Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flour processing and screening equipment, in particular to a high square plansieve for flour processing. Background Art
[0002] The high square plansieve is suitable for grading and screening various powdery and granular materials. It is suitable for grading and screening in corn processing plants, corn starch plants, flour mills, feed mills, etc. It is an ideal grading and screening equipment for granular and powdery materials. In the process of using the high square plansieve to screen flour, since the flour particle size is finer than other materials, the fine particles have a large specific surface area and the surface energy is significantly increased, it is easy for the flour to get stuck in the mesh of the screen during screening and is difficult to fall out. In addition, the flour that falls into the screen grid is also easy to accumulate on the support net in the screen grid and is difficult to fall out, which brings great inconvenience to the screening of flour. The existing cleaning blocks are usually made of nylon cloth. When it comes to the problem of material accumulation on the support net and the screen net, they simply use the contact friction of the nylon cloth surface to assist in clearing the material, which has limited effect and is difficult to take into account all aspects. Therefore, there is an urgent need for a high square plansieve for flour processing that can assist the flour to fall smoothly during the flour screening process and ensure screening efficiency. Utility Model Content

[0021] The following is a clear and complete description of the present invention with reference to the accompanying drawings and embodiments:
[0022] like Figures 1 to 6As shown, the utility model is a high square plansieve for flour processing, comprising a frame 1, a screen box 2 is provided on the frame 1, a screen frame 3 is provided in the screen box 2; wherein the screen frame 3 is evenly divided into a plurality of screen grids 4, and a support net 5 is provided at the bottom of each screen grid 4; a pusher block 6 is movably provided in each screen grid 4, and the pusher block 6 is located on the support net 5, and its bottom is in contact with the support net 5, and a brush 7 is provided on the top of the pusher block 6, and the brush 7 is made of a flexible and deformable material to ensure that the upper screen 8 is dredged while reducing its The wear caused by this is that the screen mesh 8 is arranged on the screen frame 3 above the screen grid 4; a cleaning protrusion 9 is provided at the bottom end of the pusher block 6, and the pusher block 6 contacts the support mesh 5 by means of the cleaning protrusion 9; during operation, as the screen frame 3 vibrates in a cycle, the pusher block 6 moves in the screen grid 4, and the contact friction between the cleaning protrusion 9 and the support mesh 5 can realize the timely cleaning and dropping of the flour accumulated on the support mesh 5, and the contact between the bristles 7 and the bottom of the screen mesh 8 can be used to dredge the bottom of the screen mesh 8, thereby ensuring the smooth falling of the flour during the screening process.
[0023] In this embodiment, the mesh holes of the support net 5 are larger than the mesh holes of the screen 8, so that the support net 5 can support the pushing block 6 while providing a channel for the flour to fall smoothly, reducing the amount of flour accumulated on it, and providing assistance for improving the screening efficiency.
[0024] Furthermore, in this embodiment, the pusher block 6 is a drum-shaped structure. When the screen frame 3 vibrates, the arc-shaped structure of the pusher block 6 circumference collides with the inner wall of the screen grid 4, thereby improving its freedom of movement within the restricted range of the screen grid 4, thereby completing the dredging of the bottom of the screen 8. In addition, in this embodiment, the screen grid 4 is also preferably configured as a cylindrical structure, and the inner wall of the screen grid 4 and the outer wall of the pusher block 6 are both smooth, further improving the freedom of the pusher block 6 in the screen grid 4, ensuring the effect of cleaning and dredging the screen 8 and the support mesh 5.
[0025] Furthermore, the pusher block 6 in this embodiment is provided with a through-hole in the middle, and the bristles 7 and the cleaning protrusions 9 are arranged along the circumference of the corresponding end surfaces. The through-hole arrangement of the pusher block 6 provides space for the flour to fall, and minimizes the space occupied by the pusher block 6 inside the sieve 4, thereby ensuring the smooth fall of the flour.
[0026] Furthermore, the bottom of the cleaning block 9 is an arc-shaped structure, and its size is larger than the mesh size of the support mesh 5. This prevents the pusher block 6 from being stuck in the mesh of the support mesh 5 when it moves within the sieve grid 4. In addition, the cleaning block 9 is made of polyurethane material and has a smooth surface. At the same time, by utilizing the arc surface to contact the support mesh 5, the pusher block 6 can move smoothly on the support mesh 5. In addition, the pusher block 6 in this embodiment is also made of polyurethane material, which gives it a certain strength and flexibility, ensuring its service life while reducing wear between it and the sieve grid 4.
[0027] Furthermore, an upwardly convex guide structure 10 is formed between the four adjacent sieve grids 4, and a guide slope extending into the four sieve grids 4 on the peripheral side is formed on the guide structure 10 to provide guidance for the falling flour, so that the flour can smoothly enter the sieve grid 4 and fall through the support net 5, avoiding the flour from gathering and accumulating at the confluence of the four sieve grids 4.
[0028] When the utility model is in use, the vibration of the screen frame 3 will drive the pushing block 6 to move in the corresponding screen grid 4, thereby completing the cleaning and dredging operations of the screen mesh 8 and the support mesh 5, and can fully take into account the flour discharge problems at the upper and lower ends, ensuring the efficiency of flour screening and discharge, with a simple structure and strong practicality.
