Description

Two parallel six-inch enlarged combined mesh filter

technical field

The utility model belongs to industrial and agricultural water-saving filtering devices, in particular to a two-parallel six-inch enlarged combined net filter. the

Background technique

At present, the industrial water treatment and water-saving irrigation that are being gradually promoted, such as water treatment and drip irrigation in waterworks, have relatively high water quality requirements for domestic water and irrigation water. Impurities and sediment in the water must be filtered out through filters in advance to prevent drip irrigation. With blockage and meet domestic water standards. The traditionally used filter is a sand filter or a manual cleaning screen filter. Under the same flow conditions, the gravel filter has a large volume, large head loss, and the power of the corresponding power equipment is large, which is uneconomical; the gravel filter used alone or in parallel must be equipped with a special cleaning pump. Stopping work or stopping one of the parallel connections will affect the normal operation of the system and reduce work efficiency. When the manual cleaning net filter used in single or parallel connection needs to be cleaned during the working process, the filter must stop working or stop one of the parallel connection, pull out the net and perform manual cleaning, which will affect the normal operation of the system and reduce the work efficiency. There is a large-diameter filter net in the filter barrel of the manual cleaning screen filter used in single or parallel connection, the filter area is small, and the flow rate is obviously small. the

Contents of the invention

The purpose of this utility model is to provide a two-parallel six-inch enlarged combined mesh filter, which can realize manual hydraulic cleaning of the filter mesh, without pulling out the mesh and cleaning it with clean water and a brush, with high efficiency and energy saving due to small water head loss , low management cost and labor intensity, one large-diameter filter screen in the uniform specification filter bucket is increased to six small-diameter filter screens, thereby increasing its filtration area. the

The purpose of this utility model is to provide a two-parallel six-inch enlarged combined mesh filter, including two filter buckets with exhaust valves on the top and side and bottom water inlet and outlet pipes with water inlets and outlets. Its characteristics are: the side, bottom inlet and outlet of the filter barrel are each connected in parallel with a horizontal inlet and outlet pipe through the soft connection of the butterfly valve, and a sewage valve is set under the water inlet of each filter barrel, and six drain valves are installed in each filter barrel. A 304L stainless steel, cylindrical filter with upper plug and lower opening. In addition, install a pressure gauge at the water inlet of the water inlet pipe and the water outlet of the water outlet pipe. the

The working principle of the utility model is: when the water containing impurities enters the filter chamber of the filter barrel from the water inlet, and the water containing impurities enters from the outer wall of the filter screen and flows out from the inner wall of the filter screen, the impurities are attached to the outer wall of the filter screen. Clean water flows out from the inner wall of the filter screen, passes through its lower opening, and flows into the water outlet pipe through the water outlet of the filter barrel for utilization. When there is a lot of dirt attached to the outer wall, the pressure gauge at the inlet and outlet of the filter will show a certain pressure difference. When the pressure difference reaches the expected value, the sewage discharge work must be carried out; Sewage valve, at this time, part of the clean water filtered by other filters flows back into the filter to be discharged, and flows out from the inner wall of the net to the outer wall of the net, forcing the dirt adsorbed on the outer wall of the net to leave, and is discharged from the bucket from the sewage outlet , carry out backwashing, after seeing clear water, close its drain valve and open the water inlet valve to make it enter the normal working state; then carry out backwashing work on the next filter barrel, the method is the same as above. The utility model has a good effect of manual hydraulic backwashing, does not need a hand brush to clean the filtering net, has a large filtering area, small water head loss, good energy saving effect, convenient and quick cleaning, low management cost and labor intensity, and embodies the superiority of water-saving irrigation technology , so that water-saving irrigation appears as energy-saving irrigation, and accelerate its popularization rate in the local area. the
