Description

Technical Field

[0001] This utility model relates to the field of biomass fuel, specifically a rice husk screening device. Background Technology

[0002] Biomass fuels include fuels made from organic materials such as plant materials and animal waste. Due to their advantages such as high calorific value, high purity, non-corrosiveness to boilers, and complete combustion, biomass fuels are widely used. Rice husks, as an excellent raw material for biomass fuels, are widely utilized in biomass fuel production and processing enterprises. However, the collected rice husks contain a large amount of impurities, including larger weeds, twigs, leaves, and smaller particulate dust. If the rice husks are directly added to the burner, these impurities will not only affect the normal combustion of the rice husks and reduce their calorific value, but the small dust particles in the rice husks will also be stirred up during the feeding process, polluting the entire operating space. Therefore, it is essential to filter the rice husks before feeding them into the burner.

[0003] According to the published patent 201620041723.0, a rice husk screening device, it includes multiple floating screens mounted on a frame. These screens are spaced vertically, with the mesh diameter gradually decreasing from top to bottom. The screens are connected to a vibration mechanism, which drives the screens to vibrate. When rice husk material is fed into the top screen, the vibration mechanism causes the screens to vibrate, resulting in the rice husks falling from the top screen. Larger impurities are screened off. As the mesh diameter gradually decreases, the rice husks eventually remain on the middle screen. Smaller particles and dust fall off the screen. This screening device can separate rice husks from impurities, ensuring the cleanliness of the rice husk material fed to the burner. However, in developing this invention, the inventors discovered that at least the following problems remain unresolved in the prior art: although feeding rice husk material into the top screen and vibrating the screen causes the rice husks to fall from the top screen, larger impurities are screened off. As the mesh diameter of the sieve gradually decreases, the rice husks eventually settle on the middle sieve. Smaller particles and dust fall off the sieve, solving the problem of a large amount of debris mixed in with the rice husks, including larger weeds, twigs, and leaves, as well as smaller dust particles. If the rice husks are directly put into the burner, the debris inside the husks will not only affect the normal combustion of the rice husks and reduce their calorific value, but also, in use, traditional rice husk screening devices, although using sieves to screen the rice, are prone to clogging during the screening process, affecting the function of the sieve. Moreover, the large amount of dust generated is poorly collected, and the dust is still stirred up after falling due to the vibration of the device. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rice husk screening device to solve the technical problems of the current traditional rice husk screening device, which, although it uses a screen to screen rice, the filter screen is easily clogged during the screening process, affecting the function of the screen. Moreover, the large amount of dust generated is poorly collected, and the dust is still stirred up after falling because the device needs to vibrate.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A rice husk screening device is designed, including a device housing, and further comprising:

[0006] Multiple screening screens are fixed inside the device housing;

[0007] A cleaning mechanism is inserted inside multiple screening screens. The cleaning mechanism includes a first rotating rod, through which multiple screening screens are inserted. Multiple rotating plates are fixed on both sides of the first rotating rod, and cleaning brushes are fixed on the top of the multiple rotating plates. The top of the cleaning brushes is attached to the screening screens.

[0008] The first exhaust fan blade is installed at the bottom outer end of the first rotating rod.

[0009] Preferably, a water tank is installed at the bottom of the device housing, a dual-axis motor is installed on one side of the top inside the water tank, a second rotating rod is connected to the bottom of the dual-axis motor, a second exhaust fan blade is installed at one end of the second rotating rod inside the water tank, and the water level in the water tank is not higher than the second exhaust fan blade, and an electrostatic generator is installed at the front end of the water tank.

[0010] Preferably, the bottom of the device housing has a square hole, a mesh is installed inside the square hole, a first rotating rod passes through the mesh, and a dual-axis motor is connected to one end of the first rotating rod located inside the mesh.

[0011] Preferably, an electrostatic plate is installed at the rear end of the device housing, the electrostatic plate is connected to an electrostatic generator, a vibration motor is installed on the top of one side of the device housing, and multiple hoppers are connected to the other side of the device housing.

[0012] Preferably, a feed hopper is connected to one side of the top of the device housing, and one end of a hinge is rotatably connected to one side of the front end of the device housing, with a housing baffle fixed to the other end of the hinge.

[0013] Preferably, one end of a water pipe is connected to the top of one side and the bottom of the other side of the water tank, and the other end of the water pipe is detachably connected to a pipe cap.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model combines a first rotating rod, a rotating plate, and a cleaning brush. A dual-axis motor drives the rotating plate and cleaning brush to rotate, and the rotating cleaning brush cleans the surfaces of multiple screening screens, preventing clogging. Furthermore, the rotating rod also drives the first and second exhaust fan blades to rotate, drawing dust generated during screening downwards into a water tank for collection. This solves the problems of traditional rice husk screening devices, which, while using screens to screen rice, often experience clogging during screening, affecting their function. Additionally, the large amount of dust generated is poorly collected, and the dust is often stirred up again after falling due to the device's vibration.

