Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a flow rate continuous delivery metering device. Background Art

[0002] The silicone automatic line catalyst basically uses tin catalyst, and the addition amount is about 0.03%, and there will be an adjustment of 0.5% in winter and summer. The addition amount of a 1-ton per hour acid transparent production line is 250 grams in summer and 300 to 350 grams in winter (there will be differences between the north and the south). Such a small flow metering pump and flowmeter have too high requirements on the installation site environment and high equipment costs.

The selection of metering pumps and flowmeters and the on-site environment will not be greatly affected. However, if the compounded liquid is not stirred sufficiently, it may cause the liquid to stratify, thus affecting the quality of the product. Utility Model Content

[0030] Working principle: When used for a flow continuous conveyor device, first, the stirring tank 1 is fixed to the fixed ring 401, and the support frame 402 is reinforced with the support beam 403, so as to increase the stability of the stirring tank 1 and prevent shaking during stirring.
