[0024] The worker needs to pre-screen the iron powder before production, and the mixture has impurities. The mixture is transported to the left upper surface of the first filter plate 10 through the front-end transportation structure. Due to the inclined angle of the first filter plate 10, and due to the driving structure of the lower surface of the screening box 4, the mixture on the upper surface of the first filter plate 10 will slide to the right end. At this time, the first motor 6 is started. Since the output shaft of the first motor 6 is fixedly connected with the threaded rod 7, the scraper 8 connected with the threaded surface of the threaded rod 7 is driven to slide along the inner surface of the chute 9. The upper surface of the lower part of the chute 9 is at the same reference surface as the upper surface of the first filter plate 10, so as to drive the impurities stuck in the hole of the first filter plate 10 to be scraped off.
[0025] Wherein, the upper surface of the first filter plate 10 is fixedly connected with a fixed column 11, the inside of the fixed column 11 is rotatably connected with a connecting block 12, one end of the connecting block 12 is fixedly connected with a curved baffle 13, the left side surface of the curved baffle 13 is provided with a insertion hole 14, the insertion hole 14 is movably connected with a special-shaped plug 15, and the special-shaped plug 15 penetrates the left wall of the screening box 4.
[0026] When the worker transports the mixture to be screened to the upper surface of the first filter plate 10, due to the shape of the curved baffle 13, the mixture will not fall onto the surface of the threaded rod 7. When the threaded rod 7 is used for a long time, the special-shaped plug 15 located on the left side surface of the screening box 4 can be pulled out from the inside of the insertion hole 14. Since the connecting block 12 is fixedly connected with the curved baffle 13, and the connecting block 12 is rotatably connected in the fixed column 11, the left end of the curved baffle 13 can be turned up, so that the threaded rod 7 is exposed, and lubricating oil can be added at the threaded part of the threaded rod 7.
[0027] Wherein, the driving structure includes a second motor 16 fixedly installed on the upper surface of the middle part of the fixed mounting support 1, the output shaft of the second motor 16 is fixedly connected with a driving disc 17, the surface of the driving disc 17 is hinged with a hinge rod 18, the upper end of the hinge rod 18 is hinged with a hinge block 19, and the hinge block 19 is fixedly connected with the lower surface of the screening box 4.
[0028] By starting the second motor 16 to drive the rotation of the driving disc 17, the front end surface of the driving disc 17 has an eccentric cylinder, the eccentric cylinder of the driving disc 17 is hinged with the hinge rod 18, and the hinge rod 18 is hinged with the hinge block 19, so as to drive the screening box 4 to move up and down in the groove on the inner surface of the limiting baffle 3.
[0029] Wherein, the auxiliary structure includes a limiting sliding rod 20 fixedly connected to the upper surface of the supporting plate 2, and a spring assembly 21 fixedly connected to the upper surface of the supporting plate 2. The upper surface of the spring assembly 21 is fixedly connected with the lower surface of the screening box 4.
[0030] The limiting slide bar 20 prevents the spring assembly 21 from deforming, extends the service life of the spring assembly 21, and the spring assembly 21 assists the drive structure to realize the up and down vibration and support force of the screening box 4.
[0031] Among them, a limiting hole 22 is opened on the outer surface of the screening box 4, and the limiting hole 22 is movably connected to the limiting slide rod 20.
[0032] The presence of the limiting hole 22 further restricts the lifting and lowering of the screening box 4. When the screening box 4 descends, since the screening box 4 is fixedly connected to the upper surface of the spring assembly 21, and the limiting slide rod 20 is movably connected to the upper end of the spring assembly 21, the design of the limiting hole 22 provides space for the limiting slide rod 20.
[0033] The inner surface of the screening box 4 is fixedly connected to a flow guide plate 23, which is fixedly connected to the lower surface of the first filter plate 10. The lower inner surface of the screening box 4 is fixedly connected to a second filter plate 24.
