Description

  The present invention relates to a strainer device suitable for use in a facility that uses a shipping device to load liquid into a tank truck.

  For example, the oil liquid is delivered to an oil storage such as a gas station using a tank truck. A tank of a tank truck is usually divided into a plurality of hatches (loading tanks). For delivery, the tank truck is loaded with the order quantity of the liquid oil corresponding to the order of the delivery destination for each hatch at the shipping stage of the oil tank station.

  At the oil tank station shipment stage, when a tank truck arrives, the vehicle number card for connecting the tank truck to the grounding device and identifying the tank truck is used to start loading the oil into each hatch using the shipping device. Is read by the operator.

  Of these, by reading the car number card, the shipping control device at the shipping stage sends a tank setting car to the tanker truck with the car code with the hatch setting device based on the reservation data according to the order from the delivery destination in advance. Loading data including the loading liquid type and loading quantity for each hatch at the time of delivery is allocated. The shipping control device controls the shipping device provided at the shipping stage based on the loading data, and causes the shipping device to load the oil into each hatch of the tank truck with the vehicle number code.

  Using the shipping device, the worker uses the shipping device based on the delivery slip that is also created by the host computer based on the reservation data and instructed the loading liquid type and loading quantity of each hatch for each delivery of the tank truck. Load oil into each hatch at the time of delivery.

  In the loading operation, the operator selects and operates the loading arm of the liquid type to be loaded into the hatch from the plurality of loading arms provided for each liquid type of the shipping device, and drops the drop pipe at the end of the arm. Is inserted into the hatch through the hatch inlet.

  At that time, for example, the operator operates the loading setting device to set the type and quantity of liquid to be loaded, and the hatch card provided in the hatch injection port with a chain or the like is provided on the loading arm. The shipment control apparatus is made to acquire work information such as the type and quantity of the oil liquid to be actually supplied, hatch identification, etc. by causing the card reader to read it.

  The shipping control device checks this work information against the loading data, and if there is an error in the type / quantity of the liquid oil to be loaded and the hatch, it notifies the operator of the fact and controls the shipping device. Therefore, the loading operation using the shipping device is managed without error so that the oil liquid is not loaded.

  By the way, in the shipping device, the liquid supply system part including the loading arm actually circulates inside, so the purpose is to find corroded parts that cause oil leakage and to remove the attached sludge. Inspected regularly.

  In this periodic inspection, for example, a loading arm will be described as an example. After being removed from the shipping device and disassembled into each pipe part including a drop pipe, the oil is used, for example, as a seal member of a joint part. The exposed member is replaced as necessary from the viewpoint of performance, while sludge or the like adhering to the inner surface of the pipe is removed by cleaning with a waste cloth. And after inspection, it is assembled | attached to a shipping apparatus as a loading arm.

  However, after the above-described periodic inspection of the shipping device, for example, sludge that could not be removed during cleaning or small pieces of waste that were cut off during cleaning were overlooked and left as foreign matter in the liquid feeding system. In such a case, when the oil liquid is loaded immediately after the inspection, these foreign substances may be discharged together with the oil liquid from the loading arm into the hatch of the tank truck.

  However, the inside of the hatch of a tank truck can only be seen through the hatch injection port for inserting the drop pipe at the tip of the loading arm formed on the ceiling hatch wall. Since a drop pipe is inserted into the mouth and oil liquid is discharged in the hatch by the drop pipe, it is difficult to confirm whether or not foreign matter has been left behind during the inspection as described above.

  Further, even if it is confirmed that foreign matter left behind at the time of inspection is generated and discharged into the hatch, it is extremely difficult to remove it from the hatch because of its structure.

  The present invention has been made in view of the above-described problems, and even if a foreign object is overlooked and left behind during a periodic inspection of a liquid feeding system part including a loading arm of a shipping device. Provided is a strainer device for a shipping device that prevents foreign matter from being discharged from the loading arm into the hatch of the tank truck with the loaded liquid when the liquid is loaded into the tank truck using the shipping device immediately after inspection. For the purpose.

  In order to solve the above-described problem, the present invention inserts a drop pipe of a loading arm provided in a shipping device from a liquid injection port of the hatch when loading liquid into a hatch of a tank truck using the shipping device. Prior to the above, a strainer device for a shipping device disposed in the liquid inlet, an insertion tube into which the distal end is inserted into the hatch from the liquid inlet and the drop pipe is inserted from the proximal end, and an insertion A tip cover that is provided at the tip of the insertion tube so as to cover the tip of the drop pipe inserted into the tube and has a plurality of communication holes communicating with the inside and outside of the wall, and is disposed in the tip cover. A strainer that is attached to the distal end of the insertion tube integrally with the distal end cover, covers the distal end portion of the drop pipe together with the distal end cover, and is formed to protrude from the proximal end portion of the insertion tube. Than to engage the parts, characterized in that it includes a regulating portion for regulating an insertion depth of the distal end cover in the hatch.

  According to the strainer device for shipping apparatus of the present invention, when foreign matter exists in the liquid discharged from the drop pipe of the loading arm, the foreign matter is captured by the strainer device for shipping apparatus arranged in the liquid injection port. Therefore, foreign matter is prevented from being discharged into the hatch.

  Furthermore, since the strainer arranged in the tip cover provided at the tip of the insertion tube can be attached and detached integrally with the tip cover, for example, depending on the type of liquid to be loaded and the size of foreign matter And can be easily changed to a strainer with a different mesh.

Further, since the restriction cover holds the tip cover at the insertion depth position where the tip cover itself does not contact the bottom surface of the hatch and the strainer does not contact the tip of the drop pipe, the tip of the loading arm contacts. Thus, it is possible to prevent the strainer and the bottom surface of the hatch from being damaged.
