Detailed Description
The attached drawings are the best embodiments of the decontamination filter element, and the invention is further described in detail with reference to the attached drawings.
As shown in attached drawings 1, 2 and 3, the decontamination type filter element comprises a filter element 1, an end cover 2 and a dirt collection barrel 3. The filter element 1 adopts the prior art, and can be a cylindrical paper filter element, a chemical fiber filter element and a net type filter element.
The end cover 2 comprises an upper end cover 201 and a lower end cover 202, at least one of the upper end cover 201 and the lower end cover 202 is provided with a liquid outlet 203, and the liquid outlet 203 is communicated with the hollow part of the cylindrical filter element 1.
The inner side end faces of the upper end cover 201 and the lower end cover 202 are both provided with annular filter element positioning grooves 2a and dirt collecting barrel positioning grooves 2b in an inwards concave mode, and the dirt collecting barrel positioning grooves 2b are sleeved outside the filter element positioning grooves 2 a.
The filter element 1, the end cover 2 and the dirt collecting barrel 3 can be fixed into a whole in a mode that glue is poured into the filter element positioning groove 2a and the dirt collecting barrel positioning groove 2b, so that two ends of the filter element 1 and two ends of the dirt collecting barrel 3 are respectively glued and fixed with the upper end cover 201 and the lower end cover 202; or the two ends of the filter element 1 are clamped to the two filter element positioning grooves 2a, and rubber rings are sleeved outside the two ends of the filter element 1 to seal the filter element. The two ends of the dirt collecting barrel (3) are clamped inside the dirt collecting barrel positioning groove 2b, and rubber rings are sleeved on the outer sides of the two ends of the dirt collecting barrel (3) to seal the dirt collecting barrel; or the upper end cover 201 and the lower end cover 202 are fixedly connected through the fastening bolt 5, and the filter element 1 and the sewage collecting barrel 3 are clamped between the upper end cover 201 and the lower end cover 202, so that the filter element 1, the end cover 2 and the sewage collecting barrel 3 are fixed into a whole.
The dirt collecting barrel 3 is sleeved outside the filter element 1, and a clearance between the dirt collecting barrel 3 and the filter element 1 is a dirt collecting cavity 4.
The dirt collecting barrel 3 is provided with a plurality of liquid inlets 301, and a gap is reserved between the liquid inlets 301 and the lower end cover 202. In order to increase the space for impurities that can be accommodated inside the dirt collection chamber 4, the liquid inlet 301 is disposed in the upper half of the dirt collection tub 3. The closer the liquid inlet 301 is to the upper end cap 201, the larger the space for impurities that can be accommodated inside the dirt collecting chamber 4.
When the dirt removing type filter element is used, the dirt removing type filter element is vertically placed in the filter, liquid entering the filter enters the dirt collecting cavity 4 through the liquid inlet 301, then the liquid is filtered through the cylindrical filter element 1, the filtered liquid flows into the hollow part of the filter element 1, and the liquid is discharged out of the filter through the liquid outlet 203 for use. After the supply of liquid to the filter is stopped, some of the liquid inside the filter will flow back. At this time, the impurities attached to the outer wall of the filter element 1 move downwards under the action of gravity, settle at the bottom of the dirt collecting cavity 4 and cannot flow back to the outside of the filter along with the liquid.
If the desmear filter element is placed horizontally or obliquely inside the filter, the inlet 301 is arranged above the central height of the dirt collection vessel 3 in order to increase the effective area of the dirt collection chamber 4.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
