DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1-6As shown, a wastewater desulfurization device includes a desulfurization cylinder 1, a dividing device 2 and a first storage chamber 3, wherein the dividing device 2 is provided inside the desulfurization cylinder 1, and above the dividing device 2 is a first storage chamber 3 where sewage and desulfurization materials are mixed. It is characterized in that a sediment storage chamber 4 inside the purification cylinder 1 is placed below the dividing device 2, and the first storage chamber 3 is provided with a concentration detection device 6 to drive the dividing device 2 to divide the first storage chamber 3 and the sediment storage chamber 4, and the dividing device 2 drives the first discharge device 8 to discharge the mixture of sediment and liquid in the sediment storage chamber 4 to purify sulfide, and a liquid discharge replenishing device 7 is provided inside the first storage chamber 3 to control the liquid outlet 5 and the liquid inlet 9 to replace the liquid inside the first storage chamber 3.

[0024] Precipitated sulfide is produced by feeding wastewater and reactant into the first storage chamber 3 of the desulfurization cylinder 1 in equal proportion through a conveying device. The precipitated sulfide will enter the sediment storage chamber 4 through the dividing device 2. As the sulfur in the wastewater is extracted, the concentration of the liquid decreases. As the concentration of the liquid decreases, the buoyancy detected by the concentration detection device 6 decreases. The concentration detection device 6 will drive the dividing device 2 to close the connection between the first storage chamber 3 and the sediment storage chamber 4. At the same time, the first discharge device 8 is opened to discharge the precipitated sulfide and a certain amount of liquid in the sediment storage chamber 4 for purification. The reduction of liquid will reduce the energy used. At the same time, the dividing device 2 and the liquid discharge supplement device 7 cooperate to discharge the desulfurized wastewater from the liquid outlet 5. When the amount of wastewater in the first storage chamber 3 is less than a value, the liquid discharge supplement device 7 will close the liquid outlet 5 and release the closure of the liquid inlet 9, so that the wastewater and reactant are added to the first storage chamber 3. When the wastewater in the first storage chamber 3 comes to the previous position again, all devices that have changed their states are restored to their original states for the next desulfurization discharge.

[0025] Among them, Figure 1-6 As shown, the dividing device 2 includes a fixed disk 2-1, a first through hole 2-2, a rotating disk 2-3 and a second through hole 2-4. The fixed disk 2-1 is arranged inside the desulfurization cylinder 1, and the rotating disk 2-3 is arranged inside the fixed disk 2-1. The first through hole 2-2 is arranged on the fixed disk 2-1, and the second through hole 2-4 is arranged on the rotating disk 2-3. The concentration detection device 6 drives the rotating disk 2-3 to rotate to control whether the first storage chamber 3 and the sediment storage chamber 4 are connected. The rotating disk 2-3 drives the first discharge device 8 to discharge the sediment inside the sediment storage chamber 4.

[0026] Among them, Figure 1-6As shown, the concentration detection device 6 includes a mounting seat 6-1, a first float 6-2, a movable rack 6-3, a gear 6-4, a pulley group 6-5, a first bevel gear 6-6 and a second bevel gear 6-7. The mounting seat 6-1 is arranged on the fixed disk 2-1, the movable rack 6-3 slides on the mounting seat 6-1, the first float 6-2 is arranged on the movable rack 6-3, the movable rack 6-3 is meshed with the gear 6-4, the gear 6-4 is connected to the first bevel gear 6-6 through the pulley group 6-5, and the first bevel gear 6-6 is connected to the rotating disk 2-3 through the second bevel gear 6-7.

[0027] When the liquid concentration decreases, the density will also decrease, and then the buoyancy of the first float 6-2 will also weaken, and the first float 6-2 will move downward. The first float 6-2 drives the gear 6-4 to rotate through the moving rack 6-3, and the gear 6-4 drives the first bevel gear 6-6 and the second bevel gear 6-7 to rotate through the pulley group 6-5. The rotating second bevel gear 6-7 drives the rotating disk 2-3 to rotate.

