Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling devices, in particular to a closed cooling device for a dosing device. Background Art

[0002] The closed cooling device adopts a fully enclosed circulating cooling method, which effectively prevents sundries from entering the cooling pipeline system, avoids pipeline blockage, and at the same time, the device will not produce scale at high temperatures, ensuring the cleanliness of the cooling pipeline system.

[0003] The existing closed cooling device generally installs the conveying pipeline in the housing, and the conveyed medium flows through the conveying pipeline, and then the cooling device sprays the coolant onto the surface of the conveying pipeline to cool the internal medium. However, since the conveying pipeline is fixed inside the housing, when it is necessary to clean the surface of the conveying pipeline, the staff needs to remove the conveying pipeline from the housing for cleaning, which is troublesome. Moreover, when the closed cooling device is cooling, the coolant is recycled, resulting in impurities in the coolant circulating with the coolant during use, and thus easily colliding with the outer surface of the conveying pipeline, easily causing damage to the conveying pipeline and poor use effect. For this reason, we propose a closed cooling device for a dosing device. Content of the Utility Model

Detailed Description of the Preferred Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1-4 , a closed cooling device for a dosing device includes an outer shell 1 with an opening on one side. A partition board 12 is provided inside the outer shell 1, and the edge of the partition board 12 is fixed on the inner wall of the outer shell 1. The inner part of the outer shell 1 can be divided into two parts by the partition board 12. The part below the partition board 12 is a water storage tank, and the part above the partition board 12 is a cooling chamber.

[0027] As shown in Figure 1 and Figure 3 , a pair of support rods 19 are symmetrically provided on both sides of the top of the partition board 12. Both ends of each pair of support rods 19 are connected by a strip-shaped connecting plate 18. Strip-shaped support plates 6 are installed on both sides inside the outer shell 1. One side of each strip-shaped support plate 6 extends above the support rod 19, and a pair of strip-shaped limiting plates 14 are installed at the bottom of each strip-shaped support plate 6 and on both sides of the top of the partition board 12. A receiving groove is formed between each pair of strip-shaped limiting plates 14, and the strip-shaped connecting plates 18 are all located in the corresponding receiving grooves. During actual use, the support rods 19 and the strip-shaped connecting plates 18 can be pulled out of the outer shell 1 along the strip-shaped limiting plates 14.

[0028] It should be noted that, as Figure 3 shown, at the top end of each of the two pairs of strip-shaped limiting plates 14 located below, a limiting block 27 is installed. The limiting block 27 is located between two support rods 19 on the same side. In this way, when the support rods 19 and the strip-shaped connecting plate 18 are pulled out of the housing 1, the limiting block 27 will block the support rods 19, and the strip-shaped connecting plate 18 can be prevented from detaching from the limiting block 27.

[0029] As Figure 1 and Figure 3 shown, a number of strip-shaped fixing plates 20 are stacked and installed on the support rods 19 on the same side, and a heat exchange tube 5 is installed at the top of each pair of strip-shaped fixing plates 20. The adjacent two heat exchange tubes 5 are connected end to end. One end of the heat exchange tube 5 located at the uppermost part is connected to a medicine inlet pipe 7 through a pipe joint. One end of the medicine inlet pipe 7 extends to the outside of the housing 1. One end of the heat exchange tube 5 located at the lowermost part is connected to a medicine discharge pipe 9 through a pipe joint. One end of the medicine discharge pipe 9 extends to the outside of the housing 1. During actual use, the dosing device will transport the liquid medicine into the heat exchange tube 5 through the medicine inlet pipe 7, and after cooling and heat dissipation, it will be discharged through the medicine discharge pipe 9.

[0030] It should be noted that, as Figure 3 shown, the heat exchange tube 5 is arranged in an "S" shape or a serpentine shape, which can increase the flow distance and time of the liquid medicine in the heat exchange tube 5, so that the cooling liquid can fully cool the liquid medicine in the heat exchange tube 5.

[0031] As Figure 2 and Figure 4 shown, a mounting seat 25 is installed on one side of the bottom of the housing 1. A delivery pump 23 is installed on the mounting seat 25. The liquid inlet of the delivery pump 23 is connected to a liquid inlet pipe 24. One end of the liquid inlet pipe 24 extends to the bottom end inside the housing 1. The liquid outlet of the delivery pump 23 is connected to an infusion pipe 22. One end of the infusion pipe 22 penetrates through the side surface at the top of the housing 1 and is connected to the side surface of the liquid collecting pipe 13, and the liquid collecting pipe 13 is fixed on the side wall at the top end inside the housing 1. A number of spray pipes 26 are installed on the other side of the liquid collecting pipe 13. The other end of the spray pipe 26 is fixed on the side surface of the housing 1, and a number of spray heads 28 are installed at the bottom of each spray pipe 26. The spray heads 28 are located above the heat exchange tube 5, and the spray nozzles of the spray heads 28 face the heat exchange tube 5. During actual use, the delivery pump 23 can transport the cooling liquid at the bottom of the housing 1 into the liquid collecting pipe 13 through the liquid inlet pipe 24 and the infusion pipe 22, and finally spray it onto the heat exchange tube 5 through the spray heads 28 below the spray pipes 26 to cool the liquid medicine flowing in the heat exchange tube 5.

