Description

Technical Field

[0001] The present invention relates to a calibration device for a metering tank, specifically a calibration device for an industrial metering tank, and belongs to the technical field of metering tank calibration. Background Art

[0002] A metering tank is a device used for material storage in occasions where the metering accuracy requirement is not high. The metering tank is divided into two categories: liquid metering and powder and granular solid metering according to the metering medium. Detection instruments such as liquid level gauges, ultrasonic detectors, and pressure gauges are used to measure the height difference of the material in the container, calculate the material storage volume, and according to the production process and technical requirements, obtain the material height difference signal obtained by the detection instrument, and automatically control the material inlet and outlet actuating components through signal amplification to effectively meter and control the material. Its characteristics are simple structure, convenient operation, and can achieve automatic control. It is suitable for use in occasions where the material storage and metering accuracy requirements are not high. After the industrial metering tank is produced, it needs to be calibrated.

[0003] Chinese Patent No. CN114593807A provides a calibration device for an industrial metering tank, including a heavy object block. A universal wheel is installed at the lower end of the heavy object block. A vacuum piston groove is opened downward at the upper end of the heavy object block. A piston is slidably connected in the vacuum piston groove. The upper end of the piston is connected to a servo electric cylinder. The telescopic shaft of the servo electric cylinder is connected to the piston. A weighing sensor is arranged at the upper end of the servo electric cylinder. A connecting buckle is arranged at the upper end of the weighing sensor. The servo electric cylinder is connected with a power cord, and the power cord supplies power to the servo electric cylinder and the weighing sensor. When calibrating the metering tank of the present invention, the weight is automatically loaded by the action of vacuum suction, without the need for manual loading and unloading of weights, which saves time and effort and reduces labor costs.

[0004] However, although the above case automatically loads the weight by the action of vacuum suction, without the need for manual loading and unloading of weights, which saves time and effort and reduces labor costs, it only has a weighing sensor for weighing, and there is no pressing component and air extraction component to respectively punch the metering tank and measure the negative pressure, which is prone to errors and results in relatively inaccurate calibration of the industrial metering tank.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

The pressure applied to the metering tank is monitored by the air pressure sensor 2 503. The data monitored by the air pressure sensor 2 503 and the pressure sensor 504 are transmitted to the controller 701 for processing. The combination of the air pressure sensor 2 503 and the pressure sensor 504 is adopted to improve the calibration accuracy of the metering tank. The pressure application assembly 300 and the air extraction assembly 500 are adopted to respectively punch the metering tank and measure the negative pressure, improve the calibration accuracy of the industrial metering tank, and avoid calibration errors.
