Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation devices, in particular to a solid-liquid separation device used in a coagulation sedimentation primary sedimentation tank. Background Art

[0002] In municipal wastewater treatment plants, domestic sewage contains large amounts of suspended matter, such as paper scraps, silt, and food scraps. Coagulants are added to the sewage. Common coagulants include inorganic coagulants (such as aluminum sulfate, polyaluminum chloride, and iron salts) and organic polymer coagulants (such as polyacrylamide). Coagulants neutralize charges, form adsorption bridges, and compress the electrical double layer in water, destabilizing fine suspended particles and colloids, causing them to aggregate and form larger flocs (also known as coagulants or alum flocs). The flocs undergo solid-liquid separation, resulting in filtered water that can be further treated and discharged.

[0003] The basic principle of using a filter plate for filtering in a solid-liquid separation device is to increase the surface area of ​​contact between the water and the filter plate, thereby increasing the opportunity and space for suspended solids to settle and accelerating the sedimentation process. At the same time, filter holes are opened on the filter plate to allow water to drain out, thereby achieving solid-liquid separation. When using a filter plate to filter sewage, solids in the sewage are easily deposited on the filter plate, affecting the filtration efficiency. When treating sewage of different concentrations, the possibility of sediment in the sewage accumulating on the filter plate and causing blockage is also different. It is necessary to adjust the angle of the filter plate to reduce the risk of blockage. When the sewage flow falls directly on the filter plate, it will cause the water flow speed to be fast in some areas. The fast-flowing area may not allow the suspended solids to fully settle. For this reason, a solid-liquid separation device for a coagulation sedimentation primary sedimentation tank is proposed. Utility Model Content

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figure 1-Figure 4As shown, a solid-liquid separation device for a coagulation sedimentation primary sedimentation tank comprises an operating table 1, two electric push rods 2 are equidistantly fixedly connected to the bottom of the operating table 1, the lower output ends of the two electric push rods 2 are fixedly connected to a mounting plate, the top of the mounting plate is fixedly connected to a first motor 3, one side output end of the first motor 3 is fixedly connected to a first gear 4, the upper part of the first gear 4 is toothed with a second gear 5, the middle of the second gear 5 is fixedly sleeved with a transmission rod, both sides of the transmission rod are fixedly connected to a runner 6, the outer sides of the two runners 6 are equidistantly fixed with a number of impact blocks, two first limit plates are movably sleeved on the circumferential outer surface of the transmission rod, the lower parts of the two first limit plates are fixedly connected to the mounting plate, two second limit plates are equidistantly fixedly connected to the bottom of the operating table 1, and the two second limit plates are fixedly sleeved. The first limiting groove is provided on each of the two limiting plates, and the transmission rod passes through the two first limiting grooves. Through such an arrangement, the height of the runner 6 can be adjusted by the mounting plate when the electric push rod 2 is started. The different heights of the runner 6 affect the impact intensity. The transmission structure is driven by the first motor 3 to drive the runner 6 to rotate, so that the impact block on the runner 6 can continuously impact the impact plate 8, and the impact plate 8 then transmits the vibration to the filter inclined plate 13 to vibrate the filter inclined plate 13. Through such an arrangement, it is convenient to vibrate the filter inclined plate 13 so that the sediment on the filter inclined plate 13 is discharged, and the filter inclined plate 13 is prevented from being blocked, thereby improving work efficiency; the transmission rod is limited by the first limiting groove and can only move up and down, and the transmission rod then limits the runner 6 to only move up and down, so that the two runners 6 can vibrate synchronously.

[0030] like Figure 1-Figure 5 As shown, a working chamber is fixedly connected to the top of the operating table 1, and two first mounting plates are fixedly connected at equal distances on both sides of the working chamber. A spring 9 is fixedly connected to the top of the two first mounting plates on the same side, and an impact plate 8 is fixedly connected to the top of the two springs 9 on the same side. Through such an arrangement, the spring 9 is stretched by the impact plate 8 when the impact plate 8 is impacted. When the impact plate 8 is no longer impacted, the spring 9 drives the impact plate 8 to reset, thereby realizing the reciprocating motion of the impact plate 8 to form vibration.

[0031] like Figures 1-6 As shown, a mounting frame 10 is movably installed in the working chamber, and two mounting rods are fixedly connected to both sides of the mounting frame 10 at equal distances. Two second limit slots are opened at equal distances on both sides of the working chamber, and four mounting rods pass through the four second limit slots respectively. The two mounting rods on the same side are fixedly connected to the impact plate 8. Through such an arrangement, the second limit slot limits the mounting rod to move only up and down, and the mounting rod then limits the mounting frame 10 to move only up and down along the direction of the second limit slot.

[0032] like Figures 1-6As shown, a second mounting plate is fixedly connected to one side of the mounting frame 10, a second motor 11 is fixedly connected to the top of the second mounting plate, a rotating shaft 12 is fixedly connected to one output end of the second motor 11, mounting holes are provided on both sides of the mounting frame 10, and the rotating shaft 12 passes through the two mounting holes. Through such an arrangement, the second motor 11 can drive the rotating shaft 12 to rotate.

