Problems solved by technology

However, using the above method to clear the kiln circle will lead to relatively large economic losses. On the one hand, the reduction or stoppage of production is caused by the reduction or stoppage of materials, while the consumption of fuel and electricity is not reduced, and the wear and tear of equipment is not reduced; on the other hand, because of the significant The alternating action of cold and heat will cause partial cracking of the kiln lining and the peeling of the kiln skin, which will damage the kiln lining and even cause deterioration of calcination.

Embodiment Construction

[0011] In the embodiment shown in Figure 1, a group of rails (8) are set near the kiln tail (4) of the rotary kiln, and a trolley (7) is arranged on the rail (8), and a stretchable Entering the cleaning arm (5) of the kiln ring forming area (2) of the rotary kiln, the front end of the cleaning arm (5) is provided with a scraper (3). Open an opening at the kiln tail (4) of the rotary kiln, extend the cleaning arm (5) and the scraper (3) into the kiln circle forming area (2) in the rotary kiln, and use the Kinetic energy and relative displacement, to automatically clear kiln circles or prevent kiln circles from forming.

[0012] In another embodiment shown in Fig. 2, near the kiln tail (4) of the rotary kiln, a group of tracks (8) are set, and a trolley (7) is provided on the track (8), and a trolley (7) is provided with a The cleaning arm (5) that can extend into the kiln ring forming area (2) of the rotary kiln, the front end of the cleaning arm (5) is provided with a scraper...

Abstract

A method and device relate to elimination of attachments in a rotary kiln. The device consists of a set of rails, a pulley on them, an arm with a scraper on its front end, which is installed on the pulley to extend into the kiln, and cooling medium channels installed in the arm and scraper. Attachments are automatically removed when the rotary kiln rotates and shifts oppositely.

Description

Technical field [0001] The invention relates to a method for removing the kiln circle of a rotary kiln, in particular to a method and a device for removing the kiln circle of the rotary kiln or preventing the formation of the kiln circle. Background technique [0002] At present, the known method of clearing the kiln ring of the rotary kiln is: when the kiln ring is formed, reduce feeding or stop feeding, move the nozzle of the burner forward for several hours, increase the temperature of the kiln ring, and then move the nozzle of the burner backward for several hours to reduce The temperature of the kiln circle, repeatedly moving the nozzle of the burner several times, makes the kiln circle crack and collapse under the obvious alternating action of cold and heat. However, using the above method to clear the kiln circle will lead to relatively large economic losses. On the one hand, the reduction or stoppage of production is caused by the reduction or stoppage of materials, ...
