Description

Technical Field

[0001] The utility model relates to the technical field of chemical water-oil separation, in particular to a water-oil separation device for chemical machinery. Background Art

[0002] In the chemical industry, oily wastewater generated by chemical machinery enters into mechanical equipment such as pipes, pumps, and heat exchangers, which will reduce the efficiency of the equipment, resulting in reduced heat transfer efficiency, reduced pumping capacity, and increased equipment wear. Oil deposition can also cause scaling and blockage inside the equipment, increase maintenance frequency and costs, and in severe cases, cause equipment failure and shutdown, affecting the normal operation of the entire production line. Direct discharge without treatment will cause serious pollution to the environment, especially damage to the aquatic ecosystem. Oil pollution will inhibit dissolved oxygen in the water and affect the survival of aquatic organisms. At the same time, the oil film covering the water surface will hinder gas exchange and aggravate the deterioration of water quality.

[0003] In the process of treating oily wastewater, water-oil separation is a key step. The existing water-oil separation devices used in chemical machinery have serious problems with low separation efficiency. Due to the complexity of the oil-water mixture, including the wide distribution of oil droplet sizes, severe emulsification, and low oil-water interfacial tension, the separation process between oil droplets and water molecules becomes difficult and time-consuming. Slow separation not only affects the treatment efficiency, but also causes excessive load on subsequent treatment units, affecting the stable operation of the entire sewage treatment system. In addition, the traditional water-oil separation device has poor separation effect, resulting in the discharge of wastewater failing to meet statutory standards. Utility Model Content

[0023] The utility model adds the oil-water mixture into the separation box 3, and after standing, the oil and water will be stratified. The operator can observe the position of the oil pumping hard pipe 13 through the visual window 15 according to the oil storage amount, and then start the driving motor 7. Since the limit groove 6 limits the lifting plate 9, the threaded rod 8 drives the lifting plate 9 to move downward, and the lifting plate 9 drives the connecting rod 10 to move downward, thereby driving the oil pumping hard pipe 13 to move downward, so that the lower end of the oil pumping hard pipe 13 moves to the critical point between the water and the oil, and then starts the oil pump 12, so that the oil pump 12 transports the oil to the inside of the oil storage tank 4 through the oil guide hard pipe 14. After the oil is pumped out, since the lower end of the oil pumping hard pipe 13 does not contact the water, when the oil pump 12 continues to work, the water will not be pumped into the inside of the oil storage tank 4, which is easy to control and avoids the situation where the water dilutes the oil.

After standing, the oil and water will be stratified. The operator can observe the position of the oil pumping hard pipe 13 through the visual window 15 according to the oil storage, and then start the driving motor 7. Since the limit groove 6 limits the lifting plate 9, the threaded rod 8 drives the lifting plate 9 to move downward, and the lifting plate 9 drives the connecting rod 10 to move downward, thereby driving the oil pumping hard pipe 13 to move downward, so that the oil pumping hard pipe The lowermost end of 13 moves to the critical point of water and oil, and then the oil pump 12 is started, so that the oil pump 12 transports the oil to the inside of the oil storage tank 4 through the oil guide tube 14. After the oil is pumped out, since the lower end of the oil pump tube 13 does not contact the water, when the oil pump 12 continues to work, the water will not be pumped into the inside of the oil storage tank 4, which is convenient for control and avoids the situation where the water dilutes the oil. Finally, the control valve 20 is opened to discharge the oil in the oil storage tank 4 through the oil drain pipe 19 for convenient unified collection.
