Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a high-cleanliness drying equipment. Background Technology

[0002] In current drying tank designs used for products such as photovoltaic silicon wafers, the cleanliness level inside the tank decreases after a period of use, leading to product contamination later on. Existing conventional methods involve regular cleaning and maintenance to reduce contamination, but the effectiveness is limited and the cleanliness level cannot be maintained for long. Furthermore, regular cleaning of pipelines is not only labor-intensive but also impacts production line efficiency. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome existing defects and provide a high-cleanliness drying device, including a tank and a heating chamber; an air outlet pipe is provided in the tank, and the air inlet end of the air outlet pipe is connected to the air outlet of the heating chamber; it also includes a return air pipe and a collecting air pipe that are interconnected, the air inlet end of the return air pipe is connected to the tank, and the air outlet end of the collecting air pipe is connected to the air inlet of the heating chamber; a fan is provided in the collecting air pipe to draw air from the tank into the return air pipe and introduce it into the heating chamber for heating, and then circulate it back into the tank through the air outlet pipe;

[0004] It also includes filtering branches;

[0005] The filtration branch includes a high-efficiency filter unit and an air inlet pipe. The air inlet end of the air inlet pipe is connected to the high-efficiency filter unit, and the air outlet end of the air inlet pipe is connected to the air collection pipe. A valve is installed on the air inlet pipe.

[0006] The air outlet pipes are arranged horizontally side by side at the bottom and sides of the trough, forming a 270° air outlet design, which effectively improves the uniformity of airflow within the trough.

[0007] Wherein: the return air ducts are symmetrically arranged and connected to both sides of the trough and both connected to the air collection duct, and the air inlet of the return air duct is located on the lower side of the air outlet duct on the same side and on the outer side of the bottom air outlet duct, respectively, in order to cooperate with the distribution design of the air outlet duct to achieve more effective airflow circulation.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By adding a new filtration branch with a high-efficiency filter unit to the main air circulation pipeline, after the equipment is initially installed, the valve of the air inlet pipe is opened. Under the action of the fan, the outside air is filtered by the high-efficiency filter unit and then enters the tank through the air inlet pipe. After the gas in the tank stabilizes, the valve is closed, so that the gas is heated by the heating box and then begins to circulate inside the tank. This not only ensures the drying effect but also improves the cleanliness of the air, thereby reducing product contamination and improving the working efficiency of the drying tank.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Example 1:

[0015] Please see Figure 1 The high-cleanliness drying equipment provided in this embodiment 1 includes a tank 10 and a heating box 20; an air outlet pipe 31 is provided in the tank 10 and the air inlet end of the air outlet pipe 31 is connected to the air outlet of the heating box 20; it also includes a return air pipe 32 and a collecting air pipe 33 that are connected to each other, the air inlet end of the return air pipe 32 is connected to the tank 10, and the air outlet end of the collecting air pipe 33 is connected to the air inlet of the heating box 20; a fan is provided in the collecting air pipe 33 to draw the air in the tank 10 into the return air pipe 32 and introduce it into the heating box 20 for heating, and then circulate it back into the tank 10 through the air outlet pipe 31;

[0016] It also includes a filter branch; the filter branch includes a high-efficiency filter unit 50 and an air inlet pipe 41. The air inlet end of the air inlet pipe 41 is connected to the high-efficiency filter unit 50, and the air outlet end of the air inlet pipe 41 is connected to the air collection pipe 33.
