DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Please refer to Figure 1-8 ;

[0028] The freeze-drying evaporation chamber device of the utility model configures the chamber body 1 into a double-layer structure so that the chamber body 1 can withstand greater pressure and prevent deformation caused by long-term use. A "concave"-shaped annular buffer pad 5 is coated on the bottom of the chamber body 1. The annular buffer pad 5 plays a role of buffering protection, thereby minimizing impact damage and increasing the service life of the chamber body 1.

[0029] A freeze-drying evaporation chamber device comprises a chamber 1. The shape of the chamber 1 can be a rectangular parallelepiped, a cylinder or the like. The cylindrical shape is preferably adopted in this embodiment. The chamber 1 is a double-layer structure, which can withstand a large pressure to prevent the chamber 1 from being deformed during long-term use. The bottom of the chamber 1 is covered with an annular buffer pad 5, which plays a role of buffering protection and minimizes impact damage. The outer periphery of the chamber 1 is provided with a copper tube 6 arranged in a spiral shape. The copper tube 6 is in outer circular line contact with the side wall of the chamber 1, so as to transfer the temperature to the chamber 1. The copper tube 6 is connected to an external control system to form a copper tube evaporator. The copper tube 6 is controlled by the external The control system realizes the refrigeration function of the freeze-drying chamber. The refrigeration of the cabin 1 requires a low temperature of minus 45 degrees. A number of support members 7 are arranged under the copper tube 6. The lower end face of the support member 7 is threadedly connected with an annular fixing plate 61. One side of the annular fixing plate 61 is abutted against the outer wall of the cabin 1. The annular fixing plate 61 is used to place foam parts. The foam parts are used to provide thermal insulation and flame retardant functions for the cabin 1. An exhaust pipe 8 and a drain pipe 9 are respectively provided on the side of the cabin 1 away from the support member 7. The exhaust pipe 8 is connected to an external vacuum pump, and the gas is pumped out of the cabin through the vacuum pump. The drain pipe 9 is used to pump out the water in the cabin. The drain pipe 9 of the utility model needs to be manually operated to open and close the drain valve.

[0030] Specifically, a foaming part is first placed outside the cabin 1, and then the items to be processed are placed in the cabin after being frozen at low temperature; the vacuum pump starts to draw a vacuum, and the external control system transmits cold air to the cabin 1 through the copper tube 6, so that the cabin 1 starts to refrigerate. When the vacuum degree reaches a certain value, the ice condensed in the items sublimates into water vapor, and the water vapor contacts the inner wall of the cabin 1 with a lower temperature and is condensed into ice and attached to the inner wall of the cabin 1. After the moisture of the items is fully extracted, the vacuum pump and the refrigeration system stop working, and the ice condensed on the wall of the cabin 1 is melted into water by heating or absorbing natural heat and gathers at the bottom of the cabin 1, and finally the water is discharged through the drain pipe 9.

[0031] In addition, a heater can be installed in the cabin 1, and the items to be processed are placed on the heater. The heat is transferred to the items to be processed through radiation from the heater. After the items to be processed absorb heat, the moisture in them gradually sublimates, thereby accelerating the drying of the items to be processed.

[0032] In this embodiment, a fixing seat 3 is provided at the lower end of the cabin body 1, and a through hole 31 is provided on the fixing seat 3. A plurality of L-shaped brackets 32 are distributed in a circular array at the lower end of the fixing seat 3. The cabin body 1 passes through the through hole 31, and the annular buffer pad 5 at its lower end abuts against the L-shaped bracket. The utility model is provided with three L-shaped brackets 32 for abutting the annular buffer pad 5.

[0033] Furthermore, a shell 2 for placing the cabin 1 is provided on the fixing seat 3. The shape of the shell 2 is consistent with that of the cabin 1, and both are cylindrical. A plurality of positioning blocks 33 are provided on the fixing seat 3. A plurality of positioning grooves 21 for clamping the plurality of positioning blocks 33 are provided at the bottom of the shell 2. The positioning blocks 33 are used for installation and positioning of the shell 2. During installation, the installation of the shell 2 can be completed by aligning the positioning grooves 21 of the outer shell body with the positioning blocks 33 and inserting them, thereby improving the installation efficiency of the shell 2 and the accuracy of the installation position. A foaming space is provided between the shell 2 and the cabin 1, and the foaming space is used for the injection of slurry. The slurry is injected and covers the outer surface of the cabin 1 to form a foamed part. One side of the annular fixing plate 61 abuts against the outer wall of the cabin 1, and the other side of the annular fixing plate 61 abuts against the inner wall of the shell 2 to form a sealing structure. The annular fixing plate 61 abuts against the outer wall of the cabin 1 and the inner wall of the shell 2 respectively to form a sealing structure, so as to prevent the slurry from flowing out from the gap of the annular fixing plate 61 when the slurry is injected into the foaming space, resulting in waste of the slurry.

[0034] In this embodiment, a plurality of through holes 22 are provided on the side wall of the housing 2 for the exhaust pipe 8 , the drain pipe 9 and the copper pipe 6 to extend out.

A positioning groove 23 for clamping the plurality of positioning blocks 41 is provided on the shell 2. The positioning groove 23 is used for positioning the end cover 4 during installation. During installation, the positioning block 41 of the end cover 4 only needs to be aligned and inserted into the positioning groove 23 to complete the installation of the end cover 4, thereby improving the installation efficiency of the end cover 4.

[0036] Furthermore, the end cover 4 is provided with a plurality of clamping holes 43 for installing the counterweight 42, and the bottom of the counterweight 42 is provided with a plurality of clamping blocks 44 that are clamped with the clamping holes 43. The counterweight 42 is used to increase the weight of the end cover 4. The utility model adopts three parallel counterweights 42, one of which is installed in the middle of the end cover 4, and the other two counterweights 42 are symmetrically installed on both sides of the upper end surface of the end cover 4, so that the end cover 4 is evenly weighted to prevent the end cover 4 from being lifted up when the slurry is molded, resulting in product molding failure.

The utility model adopts 8 locking components 24, and the shell 2 is locked and matched by the locking components 24. The shell 2 includes a shell 1 25 and a shell 2 26. The outer shell 25 fits tightly with the shell 2 26 to ensure that the shell 2 is completely closed during the injection and foaming of the material liquid to prevent the foaming material liquid from leaking out. A fixing piece 241 is provided on the shell 1 25, and the fixing piece 241 is provided with a convex semicircular surface on the outer edge facing the fixing block 261. The locking component 24 includes a handle 242 rotatably connected to the fixing piece 241, and a groove 243 for inserting the fixing piece 241 is provided on the handle 242.
