The following describes a separation device provided by the present application in detail with reference to the accompanying drawings and embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a separation device according to a first embodiment of the present application.

As shown in fig. 1, in the present embodiment, the separator 100 includes a feeder 11, a discharger 12, and a rebounding device 13.

The feeding device 11 includes a feeding end 111 and a discharging end 112 respectively located at two ends. The blanking device 12 includes a feeding port 121 and a discharging port 122, the feeding port 121 is located below the blanking end 112, and the blanking device 12 is inclined with respect to the horizontal direction so that the material falling from the blanking end 112 moves along the inner side surface of the blanking device 12. The rebounding device 13 is connected with the discharge hole 122 and is inclined relative to the horizontal direction, and the inclination angle of the rebounding device 13 relative to the horizontal direction is smaller than that of the blanking device 12 relative to the horizontal direction, so that different materials slide for different distances when leaving the rebounding device 13 according to the physical properties of the materials and fall into different positions.

The rebounding device 13 is detachably connected to the discharge hole 122, and the rebounding device 13 can adjust the inclination angle of the rebounding device relative to the horizontal direction.

The feeding device 11 is a conveyor belt moving from a feeding end 111 to a discharging end 112, and the feeding end 111 is lower than the discharging end 112.

In this embodiment, the material to be sorted by the separation apparatus 100 is short wood produced during stacking, handling, slicing, etc. of raw wood in the manufacture of paper, and the short wood is mixed with a large amount of bark. The utility model discloses the sorting principle is according to the quarter log and the bark when dropping from the eminence through leading to the groove, has different movement tracks behind the striking baffle and divides the quarter log in the bark, sets up loading attachment 11 and transports the eminence from the low in order to wait to sort the material, and in concrete operation process, the material loading end 111 at loading attachment 11 is placed with the material to the manual work, and loading attachment 11 can carry the unloading end 112 of material to the eminence.

In a preferred embodiment, the feeding device 11 is a movably arranged conveyor belt. Specifically, the feeding device 11 can be adjusted according to actual needs. In this application, loading attachment 11 chooses for use the conveyer belt, and it is higher to carry material efficiency, and it is lower to be difficult to damage the cost. In other embodiments, the feeding device 11 may also be a lifting arm with a lifting function, and the like, which is not specifically limited in this application.

In this embodiment, after the loading device 11 transports the material from the loading end 111 to the high unloading end 112, the material drops into the feeding hole 121 at the unloading end 112 and passes through the unloading device 12. The blanking device 12 has a larger inclination angle, the falling body movement is similar to that of the continuous acceleration of the material in the process of passing through the blanking device 12, when the material falls to the location of the discharge opening 122, the short wood and the bark in the material have different speeds. The short wood has a high moving speed, the barks slide in a sticking way with the blanking device 12 due to physical characteristics when falling in the blanking device 12, the resistance is high during the moving process, and the moving speed is low when the barks reach the position of the discharge hole 122. When short wood and bark with different speeds collide with the rebounding device 13 with a smaller inclination angle relative to the horizontal direction than the blanking device 12, the speed of the short wood in the material after colliding with the rebounding device 13 is higher in the horizontal direction, and the speed of the bark in the material after colliding with the rebounding device 13 is lower in the horizontal direction. The short wood and the bark have different speeds after colliding with the rebounding device 13, the moving tracks of the short wood and the bark in the air are different, the short wood and the bark fall at different positions, and based on the above, the separating device 100 can realize the separation of the short wood from the material.

In other embodiments, the rebounding means 13 may also be an elastic plastic plate with high toughness, and the application is not limited in this regard.

With reference to fig. 2, fig. 2 is a schematic structural diagram of a second embodiment of the separation apparatus of the present application.

As shown in fig. 2, in the present embodiment, the separating device 200 further includes a guide groove 24 and a collecting tank 25 in addition to the feeding device 21, the discharging device 22, and the rebounding device 23.

The feeding device 21 includes a feeding end 211 and a discharging end 212 respectively located at two ends. The discharging device 22 comprises a feeding hole 221 and a discharging hole 222, the feeding hole 221 is positioned below the discharging end 212, and the discharging device 22 is inclined relative to the horizontal direction so that the material falling from the discharging end 212 moves along the inner side surface of the discharging device 22. The rebounding device 23 is connected with the discharge port 222 and is inclined relative to the horizontal direction, and the inclination angle of the rebounding device 23 relative to the horizontal direction is smaller than that of the blanking device 22 relative to the horizontal direction, so that different materials slide different distances when leaving the rebounding device 23 according to the physical properties of the materials and fall into different positions.

The guide groove 24 is located below the rebounding device 23 and spaced from the rebounding device 23, and a gap exists between the guide groove 24 and the rebounding device 23 in vertical projection.

