Abstract
The utility model provides a sewage pre-treatment device which comprises a water storage tank and a controller; the water storage tank body is provided with a water inlet, a water drainage port, a sampling port and a vent; the water inlet is arranged at the upper part or on the top of the tank body, the water drainage port is arranged at the bottom of the tank body, and the sampling port is arranged at the bottom or the lower part of the tank body; a water inlet valve is arranged at the water inlet, and a water drainage valve is arranged at the water drainage port; the water inlet valve and the water drainage valve are respectively connected with the controller; the controller controls the on and the off of the water inlet valve and the water drainage valve; an appropriate position on the inner wall of the water storage tank is also provided with a liquid level sensor; and the liquid level sensor transmits detected liquid level signals to the controller. The sewage pre-treatment device pre-samples the stored water through a thick pipeline, and can effectively solve the problems that a sampling pipeline is easy to block and the entering water is not uniform.
Description
Technical field
The utility model relates to a kind of sewage pretreatment unit, relates in particular to a kind of pretreatment unit of using in sewage sampling and the testing process of being adapted at.
Background technology
At present, known enviromental monitoring equipment all needs earlier sewage to be taken a sample when carrying out sewage detection, and still, the sewage sampling line of existing sewage sample apparatus is generally very thin, pipeline very easily gets clogged, if adopt the direct water intaking of pressure piping then can cause into water inequality.
The utility model content
In order to overcome the above-mentioned defective of existing sewage sample apparatus, the utility model provides a kind of sewage pretreatment unit and water tank thereof, can effectively solve the problem that the stopple coupon Louis is blocked and water inlet is uneven.
For this reason, the utility model adopts following technical scheme:
A kind of water tank of sewage pretreatment unit is provided, is provided with water inlet, freeing port, sample tap and exhausr port on tank body, water inlet is positioned at the top or the top of tank body, and freeing port is positioned at tank base, and sample tap is positioned at the bottom or the bottom of tank body.
The top of described tank body is provided with overflow vent.
A kind of sewage pretreatment unit is provided, comprise water tank and controller, on the water tank tank body, be provided with water inlet, freeing port, sample tap and exhausr port, water inlet is positioned at the top or the top of tank body, freeing port is positioned at tank base, sample tap is positioned at the bottom or the bottom of tank body, be provided with water intaking valve in the water inlet, the freeing port place is provided with draining valve, water intaking valve links to each other with controller respectively with draining valve, closing and opening of controller control water intaking valve and draining valve also is provided with liquid level sensor in the appropriate position of water tank inwall, and this liquid level sensor passes to controller with the liquid level signal that detects.
Described water tank tank body is provided with overflow vent, and this overflow vent is positioned at the liquid level sensor top.
Compare with existing direct employing sewage sampling pipe sampling, adopt the utility model as a kind of pre-processing device in sewage sampling and the testing process, be equivalent to increase the operation of taking a sample together, and this road sampling operation adopts thicker water inlet pipe and water outlet pipe and water tank to finish retaining to take a sample in advance, stopple coupon by the sample tap sampling, can effectively be avoided pipe blocking again; And for the pressure piping water intaking, the effectively pressure release of this device is to keep constant voltage; In the liquid level sensor of dress then can be in time flooded condition in controller feedback water tank, intake by controller control then.Adopt polluted water pretreatment apparatus of the present utility model, can compensator or trimmer pressure pipeline sewage and other states under sewage, keep the accuracy of instrument sampling.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a kind of sewage pretreatment unit of the utility model embodiment.
Embodiment
Referring to accompanying drawing.The sewage pretreatment unit of present embodiment comprises water tank and controller 20, on water tank tank body 10, be provided with water inlet 11, freeing port 12, sample tap 13, exhausr port 14, overflow vent 15 and liquid level sensor 16, water inlet is positioned at the top of tank body, freeing port is positioned at tank base, and sample tap is positioned at the position near tank base.Water inlet 11 external pressure pipings, exhausr port 14 and atmosphere are communicated with, and are used for keeping jar internal gas pressure to stablize and carry out pressure release under extreme case.Overflow vent 15 is positioned at liquid level sensor 16 tops, is used for carrying out overflow under the situation that liquid level sensor 16 is not worked or freeing port 12 is stopped up, and sample tap 13 is used for the stopple coupon water intaking.
Be provided with water intaking valve 17 in the water inlet, the freeing port place is provided with draining valve 18, and water intaking valve and draining valve are electrovalve, and water intaking valve links to each other with controller respectively with draining valve, closing and opening by controller control water intaking valve and draining valve.Under duty not, draining valve often leaves, and is used for the water in the drain tank, drain shut valve during sampling, and a water is for sampling in jar.
The principle of work of present embodiment sewage pretreatment unit is as follows: water intaking valve is opened in controller control, rely on the water inlet of pressure piping self pressure, earlier tank body is carried out prerinse, finish, controller control drain shut valve when tank body cleans, water tank begins formally to carry out retaining, when liquid level sensor detected liquid level signal, liquid level sensor passed to controller with liquid level signal, was closed by controller control water intaking valve, then, stopple coupon is fetched water from sample tap.
