Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting technology, and more specifically, to a spiral suction cover. Background Technology
[0002] Casting is a process in which metal is melted and poured into a mold to cool and solidify. It is divided into sand casting and special casting. Sand casting has low cost but takes a long time to make molds, while special casting has high precision but high cost.
[0003] In the foundry industry, during a certain intermediate ladle process, sand needs to be poured into the U-shaped gap between the metal shell and the refractory material for insulation. Because the gap is U-shaped, dust is generated when workers pour the sand. Ordinary suction hoods need to have a large air volume to collect the dust, otherwise the dust collection effect is poor. Therefore, U-shaped suction hoods are used. When using a typical U-shaped suction hood, the dust collection pipe needs to be connected to the suction hood pipe first. Generally, the connection is made by inserting one end of the dust collection pipe into the inside of the suction hood pipe, and then connecting it to the suction hood pipe through the outer sleeve of the dust collection pipe. Subsequently, it is fixed by wrapping a sealing rubber ring around the connection between the suction hood pipe and the sleeve. However, because this operation is relatively cumbersome and the rubber ring will break after being stretched for a long time, it needs to be modified and optimized. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral suction cup, comprising a suction cup tube and a suction cup, wherein the suction cup is fixedly disposed below the suction cup tube;
[0006] A fixing frame is fixedly installed on the side of the suction tube. A support column is fixedly installed on one side of the fixing frame. A side plate is fixedly installed at one end of the support column. A threaded rod is rotatably installed on one side of the side plate. One end of the threaded rod passes through the left and right sides of the side plate and is fixedly installed with a protrusion. A movable plate is movably sleeved on the outside of the protrusion. An arc-shaped plate is fixedly installed on one side of the movable plate. The arc-shaped plate is movably sleeved with the support column. An anti-slip sealing pad is fixedly installed on the inside of the arc-shaped plate. A handle is fixedly installed at the other end of the threaded rod. The threaded rod and the side plate are threaded together.
[0007] As a preferred embodiment of this utility model, a connecting frame is fixedly installed on the inner side of the suction tube, an inner tube is fixedly installed on one side of the connecting frame, a wear-resistant pad is fixedly installed on the side of the inner tube, a friction plate is fixedly installed on the side of the wear-resistant pad, and a protective plate is fixedly installed on the side of the friction plate.
[0008] As a preferred technical solution of this utility model, an anti-slip sealing pad II is fixedly installed on one side of the fixing frame, and the anti-slip sealing pad II is fixedly connected to the suction tube.
[0009] As a preferred embodiment of this utility model, the bottom of the suction hood is provided with a suction port, the inside of the suction port is connected to the inside of the suction hood, and a dust suction pipe is movably installed inside the suction hood tube, with one end of the dust suction pipe extending to the top of the suction hood tube.
[0010] As a preferred embodiment of this utility model, a side block is fixedly installed on the side of the suction tube, a spring is fixedly installed on one side inside the side block, a stop plate is fixedly installed on one end of the spring, a handle two is rotatably installed on one side of the side block, a rotating shaft is fixedly installed on one side of the handle two, one end of the rotating shaft extends into the interior of the side block and passes through the left and right sides of the stop plate, a rotating plate is fixedly sleeved on the outer surface of the rotating shaft, one end of the rotating shaft extends from the outside of the suction tube into the interior of the inner tube, a baffle is fixedly installed on the side of the rotating shaft, the side of the baffle is movably connected to the inside of the inner tube, the rotating plate is rotatably connected to the inside of the side block, and the rotating plate is movably connected to the stop plate.
[0011] In a preferred embodiment of this invention, the rotating shaft is movably connected to the suction tube and the connecting frame, and the spring is located on the outer surface of the rotating shaft.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model involves inserting the suction pipe into the suction hood tube and turning the handle to rotate the threaded rod. Since the threaded rod is threadedly connected to the side plate, it causes the threaded rod and the protrusion to move downwards. When the protrusion moves downwards, it causes the moving plate and the arc plate to move downwards, thus bringing the anti-slip sealing pad into contact with the suction pipe. Compared with traditional devices, this device makes the connection between the suction pipe and the suction hood tube more convenient, reduces operation time, and improves operation efficiency.
