However, when the distillation device is used to distill sticky or easily aggregated materials, the materials are prone to accumulate or agglomerate inside the device.

When the device is performing distillation, the accumulation or agglomeration of the material will cause local temperature and concentration changes inside the equipment, thus affecting the progress of the reaction and the purity of the product.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a distillation device for producing pharmaceutical intermediates, comprising a rectangular bottom plate, on which a vibration mechanism and an adaption mechanism are arranged;
[0007] The vibration mechanism includes a distillation cylinder arranged at the central axis above a rectangular bottom plate, two rectangular support plates are fixedly connected to the top of the rectangular bottom plate, the two rectangular support plates are arranged on the front and rear sides of the rectangular bottom plate, two rotating shafts 1 are rotatably connected between the two rectangular support plates, the two rotating shafts 1 are arranged on the left and right sides of the two rectangular support plates, two adapting U-shaped plates are fixedly connected to the bottom outer wall of the distillation cylinder, collision sleeves are respectively fixedly connected to the two rotating shafts 1, and the two collision sleeves are respectively adapted to the two adapting U-shaped plates.
[0008] Furthermore, a second rotating shaft is rotatably penetrated through the rectangular support plate located at the front side, and a front side extension portion of the second rotating shaft is fixedly connected to a motor.
[0009] Furthermore, a small gear is fixedly connected to the rear extension of the rotating shaft 2, and large gears are fixedly connected to the front outer walls of the two rotating shafts 1 respectively, and the left and right sides of the small gear are respectively meshed with the two large gears.
[0010] Furthermore, the adapting mechanism comprises a plurality of arc-shaped support plates fixedly connected to the top of the rectangular bottom plate, and a connecting block 1 is fixedly connected to one side of the plurality of arc-shaped support plates away from the rectangular bottom plate.
[0011] Furthermore, a sleeve is hingedly provided on one end of a plurality of the connection blocks away from the arc-shaped support plate, and a slider is slidably connected to the inner wall of a plurality of the sleeves.
[0012] Further, one end of several sliders away from the arc-shaped support plate is fixedly connected to a connecting rod, one end of several connecting rods away from the sliders is respectively slidably extended to the outside of several sleeves, the outer walls of several connecting rods are respectively sleeved with springs 1, one side of several springs 1 away from the distillation cylinder is respectively fixedly connected to the slider, and one side of several springs 1 away from the arc-shaped support plate is respectively fixedly connected to the sleeve;
[0013] Furthermore, a plurality of connection blocks 2 are fixedly connected to the outer wall of the distillation cylinder, and the ends of the plurality of connection blocks 2 away from the distillation cylinder are respectively hinged to a plurality of connection rods, and a sliding rod is fixedly connected to the central axis of the bottom of the distillation cylinder, and the end of the sliding rod away from the distillation cylinder slides and extends through the rectangular bottom plate and to the outside;

[0015] The utility model has the following beneficial effects:
[0016] 1. By setting a vibration mechanism, the motor on the rectangular support plate is started during distillation, and the motor drives the second rotating shaft to rotate, thereby driving the small gear to rotate. The small gear drives the two rotating shafts to rotate slowly through the large gear, thereby driving the two collision sleeves to collide with the matching U-shaped plate on the distillation cylinder, thereby generating vibration, so that the material can be evenly distributed and flowed inside the equipment, preventing material accumulation and agglomeration, helping to maintain the continuity and stability of the production process, avoiding production interruptions and quality problems caused by agglomeration, and promoting mixing and flow between materials, thereby improving mass transfer efficiency and reaction rate, thereby ensuring the uniformity and efficiency of the reaction, and improving the yield and quality of the product;

When the distillation cylinder vibrates, the distillation cylinder will pull the slide bar on the connecting rod under the connection of the connecting block 2 to compress the spring 1 in the sleeve, thereby reducing the fatigue of the spring 2, further enhancing the vibration effect of the device, so that the vibration generated by the vibration mechanism can be effectively reduced and transmitted to other parts or structures of the equipment, which helps to reduce the vibration level of the equipment, reduce the mechanical wear and noise of the equipment, and extend the service life of the equipment. The vibration mechanism will generate certain vibration forces when working. When these vibration forces are directly transmitted to the structure of the equipment, they will affect the stability and safety of the equipment. At this time, the adapted shock-absorbing mechanism can effectively slow down the transmission of these vibration forces and protect the structure of the equipment from damage.
