[0002] In the magnesium powder processing industry, magnesium ingots are important raw materials, and the efficiency and accuracy of their processing are crucial. Magnesium ingots need to be crushed during processing, but there are many problems with the conveying device after crushing when handling magnesium powder from magnesium ingots.

[0003] On the one hand, existing conveying devices are usually unable to achieve graded discharge. In the magnesium powder processing process, since magnesium powders of different particle sizes often have different uses and values, they need to be graded and discharged separately. However, traditional conveying devices can generally only perform a single conveying operation and cannot classify and transport magnesium powder according to its particle size. This requires a lot of extra time and effort for manual grading in the subsequent processing steps, which is not only inefficient but also increases production costs.

[0004] On the other hand, during the crushing process, the crushed magnesium powder cannot be discharged in time, and will be processed into smaller particles as the crushing device operates, resulting in waste; it will also cause magnesium powders of different particle sizes to mix together, affecting the stability of product quality. For example, in certain specific application scenarios, magnesium powder of a specific particle size range is required, and the mixed magnesium powder is difficult to meet this precise requirement, which may cause product performance to decline or fail to achieve the expected use effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1 to Figure 7, which is the first embodiment of the present invention, proposes a conveying device for magnesium powder processing, which is used to be installed on a crushing cylinder 1, and a crushing shaft 101 is rotatably arranged in the crushing cylinder 1, including an end cover 2, which is arranged at one end of the crushing cylinder 1, and one end of the crushing shaft 101 passes through the end cover 2, and the end cover 2 has a discharge port 201; a first screen is arranged at the discharge port 201; a temporary storage bin 3 is arranged at one end of the crushing cylinder 1, and is located below the end cover 2; a baffle plate 4 is relatively slidably arranged in the crushing cylinder 1, and after the baffle plate 4 slides, the crushing cylinder 1 is connected with the temporary storage bin 3 or the connection is cancelled.

[0025] In this embodiment, in order to solve the problem in the related art that it is inconvenient to discharge the magnesium ingot according to demand after it is crushed, a discharge port 201 is provided on the end cover 2 at one end of the crushing cylinder 1, and a first screen is installed on the discharge port 201. The crushing cylinder 1 is connected to the temporary storage bin 3 through the discharge port 201, and the connection is controlled by sliding the baffle plate 4. Through the cooperation of the temporary storage bin 3, the baffle plate 4 and the first screen, the connection state between the crushing cylinder 1 and the temporary storage bin 3 can be controlled, so that the appropriate discharge time can be selected according to the needs during the crushing of the magnesium ingot. After the magnesium ingot is crushed for a period of time, the baffle plate 4 can be slid first to connect the temporary storage bin 3 with the crushing cylinder 1, so that the magnesium powder that meets the requirements passes through the first screen and enters the temporary storage bin 3. The baffle plate 4 can protect the first screen to prevent the impact of the magnesium ingot during the crushing process from affecting the service life of the first screen. At the same time, the cooperation between the first screen and the baffle plate 4 can not only separate and transport the magnesium ingot to be crushed and the magnesium powder that meets the requirements in time, but also make the temporary storage bin 3 in a closed state when it is not connected to the crushing cylinder 1, which is convenient for drying the magnesium powder and preventing the crushed magnesium powder from getting damp.

[0026] Specifically, in the initial state, when adding magnesium ingots to the crushing cylinder 1, the baffle plate 4 slides downward and closes the discharge port 201. At this time, the magnesium ingot is crushed by the rotation of the crushing shaft 101. After crushing for a period of time, the baffle plate 4 is slid upward to connect the crushing cylinder 1 with the temporary storage bin 3. At this time, as the crushing shaft 101 continues to rotate, the magnesium powder that meets the requirements will pass through the first screen and enter the temporary storage bin 3. Then, the baffle plate 4 is slid downward so that the discharge port 201 is blocked by the baffle plate 4, and the magnesium ingot is continued to be crushed, while the temporary storage bin 3 is in a closed state, which is convenient for maintaining a dry environment and is not affected by the crushing bin loading. It is also convenient to dry the magnesium powder in the temporary storage bin 3 to prevent the magnesium powder from getting wet. By setting the baffle plate 4, the temporary storage bin 3 and the first screen, the magnesium powder that meets the requirements can be transported away in time, so that the crushed magnesium powder is in a suitable state, and because the input is timely, the crushed magnesium powder can be transported to the temporary storage bin 3 at any time according to the crushing situation, which can prevent the magnesium powder from being over-crushed and its particle size not meeting the requirements, thereby improving the quality of the magnesium powder and reducing the defective rate. It is only necessary to select the appropriate first screen according to the processing requirements.

