To achieve these goals, asphalt heater provided by the utility model comprises heating chamber, heat pipe, discharging pump, wherein heat pipe and thermal source are connected to form heat conductive circulation structure, and heating arrangement is made up of heat pipe, and discharging pump and heating chamber connectivity part are discharge port; Described heating arrangement comprises main heating arrangement and discharging heating arrangement, wherein main heating arrangement is laid in heating chamber, discharging heating arrangement is for being close to discharge outlet one independently heat conductive circulation structure, discharging heating arrangement is that heat pipe repeatedly coils or folding to make, and effectively can heat the pitch of 2%-12% volume total amount in discharge outlet.In said apparatus, be provided with main heating arrangement and discharging heating arrangement in heating chamber, wherein main heating arrangement is laid on heating chamber thus can heats heating chamber medium pitch entirety.Discharging heating arrangement is only installed in and is close to discharge port, carries out heating separately with the pitch realized near to discharge port, discharging heating arrangement is set to an independently heat conductive circulation structure simultaneously, thus can regulates and controls separately discharging heating arrangement easily, the independent heating of discharging heating arrangement or discharging heating arrangement and main heating arrangement can be realized and together heat, in addition discharging heating arrangement be set to repeatedly to spiral or foldingly make, thus can increase as far as possible discharging heating arrangement near discharge port with the contact area of pitch, thus make the asphalt heating homogenizing more near discharge port, and discharging heating arrangement effectively heats the pitch of 2%-12% volume total amount near discharge port, generally speaking, the pitch effectively heating 2%-12% volume total amount at discharge port is a kind of energy-conservation effective type of heating, too small at discharge port Effective heating volume, then in real work, discharge outlet asphalt heating speed is slow, melted mass is few, excessive at discharge port Effective heating volume, power consumption increases, and it is excessive to heat volume, pitch easily occurs that heating is uneven, thus there is local ageing of asphalt, when exactly Effective heating volume near discharge port being set to the pitch of 2%-12% volume total amount, namely can be easy rapidly to the Heating temperature of discharging heating arrangement, the parameters such as heat-up time carry out regulable control, guarantee that the asphalt heating near to discharge port is more even, guarantee that realizing pitch the fastest optimum under the prerequisite guaranteeing quality near discharge port carries out heating and melting, and reduce unnecessary energy consumption.In said apparatus, a small amount of pitch be positioned in heating chamber near discharge port can be realized and be heated to upstate rapidly, by this device, the heating and melting of energy-efficient pitch can be realized, and carry out fast energy-saving heating in instant needs during a small amount of pitch.

Further, described heating chamber is Vertical cylinder structure, and wherein mouth material mouth is installed in the outer side wall of this housing structure by bottom position.Discharge port is installed in the outer side wall of housing structure heating chamber by bottom position, thus after the pitch near discharge port melts derivation at first, the temperature adjusting to discharging heating arrangement and main heating arrangement can be passed through, and easier discharge port that the pitch of other position in heating chamber is supplemented to; Meanwhile, discharge port is installed in bottom heating chamber and gravity can be utilized simply to carry out discharging, reduce unnecessary pump pressure energy consumption.

Further, described heat pipe is weldless steel tube, and inside have heat-conducting medium to form heat conductive circulation structure, described heat-conducting medium is thermal oil.Weldless steel tube is the material that a kind of cost performance is higher as heat pipe material, and in asphalt heating field, heat-conducting medium selects thermal oil to be then the generally acknowledged heating medium that effect is fine, cost is not high, thus adopts in the application.

Further, on heat pipe outer wall, interval is enclosed with conducting strip uniformly.The conducting strip that heat pipe outer wall wraps up effectively can increase the surface-area of heat pipe outer wall, and the heat interchanging area of heat pipe and pitch is increased.

Further, described main heating arrangement comprises upper and lower two parts, and main heating arrangement is same heat-circulation structure; Described main heating arrangement top and the bottom are respectively formed with the form dish system of isoplanar spiral of Archimedes by heat pipe.The structure of being spiraled by heat pipe as upper and lower two spiral of Archimedes forms can realize the overall relatively uniform heating of pitch in heating chamber.

Further, to be heat pipe make with the coiling of spring-like form described discharging heating arrangement, described discharging heating arrangement discharge outlet height be heating chamber height overall 1/1 to two/5th between.Heat pipe is spiraled with spring-like form and makes discharging heating arrangement thus the pitch that can realize discharging heating arrangement and discharge outlet has enough large heat interchanging area, can guarantee that the asphalt heating of discharge outlet is even simultaneously.By discharging heating arrangement discharge outlet height be set to heating chamber height overall 1/1 to two/5th between, thus structurally guarantee that discharging heating arrangement is optimized relatively to the asphalt heating scope near discharge port.

By above-mentioned asphalt heater, can realize carrying out energy-efficient heating to the pitch in heating chamber, particularly can be heated to usable temp rapidly for the pitch near discharge port.The heating and melting of energy-efficient pitch can be realized, and carry out fast energy-saving heating in instant needs during a small amount of pitch.
