A steel drum filling device that automatically discharges static electricity and a safe filling method

Abstract

A steel drum filling device and a safe filling method for automatically releasing static electricity. The invention provides an automatic filling device and a filling method that can guide and remove static electricity that chemical materials carry when filling steel drums or that are generated by friction with steel drums during the filling process, and prevent static sparks from being generated. , and at the same time send the obtained signal to the automatic control system for data comparison for safety control. The device includes a charging structure, a weighing system and a grounding structure; wherein, the grounding structure includes a cylinder, a contact and a fixing frame, and there are two contacts, which are respectively contact I and contact II. According to the characteristics of the filling container, this new electrostatic discharge filling device does not use the thimble to break the paint, but uses the copper sheet contact to softly connect with the small cover of the filling container vent hole, completely avoiding the defect of the traditional grounding clip impact. In particular, this device is an automatic electrostatic discharge device that combines machinery, pneumatics and electricity. It has a high degree of automation and a large safety factor. It can effectively protect the health of operators, reduce labor intensity, and greatly improve production efficiency.

Description

technical field [0001] The invention relates to a steel barrel filling device with the function of automatically releasing static electricity and a safe filling method, and is especially suitable for filling inflammable and explosive materials in the chemical industry. Background technique [0002] At present, most of the devices used to discharge static electricity are grounding clips, which are firmly clamped on the object by a strong spring, and penetrate the insulating layer such as the surface paint of the object through a sharp thimble, so that the object can be connected to the ground to eliminate static electricity. The electrostatic discharge devices that can be found on the market can be divided into the following types: 1. "O" type electrostatic grounding clamp suitable for clamping on tubular objects; 2. "C" type electrostatic grounding clamp suitable for clamping on a more raised position 3. A "double-probe" electrostatic grounding clip suitable for clipping in ...

AI Technical Summary

Problems solved by technology

When the thimble of the traditional grounding clamp is connected to the steel drum, it will collide and even generate sparks, which is very dangerous for the filling of chemical raw materials with explosion-proof requirements.
