DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in the embodiments of the present application in combination with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0029] Please refer to Figures 1-2 ​The application provides a cooling device for chemical reagent test, which comprises an inner tank 1, an outer shell 2 arranged on the outer peripheral side of the inner tank 1 and forming a cooling chamber with the inner tank 1, a stirring member 3 and an inner cooling circulation member 4.

[0030] The stirring member 3 comprises two hollow shafts 31 rotating at the two ends of the inner tank 1 respectively, and a spiral pipe 32 in common communication with the opposite ends of the two hollow shafts 31; and a driving member 33 is arranged at the top of the inner tank 1 and used to drive the hollow shafts 31 to rotate.

[0031] The inner cooling circulation member 4 comprises a liquid inlet member 42 rotatingly connected to the top of the upper hollow shaft 31 and to the top of the outer shell 2, and a liquid outlet member 43 rotatingly connected to the bottom of the lower hollow shaft 31 and used to discharge the liquid in the outer shell 2.

[0032] In the embodiment, the chemical reagent is put into the inner tank 1, the driving member 33 is started to drive the spiral pipe 32 connected by the two hollow shafts 31 to agitate the chemical reagent, and the cooling liquid is sequentially delivered to the two flow directions in the gap between the upper hollow shaft 31 and the outer shell 2 and the inner tank 1 through the liquid inlet member 42; the cooling liquid passing through the upper hollow shaft 31 flows out from the liquid outlet member 43 through the spiral pipe 32 and the lower hollow shaft 31; and the cooling liquid in the gap slowly flows out from the liquid outlet member 43. The design that the same water cooling circulation mechanism is arranged on the inner and outer sides of the inner tank 1 at the same time can improve the water cooling effect of the chemical reagent and reduce the use cost of the water cooling circulation mechanism to a certain extent.

[0033] Please refer to Figure 5 The driving member 33 comprises a servo motor 331 mounted to one side of the top of the inner tank 1, a rotating shaft 332 connected to the output end of the servo motor 331, and gear wheels 333 arranged on the upper hollow shaft 31 and the rotating shaft 332 and capable of meshing with each other. Specifically, the servo motor 331 is started to drive the rotating shaft 332 to rotate, so that the two meshing gear wheels 333 rotate indirectly, thereby driving the upper hollow shaft 31 and the spiral pipe 32 and the lower hollow shaft 31 to rotate, facilitating the agitation of the chemical reagent in the inner tank 1 and the rapid increase of the contact area between the chemical reagent and the cooling liquid.

[0034] Please refer to Figure 5The liquid inlet member 42 comprises a liquid inlet sub-pipe A 421 connected to the top of the upper hollow shaft 31 and a liquid inlet sub-pipe B 422 connected to the top of the outer shell 2, and the liquid inlet sub-pipe A 421 and the liquid inlet sub-pipe B 422 are jointly connected to a liquid inlet main pipe 423. Specifically, the external water inlet pipe is connected to the liquid inlet main pipe 423, and the external cooling liquid flows into the liquid inlet main pipe 423, and then flows into the liquid inlet sub-pipe A 421 and the liquid inlet sub-pipe B 422 in sequence, and the cooling liquid flowing into the liquid inlet sub-pipe A 421 flows through the upper hollow shaft 31, the lower spiral pipe 32 and the lower hollow shaft 31 and is discharged through the liquid outlet member 43; the cooling liquid flowing into the liquid inlet sub-pipe B 422 is discharged through the liquid outlet member 43, thereby realizing synchronous water cooling inside and outside the inner tank 1.

[0035] The inner top of the upper hollow shaft 31 is fixed with a bearing A (not shown), and the inner ring of the bearing A is fixed with the outer wall of the liquid inlet sub-pipe A 421. Specifically, the design of the bearing A can make the hollow shaft 31 and the liquid inlet sub-pipe A 421 rotate and connect with each other, and can also ensure that the inner cavities of the two are communicated.

