Description

Technical Field

[0001] The utility model relates to the technical field of waste mineral oil separation, and specifically relates to a sedimentation separation device for waste mineral oil. Background Technique

[0002] Waste mineral oil is the oil that has been replaced when it can no longer be used due to being contaminated by impurities, oxidized and heated, and its original physical and chemical properties have changed. It mainly comes from the oil sludge and oil feet generated during oil exploration and refining; the precipitates generated during the storage of mineral oil; the replacement oil of machinery, power, transportation and other equipment, and the oil residues and filter media during the regeneration process. During the exploration, processing and use, due to the action of external factors, the original physical and chemical properties of the mineral oil have changed and it can no longer be used.

[0003] When optimizing the existing sedimentation separation equipment for waste mineral oil, most of them are reflected in how to effectively improve the dehydration rate of emulsified water and improve work efficiency. For example, the Chinese utility model patent with the application number CN201720449717.3 discloses "A Separation Emulsified Water Equipment for Waste Mineral Oil". In this device, a bracket is arranged at the bottom of the equipment body, a shell is arranged above the bracket, the upper half of the shell is a heating chamber, and the lower half is a sedimentation device. A heating resistor is arranged on the inner wall of the heating chamber, a feed inlet is arranged at the top of the heating chamber, and a sedimentation device is arranged at the bottom of the heating gun. A communicating pipe is arranged inside the sedimentation device, including a feed pipe, a water inlet pipe and a milk extraction pipe. By separating the emulsified water in the waste mineral oil, the separation process is simple, and by heating the oil-water mixture and adding a demulsifier, the dehydration rate of the emulsified water is effectively improved, the work efficiency is improved, and the practicability is strong.

[0004] Although the above sedimentation separation equipment for waste mineral oil has certain advantages in how to effectively improve the dehydration rate of emulsified water and improve work efficiency, it still has certain drawbacks: Since waste mineral oil contains water and impurities, after stratification in the sedimentation separation equipment, personnel manually separate the oil and water respectively. However, at the edge of the water-oil stratification layer, the water and oil are not in a static state, resulting in easy water-oil mixing during the separation process, which affects the separation efficiency.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides a sedimentation and separation device for waste mineral oil, having the following beneficial effects:

[0018] 1. For this sedimentation separation equipment for waste mineral oil, open the top cover, pour the waste mineral oil to be sedimented and separated into the interior of the sedimentation separation tank, cover the top cover, connect the oil extraction pipe to the oil outlet, let the waste mineral oil stand in the sedimentation separation chamber for sedimentation. Since the density of water is greater than that of oil, the water body can sink downward through the sieve openings under gravity, and the impurities in the water body also sink, applying a downward pressure on the swing folding plate, causing the swing folding plate to swing downward, opening the opening distance at the bottom end of the floating plate, which is more conducive to the sinking of the water body and impurities. The lighter oil is intercepted above the separation plate body. After forming a water-oil separation state, the separation plate body is heavier than oil and lighter than water, and it floats on the water surface, playing a spacing role in the sedimentation separation, facilitating the subsequent discharge of oil from the oil outlet to the oil extraction pipe and the discharge of water from the drain outlet.

[0019] 2. For this sedimentation separation equipment for waste mineral oil, through the added filtration component, the oil enters from the oil inlet end and then is poured into the sieving cavity. Due to the structure of the sieving cavity, the oil can pass through the sieve holes on the sieving cavity and enter the oil outlet end. The small impurities carried in the oil are intercepted by the sieve holes and fall back into the sedimentation separation chamber through the falling opening for re-sedimentation, thereby making the separation effect of the waste mineral oil better.
