Problems solved by technology

However, the spiral partition is set near the kiln tail, which does not make full use of the location advantage of the additional section of the feed inlet to give full play to the pushing effect of the spiral partition, so that the rotary kiln can increase the feed capacity.
[0003] At the same time, in the existing internal heating type rotary kiln, the temperature of the outer wall of the kiln is high, and the temperature at the kiln mouth changes greatly, while the refractory material used here has poor heat resistance and shock resistance, and is easy to fall off, thus affecting the normal production

Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] All electrical components used in the present invention are commercially available.

[0034] The materials mentioned in the embodiments of the present invention are materials that tend to be in a molten state when the temperature is higher than 1000° C., such as phosphate, magnesium oxide and other materials.

[0035] figure 2 It is a longitudinal sectional view of the rotary kiln cylinder. It can be seen from this figure that according to the different shapes of the protrusions set on the inner wall of the cylinder 1, from the feed inlet 11 to the discharge outlet 12, the cylinder inner wall is artificially divided into pusher section 14, The material copy section 15 and the discharge ...

Abstract

The invention discloses a rotary kiln and a production system thereof. The rotary kiln comprises a cylinder (1); one end of the cylinder is a feeding port (11), and the other end of the cylinder is a discharge port (12); and the cylinder (1) is sequentially provided with a material pushing section (14), a parching section (15) and a discharge section (17) from the feeding port (11) to the discharge port (12). With the rotary kiln and the production system thereof provided by the invention, filler content can be increased and material returning can be prevented, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of rotary kilns, in particular to a rotary kiln with a spiral pusher plate and a production system thereof. Background technique [0002] A Chinese utility model patent application with the application number CN200920302713 involves a rotary kiln, figure 1 It is a longitudinal section view of the utility model rotary kiln shell, as figure 1 As shown, a spiral partition 2' is set near the kiln tail on the inner wall of the cylinder 1', and the middle part of the partition is hollow. The purpose of setting spiral partitions is to increase the amount of feed. At the same time, in addition to the area where spiral partitions are set on the inner wall of the rotary kiln, other areas are also provided with partitions 3' extending to the center of the cylinder to achieve production. The purpose of stirring the material from time to time to increase heat transfer. However, the spiral partition is set near the kiln tail, an...