[0036] Please refer to Figures 1-4 The liquid outlet member 43 comprises a fixed seat 431 fixed to the middle bottom of the inner tank 1, and the fixed seat 431 is provided with a cavity 4311 connected to the lower hollow shaft 31, and the fixed seat 431 is horizontally connected to a drainage sub-pipe A 432 connected to the cavity 4311 and extending to the outside of the outer shell 2, and the outer bottom of the outer shell 2 is connected to a drainage sub-pipe B 433, and the drainage sub-pipe A 432 and the drainage sub-pipe B 433 are jointly connected to a drainage main pipe 434. Specifically, the cooling liquid flowing out of the lower hollow shaft 31 flows through the cavity 4311, the drainage sub-pipe A 432 and the drainage main pipe 434 in sequence, and is finally discharged, and the cooling liquid in the cavity between the inner tank 1 and the outer shell 2 flows from the drainage sub-pipe B 433 and the drainage main pipe 434 in sequence, and is also finally discharged.

[0037] Please refer to Figure 4 The inner wall of the cavity 4311 is provided with a sealing rubber ring abutting against the outer wall of the lower hollow shaft 31. Specifically, the design of the sealing rubber ring can increase the sealing effect when the hollow shaft 31 is connected to the fixed seat 431.

[0038] Please refer to Figure 1 , Figure 2 and Figure 6 The chemical reagent test cooling device further comprises a air cooling member 5;

[0039] The air cooling member 5 comprises a hollow arc-shaped plate 51 connected to the top of the inner tank 1, and the top of the hollow arc-shaped plate 51 is connected to a connecting plate 52, and the top of the connecting plate 52 is fixed with a heat dissipation pipe 53, and the heat dissipation pipe 53 is provided with a heat dissipation fan 54.

[0040] The top of the inner tank 1 has an arc-shaped groove 11 that communicates with the inner cavity of the hollow arc-shaped plate 51. Specifically, when the cooling fan 54 is turned on, the heat inside the inner tank 1 is discharged to the outside through the arc-shaped groove 11 and the hollow arc-shaped plate 51 in sequence. This can be combined with water cooling to accelerate the cooling effect of the chemical reagent.

[0041] In addition, the combined design of the arc-shaped groove 11 and the hollow arc-shaped plate 51 can increase the area of ​​air-cooled heat dissipation and further accelerate the cooling of chemical reagents.

[0042] Please see Figure 2 The inner tank 1 has a feed inlet at the top and a discharge outlet extending to the outside of the outer shell 2 at the bottom, with a gate valve on the discharge outlet. Specifically, the design of the feed inlet and discharge outlet allows for the inflow and outflow of chemical reagents.

[0043] When this application is used:

[0044] Chemical reagents are fed into the inner tank 1 through the inlet. Activating the servo motor 331 drives the rotating shaft 332 to rotate, indirectly causing two meshing gears 333 to rotate. This drives the upper hollow shaft 31, the lower spiral tube 32, and the lower hollow shaft 31 to rotate, facilitating the agitation of the chemical reagents within the inner tank 1. Simultaneously, external coolant flows through the main inlet pipe 423 to the inlet branch pipes A421 and B422. The coolant flowing into branch pipe A421 passes through the upper hollow shaft 31, the lower spiral tube 32, and the lower hollow shaft 31, and is discharged through the drain branch pipe A432 and the main drain pipe 434. The coolant flowing into branch pipe B422 is discharged through the drain branch pipe B433 and the main drain pipe 434. This design allows the inner tank 1 to have the same water-cooling circulation mechanism on both the inner and outer sides, improving the water-cooling effect of the chemical reagents while also reducing the operating cost of the water-cooling circulation mechanism to some extent.

[0045] While water cooling is in operation, the heat dissipation fan 54 is turned on to expel the heat inside the inner tank 1 to the outside through the arc-shaped groove 11 and the hollow arc-shaped plate 51. This can be combined with water cooling to accelerate the cooling effect of chemical reagents.

[0046] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
