Description

Technical Field

[0001] This application relates to the field of pipeline technology, and in particular to a ceramic pipeline assembly with an internal bypass. 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 utility model proposes a ceramic pipeline combination ceramic internal bypass conveying pipeline.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ceramic pipe assembly with an internal bypass conveying pipe includes: a connector, a ceramic material conveying pipe section, a ceramic gas replenishment straight pipe section, a ceramic gas replenishment connecting pipe section, connecting bolts, a throttling bolt, an outer pipe, and an adhesive sealing layer. The ceramic material conveying pipe section has bolt holes inside, the ceramic gas replenishment connecting pipe section has threaded holes inside, and a positioning device is fixedly installed on the connector.

[0006] Preferably, the ceramic material conveying pipe section is connected and fixed to the ceramic gas supply straight pipe section and the ceramic gas supply connecting pipe section using connecting bolts.

[0007] Preferably, the ceramic gas supply connecting pipe section is provided with two connecting holes, and the throttling bolt hole is located between the two connecting holes.

[0008] Preferably, the ceramic material conveying pipe section has straight pipe sections and bent pipe sections, and the bent pipe sections are spliced ​​together at different angles according to the needs of use.

[0009] Preferably, a positioner is fixedly installed on the connector.

[0010] Preferably, the ceramic material conveying pipe section, the ceramic gas supply straight pipe section, and the outer pipe are fixedly connected to the adhesive sealing layer.

[0011] The beneficial effects of the ceramic pipe combination ceramic internal bypass conveying pipe in this utility model are as follows: The complex internal bypass pipe structure is broken down into a simple perforated ceramic round tube unit, which is easy to manufacture, reliable in quality, and low in cost. Different sizes of ceramic round tubes can be spliced ​​together according to the actual needs of conveying different materials. The opening position is easy to adjust and highly flexible. The pipes are equipped with positioning devices, making connection convenient and intuitive; There is an adhesive sealing layer between the outer tube and the ceramic unit, which can effectively isolate the material from the outer tube and at the same time reduce the manufacturing precision requirements of the ceramic unit. The ceramic gas supply connecting pipe section has two connecting holes, and the throttling bolt hole is located between the two holes. The throttling bolt is screwed in a certain distance to achieve the throttling effect. The throttling size is controlled by the screwing length of the throttling bolt, which is beneficial to the stability of dense phase transport and enhances the gas supply effect.

[0012] This invention can effectively prevent pipe blockage, increase transmission distance, reduce gas pressure and volume, balance the transmission speed between different sections of the pipeline, and also effectively prevent materials from contacting metal. It is wear-resistant, easy to manufacture, and has a long service life. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0016] Reference Figures 1-5 A ceramic pipe assembly with an internal bypass conveying pipe, comprising: The components include connector 1, ceramic material conveying pipe section 2, ceramic air supply straight pipe section 3, ceramic air supply connecting pipe section 4, connecting bolt 5, throttling bolt 6, outer pipe 7, and adhesive sealing layer 8. Ceramic material conveying pipe section 2 has bolt holes 21 inside, and ceramic air supply connecting pipe section 4 has threaded holes 41 inside. A positioning device 9 is fixedly installed on connector 1. Both ceramic material conveying pipe section 2 and ceramic air supply straight pipe section 3 are composed of perforated circular ceramic pipes fixed with bolts. Circular ceramic pipes, due to their uniform wall thickness and regular shape, have higher processing quality, ceramic density, uniformity, wear resistance, and surface roughness than complex-shaped ceramic parts, resulting in a high yield rate. The diameter, length, and perforation position of ceramic material conveying pipe section 2 and ceramic air supply straight pipe section 3 can be freely combined according to the physicochemical properties of the material, offering high flexibility. Ceramic air supply straight pipe section 3 comprises ceramic material conveying pipe section 2, ceramic air supply straight pipe section 3, and connecting bolt 5.

[0017] In this embodiment, the ceramic material conveying pipe section 2 is connected and fixed with the ceramic gas supply straight pipe section 3 and the ceramic gas supply connecting pipe section 4 using connecting bolts 5. The throttling effect can be easily adjusted by adjusting the screw-in length of the throttling bolt 6. There is no need to adjust the mold or re-fire the ceramic pipe section. The ceramic material conveying pipe sections 2 are connected with ceramic bolts, or they can be connected with special ceramic connectors.

