The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in combination with specific cases.

The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The embodiment relates to a material winnowing device, which is used for separating light materials from heavy materials in materials.

In the whole structure, as shown in combination with fig. 1, the material winnowing device of this embodiment includes a box 1, an air suction pipe 2, an air suction fan 3 and a discharge pipe 4.

Wherein, the top of box 1 is equipped with feed inlet 11, and the right side of box 1 extends outward to box 1, forms from left to right diameter dwindle induced draft mouth of pipe 21 gradually, and aspiration channel 2 and induced draft mouth of pipe 21 intercommunication to be equipped with suction fan 3 in the tip of aspiration channel 2. The bottom wall 12 of the case 1 is arranged obliquely downward from the right side to the left side wall 13, and the end of the bottom wall 12 is provided with a right pipe wall 14 arranged downward. The bottom of the left side wall 13 is formed with a guide plate 15 arranged obliquely downward to the right, and a left pipe wall 41 arranged downward is connected to the guide plate 15. The right tube wall 14 and the left tube wall 41 enclose the discharge tube 4.

Through the arrangement of the suction fan 3, air flows enter the box body 1 through the discharging pipeline 4 to carry out air separation on materials, and light materials are discharged through the suction pipe 2, so that the separation effect and separation efficiency are improved, and the efficient production requirement can be met.

Based on the above overall description, specifically, the housing 1 of the present embodiment is provided with a frame, and when the device is used, the device is horizontally placed on the ground or mounted on other related devices through the frame. The unsorted materials enter the box body 1 through the feeding hole 11 for winnowing and are discharged through the discharging pipeline 4, meanwhile, the right pipe wall 14 is of a U-shaped structure, and the left pipe wall 41 and the right pipe wall 14 can be formed into the discharging pipeline 4 in a surrounding mode.

It will be appreciated that when the material falls from the inlet 11 to the bottom wall 12 or the guide plate 15, the falling light material can be blown by the air flow, and the light material is sucked into the air suction pipe 2 and discharged through the air suction fan 3, and the heavier material is discharged from the discharge pipeline due to the fact that the gravity is greater than the lifting force of the air flow, so that the light material can be effectively separated.

When the material moves along the bottom wall 12 and the guide plate 15 to the pipe mouth of the discharging pipe 4, as the top end of the right pipe wall 15 is higher than the top end of the left pipe wall 41, the left pipe wall and the right pipe wall can form a certain drop, the air flow rising from the discharging pipe 4 can be relatively weakened when reaching the left pipe wall drop and the right pipe wall drop, when the slightly heavy material which is not completely separated in the discharging pipe 4 is re-sucked to the left pipe wall drop and the right pipe wall drop, the air flow is weakened, the slightly heavy material blocked by the right pipe wall 14 can fall into the discharging pipe 4 again and move downwards, the light material is prevented from being blown up into the air suction pipe 2 by the air flow, the light material is easier to be blown up by the air flow entering through the discharging pipe 4 and separated from the slightly heavy material, and then the light material is continuously conveyed into the air suction pipe 2 by the air flow and finally discharged by the suction fan 3, and further the effective separation of the materials with the small weight difference can be realized.

So wait the material of sorting in the material wind selector of this embodiment, experienced the selection by winnowing of twice air current, through the process of above-mentioned selection by winnowing separation, can improve separation effect and separation efficiency, and diapire 12 and deflector 15 contained angle's setting can be favorable to the material that the separation weight is more close to a certain extent.

In particular, the case 1, the cover plate, the guide plate 15 and the feed pipe may preferably be made of stainless steel plates and formed by welding, which ensures the structural strength of the device and improves the durability. Meanwhile, the centrifugal fan can be preferably adopted by the suction fan 3, and the light material can be discharged through the inside of the fan. In addition, when the material is lighter, if the suction force of the suction fan 3 is larger, the material can be sucked into the suction pipe 2, so that the suction fan 3 can preferably adopt a variable frequency fan to adjust the wind power according to the actual working condition.

As a preferred implementation manner, the top end of the left pipe wall 41 in this embodiment is provided with a connecting plate 42, and the connecting plate 42 can drive the left pipe wall 41 to move along the guide plate 15, so that the width of the discharge pipe 4 can be changed when the left pipe wall 41 moves, and meanwhile, the guide plate 15 is provided with a locking mechanism 43 for locking the connecting plate 42. The width of the discharging pipeline 4 is changed by moving the left pipe wall 41, so that the air inlet quantity and the air flow speed of the discharging pipeline 4 are adjusted to adapt to materials with different weights, and the sorting effect and the light material removing efficiency are improved.

