Problems solved by technology

[0004] However, the above-mentioned anti-overflow monitoring device has poor versatility. For example, some chemical liquids are flammable and poisonous dangerous goods, and the nozzles of the containers to be filled are relatively small. It may be difficult to ensure that the chemical liquid will not overflow through the above color changes, and there is also a lack of relevant explosion-proof and flame-proof measures, so the safety is not high

Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] An anti-spill device for filling, such as figure 1 As shown, it is electrically connected with the filling assembly 1 , and includes a nitrogen gas supply device 2 and an overflow detection module 3 communicated with the nitrogen gas supply device 2 . The nitrogen supply device 2 includes a nitrogen generator 21 , a high-pressure ventilation pipeline 22 and a low-pressure ventilation pipeline 23 .

[0055] Such as figure 2As shown, the high-pressure ventilation pipeline 22 includes a first intake pipe 221, a first control valve 222, a first pressure regulating valve 223, a first butterfly valve 224, and a first outlet pipe 225 connected in sequence; the low-pressure ventilation pipeline 23 includes a sequentially connected The second air intake pipe 231 , the second control valve 232 , the second pressure regulating valve 233 , the second bu...

Abstract

The invention relates to the field of filling technology, and discloses an overflow prevention device for filling, which is electrically connected to a filling assembly, includes a nitrogen supply device and an overflow detection module communicated with the nitrogen supply device, and communicates to the container to be filled. High-pressure nitrogen can quickly fill the container with nitrogen, remove oxygen, and reduce the possibility of explosion of flammable and explosive chemical liquids during the filling process. , the air pressure in the tube remains unchanged. Once the gas outlet end of the inflatable tube comes into contact with the liquid surface, it will hinder the nitrogen gas, thereby increasing the air pressure in the market tube, triggering the air pressure detection module to send an alarm signal, and driving the filling component to stop filling, which is highly safe. , strong versatility.

Description

technical field [0001] The invention relates to the technical field of filling, more specifically, it relates to an anti-overfilling device and method for filling. Background technique [0002] In the manufacturing process of liquid chemicals in the chemical industry, the filling production line will be used in the final stage, and the conveyor belt will be used to transport the container to be filled on the production line. When passing through the filling machine installed on the production line, the filling machine will The filling head extends into the container to be filled to infuse the chemical liquid. [0003] Because the container to be filled has a certain volume, it is necessary to grasp the filling process to prevent the chemical liquid from overflowing. Most of the existing filling anti-overflow devices realize the anti-overflow by comparing the color difference between the chemical liquid and the container to be filled, that is, by monitoring The color change ...
