Description

Technical Field

[0001] The invention relates to the field of air separation equipment, and in particular to an upward-blowing air separation machine. Background Art

[0002] As we all know, when picking tea leaves, tea farmers cannot accurately pick only the buds on the tea trees, and usually pick them together with the old leaves. Therefore, in the process of making tea, the green tea leaves need to be winnowed, and the finished products rolled into strips by the buds are selected for the next tea making process, and the unfinished products formed by the old leaves are screened out to avoid affecting the taste of the tea. The traditional way of screening is to manually screen them on a dustpan, which has very low screening efficiency and unstable screening quality. For this reason, there are air separators for tea screening on the market. The principle is to use the wind blown by the fan to screen the tea raw materials, which is what tea merchants call air selection. With the research of technology, tea merchants have developed air separators with different structures to improve the quality of air selection. However, no matter which structure of the air separator, the fan is side-blowing, that is, the material is directly discharged downward, the fan on the left or right side blows directly to the material, and the air outlet is correspondingly on the right or left side. The air selection is carried out by direct blowing. For example, the tea air separator disclosed in China Utility Model CN2018204712437 sets the fan on the left side of the machine base, the air outlet is set on the right side of the machine base, and the discharge port is set at the bottom of the machine base. The fan and the air outlet are set opposite to each other. In this way, the non-finished products in the material are blown out through the air outlet, and the finished products fall directly to the discharge port for output. This air separator, because the fan and the air outlet blow directly against each other, it is very easy to blow the finished product out from the air outlet, and the screening quality is not ideal, and multiple screening operations are required.

[0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. Summary of the invention

[0015] The upward-blowing air separator of the present invention: when in use, the material is sent to the upper channel through the feeding mechanism. Because the fan is in the lower channel and blows upward, the material has an upward wind force when in the upper channel. Since the leaves of the old leaves cannot be rolled into a strip-like structure and have a larger wind receiving surface, the upward wind force will blow the unfinished products upward to generate buoyancy, and drift along the wind channel to the transverse wind channel. The wind force at the second end of the transverse wind channel is smaller. At this time, the unfinished products fall downward due to their own gravity due to the reduced wind force and are discharged from the waste material outlet. The bud-shaped tea leaves are rolled into strips with a smaller wind receiving surface and cannot generate upward buoyancy. They will be discharged due to their own gravity. That is, it always falls downward and is guided by the ventilation plate to be output through the discharge port; compared with the prior art, the wind force is downward blowing, and the air outlet is vertically arranged to the wind direction of the fan, and the non-counter-blowing method avoids the finished products from being blown away directly to the waste products, thereby ensuring the screening quality and eliminating the need for multiple screenings.

In addition, the entire structure is simple and easy to process and form. BRIEF DESCRIPTION OF THE DRAWINGS

A through opening 121 communicating with the horizontal channel is provided on the left side wall of the upper frame 12, and this through opening 121 is the air outlet.

[0022] A partition plate 2 is fixedly provided in the vertical channel, which is inclined downward and divides the vertical channel into an upper channel and a lower channel. This partition plate 2 is a ventilation plate, and a through hole is opened at the lower end of the lower channel for exposing the lower end of the partition plate 2 and leading to the outside of the machine base, and this through hole is the discharge port; specifically, the partition plate 2 is a metal plate body, and the partition plate 2 is inclined downward from right to left, and the second partition plate 112 is upright and located below the upper end of the partition plate 2 and fixedly connected to the partition plate 2, and the portion of the partition plate 2 located below the upper end of the second partition plate 112 is a naked structure, that is, the partition plate 2 is provided with a square opening 21 below the portion where the second partition plate 112 is connected to the partition plate 2, and the square opening 21 extends to the lower end of the first partition plate and is located on the right side of the first partition plate, and the lower end of the first partition plate 111 is recessed upward with a strip opening extending in the front-to-back direction, that is, the first partition There is a spacing of 100 between the lower end of the partition and the lower end of the partition plate 2, and a strip opening which is connected to the spacing 100 and extends in the front-to-back direction is provided on the bottom left wall of the seat body 111, and this strip opening is the discharge port; and a ventilation mesh (not shown in the figure) is installed on the metal plate body in the bare area, the fan is at the lower end of the lower channel, and the air outlet of the fan is arranged upward, that is, a circular opening 12 is provided on the bottom surface of the seat body 11 located at the lower channel, the fan is flatly installed on the lower bottom surface of the seat body 11 and is in the circular opening 12, and the air outlet surface of the fan is arranged upward, so that the wind blown out by the fan can pass through the mesh holes of the ventilation mesh and flow upward, and the ventilation mesh can be used to block the material to prevent the material from falling into the fan, and the inclination of the partition plate 2 can be used to guide the material to be discharged, and it is also convenient to connect with the output end of the feeding device.