[0027] Furthermore, the crushing shaft 101 has a first annular groove 1011 and a guide groove 1012. The guide groove 1012 is parallel to the axis of the crushing shaft 101. The guide groove 1012 is located above the first annular groove 1011 and is connected to the first annular groove 1011. It also includes a guide sleeve 5. One end of the guide sleeve 5 is arranged on the baffle plate 4. The guide sleeve 5 is sleeved on the crushing shaft 101; one end of the limit block 6 is arranged on the inner wall of the guide sleeve 5. After the guide sleeve 5 slides, the other end of the limit block 6 is located in the first annular groove 1011 or the guide groove 1012, so that the baffle plate 4 closes the discharge port 201 or rotates with the crushing shaft 101.

[0028] In this embodiment, a guide sleeve 5 is installed on the baffle plate 4, and the guide sleeve 5 can slide along the crushing shaft 101. When the guide sleeve 5 slides, one end of the limit block 6 is located in the first annular groove 1011 or the guide groove 1012. By pushing the guide sleeve 5 to slide, the baffle plate 4 can be driven to slide together to open or close the discharge port 201. When the limit block 6 is located in the first annular groove 1011, the baffle plate 4 closes the discharge port 201. When the crushing shaft 101 rotates, the limit block 6 slides in the first annular groove 1011. When it is necessary to open the discharge port 201, the guide sleeve 5 is pushed to make the limit block 6 slide along the guide groove 1012. At this time, the baffle plate 4 slides upward with the guide sleeve 5. At this time, when the crushing shaft 101 rotates, the limit block 6 abuts against the side wall of the guide groove 1012 and can rotate with the crushing shaft 101. Therefore, the baffle plate 4 will not always block the discharge port 201 directly above, and the efficiency of magnesium powder discharge will be faster.

[0029] Furthermore, it also includes a mounting tube 7, which is arranged on the end cover 2, and one end of the crushing shaft 101 passes through the end cover 2 and is rotatably connected to the mounting tube 7; the pushing plate 8 is slidably arranged in the mounting tube 7, and the pushing plate 8 has a first abutting surface 801 and a second abutting surface 802, and the height of the first abutting surface 801 is higher than that of the second abutting surface 802, and one end of the guide sleeve 5 abuts against the first abutting surface 801 or the second abutting surface 802; the first telescopic member 803 is used to drive the pushing plate 8 to slide.

[0030] In this embodiment, a mounting tube 7 is installed below the end cover 2. The design of the mounting tube 7 provides an installation space for the push plate 8 and the first telescopic member 803, and can also protect the push plate 8, the first telescopic member 803 and the crushing shaft 101, so as to prevent the mutual coordination between the structures from being affected by magnesium powder, thereby improving the service life of the equipment. The push plate 8 has a first abutting surface 801 and a second abutting surface 802, and there is a height difference between the two. The push plate 8 is pushed to slide by the first telescopic member 803, so that one end of the guide sleeve 5 can abut against the first abutting surface 801 or the second abutting surface 802, thereby pushing the guide sleeve 5 to slide, and the control is convenient and reliable.

[0031] Furthermore, the push plate 8 also has a transition surface 804 , and the first abutting surface 801 and the second abutting surface 802 are smoothly connected via the transition surface 804 .

[0032] In this embodiment, the first abutting surface 801 and the second abutting surface 802 are smoothly transitioned through the transition surface 804, so that the process of one end of the guide sleeve 5 moving between the first abutting surface 801 and the second abutting surface 802 is smoother and the noise during equipment operation is reduced.

[0033] Furthermore, there are two discharge ports 201 , which are spaced apart along the axial circumference of the grinding shaft 101 , and the baffle plate 4 has two baffle portions 401 , which correspond to the two discharge ports 201 .

[0034] In this embodiment, two discharge ports 201 are provided, and two material blocking parts 401 of the material blocking plate 4 are also provided correspondingly, and are symmetrically distributed. Therefore, the force on the guide sleeve 5 is more balanced during the sliding process, avoiding large friction between the inner wall of the guide sleeve 5 and the outer wall of the crushing shaft 101, thereby improving the service life of the entire equipment and reducing the noise during the operation of the equipment.

[0035] Furthermore, it also includes a grading conveying member 9, and there are multiple grading conveying members 9. The temporary storage bin 3 is connected to one of the grading conveying members 9; and both ends of the connecting tube 10 are respectively used to communicate with two adjacent grading conveying members 9.

[0036] In this embodiment, in order to further realize the graded transportation of magnesium powder, a graded conveying member 9 is provided to be connected with the temporary storage bin 3, and a plurality of graded conveying members 9 are provided, and adjacent graded conveying members 9 are connected through a connecting tube 10. After the magnesium powder enters the temporary storage bin 3, it can enter different graded conveying members 9 according to the degree of crushing, thereby realizing the classification of the magnesium powder. After the magnesium powder is subdivided according to the degree of crushing, the magnesium powder with a finer particle size after crushing can also be fully utilized, thereby improving the utilization efficiency of the magnesium powder and enriching the types of magnesium powder products.

