[0024] (1) By arranging a filter media mechanism, the precipitated substances are continuously filtered by the equally-angled arranged material cylinders, and the clarified liquid after filtration is collected through a hopper.

[0025] (2) By setting up a feeding component, with the driving effect of the conveyor belt and the driving wheel, when stirring and neutralizing the waste liquid, the rotating rod drives the auger to rotate, so as to convey the solution containing sediment to the inside of the cylinder through the feeding pipe for circulating filtration, so as to directly treat the sediment during the neutralization treatment, thereby improving the treatment efficiency and reducing the treatment cost.

[0026] (3) By setting up a pressure reduction unit, when the cylinders are rotated to receive materials, due to the increase in the hydraulic pressure inside the 1 feeding pipe, the plug is pushed into the inside of the sleeve, disengaging from the occlusion of the pressure reduction port, so that the conveyed solution flows back into the inside of the box through the pressure reduction port, avoiding problems such as equipment damage and reduced sealing caused by the increase in internal pressure.

[0027] (4) By setting up a blanking component, with the ring pressing against the cross bar, the filter plate is in a horizontal state to seal the bottom end of the cylinder, realizing the filtration of the sediment, and the setting of the groove provides space for the rotation of the cross bar, so that the filter plate is disengaged from the occlusion, facilitating the discharge of the sediment after pressure filtration inside the cylinder.

[0028] (5) By setting up a material cleaning unit, when the filter plate rotates for blanking, the lifting rod drives the cleaning rod into the inside of the cylinder, and through the drive of the rotating motor, the cleaning rod sweeps the inside of the cylinder, enabling the completely discharged sediment after pressure filtration, and through the connection of the suction hood and the suction pipe with an external negative pressure device, the sediment can be negatively absorbed.

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-6 , the present invention provides a technical solution: a neutralization device for treating sulfur-containing waste liquid:

[0038] Embodiment 1: Refer to the attached drawings of the specification Figure 1 and the attached Figure 2 ;

[0039] It includes a box body 1. Inside the box body 1, there is a stirring shaft, which is made from the stirring device inside the tank body in an existing industrial waste liquid neutralization device. Inside the box body 1, there is a filter media mechanism. The filter media mechanism includes a fixed rod 2, the outer surface of the fixed rod 2 is fixedly connected to the inside of the box body 1, and the outer surface of the fixed rod 2 is rotatably connected through a material tray 3. There is an axial limiting measure for the connection between the material tray 3 and the fixed rod 2. The body of the material tray 3 is fixedly connected through a material cylinder 4. Below the material cylinder 4, there is a hopper 7, which can be used for storing filtered clear liquid, and the discharge end can be connected to a spraying device. The spraying device can be arranged above the inside of the box body 1 for flushing after discharging the materials inside the box body 1. The body of the hopper 7 is provided with a through overflow hole 8, and the overflow hole 8 can overflow the excess filtered clear liquid. Outside the hopper 7, there are two fixed plates 9, the outer surfaces of both fixed plates 9 are fixedly connected to the inside of the box body 1, and the bodies of both fixed plates 9 are rotatably connected through ratchets 10. The ratchet 10 is composed of a rotating shaft and a housing. There is an axial limiting measure between the housing and the rotating shaft, and there is a ratchet structure between the housing and the rotating shaft. At the same time, the body of the rotating shaft is provided with a coaxial through connecting hole, and the inner wall of the connecting hole is provided with a through spiral groove. The outer surface of the hopper 7 is fixedly connected with two connecting rods 11. The middle part of the connecting rod 11 is provided with a spiral part. The other outer diameter dimensions of the connecting rod 11 are adapted to the dimensions of the connecting hole on the rotating shaft of the ratchet 10. The spiral part is in spiral contact with the spiral groove, which can cause the rotating shaft to rotate. The outer surfaces of the two connecting rods 11 are respectively movably connected through the rotating shafts of the two ratchets 10. One end of each of the two connecting rods 11 is fixedly connected with a pressing plate 12, the outer surface of the pressing plate 12 is movably connected to the inside of the material cylinder 4. A compression spring 13 is sleeved outside the connecting rod 11. The compression spring 13 makes the hopper 7 reset through resilience. One end of the compression spring 13 is fixedly connected to the outer surface of the fixed plate 9, and the other end of the compression spring 13 is fixedly connected to a push plate 14. The body of the push plate 14 is fixedly connected through the outer surface of the connecting rod 11. The housing of the ratchet 10 is fixedly connected with a toothed ring 15, and the outer surface of the toothed ring 15 is meshed with the outer surface of the material tray 3.

