Description

Technical Field

[0001] The invention relates to the field of experimental devices, and in particular to an automatic disassembly and assembly system and method for reaction tubes of an experimental multi-channel device, and an experimental multi-channel device. Background Art

[0002] Fixed bed reactors are widely used in catalyst evaluation in the fields of chemical industry, petroleum and new materials. They have become an important carrier for research and production due to their simple structure, easy scale-up and stable operation. With the development of high-throughput screening technology, the demand for rapid experiments with multiple components and multiple conditions is increasing. However, most existing fixed bed evaluation devices can only achieve online monitoring and partial automatic control, and cannot achieve full automation in the disassembly and assembly of reaction tubes, catalyst loading and pipeline connection.

[0003] Although the existing multi-channel parallel reaction system can test multiple catalyst samples in parallel, it often requires space for manual operation between the reaction tubes, so the system occupies a large area. In addition, each time the catalyst is replaced, the pipeline must be manually disassembled and assembled, which is time-consuming, labor-intensive and inefficient. Although some high-throughput screening devices have achieved a high degree of automation in data acquisition and process control, manual operation is still required to disassemble and load the reaction tubes, making it impossible to form an unmanned operation of the entire process from experimental preparation to the end of the test. Especially under harsh conditions such as high temperature and high pressure, the reliability requirements for automatic docking, sealing and disassembly and assembly are higher, further increasing the technical difficulty of full automation.

[0004] At present, there are no mature reports or commercial equipment that can achieve fully automatic disassembly and assembly and rapid catalyst replacement for fixed-bed reactor tubes, which makes it difficult to meet the higher requirements of efficiency and safety for high-throughput screening. How to integrate automated movement, precise positioning and sealed disassembly and assembly technology in multi-channel devices, reduce manual intervention and shorten the spacing between devices has become an urgent problem to be solved in the field of catalyst screening and development. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an automatic disassembly and assembly system for reaction tubes of a multi-channel device for experiments. The automatic disassembly and assembly system realizes automatic disassembly and assembly of reaction tubes through the combined action of a cylinder and an internal expansion clamp.

When the pneumatic connector is placed on the pneumatic connector fixing part, the internal expansion clamp can be inserted into the quartz tube to be removed.

[0015] Wherein, the automatic disassembly and assembly system also includes a pipeline bridge for placing pipelines;

[0016] And / or, the automatic disassembly and assembly system also includes a quartz tube bracket.

[0017] A multi-channel device for experiments comprises a reaction furnace and the above-mentioned automatic disassembly and assembly system for reaction tubes of the multi-channel device for experiments, wherein the quartz tube to be taken out is located in the reaction furnace.

[0018] An automatic disassembly and assembly method for a reaction tube of an experimental multi-channel device comprises the following steps:
