Description

Technical Field

[0001] This utility model relates to the technical field of rice polishing machines, specifically a dust collection and circulation device for rice polishing machines. Background Technology

[0002] The working principle of the dust collection and recycling device of the rice polishing machine is to use a negative pressure suction device to discharge the generated dust in time during the polishing process, and then collect and recycle the dust through the filtration system.

[0003] The existing dust collection and circulation devices for rice polishing machines cannot collect dust from the inner wall of the machine during use. This causes dust to accumulate during long-term polishing of rice, resulting in low dust collection efficiency. In addition, while the dust is filtered by the filtration system, larger particles are intercepted, while smaller particles may pass through the filter and enter the circulation system, making it impossible for the machine to collect dust. Therefore, the equipment has limitations. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The dust collection and circulation device of this rice polishing machine uses a second motor to drive the fan to rotate through the control controller. The fan rotates on the inner wall of the fan box to generate airflow and form negative pressure. The gas generated by the rotation of the inner wall of the machine is transmitted to the inner wall of the dust collection box through the air pipe, and the generated dust is discharged in time. The dust is collected and recycled through the inner wall of the dust collection box. The filter bag filters the gas on the inner wall of the machine, and larger dust particles are blocked to the outer wall of the filter bag. The filtered gas is discharged through the exhaust port.

[0015] 2. The dust collection and circulation device of this rice polishing machine, through the control controller, uses a first motor to drive the rotating wheel to rotate. The rotating wheel drives the driven wheel to rotate through the transmission belt, causing the two beaters to rotate and beat the dust blocking the outer wall of the filter bag. The dust falls to the inner wall of the collection frame. By pulling the baffle with external force, the baffle drives the circular plate to press the spring, so that the collection frame is in contact with the outer wall of the baffle to achieve the limit. When personnel collect dust, by rotating the baffle, the elastic force of the spring pushes the circular plate, so that the collection frame is separated from the outer wall of the baffle, making it easier for personnel to collect dust.

A beater plate 23 is fixedly mounted on the beater 14 and is correspondingly positioned on the front side of the filter bag 13. When the beater 14 drives the beater plate 23 to rotate, This allows the clapper 23 to strike the filter bag 13, thereby knocking off the dust on the filter bag 13; a square plate 17 is fixedly installed on the inner wall of the dust collection box 20, a fixing ring 15 is fixedly installed on the top of the square plate 17, a filter bag 13 is installed on the bottom of the fixing ring 15, a material collection frame 11 is slidably connected to the inner wall of the dust collection box 20, a baffle 10 is installed on the outer wall of the material collection frame 11, a round plate 18 is fixedly installed on the outer wall of the baffle 10, a spring 19 is movably sleeved on the outer wall of the baffle 10, a fan box 22 is fixedly installed on the outer wall of the dust collection box 20, a second motor 12 is fixedly connected to the outer wall of the fan box 22, a fan 21 is fixedly mounted on the power output shaft of the second motor 12, and a controller 5 is fixedly installed on the outer wall of the dust collection box 20;

[0024] In the above structure, untreated rice is placed into the polishing machine by installing the machine body 2. After the machine is started, the rice is rinsed with water to remove impurities and dust from the surface of the rice. After being washed, the rice enters the grinding chamber of the polishing machine. In the grinding chamber, the rice rubs against the grinding plate, causing the rice grain skin to be subjected to friction and the skin to be wiped off, thereby achieving the purpose of polishing. The rice residue and debris are discharged from the polishing machine by the airflow and vibration in the grinding chamber.

[0025] In a preferred embodiment: the controller 5 is electrically connected to the first motor 6, and there are two beaters 14, with the two beaters 14 located on the outer walls of the driven wheel 9 and the rotating wheel 7, respectively;

[0026] In the above structure, the first motor 6 drives the rotating wheel 7 to rotate by the control controller 5. The rotating wheel 7 drives the driven wheel 9 to rotate through the transmission belt 8, so that the two beaters 14 rotate to beat the dust blocking the outer wall of the filter bag 13.

[0027] In a preferred embodiment: the bottom of the fixing ring 15 is fixed to the top of the filter bag 13, and the outer wall of the filter bag 13 overlaps with the outer wall of the flap 14.

