Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, 2 and 4, a settling device for oily sludge comprises a separation bin 2, wherein a water collecting bin 3 with a water discharge port 3-1 and an oil collecting bin 4 with an oil discharge port 4-1 are respectively arranged at two ends of the separation bin 2, and the water collecting bin 3 and the oil collecting bin 4 can be communicated with the separation bin 2; the top of the separation bin 2 is provided with an oil scraper 5, the side edge of the separation bin is provided with a feeding hole 6, the bottom side of the separation bin is provided with a stirring mechanism 7, and the bottom of the separation bin 2 is connected with a slag discharge pipeline 2-1.
Specifically, the separation bin 2 is used for precipitating an oil-water-sludge mixture which enters the cavity through the feeding connecting pipeline 6-1 and along the feeding hole 6, and the oil-water-sludge mixture is layered by using physical characteristics (namely, different densities of main components) of substances, wherein the density conditions of the main substances are as follows:
rho oil > rho water > rho mud;
the delamination was as follows:
and (3) upper layer: an oil; middle layer: water; the lower layer: mud
And water and oil with obvious layers after precipitation are respectively collected through the water collecting bin 3 and the oil collecting bin 4, and simultaneously, sludge at the lower layer is stirred by a stirring mechanism arranged at the bottom of the separation bin 2 and then is discharged along the slag discharge pipeline 2-1. A water outlet 3-1 on the water collecting bin 3 can be connected with an external water pipe through a water drainage connecting pipeline 3-2; an oil discharge port 4-1 on the oil collection bin 4 can be connected with an external oil pipe through an oil discharge connecting pipeline 4-2.
In order to effectively collect the layered water and oil, the tops of the separation bin 2, the water collecting bin 3 and the oil collecting bin 4 are horizontal, and the purpose of collecting water can be achieved only by communicating the separation bin 2 with the water collecting bin 3 in the middle layer; the purpose of collecting the oil can be achieved only by communicating the separation bin 2 with the oil collecting bin 4 on the upper layer.
As shown in fig. 1 to 3, as an optimization of the present embodiment, a flow baffle 8 is installed at a position of the inner cavity of the separation bin 2 corresponding to the feed inlet 6; specifically, the flow baffle 8 can ensure that oil cement entering the separation bin 2 flows in more uniformly, so that the precipitation efficiency is ensured; preferably, the flow baffle plate 8 is fixed through a set of fender slots 14 arranged on the inner walls of the separation bin 2, a slot mode is adopted, the flow baffle plate 8 can be conveniently and smoothly taken, a handle 8-1 is arranged at the top of the flow baffle plate 8, two sides of the fender slots 14 are fixed with the inner walls through the reinforcing ribs 10, the upper end and the lower end of the fender slots 14 are connected with the feed inlet 6 through a set of baffles 15 to form a horn-shaped feed cavity, and therefore the mixture entering the separation bin 2 can be ensured to uniformly flow in after passing through the flow baffle plate 8.
In order to prevent oil on the upper layer from entering the water collecting bin 3, a compartment plate 9 is arranged between the inner cavity of the separation bin 2 and the inner cavity of the water collecting bin 3, so that water and oil can be effectively separated, and the compartment plate 9 and the flow baffle plate 8 are fixed through a reinforcing rib 10 arranged on the inner wall of the separation bin 2.
In this embodiment, the stirring mechanism 7 includes a paddle shaft 7-1 with a paddle 7-2 penetrating through the separation bin 2, and both ends of the paddle shaft 7-1 are fixed by a set of paddle shaft support plates 7-3 mounted on the outer wall of the separation bin 2 (if the box body 1 is provided outside the separation bin 2, the paddle shaft support plates 7-3 are fixed on the outer wall of the box body 1), and are driven by a motor 7-4 to rotate clockwise or counterclockwise. The stirring mechanism 7 is arranged to mainly prevent the sludge on the lower layer from being solidified after precipitation and being discharged smoothly, and the lower layer is continuously stirred to ensure that the sludge is not solidified and is beneficial to being discharged from the slag discharge pipeline 2-1.
As for the optimization of better sludge discharge, the bottom of the separation bin 2 is in an inverted triangle shape (at this time, the bottom of the separation bin 2 is fixed with the base of the box body 1 through a group of fixing frames), so as to form an inverted triangle cavity 2-2, the stirring mechanism 7 is positioned in the inverted triangle cavity 2-2, and the slag discharge pipeline 2-1 is positioned below the stirring mechanism 7. The bottom of the separation bin 2 is arranged to be an inverted triangle, an inverted roof or a cone, which is mainly beneficial to smoothly and downwards accumulating sludge under the emphasis of self gravity, and the mechanism 7 continuously stirs at the position, so that the sludge can be smoothly and strictly discharged from the slag discharge pipeline 2-1. In order to increase the sludge discharge efficiency, three slag discharge pipelines 2-1 are arranged at equal intervals on the side of the separation bin 2.
As the optimization of the automatic drainage of the water collecting bin 3, the position of the inner cavity of the water collecting bin 3 corresponding to the drainage port 3-1 is provided with the ball float valve 13, when the water level in the water collecting bin 3 reaches a certain height, the ball float valve 13 can be automatically opened, so that the water in the water collecting bin 3 can be smoothly drained along the drainage port 3-1.
As optimization of the oil collecting bin 4, in different environments, the proportion of main mixture in the oily water and sludge mixture to be treated is not certain, when the oily water and sludge mixture contains more oil, the oil layer on the upper layer after precipitation is thicker, and the larger the communication opening between the oil collecting bin 4 and the separation bin 2 is, the more favorable the oil collection is; however, when the oil content is low, the oil layer on the upper layer after the precipitation is thinner, and the smaller the communication opening between the oil collection bin 4 and the separation bin 2 is, the more favorable the oil collection is (the water in the middle layer is prevented from entering).
In view of the above, if a customized precipitation device is used for each proportion of the cement mixture, the cost is greatly increased and the complete use of the equipment is not facilitated. Therefore, in this embodiment, a limiting baffle 11 is further disposed between the oil collecting bin 4 and the separation bin 2, and the limiting baffle 11 can be driven to lift by an adjusting handwheel 12 disposed on the side wall of the box body 1. By means of clockwise or anticlockwise rotation of the adjusting hand wheel 12, a driven mechanism (such as a screw rod device, a hydraulic device and the like) is driven to drive the limiting baffle 11 to ascend or descend, and therefore the purpose of adjusting the size of a communication channel between the oil collecting bin 4 and the separating bin 2 is achieved. The device can be suitable for the precipitation and collection of oil-water-sludge mixtures with various proportions.
As shown in fig. 3, in order to facilitate transportation or placement and fixation of the device, a box body 1 is sleeved outside the separation bin 2, the water collection bin 3 and the oil collection bin 4, and supporting seats 16 which are symmetrical to each other are arranged along the bottom side of the box body 1.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
