[0002] Quantitative pulse pneumatic conveying system is often used for conveying powder materials. It has a simple structure, easy operation, low maintenance cost, flexible layout, can be used for horizontal, vertical or inclined conveying, and has a long conveying distance. It has the advantage of being able to load in one place and unload in multiple places. The existing pneumatic conveying system is equipped with pipelines for conveying powder materials. Since the pneumatic conveying system needs to convey the powder to each production station, its conveying line is usually long and is greatly affected by the ambient temperature. For some powder materials with special requirements in the chemical and medical industries, the temperature of the powder materials needs to be strictly controlled during conveying to avoid deterioration or decline of the powder quality due to improper temperature control during the conveying process. Therefore, it is necessary to add insulation to the outside of the conveying pipeline.

[0003] The existing pipeline insulation structure usually simply wraps insulation cotton around the outside of the pipeline to insulate the pipeline.

[0004] However, in actual use, when the pipeline needs to be repaired, the insulation film needs to be disassembled as a whole. Since the insulation film is directly wrapped around the pipeline, it is easy to be damaged during the disassembly process, and it is easy to be damaged and misaligned when reinstalled, affecting the insulation effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example

[0021] Refer to the instruction manual Figure 1-Figure 4 A pipeline insulation structure for a quantitative pulse pneumatic conveying system includes a pipeline 1, two protective shells 3 are provided on the outside of the pipeline 1, and the two protective shells 3 are detachably connected and sleeved on the outside of the pipeline 1. A flexible heat-conducting covering layer 31 is provided on the side of the inner cavity of the protective shell 3 facing the pipeline 1, and a cavity is formed between the flexible heat-conducting covering layer 31 and the protective shell 3. An insulation component for insulating the pipeline 1 is installed inside the cavity. The flexible heat-conducting covering layer 31 is detachably connected to the surface of the pipeline 1. Extension plates 4 are provided on both sides of the protective shell 3, and each two adjacent extension plates 4 are detachably connected by screws;

[0022] Positioning components are provided at both ends of the protective shell 3, and the positioning components include flexible anti-slip pads 32. The flexible anti-slip pads 32 are slidably inserted into the side of the two ends of the protective shell 3 facing the pipeline 1. The flexible anti-slip pads 32 are in contact with the surface of the pipeline 1, and multiple elastic parts are connected between the flexible anti-slip pads 32 and the protective shell 3.

[0023] It should be noted that when the pulse pneumatic force conveys the powder material through the pipeline 1, the protective shell 3 is installed on the outside of the pipeline 1, and the extension plate 4 is connected by screws to connect the two protective shells 3. At the same time, elastic parts are used at both ends of the protective shell 3 to make the flexible anti-slip pads 32 adapt to the outer surface of the pipeline 1 and wrap around the outside of the pipeline 1, so that the two ends of the protective shell 3 are fixed on the outside of the pipeline 1 to prevent the protective shell 3 from shifting, and the insulation component between the protective shell 3 and the flexible heat-conductive covering layer 31 is heated to keep the temperature in the cavity constant, and the flexible heat-conductive covering layer 31 contacts the outer surface of the pipeline 1 to achieve insulation of the pipeline 1, thereby achieving the function of constant temperature of the powder material during powder material transportation, effectively avoiding the deterioration of the material.

[0024] Furthermore, the elastic part includes a fixed column 34, a plurality of fixed columns 34 are arranged along the inner wall of the protective shell 3, the fixed column 34 is fixedly connected to the protective shell 3, the fixed column 34 is slidingly sleeved with a fixed cylinder 33, the fixed cylinder 33 is connected to the flexible heat-conductive covering layer 31, and a first spring is connected between the fixed cylinder 33 and the fixed column 34.

