Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As described in the background, in the whole process of sewage treatment, effluent water of each treatment stage needs to be sampled periodically, and then detected by a water quality detector, such as a hash water quality analyzer, to determine the content of pollutants such as nitrate nitrogen, ammonia nitrogen, and the like in the sewage. However, the sewage often contains a large amount of impurities, such as suspended matters, macromolecular substances, etc., and the detection of pollutants such as nitrate nitrogen, ammonia nitrogen, etc., can be influenced by the presence of the impurities. Therefore, the water sample needs to be pretreated to remove impurities and then detected. Because the ceramic filter element 100 has the advantages of low price, good filtering effect and the like, the ceramic filter element 100 is widely adopted as a filtering material to filter sewage in sewage plants at present. However, the ceramic filter cartridge 100 is easily clogged after a certain period of use, and thus needs to be replaced periodically, which greatly increases the cost of the sewage plant.
In order to solve the problem, the present invention provides a backflushing type water sample filtering device, which comprises a hollow ceramic filter element 100 and a suction pump 400. Referring to fig. 1, a plug cap 200 is disposed on the top of the ceramic filter element 100, a connector 210 communicated with the inner cavity of the ceramic filter element 100 is integrally formed on the upper surface of the plug cap 200, the connector 210 is connected to the water inlet of the suction pump 400 through a sampling tube 300, so that the ceramic filter element 100 is placed in a water body to be detected, the suction pump 400 is started, a water sample is filtered by the ceramic filter element 100 and then discharged from the water outlet of the suction pump 400, and then the content of nitrate nitrogen and ammonia nitrogen or other pollutant indexes in the water sample can be detected through a hash water quality analyzer or other detectors. Preferably, the surface of the connector 210 is provided with threads so as to be threadedly coupled with the sampling tube 300 for easy installation. In this embodiment, the lower end of the cap 200 has a cock 220 portion made of rubber, and the cock 220 portion is inserted into the inner cavity of the ceramic filter element 100. The plug 220 has elasticity, so that the plug cover 200 can be conveniently inserted on the ceramic filter element 100, and the tightness of the installation of the plug cover 200 can be ensured. Furthermore, the surface of the cock 220 is provided with annular sealing strips, which improves the sealing performance between the plug cover 200 and the ceramic filter element 100.
Two mounting holes are formed in the side wall of the ceramic filter element 100, wherein a back flushing pipe 500 is mounted in one mounting hole, and a sewage discharge pipe 600 is mounted in the other mounting hole. After ceramic filter core 100 used a period, the filter core internal surface was blockked up by the pollutant or the inside that the pollutant got into the filter core, and this moment with the backwash water pipe 500 connect on external water pipe, open tap, make the clear water get into the inside washing of filter core, the pollutant discharge that rethread blow off pipe 600 will wash down can realize ceramic filter core 100.
The end of the soil discharge pipe 600 preferably extends toward the bottom of the ceramic filter cartridge 100 so that contaminants can be more thoroughly discharged. In this embodiment, the reverse flushing pipe 500 and the sewage pipe 600 have a female connection end 510 at the end extending out of the inner cavity of the ceramic filter element 100, and the reverse flushing pipe 500 and the sewage pipe 600 need to be used in cooperation with a water inlet pipe or a water pumping pipe having a male connection end. When the water pumping pipe is used, the male connection head of the water inlet pipe or the water pumping pipe is inserted into the female connection head 510, and the quick connection between the water inlet pipe and the water pumping pipe can be realized. After connection, starting to perform back flushing on a valve of the water inlet pipe; after the back flushing is finished, closing the valve; then the pump connected with the water pumping pipe is opened for sewage discharge. After the sewage discharge is finished, the water inlet pipe or the water pumping pipe is pulled out, which is very convenient. Preferably, a rubber cover 520 is further provided on the coupling female 510. After the water inlet pipe or the water pumping pipe is pulled out, the rubber cover 520 is adopted to cover the connecting female head 510, so that the ceramic filter element 100 is prevented from being polluted.
