Description

Technical Field

[0001] The present application relates to the technical field of mineral processing equipment, and in particular to a sorting structure for an intelligent ore dry sorting machine. Background Art

[0002] Gangue is a solid waste discharged during the coal mining and washing process. Due to the thin rock layer in the middle of the coal seam, gangue is inevitable in the coal mining process. Therefore, mineral processing is an indispensable process in mining operations.

[0003] Among them, X-ray intelligent mineral separation machine is the most commonly used mineral separation machine. Figure 1 and Figure 2 As shown, the coal and gangue mixture is sent to the imaging area of ​​the X-ray imaging camera located in the frame 1 through the transmission belt 2, and photographed, identified and analyzed. Then, the working state of the jet solenoid valve 3 in the frame 1 is regulated by the control system, and the clean coal and gangue are diverted to different channels for sorting operations.

[0004] However, this method has a fixed blowing range of the air jet solenoid valve 3, while the size of the coal and gangue is uncertain, and their positions on the conveyor belt 2 are uncertain, which results in the gangue at the wind edge of the air jet solenoid valve 3 being subjected to a smaller force. In the process of mineral processing, it is very easy to cause the larger mass of gangue at the wind edge to fall into the clean coal channel due to the smaller force, thereby greatly affecting the separation accuracy of the mineral processing machine.

[0005] Moreover, in the process of improving the sorting accuracy by multiple sorting, the sorting efficiency of the ore dressing machine for coal is reduced, and the stability and reliability are poor.

[0006] Therefore, there is an urgent need for an air jet mechanism for an X-ray mineral separation machine to solve the defects existing in the above-mentioned existing X-ray mineral separation machine during actual operation. Summary of the Invention

[0007] The present application proposes a sorting structure for an intelligent ore dry sorting machine, which has the function of automatically adjusting the coverage range of the jet mechanism according to the size of the gangue, so that it can always be in the center of the wind, and will not cause large-mass gangue to flow into the clean coal channel due to the small wind force. It has the advantages of high coal sorting accuracy and efficiency, and is used to solve the problem of existing X-ray mineral processing machines in which the blowing range of the jet solenoid valve 3 is fixed, while the size of coal and gangue is uncertain, and their position on the conveyor belt 2 is uncertain, which leads to the gangue at the wind edge of the jet solenoid valve 3 being subjected to a small force, and in the process of mineral processing operations, it is very easy to cause large-mass gangue at the wind edge to fall into the clean coal channel due to the small force, thereby greatly affecting the sorting accuracy of the mineral processing machine.

[0008] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a sorting structure for an intelligent ore dry sorting machine, comprising a connecting splint movably sleeved on a frame roller, a hollow shaft fixedly sleeved on the other side of the inner cavity of the connecting splint, and an outer sleeve movably sleeved on the outer surface of the hollow shaft, an inner groove is provided on the outer surface of the outer sleeve, and a support plate extending to the outside of the outer sleeve through the inner groove is elastically sleeved on the outer surface of the hollow shaft, and a connecting groove connected to its inner cavity is provided on the outer surface of the outer sleeve and at a corresponding position of the support plate, and an air jet hole connected to its upper and lower ends is provided inside the support plate.

[0009] Furthermore, in the initial state, the conveyor belt, the connecting splint and the top end of the support plate are located on the same horizontal plane. At the same time, the connecting groove on the outer sleeve and the air injection holes on the support plate are staggered with each other in the initial state.

[0010] Furthermore, the air jet holes are arranged in an arc-shaped trajectory, and their openings at the top of the support plate are inclined upward.

[0011] Furthermore, a magnet is fixedly mounted on the outer surface of the support plate facing the conveyor belt, and a ferromagnetic material is fixedly mounted at a corresponding position inside the support plate, which attracts the magnet and generates suction.

[0012] Furthermore, a magnet is fixedly installed on the outer surface of the support plate facing the side of the conveyor belt, and corresponds to the electromagnet in the electromagnetic component fixedly installed on the outer surface of the hollow shaft. At the same time, the electromagnet in the electromagnetic component forms a feedback connection with the X-ray imaging camera through the control system.

[0013] Furthermore, the electromagnet on the electromagnetic component and the magnet on the support plate have opposite magnetic poles in the initial state and form an attractive force to ensure that the top of the support plate and the top of the connecting clamp are located on the same plane in the initial state.

[0014] Furthermore, the other end of the connecting splint is configured as a concave curved surface structure having the same curvature as the outer surface of the outer sleeve, and the concave curved surface of the connecting splint is in contact with the outer surface of the outer sleeve.

