Description

Technical Field

[0001] This application relates to the field of dryers, and in particular to a cooling system for a pulse dryer. Background Art

[0002] The pulse air flow dryer is a large - batch drying equipment. It adopts the principle of instant drying. By using the rapid movement of the heat - carrying air to drive the wet materials, the wet materials are suspended in the hot air, which strengthens the entire drying process, improves the heat and mass transfer rate. For the materials dried by the air flow drying, almost all the unbound moisture can be removed, and the dried materials will not deteriorate. The output can be significantly increased compared with that of general dryers. After drying, the temperature of the materials is relatively high and needs to be cooled. Using air cooling or fan cooling methods, the cooling time is relatively long, which greatly reduces the overall efficiency of the material preparation process. Utility Model Content

[0026] The following further describes the present application in conjunction with the attached Figure 1 drawings for a more detailed description.

[0027] The embodiment of the present application discloses a cooling system for a pulse dryer. As Figure 1 shown, the arrows in the figure indicate the water flow direction, including a drying device 1, a chiller 2 and a first cold water tank 21. A jacket 15 is sleeved on the drying device 1, and a channel 151 is provided in the jacket 15. A first water inlet pipe 11 and a first water outlet pipe 12 are connected to the drying device 1. Both the first water inlet pipe 11 and the first water outlet pipe 12 are communicated with the internal water pipes of the drying device 1 and also with the channel 151. A water pump is installed on the first water inlet pipe 11. One end of the first water inlet pipe 11 away from the drying device 1 is connected to the first cold water tank 21, and one end of the first water outlet pipe 12 away from the drying device 1 is connected to the first cold water tank 21. The chiller 2 is connected to the first cold water tank 21 through a pipeline. The cooling water in the chiller 2 can enter the first cold water tank 21 through the pipeline. When it is necessary to cool down the drying device 1, the operator can drive the water pump to make the water in the first cold water pipe flow into the internal water pipes and the channel 151 of the drying device 1 through the first water inlet pipe 11, and reduce the temperature of the drying device 1 by reducing the temperature of the internal water pipes of the drying device 1 and the temperature of the jacket 15, and the water can flow back into the first cold water tank 21 through the first water outlet pipe 12 to realize the circulation of the cooling water.

[0028] As Figure 1As shown in the figure, it further includes a second cold water tank 22 and a condenser 23. The water chiller 2 is connected to the second cold water tank 22 through a pipeline, and the water chiller 2 is connected to the condenser 23 through a pipeline; there is a pipeline connection between the first cold water tank 21 and the condenser 23, and there is a pipeline connection between the second cold water tank 22 and the condenser 23. The pipeline between the first cold water tank 21 and the condenser 23 is communicated with the pipeline between the second cold water tank 22 and the condenser 23. The cooling water in the water chiller 2 flows into the second cold water tank 22 and flows back into the water chiller 2 through the condenser 23. The condenser 23 can cool the condensed water to make the cooling water reach the specified temperature; the cooling water in the first cold water tank 21 can also flow back into the cooling water group through the condenser 23 to realize the self-circulation of the cooling water, which is convenient for the cooling water in the first cold water tank 21 to cool the drying device 1.

[0029] As Figure 1 shown in the figure, it further includes a makeup water tank 3. A makeup water pipe 33 is connected to the makeup water tank 3, and a makeup water valve 331 is installed on the makeup water pipe 33. The operator can open the makeup water valve 331 to add water to the makeup water tank 3 through the makeup water pipe 33. A second water inlet pipe 31 and a second water outlet pipe 32 are connected to the makeup water tank 3. One end of the second water inlet pipe 31 away from the makeup water tank 3 is communicated with the internal water pipe of the drying device 1, and one end of the second water outlet pipe 32 away from the makeup water tank 3 is communicated with the first water inlet pipe 11. A cold water valve 111 and a pipeline heater 13 are installed on the first water inlet pipe 11. A heating pipe 14 is connected to the pipeline heater 13, and a heating valve 141 is provided on the heating pipe 14. Industrial steam enters from one end of the heating pipe 14 away from the pipeline heater 13. When the drying device 1 needs to increase the temperature, the operator closes the cold water valve 111 to block the cooling water from flowing into the first water inlet pipe 11. Then the water in the makeup water tank 3 flows into the second water outlet pipe 32 and flows into the first water inlet pipe 11 from the second water outlet pipe 32. The heating valve 141 is opened to make industrial steam enter the heating pipe 14, thereby heating the water in the first water inlet pipe 11. The heated water flows into the internal water pipe of the drying device 1 and flows out from the second water inlet pipe 31 and returns to the makeup water tank 3 to realize the circulation of hot water, which is convenient for increasing the temperature inside the drying device 1.

[0030] As Figure 1As shown, the second water inlet pipe 31 is connected to the first water outlet pipe 12, and a first valve 121 is installed on the first water outlet pipe 12, and a second valve 311 is installed on the second water inlet pipe 31. When the temperature of the drying equipment 1 needs to be increased, the operator needs to open the second valve 311 and close the first valve 121. At this time, the water in the water pipe of the drying equipment 1 flows into the second water inlet pipe 31 through the first water outlet pipe 12, and then flows into the water supply tank 3 through the second water inlet pipe 31, realizing the circulation of hot water. When the drying equipment 1 needs to be cooled, the operator needs to open the first valve 121 and close the second valve 311. At this time, the water in the water pipe of the drying equipment 1 flows into the first cold water tank 21 through the first water outlet pipe 12, realizing the circulation of cooling water.

[0031] like Figure 1 As shown, a return pipe 34 is connected to the water supply tank 3. The end of the return pipe 34, away from the water supply tank 3, is connected to the drying apparatus 1. A return valve 341 and a water pump are installed on the return pipe 34. When the drying apparatus 1 is not in use, the water in the drying apparatus 1 can be returned to the water supply tank 3. The operator opens the return valve 341 and activates the water pump to draw water out of the water pipe of the drying apparatus 1 and flow it into the water supply tank 3 through the return pipe 34.

[0032] The implementation principle of the pulse dryer cooling system in the embodiment of the present application is as follows:

[0033] When the drying device 1 needs to be cooled, the operator drives the water pump, and the water in the first cold water tank 21 enters the internal water pipe and channel 151 of the drying device 1 through the first water inlet pipe 11, and flows back to the first cold water tank 21 through the first water outlet pipe 12, thus realizing the circulation of cooling water. When the drying device 1 needs to be heated, the operator closes the cold water valve 111 and opens the heating valve 141, and the water in the water supply tank 3 flows into the first water inlet pipe 11 through the second water outlet pipe 32. The pipeline heater 13 can heat the water in the first water inlet pipe 11, and then transport it to the drying device 1 through the water pump and flow into the drying device 1 through the first water outlet pipe 12. At this time, the second valve 311 is opened and the first valve 121 is closed, so that the water in the first water outlet pipe 12 flows into the second water inlet pipe 31, and then flows into the water supply tank 3 through the second water inlet pipe 31, thus realizing the circulation of hot water.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
