Description

Technical Field

[0001] This utility model proposes a pneumatic conveying device, which relates to the field of pneumatic conveying devices, and specifically to a double-tube pneumatic conveying device. Background Technology

[0002] The equipment that solves the problems of easy pipe blockage and high wear in traditional pneumatic conveying by using an inner and outer double pipe structure is called a double-pipe pneumatic conveying system. Its core lies in using the double pipe design to optimize airflow distribution and achieve low energy consumption and high density material conveying.

[0003] However, the double-pipe structure is complex. If the inner pipe opening is not designed properly, the range of local airflow disturbance is limited, making it impossible to effectively remove adhesive materials. In addition, the pipe is difficult to disassemble and clean, especially the replacement of the inner pipe components, which requires complete disassembly and high maintenance costs.

[0004] Therefore, those skilled in the art have proposed a double-tube pneumatic conveying device, which improves the structure of the existing double-tube pneumatic conveying device and can adjust the spacing of the inner tube openings according to the needs of use, so as to better convey materials. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-pipe pneumatic conveying device. Instead of the existing nozzles for clearing turbulence directly on the side of the turbulence pipe, it replaces them with nozzles connected to the side wall of the turbulence pipe via corrugated pipes. The distance between the outlet ends of the two turbulence pipes can be adjusted by a rotating shaft extending to the outside of the main pipe. When the main pipe is partially blocked, the local air pressure in the main pipe can be increased by moving the nozzle position, thereby enhancing the turbulence effect.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-pipe pneumatic conveying device, comprising a main pipe and a turbulent flow pipe, wherein the turbulent flow pipe is sleeved inside the main pipe. When local material settling occurs in the main pipe, a turbulent flow effect is formed inside the main pipe through nozzles opened on the side of the turbulent flow pipe, thereby clearing blockages.

[0007] A slide rail is fixed parallel to one side of the turbulence pipe, and a nozzle is slidably arranged inside the slide rail. One end of the nozzle passes through the turbulence pipe and is fixedly connected to it. The nozzle replaces the nozzle opened on the side of the original turbulence pipe. The distance between the outlet ends of the two nozzles can be changed by driving the nozzle to move along the slide rail, thereby changing the local internal pressure of the main pipe and enhancing the turbulence effect.

[0008] A slider is slidably disposed on the inner side of the slide rail, and a rack is fixedly connected to the side of the slider. The nozzle moves along the slide rail driven by the slider, and the slider moves by the engagement of the rack.

[0009] Preferably, a support frame is fixed to the inner wall of the main pipe corresponding to the turbulence pipe, and the slide rail is fixedly connected to the support frame to stabilize the installation position of the turbulence pipe inside the main pipe.

[0010] A corrugated pipe is connected between the nozzle and the turbulence pipe. The corrugated pipe not only ensures the continuous connection between the nozzle and the turbulence pipe, but also allows free movement when the nozzle is adjusted and the angle changes, facilitating adjustment as needed.

[0011] Preferably, a guide strip is fixedly connected to the side of the nozzle, and the slider is slidably connected to the nozzle through the guide strip, so as to ensure that one end of the nozzle is connected to the turbulence tube while it can slide and be positioned along the slide rail.

[0012] A guide sleeve is fixed to the side of the slide rail corresponding to the rack. When the drive structure on the side of the slide rail drives the rack to advance, it ensures the accurate movement trajectory of the slider.

[0013] Preferably, a protrusion is fixedly connected to the side of the slide rail, and a rotating shaft is rotatably provided through the side of the protrusion. The rack is meshed with the rotating shaft, and one end of the rotating shaft passes through the side wall of the main tube and extends to its outer side. The rack in the same group is synchronously controlled to advance and adjust through the end of the rotating shaft extending to the outside of the main tube.

[0014] Preferably, an extension sleeve is slidably sleeved on the side of the nozzle away from the turbulent pipe, so that the nozzle, whose end is fixed to the side wall of the turbulent pipe, can maintain a stable installation distance relative to the inner wall of the main pipe when the installation angle changes.

[0015] A fixing block is fixedly connected to the side of the extension sleeve. The slider is rotatably connected to the extension sleeve through the fixing block. When the slider is driven to move along the slide rail, the angle of the extension sleeve relative to the slider changes through the fixing block. At the same time, the position of the extension sleeve and the slider does not change.

