Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification and screening for grain processing, in particular to a dehumidification and screening device for grain processing. Background Art

[0002] Coarse grains usually refer to grain and bean crops other than the five major crops of rice, wheat, corn, soybeans and potatoes. They mainly include: sorghum, millet, buckwheat (sweet buckwheat, bitter buckwheat), oats (naked wheat), barley, millet, sorghum, coix seed, amaranth, kidney beans (kidney beans), mung beans, adzuki beans (red beans, red beans), broad beans, peas, cowpeas, lentils (soldier beans), black beans, etc. They are characterized by short growth period, small planting area, special planting area, low yield, and generally rich in nutrients. In the process of coarse grain production, special processing equipment for coarse grains is often required. However, the existing processing equipment cannot dehumidify the coarse grains when screening and removing impurities from the coarse grains, so that the wet coarse grains are prone to mold. In addition, in the process of screening and removing impurities, the impurities after screening are inside the device, and there is no way to clean them in time. Later staff still need to clean them separately inside the device.

[0003] After searching the existing Chinese patents: A dehumidification and screening device for fine processing of grains (Announcement No.: CN208960327U), including a dehumidification and screening device and a screening device, wherein the dehumidification and screening device includes a dehumidification box, a dehumidification chamber in the dehumidification box, a grain inlet at the top of the dehumidification box, an electric heating pipe, and a power supply fixed to the outside of the dehumidification box. The screening device includes a main shaft, an outer screening roller, and an inner screening roller. The two ends of the main shaft are arranged in the dehumidification box through bearings, and one end of the main shaft is connected to a transmission box. The inner screening roller is fixedly connected to the main shaft, and the outer screening roller is arranged on the outside of the inner screening roller, and the two ends of the outer screening roller are rollingly connected to the main shaft through bearings. The utility model is provided with a dehumidification chamber surrounded by an electric heating pipe and a screening device is arranged in the dehumidification chamber. While the main shaft rotates and screens, the dehumidification effect of the electric heating pipe can be improved, which complements each other and thus has good dehumidification effect and screening effect.

[0004] Compared with the traditional dehumidification and screening device for grain processing, the above patent sets a dehumidification chamber surrounded by electric heating tubes and sets a screening device in the dehumidification chamber, which can improve the dehumidification effect of the electric heating tubes while the main shaft rotates for screening, complementing each other, thus having good dehumidification and screening effects. However, during the screening and impurity removal process of the device, the large particles of impurities after screening are still inside the device, and there is no way to remove them immediately. The staff needs to clean them separately later to discharge them.

[0005] Therefore, it is necessary to invent a dehumidification screening device for grain processing to solve the above problems. Utility Model Content

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model is a dehumidification and screening device for processing grains. The device is divided into two parts. The first part is a screening box, which is used to screen out large particles of impurities mixed in the grains. The second part is a dehumidification box, which is used to heat and dry the wet grains. When using the device, the operator can first pour the grains that need to be dehumidified and screened into the screening box, screen them first, and then dehumidify them. The operator needs to start the vibration motor in the screening box first, and then pour the grains into the screening box through the upper cover provided on the top of the screening box, through the feed pipe provided on the upper cover, and through the hopper of the feed pipe. The screening box is provided with a screen inside. When the grains fall into the screen inside the screening box through the feed pipe on the screening box, the vibration motor next to the screen will continuously vibrate and screen the grains that fall on the screen, so that the grains are screened under the sieve holes of the screen. The volume of the sieve holes on the screen is larger than that of the grains, so that the grains can pass through the sieve holes, while the larger impurities mixed in the grains remain on the screen. To remove and discharge the large impurities on the screen, the staff needs to start the hair dryer in the fan box installed behind the air inlet at the rear end of the screen. After starting the hair dryer, the wind blown by the hair dryer can pass through the air inlet to discharge the large impurities on the screen through the dust outlet at the front end. The front end of the screen is connected to a slide plate. When the wind blows, the impurities on the screen will move forward under the action of the wind, and the impurities will be quickly sent out through the slide plate connected to the front end of the screen. The grains that pass through the sieve holes on the screen will fall into the storage box in the discharge box at the bottom of the screening box. The staff can easily open the discharge box through the sliding door installed by hinges at both ends of the discharge box, and take out the storage box in the discharge box through the door handle on the sliding door.

