Kaolin calciner with wire break alarm device

Abstract

The invention discloses a kaolin calcining furnace with a disconnection alarm device, which includes a furnace body, a temperature sensor, a heating electric film plate, a motor, an electric control box, a rotating shaft and a pushing scraper, and also includes an illuminating lamp and a constant current Drive power supply; the electric input terminal of the electric control box is connected to the mains circuit, and the disconnection alarm device is connected to the commercial circuit, and the disconnection alarm device includes a step-down rectification filter module and an alarm. Since the heating electric film plate is formed by butting two halves, the two halves respectively pass through the electric film plate installation ports on both sides of the furnace body and enter the interlayer of the hearth, which greatly facilitates the maintenance and replacement of the heating electric film plate . Due to the remote monitoring method, the staff can monitor the equipment without being near the equipment; because the disconnection alarm device adopts the above-mentioned technical scheme, the circuit structure is greatly simplified, thereby reducing the cost, and the alarm effect is very 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
