Description

Technical Field

[0001] The utility model belongs to the technical field, and particularly relates to waste residue treatment equipment for the production of pharmaceutical intermediates. Background Art

[0002] As the name suggests, pharmaceutical intermediates are some chemical raw materials or chemical products used in the process of drug synthesis. They do not require a drug production license and can be produced in ordinary chemical plants. As long as they reach a certain level, they can be used in the synthesis of drugs. Solid waste will be generated in some reactions, such as filter residues and crystalline products. These solid wastes need to be treated to ensure their safe discharge or resource utilization.

[0003] The production process of some pharmaceutical intermediates will produce waste containing toxic, harmful or flammable substances, which need to be safely handled to prevent harm to the environment and human health. Incineration is an effective high-temperature treatment method that can completely destroy these hazardous wastes and reduce their impact on the environment. However, in existing pharmaceutical intermediate incineration devices, the accumulation of waste residues often makes it difficult for some of the waste to be completely burned, resulting in an uneven combustion process and increasing the difficulty of subsequent treatment.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a stirring mechanism, when the waste slag in the waste slag incineration box starts to burn, the motor can be started, and the motor drives the rotating shaft three to rotate through the pulley and the belt, and the rotating shaft three drives the large gear to rotate slowly through the small gear, thereby driving the rotating shaft one to rotate, and the rotating shaft one drives the stirring block on the connecting rod to rotate, and stirs the waste slag being burned in the waste slag incineration box, so that it is evenly distributed in the incineration box, which is conducive to full exposure to the high temperature environment, helps to promote the uniform combustion of waste, reduce residues, and improve the incineration efficiency, helps the waste to better contact with fuel and oxygen, and promotes the combustion reaction, thereby improving the heat transfer efficiency, so that the waste reaches the combustion temperature faster, and reduces the situation of unburned or partially burned, and can also reduce the accumulation and accumulation of waste during the incineration process, reduce the existence of cold areas in the incinerator, thereby reducing the generation of harmful substances in exhaust gas emissions, and improving the environmental friendliness of the incineration process;
