Description

Technical Field

[0001] This utility model relates to the field of transmission pipeline technology, specifically a transmission pipeline that uses an air classifier to separate material particle sizes. Background Technology

[0002] The transmission pipe of an air classifier is the airflow channel connecting the classifier main unit and supporting equipment. It adopts a sealed and wear-resistant design and transports the mixture of material and airflow under negative or positive pressure. Its structure is usually streamlined to avoid turbulence and material deposition, and it uses materials such as stainless steel, ceramic lining, or engineering plastics to adapt to the characteristics of different materials.

[0003] Traditional air classifier transfer pipes are typically customized according to specific equipment layouts and process requirements, with fixed pipe lengths. Assembly usually relies on welding or other methods, which is not only complex and time-consuming to install, but also makes it difficult to flexibly add or remove pipe units according to actual needs, resulting in difficult adjustments and high costs. Therefore, we propose a transfer pipe system that utilizes an air classifier to separate material particle sizes. Utility Model Content

[0004] The purpose of this invention is to provide a transmission pipeline for separating material particle size using an air classifier, in order to solve the problems mentioned in the background art. Traditional air classifier transmission pipelines are usually customized according to specific equipment layout and process requirements, and the pipeline length is fixed. During assembly, they are generally connected by welding or other methods. This method is not only complicated to install, but also consumes manpower and time. It is also difficult to flexibly add or remove pipeline units according to actual needs, and the adjustment is difficult and costly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transmission pipe for separating material particle size using an air classifier, comprising: an air classifier body, a first metal hose fixedly connected to the right side wall of the air classifier body, a second metal hose placed on the right side of the first metal hose, quick-release mechanisms for quick installation and disassembly of the first and second metal hoses on their outer walls, and a splicing mechanism for installing a curved pipe on one side of the second metal hose.

[0006] Preferably, the quick-release mechanism includes a first retaining ring disposed on the outer wall of the first metal hose and the second metal hose, a fixing rod fixedly connected to the rear end of the first retaining ring, a second retaining ring rotatably connected to the front end of the fixing rod, a bolt fixedly connected between the first retaining ring and the fixing rod, and a wing nut threaded onto the outer wall of the bolt.

[0007] Preferably, an inner frame is fixedly sleeved on the outer wall of the first metal hose and the second metal hose, and a sealing ring is fixedly sleeved on the outer wall of the inner frame.

[0008] Preferably, the splicing mechanism includes a connecting pipe fixedly connected to the right side of the second metal flexible hose, the inner wall of the connecting pipe is provided with a first thread, and a sealing gasket is provided inside the connecting pipe.

[0009] Preferably, a splicing pipe is placed on the right side of the connecting pipe, the inner wall of the splicing pipe is provided with a second thread, and the splicing pipe is installed on the right side of the second metal hose through the second thread.

[0010] Preferably, the outer walls of the first metal hose, the second metal hose, and the splicing pipe are all fixedly fitted with multiple reinforcing rings, and all three are made of stainless steel. The splicing pipe is arranged in an "L" shape.

[0011] This utility model has at least the following beneficial effects:

[0012] (1) The quick-release mechanism enables the immediate fixing and separation of the pipeline through the fast locking structure, eliminating the need for cumbersome welding operations. When the inner wall of the pipeline is worn and needs to be replaced, when blockages occur and need to be cleaned, or when a pipeline of a different diameter needs to be replaced to adapt to new materials, disassembly and assembly can be completed in a short time, greatly reducing downtime maintenance time. Especially for continuous production lines, it can significantly reduce production interruption losses caused by equipment maintenance.

[0013] (2) The transmission pipeline is made of stainless steel flexible metal hose, which has good flexibility and can be bent and twisted at will. It can easily adapt to the complex spatial layout of the air classifier transmission system, such as bypassing equipment obstacles and realizing multi-angle connections. Compared with the fixed direction restriction of rigid pipeline, it can flexibly adjust the transmission path, reduce the difficulty of spatial adaptation during installation, especially in scenarios where the production line layout needs to be frequently adjusted, which can reduce the workload and cost of pipeline modification.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a transmission pipe for separating material particle size using an air classifier, comprising: an air classifier body 1, a first metal hose 2 fixedly connected to the right side wall of the air classifier body 1, a second metal hose 3 placed on the right side of the first metal hose 2, a quick-release mechanism 4 for quick installation and disassembly of the first metal hose 2 and the second metal hose 3, and a splicing mechanism 5 for installing a curved pipe on one side of the second metal hose 3.

