Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically to a screening device for flour production and processing. Background Technology
[0002] Screening devices in flour production and processing are key equipment for ensuring flour quality, removing impurities, and optimizing particle size distribution. Their core function is to separate large particles and foreign objects from raw materials through physical sieving technology, thereby improving the purity and processing performance of flour. By rationally selecting and configuring screening devices, flour production enterprises can significantly improve product quality, reduce production costs, and meet food safety standards.
[0003] When screening flour, the screening plate is prone to clogging. Large particles of impurities get stuck on the inner wall of the screening plate's through holes, causing blockage. Therefore, personnel need to disassemble the screening plate regularly and clear the through holes on its surface to ensure its normal operation. However, disassembling the screening plate will cause the device to stop working, resulting in reduced work efficiency. Currently, the screening device does not have a structure for real-time unblocking of the screening plate, and this problem should be addressed.
[0004] Therefore, a screening device for flour production and processing is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a screening device for flour production and processing in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A screening device for flour production and processing includes a base, a box body, and a box door. The box body is fixedly installed on the top of the base, and the box door is slidably installed on the top of the base. A discharge port is provided on one side of the box body. A flour collection box is provided inside the box body. An impurity collection box is provided on the top of the base and is located below the discharge port. Screening mechanisms for screening and processing flour are provided on the outside and inside of the box body. An anti-clogging mechanism is provided inside the box body to prevent clogging of the screening mechanism.
[0008] Furthermore, the screening mechanism includes a guide rail, a guide rail is fixedly provided on one outer wall of the housing, a motor is fixedly provided on the top of the guide rail, a threaded rod is rotatably provided on the inner wall of the guide rail, and the top end of the threaded rod passes through the surface of the guide rail and is fixedly connected to the output end of the motor. A slider is threadedly connected to the surface of the threaded rod, and the slider is slidably disposed inside the guide rail. A crossbar is fixedly provided at one end of the slider, an extension rod is fixedly provided at the top of the crossbar, and a screening plate is fixedly provided at the other end of the extension rod.
[0009] Furthermore, there are two sets of extension rods, and both sets of extension rods are U-shaped. One end of each set of extension rods is fixedly connected to both ends of the crossbar, and the other end of each set of extension rods extends into the interior of the box and is fixedly connected to the top of the screening plate.
[0010] Furthermore, the screening plate is inclined and adapted to the box body, with the side wall of the screening plate fitting against the inner wall of the box body. The bottom of the inner side of the discharge port is inclined, and the inclination of the bottom of the discharge port is equal to the inclination of the screening plate.
[0011] Furthermore, the anti-clogging mechanism includes a T-shaped groove, the inner wall of the box is provided with a T-shaped groove, a T-shaped block is slidably provided on the inner wall of the T-shaped groove, a horizontal plate is fixedly provided on the surface of the T-shaped block, and a clearing rod is fixedly provided on the top of the horizontal plate, and the clearing rod is adapted to the through hole of the screening plate.

The surface of the horizontal plate is provided with slots, and a total of several slots are provided and evenly distributed on the horizontal plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a screening mechanism to enable the flour on its surface to move longitudinally. The screening mechanism sieves the flour, and the flour after impurity removal falls into the flour collection box. Large particles of impurities remain on the surface of the screening mechanism. As the screening mechanism causes the large particles of impurities on its surface to move upward, when the large particles of impurities correspond to the discharge port, the large particles of impurities slide down the surface of the screening mechanism and pass through the discharge port into the impurity collection box, thereby completing the screening of the flour. During the operation of the screening mechanism, it will come into contact with the surface of the anti-clogging mechanism. The anti-clogging mechanism can keep the screening mechanism unobstructed, thereby avoiding clogging. This device can reduce downtime and thus improve work efficiency. Attached Figure Description

[0023] like Figures 1 to 3As shown, a screening device for flour production and processing includes a base 1, a box 2, and a door 3. The box 2 is fixedly mounted on the top of the base 1, and the door 3 is slidably mounted on the top of the base 1. A discharge port 4 is provided on one side of the box 2. A flour collection box 5 is provided inside the box 2, and an impurity collection box 6 is provided on the top of the base 1, located below the discharge port 4. Screening mechanisms 7 for screening and processing flour are provided both outside and inside the box 2. Figure 1 , Figure 2 As shown, specifically, the screening mechanism 7 includes a guide rail 701. The guide rail 701 is fixedly mounted on one outer wall of the housing 2. A motor 702 is fixedly mounted on the top of the guide rail 701. A threaded rod 703 is rotatably mounted on the inner wall of the guide rail 701, and the top end of the threaded rod 703 penetrates the surface of the guide rail 701 and is fixedly connected to the output end of the motor 702. A slider 704 is threadedly connected to the surface of the threaded rod 703, and the slider 704 is slidably disposed inside the guide rail 701. A crossbar 705 is fixedly mounted on one end of the slider 704, and an extension rod 706 is fixedly mounted on the top of the crossbar 705. The other end of 06 is fixedly provided with a screening plate 707. There are two sets of extension rods 706, and both sets of extension rods 706 are U-shaped. One end of each set of extension rods 706 is fixedly connected to both ends of the crossbar 705. The other end of each set of extension rods 706 extends into the interior of the box 2 and is fixedly connected to the top of the screening plate 707. The screening plate 707 is inclined and adapted to the box 2. The side wall of the screening plate 707 is in contact with the inner wall of the box 2. The bottom of the inner side of the discharge port 4 is inclined, and the inclination of the bottom of the discharge port 4 is equal to the inclination of the screening plate 707.
