Accompanying drawing explanation
Fig. 1 is the present invention for the vacuum of tank cleaning, heating, filtration trinity tank arrangement structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used to limit the scope of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of vacuum for tank cleaning, heating, filtration trinity tank arrangement, comprising: tank body 1, steam-water separation tank 2, water ring vacuum pump 3,
Described steam-water separation tank provides operating fluid for water ring vacuum pump,
By water ring vacuum pump discharge pipe, tank interior is found time, makes tank interior form negative pressure, the crude oil in the petrol storage tank be connected with tank body is drawn in tank body,
Described tank interior is provided with heating coil, and described heating coil heats the crude oil in tank body,
Also have filtering net 5 in described tank body, the crude oil entering tank interior is filtered;
Described tank body 1 is connected with centrifugal pump, and the liquid after heating and filtering in tank body carries out aspirating and being transferred to appointed place by described centrifugal pump.
When the special thickness of crude oil liquid, by the heating coil of inside, liquid is heated, make it have certain flowing power, even if external environment condition is severe, temperature is lower, does not also affect the heating of liquid when fluid transfer temperature drop is large, also without the need to additional heating arrangement before and after vacuum reservoir again.In addition, when crude oil liquid contain impurity more time, in order to filter inner impurity, add filtering function, liquid is by after filtering net, and contaminant filter affect pump transmission falls, and greatly reduces the loss of pump, while can improve the quality of liquid.
Preferably, described tank body is provided with the access opening for overhauling, and is convenient to follow-up workman maintenance.
