DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a screening device for mining ore powder, including a processing box 1, the outer wall of the processing box 1 is provided with two movable holes 2, the top of the processing box 1 is provided with a mounting hole 3, one side of the outer wall of the processing box 1 is fixedly provided with two sets of hinges 4, a sealing door 5 is fixedly provided between the outer walls of the two sets of hinges 4, one side of the outer walls of the two sealing doors 5 is fixedly provided with a handle 6, the inner walls of the two movable holes 2 are movably inserted with a connecting rod 7, a screening drum 8 is fixedly provided between the outer walls of the two connecting rods 7, a mounting frame 9 is fixedly provided on the outer wall of the screening drum 8, a group of shaft holes 10 are provided on the outer wall of the mounting frame 9, and one side of the outer wall of the mounting frame 9 is fixedly provided with Motor 11, the output end of motor 11 is fixedly installed with a rotating shaft 12, and the inner surface wall of a group of shaft holes 10 is movably inserted with the outer surface wall of the rotating shaft 12, the outer surface wall of the rotating shaft 12 is fixedly sleeved with a baffle 13, a motor 2 is fixedly installed on one side of the outer wall of the processing box 1, and the output end of motor 2 14 is fixedly connected to one side of the outer wall of one of the two connecting rods 7, a silo 15 is fixedly installed on the top of the processing box 1, the output end of the silo 15 is fixedly connected with a discharge pipe 16, and the inner surface wall of the mounting hole 3 is fixedly inserted with the outer surface wall of the discharge pipe 16, the output end of the discharge pipe 16 is fixedly connected with an electric discharge valve 17, and the top of the inner wall of the processing box 1 contacts with a material holding box 18.

[0025] The effect achieved by the entire embodiment 1 is that after the device is started, the motor 2 14 starts working, driving a connecting rod 7 to rotate inside the movable hole 2, and then the connecting rod 7 causes the screening drum 8 and the other connecting rod 7 to rotate together. When the mounting frame 9 reaches the top of the screening drum 8, the motor 2 14 stops working, driving the screening drum 8 to start rotating, and then the motor 1 11 starts to start, causing the rotating shaft 12 to rotate inside a group of shaft holes 10. At this time, the baffle 13 fixedly mounted on the outer wall of the rotating shaft 12 is driven to rotate together, changing from a horizontal state to a vertical state. At this time, the electric discharge valve 17 starts to open, and the mineral powder inside the silo 15 is discharged through the discharge pipe 16 under the action of gravity, and then passes through the mounting frame 9 into the screening drum 8. When the mineral powder inside the screening drum 8 reaches a certain amount, the electric discharge valve 17 is closed, and at the same time, the motor 1 1 will drive the baffle plate 13 to rotate again through the rotating shaft 12, so that it remains horizontal and the mounting frame 9 is closed to prevent the internal mineral powder from spilling out through the mounting frame 9 when the screening drum 8 rotates. After the loading is completed, the motor 2 14 is started to drive the screening drum 8 to rotate through the connecting rod 7, and then the qualified mineral powder will pass through the screening drum 8 and fall into the material holding box 18 below. After the mineral powder screening is completed, the device can repeat this step to ensure the continuity of the screening work. People can easily carry qualified mineral powder by moving the material holding box 18. When there are too many large-particle mineral powders in the screening drum 8, it is only necessary to place the empty material holding box 18 under the screening drum 8, and then the motor 2 14 drives the mounting frame 9 to the top of the material holding box 18. At this time, the motor 11 is started to open the mounting frame 9 by rotating the baffle plate 13, and the large-particle mineral powder will fall into the material holding box 18.

[0026] Embodiment 2, as Figure 2-Figure 5 As shown, an air detector 19 is provided on one side of the inner wall of the processing box 1, a control panel 20 is provided on one side of the outer wall of the processing box 1, the output end of the processing box 1 is fixedly connected to an air outlet pipe 21, the output end of the air outlet pipe 21 is fixedly connected to a dust processor 22, and one side of the outer wall of the processing box 1 is fixedly connected to one side of the outer wall of the dust processor 22.

[0027] The effect achieved by the entire embodiment 2 is that a processor is provided inside the control panel 20, and people can control the operation of the device through the control panel 20. When the processing box 1 is working, the air detector 19 can monitor the internal air quality in real time. When it is found that the dust content in the air is high, the relevant signal will be transmitted to the control panel 20. The control panel 20 randomly starts the dust processor 22, and the dust processor 22 will suck the dust-containing gas into the internal processing through the exhaust pipe 21. The processing box 1 is not a sealed structure, and there is a certain gap between the box door and the processing box 1. When the air inside the processing box 1 is sucked into the dust processor 22, the outside air will enter the processing box 1 through these gaps to avoid the formation of negative pressure inside the processing box 1. There is too much dust when the mineral powder is screened, which not only pollutes the air, but also causes damage to the respiratory system of workers who inhale these dusts for a long time.

[0028] Working principle: The user can accurately control the operation process of the device through the control panel 20 and its built-in processor. After the device is activated, the motor 2 14 starts immediately, driving the connecting rod 7 to rotate in the movable hole 2, thereby driving the screening drum 8 and the other connecting rod 7 to rotate synchronously. When the mounting frame 9 moves to the preset position at the top of the screening drum 8, the motor 2 14 pauses, and then the motor 1 11 starts to drive the rotating shaft 12 to rotate in the shaft hole 10. During this process, the baffle 13 fixed on the rotating shaft 12 changes from a horizontal state to a vertical state, and the electric discharge valve 17 opens, allowing the mineral powder in the silo 15 to pass through the mounting frame 9 through the discharge pipe 16 under the action of gravity and enter the screening drum 8. Once the mineral powder in the screening drum 8 reaches the set amount, the electric discharge valve 17 is closed, and the motor 1 11 drives the rotating shaft 12 again to return the baffle 13 to a horizontal state, closing the mounting frame 9 to prevent the mineral powder from leaking out. After the loading is completed, the motor 2 14 restarts to drive the screening drum 8 to rotate, and the qualified mineral powder falls into the material box 18 below through the screen. , which is convenient for subsequent transportation, and the screening cycle can be carried out continuously to ensure the screening efficiency. People can rotate the sealed door 5 through the handle 6 and the hinge 4 to open the sealing door 5 and take out the material holding box 18. When too much large-particle mineral powder accumulates in the screening cylinder 8, it is only necessary to place the empty material holding box 18 below it, and the motor 2 14 drives the mounting frame 9 to come above the material holding box 18. The motor 1 11 controls the baffle 13 to rotate and open the mounting frame 9, so that the large-particle mineral powder falls into the material holding box 18 for collection. In addition, the processing box 1 has a built-in air detector 19, which can continuously monitor the internal air quality. Once it is found that the dust concentration exceeds the standard, it sends a signal to the control panel 20, and then starts the dust processor 22. The processor inhales the dust-containing gas through the outlet pipe 21 for processing, which effectively reduces the dust pollution to the air during the screening process and protects the respiratory health of the operator. The non-completely sealed design of the processing box 1 leaves a gap between the box door and the processing box 1, which ensures that when the internal air is extracted, the outside air can be naturally replenished to prevent the formation of negative pressure.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
