Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, and more specifically relates to a pipeline docking structure and a mobile dust removal system. Background Art

[0002] With the improvement of national environmental protection requirements, manufacturing enterprises are required to recycle and centrally treat the harmful substances such as smoke and dust generated during the production process that damage the environment. At present, the more common method is to enclose the equipment that generates smoke and dust with a dust hood, and set a vent on the top of the dust hood to suck the smoke, dust and other harmful substances generated during the production process into the ventilation duct, and transport them to the equipment through the ventilation duct for centralized treatment, so as to achieve the standard of qualified emissions.

[0003] The specific settings of the dust hood are divided into fixed and mobile types. Among them, the advantages of the fixed dust hood are simple equipment, small capital investment, and good dust removal effect. It is often used for small and medium-sized production equipment, ventilation duct collection, convenient layout, and material output or output from the side. However, this fixed dust hood also has certain limitations. For example, in some metallurgical, chemical and other industries, when materials need to be loaded or lifted out from the top, this layout cannot meet the needs. At this time, a mobile dust hood is needed. That is, when the material needs to be loaded or lifted out from the top, the dust hood needs to be removed, and when production is required, the dust hood is moved above the production equipment. At this time, it is necessary to re-dock the mobile air duct and the fixed air duct of the dust removal system. In order to ensure the sealing performance after docking, it is often necessary to align and connect the ends of the two air ducts, which increases the difficulty of on-site construction.

[0004] After searching, the patent CN204265037U discloses a dust removal duct docking and disconnecting device for a mobile unloading vehicle. The application includes a preset fixed duct, a mobile duct of the unloading vehicle, a spring, a driving device, a bracket, flange one, and flange two. The preset fixed duct is docked with the mobile duct of the unloading vehicle; the upper end of the preset fixed duct is connected to the main duct, and the lower end is connected to flange one. The preset fixed duct is provided with an electric valve, and the flange one is provided with a soft rubber cushion pad; the upper end of the mobile duct of the unloading vehicle is connected to flange two, and the lower end is connected to the upper end of the telescopic sleeve, flange two is connected to a spring, and the lower end of the telescopic sleeve is connected to the dust hood, and flange two is provided with a soft rubber cushion pad; the dust hood is fixedly connected to the bracket arranged on the unloading vehicle. The application uses a soft rubber cushion pad to ensure the sealing during docking, prevent dust from overflowing, and prevent mechanical damage caused by hard connection.

[0005] For another example, the patent CN219221558U discloses a mechanical sealing device for connecting a mobile air duct. The application includes a fixed air duct, a sliding air duct slidably sleeved in the fixed air duct, a first pair of joints arranged at one end of the fixed air duct, the first pair of joints connected to the sliding air duct, a second pair of joints abutting the first pair of joints, a docking dust suction pipe arranged on the second pair of joints, the docking dust suction pipe connects the sliding air duct and the fixed air duct, and one end of a plurality of tightening devices arranged on the fixed air duct, the other end of the tightening device abuts the first pair of joints, and the tightening device is located on the side of the first pair of joints away from the second pair of joints. The application solves the problem in the prior art that the dust removal effect is poor because the gap at the splicing of the dust removal duct is too large and the sealing performance is too poor.

[0006] Although the above applications can ensure the sealing performance of the pipeline joints, they still require alignment and connection operations at the joints, which is not convenient for rapid construction work on site. Utility Model Content

[0037] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0038] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] The utility model is further described below in conjunction with specific embodiments.

[0040] refer to Figure 1 As shown, a mobile dust removal system of this embodiment includes a mobile air duct 5 and a fixed air duct 6. One end of the mobile air duct 5 is connected to a dust removal cover (not shown in the figure), and the other end is sealed and connected to the fixed air duct 6 through a pipe docking structure.

[0041] At the same time, the mobile air duct 5 needs to be equipped with a horizontal moving mechanism (not shown in the figure), which drives the dust cover and the mobile air duct 5 thereon to move horizontally, that is, to move from the side of the fixed air duct 6, thereby completing the sealed connection between the mobile air duct 5 and the fixed air duct 6.

[0042] It is worth mentioning that the above-mentioned moving mechanism and dust cover are both existing structures. At the same time, the above-mentioned lateral movement refers to the movement perpendicular to Figure 1 Direction of the paper.

[0043] In this embodiment, as a specific implementation of the pipeline docking structure, the pipeline docking structure includes a first connecting pipe 1 and a second connecting pipe 2. One end of the first connecting pipe 1 is used to connect to the mobile air duct 5, and the other end is provided with a first docking port 11; one end of the second connecting pipe 2 is used to connect to the fixed air duct 6, and the other end is provided with a second docking port 21.

[0044] The first docking interface 11 and the second docking interface 21 are arranged front and back, and when the two docking interfaces are moved to an aligned state, an installation gap is left between the two docking interfaces. At the same time, in order to ensure the sealing performance at the two interfaces, a sealing belt 3 is provided at the installation gap. Among them, there are multiple sealing belts 3, one end of the multiple sealing belts 3 is surrounded by a shape matching the first docking interface 11, and the other end is surrounded by a shape matching the second docking interface 21. And one end of the sealing belt 3 is fixedly set on one docking interface, and the other end is overlapped on the other docking interface. Under the action of the negative pressure generated at the installation gap, the sealing belt 3 seals the installation gap.

