This utility model discloses a mixing device for raw materials in the production of methyl cedarwood ether, including a mixing tank, a discharge port installed at the bottom of the mixing tank, and a support frame installed outside the mixing tank. It also includes a mounting plate fixedly connected to the outside of the mixing tank, a storage tank for storing raw materials installed on top of the mounting plate, a conveying assembly installed on the mixing tank, and a mixing assembly installed inside the mixing tank. The conveying assembly transports the raw materials from the storage tank into the mixing tank, and the mixing assembly mixes the incoming raw materials. By storing materials in multiple storage tanks for different categories, and coordinating with a conveying pump to synchronously transport raw materials according to a preset ratio with a conveying accuracy of ±1%, the proportions strictly meet production requirements. Simultaneously, the first spiral blade inside the conveying cylinder achieves synchronous pre-mixing, avoiding the problem of intervals in multiple feedings. Local concentration fluctuations of the raw materials are controlled within 5%, significantly reducing the occurrence of side reactions, and increasing the purity of the methyl cedarwood ether product to over 98%.

This invention relates to the field of solid waste treatment technology, and in particular to a method for multi-stage countercurrent water washing and dechlorination of waste incineration fly ash with a low liquid-to-solid ratio. This invention combines low liquid-to-solid ratio water washing with countercurrent water washing, and utilizes a rotary vibrator to achieve effective dechlorination of waste incineration fly ash, ultimately obtaining water-washed fly ash with a chlorine content of less than 1%. Compared with existing technologies, this invention organically combines low liquid-to-solid ratio water washing, countercurrent water washing, and a rotary vibrator, balancing dechlorination efficiency and water resource utilization. The process is stable and reliable, simple to operate, and has low energy consumption. The treated fly ash meets the requirements for subsequent resource utilization, providing an efficient and feasible new solution for the harmless treatment and resource recovery of waste incineration fly ash.
