[0002] As a core water priming device for pumps, the siphon water tank is designed based on the siphon principle and related fluid mechanics laws. It is widely used in agricultural irrigation, sewage treatment, industrial water conveyance and other scenarios. Its core function is to solve the problem of "low water, high pump" priming for pumps without self-priming function, and to ensure stable pump start-up and continuous water supply.

[0003] However, existing siphon water tanks still have significant shortcomings in practical applications, especially in municipal sewage lifting pump station scenarios. In these scenarios, sewage contains impurities of different particle sizes, such as household waste fragments, silt particles, and fibers. It is necessary to protect the pump body through graded filtration and to analyze the sewage concentration by relying on the proportion of impurities. However, in existing technologies, the bar screen is usually inserted into the tank, which makes it difficult to distinguish the content distribution and morphological characteristics of impurities of different particle sizes, and makes it difficult to trace the fluctuation of water source quality through impurity characteristics.

Detailed Implementation

[0018] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Reference Figure 1 - Figure 7 This utility model provides a grid-type siphon water tank, whose basic components mainly include a tank body 100. The liquid storage cavity 200 inside the tank body 100 is the core space for realizing siphon and filtration. The upper and lower parts of the tank body 100 are respectively provided with an inlet pipe 101 and an outlet pipe 102 (the inlet pipe 101 is located above the outlet pipe 102). Both are connected to the liquid storage cavity 200, forming the inlet and outlet path of water flow.

[0020] Specifically, four sets of inclined grid plates 300 are installed inside the liquid storage cavity 200. Adjacent grid plates 300 are fixedly connected by arc-shaped plates 301. The arc-shaped plates 301 are adapted to the inner wall of the tank body 100, which not only allows the grid plates 300 to stably fit the tank body 100, but also encloses an independent filtration space 400 between adjacent grid plates 300. Limiting plates 302 are also provided on the grid plates 300, which are connected to the positioning parts 700 (including the first limiting hole 700) on the top cover 600 of the tank body 100. 01. The second limiting hole 702) can be used to switch the work position of the grating plate 300. At the same time, the first connecting flange 500 on the top of the tank 100 and the second connecting flange 601 on the top cover 600 are fixed by locking bolts 800. The sealing space formed by the sealing grooves 501 of the two is equipped with a sealing ring (not shown in the figure), which can ensure the sealing of the tank 100. This is a key prerequisite for the siphon principle to take effect, and avoids insufficient pressure difference between the inside and outside of the tank 100 and failure of water diversion due to air leakage.

[0021] Specifically, this device serves as a priming system for pumps. Its core logic is based on the siphon principle. Furthermore, the aperture of the grid plate 300 decreases sequentially from the inlet to the outlet. The side of the grid plate 300 facing the inlet is the filtration area. Specifically, before starting the device, the storage cavity 200 must be filled with water and the top cover 600 closed. This creates a sealed environment inside the tank 100. When the pump starts, the water flow at the outlet pipe 102 is drawn away, causing a rapid decrease in pressure inside the tank 100, forming a negative pressure ring lower than atmospheric pressure. In this environment, external water sources (such as municipal sewage) are "forced" into the storage cavity 200 from the inlet pipe 101 under atmospheric pressure, completing the water intake process and continuously supplying water. For the needs of "graded filtration and water quality analysis," the device achieves interception through the cooperation of the grating plate 300 and the filtration space 400. During normal water intake, the limiting plate 302 of the grating plate 300 engages in the second limiting hole 702 of the top cover 600, placing it in the "filtration position." At this time, the mesh size of the four sets of grating plates 300 can be set to "gradually decrease" as needed, such as... Figure 5 As shown, after the water flows into the liquid storage cavity 200 from the inlet pipe 101, it first enters the first filtration space 400 (that is, the first filtration space 400 formed between the inlet pipe 101 and the first grid plate 300), and then flows through different filtration spaces 400 in sequence, and finally exits from the outlet pipe 102 through the fifth filtration space 400 (that is, the fifth filtration space 400 formed between the outlet pipe 102 and the fourth grid plate 300). When passing through the grid plate 300 with larger mesh, large-diameter impurities such as household waste fragments are intercepted; and when passing through the grid plate 300 with smaller mesh, small-diameter impurities such as sludge particles and fibers are intercepted.

