[0041] In the prior art, wood floating on the flotation liquid is often collected by manual salvage, which has the problems of low mechanization, high cost and low efficiency. Therefore, how to improve the mechanization degree of material flotation equipment, reduce costs and improve efficiency has become a technical problem that needs to be solved urgently.

[0042] In view of this, the utility model provides a flotation device for a flaker material to improve the mechanization degree of the flotation device, reduce costs, and improve the efficiency of flotation of wood.

[0043] Figure 1 is a side view of a flaker material flotation device according to an exemplary embodiment of the present invention.

[0044] According to the utility model, a material flotation device for a flaker is provided. Figure 1 As shown, it includes: a flotation mechanism 10, which is suitable for containing flotation liquid, and wood composed of wood chips processed by a shaving machine 50 enters the flotation mechanism 10 through a feed port, and the flotation liquid is suitable for making the wood float in the flotation liquid, so that the impurities mixed in the wood are deposited at the bottom of the flotation mechanism 10. A liquid diverting mechanism 20, which is rotatably installed above the flotation mechanism 10 through a support frame (not shown in the figure), is suitable for diverting the flotation liquid in a specified direction, so that the wood floating in the flotation liquid moves in the specified direction. A slag discharge mechanism 30, at least a part of which is arranged at the bottom of the flotation mechanism 10, is suitable for transporting at least a part of the impurities deposited at the bottom of the flotation mechanism 10 out of the flotation mechanism 10. And a material transporting mechanism 40, which is arranged downstream of the flotation mechanism 10 in the moving direction of the wood in the flotation mechanism 10, and includes a feeding trough 41 connected to the fluid of the flotation mechanism 10 to receive the wood from the flotation mechanism 10.

[0045] According to the above-mentioned arrangement, the flotation liquid contained in the flotation mechanism 10 separates the wood from the impurities mixed in the wood, so that the wood floats on the flotation liquid and is deposited at the bottom of the flotation mechanism 10. The impurities deposited at the bottom of the flotation mechanism 10 are transported out of the flotation mechanism 10 through the slag discharge mechanism 30. The liquid diverting mechanism 20 diverts the flotation liquid in the direction of the feeding mechanism 40, so that the wood floating on the flotation liquid moves with the flotation liquid, and the wood enters the transport mechanism 40 through the feeding trough 41 with the flotation liquid, and the wood is transported out of the material flotation device of the chipper through the transport mechanism 40, so that the wood is further dried, processed, etc.

[0046] In an illustrative embodiment, the feed trough 41 includes a screen and a lifting baffle. After the wood enters the feed trough 41 along with the flotation liquid and reaches a predetermined amount, the lifting baffle is raised to discharge the flotation liquid in the feed trough 41. The wood remains in the feed trough 41 under the action of the screen. After the flotation liquid is discharged, the screen is opened to allow the wood to enter the material transport mechanism 40.

[0047] According to the above-mentioned arrangement, the feed trough 41 can collect as much wood as possible and transport it to the transport mechanism 40, thereby solving the problem of the wood in the transport mechanism 40 floating back to the flotation mechanism 10 along with the flotation liquid. Moreover, the operation of extracting the wood after flotation in the feed trough does not affect the flotation operation of the wood inside the flotation mechanism, thereby improving the efficiency of wood collection and flotation efficiency.

[0048] Figure 2 It is a front view of a liquid transfer wheel of a flaker material flotation device according to an exemplary embodiment of the utility model.

[0049] In an illustrative embodiment, Figure 1 and Figure 2 As shown, the liquid-displacing mechanism 20 includes at least one liquid-displacing wheel 21, each of which includes: a cylinder portion rotatably mounted above the flotation mechanism 10 through a mounting frame (not shown in the figure); a driving portion, suitable for driving the cylinder portion to rotate; and a plurality of teeth 22, which are arranged on the surface of the cylinder portion and are suitable for displacing the flotation liquid.

[0050] In an illustrative embodiment, Figure 2 As shown, the shifting tooth 22 includes inserting pieces 23, and the inserting pieces 23 are inserted into the barrel portion in an array.

[0051] According to the above arrangement, the inserting piece 23 can be driven to rotate by the cylinder to stir the flotation liquid, so that the flotation liquid drives the wood to flow toward the feeding part 40 .

[0052] In an illustrative embodiment, the liquid diverting mechanism 20 further includes a lifting portion (not shown in the figure) adapted to control the depth of the liquid diverting mechanism immersed in the flotation liquid.

