Problems solved by technology

The disadvantages of weighing and quantification are: first, due to the limitation of the accuracy of ordinary weighing devices, the error of direct weighing is large; and high-precision weighing devices are not suitable for liquids in workshops in terms of cost and operation convenience. Electronic Chemical Filling System
The existing liquid chemical filling system with conveying system is difficult to meet the purity requirements of liquid electronic chemicals
However, designing the entire filling workshop as a high-purity environment, such as a 100-level purification workshop, is costly and consumes a lot of energy

Abstract

The invention discloses a liquid electronic chemical quantitative filling machine. The machine comprises a purifying cabinet, a transmission mechanism, a filling mechanism, and a tank. The cleaning grade of the purifying cabinet is 100 grades or more, and an inlet and an outlet are respectively arranged in the two sides of the purifying cabinet. The transmission mechanism comprises a conveying belt which is used to deliver a package barrel in / out the purifying cabinet. The conveying belt enters the purifying cabinet from the inlet, goes out of the purifying cabinet from the outlet, and extends out the purifying cabinet from the two ends. The filling mechanism is arranged in the purifying cabinet, and comprises at least one filling gun which is communicated with the tank. The filling gun is provided with a delay switch which is used to control the filling time, and the liquid outlet of the filling gun is downward and points to the conveying belt. The tank is provided with a non-touch type liquid level monitor and control device, which is electrically connected to a first electromagnetic valve. The liquid inlet pipeline of the tank is provided with a first pneumatic diaphragm adjusting valve, and the first electromagnetic valve is arranged on the gas source channel of the first pneumatic diaphragm adjusting valve.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a quantitative filling machine for liquid electronic chemicals. Background technique [0002] Liquid chemical quantitative filling machine is a kind of equipment for automatic metering and automatic filling of liquid chemicals. Quantitative filling has certain requirements on the quality error of filling. Taking the national standard as an example, the allowable weight error of liquid electronic chemicals with a capacity of 4L is about 2%, which is about 80g. [0003] The common liquid chemical quantitative filling system is quantitative by weighing. Specifically, use the delivery pump to fill the liquid chemical from the liquid chemical storage tank into the packaging barrel for sale. The packaging barrel is placed on the weighing device. When the specified weight gain is reached, the valve is closed and the filling is stopped. figure 1 shown. The disadvantages of weighing a...
