Abstract

The utility model relates to a sandstone filter for irrigation, which is a cavity tank, the upper part of which is a cylindrical separation chamber, and the lower part is an inverted conical collection chamber, which is connected to the water inlet in the tangential direction of the outer peripheral wall of the separation chamber. The upper port of the cavity is covered with a top cover, and a water outlet pipe is inserted in the center of the top cover. A filter diversion net is installed at the lower port of the outlet pipe. The utility model uses the centrifugal principle to separate the larger particles of sand and gravel, and uses the filter screen to isolate floating objects with a smaller density such as water plants that cannot be separated and some small particles of sand and gravel, which can effectively ensure the purity of the water flow and prevent the entry of sand and sand drip tape.

Description

sand filter for irrigation

technical field

The utility model relates to a filter, in particular to a sandstone filter for irrigation.

Background technique

Agricultural drip irrigation is already a popular agricultural irrigation technology in my country, and the effect of drip irrigation is directly related to drip irrigation. In order to prevent floating objects with low density such as aquatic plants in the water and some sediments from clogging the drip irrigation belt, the separation of water flow and sediment should be carried out before the water flow enters the drip irrigation belt. The sand and gravel filters used today mostly use the centrifugal principle to separate the sand and gravel. However, due to the influence of the amount of water inflow, some floating objects with low density such as aquatic plants and some fine gravel in the water flow cannot be effectively separated, resulting in the drip irrigation belt. Blockage still occurs from time to time.

Contents of the invention

The purpose of the utility model is to propose a sandstone filter for irrigation which has a simple structure and can effectively separate the sandstone in the water flow.

The purpose of this utility model is achieved in this way: the sandstone filter for irrigation is a cavity tank, the upper part of which is a cylindrical separation chamber, and the lower part is an inverted conical collection chamber, which is connected to the tangential direction of the outer circumferential wall of the separation chamber. The water outlet is covered with a top cover on the upper port of the separation chamber, and a water outlet pipe is inserted at the center of the top cover. A filter diversion net is installed at the lower port of the water outlet pipe.

The utility model uses the centrifugal principle to separate the larger particles of sand and gravel, and uses the filter screen to isolate floating objects with a smaller density such as water plants that cannot be separated and some small particles of sand and gravel, which can effectively ensure the purity of the water flow and prevent the entry of sand and sand drip tape.

Description of drawings: the concrete structure of the present utility model is provided by following accompanying drawing and embodiment:

Figure 1 is a schematic diagram of the structure of a sand filter for irrigation.

Legend: 1. Inlet pipe, 2. Top cover, 3. Outlet pipe, 4. Separation chamber, 5. Filter diversion net, 6. Collection chamber.

Detailed ways:

The utility model is not limited by the following examples, and the specific implementation manner can be determined according to the technical scheme of the utility model and actual conditions.

Embodiment: As shown in Figure 1, the sand filter for irrigation is a cavity tank, the upper part of which is a cylindrical separation chamber 4, the lower part is an inverted conical collection chamber 6, and the top of the collection chamber 6 is provided with a sand discharge port. The tangential direction of the outer peripheral wall of the separation chamber 4 is connected to the water inlet pipe 1, and the upper port of the separation chamber 4 is covered with a top cover 2, and the center of the top cover 2 is inserted with a water outlet pipe 3, and the top of the water outlet pipe 3 stretches out from the top cover 2, and the bottom part It extends into the separation chamber 4, and the lower port is located in the separation chamber 4. A filter diversion net 5 is installed at the lower port of the water outlet pipe 3, and the mesh size of the filter diversion net 5 is 2-80mm, and the specific size is determined according to the filter medium.

After using the centrifugal principle to separate the larger particles of sand and gravel, use the filter diversion net 5 to isolate the floating objects with lower density such as aquatic plants and some small particles of sand and gravel that cannot be separated, and the separated sand and gravel are deposited in the collection chamber 6, Discharged from the sand outlet.

Claims (2)
