Abstract
Herein is a coupler and a clean connection device having the same, which can automate a series of operations for connecting and disconnecting a male coupler to and from a female coupler, clean and dry a wetted portion, drain residual liquid of chemicals together with cleaning water without external leakage in safety when the coupler is separated, and clean and dry the wetted surface before connection and after separation, thereby enabling a clean connection.
Claims9
A coupler mounted in a clean connection device including a clean female coupler and a male coupler to load and unload chemicals from one tank to another tank, comprising:
- the male coupler including a male check plunger for opening and closing a flow path in the male coupler while sliding in a male coupler body;
- the clean female coupler including a female check plunger for opening and closing a flow path in the clean female coupler while sliding in a clean female coupler body;
- a coupler cleaning module for cleaning and drying wetted surfaces of the male coupler and the clean female coupler;
- a first O-ring for preventing chemical liquid remaining on the wetted surfaces of the male coupler and the clean female coupler from leaking to outside in a state in which the male coupler is inserted into the clean female coupler body, wherein the flow paths of the male coupler and the clean female coupler are closed;
- and
- a circular ring-shaped reinforcing plate disposed on a cross section of the clean female coupler body facing the male coupler;
- wherein the coupler cleaning module injects a cleaning fluid or a drying fluid into an inner space of the clean female coupler body in a state in which the male coupler is inserted into the clean female coupler body and before the male check plunger and the female check plunger come into contact with each other,
- wherein a fastening hole is disposed in the reinforcing plate, and the reinforcing plate is fastened to the clean female coupler body via a bolt,
- wherein a groove is disposed along a circumference between the clean female coupler and the reinforcing plate,
- wherein the first O-ring is inserted into the groove to be mounted between the clean female coupler body and the reinforcing plate,
- wherein the clean female coupler body includes a second O-ring for preventing the chemical liquid from leaking to the outside in a state in which the male coupler is inserted into the clean female coupler body and the flow paths of the male coupler and the clean female coupler are open, and
- wherein, in the coupler cleaning module, a minute gap is disposed between the second O-ring and the male coupler body in a state in which the male coupler is inserted in the clean female coupler and before the male check plunger and the female check plunger come into contact with each other, and the cleaning fluid passes through the minute gap.

- the clean female coupler including a female check plunger for opening and closing a flow path in the clean female coupler while sliding in a clean female coupler body;
- a coupler cleaning module for cleaning and drying wetted surfaces of the male coupler and the clean female coupler;
- and
- wherein the clean female coupler body has a first O-ring disposed on the clean female coupler body to prevent a residual chemical liquid, which is generated while the male coupler and the clean female coupler are separated from each other in a state in which the male coupler is inserted into the clean female coupler body, from leaking to outside,
- an alignment module for moving the male coupler in an X-axis direction to align with the clean female coupler,
- wherein the alignment module comprises:
- a base plate;
- a pinion rotatably connected to the base plate;
- a pinion driving part rotating the pinion;
- a pair of clamp guide rails extending in parallel in the X-axis direction in a state in which the pinion is interposed between the clamp guide rails;
- a clamp slider guided by the clamp guide rails, the clamp slider having a rack coupled to the pinion;
- and
- an alignment clamp coupled to the clamp slider to align the male coupler by moving in the X-axis direction.
