Summary of the invention

At the same time, an anti-splashing assembly is installed in the centrifugal assembly, which can close the top opening of the centrifugal bin during the centrifugal separation operation to prevent secondary splashing of wastewater during the centrifugal separation operation.

[0015] (2) The present application improves the stirring effect by providing a stirring component. The stirring component rotates under the control of a rotary rod and a rotating motor. Once the viscosity of the sewage is high, the pressure plate will be squeezed, and the plug rod fixed thereon will push the L-shaped clip rod to move.

[0043] Example 1

[0044] See also Figure 1-Figure 4The present embodiment provides a wastewater treatment device for the production of gypsum board face paper, comprising a mixing bin 100, a water pump 200 is mounted on the top of the mixing bin 100 through a bracket, a first rotating motor is mounted on the bottom of the mixing bin 100, a rotating rod 400 fixed on the output shaft of the rotating motor is arranged inside the mixing bin 100, three groups of stirring components 500 for enhancing the mixing effect are arranged in a circular shape in the middle of the outer side of the rotating rod 400, a flocculant adding component 600 is arranged on the side wall of the mixing bin 100, and a centrifugal component 300 is mounted on the side of the mixing bin 100 through a bracket;

[0045] The centrifugal assembly 300 includes a centrifugal chamber 310 fixed to the outside of the mixing chamber 100 by a bracket, a sewage pipe 320 connected to the water inlet of the water pump 200 is installed at the bottom of the centrifugal chamber 310, and a centrifugal drum 330 is rotatably connected inside the centrifugal chamber 310. The centrifugal drum 330 is an open hollow cylindrical structure with a plurality of holes for discharging sewage. A first connecting rod 340 is fixed inside the centrifugal drum 330, a splash-proof assembly 350 is fixed at the top of the first connecting rod 340, and a second connecting rod 360 is fixed at the top of the splash-proof assembly 350. A second rotating motor is installed at the top of the centrifugal chamber 310 through a bracket, and the output shaft of the second rotating motor is connected to the second connecting rod 360 through a transmission belt 370. 0 transmission connection, the anti-splashing assembly 350 includes a hollow shell 351 fixed between the first connecting rod 340 and the second connecting rod 360, a six-channel track block 352 is fixed inside the hollow shell 351, six centrifugal sliders 353 are slidably connected inside the six-channel track block 352, and six groups of first movable rods 354 are rotatably connected to the outer wall of the hollow shell 351. The centrifugal sliders 353 will slide toward the first movable rods 354 under the action of centrifugal force, thereby pushing the first movable rods 354 to rotate, and an elastic waterproof cloth 355 is installed between each first movable rod 354. When the first movable rod 354 rotates, the elastic waterproof cloth 355 will be unfolded to close the top of the centrifugal chamber 310 to prevent the sewage from splashing again.

[0046] When the above-mentioned device is in operation, the mixed sewage is first put into the centrifugal drum 330 in the centrifugal bin 310, and then the second rotating motor is started to drive the second connecting rod 360 to rotate through the transmission belt 370, and the second connecting rod 360 drives the first connecting rod 340 to rotate through the centrifugal assembly 300, and the first connecting rod 340 drives the centrifugal drum 330 to rotate. Under the action of centrifugal force, solid impurities in the mixed sewage will remain in the centrifugal drum 330, and the sewage will flow into the centrifugal bin 310 after passing through the centrifugal drum 330, and then the sewage will be sent to the mixing bin 100 through the water pump 200 for subsequent treatment;

[0047] While the centrifugal separation operation is being performed, in order to prevent the sewage from splashing out through the centrifugal chamber 310 for the second time during the centrifugal separation operation, during the rotation of the centrifugal assembly 300, under the action of centrifugal force, the first movable rod 354 in the hollow shell 351 will slide toward the first movable rod 354, thereby pushing the first movable rod 354 to rotate, and an elastic waterproof cloth 355 is installed between each first movable rod 354. When the first movable rod 354 rotates, the elastic waterproof cloth 355 will be unfolded to close the top of the centrifugal chamber 310 to prevent the sewage from splashing out for the second time.

