A kind of device of accurate measurement pitch flow
Technical field
The utility model relates to a kind of device that is used for the accurate measurement of pitch flow, is mainly used in the occasion to the accurate measurement of pitch flow.
Background technology
Existing asphalt flow meter amount instrument has volumeter, vortex shedding flow meter, electromagnetic flowmeter, ultrasonic flow meter and mass flowmeter etc., yet because characteristics such as the high viscosity of pitch itself, temperature sensitivity cause problems such as unstable in the above-mentioned flowmeter course of work, that metering is inaccurate.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of tower structure device is provided, and has solved the inaccurate problem of pitch metering.
The purpose of this utility model is finished by following technical solution, a kind of device of accurate measurement pitch flow, and it comprises: a pitch tank body includes the pitch import and export at the top that is arranged at the pitch tank body; Be arranged at the manhole at the top of pitch tank body; Be arranged at the Floating Ball Liquid Level Control device at the top of pitch tank body; Described pitch import and export and Floating Ball Liquid Level Control device are positioned at the both sides of manhole; Be arranged at the thermometer in the pitch tank body bottom; Be arranged at the conduction oil coil pipe in the bottom of pitch tank body; Be coated on the heat-preservation cotton thermofin of asphalt tank external body; One weighing and sensing apparatus is arranged at the bottom of pitch tank body.
Described LOAD CELLS has three, is evenly distributed on the bottom of pitch tank body, can carry out accurate weighing to the weight of pitch tank body.
Described weighing and sensing apparatus also includes a weight display controller, the pitch in the jar is shown and controls by this device.
The utility model adopts a kind of tower structure device, makes the pitch import and export, manhole, Floating Ball Liquid Level Control, temperature shows, the conduction oil coil pipe, heat-preservation cotton thermofin integrated setting, conveniently moving has improved the problem that in the past can not carry out accurate measurement to the pitch flow.
