Description

Technical Field

[0001] This utility model relates to the field of rock cuttings treatment technology, and in particular to a water filtration device for oil-based rock cuttings treatment. Background Technology

[0002] Oil-based cuttings are a key material in horizontal drilling technology during shale gas development. Different formulations are used to formulate oil-based cuttings according to different geological conditions, resulting in cuttings containing large amounts of mineral oil and high molecular weight compounds. Water filtration devices for oil-based cuttings treatment refer to physical filtration equipment specifically designed to treat oily wastewater generated during the washing, thermal desorption, and centrifugal separation processes of oil-based cuttings. Their core task is to efficiently remove suspended solids (rock cuttings powder, clay, etc.) and residual oil (free oil, emulsified oil) from the water through multi-stage filtration technology, ensuring the effluent meets reuse standards (such as for preparing drilling fluids) or complies with discharge requirements.

[0003] In existing water filtration devices for oil-based rock treatment, the internal filter media can only be replaced by stopping the filtration process. This method of stopping the machine for replacement reduces the effectiveness of the device.

[0004] Therefore, it is necessary to provide a new water filtration device for oil-based rock cuttings treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water filtration device for oil-based rock cuttings treatment.

[0006] The oil-based rock cuttings treatment water filtration device provided by this utility model includes: a base plate, wherein a treatment pool for filtering the treated water is provided on the base plate;

[0007] The treatment tank is fixedly installed with multiple partition plates, which can divide the interior of the treatment tank into multiple independent compartments. Each independent compartment is equipped with a fixedly connected pad frame, and a filter plate is installed on the pad frame. Filter media is placed on top of the filter plate in each independent compartment.

[0008] A fixed water inlet pipe is installed in the center of the treatment tank. The water inlet pipe has a three-way structure. The water inlet end of the water inlet pipe is located outside the treatment tank. The remaining two branch pipes of the water inlet pipe are respectively connected to two independent compartments in the center of the treatment tank, and each independent branch pipe is equipped with a valve.

[0009] The treatment pool has two independent compartments at the center connected by water pipes to the corresponding independent compartments on both sides, and each independent compartment is equipped with a liquid level sensor on top.

[0010] Preferably, the ends of the two branch pipes and the guide pipe in the water inlet pipe are provided with water inlet components, and the water inlet components include connecting pipes, and the connecting pipes are connected to the ends of the two branch pipes and the guide pipes in the corresponding water inlet pipes.

[0011] Preferably, a rotating rod is inserted inside the connecting tube, and one end of the rotating rod extends to the outside of the connecting tube and is fixedly installed with multiple evenly distributed mixing blades in a light-proof manner.

[0012] Preferably, a plurality of evenly distributed blades are fixedly installed on the outer wall of the rotating rod in the area inside the connecting tube, and the outer wall of the blades abuts against and slides in connection with the inner wall of the connecting tube.

[0013] Preferably, each of the independent compartments on both sides of the treatment pool is fixedly equipped with a connected drain pipe, and each of the independent compartments located in the center of the treatment pool is fixedly equipped with a connected drain pipe. Furthermore, each independent compartment in the treatment pool is provided with a fixedly connected sealing cover.

[0014] Preferably, the filter plates and filter media located at the center and on both sides of the treatment tank have different specifications.

[0015] Compared with related technologies, the oil-based rock cuttings treatment water filtration device provided by this utility model has the following beneficial effects:

[0016] 1. This utility model divides the treatment tank into multiple independent spaces by installing a partition plate inside the treatment tank. A three-way water inlet pipe is inserted inside the treatment tank. In later use, sewage can be injected into one side of the treatment tank through a branch pipe on one side of the water inlet pipe. When the filter media on one side becomes clogged, the branch pipe on the other side of the water inlet pipe can be opened to inject water into the other side of the treatment tank. This allows the staff to continuously treat sewage while replacing the filter media.

[0017] 2. Through the setting of the water inlet component, the flowing water source can drive the blades in the connecting pipe during the injection and diversion of sewage, so that the blades drive the rotating rod and the external mixing blades to rotate. The rotating mixing blades can stir and mix the water source in the corresponding area, so that the sewage can flow into the filter media in the corresponding part in a more dispersed and uniform state, thereby enabling the filter media to filter the sewage more evenly.

[0018] 3. By setting the initial injection of sewage to an upward injection method, the particles in the sewage can automatically settle downward under the action of gravity during the initial filtration of sewage, reducing the phenomenon of particles falling into the filter media and causing rapid clogging of the filter media, thereby improving the service life of the filter media.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 The present invention provides an oil-based rock cuttings treatment water filtration device, which includes a base plate 1.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 5The base plate 1 is equipped with a treatment tank 2 for filtering the treated water. Multiple partition plates 21 are fixedly installed inside the treatment tank 2, which can divide the interior of the treatment tank 2 into multiple independent compartments. Each independent compartment is equipped with a fixedly connected pad frame 24, and a filter plate 3 is installed on the pad frame 24. Filter media is placed on the top of the filter plate 3 in each independent compartment. A fixedly connected water inlet pipe 4 is installed in the center of the interior of the treatment tank 2. The water inlet pipe 4 has a three-way structure, with the water inlet end of the water inlet pipe 4 located outside the treatment tank 2. The remaining two branch pipes of the water inlet pipe 4 are respectively connected to the two independent compartments in the center of the treatment tank 2, and each independent branch pipe is equipped with a valve. Water guide pipes 5 are fixedly installed between the two independent compartments in the center of the treatment tank 2 and the corresponding independent compartments on both sides. Liquid level sensors 22 are installed on the top of each independent compartment.

