Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, and in particular to a telescopic tube type movable casting dust removal hood. Background Technology

[0002] In the field of cast iron manufacturing, lost foam casting technology is widely used in the production of complex castings due to its advantages such as eliminating the need to remove the mold, high dimensional accuracy of castings, and simplified molding process. In this process, a foam casting model is placed in a sand box, and dry sand is filled to fix the model. High-temperature molten iron is then poured into the model cavity. When the molten iron comes into contact with the foam model, the model instantly vaporizes, burns, and generates a large amount of gas. This gas is discharged through the sand box's exhaust system, while the molten iron continuously fills the space occupied by the model. After the molten iron cools and solidifies, the dry sand is poured out to obtain a cast iron part that matches the shape of the model. The entire process does not require mold removal, significantly reducing surface damage and dimensional errors in the casting.

[0003] However, in the existing dust removal process for casting, multiple dust hoods are usually set up because the casting involves multiple stations. However, the more dust hoods there are, the larger the dust collector is needed, which results in a waste of energy. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology mentioned above, and to propose a telescopic tube type movable casting dust removal hood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic tube type movable casting dust hood includes a slide rail support, a hood body is provided below the slide rail support, the hood body is fixedly connected to a steel wire rope, the steel wire rope is slidably connected to a plurality of pulleys, an electric winch is slidably connected to the steel wire rope, the electric winch is provided above the base frame, a track is fixedly connected below the slide rail support, the track is slidably connected to the hood body, a fixing component is installed on the top of the hood body, and a fixing mechanism for fixing elbows is provided on the side of the fixing component.

[0006] The above technical solution further includes: The fixing mechanism includes a housing disposed on the side of the fixing component, a push plate slidably connected to the housing, the push plate being fixedly connected to the pull rod, a pull block being fixedly installed on the side of the pull rod, a spring being fixedly connected to the side of the push plate, and the end of the spring away from the push plate being fixedly connected to the housing.

[0007] A telescopic hose is provided at the end of the elbow away from the cover. The telescopic hose is installed below the slide rail hanger, and the hanger is installed below the slide rail support. A pneumatic valve is installed at the end of the telescopic hose away from the elbow.

[0008] The connection between the elbow and the flexible hose enables a smooth transition of dust from the hood to the pipeline system. Combined with the flexible hose's ability to freely expand and contract as the hood moves, it ensures that the dust transport path remains connected when the hood covers different work positions, preventing dust leakage caused by pipeline pulling or folding. The pneumatic valve allows for flexible control of the dust transport, and closing the pneumatic valve facilitates individual inspection and maintenance of the pipeline system.

[0009] A base frame is installed below the slide rail bracket, and the bottom of the base frame is connected to the ground.

[0010] The base frame provides a stable bottom support for the slide rail bracket, transferring the load of the slide rail, cover, etc. of the device to the ground. This ensures that the slide rail bracket maintains structural stability when bearing the negative pressure of cover movement and dust collection, avoiding equipment deformation or displacement due to insufficient support, and ensuring the overall reliability of the device operation.

[0011] Sand boxes are symmetrically arranged on both sides of the base frame, and a pouring platform is provided on the side of the sand box away from the base frame.

[0012] This layout distributes multiple sand boxes around the base frame. Combined with the movable nature of the cover, it achieves coverage of the pouring stations where multiple sand boxes are located. This adapts to the production mode of alternating pouring at multiple stations in the lost foam casting workshop, improving the adaptability and production efficiency of the equipment. The pouring platform provides an operating base for the sand boxes, and the layout of the pouring operation space and dust removal device are reasonably connected. This ensures that the cover can accurately cover the dust generation area above the sand boxes, guaranteeing the effectiveness of dust capture.

[0013] The end of the elbow furthest from the cover is connected to the dust collector.

[0014] It realizes the final transportation of smoke and dust from the workshop operation area to the dust removal system, so that the smoke and dust collected by the hood can be centrally introduced into the dust collector for filtration through pipe components such as elbows and telescopic hoses, thus achieving a complete process of generating smoke and dust, capturing smoke and dust, and purifying smoke and dust.

[0015] This utility model has the following beneficial effects: In this invention, since only a single movable hood is needed to cover multiple workstations, it is not necessary to configure an independent fume hood and exhaust pipe for each workstation. Therefore, the requirements for the total air pressure and total air volume of the dust collector are greatly reduced, directly reducing the operating load of the dust collector, thereby reducing the power consumption of the equipment during operation and achieving energy saving effect.

[0016] In this invention, the device adopts a multi-station coverage design with a single movable hood. Through the coordinated traction of an electric winch, steel wire rope, and pulleys, the hood moves along the slide rail to cover multiple pouring stations. Compared with the solution of multiple fixed dust collection hoods for multiple stations, this reduces the number of fume hoods. This design concentrates the wind pressure and air volume on the station currently covered by the hood, greatly enhancing the wind pressure and air volume under the hood. This allows the smoke and dust generated during pouring to be quickly captured and guided into the telescopic hose, effectively preventing the smoke and dust from spreading into the workshop environment and significantly improving the smoke exhaust effect.

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.