[0032] As Figure 1 and Figure 2As shown, a plurality of drain grooves 11 are provided at the top of the partition plate 12. The coolant sprayed by the nozzle 28 will fall on the partition plate 12 under the action of gravity after cooling the liquid medicine in the heat exchange tube 5, and finally flow into the bottom of the housing 1 along the drain grooves 11 for recycling.

[0033] It should be noted that, as Figure 3 shown, the top of the strip-shaped support plate 6 is inclined. In this way, part of the coolant sprayed by the nozzle 28 will fall on the strip-shaped support plate 6, and then flow onto the heat exchange tube 5 along the inclined surface at the top of the strip-shaped support plate 6, which can avoid the coolant remaining on the strip-shaped support plate 6.

[0034] As Figure 1 and Figure 2 shown, at least one mounting opening 3 is provided at the top of the housing 1. A fan 4 is rotatably connected to the inside of the mounting opening 3 through a bracket. The top of the fan 4 is connected to the drive motor 2, and the drive motor 2 is fixed on the bracket. An air inlet 8 is provided on one side of the housing 1. During actual use, the drive motor 2 can drive the fan 4 to rotate, so that the fan 4 sucks out the air inside the housing 1. In this way, when cooling the liquid medicine in the heat exchange tube 5, the external air can flow to the bottom of the housing 1 through the air inlet 8. At the same time, the coolant falls into the bottom of the housing 1 under the action of gravity. In this way, the air flowing into the housing 1 through the air inlet 8 can cool the coolant, and then be discharged from the housing 1 through the fan 4.

[0035] It should be noted that one side of the housing 1 is connected with a baffle 21 through a hinge. The other end of the baffle 21 is fixed on the housing 1 through a buckle, and the baffle 21 is in sealed cooperation with the edge of the housing 1. The opening of the housing 1 can be blocked by the baffle 21. In this way, when cooling the liquid medicine, the coolant inside the housing 1 will not leak into the external environment, and under the action of the fan 4, the external air will also flow into the housing 1 through the air inlet 8 to fully dissipate the heat of the coolant.

[0036] As Figure 1 and Figure 2 shown, L-shaped support frames 10 are installed on both sides of the bottom of the partition plate 12. A frame 17 is provided between the two L-shaped support frames 10. A filter screen 15 is installed inside the frame 17, and the filter screen 15 is located below the drain grooves 11. A mounting plate 16 is provided on one side of the bottom of the housing 1, and the mounting plate 16 is installed on the housing 1. When the mounting plate 16 is fixed on the housing 1, one side of the frame 17 is in sealed contact with the side surface of the mounting plate 16. During actual use, the mounting plate 16 is fixed on the housing 1 through bolts. In this way, the opening of the water storage tank formed between the bottom of the housing 1 and the bottom of the partition plate 12 can be blocked, and the cooled coolant can be filtered through the filter screen 15 to filter out the impurities on the coolant.

[0037] Specifically, when the utility model is in use, the staff transports the liquid medicine in the medicine adding device to the heat exchange tube 5 in the outer shell 1 through the medicine inlet pipe 7. The liquid medicine flows along the heat exchange tube 5. At the same time, the staff controls the delivery pump 23 and the driving motor 2 to work. The delivery pump 23 can transport the coolant in the liquid storage tank at the bottom of the outer shell 1 to the liquid collecting pipe 13 through the liquid inlet pipe 24 and the liquid delivery pipe 22, and then transport it to the spray pipe 26 through the liquid collecting pipe 13. Finally, the coolant is sprayed onto the surface of the heat exchange tube 5 through the nozzle 28 to cool the liquid medicine in the heat exchange tube 5. At the same time, the driving motor 2 drives the fan 4 to rotate, exhausting the air in the outer shell 1, causing negative pressure inside the outer shell 1. The air inlet 8 generates suction, sucking the outside air into the bottom end of the outer shell 1. While the air flows towards the fan 4, it cools the coolant. The cooled coolant flows through the drainage groove 11 into the water storage tank at the bottom of the outer shell 1. During the process of flowing into the water storage tank, the coolant flows onto the filter screen 15, and the impurities in the coolant are filtered out by the filter screen 15. The air flowing into the outer shell 1 is discharged from the installation opening 3. And the liquid medicine cooled by the coolant flows along the heat exchange tube 5 into the medicine discharge pipe 9 and is discharged to the next process along the medicine discharge pipe 9. When it is necessary to clean the surface of the heat exchange tube 5, the staff can rotate the baffle 21 to open the opening of the outer shell 1. Then the staff separates the ends of the medicine inlet pipe 7 and the medicine discharge pipe 9 from the ends of the heat exchange tube 5. After that, the staff pulls the support rod 19, making the strip-shaped connecting plate 18 move along the strip-shaped limiting plate 14, moving the heat exchange tube 5 out of the outer shell 1, and then it is convenient to clean the surface of the heat exchange tube 5, and the cleaning is convenient.

[0038] Furthermore, as Figure 1 shown, the top of the filter screen 15 is lower than the top of the frame 17. A receiving groove is formed between the top of the injection filter screen 15 and the top of the frame 17, so that the coolant will not overflow the frame 17 during filtration, making the filtration sufficient.

[0039] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