[0053] According to the above arrangement, the liquid diverting mechanism 20 can be moved downward or upward by the lifting part, so as to control the contact area between the insert 23 of the liquid diverting mechanism 20 and the flotation liquid, so as to control the flow speed of the flotation liquid to the feeding mechanism 40 under the action of the liquid diverting mechanism.

[0054] In an illustrative embodiment, the material transport mechanism 40 further includes a screw conveyor, a roller feeder or a belt conveyor extending into the feeding trough.

[0055] In an illustrative embodiment, the material transport mechanism 40 further includes: a liquid collecting tank 42, disposed at the bottom of the material transport mechanism 40, suitable for collecting the flotation liquid carried by the wood; and a liquid discharge port (not shown in the figure), disposed at the bottom of the liquid collecting tank 42, to discharge the flotation liquid contained in the liquid collecting tank 42.

[0056] According to the above-mentioned arrangement, the flotation liquid carried by the wood can flow into the collecting tank 42 along the material transport mechanism 40, and the flotation liquid collected in the collecting tank 42 can be discharged from the material transport mechanism 40 through the discharge port arranged at the bottom of the collecting tank 42, so that the flotation liquid can be discharged from the material transport mechanism 40 in time, thereby reducing the contact time between the wood in the material transport mechanism 40 and the flotation liquid, so as to facilitate the drying and other related treatments of the wood after flotation.

[0057] In an exemplary embodiment, the liquid discharge port is connected to the flotation mechanism and is suitable for recovering at least a portion of the flotation liquid to the flotation mechanism 10 .

[0058] In an illustrative embodiment, Figure 1 As shown, the slag discharge mechanism includes a belt conveyor, which includes: a horizontal part immersed in the bottom of the flotation mechanism and configured to collect impurities deposited from the flotation liquid; and an inclined part, which extends obliquely from one end of the horizontal part out of the flotation mechanism to transport the impurities on the horizontal part to the outside of the flotation mechanism.

[0059] According to the above-mentioned setting method, the horizontal part is set at the bottom of the flotation mechanism, and the impurities mixed in the wood are deposited on the horizontal part under the action of the flotation liquid, and then transported to the inclined part through the horizontal part. One end of the inclined part extends out of the flotation mechanism 10, and the impurities are transported out of the flotation mechanism 10 through the inclined part.

[0060] In an illustrative embodiment, Figure 1 As shown, the belt conveyor includes: a driving wheel 31, which is rotatably mounted above the flotation mechanism 10; a driven wheel 32, which is rotatably mounted at the bottom of the flotation mechanism 10; two guide wheels 33, which are rotatably mounted in the flotation mechanism 10; and a conveyor belt 34, which is movably surrounded by the driving wheel 31 and the driven wheel 32, and bypasses the guide wheels 33, so that the portion of the conveyor belt 34 located between the guide wheels 33 and the driven wheel 32 forms a horizontal portion, and the portion located between the guide wheels 33 and the driving wheel 31 forms an inclined portion.

[0061] Figure 3 is a top view of a belt conveyor of a flaker material flotation device according to an exemplary embodiment of the present utility model.

[0062] In an illustrative embodiment, Figure 3 As shown, the belt conveyor further includes a plurality of baffles 35, which are installed on the conveyor belt 34 perpendicular to the conveyor belt 34 and the moving direction of the conveyor belt, and are arranged at intervals along the moving direction of the conveyor belt to prevent impurities located on the inclined portion from sliding downward.

[0063] According to the above-mentioned setting mode, through the partition of the baffle, on the one hand, the baffle can prevent the impurities from sliding down, and the baffle can also help control the conveying speed of the impurities on the belt, especially in the inclined part, even if the impurities slide due to the excessive speed of the conveyor belt or the excessive slope, they can move with the conveyor belt at a fixed speed under the action of the baffle, ensuring the efficiency of slag discharge. On the other hand, the impurities can be evenly distributed on the conveyor belt, which can avoid excessive accumulation of impurities in a certain section of the conveyor belt, so as to prevent the impurities from overflowing perpendicular to the moving direction of the conveyor belt.

[0064] In an illustrative embodiment, the conveyor belt 34 is further provided with protrusions 36 in an array to increase the friction between the debris and the conveyor belt 34 .

[0065] Based on the above technical solution, the material flotation device of the flaker of the utility model can at least achieve the beneficial effect of improving the collection efficiency of wood.