[0048] In order to improve the mixing efficiency of flocculants and sewage, thereby accelerating the precipitation of impurities in sewage, see Figure 1 , Figure 5-Figure 11 The stirring assembly 500 in the present application includes a stirring rod 510 and a pressure plate 540. A first elastic rubber sleeve 520 is fixed to the inner top of the stirring rod 510. A top rod 530 is slidably connected to the stirring rod 510. The top rod 530 is an umbrella-shaped structure as a whole, and its top and both sides are arc-shaped structures. The setting of the umbrella-shaped structure can make the top of the stirring rod 510 have a double inclined surface setting when the first elastic rubber sleeve 520 is lifted up and deformed. A plurality of springs are fixed between the top rod 530 and the inner wall of the stirring rod 510. A groove 531 is provided at the bottom of the top rod 530. Both sides of the inner wall of the groove 531 are provided with card slots 532. A fixing block 57 is fixed to the bottom of the inner wall of the stirring rod 510 0, a limiting slide bar 590 is passed through and fixed in the middle of the fixed block 570, and both ends of the limiting slide bar 590 are passed through and slidably connected with an L-shaped snap rod 580, a spring is fixed between the L-shaped snap rod 580 and the fixed block 570, the pressure plate 540 is connected to the outside of the stirring rod 510 through the second elastic rubber sleeve 560, and two insertion rods 550 are fixed on the pressure plate 540, the front end of the insertion rod 550 is arranged in an inclined surface, the insertion rod 550 fits the side of the L-shaped snap rod 580, and the L-shaped snap rod 580 is pushed out of the slot 532 by the movement of the insertion rod 550, thereby releasing the limiting effect on the top rod 530, so that it can quickly rebound and reset under the action of the spring. The stirring effect is improved by providing a stirring assembly 500. The stirring assembly 500 rotates under the control of the rotary rod 400 and the rotary motor. Once the sewage has a high viscosity, the pressure plate 540 will be squeezed, and the plug rod 550 fixed thereon will push the L-shaped snap rod 580 to move. At this time, the L-shaped snap rod 580 disengages from the slot 532. Under the action of the spring, the top rod 530 will move upward rapidly, pushing the first elastic rubber sleeve 520 to deform, so that the top end of the stirring rod 510 is set with double inclined surfaces, which can form a spiral stirring effect, guide the lower sewage upward, improve the mixing efficiency of the flocculant and sewage, and thus accelerate the precipitation of impurities in the sewage.

[0049] The side of the mixing bin 100 is equipped with a transparent acrylic plate 700, and the side of the transparent acrylic plate 700 close to the inside of the mixing bin 100 is rotatably connected to the second movable rod 710, and a semi-cylindrical pressing block 720 is fixed to one side of the second movable rod 710, and an arc rod 730 is fixed to the other side of the second movable rod 710. After the equipment is finished working, the arc rod 730 is pushed to make the second movable rod 710 drive the semi-cylindrical pressing block 720 to rotate. At this time, the stirring component 500 in the rotating process will be squeezed by the semi-cylindrical pressing block 720, and the extrusion force will move the top rod 530 downward, and the top rod 530 is positioned again by the card slot 532 at the bottom of the top rod 530 in cooperation with the L-shaped buckle rod 580, so that the equipment is restored to the initial state.

[0050] When the stirring assembly 500 is actually working, after the sewage is sent into the mixing bin 100 through the water pump 200, the output shaft of the rotating motor drives the rotary rod 400 to rotate, and then the rotary rod 400 drives the stirring rod 510 to rotate. During the rotation of the stirring rod 510, once the viscosity of the sewage is too high, the pressure plate 540 on the side of the stirring rod 510 will be squeezed, and the plug rod 550 fixed thereon will push the L-shaped buckle rod 580 to move. At this time, the L-shaped buckle rod 580 is separated from the slot 532. Under the action of the spring, the top rod 530 will move upward quickly, pushing the first elastic rubber sleeve 520 to deform, so that the top of the stirring rod 510 is set with double inclined surfaces, which can form a spiral stirring effect, guide the lower sewage upward, improve the mixing efficiency of the flocculant and sewage, and thus accelerate the precipitation of impurities in the sewage;

[0051] It is worth noting that after the device is finished working, the arc rod 730 is pushed to make the second movable rod 710 drive the semi-cylindrical pressing block 720 to rotate. At this time, the stirring assembly 500 in the rotating process will be squeezed by the semi-cylindrical pressing block 720, and the ejector rod 530 is moved downward by the squeezing force. The ejector rod 530 is positioned again by the clamping groove 532 at the bottom of the ejector rod 530 in cooperation with the L-shaped clamping rod 580, so that the device is restored to the initial state;

