Referring to fig. 4, the sand separating mechanism 100 of the present invention includes a sand removing cylinder 1 placed vertically; a contraction part 11 is arranged below the sand removing cylinder 1, and a guide part 13 is arranged above the sand removing cylinder; the guide portion 13 has an arc-shaped structure, and the radian of the arc-shaped structure is 90 degrees; the tail end of the guide part 13 is connected with a dust and fruit separator 21; the outside of the guide part 13 of the sand removing cylinder 1 is connected with a feed hopper 14.

The granular fruit materials are added into the desanding cylinder 1 from a feed hopper 14; compressed air flow is sprayed out of the multiple layers of air blowing pipe groups, the size of the air flow is adjusted or controlled to blow up granular fruit materials in the desanding cylinder 1, and multiple air flows which are uniformly distributed are formed in the vertical direction due to the fact that the air guide pipes 16 of the two adjacent layers of air blowing pipe groups are arranged in a three-dimensional crossing mode; preferably, the airway tube 16 of the present invention has at least 12 air outlets 161, such as 15-20 air outlets. An air flow group with a large covering area is formed, and the fruit material is ensured to be blown up. The sand grains have high density and small volume and fall to the bottom of the sand removing cylinder 1. Preferably, the bottom of the contraction part 11 is provided with a filter screen 12; the mesh size of the filter screen 12 is 6 meshes or 12 meshes, sand can smoothly pass through, and fruit materials are blocked.

Airflow with proper density is formed, so that fruit materials are reasonably distributed in the vertical direction in the desanding cylinder 1; the fruit materials are prevented from being accumulated at the bottom of the desanding cylinder 1 due to the fact that the air flow distribution is too sparse; the fruit material accumulation at the top of the sand removing cylinder 1 caused by the over dense air flow distribution is also avoided.
The multi-layer blowing pipe groups arranged from top to bottom form deep air flow in the vertical direction, so that fruit materials are prevented from falling to the bottom of the sand removing cylinder 1 due to the fact that the falling speed is too high. The air-blowing pipe group of the present invention has at least three layers, preferably four, five or six layers. The distance between two adjacent layers of blowing pipe sets is 20-25 cm. The distance can be adapted by the person skilled in the art to be larger or smaller depending on the type of fruit to be treated and the intensity of the air flow.

The sand removing cylinder 1 generates self-vibration by using the blowing power of feeding or air flow in the cylinder, and promotes the separation of sand grains and fruit materials. For balancing the sand removing cylinder 1, a counter weight can be added at a proper position of the supporting plate 15 by those skilled in the art.
Referring to fig. 6, each of the groups of insufflation tubes has three air ducts 16; the air outlet 161 of the air duct 16 in the middle is vertically upward, and the air outlets 161 of the air ducts 16 on both sides form an included angle of about 10 degrees with the vertical direction. The air ducts 16 on both sides and the air flow of the middle air duct 16 form intersection, so that the fruit material is blown more stably.
Referring to fig. 7, a plurality of air nozzles 17 are uniformly and annularly arranged on the inner wall of the contraction part 11 of the sand removing cylinder 1; the number of the air nozzles 17 of the present invention is at least 15; and blowing the fruit materials which leak through the air blowing pipe group back.
The invention arranges a plurality of layers of blowing pipe groups on the desanding cylinder, and uses air flow to blow up the granular fruit materials, and the sand grains fall to the bottom of the cylinder, thereby realizing the separation of the fruit materials and the sand grains. The top of the barrel is provided with a dust outlet and a discharge outlet, and the dust and the fruit materials are separated at the dust outlet and the discharge outlet. The invention realizes the separation of fruit materials, dust and sand grains by utilizing the airflow. The burden of subsequent cleaning equipment is reduced, and the water consumption for cleaning is greatly reduced.
In summary, the present invention provides a dry type sand separation air flow conveying device, which utilizes air flow to separate fruit materials from sand grains and dust through a sand separation mechanism and a dust and fruit separator. And then the fruit materials enter a pneumatic conveying pipe, and the fruit materials in the inlet pipe are conveyed to the adjacent workshop or equipment of the next working procedure through compressed air flow. The conveying speed is high, the occupied space of the pipeline is small, and the operation efficiency is high. Realizes the continuous operation of sand removal and dust removal of the fruit materials. The residual dust on the fruit materials is removed by the water spray nozzle before air flow conveying, so that the water consumption of subsequent cleaning operation is greatly reduced, partial products can even replace the cleaning operation, the investment and the operation cost of cleaning equipment are reduced, and the generation amount of waste water is greatly reduced.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
