Metering and transporting device for transporting alternative fuel into kiln tail

Abstract

The invention provides a metering and transporting device for transporting alternative fuel into a kiln tail. The metering and transporting device is characterized in that the metering and transporting device comprises is provided with a SRF material storage bin, a rotating discharge mechanism and a spiral which is provided with a rotating shaft and a rotating chain; the side end of the SRF material storage bin is provided with a discharge port, and a part of the rotating discharge mechanism is embedded in the discharge port through a bearing; and the rotating discharging mechanism is providedwith a vortex feeding channel and a gear connected with the rotating shaft in a toothing manner. The rotary discharging mechanism is rotated, and the SRF rotates to enter the center of the rotating discharging mechanism from the outside to the inside along the vortex feeding channel and the SRF can be transported to the rotating chain, an at the same time, the rotating discharge mechanism is driven by the gear to make the spiral rotate, and the SRF continues rotating along the rotating chain until the kiln tail.

Description

technical field [0001] The invention relates to the field of cement industry, in particular to a metering and transporting device for transporting alternative fuels into the kiln tail. Background technique [0002] Collect general industrial solid waste by classification, and then go through crushing, vibrating and bouncing screen, air separation, magnetic separation, eddy current, optical separation and other processes to further screen and remove the renewable resources and non-combustibles, and the remaining high calorific value General industrial solid waste is crushed to a certain particle size, that is, alternative fuel (SRF). SRF is not garbage, but a homogeneous and stable alternative fuel, which can be supplied to cement kilns to replace the use of coal in the production process. This technology It is widely used in Germany. The blending of alternative fuels in cement kilns will not reduce the production capacity and quality of cement, but also can make full use of ...

AI Technical Summary

Problems solved by technology

[0003] The metering and transportation device is used to send SRF to the cone of the decomposition furnace at the end of the rotary kiln of the cement production line, and enter the kiln for high-temperature incineration to achieve the effect of replacing coal. Since SRF is separated from a small amount of renewable resources in general industrial solid waste The pulverized matter will be dusted when it is transported and unloaded to the kiln tail. The SRF entering the kiln is easily raised by the rising high-temperature airflow from the kiln into the kiln tail smoke chamber, which increases the dust concentration in the airflow. The role of harmful components such as sulfur and alkali makes the cone of the decomposition furnace at the end of the rotary kiln easy to crust, and the dust includes heavy metal dust, organic pollutant dust, chemical reagent pollutant dust, etc., which pollutes the environment and is harmful to the health of operators. Unfavorable, at the same time, because the SRF needs to be transported to the end of the kiln for combustion, it must block moisture and keep it dry. The metering and transportation device in the prior art only solves the problem of fuel jamming or the accuracy of fuel metering, and does not Consider the problems of dust and moisture
