Description

Technical Field

[0001] The utility model relates to the field of dryers, and particularly to a dryer with an energy-saving structure. Background Art

[0002] Dryers are mainly used to dry particulate matter (such as plastic particles) to remove moisture. The current existing technical solution is to introduce air at the bottom and discharge it at the top. Therefore, the heat transfer efficiency is relatively low, and the heat preservation performance is poor. As a result, the heating time inside the container needs to be long to maintain a constant temperature. A long processing time requires a relatively high power, and thus the energy consumption is also large. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose a dryer with an energy-saving structure, aiming to improve the structure of the dryer, thereby realizing the circulation of temperature, while being structurally compact, effectively reducing energy consumption, and improving the energy-saving effect.

[0004] To achieve the above object, the utility model proposes a dryer with an energy-saving structure, including:

[0005] A cylinder, the cylinder is a cavity with an accommodation space inside, and a cavity air outlet and a cavity air inlet are respectively provided at the upper and lower parts of the cylinder;

[0006] A hot air assembly, the hot air assembly includes a fan and a heating pipe connected to the fan. The fan is provided with a blowing outlet and a blowing inlet. The heating pipe includes an inner pipe and an outer pipe. The inner pipe is provided with a first channel, and a second channel is formed between the inner pipe and the outer pipe. The second channel is provided with an external air inlet and an external air outlet.

[0007] A heating device is arranged in the first channel.

[0008] The outlet of the inner pipe is connected to the cavity air inlet, and the inlet of the inner pipe is connected to the blowing outlet.

[0009] The blowing inlet is connected to the outlet of the outer flow channel.

[0010] A filter, the filter is used to remove moisture and fine particles in the air. The filter is provided with a filter outlet and a filter inlet. The filter inlet is connected to the cavity air outlet, and the cavity air outlet is connected to the external air inlet.

[0011] In actual design, air sequentially passes through the heating device in the first channel, the cylinder, the filter, the second channel, and the fan under the blowing of the fan, forming a circulating flow of hot air, and realizing the recovery of heat energy, effectively avoiding the waste of heat energy. At the same time, the cooperation of the inner pipe and the outer pipe forms an air barrier, which also effectively plays a role in heat preservation, avoiding the waste of heat energy of the heating device, and effectively improving the energy efficiency utilization rate.