[0016] This utility model discloses a double-tube pneumatic conveying device, which has the following beneficial effects:

[0017] This dual-pipe pneumatic conveying equipment changes the nozzles directly opened on the side of the existing turbulence pipe to nozzles connected by corrugated pipes. Furthermore, a rotating shaft is installed through the side wall of the main pipe to synchronously control the angle deflection of the nozzles in the same group. The distance between the outlet ends of the nozzles in the same group can be adjusted according to the needs of use, so as to change the local turbulence intensity in the pipeline without disassembling the pipeline.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model discloses a double-tube pneumatic conveying device;

[0027] According to the appendix Figure 1 As shown, it includes a main pipe 1 and a turbulent pipe 2. The turbulent pipe 2 is installed inside the main pipe 1. When local material sedimentation occurs in the main pipe 1, turbulence is generated inside the main pipe 1 through the nozzles opened on the side of the turbulent pipe 2, thereby clearing the blockage.

[0028] According to the appendix Figure 2 and attached Figure 3As shown, a slide rail 3 is fixed parallel to one side of the turbulent pipe 2, and a nozzle 4 is slidably arranged inside the slide rail 3. One end of the nozzle 4 passes through the turbulent pipe 2 and is fixedly connected to it. The nozzle 4 replaces the original nozzle on the side of the turbulent pipe 2. The distance between the outlet ends of the two nozzles 4 can be changed by driving the nozzle 4 to move along the slide rail 3, thereby changing the local internal pressure of the main pipe 1 and enhancing the turbulence effect.

[0029] A slider 5 is slidably arranged inside the slide rail 3, and a rack 6 is fixedly connected to the side of the slider 5. The nozzle 4 is driven to move along the slide rail 3 by the slider 5, and the slider 5 is driven to move by the meshing of the rack 6.

[0030] A support frame 7 is fixed on the inner wall of the main pipe 1 corresponding to the turbulent flow pipe 2. The slide rail 3 is fixedly connected to the support frame 7 to stabilize the installation position of the turbulent flow pipe 2 inside the main pipe 1.

[0031] According to the appendix Figure 3 As shown, a bellows 8 is connected between the nozzle 4 and the turbulence pipe 2. The bellows 8 not only ensures the continuous connection between the nozzle 4 and the turbulence pipe 2, but also allows free movement when the nozzle 4 is adjusted and the angle changes, which is convenient for adjustment needs.

[0032] A guide bar 9 is fixedly connected to the side of the nozzle 4. The slider 5 is slidably connected to the nozzle 4 through the guide bar 9, ensuring that one end of the nozzle 4 is connected to the turbulence pipe 2 while it can slide and be positioned along the slide rail 3.

[0033] A guide sleeve 10 is fixed on the side of the slide rail 3 corresponding to the rack 6. When the drive structure on the side of the slide rail 3 drives the rack 6 to advance, it ensures the accurate movement trajectory of the slider 5.

[0034] According to the appendix Figure 4 and attached Figure 5 As shown, a protrusion 11 is fixedly connected to the side of the slide rail 3. A rotating shaft 12 is rotatably mounted through the side of the protrusion 11. The rack 6 is meshed with the rotating shaft 12. One end of the rotating shaft 12 passes through the side wall of the mother tube 1 and extends to its outside. The rotating shaft 12 extends to the outside of the mother tube 1 and synchronously controls the rack 6 in the same group to make advance adjustment.

[0035] An extension sleeve 13 is slidably sleeved on the side of the nozzle 4 away from the turbulent pipe 2, so that the nozzle 4, which is fixed to the side wall of the turbulent pipe 2 at one end, can maintain a stable installation distance relative to the inner wall of the mother pipe 1 when the installation angle changes.

[0036] The extension sleeve 13 is fixedly connected to the side of the fixed block 14. The slider 5 is rotatably connected to the extension sleeve 13 through the fixed block 14. When the slider 5 is driven to move along the slide rail 3, the extension sleeve 13 changes its angle relative to the slider 5 through the fixed block 14. At the same time, the position of the extension sleeve 13 and the slider 5 does not change.

[0037] This dual-pipe pneumatic conveying equipment changes the nozzle directly opened on the side of the existing turbulent pipe 2 to a nozzle 4 connected by a corrugated pipe 8. Furthermore, a rotating shaft 12 is installed through the side wall of the main pipe 1, which can synchronously control the angle deflection of the nozzles 4 in the same group. The distance between the outlet ends of the nozzles 4 in the same group can be adjusted according to the needs of use, so as to change the local turbulence intensity in the pipeline without disassembling the pipeline.
