Description

Technical Field

[0001] The utility model relates to the technical field of freeze dryers, in particular to a high-pressure air-cooled freeze dryer. Background Art

[0002] A high-pressure air-cooled freeze dryer is a machine that cools compressed air by forced heat exchange through an evaporator according to the principle of freeze dehumidification, so that gaseous water and oil in the compressed air are cooled isobarically and condensed into liquid water and oil, which are discharged outside the machine through an automatic drainer, thereby obtaining dry and clean compressed air. Most of the current high-pressure air-cooled freeze dryers are of an integrated design, and the compressor equipment is installed inside the machine body. During the operation of the dryer, a certain degree of vibration will occur. After long-term operation, the machine body is prone to positional deviation, resulting in a change in the working position, which is not conducive to the operation of the dryer; and sometimes the dryer also needs to move the working position according to different operations. When the dryer needs to be moved during use, the heavy weight of the machine body makes the moving operation difficult. Summary of the Utility Model

An auxiliary traction mechanism 2 is provided on the bottom surface of the dryer structure 1, and a cooling fan 3 is installed on the left surface of the dryer structure 1;

[0030] As Figure 2 shown, the dryer structure 1 specifically includes a body 11, an end cover 12 fixedly connected to the top surface of the body 11, and a bottom plate 19 fixedly connected to the bottom surface of the body 11. An air inlet 14 and an air outlet 13 are respectively provided on the front side and the rear side of the top surface of the end cover 12. Support feet 16 are fixedly provided at the front and rear of the bottom surface of the bottom plate 19; Rubber blocks 18 are fixedly connected to the bottom ends of the telescopic shafts of the servo electric cylinders 17 on both the left and right sides of the bottom surface of the support feet 16.

[0031] Specifically, a control panel 15 is installed in the top area of the front surface of the body 11, and a heat dissipation port 110 is provided in the bottom area of the left surface of the body 11; The support feet 16 are symmetrically arranged in a front-back mirror image with the midline of the bottom plate 19 as the base point, and through holes for lightweighting are provided inside the support feet 16. The servo electric cylinders 17 are symmetrically arranged in a left-right mirror image with the central axis of the support feet 16 as the base point. The housing of the cooling fan 3 is locked to the left end face of the heat dissipation port 110 by screws.

[0032] As Figure 3 shown, the auxiliary traction mechanism 2 specifically includes a square frame 21, a coded motor drive board 23 fixed in the inner cavity of the square frame 21, and four coded motors 22 fixedly connected to the four corner areas of the inner cavity of the square frame 21.
