Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following specific examples.

Referring to fig. 1, a prefilter with a dosing and cleaning function comprises a filter head 7, a water inlet 3, a water outlet 8, a filter flask 4, a water filtering screen 10, a sewage outlet 5, a dosing port 6, a sealing cover 1, a dosing screen 9 and a sealing gasket 2.

The filter head 7 and the filter flask 4 are both hollow cylindrical cavities, wherein the filter head 7 is transversely arranged, the filter flask 4 is longitudinally arranged, and the filter head and the filter flask form a T shape. The left side and the right side and the upper side and the lower side of the filter head 7 are both provided with through holes communicated with the inner cavity of the filter head, wherein the left opening of the filter head 7 is connected with the water inlet 3, the right opening of the filter head 7 is connected with the water outlet 8, the upper opening of the filter head 7 is connected with the lower opening of the dosing port 6, and the lower opening of the filter head 7 is connected with the upper opening of the filter bottle 4. A valve is arranged at the water inlet 3. The upper end opening of the medicine adding opening 6 is covered with a sealing cover 1. In this embodiment, the medicine adding port 6 and the sealing cap 1 are connected by a screw manner. In order to improve the sealing performance, a sealing gasket 2 is arranged between the medicine adding opening 6 and the sealing cover 1. In this embodiment, the gasket 2 is a fluorine rubber gasket 2. The lower end opening of the filter flask 4 is connected with a sewage outlet 5, and the sewage outlet 5 is provided with a valve.

The water filtering screen 10 and the medicine adding screen 9 are both U-shaped. In this embodiment, the water filter screen 10 and the drug-adding screen 9 are stainless steel screens. The water filtering screen 10 is sleeved in the inner cavity of the filter flask 4, and divides the inner cavity of the filter flask 4 into an outer annular inner cavity and a central columnar inner cavity, the annular inner cavity is communicated with the water inlet 3 of the filter head 7 and the sewage outlet 5 of the filter flask 4, and the columnar inner cavity is communicated with the water outlet 8 of the filter head 7. In the longitudinal direction, the dosing filter screen 9 is located between the lower end opening of the dosing port 6 and the upper end opening of the filter flask 4. In the transverse direction, the dosing filter screen 9 is located in the middle of the filter head 7, i.e. between the water inlet 3 and the water outlet 8. The dosing filter screen 9 is positioned above the water filter screen 10, and the lower part of the dosing filter screen 9 is connected with the upper part of the filter screen. In this embodiment, the diameter of the dosing screen 9 is smaller than the diameter of the water filter screen 10, and the lower portion of the dosing screen 9 is located radially inside the upper portion of the water filter screen 10.

In the normal use process of the pre-filter, the valve at the water inlet 3 is opened, and the valve at the sewage outlet 5 is closed. Water flows from the inlet 3 of the filter head 7 into the pre-filter and flows into the annular interior of the filter flask 4 via the interior on the side of the inlet 3 of the filter head 7. Under the action of the water filter screen 10, large granular impurities in the water are left in the cylindrical inner cavity of the filter bottle 4, and the filtered water flows into the cylindrical inner cavity of the filter bottle 4 through the water filter screen 10 and flows out of the pre-filter from the water outlet 8 of the filter head 7 through the inner cavity on the side of the water outlet 8 of the filter head 7.

When the pre-filter or the water pipeline needs to be cleaned or disinfected: firstly, a valve at the sewage outlet 5 is opened, and the water in the pre-filter is taken to lead the impurities on the water filtering screen 10 to be discharged from the sewage outlet 5. Then, the valve at the water inlet 3 is closed, the sealing cover 1 of the chemical feeding port 6 is opened, and the valve at the sewage draining port 5 is closed after the water in the front filter is drained. Then, a proper amount of liquid or solid cleaning agent or disinfectant is added from the medicine adding opening 6 according to the application, and when the cleaning agent or disinfectant is solid, the medicine adding filter screen 9 can prevent the solid cleaning agent or disinfectant from being dissolved and incompletely flowing into the pipeline to cause blockage. After the medicine is added, the sealing cover 1 is covered, the valve at the water inlet 3 is opened, the pre-filter enters the normal use process, and in the process, the disinfectant or the cleaning agent enters the pre-filter and the water pipeline along with the pre-filter to clean or disinfect the pre-filter.

It should be noted that, although the above-mentioned embodiments of the present invention are illustrative, the present invention is not limited thereto, and therefore, the present invention is not limited to the above-mentioned embodiments. Other embodiments, which can be made by those skilled in the art in light of the teachings of the present invention, are considered to be within the scope of the present invention without departing from the principles thereof.
