Description

TECHNICAL FIELD

[0001] The utility model belongs to wastewater treatment technical field, and specifically relates to a wastewater treatment supporting slag removal and oil separation equipment. BACKGROUND

[0002] In the industrial production field, the waste residue and waste oil in part of industrial wastewater are too much, which can easily cause the internal blockage of the equipment or pollute the internal instruments, meters and fillings of the equipment, so that the wastewater treatment equipment cannot work normally. Therefore, the wastewater with too much waste residue and waste oil needs to be pretreated, and the waste residue and waste oil in the wastewater are removed before being sent into the wastewater treatment equipment, so that the waste residue and waste oil can be prevented from directly entering the equipment to cause equipment failure.

[0003] At present, the traditional waste residue and waste oil removal technology is generally to dig an oil separation tank underground, and the waste water is sent into the oil separation tank for oil separation and residue removal. However, this treatment method of digging an oil separation tank needs a large treatment site and occupies a large area, and the waste residue and waste oil are also easy to cause blockage, which needs to be cleaned regularly by manual work, which is time-consuming and laborious. Therefore, a wastewater treatment supporting slag removal and oil separation equipment is designed to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the utility model and facilitating the understanding of the technical personnel in the field. The above technical scheme cannot be considered as known by the technical personnel in the field only because it is described in the background technology part of the utility model.

The water production tank and the isolation groove are separated by a second partition plate, and the height of the second partition plate is lower than that of the first partition plate.

[0041] Working principle:

[0042] Removal of large particle impurities: cooperate with the control system, set the liquid level control water inlet pump 17 start-stop condition in the waste liquid barrel. When the liquid level of the waste liquid barrel does not reach the low position, the water inlet pump 17 is started regularly, and the waste liquid enters the pre-filter 20, and the large particle impurities in the waste liquid are intercepted through the pre-filter 20.

[0043] The small-particle impurities are removed: the water inlet pump 17 draws the waste liquid with the large-particle impurities removed in the pre-filter 20 into the oil separation groove 2 of the treatment tank 1, the oil separation groove 2 is arranged with the multi-layered deslagging plate 5, the deslagging plate 5 is arranged in an inclined manner, the waste liquid passes through the small-size through holes on the deslagging plate 5, the water flows through the through holes and reaches the lower side of the deslagging plate 5, and the small-particle impurities are intercepted by the deslagging plate 5 and flow into the slag collecting groove 7 along the inclined surface of the deslagging plate 5, the slag discharging port 8 of the slag collecting groove 7 is provided with the slag discharging valve 9, and the slag discharging valve 9 is opened regularly to discharge the slag.

[0044] The floating oil is removed: after the waste liquid passes through the deslagging plate 5, the water flows into the intermediate layer below the deslagging plate 5, and the small-particle impurities flow into the slag collecting groove 7. Since the density of the water is greater than that of the oil, the oil floats to the upper layer to reach the oil separation plate 6, the oil separation plate 6 increases the separation area, the small oil droplets collide with the oil separation plate 6 and gather into large oil droplets, and then float and gather on the top of the oil separation groove 2, and with the increase of the floating oil, the floating oil overflows to the oil collecting groove 10 through the oil overflow port 11, and after the floating oil is separated, flows to the waste oil collecting barrel through the oil discharging port 12.

[0045] The treated waste water is discharged: after the oil-containing waste water passes through the deslagging plate 5 and the oil separation plate 6, there may still be some small-particle impurities that are not completely removed, the water flows from the intermediate layer into the isolation groove 3 through the communication port 14, and when the water level reaches the top of the isolation groove 3, the water overflows to the water production groove 4 through the second baffle 15, and the small-particle impurities are deposited at the bottom of the isolation groove 3. The water production groove 4 is provided with a connecting rod floating ball liquid level meter, and when the liquid level in the water production groove 4 reaches a high level, the water pump 19 automatically operates to draw the treated waste water in the water production groove 4 to the relay barrel for next step treatment work.
