Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, specifically a rotary distillation collection device. Background Technology

[0002] A rotary evaporator, also known as a rotary distillation apparatus, is a widely used evaporation instrument in laboratories. It consists of a motor, distillation flask, heating pan, condenser, and other components. It is mainly used for the continuous distillation of volatile solvents under reduced pressure and is applied in fields such as chemistry, chemical engineering, and biomedicine.

[0003] For example, announcement number CN220572680U, entitled "A Rotary Evaporator," includes a control cabinet, a water bath, a rotary distillation flask, a drive mechanism, a support rod, a condenser, a collection bottle, a gas delivery bottle, and a vacuum system. The water bath is installed on the front of the control cabinet. The rotary distillation flask is rotatably mounted on the upper end of the control cabinet and connected to the drive mechanism. The support rod is installed on the rear of the control cabinet. The condenser and the collection bottle are interconnected on the support rod. The condenser and the rotary distillation flask are connected through the gas delivery bottle. The vacuum system is connected to the condenser. The device also includes an extension frame, an opening and closing cylinder, and a protective cover. The extension frame is fixedly connected to the control cabinet. An opening and closing cylinder electrically connected to the control cabinet is installed on its upper end. The extension end of the opening and closing cylinder is connected to the protective cover. The protective cover is fastened to the upper port of the water bath. A clearance opening is provided on the rear side of the protective cover.

[0004] However, the existing cylinder is only connected to the extension plate through the telescopic end, and the protective cover has no lateral restraint. It is easy to wobble during lifting and lowering, which affects the stability of lifting and lowering. In addition, when the negative pressure is used for air extraction, water vapor is easily extracted along with it, which affects the water volume of the water bath. Therefore, it does not meet the existing requirements. To address this, a rotary distillation collection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rotary distillation collection device to solve the problems mentioned in the background art, such as the existing cylinder being connected to the extension plate only through the telescopic end, the protective cover having no lateral restraint, being prone to swaying during lifting and lowering, affecting the stability of lifting and lowering, and being prone to extracting water vapor along with the air during negative pressure extraction, affecting the water volume of the water bath.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary distillation collection device, comprising: a water bath, inside which a rotary evaporator is disposed, and a lifting and displacement component is installed at the rear of the water bath, the lifting and displacement component including a bracket, two sets of slide rails symmetrically mounted on the outer wall of the front end face of the bracket, displacement sliders mounted on the outer walls of the two sets of slide rails, L-shaped assembly frames mounted on the outer walls of the two sets of displacement sliders, connecting columns mounted at the bottom of the two sets of assembly frames, a cover provided at the lower end of the connecting column, a connecting frame between the two sets of displacement sliders, and a driving cylinder mounted above the connecting frame.

[0007] Preferably, a top plate is integrally provided on the upper top of the bracket, and the drive cylinder is bolted to the upper surface of the top plate. The drive cylinder includes a pneumatic telescopic rod, and the lower end of the pneumatic telescopic rod is connected to the upper surface of the connecting frame.

[0008] Preferably, a negative pressure suction pipe is installed on the upper surface of the top plate, and a telescopic pipe is installed at the lower end of the negative pressure suction pipe. The bottom of the telescopic pipe is connected to the cover body through a flange.

[0009] Preferably, a demister is installed inside the cover, and the demister is composed of several blades forming a honeycomb-like structure.

[0010] Preferably, the lower surface of the cover is provided with an annular cover opening barrier, and the lower surface of the cover opening barrier is provided with a plurality of annularly spaced inserts. The upper surface of the water bath is provided with a pot opening barrier, and the upper surface of the pot opening barrier is provided with a plurality of annularly spaced inserts.

[0011] Preferably, an arc-shaped rubber sealing block is provided on the outer wall of the lid enclosure and the pot opening enclosure, and an opening is provided on the outer wall of the arc-shaped rubber sealing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In this utility model, the cover is connected to two sets of L-shaped assembly frames by two sets of symmetrical connecting columns. The L-shaped assembly frames are fixed to two sets of displacement sliders by bolts. The two sets of displacement sliders slide up and down on two sets of slide rails. The slide rails restrict the displacement sliders. The two sets of displacement sliders are connected and combined together by the connecting frame. A drive cylinder is installed at the top. The extension end of the drive cylinder is connected to the connecting frame. The drive cylinder drives the two sets of displacement sliders to move at one time, so that the cover can rise and fall smoothly during the lifting and lowering process, which improves the stability.

[0014] (2) In this utility model, by setting up a demister, the liquid droplets in the gas flow in a tortuous manner and collide with the wall surface, gradually agglomerating into large droplets and then sliding down the blades, thereby achieving the effect of separating the liquid in the gas.

[0015] (3) In this utility model, the cover opening guard at the bottom of the cover body is used to combine with the pot opening guard so that the two arc-shaped rubber sealing blocks are combined together to improve the sealing performance at that point. The opening is for the neck of the rotary evaporator to pass through. When combined, the cover body moves downward and the plug of the cover opening guard is inserted into the corresponding insertion hole. When separated, the cover body moves upward and the plug of the cover opening guard moves upward and disengages from the insertion hole. The above structure can adapt to the lifting and lowering displacement of the cover body, making it convenient to combine and separate during the lifting and lowering displacement.
