The conventional method of delivering chemicals from the above-described tank truck to the chemical storage tank uses a method in which an operator manually connects a hose and a joint for supplying chemicals, which will be described in detail below.
The tank car is connected with a chemical supply hose and a nitrogen supply hose, the end parts of the chemical supply hose and the nitrogen supply hose are respectively connected with a Male joint (Male Connector) for chemicals and a Male joint for nitrogen, and the Male joints are respectively provided with a closed end part of a cover (Cap).
The chemical tank is provided with a chemical Female Connector (Female Connector) and a nitrogen Female Connector, and a chemical male Connector and a nitrogen male Connector are inserted into the chemical Female Connector and the nitrogen Female Connector, respectively. The chemical female connector and the nitrogen female connector are also provided with caps (Cap) respectively for closing the ends.
The operator pulls out the chemical hose and the nitrogen hose from the tank car, and separates the chemical male joint cover and the nitrogen male joint cover from the chemical female joint cover and the nitrogen female joint cover. Thereafter, the chemical male connector is connected to the chemical female connector, and the nitrogen male connector is connected to the nitrogen female connector.
As described above, in a state where the male connector and the female connector are connected, nitrogen gas of a constant pressure is supplied from the nitrogen gas storage tank located in the building to the tank car through the nitrogen gas hose, and the chemical in the tank car is transferred to the chemical storage tank through the chemical hose due to the pressure of the nitrogen gas.
However, according to this conventional method, when an operator manually connects and separates the chemical and nitrogen gas joints and supplies nitrogen gas at a constant pressure, the chemical may leak out, and the operator may be exposed to the chemical.
As a prior art of the chemical supplying apparatus, Korean Utility model laid-open No. 20-2016-.

The fixing pin 154 is formed in a cylindrical shape having a predetermined length, and is inserted into the fixing pin insertion portion 535 of the key code block 530, the fixed key code block 530, the buffer flange 520 coupled thereto, the male tab 510, and the like so as not to move on the resting portion 150 when moving forward together with the moving member 153.
The moving member 153 supports a guide member 155 at a lower portion thereof so as to be movable in the front-rear direction. A pair of fixing pins 154 are integrally coupled to both sides of the front end of the moving member 153.
A handle portion 156 is integrally coupled to one side of the moving member 153. The operator may move the moving member 153 and the fixing pin 154 in the forward and backward directions by pushing or pulling the handle 156 forward or backward.
The locking sensor 158 senses the forward movement of the moving member 153 and the insertion of the fixing pin into the fixing pin insertion part 535, and is provided at a lower portion of the support plate 157.
The supporting plate 157 has a through hole 157a penetrating vertically, and the locking sensor 158 is formed at a lower portion of the through hole 157 a.
A sensing pin 156a having a vertical length is integrally formed at a lower portion of the handle portion 156. The sensing pin 156a surrounds the handle housing 156 b. The handle portion 156 and the handle case 156b are separated from each other, and the handle portion 156 and the handle case 156b are connected to each other by an elastic member (not shown) such as a spring. When the operator pulls the handle portion 156 upward, the elastic member is extended, and the handle portion 156 and the sensing pin 156a move upward, and when the operator releases the handle portion 156, the sensing pin 156a moves downward together with the handle portion 156 due to the resilient force of the extended elastic member.
The lower end of the handle portion 156 and the upper end of the handle case 156b may be formed with a concavity and a convexity formed by a valley and a peak along the circumference of the contact surface. When the peak of the handle portion 156 and the peak of the handle case 156b contact each other, the handle portion 156 and the handle case 156b are isolated from each other. When the above-mentioned peaks/valleys of the handle portion 156 meet the valleys/peaks of the handle case 156b, respectively, the handle portion 156 and the handle case 156b approach each other due to the pulling force of the elastic member. Thus, the operator may rotate the handle portion 156 to cause the peak to peak or peak to valley to meet.
When the fixing pin 154 is moved backward, as shown in fig. 13, the lower end of the sensing pin 156a contacts the upper surface of the supporting plate 157. At this time, the grip portion 156 and the fixing pin 154 are in a state of moving upward relative to the grip case 156b, and the elastic member is in a stretched state.
In the state of fig. 13, when the operator grips the handle portion 156 and pushes it forward, the fixing pin 154 moves forward integrally with the moving member 153 and the sensing pin 156a, and when the fixing pin 154 is inserted into the fixing pin insertion portion 535, the sensing pin 156a is positioned above the through hole 157 a.
In this state, when the operator rotates the handle portion 156, the valley and the peak of the handle portion 156 and the handle case 156b meet each other, the sensing pin 156a and the handle portion 156 are pulled downward by the elastic member, and as shown in fig. 14, the sensing pin 156a moves downward by the elastic member, passes through the through hole 157a, and is positioned above the lock sensor 158.
The locking sensor 158 senses the sensing pin 156a, whereby the operator can know that the chemical hose 500 and the nitrogen hose 600 are fixed to the shelf portion 150 for the next operation. If the lock sensor 158 does not sense the sensing pin 156a, the automatic chemical supplying apparatus 100 is not operated.
The operation of the chemical automatic apparatus 100 of the present invention having the above-described configuration will be described.
The operator rotates and opens the upper door 132 of the shield door 130 upward. At this time, the shelf 150 is located inside the frame 120, adjacent to the shield door 130.
A chemical male joint 510 and a nitrogen male joint are connected to the ends of the chemical hose 500 and the nitrogen hose 600, respectively, and the open distal ends of the chemical male joint 510 and the nitrogen male joint are plugged by a chemical male joint cap (not shown) and a nitrogen male joint cap (not shown), respectively. The operator pulls the chemical hose 500 and the nitrogen hose 600 in this state out of the tank car, removes the above-mentioned male connector cap manually, and then rests on the resting member 151 of the resting portion 150 inside the frame 120, as in the state of fig. 10 and 12. Of course, it may be arranged to automatically remove the male cap by a male cap removing unit (not shown).
As described above, when the chemical hose 500 and the nitrogen hose 600 are rested on the resting member 151 of the resting portion 150 to become the state of fig. 13, the resting sensor 159 senses the normal resting thereof. In this state, the operator grasps the handle portion 156 and pushes forward, the fixing pin 154 is inserted into the fixing pin insertion portion 535, and the chemical hose 500 and the nitrogen hose 600 are fixed to the placement portion 150. If the lock is properly secured, the lock sensor 158 can sense the lock.
At this time, the chemical female joint cap (not shown) covering the end of the chemical female joint 210 and the nitrogen gas female joint cap (not shown) covering the end of the nitrogen gas female joint are automatically removed from the chemical female joint 210 and the nitrogen gas female joint by the female joint cap removing unit (not shown).
In this state, the moving unit 160 is driven, the chemical hose 500 and the nitrogen gas hose 600 linearly move forward, and the chemical male joint 510 and the nitrogen gas male joint are coupled to the chemical female joint 210 and the nitrogen gas female joint, respectively, so that the chemicals can be transferred.
