Description

Technical Field

[0001] This invention relates to the field of drilling wastewater treatment devices, and more particularly to a filtration and treatment device for drilling wastewater. Background Technology

[0002] During oil and gas drilling operations, a large amount of drilling wastewater is generated. This wastewater is mixed with solid impurities such as drill cuttings, mud, and clay particles, as well as residues of various drilling additives. Direct discharge of this wastewater will cause soil and water pollution and does not meet environmental protection discharge requirements. Therefore, the filtration and treatment of drilling wastewater is a key process in drilling operations.

[0003] Traditional drilling wastewater filtration equipment often uses a single filter layer, resulting in limited filtration precision and difficulty in completely removing fine impurities. Furthermore, the filter media is prone to clogging, requiring frequent shutdowns for cleaning, which severely impacts treatment efficiency. Additionally, traditional equipment lacks effective agitation and clarification mechanisms, causing sediment in the wastewater to accumulate at the bottom of the tank. This not only reduces filtration effectiveness but also increases equipment maintenance difficulty, making it difficult to meet the continuous processing needs of large-scale drilling operations. Moreover, the functional modules of traditional filtration equipment often operate independently, lacking a coordinated design. Wastewater filtration often requires additional secondary treatment processes, which are cumbersome and energy-intensive. While some equipment may have multi-stage filtration capabilities, their unreasonable structural design and poor connection between filtration and slag discharge can easily lead to impurity backflow, resulting in treated water quality failing to meet standards. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drilling wastewater filtration and treatment device. This device is a specialized treatment equipment with multi-stage filtration, automatic unclogging, and modular linkage functions to meet the environmental protection requirements of modern drilling operations and achieve efficient wastewater purification and convenient maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A filtration and treatment device for drilling wastewater includes a holding mechanism, a sifting mechanism on the upper side of the holding mechanism, an agitation mechanism fixedly connected to the lower middle part of the sifting mechanism, a filter screen mechanism on the right side of the holding mechanism, and a linkage mechanism on the rear side of the holding mechanism. The container includes a box, a filter plate fixedly connected to the upper inner wall of the box, and a strip groove through the middle of the filter plate. Sliding grooves are provided through the upper ends of both the left and right sides of the box. A heightening strip is fixedly connected to the top left side of the box, and an extension guide plate is fixedly connected to the top right side of the box. Furthermore, the clearing mechanism includes a dual-head motor fixedly connected to the rear left side of the upper end of the housing, a threaded rod fixedly connected to the output end of the front side of the dual-head motor, and a slide rod fixedly connected to the upper right side of the housing. The threaded rod is rotatably connected to the upper left side of the housing, and a movable frame is threadedly connected to the outer wall of the threaded rod. A slide frame is slidably connected to the upper part of the movable frame. Furthermore, a fixing strip is fixedly connected to the middle of the movable frame, and a hanging plate is fixedly connected to the lower middle of the fixing strip. The hanging plate is disposed on the upper side of the filter plate, and a rack is fixedly connected to the lower side of the hanging plate. A gear is meshed with one side of the rack. Furthermore, the agitation mechanism includes a fixed frame fixedly connected to the lower side of the middle of the movable frame, a rotating rod rotatably connected to the middle of the fixed frame, and a plurality of agitators uniformly fixedly connected to the outer wall of the rotating rod. A second gear is fixedly connected to the upper end of the rotating rod, and a second rack is fixedly connected to the inner wall of the middle of the upper section of the housing. The second rack meshes with the second gear, and a first gear is fixedly connected to the upper side of the second gear. Furthermore, the linkage mechanism includes a pulley one fixedly connected to the output end of the dual-head motor, a rotating shaft rotatably connected to the rear left side of the housing, and a pulley two fixedly connected to the outer wall of the rotating shaft. The middle outer wall of the pulley one and the middle outer wall of the pulley two are connected by a synchronous belt. A bevel gear one is fixedly connected to the end of the rotating shaft away from the housing, and a bevel gear two is meshed with one side of the bevel gear one. Furthermore, the filter screen mechanism includes a frame set on the right side of the box, a trough fixedly connected to the upper inner wall of the front section of the frame, and a drain outlet opened through the middle of the lower side of the trough. Multiple rotating wheels are evenly rotatably connected to the upper side of the front section of the frame, and the same filter screen frame is set on the upper side of each of the multiple rotating wheels. A connecting strip is fixedly connected to the middle of the rear side of the filter screen frame. Furthermore, the end of the connecting strip away from the filter screen frame is rotatably connected to an adapter strip, and the end of the adapter strip away from the connecting strip is fixedly connected to a shaft. Two loading components are fixedly connected to the upper left side of the rear section of the frame. The shaft is rotatably connected to the middle of the two loading components. The end of the shaft away from the adapter strip is fixedly connected to the end of the bevel tooth near the shaft. The upper left side of the filter screen frame is in contact with the lower side of the extension guide plate. Furthermore, a drain pipe is fixedly connected to the lower front side of the box body, and the drain pipe is connected to the interior of the box body.

