Dry-method sand-fruit separation device

Abstract

The invention relates to the technical field of dry-type separation of materials, and provides a dry-method sand-fruit separation device. The dry-method sand-fruit separation device comprises a sand removal cylinder which is vertically arranged, wherein at least three layers of air blowing pipe groups are arranged in the sand removal cylinder from top to bottom; each layer of air blowing pipe group comprises three or four air guide pipes which are arranged in parallel at equal intervals; a plurality of vertically upward air outlets are formed in pipe bodies of the air guide pipes at equal intervals; compressed air is introduced into the air guide pipes and is vertically and upwards sprayed out from the air outlets; and the air guide pipes of two adjacent layers of air blowing pipe groups form an included angle of 90 degrees in the space. Therefore, the plurality of layers of air blowing pipe groups are arranged in the sand removal cylinder, granular fruit materials are blown up by utilizing airflow, and sand grains fall to the bottom of the cylinder, so that the separation of the fruit materials and the sand grains is realized. A dust outlet and a discharging hole are formed in thetop of the cylinder, so that the separation of dust and the fruit materials is realized. According to the dry-method sand-fruit separation device, the dry-type separation of the fruit materials, thedust and the sand grains is realized by utilizing the airflow, so that the burden of subsequent equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of material dry separation, and in particular relates to a dry separation device for sago. Background technique [0002] Fruit and vegetable processing companies usually need to clean the raw materials. Vegetable and fruit raw materials usually contain mud or dust, and continuous cleaning operations require a large amount of clean water and generate a large amount of waste water. Wastewater discharge requires special sewage treatment equipment, which increases production costs. [0003] For some granular raw materials, such as hawthorn, walnut or longan, which are mixed with sand particles, the sand particles will be deposited at the bottom of the equipment after cleaning, and regular cleaning is required to avoid damage to the equipment. [0004] These processes have increased production costs and equipment repair and maintenance costs, thereby increasing the cost of the product to compress profit margins...
