Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic sample delivery systems for online laboratories in the metallurgical industry, in particular to a receiving bowl device for a pneumatic sample delivery machine. Background Art

[0002] The steelmaking laboratory of Anshan Iron and Steel Quality Inspection and Metrology Center is responsible for taking samples in front of the steelmaking furnace and placing the samples in the sample box. The compressed air is sent to the receiving cabinet of the laboratory through the pipeline through the pneumatic sample delivery cabinet installed in front of the furnace. The robot takes out the samples and distributes them to various instruments in the laboratory for testing the sample composition. The test results are then sent to the production plant through the network.

[0003] Since there are 36 sets of pneumatic sample delivery cabinets installed in front of the furnace machine on site, whether the pneumatic sample delivery system can send sample boxes normally is a key link to ensure the stable and smooth operation of the steel plant. Since the pneumatic sample delivery device sends sample boxes back and forth very frequently, each set of sending and receiving cabinet sends and receives sample boxes about 100 times a day on average. The receiving bowl of the sending and receiving cabinet is frequently impacted by the sample boxes. Basically, the inner buckle bolts connecting the bowl and the flange will loosen in about two days, and even cause the bolts to break in the bowl. Maintenance is time-consuming and laborious, and some cannot even be repaired. The bowl is connected to the cylinder rod, and long-term impact causes shaking, causing the connecting thread head between the cylinder and the flange to break in the cylinder, causing the cylinder to be scrapped. Therefore, we proposed a device for receiving the bowl of the pneumatic sample delivery machine to solve the above problems. Utility Model Content
