[0002] An oilfield water quality treatment device is designed and functioned mainly around improving the water quality of oilfield water use.

[0003] An oilfield water quality treatment device is a special equipment for treating oilfield water, aiming to remove harmful substances such as impurities, oil stains, sediment, suspended solids, etc. in water, so as to improve water quality and protect pipelines, water supply equipment, water storage equipment and formations from pollution.

[0004] After retrieval, the utility model with the publication number CN217489888U discloses an oilfield water quality treatment device. Although this utility model patent solves the problems that in the filtration process of the existing oilfield water quality treatment device, particulate impurities in the oilfield sewage will accumulate, resulting in the blockage of the internal mesh holes of the device, thus affecting the filtration speed of the sewage and the particulate impurities in the device are not easy to be quickly taken out and the device is not easy to be cleaned; however, this utility model patent has the following problems:

[0005] First, due to the large number of impurities and harmful substances in the oilfield, oilfield water quality treatment not only needs to filter out larger impurities but also requires multiple steps of treatment. This utility model patent can only conduct preliminary filtration on oilfield water quality. After filtration, the oilfield sewage still needs to be transferred to a second treatment tank for secondary treatment, and the transfer process is cumbersome and the treatment efficiency is low.

[0006] Second, this utility model patent uses the swing of the connecting rod to remove the impurities accumulated on the surface of the filter plate. Due to the existence of motion dead angles of the swinging connecting rod, the impurities on the surface of the filter plate are not thoroughly cleaned, and manual secondary treatment is required, so the practicability is low.

[0007] Therefore, an oilfield water quality treatment device is proposed. Utility Model Content

[0008] In view of this, the utility model provides an oilfield water quality treatment device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0009] The technical solution of the utility model is realized as follows: An oilfield water quality treatment device includes an oilfield water quality treatment tank 1.

A pulley 7 is rotatably connected to the outer wall of the support rod 6. A transmission belt 8 is installed on the outer walls of the pulley 7 and the pulley 5. A cleaning rod 9 is fixedly connected to the outer wall of the transmission belt 8. Sliding rods 10 are fixedly connected to both ends of the cleaning rod 9. A chute 11 is opened on the inner wall of the oilfield water quality treatment tank 1. The chute 11 is slidably connected to the outer wall of the sliding rod 10.

[0028] One side of the oilfield water quality treatment tank 1 is communicated with an oilfield water quality treatment tank 12. A motor 13 is fixedly connected to the inner wall of the oilfield water quality treatment tank 12. The output end of the motor 13 is fixedly connected to a stirring blade 14. An air pump 15 is fixedly connected to the bottom of the oilfield water quality treatment tank 1. The suction port of the air pump 15 is communicated with the external environment. The exhaust hole 17 of the air pump 15 is communicated with a T-shaped exhaust pipe 16. Exhaust holes 17 are uniformly opened on the outer wall of the exhaust hole 17. A sewage collection tank 18 is communicated with the outer wall of the oilfield water quality treatment tank 1. The sewage collection tank 18 is located at one end of the filter screen 3. A sewage discharge pipe 19 is communicated with the bottom of the sewage collection tank 18. A water inlet hopper 20 is communicated with the upper surface of the oilfield water quality treatment tank 1. A drainage pipe 21 is communicated with one side of the oilfield water quality treatment tank 1.

[0029] In one embodiment, there are two groups of chutes 11, and the two groups of chutes 11 are symmetrically arranged. The two groups of chutes 11 cooperate with the sliding rod 10, so that the cleaning rod 9 is more stable during the moving process, and the garbage on the surface of the filter screen 3 is cleaned. The filter screen 3 is inclined, and the end of the filter screen 3 close to the sewage collection tank 18 is at a lower position. The filter screen 3 is inclined towards the sewage collection tank 18, so that the sundries accumulated on the upper surface of the filter screen 3 fall into the sewage collection tank 18. A water quality detector 22, an alarm 23 and a controller are fixedly connected inside the oilfield water quality treatment tank 1. The water quality detector 22, the alarm 23 and the controller are electrically connected. The motorized hydraulic rod 2, the motor 4, the motor 13, the air pump 15, the water quality detector 22, the alarm 23 and the controller are respectively electrically connected to an external power supply. The coagulant and the flocculant are selected from the types well-known to those skilled in the art.

[0030] When the utility model works: pour the oilfield sewage to be treated into the first oilfield water quality treatment tank 1 through the water inlet hopper 20. The filter screen 3 preliminarily filters the larger impurities in the oilfield sewage to be treated. Start the first motor 4, and the first motor 4 drives the first pulley 5 to rotate. With the cooperation of the support rod 6 and the second pulley 7, the rotation of the first pulley 5 drives the transmission belt 8 to rotate, and the transmission belt 8 drives the cleaning rod 9 to move. When the cleaning rod 9 passes through the surface of the filter screen 3, the impurities accumulated on the surface of the filter screen 3 are flicked into the sewage collection tank 18. The movement of the cleaning rod 9 drives the sliding rod 10 to move. With the cooperation of the sliding groove 11, the movement of the cleaning rod 9 is more stable during the movement process, and the cleaning effect on the filter screen 3 is better. Start the electric hydraulic rod 2, and the electric hydraulic rod 2 extends to move the filter screen 3 to the bottom of the first oilfield water quality treatment tank 1. Pour an appropriate amount of coagulant and flocculant into the first oilfield water quality treatment tank 1 through the water inlet hopper 20 to aggregate the sewage suspended matter in the first oilfield water quality treatment tank 1. Start the second motor 13, and the second motor 13 drives the stirring blade 14 to rotate, so that the aggregation efficiency is higher. After a period of time, start the electric hydraulic rod 2 to move the filter screen 3 up to the initial position through the electric hydraulic rod 2. Clean the impurities on the surface of the filter screen 3 again by starting the electric hydraulic rod 2 again. Move the filter screen 3 to the bottom of the first oilfield water quality treatment tank 1 again. Start the air pump 15, and pass air into the sewage in the first oilfield water quality treatment tank 1 through the air pump 15. The exhaust holes 17 separate the air into small bubbles, and the small bubbles wrap the smaller impurities, so that the impurities move up. Pour clean water into the first oilfield water quality treatment tank 1 through the water inlet hopper 20, so that the bubbles contact the cleaning rod 9, and the impurities in the bubbles are scraped out by the cleaning rod 9 into the sewage collection tank 18 for centralized treatment. When the water quality detector 22 detects that the water quality in the first oilfield water quality treatment tank 1 meets the standard, the controller controls the alarm 23 to send a signal, and the staff can drain the water through the drain pipe 21. If the water quality is unqualified, repeat the treatment steps until the water quality reaches the discharge standard. There is no need to transfer the oilfield sewage to the second treatment tank for secondary treatment. The treatment efficiency is relatively high, and the impurities on the surface of the filter screen 3 are cleaned relatively thoroughly, without the need for manual secondary treatment, so the practicability is relatively high.
