Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln feeding device. Background Art

[0002] At present, the feeding device of the rotary kiln is usually simple and has a single function of feeding the material, which increases the process and procedures of the preliminary preparation, and the feeding device of the rotary kiln has always been the place where dust pollutants appear.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN207379262U, which discloses a rotary kiln feeding device, including: a bucket elevator, a hopper, a spiral mixer and a dust removal device; the bucket elevator lifts the material and transports it into the hopper, and the hopper cover is placed above the bucket elevator outlet to avoid the generation of floating dust. The material passes through the hopper and then enters the spiral mixer for material mixing, while feeding is achieved. At this time, the inclination angle of the spiral mixer is controlled to assist in controlling the mixing time of the material. The fully mixed material finally enters the rotary kiln, and the dust removal device is always in working condition to absorb floating dust at the hopper position and the rotary kiln entrance position.

[0004] Although the above-mentioned rotary kiln feeding device quickly introduces materials into the bucket elevator entrance through the introduction box to solve the problem that the existing feeding device has no corresponding dust removal measures, the above-mentioned equipment is not convenient for removing dust only through the rotary kiln dust cover and the hopper dust cover, and the small dust absorption amount is easy to cause dust to be raised, thereby affecting the sintering effect of the rotary kiln. Utility Model Content

[0005] The utility model aims to overcome the problem that the dust removal effect of the prior art is still insufficient, and provides a rotary kiln feeding device.

[0014] In a preferred embodiment, a rotary kiln body is fixedly mounted on one side of the kiln head cover, and a support plate is fixedly mounted on the bottom of the rotary kiln body, wherein the support plate is a supporting structure.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The rotary kiln feeding device can drive three dust suction ports to perform dust suction treatment on the inside of the feeding port through the operation of the dust collector, so as to absorb the dust in the material entering the feeding port. The dust is filtered out by the interception net to remove larger materials. After the dust-like materials are sucked in through the dust suction port, they are sent from the dust suction pipe to the merging pipe for merging, and finally sucked in by the dust collector. The dust collector is supported by the support rod, and the materials are guided by the slope of the top of the interception net to avoid the materials from accumulating on the top of the interception net. The dust suction effect is adjusted by adjusting the power of the dust collector, and the dust is sucked at the same time through the three dust suction ports, thereby improving the practicality and dust removal effect of the rotary kiln feeding device;

[0017] 2. The rotary kiln feeding device drives the stirring rod to stir the material inside the feeding funnel through the operation of the rotator on the top of the connecting rod, so that the dust in the material flies out, and the dust that has not been sucked into the material is sucked in through the dust suction port, thereby improving the dust removal effect of the rotary kiln feeding device and avoiding the problem that dust enters the interior of the rotary kiln and affects the sintering effect. At the same time, the top cover can protect the outer side of the rotator to avoid the material hitting the rotator when falling and causing damage to the rotator, thereby improving the practicality of the rotary kiln feeding device.

[0030] Four support rods 2 are fixedly installed on one side of the bottom of the feeding pipe 11, a vacuum cleaner 21 is fixedly installed on the bottom of the support rods 2, a merging pipe 22 is fixedly installed in the middle of the top of the vacuum cleaner 21, the merging pipe 22 is in a "T" shape, three dust suction pipes 23 are fixedly installed on three sides of the merging pipe 22, the dust suction pipe 23 is in an "L" shape, a dust suction port 24 is fixedly installed on the top of the dust suction pipe 23, an interception net 25 is fixedly installed on one side of the dust suction port 24, and the top of the interception net 25 is inclined.

[0031] Specifically, the vacuum cleaner 21 is operated so that the vacuum port 24 sucks the dust, and then the dust is sent to the merging pipe 23 and then sent to the interior of the vacuum cleaner 21 for merging, and the interception net 25 intercepts the material.
