Description

Technical Field

[0001] This invention relates to the field of drilling mud treatment technology, specifically to an intelligent drilling mud environmental protection filter press mechanism. Background Technology

[0002] In current oilfield production activities, drilling and extraction generate a large amount of waste drilling mud. Studies show that most oil drilling mud is water-based, highly alkaline, and corrosive. Coupled with transportation difficulties, effective treatment and local discharge are crucial. Randomly dumping waste mud around the site or directly discharging it will cause pollution and hinder the sustainable development of oilfields. Therefore, people have begun to realize the importance of environmentally friendly treatment of oilfield waste mud. Plate and frame filter presses are commonly used equipment in the environmentally friendly treatment process of drilling mud. A plate and frame filter press consists of rows of filter plates forming a series of closed filter chambers. The working principle of the filter press is to use the pressure difference created by the pressurizing equipment to first force the mud into the sealed filter chambers. By squeezing the mud and creating an internal and external pressure difference, the mud is filtered through the filter screen, leaving solid particles, thus achieving solid-liquid separation.

[0003] A Chinese patent application with publication number CN117430304A discloses a filter press device for environmentally friendly treatment of drilling mud, including a frame, a feed pipe, a thrust plate, a filter chamber, a compression plate, a drive device, a pull plate device, and a filter press reinforcement assembly. The filter press reinforcement assembly includes a mounting plate, an expandable bladder, and a corrugated hose. The mounting plate is sealed to adjacent filter plates to form a closed chamber, ensuring that the mud only enters the closed chamber of the filter chamber during the filter press process and does not enter other spaces. The deformable characteristics of the corrugated hose also ensure the stability of the connection. The expandable bladder expands by filling with a medium, and after expansion, it compresses adjacent filter plates, further increasing the compressive force on the preliminarily filtered mud material in the filter chamber, thereby reducing the water content of the mud material and improving the filter press effect. The expanded expandable bladder compresses the filter plates and retracts upon restoration, providing unloading space for the filtered mud material, which helps improve unloading efficiency and thus improves the performance of the filter press device.

[0004] However, this filter press has the following drawbacks in practical use:

[0005] 1. In order to increase the extrusion pressure on the material, a filter press reinforcement component is added between each filter plate in this device. This not only reduces the number of filterable structures in the whole device, but also occupies a large space. Overall, it is not conducive to use in drilling engineering. Therefore, its structure still needs to be improved.

[0006] 2. In this device, there is no structure for cleaning the filter plates after the mud is filtered, which requires additional cleaning operations. This results in the overall structure not being able to be used intelligently and efficiently. When used in drilling projects, this is undoubtedly time-consuming and labor-intensive, affecting the working efficiency of the entire device. Summary of the Invention

[0031] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0032] 1. This intelligent drilling mud environmental protection filter press mechanism, through the cooperation of a first locking block and a first locking slot, and a second locking block and a second locking slot, enables the horizontal splicing of multiple frames. After the multiple frames are spliced, a vacuum pump is used to evacuate air from the connecting pipe and the inside of the negative pressure chamber, so that the inside of the negative pressure chamber is kept in a negative pressure state. Under the action of the connecting channel, the inside of the first locking slot and the second locking slot are in a negative pressure state. When the first locking block and the second locking block are respectively embedded in the first locking slot and the second locking slot, the negative pressure state at this time enables the multiple frames to fit tightly together. Combined with the hydraulic system, it ensures that the mud between the multiple filter screens can be fully squeezed, thereby improving the filter press effect.

[0033] 2. This intelligent drilling mud environmental protection filter press mechanism, when using a vacuum pump to perform negative pressure suction on the first and second clamping blocks, can monitor the pressure in the second branch pipe in real time through the set negative pressure sensor. Once the first or second clamping block in a plate frame becomes unlocked and leaks air, the negative pressure sensor can sense the pressure change, thereby helping people to understand that there is an unlocked state between the plate frames, which is not conducive to filter press work at this time, realizing intelligent monitoring and improving the use effect of the device;

[0034] 3. This intelligent drilling mud environmental protection filter press mechanism, through the cooperation of the solenoid valves on the first and second branch pipes, combined with the use of water pump and vacuum pump, enables the entire connecting pipe, negative pressure chamber and connecting channel to lock each plate frame before and during the filter press, and to achieve reverse flushing of the filter screen after the filter press, thereby improving the overall performance and making it more conducive to the long-term use of the device.