[0017] 2. In the utility model, a dehumidification box is connected to one side of the screening box of the device. When the grains screened in the screening box are screened, the staff can directly take out the storage box at the bottom of the screening box, and pour the screened grains in the storage box into the dehumidification box next to it. The dehumidification box is also provided with an upper cover, and a feed pipe is also provided on the upper cover. The staff can pour the screened grains into the dehumidification box through the hopper on the feed pipe. During the process, the staff needs to start the two sets of heating components installed on the front mounting plate of the screening box first, and the interior of the dehumidification box can be heated by the heating components. Then the staff starts the drive motor installed in the middle of the upper cover. After the drive motor is started, the front shaft will start to rotate, so that the connecting shaft connected to the front end of the shaft will also start to rotate. Two sets of ring sleeves are installed on the connecting shaft, and stirring blades are connected to the ring sleeves, so that the stirring blades will start to rotate and stir the grains in the dehumidification box so that it can be better and more fully dehumidified during the stirring process. When the grains are almost heated and dehumidified, the staff can turn off the drive motor and the heating component, and then pull out the partition in the plate slot on one side of the dehumidification box, so that the dehumidified grains on the partition will fall down and fall into the storage box in the lower end discharge box for storage, thus completing the dehumidification and screening of the grains.

[0033] Working principle: This is a dehumidification and screening device for processing grains. The device is divided into two parts. The first part is a screening box 1, which is used to screen out large particles of impurities mixed in the grains. The second part is a dehumidification box 16, which is used to heat and dry the wet grains. When using the device, the operator can first pour the grains that need to be dehumidified and screened into the screening box 1, screen them first, and then dehumidify them. The operator needs to start the vibration motor 26 in the screening box 1 first, and then pour the grains into the screening box 1 through the upper cover 2 provided on the top of the screening box 1, the feed pipe 3 provided on the upper cover 2, and the hopper 4 of the feed pipe 3. The screening box 1 is provided with a screen 8 inside. When the grains fall onto the screen 8 inside the screening box 1 through the feed pipe 3 on the screening box 1, the vibration motor 26 next to the screen 8 will continuously vibrate and screen the grains that fall on the screen 8, so that the grains are screened under the sieve holes of the screen 8. The volume of the mesh holes on the screen 8 is larger than that of the grains, so that the grains can pass through the mesh holes of the screen 8, while the large impurities mixed in the grains with a larger volume remain on the screen 8. To remove and discharge the large impurities on the screen 8, the staff needs to start the blower 6 in the fan box 5 installed behind the air inlet 7 at the rear end of the screen 8. After the blower 6 is started, the wind blown by the blower 6 can pass through the air inlet 7 to discharge the large impurities on the screen 8 through the dust discharge port 10 at the front end. The front end of the screen 8 is connected to a slide plate 9. When the wind blows, the impurities on the screen 8 will move forward under the action of the wind, and the impurities will be quickly sent out through the slide plate 9 connected to the front end of the screen 8. The grains that pass through the sieve holes on the screen 8 will fall into the storage box 12 in the discharge box 11 at the bottom of the screening box 1. The staff can easily open the discharge box 11 through the sliding door 14 installed by hinges 13 at both ends of the discharge box 11, and use the door handle 15 on the sliding door 14 to take out the storage box 12 in the discharge box 11. A dehumidification box 16 is connected to one side of the screening box 1 of the device. After the grains that have been screened in the screening box 1 are screened, the staff can directly take out the storage box 12 at the bottom of the screening box 1, and pour the screened grains in the storage box 12 into the dehumidification box 16 next to it. The dehumidification box 16 is also provided with an upper cover 2, and the upper cover 2 is also provided with a feed pipe 3. The staff can pour the screened grains into the dehumidification box 16 through the hopper 4 on the feed pipe 3. During the process, the staff needs to start the two sets of heating components 23 installed on the front mounting plate 22 of the screening box 1 first, and the interior of the dehumidification box 16 can be heated by the heating components 23.Then the staff will start the driving motor 17 installed in the middle of the upper cover 2. After the driving motor 17 starts, the front rotating shaft 18 will start to rotate, so that the connecting shaft 19 connected to the front end of the rotating shaft 18 will also start to rotate. Two sets of ring sleeves 20 are installed on the connecting shaft 19, and the ring sleeves 20 are connected to stirring blades 21, so that the stirring blades 21 will start to rotate and stir the grains in the dehumidification box 16 so that they can be dehumidified better and more fully during the stirring process. When the grains are almost heated and dehumidified, the staff can turn off the driving motor 17 and the heating component 23, and then pull out the partition 25 in the plate groove 24 on one side of the dehumidification box 16, so that the dehumidified grains on the partition 25 will fall down and fall into the storage box 12 in the lower end discharge box 11 for storage.