[0028] In the above structure, the gas generated by the operation of the inner wall of the machine body 2 is transmitted to the inner wall of the dust collection box 20 through the air pipe 16. The filter bag 13 filters the gas on the inner wall of the machine body 2, and the larger dust particles are blocked to the outer wall of the filter bag 13. The filter bag 13 is repeatedly tapped by the beater 14, so that the dust falls to the inner wall of the collection frame 11.

[0029] In a preferred embodiment: the controller 5 is electrically connected to the second motor 12, and an exhaust port 4 is fixedly installed on the outer wall of the dust collection box 20;

[0030] In the above structure, the second motor 12 drives the fan 21 to rotate by the control controller 5, so that the fan 21 rotates on the inner wall of the fan box 22 to generate airflow and form negative pressure, which discharges the generated dust in time, and collects and recycles the dust through the inner wall of the dust collection box 20.

[0031] In a preferred embodiment: one end of the spring 19 is fixed to the outer wall of the circular plate 18, and the other end of the spring 19 is fixed to the inner wall of the baffle 10;

[0032] In the above structure, by pulling the baffle 10 with external force, the baffle 10 drives the circular plate 18 to press the spring 19, so that the collecting frame 11 fits against the outer wall of the baffle 10 to achieve a limit. When personnel collect dust, by rotating the baffle 10, the elastic force of the spring 19 pushes the circular plate 18, so that the collecting frame 11 separates from the outer wall of the baffle 10, making it easier for personnel to collect dust.

[0033] In a preferred embodiment: there are two baffles 10, and the two baffles 10 are symmetrically arranged with the material collection frame 11 as the center;

[0034] In the above structure, two baffles 10 are symmetrically arranged around the collection frame 11, so that the two baffles 10 can stably limit the collection frame 11, preventing vibration during equipment operation and causing the powder on the inner wall of the collection frame 11 to detach from the inner wall of the dust collection box 20.

[0035] In a preferred embodiment: one end of the air pipe 16 is fixed to the inner wall of the body 2, and the other end of the air pipe 16 is fixed to the inner wall of the dust collection box 20.

[0036] In the above structure, when the fan 21 rotates to generate airflow, it generates negative pressure. The dust on the inner wall of the machine body 2 is adsorbed onto the inner wall of the air pipe 16, so that the air pipe 16 transmits the dust to the inner wall of the dust collection box 20.

[0037] In a preferred embodiment: the outer wall of the fixing ring 15 is fixedly connected to the inner wall of the square plate 17, and the three fixing rings 15 are evenly distributed on the inner wall of the square plate 17.

[0038] In the above structure, three fixing rings 15 are evenly distributed on the inner wall of the square plate 17. The fixing rings 15 support the filter bag 13, so that the filter bag 13 can effectively filter on the inner wall of the dust collection box 20. The square plate 17 effectively blocks unfiltered dust and avoids the reduction of dust removal quality.

[0039] Working principle: The second motor 12 drives the fan 21 to rotate via the controller 5, causing the fan 21 to rotate on the inner wall of the fan housing 22, generating airflow and creating negative pressure. The gas generated by the rotation of the inner wall of the machine body 2 is transmitted to the inner wall of the dust collection box 20 via the air pipe 16, where the generated dust is promptly discharged. The dust is collected and recycled through the inner wall of the dust collection box 20. The filter bag 13 filters the gas from the inner wall of the machine body 2, blocking larger dust particles to the outer wall of the filter bag 13. The first motor 6 drives the rotating wheel 7 to rotate via the controller 5. The rotating wheel 7 drives the driven wheel 9 to rotate via the transmission belt 8, causing the two beaters 14 to rotate and drive the beaters 23 to beat the dust on the outer wall of the filter bag 13. The dust falls to the inner wall of the collection frame 11. The baffle 10 is pulled by external force, and the baffle 10 drives the circular plate 18 to press the spring 19, so that the collection frame 11 is in contact with the outer wall of the baffle 10 to achieve a limit. When personnel collect dust, by rotating the baffle 10, the elastic force of the spring 19 is used to push the circular plate 18, so that the collection frame 11 is separated from the outer wall of the baffle 10, making it easier for personnel to collect dust.
