Abstract
Description
Technical Field
[0001] The utility model relates to a pneumatic conveying device for rice, belonging to the technical field of pneumatic conveying equipment. Background Art
[0002] Pneumatic conveyors have become important mechanical equipment in industrial and agricultural production. Pneumatic conveying is a conveying method that uses the energy of air to convey powdery and granular materials. Specifically, pneumatic conveying mainly uses the kinetic energy of air with a certain speed to complete the conveying of powdery and granular materials.
[0003] The existing pneumatic conveying device for rice conveys rice into a rice bin through a blower and a conveying pipeline. A wire mesh cylinder is installed between the conveying pipeline and the rice bin. Rice falls into the rice bin from the wire mesh cylinder, and the air generated by the blower blows out from the gaps of the wire mesh cylinder. The problems are as follows: When rice enters the wire mesh cylinder, it will collide with the inner cylinder wall. Due to the high hardness of the wire mesh cylinder, some rice will be broken. At the same time, because the rice directly falls into the rice bin from the wire mesh cylinder, the impact force will also cause some rice to be broken, resulting in a reduction in the grade and quality of the rice and causing economic losses. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a pneumatic conveying device for rice, which adds an environmentally friendly non-woven fabric lining and a conveying plate that can buffer the falling speed of rice on the inner cylinder wall of the wire mesh cylinder, can effectively reduce the breakage rate of rice, improve the grade and quality of rice, increase economic benefits, and solve the above problems existing in the background art.
[0005] The technical solution of the utility model is as follows:

The blower is connected to the inlet of the material conveying pipeline. The outlet of the material conveying pipeline is connected to the separation mechanism. A feed inlet is provided at one end of the material conveying pipeline close to the blower. The bottom of the separation mechanism is connected to the rice bin. The separation mechanism includes a wire mesh cylinder, a non-woven fabric lining, a conveying plate, and an opening. The inner cylinder wall of the wire mesh cylinder is provided with a non-woven fabric lining. Openings are provided on both the wire mesh cylinder and the non-woven fabric lining, and the openings are connected to the outlet of the material conveying pipeline. A plurality of the conveying plates are fixedly inclined left and right relative to each other from top to bottom on the inner cylinder wall of the wire mesh cylinder. The discharge end of the conveying plate located above is matched with the feed end of the conveying plate located below to form a left and right folded blanking channel.
[0007] Further, a rotary air lock is provided at the feed inlet.
[0008] Further, the feed end of the conveying plate located at the topmost is located directly below the opening.
[0009] Furthermore, the discharge end of the conveying plate at the bottom is located directly above the rice bin.
[0010] Furthermore, the non-woven fabric lining is fixed to the inner barrel wall of the wire mesh cylinder by a plurality of clips or wires.
[0011] Furthermore, one side of the conveying plate is an arc edge, and the radian of the arc edge is the same as that of the inner barrel wall of the wire mesh cylinder, and the arc edge is fixedly welded to the inner barrel wall of the wire mesh cylinder.
[0012] The positive effects of the present utility model: Adding an environmentally friendly non-woven fabric lining and a conveying plate that can buffer the falling speed of rice on the inner barrel wall of the wire mesh cylinder can effectively reduce the breakage rate of rice, improve the grade and quality of rice, and increase economic benefits; the structure is simple, the manufacturing cost is low, and it can be widely promoted and applied in rural areas.

[0016] The following further describes the present utility model in conjunction with the drawings and embodiments:
[0017] Combined with the attached Figure 1 and 2, this embodiment provides a pneumatic conveying device for rice, which includes a fan 1, a feed inlet 2, a material conveying pipeline 3, a separation mechanism 4 and a rice bin 5. The fan 1 is connected to the inlet of the material conveying pipeline 3, the outlet of the material conveying pipeline 3 is connected to the separation mechanism 4, and a feed inlet 2 is provided at one end of the material conveying pipeline 3 close to the fan 1. A air shutter (round orifice discharger) 6 is provided at the feed inlet 2. The function of the air shutter 6 is to prevent rice from being unable to enter the material conveying pipeline 3 from the feed inlet 2 due to the wind force of the fan 1, which is a well-known device in the art. The bottom of the separation mechanism 4 is connected to the rice bin 5; the separation mechanism 4 includes a wire mesh cylinder 41, a non-woven fabric lining 42, a conveying plate 43 and an opening 44. The non-woven fabric lining 42 is provided on the inner cylinder wall of the wire mesh cylinder 41. The non-woven fabric lining 42 is environmentally friendly, non-toxic and soft. The setting of the non-woven fabric lining 42 can effectively prevent rice from being broken. Openings 44 are provided on both the wire mesh cylinder 41 and the non-woven fabric lining 42, and the openings 44 are connected to the outlet of the material conveying pipeline 3. The three conveying plates 43 are fixedly inclined left and right relative to each other from top to bottom on the inner cylinder wall of the wire mesh cylinder. The discharging end of the upper conveying plate 43 matches the feeding end of the lower conveying plate 43, forming a left-right folding feeding channel.
[0018] Refer to the attached Figure 2 , the feeding end of the uppermost conveying plate 43 is located directly below the opening 44. The discharging end of the lowermost conveying plate 43 is located directly above the rice bin 5. The upper and lower conveying plates 43 on the same side are arranged parallel to each other.
[0019] Preferably, the non-woven fabric lining 42 is fixed on the inner cylinder wall of the wire mesh cylinder 41 by means of a plurality of clips or wires to prevent the non-woven fabric lining 42 from detaching.
[0020] Preferably, the conveying plate 43 is an arc-shaped plate, one side of the conveying plate 43 is an arc-shaped edge, the radian of the arc-shaped edge is the same as the radian of the inner cylinder wall of the wire mesh cylinder 41, and the arc-shaped edge is welded and fixed to the inner cylinder wall of the wire mesh cylinder 41.
[0021] Preferably, the fan 1 is a blower, which is a well-known and commonly used device in the art.
[0022] The using process of the present utility model: Start the fan 1, and the rice enters the material conveying pipeline 3 through the feed inlet 2 and the air shutter (round orifice discharger) 6. The wind force blows the rice to the outlet of the material conveying pipeline 3. Since the non-woven fabric lining 42 is provided inside the wire mesh cylinder 41, even if the rice collides with the non-woven fabric lining 42 due to the wind force, the rice will not be broken because the non-woven fabric is soft. It falls from the opening 44 of the wire mesh cylinder 41 onto the uppermost conveying plate 43, and then slides onto the rice bin 5 from the corresponding conveying plates 43 in sequence. At this time, the wind generated by the fan blows out from the gaps of the wire mesh cylinder.