Wherein, the collecting box 25 is arranged corresponding to the rebounding device 23 and the guide groove 24 and is used for collecting the falling materials in a preset range.

In the present embodiment, the guide groove 24 is provided to further guide the short log to fall to the designated area. The short wood and the bark have different motion tracks after being collided with the rebounding device 23, the guide groove 24 is arranged corresponding to the motion track of the short wood, after the short wood is collided with the rebounding device 23, the short wood has a high motion speed in the horizontal direction and can fall onto the guide groove 24, and after falling onto the guide groove 24, the short wood can slide along the groove body and finally fall into a designated area. After the bark collides with the rebounding device 23, the bark has a relatively low moving speed in the horizontal direction and falls into the gap between the guide groove 24 and the rebounding device 23.

In this embodiment, there are preferably two collection boxes 25, one collection box 25 being placed below the rear end of the guide groove 24 for temporarily storing the sorted logs. A collecting box 25 is placed below the gap between the guide groove 24 and the rebounding device 23 for temporarily storing the bark.

The discharging device 22 is a through slot provided with a bottom plate (not shown) which is located below the discharging end 212 and is inclined relative to the horizontal direction, so that the material falling from the discharging end 212 moves along the surface of the bottom plate.

The bottom plate is detachably connected with the blanking device 22, and the bottom plates with different friction coefficients can be replaced according to requirements.

In the present embodiment, the short wood and bark pass through the blanking device 22, specifically, pass through the bottom plate provided on the blanking device 22 in a sliding manner. When the short wood passes through the blanking device 22, the friction resistance of the bottom plate to the short wood is small, and when the short wood slides to the discharge hole 222, the short wood has a high speed. The friction resistance of the bottom plate against the bark is greater when the bark passes through the blanking device 22 and the speed is lower when the bark slides to the discharge opening 222. The bottom plates with different friction coefficients can be replaced according to requirements, so that the friction resistance of the blanking device 22 to the short wood and the barks can be adjusted, and the falling speed and the subsequent movement track of the short wood and the barks from the discharge hole 222 can be correspondingly changed.

The inclination angle of the rebounding device 23 with respect to the horizontal direction is smaller than that of the blanking device 22 and larger than that of the guide groove 24. The guide groove 24 is inclined with respect to the horizontal direction, and the angle at which the guide groove 24 is inclined with respect to the horizontal direction is smaller than the angle at which the blanking device 22 is inclined with respect to the horizontal direction. The angle of inclination of the blanking device 22 with respect to the horizontal direction is 65 to 80 degrees, and the angle of inclination of the guide groove 24 with respect to the horizontal direction is 35 to 45 degrees.

It will be appreciated that the angle of inclination of the blanking unit 22 is relatively large in order to allow the log to move in a free fall-like manner as it passes through the blanking unit 22, and to allow the log to reach the discharge outlet 222 at a relatively high speed. Meanwhile, the inclination angle of the blanking device 22 cannot be so high that the material passes through the blanking device 22, the blanking device is separated from the bottom plate, the friction force of the bottom plate to the material is eliminated, the bark and the bottom plate need to be guaranteed to slide in a sticking manner and bear large friction force, and meanwhile, the friction force between the short wood and the bottom plate, which has physical characteristic difference with the bark, is far smaller than the friction force between the bark and the bottom plate, so that the bark and the bottom plate have large speed difference when reaching the discharge port 222.

It is understood that the angle of inclination of the rebounding device 23 with respect to the horizontal is only smaller than the angle of inclination of the blanking device 22 with respect to the horizontal. The material can impact on the rebounding device 23 after falling out of the material outlet 222, so that different movement tracks of the short wood and the bark can be realized.

In the present embodiment, the blanking device 22 is inclined at an angle of 70 degrees with respect to the horizontal direction, and the guide groove 24 is inclined at an angle of 40 degrees with respect to the horizontal direction. In other embodiments, the angle of inclination of the blanking device 22 with respect to the horizontal is 65 degrees at the lowest and 80 degrees at the highest. The guide groove 24 is inclined at an angle of 35 degrees at the lowest and 45 degrees at the highest with respect to the horizontal direction. This is not a particular limitation of the present application.

As shown in table 1, table 1 is a statistical table of the recycled amount of short woods from the company 2020 year after the separation device 200 of the present application is put into use in 1 month 2020 year, and it can be seen from the statistical table that the effect is remarkable and the recycled amount of short woods is large after the separation device 200 is put into use, and the recycling cost of the separation device 200 is almost 0 during use, so that a large amount of raw material cost is saved for the company, and the concept of green cycle paper making is practiced.
