Description

Technical Field

[0001] This application relates to the field of pipeline technology, and in particular to an easy-to-process ceramic internal bypass pipeline. Background Technology

[0002] Dense phase conveying is a form of pneumatic conveying characterized by low material velocity within the conveying pipeline. It is particularly suitable for materials with low breakage requirements, high abrasiveness, low melting point, and poor stability. Internal bypass technology is a method to solve the problem of easy pipe blockage in dense phase conveying. By adding a bypass pipe inside the conveying pipe, the conveying gas enters the conveying pipeline through the connecting hole on the bypass pipe, appropriately increasing the conveying power of dense phase conveying, thereby effectively solving the problem of pipe blockage in dense phase conveying.

[0003] In existing technologies, in fields such as new energy, fine chemicals, pharmaceuticals, and new materials, certain raw materials, additives, intermediates, and finished products may have requirements such as not being able to contact metals, high abrasiveness, poor stability, high-temperature decomposition, and low breakage rate. Therefore, suitable pipeline technology is needed to provide a dense phase transport carrier. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies in fields such as new energy, fine chemicals, pharmaceuticals, and new materials, where certain raw materials, additives, intermediates, and finished products may have issues such as being unable to contact metals, high abrasiveness, poor stability, high-temperature decomposition, and low breakage rate requirements, necessitating suitable conveying pipeline technology to provide a dense phase conveying carrier. Therefore, this invention proposes an easily machinable ceramic internal bypass conveying pipeline.

[0005] The technical solution for an easily machinable ceramic internal bypass conveying pipe provided in this application is as follows: An easy-to-process ceramic internal bypass conveying pipe includes: The components include a connector, a ceramic gas supply straight pipe section, a ceramic gas supply connecting pipe section, an outer pipe, and an adhesive sealing layer. The ceramic gas supply straight pipe section has a delivery pipe and a gas supply pipe inside, and a positioning hole. The ceramic gas supply connecting pipe section has a delivery pipe and a gas supply pipe inside, and a through hole and a through hole are provided between the gas supply pipe and the delivery pipe. A throttling block is provided between the through hole and the through hole inside the gas supply pipe.

[0006] Furthermore, the ceramic gas supply connecting pipe section is provided with positioning holes.

[0007] Furthermore, the second and first conveying pipes can be in the form of straight pipe sections and bent pipe sections.

[0008] Furthermore, the connector is provided with a positioning device.

[0009] Furthermore, both the second and first conveying pipes are composed of ceramic monomers.

[0010] Furthermore, the ceramic monomer is provided with a positioning rod that is adapted to the positioning hole.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying pipeline of this solution is composed of ceramic units. Ceramic units come in different forms, typically divided into ceramic gas-injection straight pipe sections and ceramic gas-injection connecting pipe sections. Depending on the physicochemical properties of the material, there may be one or more different ceramic gas-injection straight pipe sections and ceramic gas-injection connecting pipe sections in the same conveying pipeline. Their lengths and styles can be different, but it is preferred that they are the same to reduce costs. 2. The throttling block in this scheme serves to block airflow and create airflow disturbance. It is preferably placed between two connecting holes, and its size is determined according to the physical and chemical properties of the conveyed material. 3. The connectors connecting the pipes in this solution have positioning devices, which can take the form of positioning holes, male and female mating, grooves, etc. 4. The ceramic unit inside the bend in this solution is either curved or straight, which has the advantages of low manufacturing difficulty, easy quality control, and low cost. 5. This solution has an adhesive sealing layer between the outer tube and the ceramic unit, which can provide effective support and connection for the ceramic unit, effectively isolate the material from the outer tube, and reduce the manufacturing precision requirements of the ceramic unit.

[0012] In addition to targeted gas replenishment, effective prevention of pipe blockage, increased transmission distance, reduced gas pressure and volume, and balanced transmission speed between different sections of the pipeline, this utility model also has the advantages of effectively preventing material from contacting metal, being wear-resistant, easy to manufacture, and low in cost.

[0017] Reference Figure 3 The outer tube 4 serves to provide support and facilitate manufacturing and installation. The outer tube 4 can be made of metal carbon steel, stainless steel, non-metallic plastic, concrete, fiberglass, etc.

[0018] Reference Figure 3 and Figure 4 The ceramic gas supply connecting pipe section 3 is provided with positioning holes 23 or positioning grooves.

[0019] Reference Figure 7 The two conveying pipes 33 and 22 have straight pipe sections and bent pipe sections. The bends can be assembled at different angles according to the needs of use. One or two types of pipes can be used for conveying according to the actual situation. Generally, ordinary inner-lined circular ceramic pipes can be used for bends.

[0020] Reference Figure 1 and Figure 7 The connector 1 is equipped with a positioning device 6, which can take the form of a positioning hole 23, a male and female mating device, a groove, etc. The figure shows the form of a positioning hole 23, which facilitates accurate alignment with the air supply pipe opening during pipe connection.

[0021] Reference Figure 5 The second conveying pipe 33 and the first conveying pipe 22 are composed of ceramic units 8. The ceramic units 8 have different forms, typically divided into ceramic gas supply straight pipe section 2 and ceramic gas supply connecting pipe section 3. Depending on the physicochemical properties of the material, the same first conveying pipe 22 may have one or more different ceramic gas supply straight pipe sections 2 and ceramic gas supply connecting pipe sections 3. Their lengths and styles can be different, but it is preferred that they are the same to reduce costs.
