Description

Technical Field

[0001] This utility model belongs to the field of power fluid purification technology for drive systems, and specifically relates to a power fluid circulation and purification device for a hydraulic rodless pump ground drive system. Background Technology

[0002] In the ground drive system of hydraulic rodless pump, the efficiency of the power fluid circulation purification device is directly related to the stable operation and production efficiency of the entire system. With the continuous development of the oil extraction industry, the requirements for the performance of hydraulic rodless pump are becoming increasingly stringent, and the purification accuracy and stability of the power fluid are becoming more and more critical. Among them, the filter screen in the purification device is the first line of defense against solid impurities, and its working condition has a profound impact on the purification effect of the power fluid.

[0003] Currently, there are a large number of solid impurities in the power fluid. This is caused by the complex environment of oil extraction. During extraction, solid materials such as formation sand, debris from equipment wear, and rust from pipelines will mix into the power fluid. During the power fluid circulation and purification process, these solid impurities are very easy to accumulate at the filter screen, causing blockage. Even if the filter element structure inside the purification device has not reached saturation, the external filter screen is often blocked due to the accumulation of solid impurities. This not only hinders the normal flow of the power fluid, but also causes a significant decrease in purification efficiency, which seriously affects the operation of the entire system.

[0004] To solve the problem of filter clogging, operators have to clean the filters frequently. However, existing filters are mostly installed inside the device or pipeline, making disassembly and assembly extremely inconvenient. Disassembling and assembling pipelines not only requires specialized tools and consumes a lot of time and manpower, but may also damage pipelines and related equipment due to improper operation, increasing maintenance costs and the risk of production interruption. In addition, frequent disassembly and assembly may also lead to a decrease in the sealing performance of pipeline connections, causing safety hazards such as power fluid leakage. In view of the defects of existing power fluid circulation purification device filters, such as easy clogging and inconvenient disassembly and assembly, there is an urgent need to develop an innovative filter design and installation method.

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a power hydraulic circulation purification device for a hydraulic rodless pump ground drive system, so as to solve the problems of disassembly and maintenance during the application of the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A power hydraulic circulation purification device for a hydraulic rodless pump ground drive system includes a delivery pipeline, a frame fixedly installed inside the delivery pipeline, a filter mechanism movably installed inside the frame, an elastic limiting mechanism fixedly installed on the top of the filter mechanism, and the filter mechanism is installed inside the frame through the elastic limiting mechanism.

[0008] The filtration mechanism includes a mounting groove, which is opened inside the frame base. A frame is slidably connected inside the mounting groove. A purification filter is bolted inside the frame. A sealing gasket is provided on the outside of the frame. A sealing cover is fixedly installed on the top of the frame. The elastic limiting mechanism is installed on the top of the sealing cover.

[0009] As a preferred technical solution, a sealing gasket is also provided at the bottom of the sealing cover, and the bottom of the sealing gasket on the sealing cover is fitted and connected to the top of the frame base.

[0010] As a preferred technical solution, a collection frame is fixedly installed at the bottom of the conveying pipe on one side of the filter screen input end. The top of the collection frame is connected to the input end of the filter screen inside the conveying pipe. A discharge pipe is fixedly connected to the bottom of the collection frame, and a sealing bottom cover is threadedly connected to the bottom of the discharge pipe.

[0011] As a preferred technical solution, an operating handle is fixedly installed at equal intervals on the outer side of the sealing bottom cover, and a sealing gasket is provided inside the sealing bottom cover, and the sealing bottom cover seals the bottom of the discharge pipe through the sealing gasket.

[0012] As a preferred technical solution, the elastic limiting mechanism includes a rail frame, which is fixedly installed on the top of the sealing cover. A limiting component is provided on the inner side of the rail frame, and an adjusting component is provided on the top of the limiting component. The limiting component and the frame seat are engaged.

[0013] As a preferred technical solution, the limiting component includes a slot and a limiting spring. The limiting spring is fixedly connected to both ends of the inside of the rail frame. A movable block is fixedly connected to the outer end of the limiting spring. A limiting arm is fixedly connected to the outer side of the movable block. A locking block is fixedly installed at the lower inner end of the limiting arm. The slot is opened in the middle of both sides of the frame base, and the locking block is inserted into the slot.