[0015] The present invention has the following technical effects:

[0016] The present application provides a sorting structure for an intelligent ore dry sorting machine. The arrangement of the hollow shaft and the structure thereon can automatically press down different numbers of support plates according to the different sizes of gangue, and make it rotate clockwise along the central axis of the outer sleeve, connecting the connecting groove and the air jet hole and connecting the high-pressure airflow, so that the wind force exerted on the gangue is more uniform, and ensures that the coal or gangue on it is affected by different wind forces and diverted to different channels, and will not flow into the clean coal channel due to the small wind force exerted on the gangue at the edge and with larger mass, thereby effectively improving the sorting accuracy and efficiency of the coal by the ore dressing machine.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] like Figure 3 、 Figure 5 As shown, a sorting structure for an intelligent ore dry sorter includes a connecting splint 4 movably sleeved on the roller of the frame 1, and one end of the connecting splint 4 is set as a curved structure to contact the end surface of the conveyor belt 2, and the top of the connecting splint 4 is flush with the top of the conveyor belt 2. The other side of the inner cavity of the connecting splint 4 is fixedly sleeved with a hollow shaft 5 whose end is connected to the high-pressure air pump through a hose, and an outer sleeve 6 is movably sleeved on the outer surface of the hollow shaft 5, as shown in FIG. Figure 4 、 Figure 6 As shown, the outer surface of the outer sleeve 6 is provided with several groups of inner grooves 7 arranged in a linear array, and the outer surface of the hollow shaft 5 is elastically sleeved with several groups of support plates 8 extending to the outside of the outer sleeve 6 through the inner grooves 7, and when the support plates 8 at different positions are subjected to downward pressure, the support plates 8 at the corresponding positions rotate along the central axis of the outer sleeve 6, and thus different numbers of support plates 8 can be automatically pressed down according to the different sizes of gangue, and several groups of connecting grooves 9 connected to the inner cavity are provided on the outer surface of the outer sleeve 6 and at corresponding positions of the support plates 8, and air jet holes 10 connected to the upper and lower ends thereof are provided inside the support plates 8. When the coal or gangue moves to the top of the support plate 8 via the conveyor belt 2 and the connecting splint 4, the support plate 8 is subjected to downward pressure and rotates along the central axis of the outer sleeve 6, and connects the connecting grooves 9 and the air jet holes 10 to connect to the high-pressure airflow, so that the coal or gangue on it is affected by different wind forces and diverted to different channels, thereby completing the coal sorting operation.

[0029] like Figure 3 、 Figure 5 As shown, in the present technical solution, in order to ensure that the coal or gangue transported on the conveyor belt 2 flows smoothly to the top of the support plate 8, in the initial state, the conveyor belt 2, the connecting splint 4 and the top of the support plate 8 are located on the same horizontal plane. At the same time, the connecting groove 9 on the outer sleeve 6 and the air injection hole 10 on the support plate 8 are in a staggered state in the initial state, and in the process that the support plate 8 is subjected to pressure and rotates clockwise along the central axis of the outer sleeve 6, they gradually overlap and connect with the connecting groove 9.

[0030] like Figure 6As shown, in the present technical solution, the air jet holes 10 are arranged in an arc-shaped trajectory, and their openings at the top of the support plate 8 are inclined upward, so as to effectively increase the impact force exerted by the high-pressure airflow flowing in the air jet holes 10 on the gangue on the support plate 8, thereby effectively preventing it from falling into the clean coal channel.

[0031] like Figure 6 As shown, in the present technical solution, a magnet 11 is fixedly installed on the outer surface of the support plate 8 and on the side facing the conveyor belt 2, and a ferromagnetic material is fixedly installed at a corresponding position inside the support plate 8, which attracts the magnet 11 and generates suction, thereby ensuring that the top end of the support plate 8 and the top end of the connecting splint 4 remain flush in the initial state. At the same time, after the support plate 8 is subjected to pressure and rotates clockwise along the central axis of the outer sleeve 6, it can automatically return to its initial position.

[0032] like Figure 6 、 Figure 7 As shown, in the present technical solution, a magnet 11 is fixedly mounted on the outer surface of the support plate 8 and on the side facing the conveyor belt 2, and corresponds to several groups of electromagnets in the electromagnetic component 12 fixedly mounted on the outer surface of the hollow shaft 5. At the same time, several groups of electromagnets in the electromagnetic component 12 are respectively feedback-connected with the X-ray imaging camera through a control system, and can adjust the suction force of the electromagnets in the electromagnetic component 12 on the magnet 11 on the support plate 8 according to the volume of the imaged gangue, or even apply a repulsive force, to ensure that the support plate 8 rotates at different angles and regulates the size of the high-pressure airflow flowing in the air jet hole 10, effectively avoiding the problem that the gangue cannot press down the support plate 8 and connect the air jet hole 10 and the connecting groove 9 due to its small volume and mass, causing it to flow into the clean coal channel.

[0033] like Figure 5 、 Figure 6 As shown, in the present technical solution, the electromagnet on the electromagnetic component 12 and the magnet 11 on the support plate 8 have opposite magnetic poles in the initial state and form an attractive force to ensure that the top end of the support plate 8 and the top end of the connecting splint 4 are located on the same plane in the initial state, and the support plate 8 will not tilt due to its own weight, thereby causing the problem of automatic connection between the jet hole 10 thereon and the connecting groove 9 on the outer sleeve 6.

[0034] like Figure 1 As shown, in the present technical solution, in order to ensure a tight fit between the connecting splint 4 and the support plate 8 and prevent vibration impact on the coal or gangue transported thereon, the other end of the connecting splint 4 is set to an inwardly concave curved surface structure with the same curvature as the outer surface of the outer sleeve 6, and the inwardly concave curved surface of the connecting splint 4 is in contact with the outer surface of the outer sleeve 6.