In practice, the locking mechanism 43 may be a conventional locking mechanism 43 known to those skilled in the art, for example, the locking mechanism 43 may preferably include a slot provided with a bottom of the guide plate 15, and a hand-screwed bolt provided on the slot, and the connecting plate 42 may be abutted on the guide plate 15 by rotating the hand-screwed bolt, thereby locking the position of the left pipe wall 41, or other conventional structure may be used to lock the position of the left pipe wall 41. In addition, in the present embodiment, the connecting plate 42 may be disposed at the top end of the right pipe wall 14, so that the right pipe wall 14 moves along the bottom wall 12, and the width of the discharge pipe 4 is changed, and correspondingly, the bottom wall 12 is provided with a locking mechanism 43 for fixing the connecting plate 42.

In this embodiment, the light material blown by the air flow in the box 1 will enter the air suction pipe 2, so in order to improve the air suction and light material collection efficiency of the air suction pipe 2, an air suction pipe orifice 21 with gradually reduced caliber from left to right is connected between the air suction pipe 2 and the box 1, and the air suction pipe orifice 21 forms a transition between the box 1 and the air suction pipe 2, so that the air flow carrying the light material smoothly enters the air suction pipe 2 from the box 1, and meanwhile, the design of gradually reduced caliber of the air suction pipe orifice 21 improves the air flow velocity in the air suction pipe 2, and further improves the discharge efficiency of the light material. In a specific implementation, the air suction nozzles 21 may be disposed towards different directions outside the box 1, and preferably, the air suction nozzles 21 may extend along the outside of the box 1 in a horizontal direction or extend obliquely upwards towards the outside of the box 1, so that the air flow in the box 1 can carry the light materials to be winnowed and smoothly discharge along the air suction nozzles 21.

It will be appreciated that when the weight difference between the two materials is large, the air flow from the air inlet 16 is able to blow light materials into the air inlet duct to enhance the air separation effect.

Meanwhile, when the weight difference of the two materials is small and the weight of the two materials is light, the air flow entering from the air inlet 16 easily blows all the two materials with different weights into the air suction pipe 2, so that the air door 17 is designed at the air inlet 16, the size of the air inlet 16 can be changed according to the actual condition of the materials, and the air flow speed and the air inlet quantity are adjusted to be more suitable.

In practice, the air door 17 may be of a conventional structure known to those skilled in the art, for example, the air door 17 may preferably include a frame disposed at the air inlet 16, and a baffle rotatably disposed on the frame, where the baffle can change the size of the air inlet 16, or a grid-shaped net opening is disposed at the air inlet 16, and a plug board is disposed for adjusting the size of the air inlet 16, or other structures can be used to adjust the size of the air inlet 16.

It will be appreciated that when the air stream carrying the light material is discharged through the suction fan 3, the light material collides with the blades of the suction fan 3, eventually resulting in a reduction in the service life of the suction fan 3. Therefore, in order to improve the service life of the suction fan 3, as a preferred implementation manner, in conjunction with fig. 2, a saxophone is connected in series to the suction pipe 2 in this embodiment. It comprises a cylinder 22, an inlet 23 provided on one side of the cylinder 22, and an outlet pipe 24 provided on the top of the cylinder 22.

The cylinder 22 comprises a cylinder part and a conical part with gradually reduced caliber from top to bottom, the inlet 23 is arranged on one side of the cylinder part, the inlet 23 is connected with the air suction pipe orifice 21, the outlet pipe 24 is arranged on the top of the cylinder part, and the outlet pipe 24 is connected with the air suction pipe 2. The bottom of the cylinder part is connected with the top of the cone part, the bottom of the cone part is provided with a discharge hole 25, and the discharge hole 25 is provided with a wind-proof discharger.

When the air flow carrying the light materials enters the cylinder 22 of the saxophone, the air flow carrying the light materials rotates in the cylinder 22, the light materials are separated from the air flow by centrifugal force and are trapped on the inner wall of the cylinder 22, the light materials fall to the discharge port 25 by gravity and are discharged through the wind-shielding discharger at the discharge port 25, and the air flow is discharged through the outlet pipe 24 by the air suction pipe 2 and the air suction fan 3. Compared with the mode of discharging the light materials through the suction fan 3, the light materials in the air flow can be separated and collected in a concentrated mode, the damage of the light materials to the suction fan 3 is avoided, and the service life of the suction fan 3 is prolonged.

As a preferred implementation form, the bottom of the bottom wall 12 of the present embodiment is provided with a vibration device, and the vibration device includes an electric motor 121 and an eccentric rotor 122 disposed on a transmission shaft of the electric motor 121, when the electric motor 121 is started, the eccentric rotor 122 can be driven to rotate, and under the action of the eccentric rotor 122, the bottom wall 12 is vibrated to disperse the materials on the bottom wall 12 that are not completely separated, so as to improve the separation effect of the light and heavy materials.

