition, a motor 3 is also arranged at the bottom of the box body 1 , and the main shaft of the motor 3 in the box body 1 passes through the bottom of the mounting cover 9 and is fixedly connected to the bottom of the centrifugal cylinder 4 .

[0032] The outer bottom of the centrifugal cylinder 4 is rotatably connected to the inclined bottom of the mounting cover 9.

[0033] Working principle: sewage enters the centrifugal drum 4 along the water inlet pipe 17, and under the driving action of the motor 3 in the box body 1, the centrifugal drum 4 drives the filter screen 7 to rotate, so as to realize the primary filtration of sewage. The filtered sewage flows along the inclined cover bottom of the mounting cover 9 to the connecting pipe 15, and then enters the filter grille 5 along the connecting pipe 15 for secondary filtration. The water after secondary filtration is discharged along the drain pipe 8. The personnel judge the degree of blockage of the filter screen 7 and the filter grille 5 by detecting the readings of the flow meter 16 in the connecting pipe 15 and the drain pipe 8. When cleaning the filter screen 7 and the filter grille 5, the motor 3 on the mounting frame 2 drives the box body 1 to rotate, so that the filtered material in the filter screen 7 and the filter grille 5 can be dumped.

[0034] The wiring diagram of the motor 3, the electric push rod 11 of the weighing device 6 and the flow meter 16 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the motor 3, the electric push rod 11 of the weighing device 6 and the flow meter 16 are no longer explained in detail.