[0018] In this embodiment, the ceramic gas supply connecting pipe section 4 is provided with two connecting holes 42, and the throttling bolt hole 21 is located between the two connecting holes 42. The throttling bolt 6 is screwed in a certain distance to achieve the throttling effect. The throttling size is controlled by the screwing length of the throttling bolt 6. The ceramic gas supply connecting pipe section 2 consists of ceramic material conveying pipe section 2, ceramic gas supply connecting pipe section 4, connecting bolt 5, and throttling bolt 6. The ceramic air supply connecting pipe section 4 has a connecting port, which can be one or more, and the sizes can be equal or unequal. Preferably, there are two ports of unequal size, and the size is determined according to the physical and chemical properties of the conveyed material. The throttling bolt 6 is used to block the airflow and create airflow disturbance. It is preferably placed between the two connecting holes 42, and its screw-in length is determined according to the physical and chemical properties of the conveyed material.

[0019] In this embodiment, the ceramic bypass ceramic material conveying pipe section 2 has straight pipe sections and bent pipe sections. The bent pipe sections can be spliced ​​into different angles according to the needs of use. One type 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 bent pipes). The ceramic unit inside the bent pipe is curved or straight. The figure shows the straight pipe splicing form. The advantages are low manufacturing difficulty, easy quality control, and low cost.

[0020] In this embodiment, a positioner is fixedly installed on the connector 1 of the ceramic internal bypass ceramic material conveying pipe section 2 to facilitate accurate docking with the port of the ceramic gas supply connecting pipe section 4 during pipe connection.

[0021] In this embodiment, the ceramic material conveying pipe section 2, the ceramic gas supply straight pipe section 3, and the outer pipe 7 are fixedly connected to the adhesive sealing layer 8. The outer pipe 7 serves to provide support and facilitate manufacturing and installation. The material of the outer pipe 7 can be metal carbon steel, stainless steel, non-metallic plastic, concrete, fiberglass, etc. There is an adhesive sealing layer 8 between the outer tube 7 and the ceramic material conveying pipe section, which can provide effective support and connection for the ceramic unit, effectively isolate the material from the outer tube 7, and reduce the manufacturing precision requirements of the ceramic unit. The adhesive sealing layer 8 can be an organic adhesive, an inorganic adhesive, or preferably a ceramic-specific adhesive. The ceramic monomer material can be alumina, zirconium oxide, magnesium oxide, silicon dioxide, etc., with alumina being preferred; The manufacturing process of ceramic monomers can include isostatic pressing, hot pressing, dry pressing, slip casting, injection, etc., with isostatic pressing being the preferred method. The forming methods for holes on ceramic monomers can be mold forming, pre-sintering blank drilling forming, or post-sintering machining forming, with pre-sintering blank drilling forming being the preferred method.

[0022] In this embodiment, the ceramic material conveying pipe section 2 is connected and fixed to the ceramic gas replenishment straight pipe section 3 and the ceramic gas replenishment connecting pipe section 4 using connecting bolts 5. During the connection process, the positioning device 9 fixed on the connector 1 plays a key role. The positioning device 9 can accurately align with the pipe opening of the ceramic gas replenishment connecting pipe section 4, ensuring that the connection between each pipe section is accurate and error-free, guaranteeing the integrity and sealing of the pipeline system, and laying the foundation for stable material conveying. The ceramic gas replenishment connecting pipe section 4 is provided with two connecting holes 42, the function of which is to replenish gas to the pipeline system to maintain the gas content inside the pipeline. Pressure balance ensures the smooth flow of materials during transportation. When transporting ceramic materials that are prone to blockage or have specific requirements for the transportation environment, air replenishment can prevent the material from accumulating in the pipeline and improve transportation efficiency. The ceramic air replenishment connecting pipe section 4 has connecting ports, which can be one or more, of equal or unequal size, preferably two of unequal size, the size of which is determined according to the physical and chemical properties of the transported material. The throttling bolt 6 is used to block airflow and create airflow disturbance. It is preferably placed between the two connecting holes 42, and its screw-in length is determined according to the physical and chemical properties of the transported material.
