Description

Technical Field

[0001] This utility model relates to the field of valve box processing technology, specifically a cooling device for valve box processing. Background Technology

[0002] A valve box is a device used for centralized control of multiple valves or valve components. By combining multiple shut-off valves or shut-off check valves into a single structure, it enables unified management and optimized layout of pipeline systems.

[0003] A search revealed a Chinese patent document disclosing a cooling device for valve box processing [Announcement No.: CN216039689U]. This cooling device for valve box processing includes a cooling pool, a vertically upward gantry frame in the middle of the cooling pool, an air collecting hood that can be raised and lowered, an air guide pipe on the top frame of the gantry frame, the end of the air guide pipe being connected to the air collecting hood via a corrugated telescopic guide pipe, and a suction fan fixed on the top frame of the gantry frame.

[0004] The cooling device for valve box processing disclosed in this patent can absorb the evaporated gas by raising and lowering the air collecting hood, thus preventing steam from spreading into the working environment. However, since the steam contains some grease or impurities, after long-term use, a large amount of grease or impurities will remain inside the fan, affecting the normal use of the fan and thus affecting the steam collection effect. Utility Model Content

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7As shown, a cooling device for valve box processing includes a cooling pool 1 and a gantry frame 5 disposed on its outer side. Electric push rods 2 are disposed on both sides of the top of the gantry frame 5. The output end of the electric push rod 2 penetrates through the top of the gantry frame 5. A fixing plate 8 is fixedly connected to the output end of the electric push rod 2. A suction hood 3 is fixedly connected to the other side of the fixing plate 8. A connecting pipe 11 is connected to the top of the suction hood 3. The connecting pipe 11 is a retractable flexible hose. A filter structure 6 is disposed at the other end of the connecting pipe 11. The filter structure 6 includes a connecting sleeve 61 rotatably connected to the surface of the suction pipe of a fan 4. The other end of the connecting sleeve 61 is connected to the surface of the connecting pipe 11. The threaded connection includes a filter 62 inside the connecting sleeve 61, which filters the air drawn in by the suction hood 3, intercepting impurities such as oil or dust to prevent them from entering the fan 4 and causing damage. The threaded connection between the connecting sleeve 61 and the connecting pipe 11 also facilitates the replacement of the filter 62. The fan 4 is mounted on the top of the gantry frame 5, and a transmission structure 9 is installed inside the gantry frame 5. The transmission structure 9 includes a rack plate 91 and a gear 92 meshing with the rack plate 91. A rotating shaft 93 is fixedly connected to the front side of the gear 92, and a first cone is fixedly connected to the other end of the rotating shaft 93. Gear 94, the surface of the first bevel gear 94 meshes with the second bevel gear 95. The right side of the second bevel gear 95 is fixedly connected to the rotating shaft of the flip plate 102. When the suction hood 3 is moved downward by the electric push rod 2, the fixed plate 8 moves, which in turn moves the rack plate 91 downward, causing the gear 92 to rotate. At the same time, the rotating shaft 93 rotates, which in turn causes the first bevel gear 94 to rotate, thus causing the second bevel gear 95 to rotate, thereby causing the flip plate 102 to flip. Therefore, when the suction hood 3 is lowered for dust collection, the flip plate... 102 can shield the front of the cooling pool 1 to prevent smoke from escaping and improve the purification effect. The top of the transmission structure 9 is provided with a blowing structure 7. The blowing structure 7 includes a folded rod 71 fixedly connected to the left side of the fixed plate 8 and a placement plate 72 set at the bottom of the folded rod 71. Several fans 73 are set inside the placement plate 72, so that they can be raised and lowered at the same time as the suction hood 3, and blow air in the direction of the suction hood 3 through the fans 73, so that water vapor or dust can be sucked in through the suction hood 3. Thus, the fans 73 and the suction hood 3 work together to improve the purification effect. The top of the cooling pool 1 is provided with a shielding structure 10.

[0028] The shielding structure 10 includes a baffle 101 fixedly connected to the top of the cooling pool 1 and a flip plate 102 set on the front side of the cooling pool 1. The flip plate 102 is arc-shaped, which can reduce the scattering of smoke generated when cooling the valve box. At the same time, the arc-shaped setting of the flip plate 102 can guide the air blown out by the fan 73, thereby improving the effect of steam intake.

[0029] A protective cover 12 is fitted on the outer side of the first bevel gear 94 and the second bevel gear 95. The protective cover 12 is fixedly connected to the left side of the cooling pool 1. The protective cover 12 can cover the first bevel gear 94 and the second bevel gear 95 to prevent foreign objects and coolant from entering the meshing part of the first bevel gear 94 and the second bevel gear 95, avoid wear or jamming, and extend the service life of the transmission structure 9.

[0030] Working principle: Before hoisting the valve box to the top of the cooling pool 1 for cooling, start the fan 4 and the fan 73. Then, hoist the valve box to the right side of the cooling pool 1 and move it laterally. As the valve box is lowered into the cooling pool 1, start the electric push rod 2, which moves the fixed plate 8 and the suction hood 3 downwards. As the fixed plate 8 moves downwards, it also moves the folding rod 71 downwards. This allows the suction hood 3 and the fan 73 to move downwards simultaneously, enabling them to work together. As the fixed plate 8 moves, it moves the rack plate 91 downwards, causing the gear 92 to rotate. This, in turn, causes the rotating shaft 93 to rotate. As the rotating shaft 93 rotates, it drives the first... The rotation of bevel gear 94 drives the rotation of second bevel gear 95, which in turn drives the tilting plate 102 to tilt. This allows the tilting plate 102 to shield the front of the cooling pool 1 when the suction hood 3 is lowered to suck up dust, preventing smoke from escaping and improving the purification effect. When the valve box comes into contact with the coolant, the steam generated is greatly reduced by the suction hood 3 and the blowing of the fan 73, thus preventing workers from inhaling large amounts of harmful gases and affecting their health. After long-term use, a large amount of oil fumes are adsorbed on the surface of filter 62. At this time, the connecting sleeve 61 can be rotated to remove it from the connecting pipe 11, so that filter 62 can be cleaned or replaced.