[0034] The design of the diversion plate 23 prevents untimely screening, which would cause the mixture passing through the pores of the first filter plate 10 to be transported out from the upper outlet of the second filter plate 24 without being screened on the surface of the second filter plate 24. The second filter plate 24 has a different pore size than the first filter plate 10, which allows for finer screening.
[0035] Among them, a support column 25 is fixedly connected to the surface of the first filter plate 10, and a limit ring 26 is fixedly connected to the upper surface of the support column 25. The inside of the limit ring 26 is rotatably connected to the right end curved surface of the threaded rod 7.
[0036] The threaded rod 7 is protected by the combined action of the limiting ring 26 and the support column 25, preventing the threaded rod 7 from deforming due to long-term operation, thereby increasing maintenance costs. The support column 25 is cylindrical, which allows the mixture that does not pass through the aperture of the first filter plate 10 to be transported out more smoothly.
[0037] Working principle and usage process of this utility model:
[0038] Before production, the iron concentrate needs to be pre-screened. The mixture contains impurities. The mixture is transported to the upper left surface of the first filter plate 10 through the front-end transport structure. Due to the inclined setting of the first filter plate 10, the drive structure on the lower surface of the screening box 4, in conjunction with the vibration of the auxiliary structure, causes the mixture on the upper surface of the first filter plate 10 to slide to the right. At this time, the first motor 6 is started. Since the output shaft of the first motor 6 is fixedly connected to the threaded rod 7, it drives the scraper 8, which is threaded to the surface of the threaded rod 7, to slide along the inside of the slide groove 9. The lower upper surface of the slide groove 9 is on the same reference plane as the upper surface of the first filter plate 10, thereby scraping off the impurities stuck in the holes of the first filter plate 10.
[0039] When the staff transports the mixture to be screened to the upper surface of the first filter plate 10, due to the shape of the curved baffle 13, the mixture will not fall to the surface of the threaded rod 7. When the threaded rod 7 is used for a long time, the special-shaped plug 15 located on the left side surface of the screening box 4 can be pulled out from the inside of the insertion hole 14. Since the adapter block 12 is fixedly connected with the curved baffle 13, and the adapter block 12 is rotatably connected inside the fixed column 11, the left end of the curved baffle 13 can be flipped upward, thereby exposing the threaded rod 7, so as to add lubricating oil at the threads of the threaded rod 7.
[0040] By starting the second motor 16 to drive the rotation of the driving disc 17, the front end surface of the driving disc 17 has an eccentric cylinder, the eccentric cylinder of the driving disc 17 is hinged with the hinge rod 18, and the hinge rod 18 is hinged with the hinge block 19, thereby driving the screening box 4 to move up and down along the groove inside the limiting baffle 3.
[0041] The limiting slide rod 20 prevents the deformation of the spring assembly 21, increases the service life of the spring assembly 21, and the spring assembly 21 assists the driving structure to realize the up-and-down vibration and supporting force of the screening box 4.
[0042] The existence of the limiting hole 22 further limits the lifting of the screening box 4. When the screening box 4 descends, since the screening box 4 is fixedly connected to the upper surface of the spring assembly 21, and the limiting slide rod 20 is movably connected inside the upper end of the spring assembly 21, therefore, the design of the limiting hole 22 reserves space for the limiting slide rod 20.
[0043] Through the design of the drainage plate 23, the screening is prevented from being not timely, so that the mixture passing through the pore diameter of the first filter plate 10 is not screened on the surface of the second filter plate 24, but is transported out from the upper end outlet of the second filter plate 24. The second filter plate 24 and the first filter plate 10 have different pore diameters, so that more fine screening can be performed.
[0044] Through the joint action of the limiting ring 26 and the supporting column 25, the threaded rod 7 is protected, which prevents the threaded rod 7 from deforming due to long-time work, thereby increasing the maintenance cost. The supporting column 25 is in a cylindrical shape, so that the mixture not passing through the pore diameter of the first filter plate 10 is more smoothly transported out.

[0046] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
