Wireless charging device for rotary kiln and rotary kiln

Abstract

The invention discloses a wireless charging device for a rotary kiln and the rotary kiln. The device comprises a wireless charging receiving module, a charging module, a power receiving module, a rechargeable battery and a wireless charging emission module, wherein the wireless charging receiving module, the charging module, the power receiving module and the rechargeable battery are arranged on an outer surface of a kiln sink of the rotary kiln. When the wireless charging receiving module is rotated to a part within a transmission distance range of the wireless charging emission module with akiln body, the wireless charging receiving module can be used for receiving electromagnetic field energy of the wireless charging emission module, converting an electromagnetic wave to a current andsupplying power to the power receiving module and the rechargeable battery by the charging module; and when the wireless charging receiving device is rotated to a part out of the transmission distancerange of the wireless charging emission module, the wireless charging receiving module is used for stopping energy conversion, and the power receiving module is switched to power supplied to the rechargeable battery. By the device, the rechargeable battery can be charged for a certain time when the kiln body rotates for a circle, the charging quantity of the rechargeable battery is larger than power consumption quantity of the power receiving module, so that normal working of the power receiving module is ensured, and the problem that the battery is frequently replaced is prevented.

Description

technical field [0001] The invention relates to the technical field of a rotary kiln, in particular to a wireless charging device for a rotary kiln and the rotary kiln. Background technique [0002] Rotary kiln is a cylindrical high-temperature kiln placed on an incline and can rotate continuously. As a thermal equipment for drying and roasting materials, it is widely used in non-ferrous smelting, iron and steel metallurgy, chemical industry, cement, alumina, building materials And in the technological process of industries such as refractory materials. [0003] During the operation of the rotary kiln, in order to realize process status monitoring, monitoring devices such as wireless temperature measuring devices and pressure measuring devices are usually installed on the outer surface of the rotary kiln. The above monitoring devices rotate with the rotary kiln body to detect in real time Process parameters such as temperature and pressure in the rotary kiln. Usually, batt...