[0014] As a preferred technical solution, the adjustment component includes a side rail, which is fixedly connected to the middle of one side of the rail frame. A sliding block is slidably connected inside the rail frame. A double-ended hinge seat is fixedly connected to the top of the sliding block. A linkage rod is hinged to both sides of the double-ended hinge seat. The outer end of the linkage rod is hinged to the top of the sliding block. A bridge-type handrail is fixedly connected to the top of the double-ended hinge seat.

[0015] In summary, the present invention has the following main advantages:

[0016] First, by setting up a filtration mechanism, the frame is precisely embedded into the mounting groove of the frame seat during use. The elastic limiting mechanism assists in the snap-fit. After the frame is in place, the sealing cover covers the top of the frame seat to form an effective seal and prevent the power fluid from leaking. When the power fluid flows through the conveying pipeline, it first passes through the purification filter screen to efficiently filter out particulate impurities. Activated carbon purification cores can be added inside or behind the filter screen as needed to deeply purify the power fluid using its microporous structure, removing odors, pigments, and organic pollutants. The purification filter core is set vertically. Impurities blocked by the filter screen fall into the bottom collection frame under the action of gravity. When cleaning, the operating handle drives the sealing bottom cover to rotate and detach from the discharge pipe, which makes it easy to clean the collection frame and reduces maintenance costs.

[0017] Secondly, by setting up an elastic limiting mechanism, during the installation and maintenance of this device, one can pull the sliding block by holding the bridge-type handrail, which drives the double-end hinge seat, and then pull the linkage rod, causing the movable block to move outward against the spring force of the limiting spring, and the locking block to disengage from the slot. At this time, the frame can be inserted into the installation slot. After releasing the handrail, the limiting spring returns to its original position, driving the movable block and the locking block back to their original positions, and the locking block inserts into the slot, completing the quick installation of the sealing top cover. When disassembly and maintenance are required, simply pull the bridge-type handrail again and repeat the above operation to disengage the locking block from the slot, making it easy to remove the sealing cover. This facilitates a comprehensive inspection of the purification filter and greatly improves the ease of use and maintenance efficiency of the device. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 4 The embodiment of the power hydraulic circulation purification device for a hydraulic rodless pump ground drive system includes a conveying pipe 1, a frame 4 fixedly installed inside the conveying pipe 1, a filter mechanism 3 movably installed inside the frame 4, an elastic limiting mechanism 2 fixedly installed on the top of the filter mechanism 3, and the filter mechanism 3 is installed inside the frame 4 through the elastic limiting mechanism 2.

[0025] The filter mechanism 3 includes a mounting groove 31, which is located inside the frame base 4. A frame 32 is slidably connected inside the mounting groove 31. A purification filter 33 is bolted inside the frame 32. A sealing gasket is provided on the outside of the frame 32. A sealing cover 34 is fixedly installed on the top of the frame 32. An elastic limiting mechanism 2 is installed on the top of the sealing cover 34. In this hydraulic rodless pump ground drive system power hydraulic circulation purification device, the frame base 4 inside the delivery pipeline 1 plays a key supporting role. When the filter mechanism 3 needs to be installed, the frame 32 can smoothly slide into the mounting groove 31 inside the frame base 4 thanks to the good fit between the sealing gasket and the mounting groove 31. The elastic limiting mechanism 2 enables convenient and stable installation. When the elastic limiting mechanism 2 is in operation, by operating its position on the top of the sealing cover 34... Components, such as the hand-held bridge handrail 235, can be slid by pulling and sliding the sliding block 232, which in turn moves the double-end hinge seat 233 and pulls the linkage rod 234. This causes the movable block 223 to move outward against the elastic force of the limit spring 222, so that the locking block 225 disengages from the slot 221. At this time, the frame 32 can be smoothly inserted into the mounting slot 31. After releasing the hand, the limit spring 222 returns to its original position, causing the movable block 223 and the locking block 225 to return to their original positions. The locking block 225 is inserted into the slot 221, which firmly fixes the frame 32 in the frame seat 4. When the power fluid flows in the delivery pipe 1, it will first pass through the purification filter 33 fixed by bolts inside the frame 32. The purification filter 33 efficiently filters out particulate impurities in the power fluid. At the same time, the sealing cover 34 on the top of the frame 32, together with the sealing gasket, can effectively prevent power fluid leakage and ensure the stable operation of the purification process.