[0040] In this embodiment, the solution containing the precipitated substance enters the interior of the cartridge 4 for filtration. The precipitated substance accumulates inside the cartridge 4, and the filtered clear liquid falls inside the hopper 7. After the overall gravity of the hopper 7 increases, it drives the connecting rod 11 and the pressing plate 12 to descend, and compresses the compression spring 13 through the pushing plate 14. When the connecting rod 11 continues to descend, the spiral part provided on its body makes a spiral abutment with the rotating shaft of the ratchet wheel 10. The rotating shaft of the ratchet wheel 10 idles without causing the rotation of the tray 3, so as to facilitate the stable receiving of the empty cartridge 4. Along with the continuous descent of the connecting rod 11, the pressing plate 12 enters the interior of the cartridge 4 for pressure filtration. At the same time, when the excess clear liquid inside the hopper 7 overflows and flows out through the overflow hole 8, after the gravity of the hopper 7 decreases, the compression spring 13 pushes the hopper 7 to rise and reset. During the reset process, the rotating shaft drives the outer shell and the toothed ring 15 to rotate through the pawl, and meshes with the teeth of the toothed ring 15 and the tray 3, so that the tray 3 drives the cartridge 4 containing the precipitated substance to move to directly below the pressing plate 12, so as to perform pressure filtration treatment when the pressing plate 12 descends again.

[0041] Embodiment 2: On the basis of Embodiment 1, refer to the attached drawings of the specification Figure 1 and attached Figure 3 ;

[0042] A feeding assembly 5 is arranged outside the cartridge 4. The feeding assembly 5 includes a feeding pipe 51. One end of the feeding pipe 51 is communicated with the top end of the cartridge 4. A fixing column 53 is fixedly connected to the outer surface of the feeding pipe 51. The outer surface of the fixing column 53 is fixedly connected to the interior of the box body 1. A screw conveyor 54 is rotatably connected to the interior of the feeding pipe 51. The screw conveyor 54 can also be replaced by an existing propeller to pump the solution by rotation. A ring plate 58 is movably connected to the outer surface of the feeding pipe 51. The body of the ring plate 58 is fixedly connected through the outer surface of the cartridge 4. One end of the screw conveyor 54 is fixedly connected to a rotating rod 55. The outer surface of the rotating rod 55 is rotatably connected through the body of the feeding pipe 51. A transmission belt 56 is sleeved outside the rotating rod 55. Two transmission wheels 57 are drivingly connected to the outer surface of the transmission belt 56. The bodies of the two transmission wheels 57 are respectively fixedly connected through the outer surfaces of the rotating rod 55 and the stirring shaft.

[0043] In this embodiment, when the stirring shaft stirs and neutralizes the solution, through the meshing of the transmission wheels 57 and the transmission belt 56, the rotating rod 55 drives the screw conveyor 54 to rotate, so as to pump the solution containing the precipitated substance inside the box body 1 into the interior of the cartridge 4 through the feeding pipe 51 for filtration. At the same time, when the precipitated substance inside the cartridge 4 increases, resulting in the outflow of the clear liquid inside the hopper 7 being greater than the inflow, the hopper 7 rises to drive the tray 3 to rotate. When the cartridge 4 moves and changes positions accordingly, one end of the feeding pipe 51 contacts the ring plate 58 for plugging and sealing.

[0044] Embodiment 3: On the basis of Embodiment 2, refer to the attached drawings of the specification Figure 3 and attachedFigure 4 ;

[0045] A pressure reducing unit 52 is provided on the body of the material conveying pipe 51. The pressure reducing unit 52 includes a sleeve 521. One end of the sleeve 521 is in through communication with the inside of the material conveying pipe 51. A through pressure reducing port 522 is provided on the body of the sleeve 521. The pressure reducing port 522 facilitates the solution to flow back into the inside of the box body 1. A plug 523 is slidably connected inside the sleeve 521. The plug 523 is made of a material with good sealing performance and blocks the pressure reducing port 522 when feeding materials inside the barrel 4. A telescopic rod 524 is fixedly connected to the outer surface of the plug 523. The telescopic rod 524 can be made of an existing spring rod to facilitate the reset of the plug 523. The outer surface of the telescopic rod 524 is fixedly connected to the inside of the sleeve 521. An air pipe 525 is in through communication with the inside of the sleeve 521. An air core can be arranged inside the air pipe 525 to fill high-pressure gas inside the sleeve 521 as a resistance to offset the hydraulic pressure and facilitate the reset of the plug 523. A nut 526 is threadedly connected to the outer surface of the air pipe 525.

[0046] In this embodiment, high-pressure gas is filled inside the sleeve 521 through the air pipe 525 as a resistance, and then the nut 526 is screwed on to protect the end of the air pipe 525. When one end of the material conveying pipe 51 contacts the ring plate 58, the internal hydraulic pressure increases, and the solution pushes the plug 523 to slide inside the sleeve 521, compressing the output end of the telescopic rod 524 and the high-pressure gas. When the plug 523 disengages from blocking the pressure reducing port 522, the solution inside the material conveying pipe 51 directly flows back into the inside of the box body 1 through the pressure reducing port 522. When the material conveying pipe 51 and the barrel 4 are in communication, the high-pressure gas and the output end of the telescopic rod 524 push the plug 523 to reset and continue to block the pressure reducing port 522.

