Description

Technical Field

[0001] The utility model relates to the technical field of cheese drying, in particular to a fin-type heat exchanger group used for a cheese drying machine. Background Art

[0002] The cheese yarn is a cylindrical yarn ball wound by yarn. It can maintain a certain shape and density during the dyeing process, so that the dye can evenly penetrate into the yarn, thereby achieving uniform dyeing. This kind of yarn ball is usually drawn from the creel, passed through the tension device, yarn guide and winding device, and finally wound into a cylindrical shape. The cheese yarn needs to be dried during preparation. The heat exchanger and condenser of the unloading-free cheese yarn dryer on the market are all tube-in-tube structures. Since most of the heat medium is steam, the hot air heated for drying the cheese yarn is air.

[0003] However, due to the low heat conduction efficiency of steam and air, the heat exchange area of ​​the shell-and-tube structure is smaller than that of the fin-type heat exchanger of the same specification, resulting in low heat exchange efficiency and insufficient evaporation, which greatly reduces the working efficiency of the dryer. Utility Model Content

[0004] The purpose of the utility model is to provide a fin-type heat exchanger group for a cheese yarn dryer, aiming to solve the technical problems in the prior art that the heat conduction efficiency of steam and air is low, the heat exchange area of ​​the shell and tube structure is smaller than that of the fin-type heat exchanger of the same specification, resulting in low heat exchange efficiency and insufficient evaporation, which greatly reduces the working efficiency of the dryer.

[0005] To achieve the above-mentioned purpose, the utility model adopts a fin-type heat exchanger group for a cheese yarn dryer, comprising a dryer body, a cheese yarn rack, an air inlet assembly, a return air assembly and a fan, the cheese yarn rack is arranged on the dryer body, the cheese yarn rack has cheese yarn, the air inlet assembly and the return air assembly are both connected to the dryer body, and the fan is arranged on the air inlet assembly and the return air assembly.

[0006] Among them, the air inlet assembly includes an air inlet pipe, at least one group of heating heat exchanger groups and a first connecting pipe, the air inlet pipe is connected to the dryer body, the first connecting pipe is connected to the fan, the heating heat exchanger group is arranged between the air inlet pipe and the first connecting pipe, and the heating heat exchanger group is provided with at least one steam inlet and at least one condensate outlet.

[0007] Among them, the return air assembly includes a return air duct, at least one group of cooling heat exchanger groups and a second connecting pipe, the return air duct is also connected to the dryer body, the second connecting pipe is connected to the fan, the cooling heat exchanger group is arranged between the return air duct and the second connecting pipe, and the cooling heat exchanger group is provided with at least one cooling water inlet and at least one cooling water outlet.

[0008] Wherein, the temperature-raising heat exchanger group includes at least one heat exchange tube and a plurality of flaps, the plurality of flaps are arranged on the heat exchange tube, and the heat exchange tube is arranged between the air inlet tube and the first connecting tube.

[0009] Wherein, the fin-type heat exchanger group for the cheese yarn dryer also includes two U-shaped plates, and the two U-shaped plates are both connected to the dryer body.

[0010] The utility model discloses a fin-type heat exchanger group for a cheese yarn dryer. When in use, the cooling heat exchanger group has the same structure as the heating heat exchanger group. The cheese yarn carrying residual liquid after dyeing is put into the dryer body together with the cheese yarn rack. At this time, the fan is started, and the heating heat exchanger group begins to pass steam or heat transfer oil from the steam inlet. The heated gas enters the cheese yarn rack through the air inlet pipe under the action of the fan and passes through the cheese yarn to heat the cheese yarn. The steam generated after the cheese yarn is heated is released into the dryer body together with the air. The steam is extracted through the return air duct, and cold water (or other low-temperature liquid) is introduced into the cooling water inlet when passing through the cooling heat exchanger group. When the high-temperature steam encounters the cooling heat exchanger group, it condenses into liquid water and is discharged from the drain port of the cooling heat exchanger group. At the same time, the cold water that has completed the heat exchange is discharged from the cooling water outlet to complete the drying of the cheese yarn. In this way, the technical problem in the prior art that the heat conduction efficiency of steam and air is low, the heat exchange area of ​​the shell and tube structure is smaller than that of the fin-type heat exchanger of the same specification, resulting in low heat exchange efficiency, insufficient evaporation, and greatly reduced working efficiency of the dryer is solved.

[0022] In this embodiment, when in use, the cooling heat exchanger group 8 has the same structure as the heating heat exchanger group 5, and the cheese 17 carrying the residual liquid after dyeing is placed in the dryer body 1 together with the cheese creel 2. At this time, the fan 3 is started, and the heating heat exchanger group 5 begins to pass steam or heat transfer oil from the steam inlet. The heated gas enters the cheese creel 2 through the air inlet pipe 4 under the action of the fan 3 and passes through the cheese 17 to heat the cheese 17. The steam generated after the cheese 17 is heated is released into the dryer body 1 together with the air, and the steam or heat transfer oil is passed through the cheese creel 2 under the action of the fan 3. The return air duct 7 is drawn out, and cold water (or other low-temperature liquid) is introduced into the cooling water inlet 15 when passing through the cooling heat exchanger group 8.

At this time, the fan 3 is started, and the heating heat exchanger group 5 begins to pass steam or heat transfer oil from the steam inlet. The heated gas enters the cheese creel 2 through the air inlet pipe 4 under the action of the fan 3 and passes through the cheese 17 to heat the cheese 17. The steam generated after the cheese 17 is heated is released into the dryer body 1 together with the air, and the steam or heat transfer oil is passed through the air inlet pipe 4 under the action of the fan 3. The steam is extracted through the return air duct 7, and cold water (or other low-temperature liquid) is introduced into the cooling water inlet 15 when passing through the cooling heat exchanger group 8.
