Description

Technical Field

[0001] The utility model relates to a water decanter, in particular to a water decanter used for quickly discharging upper water of a muddy water natural drying field and a muddy water natural drying field. Background Art

[0002] The muddy water produced by the sedimentation tanks and filter tanks of some water plants is dried in the muddy water natural drying field. Figure 1 As shown, the mud and water natural drying field consists of a drying field pool 1, a filter layer 2, and a leachate recovery pipe 3. Its function is that part of the water in the mud and water 4 is filtered through the filter layer 2, and the filtered water is recovered through the leachate recovery pipe 3, and the other part of the water evaporates naturally into the air. Finally, the water is removed to achieve the effect of sediment drying. The mud and water natural drying field does not have complex mechanical dehydration equipment, does not require power supply or control equipment, has low investment, low operating costs, and is energy-saving and environmentally friendly. However, the natural drying speed is slow and the drying cycle is long.

[0003] Chinese patent document CN206693376U discloses a mobile siphon decanter for discharging supernatant from a mud drying pool. It includes a hose and a water intake head, a gate valve is arranged near the water outlet end of the hose, a floating block is arranged under the part of the hose inside the pool, and the water inlet end of the hose is connected to the water intake head; the water intake head has a hollow cavity, a curved pipe passes through the upper part of the cavity, and a floating ring is fixed around the periphery of the lower part of the cavity. One end of the curved pipe in the cavity opens vertically downward, and the other end of the curved pipe outside the cavity is connected to the water inlet end of the hose through a pipe clamp; one end of the curved pipe in the cavity is connected to a bottom valve and vertically downward, and an exhaust pipe with an exhaust valve is arranged on the curved pipe part in the cavity; a pull rope is tied at the upper end of the cavity. This patent can discharge the supernatant in time. However, since it does not have a weight-adjusting material, it can only float on the water surface. Once it touches the mud layer, it will no longer sink, and it cannot extract more water from the mud, and its water discharge capacity is weak. Utility Model Content

[0004] In view of the problems existing in the prior art, the technical problem to be solved by the utility model is to provide a decanter with adjustable weight, which can adjust the draft by adjusting its own weight, extract more water from the mud, enhance the water discharge capacity, and improve the drying efficiency of the mud and water natural drying field.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] In order to clearly describe the content of the utility model, this patent application uses the directional words "upper" and "lower" for distinction. The "upper" and "lower" are determined based on the layout orientation of the above drawings. When the actual use direction of the utility model changes, the directional designation changes accordingly, which cannot be regarded as a limitation on the scope of patent protection.

[0019] like Figure 2 As shown, the decanter with adjustable weight provided by the utility model comprises a buoyancy box 5, a retaining wall 6, a water injection port 7, a water discharge port 8, a drainage pipe water inlet 9, a drainage pipe water outlet 10, and an exhaust pipe 15; the buoyancy box 5 is a sealed box, the periphery of the top surface of the box extends upward from the retaining wall 6, a tube with a water injection port 7 and an exhaust pipe 15 connected to the inner cavity of the buoyancy box 5 is inserted in the middle of the top surface of the box, and a water discharge port 8 connected to the inner cavity of the buoyancy box 5 is provided at the bottom of the side of the box; the drainage pipe passes through between the top surface and the bottom surface or the side surface of the box, the drainage pipe water inlet 9 is flush with the top surface of the box, and the drainage pipe water outlet 10 is located below the bottom surface of the box or outside the side surface. A weir can be opened on the retaining wall 6 to facilitate water diversion.

[0020] like Figure 3 As shown, the utility model of the natural drying field of mud and water comprises a drying field pool body 1, a filter layer 2 is laid at the lower part of the drying field pool body 1, a leachate recovery pipe 3 is installed at the bottom of the filter layer 2, the filter layer 2 is filled with mud water 4, the above-mentioned decanter A with adjustable weight floats in the mud water 4, a wastewater recovery well 12 is arranged on one side of the drying field pool body 1, a water outlet hose 11 is connected between the drainage pipe outlet 10 of the decanter A and the reserved interface 13 on the partition wall of the wastewater recovery well 12, the outlet of the leachate recovery pipe 3 is connected to the wastewater recovery well 12, and a wastewater recovery pipe 14 is arranged on the bottom surface of the wastewater recovery well 12.

[0021] The working process of the weight-adjustable decanter of the utility model is:

[0022] The drainage port 8 of the decanter is blocked, and the muddy water 4 flows into the muddy water natural drying field. The liquid level gradually rises, and the decanter floats up due to the buoyancy of the float box 5. At this time, the muddy water cannot flow into the decanter A.

[0023] After a period of sedimentation, the clean water with lower density moves upward, and the muddy water with higher density sinks. The density of muddy water increases with the depth. At this time, water is manually injected into the float box 5 from the water inlet 3 of the decanter A, and the air is discharged from the exhaust pipe 15. The weight of the decanter increases and gradually sinks. When it sinks to the point where the weir on the upper part of the enclosure wall 6 is lower than the muddy water level, the supernatant flows over the enclosure wall 6 into the decanter A, and then flows into the wastewater recovery well 12 through the drainage pipe inlet 9, the drainage pipe outlet 10, the water outlet hose 11, and the reserved interface 13 of the wastewater recovery well, realizing the decanting function; at the same time, the seepage liquid from the filter layer 2 is collected through the leachate recovery pipe 3 and flows into the wastewater recovery well 12, and the supernatant and the seepage liquid are collected in the wastewater recovery well 12 and recovered through the wastewater recovery pipe 14.

[0024] As the supernatant flows out, the density of the muddy water 4 gradually increases, and the draft of the decanter A gradually decreases. When the draft is reduced to the level of the weir on the upper part of the enclosure wall 6 and the muddy water 4, the supernatant no longer flows into the decanter, and water is poured into the float box 5, and the decanter A sinks further, completing the decanting function again, until the float box 5 is filled with water, the decanter A no longer sinks, and no supernatant flows into the decanter A, and the decanting stops.

[0025] During the decanting process, the operator adjusts the weight of the buoy 5 by controlling the amount of water injected according to the mud content of the supernatant and the recovery standard of the supernatant to obtain different drafts. When the draft of the decanter A is large, the decanting speed can be accelerated or more supernatant can be decanted; when the draft of the decanter A is small, the decanting speed can be reduced or less supernatant can be decanted.

[0026] When the first decanting operation is completed, the blocked decanter drain port 8 is opened to release some water, and the next decanting operation can be prepared. When the decanter A needs to be moved to the spare water tank of the natural decanting field, all the water can be released through the drain port 8 to facilitate the transfer of the decanter.

[0027] The mud and water natural drying field of the utility model causes the water of the mud water 4 to infiltrate through the filter layer 2 and then collect it in the wastewater recovery well 12 through the leachate recovery pipe 3, and uses the decanter A to flow the supernatant of the mud water 4 from the water outlet hose 11 into the wastewater recovery well 12, thereby accelerating the water discharge speed of the mud water 4 and greatly improving the natural drying efficiency of the mud water.