[0047] Embodiment 4: On the basis of Embodiment 3, referring to the appended drawings of the specification Figure 1 and appended Figure 6 ;

[0048] An unloading assembly 6 is arranged outside the barrel 4. The unloading assembly 6 includes a filter plate 61. Filter holes are formed in the filter plate 61 to filter precipitated substances.

A folding plate 64 is rotatably connected through the outer surface of the cross bar 63. The outer surface of the folding plate 64 is fixedly connected to the outer surface of the barrel 4. A torsion spring 65 is sleeved on the outer surface of the cross bar 63. The torsion spring 65 is convenient for restricting the rotation amplitude of the cross bar 63 and for assisting the cross bar 63 to rotate and reset. Two ends of the torsion spring 65 are respectively fixedly connected to the folding plate 64 and the outer surface of the cross bar 63. A circular ring 66 is movably connected to the outer surface of the cross bar 63. The surface of the circular ring 66 abuts against the cross bar 63, so that the filter plate 61 remains horizontal for filtering precipitated substances. The ring hole of the circular ring 66 is fixedly connected to the outer surface of the fixed rod 2. A groove 67 is formed in the outer surface of the circular ring 66. Chamfers are arranged on both sides inside the groove 67 to facilitate the entry and exit of the cross bar 63. The outer surface of the cross bar 63 is movably connected to the inside of the groove 67.

[0049] In this embodiment, when the barrel 4 moves, the filter plate 61 is driven to move along with the movement through the folding plate 64 and the cross bar 63. At the same time, the surface of the cross bar 63 abuts against the surface of the circular ring 66, so that the filter plate 61 remains horizontal to filter precipitated substances and the precipitated substances are kept inside the barrel 4. After one side of the cross bar 63 enters the inside of the groove 67, the filter plate 61 rotates to disengage from the occlusion of the bottom of the barrel 4, so that the precipitated substances inside the barrel 4 are discharged.

[0050] Embodiment Five: On the basis of Embodiment Four, refer to the attached drawings in the specification Figure 1 and the attached Figure 5 and the attached Figure 6 ;

[0051] An emptying unit 62 is arranged outside the filter plate 61. The emptying unit 62 includes a rubber sleeve 621. By stretching, the rubber sleeve 621 can avoid the problem of sediment floating during emptying. At both ends of the rubber sleeve 621, a perforated plate 622 and a connecting plate 623 are respectively fixedly connected. The body of the perforated plate 622 is provided with a through annular hole, and the inner diameter of the annular hole is the same as the inner diameter of the material cylinder 4. When the two are vertically aligned and connected, the bottom of the perforated plate 622 is attached to the top of the material cylinder 4. The outer surface of the perforated plate 622 is fixedly connected to the inside of the box body 1. The inside of the rubber sleeve 621 is connected to the inside of the material cylinder 4 through the annular hole of the perforated plate 622.

The rotating motor 625 is electrically connected to an external control circuit. The outer surface of the rotating motor 625 is fixedly connected to the outer surface of the connecting plate 623. The output end of the rotating motor 625 is fixedly connected with a cleaning rod 626 through a coupling. The surface of the cleaning rod 626 is provided with bristles for sweeping and discharging sediment. The outer surface of the cleaning rod 626 is rotatably connected to the inside of the material cylinder 4. The body of the connecting plate 623 is fixedly connected with a one-way valve 627 in a penetrating manner. The one-way valve 627 can make the air inside the box body 1 flow into the inside of the rubber sleeve 621 unidirectionally, avoiding the problem that sediment is reversely sucked into the rubber sleeve 621 and the inside of the material cylinder 4 due to the action of air pressure difference when the cleaning rod 626 rises and resets. The inside of the one-way valve 627 is respectively connected to the inside of the box body 1 and the rubber sleeve 621. An air suction hood 628 is arranged outside the rubber sleeve 621. The air suction hood 628 is arranged below the filter plate 61. A suction pipe 629 penetrates and communicates inside the air suction hood 628. One end of the suction pipe 629 is connected to an external negative pressure device. The outer surface of the suction pipe 629 is fixedly connected to the body of the box body 1 in a penetrating manner.

[0052] In this embodiment, when the filter plate 61 rotates, the sediment inside the material cylinder 4 is discharged, and the air suction hood 628 receives it. At the same time, the external negative pressure device absorbs it through the suction pipe 629. At the same time, the output end of the lifting rod 624 extends, so that the connecting plate 623 drives the rotating motor 625 and the cleaning rod 626 to descend, and the cleaning rod 626 enters the inside of the material cylinder 4 through the action of the annular hole of the perforated plate 622. Then, the rotating motor 625 drives the cleaning rod 626 to rotate to sweep the sediment inside the material cylinder 4 to completely discharge the material.
