Abstract

The utility model relates to a sewage sampling device. A pump body 2 and a pump cover 13 are fixedly connected by a screw 7 to form a flat U-shaped closed inner cavity. A flexible pipe 1 is arranged along the contour of the flat U-shaped closed inner cavity. Two ends of the flexible pipe 1 are extended from two circular holes 10. A rolling wheel component is positioned on the circular arc part of the flat U-shaped closed inner cavity. The rolling wheel component is fixedly connected with a motor shaft 6 by a circular hole 12 on a rolling wheel bracket 5. When a mini motor rotates, the rolling wheel component is driven by the mini motor to rotate, and flexible pipes positioned between a rolling wheel 3 and the cavity wall of the inner cavity of the pump body 2 are orderly compressed to form negative pressure. Sewage is sucked from one end of each of the flexible pipes, is discharged from the other end of each of the flexible pipes, and is discharged into a water storage container. The utility model has the advantages that the sewage only flows across the flexible pipes, and can not be contacted with the parts and the components of the sewage sampling device; the sewage sampling device has no corrosion and a few of faults.

Description

Sewage sampling device

The utility model relates to the sewage sampling apparatus.

Be accompanied by the high speed development of industry, problem of environmental pollution is on the rise, and especially water pollution issue seems even more important in the country that our water resource comparatively lacks.For this reason, State Bureau of Environmental Protection was just formulated the industrial sewage emission monitoring and has been taken over the relevant rules and the policy of charges for disposing pollutants at the eighties initial stage.

Composition and content for pollutant in the sewage of check discharging will carry out assay to the sewage water sample, and therefore, what at first run into is sewage sampling problem.

Traditional sampling method is hand sampling, and promptly the environment monitoring personnel regularly take water sample to the blowdown canal of factory with container, and this method of sampling falls behind, and it is very heavy to work.For addressing this problem, the factory that has has successively developed sample devices, and there are the water sample taking-up in the special container in a kind of waterwheel of picture Ancient Times in China, the water pocket on " waterwheel " when rotating; Another kind mainly is grouped into by vacuum pump, pipeline, valve body and electric control part.On technology and function, be better than the former, but the sewage pollution situation that domestic factory discharges is very serious, do not add any processing during discharging, the very strong acid of rod, cotton yarn, oils and corrosivity, alkali and harmful chemical are often arranged in the sewage, these materials cause the mechanical fault of equipment or make the very fast corrosion of equipment, its basic reason is the execution unit of this kind equipment such as valve body etc., isolates with sewage.

The purpose of this utility model provides a kind of execution unit and does not contact with sewage, thereby does not have the sewage sampling apparatus of sewage to operating part corrosion or stuck execution unit.

The utility model is achieved in that the sewage sampling apparatus comprises the pump housing, pump cover, flexible pipe and roll wheel assembly.The pump housing has a flat inner chamber, and the profile of inner chamber takes the shape of the letter U.The pump housing is screwed with pump cover and is connected.Connect the back and form a obturator with closed inner chamber.One end of this obturator has two circular holes, and flexible pipe penetrates from a circular hole, passes from another circular hole around a circle back along closed inner chamber.Roll wheel assembly is positioned at the circular arc position of closed inner chamber; Roll wheel assembly links to each other with micro-motor by the circular hole on it, and is fixed by a fixed pin.

During work, the micro motor for driving roll wheel assembly rotates in closed inner chamber, the flexible pipe of the roller backing on the roll wheel assembly between roller and pump housing inner chamber chamber wall, and flexible pipe one end, promptly water inlet end forms negative pressure, and sewage is flowed out along the flexible pipe rising and from the flexible pipe other end.The water inlet end of flexible pipe is loaded onto filtration unit and is placed on and pollutes in the canal, and the other end of flexible pipe is put into the water storage bottle, thereby finishes the sewage sampled functions.

Sewage is taken out from the blowdown canal to advancing in the water storage bottle only by acid and alkali-resistance, corrosion resistant flexible pipe, do not contact with other component in the device, thereby avoided pickup and the corrosion of sewage to this sampler, also avoided foreign matter that running gear is blocked, guarantee the normal operation of device, prolonged the serviceable life of equipment.

The utility model is described in further detail below in conjunction with embodiment shown in the drawings:

The sewage sampler comprises the pump housing 2, pump cover 13, flexible pipe 1, roll wheel assembly and micromotor 11.The pump housing 2 has a U-shaped profile inner chamber.Pump cover 13 is connected by screw 7 with the pump housing 1, forms a closed inner chamber, and flexible pipe 1 is put along closed inner chamber chamber wall cloth, and draw by two holes 10 on the pump housing 2, the pump cover 13 respectively at two ends.Roll wheel assembly is arranged in closed inner chamber, and cooperates with arch section.The motor shaft 6 of micromotor 11 links to each other with circular hole 12 on the roll wheel assembly, and fixed pin 8 inserts in the pin-and-hole of motor shafts by the aperture on the rolling wheel support 59, and motor shaft 6 and rolling wheel support 5 are connected.

Roll wheel assembly comprises rolling wheel support 5, roller 3, and roller 3 links to each other with rolling wheel support by roller shaft 4.

Flexible pipe 1 can be a silicone tube, also can be the rubber tube of oil resistant acid and alkali-resistance.
