Description

Technical Field

[0001] The utility model relates to the technical field of cheese drying, in particular to a cheese unloading-free yarn drying machine equipped with a Roots blower. 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, thus 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 fans of the unloading-free cheese yarn dryer on the market are all centrifugal fans. The output wind pressure of ordinary centrifugal fans is generally below 10Kpa.

[0003] However, due to the high density of the cheese yarn after dyeing, the wind pressure provided by the ordinary centrifugal fan cannot effectively overcome the resistance of the cheese yarn spindle and penetrate the cheese yarn spindle. The air volume passing through the spindle is very low, which greatly reduces the drying efficiency. Utility Model Content

[0004] The utility model aims to provide a cheese yarn unloading-free yarn dryer equipped with a Roots blower, aiming to solve the technical problem in the prior art that the density of the cheese yarn after dyeing is relatively large, the wind pressure provided by the ordinary centrifugal fan cannot effectively overcome the resistance of the cheese yarn spindle and penetrate the cheese yarn spindle, the air volume passing through the spindle is very low, and the drying efficiency is greatly reduced.

[0005] To achieve the above-mentioned purpose, the utility model adopts a cheese yarn unloading-free yarn dryer equipped with a Roots blower, comprising a dryer main body, a supporting frame, an air inlet pipe, a temperature rising heat exchange component, an air outlet pipe, a temperature falling heat exchange component, an air filter, a Roots blower and a connecting pipe, wherein the supporting frame is arranged in the dryer main body, the supporting frame is used to carry the cheese yarn, one end of the air inlet pipe is connected to the temperature rising heat exchange component, the other end of the air inlet pipe is inserted into the dryer main body and communicated with the internal space of the supporting frame, one end of the air outlet pipe is communicated with the dryer main body, the other end of the air outlet pipe is connected to the air filter, the two ends of the connecting pipe are respectively connected to the air filter and the temperature falling heat exchange component, a filter screen is arranged in the air filter, and the Roots blower is arranged between the temperature rising heat exchange component and the temperature falling heat exchange component.

[0006] Wherein, the cooling and heat exchanging component is provided with a drain outlet.

[0007] Wherein, the cheese yarn unloading-free yarn dryer equipped with a Roots blower also includes a support member, and the support member is fixedly connected to the dryer body.

[0008] The temperature-increasing heat exchange component includes a temperature-increasing heat exchanger and a first tube body, the temperature-increasing heat exchanger is connected to the air inlet pipe, and two ends of the first tube body are respectively connected to the temperature-increasing heat exchanger and the Roots blower.

[0009] The cooling and heat exchanging assembly includes a cooling and heat exchanging device and a second tube body. The cooling and heat exchanging device is connected to the air outlet pipe, and two ends of the second tube body are respectively connected to the cooling and heat exchanger and the Roots blower.

[0010] The utility model discloses a cheese yarn unloading-free yarn dryer equipped with a Roots blower. When it is used, the cheese yarn carrying residual liquid after dyeing is placed in the dryer body together with the supporting frame. At this time, the Roots blower is started, and the heating heat exchanger component starts to heat the air. The heated gas enters the supporting frame through the air inlet pipe under the action of the Roots blower 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, and is drawn out through the air outlet pipe under the action of the Roots blower. The impurities in the gas are filtered through the air filter and then cooled through the cooling heat exchanger component. When the high-temperature steam encounters the cooling heat exchanger component, it condenses into liquid water and is discharged from the drain port to complete the drying of the cheese yarn. In this way, the technical problem that the cheese yarn density after dyeing is relatively large, the wind pressure provided by the ordinary centrifugal fan cannot effectively overcome the resistance of the cheese yarn spindle to penetrate the cheese yarn spindle, the air volume passing through the spindle is very low, and the drying efficiency is greatly reduced in the prior art is solved.