[0035] 4. This intelligent drilling mud environmental protection filter press mechanism, when backwashing the filter screen with clean water, uses a soft material for the annular sleeve, which can wrap around the outside of the first locking block. After the first locking block separates from the first locking groove, the annular sleeve is filled with clean water. This allows the fixed blocks and the frame to automatically move away from each other during backwashing of the filter screen, which is conducive to the falling of the filter cake. It also enables intelligent and automatic spacing adjustment, making it more convenient to use.

[0036] 5. This intelligent drilling mud environmental protection filter press mechanism can monitor the spraying effect of the nozzles in real time through the set camera, thereby improving the cleaning effect. At the same time, when the slider descends, the gear descends accordingly. Under the action of the rack, the gear drives the second rotating shaft to rotate. Combined with the use of transmission components, several first rotating shafts can rotate, which in turn drives the scraper to rotate. The scraper can scrape away water from the visible window on the surface of the fixed box, which is convenient for the camera inside the fixed box to observe effectively and improve the observation effect.

[0058] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0059] Please see Figure 1 - Figure 17 The intelligent drilling mud environmental protection filter press mechanism includes a frame 1, an extrusion plate 2 slidably mounted on the frame 1, a positioning plate 3 fixed on the frame 1, a hydraulic system 4 located on one side of the frame 1, and a feed pipe 5 penetrating the middle of the positioning plate 3. It also includes:

[0060] The filter press assembly 6 is provided in several parts and is located between the extrusion plate 2 and the positioning plate 3;

[0061] Cleaning component 7 is mounted on rack 1;

[0062] The filter press assembly 6 includes a frame 601 slidably mounted on the frame 1, with a first chamber 6011 symmetrically opened on one side of the frame 601 and a second chamber 6012 opened on the other side of the frame 601. A through hole 6013 communicating with the interior of the second chamber 6012 is opened at the center of the side of the frame 601 facing the first chamber. A filter screen 602 is disposed inside the first chamber 6011.

[0063] The filter press assembly 6 also includes fixing blocks 603 disposed on both sides of the frame 601, and two fixing blocks 603 are disposed on both sides of each frame 601, and are symmetrically fixed to the upper and lower ends of the side of the frame 601 respectively.

[0064] The frame 601 has a third chamber 6014 at both the top and bottom, and the third chamber 6014 is connected to the first chamber 6011 through a hole 6015. The fixing block 603 has a water outlet chamber 6031 and a negative pressure chamber 6032 inside. The water outlet chamber 6031 corresponds to and is connected to the third chamber 6014. The side of the fixing block 603 is provided with a water outlet pipe 604 connected to the water outlet chamber 6031 and a connecting pipe 605 connected to the negative pressure chamber 6032.

[0065] A first locking block 606 is fixed to one side of the fixing block 603, and a first locking groove 6033 that mates with the first locking block 606 is opened on the other side of the fixing block 603. A second locking block 607 is elastically connected to both the upper and lower ends of the first locking block 606. A second locking groove 6034 that mates with the second locking block 607 is opened at both the upper and lower ends of the first locking groove 6033. A connecting channel 6035 for connecting the negative pressure chamber 6032, the first locking groove 6033 and the second locking groove 6034 is opened inside the fixing block 603.

[0066] In summary, when the entire device is needed, the hydraulic system 4 connects to the extrusion plate 2, allowing the extrusion plate 2 to move towards the positioning plate 3. During the movement of the extrusion plate 2, the multiple frames 601 can fit together, thus achieving the desired connection. Figure 6As can be seen, when multiple frames 601 are bonded together, the second chamber 6012 in the left frame 601 will bond with the filter screen 602 in the right frame 601, and this cycle continues. Therefore, based on this, after the multiple frames 601 are bonded to a certain extent, slurry is injected into the feed pipe 5. The feed pipe 5 corresponds to and is connected to the through hole 6013, allowing the slurry to enter the through hole 6013 and then pass through the second chamber 6012 connected to the through hole 6013, so that the slurry is filtered by the filter screen 602. In the filter, the filter residue is squeezed into a filter cake between the second chamber 6012 and the filter screen 602, while the water filtered by the filter screen 602 enters the first chamber 6011 and then enters the third chamber 6014 through the hole 6015. Since the third chamber 6014 is connected to the water outlet chamber 6031, the filtered water can enter the water outlet chamber 6031 and finally flow out from the water outlet pipe 604. Through the external collection structure, the water flowing out of the water outlet pipe 604 can be collected and further treated.