[0037] Furthermore, the grading conveying member 9 includes a shell 901, which has an inlet 9011, an outlet 9012 and a connecting port 9013. The inlet 9011 and the outlet 9012 are respectively located at the two ends of the shell 901, the inlet 9011 is used to communicate with the temporary storage bin 3, the connecting port 9013 is opened on the side wall of the shell 901, and the two ends of the connecting cylinder 10 are respectively connected to the two connecting ports 9013; the second screen is arranged at the connecting port 9013; the screw shaft 902 is rotatably arranged in the shell 901; the first driving member 903 is used to drive the shell 901 to rotate.

[0038] In this embodiment, in addition to the inlet 9011 and the outlet 9012, the shell 901 of the grading conveyor 9 is provided with a connecting port 9013, and the inlet 9011 can be connected to the temporary storage bin 3. The inlet 9011 not connected to the temporary storage bin 3 remains closed, and other products can be added to the shell 901 through the inlet 9011 as needed. A second screen is provided at the connecting port 9013, wherein the mesh of the second screen in the grading conveyors 9 connected in sequence gradually decreases, thereby achieving the classification of magnesium powder, and the magnesium powder that can pass through the second screen enters the shell 901 of the next grading conveyor 9, and the magnesium powder that cannot pass through the second screen is transported to the outlet 9012 as the screw shaft 902 rotates.

[0039] Furthermore, there are two connecting ports 9013, which are respectively located on the upper and lower sides of the side wall of the shell 901. It also includes a driving wheel 11, which is rotatably arranged on the outer wall of the shell 901, and the driving wheel 11 is coaxial with the shell 901; a sealing plate 12 is arranged on the driving wheel 11, and after the driving wheel 11 rotates, the sealing plate 12 opens or closes the connecting port 9013.

[0040] In this embodiment, the upper and lower sides of the side wall of the housing 901 are respectively provided with a communication port 9013, and the communication port 9013 is opened or closed by a sealing plate 12. The sealing plate 12 is connected to the driving wheel 11. When there is a need for magnesium powder classification, the driving wheel 11 is rotated so that the driving wheel 11 drives the sealing plate 12 to rotate and open the communication port 9013, so that two adjacent communication ports 9013 are connected. When the magnesium powder does not need to be classified, in order to improve the efficiency of discharging, the driving wheel 11 can be rotated, and the sealing plate 12 rotates together and closes the communication port 9013.

[0041] Furthermore, the connecting cylinder 10 includes a connecting plate 1001, and there are two connecting plates 1001, which are respectively located on both sides of the connecting port 9013, one end of the connecting plate 1001 is set on the shell 901, and there is a gap between the other end and the adjacent shell 901, and the sealing plate 12 abuts against the side wall of the gap; there are two side plates 1002, and the left and right ends of the side plate 1002 are respectively connected to the two connecting plates 1001, and the upper and lower ends of the side walls of the side plates 1002 abut against the driving wheel 11.

[0042] In this embodiment, the connecting tube 10 is used to connect two adjacent grading conveying members 9. In order to ensure sealing performance and facilitate the movement of the sealing plate 12, one end of the connecting plate 1001 is connected to the shell 901, and a gap is provided between the other end and the adjacent shell 901 for the sealing plate 12 to pass through. During the movement of the sealing plate 12, it always abuts against the gap of the side wall. The two connecting plates 1001 and the two side plates 1002 cooperate to form a closed cavity, wherein the four sides of the side plate 1002 abut against the connecting plate 1001 and the driving wheel 11 respectively. In order to ensure sealing performance, a sealing strip can be added at the connection during installation, and the side plate 1002 and the connecting plate 1001 can be processed into an integrated structure.

[0043] Furthermore, the second abutting surface 802 is provided with a groove 8011 and also includes a ball 13 . There are multiple balls 13 , which are rotatably arranged at one end of the guide sleeve 5 away from the baffle plate 4 .

[0044] In this embodiment, when the baffle plate 4 slides and rises, one end of the guide sleeve 5 abuts against the first abutting surface 801. In order to make the guide sleeve 5 rotate more smoothly, a ball 13 is installed at one end of the guide sleeve 5 to change the sliding friction into rolling friction, so that the movement is smoother and the running noise is smaller. When the baffle plate 4 abuts against the second abutting surface 802, since the baffle plate 4 needs to close the discharge port 201, in order to ensure the stability of the baffle plate 4 when the crushing shaft 101 rotates, a groove 8011 is opened on the second abutting surface 802, and the ball 13 can enter the groove 8011.