[0045] In the mobile dust removal system of this embodiment, a pipe docking structure is provided so that an installation gap is left between the two pipes, and strict corresponding operation is not required, thereby facilitating the docking operation between the two pipes. At the same time, through the provision of a sealing belt, when air suction and dust removal are performed, negative pressure is generated at the installation gap, forcing the sealing belt to block the installation gap, thereby achieving a good sealing effect.

[0046] In this embodiment, as an implementation method of the sealing method at the docking interface, the first docking interface 11 and the second docking interface 21 are both square interfaces. At the same time, two sealing strips 3 are provided, each sealing strip 3 is bent to form an L-shaped structure, and the two L-shaped sealing strips 3 are respectively provided on different docking interfaces.

[0047] For the convenience of description, the sealing belt 3 on the first docking port 11 is called the first sealing belt, and the sealing belt 3 on the second docking port 21 is called the second sealing belt. The side of the sealing belt connected to the docking port is the fixed end, the side overlapping the docking port is the free end, and the other two sides are the side ends.

[0048] Specifically, refer to Figure 2 , Figure 3 As shown, the horizontal section of the L-shaped first sealing strip is arranged at the bottom of the first docking port 11, and the vertical section thereof is arranged at one side of the first docking port 11 ( Figure 3 The fixed ends of the first sealing tape are fixed to the corresponding sides of the first docking port 11 by clamps.

[0049] refer to Figure 4 , Figure 5 As shown, the horizontal section of the L-shaped second sealing tape is arranged on the top of the second docking port 21, and the vertical section thereof is arranged on the other side of the second docking port 21 ( Figure 5 The fixed ends of the second sealing tape are fixed to the corresponding sides of the second docking port 21 by clamps.

[0050] It should be noted that the vertical sections of the L-shaped sealing tapes 3 on the two docking ports are arranged away from each other to prevent the sealing tape 3 on the second docking port 21 from hindering the movement of the sealing tape 3 on the first docking port 11 .

[0051] In this embodiment, the square interface is more convenient to connect than the traditional circular interface. At the same time, with the arrangement of the two L-shaped sealing strips 3, only two junctions are formed between the end sides of the entire sealing strip 3, which is conducive to ensuring the sealing effect at the installation gap.

[0052] In order to improve the sealing effect of the end of the sealing belt 3, a stopper 4 is provided at the edge of the first and second docking ports 11 and 21 where the sealing belt 3 is not provided. During sealing, the free end of the sealing belt 3 fits against the stopper 4 to form a surface contact, thereby ensuring the sealing effect.

[0053] In addition, in order to ensure the sealing effect of the two sealing strips 3 at the contact point of the side ends, in this embodiment, the width of one of the side ends of the two adjacent sealing strips 3 is greater than the width of the other, so as to form an overlap portion 31 at the junction of the two. The overlap portion 31 can be tightly attached to the other sealing strip 3 under the action of negative pressure to form a surface contact, thereby improving the sealing effect at this point.

[0054] Specifically in this embodiment, refer to Figure 3 , Figure 5 , Figure 6 As shown, the width of the horizontal section and the vertical section of the first sealing belt is consistent with the length of the corresponding side of the butt joint. The width of the horizontal section and the vertical section of the second sealing belt is longer than the length of the corresponding side of the butt joint. In other words, when the two sealing belts 3 are butt jointed with each other, the two side ends of the first sealing belt are respectively located inside the horizontal section and the vertical section of the second sealing belt, and the side ends of the horizontal section and the vertical section of the second sealing belt extend out of the junction between the two.

[0055] It should be noted that the width of the horizontal section and the vertical section refers to the length of the sealing tape 3 extending along the corresponding side of the butt joint. In other words, the ends of the horizontal section and the vertical section of the second sealing tape extend out of their respective butt joints, and the extended section is the overlapped portion 31 mentioned above.

[0056] At the same time, in order to enable the overlapping portion 31 to be bent after being adsorbed so as to overlap the side wall of another sealing belt 3, the overlapping portion 31 is a free extension of the end of the sealing belt and is not fixed by other components.

[0057] This embodiment also provides a pipeline docking method, which includes the following steps:

[0058] The first connecting pipe 1 and the second connecting pipe 2 are arranged front and back, and when the two connecting pipes are moved to the aligned position, a gap is left between the two docking ports;

[0059] The first docking port 11 moves from one side of the second docking port 21 to the end of the second docking port 21; at this time, the free end of the first sealing belt overlaps the second docking port 21, and the free end of the second sealing belt overlaps the first docking port 11; the side end of the horizontal section of the first sealing belt abuts against the inner wall of the vertical section of the second sealing belt, and the side end of the second sealing vertical section extends outward to form an overlap portion 31; the side end of the vertical section of the first sealing belt abuts against the inner wall of the horizontal section of the second sealing belt, and the side end of the second sealing horizontal section also extends outward to form an overlap portion 31;

[0060] During dust removal by suction, negative pressure is generated in the gap, so that the free end of the sealing belt 3 is tightly attached to the outer wall of the corresponding interface; at the same time, the overlapping part 31 is tightly attached to the side wall of the corresponding sealing belt 3 to complete the sealed connection in the two pipes.

[0061] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
