Automatic control continuous material guiding and distributing sealed feeding device

Abstract

The invention relates to an automatic control continuous material guiding and distributing sealed feeding device which comprises a rotary hopper, a fixed hopper, a partitioned feeding device, a cone self-pressurization double-layer sealing structure, a telescopic seal, a hopper rotation keeping device, a variable speed driving device, an upper cover and an overpressure feedback sealing device. The device has the beneficial effects that the device adopts a method of distributing materials by an eccentric spiral surface rotating hopper and controlling a fixed hopper to feed materials in different areas by a computer, so that the feeding uniformity is improved, and the height difference of the material surface in the fixed hopper can be ensured to be less than 200mm; by adopting the overpressure feedback sealing device, the problem of dust and smoke leakage caused by overlarge operation pressure in the kiln chamber can be solved, the pollution to the environment is reduced, the safety of equipment is ensured, the repair and maintenance of the equipment are reduced, the production efficiency is improved, and the requirements of serial and large-scale development of the lime shaft kiln are met, and the new-era requirements of cleanness, environmental protection and green water and green mountains are met.

Description

technical field [0001] The invention relates to the technical field of kiln equipment, in particular to an automatic control continuous material guide cloth sealing feeding device. Background technique [0002] At present, the rotary feeding sealing device of the existing active lime shaft kiln is generally in the form of single material bell feeding, double material bell feeding, single layer rotary distributor feeding and other forms. No matter which feeding method is used, the uniformity of the distribution of the size of the feeding material, the durability of the device, and the sealing of the dust during the feeding process cannot well meet the requirements of the process production, especially when the operating pressure in the kiln is due to accidents. When it is greater than the set value, the dust from the kiln chamber and the feeding device will leak out, causing the on-site operating environment to be relatively harsh, and the frequency of equipment maintenance a...
