Abstract
The utility model discloses a kind of water quality online analyzer pretreatment unit, comprise storage sample device, the first filter screen, the second filter screen, the first water intaking valve, the second water intaking valve, the second outlet valve, the first outlet valve and pressure regulator valve, compared with prior art, the utility model adopts bilateral water inlet, bi-directional filtered, alternately switching, thus the automatic cleaning realized screen pack, achieve use and once clean target once, the problem that can effectively prevent screen pack from blocking.Cleaning used medium is the water sample after filtering, and can not expend tap water, can not cause secondary pollution, can lower human cost simultaneously.This device adopts disconnecting relay to realize steering logic, does not need PLC dispatch control system, can reduce the cost and failure rate.
Description
Technical field
The utility model relates to a kind of environmental protection water monitoring device, particularly relates to a kind of water quality online analyzer pretreatment unit.
Background technology
At field of Environment Protection, the data accuracy of pollution source water quality online automatic monitor device is most important, and it is the sole indicator evaluating prevention and control of pollution source facility regulation effect.
But, the data accuracy of pollution source water quality online automatic monitor device is but subject to the impact of many factors, wherein the most outstanding is the impact of water sample on analysis result, main impact derives from the impurity in water sample, impurity can cause line clogging, sampling is forbidden, thus impact analysis result.Solution general at present installs water sample preprocessing apparatus additional, and the principle of work of pretreatment unit adopts the mode of physics to filter.
The shortcoming that current pretreatment unit exists: screen pack often blocks, and also different by sampled point operating mode difference blocking frequency, and time serious, blocking in a day is several times, needs human at periodic intervals to clear up or uses tap water timing back flush.
Human at periodic intervals clears up Problems existing: waste time and energy, and cost is higher, once periodic Control is bad or the sudden change of sampled point operating mode, screen pack all can be caused to block, and analyser is got less than water sample, thus occurs instrument failure or occur wrong analysis result.
Problems existing is rinsed in tap water timing: expend precious tap water resource and cause secondary pollution, pipeline residual tap water and pollution source water sample may be caused to mix thus impact analysis result, and timing automatic Back Washing Control System complexity can increase possible failure rate.
Utility model content
The purpose of this utility model is just to provide a kind of water quality online analyzer pretreatment unit to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises storage sample device, first filter screen, second filter screen, first water intaking valve, second water intaking valve, second outlet valve, first outlet valve and pressure regulator valve, described storage sample device is series between the first end of described first filter screen and described second filter screen, second end of described first filter screen is connected with the first end of described first water intaking valve and described second outlet valve simultaneously, second end of described second filter screen is connected with the first end of described second water intaking valve and described first outlet valve simultaneously, second end of described first water intaking valve is connected with the second end of described second water intaking valve and the first end of described pressure regulator valve and as water inlet pipe simultaneously, second end of described pressure regulator valve is connected with the second end of described second outlet valve and described first outlet valve and as rising pipe simultaneously.
The beneficial effects of the utility model are:
The utility model is a kind of water quality online analyzer pretreatment unit, compared with prior art, the utility model adopts bilateral water inlet, bi-directional filtered, alternately switching, thus the automatic cleaning realized screen pack, achieve use and once clean target once, the problem that can effectively prevent screen pack from blocking.Cleaning used medium is the water sample after filtering, and can not expend tap water, can not cause secondary pollution, can lower human cost simultaneously.This device adopts disconnecting relay to realize steering logic, does not need PLC dispatch control system, can reduce the cost and failure rate.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises storage sample device 1, first filter screen 2, second filter screen 3, first water intaking valve 4, second water intaking valve 5, second outlet valve 6, first outlet valve 7 and pressure regulator valve 8, storage sample device 1 is series between the first filter screen 2 and the first end of the second filter screen 3, second end of the first filter screen 2 is connected with the first end of the first water intaking valve 4 and the second outlet valve 6 simultaneously, second end of the second filter screen 3 is connected with the first end of the second water intaking valve 5 and the first outlet valve 7 simultaneously, second end of the first water intaking valve 7 is connected with the second end of the second water intaking valve 5 and the first end of pressure regulator valve 8 and as water inlet pipe 9 simultaneously, second end of pressure regulator valve 8 is connected with the second end of the second outlet valve 6 and the first outlet valve 7 and as rising pipe 10 simultaneously.
As shown in Figure 1: the utility model has two kinds of mode of operations:
Pattern one: the first water intaking valve 4 and the first outlet valve 7 are opened, and the second water intaking valve 5 and the second outlet valve 6 are closed; Water sample stream is first water intaking valve 4 → the first filter screen 2 → storage sample device 1 → the second filter screen 3 → the first outlet valve 7, now utilizes the first filter screen 2 to filter water sample and carries out back flush to the second filter screen 3 simultaneously.
Pattern two: the first water intaking valve 4 and the first outlet valve 7 are closed, and the second water intaking valve 5 and the second outlet valve 6 are opened; Water sample stream is second water intaking valve 5 → the second filter screen 3 → storage sample device 1 → the first filter screen 2 → the second outlet valve 6, now utilizes the second filter screen 3 to filter water sample and carries out back flush to the first filter screen 2 simultaneously.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
