Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a dust collector outlet pipeline connection device. Background Technology

[0002] A dust collector is a device used to collect and treat suspended dust particles in the air. It is widely used in industrial production, workshop operations, and household cleaning. Through a filtration system, it captures and stores dust particles (such as metal dust and chemical dust) generated during the production process. It can also filter harmful substances in the air, such as chemical gases and odors, to provide a cleaner working or living environment, control dust concentration to prevent it from reaching the explosion limit, reduce the risk of dust explosion, and reduce dust damage to production equipment, extend equipment life, and reduce maintenance costs.

[0003] During the use of dust collectors, the pipe connection device at the air outlet is a key component for the effective exhaust of air. Currently, the common air outlet pipe connection structure of dust collectors often has the problem of single function, and most of them can only achieve exhaust through a single path. When it is necessary to perform directional air intake or large-scale decentralized exhaust according to the actual working conditions, the existing devices are difficult to switch flexibly and have poor adaptability. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-8 A dust collector outlet pipe connection device includes a fan 1, a connecting pipe 2 installed at the output end of the fan 1, an installation assembly provided on the outer periphery of the connecting pipe 2, a rectangular box assembly installed on the connecting pipe 2 through the installation assembly, and one end of the air outlet of the connecting pipe 2 extending into the rectangular box assembly.

[0031] The rectangular box assembly has an opening 3 on the side away from the connecting pipe 2, a sleeve 4 is installed on one side of the opening 3, and a shielding component is rotatably installed on one side of the sleeve 4.

[0032] It also includes: air duct 5, which can pass through the sleeve 4 and connect to the air outlet of the connecting pipe 2. By connecting the air duct 5 to the air outlet of the connecting pipe 2, air can be drawn directly out from the air duct 5.

[0033] When in use, this device forms a modular assembly structure with the connecting pipe 2 at the output end of the fan 1, the rectangular box assembly, the sleeve 4, the shielding assembly, and the air duct 5, realizing the multi-path exhaust function of the dust collector's air outlet. When no external air duct 5 is needed, the air can be discharged through the rectangular box assembly; when directional air is required, the air duct 5 can move through the sleeve 4 and connect to the air outlet of the connecting pipe 2 to directly draw out the air, which not only ensures the flexibility of exhaust, but also protects the sleeve 4 through the shielding assembly to prevent impurities from entering when there is no air duct 5 connected.

[0034] Furthermore, the rectangular box assembly includes a box body 6 and a cavity 7 disposed within the inner cavity of the box body 6. The outer periphery of the box body 6 is provided with a plurality of air outlet holes 8, which are connected to the cavity 7. Through the air outlet holes 8, air can be blown out from the connecting pipe 2 and enter the cavity 7 of the box body 6, and then flow out from the air outlet holes 8. The box body 6 and the cavity 7 of the rectangular box assembly, together with the plurality of air outlet holes 8, construct a decentralized exhaust path. After the air is blown out from the connecting pipe 2, it enters the cavity 7 and is then evenly discharged through multiple air outlet holes 8, which increases the exhaust contact area, reduces the local wind speed, and avoids the concentrated impact of wind caused by a single air outlet. It is suitable for scenarios that require large-scale, low-intensity exhaust.

[0035] Furthermore, the mounting assembly includes a flange 16 disposed on the outer periphery of the connecting pipe 2. The flange 16 is connected to one side of the housing 6, and the connecting pipe 2 is connected to the cavity 7. The flange 16 of the mounting assembly provides a stable and detachable connection structure between the connecting pipe 2 and the housing 6. Through the connection function of the flange 16, the connection between the connecting pipe 2 and the cavity 7 of the housing 6 is ensured to be accurately connected. At the same time, it facilitates the later maintenance and replacement of the connecting pipe 2 or the housing 6, thereby improving the assembly convenience and maintenance efficiency of the device.

