Referring to Fig. 1 and Fig. 2, a kind of full-time sewage mixes sampling system, including filter device 10, full-time mixing sampling Structure and real-time sampling structure；

The filter device 10 is positioned close in the sewage water inlet pipe of coarse rack, and filter device 10 is hollow full encirclement Structure, and there are multiple inlet openings 11 thereon.

Filter device 10 in sewage water inlet pipe is tubular structure, and 10 length direction of filter device and water (flow) direction It is identical.Filter device 10 can also be other structures, for example can be the structures such as cuboid or square, why preferably this Tubular structure, being primarily due to sewage water inlet pipe is also tubulose, and filter device 10 is arranged in sewage water inlet pipe, the filtering of tubulose Device 10 and the contact of wastewater influent inside pipe wall are more, and frictional force is bigger, so that filter device 10 is not easy because of drainage flow And it moves.

Filter device 10 described in corrosion in water is made preferably with PVC material in order to prevent.

The diameter of the filter device 10 is 80-90mm, and 11 diameter of inlet opening thereon is 4-6mm.Due to self priming pump 20 It is to work for 24 hours, is on the one hand to guarantee that sewage is 24 hours combined sewages in real-time sampling cup 40, is on the other hand also Water inlet pipe 21 and outlet pipe 22 are blocked because of settlement of sewage in order to prevent；The diameter of filter device 10 is not easy to do too big, because For the too big flow velocity that may will affect sewage in sewage inlet pipe, result in blockage, can not be too small, if too small, filled into filtering The sewage set in 10 is too small, influences the work of self priming pump 20；As long as the diameter of inlet opening 11 is set as 4-6mm to be had in order to prevent Bits enter filter device 10, to be sucked by self priming pump 20, to cause self priming pump 20, subsequent pipeline and on-line sampling analysis The blocking of instrument.

The full-time mixing height of the sampling structure away from ground is higher than height of the real-time sampling structure away from ground；Due to height The presence for spending difference, the sewage into real-time sampling structure flow automatically by gravity, do not need to provide power again.

Full-time mixing sampling structure: including self priming pump 20, water inlet pipe 21, outlet pipe 22 and full-time sewage mixer 25；

Self priming pump full-time job in 2024 hours；The revolving speed of self priming pump 20 is adjustable, realizes in adjustment water inlet pipe 21 The speed of effluent flow rate, so as to adjust the sewage quantity in full-time sewage mixer 25.

The water inlet end of the water inlet pipe 21 is sealedly and fixedly connected with filter device 10, when it is implemented, water inlet pipe 21 into Water end (W.E.) is connect with filter device 10 using gluing, and the water outlet of water inlet pipe 21 is connected to the water inlet end of self priming pump 20, self priming pump 20 Water outlet be connected to the water inlet end of outlet pipe 22；

The full-time sewage mixer 25 is arranged in instrument cubicle, and has the first water inlet thereon；Full-time sewage Mixer 25 is made of nylon material.

First water inlet is connected to a water outlet of outlet pipe 22.

When it is implemented, having the first overflow port and the first drainage hole on full-time sewage mixer 25；

The height of first water inlet is lower than the first overflow port, the water inlet of first overflow port and the first overflow pipe 27 The water outlet of end connection, first overflow pipe 27 is connected to selection pond；Due to self priming pump full-time job in 2024 hours, hold Easily there is a situation where full-time sewage mixers 25 to fill, and the setting of the first overflow port can drain overflow sewage, guarantees instrument Sewage is not had between table to leave, guarantees instrument cubicle instrument running safety, while more guaranteeing production safety.

The bottom of full-time sewage mixer 25 is arranged in first drainage hole.Prevent full-time sewage mixer 25 Settlement of sewage, convenient for rinsing full-time sewage mixer 25 and blowdown.

Real-time sampling structure: including real-time sampling cup 40, exit branch 41 and the time relay；

There is the second water inlet on the real-time sampling cup 40；

The water inlet end of the exit branch 41 is connected to another water outlet of outlet pipe 22, the water outlet of exit branch 41 It is connected to the second water inlet；

When it is implemented, being generally also provided with the second overflow port and the second drainage hole on real-time sampling cup 40；

The height of second water inlet is lower than the second overflow port, and real-time sampling cup 40 is arranged in second drainage hole Bottom；Convenient for rinsing real-time sampling cup 40 and blowdown.

Second overflow port is connected to the water inlet end of the second overflow pipe 42, the water outlet of second overflow pipe 42 and choosing Select Chi Liantong, prevent once occur overflow appearance, guarantee production safety.

The exit branch 41 is equipped with electrically operated valve 43, and the electrically operated valve 43 controls on-off by the time relay. The exit branch 41 is hose, and the electrically operated valve 43 is electronic pinch valve.

Time relay control electrically operated valve on-off belongs to the prior art, therefore is not discussed in detail between the two herein Bus connection method.

The working principle of the full-time sewage mixing sampling system of the utility model is as follows:

Sewage enters sewage treatment plant by sewage water inlet pipe, before entering coarse rack, sets in sewage water inlet pipe Filter device 10 is set, self priming pump 20 starts, will be filtered by filter device 10 --- the filtering belongs to physical filtering, to sewage water Matter will not generate any influence, and the part of contaminated water that enter coarse rack at once is pumped into full-time sewage mixer 25, by Worked in self priming pump 2024 hours, therefore, what is stored in full-time sewage mixer 25 is 24 hours --- full-time sewage, On-line sampling instrument is sampled detection to the sewage in full-time sewage mixer 25, so as to adjust subsequent sewage treatment.It can According to revolving speed --- i.e. the control water inlet pipe 21 and water outlet of the amount adjustment self priming pump 20 of sewage in full-time sewage mixer 25 The flow velocity of sewage in pipe 22.

In sewage disposal process, it is also required to acquisition real-time sewage water sample sometimes, so, it is opened by the time relay electronic Valve 43, the effect automatic stream real-time sampling cup 40 of sewage intercepting well gravity flow, facilitates sampling.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
