Description

Technical Field

[0001] This utility model relates to the field of medicinal material processing technology, specifically to a sieving and impurity removal device for processing Polygonatum sibiricum. Background Technology

[0002] The rhizome of Polygonatum can be used medicinally. It is sweet in taste and neutral in nature, and enters the spleen, lung, and kidney meridians. According to different shapes, it is commonly known as large Polygonatum, chicken-head Polygonatum, and ginger-shaped Polygonatum. It has the effects of replenishing qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. Large Polygonatum is a thick, fleshy, nodular mass. The nodules can be more than 10cm long, 3-6cm wide, and 2-3cm thick. The surface is light yellow to yellowish-brown. Chicken-head Polygonatum is a nodular, curved columnar shape, 3-10cm long and 0.5-1.5cm in diameter. Ginger-shaped Polygonatum is a long, nodular mass of varying lengths. There are often several nodules connected together. The surface is grayish-yellow or yellowish-brown and rough. There is a protruding disc-shaped stem scar on the upper side of the nodule, with a diameter of 0.8-1.5cm.

[0003] During the linear vibrating sieving process, because Polygonatum contains mucilage and starch (content can reach more than 40%), these components easily form a sticky surface after drying. As a result, ordinary linear screens in a single vibration mode cannot easily remove the powder and debris adhering to the surface of Polygonatum, which can easily reduce the quality of Polygonatum.

[0004] Therefore, we propose a sieving and impurity removal device for processing Polygonatum odoratum to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a sieving and impurity removal device for processing Polygonatum sibiricum, comprising a frame 1, a vacuum cleaner 2 and a vortex blower 3 installed at the lower part of the frame 1, buffer springs 4 installed around the top of the frame 1, and a screen box 5 installed on the buffer springs 4, a vibration motor 6 installed at the bottom of the screen box 5, and a polyurethane elastic screen plate 7 installed inside the screen box 5, with a strip air knife 8 mounted above the polyurethane elastic screen plate 7, and the strip air knife 8 connected to the vortex blower 3 via a flexible hose, a fixing frame 9 installed on the frame 1, and a hopper 10 installed on the fixing frame 9, with a dust suction nozzle 11 and a nylon brush roller 12 respectively installed in the hopper 10, and the dust suction nozzle 11... The hopper 10 is connected to the vacuum cleaner 2 via a corrugated pipe. A geared motor 13 is installed on the outside of the hopper 10, and the output shaft of the geared motor 13 is fixedly connected to the nylon brush roller 12. The geared motor 13 drives the nylon brush roller 12 on both sides inside the hopper 10 to rotate. After the material is fed in, it works in conjunction with the suction nozzle 11 to initially remove surface impurities before the material enters the sieve box 5. The suction nozzle 11 and the vacuum cleaner 2 use negative pressure to reduce the load of subsequent screening. The mechanical vibration generated by the vibration motor 6 and the high-pressure airflow generated by the vortex fan 3 and the strip air knife 8 work together to effectively peel off the powder adhering to the surface of Polygonatum odoratum, solving the problem that it is not easy to remove debris in a single vibration mode.

[0028] like Figure 2 As shown, in some embodiments, the screen box 5 is inclined, and the polyurethane elastic screen plate 7 is parallel to the screen box 5. The polyurethane elastic screen plate 7 usually uses steel wire rope as the skeleton material. In addition, polyurethane itself has a very high elastic modulus, so it has a high load-bearing capacity and wear resistance.

[0029] like Figure 2 As shown, in some embodiments, the bottom of the sieve box 5 is provided with an oversize discharge port 14 and an undersize discharge port 15, and the oversize discharge port 14 and the undersize discharge port 15 are located at the low position of the sieve box 5. The oversize discharge port 14 is used to discharge the Polygonatum odoratum material, while the undersize discharge port 15 is used to discharge powder and debris.

[0030] like Figure 2 As shown, in some embodiments, the oversize discharge port 14 is flush with the lower end of the polyurethane elastic screen plate 7, and the undersize discharge port 15 is located below the polyurethane elastic screen plate 7. The linear vibration force generated by the vibration motor 6 acts on the screen plate, so that the material is evenly distributed on the screen surface. Large particles move on the screen surface and are discharged from the oversize discharge port 14, while small particles fall into the space below through the screen holes and are discharged from the undersize discharge port 15, thus realizing the screening operation.

[0031] like Figure 2 As shown, in some embodiments, a rectangular frame 16 is installed on the top of the sieve box 5, and the strip air knife 8 is fixed on the rectangular frame 16. The strip air knife 8 is provided with at least 3 strips. The rectangular frame 16 is used for the installation and fixing of the strip air knife 8. The strip air knife 8 is a device specially designed to blow out a strong and high-speed airflow to blow away dust, dry water stains, and cool down.

[0032] like Figure 2 As shown, in some embodiments, baffles 17 are provided on both sides of the inner wall of the hopper 10, and the dust suction nozzle 11 is fixed to the bottom of the baffle 17. The baffle 17 is used for the installation and fixing of the dust suction nozzle 11, and at the same time for protecting the dust suction nozzle 11 to avoid direct impact with the material.

[0033] like Figure 2 As shown, in some embodiments, the nylon brush roller 12 is located below the dust suction nozzle 11, and the nylon brush roller 12 is mounted on both ends of the inside of the hopper 10 by bearings. The nylon brush roller 12 is a tool widely used in the industrial field. Due to its high elasticity and wear resistance, its main functions include cleaning, polishing, dust removal and surface treatment.

[0034] like Figure 4 As shown, in some embodiments, gears 18 are installed on the nylon brush rollers 12, and the two nylon brush rollers 12 are connected by meshing of the gears 18. One of the nylon brush rollers 12 is driven to rotate by the gear reducer motor 13, and the other nylon brush roller is driven to rotate together by the meshing action of the gears 18.

[0035] During use, the Polygonatum material is fed into the hopper 10. The nylon brush rollers 12 on both sides inside the hopper 10 are driven to rotate by the geared motor 13. The moving brush rollers will contact the surface of the material. The bristles will bend and rub continuously during rotation, removing powder, impurities or residues from the surface of the material. The negative pressure suction of the suction nozzle 11 and the vacuum cleaner 2 (which uses a motor-driven fan to generate suction to suck dust and particulate matter into the equipment, and then separates and collects them through the filtration system) reduces the subsequent screening load, so that the surface impurities are initially brushed off before the material enters the screen box 5. The linear vibration force generated by the vibrating motor 6 acts on the screen plate, so that the material is evenly distributed on the screen surface. Large particles move on the screen surface and are discharged from the oversize discharge port 14, while small particles fall into the space below through the screen holes and are discharged from the undersize discharge port 15, thus realizing the screening operation. The high-pressure airflow generated by the vortex blower 3 and the strip air knife 8 works synchronously to effectively peel off the surface material adhering to the Polygonatum.

[0036] In summary, the nylon brush rollers 12 on both sides of the hopper 10 are driven to rotate by the geared motor 13. After the material is fed in, they work together with the dust suction nozzle 11 to initially remove surface impurities before the material enters the screen box 5. The negative pressure suction of the dust suction nozzle 11 and the dust collector 2 reduces the load on subsequent screening. The mechanical vibration generated by the vibration motor 6 and the high-pressure airflow generated by the vortex blower 3 and the strip air knife 8 work together to effectively peel off the powder adhering to the surface of Polygonatum odoratum, solving the problem of not being able to remove debris in a single vibration mode.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
