Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an online monitoring impurity filtration tank at the front end of water sampling. Background Technology

[0002] Online monitoring systems typically detect a high level of impurities in the incoming water. When domestic sewage is discharged, the water may contain some grease. Furthermore, the water sampling pipe of the online monitoring equipment is relatively thin. This makes it easy to collect impurities, which can lead to blockages in the sampling pipe or central parts of the equipment, affecting normal sampling. Excessive blockage frequency can even shorten the equipment's lifespan. Secondly, the presence of grease can easily result in abnormally high levels, failing to reflect the true water quality.

[0003] Most existing filters use a screen filter. On the one hand, the influent water medium is complex, making it difficult to accurately select the screen mesh size. If the screen mesh size is too low, the filtration effect is poor. If the screen mesh size is too high, there is too much filtration medium, which leads to the data being too low and cannot reflect the true water quality. On the other hand, the screen filter is easy to clog, making it relatively inconvenient to use. Utility Model Content

[0021] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] As a preferred embodiment of this utility model, see attached... Figure 1As shown in the figure, this embodiment provides an online monitoring water intake front-end impurity filtration tank, including a tank body 1. The tank body 1 has an inlet 2 on its first side and an outlet 3 on the top of its second side. The inlet 2 is located in the middle of the tank body 1. A downwardly extending baffle 4 is connected to the top of the tank body 1. An upwardly extending flow-slowing plate 5 is provided at the bottom of the tank body 1. The flow-slowing plate 5 is located downstream of the baffle 4. A sand discharge port 6 is provided at the bottom of the second side of the tank body 1.

[0023] It should be noted that the first side and the second side referred to in this utility model are two opposite sides, namely the water inlet side and the water outlet side.

[0024] In the above embodiment, based on the physical properties of different impurities' specific gravities, when water enters the tank, grease, being lighter than water, floats to the surface under gravity, while the water sinks to the bottom. At this point, three zones are formed in the tank: the upper layer is grease floating on the surface; the middle layer is a mixed liquid containing suspended particles; and the bottom layer is relatively clean water. The built-in baffles further intercept pollutants, while the relatively clean water at the bottom flows downstream, thus achieving the purpose of purifying wastewater. Grease can be cleaned from the top of the tank, and sediment can be discharged by closing the outlet and opening the sand discharge port. The sand discharge port 6 precisely discharges sediment and sand from the bottom of the tank, preventing accumulation and blockage of the flow channel, reducing the frequency of manual dredging, and ensuring long-term stable operation of the equipment.

[0025] In some embodiments, an oil drain port 7 is further provided on the first side of the tank body 1, and the oil drain port 7 is located above the water inlet 2. Unlike the first embodiment, this embodiment provides an oil drain port 7 above the water inlet 2, so the oil can be quickly discharged by opening the oil drain port without having to clean and discharge it from the top of the tank body 1, reducing the difficulty of diversion. The oil drain port 7 utilizes the characteristic that oil is "lighter than water and floats easily" to accurately collect surface oil, achieving preliminary separation of the oil-solid-water three phases, providing a cleaner water sample for subsequent online monitoring, and reducing the interference of impurities on the monitoring equipment.

[0026] In some preferred embodiments, the pool body 1 is provided with two baffles 4, and a flow-slowing plate 5 is provided downstream of each baffle 4. Both the baffles 4 and the flow-slowing plates 5 are vertically arranged. This embodiment, by configuring multiple baffles, forms a "stepped" separation, with each stage able to trap impurities of different particle sizes, significantly improving the solid-liquid separation efficiency.

[0027] In another embodiment, such as Figure 2As shown, unlike the above embodiment, both the baffle 4 and the flow-slowing plate 5 are inclined towards the water outlet direction, forming an angle of 15°-45° with the vertical plane. The inclined baffle and flow-slowing plate optimize the water flow pattern and enhance the separation effect. The inclined design of the baffle and flow-slowing plate allows the water flow to form an "oblique flow" shape: compared with the vertical setting, the inclined structure can guide the water flow to form a "spiral / wall-adhering flow", increasing the contact opportunity between impurities and the pool wall and plate, and enhancing the sedimentation effect; the inclined angle can be reduced to accelerate the flow of high-sand water, while the inclined angle can be increased to prolong the residence time of low-turbidity water, flexibly adapting to various water intake scenarios.

[0028] In some preferred embodiments, a removable cover plate 8 is provided on the top of the tank for easy cleaning and inspection. A lifting lug 9 is also provided on the cover plate 8 to facilitate opening. The removable cover plate and lifting lug facilitate equipment maintenance and cleaning, ensuring the continuous and stable operation of the filtration tank.

[0029] In some preferred embodiments, of the two baffles 4, the end of the downstream baffle 4 is located below the end of the upstream baffle. The tops of the two flow-damping plates 5 are located above the bottom end of at least one of the baffles 4.

[0030] In the above embodiments, the lateral distance between the flow-damping plate 5 and the partition plate 4 is between 60cm and 120cm. In practical applications, the distance between the flow-damping plate 5 and the partition plate 4 can be adjusted according to factors such as the quality of the influent water and the size of the pool.

[0031] This invention constructs a multi-stage separation process by combining baffles and flow-damping plates:

[0032] After water enters the inlet, the baffle creates an initial sedimentation space, where large particles of silt settle rapidly due to the reduced flow velocity.

[0033] After the water flows over the baffle, the flow-slowing plate further disrupts the flow pattern and prolongs the hydraulic residence time, allowing fine silt and suspended matter to settle fully.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