[0023] The output end of the feeding mechanism is connected with the upper part of the upper channel, and the output end of the feeding mechanism is arranged on two opposite sides of the discharge port. Specifically, the feeding mechanism is installed in the third chamber, and the feeding mechanism has a feeding belt 3 and a driving motor (not shown in the figure). The feeding belt 3 is arranged to be inclined upward, and the upper end of the feeding belt 3 is on the left side. The feeding belt 3 is wound around an upper rotating shaft (not shown in the figure) and a lower rotating shaft (not shown in the figure). The upper rotating shaft and the lower rotating shaft are both arranged horizontally along the front and rear directions of the machine base and rotatably installed on the machine base. The driving motor is installed outside the lower right part of the base body, and drives the lower rotating shaft to rotate, that is, the output shaft of the driving motor is directly connected to one end of the lower rotating shaft, or is connected through a transmission chain. The upper end of the feeding belt 3 is below the left side of the upper cavity opening of the third chamber, and there is a feeding distance between the upper cavity opening of the third chamber, that is, the upper end of the feeding belt 3 is below the top surface of the base body 11, and the upper end of the feeding belt 3 is connected and matched with the upper end of the ventilation plate. In the present invention, the feeding mechanism is a conventional material conveying device, which will not be described here. When used, the material is poured into the third chamber, the driving motor is started, and the feeding belt 3 moves in a closed loop. The rotation of the feeding belt 3 can convey the material in the third chamber upward to the feeding distance. Finally, the material falls downward into the partition plate 2 due to its own gravity, and slides downward due to the inclination of the partition plate 2.

[0024] The inner cavity wall of the upper channel located on the same side as the transverse channel is provided with a body adjustment structure for the material to collide with, and after the collision, the body shape of the material is adjusted to make the material in a straight state, that is, the body adjustment structure is provided on the left inner cavity wall of the upper channel. Specifically, a plurality of strip convex strips 1111 along the front and rear directions are convexly provided on the right side surface of the first partition plate 111, and the front and rear ends of each strip convex strip 1111 are in contact with the front inner cavity wall and the rear inner cavity wall of the second chamber, and each strip convex strip 1111 is in contact with the front inner cavity wall and the rear inner cavity wall of the second chamber. The top and bottom surfaces of the convex strips 1111 are both inclined surfaces, and the strip convex strips 1111 are in an isosceles triangle structure that gradually shrinks from left to right. The strip convex strips 1111 are arranged continuously from top to bottom, and in two adjacent strip convex strips 1111, the right tip of the next strip convex strip is on the right side of the right tip of the previous strip convex strip, that is, the width of each strip convex strip in the left-right direction gradually expands from top to bottom, and the next strip convex strip protrudes out of the previous strip convex strip, and each strip convex strip constitutes the posture adjustment structure. When in use, since the contact surface of the unfinished product is large, if its body turns over and becomes non-straight during the rising process, the wind-receiving surface of the unfinished product will be reduced. Therefore, when the unfinished product approaches the top of the second chamber, it will fall freely due to the small wind force and the small wind-receiving surface, and will hit the top surface of the strip convex strip 1111 when it falls. At this time, the top surface of the strip convex strip 1111 is inclined downward to the right, so that the unfinished product slides down and fits with the strip convex strip 1111 to adjust its body shape. When it slides down to the tip of the strip convex strip 1111, it becomes straight under the influence of the upward wind force, so that the unfinished product continues to float upward to generate buoyancy; at the same time, the strip convex strips are arranged with downward convex strips in sequence, so that the unfinished product can slide down along the strip convex strips in sequence to the bottom of the strip convex strip, so that the unfinished product can be quickly adjusted under the influence of the strong wind when it is at the bottom, and can quickly float upward to the horizontal channel.

