Description

A pre-pump filter

technical field

The invention relates to the technical field of agricultural water-saving irrigation filtering equipment, in particular to a pre-pump filtering device.

Background technique

Water-saving irrigation is a new type of high-efficiency water-based irrigation technology. The water flow aperture of the emitter in the drip irrigation system is generally very small, which is easily blocked by dirt and impurities in the water source. At present, the post-pump filter is generally used for filtration. In recent years, due to the diversification of water quality, especially the plankton that breeds in the water body, there are more dirt in the water when the water flows through the water pump, which is easy to block the water pump and cause the water pump to be damaged.

Utility model content

The technical problem to be solved by the utility model is to provide a pre-pump filter device for the above-mentioned deficiencies in the prior art.

The technical solution adopted by the utility model to solve the technical problem is: a filter device in front of the pump, including a filter body and a bottom plate, the upper part of the filter body is provided with a filter cover, and the inside of the filter body is provided with a flushing device, a filter frame is provided around the filter body, and a filter is provided on the filter frame; a cylinder is provided on the upper part of the filter cover, and a high-pressure water inlet is provided on both sides of the cylinder; There are flushing pipes all around the flushing device, and the opposite sides of the flushing pipes are connected and connected through a connecting plate and share a water inlet; the water inlet communicates with the high-pressure water inlet through a hose; the cylinder passes through The guide rail arranged on the bottom plate is connected and reciprocated on it so as to drive the movement of the flushing device and the flushing of the filter screen by the flushing pipe.

Furthermore, the filter frame is connected to the bottom plate through reinforcing ribs.

Furthermore, strip-shaped holes are provided on the reinforcing ribs, and the reinforcing ribs pass through the strip-shaped holes and are connected to the filter body through hooks.

Furthermore, the filter screen has three layers, wherein the middle of the filter screen is a 60-mesh stainless steel filter screen; the other two layers are stainless steel plate punching screens.

Furthermore, several water spray holes are arranged on the flushing pipe.

Furthermore, each spray hole is provided with a nozzle.

Furthermore, a water outlet is provided on one surface of the filter frame.

Compared with the prior art, the beneficial effect of the utility model is that the filter device in front of the pump is installed at the water inlet of the water pump, placed in a pool, river, pond or reservoir, and when the inhaled water passes through the filter device in front of the pump, organic or Inorganic debris and solid granular dirt are intercepted on the filter screen, preventing the dirt that may cause the blockage of the water pump and other subsequent equipment. Impurities are isolated from the outside of the filter screen. When a large amount of impurities are attached to the outside of the filter screen, the cylinder drives the movement of the flushing device and the impact of the flushing pipe to complete the self-cleaning of the filter screen.

Detailed ways

Below in conjunction with specific embodiment the utility model is described in further detail. 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.

As shown in Figure 1, a pump filter device includes a filter body 1 and a bottom plate 6, the upper part of the filter body 1 is provided with a filter screen cover 2, the internal flushing device 12 of the filter body 1, the A filter frame 7 is arranged around the filter body 1, and a filter 9 is arranged on the filter frame 7; a cylinder 3 is arranged on the upper part of the filter cover 2, and a high-pressure filter is arranged on both sides of the cylinder 3. The water inlet 5; the surroundings of the flushing device 12 are provided with a flushing pipe 13, and the opposite sides of the flushing pipe 13 are communicated and connected by a connecting plate 14 and share a water inlet 15; the water inlet 15 is connected to the The high-pressure water inlet 5 communicates; the cylinder 3 is connected through the guide rail 4 arranged on the bottom plate 6 and reciprocates therein so as to drive the movement of the flushing device 12 and the flushing pipe 13 to the filter screen. rinse.

Furthermore, in order to increase the overall stability of the filter device, the filter frame 7 is connected to the bottom plate 6 through reinforcing ribs 10 .

Further, the reinforcing rib 10 is provided with a strip-shaped hole 11 , and the reinforcing rib 10 passes through the strip-shaped hole 11 and is connected to the filter body 1 through a hook 8 .

Further, the filter screen 9 has three layers, wherein the middle of the filter screen 9 is a 60-mesh stainless steel filter screen; the other two layers are stainless steel plate punching screens.

Furthermore, the flushing pipe 13 is provided with several water spray holes 17 .

Furthermore, each spray hole 17 is provided with a nozzle 18 .
