Sampling device for filter tank filler

Abstract

The invention provides a sampling device for filter tank filler. The sampling device includes an insert rod inserted into a filter tank, the lower end of the insert rod is provided with a sampling cylinder for acquiring filler of specific depth in the filter tank, the upper end cylinder port of the sampling cylinder is detachably connected to an openable cylinder cover, and the cylinder cover is connected to an opening structure. The sampling device for filter tank filler provided by the invention has the advantages that: during use, firstly the cylinder cover and the sampling cylinder are connected together, the cylinder port is plugged, the sampling device is inserted into the filter tank through the insert rod, when the sampling cylinder reaches a needed specific depth, the cylinder cover is opened by the opening structure, at the moment the filler of the depth can enter the sampling cylinder through the cylinder port, when the filler fills up the sampling cylinder, the sampling cylinder is pulled out of the filter tank through the insert rod, thus obtaining the filler of the specific depth. The sampling device has the characteristics of simple structure and convenient operation, can accurately collect filler of different depths in the filter tank, ensures the comprehensiveness and accuracy of the experimental analysis result, and is of important significance for judgment and scientific research of the actual production and operation state.

Description

technical field [0001] The invention relates to a sampling device for filter tank filler. Background technique [0002] Filters are commonly used treatment facilities in the process of drinking water and sewage treatment. According to the different treatment objects and functional requirements, they can be divided into three categories: filter filters, adsorption filters and biological filters. The principle of the filtration filter is that when the treated water passes through the granular filler (such as quartz sand, anthracite, ceramsite, blast furnace slag, plastic fiber ball, etc.) removal; the principle of the adsorption filter is to fill a certain amount of granular fillers (such as activated carbon, resin, etc.) In the late 1980s, a new type of biofilm sewage treatment technology emerged in European and American countries. The principle of the biofilter is to fill the filter with a certain amount of granular filler (such as ceramsite, coke, quartz sand, activated ca...

Problems solved by technology

[0005] With this kind of sampler, since the lower end of the whole tube body is open, when the sampler is pulled out, the stuffing in the tube body is easy to slide out under the action of gravity, especially the stuffing closest to the port, so that It is difficult to accurately obtain the filler at a specific depth, and it is impossible to o
