[0017] 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.
[0018] like Figure 1 , Figure 2 As shown, this embodiment discloses a crushed material dust separation device, including an outer cylinder 3 and an inner cylinder 4. The outer cylinder 3 is a cylindrical structure with an opening at the bottom. An air outlet channel 32 is provided on the outer wall of the outer cylinder 3. The air outlet channel 32 is located on both sides of the outer cylinder 3. The inner cavity of the outer cylinder 3 is connected to the air outlet channel 32. The air outlet channel 32 is connected to an external pipe to discharge dust.
[0019] The outer wall of the top of the outer cylinder 3 is provided with a channel opening 33. A feeding pipe 2 is installed on the top of the outer cylinder 3. The channel opening 33 is connected to the feeding pipe 2. The feeding pipe 2 conveys plastic crushed material into the channel opening 33 by wind power. The crushed material contains dust.
[0020] The inner cylinder 4 is a cylindrical structure, inserted into the outer cylinder 3. The inner diameter of the outer cylinder 3 is larger than the outer diameter of the inner cylinder 4. The outer cylinder 3 and the inner cylinder 4 are coaxially arranged, and the air outlet channel 32 is located radially outside the inner cylinder 4. The upper wall of the inner cylinder 4 abuts against the upper wall of the outer cylinder 3, and the channel opening 33 communicates with the inner cavity of the inner cylinder 4. The outer cylinder 3 includes a base plate 31 at the bottom, which is fixedly connected to a second base plate 41.
[0021] The bottom of the inner cylinder 4 is fixedly connected to the material bucket 1. The inner cylinder 4 includes a base plate 41 located at the bottom. The base plate 41 has a ring-shaped structure. The bottom surface of the base plate 41 is attached to the upper surface of the material bucket 1. The base plate 41 is fixedly connected to the upper surface of the material bucket 1.
[0022] like Figure 2 As shown, the outer cylinder 3 is also provided with an air outlet channel 32 on its outer circumference, and the outer wall of the inner cylinder 4 is provided with multiple through holes 42. The through holes 42 penetrate the wall of the outer cylinder 3, and the inner cavity of the inner cylinder 4 is connected to the inner cavity of the outer cylinder 3 through the through holes 42. The crushed material introduced through the channel opening 33 enters the inner cavity of the inner cylinder 4, and the dust in the crushed material is discharged from the air outlet channel 32 through the through holes 42 under the action of wind. The diameter of the through hole 42 is smaller than the outer diameter of the crushed material.
[0023] The inner cavity of the material bucket 1 is connected to the inner cavity of the inner cylinder 4. Specifically, the top of the material bucket 1 is provided with a feed inlet 11, which is connected to the bottom of the outer cylinder 3.
[0024] The outer cylinder 3 is equipped with a fixed seat 5. Specifically, the fixed seat 5 is located above the material bucket 1, and the fixed seat 5 is equipped with a fixed rod 6, which is fixedly connected to the outer cylinder 3. The fixed seat 5 is vertically opposite to the channel opening 33. The fixed seat 5 is conical, with the tip of the cone pointing towards the channel opening 33. The crushed material entering from the channel opening 33 impacts the conical surface of the fixed seat 5, generating vibration to shake off the powder on the crushed material. The crushed material enters the material bucket 1 from the feed inlet 11, thereby reducing the amount of powder on the crushed material entering the material bucket 1. During use, the bottom of the material bucket 1 is the discharge port, which is in a closed state. As airflow enters the material bucket 1, the pressure inside the material bucket 1 increases, making it difficult for dust to enter the feed inlet 11. Most of the dust flows out from the air outlet 32, thereby reducing the amount of dust in the crushed material.
[0025] like Figure 2 As shown, the outer wall of the fixed base 5 is provided with multiple air holes 51, which penetrate the conical surface of the fixed base 5. The fixed base 5 has a cavity 52 inside, which communicates with the air holes 51. The fixed base 5 is equipped with an air duct 53, which communicates with the cavity 52. An air inlet device is connected to the outside of the air duct 53. Air is introduced through the air duct 53 and discharged from the air holes 51, so as to generate an upward airflow at the bottom of the inner cylinder 4, thereby making it easier to discharge the powder from the through hole 42 and reducing the amount of powder entering the material bucket 1.
[0026] like Figure 2 As shown, it also includes a support 7, with a motor 72 mounted at the bottom of the support 7. A shaft 73 is mounted at the output end of the motor 72, and the shaft 73 is rotatable along its own axial direction. The shaft 73 is located above the fixed base 5, and a rotating rod 74 is mounted on the shaft 73. The length direction of the rotating rod 74 is along the radial direction of the shaft 73. The cross-section of the rotating rod 74 perpendicular to its length direction is triangular, with the hypotenuse facing upwards. Figure 3 As shown, the rotation tangent direction of the rotating rod 74 is P, and the vertical direction of the triangular inclined plane of the rotating rod 74 is Q. The Q direction is diagonally upward. When the rotating rod 74 rotates, it impacts the crushed material, shakes off the powder on the crushed material, and at the same time changes the direction of movement of the crushed material, causing the crushed material to move diagonally, increasing the time for the crushed material to pass through the inner cylinder 4, increasing the number of impacts of the crushed material, thereby reducing the powder on the crushed material.
[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
