Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of sewage self-cleanse formula vent cabinet, as shown in Figure 1, including upper cabinet body 11, station 12 and lower cabinet body 13, upper cabinet body 11 are equipped with window 112 far from wall one side, and window 112 can pull up and down；Upper cabinet body 11 is equipped with exhaust fan 111, the top close to the upper cabinet body 11 of exhaust fan 111 offers ventilation opening 113.

The side in 12 face of station is provided with sink 121 and tap 122, the upper end opening and station 12 of sink 121 Upper surface flush, tap 122 is fixedly mounted at the one side edge position that sink 121 is connect with station 12.

The upper surface of station 12 is laid with aqueduct 123 along its edge position, and aqueduct 123 is anticorrosive property material Material is made, and aqueduct 123 is uniformly provided with several water-guiding holes 124 along its length, and water-guiding hole 124 is towards 12 side of station Inclination opens up.

As shown in Fig. 2, being equipped with water treatment facilities 131 in lower body cabinet, water treatment facilities 131 includes draining with sink 121 The level-one tank 2 of mouth connection, level-one tank 2 are located at the lower section of 121 discharge outlet of sink；Close to the bottom of level-one tank 2 Portion is communicated with sewage pump 21, and sewage pump 21 is communicated with reaction tank 3 far from 2 one end of level-one tank, connects close to the bottom of reaction tank 3 It is connected with fresh water pump 23, fresh water pump 23 is communicated with second level tank 5 far from 3 one end of reaction tank, close to the bottom of second level tank 5 It is communicated with suction pump 51, suction pump 51 is connected to far from 5 one end of second level tank with aqueduct 123.

The water outlet of sewage pump 21 is close to the top of reaction tank 3, and the water outlet of fresh water pump 23 is close to second level tank 5 Surface.

Filter screen 22 is fixed at the position being connected in level-one tank 2 with sewage pump 21.

The rear wall of lower cabinet body 13 is fixed with chemicals dosing plant 4, and chemicals dosing plant 4 is fixed on the lower cabinet of the back upper place of reaction tank 3 On 13 side wall of body.

Chemicals dosing plant 4 includes dosing pond 41 and control valve 42, control valve 42 close to the bottom in dosing pond 41, dosing pond 41 Medicine outlet is located at the surface in dosing pond 41.

As Figure 2-3, activated carbon filter layer 52 there are three being horizontally mounted in second level tank 5, activated carbon filter layer 52 Surrounding be bonded with the inner wall of second level tank 5, the successively equidistant arrangement from top to bottom of three activated carbon filter layers 52.

The liquid level sensor 43 of control sewage pump 21 and 42 start and stop of control valve is installed in level-one tank 2.

Second level tank 5 offers overflow port 53 close to its top side, and overflow port 53 is communicated with sewer pipe 54.

It the concrete operating principle of the present embodiment and has the beneficial effect that

When carrying out experimental implementation in vent cabinet, staff can directly be carried out laboratory sample from tap 122 is water-saving Dilution；A series of when tap 122 that is mounted in vent cabinet facilitates staff to carry out experimental implementation simultaneously are operated with water.

After the end of the experiment, when carrying out the cleaning of experimental ware, experimental ware is collected in screw clamp 121, staff It wears gloves, opens tap 122 and cleaned, water flows in level-one tank 2 from the discharge outlet of sink 121 first, when one When water level in grade tank 2 reaches certain altitude, control valve 42 and sewage pump 21 are opened, and filter screen 22 will be outstanding in water at this time Floating impurity intercepts, and water flows in reaction tank 3 under the action of sewage pump 21, while the medicament in dosing pond 41 starts injection reaction In pond 3, to which after the reaction was completed, the opening of fresh water pump 23, water flows to second level tank under the action of fresh water pump 23 in reaction tank 3 In 5, the suspended particulate in water is adsorbed by activated carbon filter layer 52 in secondary effluent pond, and water stores up in second level tank 5 It deposits.

When needing to carry out the cleaning in 12 face of station, directly suction pump 51 is opened, suction pump 51 is by second level tank Water in 5 is sent in aqueduct 123, and is sprayed from water-guiding hole 124, can carry out cleaning operation to station 12 at this time.

Reduce the harmful substance in water after treatment, when the water in second level tank 5 is more, extra water is straight It connects from overflow port 53 and is discharged in sewer pipe 54.

By effectively collecting the water after 122 cleaning experiment vessel of tap, it is handled, after processing Water on the one hand be directly discharged to will not to pollute the environment in sewer pipe 54, on the other hand can will after processing Water effectively uses, and is used for having saved water resource to a certain extent to the cleaning of 12 table top of station.

First recovery processing has been carried out by water of the level-one tank 2 to sink 121, the suspended impurity in water has been carried out just Walk intercept process.

The water to level-one tank 2 is subjected to the relevant harmful substance disposed in water by reaction tank 3, as in With the pH value of water.

By the way that by treated in reacted pond 3, water carries out purified treatment in second level tank 5, filter out some in water Suspended particulate.

Due to reducing the harmful substance in water, can be directly discharged in sewer pipe 54 after repeatedly handling, thus Reduce the pollution to water body.

Since the water in second level tank 5 is obtained after repeatedly being handled, so its water can be used for station The cleaning in 12 faces, has saved water resource to a certain extent.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
