Plastic liner drying tank

Abstract

The invention discloses a plastic inner container drying groove which comprises a supporting frame made of PVDF profiles, a heating box and a groove body which are communicated with each other are horizontally arranged on the upper side of the supporting frame side by side, a fan located outside the heating box and the groove body is further installed on the supporting frame, and an air inlet of the fan is communicated to an air outlet of the groove body through an air pipe. An air outlet of the fan is communicated to an air inlet of the heating box through an air pipe; an inner container made of PVDF materials is arranged on the inner wall of the tank body, and a cover plate capable of being opened and closed is arranged on the upper side of the tank body. The supporting frame and the inner container of the tank body are both made of PVDF materials, so that the manufacturing cost and the corrosion resistance of the drying tank are effectively reduced; the space in the tank body is effectively released by the independent external heating box; after the fan is externally arranged, a large-air-volume fan can be used for increasing the air speed so as to realize rapid temperature rise and stable working temperature.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a plastic liner drying tank. Background technique [0002] Many products need to use drying equipment for drying in the production and processing process, especially with the rapid development of the solar energy industry, efficient drying of silicon wafers is one of the important processes in the preparation process of silicon wafers for solar cells. The liners of the existing drying tanks used for drying silicon wafers in the industry are all made of metal and sprayed. The manufacturing cost is high, and it is not easy to process and install. The internal working environment of the tank is relatively complicated. Most of them work in acid, alkali, high temperature and humid environments, and are prone to rust during long-term use, greatly reducing their service life and resulting in unstable working conditions. [0003] In addition, the hot circulating air in the ...

Problems solved by technology

The liners of the existing drying tanks used for drying silicon wafers in the industry are all made of metal and sprayed. The manufacturing cost is high, and it is not easy to process and install. The internal working environment of the tank is relatively complicated. Most of them work in acid, alkali, high temperature and humid environments, and are prone to rust during long-term use, greatly reducing their service life, resulting in unstable working conditions

[0003] In addition, the hot circulating air in the tank of the existing drying tank cannot be evenly distributed inside the tank, resulting in low drying efficiency; moreover, the old heating unit is installed in the tank, and the heating rod itself is expensive, and it is not heated in the tank. Uniformity is easy to cause damage, and the hot air blown out is unevenly distributed, resulting in poor subsequent processes, etc., and the cost of later maintenance and replacement is high, and it is not easy to disassemble and replace
