[0037] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are considered to be exemplary in nature rather than limiting.

[0038] In view of the prior art, since the discharge plate needs to maintain sustainable rotating action, the discharge plate and the valve body are not in complete contact, which leads to poor sealing effect of the discharge valve. Furthermore, with the rotation of the discharge plate, the discharge plate gradually separates from the gap of the valve body, so that the gap on the valve body is completely exposed, which leads to the problem that the titanium concentrate leaks to the outside of the discharge valve through the exposed gap during the discharge process.

[0039] As shown in Figures 1-6 , the titanium concentrate discharge valve provided by the embodiments of the present application comprises an upper valve body 1, a lower valve body 2, an upper sealing ring 3, a lower sealing ring 5, and a discharge plate 8.

[0040] As shown in Figures 3-4 , the upper valve body 1 is fixedly connected to the bottom end of a bin body (not shown in the figure), and has a through upper valve body cavity 11 inside, which corresponds to the inside of the bin body. An annular upper installation blind groove 12 is formed on the upper valve body 1. An upper connecting piece 13 is further provided on the outer side of the upper valve body 1 in the radial direction, and an upper connecting hole 14 is formed on the upper connecting piece 13.

[0041] As shown in Figures 1-4 , the lower valve body 2 is fixedly arranged on a support frame (not shown in the figure) and located below the upper valve body 1 with a certain gap 7 between the upper valve body 1. The lower valve body 2 has a through lower valve body cavity 21 inside, which corresponds to the upper valve body cavity 11. An annular lower installation blind groove 22 is formed on the lower valve body 2, which corresponds to the upper installation blind groove 12. A lower connecting piece 23 is provided on the outer side of the lower valve body 2 in the radial direction, and a lower connecting hole 24 is formed on the lower connecting piece 23, which corresponds to the upper connecting hole 14. A double-headed bolt 9 passes through the upper connecting hole 14 and the lower connecting hole 24 in sequence, thereby realizing the connection between the upper valve body 1 and the lower valve body 2.

[0042] As shown in Figure 3As shown, the upper sealing ring 3 is slidably arranged in the upper accommodating blind groove 12 by the upper springs 4 and is in contact with the wall of the upper accommodating blind groove 12. When the upper sealing ring 3 is in an unforced state, a part of the upper sealing ring 3 is located in the upper accommodating blind groove 12 and is in contact with the wall of the upper accommodating blind groove 12, and the other part of the upper sealing ring 3 protrudes from the upper accommodating blind groove 12 and is located outside the upper accommodating blind groove 12. When the upper sealing ring 3 is in a forced state, the position of the upper sealing ring 3 can change with the change of the force condition, that is, the position of the upper sealing ring 3 can be located in the upper accommodating blind groove 12 or a part of the upper sealing ring 3 is located in the upper accommodating blind groove 12 and the other part is located outside the upper accommodating blind groove 12.

[0043] As shown, Figures 3-4 the lower sealing ring 5 is slidably arranged in the lower accommodating blind groove 22 by the lower springs 6 and is in contact with the wall of the lower accommodating blind groove 22. The lower sealing ring 5 corresponds to the upper sealing ring 3 and is appropriately sized. When the lower sealing ring 5 is in an unforced state, a part of the lower sealing ring 5 is located in the lower accommodating blind groove 22 and is in contact with the wall of the lower accommodating blind groove 22, and the other part of the lower sealing ring 5 protrudes from the lower accommodating blind groove 22 and is located outside the lower accommodating blind groove 22 and is in contact with the part of the upper sealing ring 3 located outside the upper accommodating blind groove 12. At this time, the gap 7 between the upper valve body 1 and the lower valve body 2 is in a sealed state. When the lower sealing ring 5 is in a forced state, the position of the lower sealing ring 5 can change with the change of the force condition, that is, the position of the lower sealing ring 5 can be located in the lower accommodating blind groove 22 or a part of the lower sealing ring 5 is located in the lower accommodating blind groove 22 and the other part is located outside the lower accommodating blind groove 22.