[0026] refer to Figures 3-4The elastic limiting mechanism 2 includes a rail frame 21, which is fixedly installed on the top of the sealing cover 34. A limiting component 22 is provided on the inner side of the rail frame 21, and an adjusting component 23 is provided on the top of the limiting component 22. The limiting component 22 and the frame base 4 are engaged. The limiting component 22 includes a slot 221 and a limiting spring 222. The limiting spring 222 is fixedly connected to both ends of the inner side of the rail frame 21. A movable block 223 is fixedly connected to the outer end of the limiting spring 222. A limiting arm 224 is fixedly connected to the outer side of the movable block 223. A locking block 225 is fixedly installed on the lower inner side of the limiting arm 224. The slot 221 is opened on both sides of the frame base 4. The locking block 225 is inserted into the slot 221. The adjusting component 23 includes a side rail 231, which is fixedly connected to the middle of one side of the rail frame 21. A sliding block 232 is slidably connected inside the rail frame 21. A double-ended hinge seat 233 is fixedly connected to the top of the sliding block 232. A linkage rod 234 is hinged to both sides of the double-ended hinge seat 233. The outer end of the linkage rod 234 is hinged to the top of the sliding block 232. A bridge-type handrail 235 is fixedly connected to the top of the double-ended hinge seat 233. In the elastic limiting mechanism 2 of the power hydraulic circulation purification device for the ground drive system of this hydraulic rodless pump, the rail frame 21 is firmly installed on the sealing cover 3. 4. At the top, the overall frame is constructed. When the filter mechanism 3 needs to be installed, hold the bridge-type handrail 235, which is connected to the double-end hinge seat 233. Pulling the bridge-type handrail 235 will cause the double-end hinge seat 233 to slide within the side rail 231. The linkage rods 234 hinged on both sides of the double-end hinge seat 233 will move accordingly. Since the outer end of the linkage rod 234 is hinged to the top of the movable block 223, the movement of the linkage rod 234 will cause the movable block 223 to overcome the elastic force of the limit springs 222 at both ends inside the rail frame 21 and move outward. The outward movement of the movable block 223 will cause the outer limit arm 224 to move synchronously, thereby causing the lower inner end of the limit arm 224 to lock the block 225. The frame 32 can be easily inserted into the mounting slot 31 of the frame base 4 by disengaging from the slots 221 in the middle of both sides of the frame base 4. After installation, the bridge handle 235 is released, the limit spring 222 returns to its original state, and the resulting tension pulls the movable block 223 inward, which drives the limit arm 224 and the block 225 back to their original positions. The block 225 is then accurately reinserted into the slot 221, completing the secure connection of the frame 32 and achieving stable installation of the filter mechanism 3. When the filter mechanism 3 needs to be disassembled and repaired, the above operation is repeated to disengage the block 225 from the slot 221, making it easy to remove the sealing cover 34 for subsequent maintenance.

[0027] refer to Figures 1-3The bottom of the sealing cover 34 is also provided with a sealing gasket. The bottom of the sealing gasket on the sealing cover 34 is fitted and connected to the top of the frame seat 4. A collection frame 5 is fixedly installed on the side of the bottom of the conveying pipe 1 located at the input end of the filter screen. The top of the collection frame 5 is connected to the input end of the filter screen in the conveying pipe 1. A discharge pipe 6 is fixedly connected to the bottom of the collection frame 5. A sealing bottom cover 7 is threadedly connected to the bottom of the discharge pipe 6. An operating handle 8 is fixedly installed at equal intervals on the outside of the sealing bottom cover 7. A sealing gasket is provided inside the sealing bottom cover 7. The sealing bottom cover 7 seals the bottom of the discharge pipe 6 through the sealing gasket. In this hydraulic rodless pump ground drive system power fluid circulation purification device, the sealing gasket at the bottom of the sealing cover 34 is tightly fitted with the top of the frame seat 4 to form a good sealing structure, effectively preventing the power fluid from leaking from the connection between the sealing cover 34 and the frame seat 4 when flowing through the filter mechanism 3, ensuring the sealing and stability of the purification process. When the power fluid flows When the impurities are purified by the filter screen inside the conveying pipeline 1, the impurities intercepted by the filter screen fall downwards into the collection frame 5 located at the bottom of the conveying pipeline 1, on the side of the filter screen input end, under the action of gravity and guided by the tilt angle of the filter screen or the flow of the kinetic fluid. As the usage time increases, the impurities in the collection frame 5 gradually increase. When cleaning is required, the operator holds the operating handle 8, which is installed at equal intervals on the outside of the sealing bottom cover 7, and loosens the threaded connection between the sealing bottom cover 7 and the bottom of the discharge pipe 6 by rotating it. Since there is a sealing gasket inside the sealing bottom cover 7, under normal conditions, the sealing gasket fits tightly against the bottom of the discharge pipe 6 to ensure the sealing of the discharge pipe 6 and prevent impurities from leaking. When the sealing bottom cover 7 is rotated away from the discharge pipe 6, the discharge pipe 6 opens, and the impurities in the collection frame 5 can be discharged. After cleaning, the sealing bottom cover 7 is tightened again, and the sealing gasket is used to seal the bottom of the discharge pipe 6 again, ensuring the continuous and stable operation of the device.

