[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, this utility model discloses a coal-water separation device for drilling rigs, including a base 1. A main separation chamber 2 is located at the upper end of the base 1. A main separation chamber filter element 3 is installed in the middle of the main separation chamber 2. The main separation chamber filter element 3 has a cylindrical separation space. The lower end of the main separation chamber filter element 3 is connected to a mud discharge pipe 5 via a conical connecting seat 4. A mud discharge auger 6 is installed in the mud discharge pipe 5. An inlet connector 7 and an outlet connector 8 are located on the left side of the main separation chamber 2. The liquid inlet connector 7 passes through the main separation chamber 2 and communicates with the bottom of the separation space 1. The liquid outlet connector 8 is communicated with the main separation chamber 2. The separation space 1 is provided with a rotating shaft 9 at the axis position. The rotating shaft 9 is connected to a brush 10 adapted to the inner wall of the filter element 3 of the main separation chamber through a bracket. The bottom of the rotating shaft 9 is connected to a double scraper 11 adapted to the inner wall of the connecting seat 4. The top of the filter element 3 of the main separation chamber is connected to a vibrator 12.

[0027] In a specific embodiment of this application, there are two main separation chamber filter elements 3, i.e., a double filter cartridge design is adopted. The filtration part of the main separation chamber filter element 3 adopts a high-flow stainless steel precision filter screen (with an accuracy of 50-100 microns, which can be replaced according to the site requirements). The mud and water enter the main separation chamber filter element 3 through the liquid inlet connector 7 and the connecting pipe 3 16. Large particles of impurities are separated by the high-frequency vibration filter screen. The clean water flows downstream through the liquid outlet connector 8 and the pipeline. To increase the safety of use, the overflow connector 17 is connected to the upper end of the main separation chamber filter element 3 through the connecting pipe 2 15.

[0028] In one specific embodiment of this application, a brush-type cleaning device is configured inside the main separation box filter element 3, including a rotating shaft 9. The rotating shaft 9 is connected to a brush 10 adapted to the inner wall of the main separation box filter element 3 via a bracket. The rotating shaft 9 is driven by a pneumatic motor with a reducer installed on the top of the main separation box 2 (which can automatically switch between forward and reverse rotation). When the rotating shaft 9 rotates, it drives the brush 10 to brush the inner wall of the main separation box filter element 3. At the same time, combined with the vibration of the main separation box filter element 3, the dirt and impurities that are blocked or attached to the main separation box filter element 3 can be brushed off and shaken off. The dirt and impurities that are brushed off settle on the conical inner wall of the connecting seat 4. When the rotating shaft 9 rotates, it also drives the double scraper 11 to rotate and scrape the conical inner wall of the connecting seat 4, which is conducive to the rapid discharge of dirt and impurities and avoids adsorption and accumulation.

[0029] In one specific embodiment of this application, the sludge discharge pipe 5 and the sludge discharge auger 6 are made of multi-element alloy reinforced materials. Through nano-grain refinement technology, their impact resistance, toughness, and wear resistance are 5 times that of traditional materials, and their service life is 10 times longer than that of ordinary materials. The auger provides strong extrusion, efficient dehydration, and reduces waste volume, producing waste residue with low moisture content, significantly reducing treatment costs.

[0030] In a specific embodiment of this application, when the main separation box filter element 3 continues to operate, the sludge concentration in the filter screen will increase, threatening the downstream water quality. The system automatically triggers the pneumatic diaphragm pump 18, which runs according to the set time to discharge the high-concentration sludge into the external sedimentation tank for sedimentation. Furthermore, this equipment can be equipped with a secondary vibration separation device, including a secondary separation box 20, a secondary vibration box filter element 21, a second sludge discharge pipe 22, a second sludge discharge auger 23, and a second vibrator 24. Its working principle is similar to that of the main separation box 2. At the same time, the secondary vibration separation device is equipped with a return pipe 30 to prevent the secondary vibration box filter element 21 from becoming clogged.

[0031] In a specific embodiment of this application, a rubber sealing ring 1 is provided at the connection between connecting pipe 13 and the main separation box filter element 3, a rubber sealing ring 2 is provided at the connection between connecting pipe 2 15 and the main separation box filter element 3, a rubber sealing ring 3 is provided at the connection between connecting pipe 3 16 and the main separation box filter element 3, a rubber sealing ring 4 is provided at the connection between connecting pipe 4 19 and the main separation box filter element 3, and a rubber sealing ring 5 31 is provided at the connection between the main separation box filter element 3 and the connecting seat 4. The rubber sealing rings serve two purposes: firstly, to seal the connection, and secondly, to provide a soft connection against the vibration of the main separation box filter element.

[0032] In one specific embodiment of this application, a spray pipe 28 is provided at the bottom of the main separation box 2, through which water can enter via a spray connector 27. When the equipment is stopped or under maintenance, a one-button cleaning function can be realized, and the water is discharged through a drain connector 29 after cleaning.

[0033] In a specific embodiment of this application, a switch valve is installed at each pipe joint. The switch valve is connected to a controller installed on the main separation box 2 to control the switch valve. At the same time, the motor driving the auger, the motor driving the rotating shaft, the pneumatic diaphragm pump and other components are all connected to the controller, thereby realizing the intelligent operation of the equipment under the control of the controller.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
