The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A dust collection processing apparatus 100 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1, a dust collection processing apparatus 100 according to an embodiment of the present invention includes a box 1, a material sliding plate 2, and a material jumping plate 3.

Wherein, the box body 1 is provided with a feed inlet 11 and a dust suction port 12. The material sliding plate 2 is arranged in the box body 1, the material sliding plate 2 is positioned below the feeding hole 11 or is connected with the feeding hole 11, the two opposite ends of the material sliding plate 2 are a material collecting high end 21 and a material collecting low end 22, and the material collecting low end 22 is lower than the material collecting high end 21.

Therefore, the materials enter the box body 1 through the feed inlet 11, and fall onto the material sliding plate 2 after passing through the feed inlet 11. In the example of fig. 1, the feed inlet 11 is located at the top of the box 1, and the chute plate 2 is located below the feed inlet 11, and the material falls onto the chute plate 2 under the action of gravity after passing through the feed inlet 11. In addition, the feed inlet 11 can also be arranged on the side wall of the box body 1, at the moment, the material sliding plate 2 can be connected with the side wall of the box body 1 where the feed inlet 11 is arranged, and materials can directly fall on the material sliding plate 2 after passing through the feed inlet 11.

It can be understood that, since the aggregate low end 22 is lower than the aggregate high end 21, after the material falls on the chute plate 2, the material can slide out of the chute plate 2 from the aggregate high end 21 to the aggregate low end 22 along the chute plate 2 under the action of gravity, and after the material slides out of the chute plate 2 from the aggregate low end 22, the material falls down to the side of the aggregate low end 22 away from the aggregate high end 21.

Meanwhile, the material jumping plate 3 is arranged in the box body 1, the material jumping plate 3 is lower than the material collecting low end 22 of the material sliding plate 2 so that a jumping gap 30 is formed between the material jumping plate 3 and the material sliding plate 2, and at least part of the material jumping plate 3 is positioned on one side of the material collecting low end 22 far away from the material collecting high end 21. The material jumping plate 3 is arranged in the box body 1 and used for receiving materials sliding from the material sliding plate 2, and the materials fall from the material collecting lower end 22 and fall onto the material jumping plate 3 after passing through the jumping gap 30. Because the material jumping plate 3 is lower than the material collecting lower end 22 of the material sliding plate 2, the jumping gap 30 has a certain height, when the material falls from the material collecting lower end 22 to the material jumping plate 3, the material can be dispersed in the jumping gap 30 and fully contacted with air, the material falling on the material jumping plate 3 can be rolled and further dispersed, and light impurities can be dispersed after the material is rolled.

It should be noted that the material-skipping plate 3 is at least partially located on the side of the aggregate low end 22 away from the aggregate high end 21, so that the material-skipping plate 3 can receive most of the material falling from the aggregate low end 22. However, a small amount of materials fall from the aggregate low end 22 and pass through the jumping gap 30, and then continuously fall to the bottom of the box body 1 and do not fall onto the jumping plate 3, the materials in the part can be fully dispersed in the falling process due to the small amount of the materials, and the dispersed materials can be fully contacted with air.

Further, the case 1 has an air suction opening 13, or a blower 14 is provided in the case 1. An air suction opening 13 or a blower 14 is provided for forming an air flow passing through the material and flowing out of the dust suction opening 12 in the case 1.

It can be understood that the weight of the light impurities is much smaller than that of the material particles, and the air flow can drive the light impurities by controlling the flow rate of the air flow, and the movement of the material is less influenced.

From this, the material can scatter and can fully contact with the air current in jump gap 30 to the air current passes the material in jump gap 30 can effectually take out light impurity from the material, makes light impurity leave the material along with the air current. After most of materials fall on the material jumping plate 3, the materials are further scattered on the material jumping plate 3, and light impurities scattered by the materials rolling on the material jumping plate 3 can be taken away by airflow. For the possible materials which are not dropped on the material-jumping plate 3 in a small amount, the materials can be fully dispersed and fully contacted with the airflow in the process of dropping the materials at the bottom of the box body 1 because the amount of the materials is less, so that the airflow can effectively take away light impurities in the materials. After the light impurities are taken away by the air flow in the box body 1, the light impurities are discharged out of the box body 1 through the dust suction port 12 along with the air flow, at the moment, the materials fall to the bottom of the box body 1 under the action of gravity, and finally the separation of the light impurities and the materials is realized.

