Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic conveying, and particularly relates to a spherical sealing pipeline for pneumatic conveying. Background Art

[0002] Pneumatic conveying uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipe. Setting the pipe joints into a spherical shape can effectively reduce the friction of granular materials on the pipe wall when moving at high speed.

[0003] At present, a Chinese utility model with the publication number of CN214119253U discloses a pneumatic conveying pipeline that can be quickly spliced, including a first pipeline and a second pipeline, the bottom of the first pipeline is integrally formed with a first flange, the top of the second pipeline is integrally formed with a second flange, both sides of the first flange and the second flange are clamped with a holder, the bottom of the inner cavity of the holder is provided with a through groove, and the inner cavity of the through groove is provided with a clamping mechanism. The utility model can push the movable seat through the cooperation of the handle and the movable rod, and can fix and limit the positioning rod through the cooperation of the clamping groove and the limiting block, so that the first flange and the second flange can be quickly spliced, and the cooperation of the spring can provide elastic rebound to the movable seat, which speeds up the splicing speed of the movable seat to the positioning rod, reduces the labor intensity of the user, and solves the problem that the traditional pneumatic conveying pipeline cannot quickly splice the pipeline.

[0004] Since the existing spherical sealing pipe cannot adjust the pipe joint, in the actual application of pneumatic conveying, the pipe needs to be connected to pneumatic conveying equipment in different directions. The spherical sealing pipe can only be re-cut and welded according to the joint direction of the pneumatic conveying equipment, so the actual installation is more troublesome. In addition, the length of the spherical sealing pipe is fixed. When the length between the joint of the pneumatic conveying equipment and the spherical sealing pipe is too much or insufficient, the length of the spherical sealing pipe cannot be adjusted. Therefore, the only way is to cut off the excess pipe or weld a pipe of appropriate length, which is less practical. Utility Model Content

[0005] The utility model aims to provide a spherical sealing pipe for pneumatic conveying, which has the advantages of facilitating the improvement of the joint direction and length of the spherical sealing pipe and facilitating the function of connecting with pneumatic conveying equipment.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a spherical sealed pipe for pneumatic conveying, including a spherical joint, a through groove is opened on the top of the spherical joint, a first pipe is slidably connected to one side of the top of the spherical joint through the through groove, a second pipe is fixedly connected to the bottom of the spherical joint, a sliding groove is opened inside the inner wall of the spherical joint, and a sealing plate slidably connected to the sliding groove is welded to one end of the first pipe close to the spherical joint.

[0007] By adopting the above technical solution, the first pipe is moved to slide on the surface of the through groove, and the rest of the through groove is sealed with a sealing plate to prevent air leakage. Thus, the angle of the spherical sealing pipe can be adjusted to facilitate communication with the interfaces of pneumatic conveying equipment in different directions; by moving the ring gear to mesh with the gear, the screws on both sides are driven to rotate and engage with the telescopic pipe by thread, so that the telescopic pipe slides back and forth on the surface of the spherical joint and the first pipe respectively. Thus, the length of the spherical sealing pipe can be adjusted to improve practicality.

[0008] The utility model is further configured as follows: a telescopic pipe is slidably sleeved on one end of the surface of the first pipe and the second pipe away from the spherical joint, a fixed plate is fixedly sleeved on the surface of the first pipe and the second pipe, both sides of the fixed plate close to one end of the telescopic pipe are rotatably connected with a screw threadedly connected to the telescopic pipe, a gear is fixedly sleeved on one end of the screw close to the fixed plate, a ring gear meshing with the gear is slidably connected inside the fixed plate, and a groove is provided on one side of the surface of the fixed plate.

[0009] By adopting the above technical solution, the length of the spherical sealing pipeline can be adjusted to connect with the interface of the pneumatic conveying equipment, thereby improving practicality.

[0010] The utility model is further configured as follows: the surface of the ring gear is provided with anti-slip grooves.

[0011] The above technical solution is adopted to increase the friction force, making it easier to drive the ring gear to rotate.

[0012] The utility model is further configured as follows: the ends of the first pipeline and the second pipeline away from the spherical joint are both provided with connecting flanges fixedly sleeved with the telescopic pipeline.

[0013] The adoption of the technical solution facilitates the sealing connection between the spherical sealing pipe and the structure of the pneumatic conveying equipment.

[0014] The utility model is further configured as follows: one end of the screw rod away from the fixed plate is fixedly connected with a limiting piece clamped with the telescopic pipe.

[0015] By adopting the above technical solution, the maximum extension sliding distance of the telescopic pipe is limited to prevent it from sliding off the surface of the screw rod.

[0016] The utility model is further configured as follows: the first pipe and the second pipe have their surfaces at one end away from the spherical joint fixedly sleeved with a first sealing ring slidably connected to the telescopic pipe, and the sliding groove has its interior close to the through groove fixedly connected with a second sealing ring slidably sleeved with the sealing plate.

[0017] The above technical solution is adopted to ensure the sealing of the spherical sealing pipeline and prevent gas and material from leaking out.

[0018] The utility model is further configured as follows: a ball bearing which is rotatably connected to the ring gear is provided inside the fixed disk.

[0019] By adopting the above technical solution, the friction force of the ring gear sliding inside the fixed plate is reduced, and the sliding stability is improved.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. Move the first pipe to slide on the surface of the through groove, and use the sealing plate to seal the rest of the through groove to prevent air leakage. Thus, the angle of the spherical sealing pipe can be adjusted to facilitate connection with the pneumatic conveying equipment interface in different directions;

[0022] 2. By turning the ring gear to mesh with the gear, the screws on both sides are driven to rotate and engage with the telescopic pipes, so that the telescopic pipes can slide back and forth on the surface of the spherical joint and the first pipe respectively. In this way, the length of the spherical sealing pipe can be adjusted to improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS
