Description

A centrifugal rainwater collection filter

technical field

The utility model relates to the technical field of rainwater recovery or secondary utilization, in particular to a centrifugal rainwater collection filter.

Background technique

The collection and utilization of rainwater can alleviate the two contradictions of water shortage and seasonal rainwater flooding, save water resources and reduce the pressure on the drainage system. In recent years, rainwater utilization has been widely used. At present, the structure of known filters is composed of a filter body, a filter screen and a sundry clearing outlet. When rainwater with debris passes through the filter, the filter screen can block the debris. When the known filter blocks the foreign matter in the water, the foreign matter remains in the filter, and it is necessary to open the foreign matter clearing outlet to remove the foreign matter.

In the actual use process, the operator needs to frequently clean up the sundries left in the filter screen. If the cleaning is not timely, it will affect the water flow capacity of the filter, and even blockage will stop the rainwater collection, which will bring great harm to the rainwater collection work. The biggest obstacle, a rainwater collection filter that can discharge debris freely and realize automatic rainwater filtration and automatic removal of impurities, has become an urgent problem in the field of rainwater recycling and secondary utilization.

Contents of the invention

The purpose of the utility model is to provide a centrifugal rainwater collection filter which can automatically remove sundries.

For realizing above-mentioned technical scheme, the technical scheme provided by the utility model is:

A centrifugal rainwater collection filter, comprising a cylindrical housing, the housing is composed of an upper housing and a lower housing fixed together, the upper part of the upper housing is provided with a rainwater inlet pipe tangentially, the The side of the lower housing is provided with a clean water outlet, and the housing is provided with a cylindrical filter screen, which is concentrically arranged with the housing, and the gap between the cylindrical filter screen and the housing forms a clean water outlet. In the water collection chamber, the lower part of the lower housing is provided with a sundry outlet.

Further, the center of the cylindrical filter screen is provided with a water diversion plate, the water diversion plate is conical, and the tip of the cone is fixed on the bottom of the lower casing and is located below the rainwater inlet pipe.

Further, the upper housing is provided with a filter upper interface below the rainwater inlet pipe, and the lower housing is provided with a filter lower interface, and the cylindrical filter is fixed through the upper filter interface and the lower filter interface. inside a cylindrical shell.

Further, an inspection port is provided on the upper part of the upper casing.

Further, a matching inspection port cover seat and an inspection port cover are respectively provided at the inspection port.

Further, the clean water outlet is arranged at the lowermost end of the side of the lower casing.

Further, the upper shell and the lower shell are fastened together by buckles.

Further, the clean water outlet is connected to a water storage tank.

In the above technical solution, the water inlet pipe and the upper casing are arranged tangentially. When the rainwater enters the casing, it advances along the tangential direction. Due to its own gravity and the action of the casing, it rotates down around the casing, and the impurities are filtered out through the filter. It is automatically discharged from the sundries discharge port, which will not affect the filtration of the filter net, and since the sundries will not directly remain in the filter net, it will not cause damage to the filter net, and the service life of the filter net is increased. The utility model has a simple structure. It is easy to use and maintain, and can quickly separate the leaves and other sundries in the rainwater, and remove the filter, so that the rainwater can be fully reused and water resources can be saved.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Fig. 1 is a structural schematic diagram of the present utility model, as shown in Fig. 1, a kind of centrifugal rainwater collecting filter comprises a cylindrical housing, and the housing is composed of an upper housing 3 and a lower housing 1 fixed together The upper part of the upper casing 3 is provided with a rainwater inlet pipe 7 tangentially, the side of the lower casing 1 is provided with a clean water outlet 12, and a cylindrical filter screen 2 is arranged in the casing. The filter screen 2 and the housing are arranged in concentric circles, and the gap between the cylindrical filter screen 2 and the housing forms a clean water collection chamber 10 , and the lower part of the lower housing 1 is provided with a sundry outlet 13 . The center of the cylindrical filter screen 2 is provided with a water diversion plate 4 , the water diversion plate is conical, and the tip of the cone is fixed on the bottom of the lower housing 1 , below the rainwater inlet pipe 7 .

The utility model is used for rainwater recovery and secondary utilization. The rainwater flows into the centrifugal rainwater collection filter from the rainwater inlet pipe. Since the rainwater inlet pipe and the shell are arranged tangentially, after the rainwater enters, it rotates downward along the inner wall of the shell. The clean water enters the clean water collection chamber through the filter holes of the filter screen. If the water intake is large, in order to prevent the clean water from flowing out directly from the sundries discharge pipe at the lower part of the shell, a conical water diversion plate is set in the middle of the filter screen to prevent the water flow When flowing down from the top, the water flow is diverted to the surroundings of the shell through the water separation plate. After the water flow passes through the water separation plate, there is a force from the center of the circle to the circumference, so that the water flows to the filter screen and enters the clean water collection chamber through the filter screen. The sundries and the like cannot pass through the filter screen and are discharged downwards from the sundries discharge port, and the water in the clean water collecting chamber is discharged from the clean water discharge port to flow to the reservoir.

The centrifugal rainwater collection filter provided by the utility model is convenient for production and use, and the housing can be set as two parts, the upper housing 3 and the lower housing 1, which are connected together by the housing buckle 9, and the upper housing A filter upper interface 8 is set to be fixedly connected to the upper end of the filter screen, and a filter screen lower interface 11 is arranged on the lower housing to be fixedly connected to the lower end of the filter screen, and the upper and lower ends of the filter screen are connected to the upper and lower shells The position where the body contacts is set to be sealed to prevent rainwater from directly entering the clean water collection chamber without the filter screen, or the water in the clean water collection chamber flows out from the position where the filter screen is in contact with the lower shell, that is, the water flows into the clean water through the filter screen The collection chamber is discharged from the clean water collection chamber through the clean water outlet.

In the centrifugal rainwater collection filter provided by the utility model, an inspection port is provided on the upper part of the upper casing, and a matching inspection port cover seat and an inspection port cover are respectively provided, and the inspection port cover is made of a transparent material or opened for inspection. The working condition of the centrifugal rainwater collection filter can be observed through the mouth cover, and the clean water outlet is arranged at the lowermost side of the lower casing to prevent clean water from flowing out from the clean water collection chamber along the filter screen.