In the example of fig. 1, a dust suction port 12 of the box body 1 is arranged at the top of the box body 1, the dust suction port 12 is positioned at the same side of the material sliding plate 2 and the material jumping plate 3, an air suction port 13 is arranged on the dust suction port 12, and a blower 14 is arranged in the box body 1, and the blower 14 is arranged at the other side of the material sliding plate 2 and the material jumping plate 3 far away from the dust suction port 12. The air suction opening 13 and the air blower 14 generate air flow which penetrates through the jumping gap 30 and flows out of the box body 1 from the dust suction opening 12, after the air flow carries light impurities out of the materials, the light impurities are discharged out of the box body 1 from the dust suction opening 12 above the box body 1 along with the air flow, and the materials are kept falling under the action of gravity in the box body 1, so that the separation of the light impurities and the materials is realized.

Of course, the box body 1 does not need to be provided with the air suction opening 13 and the air blower 14 at the same time, and the box body 1 can be provided with one of the air blower 14 or the air suction opening 13 under the condition that the air flow can take away light impurities. The installation position of the blower 14 in the housing 1 may be set according to the desired airflow direction, the suction opening 13 may be set on the dust suction opening 12, and the position of the dust suction opening 12 on the housing 1 may also be set according to the desired airflow direction, for example, the dust suction opening 12 may be set on the side wall of the housing 1.

In the dust collection processing apparatus 100 of the present application, by providing the suction opening 13 or the blower 14 in the housing 1, an air flow passing through the material and flowing out of the dust collection opening 12 can be generated in the housing 1. The material falls on swift current flitch 2 after entering box 1 through feed inlet 11, after the material followed swift current flitch 2 from gathering materials high-end 21 to gathering materials low-end 22 roll-off swift current flitch 2, the material can scatter and fully contact with the air current in jumping gap 30, makes the air current can effectually take out light impurity from the material, and in addition, the material falls and can produce to roll and further scatter at jumping flitch 3, and the air current still can take away the light impurity that the material rolled the dispersion on jumping flitch 3. After light impurities are separated from materials under the driving of the air flow, the light impurities are discharged out of the box body 1 through the dust suction port 12 along with the air flow, at the moment, the materials fall to the bottom of the box body 1 under the action of gravity, and finally, the light impurities and the materials are completely separated.

In some embodiments, when the blower 14 is disposed in the box 1, the box 1 is provided with a third sliding chute 17, and the blower 14 is connected to the box 1 through a third sliding column 141 fitted at the third sliding chute 17. Therefore, the arrangement position of the blower 14 in the box body 1 can be adjusted, and the airflow direction in the box body 1 can be changed by adjusting the position of the blower 14, so that the airflow can achieve the optimal separation effect on light impurities and materials.

In the example of fig. 1 and 2, the blower 14 is connected to the box body 1 through the cooperation of the two third sliding columns 141 and the third sliding chute 17, the third sliding chute 17 is configured as an arc-shaped chute, and the adjustment of the flow direction angle of the airflow generated by the blower 14 can be realized through the movement of the third sliding columns 141 in the third sliding chute 17, so that the adjustment of the flow direction of the whole airflow in the box body 1 is realized.

In some embodiments, the material tripper plate 3 extends downwardly in a direction from the aggregate high end 21 to the aggregate low end 22, as shown in fig. 1. Under such structure, the material can follow original whereabouts direction and follow the landing of jumping flitch 3 after falling to jumping flitch 3, and jumping flitch 3 can not stop the whereabouts direction production of material to can keep the falling speed of material, prevent that the material from piling up on jumping flitch 3, keep the material in the state of scattering, be favorable to the separation of light impurity from the material.

In some embodiments, as shown in fig. 1, there are at least two material-skipping plates 3, at least two material-skipping plates 3 are sequentially distributed in a direction from the aggregate high end 21 to the aggregate low end 22, and between two adjacent material-skipping plates 3, the material-skipping plate 3 far from the material-skipping plate 2 is located below the material-skipping plate 3 near to the material-skipping plate 2. From this, also form into jump space 30 between two adjacent flitch 3, when the material fell along swift current flitch 2 and a plurality of flitch 3 of jumping in box 1, can pass through a plurality of jump spaces 30, make the material all can scatter and fully contact with the air current at a plurality of jump spaces 30 to the light impurity in the material can be taken out many times to the air current, makes the separation of light impurity and material more thorough. And the material falls on each material skipping board 3 and all can produce and roll and scatter thereby disperse out light impurity, through the roll of material on a plurality of material skipping boards 3, can realize the multiple dispersion of light impurity and material, and the light impurity that disperses on a plurality of material skipping boards 3 can be taken away to the air current, reduces the residue of light impurity in the material.

In some embodiments, as shown in fig. 1 and 2, the material-skipping plate 3 can be movably connected to the box body 1 to adjust the position or the angle of the material-skipping plate 3, or both. It will be appreciated that the type of material and the light impurity content of the material will affect the direction in which the material falls after sliding out of the aggregate lower end 22 of the chute plate 2.

