Abstract
The utility model relates to a diesel oil filtering device, particularly a magnetic precipitation filter for diesel oil which is composed of a bottom seat, a precipitation cup, a bracket, a copper filter screen and a permanent magnet. An oil inlet (2), an oil outlet (19) and a gas exhaust vent (22) are arranged on the bottom seat (2), and the permanent magnet (8) and the bracket (10) provided with the copper filter screen (16) are connected below the bottom seat by a screw rod (14) and screw nuts (13); screw nails (4) are used for connecting the precipitation cup (7), and an external cavity and an inner cavity of the precipitation cup (7) are formed. Fuel oil in the oil tank enters the external cavity from the oil inlet (3), impurities are adsorbed and precipitated by the permanent magnet, and the fuel oil is filtered by the filter screen (16), then the fuel oil purified enters an oil transfer pump from the inner cavity through the oil outlet (19). The diesel oil filtering device is suitable for filtering the fuel oil before the oil transfer pump.
Description
The utility model relates to filtering device for diesel, particularly diesel oil magnetization deposition filter.
The oil supply system of diesel engine is in the prior art: diesel oil by fuel tank through oil transfer pump chimney filter, oil transfer pump, diesel-oil filter, Injection Pump, oil nozzle, enter cylinder or refueling water separator between fuel tank and oil transfer pump chimney filter, such oil supply system can cause the obstruction of oil transfer pump chimney filter, increase the purification load of diesel-oil filter, filter cleaner is easily stopped up and damage, fine impurity easily sees through the papery filter core and enters Injection Pump, quickens the wearing and tearing of injection pump plunger, reduces engine power.
" a kind of diesel fuel filter " of application number 94248308.1, though also adopt magnet that fuel oil is purified, complex structure, the manufacture cost height can only be installed in oil transfer pump between the Injection Pump, can not solve the purifying problem before fuel oil enters oil transfer pump.
The purpose of this utility model is: a kind of diesel oil magnetization deposition filter is provided, it is by base, permanent magnet, carriage, copper filter screen and sediment bowl are formed, be installed between fuel tank and the oil transfer pump, diesel oil enters the sediment bowl exocoel by filler opening, through permanent magnet ferrous contaminants is adsorbed, the water that can not be adsorbed and other impurity are descending with oil, at the bottom of heavier impurity and water are deposited in glass, descending fuel oil is filtered once more by the copper filter screen on the carriage, enter the sediment bowl inner chamber, enter oil transfer pump by oil outlet, finish the preliminary purification of fuel oil, thereby alleviate the wearing and tearing of oil transfer pump and the working load of filter cleaner, improve diesel oil and advanced the preceding turbidity test of pump, prolong oil transfer pump, the working life of Injection Pump and oil nozzle, improved engine power, reduced maintenance expenses.
Formation of the present utility model: by base, sediment bowl, carriage, copper filter screen, screw rod, permanent magnet is formed, mounting plate and the ear shape boss upwards holded up are arranged on the circumference of base (2), mounting hole (1) is arranged on mounting plate, attachment hole (21) is arranged on ear shape boss, the oil inlet hole (3) and the oil outlet (19) that are communicated with the bottom are arranged on circumference, there is the exhaust port (22) that is communicated with up and down the centre, exhaust bolt (20) is installed on exhaust port, there is tapped hole (23) below, screw rod (14) and nut (13) stationary cylinder shape permanent magnet (8) and carriage (10), copper filter screen (16) is installed on the window of carriage, below base by the fixing sediment bowl (7) of screw (4).Base (2) is a disc, the middle part raises up, be downwards cylindrical, there is the ring-shaped step of installation permanent magnet (8) end, the circular groove of oriented under shed (24) on cylinder, three ear shape boss are arranged on the circumference, an attachment hole (21) is arranged on each boss, two mounting holes (1) are arranged on the mounting plate.Carriage (10) is tubaeform, and flange is arranged on horn mouth, and uniform four windows on the conical horn body are installed copper filter screen (16) on window, in the bottom of circular cone circular hole is arranged.Sediment bowl (7) is made up of cylindrical body and cone, and the centre is a cavity, and conical bottom has the tapped hole that blowdown bolt (15) is installed, and the cylindrical body oral area has three overhanging ear shape boss, and tapped hole is arranged on the boss.
Compared with the prior art, the utility model is simple in structure, and the most impurity in the disposable removing fuel oil of energy make oil circuit be difficult for stopping up, and easy to install, cost is low.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is understructure figure;
Accompanying drawing 3 is A-A sectional views of accompanying drawing 2;
Accompanying drawing 4 is rear views of accompanying drawing 2;
Accompanying drawing 5 is carriage and copper filter structure figure.
Embodiment of the present utility model: as shown in Figure 1, screw rod (14) is installed in the below tapped hole (23) of base (2), suit seal ring (6) on screw rod, permanent magnet (8), seal ring (9), carriage (10) and seal ring (11), piece together tightly on base (2) with nut (13), form the sediment bowl inner chamber of sealing, copper filter screen (16) is installed on four windows of carriage (10), below base, connect sediment bowl (7) with screw (4), seal ring (5) is arranged on base and sediment bowl interface, in the sediment bowl bottom blowdown bolt (15) is arranged, go up at the exhaust port (22) of base exhaust bolt (20) is installed.Diesel oil in the fuel tank enters the sediment bowl exocoel by oil inlet hole (3), descending through permanent magnet (8) upper-end surface and outer ring surface, iron tramp is adsorbed on the magnet, the water that is not adsorbed and other impurity continue descending with oil, at the bottom of heavier impurity and water are deposited in glass, the copper filter screen (16) of descending fuel oil on carriage (10) enters the sediment bowl inner chamber, what can not precipitate is kept off at the sediment bowl exocoel by copper filter screen (16) than light impurity, finish the fuel oil preliminary purification, the fuel oil after the purification enters oil transfer pump by oil outlet (19).
The water of precipitation and impurity can be opened blowdown bolt (15) and discharge, and are adsorbed in impurity on the magnet and can open sediment bowl (7) and remove.
