Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening devices, and more particularly to a multi-stage screening device for highland barley flour. Background Technology
[0002] Barley flour is a special type of flour made primarily from barley. During the production process, barley flour needs to be cleaned, graded, and screened. This process typically involves a vibrating screen, which separates impurities such as dust, stones, mud, and barley husks from the barley through the vibration of the screen, thereby obtaining relatively pure barley flour.
[0003] Existing screening devices typically use double-layered fixed screens, which may not be able to effectively remove all impurities from barley flour. Impurities of different sizes and densities may require screens with different pore sizes for separation. Due to poor screening results, the final barley flour may still contain a certain amount of impurities, which will affect the quality and taste of the product. Furthermore, the remaining impurities will need to be removed through other means in subsequent processes, thereby reducing production efficiency.
[0004] Therefore, the existing screening devices typically use double-layered fixed screens, which may not be able to effectively remove all impurities from barley flour. This may result in the barley flour still containing a certain amount of impurities, affecting the quality and taste of the product and reducing production efficiency. A multi-stage screening device for barley flour can be designed, using a detachable and adjustable multi-stage screening structure to improve screening efficiency. Utility Model Content
[0005] To overcome the problem that existing screening devices typically use double-layered fixed screens, which may not be able to effectively remove all impurities from barley flour, resulting in the barley flour still containing a certain amount of impurities, affecting product quality and taste, and reducing production efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1-Figure 4 This utility model provides an embodiment of a multi-stage screening device for highland barley flour, including a screening box 1 and a screening component; the screening box 1 is provided with a detachable and assembleable screening component for multi-stage screening of highland barley flour. The screening component includes a large-hole sieve 201. The screening box 1 is provided with a large-hole sieve 201, a medium-hole sieve 202 and a small-hole sieve 203 arranged sequentially from top to bottom. The large-hole sieve 201, the medium-hole sieve 202 and the small-hole sieve 203 are all fitted with a rectangular support frame 205. The rectangular support frame 205 is symmetrically provided with two sets of snap-fit holes 206 on both sides. The rectangular support frame 205 is also symmetrically provided with two sets of rectangular snap-fit plates 207 on both sides. Multiple sets of snap-fit posts 208 are linearly installed on the inner side of the rectangular snap-fit plates 207.
[0022] Please see Figure 2-Figure 3 In this embodiment, a detachable feed pipe 102 is provided above the screening box 1, and a U-shaped snap-fit plate 103 is fixedly installed at the lower end of the feed pipe 102. First, the barley flour is poured into the screening box 1 through the feed pipe 102 for screening. A discharge pipe 106 is fixedly installed at the lower end of the screening box 1, and a column 101 is installed at each corner of the discharge pipe 106. After the barley flour has passed through multiple screening stages, the barley flour without impurities falls along the discharge pipe 106 into the receiving container for collection. The column 101 stabilizes and supports the screening box 1, improving the stability of the screening device during operation. A U-shaped snap-fit groove 104 is provided at the upper edge of the screening box 1, corresponding to the U-shaped snap-fit plate 103. U-shaped snap-fit grooves 105 are symmetrically provided on both sides of the inner wall of the screening box 1. After the screening components are assembled, the feed pipe 102 is lifted, and then the U-shaped snap-fit plate 103 drives the feed pipe 102 to be positioned and connected to the screening box 1 along the U-shaped snap-fit groove 104, and the screening of barley flour can begin.
[0023] Please see Figure 4In this embodiment, multiple sets of vibrating blocks 204 are evenly distributed on the upper ends of the large-aperture screening mesh 201, the medium-aperture screening mesh 202, and the small-aperture screening mesh 203. Each vibrating block 204 contains a vibrator (model KD2306). Driven by the vibrator, the vibrating block 204 vibrates, accelerating the screening efficiency of the screens and improving the screening effect. The locking column 208 drives the rectangular locking plate 207 to be positioned and connected to the rectangular support frame 205 through the locking hole 206. First, based on this batch of barley flour... Depending on the impurities contained in the powder, multiple sets of screens with different aperture sizes are selected. Then, the snap-fit column 208 drives the rectangular snap-fit plate 207 to be positioned and connected to the rectangular support frame 205 through the snap-fit hole 206, thereby completing the assembly of multiple sets of screens. Each pair of horizontally arranged rectangular snap-fit plates 207 has a U-shaped handle 209 fixedly installed on the upper end. After the screens are assembled, lift the U-shaped handle 209 and place the screens in the screening box 1. Then, the rectangular snap-fit plate 207 drives the screens to be positioned and connected to the screening box 1 along the U-shaped snap-fit groove 105.
[0024] During the operation, firstly, based on the impurities contained in this batch of highland barley flour, select multiple sets of sieves with different aperture sizes. Then, the clamping column 208 drives the rectangular clamping plate 207 to be positioned and connected to the rectangular support frame 205 through the clamping hole 206, thereby completing the assembly of multiple sets of sieves. Then, lift the U-shaped handle 209 and place the sieve in the screening box 1. At the same time, the rectangular clamping plate 207 drives the sieve along the U-shaped clamping groove 105 to be positioned and connected to the screening box 1. After the sieve assembly is completed, lift the feed pipe 102. Then, the U-shaped clamping plate 103 drives the feed pipe 102 along the U-shaped clamping groove 104 to be positioned and connected to the screening box 1, and the screening of highland barley flour can begin.
[0025] First, the barley flour is poured into the screening box 1 through the feed pipe 102 for screening. Figure 4 As shown, the barley flour is first screened through a large-aperture sieve 201 to remove larger impurities. Then it is further screened through a medium-aperture sieve 202 to remove medium-sized impurities. Finally, it is screened through a small-aperture sieve 203 to remove smaller impurities. During this process, the vibrating block 204 is vibrated by a vibrator to accelerate the screening efficiency and improve the screening effect. After the barley flour has passed through multiple screening stages, the impurity-free barley flour falls into the receiving container along the discharge pipe 106 for collection.
[0026] Through the above steps, based on the impurities contained in this batch of highland barley flour, multiple sets of sieves with different apertures are selected and assembled into a screening component. Then, this component is placed in screening box 1, and the highland barley flour is poured into screening box 1 for multi-stage sieving, so that the impurities in the highland barley flour are completely removed. Through the detachable and adjustable multi-stage screening structure, impurities in the highland barley flour, such as highland barley particles that have not met the crushing requirements, stones, dust, etc., can be removed more effectively, improving the purity and quality of the highland barley flour. It can also adapt to highland barley raw materials of different varieties and particle sizes, enhancing the adaptability and flexibility of the equipment, thereby improving production efficiency. This solves the problem that existing screening devices usually use double-layer fixed sieves, which may not be able to effectively remove all impurities in the highland barley flour, resulting in the highland barley flour still containing a certain amount of impurities, which will affect the quality and taste of the product and reduce production efficiency.