[0014] 2. This utility model involves placing the suction cup on fireproof material, aiming the suction nozzle at the sand and gravel, and activating the suction device. The sand and gravel enter the interior of the suction cup through the suction nozzle and are guided into the interior of the suction cup tube through the inner tube. The sand and gravel continuously impact the outer side of the inner tube. The outer side of the inner tube is protected by a protective plate, a friction plate, and a wear-resistant pad. Compared with traditional devices, this device protects the outer side of the inner tube through the design of the wear-resistant pad, friction plate, and protective plate, preventing damage to the inner tube after long-term use, thereby reducing the operating cost of the device.
[0015] 3. This utility model sets the suction port at an angle, so it does not obstruct the worker's view or affect the worker's operation; secondly, by opening the suction port near the dust generation point and not opening the dust suction port in other parts, the collected air volume is reduced, saving the power of the enterprise's dust collection system; thirdly, compared with a large dust suction port, the cross-sectional wind speed of the suction port is faster, and its dust collection effect is better for sand and soil dust with a certain speed.

[0025] 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.
[0026] like Figures 1 to 8 As shown, this utility model provides a spiral suction cup, including a suction cup tube 1 and a suction cup 2, with the suction cup 2 fixedly disposed below the suction cup tube 1;
[0027] A fixing frame 4 is fixedly installed on the side of the suction tube 1. A support column 5 is fixedly installed on one side of the fixing frame 4. A side plate 6 is fixedly installed on one end of the support column 5. A threaded rod 7 is rotatably installed on one side of the side plate 6. One end of the threaded rod 7 passes through the left and right sides of the side plate 6 and is fixedly installed with a protrusion 9. A movable plate 10 is movably sleeved on the outside of the protrusion 9. An arc plate 11 is fixedly installed on one side of the movable plate 10. The arc plate 11 is movably sleeved with the support column 5. An anti-slip sealing pad 12 is fixedly installed on the inside of the arc plate 11. A handle 8 is fixedly installed on the other end of the threaded rod 7. The threaded rod 7 and the side plate 6 are threadedly sleeved.
[0028] When the operator uses the device, they first insert one end of the suction pipe 26 into the suction tube 1, and then turn the handle 8. When the handle 8 turns, it drives the threaded rod 7 to rotate. Since the threaded rod 7 and the side plate 6 are threadedly connected, the threaded rod 7 moves downward as it rotates. When the threaded rod 7 moves downward, it drives the protrusion 9 to move downward. When the protrusion 9 moves downward, it drives the moving plate 10 to move downward. When the moving plate 10 moves downward, it drives the arc plate 11 to move downward, thereby driving the anti-slip sealing pad 12 to move downward. When the inner side of the anti-slip sealing pad 12 contacts the suction pipe 26, the operator can stop turning the handle 8.
[0029] By inserting the suction pipe 26 into the suction hood tube 1 and turning the handle 8, the threaded rod 7 is rotated. Since the threaded rod 7 is threadedly connected to the side plate 6, the threaded rod 7 and the protrusion 9 will move downward. When the protrusion 9 moves downward, the moving plate 10 and the arc plate 11 will move downward, so that the anti-slip sealing pad 12 comes into contact with the suction pipe 26. Compared with the traditional device, this device makes the connection between the suction pipe 26 and the suction hood tube 1 more convenient, reduces the operation time, and improves the operation efficiency.
[0030] The suction tube 1 has a connecting frame 15 fixedly installed on its inner side, an inner tube 14 fixedly installed on one side of the connecting frame 15, a wear-resistant pad 23 fixedly installed on the side of the inner tube 14, a friction plate 24 fixedly installed on the side of the wear-resistant pad 23, and a protective plate 25 fixedly installed on the side of the friction plate 24.
[0031] When the staff uses it, they first place the suction hood 2 above the fireproof material, aim the suction nozzle 3 at the sand and gravel, and then start the dust collection device. The sand and gravel will enter the interior of the suction hood 2 through the suction nozzle 3. When the sand and gravel enter the interior of the suction hood 2, they will be guided by the inner tube 14 to move into the interior of the suction hood tube 1. At this time, the sand and gravel will hit and rub against the outer side of the inner tube 14. The protective plate 25, friction plate 24 and wear-resistant pad 23 will protect the outer side of the inner tube 14 to prevent the sand and gravel from contacting the outer side of the inner tube 14.