[0028] Operating principle and advantages: In the actual application of this device, the filter mechanism 3 plays a crucial role. When the device is put into use, the operator accurately inserts the frame 32 into the preset installation groove 31 in the frame seat 4. During this process, the elastic limiting mechanism 2 plays an auxiliary snap-fit ​​installation function to ensure that the frame 32 is installed firmly. After the frame 32 is successfully installed in the installation groove 31, the sealing cover 34 automatically covers the top of the frame seat 4 to form a good sealing structure, effectively preventing power fluid leakage and ensuring the safety and stability of the system operation.

[0029] During the power fluid transportation process, the power fluid flows continuously in the transportation pipeline 1 and is first filtered and screened by the purification filter 33. The purification filter 33 is manufactured with a special process, which can efficiently filter out particulate impurities mixed in the power fluid and significantly improve the cleanliness of the power fluid. To further optimize the filtration effect, an activated carbon purification core structure can be flexibly installed inside or behind the purification filter 33 according to actual needs. The activated carbon purification core utilizes its rich microporous structure and strong adsorption performance to deeply purify the power fluid and effectively remove odors, pigments and some organic pollutants.

[0030] It is worth mentioning that the purification filter element adopts a vertical setting. This design has unique advantages. During the process of filtering out impurities, the impurities blocked by the purification filter screen 33 will fall into the collection frame 5 at the bottom under the action of gravity. When it is necessary to clean and maintain the collection frame 5, the operator only needs to operate the handle 8 to drive the sealing bottom cover 7 to rotate around a specific axis. As the sealing bottom cover 7 rotates, it gradually separates from the discharge pipe 6. At this time, the discharge pipe 6 is opened, and the operator can conveniently and quickly clean the inside of the collection frame 5, effectively reducing maintenance costs and improving the efficiency of the device.

[0031] The elastic limiting mechanism 2 demonstrates a high degree of design ingenuity and ease of operation during the installation and maintenance of this device. During the installation phase, the operator holds the bridge-type handrail 235 and applies force to pull the sliding block 232, allowing it to slide smoothly on a specific track. The sliding of the sliding block 232 causes the connected double-end hinge seat 233 to move synchronously. The movement of the double-end hinge seat 233 further pulls the linkage rod 234. During the pulling process, the linkage rod 234 applies a pulling force to the two linkage rods 234 simultaneously, causing the movable block 223 to overcome the elastic force of the limiting spring 222 and move outward. During this process, the limiting spring 222 is stretched and stores elastic potential energy.

[0032] When the movable block 223 moves outward, it drives the connected locking block 225 to move outward synchronously until the locking block 225 is completely disengaged from the slot 221. At this time, the operator can smoothly insert the frame 32 into the installation slot 31. After installation, the operator releases the bridge handrail 235, and the limit spring 222 immediately releases the stored elastic potential energy, returns to the initial state, and pulls the movable block 223 to move inward. The movement of the movable block 223 drives the limit locking arm 224 to move synchronously, thereby pushing the locking block 225 to re-insert into the slot 221. Through the tight limiting cooperation between the locking block 225 and the slot 221, the quick installation and stable fixation of the sealed top cover are achieved.

[0033] When the device needs to be disassembled and repaired, the operator only needs to pull the bridge handle 235 again to move the double-end hinge 233. The double-end hinge 233 pushes the linkage rod 234, which in turn moves the movable block 223 outward. The outward movement of the movable block 223 drives the limit arm 224 to move, causing the locking block 225 to quickly disengage from the locking slot 221. At this time, the operator can easily remove the sealing cover 34, which facilitates the comprehensive disassembly and repair of the purification filter 33 of the filtration mechanism 3. This design greatly improves the convenience of the device in the overall use process, effectively reduces the maintenance difficulty, and improves the maintainability and reliability of the equipment.
