Description

Technical Field

[0001] The invention relates to the technical field of water distribution weir plates in water treatment projects, and in particular provides a manual water distribution weir plate. Background Art

[0002] In water treatment projects, it is often necessary to adjust the water volume of the front-end water in the treatment unit. This achieves the purpose of distributing water to each parallel treatment series at the next level according to different working conditions. Reasonable allocation of water to each treatment series is of practical significance for improving the operating effect and reducing energy consumption of sewage treatment plants. The water output and water level of the treatment series are usually controlled by the weir width and the water head on the weir. According to whether the weir top elevation is adjustable, it is divided into two categories: fixed weir and adjustable weir.

[0003] The fixed weir has a simple structure, but its disadvantage is that once installed, the height of the weir top cannot be adjusted during operation, which is not conducive to changing the water flow or water level through adjustment during operation.

[0004] The adjustable weir top plate can be lifted or rotated with the help of a driving device, which solves the shortcoming that the fixed weir top elevation cannot be adjusted. However, the shape of the weir top can only be a straight line, and the length of the weir top is also limited. When a long weir is required, multiple weirs need to be combined, which increases the difficulty of design, layout and manufacturing. In addition, the driving device is composed of mechanical parts such as motors, reducers, and screws, which require maintenance and repair during use, and the operating cost is relatively high. Long-term use of the weir plate will cause defects such as aging of rubber seals and wear and leakage of metal seals. In addition, due to the limitations of the weir gate structure and movement mode, the lifting and adjusting weir gate can only be used in occasions with a small weir top length. The swing-type adjustable weir gate has a small adjustment range of the water head on the weir and cannot be used in large-scale adjustment occasions.

[0005] Taking a sewage treatment plant as an example, sewage flows through the membrane grids in each channel along the direction of water flow and then is collected in the water collection channel. After the water flows into the water collection channel, it enters the water distribution channel separately. The water entering the water distribution channel has water volume requirements under the design conditions. In order to meet the requirements of water volume distribution, the conventional practice is to make the width of the water distribution channel into different sizes according to the demand for water distribution after hydraulic calculation, and set a manual electric adjustable weir plate at the water inlet of the water distribution channel to adjust the water inflow of different water distribution channels by opening and closing the weir plate. This method can theoretically achieve the function of regulating water volume, but in some special cases, when more diversified regulation of the water inflow of the water distribution channel is required, this design method cannot meet the requirements. For example, for water treatment projects constructed in multiple phases, it is necessary to coordinate the water volume allocation needs of each treatment series according to the near- and long-term operation scale. In addition, it is also necessary to dynamically adjust and match the difference between the water inflow scale and the design scale in each operation stage.

[0006] Therefore, based on the demand for diversified water volume regulation, it is urgent to invent a manual water distribution weir plate with simple structure, reliable effect and suitable for various operating conditions. Summary of the invention

[0038] See also Figure 1 , 3 As shown, the clamping plate 32 of the divided weir plate faces the pressure rod guide rail, and the front of the water retaining weir plate and the front of the regulating weir plate are the water-facing surfaces, see Figure 1 Water flow direction A; the block-type weir plate slides along the pressure rod guide rail to offset the thrust of the water flow.

[0039] See also Figure 1 As shown, a plurality of the segmented weir plates can be installed along the width of the water passage opening; the transverse water passage cross section of the water passage opening can be adjusted by increasing or decreasing the number of the segmented weir plates 3.

[0040] A cross bar 25 extends out from the upper end of the pressure rod guide rail along the water flow direction A.

[0041] See also Figure 3 As shown, the water retaining weir plate at the lower end of the pressure plate 22 is inserted into the reserved groove at the bottom of the water passage opening and fixed, and the pressure plate is fixedly connected to the embedded parts on the upper end surface of the reserved groove.

[0042] The water passage opening 1 is a water inlet opening or a water outlet opening.

[0043] The height of the regulating weir plate should be higher than the height of the horizontal liquid level of the water collection channel. The water passage 1 is a conventional civil engineering structure, which is surrounded by a top surface, two side walls and a bottom base; the fixed weir plate 2 is connected to the inner walls of the two side walls; and the guide long groove (11) is arranged on the top wall.

[0044] The present invention is mainly composed of a fixed weir plate and a block weir plate. The fixed weir plate is installed and fixed at the water inlet hole, and the block weir plate is composed of several blocks. When the hole needs to adjust the water inlet flow, the quick-type weir plate is manually inserted into the fixed weir plate. The block weir plate can be selected to insert several blocks according to the need to adjust the water volume, and the water inlet section width of the water inlet hole is guaranteed. This water inlet section width is the key to adjusting the water inlet volume.

[0045] In order to further explain the present invention, the operation steps of adjusting the water amount of the present invention are described in detail through the following examples.

[0046] Example

[0047] like Fig.10As shown, it is a schematic diagram of water distribution of water distribution channels in the prior art, with three water distribution channels 4 converging into a water collection channel 5, and five water distribution channel inlet holes 6 in the water collection channel 5. In the figure, the water flow direction A is shown. Fig.10 The five water diversion channels are numbered 1#-5#, and the distribution weir plate M of the present invention is applied to Fig.10 The sub-block weir plate 3 is respectively installed at the water inlet holes 6 of the five water diversion channels 1#-5#. The liquid level of the water outlet of the water collection channel 5 at the front end of the water inlet hole is horizontal. For example, when it is necessary to reduce the water inflow of the 1# water diversion channel, it is necessary to slide the sub-block weir plate 3 downward along the pressure rod guide rail 24 and plug it into the water retaining weir plate 21 of the fixed weir plate. Figure 2 , 3 As shown in the figure, several water diversion weir plates can be plugged in according to the requirements of water volume regulation. After the water diversion weir plates are plugged in, since the weir plate height of the water diversion weir plate is higher than the horizontal liquid level of the water collection channel, the water inlet section width of the water inlet of the 1# water diversion channel is changed. Compared with other water inlet openings without plugged-in block weir plates, the water inlet volume of this water inlet opening is changed. According to this principle, the water inlet section width of any water diversion channel can be changed at will, thereby changing the water inlet volume of the water diversion channel.

[0048] On the contrary, when the water inlet channel needs to increase the water inlet volume of a certain channel, the following operation can be performed. For example, if the water inlet volume of the 1# water diversion channel is to be increased, the block-type weir plate 3 needs to be plugged into the water diversion weir plates of the 2# to 5# water diversion channels, so that the water inlet cross-sectional width of the 2# to 5# water diversion channels will be reduced accordingly, and on the contrary, the water inlet volume of the 1# water diversion channel will be increased. The adjustment principle is based on the fact that the liquid level of the water collection channel is always horizontal, and then various throttling operations are performed on the 1# to 5# water diversion channels to achieve the water volume adjustment of the water diversion channels.

[0049] When regulating the water volume, in order to better meet the purpose of multi-proportional regulation, the width of the block-type weir plate 3 can be made into various specifications, so that the multi-proportional adjustment of the width of the water inlet section of the 1# to 5# water diversion channels can be met, thereby ensuring that the water inlet volume of the water diversion channel is controllable and reducing the impact of water volume errors.
