Description

Technical Field

[0001] The utility model relates to a water treatment device, more specifically, to a filter material net quick connection device for an oilfield produced water filter. Background Art

[0002] Water flooding has become a key oilfield production method in my country. As water injection into oilfields increases, so does produced water. This produced water is often high in impurities, oil, and corrosive. Direct injection can cause corrosion and blockage in injection pipelines and wellbores. Therefore, it's necessary to implement effective treatment methods for produced water, minimizing its oil and impurity content and ensuring it meets reinjection standards. A filter is a commonly used produced water treatment device. Filters contain filter media. Over time, this media can bind to impurities and crude oil in the produced water, reducing throughput and increasing booster pump outlet pressure. Backwashing filters are necessary. The filter screen prevents filter media loss during backwashing. Over time, dirt clogs the filter screen, reducing backwash effectiveness. This reduces filter throughput and degrades water quality. Injection can cause corrosion and blockage in injection pipelines and wellbores. In this case, the filter screen needs to be disassembled and cleaned frequently. There are four sets of filter screens installed in the filter. The filter screens are fixed by bolts and two flanges are installed in the filter. Due to the small space, half of the body needs to be entered when removing the screws. The screws on the back are difficult to prepare, and disassembly is very difficult. Sometimes it takes more than two hours to remove the sixteen screws. It takes the same amount of time to clean the filter screen and then install it back, which is time-consuming and laborious.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0020] like Figures 1 to 4 As shown, the oilfield produced water filter filter mesh quick connection device includes a fixed clip A and a movable clip B. The fixed clip A is detachably connected to the movable clip B. The fixed clip A is connected to a filter body flange 10, and the movable clip B is connected to a filter mesh 11.

[0021] The fixing buckle A comprises a disc-shaped first flange 1 and a tubular first tube body 2. The first flange 1 is connected to the filter body flange 10. A pair of first L-shaped buckles 3 are provided on the end surface of the first flange 1. Each of the first L-shaped buckles 3 is provided with a limit baffle 4. A plurality of sealing ring grooves 5 are provided on the outer wall of the first tube body 2. A sealing ring 9 is provided in each of the sealing ring grooves 5.

[0022] The movable buckle B includes a disc-shaped second flange 6 and a tubular second tube body 7. The second flange 6 is connected to the filter material net 11. A pair of second L-shaped buckles 8 are provided on the end surface of the second tube body 7. The second L-shaped buckles 8 cooperate with the first L-shaped buckle 3.

[0023] The fixed buckle A and the movable buckle B are both made of stainless steel.

[0024] The working mode of the filter material net quick connection device of the oilfield produced water filter is described below.

[0025] like Figure 5 As shown, the first flange 1 of the fixed clip A to be installed is a DN50 flange, and the dimensions of the first tube 2 are φ60*500mm. The second flange 6 of the movable clip B is also a DN50 flange, and the dimensions of the second tube 7 are φ72*500mm. The dimensions of the sealing ring 9 are 53*3mm.

[0026] First, the first flange 1 of the fixing buckle A and the flange 10 of the filter body are connected with screws to fix the fixing buckle A on the filter body.

[0027] Next, install two 53*3mm sealing rings on the sealing ring groove 5.

[0028] Finally, the second flange 6 of the movable clip B is screwed to the filter screen 11. The second L-shaped clip 8 on the movable clip B and the first L-shaped clip 3 on the fixed clip A are then offset and threaded along the first tube 2 to the bottom. The second L-shaped clip 8 and the first L-shaped clip 3 are then tightly connected clockwise. The stopper 4 acts as a limiter and secures the connection, preventing the second L-shaped clip 8 on the movable flange B and the first L-shaped clip 3 on the fixed clip A from misaligning and loosening. At this point, the two 53*3mm sealing rings installed in the sealing ring groove 5 ensure a tight fit between the first tube 2 and the second tube 7, providing a seal.
