Abstract

The utility model discloses a diesel engine starting preheating device for a mine. The diesel engine starting preheating device comprises a diesel engine cooling system, a machine body water jacket port on the lower part of the diesel engine cooling system, an air cylinder cover water jacket port on the upper part of the diesel engine cooling system, and a first thermal cycle pipe, a small boiler and a second thermal cycle pipe which are sequentially connected between the machine body water jacket port and the air cylinder cover water jacket port; the small boiler is positioned below the machine body water jacket port; the upper end of the second thermal cycle pipe is connected with an air exhaust valve; before a diesel engine is started, cooling liquid in the small boiler is heated by using a gasoline torch so as to preheat the diesel engine, and the phenomenon that an oil sump is cracked when the diesel engine is directly braked over fire can be avoided; the damage caused by preheating a storage battery by using an electric heater plug or a flame preheater can be avoided; and the diesel engine starting preheating device has the advantages of safety, efficiency, high thermal efficiency and no damage to the diesel engine and the like.

Description

The diesel engine starting Preheating unit is used in a kind of mine

Technical field

The utility model relates to a kind of mine and uses the diesel engine starting Preheating unit.

Background technique

In the mine produces, generally use diesel engine as power source, diesel engine winter starting difficulty is burnt car with naked light and is started, and is prone to breaking out of fire, burns out circuit, oil sump hardening cracks, machine oil goes bad; Use glow plug fragile storage battery of a specified duration preheat time.

The model utility content

The technical problem that the utility model will solve provides a kind of mine and uses the diesel engine starting Preheating unit, it have safe and effective, not to characteristics such as diesel engine cause damage.

For solving the problems of the technologies described above; The technological scheme that the utility model is taked is: it comprises the body water jacket interface of diesel engine cooling system, diesel engine cooling system bottom and the cylinder head water jacket interface on its top, and it also is included in first heat circulation pipe, arcola, second heat circulation pipe that connects successively between body water jacket interface and the cylinder head water jacket interface in addition; Arcola is positioned at the below of body water jacket interface; The upper end of second heat circulation pipe connects outlet valve.

The utility model further improves and is: first heat circulation pipe and arcola joint are positioned at the below of arcola, and second heat circulation pipe and arcola joint are positioned at the top of arcola; Arcola comprises jacket pipe, is provided with water outlet in the top, and its lower end is provided with water intake, and the inner chamber of jacket pipe is the firing chamber, in the firing chamber, is provided with the heating pipe that a plurality of two ends are communicated with jacket pipe; First heat circulation pipe is connected with the water intake of arcola; Second heat circulation pipe is connected with the water outlet of arcola.

Adopt the beneficial effect that technique scheme produced to be: through diesel engine being carried out preheating, to avoid the direct oil sump cracking that possibly cause before the diesel engine starting with fire baking diesel engine with the cooling liquid in the petrol burner heating arcola; Reach the infringement that storage battery is caused with glow plug or the preheating of flame preheater; Adopt first heat circulation pipe to connect in the below of arcola; Second heat circulation pipe connects in the top of arcola; Such connecting means can form the thermal cycle pattern (being convection current) of a closed loop, accelerates thermal cycle speed, reduces preheat time; Adopt the arcola of said structure can reduce heat-energy losses, thus it have safe and effective, the thermal efficiency is high, not to advantages such as diesel engine cause damage.

Embodiment

Embodiment by shown in Fig. 1-3 can know; It comprises the body water jacket interface 2 of diesel engine cooling system 1, diesel engine cooling system 1 bottom and the cylinder head water jacket interface 3 on its top, and it also is included between body water jacket interface 2 and the cylinder head water jacket interface 3 first heat circulation pipe 4, arcola 6, second heat circulation pipe 5 that connects successively in addition; Arcola 6 is positioned at the below of body water jacket interface 2; The upper end of second heat circulation pipe 5 connects outlet valve 7; First heat circulation pipe 4 and arcola 6 joints are positioned at the below of arcola 6, and second heat circulation pipe 5 and arcola 6 joints are positioned at the top of arcola 6; Arcola 6 comprises jacket pipe 8, is provided with water outlet 12 in the top, and its lower end is provided with water intake 11, and the inner chamber of jacket pipe 8 is firing chamber 9, in firing chamber 9, is provided with the heating pipe 10 that a plurality of two ends are communicated with jacket pipe 8; First heat circulation pipe 4 is connected with the water intake 11 of arcola 6; Second heat circulation pipe 5 is connected with the water outlet 12 of arcola 6.

Method for using:

During use outlet valve is opened the emptying air, and petrol burner is suppressed igniting, the heating pipe that flame is aimed in the firing chamber heats; Cooling liquid in heating pipe and the jacket pipe back density of being heated diminishes and floats, and gets into diesel engine cooling system through water outlet through second heat circulation pipe and carries out preheating, and colder cooling liquid can replenish into through first heat circulation pipe that arcola heats again by the bottom simultaneously; Thereby the formation convection current is carried out preheating with fast speeds to diesel engine, the heating a few minutes after; Touch cylinder head with hand, sensible temperature rises to the temperature that is fit to diesel engine starting, promptly starts diesel engine; After lighting a fire successfully, extinguish blowtorch, heating is accomplished.