[0067] In addition, such as Figure 6 , Figure 7 and Figure 8 As shown, the first locking block 606 can be inserted into the first locking slot 6033, while the second locking block 607 is elastically connected to the first locking block 606, allowing the second locking block 607 to extend and retract within the first locking slot 6034. Therefore, by the cooperation of the first locking block 606 with the first locking slot 6033 and the second locking block 607 with the second locking slot 6034, multiple frames 601 can be horizontally spliced ​​together. After the multiple frames 601 are spliced ​​together, the negative pressure chamber 6032 is connected through the connecting pipe 605. The internal air extraction keeps the negative pressure chamber 6032 under negative pressure. Under the action of the connecting channel 6035, the first slot 6033 and the second slot 6034 are under negative pressure. When the first block 606 and the second block 607 are respectively embedded in the first slot 6033 and the second slot 6034, the negative pressure at this time allows the multiple frames 601 to fit tightly together. Combined with the hydraulic system 4, this ensures that the mud between the multiple filter screens 602 can be fully squeezed, thereby improving the filter pressing effect.

[0068] In addition, it is worth mentioning that in this embodiment, the side of the extrusion plate 2 facing the frame 601 is also provided with a fixing block 603 and a first locking block 606, a second locking block 607 and other structures, and the side of the positioning plate 3 facing the frame 601 is also provided with a fixing block 603 and a first locking groove 6033, a second locking groove 6034 and other structures, so that the extrusion plate 2, multiple frames 601 and positioning plate 3 can be sequentially snapped together to ensure the effective operation of the device;

[0069] Meanwhile, in this embodiment, the hydraulic system 4 is a mature technology in existing plate and frame filter presses, so its specific structure and working principle will not be described in detail here. Its function is to drive the extrusion plate 2 to move toward the positioning plate 3, so as to facilitate the extrusion and filtration of the filter press assembly 6.

[0070] Specifically, the elastic connection structure between the first locking block 606 and the second locking block 607 is as follows: a through groove 6061 is provided inside the first locking block 606, and the opposite ends of the two second locking blocks 607 extend into the through groove 6061 and are connected to each other by a spring 608.

[0071] In the initial state, under the action of spring 608, both first locking blocks 606 are located inside the through groove 6061, with their outer end faces flush with the outer surface of the first locking block 606, allowing the first locking block 606 to be locked into the first locking slot 6033. After the first block is locked into the first locking slot 6033, negative pressure is provided to the negative pressure chamber 6032. Under the action of negative pressure, the second locking block 607 extends into the second locking slot 6034, causing spring 608 to be stretched, thus ensuring the mutual locking of the second locking block 607 and the second locking slot 6034, thereby providing a better locking effect. When the negative pressure effect inside the negative pressure chamber 6032 is released, under the action of spring 608, the two second locking blocks 607 retract into the through groove 6061, allowing the first locking block 606 to be removed from the first locking slot 6033.

[0072] Furthermore, in this embodiment, if a negative pressure is to be generated in the connecting pipe 605, the following structure is required: a main pipe 609 is connected to the end of the connecting pipe 605, and a first branch pipe 610 is connected to the main pipe 609, a second branch pipe 611 is connected to the first branch pipe 610, and a solenoid valve 612 is provided on both the first branch pipe 610 and the second branch pipe 611.

[0073] A water pump 615 and a vacuum pump 613 are installed on the side of the hydraulic system 4. The output end of the water pump 615 is connected to the end of the first branch pipe 610, and the absorption end of the vacuum pump 613 is connected to the end of the second branch pipe 611.

[0074] A negative pressure sensor 614 is also installed on the second branch pipe 611;

[0075] Specifically, during use, when the vacuum pump 613 is started via the external controller, the vacuum pump 613 generates negative pressure inside the second branch pipe 611. At this time, the switch of the solenoid valve 612 on the first branch pipe 610 is closed, and the switch of the solenoid valve 612 on the second branch pipe 611 is opened. The negative pressure generated by the vacuum pump 613 can generate negative pressure inside the second branch pipe 611, the main pipe 609, and the connecting pipe 605, thereby generating negative pressure inside the negative pressure chamber 6032. This completes the locking of the first locking block 606 and the second locking block 607, ensuring the tight fit between the various frames 601 and improving the pressure filtration effect.

[0076] Meanwhile, when the vacuum pump 613 is used to clamp the first locking block 606 and the second locking block 607 under negative pressure, the negative pressure sensor 614 can monitor the pressure in the second branch pipe 611 in real time. Once the first locking block 606 or the second locking block 607 in a certain plate frame becomes unlocked and leaks air, the negative pressure sensor 614 can sense the pressure change, thereby helping people to understand that there is an unlocked state between the plate frames, which is not conducive to the pressure filtration work at this time. This realizes intelligent monitoring and improves the use effect of the device.

