Kaolin calcining furnace with circuit break warning device

Abstract

The invention discloses a kaolin calcining furnace with a circuit break warning device. The kaolin calcining furnace comprises a furnace body, temperature sensors, heating electric diaphragm plates, motors, an electric control box, a rotating shaft and pushing scrapers, and further comprises an illuminating lamp and a constant current driving power supply, wherein an electric input end of the electric control box is connected on a mains supply circuit; the circuit break warning device is connected on the mains supply circuit; and the circuit break warning device comprises voltage reduction rectifier filer modules and a warner. According to the kaolin calcining furnace, each heating electric diaphragm plate is formed through butt joint of two parts, and the two parts respectively penetrate through electric diaphragm plate mounting holes in the two sides of the furnace body and enter interlayers of hearths, so that maintenance and changing of the heating electric diaphragm plates are greatly facilitated; the remote monitoring manner is adopted, so that the device can be monitored while workers are not beside the device; and the circuit break warning device adopts the technical scheme, so that the circuit structure is greatly simplified, cost is reduced, and the warning effect is quite good.

Description

technical field [0001] The invention relates to a calciner, in particular to a kaolin calciner. Background technique [0002] The biggest defect of the existing kaolin calciner is that it is inconvenient to maintain, especially after the heating parts of each hearth are burnt out, the replacement is time-consuming and laborious, which brings great inconvenience to daily maintenance. [0003] In addition, the temperature of the material discharged from the kaolin calciner is relatively high, and generally it can only be bagged after natural cooling, so the efficiency is low. [0004] The existing kaolin calcining furnaces start calcining without cleaning the poor-quality kaolin, so the produced products are of poor quality. [0005] In the existing kaolin calciner, the staff must stay beside the equipment, which brings great inconvenience to the daily work of the staff. [0006] When the kaolin calciner works at night, it needs lighting. In order to save electricity, LED li...

[0004] The existing kaolin calcining furnace starts calcining without cleaning the poor quality kaolin, so the products produced are of poor quality

[0005] In the existing kaolin calciner, the staff must stay beside the equipment, which brings great inconvenience to the daily work of the staff

[0006] When the kaolin calciner works at night, it needs lighting. In order to save electricity, LED lights are generally used. At present, the power factor correction (PFC) of the driving power used for LED lights is generally realized by an independent transformer. The constant current is realized by using a single 431 or two 431 or stable diodes; therefore, the PFC correction circuit used in the traditional drive power supply is more complicated, the number of components is relatively large, and the cost is high; and the output constant current accuracy is not high, generally within 3 %-10%, has a lot of negative effects on LED lamp beads, shortening the service life of LED