[0020] The quick-release mechanism 4 includes a first retaining ring 41 disposed on the outer wall of the first metal hose 2 and the second metal hose 3. A fixing rod 42 is fixedly connected to the rear end of the first retaining ring 41, and a second retaining ring 43 is rotatably connected to the front end of the fixing rod 42. A bolt 44 is fixedly connected between the first retaining ring 41 and the fixing rod 42. A wing nut 45 is threaded onto the outer wall of the bolt 44. An inner frame 46 is fixedly sleeved on the outer wall of the first metal hose 2 and the second metal hose 3. A sealing ring 47 is fixedly sleeved on the outer wall of the inner frame 46. When installing the first metal flexible hose 2 and the second metal flexible hose 3, the operator aligns the two hoses, places the quick-release mechanism 4 at the pipe connection, and rotates the second retaining ring 43. With the first retaining ring 41 at the upper end of the pipe and the second retaining ring 43 at the lower end, the pipe is enclosed. At this time, the inner frame 46 and the sealing ring 47 are also fixed at the pipe connection. The sealing ring 47 acts as a seal, filling any small gaps in the pipe connection. Then, rotating the wing nut 45 locks the two retaining rings, thus securing the pipe. To disassemble, the wing nut 45 is rotated in the opposite direction to loosen the two retaining rings and detach them from the pipe, making it easy to remove. The quick-release mechanism 4 enables immediate fixing and separation of the pipe through a rapid locking structure, eliminating the need for cumbersome welding operations. When the inner wall of the pipe is worn and needs to be replaced, when blockages occur and need to be cleared, or when pipes of different diameters need to be replaced to adapt to new materials, disassembly and assembly can be completed in a short time, greatly reducing downtime for maintenance. Especially for continuous production lines, it can significantly reduce production interruption losses caused by equipment maintenance.

[0021] The splicing mechanism 5 includes a connecting pipe 51 fixedly connected to the right side of the second metal flexible hose 3. The inner wall of the connecting pipe 51 has a first thread 52, and a sealing gasket 53 is installed inside the connecting pipe 51. A splicing pipe 54 is placed on the right side of the connecting pipe 51, and the inner wall of the splicing pipe 54 has a second thread 55. The splicing pipe 54 is installed on the right side of the second metal flexible hose 3 via the second thread 55. When it is necessary to install or disassemble the curved pipe, the operator aligns the splicing pipe 54 with the connecting pipe 51, and with the first thread 52 and the second thread 55 engaging, rotates and tightens the splicing pipe 54 to install it onto the second metal flexible hose 3.

[0022] The outer walls of the first metal flexible hose 2, the second metal flexible hose 3, and the splicing pipe 54 are all fixedly fitted with multiple reinforcing rings 6, and all three are made of stainless steel. The splicing pipe 54 is arranged in an "L" shape. The transmission pipeline uses stainless steel metal flexible hoses, which have good flexibility and can be bent and twisted at will, easily adapting to the complex spatial layout of the air classifier transmission system, such as bypassing equipment obstacles and achieving multi-angle connections. Compared with the fixed routing limitations of rigid pipelines, it can flexibly adjust the transmission path, reducing the difficulty of spatial adaptation during installation. Especially in scenarios where the production line layout needs frequent adjustments, it can reduce the workload and cost of pipeline modification.

[0023] Working principle: When installing the first metal flexible hose 2 and the second metal flexible hose 3, the operator aligns the two hoses, places the quick-release mechanism 4 at the pipe connection, and rotates the second retaining ring 43. The first retaining ring 41 is at the upper end of the pipe, and the second retaining ring 43 is at the lower end, thus encasing the pipe. At this time, the inner frame 46 and the sealing ring 47 are also fixed at the pipe connection. The sealing ring 47 acts as a seal, filling any small gaps in the pipe connection. Then, rotating the wing nut 45 locks the two retaining rings, thus fixing the pipe in place. To disassemble, rotate the wing nut 45 in the opposite direction. The two retaining rings are loosened and disengaged from the pipe, making it easy to disassemble the pipe. When it is necessary to install and disassemble the pipe with bends, the operator aligns the splice pipe 54 with the connecting pipe 51, and with the first thread 52 and the second thread 55 working together, the splice pipe 54 is rotated and tightened, thus installing the splice pipe 54 onto the second metal hose 3. The bend of the metal hose is a high-risk area for material erosion and wear. With the threaded connection, when the bend section is worn or damaged, only the bend hose needs to be replaced, without replacing the entire transmission pipe. This avoids the waste of undamaged parts and greatly reduces the cost of spare parts procurement and replacement.