[0077] Furthermore, in this embodiment, the fixed block 603 is also provided with a conical cavity 6036 for connecting the water outlet cavity 6031 and the connecting channel 6035. A connecting strip 616 is fixed inside the conical cavity 6036. The cross-sectional area of ​​the connecting strip 616 is smaller than the area of ​​the conical cavity 6036, so it will not block the inside of the conical cavity 6036. A plug rod 618 passes through the middle of the connecting strip 616, and a conical block 617 that cooperates with the inner wall of the conical cavity 6036 is fixed at the end of the plug rod 618 facing the connecting channel 6035.

[0078] When using, such as Figure 8 As shown, due to the conical structure on the conical block 617 and the conical cavity 6036, when the negative pressure is inside the negative pressure cavity 6032, the conical block 617 will block the conical part inside the conical cavity 6036, thereby making the connection channel 6035 and the water outlet cavity 6031 not connected.

[0079] After the filter press is completed, the electromagnet switch on the second branch pipe 611 and the vacuum pump 613 switch are turned off, while the solenoid valve 612 switch and the water pump 615 switch on the first branch pipe 610 are turned on. The input end of the water pump 615 is connected to an external tap water pipe or a clean water pipe, so that the water pump 615 can inject clean water from the first branch pipe 610 into the main pipe 609, and then from the main pipe 609 into the connecting pipe 605 and the negative pressure chamber 6032. At this time, the negative pressure chamber 6032 becomes a high-pressure environment with clean water, and the clean water flows through... After passing through the connecting channel 6035, the conical block 617 can be disengaged from the conical part inside the conical cavity 6036, and the cleaning water will enter the interior of the outlet cavity 6031. Before this, the valve at the end of the outlet pipe 604 is closed, so that the cleaning water can enter the interior of the first chamber 6011 after passing through the outlet cavity 6031 and the hole 6015. This will flush the side of the filter screen 602 facing the first chamber 6011 in the reverse direction, thus making it less likely for the filter residue on the filter screen 602 to clog the holes 6015 of the filter screen 602, achieving a better cleaning effect.

[0080] In other words, based on the above working principle, it can be concluded that this structure has the following effects: through the cooperation of the solenoid valves 612 on the first branch pipe 610 and the second branch pipe 611, combined with the use of the water pump 615 and the vacuum pump 613, the entire connecting pipe 605, the negative pressure chamber 6032 and the connecting channel 6035 can lock each plate and frame before and during the filtration process, and can also achieve reverse rinsing of the filter screen 602 after filtration, thereby improving the overall performance and making it more conducive to the long-term use of the device.

[0081] Furthermore, in this embodiment, an annular groove 619 is provided on the side of the fixing block 603, and an annular sleeve 620 sleeved on the outside of the first locking block 606 is fixed inside the annular groove 619; every two adjacent fixing blocks 603 are connected to each other through the annular sleeve 620.

[0082] When using, combine Figure 8 As can be seen, the annular sleeve 620 connects the various fixing blocks 603. When the filter screen 602 is backwashed, even if the first locking block 606 is disengaged from the first locking groove 6033, the cleaning water will not overflow under the action of the annular sleeve 620. The advantage of this is that when the filter screen 602 is backwashed with cleaning water, the annular sleeve 620 is made of soft material, which allows it to wrap around the outside of the first locking block 606. After the first locking block 606 is disengaged from the first locking groove 6033, the cleaning water fills the annular sleeve 620, which can achieve automatic separation between the fixing blocks 603 and the frame 601 when the filter screen 602 is backwashed. This facilitates the falling of the filter cake, realizes intelligent and automatic spacing adjustment, and makes it more convenient to use.

[0083] Of course, correspondingly, the fixing blocks 603 on the extrusion plate 2 and the positioning plate 3 are also provided with corresponding annular sleeves 620 or annular grooves 619 to form a continuous sealing structure.

[0084] Furthermore, in this embodiment, the frame 1 includes two support plates 101, and the bottom of each of the two support plates 101 is provided with casters. A guide rod 103 and a bearing plate 102 are fixed between the two support plates 101. The guide rod 103 passes through the fixing block 603 and is slidably sleeved with the fixing block 603.

