Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, in particular to an oil collecting tank for oil-water separation in chemical production. Background Art

[0002] Chemical production refers to the chemical processing of raw materials to ultimately produce valuable products. Due to the diversity of raw materials and products and the complexity of production, tens of thousands of chemical production processes have been formed.

[0003] Oil collecting tanks usually separate oil and water by sedimentation. Due to the low density of oil, the oil will float on the top of the water flow. However, with the long-term use of the oil collecting tank, more oil stains will adhere to the inner wall. The existing oil collecting tanks do not have the function of cleaning. The staff is required to drain the oil and water inside and then clean the inner wall of the tank manually. This method is very harmful to the staff. Therefore, we proposed an oil collecting tank for oil-water separation in chemical production. Utility Model Content

[0028] Valves 113 are provided inside the drain pipe 111 and the oil drain pipe 112. The left side of the oil drain pipe 112 passes through the oil collecting tank 1 and extends to the inside of the separating ring 115. The outer surface of the oil drain pipe 112 is fixedly connected to the inner wall of the oil collecting tank 1. A diverter groove 114 is formed between the outer side of the separating ring 115 and the inner wall of the oil collecting tank 1. By providing the separating ring 115, the liquid will be precipitated in the separating ring 115, which will cause the separated water flow to move to the diverter groove 114, and the oil and water will float in the separating ring 115, which can reduce the mixing of the oil and the water flow and make the oil-water separation effect better. The oil is intercepted by the separating ring 115, which can reduce the oil stains adhering to the inner wall of the oil collecting tank 1.

[0033] A specific application of this embodiment is:

[0034] When in use, the chemical liquid is discharged into the oil collecting tank 1 through the liquid inlet pipe 11, and the oil and water will first stay in the separation ring 115. The liquid will settle in the separation ring 115, which will cause the separated water flow to move to the diverter groove 114, and the oil and water will float in the separation ring 115. The oil in the separation ring 115 can be discharged by opening the valve 113 on the oil discharge pipe 112, and the water flow in the diverter groove 114 can be discharged by opening the valve 113 on the drain pipe 111, which can reduce the mixing of oil and water flow and make the oil-water separation effect better. The oil is intercepted by the separation ring 115, which can reduce the oil stains attached to the inner wall of the oil collecting tank 1. When the inner wall needs to be cleaned, the oil and water in the oil collecting tank 1 are discharged first, and then the motor 131 is started to drive the belt pulley 1 132 to rotate. The belt pulley 1 132 drives the belt pulley 2 141 to rotate through the belt, and the rotating shaft 14 rotates together, and at the same time drives the fixing frame 142 to rotate. The cleaning rod 121 rotates together, and the rubber scraper 122 on the cleaning rod 121 will clean the inner wall of the separation ring 115, so that the oil stains fall to the bottom of the oil collecting tank 1. The cleaning rod 121 drives the scraper 124 to rotate through the connecting block 123, so that the scraper 124 scrapes off the oil stains at the bottom of the inner wall of the oil collecting tank 1. Since the bottom of the inner wall of the oil collecting tank 1 is conical, the oil stains can be concentrated on the drain pipe 15. Then, the turning handle 155 is turned counterclockwise to drive the threaded block 154 to rotate, and the sealing plug 151 moves downward. When the sealing plug 151 moves below the slag discharge port 152, the oil stains are discharged through the slag discharge port 152 on the drain pipe 15, and the diverter ring 153 guides the oil stains to be discharged, thereby completing the cleaning. There is no need for staff to enter the oil collecting tank 1 for cleaning, which protects the staff from injury. Finally, after the cleaning is completed, the turning handle 155 is turned clockwise to move the sealing plug 151 upward to seal the slag discharge port 152.
