Abstract
Disclosed is a residual liquid cleaning device for oil tanks or oil trucks which may complete the cleaning of the residual liquid at the bottom of the oil tanks or oil trucks. The device is characterized in that the liquid storage buffer tank is placed vertically. The diameter of the buffer tank is 1,500 - 2,500mm with the height of 2,500mm - 4,500mm. A flame retardant respirator is positioned on top of the buffer tank and a blowdown valve available at the bottom. An outlet is arranged at 1,000 - 2,500mm to the buffer tank bottom. The outlet pipeline is used for connection with the oil tank. An inlet is available at 500 - 1,000mm to the buffer tank bottom. An electric displacement pump is connected with the inlet pipeline. The effect of the utility model is that the device is not necessary for manual control. The device has the advantages of high security, low work intensity, good continuous work, and high efficiency. Moreover, the oil, gas, water, and silt sediments are separated and discharged respectively inside the storage liquid buffer tank, thus reducing the water content of the liquid going back to the oil tank and improving the oil quality inside the oil tank.
Description
Technical field
The utility model relates to a kind of device of clearing up tun bottom residual liquid, particularly a kind of device of clearing up oil tank, truck tanker bottom raffinate.
Background technology
Cleaning oil tank, truck tanker bottom raffinate be one heavy, complicated, and dangerous work.Contain a large amount of combustible material oil in the raffinate, in addition particulate contamination such as water that deposits and silt.Combustible material oil need be separated with water, impurity, oil returns oil tank.Oil is volatile, combustible material, has the many places potential safety hazard in conveying and scale removal process.At present, when cleaning oil tank, truck tanker bottom raffinate, adopt positive displacement pump that raffinate oil, water, silt and the air of tank bottom are drawn in the liquid storage expansion tank together.In aspiration procedure, need operating personal constantly with the air exhaustion in the liquid storage expansion tank, and need the liquid level of personal monitoring's liquid storage expansion tank.After the liquid storage expansion tank was full of by liquid, operating personal was restarted another centrifugal pump with the oil in the liquid storage expansion tank, carried the oil return jar; Perhaps stop clearance job, the open and close related valve restarts positive displacement pump the oil in the liquid storage expansion tank is carried the oil return jar.Water in the tank bottom raffinate and silt are cleaned out in so continuous circulation.Because the liquid storage expansion tank oil-water separation of existing residual liquid device is poor, oil, water and the silt etc. of liquid storage expansion tank bottom have been circulated back in the oil tank together in scale removal process, cause in the oil tank moisture too highly, and cleaning cycle prolongs.The discharging of water and silt is untimely in the liquid storage expansion tank of prior art, and phenomenon such as cause tank boil-overs easily, find time exists very big potential safety hazard; The operation technological process complexity of existing installation is easy to generate the maloperation phenomenon in addition; Inefficiency, labor intensity of operating staff is big.
The utility model content
The purpose of this utility model is: a kind of oil tank, truck tanker bottom raffinate cleaning plant are provided, finish tun, especially oil tank, the raffinate cleaning work of truck tanker bottom.It is poor to overcome existing cleaning plant liquid storage expansion tank oil-water separation, and cleaning cycle prolongs; Overcome existing liquid storage expansion tank and cause tank boil-overs easily, find time, exist very big potential safety hazard; Overcome existing installation operation technological process complexity in addition, inefficiency, the deficiency that labor intensity of operating staff is big.
The technical solution adopted in the utility model is: the oil tank after the improvement, truck tanker bottom raffinate cleaning plant structure are: comprise liquid storage expansion tank, positive displacement pump, and pipeline and valve, it is characterized in that: the inner structure of liquid storage expansion tank uniqueness.Liquid storage expansion tank (4) adopts vertical laying.The diameter of liquid storage expansion tank is between the 1000-2500 millimeter, and height is between the 2500-4500 millimeter.At liquid storage expansion tank top fire-retardant respirator is arranged; Foul valve is arranged at liquid storage expansion tank bottom.Apart from 1500-3000 millimeter place, liquid storage expansion tank bottom, outlet is arranged, valve and ball-and-seat are arranged on the discharge pipe, discharge pipe can be connected to oil tank.Apart from 500-1000 millimeter place, liquid storage expansion tank bottom, inlet is arranged, be connected with positive displacement pump on the source line.The positive displacement pump pipeline is connected to the oil tank inner bottom part, starts positive displacement pump, the raffinate of oil tank inner bottom part just can enter the liquid storage expansion tank by positive displacement pump and liquid storage expansion tank inlet.In the liquid storage expansion tank, oil, gas, water and sediment settlement are separated by the inner special isolating construction of liquid storage expansion tank.Gas discharges automatically by the fire-retardant respirator in liquid storage expansion tank top.The density of water and silt is big, is deposited in liquid storage expansion tank bottom, can regularly discharge from liquid storage expansion tank bottom blow valve.The oil that is in liquid storage expansion tank middle part can pass through outlet automatically and flow into oil tank under differential pressure action.Water and silt can regularly be discharged from liquid storage expansion tank bottom, can not enter oil tank.
Move for the ease of oil tank, truck tanker bottom raffinate cleaning plant, oil tank, truck tanker bottom raffinate cleaning plant are whole skid structure.Be that liquid storage expansion tank, electronic positive displacement pump are fixed on the moveable base.
Described positive displacement pump can be used polytype.As blade-type pump, plunger pump or vane pump etc.
Described foul valve can use polytype.As electrical ball valve, electric gate valve, electric butterfly valve, manual ball valve, hand sluice valve, Hand-operated butterfly valve etc.
The beneficial effects of the utility model: adopt the raffinate of the utility model cleaning tank bottom, advantages such as having need not manual control, safety performance height, labour intensity are low, easy to operate, continuous working, work efficiency height.In addition, oil, gas, water and sediment settlement separate in the liquid storage expansion tank, and discharging respectively reduces the aqueous ingredients that returns in the oil tank liquid, improves oil quality in the oil tank.The utility model has bigger improvement at the structure design of tank bottom raffinate cleaning plant, makes it have more practicality, meets the needs of tank bottom raffinate cleaning technology fully, and has produced practical function.It is a new and innovative, progressive, practical new design.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