[0028] Among them, Figure 1-6 As shown, the liquid discharge replenishing device 7 includes a mounting sliding cylinder 7-1, a movable disk 7-2, a limiting ball 7-3, a spring 7-4, a limiting groove 7-5, a connecting rod 7-6, a movable arc plate 7-7, a discharge hole 7-8, a baffle 7-9, a first connecting rod 7-10, a second float 7-11, a second connecting rod 7-12, a movable float 7-13 and a sealing plug 7-14, the mounting sliding cylinder 7-1 is arranged on the fixed disk 2-1, the movable disk 7-2 slides inside the mounting sliding cylinder 7-1, the mounting sliding cylinder 7-1 is provided with a limiting groove 7-5, two limiting balls 7-3 are arranged inside the movable disk 7-2, and two limiting balls 7-3 A spring 7-4 is provided in between, and the limiting groove 7-5 limits the movement of the movable disk 7-2 through the limiting ball 7-3. The movable arc plate 7-7 with the discharge hole 7-8 is connected to the movable float 7-13 through the connecting rod 7-6. The movable float 7-13 is arranged on the movable disk 7-2 through the first connecting rod 7-10. The movable arc plate 7-7 with the discharge hole 7-8 and the baffle 7-9 are arranged on the rotating disk 2-3. The second connecting rod 7-12 is arranged on the second float 7-11. The movable float 7-13 slides on the second connecting rod 7-12. The sealing plug 7-14 is arranged on the movable float 7-13. The sealing plug 7-14 controls the opening and closing of the liquid inlet hole 9.

[0029] The rotating rotating disk 2-3 drives the baffle 7-9 to rotate, so that the first storage chamber 3 is connected with the liquid outlet 5 through the discharge hole 7-8, and then the desulfurized liquid will be discharged outward through the liquid outlet 5. As the liquid level drops, the moving float 7-13 is no longer subject to buoyancy, and the moving float 7-13 will drive the sealing plug 7-14 to move downward a distance but will not detach from the liquid inlet 9 until the liquid level drops to the position of the second float 7-11. The second float 7-11 moves downward without the action of the float, and the second float 7-11 drives the moving float 7-13 and the sealing plug 7-14 to move again through the first connecting rod 7-10 until the second float 7-11 moves to the discharge hole 7-8 and the liquid outlet 5 and stops moving. At this time, the sealing plug 7-14 just detaches from the inside of the liquid inlet 9, and at the same time the limiting ball 7-3 enters the limiting groove 7-5 to limit the position of the movable disk 7-2 and the second float 7-11, and then the wastewater and the reactant are injected into the first storage chamber 3 through the liquid inlet hole 9. As the liquid level rises to the position of the movable float 7-13, the movable float 7-13 is acted upon by the buoyancy, and then the pressure on the second float 7-11 is reduced. The buoyancy of the second float 7-11 breaks through the force of the limiting ball 7-3 applied by the spring 7-4 on the limiting groove 7-5, and then the liquid discharge replenishing device 7 is reset. At the same time, the high-concentration liquid will also reset the concentration detection device 6 and reset the dividing device 2 to connect the first storage chamber 3 and the sediment storage chamber 4 again. At the same time, the reset first discharge device 8 of the rotating disk 2-3 disconnects the sediment storage chamber 4 from the outside again.

[0030] Among them, Figure 1-6 As shown, the first discharge device 8 includes a second rotating disk 8-1, a third through hole 8-2 and a fourth through hole 8-3. The second rotating disk 8-1 is arranged on the rotating disk 2-3 through a connecting rod, the third through hole 8-2 is arranged on the second rotating disk 8-1, and the fourth through hole 8-3 is arranged on the desulfurization cylinder 1 so that the outside and the sediment storage chamber 4 are connected. The first through hole 2-2 and the fourth through hole 8-3 correspond to each other up and down, and the third through hole 8-2 and the second through hole 2-4 are arranged at 90 degrees.
