Kaolin calciner with control cable

Abstract

The invention discloses a kaolin calcining furnace with a control cable. The kaolin calcining furnace comprises a furnace body, a temperature sensor, a heating electric film plate, a motor, an electric control box, a rotating shaft and a pushing and scraping plate, a lighting lamp which is an LED lamp, a constant-current driving power supply and a control cable connected with the electric control box, wherein the control cable comprises four cable cores; each cable core group is composed of two cable core conductors with insulation layers; a glass silk filling rope is arranged between the four cable core groups; a glass fiber coating tape is arranged at the periphery of the four cable core groups; a metal shielding layer is arranged at the periphery of the glass fiber coating tape; an outer sheath made of a flame-retardant polyether type thermoplastic polyurethane elastic material is arranged at the periphery of the metal shielding layer; a polyester film coating tape is arranged between the metal shielding layer and the outer sheath. The cable adopts the outer sheath made of the flame-retardant polyether type thermoplastic polyurethane elastic material, so that the cable can operate in the high-temperature or low-temperature environment; the cable is not easy to crack; the low-temperature impact capability is improved.

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 calcining furnace is that it is inconvenient to maintain, especially after the heating parts of each hearth burn out, it takes time and effort to replace, which brings great inconvenience to daily maintenance. [0003] In addition, the temperature of the material discharged from the kaolin calciner is relatively high, and it is generally not bagged until it is naturally cooled, so the efficiency is low. [0004] The existing kaolin calcining furnace starts to calcinate the poor quality kaolin without cleaning, so the quality of the products produced is poor. [0005] In the existing kaolin calcining furnace, the staff must be guarded by the equipment, which brings great inconvenience to the staff's daily work.

AI Technical Summary

Problems solved by technology

[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 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

[0007] The control cables used in traditional kaolin calciner are easy to crack in high temperature environment or low temperature environment, and the low temperature impact resistance is poor, so its service life is short
