Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a dirty water filtering structure for a flaw detection tank includes a base 1, a filter tank 2, a tank cover 3, a filter element 4, a center rod 21, and a reinforcing member 5. The filter vat 2 is the cask column structure of upper end open-ended, and its axis is vertical, and filter vat 2 bottom is fixed with base 1 top. 3 bottoms of

bung

3 and 2 top threaded connection of filter vat, 3 tops of bung are the circular-arc structure of upwards protruding, thereby reduced debris and dropped to 3 tops of bung and take place accumulational probability, and be fixed with a plurality of strengthening ribs 31 on 3 tops of bung near 3 marginal positions of bung, the structural strength of bung 3 has been strengthened, reduced because of the too big probability that makes bung 3 produce and burst of atmospheric pressure in the filter vat 2, in addition, the staff can open bung 3 with the help of strengthening rib 31 easily, the probability of opening 3 in-process emergence skids of bung has been reduced.

The side wall of one side of the filter vat 2 is fixed and communicated with a sewage inlet pipe 22, a water pump 6 is arranged on the sewage inlet pipe 22, the side wall of the other side of the filter vat 2 is fixed and communicated with a purified water outlet pipe 23, the sewage inlet pipe 22 and the purified water outlet pipe 23 are both arranged at the position of the filter vat 2 close to the bottom of the filter vat 2, and the caliber of the purified water outlet pipe 23 is larger than that of the sewage inlet pipe 22, so that the filtered purified water can be discharged from the purified water outlet pipe 23.

The filter element 4 is arranged in the filter barrel 2 and used for filtering, and the water outlet end of the sewage inlet pipe 22 is positioned in the filter element 4. The central rod 21 is a vertically arranged round rod-shaped structure, the axis of the central rod coincides with the axis of the filter barrel 2, the lower end of the central rod 21 is fixed with the inner bottom wall of the filter barrel 2, the upper end of the central rod 21 penetrates through the barrel cover 3 and is in clearance fit with the barrel cover 3, the upper end of the central rod 21 is in threaded connection with a star-shaped operating handle 211, and the star-shaped operating handle 211 and the barrel cover 3 are kept sealed through an annular rubber sheet (not shown in the figure). Under the effect of water pump 6, in dirty water in the pond of detecting a flaw entered pipe 22 entering filter vat 2 from sewage, filter core 4 had played good filtering action to dirty water, and the water purification after the filtration is discharged from water purification exit tube 23, in the sewage water sump is got into again afterwards to this makes dirty water after the use obtain cyclic utilization, reduces the change frequency that the staff changed pond normal water, has practiced thrift the water resource.

In order to reduce the probability of damage to the threaded connection between the barrel cover 3 and the filter barrel 2 due to excessive other materials in the filter barrel 2, a pressure gauge 32 for detecting the air pressure inside the filter barrel 2 is arranged on the barrel cover 3, a pressure release pipe 33 is fixed on the barrel cover 3 and communicated with the barrel cover, and a pressure release valve 331 is connected to the pressure release pipe 33 in a threaded manner.