[0006] The present invention has the following beneficial effects: In this invention, the combination of a holding mechanism, a clearing mechanism, and an agitation mechanism alleviates the problems of traditional drilling wastewater filtration equipment, which often uses a single filter layer, resulting in limited filtration accuracy, difficulty in completely removing fine impurities, and easy clogging of the filter media, requiring frequent shutdowns for cleaning, which seriously affects treatment efficiency. At the same time, traditional equipment lacks an effective agitation and clearing structure, causing sediment in the wastewater to accumulate at the bottom of the tank, which not only reduces the filtration effect but also increases the difficulty of equipment maintenance, making it difficult to meet the continuous treatment needs of large-scale drilling operations.

[0007] In this invention, the linkage mechanism and the filter screen mechanism work together to alleviate the problems of traditional filtration equipment where each functional module operates independently and lacks linkage design. After the sewage is filtered, an additional secondary treatment process is often required, which is cumbersome and energy-intensive. Although some equipment has multi-stage filtration function, the structural design is unreasonable, the connection between filtration and sludge discharge is not smooth, and impurities are prone to backflow, which makes it difficult for the treated water quality to meet the standards.

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] Reference Figure 1-8 An embodiment of the present invention provides a filtration and treatment device for drilling wastewater, comprising a holding mechanism 1, a clearing mechanism 2 disposed on the upper side of the holding mechanism 1, an agitation mechanism 3 fixedly connected to the lower middle part of the clearing mechanism 2, a filter screen mechanism 5 disposed on the right side of the holding mechanism 1, and a linkage mechanism 4 disposed on the rear side of the holding mechanism 1. The holding mechanism 1 includes a box 11, a filter plate 12 fixedly connected to the upper inner wall of the box 11, and a strip groove 13 that runs through the middle of the filter plate 12. Sliding grooves 14 are provided through the upper ends of both the left and right sides of the box 11. A raising strip 15 is fixedly connected to the top left side of the box 11, and an extension guide plate 16 is fixedly connected to the top right side of the box 11. When the equipment is started, the drilling sewage is introduced into the box 11 of the holding mechanism 1. The sewage first passes through the filter plate 12 at the top of the box 11 to complete the primary filtration. The filter plate 12 intercepts the larger solid impurities in the sewage. The filtered sewage falls through the filter plate 12 into the lower part of the box 11 and can be initially discharged through the drain pipe 17.

[0012] The cleaning mechanism 2 includes a dual-head motor 21 fixedly connected to the rear left side of the upper end of the housing 11, a threaded rod 22 fixedly connected to the front output end of the dual-head motor 21, and a slide rod 23 fixedly connected to the upper right side of the housing 11. The threaded rod 22 is rotatably connected to the upper left side of the housing 11. A movable frame 24 is threadedly connected to the outer wall of the threaded rod 22. A slide frame 25 is slidably connected to the upper part of the movable frame 24. When the dual-head motor 21 is started, its front output end drives the threaded rod 22 to rotate. The threaded rod 22 drives the movable frame 24, which is threadedly connected to the outer wall, to slide back and forth along the slide rod 23. The fixing strip 26 in the middle of the movable frame 24 drives the hanging plate 27 to move synchronously on the upper side of the filter plate 12, which facilitates subsequent comprehensive cleaning.

[0013] A fixing strip 26 is fixedly connected to the middle of the movable frame 24. A hanging plate 27 is fixedly connected to the lower middle of the fixing strip 26. The hanging plate 27 is set on the upper side of the filter plate 12. A rack 28 is fixedly connected to the lower side of the hanging plate 27. A gear 29 is meshed on one side of the rack 28. The gear 29 on the upper side of the gear 24 meshes with the rack 28 on the lower side of the hanging plate 27, so that the fixing strip 26 drives the hanging plate 27 to slide back and forth on the upper part of the movable frame 24 according to the sliding frame 25. This allows the hanging plate 27 to scrape and clean the impurities trapped on the surface of the filter plate 12, preventing the filter holes of the filter plate 12 from being blocked. The scraped impurities move with the hanging plate 27 to the extension guide plate 16 and slide into the filter frame 55 of the filter screen mechanism 5 through the extension guide plate 16.

