Abstract

The utility model relates to a novel sand carbon filter, which comprises a filter barrel, a filter, a water inlet pipe and a water outlet pipe, wherein the filter is arranged in the filter barrel, the water inlet pipe is arranged above the filter, the water outlet pipe is arranged under the filter, one end of the water inlet pipe is a water inlet, the other end of the water inlet pipe is provided with four water distribution heads, and the four water distribution heads are uniformly distributed above the filter so as to make water entering from the water inlet pipe uniformly distributed onto the filter after being sprayed out from the four water distribution heads, so the filtering effect of the filter is better.

Description

A kind of new molding sand carbon filter

Technical field

The utility model relates to the pure water process field, particularly a kind of new molding sand carbon filter.

Background technology

In the RO water treatment system in order to guarantee that counter-infiltration and nanofiltration system can stable operations, strictness to feedwater is just essential with processing, preliminary treatment is can produce the material that pollutes or cause deterioration to counter-infiltration and NF membrane in order to remove in the feedwater, in case pretreatment system can not play a role, there is pollutant to enter counter-infiltration and nanofiltration system, these materials may be at the film surface sediment, if contain microorganism in the feedwater, its breeding can cause more serious consequence, contain the more water source of particle suspensions, usually need the preliminary treatment of higher degree, just can reach the water inlet requirement of regulation, for microorganism and the high water source of content of organics, also need to use active carbon, the sand carbon filter is that this link is indispensable, existing sand carbon filter (as shown in Figure 1) has only a water inlet water distribution head 5, water inlet water distribution head 5 is located at the middle part of filter 2 tops, during water inlet, former water from water distribution head to around the ejection, under the effect of pressure, around the former water of water distribution head 5 ejections will spray to, most water is sprayed onto on the filter bucket wall and flows down through the bucket wall, then spray under the water distribution head less than water, cause the water distribution inequality under the spray, so just cause the filtration water yield at filter edges position more a lot of greatly than the middle part filtration water yield, the frequent big yield of filter edges filters the filter effect at this position is descended to some extent, and the middle part of filter can not be filled because the water yield is few and part plays a role in filtering, and causes the waste resource.

The utility model content

In order to solve above-mentioned shortcoming, the utility model provides a kind of new molding sand carbon filter, comprise filter vat, filter, water inlet pipe and outlet pipe, filter is located in the filter vat, water inlet pipe is located at the top of filter, outlet pipe is located at the below of filter, and an end of water inlet pipe is a water inlet, and the other end is provided with two water distribution heads at least.

One end of described water inlet pipe is a water inlet, and the other end is provided with four water distribution heads, and four water distribution heads are evenly distributed on the top of filter.

The utility model is provided with two water distribution heads at least, four water distribution heads that particularly evenly distribute, water is entered from water inlet pipe after respectively from the ejection of four water distribution heads, water can be distributed on the filter uniformly, make the filter effect of filter better.

Description of drawings

Fig. 1 is traditional sand carbon filter schematic diagram;

Fig. 2 is the utility model sand carbon filter schematic diagram;

Fig. 3 is another schematic diagram of the utility model sand carbon filter.

The specific embodiment

Below in conjunction with accompanying drawing, specify the utility model.

See also Fig. 2 and Fig. 3, a kind of new molding sand carbon filter, comprise filtration, 1, filter 2, water inlet pipe 3 and outlet pipe 4, filter 2 is located in the filter vat 1, and an end of water inlet pipe 3 is provided with water inlet 31, first water distribution head 321 is connected by water first water pipe 33 with second water distribution head 322, the 3rd water distribution head 323 is connected by second water pipe 34 with the 4th water distribution head 324, and second water pipe 34 is connected by the 3rd water pipe 35 with first water pipe 33, and the 3rd water pipe 35 is connected with the other end of water inlet pipe 3.

Former water is entered by the water inlet 31 of water inlet pipe 3, send into the 3rd water pipe 35, send into first water pipe 33 and second water pipe 34 respectively by the 3rd water pipe 35 again, first water pipe 33 and second water pipe 34 by first water distribution head 321, second water distribution head 322 and the 3rd water distribution head 323,324 ejections of the 4th water distribution head, are distributed on the filter 2 respectively uniformly again.

More than disclosed be specific embodiment of the utility model only, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the present utility model.

Claims
