Description

Improved water filtering device

Technical Field

The utility model belongs to a water purifying device, in particular to a modified water filtering device.

Background

The rainwater, pond water and the like collected in cities are often used for the water of the existing sanitation vehicles such as watering lorries, road sweeping vehicles, atomizing vehicles and the like, and the water is required to be filtered by a vehicle-mounted sewage filtering system during the work of the sanitation vehicles. The water filter among the sewage filtration system includes the body of compriseing base and the cover body and establishes at body bottom confined tube-shape filter core, and the body is equipped with water inlet, delivery port, with the straining chamber of water inlet intercommunication, establish at the sand catch basin of straining chamber lower part, with sand catch basin intercommunication and establish the row's of valve sand mouth, the filter core is established in the straining chamber to fix on the base through the screw rod, the upper end and the delivery port intercommunication of filter core are connected through the tighrening ring between the base and the cover body. When the water filter works, sewage (inlet water) enters the filter chamber from the water inlet, is filtered by the filter element and becomes clean water, and is discharged from the water outlet, and after particulate matters such as silt and the like are blocked by the filter element, a part of smaller particulate matters are attached to the outer wall of the filter element, and the other part of thicker particulate matters fall into the sand collecting tank and can be periodically discharged through the sand discharge port. Different from a household water filtering device, the existing water filter has large volume and large flow, so that the filtering area of a filter element is much larger, and the filter element basically adopts a folding structure. During filtering, particles such as silt in the sewage are particularly easy to attach to the gap and the outer wall of the filter element. At present, the water quality filter on the sanitation truck in China has a simple structure and no self-cleaning function, a driver needs to spend a large amount of time and energy to remove and clean the filter element, otherwise the filter element is easily blocked and even deformed and damaged under the action of water pressure, and the normal work of the truck is influenced. Because the water quality filter is generally arranged at the bottom of a vehicle, the work of dismantling and cleaning the filter element is very inconvenient, the consumed time is long, the working efficiency of a driver is greatly reduced, and the running cost of the vehicle is greatly improved by frequently replacing the filter element. Therefore, sanitation vehicle manufacturers and drivers urgently need self-cleaning water quality filters.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a water filter equipment that quality of water that can self-cleaning improves.

Realize the utility model discloses the technical scheme that the purpose was adopted as follows:

the utility model provides a modified water filter equipment, include the body, establish bottom confined tube-shape filter core in the body, the body be equipped with water inlet, delivery port, with the straining chamber of water inlet intercommunication, establish at the sand-collecting tank of straining chamber lower part, with the sand discharge mouth of sand-collecting tank intercommunication, the filter core is established in the straining chamber, the upper end of filter core with the delivery port intercommunication, the inner wall of straining chamber is equipped with the helicla flute that forms the radial rivers of flow direction filter core outer wall with the water conservancy diversion of intaking from the water inlet.

The body includes the base, the cover body of being connected with the base, the cover body passes through the tighrening ring and is connected with the base, filter chamber and sand catch basin are established at the cover internally, water inlet, delivery port are established on the base, be equipped with on the base and connect the chamber intercommunication water inlet and filter chamber, the upper end of filter core through cyclic annular supporting component with delivery port watertight intercommunication on the base.

The supporting component is in threaded connection with the water outlet, and a sealing ring is arranged between the supporting component and the water outlet.

Be equipped with the sealing washer rethread between the cover body and the base the tighrening ring is connected, and the tighrening ring passes through the screw and is connected with the base.

The filter element is fastened on the base through a screw rod penetrating through the bottom.

Advantageous effects

1. The utility model discloses a under the prerequisite that does not increase external force, the characteristic of silt is washed immediately to application rivers, through setting up the helicla flute at the filter chamber inner wall, the guide is intake and is produced the whirl in the filter chamber and form the radial rivers that flow to the filter core outer wall with higher speed and wash the filter core, prevents particulate matter such as silt to adhere to at the filter core surface, realizes the effect of filter self-cleaning filter core in the course of the work.

2. Use the utility model discloses a sanitation car is spraying the operation in, and the filter also is at the self-cleaning filter core, need not the driver and goes to manual the demolising washing every day, only needs the interval time to open the blowoff valve, with particulate matter discharge can, this time that will save the driver improves sanitation car's work efficiency.

3. Because the utility model discloses have self-cleaning function, need not tear open repeatedly, adorn and wash to improve life by a wide margin, reduce use cost.