[0022] It needs to be explained that the mesh size of the grille 300 is adjusted progressively in a gradient manner. After the water flows into the liquid storage cavity 200 from the inlet pipe 101, it flows through different filtration spaces 400 in sequence. The mesh size of the grille 300 in each space changes in a stepwise manner. The first grille 300 uses 1-6 mesh, and this device uses 2 mesh (single hole size is about 12.5mm). This mesh size can intercept large-sized impurities in municipal sewage, such as fragments of domestic waste (such as plastic scraps, food scraps), plant debris, etc., which will remain in the first connecting space. Subsequently, the uninterrupted water flows into the second filtration space 400, where the mesh size of the second grille 300 increases to 6-20 mesh, and this device uses 10 mesh (single hole size is about 2mm). This can intercept medium-sized sludge clumps, long and coarse fiber bundles, etc., and subsequent filtration spaces... The mesh size of the 400 mesh grid continues to increase from 300 mesh (e.g., 20-40 mesh, 40-60 mesh, 60-100 mesh, etc.), and the single hole size is further reduced to 0.5mm, 0.35mm, and 0.2mm. This can intercept small particles of silt, fine fibers, suspended colloids, and other small-diameter impurities, which will then be sequentially held in the third, fourth, and fifth filtration spaces 400. The volume ratio of filtration space 400 to tank 100 is 1:5, meaning that the volume of filtration space 400 is one-fifth of the total volume of tank 100. If the total volume of tank 100 is 500 liters, then the volume of filtration space 400 is 100 liters; if the total volume of tank 100 is 1 cubic meter, then the volume of filtration space 400 is 0.2 cubic meters, thus creating a separate filtration state between filtration space 400 and tank 100.

[0023] The different filtration spaces 400 will retain impurities of corresponding particle sizes. The shape and content of impurities in each space can be directly viewed by opening the top cover 600. For example, in municipal sewage scenarios, operators can judge the degree of domestic pollution in sewage by the proportion of domestic waste fragments in the first filtration space 400; and analyze the silt concentration in sewage by the silt particle content in the subsequent filtration spaces 400.

[0024] Specifically, after observing and recording the sludge particle content in the filtration space 400, when backflushing the filtration space 400 is required, the locking bolt 800 can be loosened to open the top cover 600. The grating plate 300 can be rotated 180° around the center of the tank body 100, and then the locking bolt 800 can be tightened to make the limiting plate 302 engage with the first limiting hole 701 of the top cover 600, thus limiting the grating plate 300 to prevent rotation. This allows switching to the "backflushing station". At this time, the orientation of the grating plate 300 forms an angle difference with the original filtration station, and the flow path of the water in the liquid storage cavity 200 changes relative to the original filtration direction. The high-speed water flow will impact the impurities attached to the surface of the grating plate 300, removing them from the grating. The impurities removed from the mesh of the grating plate 300 are discharged from the tank 100 through the outlet pipe 102. After cleaning, simply rotate the grating plate 300 back to the "filtration station" and re-lock the top cover 600, and the equipment can resume normal operation. The entire process does not require disassembling the grating plate 300. It can be done by using a robotic arm or rotating the grating plate 300. Since the grating plate 300 is made of metal, it will not be damaged during rotation. Alternatively, the grating plate 300 can be lifted out directly without rotating and backflushing it. A high-pressure water gun can then be used to backflush the mesh of the grating plate 300 from the outside, and the liquid storage cavity 200 inside the tank 100 can be cleaned. Both methods are acceptable.

[0025] In the above scheme, the filtration space 400 formed by the multi-component graded grid plate 300 can not only retain the core function of siphon water attraction, but also distinguish the content distribution and morphological characteristics of impurities of different particle sizes in each filtration space 400. The water quality fluctuation can be traced through the characteristics of impurities, providing a direct basis for water quality analysis.
