Description

FILTER for 1/1 water

The proposed utility model relates to devices for clean water filtering and is intended to produce environmentally friendly water in (public, catering, hotels, medical institutions, etc.

A filter for filtration in an upward flow is known, which includes a water distributor in a separate housing in which there is a layer of film pywuiero material (see Japanese application N 2-39922, class V01D24 / 02, 1991). Also known is a household filter for water purification, consisting of a housing and coaxial porosities installed in it -; cylinders, between which a bulk sorbent is located (see A.S.SSSR W 1690313, class B01D24 / Ov, 1991). These filters have a rather complicated design. In addition, a large amount of metal is required for IR manufacturing.

The closest to the proposed utility model by its theological essence is the Sorption filter according to the USSR author's certificate N 1567243, cl. E 01D24 / OO, 199O, (prototype). The specified sorption filter consists of a cylindrical body, inside of which there is a perforated tube plugged from below and a bulk load of granular sorbent. Bulk loading is held by a cylindrical grate with microporous carbon cloth fixed on it, which is the second filtering element. Purified water is supplied from above into the central pipe, squeezed out of it through perforation, passes first through bulk sorbent, then through coal fabric and flows to the bottom of the body

The disadvantage of this prototype is its complexity, due to the presence of two filter elements. In addition, filters of this design are unfortunate for maintenance, since when washing them, the sediment accumulated mainly in the upper layer of the sorbent is washed off by the washing liquid down and contaminates the lower, relatively clean layers of the sorbent. For this reason, washing such a filter requires a lot of time and a significant flow of washing liquid

The technical task (goal) of the utility model is to simplify the design, increase the ease of maintenance.

The technical solution to this problem is achieved by the fact that in the filter for water purification, which includes a housing having a throat with a lid and a bottom containing a central pipe connected to an inlet nozzle for supplying water installed on the lid, a filtering charge, and an outlet nozzle for draining purified water , the separation grid between the loading and the outlet pipe, the central tube has an expansion funnel at the end, the outlet pipe is mounted on the cover, while the separation grid is mounted on the neck of the housing, the filter is different Xia also characterized in that the expansion cone is provided with a mesh 53ODY splitter, being provided between the divider and the bottom of a gap.

The technical result achieved is to simplify the design (the proposed filter has only one cover and one filter element) while increasing efficiency (with filter 1 1 and in the upstream flow, water is more evenly distributed over the cross section of the filter load). In addition, the washing process of the filter is simplified, since in the direction of filtration from bottom to top, the lowest layer of the filter load is the most contaminated, which is relatively easy to rinse by supplying the washing liquid through the inlet with an open drain (improving convenience).

B01 D24 / 16

In the example of a specific HcnojiHeHvia, the filter for water purification consists of a cylindrical housing 1 with a neck 2 and a stand 3-. Inside the case there is a usHTpajibHasi pipe 4, which is connected to the inlet pipe 5 for supplying purified water. On the neck 2, the cap 6 is closed. On the lower end of the pipe 4 there is an expansion funnel 7, which is connected with a mesh divider S.

In the case there is a bulk filter load 9 conventionally shown several granules). For a specific example, for the Rosa-Super 100 Sem Passport water purification filter, passport, Appendix 7), the filter load is made in the form of a complex litter (s “2kta, which includes activated charcoal of brand rye, selective fezhel sorbent and bactericidal silver-containing material. When using a filter housing for preliminary water purification from mechanical impurities, the filter load contains gravel, sand, etc.

The neck 2 is covered by a dividing grid 10. On the lid & there is installed an outlet pipe 1.1 for drainage of purified water. A drain pipe 12 is attached to the bottom of the housing 1, which is connected with a hole 13.

For a case of significant contamination of water with mechanical impurities in the design of the Rosa Super filter, it is possible to supply water through a standard pre-filter Sem Appendix 7, p. 5) f which is connected to the inlet 4 using a tubular square 14. The arrows in the drawing conventionally show the direction of movement water.

The filter for water purification works as follows. The inlet pipe 5 is connected to the water supply source directly or through a prefilter, and the outlet pipe // is connected to the consumer eyes /. water. The purified water enters through the inlet pipe 5 to the mains of the 4th pipe 4 and through the funnel 7 is evenly distributed at the bottom of the casing over the entire cross section of the filter and load. Upon further admission, water moves from bottom to top through the load layer 9, while being purified from harmful impurities. Having reached the neck 2, the purified water passes through the grid Yu and through the outlet pipe 11 enters the consumer. In this case, the mesh 10 prevents washing out of the load from the housing 1.

To clean the filter of sediment, turn off the plug 13 and attach the drain pipe 12 to the sewer. Then, the inlet pipe 5 is connected to a source of washing liquid. The washing liquid, passing through the load, washes off the sediment from its lower, most contaminated layer, through the drain pipe directly to the sewer. This prevents the transfer of sediment through the entire thickness of the load. This design feature of the proposed filter significantly reduces the time of washing and reduces the flow rate of the washing liquid.

According to the scheme described above, a gamma filter of various capacities was manufactured at Compomet Kentech JSC in Yekaterinburg, and their tests were performed, which showed good results.

The proposed filter for water purification meets the criteria of novelty and industrial applicability, and therefore appears to patent protection certificate for a utility model.
