Description

Technical Field

[0001] The invention relates to the technical field of reaction furnaces, in particular to an energy-saving rotary reaction furnace for chemical industry. Background Art

[0002] Energy-saving chemical rotary reactors usually adopt some advanced designs and technologies to reduce energy consumption and improve efficiency.

[0003] The patent with patent announcement number CN108972865B relates to an operating method for rotary microwave sintering of expanded clay with fly ash from garbage incineration. In this method, the fly ash from garbage incineration is mixed with pyrite slag and granulated. After granulation, the expanded clay is put into a rotary furnace body together with microwave coupling agent powder for microwave sintering. By tilting the rotary reactor, the expanded clay is heated by microwaves while rolling and mixing. After sintering, the expanded clay clinker is separated from the microwave coupling agent, and the separated microwave coupling agent is returned as a raw material for reuse. This innovation improves the utilization rate of the microwave coupling agent. At the same time, the preparation process of this patent is simple, and energy utilization is sufficient. It solves the problem of generating a large amount of harmful flue gas that needs to be purified in traditional sintering technology, promotes the industrialization process of microwave sintering of incineration fly ash, and is particularly suitable for fly ash harmless treatment for the purpose of sintering expanded clay with incineration fly ash.

[0004] In the above patent, the expanded clay clinker is separated from the microwave coupling agent after sintering, and the separated microwave coupling agent is returned as a raw material for reuse. This innovation improves the utilization rate of the microwave coupling agent. However, the material needs to be pretreated before reacting. If the material is too large, it will lead to insufficient combustion, which will reduce production efficiency and fail to meet the expected requirements. Summary of the invention

This improves the stability and reliability of the device. The telescopic clamping plate is driven to contract by a round rod so that when the telescopic clamping plate moves in the opposite direction, the movable end of the telescopic clamping plate will not contact the bottom of the feed box, preventing the telescopic clamping plate from scraping the material away from the feed port when moving toward both ends, resulting in the material being unable to enter the rotary kiln. This improves the applicability and stability of the device.

[0017] (2) The invention drives the scraper to rotate through the transmission block, and the scraper rotates to scrape away the slag on the inner wall of the rotary kiln, so as to prevent the excessive slag on the inner wall of the rotary kiln from causing the heat to be insufficiently transferred to the material, resulting in insufficient combustion of the material, and causing the material to fail to meet the production standards and cause waste, thereby reducing production costs and improving production efficiency. The scraper plate is driven by the circular ring to move, and the movement of the scraper plate will scrape out the material remaining in the corner of the feed port, preventing the waste caused by the accumulation of materials, and improving the applicability and protection effect of the device.

[0018] (3) The invention drives the transmission arc rod to rotate through the transmission column, and the transmission arc rod rotates to push the coolant into the rotary kiln, so that a quantitative amount of coolant is added to the inside of the rotary kiln after each rotation, without the need for manual addition, saving expenses and reducing production costs. The concave groove is blocked by a locking block, so that the cover plate cannot be opened when the rotary kiln is working, preventing workers from adding coolant to the storage box when the rotary kiln is working, thereby improving the safety of workers at work and the protection effect on workers.