[0025] The bottom of the transverse channel is provided with a waste channel arranged downwardly, a side opening communicating with the second end of the transverse channel is provided on the machine base, and the side opening is the air outlet, and a waste opening communicating with the waste channel is provided at the machine base below the air outlet; specifically, the waste channel is provided at the first chamber, and a downwardly inclined guide plate 4 is fixed in the first chamber, and the space above the inclined guide plate in the first chamber is the waste channel, and the upper end of the inclined guide plate 4 is in close contact with the top rear inner cavity wall of the first chamber, and the lower end of the inclined guide plate 4 is in close contact with the bottom front inner cavity wall of the first chamber, and a strip through hole communicating with the first chamber is provided on the front side wall of the seat body 11 at the lower end of the inclined guide plate 4, and the strip through hole is the waste opening. When in use, when the material floats to the first chamber, due to the small wind force, the material falls downward under its own gravity, and slides down along the inclined guide plate 4 to the waste opening for output. In the present invention, the inclined guide plate 4 can also be inclined backward, that is, the upper end of the inclined guide plate is close to the top front inner cavity wall of the first chamber, and the lower end is close to the bottom rear inner cavity wall of the first chamber, and the waste port is opened on the rear side wall of the seat body.

[0026] The upward-blowing air separator of the present invention: when in use, the material is poured into the third chamber, the driving motor is started, the material is transported upward to the second chamber through the feeding belt 3, and slides downward along the partition plate 2. When sliding downward, the finished products in the material are in the shape of thin strips with a small wind receiving area and will not be blown upward by the wind. The unfinished products are in the shape of wide flat strips with a large wind receiving area and will generate buoyancy due to the upward wind and float upward. At this time, the finished products continue to slide downward due to the inclination of the partition plate 2 and are output through the discharge port, and the unfinished products float upward due to the upward wind. The unfinished products floating upward float with the wind direction and into the transverse channel and into the first chamber of the transverse channel. Because the first chamber is separated from the second chamber and the wind force is small, the unfinished products sink due to the small wind force and their own large gravity. The unfinished products fall onto the inclined guide plate 4 of the first chamber, slide downward along the inclined guide plate 4, slide out of the seat body 1 through the waste material port for recovery.

[0027] Compared with the prior art, the upward-blowing air separator of the present invention utilizes the upward-blowing wind to generate buoyancy for the unfinished products, while the finished products will not generate buoyancy and will always slide down for screening. In addition, the air outlet is arranged vertically to the wind direction of the fan, and the non-opposite blowing method is adopted. Thus, if the finished products are blown upward to a certain height by the wind, the buoyancy of the finished products is small due to the small wind receiving area, and it is difficult for the finished products to flow into the first chamber with the wind flow, but will fall freely, and the finished products poured freely will slide down to the bottom of the partition plate 2 under the guidance of the strip convex strips, and finally will be discharged from the discharge port. The unfinished products are output from the outlet, which avoids the finished products being blown away directly to the waste products, ensures the screening quality, and does not need multiple screening; at the same time, if the unfinished products are turned over during the rising process, they will fall down like the finished products, and adjust their posture through the inclined surface of the strip convex strips to make the unfinished products in a straight state. At this time, the wind can blow the unfinished products upward to the first chamber, thereby ensuring that the unfinished products can be in a straight state when they are in the upper part of the upper channel and be blown to the first chamber for recovery by the upward wind force, and the screening effect is better; in addition, the whole structure is simple and easy to process and shape.

[0028] In the present invention, a guide plate 22 is integrally extended from the lower end of the metal plate body and extends out of the seat body through the discharge port, that is, the guide plate 22 extends out of the seat body 11 through the discharge port, which facilitates the output of the finished product. Furthermore, a guide plate (not shown in the figure) extending out of the waste port may also be integrally extended from the lower end of the inclined guide plate 4.

[0029] In the present invention, a plurality of strip-shaped protrusions (not shown in the figure) extending in the left-right direction are arranged on the front inner side wall of the upper channel, the top and bottom surfaces of each strip-shaped protrusion are inclined surfaces, and the strip-shaped protrusions are in an isosceles triangle structure which gradually shrinks from front to back, and in two adjacent strip-shaped protrusions above and below, the rear tip of the upper strip-shaped protrusion is located on the rear side of the rear tip of the upper strip-shaped protrusion; the strip-shaped protrusions can also be used to perform certain body adjustments on the materials, because the materials rarely collide with the front inner wall of the first chamber, and in order to avoid wind being blocked, the width of the strip-shaped protrusions should not be gradually expanded from bottom to top.

[0030] In the present invention, an air flow outlet 122 extending in the front-to-back direction is provided on the top surface of the upper frame 12 within the range of the vertical channel, and a push-pull plate (not shown in the figure) for adjusting the conduction amount of the air flow outlet is installed at the air flow outlet 122 of the upper frame 12. The air flow outlet 122 can be used to adjust the airflow in the airway to prevent wind turbulence blowing upward.

[0031] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