[0024] More specifically, when the motor 702 starts, its output drives the threaded rod 703 to rotate, thereby causing the slider 704 to slide longitudinally. This, in turn, causes the crossbar 705, the extension rod 706, and the screening plate 707 to move longitudinally. The flour to be screened is placed on the surface of the screening plate 707, and the flour falls through the through holes of the screening plate 707. Large particles of impurities remain on the top of the screening plate 707. The longitudinal movement of the crossbar 705 causes the two sets of extension rods 706 to move longitudinally at the same time. The ends of the two sets of extension rods 706 connected to the screening plate 707 can support the two sides of the screening plate 707 respectively, thereby ensuring the smooth lifting and lowering of the screening plate 707. When the screening plate 707 moves upward and corresponds to the discharge port 4, the large particles of impurities on the surface of the screening plate 707 slide down the surface of the screening plate 707 and slide down through the inner bottom of the discharge port 4 into the impurity collection box 6.
[0025] The interior of the housing 2 is equipped with an anti-clogging mechanism 8 to prevent clogging of the screening mechanism 7, such as... Figure 2 , Figure 3As shown, specifically, the anti-clogging mechanism 8 includes a T-shaped groove 801. The inner wall of the box 2 is provided with a T-shaped groove 801. A T-shaped block 802 is slidably provided on the inner wall of the T-shaped groove 801. A horizontal plate 803 is fixedly provided on the surface of the T-shaped block 802. A clearing rod 804 is fixedly provided on the top of the horizontal plate 803, and the clearing rod 804 is adapted to the through hole of the screening plate 707. There are two sets of both the T-shaped groove 801 and the T-shaped block 802, and the opposite surfaces of the two sets of T-shaped blocks 802 are fixedly connected to the two sides of the horizontal plate 803 respectively. The surface of the horizontal plate 803 is provided with slots 805, and a number of slots 805 are provided and evenly distributed on the horizontal plate 803.
[0026] More specifically, the screening plate 707 moves downward, allowing the top of the unblocking rod 804 to pass through the through hole of the screening plate 707, thereby pushing out the impurities stuck in the inner wall of the through hole and preventing the through hole from becoming blocked. The horizontal plate 803 is moved laterally, causing the T-shaped block 802 to slide, thereby disassembling the horizontal plate 803 and the unblocking rod 804. The two sets of T-shaped grooves 801 limit the two sets of T-shaped blocks 802 respectively, and the two sets of T-shaped blocks 802 limit the two sides of the horizontal plate 803. The flour can fall into the flour collection box 5 through several slots 805.
[0027] In summary: Unscreened flour is added to the inside of the housing 2, placing it on the surface of the screening mechanism 7. The screening mechanism 7 allows the flour on its surface to move longitudinally, sieving the flour. The flour after impurity removal falls into the flour collection box 5. Large particles of impurities remain on the surface of the screening mechanism 7. As the screening mechanism 7 moves these large particles upward, when they align with the discharge port 4, they slide down the surface of the screening mechanism 7 and pass through the discharge port 4 into the impurity collection box 6, thus completing the screening of the flour. During operation, the screening mechanism 7 comes into contact with the surface of the anti-clogging mechanism 8, which helps to keep the screening mechanism 7 clear and prevents clogging. This device can reduce downtime and improve work efficiency.
