Description

A pre-filter device

technical field

The utility model relates to the technical field of water filtration, in particular to a pre-filter device for water.

Background technique

With the continuous improvement of people's living standards and the aggravation of water pollution, people gradually have higher health requirements for water in daily life. At present, a pre-filter is usually used to purify the water once to filter out impurities and other pollutants in the daily water. The pre-filters on the market generally transport the water to be filtered to the filter part of the pre-filter, pass through the filter screen outside the filter part and then enter the filter part for internal filtration, and the filtered water flows out from the inside. Filtration can only simply intercept and filter out the larger impurities in the water through the filter screen, but cannot filter out the smaller impurities. At the same time, after the filter has been used for a certain period of time, the sediment will stick to the filter screen, which is troublesome to clean. If you want to clean it thoroughly, you need Disassemble or add a cleaning device separately. In addition, there are also some filters that use centrifugal filtration to centrifugally throw out impurities in water that are different in density from water to further improve the filtration effect. However, this kind of centrifugal filter needs to be driven by a motor, and the structure is relatively complicated. .

Utility model content

The purpose of the utility model is to provide a pre-filter device with simple structure, energy saving, good filtering effect and easy cleaning in order to solve the above-mentioned technical problems.

The technical solution adopted by the utility model for solving the above-mentioned technical problems is: a pre-filter device, including a bottle body, the top of the bottle body is provided with a water inlet for the water to be filtered to flow into the bottle body and for the filtered water to flow into the bottle body. The outlet for water to flow out; the inside of the bottle is provided with a filter screen that allows water to pass through and isolates impurities from the outside. The upper part of the filter screen is set with a rotating impeller. The water is led to the rotating impeller and then drives the diversion groove of the rotating impeller to rotate. The filter mesh is connected to the water outlet; the outside of the bottle is wrapped with a magnet that can absorb impurities in the water on the inner wall of the bottle; the bottom of the bottle is provided with a sewage outlet .

Further, the filter screen is configured as a cylinder.

Further, the sewage outlet is arranged below the filter screen.

Furthermore, the sewage outlet is also provided with a sewage valve capable of controlling the outflow of sewage.

The beneficial effects of the utility model are: the utility model is equipped with a rotary impeller capable of rotating under hydraulic impact, and the rotary impeller is used to drive the water body to rotate, and then the impurities are separated by centrifugal force, and at the same time, the magnetic force of the magnet is used to absorb impurities such as rust in the water into the bottle. The body and the filtering function of the filter screen filter the water, the filtering effect is good, the purification ability of the filtering device is improved, energy saving and environmental protection; when the utility model needs to be cleaned, it is only necessary to remove the magnet and open the drain valve, and the waste water will be drained by rotating the impeller. The water body rotates and scours the filter screen and the inner wall of the bottle to easily complete the cleaning of the filter device.

detailed description

As shown in the figure, a pre-filter device includes a bottle body 1, and the top of the bottle body 1 is provided with a water inlet 2 for allowing filtered water to flow into the bottle body 1 and a water outlet 3 for allowing filtered water to flow out. The inside of the bottle body 1 is provided with a cylindrical filter screen 4 that allows water to pass through and isolates impurities outside. Lead the water to be filtered to the rotating impeller 5 and then drive the diversion groove 6 of the rotating impeller 5 to rotate, and the filter screen 4 communicates with the water outlet 3 . The outside of the bottle body 1 is wrapped with a magnet 7 capable of absorbing impurities in the water on the inner wall of the bottle body 1 . The bottom of the bottle body 1 is provided with a sewage outlet 8, and the sewage outlet 8 is arranged below the filter screen 4, and the sewage outlet 8 is also provided with a sewage valve 9 that can control the outflow of sewage.

The water to be filtered enters from the water inlet 2 of the utility model, and under the action of the diversion groove 6, the water is guided to the rotating impeller 5 in the bottle body, and the rotating impeller 5 rotates under the impact of hydraulic force, and the water is driven by the rotating impeller 5 Also can rotate down, and then form centrifugal force, the impurity that density in water is greater than water will be thrown on the bottle body 1 inner wall of the present utility model under the effect of centrifugal force like this, is equipped with magnet 7 outside bottle body 1, is equipped with magnet 7 on magnet 7 Under the action of the magnetic force, the rust impurities are adsorbed on the inner wall of the bottle, and a filter screen 4 is arranged in the middle of the bottle body, and the filter screen 4 blocks the impurities and allows the filtered water to flow to the water outlet 3. The utility model is suitable for filtering granular impurities in water, improves purification ability under the action of magnetic force and centrifugal force, and has a certain magnetization effect on water. After the utility model has been used for a certain period of time, a certain amount of impurities will accumulate in the bottle body 1. When cleaning the device, you only need to take off the magnet 7 outside the bottle body, and the magnetic force of the magnet 7 will disappear, and open the bottom of the bottle body 1. The sewage valve 9, the impurities attached to the filter screen 4 and the rust-like impurities adsorbed to the bottle by magnetic force will be washed and discharged under the action of the rotating water flow. Because the water rotates in the bottle body during cleaning, it is convenient to wash away the impurities attached to the inner wall of the bottle and the filter net. After cleaning, close the blowdown valve again, install magnet 7 outside the device bottle body, and the utility model can resume work as required.

The above is only a preferred embodiment of the utility model, and for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made, and these should also be regarded as Protection scope of the present utility model.
