Description

Technical Field

[0001] The invention relates to the technical field of rubber production, in particular to an automatic discharge and recycling device for out-of-tolerance oil on an oil scale. Background Art

[0002] Fuel out-of-tolerance typically refers to metering out-of-tolerance in the refueling equipment. This primarily occurs when the refueling equipment, due to internal or external factors, causes metering errors during the refueling process, resulting in refueling amounts exceeding or falling short of the actual required amount. Currently, conventional internal mixer oil scales lack an out-of-tolerance discharge function. This results in substandard rubber produced after oil out-of-tolerance. Direct use of the product results in substandard final rubber, additional labor intensity, and improper isolation, which can compromise rubber quality and significantly reduce practicality.

A control system can be set on one side of the frame 102 to facilitate input or output of instructions to the electrical components through the control system. An oil outlet 103 is set at the bottom of the scale body 101. The oil outlet 103 and the oil preparation hopper 200 are connected through a discharge pipe 104. The lower end of the discharge pipe 104 is provided with a telescopic component to facilitate adjustment of the distance between the discharge pipe 104 and the oil preparation hopper 200 to avoid flying when there is too much oil. In order to prevent oil from splashing to the outside, an annular block 105 is fixedly provided on the outer wall of the scale body 101, and support rods 106 are symmetrically installed on the upper surface of the annular block 105.

The control valve bodies are all electric valves, which are convenient for automatic control. Flow monitoring meters are installed inside the oil preparation hopper 200, the scale body 101, the oil recovery bin 301 and the oil storage bin 302 to ensure the normal operation of the device and facilitate the transportation of oil to the corresponding components.

[0040] During use, when the oil scale 100 weighs the oil and an out-of-tolerance situation occurs, the oil is discharged to the oil recovery bin 301 through the control valve body and the recovery pipeline 303. After the oil in the oil recovery bin 301 reaches a certain amount, part of the oil is pumped back into the scale body 101 through the corresponding oil outlet pipeline 304 for use by the next truck of rubber. If the formula is completed or the second oil is also displayed as out-of-tolerance, the oil in the oil recovery bin 301 is transported to the corresponding oil storage bin 302 through another oil outlet pipeline 304 for subsequent use. During the oil weighing process, the switch assembly can be adjusted by adjusting the position of the slide plate 409. The weights of the components such as the scale body 101, the discharge pipe 104, the annular block 105, the support rod 106, and the cross bar 107 in the oil scale 100 in this device are all fixed values, which is convenient for adapting to oils of different weights.
