Referring to fig. 1, the invention provides a dry method sand-fruit separation device, which comprises a sand removing cylinder 1 which is vertically arranged; 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 guide part 13 is also connected with a discharge port 22 with a downward opening and a dust outlet 21 with an upward opening; the outside of the guide part 13 of the sand removing cylinder 1 is connected with a feed hopper 14.

Preferably, the feeding conveyor 4 is arranged above the feeding hopper 14, and the discharging conveyor 41 is arranged below the discharging port 22.

With reference to fig. 2, a plurality of layers of blowing pipe sets are arranged in the desanding cylinder 1 from top to bottom; each layer of blowing pipe group comprises 3-5 air guide pipes 16 which are arranged in parallel at equal intervals; a plurality of air outlets 161 which are vertically upward are arranged on the tube body of the air duct 16 at equal intervals; compressed air is introduced into the air duct 16 and is vertically sprayed upwards from the air outlet 161; the air ducts 16 of the two adjacent layers of the blowing tube groups form an included angle of 90 degrees in space.

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 screen 12; the mesh size of the screen 12 is 6 meshes or 12 meshes, sand grains can smoothly pass through, and fruit materials are blocked.

The distance between two adjacent air outlets 161 on the air duct 16 is set to 5-10cm, such as 5, 6, 7, 8 or 9cm, according to the type of fruit material to be processed. 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; and also avoids fruit material gathering at the top of the sand removing cylinder 1 caused by too dense air flow distribution.

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 fruit material is blown up by the air current, and the movement direction is changed into horizontal through the arc-shaped structure of the guide part 13; the blowing force of the air flow is weaker, and the fruit material flows out from the discharge hole 22; the dust is light and is scattered from the dust outlet 21. Furthermore, the dust collection cover 2 is arranged right above the dust outlet 21 to collect dust.

Further, the feed hopper 14 of the present invention is provided with a pneumatic door 141; a level gauge 142 is arranged at the upper part of the feed hopper 14; when the level gauge 142 detects that the fruit materials in the feed hopper 14 are accumulated to a preset position, a signal is sent, and the pneumatic door 141 opens the fruit materials to fall into the sand removal cylinder 1; the automatic feeding and continuous processing of the fruit materials are realized.

Preferably, the outer wall of the sand removing cylinder 1 is connected with a support plate 15 in an annular mode; the support plate 15 is movably sleeved and fixed on a guide rod 31 of the platform frame 3; the guide rod 31 is sleeved with a vibration spring 32; the number of the guide rods 31 is at least three, preferably 6 to 8. 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. 3, 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. 4, 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.

In summary, the invention provides a dry-method sand-fruit separation device, wherein a plurality of layers of blowing pipe sets are arranged on a sand removing cylinder, granular fruit materials are blown up by airflow, sand particles fall to the bottom of the cylinder, and therefore the separation of the fruit materials and the sand particles is realized. 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.

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.
