Description

Water bath heating device for synthesizing quinclorac Technical Field The utility model relates to the technical field of quinclorac synthesis devices, in particular to a water bath heating device for quinclorac synthesis. Background The quinclorac is a product for weeding developed by Beijing Fagai silver science and technology Co-Ltd, and the pure product is light yellow powder with uniform appearance and no pungent peculiar smell. The weeding composition has good weeding effect on barnyard grass, crab grass, polygonum caryophyllum, snakehead intestines and other weeds, is outstanding in weeding against barnyard grass of penoxsulam, can effectively weed broadleaf weeds in paddy fields such as duck tongue grass, ear She Shuixian and the like, has quick weeding effect, can cause yellowing symptoms of internal tissues in 3-5 days after the weeds are absorbed, and can cause dead spots along with the yellowing symptoms, and the weeding composition gradually whitens and dies throughout the whole plant after 1-2 weeks. In the existing synthesis process of quinclorac, specifically, in the step of acylation reaction, water bath heating is needed to dissolve the acylating agent, the acylating agent is firstly added into an organic solvent, then water bath is heated to 70-80 ℃ to dissolve the acylating agent completely, and the acylating agent is kept at a temperature. However, the existing laboratory water bath heating device is used for rapid heating, the bottom of a container is usually placed on an internal support of water bath equipment, the reaction condition of the lower side of the water bath heating container cannot be intuitively observed, and the risk of scalding is easily caused by direct taking and observing for many times due to the higher temperature of the water bath equipment. Disclosure of utility model The utility model aims to provide a water bath heating device for synthesizing quinclorac, which aims to solve the defects in the prior art. In order to achieve the above object, the present utility model provides the following technical solutions: The water bath heating device for synthesizing quinclorac comprises a heating box body, a cover body and a lifting assembly, wherein an electric heater is arranged in the heating box body, the cover body is placed on the heating box body, the lifting assembly is arranged on the cover body and comprises a supporting frame, the supporting frame is in threaded connection with a screw hole on a rotary table, the rotary table is rotationally connected to the cover body, the rotary table is connected with a driving piece, and a limiting rod for limiting the rotation of the supporting frame is further arranged on the cover body. Further, the support frame comprises a bottom plate, a screw is fixedly connected to one side of the bottom plate, the screw is in threaded connection with the screw hole, a limit groove is formed in one side of the bottom plate, and the limit groove is in sliding connection with the limit rod. Further, the driving piece comprises a worm wheel fixedly arranged on the outer side of the rotary table, the worm wheel and the rotary table are concentrically arranged, a worm is connected to the worm wheel in a meshed mode, and the worm is arranged on the cover body in a rotating mode. Further, the lifting assembly is provided with a plurality of worms, each worm is fixedly connected to the control rod, the control rod and the worm are concentrically arranged, and the control rod is rotatably connected to the cover body.
