Background Art

It is a common phenomenon that there is dirt in the water in the pipeline. If it is not cleaned in time, it is easy to cause the pipeline to be blocked due to the accumulation of dirt in the pipeline, affecting normal work. Nowadays, there are two main methods for filtering water in pipelines: Y-type filters and in-pipe filters. They all have the disadvantages of filter mesh deposition that cannot be discovered in time, resulting in increased pressure loss and decreased flow rate in the pipeline, and the need to stop water supply during sewage discharge.

Summary of the invention

The technical problem to be solved by the utility model is to overcome the existing defects and provide an online filtering and draining device. The online filtering and draining device is used to filter the water in the pipeline, which can prevent the pipeline from being blocked, and the online drainage improves efficiency and reduces costs.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an online filtering and sewage discharge device, including a filter screen arranged in a filter valve body, a water valve is arranged in a water inlet pipe connected to a water inlet of the filter valve body, a pre-filtration pressure gauge is arranged on the water inlet pipe port of the water inlet pipe, the water inlet pipe between the pre-filtration pressure gauge and the water valve is connected to the backwash pipe port of the filter valve body through a backwash pipe, a backwash valve is arranged in the backwash pipe, a filter port pressure gauge is arranged on the water outlet of the filter valve body, and a sewage discharge valve is arranged in the sewage discharge port of the filter valve body.

The utility model has the following technical benefits: the utility model can filter dirt in the water in the pipeline, prevent pipeline blockage and water pressure loss caused by dirt accumulation, and avoid poor water flow caused by pressure loss; the utility model has a simple structure, low cost, and is easy to operate. Online sewage discharge improves efficiency and reduces costs. The utility model can be used for online sewage discharge in water.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG1 is a schematic structural diagram of an online filtering and sewage discharge device of the present utility model.

DETAILED DESCRIPTION

The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG1 , an online filtering and sewage discharge device includes a filter valve body 1, a filter screen 2, a backwash valve 3, a water valve 4, a sewage discharge valve 5, a water inlet pipe 6, a backwash pipe 7, a filter port pressure gauge 8, and a pre-filtration pressure gauge 9.

One side of the filter valve body 1 is the water inlet 1-1, and the other side of the filter valve body 1 corresponding to the water outlet 1-2 is the water outlet 1-2. The upper end of the filter valve body 1 is the backwash pipe port 1-3, and the lower end of the filter valve body 1 is the sewage outlet 1-4.

The filter screen 2 is installed obliquely in the filter valve body 1, one end of the filter screen 2 is connected to the inner wall of one side of the filter valve body 1 near the lower end of the backwash pipe port 1-3, and the other end is connected to the inner wall of the other side of the filter valve body 1 at the lower end of the water outlet 1-2. The filter screen 2 is used to filter debris in the water, and the filter screen 2 is an elliptical filter screen.

The filter port pressure gauge 8 and the pre-filter pressure gauge 9 are respectively installed on the water outlet 1-2 pipe of the filter valve body 1 and the water inlet pipe port 6-1 pipe, and are used to detect whether the filter screen 2 is blocked due to dirt accumulation.

The water valve 4 is installed on the water inlet pipe 6 for online water supply;

The backwash valve 3 is installed on the water inlet pipe 6 before the water valve 4 and the backwash pipe 7 connected between the backwash pipe openings 1-3 for online sewage discharge;

The water inlet pipe opening 6-1, the water inlet 1-1 and the water outlet 1-2 are on the same axis diameter;

The sewage valve 5 is installed on the sewage outlet 1-4 of the filter valve body 1 for sewage discharge.

When the utility model is used for filtering normally, the water valve 4 is opened, the backwash valve 3 is closed, and the sewage valve 5 is closed. Water enters the filter valve body 1 through the water inlet pipe port 6-1, the water valve 4 and the water inlet 1-1 in sequence. The filter screen 2 blocks the debris in the water at the lower end of the filter screen 2, and the filtered water flows out through the water outlet 1-2 at the upper end of the filter screen 2, thereby filtering the water in the pipeline.

When the pressure value of the pressure gauge 8 at the water outlet 1-2 is less than the pressure value of the pressure gauge 9 before filtration at the water inlet pipe port 6-1, it means that the dirt filtered at the lower end of the filter screen 2 needs to be discharged; when the dirt is discharged, the backwash valve 3 is opened, the water valve 4 is closed, and the dirt attached to the lower end of the filter screen 2 moves to the sewage outlet 1-4. After the sewage valve 5 is opened, a pressure difference is generated between the upper end and the lower end of the filter screen 2, and the water flows from the upper end of the filter screen 2 to the lower end of the filter screen 2, taking away the dirt attached to the lower end of the filter screen 2 and discharging it through the sewage outlet 1-4, realizing the online sewage discharge process; after the sewage discharge is completed, the sewage valve 5 is closed, the water valve 4 is opened, the backwash valve 3 is closed, and the pipeline water filtration process is returned.

The utility model can filter dirt in the water in the pipeline, prevent pipeline blockage and water pressure loss caused by dirt accumulation, reduce energy loss caused by poor water flow during the thermal cycle, and can promptly detect and deal with dirt accumulation on the filter net without stopping water during the treatment process.

The above describes the basic principle, main features and advantages of the utility model. For those skilled in the art, the utility model is not limited to the details of the above exemplary embodiments, and can be embodied in other specific forms without departing from the basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the utility model.
