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 invention relates to the field of baking, in particular to a coffee bean microwave baking machine which comprises a baking mechanism. The baking mechanism comprises a metal shell, a wave-transparent container placed in the metal shell and a microwave generating device installed outside the metal shell. And the other side of the metal shell is provided with a door which can be opened and closed and is used for taking and placing the wave-transparent container. According to the coffee bean baking method, the coffee beans are baked by adopting microwave heating, the microwave baking technology is characterized in that electromagnetic waves penetrate through the coffee beans, water molecules vibrate to generate heat, so that the baking effect is achieved, and the original flavor and nutritional ingredients of the coffee beans can be better reserved. Meanwhile, the penetrability and uniformity of microwave heating are good, the coffee beans on the outer layer and the inner layer are heated at the same time, even if the limited penetration depth and the energy distribution characteristic of microwaves are considered, the temperature difference between the coffee beans on the inner layer and the outer layer is small, the overall baking effect cannot be greatly influenced, and therefore all the coffee beans have the good baking quality.

The utility model relates to a crank rocker swing distributing machine, which is characterized in that one end of a feeding belt is positioned below a feeding hopper, the other end of the feeding belt is positioned above a fixed blanking hopper, the bottom of the fixed blanking hopper is connected with a swing distributing machine, the swing distributing machine is arranged on an equipment frame, and a mesh belt is arranged below the swing distributing machine. The swinging material distributing machine can spread materials on the mesh belt through left-right horizontal swinging and comprises a material distributing chute, a bearing seat, a rocker, a crank body, a sliding block and a gear motor, the bottom of the material distributing chute is fixedly connected with the top of a rotating shaft of the material distributing chute, and the rotating shaft of the material distributing chute is sleeved with the bearing seat. The bottom of the rotary shaft of the material distribution chute is rotatably connected with one end of the rocker, the rocker is slidably connected with the slider, the slider is rotatably connected with the crank body through the knuckle bearing, and the crank body is in transmission connection with the gear motor. The baking machine has the obvious advantages of being small in occupied area, labor-saving, high in baking quality, more energy-saving, more environment-friendly and the like.

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.