[0014] The agitation mechanism 3 includes a fixed frame 31 fixedly connected to the lower side of the middle of the movable frame 24, a rotating rod 32 rotatably connected to the middle of the fixed frame 31, and multiple agitators 33 uniformly fixedly connected to the outer wall of the rotating rod 32. A gear 2 34 is fixedly connected to the upper end of the rotating rod 32, and a rack 2 35 is fixedly connected to the inner wall of the upper middle section of the housing 11. The rack 2 35 meshes with the gear 2 34. A gear 1 29 is fixedly connected to the upper side of the gear 2 34. During the sliding process of the movable frame 24, the fixed frame 31 on its lower side drives the rotating rod 32 to move synchronously in the strip groove 13 of the filter plate 12. The gear 2 34 at the upper end of the rotating rod 32 meshes with the rack 2 35 on the inner wall of the housing 11. The meshing action drives the rotating rod 32 to rotate, and the multiple agitators 33 on the outer wall of the rotating rod 32 rotate accordingly, agitating the sewage at the bottom of the housing 11 to prevent fine sediments in the sewage from accumulating at the bottom of the housing 11 and to ensure the uniformity of sewage filtration.

[0015] The linkage mechanism 4 includes a pulley 41 fixedly connected to the output end of the dual-head motor 21, a rotating shaft 42 rotatably connected to the rear left side of the housing 11, and a pulley 43 fixedly connected to the outer wall of the rotating shaft 42. The outer wall of the middle part of the pulley 41 and the outer wall of the middle part of the pulley 43 are connected by a synchronous belt 44. A bevel tooth 45 is fixedly connected to the end of the rotating shaft 42 away from the housing 11, and a bevel tooth 46 is meshed on one side of the bevel tooth 45.

[0016] The filter screen mechanism 5 includes a frame 51 located on the right side of the housing 11, a trough 52 fixedly connected to the upper inner wall of the front section of the frame 51, and a drain outlet 53 that penetrates the middle of the lower side of the trough 52. Multiple rotating wheels 54 are evenly rotatably connected to the upper front section of the frame 51. The same filter screen frame 55 is provided on the upper side of each of the multiple rotating wheels 54. A connecting strip 56 is fixedly connected to the middle of the rear side of the filter screen frame 55.

[0017] A connecting strip 57 is rotatably connected to the end of the connecting strip 56 away from the filter screen frame 55. A shaft 59 is fixedly connected to the end of the connecting strip 57 away from the connecting strip 56. Two loading components 58 are fixedly connected to the upper left side of the rear section of the frame 51. The shaft 59 is rotatably connected to the middle of the two loading components 58. The end of the shaft 59 away from the connecting strip 57 is fixedly connected to the end of the bevel gear 46 near the shaft 59. The upper left side of the filter screen frame 55 is in contact with the lower side of the extension guide plate 16. When the dual-head motor 21 is running, its rear output end drives the pulley 41 to rotate. The pulley 41 drives the pulley 43 and the shaft 42 to rotate via the synchronous belt 44. The bevel teeth 45 and 46 at the end of the shaft 42 mesh with each other, thereby driving the shaft 59 to rotate between the two loading components 58. The shaft 59 drives the filter screen frame 55 to reciprocate on the rotating wheel 54 via the adapter bar 57 and the connecting bar 56. The primary impurities are intercepted by sliding from the extension guide plate 16 into the filter screen frame 55. The secondary fine screening is completed with the swing of the filter screen frame 55. The mesh size of the filter screen frame 55 is smaller than that of the filter plate 12, which can further separate the sewage entrained in the impurities.

[0018] A drain pipe 17 is fixedly connected to the lower front side of the box 11. The drain pipe 17 is connected to the interior of the box 11. The mesh size of the filter screen frame 55 is smaller than the filter hole size of the filter plate 12. The wastewater after secondary filtration falls into the trough 52 on the frame 51 and is discharged through the drain outlet 53. The solid impurities trapped in the filter screen frame 55 are collected by swinging, which is convenient for subsequent unified cleaning.

[0019] Gear 2 34 is located on the upper side of filter plate 12, rotating rod 32 is located in the middle of strip groove 13, rack 1 28 has a height corresponding to the height of two sliding grooves 14, and rack 1 28 is located in the middle of two sliding grooves 14.

