[0032] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a purification device for producing electronic grade silicon micropowder, comprising: a base 1, a tank body 6 and a cyclone 7 are fixedly mounted on the top of the base 1, a mounting plate 2 is fixedly mounted on the outer wall of the base 1, a motor 3 is fixedly mounted on the top of the mounting plate 2, a cam 4 is fixedly sleeved on the output shaft of the motor 3, a screen 5 is abutted on the outer wall of the cam 4, a material trough 8 and a movable trough 14 are respectively opened in the middle of the base 1, a cross bar 11 is fixedly mounted on the inner wall of the material trough 8, a first spring 12 is sleeved on the outer wall of the cross bar 11, and the first spring 12 The outer wall of the base 1 abuts against a slider 13, a stopper 21 is fixedly assembled at the bottom of the base 1, a round rod 19 is fixedly assembled on the outer wall of the stopper 21, a second spring 20 is sleeved on the outer wall of the round rod 19, the outer wall of the second spring 20 abuts against a positioning block 22, a slide plate 9 is fixedly assembled on the top of the positioning block 22, a limiting rod 15 is fixedly assembled on the outer wall of the positioning block 22, a connecting block 16 is fixedly assembled on the end of the limiting rod 15, a limiting wheel 17 is provided on the top of the connecting block 16, a pull rod 10 is fixedly assembled on the outer wall of the connecting block 16, and a groove 18 is provided at the bottom of the base 1. By setting the base 1, mounting plate 2, motor 3, cam 4, and screen 5 structure, during the operation of the purification device, the user can rotate the cam 4 by operating the motor 3, so that the cam 4 pushes the screen 5 to move during the rotation, so that the slider 13 follows the movement of the screen 5 and the slider 13 compresses the first spring 12, so that the screen 5 is in full contact with the purified silicon micropowder, thereby achieving the effect of screening the silicon micropowder, and there is no need for the user to screen the silicon micropowder after discharging, thereby improving the functionality and practicality of the purification device.

[0033] like Figure 3 and Figure 4 As shown, there are eight sliders 13, and the eight sliders 13 are divided into two groups, and the outer walls of the two groups of sliders 13 are fixedly assembled with the outer wall of the screen 5. Through the arrangement of the eight sliders 13, the screen 5 is fully limited by the sliders 13 and the cross bar 11 during the movement, so that the screen 5 can only move horizontally along the inner wall of the strip groove, thereby ensuring that the screen 5 cannot be displaced during the movement, thereby improving the stability of the screen 5 during the movement.

[0034] like Figure 6 and Figure 7 As shown, a through groove is provided at the top of the inner wall of the movable groove 14, and the inner wall of the through groove is slidably connected to the outer wall of the positioning block 22, the bottom of the slide plate 9 is slidably connected to the bottom of the inner wall of the material trough 8, a circular hole is provided on the outer wall of the stopper 21, and the inner wall of the hollow is slidably connected to the outer wall of the limit rod 15. Through the through groove, positioning block 22, material trough 8, slide plate 9 and circular hole structure, when the user screens the silicon micropowder through the screen 5, the positioning block 22 can be pulled by pulling the pull rod 10 to compress the second spring 20, so that the slide plate 9 vibrates to promote the silicon micropowder to pass quickly, thereby improving the discharge rate of the purification device, and also avoiding the accumulation of silicon micropowder inside the material trough 8 and causing material blockage. After the screening operation, the user can use the motor 3 to rotate the cam 4 to a state where it is not in contact with the screen 5, so that the user can directly pull out the screen 5, and then discharge the residue inside the material trough 8 to the outside of the purification device by pulling the pull rod 10, thereby improving the user's maintenance and cleaning efficiency of the purification device.

[0035] like Figure 2 and Figure 6 As shown, the diameter of the slide plate 9 is larger than the diameter of the through groove, and the stroke of the slide plate 9 is smaller than the distance between the end of the slide plate 9 away from the stopper 21 and the end of the material trough 8 close to the cyclone 7. By setting the slide plate 9 and the through groove structure, the diameter of the through groove can provide sufficient movement space for the movement of the slide plate 9, so as to ensure that the user can move the slide plate 9 by pulling the pull rod 10, so as to quickly discharge the silicon micropowder and avoid material blockage. At the same time, the stroke of the slide plate 9 can ensure that the material cannot leak to the outside of the base 1 through the through groove, thereby improving the preservation effect of the purification device on the silicon micropowder, thereby improving the sealing of the purification device and reducing material loss.

[0036] like Figure 6 and Figure 7 As shown, a rotating groove is provided on the top of the connecting block 16, and the inner wall of the rotating groove is rotatably connected to the outer wall of the limiting wheel 17, and the outer wall of the limiting wheel 17 is rollingly connected to the inner wall of the groove 18. Through the set rotating groove, limiting wheel 17 and groove 18 structure, when the user pulls the pull rod 10, the limiting rod 15 and the connecting block 16 are used to limit the positioning block 22, so as to ensure that the positioning block 22 moves in a straight line, and the limiting wheel 17 can roll along the inner wall of the groove 18, so as to reduce the generation of friction, thereby reducing the user's physical consumption, and reducing the wear of accessories, thereby improving the practicability of the purification device.

[0037] like Figure 1 and Figure 2As shown, the outer wall of the base 1 is provided with a strip groove, and the inner wall of the strip groove is slidably connected to the outer wall of the screen 5, the diameter of the screen 5 is larger than the diameter of the strip groove, and through the provided strip groove structure, when the motor 3 is in operation, the cam 4 is driven to rotate, and the cam 4 causes the screen 5 to be squeezed and moved due to its irregular shape, thereby achieving the effect of automatic silicon micropowder screening, so that the user does not need to screen the silicon micropowder after purification, thereby improving the user's silicon micropowder production and screening efficiency.

[0038] The technical solution provided by the utility model purifies the raw materials through the tank body 6, and the purified silicon micropowder enters the material trough 8. At this time, the user can drive the cam 4 to rotate through the motor 3 to move the screen 5. When moving, the screen 5 will drive the slider 13 to compress the first spring 12, so that the screen 5 will vibrate, thereby achieving the effect of screening the purified silicon micropowder, and there is no need for the user to purify the silicon micropowder again after purification, thereby improving the user's operating efficiency. During the screening process, the user can move the slide plate 9 by pulling the pull rod 10, so that the silicon micropowder vibrates due to the movement of the slide plate 9, thereby accelerating the passing speed of the material and further improving the user's operating efficiency. After the operation is completed, the user can also pull out the screen 5, and then pull the pull rod 10, so that the slide plate 9 pushes the residue to the outside of the purification device, thereby improving the user's maintenance efficiency of the equipment.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] A person skilled in the art will appreciate that all or part of the steps in the above-mentioned embodiment method can be completed by instructing related hardware through a program, and the program can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