[0052] Since there are two pressure plates 540 in a single stirring component 500 in the present application, and they are symmetrically arranged, no matter whether the rotation direction of the output shaft of the rotating motor is clockwise or counterclockwise, the stirring component 500 has a pressure plate 540 that is compatible with its rotation direction to sense the pressure direction, and the top of the stirring rod 510 is arranged with double inclined surfaces in the above manner, which can form a spiral stirring effect, guide the lower layer of sewage upward, improve the mixing efficiency of the flocculant and sewage, thereby accelerating the precipitation of impurities in the sewage, and ensure that the stirring component 500 can produce a diversion effect regardless of whether it rotates clockwise or counterclockwise.

[0053] In order to ensure that the flocculant and sewage can be mixed fully, see Figure 1 , Figure 5 , Fig.12 , which is achieved by setting a flocculant adding component 600 for intermittently spraying flocculants, wherein the flocculant adding component 600 includes a flocculant storage tank 610, a rectangular pipe 620, a disc-shaped nozzle 630, and a connecting block 690, wherein the flocculant storage tank 610 is fixed to the outside of the mixing bin 100, and the entire flocculant storage tank 610 is made of a transparent material, and a feeding port for adding flocculants is provided at the top thereof, and the bottom of the flocculant storage tank 610 is connected and fixed with a first pipe 64 0, and at the same time, the disc-shaped nozzle 630 is rotatably connected to the top of the rotating rod 400, and the top of the disc-shaped nozzle 630 is connected and fixed with a second pipe 660. Furthermore, the rectangular pipe 620 is fixed in the side wall of the mixing chamber 100, and one end of the rectangular pipe 620 is connected to the second pipe 660 through a one-way valve 1 670. The conducting direction of the one-way valve 1 670 is from the rectangular pipe 620 to the second pipe 660, and the other end of the rectangular pipe 620 is connected to the second pipe 660 through a one-way valve 2 650. The first pipe 640 is connected, and the conducting direction of the second one-way valve 650 is from the first pipe 640 to the rectangular pipe 620. The bottom of the rectangular pipe 620 is fixed with an elastic extrusion capsule 680. When the elastic extrusion capsule 680 is squeezed, the flocculant in the rectangular pipe 620 is squeezed into the second pipe 660 through the one-way valve 1 670. When the elastic extrusion capsule 680 rebounds and resets, the flocculant in the first pipe 640 is sucked into the rectangular pipe 620 through the one-way valve 2 650. , so that the rectangular pipe 620 is always in a saturated state, the connecting block 690 is fixed on the inner wall of the mixing bin 100, and the connecting block 690 is internally slidably connected with an extrusion rod 691, and the sliding resistance between the extrusion rod 691 and the connecting block 690 is greater than the static friction between the extrusion rod 691 and the connecting block 690, the top of the extrusion rod 691 is a disc-shaped structure, and the bottom of the extrusion rod 691 is a spherical structure, and the spherical structure at the bottom of the extrusion rod 691 is located on the movement path of the stirring rod 510.

[0054] When the flocculant adding assembly 600 is actually working, the bottom spherical structure of the extrusion rod 691 is squeezed by the rotation of the stirring rod 510, so that the extrusion rod 691 moves upward. At this time, the disc-shaped structure at the top of the extrusion rod 691 squeezes the elastic extrusion capsule 680. When the elastic extrusion capsule 680 is squeezed, the flocculant in the rectangular pipe 620 is squeezed into the second pipe 660 through the one-way valve 670. Then, the flocculant passing through the second pipe 660 is sprayed out through the disc-shaped nozzle 630. Since the contact time between the stirring rod 510 and the extrusion rod 691 is very short, the extrusion rod 691 squeezes the elastic extrusion capsule 680. The time for pressing the sac 680 is also very short, so after the elastic extrusion sac 680 is separated from the extrusion rod 691, it will reset under the action of its body rebound force. While the elastic extrusion sac 680 is reset, the flocculant in the first pipe 640 is sucked into the rectangular pipe 620 through the one-way valve 650, so that the rectangular pipe 620 is always in a saturated state. Therefore, the extrusion rod 691 is cyclically and intermittently squeezed by the three stirring rods 510, so the flocculant sprayed through the above steps will also be intermittently sprayed. The intermittently sprayed flocculant can be better mixed with the sewage, further improving the precipitation rate of impurities in the sewage.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
