2results about How to "Improve baking quality" patented technology

This invention relates to a low-temperature oxidative roasting pretreatment method and supporting equipment for gold-bearing pyrite. The method includes: raw material preparation; humidification and cooling; low-temperature oxygen-enriched roasting; and roasted sand collection. The supporting equipment includes a batching bin, the bin outlet of which is connected to the feed hopper inlet via an elevator, and the feed hopper outlet connected to the fluidized bed furnace inlet via a conveyor belt. A spraying device is mounted on the conveyor belt. Atomized temperature-regulating and water-replenishing device and a temperature sensor are installed in the upper and middle combustion spaces of the fluidized bed furnace. An online oxygen analyzer is installed on the flue gas duct at the top of the fluidized bed furnace, and is sequentially connected to a waste heat boiler, a cyclone dust collector, an electrostatic precipitator, and an acid production system. The air inlet at the bottom of the fluidized bed furnace is connected to a blower via an air duct. This invention achieves full oxidation of gold-bearing pyrite under low-temperature, oxygen-enriched, and low-gas-velocity conditions, resulting in loose and porous roasted sand and a significantly increased gold and silver exposure rate, providing important technical support for the comprehensive utilization of the valuable components of gold-bearing pyrite.

The utility model relates to the field of ovens, in particular to a dust removal mechanism of a dust-free oven, which comprises a baking cabinet and a filter box arranged on the baking cabinet, a dust removal chamber and a heating chamber are formed in the filter box, the interior of the dust removal chamber is partitioned by a partition plate to form an air inlet cavity, a fan is arranged in the air inlet cavity, an air inlet is arranged on the partition plate, and the heating chamber is arranged in the air inlet cavity. The dust removal chamber is internally connected with a dust removal filter element through an installation support, the end, close to the air inlet cavity, of the dust removal filter element is connected with a filter screen, the other end of the dust removal filter element is connected with an air collecting cover, and the air collecting cover is connected with an air outlet pipeline. The dust removal efficiency is improved through the filtering effect of the dust removal filter element, the filtered clean air is guided to the heating chamber through cooperation of the air collecting cover and the air outlet pipeline, dust carried by the air and entering the baking machine cabinet is reduced, and therefore the cleanliness of the baking environment is guaranteed, and the baking quality of products is improved.