[0016] 2. This utility model combines a device housing and an electrostatic plate. The electrostatic plate is placed inside the rear end of the device housing. During the screening process, dust generated by multiple screening screens can be electrostatically adsorbed and collected by the electrostatic plate. When used in conjunction with the exhaust fan blades, it can achieve a dual collection effect. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A rice husk sieving device, see [link to example]. Figures 1 to 2The device includes a housing 1 and multiple screening screens 2, each fixed inside the housing 1. A cleaning mechanism extends through the screening screens 2 and includes a first rotating rod 201 with multiple screening screens 2 extending through its exterior. Multiple rotating plates 202 are fixed to both sides of the first rotating rod 201, and cleaning brushes 203 are fixed to the top of each rotating plate 202, with the top of the cleaning brushes 203 adhering to the screening screens 2. A first exhaust fan blade 204 is installed at the bottom of the first rotating rod 201. When cleaning the multiple screening screens 2 is required, a dual-axis motor 205 is first turned on. The dual-axis motor 205 drives the first rotating rod 201 and a second rotating rod 206, which in turn drives the multiple rotating plates. The rotation of 202 causes multiple rotating plates 202 to drive multiple cleaning brushes 203 to rotate, thereby cleaning the surfaces of multiple screening screens 2 simultaneously and preventing clogging of the screening screens 2. At the same time, the first rotating rod 201 and the second rotating rod 206 drive the first exhaust fan blade 204 and the second exhaust fan blade 207 to rotate, which can draw the dust generated by screening by the screening screens 2 downward into the water tank 101, thereby collecting and treating the dust. This solves the technical problem of traditional rice husk screening devices, which, although using screens to screen rice, are prone to clogging inside the screens during the screening process, affecting the function of the screening screens 2. Moreover, the large amount of dust generated is poorly collected, and the dust is still stirred up after falling due to the vibration of the device.

[0022] For details, see Figure 1 The bottom of the device housing 1 is equipped with a water tank 101. A dual-axis motor 205 is installed on one side of the top of the water tank 101. A second rotating rod 206 is connected to the bottom of the dual-axis motor 205. A second exhaust fan blade 207 is installed at one end of the second rotating rod 206 inside the water tank 101. The water level in the water tank 101 is not higher than the second exhaust fan blade 207. An electrostatic generator 301 is installed at the front end of the water tank 101.

[0023] Further, see Figure 1 The bottom of the device housing 1 has a square hole 208, and a partition net 209 is installed inside the square hole 208. A first rotating rod 201 passes through the partition net 209, and a dual-axis motor 205 is connected to one end of the first rotating rod 201 located inside the partition net 209.

[0024] It is worth noting that, see Figure 1An electrostatic plate 3 is installed at the rear end of the device housing 1. The electrostatic plate 3 is connected to the electrostatic generator 301. A vibration motor 103 is installed on the top of one side of the device housing 1. Multiple hoppers 102 are connected to the other side of the device housing 1. By setting the electrostatic plate 3 at the rear end of the device housing 1, the dust generated by the multiple screening screens 2 can be electrostatically adsorbed and collected by the electrostatic plate 3 during the screening process. When used in conjunction with the exhaust fan blades, it can achieve a dual collection effect.

[0025] It is worth noting that, see Figure 2 The top side of the device box 1 is connected to the feed hopper 104, and the front side of the device box 1 is rotatably connected to one end of the hinge 105. The other end of the hinge 105 is fixed to the box baffle 106.

[0026] It is worth mentioning that, see Figure 2 One end of a water pipe 107 is connected to the top of one side and the bottom of the other side of the water tank 101, and the other end of the water pipe 107 is detachably connected to a pipe cover 108.

[0027] When using a rice husk sieving device, first turn on the dual-shaft motor 205. The dual-shaft motor 205 will drive the first rotating rod 201 and the second rotating rod 206. The first rotating rod 201 will drive multiple rotating plates 202 to rotate, and the multiple rotating plates 202 will drive multiple cleaning brushes 203 to rotate, thereby cleaning the surfaces of multiple sieving screens 2 simultaneously and preventing the sieving screens 2 from clogging. At the same time, the first rotating rod 201 and the second rotating rod 206 will drive the first exhaust fan blade 204 and the second exhaust fan blade 207 to rotate, which can draw the dust generated by the sieving screens 2 downwards into the water tank 101, thereby collecting and treating the dust. The electrostatic plate 3 is set at the rear end of the device housing 1. During the sieving process of the sieving screens 2, the dust generated by multiple sieving screens 2 can be collected by electrostatic adsorption through the electrostatic plate 3. When used in conjunction with the exhaust fan blades, a dual collection effect can be achieved.
