Description

Technical Field

[0001] The invention relates to the technical field of dehumidification and drying equipment, and in particular to a dehumidification and drying equipment for raw materials of gas pipes. Background Art

[0002] The raw materials for gas pipes need to be dried before entering the gas pipe processing to ensure that there is no water vapor in the raw materials. Therefore, dehumidification and drying equipment for raw materials for gas pipes will be used;

[0003] The existing publication number CN110455053B discloses a chemical raw material drying device with a chemical raw material stirring function. The chemical raw material drying device realizes full contact with hot air by setting a stirring shaft in a drying tower body to improve the drying effect and drying efficiency. However, due to the existence of saturated vapor pressure, high-speed circulating hot air is the key to the drying effect and drying efficiency. The contact time between the raw materials in the drying tower body and the hot air is short, and the hot air is directly discharged to the external environment after drying the raw materials, resulting in energy waste and increasing the cost of raw material drying. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a dehumidification and drying equipment for raw materials for gas pipes. Through the raw material drying tower, the raw materials for gas pipes can be put into the feed hopper, and then the two dividing mechanisms on the bottom of the feed hopper quantitatively divide the raw materials for gas pipes and transport them to the spiral drying tube. The dividing mechanism can prevent the uneven feeding of the quantitatively divided raw materials from causing blockage or uneven drying of the spiral drying tube. The set discharging mechanism can transfer the quantitatively divided raw materials dried on the bottom of the spiral drying tube out of the spiral drying tube, and the set dividing mechanism and discharging mechanism can simultaneously ensure that the two ends of the spiral drying tube are relatively sealed, thereby ensuring that the hot air can flow in the spiral drying tube without loss. The spiral drying tube can increase the contact time between the hot air transported by the air inlet pipe and the raw materials, thereby improving the drying effect. The set air outlet pipe can recycle the hot air, thereby reducing energy loss.