[0032] By placing the suction hood 2 on fireproof material and aiming the suction nozzle 3 at the sand and gravel, the dust collection device is activated. The sand and gravel enter the interior of the suction hood 2 through the suction nozzle 3 and are guided to the interior of the suction hood tube 1 through the inner tube 14. The sand and gravel will continuously hit the outside of the inner tube 14. The outer side of the inner tube 14 is protected by the protective plate 25, friction plate 24 and wear-resistant pad 23. Compared with the traditional device, this device protects the outer side of the inner tube 14 through the design of the wear-resistant pad 23, friction plate 24 and protective plate 25, avoiding damage to the inner tube 14 after long-term use, thereby reducing the operating cost of the device.
[0033] Among them, an anti-slip sealing pad 2 13 is fixedly installed on one side of the fixing frame 4, and the anti-slip sealing pad 2 13 is fixedly connected to the suction tube 1.
[0034] The design of the anti-slip sealing pad 23 can improve the sealing performance of the dust suction pipe 26 after it is connected to the suction hood pipe 1, thereby improving the working efficiency of the device.
[0035] The suction hood 2 has a suction port 3 at its bottom, and the inside of the suction port 3 is connected to the inside of the suction hood 2. A dust suction pipe 26 is movably installed inside the suction hood tube 1, and one end of the dust suction pipe 26 extends to the top of the suction hood tube 1.
[0036] The design of suction port 3 does not obstruct the worker's view or affect the worker's operation. It reduces the amount of collected air and increases the air speed, making the dust collection more efficient.
[0037] The suction tube 1 has a side block 16 fixedly installed on its side. A spring 20 is fixedly installed on one side inside the side block 16. A stop plate 21 is fixedly installed on one end of the spring 20. A handle 22 is rotatably installed on one side of the side block 16. A rotating shaft 18 is fixedly installed on one side of the handle 22. One end of the rotating shaft 18 extends into the interior of the side block 16 and passes through the left and right sides of the stop plate 21. A rotating plate 17 is fixedly sleeved on the outer surface of the rotating shaft 18. One end of the rotating shaft 18 extends from the outside of the suction tube 1 to the inside of the inner tube 14. A baffle 19 is fixedly installed on the side of the rotating shaft 18. The side of the baffle 19 is movably connected to the inside of the inner tube 14. The rotating plate 17 is rotatably connected to the inside of the side block 16. The rotating plate 17 is movably connected to the stop plate 21.
[0038] By turning the handle 22, the rotating shaft 18 is driven to rotate. When the rotating shaft 18 rotates, it will drive the baffle 19 to rotate, thus controlling the opening and closing of the inner tube 14.
[0039] The rotating shaft 18 is movably connected to the suction tube 1 and the connecting frame 15, and the spring 20 is located on the outer surface of the rotating shaft 18.
[0040] The design of the rotating shaft 18 enables the baffle 19 to rotate when the handle 22 rotates.
[0041] Working principle and usage process of this utility model:
[0042] When the operator uses the device, they first insert one end of the suction pipe 26 into the suction tube 1, and then turn the handle 8. When the handle 8 turns, it drives the threaded rod 7 to rotate. Since the threaded rod 7 and the side plate 6 are threadedly connected, the threaded rod 7 moves downward as it rotates. When the threaded rod 7 moves downward, it drives the protrusion 9 to move downward. When the protrusion 9 moves downward, it drives the moving plate 10 to move downward. When the moving plate 10 moves downward, it drives the arc plate 11 to move downward, thereby driving the anti-slip sealing pad 12 to move downward. When the inner side of the anti-slip sealing pad 12 contacts the suction pipe 26, the operator can stop turning the handle 8.
[0043] When the staff uses it, they first place the suction hood 2 above the fireproof material, aim the suction nozzle 3 at the sand and gravel, and then start the dust collection device. The sand and gravel will enter the interior of the suction hood 2 through the suction nozzle 3. When the sand and gravel enter the interior of the suction hood 2, they will be guided by the inner tube 14 to move into the interior of the suction hood tube 1. At this time, the sand and gravel will hit and rub against the outer side of the inner tube 14. The protective plate 25, friction plate 24 and wear-resistant pad 23 will protect the outer side of the inner tube 14 to prevent the sand and gravel from contacting the outer side of the inner tube 14.
