Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Figures 1-3 are an embodiment of the present utility model: a sewage filtration and separation device for water quality monitoring, including a separator housing 1 and a separator upper cover 2 constituting the main component of the sewage filtration and separation equipment, and the separator housing 1 The upper end of the inner wall is provided with an annular installation groove 3, and a filter screen 4 is detachably installed in the installation groove 3, and a separator silica gel pad for sealing is provided at the joint between the separator housing 1 and the separator upper cover 2 6. The separator shell 1 and the upper cover 2 of the separator are detachably connected by the quick-installation clamp 5, which is convenient for operation and maintenance. Separator shell 1, separator upper cover 2, separator silica gel pad 6, and filter screen 4 can be fixed with quick-installation clamp 5 and manually tightened, so the device has a simple structure, easy installation and disassembly, easy operation and maintenance, and the filter screen can be Different specifications can be replaced at any time, which is convenient for water sample collection and monitoring in various sewage environments.

The upper end of one side of the separator housing 1 is provided with a water inlet 7, and the water inlet end of the water inlet 7 is located below the filter screen 4, and the top of the separator upper cover 2 is provided with a water outlet 8, and one end of the water outlet 8 is installed with a fast The bottom of the separator housing 1 is provided with a sewage outlet 9, and a butterfly valve 10 is installed on the bottom of the sewage outlet 9. According to the demand for sampling and water distribution, the water sample enters the separator housing 1 through the water inlet 7, and the water After being filtered by the filter screen 4, the sample flows upward through the water outlet 8 at the upper end of the separator upper cover 2 and flows into the next module. The upper cover 2 of the separator is jointly compressed by the quick-installation clamp 5 to realize detachable installation.

After the sewage enters the separator housing 1, impurities precipitate in the separator housing 1, and at the same time the filtered impurities also precipitate to the sewage outlet 9 at the funnel-shaped position at the bottom of the separator housing 1, and a butterfly valve 10 is connected to a The quick connector is discharged to the outside.

The bottom of the inner cavity of the separator housing 1 is set in a conical structure, the water flow rate of the water inlet 7 is greater than the sewage flow rate of the sewage outlet 9, and the water flow rate of the water inlet 7 is greater than the sewage flow rate of the sewage outlet 9 and the water flow rate of the water outlet 8 Sum.

In order to realize the overflow formation at the water outlet 8 at the upper end of the upper cover 2 of the separator, according to the flow formula Q=VS, it can be known that the condition of S inlet>S row and S inlet<S row+S outlet must be satisfied at this time, and then the stability can be satisfied. The water sample filtered by the filter 4 can overflow upwards and flow into the next module through the water outlet 8 to complete the sampling and monitoring of the water sample. The size of the water inlet and outlet and the sewage outlet are parameterized to maintain the sampling process. Stability of medium water pressure.

According to the above conditions, the water sample enters the cavity of the separator upper cover 2 upward through the filter screen 4 in the separator housing 1, and the filtered water sample continues to overflow upward in the cavity of the separator upper cover 1, and finally overflows the entire After the separator cavity, it flows to the monitoring equipment through the drain port 8 at the top of the separator upper cover 2 to complete water quality sampling and monitoring.

In this device, in order to realize the overflow of water samples, the relationship between flow, flow velocity and cross-sectional area needs to be clarified, as follows:

If it can be seen from the flow Q=VS (V is the flow velocity, S is the cross-sectional area of the pipeline), the flow is proportional to the pipe diameter and flow velocity. The flow velocity is affected by the pressure, and when the pressure is high, the flow velocity increases and the flow rate also increases. Now only consider that the pressure can be fully converted into momentum, and the inflow flow Q ₁ can be deduced,

P=ρgH=ρg(Ho-sQ ² )

H＝Ho-sQ ²

In the above formula, H represents the pressure head (water inlet) at the outlet of the pump, in m; R is the pipe radius, in m; Ho represents the head of the pump when the flow rate is equal to 0, in m; s represents the internal friction of the pump; Q Indicates the water pump flow rate, unit m ³ /s; P indicates water pump pressure, unit Pa; ρ indicates water density, unit kg/m ³ ; g indicates gravity acceleration.

Therefore, the flow q expression of the bottom sewage outlet 9 is:

P = ρgh

In the above formula, h represents the liquid level height of the drain outlet when the overflow is stable, in m; r represents the radius of the sewage outlet, in m.

Therefore, the top outlet 8 overflow can only be realized when the overflow flow Q ₂ is Q ₁ -q and the inflow flow Q ₁ >q. When the water sample enters the separator shell 1 cavity, due to the inflow Q ₁ >q, so the liquid surface of the water sample moves upwards in the cavity, and after being filtered by the filter 4, it reaches the water outlet 8 at the top of the upper cover 2 of the separator, and then overflows to the monitoring equipment.

In addition, a butterfly valve 4 is installed at the sewage outlet 9 in this embodiment. Through the cooperation of the sewage outlet and the butterfly valve, the device can adjust the stability of the pressure and flow of the entire module, and the filtered impurities can be discharged from the sewage outlet in time to maintain the water sample parameters. Stable, the size of the cross-sectional area of the sewage outlet 9 can be adjusted through the butterfly valve 4, so that the water sample can reach the monitoring equipment under a slight pressure, so as to maintain the stability of the water flow and make the monitoring data more accurate.