[0020] Working Principle: The drilling wastewater filtration and treatment equipment of this invention uses a dual-head motor 21 as a single power source to achieve full modular linkage of the sifting mechanism 2, agitation mechanism 3, linkage mechanism 4, and filter screen mechanism 5. Wastewater is collected and initially filtered through the holding mechanism 1. Combined with a multi-stage treatment process including agitation to prevent accumulation, sifting to prevent clogging, and secondary fine screening, efficient purification of drilling wastewater is achieved. All components operate in synergy, and the processes are seamlessly connected. When the equipment starts, the drilling wastewater is introduced into the box 11 of the holding mechanism 1. The wastewater first undergoes primary filtration through the filter plate 12 at the top of the box 11. The filter plate 12 intercepts larger solid impurities in the wastewater. The filtered wastewater passes through the filter plate 12 and falls into the lower part of the box 11, where it can be initially discharged through the drain pipe 17. Simultaneously, the dual-head motor 21 is started. 1. The front output end drives the threaded rod 22 to rotate. The threaded rod 22 drives the movable frame 24, which is connected to the outer wall by threads, to slide back and forth along the slide rod 23. The fixed strip 26 in the middle of the movable frame 24 drives the hanging plate 27 to move synchronously on the upper side of the filter plate 12, which facilitates subsequent comprehensive cleaning. During the sliding of the movable frame 24, its lower fixed frame 31 drives the rotating rod 32 to move synchronously in the strip groove 13 of the filter plate 12. The gear 34 at the upper end of the rotating rod 32 meshes with the rack 35 on the inner wall of the box 11. The meshing action drives the rotating rod 32 to rotate. The multiple stirring plates 33 on the outer wall of the rotating rod 32 rotate accordingly, stirring the sewage at the bottom of the box 11 to prevent fine sediments in the sewage from accumulating at the bottom of the box 11 and to ensure the uniformity of sewage filtration. Gear 29 on the upper side of gear 234 meshes with rack 28 on the lower side of the hanging plate 27, causing the fixing bar 26 to drive the hanging plate 27 to slide back and forth on the upper part of the moving frame 24 according to the sliding frame 25. This allows the hanging plate 27 to scrape and clean the impurities trapped on the surface of the filter plate 12, preventing the filter holes of the filter plate 12 from becoming clogged. The scraped impurities move with the hanging plate 27 to the extension guide plate 16 and slide into the filter frame 55 of the filter screen mechanism 5. While the double-headed motor 21 is running, its rear output end drives pulley 41 to rotate. Pulley 41 drives pulley 43 and shaft 42 to rotate through synchronous belt 44. Bevel teeth 45 and 46 at the end of shaft 42 mesh with each other, thereby driving shaft 59 between the two loading parts 58. The shaft 59 rotates, and the filter screen frame 55 reciprocates on the rotating wheel 54 via the adapter bar 57 and connecting bar 56. The primary impurities are intercepted by the filter screen frame 55, which slides into the extended guide plate 16. The secondary fine screening is completed with the swing of the filter screen frame 55. The mesh size of the filter screen frame 55 is smaller than that of the filter plate 12, which can further separate the sewage entrained in the impurities and realize the secondary recycling of sewage. The sewage after secondary filtration falls into the trough 52 on the frame 51 and is discharged through the drain outlet 53. The solid impurities intercepted in the filter screen frame 55 are collected in a concentrated manner with the swing, which is convenient for subsequent unified cleaning. In the whole process, the left and right reciprocating sliding of the moving frame 24 and the front and back reciprocating sliding of the sliding frame 25 simultaneously realize the clearing and anti-clogging of the filter plate 12 and the stirring of sewage in the box 11 to prevent accumulation.Furthermore, through the pulley and bevel gear transmission of the linkage mechanism 4, power is synchronously transmitted to the filter screen mechanism 5, realizing secondary fine screening of primary filtration impurities and wastewater recovery. The entire process is driven by a single dual-head motor 21, with each functional module operating in conjunction, requiring no additional power source and significantly reducing energy consumption. Simultaneously, the multi-stage filtration design improves the treatment accuracy of drilling wastewater. Automated clearing, agitation, and screening actions avoid the frequent shutdowns and cleaning issues of traditional equipment, ensuring continuous treatment efficiency of drilling wastewater and effectively solving the problems of impurity blockage, accumulation, and backflow.
