Abstract

A sewage sampler which consists of a liquid fetching head, a fluid conveying tube, a solution bottle and a unidirectional suction balloon is characterized in that the port of the solution bottle is inserted with a cork. A guide pipe is inserted vertically in the center of the cork. The unidirectional suction balloon is inserted vertically in the guide pipe. The periphery of the solution bottle is equipped with an air inlet short section, which is connected with a soft tube of which the bottom end is equipped with the liquid fetching head. The liquid fetching head is conical, the periphery id equipped with liquid inlet port, and the soft tube is marked with scales.

Description

The sewage sampler

One, technical field

The utility model relates to a kind of portable sewage sampler, can take a sample to the sewage of different depth, can also measure water sludge interface height in the cesspool.

Two, background technology

At present, in environmental monitoring and water treatment, generally with pump be sampling power to the water quality sampling of different depth, sample devices is complicated heavy, away from the more apparent inconvenience in power supply place.In sewage treatment plant, be by the mensuration of water sludge interface height and sludge concentration in the settling basin is controlled sludge reflux pump, so that obtain suitable sludge back flow quantity.Regularly rotatablely move owing to scrape mud in the settling basin, thereby solid mechanical formula water sludge interface determinator should not be set in the pond as circumference.The open report in " reuse (second edition) is disposed in waste water engineering, processing " [in June, 1986 Chinese translation first published] book according to U.S. Metcalfe and Ai Di company: the operation of sludge reflux pump is to control by a series of photoelectric tubes or the acoustic shock system that is located in the settling basin, this quasi-instrument complex structure, involve great expense, inconvenient maintenance, thereby limited its widespread use, domestic also little this quasi-instrument of use.

Three, summary of the invention

The purpose of this utility model provides a kind of sewage sampler.It can be easily in the settling basin such as river course, pond, lake, shallow sea and sewage treatment plant, water quality to different depth is sampled, simultaneously also available it correctly measure water sludge interface height and sludge concentration, control sludge reflux pump according to measurement result, so that obtain suitable sludge back flow quantity.

The utility model is made up of liquid taking head, woven hose, solution bottle and one-way intake ball, it is characterized in that the solution bottleneck inserts a cork, the cork central vertical is plugged in a conduit, vertical slotting one-way intake ball on the conduit, be provided with an air intake opening pipe nipple in all sides of solution bottle, be connected to the flexible pipe that a foundation end has liquid taking head on the pipe nipple; Liquid taking head is taper, and all sides are provided with inlet, indexing on the flexible pipe.

The utility model is simple in structure, volume is little, use in light weight, simple, convenient.

Five, embodiment

The utility model is based on negative pressure imbibition principle and designs, and is made up of liquid taking head 1, woven hose 2, solution bottle 3 and one-way intake ball 4.Solution is: when 1. being used for the sewage sampling: at first woven hose is applied malleation, material emptying in will managing, in order to avoid before sampling, be mixed with the water sample of different depth in the pipe, when treating that liquid taking head arrives required sampling depth, again woven hose is applied negative pressure, the water sample of this degree of depth just is inhaled in the bottle, thereby reaches the sampling purpose; When 2. being used for determining the water sludge interface height: constantly change the water sample that liquid taking head is drawn in the position and the observation post of sewage, when liquid taking head is positioned at the mud layer of water sludge interface just, the water sample that sucts is muddy, at this moment by the just height of water sludge interface as can be known of institute's target yardstick on the woven hose.Imposing malleation or negative pressure to woven hose is to bring in realization by changing the one-way intake ball with being connected of sampling thief, and the degree of depth of sampling can be read by the yardstick on the woven hose.

Claims

1, a kind of sewage sampler, form by liquid taking head, woven hose, solution bottle and one-way intake ball, it is characterized in that the solution bottleneck inserts a cork, the cork central vertical is plugged in a conduit, vertical slotting one-way intake ball on the conduit, be provided with an air intake opening pipe nipple in all sides of solution bottle, be connected to the flexible pipe that a foundation end has liquid taking head on the pipe nipple; Liquid taking head is taper, and all sides are provided with inlet, indexing on the flexible pipe.