[0029] It should be noted that by installing a partition plate 21 inside the treatment tank 2, the interior of the treatment tank 2 can be divided into multiple independent spaces. A three-way water inlet pipe 4 is inserted inside the treatment tank 2. In later use, sewage can be injected into one side of the treatment tank 2 through a branch pipe on one side of the water inlet pipe 4. When the filter media on one side becomes clogged, the branch pipe on the other side of the water inlet pipe 4 can be opened to inject water into the other side of the treatment tank 2. This allows the staff to continuously treat sewage while replacing the filter media.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 Water inlet assembly 6 is provided at the ends of the two branch pipes and the water guide pipe 5 in the water inlet pipe 4. The water inlet assembly 6 includes a connecting pipe 61, and the connecting pipe 61 is connected to the ends of the two branch pipes and the water guide pipe 5 in the corresponding water inlet pipe 4. A rotating rod 62 is inserted inside the connecting pipe 61 and is rotatably connected. One end of the rotating rod 62 extends to the outside of the connecting pipe 61 and is fixedly installed with multiple evenly distributed mixing blades 63 in a light-proof manner. Multiple evenly distributed blades 621 are fixedly installed in the area of ​​the outer wall of the rotating rod 62 inside the connecting pipe 61, and the outer wall of the blades 621 abuts against and slides against the inner wall of the connecting pipe 61.

[0031] It should be noted that: through the setting of the water inlet component 6, during the injection and diversion of sewage, the flowing water source can drive the blades 621 in the connecting pipe 61, so that the blades 621 drive the rotating rod 62 and the external mixing blades 63 to rotate. The rotating mixing blades 63 can stir and mix the water source in the corresponding area, so that the sewage can flow into the filter media in the corresponding part in a more dispersed and uniform state, thereby enabling the filter media to filter the sewage more evenly.

[0032] In an optional embodiment: To prevent the blades 621 from becoming stuck due to insufficient water flow impact force in the water guide pipe 5 or small particles adhering to the blades 621 during use, thus preventing the blades 621 from driving the mixing blades 63, a flow meter for monitoring the internal water flow velocity can be installed on the water guide pipe 5, and a motor for driving the rotating rod 62 can be installed on the connecting pipe 61. Both the flow meter and the motor have an IP68 waterproof rating. During use, when the terminal controller detects that the flow velocity in the corresponding water guide pipe 5 is less than the set value through the flow meter, it can control the motor to drive the rotating rod 62 and the blades 621 to rotate, so that the blades 621 can always drive the mixing blades 63 to rotate, thus avoiding the phenomenon that the blades 621 cannot drive the mixing blades 63.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 5 Each of the independent compartments on both sides of the treatment pool 2 is fixedly equipped with a connected drain pipe 26, and each of the independent compartments located in the center of the treatment pool 2 is fixedly equipped with a connected drain pipe 25. Each independent compartment in the treatment pool 2 is also equipped with a fixedly connected sealing cover 23.

[0034] It should be noted that: with the setting of the drain pipe 26, after the filtered water flows down to the bottom of the corresponding independent compartment, the water can be discharged out through the drain pipe 26. With the setting of the drain pipe 25, when it is necessary to clean the filter media in the independent compartment, the corresponding drain pipe 25 can be opened, so as to facilitate the discharge and cleaning of the water in the compartment.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 5 The filter plates 3 and filter media located in the center and on both sides of the treatment tank 2 have different specifications.

[0036] It should be noted that by setting filter plates 3 and filter media of different specifications, dual filtration of coarse and fine filtration of water source can be achieved, thereby helping to improve the filtration effect of this device.

[0037] The working principle of the oil-based rock cuttings treatment water filtration device provided by this utility model is as follows:

[0038] When using this device, the operator can first fix the filter plate 3 in the corresponding independent compartment in the treatment tank 2, then place the different filter media in the corresponding compartments and install the sealing cover 23.

[0039] Then the valve on one side of the branch pipe in the inlet pipe 4 can be opened. At this time, the water for treating oil-based rock cuttings can flow into the inside of the treatment tank 2 through the inlet pipe 4. During this process, the flowing water will first enter the connecting pipe 61 in the corresponding inlet component 6. The water entering the connecting pipe 61 will drive the blade 621 outside the rotating rod 62. Thus, the blade 621 can drive the rotating rod 62 and its external mixing blade 63 to rotate. The water passing through the blade 621 will flow into the corresponding independent compartment of the treatment tank 2 through the end of the connecting pipe 61.

[0040] During this process, the rotating mixing blade 63 stirs and mixes the water in the independent compartment, allowing the water to permeate upwards in a more uniform state. The corresponding filter media can then perform preliminary filtration of the water permeating from bottom to top. During this process, relatively large particles in the water can accumulate inside the corresponding independent compartment under the action of gravity, thereby reducing the speed at which particles clog the corresponding filter media and extending the service life of the filter media that performs preliminary filtration of the water.

[0041] After initial filtration, the water source can flow through the water pipe 5 to the independent compartment located at the edge of the treatment tank 2. The water source entering the water pipe 5 can also be mixed a second time, so that the water source can be more evenly diffused outward for secondary filtration.

[0042] During the filtration process, when the filter media inside the corresponding independent chamber becomes clogged, the water flow will accumulate in the independent chamber. When the accumulated water rises to the level sensor 22, the terminal controller can open the valve on the other side of the branch pipe in the inlet pipe 4 and close the valve on the corresponding branch pipe by detecting the level sensor 22. This allows the water to be injected into the other side of the treatment tank 2 for filtration. During this process, the staff can replace the clogged filter media, thus achieving uninterrupted water supply.

[0043] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0044] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
