[0002] Instruments disassembled from the field often contain a large amount of residual oil. Laboratory calibration of pressure instruments requires extremely high cleanliness; any oil leakage can interfere with calibration accuracy and damage the equipment. Traditionally, workers have used manual, individual oil draining or simple support methods, which are inefficient, result in messy oil collection, and risk secondary contamination of lower-level instruments.

Then, the pressure instruments that need to be drained are classified and placed in the independent rectangular grids of different sizes on each layer of the vertical frame. The residual oil in the instrument drips naturally under the action of gravity and the oil gathers in the lower part of the guide structure. (2) The oil can be directionally transported along the lower structure to avoid dripping onto the lower instruments and causing secondary pollution. Finally, the oil transported from each layer falls into the oil collection tank on the bottom shelf of the vertical frame for centralized collection.

[0005] The outlet area of ​​the lower structure is smaller than the area of ​​the guide opening in the middle of the placement rack, and the outlet extends downwards through the guide opening of the next layer. An apparatus for draining oil from pressure gauges comprises: a vertical frame, a flow guiding structure, and an oil collection structure. The vertical frame has at least two layers. A flow guiding structure is fixed below the placement rack of each layer of the vertical frame. Each layer of the placement rack is fixedly connected by four columns. An oil collection structure is provided at the bottom layer of the vertical frame. The flow guiding structure includes an upper structure, the lower end of which is fixed to a lower structure, and the outlet of the lower structure passes through the guide port of the layer below the flow guiding structure and extends below the guide port.

[0010] 1. This invention adopts a multi-layer vertical frame design and divides the rectangular grid into multiple independent rectangular grids of different sizes, which can perform oil draining treatment on multiple pressure gauges of different specifications. Compared with manual individual oil draining, it greatly improves the work efficiency of oil draining and meets the needs of industrial production or laboratory batch calibration.

[0011] 2. In this invention, the lower structure of each layer of the vertical frame's flow guiding structure directly passes through the guide port of the lower placement rack, allowing the oil from each layer of pressure gauges to be directly introduced into the oil collection tank without dripping onto the lower layer gauges. This avoids secondary contamination of the pressure gauges, ensures the cleanliness of the gauges, and guarantees the accuracy of subsequent calibration.

[0015] A method for draining oil from pressure instruments, the method comprising the following steps: (1) Before the laboratory calibration of the pressure instrument, it can be moved flexibly by the casters under the column. After moving to the appropriate position, it will automatically lock. Then, the pressure instruments that need to be drained are classified and placed in the independent rectangular grids of different sizes on each layer of the vertical frame. The residual oil in the instrument drips naturally under the action of gravity and the oil gathers in the lower part of the guide structure. (2) The oil can be directionally transported along the lower structure to avoid dripping onto the lower instruments and causing secondary pollution. Finally, the oil transported from each layer falls into the oil collection tank on the bottom shelf of the vertical frame for centralized collection. After the oil collection tank is full, it is removed for processing and replaced, and the device can continue to drain oil.

[0016] The outlet area of ​​the lower structure is smaller than the area of ​​the guide opening in the middle of the placement rack, and the outlet extends downwards through the guide opening of the next layer. An apparatus for draining oil from pressure gauges comprises: a vertical frame 1, a flow guiding structure 2, and an oil collection structure 13. The vertical frame has at least two layers. A flow guiding structure is fixed below the placement rack 3 of each layer of the vertical frame. Each layer of the placement rack is fixedly connected by four columns 4. An oil collection structure is provided at the bottom of the vertical frame. The flow guiding structure includes an upper structure 6, with a lower structure 7 fixed to the lower end of the upper structure. The outlet 8 of the lower structure passes through the guide port 11 of the layer below the flow guiding structure and extends below the guide port. The flow guiding structure is used to guide the oil to converge towards the center.

[0017] The four uprights are fixed to the four corner edges of each shelf to ensure the stability of the overall structure, and each upright is connected to a caster wheel 5.

[0018] The placement rack includes two rectangular grids 12 and a guide opening. The guide opening is rectangular and is located in the middle part of the placement rack. The two rectangular grids are symmetrically distributed on both sides of the guide opening. Each rectangular grid is divided into multiple independent rectangular small squares of different sizes, and these rectangular small squares are arranged in an alternating pattern of large and small squares for classifying and placing pressure instrument components of different models.

[0019] The upper structure is in the shape of a quadrangular frustum, and the upper opening of the upper structure is larger than the lower opening. The lower opening of the upper structure is fixed to the upper opening of the lower structure. The lower structure is a cuboid channel, and the upper opening of the lower structure has the same area as the lower opening of the upper structure.

[0020] The oil collection structure includes a barrel rack, the four corner edges of which are fixed to the four columns. An oil collection barrel 10 is placed on top of the barrel rack 9, and the oil collection barrel is located below the lowest layer of the vertical frame.

[0021] Working principle: Before laboratory calibration of pressure instruments, the pressure instruments requiring oil draining are categorized and placed in independent rectangular compartments of different sizes on each layer of the vertical frame. Residual oil inside the instruments drips naturally under gravity, first falling onto the guide structure below the placement rack. The oil then collects in the lower part of the guide structure. Because the outlet area of ​​the lower structure is smaller than the area of ​​the guide port in the middle of the placement rack, and the outlet extends downwards through the guide port of the next layer, the oil can be directionally transported along the lower structure, avoiding secondary contamination caused by dripping onto the instruments on the lower layer. Finally, the oil transported from each layer falls into the oil collection tank on the bottom layer of the vertical frame for centralized collection. The casters under the column can move flexibly and automatically lock when moved to the appropriate position. Once the oil collection tank is full, it is removed for processing and replaced, and the device can continue oil draining operations.
