[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-4As shown, a kind of filter screen for crystallization device, including box 1, assembly groove 2 is set on the inner wall of box 1, multiple groups of sliding groove 3 are set on the inner wall of assembly groove 2, sliding block 4 is assembled in sliding groove 3, plate frame 5 is installed on sliding block 4, baffle 24 is installed on plate frame 5, plate frame 5 is assembled in assembly groove 2, plate slot 6 is set in plate frame 5, iron sheet 7 is installed on the top plate of plate frame 5, pulse electromagnet 8 is installed on the inner wall of assembly groove 2, pulse electromagnet 8 is located above iron sheet 7, multiple groups of spring 22 are installed on the inner wall of assembly groove 2, the top end of spring 22 is fixedly connected with the bottom side of plate frame 5, filter screen 9 is placed in plate slot 6, placing groove 10 is set on the inner wall of box 1, collecting box 11 is placed in placing groove 10, assembly groove 2 is U-shaped structure, control panel 12 is installed on the outer wall of box 1, control panel 12 is connected with pulse electromagnet 8 by internal circuit, feeding hopper 13 is installed on the top side of box 1, discharge hopper 14 is installed on the bottom side of box 1, stand 23 is installed on box 1, box door 15 is rotatably installed on box 1 by hinge, glass window 16 is arranged on box door 15;When working, the existing filter screen 9 for crystallization device needs to pour out the crystallization product after filtering, because filter screen 9 is easily blocked by crystallization product, the cleaning efficiency of filter screen 9 is low, and the collection efficiency of crystallization product is affected, by placing filter screen 9 in plate slot 6 of plate frame 5, closing box door 15, pouring the mixture of crystallization product and solution into box 1 from feeding hopper 13, then the crystallization product in the mixture is intercepted on filter screen 9, and the solution in the mixture is discharged from discharge hopper 14, to realize separating the crystallization product from the solution;

[0020] The pure solid crystallization product on filter screen 9 needs to be poured out for collection, and then dried, by taking out filter screen 9 from plate frame 5, then pouring out the crystallization product on filter screen 9, some crystallization product is still accumulated and blocked on filter screen 9, by placing collecting box 11 into placing groove 10 of box 1, then placing filter screen 9 reversely on plate frame 5, so that the upper surface of filter screen 9 faces downward;

[0021] After that, through the control panel 12, the sinusoidal current is passed into the pulse electromagnet 8 through the wire, so that the pulse electromagnet 8 is magnetized, and the sinusoidal current is switched every half cycle. When the sinusoidal current is switched every half cycle, the sinusoidal current disappears. The frequency of the sinusoidal current switching every half cycle is very high, so the frequency of the magnetic field generated by the pulse electromagnet 8 is also very high. The magnetic force generated by the pulse electromagnet 8 is instantaneous. The pulse electromagnet 8 generates a magnetic force that attracts the iron sheet 7 to the pulse electromagnet 8. The iron sheet 7 drives the shelf 5 to move vertically upward. The shelf 5 drives the filter screen 9 to move vertically upward. After that, the magnetic force disappears. Under the tension of the spring 22, the spring 22 pulls the shelf 5 to move vertically downward. The shelf 5 drives the filter screen 9 to move vertically downward. Because the switching frequency of the magnetic field generation and disappearance is very high, the filter screen 9 generates high-frequency vibration. The filter screen 9 shakes off the crystallization product accumulated and blocked thereon. The crystallization product is collected by the collection box 11. This realizes efficient cleaning of the filter screen 9 and efficient collection of the crystallization product. This is beneficial to improve the cleaning efficiency of the filter screen 9 and the collection efficiency of the crystallization product.

[0022] Please refer to Figure 5 As shown in the figure, the box door 15 is rotatably installed with a rotating shaft 17. A connecting plate 18 is fixedly sleeved on the rotating shaft 17. A first rod hole is formed in the connecting plate 18. A thread is formed in the inner wall of the first rod hole. A connecting seat 19 is installed on the outer wall of the box body 1. A second rod hole is formed in the connecting seat 19. A thread is formed in the inner wall of the second rod hole. A screw rod 20 is penetrated into the first rod hole and the second rod hole in the connecting plate 18 and the connecting seat 19. A knob 21 is installed on the screw rod 20. When the existing crystallization device uses the filter screen 9 to filter the crystallization product, the filter screen 9 needs to be disassembled and cleaned. Because the disassembly steps are complex, the disassembly efficiency of the filter screen 9 is low. By rotating the knob 21, the screw rod 20 is rotated and rotated out of the connecting seat 19. At this time, the connecting plate 18 and the connecting seat 19 are not fixedly connected by the screw rod 20. The box door 15 is opened, and the filter screen 9 is taken out of the shelf 5. This realizes quick disassembly of the filter screen 9 and is beneficial to improve the disassembly efficiency of the filter screen 9.

[0023] The working principle is that the existing filter screen 9 of the crystallization device needs to pour out the crystallization product for collection after filtering the crystallization product. Since the filter screen 9 is easily blocked by the crystallization product, the cleaning efficiency of the filter screen 9 is low, which affects the collection efficiency of the crystallization product. By placing the filter screen 9 in the plate groove 6 of the plate frame 5, closing the box door 15, pouring the mixture of the crystallization product and the solution into the box body 1 from the feeding hopper 13, and then the crystallization product in the mixture is intercepted on the filter screen 9, and the solution in the mixture is discharged from the discharge hopper 14, the crystallization product is separated from the solution; the pure solid crystallization product on the filter screen 9 needs to be poured out for collection, and then the next step of drying is carried out. By taking out the filter screen 9 from the plate frame 5, and then pouring out the crystallization product on the filter screen 9, some crystallization product will still accumulate and block on the filter screen 9. By placing the collection box 11 into the placing groove 10 of the box body 1, and then placing the filter screen 9 on the plate frame 5 in reverse, so that the upper surface of the filter screen 9 faces downward; then control the panel 12 to pass the sinusoidal current into the pulse electromagnet 8 through the wire, so that the pulse electromagnet 8 is magnetized. The sinusoidal current is switched between positive and negative half cycles. Every time the sinusoidal current is switched between positive and negative half cycles, the sinusoidal current disappears. The frequency of the sinusoidal current switching between positive and negative half cycles is very high, so the frequency of the magnetic field generated by the pulse electromagnet 8 is also very high. The magnetic force generated by the pulse electromagnet 8 is also instantaneous. The pulse electromagnet 8 generates a magnetic force that attracts the iron sheet 7 to move towards the pulse electromagnet 8. The iron sheet 7 drives the plate frame 5 to move vertically upward. The plate frame 5 drives the filter screen 9 to move vertically upward. Then the magnetic force disappears. Under the tension of the spring 22, the spring 22 pulls the plate frame 5 to move vertically downward. The plate frame 5 drives the filter screen 9 to move vertically downward. Since the switching frequency of the magnetic field generation and disappearance is very high, the filter screen 9 generates high-frequency vibration. The filter screen 9 vibrates and shakes off the crystallization product accumulated and blocked thereon. The crystallization product is collected by the collection box 11. The filter screen 9 is efficiently cleaned, the crystallization product is efficiently collected, the cleaning efficiency of the filter screen 9 is improved, and the collection efficiency of the crystallization product is improved.

[0024] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
