DETAILED DESCRIPTION

[0025] By adopting the above technical solution, when the shaft 3 rotates, the transmission gear 4 can drive the chain 5 to transmit, and under the action of the stop rod 7, the stop rod 7 will abut against the skimming plate 6 to slowly move across the upper surface of the wastewater, drive the foam in the wastewater pool 1 to move to the right, and gradually pour the foam and part of the liquid into the backflow pool 82 along with the transmission of the chain 5. By adding the bottom liquid into the backflow pool 82 and controlling the transmission speed, when the foam and the liquid reach the backflow pool 82, the foam will float into the skimming pool 101 due to the fact that the foam floats on the surface of the liquid, and the excess liquid will flow back to the wastewater pool 1 through the backflow valve pipe 83. This design can clean the foam and reduce the outflow of the liquid in the wastewater pool 1.

[0026] As shown in Figure 1 , Figure 2 , Figure 4As shown, the outer surface of the fixing plate 2 is provided with a positioning plate 9, and the fixing plate 2 is fixedly connected to the outer surface of the wastewater tank 1 by screws.

[0027] Furthermore, a first pulley 10 is fixedly connected to one end of the shaft 3, and a motor 11 is installed on the left side of the wastewater tank 1. A second pulley 12 is fixedly connected to the output end of the motor 11, and the first pulley 10 and the second pulley 12 are connected by a belt.

[0028] Furthermore, a first fixing screw 13 is welded to the outside of the chain 5, and two first ear plates 14 are fixedly connected to the upper surface of the descaling plate 6. The first ear plates 14 are fixedly connected to the outer circular surface of the first fixing screw 13 by nuts. The descaling plate 6 can be disassembled by removing the first ear plates 14 fixed to the first fixing screw 13.

[0029] Furthermore, the outer surfaces of both sides of the reflux pool 82 are fixedly connected with second ear plates 15, and the surface of the second ear plates 15 is provided with preset holes.

[0032] Working Principle: When using this petrochemical wastewater adsorption and sedimentation device, firstly, when the shaft 3 of this device rotates, the transmission gear 4 drives the chain 5 for transmission. Under the action of the push rod 7, the push rod 7 will push against the foam discharge plate 6 and slowly slide across the upper surface of the wastewater, causing the foam inside the wastewater tank 1 to move to the right. Gradually, with the transmission of the chain 5, the foam and some liquid are poured into the return tank 82. By adding bottom liquid to the return tank 82 in advance and controlling the transmission speed, after the foam and liquid reach the return tank 82, since the foam floats on the liquid surface, the foam will float into the foam receiving tank 101. The excess liquid brought in will flow back into the wastewater tank 1 through the return valve pipe 83. The positioning plate 9 can achieve the effect of positioning and overlapping when installing the fixing plate 2. Through the transmission of the motor 11 and the pulley, it is convenient to separate the first pulley 10 and the second pulley 12. This is the working principle of the petrochemical wastewater adsorption and sedimentation device.
