Description

Technical Field

[0001] This utility model relates to the field of rice husk processing technology, and in particular to a rice husk conveying device. Background Technology

[0002] Physicochemical properties of rice husks: Rice husks consist of several parts, including the outer glume, inner glume, glumes, and spikelet rachis. The outer glume has bristle-like hairs on the top. After the rice is dehulled, the rice husks are collected and stored together.

[0003] In existing technologies, rice husks are generally transported using screw conveyors, which use rotating helical blades to move the rice husks along the pipe, or by belt conveyors. However, when using screw conveyors, the rice husks are prone to getting stuck on the blades, requiring regular cleaning. Belt conveyors, with their open design, are prone to dust generation, and some pneumatic conveying devices are inconvenient for dust cleaning. The silica dust (which is hard) in the rice husks can accelerate the wear of the inner wall of the pipe, especially at bends where perforation and leakage may occur, requiring frequent replacement. Therefore, a rice husk conveying device is proposed to solve the above problems. Utility Model Content

The feed hopper is connected to the top of the frame, the blower is located on the left side of the frame, and the discharge pipe is connected to the right side of the frame. It also includes a distributing roller, multiple dispersing blades, and multiple electrostatic bars. The distributing roller is rotatably disposed within the frame, the multiple dispersing blades are disposed within the frame and located directly below the distributing roller, and the multiple electrostatic bars are staggered within the frame. The frame is provided with a drive mechanism for driving the distributing roller and the multiple dispersing blades to rotate.

[0005] Preferably, the drive mechanism includes a motor, a first rotating rod, a second rotating rod, two pulleys, and a synchronous belt. The motor is located on the left side of the frame. One end of the first rotating rod is coaxially connected to the output shaft of the motor, and the other end is rotatably connected to the right side wall of the frame. One end of the second rotating rod is rotatably connected to the right side wall of the frame, and the other end extends to the left side of the frame. The two pulleys are coaxially fixedly sleeved on the first rotating rod and the second rotating rod, respectively, and are connected by the synchronous belt. The material distribution roller is coaxially fixedly sleeved on the second rotating rod, and the plurality of dispersing blades are all connected to the first rotating rod.

[0009] Preferably, an arc-shaped opening is provided on the right side of the frame, and a dust collection plate is slidably disposed inside the frame and extends through the arc-shaped opening to the outside of the frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] like Figure 1-3 As shown, the present invention proposes a rice husk conveying device, which includes a frame 1, a feed hopper 2, a blower 3, and a discharge pipe 4. The feed hopper 2 is connected to the top of the frame 1, the blower 3 is located on the left side of the frame 1, and the discharge pipe 4 is connected to the right side of the frame 1. It also includes a distributing roller 5, multiple dispersing blades 6, and multiple electrostatic bars 8. The distributing roller 5 is rotatably disposed inside the frame 1, the multiple dispersing blades 6 are disposed inside the frame 1 and located directly below the distributing roller 5, and the multiple electrostatic bars 8 are staggered inside the frame 1. The frame 1 is provided with a drive mechanism for driving the distributing roller 5 and the multiple dispersing blades 6 to rotate.

[0021] In this utility model, a support frame is fixedly installed on the left side of the frame 1, the fan 3 is installed on the support frame and the air outlet is connected to the frame 1, and the discharge pipe 4 is connected to the right side of the frame 1. By using the drive assembly to drive the distribution roller 5 and multiple dispersing blades 6 to rotate, a small portion of the rice husks is first transported and then dispersed to facilitate dust removal. After the electrostatic rod is connected to high voltage DC, the air around the discharge needle or electrode wire on the surface of the rod is ionized, generating a large number of free electrons and positive and negative ions to form a "corona layer". The dust collection plate (positive electrode) forms an electric field force of "positive and negative attraction" with the negatively charged dust, and the dust is strongly adsorbed onto the surface of the dust collection plate.

[0022] In an optional embodiment, the drive mechanism includes a motor 71, a first rotating rod 72, a second rotating rod 73, two pulleys 74, and a synchronous belt 75. The motor 71 is located on the left side of the frame 1. One end of the first rotating rod 72 is coaxially connected to the output shaft of the motor 71, and the other end is rotatably connected to the right side wall of the frame 1. One end of the second rotating rod 73 is rotatably connected to the right side wall of the frame 1, and the other end extends to the left side of the frame 1. The two pulleys 74 are coaxially fixedly sleeved on the first rotating rod 72 and the second rotating rod 73, respectively, and are connected by synchronous belt drive. The material distribution roller 5 is coaxially fixedly sleeved on the second rotating rod 73, and multiple dispersing blades 6 are all connected to the first rotating rod 72.

[0023] In an optional embodiment, the material distribution roller 5 is provided with multiple material distribution grooves, and multiple dispersing blades 6 are distributed in a ring array on the first rotating rod 72.

[0024] It should be noted that the two pulleys 74 are larger at the top and smaller at the bottom. The starting motor 71 drives the first rotating rod 72 to rotate, which in turn drives the second rotating rod 73 to rotate through the two pulleys 74 and the synchronous belt 75. After the rice husks are transported in a small amount and evenly, they are then broken up.

[0025] In an optional embodiment, the frame 1 has rod-retrieving slots on both the front and rear sides, and multiple telescopic rods 10 are connected to the left and right side walls of the frame 1. Pull plates 9 are provided on both the front and rear sides of the frame 1. The telescopic ends of the two telescopic rods 10 on the same side are connected to the pull plates 9 on the same side. Multiple electrostatic rods 8 are respectively arranged on the opposite side of the two pull plates 9.

[0026] In an optional embodiment, buckles are provided on opposite sides of the two pull plates 9 to fix the pull plates 9 to the frame 1.

[0027] It should be noted that the two pull plates 9 are fixed and disassembled to the frame by means of buckles. The two pull plates 9 are used to block the two rod-taking slots to prevent the rice husks from being thrown out and pulled during transportation. The telescopic rod 10 can be used to connect the pull plates 9 and pull the pull plates 9 at the same time. The electrostatic rod 8 can be replaced by setting the rod-taking slots.

[0028] In an optional embodiment, an arc-shaped opening is provided on the right side of the frame 1, and a dust collection plate 11 is slidably disposed inside the frame 1, extending through the arc-shaped opening to the outside of the frame 1.

[0029] It should be noted that after the conveying is completed, the dust is also attracted by the electrostatic bar 8. After the power to the electrostatic bar 8 is stopped, the dust falls onto the dust collection plate 11 for collection and centralized treatment.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
