[0002] Guanidine thiocyanate is widely used as a biochemical reagent for denaturing and lysing cells and extracting RNA and DNA. The finished product is typically produced through a series of steps: synthesis, desalting, crystallization, drying, and packaging.

[0003] Regarding equipment support for the drying stage, the invention with authorization announcement number CN101988788B discloses a single-cone dryer with a single-screw agitator. The dryer comprises a conical housing and agitator, a top cover, a rod-type collector, a vacuum pump, and an air source. The agitator is a single-screw agitator vertically arranged within the conical housing. The agitator comprises a stirring spindle, stirring blades, and a support member, with the stirring blades secured to the stirring spindle via the support member.

A filter cover is provided at one end of each of the vacuum tube and the gas backflush tube, and the filter cover is enclosed by a filter medium. An automatic diaphragm valve is provided between the gas backflush tube and the air source. This single-cone dryer can shorten drying time, ensure uniform product quality and eliminate lumps, and improve drying efficiency and drying results.

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, a brief introduction will be given below to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] See also Figure 1 and Figure 2 The embodiment of the utility model provides a high-efficiency drying device for guanidine thiocyanate, including a shell 10 and a flipping component 20. The shell 10 is provided with a cavity. The flipping component 20 includes a main shaft 21, a support rod 22, and a unit spiral ribbon 23. The main shaft 21 is built into the cavity and rotates relative to the cavity. The support rod 22 is provided on the main shaft 21. There are several support rods 22, and the several support rods 22 are spirally arranged along the axial direction of the main shaft 21. There are several unit spiral ribbons 23, and the several unit spiral ribbons 23 are connected end to end to form a spiral shape around the main shaft 21. The support rods 22 and the unit spiral ribbons 23 are connected by welding points 24, and the unit spiral ribbons 23 are connected by welding points 24.

[0024] Exemplarily, each unit spiral belt 23 is connected to a support rod 22 , or both ends of a unit spiral belt 23 are respectively connected to two adjacent support rods 22 .

[0025] Beneficial effect: Compared with the prior art which adopts an integral spiral stirring blade, the present application uses several unit spiral ribbons 23 connected end to end to form an integral spiral ribbon. The unit spiral ribbon 23 is short and the installation position with the support rod 22 is easy to control. The support rod 22 and the unit spiral ribbon 23 are connected by welding points 24, which is easy to install and has high installation efficiency. After the unit spiral ribbon 23 and the support rod 22 are welded, the unit spiral ribbons 23 are connected by welding points 24, which is convenient for adjusting the connection position between the unit spiral ribbons 23. The shape of the integral spiral ribbon is easy to adjust, and the distance between the unit spiral ribbon 23 and the inner wall of the cavity is easy to control, and the installation accuracy is high.

[0026] Exemplarily, the number of the unit spiral belts 23 corresponds to the number of the support rods 22 .

[0027] For example, it is preferred that four support rods 22 are provided within one pitch.

[0028] In one embodiment, the unit spiral belt 23 does not contact the main shaft 21, and a gap is formed between the main shaft 21, the support rod 22, and the unit spiral belt 23. While the material in the cavity is pushed upward by the unit spiral belt 23, it flows down from the gap without hindrance, promoting sufficient internal circulation of the material in the cavity and enhancing the drying effect.

[0029] For example, the strength of the support rod 22 is lower than that of the unit spiral ribbon 23. For example, a break groove is provided at the end of the support rod 22, and the break groove is coaxial with the main shaft 21. The depth of the break groove can be determined based on empirical data. Based on the design in which the strength of the break groove or the support rod 22 is lower than that of the unit spiral ribbon 23, when the resistance to the unit spiral ribbon 23 exceeds a safe limit, the support rod 22 breaks first, thereby protecting the unit spiral ribbon 23.

[0030] In one embodiment, two adjacent unit screw bands 23 are connected by a bump. The unit screw bands 23 and the bump are connected by a weld 24. The bump acts as a baffle, facilitating upward movement of the material. The bump and the unit screw bands 23 are connected by bolts, for example, which are difficult to install and difficult to remove after wearing the bolts.

[0031] See also Figure 1 and Figure 2 Furthermore, the turning component 20 is used to transport the material from the lower part of the cavity to the upper part of the cavity.

[0032] See also Figure 1 and Figure 2 Furthermore, the length of the support rod 22 gradually decreases from the upper end of the main shaft 21 to the lower end of the main shaft 21.

[0033] See also Figure 1 and Figure 2 Furthermore, the radius of the unit spiral ribbon 23 gradually decreases from the upper end of the main shaft 21 to the lower end of the main shaft 21.

[0034] See also Figure 1 and Figure 2 Furthermore, several unit screws surround the main shaft 21 to form a shape that matches the cavity.

[0035] See also Figure 1 and Figure 2 , further, the main shaft 21 is coaxially arranged with the cavity.

[0036] See also Figure 1 and Figure 2 , further, the housing 10 is conical.

[0037] See also Figure 1 and Figure 2 , further, the cavity is conical.

[0038] See also Figure 1 and Figure 2 Furthermore, the guanidine thiocyanate efficient drying device further includes a cover 30 . The shell 10 has upper and lower openings, and the cover 30 is disposed on the upper end surface of the shell 10 .

[0039] Exemplarily, the shell 10 and the cavity are both larger at the top and smaller at the bottom.

[0040] See also Figure 1and Figure 2 Furthermore, the guanidine thiocyanate efficient drying device also includes a discharge valve 40. The lower end surface of the shell 10 is a discharge port, and the discharge valve 40 is installed on the discharge port.

[0041] For example, a loading port is provided on the cover 30, and the cavity can be exhausted by vacuum.

[0042] Exemplarily, the main shaft 21 is driven by a motor 50 , which is fixed relative to the shell 10 . The motor 50 can be installed on the cover 30 . The main shaft 21 passes through the cover 30 and is rotationally connected to the cover 30 . The main shaft 21 is driven by the motor 50 to rotate relative to the shell 10 .

[0043] See also Figure 3 and Figure 4 In one embodiment, the guanidine thiocyanate high-efficiency drying device further includes a coil assembly 60, which is embedded in the annular wall of the shell 10. The coil assembly 60 is used to heat the cavity. The coil assembly 60 includes an upper coil 61 and a lower coil 62. The lower end of the lower coil 62 is a heating medium inlet, the upper end of the lower coil 62 is connected to the lower end of the upper coil 61, and the upper end of the upper coil 61 is a heat medium outlet. The lower coil 62 is spirally shaped on the shell 10 so that the heating medium preferably forms a horizontal flow state in the lower coil 62, and the heat transfer effect is poor. The upper coil 61 is shaped as an "S" on the shell 10. "-shaped wiring, the heating medium rapidly twists and turns in the upper coil 61, so that the heating medium preferably forms a turbulent state in the upper coil 61, which has a better heat transfer effect. The heating medium enters the lower coil 62 from a low level and flows out of the upper coil 61 from a high level. The heating medium spirally rises along the lower coil 62. The flow radius of the heating medium at the lower end of the lower coil 62 is small, the temperature is high, and the heat transfer is poor. The flow radius of the heating medium at the lower end of the upper coil 61 is large, the temperature is low, and the heat transfer is good. The heating temperature of the lower part of the cavity by the lower coil 62 is relatively consistent with the heating temperature of the upper part of the cavity by the upper coil 61.

[0044] The modules or units in the device of the embodiment of the present utility model can be combined, divided and deleted according to actual needs.
