Abstract
Description
Technical Field
[0001] The utility model relates to the field of wastewater treatment, in particular to an oil removal and separation device for treating phenol-containing wastewater. Background Art
[0002] Phenolic wastewater refers to wastewater containing phenolic compounds, which usually comes from wastewater discharge in industrial processes such as chemical production, oil refining, coal gasification, pharmaceuticals, printing and dyeing, and metallurgy. In the process of treating phenolic wastewater, it is necessary to pay attention to the oil-water separation operation of the phenolic wastewater to discharge the oil substances in the phenolic wastewater. Generally, the separation treatment is achieved by using the different densities of oil and water. During the static treatment process, the phenolic wastewater produces an obvious oil-water boundary line, and then the separated oil is extracted to achieve oil-water separation. However, when performing specific operations in the existing technology, it is difficult to accurately control the extraction volume, which will cause the separated water to be pumped in during oil extraction and separation, causing the oil and water to mix again, and due to the light refraction effect of the liquid, it is difficult for the operator to accurately locate the specific position of the dividing line.
[0003] Therefore, in order to solve the above problems, an oil removal and separation device for treating phenol-containing wastewater is now developed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing devices that it is difficult to accurately control the extraction volume during specific operations, which will cause the separated water to be pumped in during oil separation, causing the oil and water to mix again, and due to the light refraction effect of the liquid, it is difficult for the operator to accurately locate the specific position of the dividing line, the utility model provides an oil removal and separation device for treating phenol-containing wastewater.
[0005] The technical solution of the utility model is: an oil removal and separation device for treating phenol-containing wastewater, comprising a separation frame, an infrared distance sensor is installed on the front of the separation frame, a fixing piece is installed on the front wall inside the separation frame by bolts, a floating plate assembly is slidably connected to the fixing piece, a liquid extraction port is opened on the top of the separation frame, a water inlet is opened on the front right side of the separation frame, and an isolation mechanism is provided on the separation frame.
[0006] Furthermore, the isolation mechanism includes an electric push rod, the electric push rods are connected to the left and right sides of the separation frame, the telescopic ends of the electric push rods are connected to fixed plates, and isolation frames are connected between the fixed plates.
[0007] Furthermore, a heating mechanism is included, which includes a power supply. The power supply is installed on the upper rear side of the separation frame. Wires are connected to the left and right sides of the power supply. The wires are connected to heating elements, and the heating elements are connected to the rear of the isolation frame.
[0008] Furthermore, the floating plate assembly is made of aluminum metal, which has a density less than water and greater than oil.
[0009] Furthermore, the isolation racks are connected with a plurality of inclined plates for filtering and isolation.
[0010] Furthermore, the heating element is provided with a waterproof cover.
[0011] By adopting the above technical solution, the beneficial effects of the utility model are:
[0012] 1. The utility model automatically judges the standing result of phenol-containing wastewater through a floating plate assembly made of aluminum metal. After the preliminary separation of oil and water in the phenol-containing wastewater is completed, an isolation frame is used to physically separate the oil and water according to the detected oil-water separation surface height, thereby avoiding pumping out water during the oil pumping process and improving the accuracy of oil removal and separation.
[0013] 2. When the utility model is performing stationary oil-water separation of phenol-containing wastewater, the power supply is started to cause the heating element to begin to generate heat, thereby accelerating the molecular movement speed in the phenol-containing wastewater, allowing the oil and water to be separated quickly, thereby improving the efficiency of oil-water separation of phenol-containing wastewater.

DETAILED DESCRIPTION
[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0020] Example 1
[0021] An oil removal and separation device for treating phenol-containing wastewater, such as Figure 1 and Figure 2As shown, it includes a separation frame 1, an infrared distance sensor 2 is installed on the front of the separation frame 1, a fixing part 3 is installed on the inner front wall of the separation frame 1 by bolts, a floating plate assembly 4 is slidably connected to the fixing part 3, the floating plate assembly 4 is made of aluminum metal, and its density is less than water and greater than oil. A liquid extraction port 5 is opened on the top of the separation frame 1, a water inlet 6 is opened on the right front side of the separation frame 1, and an isolation mechanism 7 for separating and blocking oil and water is provided on the separation frame 1.
[0022] like Figure 1 and Figure 3 As shown, the isolation mechanism 7 includes an electric push rod 71, and the electric push rods 71 are connected to the left and right sides of the separation frame 1. The telescopic ends of the electric push rods 71 are both set to face upward, and fixed plates 72 are connected to the telescopic ends of the electric push rods 71. Isolation frames 73 for separating oil and water are connected between the fixed plates 72, and the isolation frames 73 are connected to multiple inclined plates for filtering and isolation.
[0023] It should be noted that when treating phenol-containing wastewater, the present device can be used. First, the phenol-containing wastewater is input into the separation frame 1 through the water inlet 6. As the wastewater enters the separation frame 1, the float assembly 4 will move upward due to the buoyancy of the wastewater. At this time, the infrared distance sensor 2 will detect the height change of the buoyancy assembly. After that, the wastewater begins to stand still and oil-water separation occurs. Since the float assembly 4 is made of aluminum metal, its density is less than that of water but greater than that of oil. Therefore, after the wastewater produces oil-water separation, the float assembly 4 will start to move downward until it moves to the oil-water separation point. When it leaves the surface, it stops moving. At this time, the position of the floating plate assembly 4 is detected by relying on the infrared distance sensor 2. When it is found that the floating plate assembly 4 moves downward and does not continue to move within a certain period of time, it means that the preliminary oil-water separation of the static wastewater is completed. At this time, the electric push rod 71 is controlled according to the distance data obtained by the infrared distance sensor 2, so that the fixed plate 72 drives the isolation frame 73 to move to the corresponding height, and the oil and water are physically isolated. Finally, the pumping pipe is inserted into the liquid extraction port 5, and then the pumping equipment is started to extract the oil to achieve the effect of oil removal and separation.
[0024] Example 2
[0025] On the basis of Example 1, Figure 1 and Figure 4 As shown, a heating mechanism 8 is also included, and the heating mechanism 8 includes a power supply 81. The power supply 81 is installed on the upper rear side of the separation frame 1. Wires 82 are connected to the left and right sides of the power supply 81. The wires 82 are connected to heating elements 83. The heating elements 83 are connected to the rear of the isolation frame 73, and the heating elements 83 are provided with a waterproof cover.
[0026] It should be noted that when the phenol-containing wastewater is subjected to static oil-water separation, starting the power supply 81 causes the heating element 83 to begin to generate heat, thereby accelerating the molecular movement speed in the phenol-containing wastewater, allowing the oil and water to be separated quickly, thereby improving the efficiency of oil-water separation of the phenol-containing wastewater.
