Description

Technical Field

[0001] This utility model belongs to the technical field of filter cap disassembly and assembly equipment, and specifically relates to an auxiliary device for disassembling and assembling filter caps. Background Technology

[0002] The feedstock gas for the natural gas processing unit is associated gas from oil fields, containing a high amount of impurities. The primary basket filter of the feedstock gas compressor requires frequent cleaning. Because the primary basket filter cap is quite heavy (50kg per unit), removing it requires four people to lift it with steel pipes. Furthermore, the surrounding valves and pipelines are complex, so workers must be extremely careful to avoid damaging the equipment. After removal, the primary basket filter cap is placed on the ground. Reinstalling the cap after cleaning the primary basket filter is quite difficult. Placing the removed primary basket filter cap on the accessory pipelines also poses a safety hazard.

[0003] Cleaning the primary basket filter of the raw gas compressor involves a significant amount of time spent disassembling and reassembling its gland. Under normal circumstances, the primary basket filter of the raw gas compressor needs to be cleaned every three days. When the gas quality is poor, it needs to be cleaned at least once a day, making the work labor-intensive. If cleaning is not done in a timely manner, it can lead to insufficient gas intake into the raw gas compressor, causing venting.

[0004] Publication No. CN 202848924 U discloses a pump station filter maintenance lifting device, including: a support, a handle, a rotating cylinder, a riser, an upper beam, a lifting ring, a lower beam, a positioning bolt, an adjusting nut, a center rod, a hook, an auxiliary frame, a reinforcing rib, a lifting frame, connecting bolts, a connecting ring, and a connecting pin. The pump station filter maintenance lifting device is a three-T-shaped combination structure of pipe and rod components. First, the upper part of the support with a fixing hole is connected to the riser and vertically connected to the upper beam in a "T" shape. The upper beam is a telescopic structure with a lifting ring at the right end for hanging a hand-operated hoist to lift the filter screen. Second, the rotating cylinder with a handle is vertically connected to the lower beam in a "T" shape. The rotating cylinder is fitted onto the riser. Similarly, the lower beam is a telescopic structure with a positioning bolt in the middle and a through hole at the right end. A threaded center rod is installed in the through hole, and an adjusting nut is installed at the top. The center rod and the lifting frame are movably connected by a connecting pin to form a third "T" shape. The aforementioned pump station filter lifting device has a sliding connecting bolt at each end of the lifting frame for connecting the filter cover. An auxiliary frame with reinforcing ribs is located at the top. A "U"-shaped hook is positioned between the lifting frame and the auxiliary frame and has a through hole for inserting a connecting pin to connect with the central rod. A connecting ring is located on each side of the lifting frame to connect the auxiliary frame to the lifting frame. Existing technology CN202848924U facilitates the disassembly and assembly of the filter cover, reducing the time and manpower required for disassembly and assembly.

[0005] This utility model provides a new auxiliary device for disassembling and assembling filter caps, which differs from the concept of the existing technology CN 202848924 U. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 As shown, this utility model provides a filter cap removal and installation auxiliary device, including anchor bolts 1, base 2, bearing seat 3, support column 4, crossbeam 5, fixed frame 6, hand-cranked worm gear lift 8, and lifting device 10. The filter cap removal and installation auxiliary device is installed at a suitable position next to the primary basket filter of the raw gas compressor to facilitate filter cleaning operations.

[0023] Anchor bolt 1 is embedded in the concrete foundation at its bottom. The top of anchor bolt 1 is threaded to the bottom of base 2. The upper end of base 2 is rotatably connected to the bottom of support column 4 via bearing seat 3. A crossbeam 5 is horizontally connected to the top of support column 4. Embedding anchor bolt 1 in the concrete foundation makes base 2 more stable. Pushing crossbeam 5 allows it to rotate 360° under the action of bearing seat 3.

[0024] A sleeve 12 is integrally connected to the top of the support column 4, and a crossbeam 5 passes through the sleeve 12. A fixing frame 6 is fixed to the long side of the crossbeam 5. The support column 4 and the sleeve 12 form a T-shaped structure.

[0025] A hand-cranked worm gear lift 8 is installed at the bottom inside the fixed frame 6.

[0026] The hand-cranked worm gear jack 8 includes a housing 11, a lifting handwheel 7, and a lifting screw 9. The lifting handwheel 7 is located at the rear of the bottom of the fixed frame 6. The hand-cranked worm gear jack 8 is existing technology, in which the lifting screw 9 is raised or lowered by rotating the lifting handwheel 7 and utilizing the meshing of the worm gear and the worm.

[0027] The housing 11 of the hand-cranked worm gear lifter 8 is fixed to the bottom of the fixed frame 6. The lifting screw 9 is longitudinally inserted in the fixed frame 6. The top end of the lifting screw 9 is located inside the fixed frame 6, and the bottom end of the lifting screw 9 is located outside the fixed frame 6. The bottom end of the lifting screw 9 is connected to a lifting device 10, which is used to lift the filter cap.

[0028] Rotating the lifting handwheel 7 activates the worm gear transmission within the housing 11 of the hand-cranked worm gear lift 8, allowing the lifting screw 9 to move up and down, thus enabling the lifting device 10 to lift or lower the filter cap. The crossbeam 5 can rotate 360°, driving the fixed frame 6 to rotate 360° as well; this facilitates easy installation and removal of the filter cap.

[0029] Using the filter cap removal and installation auxiliary device of this utility model, the cleaning operation of the primary basket filter of the raw gas compressor, which normally takes 30 minutes, can be reduced by 15 minutes. The required manpower is reduced from 4 to 1 person. At the same time, it avoids the occurrence of personnel injuries and equipment damage caused by personnel fatigue and lack of coordination among the 4 people during the initial cap removal and installation process, which could result in the cap not being placed properly in the safe area.

[0030] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and optimal implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.