[0044] As shown, Figure 1 the discharging plate 8 is slidably arranged on the stud bolt 9 and is located between the upper valve body 1 and the lower valve body 2 (that is, is located in the gap 7) and is in contact with or not in contact with the upper sealing ring 3 and the lower sealing ring 5. When the discharging plate 8 is in contact with the upper sealing ring 3 and the lower sealing ring 5, at this time, the upper sealing ring 3 and the lower sealing ring 5 are subjected to extrusion force, the upper springs 4 and the lower springs 6 are in a compressed state, the discharging plate 8 abuts against the upper sealing ring 3 and the lower sealing ring 5, and the sealing connection between the discharging plate 8 and the upper valve body 1 and the lower valve body 2 is realized through the upper sealing ring 3 and the lower sealing ring 5. When the discharging plate 8 is not in contact with the upper sealing ring 3 and the lower sealing ring 5, the upper springs 4 and the lower springs 6 are reset, the upper sealing ring 3 and the lower sealing ring 5 are reset and abut, the gap 7 between the upper valve body 1 and the lower valve body 2 is filled, and thus the sealing connection between the upper valve body 1 and the lower valve body 2 is realized.

[0045] Further, in order to improve the wear resistance of the discharging plate 8 and thus prolong the service life of the discharging plate 8, in the embodiment, the surface of the discharging plate 8 is coated with a ceramic coating, the material of the coating is WC-Co (tungsten carbide-cobalt) metal ceramic, the coating is prepared by using a supersonic flame spraying method, and the thickness of the coating is controlled to be 0.5-0.8 mm.

[0046] Furthermore, in order to reduce the flow resistance of titanium concentrate, reduce the resistance during the rotation of the unloading plate 8, and further improve the sealing performance of the gap 7, such as... Figure 6 As shown, the unloading plate 8 in this embodiment is wedge-shaped.

[0047] Furthermore, in order to mitigate the impact of titanium concentrate on the discharge plate 8, the titanium concentrate discharge valve also includes a distributor 10.

[0048] Specifically, such as Figure 4 As shown, the distributor 10 includes: a grid panel 101 fixedly disposed in the upper valve body cavity 11 and a plurality of distributing bodies 102 disposed on the grid panel 101.

[0049] The main material distribution body 102 is roughly ridge-shaped and extends along the direction of the silo.

[0050] Furthermore, to improve the service life of the dispensing body 102, the outer surface of the dispensing body 102 in this embodiment is covered with a wear-resistant coating containing microcapsules. When wear occurs on the outer surface of the dispensing body 102, the capsules rupture and release a repair agent. This repair agent undergoes a cross-linking and curing reaction when it encounters a catalyst in the coating, thereby repairing the worn surface.

[0051] In use, the titanium concentrate in the silo is first dispersed by its own weight through the distribution body 102 and falls onto the discharge plate 8 through the grid panel 101. At this time, since the discharge valve is closed, the discharge plate 8 exerts a compressive force on the upper sealing ring 3 and the lower sealing ring 5, causing the upper sealing ring 3 and the lower sealing ring 5 to abut against the discharge plate 8, thereby achieving a sealed connection between the discharge plate 8 and the upper valve body 1 and the lower valve body 2. When it is necessary to package the titanium concentrate, such as... Figure 5 As shown, the rotating unloading plate 8 controls the opening of the unloading valve, allowing titanium concentrate to pass through the lower valve body cavity 21 and enter the packaging bag under its own weight. During the rotation of the unloading plate 8, it gradually disengages from the upper sealing ring 3 and the lower sealing ring 5 (the compressive force on the upper and lower sealing rings 3 and 5 gradually disappears). At this time, the compressed upper spring 4 and lower spring 6 reset, pushing the upper sealing ring 3 and lower sealing ring 5 back into place, filling the gap 7 between the upper valve body 1 and the lower valve body 2, thus achieving a dynamic seal of the gap 7 and preventing the titanium concentrate from leaking out during unloading. When unloading the titanium concentrate is not required, the unloading plate 8 rotates in the opposite direction. During rotation, the unloading plate 8 gradually generates compressive force on the upper sealing ring 3 and lower sealing ring 5, while the upper spring 4 and lower spring 6 are compressed again. At this time, the unloading plate 8 and the upper and lower sealing rings 3 and 5 abut against each other again, thus ensuring a sealed connection between the unloading plate 8 and the upper and lower valve bodies 1 and 2.

[0052] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
