Purpose of the utility model is realized as follows: a kind of photoresists automatic filtering unit, including tank body, it is placed in tank body
The end cap at top and the discharge gate for being placed in tank base are additionally provided with feed pipe on end cap, it is characterised in that: the inner wall of the tank body
It is equipped with step groove, step groove is equipped with filter assemblies, and filter assemblies include filter frame and the filtering layer that is placed in filter frame, and filtering layer includes
Fiber filter cloth, metal screen and the porous plate from top to bottom set gradually is additionally provided with forcing pipe at the top of end cap, connects on forcing pipe
It is connected to supercharging air pump, tank body side is additionally provided with the transparent pipe for observing tank substance in vivo height, the both ends difference of transparent pipe
It is connected to the bottom and top of tank body.
The utility model is further arranged to: the periphery wall of the tank body is equipped with heating chamber, and heating chamber is equipped with import
And outlet, the outer wall for reinforcing chamber are equipped with vacuum heat-preserving chamber, vacuum heat-preserving chamber is equipped with bleeding point.
The utility model is further arranged to: the inner edge of the filter frame is equipped with the card slot for lifting.
The utility model is further arranged to: the feed pipe is equipped with the control valve that control is only led to.
The utility model is further arranged to: the pressure gauge for detecting tank interior pressure is additionally provided on the end cap.
Have the advantage that filtering layer is made of multilayered structure by using above-mentioned technical proposal, intensity is good, filter effect is good
And the rate of filtration is fast；
Inert gas can be passed through in filter process by supercharging air pump, improves tank interior pressure, increases filtering rate；
It is more convenient and practical convenient for liquid level in observation tank body by the setting of transparent pipe；
Heating chamber inner casing filling circulation conduction oil or steam play the role of heating and thermal insulation to tank body, more conducively filter.