[0033] like Figures 1-6 As shown, the rotating shaft 12 is fixedly connected to a filter inclined plate 13 on the circumferential outer surface of the part inside the mounting frame 10, and both sides of the filter inclined plate 13 are fixedly connected to a limiting rod 14, and a third limiting groove is opened on both sides of the mounting frame 10, and the two limiting rods 14 pass through the two third limiting grooves respectively. Through such an arrangement, baffles are provided on both sides of the filter inclined plate 13 to prevent sewage from directly overflowing from both sides of the filter inclined plate 13 without undergoing solid-liquid separation; the third limiting groove can limit the limiting rod 14, so that the limiting rod 14 limits the filter inclined plate 13 to rotate only with the rotating shaft 12 as the axis; by starting the second motor 11, the rotating shaft 12 can be driven to rotate, and the rotating shaft 12 drives the filter inclined plate 13 to rotate with the rotating shaft 12 as the axis to adjust the angle of the filter inclined plate 13. Through such an arrangement, it is convenient to adjust the angle of the filter inclined plate 13 to meet the filtering requirements of sewage with different concentrations.

[0034] like Figure 1-Figure 3 、 Figure 8 As shown, a partition 15 is fixedly connected to the top of the operating table 1, and the outer side of the partition 15 is fixedly connected to the inner wall of the working chamber. A collecting box 16 is placed above the operating table 1, and one side of the collecting box 16 is against the partition 15. The collecting box 16 is positioned below the bottom of the filter inclined plate 13, and a movable groove is provided on the outside of the working chamber. One end of the collecting box 16 passes through the movable groove. Through such an arrangement, the sediment in the sewage after solid-liquid separation slides into the collecting box 16 under the action of gravity. A handle is installed on the outside of the collecting box 16, and the handle can pull the collecting box 16 to be taken out through the movable groove.

[0035] like Figure 1-Figure 3 、 Figure 7As shown, a water distribution tank 18 is fixedly connected to the top of the mounting frame 10, and the water distribution tank 18 is arranged above one side of the filter inclined plate 13, and a water inlet pipe 19 is fixedly connected to the top of the water distribution tank 18. The interior of the water distribution tank 18 is distributed in a pyramid shape and is fixedly connected to a plurality of water distribution plates 20. Through such an arrangement, when sewage enters the water distribution tank 18 through the water inlet pipe 19, the sewage is diverted through multiple water distribution plates 20, so that the sewage can fall evenly on the filter inclined plate 13. Through such an arrangement, the sewage is more evenly distributed on the filter inclined plate 13 and the sedimentation effect is improved; the shape of the water distribution plate 20 is an inverted V shape, and the design of the inverted V-shaped water distribution plate 20 can evenly disperse the water flow coming down from the water inlet pipe 19 to different areas of the filter inclined plate 13; when the water flows through the inverted V-shaped structure, it will be directed to both sides and then evenly distributed along the filter inclined plate 13, reducing the uneven water flow phenomenon that may be caused by direct impact.

[0036] like Figures 1-8 As shown, a water outlet pipe 7 is fixedly connected to one side of the working chamber, and a control panel 21 is fixedly connected to the other side of the working chamber. The control panel 21 is electrically connected to the electric push rod 2, the first motor 3 and the second motor 11. Through such an arrangement, the sewage after solid-liquid separation falls into the working chamber and is discharged through the water outlet pipe 7.

[0037] It should be noted that when in use, the operating table 1 is placed on a horizontal plane, sewage is added through the water inlet pipe 19, the sewage is diverted through the water diversion plate 20 in the water diversion tank 18 and falls on the filter inclined plate 13, the sewage is subjected to solid-liquid separation on the filter inclined plate 13, the water flow in the sewage is filtered on the filter inclined plate 13 and falls into the working chamber, the sewage is discharged from the outlet pipe 7, and the flocculent solids deposited on the filter inclined plate 13 slide into the collection box 16 under the action of gravity, and the collection box 16 can be pulled out through the movable groove by the handle.

[0038] When the flocculated solids on the filter inclined plate 13 are clogged, the electric push rod 2 is started through the control panel 21. The electric push rod 2 can drive the transmission rod to move upward through the mounting plate and the first limit plate, and the transmission rod can drive the runner 6 to move. The first motor 3 is started through the control panel 21. The first motor 3 drives the runner 6 to rotate through the first gear 4, the second gear 5 and the transmission rod. The runner 6 drives the impact block to hit the impact plate 8. The impact plate 8 drives the filter inclined plate 13 to move upward through the mounting rod, the mounting frame 10 and the rotating shaft 12. At the same time, the impact plate 8 drives the spring 9 to stretch. When the impact block no longer hits the impact plate 8, the spring 9 contracts and drives the filter inclined plate 13 to reset, thereby realizing the vibration of the filter inclined plate 13, so that the flocculated solids on the filter inclined plate 13 are discharged by gravity.

[0039] When solid-liquid separation is required for sewage of different concentrations, the second motor 11 is started to drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the filter inclined plate 13 to rotate around the rotating shaft 12 to adjust the angle of the filter inclined plate 13.

[0040] The utility model relates to the technical field of solid-liquid separation devices, and provides a solid-liquid separation device for a coagulation sedimentation primary sedimentation tank. The utility model solves the problem that when sewage is filtered using a filter inclined plate 13, solids in sewage are easily deposited on the filter inclined plate 13, affecting the filtration efficiency. When treating sewage of different concentrations, the possibility of sediment in the sewage accumulating on the filter inclined plate 13 and causing blockage is also different. It is necessary to adjust the angle of the filter inclined plate 13 to reduce the risk of blockage. When the sewage flow falls directly on the filter inclined plate 13, it will cause the water flow speed in some areas to be fast, and the fast-flowing area may not allow the suspended solids to be fully settled. The utility model is more practical.
