[0002] Ferrous sulfate is an inorganic substance with the chemical formula of FeSO4. It is a white powder with no odor. Its crystalline hydrate is a heptahydrate at room temperature, commonly known as "green vitriol". Ferrous sulfate is mainly used to make iron salts, inks, magnetic iron oxides, water purifiers, disinfectants, and iron catalysts; it is used as a coal dye, tanning agent, bleaching agent, wood preservative, and compound fertilizer additives, as well as processing ferrous sulfate monohydrate, etc.

[0003] Ferrous sulfate crystals are prepared by crystallization of ferrous sulfate solution inside a crystallization device. There are several methods for preparing ferrous sulfate crystals, namely: freezing crystallization, intermittent vacuum crystallization, cooling crystallization after evaporation concentration, sulfuric acid method for producing titanium dioxide as a by-product, and metallic iron reduction method.

[0004] After the ferrous sulfate crystallizes, the crystals need to be collected manually, which takes a long time and is inconvenient to operate; therefore, it does not meet the existing needs. In this regard, we propose a crystal crystallizer. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 3 As shown, a crystal crystallizer comprises an outer shell 1, a sealing cover 2 is detachably installed on the top of the outer shell 1, a discharge pipe 3 and two liquid discharge pipes 4 are fixed at the bottom of the outer shell 1, the discharge pipe 3 is located between the two liquid discharge pipes 4, a separation bin 6 is arranged inside the outer shell 1, a crystallization bin 5 is arranged above the separation bin 6, an opening is arranged at the bottom of the bottom end of the crystallization bin 5 and a solenoid valve is installed at the opening, a support ring 7 is fixed inside the separation bin 6, two movable filter screens 8 are slidably installed on the inner side of the support ring 7, a return spring 12 is installed between the movable filter screen 8 and the support ring 7, and the discharge A lifting collection pipe 10 is installed at the top of the material pipe 3, and guide bars 9 are fixed at the bottom of the two movable filter screens 8. The bottom ends of the guide bars 9 are inclined toward the inner wall of the outer shell 1. An annular filter screen 14 is fixed at the top of the lifting collection pipe 10. After the ferrous sulfate solution crystallizes inside the crystallization bin 5, the solenoid valve at the bottom of the crystallization bin 5 is opened to allow the ferrous sulfate solution and the crystal instrument to flow into the separation bin 6, and then the solution will pass through the two movable filter screens 8 and flow out from the two liquid outlet pipes 4, and the ferrous sulfate crystals will be intercepted by the two movable filter screens 8 to achieve the separation of the ferrous sulfate crystals.

[0023] like Figure 2 and Figure 4 As shown, a drainage block 15 is installed on the inner side of the top of the lifting collection tube 10, and filling blocks 16 are installed on both sides of the drainage block 15 and between the lifting collection tube 10. The center of the upper surface of the drainage block 15 protrudes upward in a cone shape, and the top of the filling block 16 is an inclined surface and the slope of the inclined surface is consistent with the slope of the surface protruding at the center of the drainage block 15. The bottom ends of the drainage block 15 and the two filling blocks 16 are fixed with a fixing rod 17. The fixing rod 17 at the bottom end of the drainage block 15 is fixed on the inner wall of the lifting collection tube 10, and the fixing rod 17 at the bottom end of the filling block 16 is fixed on the inner wall of the discharge pipe 3. The drainage block 15 and the two filling blocks 16 will drain the liquid that falls on the top of the lifting collection tube 10 to prevent the liquid from accumulating above the lifting collection tube 10 and flowing out along the lifting collection tube 10 when the lifting collection tube 10 moves up.

[0024] like Figure 4 As shown, the bottom end of the lifting and collecting tube 10 is slidably inserted into the top end of the discharge tube 3, and a lifting block 13 is fixed to the outer side of the bottom end of the lifting and collecting tube 10. The lifting block 13 is slidably installed in the inner wall of the outer shell 1, and an electric telescopic rod 11 is installed below the lifting block 13. The effective range of the electric telescopic rod 11 is less than or equal to the pipe length of the lifting and collecting tube 10 located inside the discharge tube 3. The electric telescopic rod 11 is used to push the lifting block 13 and the electric telescopic rod 11 to move, so that the annular filter 14 can contact the guide bar 9 and push the guide bar 9 and the movable filter 8 to move, so that the two movable filter screens 8 are separated smoothly, allowing the ferrous sulfate crystals to fall.

[0025] Working principle: After the ferrous sulfate solution crystallizes inside the crystallization bin 5, the solenoid valve at the bottom of the crystallization bin 5 is opened, so that the ferrous sulfate solution and the crystal instrument flow into the separation bin 6, and then the solution passes through the two movable filter screens 8 and flows out from the two liquid outlet pipes 4, while the ferrous sulfate crystals are intercepted by the two movable filter screens 8 to achieve the separation of the ferrous sulfate crystals. After the ferrous sulfate crystals are separated, the electric telescopic rod 11 is powered on and starts to drive the lifting block 13 and the lifting collection pipe 10 to move upward. At this time, the annular filter screen 14 and the drainage block 15 will move simultaneously with the lifting collection pipe 10, and the filling block 16 When the annular filter screen 14 moves, it will squeeze the guide bar 9 and make the guide bar 9 drive the mobile filter screen 8 to move toward the inner wall of the outer shell 1. At this time, the two mobile filter screens 8 will separate from each other, and the ferrous sulfate crystals on the two mobile filter screens 8 will fall from between the two mobile filter screens 8 into between the crystallization bin 5 and the annular filter screen 14, and fall from the gap between the drainage block 15 and the annular filter screen 14 and pass through the discharge pipe 3. After the ferrous sulfate crystals are separated from the solution, the ferrous sulfate crystals are directly collected without manual collection, thereby shortening the operation time and improving work efficiency.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
