The utility model adopts the following technical scheme: the sand-proof filter of the utility model comprises an oil pipeline, a valve, a primary filter, a secondary filter and an oil outlet pipe which are arranged in sequence, one end of the oil delivery pipe is connected with the oil delivery port, the other end of the oil delivery pipe is connected with the valve, the valve is connected with the primary filter through a pipeline, the bottom end of the primary filter is arranged in a hemispherical shape with an upward opening, the hemispherical bottom end of the primary filter is provided with a sand discharge port, a filter screen is arranged in the primary filter, the filter screen is arranged behind the hemisphere of the primary filter and completely covers the cross section of the primary filter, the secondary filter is communicated with the rear end of the filter screen of the primary filter through a pipeline, a filter layer and a supercharger are arranged in the secondary filter, the filter layer is arranged below an oil inlet of the secondary filter, the supercharger is arranged on the filter layer, the oil outlet pipe is arranged at the bottom of the secondary filter, and exhaust ports are formed in the top ends of the primary filter and the secondary filter.
Furthermore, the filter layer is a quartz sand filter layer, and the filter effect of the quartz sand filter layer is good.
Further, the booster is a pressure pump, and the pressure pump is suitable for boosting the fluid.
Furthermore, a cover body is arranged on the sand discharge port, and the cover body can be opened for collection.
Preferably, the filter screen is a metal filter screen, and the metal filter screen is corrosion-resistant.
Furthermore, a collecting box is arranged below the sand discharge port, so that the sand discharge port is convenient to collect.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the sand control filter has the advantages of simple structure, reasonable design, low cost and simple and convenient operation, and adopts multi-stage filtration to improve the filtering effect; and the bottom of the hemisphere is adopted to collect sand and stone, so as to prevent blockage.
Drawings
Fig. 1 is the structural schematic diagram of the sand control filter of the utility model.
The device comprises an oil delivery pipe 1, an oil delivery pipe 2, a valve 3, a primary filter 4, a secondary filter 5, an oil outlet pipe 6, a sand discharge port 7, a filter screen 8, a filter layer 9, a supercharger 10, an exhaust port 11, a cover body 12 and a collecting box.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the sand control filter of the utility model comprises an oil delivery pipe 1, a valve 2, a primary filter 3, a secondary filter 4 and an oil outlet pipe 5 which are arranged in sequence, wherein one end of the oil delivery pipe 1 is connected with an oil delivery port, the other end is connected with the valve 2, the valve 2 is connected with the primary filter 3 through a pipeline, the bottom end of the primary filter 3 is arranged in a hemispherical shape with an upward opening, the hemispherical bottom end of the primary filter 3 is provided with a sand discharge port 6, a filter screen 7 is arranged in the primary filter 3, the filter screen 7 is arranged behind the hemispherical shape of the primary filter 3 and completely covers the cross section of the primary filter 3, the secondary filter 4 is arranged at the rear end of the filter screen 7 of the primary filter 3 through a pipeline, a filter layer 8 and a booster 9 are arranged in the secondary filter 4, the filter layer 8 is, the oil outlet pipe 5 is arranged at the bottom of the secondary filter 4, and the top ends of the primary filter 3 and the secondary filter 4 are provided with exhaust ports 10.
Wherein, the filter layer 8 is the quartz sand filter layer, booster compressor 9 is the force pump, be equipped with lid 11 on the sand discharge opening 6, filter screen 7 is metal filter, sand discharge opening 6 below is equipped with collecting box 12.
When the valve is used specifically, firstly, the valve 2 is opened, so that petroleum enters the valve 2 through the oil conveying pipe 1 and is communicated to the primary filter 3, the petroleum filters sand and stone in the primary filter 3 through the filter screen 7 and enters the secondary filter 4, and the filtered sand and stone are gathered at the bottom of the hemisphere and are collected into the collection box 12 through the sand discharge port 6; a booster 9 is arranged in the secondary filter 4 for boosting, so that the secondary filtration is realized through a filter layer 8, finally, the petroleum is collected through an oil outlet, and the exhaust port 10 can exhaust at any time in the whole process, so that the overhigh pressure in the secondary filter 4 is prevented.
