Abstract
The utility model discloses a secondary filtering fuel tank structure, which is characterized in that a fuel filter is fixedly arranged in a tank body through a cover plate; the cover plate is connected with the tank body; a base plate of the tank body is of a similar conical surface structure; a similar conical surface is extended to be at an upper part of a storage tank; a ventage is designed on a tip of the similar conical surface of the base plate of the tank body; the storage tank is arranged under the ventage of the base plate of the tank body; a sectional dimension of the storage tank is larger than that of the ventage; a discharge hole is designed in the storage tank; and a fuel suction port is arranged behind the fuel filter. In a fuel tank, water, impurities and fuel can be effectively separated, the cleanness of the fuel entering into a fuel system of an engine is improved, the replacement period of a fuel-water separator and a fuel filter element is prolonged, the maintenance cost is reduced, and the service life of the engine is prolonged. The maintenance is convenient, the fuel filter can be replaced through disassembling the cover plate, and the water and the impurities separated from the fuel can be discharged from the discharge hole.
Description
Technical field
The utility model relate to a kind of for take explosive motor as power engineering mechanical device was used, can significantly improve the cleanliness level of the fuel oil that enters engine fuel oil system, the cascade filtration fuel tank structure that extends the service life of oil water separator, fuel oil filter, driving engine.
Background technology
The home market fuel qualities is uneven, except China Petrochemical Industry, the subordinate's of PetroChina Company Limited. oil company and refinery provides fuel oil for the petrol service station that spreads all over the country, little refinery, the indigenous oil refining factory that also has some provides the fuel oil that does not conform to quality to come into the market to sell by improper channel and uses.In poor quality fuel oil, the content of common moisture and mechanical admixture (insoluble solids particulate) is higher, the existence of moisture is the major cause that the precision pair corrosions such as the high pressure pump plunger that causes driving engine, injector valve damage, mechanical admixture can cause the precision pair wearing and tearing of engine high pressure fuel-feed system, and then causes overall performance reduction, the service life of driving engine to shorten.Therefore, how to improve the problem that the fuel oil cleanliness level has become each producer's research of construction machinery industry.
Modern project machinery generally is provided with the filters such as oil water separator, fuel oil filter after fuel tank, but the filter of any pattern all is subject to the restriction of self certain filter efficiency, therefore, in order to extend the service life of driving engine, further raising seems even more important from the cleanliness level of the fuel oil of fuel tank outflow.The fuel tank that uses on construction machinery and equipment at present is commonly simple flat box typed structure, fuel oil through the lower filter screen of the filtering accuracy that is arranged on the fuel tank entrance after, go out moisture and impurity through standing separation in fuel tank, outlet is external side by side but these moisture and impurity can not collect in the fuel tank bottom, and existence is sucked into the hidden danger of engine fuel oil system, the burden that this has just increased the weight of to be arranged on the filters such as oil water separator after fuel tank, fuel oil filter also makes the risk that driving engine breaks down improve simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of novel fuel tank structure, make fuel oil can effectively separate wherein most moisture and impurity in fuel tank, thus the purpose of the replacement cycle of realization prolongation oil water separator and element of fuel filter, minimizing maintaining cost, reduction engine breakdown risk.
Technical solution of the present utility model is such, a kind of cascade filtration fuel tank structure, comprise fuel oil feeding port, casing, cover plate, fuel oil fitering element, box bottom, leak, holding vessel, escape orifice, oil suction, it is characterized in that the casing top is equipped with cover plate, casing top one side has fuel oil feeding port, fuel oil fitering element is equipped with in the bottom half center, bottom half is equipped with box bottom, there is leak in box bottom bottom centre, there is oil suction the fuel oil fitering element bottom, holding vessel is equipped with in the leak of box bottom below, and there is escape orifice the holding vessel bottom.
Within fuel oil fitering element is fixed in casing by cover plate, cover plate is connected with casing, box bottom is that class cone structure and the class conical surface extend to above holding vessel, the class conical surface sophisticated design of box bottom has leak, holding vessel is arranged under the leak of box bottom, the sectional dimension of holding vessel is designed with escape orifice, after oil suction is arranged in fuel oil fitering element greater than the size of leak on holding vessel.
Holding vessel is contained in the leak periphery, and oil suction passes the outside from holding vessel.
The utility model has the advantages that:
1, after the utility model is implemented, can realize that in fuel tank moisture, impurity effectively separate with fuel oil, improve the cleanliness level of the fuel oil that enters engine fuel oil system, extend the replacement cycle of oil water separator and element of fuel filter, reduce the maintaining cost, extend the service life of driving engine.
2, after the utility model was implemented, maintaining was convenient, and taking cover plate apart is replaceable fuel oil fitering element, can discharge from escape orifice water and the impurity that separates from fuel oil.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is that integral structure of the present utility model is installed the assembling schematic diagram.
In Fig. 1, fuel oil feeding port (1), casing (2), cover plate (3), fuel oil fitering element (4), box bottom (5), leak (6), holding vessel (7), escape orifice (8), oil suction (9), arrow represents the flow direction of fuel oil, and hollow arrow represents the flow direction of moisture and impurity.
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing, fuel oil enters casing (2) inner chamber from fuel oil feeding port (1), through after sufficient standing, in fuel oil, most contamination precipitation is on box bottom (5), simultaneously, because the density of the density ratio fuel oil of water is large, casing (2) bottom is separated and be deposited on to moisture and fuel oil.when equipment is worked, the impurity of precipitation is under the combined action of the vibration of self gravitation and casing (2), the class conical surface along box bottom (5) collects to holding vessel (7) through leak (6), holding vessel (7) is arranged under the leak (6) of box bottom (5), and its sectional dimension is greater than the size of leak (6), the impurity refluence that can prevent from like this coming together in holding vessel (7) is got back to above box bottom (5), open the escape orifice (8) on holding vessel (7), the moisture that separates from fuel oil and impurity are namely discharged outside casing (2), this is that the first order of fuel oil is filtered.Within fuel oil after filtering through the first order is stored in casing (2), when equipment work and need to be to the driving engine fuel time, these fuel oils enter engine fuel oil system from oil suction (9) and supply with oil circuit after fuel oil fitering element (4), fuel oil fitering element (4) but the impurity particle that suspends in the filtering fuel oil, this is that the second stage of fuel oil is filtered.Cover plate (3) is connected with casing (2), its the effect one be fuel oil fitering element (4) is fixed in casing (2) within, the 2nd, as the maintaining mouth of fuel tank, realize changing the operations such as fuel oil fitering element (4), cleaning casing (2) inner chamber.
