Description

Technical Field

[0001] This utility model relates to the field of grain, specifically a grain raw material storage and grading dust removal device. Background Technology

[0002] During the loading and unloading of bulk materials such as grain, a large amount of dust is easily generated due to the friction between grain or material particles and the action of airflow. This not only threatens the health of operators, but also damages the surrounding environment and equipment. Therefore, dust removal is required when raw grain enters and leaves the warehouse.

[0003] The publication number CN220617654U provides an adjustable dust suppression device for grain unloading, including an outer cylinder that runs vertically through the upper and lower parts of the outer cylinder. The upper end of the outer cylinder is the inlet, and the lower end is the outlet. The outer cylinder is equipped with a flow diversion component, which includes a cone and a pull rod.

[0004] The aforementioned adjustable dust suppression device achieves the effect of reducing dust, but during unloading, dust will remain between the grain particles, making it inconvenient to filter some of the dust while unloading, and the filtered dust is inconvenient to collect and clean.

[0022] 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.

[0023] Example 1, combined with Figures 1-4 A grain raw material storage and grading dust removal device includes a cylinder 1, a feed inlet 2 at the top of the cylinder 1, a dust removal component 3 installed inside the cylinder 1, a collection component 4 installed outside the cylinder 1, an upper cone 5 installed at the bottom of the inside of the cylinder 1, four support rods 6 fixedly installed between the upper cone 5 and the inner wall of the cylinder 1, and a lower cone 7 fixedly installed at the bottom of the upper cone 5.

[0024] See Figure 2 Furthermore, the dust removal component 3 includes a screen cylinder 8, which is fixedly installed inside the cylinder 1 near the bottom. A material distribution plate 9 is fixedly installed on the top of the upper conical body 5 inside the screen cylinder 8. A guide ring 10 is fixedly installed on the outside of the screen cylinder 8 near the bottom. A discharge trough 11 is opened through the outside of the cylinder 1 and on the outer ring of the guide ring 10. A discharge port is provided at the bottom of the cylinder 1, through which the grain is discharged.

[0025] The bottom diameter of the cylinder 1 is smaller than the top diameter, and the height of the upper cone 5 is greater than the height of the lower cone 7. The grain flows at a slower speed as the gap between the upper cone 5 and the cylinder 1 gradually decreases, thereby reducing the diffusion of dust and impurities.

[0026] The inner wall of the sieve cylinder 8 is inclined, and the top diameter of the sieve cylinder 8 is larger than the bottom diameter. The sieve cylinder 8 is used to filter out fine dust in the grain, and at the same time, the grain slides down through the sieve cylinder 8 to reduce the falling speed.

[0027] The fabric tray 9 is located directly below the feed inlet 2. Several support columns are fixed inside the discharge trough 11. The dust slides outward through the guide ring 10 and is discharged through the discharge trough 11.

[0028] Specifically, grain enters the cylinder 1 through the feed inlet 2, is distributed on the surface of the screen cylinder 8 by the distribution plate 9, slides down through the screen cylinder 8, and filters out some of the fine dust particles remaining in the grain. The grain flow rate is reduced by the upper cone 5 and the lower cone 7, further reducing the spread of dust. The filtered dust slides outward through the guide ring 10 and is discharged through the discharge chute 11.

[0029] Example 2, see Figure 3Furthermore, based on Embodiment 1, a set of threaded grooves 12 is provided on the bottom of the outer side of the cylinder 1, a positioning ring 13 is fixedly installed on the outer side of the cylinder 1 and at the top of the discharge trough 11, the collection assembly 4 includes a collection sleeve 14, the collection sleeve 14 is movably connected to the outer side of the cylinder 1, a collection groove 15 is opened inside the collection sleeve 14, a number of observation windows 16 are installed on the outer side of the collection sleeve 14, and a feed groove 17 is opened on the inner wall of the collection sleeve 14 near the top.

[0030] The collection sleeve 14 is connected to the outside of the cylinder 1 by a threaded connection through the threaded groove 12. The collection sleeve 14 is installed through the threaded groove 12, which facilitates the disassembly, assembly and cleaning of the collection sleeve 14.

[0031] The feed trough 17 and the discharge trough 11 correspond to each other. The observation window 16 is transparent inside and out. The inside of the collection sleeve 14 can be observed through the glass of the observation window 16. Dust enters the collection trough 15 through the feed trough 17.

[0032] Specifically, the collection sleeve 14 is connected to the outside of the cylinder 1 through the threaded groove 12, so that the feed trough 17 corresponds to the discharge trough 11. After the dust is discharged through the discharge trough 11, it enters the collection trough 15 through the feed trough 17 for collection, so as to prevent the dust from spreading into the outside air. The observation window 16 is used to observe the amount of dust inside. The collection sleeve 14 is removed for regular cleaning.

[0033] In actual operation, grain is added into cylinder 1 through feed inlet 2, and the flow rate is reduced by the upper cone 5 and lower cone 7 to reduce dust stirring, and then discharged through discharge port at the bottom of cylinder 1.

[0034] During dust removal, the grain is dispersed onto the surface of the screen cylinder 8 by the cloth disc 9, and slides down through the screen cylinder 8. During the sliding process, some of the fine dust particles remaining in the grain are filtered out. The filtered dust slides outward through the guide ring 10 and is discharged through the discharge chute 11.

[0035] During collection, the collection sleeve 14 is connected to the outside of the cylinder 1 through the threaded groove 12, so that the feed trough 17 corresponds to the discharge trough 11. After the dust is discharged through the discharge trough 11, it enters the collection trough 15 through the feed trough 17 for collection, so as to prevent the dust from spreading into the outside air. The observation window 16 is used to observe the amount of dust inside. The collection sleeve 14 is removed for regular cleaning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
