Abstract

The utility model relates to a fuel heater of a diesel engine which consists of a water tank in an oil tank, and a water inlet pipe, a water outlet pipe and a spiral pintle. The heater is characterized in that the water inlet pipe of the water tank is connected with the water outlet of an engine circulating and cooling water device; the water outlet pipe of the water tank is connected with the water inlet of the engine circulating and cooling water device; the hot cooling water when an engine works is led to the water tank; the outer wall of the water tank initially heats the fuel in the oil tank; the spiral pintle is arranged in the water tank; the bottom end of the pintle absorbs diesel fuel from the bottom of the oil tank; the top end of the pintle goes through a tank cover and is connected with an engine filter; when the fuel flows past the pintle, the hot water heats the diesel fuel again, so that the temperature of the diesel fuel can be kept a little lower than the temperature of the circulating water of the engine. The fuel heater not only can make sure the diesel engine works normally in cold winter, but also can fully burn the diesel fuel, help to save the operation cost of the engine, reduce the pollution of waste gas to the environment, and is applicable to all water-cooled diesel engines.

Description

The diesel engine fuel heater

[technical field] the utility model relates to a kind of heater, is a kind of diesel engine fuel heater specifically.

[background technique] is present; variously utilize water-cooled diesel engine; for example diesel generating set, automotive Diesel engine and various be the engineering machinery of power with diesel oil; under winter of cold or specific cryogenic conditions; diesel oil freezes in fuel tank or in the transport pipe easily; cause the pipeline road of diesel oil to stop up, cause the flame-out shutdown of internal-combustion engine, bring massive losses for people's productive life.

[summary of the invention] do not install the diesel oil heating equipment for overcoming existing diesel engine, freezes under winter of cold or specific cryogenic conditions easily, cause internal-combustion engine flame-out shut down or start the unsuccessful people's productive life of can giving bring the defective of loss.The utility model provides a kind of waste heat that utilizes the diesel engine recirculated cooling water, to the fuel heater of the diesel cycle in fuel tank heating, makes the diesel engine also can proper functioning under various low temperature environments.

For solving its technical problem, the technical solution adopted in the utility model is: in the fuel tank of present diesel engine, set up a water storage box, this water storage box is fixed on the cover plate at fuel tank top, the water storage box center is provided with a spirality spindle, one end of this spindle stretches out the water storage box base plate, and the spindle mouth stretches to the fuel tank bottom cavity for filler opening; The other end of spindle is an oil outlet, and this oil outlet passes case lid and links to each other with the oil outlet of band valve; One side of the spirality spindle in water storage box is provided with intake pipe, and the spirality spindle opposite side in the water storage box is provided with outlet pipe.During work, the recirculated cooling water of diesel engine is linked to each other with the intake pipe of water storage box by water pipe, the cooling water that is heated that internal-combustion engine is discharged flows into the water storage box bottom, be provided with outlet pipe at the water storage box top, link to each other with the return pipe of recirculating cooling water system by aqueduct, the cooling water of internal-combustion engine is circulated through water storage box; The spirality spindle bottom inlet of setting up in water storage box is located at the fuel tank bottom, suck by the diesel oil of water storage box outer wall heating for the first time in the fuel tank, make diesel oil in water storage box, heat the filter cleaner that afterwards enters internal-combustion engine for the second time, for the diesel engine burning from the outlet on top by the hot water in the water storage box.

The beneficial effects of the utility model are: 1. because the utility model is provided with heating equipment at the fuel tank of diesel engine, make that diesel oil in the fuel tank is unlikely to be freezed under the condition of low temperature, make the diesel engine proper functioning, both made and adjourned serious water snow disaster, also can power with diesel generator, with diesel oil bulldozer cleaning road surface, transport the passenger with the automobile of diesel engine.2. owing to heater described in the utility model, its thermal source is the recirculated cooling water from internal-combustion engine itself, and not needing increases thermal source in addition, belongs to a kind of waste utilization, so heating cost is low, easy to utilize.3. because diesel oil effect of its viscosity and atomizing under different temperature is different, temperature is high more, and viscosity is low more, and atomizing effect is good more, it is safe more to burn, heat release is abundant more, discharges more environmental protection, and oil consumption is low more, therefore both made and used this heater in the season of non-severe cold, under the condition of equal acting, can reduce the operating cost of internal-combustion engine, reduce the pollution of waste gas to environment.

[description of drawings] further specifies the utility model below in conjunction with the drawings and specific embodiments.

Accompanying drawing is a structural representation sectional view of the present utility model.

Among the figure: 1, fuel tank; 2, water storage box; 3, intake pipe; 4, spirality spindle; 5, case lid; 6, outlet pipe.

[embodiment] is with reference to accompanying drawing: in the fuel tank 1 of diesel engine, being provided with a diameter is the cylindrical copper water storage box 2 of 64mm, and this water storage box is suspended on the case lid 5, highly is slightly less than the height of fuel tank; Be provided with a spirality spindle 4 from top to bottom at the center of water storage box, this spindle is that the copper pipe coiling of diameter 8mm forms, the bottom of spindle is a filler opening, it passes in the cavity that the water storage box base plate stretches to fuel tank bottom, so that the diesel oil in the suction fuel tank after the water storage box outer wall heats for the first time, the top of spindle is an oil outlet, and it passes tank cover and is connected with the filter cleaner of internal-combustion engine, in order to the diesel oil after hot water heats for the second time in water storage box to the internal-combustion engine conveying; Side at water storage box is provided with an intake pipe 3, this intake pipe is that the copper pipe of 14mm is made by diameter, the upper end is passed case lid and is connected with the water outlet of engine cycle cooling unit, in order to the hot water of internal-combustion engine output is sent into water storage box, the bottom of water storage box is stretched in the lower end of intake pipe, make hot water enter and fill with water tank from the water storage box bottom, be provided with the copper outlet pipe 6 that a diameter is 14mm at the top of water storage box opposite side, this outlet pipe one end passes case lid and is connected with the water intake of engine cycle chilled water unit, the other end of outflow box stretches to the top of water storage box, be transmitted back to circulating cooler again in order to the recirculated cooling water that will discharge heat, internal-combustion engine is cooled off.
