Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of dry fruit shell crushing, and particularly relates to a dry fruit shell crushing device. BACKGROUND

[0002] In the traditional processing of dry fruits such as walnuts, the fruit shells are regarded as solid waste, and most of them are incinerated as fuel, which not only causes great pollution to the environment, but also wastes high-quality resources.

[0003] When carrying out underground oil extraction operations, it is necessary to use equipment to crush the rocks buried in the ground to make the rocks have cracks. After the crushing equipment is removed, in order to avoid the stress closure of the cracks of the underground rocks, which affects the downhole oil extraction equipment, it is necessary to fill the support material into the cracks. At present, the commonly used filling method is chemical material filling, and a small amount of organic shell crushing particles are also used for filling. Compared with chemical material filling, using the particles of the crushed fruit shells as support materials can reduce pollution to the environment, improve soil structure, and reduce the manufacturing cost of the filling materials, making the underground oil extraction work more environmentally friendly. It can also reduce carbon emissions by reducing incineration of fruit shells.

[0004] In addition to being used as a filling material for rock cracks, the shell particles after processing and screening can also be used as raw materials for water treatment filter materials. After processing techniques such as crushing and polishing, the organic shell filter material has characteristics such as high hardness, wear resistance, and good compression resistance. At the same time, the organic shell particles can also be used as biomass activated carbon and applied to water treatment filter materials due to their high porosity and groups such as hydroxyl, carboxyl, and phosphoryl groups, which have the effect of adsorbing heavy metals and other harmful substances.

[0005] At present, there are few devices specially developed for crushing organic shells. The crushing of organic shells is realized by means of the crushing of other existing substances.