[0020] Please see Figures 1-4 As shown, this utility model is a telescopic tube type movable casting dust removal hood, including a slide rail bracket 1, a hood body 2 is arranged below the slide rail bracket 1, the hood body 2 is fixedly connected to a steel wire rope 8, the steel wire rope 8 is slidably connected to a plurality of pulleys 19, the steel wire rope 8 is slidably connected to an electric winch 10, the electric winch 10 is arranged above the base frame 20, a track 9 is fixedly connected below the slide rail bracket 1, the track 9 is slidably connected to the hood body 2, a fixing member 13 is installed on the top of the hood body 2, and a fixing mechanism for fixing the elbow 7 is provided on the side of the fixing member 13.

[0021] In one embodiment, the fixing mechanism includes a housing 14 disposed on the side of the fixing member 13, a push plate 15 slidably connected to the housing 14, the push plate 15 being fixedly connected to the pull rod 17, a pull block 16 being fixedly installed on the side of the pull rod 17, a spring 18 being fixedly connected to the side of the push plate 15, and the end of the spring 18 away from the push plate 15 being fixedly connected to the housing 14.

[0022] In one embodiment, for the elbow 7, a telescopic hose 6 is provided at the end of the elbow 7 away from the cover 2. The telescopic hose 6 is installed below the slide rail hanger 5, the hanger 5 is installed below the slide rail bracket 1, and a pneumatic valve 3 is installed at the end of the telescopic hose 6 away from the elbow 7.

[0023] In this embodiment, the connection between the elbow 7 and the telescopic hose 6 enables a smooth transition of dust from the hood 2 to the pipeline system. Combined with the free expansion and contraction of the telescopic hose 6 as the hood 2 moves, it ensures that the dust conveying passage remains connected when the hood 2 covers different work positions, avoiding dust leakage caused by pipeline pulling or folding. The pneumatic valve 3 can flexibly control the on / off of dust conveying, and closing the pneumatic valve 3 facilitates individual inspection and maintenance of the pipeline system.

[0024] In one embodiment, the base frame 20 is installed below the slide rail bracket 1, and the bottom of the base frame 20 is connected to the ground.

[0025] In this embodiment, the base frame 20 provides a stable bottom support for the slide rail bracket 1, transferring the load of the slide rail 4, cover 2, etc. of the device to the ground, ensuring that the slide rail bracket 1 maintains structural stability when bearing the negative pressure of the movement of the cover 2 and the collection of smoke and dust, avoiding equipment deformation or displacement due to insufficient support, and ensuring the overall reliability of the device operation.

[0026] In one embodiment, for the aforementioned base frame 20, sand boxes 12 are symmetrically arranged on both sides of the base frame 20, and a pouring platform 11 is arranged on the side of the sand box 12 away from the base frame 20.

[0027] In this embodiment, this layout distributes multiple sand boxes 12 around the base frame 20. Combined with the movable nature of the cover 2, the cover 2 covers the pouring stations where multiple sand boxes 12 are located. This adapts to the production mode of alternating pouring at multiple stations in the lost foam casting workshop, improves the station adaptability and production efficiency of the device, and provides the pouring platform 11 with the operating basis for the sand boxes 12. This ensures that the pouring operation space and the dust removal device are reasonably connected, and that the cover 2 can accurately cover the dust generation area above the sand boxes 12, thus ensuring the effectiveness of dust capture.

[0028] In one embodiment, for the elbow 7 described above, the end of the elbow 7 away from the cover 2 is connected to the dust collector.

[0029] In this embodiment, the final transportation of smoke and dust from the workshop operation area to the dust removal system is realized, so that the smoke and dust collected by the hood 2 can be centrally introduced into the dust collector for filtration through pipeline components such as elbow 7 and telescopic hose 6, thus achieving a complete process of generating smoke and dust, capturing smoke and dust, and purifying smoke and dust.

[0030] The working principle of the telescopic tube type movable pouring dust hood in this utility model is as follows: after the electric winch 10 is started, the steel wire rope 8 wound on its drum forms a U-shaped transmission path through 4 redirecting pulleys 19. The two ends of the steel wire rope 8 are fixed to the left and right sides of the hood body 2 respectively. When the electric winch 10 rotates forward or backward, the traction force generated by the winding and unwinding of the steel wire rope 8 will drive the hood body 2 along the slide rail 4. The slide rail 4 is fixed and supported by the slide rail bracket 1 to slide left and right, thereby realizing the coverage of multiple pouring stations by the hood body 2.

[0031] When the hood 2 moves to the target pouring position, the pouring platform 11 area where the sand box 12 is located, the hood 2 will cover the pouring area above the sand box 12. At this time, the fumes generated during the pouring operation will form a local negative pressure environment inside the hood 2, and the fumes will be forcibly confined inside the hood 2 to prevent them from spreading to the workshop.

[0032] The smoke and dust inside the hood 2 enters the elbow 7 through the smoke outlet, then passes through the telescopic hose 6, and is suspended at equal intervals on the hanging rail by the hanger 5. It can slide freely with the hood 2 and be transported to the dust removal main pipeline. The pneumatic valve 3 can control the opening and closing of the pipeline, and finally the smoke and dust enter the dust collector.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
