Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, specifically relating to an improved raw water sampling tank. Background Technology

[0002] With the continuous strengthening of environmental protection regulations and the constant improvement of water resource management precision, raw water sampling, as a core link in water quality monitoring, pollution source tracing, and process control, has become crucial in directly impacting the operational efficiency of the environmental governance system. In fields such as municipal water supply, sewage treatment, industrial recycling systems, and ecological monitoring, the rational design of sampling tanks is increasingly becoming a critical factor affecting monitoring quality.

[0003] There are two major technical challenges in current raw water sampling tanks that urgently need to be addressed: Firstly, due to limitations in traditional tank structure design, such as redundant internal flow channels and complex chamber partitions, biofilm and particulate matter can easily remain in dead corners during cleaning operations, forcing the suspension of online monitoring instruments during manual maintenance and creating a vacuum period for water quality monitoring data interruption; secondly, algae and biological attachments growing in raw water will continuously change the physicochemical properties of water samples, leading to periodic distortions in key sampling indicators such as turbidity and COD.

[0004] This structural contradiction not only threatens the integrity of the water quality monitoring system but also poses a risk of misleading process control decisions. Therefore, designing a new type of sampling tank that combines filtration efficiency with ease of maintenance has become an urgent need to overcome existing technological bottlenecks. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses an improved raw water sampling tank. A detachable stainless steel filter layer is added to construct a primary protection system, effectively preventing algae, microbial communities, and suspended impurities from entering the sampling circuit of the tank, thus ensuring the authenticity of water quality monitoring data. Simultaneously, a secondary water tank module is configured to enable continuous and stable operation of the online monitoring system during maintenance, completely resolving the monitoring gap caused by manual tank cleaning.

[0006] To achieve the above objectives, the specific technical solution of this application is as follows:

[0007] An improved raw water sampling tank includes a raw water sampling pump, an inlet pipe, a water tank, a main overflow pipe, and a raw water instrument. The water tank includes a main water tank and a secondary water tank. An inlet pipe regulating valve is provided on the inlet pipe, and a main overflow pipe regulating valve is provided on the main overflow pipe. A detachable filter structure is provided at the connection between the inlet pipe and the main water tank. The main water tank has a main overflow pipe. The main water tank and the secondary water tank are separated by a partition plate, the height of which is greater than the height of the main overflow pipe but less than the height of the water tank. The water tank has a tank cover plate, and an instrument detection port is provided on the tank cover plate. An electrode probe connected to the raw water instrument extends into the water tank from the instrument detection port.

[0008] Based on the above technical features, preferably, the filter structure is a stainless steel filter layer, which is connected to the connection between the water inlet pipe and the main water tank by filter clips.

[0009] Based on the above technical features, the filter clip is a quick-release structure, including a spring lock and a slot. The slot is fixed to the inner wall of the water inlet of the water tank, and the spring lock is connected to the edge of the stainless steel filter layer.

[0010] Based on the above technical features, preferably, the mesh size of the stainless steel filter layer is in the range of 50-200 mesh, and the specific mesh size can be adjusted according to the characteristics of suspended solids in the raw water. The surface of the stainless steel filter layer is provided with an anti-bioadhesion coating.

[0011] Based on the above technical features, preferably, the volume of the auxiliary water tank is 30%-50% of that of the main water tank, and the auxiliary water tank is equipped with a spare overflow channel for redundant protection under extreme operating conditions.

[0012] Based on the above technical features, preferably, both the water tank and the water tank cover are made of stainless steel.

[0013] Based on the above technical features, preferably, the partition plate includes a stainless steel plate body, and rubber strips are provided at the front, back and bottom of the plate body.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application constructs a primary protection system by adding a detachable stainless steel filter layer with customizable mesh size, which effectively blocks algae, microbial communities and suspended impurities in the water from entering the sampling circuit of the water tank, ensuring the authenticity of water quality monitoring data. It is especially suitable for water quality monitoring scenarios in high algae water sources, and provides a more targeted sampling solution for water quality assessment.

[0016] The auxiliary water tank module is configured to ensure the continuous and stable operation of the online monitoring system during maintenance operations, completely solving the monitoring gap problem caused by manual cleaning of the water tank;

[0017] When performing cleaning operations, the system switches to the auxiliary water tank working mode, fills the auxiliary water tank, and closes the main water tank inlet pipe and the main overflow pipe regulating valve. The electrode probe of the raw water instrument is then moved to the auxiliary water tank monitoring position. At this time, personnel can perform operations such as removing biofilm and replacing filters in the main water tank. This design breaks through the limitation of traditional maintenance requiring shutdown and interruption of sampling. By spatially transferring the monitoring points, it achieves full-dimensional maintenance of the main water tank while ensuring sampling continuity, significantly improving equipment operation and maintenance efficiency and overall system stability, forming a comprehensive water quality sampling solution that combines innovation, practicality, and ease of maintenance.

Preferably, the partition plate 9 includes a stainless steel plate body 901, and rubber strips 902 are provided at the front, back, and bottom of the plate body to ensure a sealed connection with the water tank. The main water tank 5 is provided with a main overflow pipe 7; the height of the partition plate 9 is greater than the height of the main overflow pipe 7 but less than the height of the water tank 4.

[0026] The inlet pipe 2 is equipped with an inlet pipe regulating valve 3, which is used to control the opening and speed of water inlet. The main overflow pipe 7 is equipped with a main overflow pipe regulating valve 11, which is used to control the opening and speed of overflow.

[0027] like Figure 1 and Figure 2 A detachable filter structure is provided at the connection between the water inlet pipe 3 and the main water tank 4. The filter structure is a stainless steel filter layer 15, which is connected to the water inlet 501 by a filter clip 16. The filter clip is a quick-release structure, including a spring lock 16 and a slot 502. The slot is fixed to the inner wall of the water inlet 501 of the water tank, and the spring lock 16 is connected to the edge of the stainless steel filter layer 15.

[0028] Preferably, the stainless steel filter layer 15 has a mesh size range of 50-200 mesh, and the specific mesh size can be adjusted according to the characteristics of suspended solids in the raw water.

[0031] Working principle:

[0032] Raw water is filtered through a customized stainless steel filter with adjustable parameters based on the characteristics of suspended solids in the raw water. After primary purification, the water is injected into the main water tank. When the water level in the main water tank reaches a preset threshold, the main overflow pipe is opened to achieve constant water level control. Under extreme water intake conditions, the backup overflow channel of the auxiliary water tank is activated simultaneously, forming a dual water level protection mechanism.

[0033] During cleaning operations, the system switches to auxiliary water tank mode, fills the auxiliary water tank, and closes the main water tank inlet channel and overflow regulating valve. The electrode probe of the raw water instrument is then transferred to the auxiliary water tank for monitoring. At this time, personnel can perform operations such as biofilm removal and filter replacement in the main water tank. This design overcomes the limitations of traditional maintenance that requires system shutdown and sampling interruption. By spatially shifting the monitoring points, it achieves full-dimensional maintenance of the main water tank while ensuring continuous sampling, significantly improving equipment operation and maintenance efficiency and overall system stability.
