Embodiment 1
[0048] Example 1: 1T fluidization effect
[0049] Adjust the feeding angle of the feeding device to 25°, and adjust the feeding height to 790mm from the height of the combustion module, so that the height of the sand outlet is 330mm from the upper part of the fluidization module, and the angle of the upper elbow is 37°. Under the circumstances, the output of the roaster is adjusted to 1 ton / hour and the fluidization effect is good.
[0050] Under this roaster structure, the indicators of the regenerated sand after roasting are 0.09% mud content, 0.01% water content, and 0.12% reduction. Meet the theoretical design requirements of the furnace body.
Embodiment 2
[0051] Example 2: 2T fluidization effect
[0052] Adjust the feeding angle of the feeding device to 40°, adjust the feeding height to 760mm from the height of the combustion module, make the height of the sand outlet from the upper part of the fluidization module 300mm, and the angle of the upper elbow to be 40°. The output of the lower roaster was adjusted to 2 tons / hour and the fluidization effect was good.
[0053] Under this type of roaster structure, the indicators of the regenerated sand after roasting are 0.07% mud content, 0.02% water content, and 0.14% reduction. Meet the theoretical design requirements of the furnace body.
Embodiment 3
[0054] Example 3: 2.5T fluidization effect
[0055] Adjust the feeding angle of the feeding device to 50°, and adjust the feeding height to 745mm from the height of the combustion module, so that the height of the sand outlet is 250mm from the upper part of the fluidization module, and the angle of the upper elbow is 43°. The output of the lower roaster was adjusted to 3 tons / hour and the fluidization effect was good.
[0056] Under this roaster structure, the indicators of the regenerated sand after roasting are 0.07% mud content, 0.02% water content, and 0.15% reduction. Meet the theoretical design requirements of the furnace body.

Abstract
The invention specifically relates to a thermal regenerative fluidization and roasting furnace for test, comprising a roasting furnace body and a visual device. The internal situation of the roastingfurnace body can be viewed through the visual device arranged on the roasting furnace body; the visual device comprises a camera and a screen, the camera is arranged outside the roasting furnace body,and the screen is used for displaying an image shot by the camera; the visual device is made of a transparent and high-temperature resistant material, the roasting furnace body is provided with at least one visual device, and the internal situation of the roasting furnace body can be viewed through the visual device; the thermal regenerative fluidization and roasting furnace for test further comprises a feed adjusting device and a discharge adjusting device; and the feed adjusting device and the discharge adjusting device are arranged on the roasting furnace body. The thermal regenerative fluidization and roasting furnace for test improves the practical use effect of equipment, guides the design and theoretical calculation of the thermal equipment, and has wide application range and strong practicability.
Description
technical field [0001] The invention belongs to the field of casting, and in particular relates to a thermal regeneration fluidization and roasting furnace for testing. Background technique [0002] At present, the common problem faced by the domestic foundry industry is the discharge and pollution of old sand. In the environment where the state strongly advocates green environmental protection and sustainable development, the thermal regeneration equipment realizes the recycling of sand with its green and low energy consumption, which is widely used in the foundry industry. widely recognized and applied. However, the actual fluidization effect and roasting effect of thermal regeneration equipment often have a certain deviation from the theoretical design. In order to improve the actual use effect of the equipment and guide the optimal design and theoretical calculation, an experimental device is needed to further verify and test the fluidization effect. and roasting effect...