[0025] In the above embodiment, when the protective shell 3 is installed on the outside of the pipeline 1, the flexible anti-slip pad 32 contacts the pipeline 1, and due to the connection between the two protective shells 3, the elastic member is subjected to relative force between the pipeline 1 and the flexible anti-slip pad 32 when tightened. Due to the elasticity of the spring, the two ends of the protective shell 3 adapt to the pipeline 1 through the elastic member and are positioned on the pipeline 1, preventing the protective shell 3 from shifting after being installed on the pipeline 1.

[0026] Furthermore, the insulation component includes a reflective film 312 fixedly arranged on the inner wall of the protective shell 3, and a heating film 311 is fixedly arranged on the side of the flexible heat-conductive covering layer 31 opposite to the reflective film 312. The heating film 311 is used to heat the surface of the pipeline 1 to keep the pipeline 1 at a constant temperature.

[0027] In the above embodiment, the heating film 311 is used to heat the surface of the pipeline 1 to keep the pipeline 1 at a constant temperature, and cooperates with the reflective film 312 to reflect the heat emitted by the heating film 311 and retain it in the inner cavity of the protective shell 3, thereby improving the temperature retention effect.

[0028] Furthermore, a plurality of elastic members are installed between the flexible heat-conducting covering layer 31 and the protective shell 3 , one end of the elastic member is connected to the flexible heat-conducting covering layer 31 , and the other end of the elastic member is connected to the inner wall of the protective shell 3 .

[0029] In the above embodiment, the flexible heat-conductive covering layer 31 is attached to the outside of the pipeline 1 by the elastic member, so that the protective shell 3 is adapted to pipelines 1 of different sizes through the heating film 311, thereby improving the adaptability of the device.

[0030] Furthermore, an exhaust port 5 is provided on the surface of the protective shell 3, and the protective shell 3 is connected to the outside through the exhaust port 5. An exhaust component is provided in the inner cavity of the exhaust port 5, and the exhaust component includes a positioning plate 53. The positioning plate 53 is connected to a spring 54 on the side facing the protective shell 3, and a piston 52 is connected to the end of the spring 54. The exhaust cylinder 51 is clamped on the outside of the piston 52, and the exhaust cylinder 51 is fixedly installed in the inner cavity of the exhaust port 5. A plurality of through holes are opened through the surface of the positioning plate 53.

[0031] In the above embodiment, before installation, the space between the protective shell 3 and the flexible thermally conductive covering layer 31 is filled with gas, and then the protective shell 3 is installed on the pipeline 1. The flexible thermally conductive covering layer 31 is squeezed by the surface of the pipeline 1, causing the air pressure between the protective shell 3 and the flexible thermally conductive covering layer 31 to be too high. The exhaust pipe 51 can be used to discharge excess gas, causing the piston 52 to move upward, and then the piston 52 is automatically reset by the spring 54 to re-seal the space between the protective shell 3 and the flexible thermally conductive covering layer 31, so that the flexible thermally conductive covering layer 31 automatically adapts to the pipeline 1 and fits the surface of the pipeline 1, thereby improving the thermal insulation effect of the surface of the pipeline 1.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the device is in use, pulse pneumatic force conveys powder materials through the pipeline 1, and the extension plates 4 are connected by screws so that the two protective shells 3 are installed on the outside of the pipeline 1. At the same time, elastic parts are used at both ends of the protective shell 3 to make the flexible anti-slip pads 32 adapt to the outer surface of the pipeline 1 and wrap around the outside of the pipeline 1, so that the two ends of the protective shell 3 are fixed on the outside of the pipeline 1 to prevent the protective shell 3 from shifting, and the insulation component between the protective shell 3 and the flexible heat-conductive covering layer 31 is heated to make the temperature in the cavity constant, and the flexible heat-conductive covering layer 31 contacts the outer surface of the pipeline 1 to achieve insulation of the pipeline 1, thereby achieving the function of constant temperature of the powder material during powder material transportation, effectively avoiding the deterioration of the material, and the elastic parts are relatively stressed between the pipeline 1 and the protective shell 3, so that the protective shell 3 can adapt to pipelines 1 of different sizes and be installed on the outside of the pipeline 1, thereby improving the adaptability of the device.

[0033] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