The material jumping plate 3 is movably connected to the box body 1, and the material can be accepted by adjusting the position of the material jumping plate 3 when different materials are processed by the material jumping plate 3, so that the light impurities and the materials are dispersed. Therefore, the dust collection processing device 100 can be suitable for different materials, and the use flexibility is improved.

Further, the material jumping plate 3 is rotatably connected to the box body 1. Or, the box body 1 is provided with a first chute 15, and the material jumping plate 3 is matched at the first chute 15 through a first sliding column 31.

In the example of fig. 1 and 2, the material-skipping plate 3 is connected to the box body 1 through the cooperation of two first sliding posts 31 and the first sliding grooves 15, wherein the first sliding grooves 15 extend in the horizontal direction. The two first sliding pillars 31 can fix the position of the material tripping plate 3, so that the material tripping plate 3 is prevented from overturning, and meanwhile, the horizontal position of the material tripping plate 3 in the box body 1 can be adjusted by moving the first sliding pillars 31 in the first sliding grooves 15, so that the material tripping plate 3 can bear materials at different positions according to use requirements.

Of course, the number of the first slide posts 31 and the first slide grooves 15 is not limited to two, and for example, when the first slide posts 31 have a certain width to prevent the skip plate 3 from turning over, the number of the first slide posts 31 and the first slide grooves 15 may be set to one.

Further, the first chute 15 is not limited to the arrangement extending in the horizontal direction, and for example, the first chute 15 may also be arranged in the vertical direction. For another example, the first sliding groove 15 may be disposed along a direction forming an angle with the horizontal direction. Even more, the first sliding groove 15 may be configured as a structure of a plurality of sliding grooves in a shape of a Chinese character 'mi'.

In this application scheme, except that the material tripping plate 3 is connected with the box body 1 through the first sliding column 31 and the first sliding chute 15, the material tripping plate can also be rotatably connected to the box body 1, and the mode that the material tripping plate 3 is rotatably connected to the box body 1 is not limited. For example, the material jumping plate 3 is connected with the box body 1 through a rotating shaft, and the box body 1 is provided with a limiting structure of the rotating shaft for controlling the rotating angle of the rotating shaft, so that the material jumping plate 3 can be rotatably connected on the box body 1.

In addition, when the material that falls on swift current flitch 2 is more, the material probably is the form of piling up on swift current flitch 2, is unfavorable for the material to evenly scatter at the whereabouts in-process in jump space 30, through forming between material collecting plate 4 and swift current flitch 2 and spread material mouth 41, too much material can be blocked by material collecting plate 4 when the process is spread material mouth 41, makes the material can evenly be spread out thinly when passing through material spreading mouth 41, guarantees that the material can fully scatter through jump space 30 and skip flitch 3 to guarantee the separation effect of light impurity and material.

Further, the material collecting plate 4 is movably connected to the box body 1 to adjust the position or angle of the material collecting plate 4, or adjust the position and angle at the same time. Because the material sliding plate 2 is fixed in the box body 1, the relative position of the material collecting plate 4 and the material sliding plate 2 can be changed by adjusting the position of the material collecting plate 4 connected to the box body 1, and the size of the material spreading port 41 is changed.

In the use of the dust collection processing device 100 of the scheme, the position of the material collecting plate 4 can be adjusted according to the material bouncing position in the actual use, the blocking effect of the material collecting plate 4 on the bouncing material is ensured, the size of the material spreading port 41 can be changed, the excessive falling of the material from the material sliding plate 2 is prevented, the material is difficult to disperse, and the separation effect of light impurities and the material is influenced.

Specifically, the box body 1 is provided with a second chute 16, and the aggregate plate 4 is fitted at the second chute 16 through a second sliding column 42. In the example of fig. 1 and 2, the aggregate plate 4 is connected to the box body 1 by the fitting of two second sliding columns 42 and a second sliding chute 16, wherein the second sliding chute 16 extends in the vertical direction. Two second travelers 42 can be with the fixed position of board 4 that gathers materials, prevent that the upset from taking place for album flitch 4, simultaneously, through the removal of second travelers 42 in second spout 16, can realize the adjustment of album flitch 4 vertical position in box 1, make board 4 that gathers materials can adjust the position and change the size of spreading material mouth 41 according to the user demand.

Of course, the number of the second slide posts 42 and the second slide grooves 16 is not limited to two, and for example, when the second slide posts 42 have a certain width to prevent the material collecting plate 4 from being turned over, the number of the second slide posts 42 and the second slide grooves 16 may be set to one.

Further, the second chute 16 is not limited to the arrangement extending in the vertical direction, and for example, the second chute 16 may also be arranged in the horizontal direction. For another example, the second chute 16 may be disposed at an angle to the vertical. Even, the second chute 16 may be a structure formed by a plurality of chutes in a shape of a Chinese character mi.
