Embodiment 1

[0030] A high-temperature powder automatic feeding device (parts such as figure 1 shown), including a feed bin 1 and a feeding system connected from top to bottom; the feeding system includes a feeder 2, and the feeder 2 inlet is directly connected with the feeder 1 outlet;

[0031] The device also includes a temperature control system, a voltage stabilizing system, a weight sensor 12 and an automatic control system 13;

[0032] The temperature control system includes a heater 5 and a temperature transmitter 4 that are respectively connected to the feed bin 1; the heater 5 and the temperature transmitter 4 are also connected to an automatic control system 13 respectively;

[0033] The pressure stabilizing system includes a feed end voltage stabilizing unit connected to the inlet of the silo 1 and a discharge end voltage stabilizing unit connected to the outlet of the feeder 2; in the feed end stabilizing unit, one end of the pressure sensor 6 is connected to the The inlet of ...

Embodiment 2

[0037] A high-temperature powder automatic feeding device (such as figure 1 shown), compared with Example 1, the difference is only that nitrogen is introduced into the working air ducts 8 and 11, the feed pipe connected to the inlet of the feed bin 1 is provided with a flexible connection a, and the feed pipe connected to the feeder 2 outlet The discharge pipe is provided with a soft connection d, the working air channel 8 of the pressure stabilizing unit at the feed end is connected with the inlet of the silo 1, and the working air channel 11 of the pressure stabilizing unit at the discharge end is connected with the outlet of the feeder 2 Set up a soft connection c.

Embodiment 3

[0039] A high-temperature powder automatic feeding device (such as figure 1 shown), compared with Example 2, the difference is only that: the temperature control system monitors the temperature in the silo in real time, the pressure stabilizing system monitors the pressure at the silo inlet and the feeder outlet in real time, and the weight The sensor monitors the weight of the material in the silo in real time, and each component transmits the monitoring signal to the automatic control system in real time;

[0040] At the same time, the automatic control system sets preset values ​​for temperature, pressure, and material flow. After receiving the temperature, pressure, and material weight monitoring signals, it processes the signals and calculates the actual value, and compares the actual value with the preset value. In comparison, if the actual value deviates from the preset value, the automatic control system transmits an adjustment signal to the outside to adjust the tempe...

Abstract

The invention relates to a high-temperature powder material automatic feeding device and an application thereof. The device comprises a bunker and a charging system connected from up to down; and also comprises a temperature control system, a pressure stabilizing system, a weight sensor and an automatic control system. The device realizes accurate metering of gas and solid two-phase fluids, and can realize continuous or interrupt charging as well as charging with stable flow or variable flow; the powder conveying is smooth, blockage is difficulty generated, and the automation degree is high. The invention also provides an application of the device in industrial production.

Description

technical field [0001] The invention relates to a feeding process, in particular to an automatic feeding device for high-temperature powder materials and its application. Background technique [0002] In the existing feeding process, the flow meter is generally used for direct measurement, and the measurement is not accurate under the condition of air flow. Patent document CN103754658A discloses a continuous powder feeding device and a real-time control method; the hopper of the powder continuous feeding device is installed on the weighing platform of the scale on the support; when feeding: by weighing the initial feeding amount, weighing The weight before and after the connection between the feeding device and the mixing pot controls the amount of feeding; by adjusting the opening of the feeding valve and the switch of the vibrator, the speed control of the feeding process is realized. [0003] However, the existing feeding process is inaccurate for gas-solid two-phase flu...
