Description

A combined multifunctional centrifugal filter for agricultural irrigation

technical field

The utility model relates to a combined multifunctional centrifugal filter for agricultural irrigation, which is mainly used for filtering system water in an agricultural irrigation micro-irrigation system to ensure the long-term safe operation of the micro-irrigation system; it can also be applied in some industrial fields .

Background technique

At present, in the agricultural micro-irrigation system, the traditional ordinary centrifugal filter is mainly used to filter the system water. This filter uses the cyclone separation technology, which has a good separation effect compared with the impurities with high water density, such as sand and iron oxide scale. It does not work on impurities whose density is close to that of water or lighter than water, such as algae, weeds and other floating objects. Such impurities enter the irrigation system with the effluent of the filter. However, the water for agricultural micro-irrigation is generally taken from river water, and it is inevitable that the river water contains various impurities. In micro-irrigation, the terminal nozzle is small, and impurities can easily block the system. In order to prevent the occurrence of system blockage failure, a butterfly or a mesh filter is generally added to the outlet of the ordinary centrifugal filter, which makes the whole system more complicated, increases the floor space, and increases the capital investment of the system. .

Contents of the invention

The problem to be solved by the utility model is to provide a combined multifunctional centrifugal filter, which can not only filter heavy impurities such as sand and stones like ordinary filters, but also intercept light impurities such as algae and weeds to pass through, thereby Fully guarantee the water quality of the effluent, so that the effluent can be directly connected to the micro-irrigation system, without the need for subsequent butterfly or mesh filters. The utility model achieves one machine with multiple functions, which not only simplifies the filtering system, but also makes installation and maintenance more convenient, and also reduces capital investment.

The utility model is a combined multifunctional centrifugal filter for agricultural irrigation, which comprises a water inlet pipe, a water outlet pipe, a cover plate, a swirl fluid, a wedge-shaped filter net, and a sand storage tank. The cylinder body of the swirling fluid is tangent, the outlet pipe extends from the cover plate into the casing of the swirling fluid, the wedge-shaped filter screen is fixedly connected to the lower end of the outlet pipe, and the funnel mouth of the swirling fluid is connected to the sand storage tank.

As an improvement of the present invention, the wedge-shaped filter screen is connected to the flange at the lower part of the outlet pipe through bolts. In this way, when the wedge-shaped filter screen is blocked or needs to be replaced, the bolt can be loosened, and it can be taken out from the swirl body for cleaning or replacement. Among them, the filtering precision of the wedge-shaped filter net can be selected according to specific needs.

As another improvement of the present invention, the cover plate and the cylinder of the swirling body are connected by bolts. In this way, when the bolts are loosened, all parts inside the water outlet pipe and the swirl body can be cleaned and replaced, thus making installation and maintenance more convenient.

When the centrifugal filter of the present invention is working, water enters the water inlet pipe, and impurities with a higher density than water can directly enter the sand storage tank through the action of centrifugal force. Wait for the floating objects to be blocked outside the wedge-shaped filter screen, so that the water discharged from the outlet pipe can be directly connected to the micro-irrigation system, without additional follow-up discs or mesh filters, so that one machine can be used for multiple purposes and the filtration system can be simplified , It is more convenient to install and maintain, and also reduces capital investment.

detailed description

As can be seen from the accompanying drawings, the utility model is a combined multifunctional centrifugal filter for agricultural irrigation, which is characterized in that it includes a water inlet pipe 1, an outlet pipe 2, a cover plate 3, a swirling fluid 4, a wedge-shaped filter screen 5, a sand storage Tank 6, the water inlet pipe 1 is connected to the cylinder of the swirl body 4, and is tangent to the cylinder of the swirl body, the outlet pipe 2 extends from the cover plate 3 into the casing of the swirl body 4, and the wedge-shaped filter screen 5 is fixedly connected to the The lower end of the water outlet pipe 2 is connected to the sand storage tank 6 at the funnel mouth of the cyclone body 4 .

As an improvement of the present invention, the wedge-shaped filter screen 5 is connected to the flange 8 at the lower part of the water outlet pipe 2 through bolts 7 . Like this, when the wedge-shaped filter screen 5 is blocked or needs to be replaced, the bolt 7 can be loosened, and it can be taken out from the swirl body for cleaning or replacement. Wherein, the filtering accuracy of the wedge-shaped filter net 5 can be selected according to specific needs. Among them, the connecting flange is formed by plasma cutting, which is convenient for processing and low in cost.

As yet another improvement of the present invention, the cover plate 3 and the cylinder body of the swirling body 4 are connected by bolts 9 . In this way, when the bolt 9 is loosened, all parts inside the water outlet pipe 2 and the swirl body 4 can be cleaned and replaced, making installation and maintenance more convenient.

As another improvement of the present invention, the wedge-shaped filter screen 5 is made of SS304 or SS316 material, which is corrosion-resistant and has a long service life.

When the centrifugal filter of the present invention is working, water enters the water inlet pipe, and impurities with a higher density than water can directly enter the sand storage tank through the action of centrifugal force. Wait for the floating objects to be blocked outside the wedge-shaped filter screen, so that the water discharged from the outlet pipe can be directly connected to the micro-irrigation system, without additional follow-up discs or mesh filters, so that one machine can be used for multiple purposes and the filtration system can be simplified , It is more convenient to install and maintain, and also reduces capital investment.

The utility model can be realized by grafting a wedge-shaped filter net on the lower end of the water outlet of the filter on the basis of the common centrifugal filter. This new type can not only filter heavy impurities such as sand and gravel like ordinary filters, but also intercept light impurities such as seaweed and weeds to fully ensure the quality of effluent water. The effluent can be directly connected to the micro-irrigation system without additional follow-up The advanced butterfly or mesh filter achieves multiple functions in one machine, simplifies the filter system, makes installation and maintenance more convenient, and reduces capital investment.