[0085] Cleaning component 7 is mounted on support plate 102;

[0086] Waste liquid collection tanks 104 are also provided at the bottom of the two support plates 101;

[0087] In use, the guide rod 103 can limit and guide the extrusion plate 2 and the frame 601 to improve stability, while the fixing block 603 on the positioning plate 3 is detachably fixed to the guide rod 103, so that the positioning plate 3 can keep its position unchanged.

[0088] Meanwhile, the waste liquid collection tank 104 is used to collect the filter cake after pressure filtration, which facilitates subsequent unified collection and treatment.

[0089] Furthermore, in this embodiment, the cleaning component 7 includes a guide rail 701 fixed to the side of the support plate 102, and a sliding frame 702 slidably disposed on the guide rail 701.

That is, the output end of the first motor 704 is connected to the roller 703. The roller 703 and the guide rail 701 are directionally slidably engaged. When the first motor 704 is started by the control switch, the first motor 704 drives the roller 703 to rotate, so that the roller 703 can move along the guide rail 701, thereby facilitating the movement of the entire cleaning component 7.

[0090] The cleaning assembly 7 also includes a vertical rod 705 fixed to the top of the sliding frame 702, and a top rod 706 fixed to the top of the vertical rod 705. A slider 707 is slidably mounted on the vertical rod 705, and a driving component 708 for driving the slider 707 to rise or fall is mounted on the top rod 706. A vertical tube 709 is fixed on the slider 707, and a horizontal tube 710 is mounted at the bottom of the vertical tube 709. Several nozzles 711 are mounted on the horizontal tube 710.

[0091] A third branch pipe 8 is also provided on the first branch pipe 610, and a solenoid valve 612 is provided on the third branch pipe 8. The end of the third branch pipe 8 is connected to the vertical pipe 709.

[0092] In use, the drive unit 708 can drive the slider 707 to descend, which in turn causes the vertical pipe 709 and the horizontal pipe 710 to descend. In this way, the nozzle 711 corresponds to the filter screen 602. After the water pump 615 is turned on, the cleaning water can be sprayed out from the nozzle 711 after being connected to the vertical pipe 709 through the third branch pipe 8, thus cleaning the surface of the filter screen 602.

[0093] Furthermore, in this embodiment, a connecting plate 712 is fixed on the horizontal tube 710, and a row of several fixing boxes 713 are arranged on the side of the connecting plate 712 facing the nozzle 711. A camera 714 is arranged inside the fixing box 713, and a viewing window is arranged on the end of the fixing box 713 facing the nozzle 711.

[0094] The spraying effect of the nozzle 711 can be observed in real time by the camera 714, which can help improve the cleaning effect. In addition, in order to improve the alignment effect, a camera 714 is also provided on the sliding frame 702 to achieve visual positioning and ensure that the vertical tube 709 and the horizontal tube 710 in the cleaning component 7 correspond to the two adjacent frames 601, so as to facilitate the rising or falling.

[0095] Furthermore, in this embodiment, a first rotating shaft 716 is rotatably connected to the top of the fixing box 713, and a scraper 717 is sleeved on the first rotating shaft 716; multiple first rotating shafts 716 are connected to each other through a transmission member 718; a second rotating shaft 719 is rotatably connected to the side of the slider 707, and a gear 720 is sleeved on the second rotating shaft 719; a rack 721 that meshes with the gear 720 is provided on the side of the vertical rod 705; the second rotating shaft 719 is connected to any one of the first rotating shafts 716 in one row through a transmission member 718.

[0096] Furthermore, in this embodiment, the transmission component 718 is a synchronous belt and synchronous pulley structure, and the specific connection method is existing technology, which will not be described in detail here;

[0097] Please refer to the following carefully when using it. Figure 16 and Figure 17 When the slider 707 descends, the gear 720 descends accordingly. Under the action of the rack 721, the gear 720 drives the second rotating shaft 719 to rotate. Combined with the use of the transmission component 718, several first rotating shafts 716 can rotate, thereby driving the scraper 717 to rotate. This allows the scraper 717 to remove moisture from the visible window on the surface of the fixed box 713, making it easier for the camera 714 inside the fixed box 713 to observe effectively and improving the observation effect.

[0098] Furthermore, in this embodiment, the driving component 708 includes a second motor 7081 mounted on the top of the top rod 706, and the output end of the second motor 7081 is connected to a winding roller 7082. Two connecting ropes 7083 are wound on the winding roller 7082, and the two connecting ropes 7083 are respectively connected to the top of the two sliders 707.

[0099] In use, after the second motor 7081 is started by controlling the switch, the winding roller 7082 rotates accordingly, thereby winding or unwinding the connecting rope 7083 to complete the raising or lowering of the slider 707.