[0036] Furthermore, the shielding assembly includes a hinged cover 9 rotatably mounted on one side of the sleeve 4 via a torsion spring shaft. The hinged cover 9 is adapted to the sleeve 4. The hinged cover 9 of the shielding assembly is rotatably connected to the sleeve 4 via a torsion spring shaft. When no air duct 5 is inserted, the elastic force of the torsion spring can make the hinged cover 9 fit tightly against the sleeve 4, thereby sealing and shielding the opening 3 of the sleeve 4 and preventing dust and debris from entering the interior of the sleeve 4. When the air duct 5 is inserted, the hinged cover 9 can rotate and open around the shaft without obstructing the access of the air duct 5.

[0037] Furthermore, a protrusion 10 is provided on the side of the hinge cover 9 near the sleeve 4. The protrusion 10 is integrally molded from rubber material. The protrusion 10 is adapted to the inner cavity of the sleeve 4. The protrusion of the hinge cover 9 is adapted to the inner cavity of the sleeve 4, which enhances the sealing effect of the hinge cover 9 on the sleeve 4. When the protrusion is embedded in the inner cavity of the sleeve 4, its outer circumferential surface fits against the inner wall of the inner cavity, reducing gaps and improving the tightness of the cover.

[0038] Furthermore, two insert rods 11 are installed on the outer periphery of the duct 5, and two guide grooves 12 are opened on the inner wall of the inner cavity of the sleeve 4. Each of the two guide grooves 12 has an insertion hole 13. The insertion hole 13 is adapted to the insert rod 11. The insert rod 11 on the outer periphery of the duct 5 is adapted to the insertion hole 13 of the guide groove 12 in the inner cavity of the sleeve 4 to form a positioning and locking structure. When the duct 5 is inserted into the sleeve 4, the insert rod 11 slides along the guide groove 12 and finally embeds into the insertion hole 13, thereby achieving axial fixation between the duct 5 and the sleeve 4, preventing the duct 5 from falling off due to wind pressure or external force during the exhaust process, and ensuring the stability of the duct 5 connection.

[0039] Furthermore, both guide grooves 12 are arc-shaped, and their arc-shaped extension path is adapted to the movement trajectory of the insertion rod 11 when it is inserted into the inner cavity of the sleeve 4. The extension path of the arc-shaped guide groove 12 is adapted to the movement trajectory of the insertion rod 11, providing a smooth guiding effect for the insertion rod 11. During the insertion of the air duct 5, the resistance is smaller when the insertion rod 11 slides along the arc-shaped groove, which can reduce the jamming during insertion. At the same time, the arc-shaped structure can guide the insertion rod 11 to accurately align with the insertion hole 13, improving the assembly efficiency of the air duct 5 and the sleeve 4.

[0040] Furthermore, the air outlet of the connecting pipe 2 near the box 6 is arc-shaped, which is used to guide the air duct 5 when it is inserted. The arc-shaped design of the air outlet of the connecting pipe 2 provides a guiding function for the insertion of the air duct 5. When the end of the air duct 5 approaches the air outlet of the connecting pipe 2, the arc-shaped surface can guide the air duct 5 to enter in the correct direction, avoiding rigid collision or misalignment between the end of the air duct 5 and the connecting pipe 2, and ensuring that the air duct 5 is smoothly connected to the air outlet of the connecting pipe 2.

[0041] Furthermore, the protrusion 10 is hemispherical, and the hemispherical protrusion 10 has a larger contact area with the arc surface of the inner cavity of the sleeve 4, which can form a tighter fit and reduce gaps caused by assembly errors or vibrations.

[0042] Furthermore, the outer periphery of the housing 6 is provided with a plurality of mounting blocks 14, and each of the mounting blocks 14 is provided with a plurality of mounting holes 15 on one side, for bolts to pass through the mounting holes 15 to fix the housing 6 in the corresponding position. The mounting blocks 14 and mounting holes 15 on the outer periphery of the housing 6 provide a convenient way to fix the housing 6. By passing bolts through the mounting holes 15, the housing 6 can be firmly fixed in the corresponding position of the equipment, preventing the device from shifting due to vibration or wind pressure during operation, and ensuring the stability of the overall structure.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
