Description

Technical Field

[0001] The utility model belongs to the field of air separation devices, in particular to an air separation machine with a screening function. Background Art

[0002] After the wood is cut into shavings, some heavy impurities such as small stones are inevitably present. If these heavy impurities with high hardness enter the processing equipment, they will damage the processing equipment and affect the processing performance of the particleboard. Therefore, the sand and stone impurities in the shavings need to be removed. After removing the sand and stone impurities, the shavings are of different sizes. In order to facilitate the production of particleboard, the shavings need to be air-sorted so that qualified shavings are screened out and oversized shavings are reworked. Therefore, we designed an air separator that can not only screen sand and stone impurities but also screen large and small shavings. Utility Model Content

[0016] A wind separator with screening function, such as Figure 1 、 2As shown in Figure 3, it includes a box body 1, one side of the box body 1 is connected with a blowing pipe 2, the other side is connected with a discharge pipe 3, the top side of the box body 1 is connected with a feeding pipe 4, and a receiving box 5 is detachably installed on the bottom of the box body 1. A tilted transverse pipe 6 is fixedly installed on the box body 1, and the transverse pipe 6 is connected with the blowing pipe 2. A screen tube 7 is rotatably installed on one end of the transverse pipe 6. The screen tube 7 is coaxially arranged with the transverse pipe 6, and the screen tube 7 is rotatably installed on the transverse tube 6 through a bearing. The screen tube 7 is fixedly installed on the inner periphery of the bearing, and the outer periphery of the bearing is fixedly installed on the transverse tube 6. The screen tube 7 is rotatably installed on the box body 1 through a bearing seat. The outer periphery of the screen tube 7 is fixedly connected to the inner periphery of the bearing seat, and the outer periphery of the bearing seat is fixedly installed on the box body 1. Several sieve holes 8 are opened on the screen tube 7, and several tilted baffles 9 are fixedly installed on the inner periphery of the screen tube 7. The baffles 9 are evenly distributed along the circumference of the axis of the screen tube 7. The box body 1 is provided with a driving mechanism for driving the screen tube 7 to rotate. The utility model has a simple structure and ingenious design. The screen tube 7 is driven to rotate by a driving mechanism, and the mixed wood shavings and sand and gravel impurities can be driven to rotate by the baffle 9. The wood shavings and sand and gravel impurities are lifted up and then fall down many times during the movement, thereby achieving multiple screening and extending the air selection channel. The sand and gravel impurities are finally screened from the sieve holes 8 into the receiving box 5. The small-sized wood shavings that meet the requirements can enter the discharge pipe 3 through the wind direction assistance of the blowing pipe 2, and the large-sized wood shavings finally fall into the receiving box 5 at the end of the screen tube 7, which can meet market demand and is suitable for promotion. The large-sized shavings finally fall into the receiving box 5 at the end of the screen tube 7, thereby screening out the sand and gravel impurities and the large-sized shavings.

[0017] Specifically, as shown in the figure, the driving mechanism of this embodiment includes a conical gear ring 20, which is fixedly mounted on the outer periphery of the sieve pipe 7 and coaxially arranged. A bevel gear 21 is meshed and matched on one side of the conical gear ring 20. The bevel gear 21 is rotatably mounted on the housing 1. The housing 1 is fixedly mounted with a first motor 22. The rotating shaft of the first motor 22 is fixedly connected to the bevel gear 21 and coaxially arranged. The rotating shaft of the first motor 22 is rotatably mounted in a reserved hole opened on the housing 1 through a bearing and is fixedly connected to the bevel gear 21 through a connecting shaft. The rotating shaft of the first motor 22 drives the bevel gear 21 to rotate, and the bevel gear 21 can drive the conical gear ring 20 and the sieve pipe 7 to rotate.

[0018] Specifically, as shown in the figure, the bottom of the box body 1 of this embodiment is provided with a through slot 30, and the material receiving box 5 is slidably mounted in the through slot 30. A partition 31 is fixed on the material receiving box 5, and a mounting plate 32 is fixed on one side of the material receiving box 5. The mounting plate 32 can close the through slot 30. A fixing plate 33 is rotatably mounted on the box body 1, and a connecting rod is fixed on the box body 1. The connecting rod is rotatably mounted on the fixing plate 33 through a bearing, and one side of the fixing plate 33 abuts and engages with one side of the mounting plate 32. The partition 31 divides the material receiving box 5 into two chambers. The left chamber is used to receive impurities such as sand and gravel that fall from the screen tube 7, and the right chamber is used to receive larger shavings that are not easily blown away by the wind. The fixing plate 33 can limit the movement of the mounting plate 32. The mounting plate 32 can close the through slot 30 to prevent sand and gravel in the box body 1 from splashing out of the box body 1. Pulling the material receiving box 5 through the mounting plate 32 is more convenient and labor-saving.

[0019] Furthermore, as shown in the figure, the mounting plate 32 of this embodiment has a curved surface on one side where it contacts the fixing plate 33. When the mounting plate 32 is not completely against the housing 1, when the fixing plate 33 is rotated to limit the mounting plate 32, the sliding contact between the fixing plate 33 and the curved surface can drive the mounting plate 32 to continue to move to the right, completely closing the through-groove 30 for easier use.

[0020] Furthermore, as shown in the figure, the feed pipe 4 of this embodiment is connected to a coaxial conical funnel 50, and a second motor 51 is fixedly mounted on the funnel 50. The second motor 51 is fixedly mounted on the funnel 50 via a plurality of first connecting rods. The rotating shaft of the second motor 51 is fixedly connected to a coaxial rotating shaft 52. The rotating shaft 52 is rotatably mounted on the first connecting rod via a bearing. The outer periphery of the rotating shaft 52 is fixedly connected to the inner periphery of the bearing. The outer periphery of the bearing is fixedly mounted on the first connecting rod via a second connecting rod. The outer periphery of the rotating shaft 52 is fixedly provided with a spiral blade 53. The outer periphery of the spiral blade 53 can be in sliding contact with the inner wall of the funnel 50 and the feed pipe 4. By driving the rotating shaft of the second motor 51 to rotate, the rotating shaft 52 and the spiral blade 53 can be driven to rotate, thereby facilitating the delivery of wood shavings into the feed pipe 4.

[0021] Furthermore, as shown in the figure, the inner side of the discharge pipe 3 of this embodiment is connected with a tapered pipe 60, and the end of the tapered pipe 60 with a small diameter is fixedly mounted on the box body 1. The installation of the tapered pipe 60 makes it easier for small-sized shavings to enter the discharge pipe 3.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
