Embodiment Construction
[0014] The content of the present invention will be described below in conjunction with specific embodiments.
[0015] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a rotary evaporator proposed by the present invention.
[0016] refer to figure 1 , a kind of rotary evaporator that the present invention proposes, comprises: base 1, water-bath crucible 9, evaporating bottle 4, condensation tube 6, vacuum pump 17, cooling box 15, collecting bottle 7;
[0017] The base 1 is provided with a support 2, the evaporating bottle 4 and the condenser tube 6 are connected to the support 2, the evaporating bottle 4 is arranged obliquely, and the evaporating bottle 4 is driven by a motor 3 to rotate around its axis, The water bath crucible 9 is located below the evaporating flask 4; the condensation pipe 6 communicates with the evaporating flask 4, and the condensation pipe 6 is connected with a water injection pipe 5, and the outlet of the water injection pi...

The invention relates to a rotary evaporator. An evaporation bottle is obliquely arranged, a driving motor drives the evaporation bottle to rotate around the axis of the evaporation bottle, a water bath crucible is positioned below the evaporation bottle, a condenser pipe is communicated with the evaporation bottle, a water filling pipe is connected on the condenser pipe, an output of the water filling pipe extends into the evaporation bottle from the condenser pipe, an air discharging port is formed in the condenser pipe and communicated with a vacuum pump through a pipeline, a liquid discharging port is formed in the bottom of the condenser pipe and communicated with a collection bottle, a heat exchange coil pipe is arranged in the condenser pipe and provided with a water inlet and a water outlet, the water inlet and the water outlet are communicated with a cooling box through pipelines, a peristaltic pump is arranged on the pipeline between the water inlet of the heat exchange coilpipe and the cooling box, cooling liquid is arranged in the cooling box and connected with a screen bag, and the screen bag is filled with stainless steel ice blocks. According to the rotary evaporator, the cooling efficiency of water vapor is greatly improved, evaporation efficiency is improved, and volatile matters cannot be sucked into a vacuum pump.
Description
technical field [0001] The invention relates to the field of evaporators, in particular to a rotary evaporator. Background technique [0002] Pharmaceutical factories and chemical factories usually use reactors to produce new products. Due to the complex structure and bulkiness of reactors, it is not convenient to use them when producing a small amount of products. When a small amount of products needs to be produced, a rotary evaporator is used at the same time. The traditional rotary evaporator has low evaporation efficiency, slow condensation of volatiles and long distillation time. The above problems need to be solved urgently. Contents of the invention [0003] The present invention just aims at the deficiencies in the prior art and provides a rotary evaporator. [0004] In order to solve the above problems, the technical scheme adopted in the present invention is as follows: [0005] A rotary evaporator, comprising: a base, a water bath crucible, an evaporating fl...
