[0002] Elbows are essential basic pipe fittings in industrial and building piping systems. Their main function is to allow for flexible changes in pipe direction to adapt to complex spatial layouts and system design requirements. Based on different manufacturing processes, common elbows can be divided into seamless elbows and welded elbows, among others.

[0003] By manually or mechanically turning the handle, the steel wire extends along the pipe, hooks the blockage with the head structure, and then pulls it out in the opposite direction, or by rotating and breaking up the blockage, the pipe can be cleared.

[0004] While the aforementioned technologies have achieved the goal of unblocking pipelines, they are only suitable for pipelines containing powdery media. When internal adhesion and blockage occur, traditional steel wire pipeline unblocking tools are unable to break up the adhered fine powder. Therefore, a powder pneumatic conveying pipeline elbow anti-accumulation unblocking device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a powder pneumatic conveying pipeline elbow anti-accumulation and unblocking device, which aims to solve the problem that traditional steel wire pipe unblocking tools are difficult to break up the fine powder when internal adhesion and blockage occur in pipelines containing powdery media.

[0014] As a further description of the above technical solution:

[0015] The grip ring is provided in two sets, and the two sets of grip rings are distributed in a mirror image along the central axis of the fixed column.

[0016] As a further description of the above technical solution:

[0017] The scraper head disassembly assembly includes a scraper head, the front end of which has a hole, and the rear wall of the scraper head is fixedly connected to an inner threaded sleeve, the inner wall of which is threadedly connected to an outer threaded sleeve.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-3 An embodiment of this utility model provides a powder pneumatic conveying pipeline elbow anti-accumulation and unblocking device, including a disc 1, a connecting block 2 fixedly connected to the rear wall of the disc 1, the connecting block 2 and the disc 1 are integrally formed and there is no obvious seam at the connection, and the structural strength is excellent, a fixing column 3 is fixedly connected to the rear wall of the connecting block 2, a gripping ring 4 is fixedly connected to the outer wall of the fixing column 3, a steel wire sleeve 5 is fixedly connected to the rear wall of the fixing column 3, the steel wire sleeve 5 and the fixing column 3 are coaxially arranged and their center lines are completely coincident to ensure balanced force, a scraping head disassembly assembly 6 is provided on the rear wall of the steel wire sleeve 5, and an air compression assembly 7 is provided inside the fixing column 3;

[0033] The air compression assembly 7 includes a sealing ring 71, which is made of wear-resistant nitrile rubber and has good sealing performance and anti-aging properties. A crossbar 73 is slidably connected inside the sealing ring 71. The crossbar 73 passes through the central hole of the sealing ring 71 along the axial direction and slides without jamming. A push block 72 is fixedly connected to the rear wall of the crossbar 73, and a piston head 74 is fixedly connected to the front end of the crossbar 73. The piston head 74 is coaxially fixed with the crossbar 73, and the connection surface is reinforced with glue. The airtightness between the crossbar 73 and the opening is maintained by the sealing ring 71. The piston cover 76 is threadedly connected to the sleeve 75 and can be opened for internal maintenance or cleaning. The sleeve 75 is fixedly connected to the top of the connecting block 2, and the piston cover 76 is threadedly connected to the inside of the sleeve 75. The piston cover 76 and the internal thread of the sleeve 75 fit tightly and have a reliable sealing effect. The inside of the disc 1 has an opening, and the outer wall of the sealing ring 71 is fixedly connected to the inside of the opening. When encountering adhered or accumulated powder, the air compression assembly 7 can be operated to clear the blockage: push the crossbar 73 forward, and the crossbar 73 drives the piston head 74 at its front end to slide forward in the wire sleeve 5 to compress air. The compressed air is ejected forward through the opening inside the disc 1, forming an airflow that impacts and loosens the blocked or accumulated powder in front.

[0034] Reference Figures 2-4The outer wall of the piston head 74 is fitted to the inner wall of the wire sleeve 5. The piston head 74 and the inner wall of the wire sleeve 5 are tightly fitted and form a sealed sliding fit structure with low sliding resistance. The outer wall of the crossbar 73 slides inside the connecting block 2, the fixed column 3, and the wire sleeve 5. Two sets of grip rings 4 are provided. The two sets of grip rings 4 have the same structural dimensions and are symmetrically distributed on both sides of the fixed column 3 for easy two-hand gripping and operation. The two sets of grip rings 4 are mirror-distributed along the central axis of the fixed column 3. The scraper head disassembly assembly 6 includes a scraper head 61. The scraper head 61 is a conical structure made of hard alloy material. The head is sharp and easy to scrape off accumulated material. The front end of the scraper head 61 has a hole 62. The hole 62 is completely along the front and rear end faces of the scraper head 61. The scraper head 61 is fully penetrating, ensuring smooth airflow. An inner threaded sleeve 63 is fixedly connected to the rear wall of the scraper head 61. An outer threaded sleeve 64 is threadedly connected to the inner wall of the inner threaded sleeve 63. The thread specifications of the outer threaded sleeve 64 and the inner threaded sleeve 63 are perfectly matched, ensuring a secure threaded connection. The inner wall of the outer threaded sleeve 64 is fixedly connected to the outer wall of the wire sleeve 5. Multiple sets of holes 62 are provided, arranged in a ring along the central axis of the scraper head 61. The scraper head 61 is threadedly connected to the outer threaded sleeve 64 fixed to the outer wall of the wire sleeve 5 via its rear inner threaded sleeve 63. This structure allows the scraper head 61 to be replaced according to wear or different operating conditions. A rotating device uses the scraper head 61 to scrape away accumulated material from the pipe wall. At the same time, when compressed air pushes the piston head 74, the airflow will also blow forward through multiple sets of holes 62 distributed in a ring along the central axis of the scraper head 61, which will help to disperse the scraped powder and prevent the holes 62 from being blocked, thereby achieving efficient unblocking and cleaning.

[0035] Working Principle: During use, when encountering adhered or accumulated powder, the air compression assembly 7 can be operated to clear the blockage: Pushing the crossbar 73 forward causes the piston head 74 at its front end to slide forward within the wire sleeve 5, compressing air. The compressed air is ejected forward through an opening inside the disc 1, forming an airflow that impacts and loosens the blocked or accumulated powder. A sealing ring 71 maintains airtightness between the crossbar 73 and the opening. The piston cover 76 is threaded onto the sleeve 75 and can be opened for internal maintenance or cleaning. The scraper head 61 is threadedly connected to the outer threaded sleeve 64 fixed to the outer wall of the wire sleeve 5 via its rear inner threaded sleeve 63. This structure allows the scraper head 61 to be replaced according to wear or different working conditions. A rotating device uses the scraper head 61 to scrape away accumulated material from the pipe wall. At the same time, when compressed air pushes the piston head 74, the airflow will also blow forward through multiple sets of holes 62 distributed in a ring along the central axis of the scraper head 61, which will help to disperse the scraped powder and prevent the holes 62 from being blocked, thereby achieving efficient unblocking and cleaning.