It will be appreciated that the bulk materials sorted by the device are mostly bulk materials with smaller volume, so as a preferred implementation form, the top of the box 1 of the embodiment is provided with the feeding funnel 5, and the feeding funnel 5 is connected with the feeding port 11, so as to facilitate adding materials into the box 1. Meanwhile, the sorting effect is reduced in order to avoid excessive materials or uneven addition of materials in the box body 1 at one time.

Meanwhile, as a preferred implementation form, a wind-proof discharger is arranged between the feeding funnel 5 and the feeding port 11, the wind-proof discharger can prevent the air flow from entering the box body 1 from the feeding port 11 to a certain extent to cause the reduction of the sorting effect, and meanwhile, the wind-proof discharger can also control the feeding of a certain amount of materials into the box body 1 each time.

Specifically, the wind-shielding discharger comprises a shell 51, an impeller 52 arranged in the shell 51 in a rotating manner, the shell 51 is penetrated up and down, when materials enter the shell 51, the materials firstly enter between two blades of the impeller 52, the impeller 52 is pushed to rotate, and the materials between the two blades are discharged from the bottom of the shell 51 into the box 1.

It will be appreciated that when the impeller 52 rotates, the blades divide the material into multiple parts and sequentially feed the material into the housing 1, so as to avoid excessive material entering the housing 1 once, and the speed of rotation of the impeller 52 determines the speed of feeding the material into the housing 1. And, the wind-proof discharging device at the discharging hole 25 can prevent the air flow from the discharging hole 25 to enter the cylinder 22 to a certain extent, so as to avoid the reduction of the sorting effect.

In a specific implementation, the impeller 52 may be driven by a motor, and the impeller 52 is driven to rotate by the motor, or the impeller 52 is driven to rotate by gravity of the material, so that the material can be input into the box 1 at a certain speed.

In this embodiment, as a preferred implementation manner, as shown in fig. 3, a sliding rail 111 is provided at the top of the case 1 in this embodiment, a sliding block 112 is provided in the sliding rail 111, and a feed inlet 11 is provided on the sliding block 112. The slide block 112 can drive the wind-proof discharger and the feeding funnel 5 to move along the slide rail 111. An organ cover 113 is arranged between the sliding block 112 and the sliding rail 111, and the organ cover 113 can seal the top of the box body 1.

Therefore, the feeding hopper 5 and the wind-shielding feeder can move along the sliding rail 111 so as to change the position of the material from the air suction pipe 2 and the position of the material falling on the bottom wall 12 or the guide plate 15 when the material enters the box body 1, and the organ cover 113 can block the top of the box body 1 to a certain extent, so that the wind separation in the box body 1 is not greatly influenced even if a certain wind leakage condition exists.

It will be appreciated that when the mass of material is light and the material is close to the suction duct 2, the heavy and light material is easily sucked all into the suction duct 2, so that the material cannot be effectively air separated. In this case, the hopper 5 and the wind-shielding discharger are moved leftward, and wind separation is performed by the fall between the guide plate 15 and the bottom wall 12. When the weight difference between the heavy and light materials is large, the feeding hopper 5 and the wind-shielding discharger can be moved rightwards to enable the materials to be close to the air suction pipe 2, so that the high air flow speed is utilized for air separation, and the sorting effect of the materials is improved to a certain extent.

In addition, as further shown in fig. 4, as a preferred embodiment, a partition wall 44 is provided between the left wall 41 and the right wall 14, the partition wall 44 can divide the tapping pipe 4 into two parts, and the partition wall 44 and the right wall 14 enclose a secondary tapping pipe 46. The top end of the partition wall 44 is higher than the top end of the left wall 41, and the top end of the partition wall 44 is lower than the top end of the right wall 14. The bottom end of the right pipe wall 14 is hinged with a cover plate 45 for plugging the auxiliary discharging pipe 46, and one end of the cover plate 45 far away from the discharging pipe 4 is connected with a counterweight body. When part of the materials in the discharge pipeline 4 rise along with the airflow, the heavier materials fall into the auxiliary discharge pipe 46 under the action of gravity due to no rising airflow at the auxiliary discharge pipe 46 when passing through the upper end of the partition pipe wall 44, so that the slightly heavier materials in the blown-up light materials are separated again, the winnowing effect is improved, and when the slightly heavier materials are gathered to a certain amount in the auxiliary discharge pipe 46, the slightly heavier materials are discharged by pressing the cover plate 45.
