[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0019] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0020] Figure 1 A schematic diagram of a valve structure 100 for a chlorination furnace slag discharge tank according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the valve structure 100 includes: a bracket 10 for mounting above the overflow port 1 of the slag discharge tank; a valve 20 movably mounted on the bracket 10, the valve 20 having a first mating groove 22 and a second mating groove 24 located above the first mating groove 22; and a spring locking member 30 mounted on the bracket 10 and capable of lateral extension and retraction to lock or release the valve 20; when the spring locking member 30 engages with the first mating groove 22, the valve 20 is locked in a position where the overflow port 1 can be opened (at this time, the valve 20 is located above the overflow port 1 and has a gap between it and the overflow port 1); when the spring locking member 30 engages with the second mating groove 24, the valve 20 is locked in a position where the overflow port 1 can be closed.

[0021] In an embodiment of the present invention, the valve 20 can be locked in a position that allows the overflow port 1 to be opened or closed using the spring locking member 30. In this way, the overflow port 1 can be opened when an overflow operation is required, and the overflow port 1 can be closed after the overflow is completed, reducing the risk of molten salt spilling onto the ground when the slag discharge tank is hoisted.

[0022] In some embodiments, the bracket 10 includes two side portions (e.g., side plates) for being disposed on opposite sides of the overflow port 1, with the opposite side walls of the valve respectively abutting the two side portions. The valve 20 and the bracket 10 can be clearance-fitted, allowing the valve 20 to move along the side portion of the bracket 10. The bracket 10 can be constructed of angle steel and steel plates, and the valve 20 moves vertically within a groove in the upper part of the bracket 10.

[0023] In some embodiments, the support 10 is a cylindrical structure, the valve 20 is located inside the cylindrical structure and the sidewall of the valve 20 is close to the sidewall of the cylindrical structure. The valve 20 and the support 10 can be clearance-fitted, and the valve 20 can move along the sidewall of the support 10.

[0024] Mounting holes can be provided on the side or sidewall of the bracket 10, through which the spring locking member 30 passes to engage with the valve 20. When the spring locking member 30 engages with the first mating groove 22 or the second mating groove 24, the spring locking member 30 is in an extended state and abuts against the first mating groove 22 or the second mating groove 24, at which time the spring locking member 30 locks the position of the valve 20. When the spring locking member 30 engages with the part of the valve 20 other than the first mating groove 22 or the second mating groove 24, the spring locking member 30 is compressed and is in a retracted state, at which time the spring locking member 30 releases the valve 20.

[0025] In some embodiments, the number of first mating grooves 22, second mating grooves 24, and spring locking members 30 is at least two. At least two first mating grooves 22 and at least two second mating grooves 24 are respectively disposed on both sides of the valve 20, and at least two spring locking members 30 are disposed on both sides of the bracket 10. This allows for a more secure locking of the valve 20. At least two first mating grooves 22 can be at the same height, and at least two second mating grooves 24 can be at the same height. First mating grooves 22 and second mating grooves 24 located on the same side can be on the same vertical line.

[0026] In some embodiments, the valve 20 can be moved up and down by pulling and / or pressing. In some embodiments, the valve structure 100 further includes an operating handle 40 and a transmission rod 42. One end of the transmission rod 42 is connected to the operating handle 40, and the other end of the transmission rod 42 is connected to the valve 20 via a first hinge pin 44. The middle part of the transmission rod 42 is connected to the bracket 10 via a second hinge pin 46. The operating handle 40 can drive the transmission rod 42 to rotate around the second hinge pin 46 to move the valve 20 up and down. Thus, the valve 20 can be moved up and down by operating the operating handle 40. The second hinge pin 46 provides a fulcrum, and the first hinge pin 44 can convert force into a force that moves the valve 20 up and down. The second hinge pin 46 can be provided by a hinge support, which is mounted on the bracket 10 and connected to the transmission rod 42. The transmission rod 42 and the operating handle 40 can be different parts of a single rod.

[0027] The present invention also proposes a slag discharge device for a chlorination furnace, comprising: a slag discharge tank, a slag receiving tank, and a valve structure 100 according to any of the above embodiments. The inlet of the slag discharge tank is matched (e.g., aligned or connected) with the slag discharge port of the chlorination furnace, and the inlet of the slag receiving tank is matched with the overflow port 1 of the slag discharge tank. The valve structure 100 is disposed at the overflow port 1 of the slag discharge tank. The slag discharge tank and the slag receiving tank may have the same structure. The slag discharge tank is disposed at the upper end of a step and holds the slag material discharged from the chlorination furnace, while the slag receiving tank is disposed at the lower end of the step and holds the slag material overflowing from the slag discharge tank at the upper end of the step.

[0028] When the slag discharge tank begins to fill with high-temperature molten salt, the spring locking element 30 is engaged at the first mating groove 22 of the valve 20, and the valve 20 is in the open state. Once the molten salt reaches the overflow port 1, it begins to overflow from the overflow port 1. After overflow is complete, the valve 20 can be lowered and closed by pressing the valve 20 or moving the transmission rod 42. The spring locking element 30 then engages at the second mating groove 24 of the valve 20, locking the valve 20, and the slag discharge tank can then be hoisted.

[0029] In summary, by adding a valve structure to the overflow port of the slag discharge tank containing high-temperature molten salt, this invention can solve the problem of molten salt overflowing and flowing around the slag discharge tank, reduce the risk of molten salt spilling onto the ground during hoisting, and improve the production environment.

Within the framework of the invention, technical features of the above embodiments or different embodiments can be combined, and many other variations of the different aspects of the invention as described above exist, which are not provided in the details for the sake of brevity.
