Abstract

The utility model relates to a device used for conveying and melting asphalt or similar materials, particularly a device which uses heat transfer oil to melt the asphalt. The utility model comprises a bracket, a heater and an asphalt storage tank, wherein, the inner part of a tank body of the asphalt storage tank is provided with a heat radiating pipe which is filled with the heat transfer oil. The utility model has the advantages of simple structure, strong maneuverability, convenient operation, no pollution on environment, and convenient operation.

Description

Moving asphalt heating device

The utility model relates to the device of a kind of conveying and molten asphalt or analogous material, especially uses the equipment of thermal oil molten asphalt.

Existing mobile bitumen heating unit generally all adopts the mode of indirect heating, a kind of " not polluting the mobile bitumen process furnace " disclosed as Chinese patent CN2134396Y, this device is in closed stove heating kettle to be set, use firewood or electricity to heat from pot bottom, the shortcoming of this type of heating is that naked light directly contacts with tar kettle, be easy to cause danger, by job specifications is forbidden.Next is to produce a large amount of poison gas in the heat-processed, contaminate environment, and therefore, this process furnace also is provided with a cover smoke comprehensive purifying device, and this had both increased the complexity of equipment, and working efficiency is not high yet.Chinese patent CN2131859Y discloses a kind of " portable bottled asphalt fusing heating installation ", this equipment is that pitch is loaded and transported with keg, after arriving the point of destination, keg is heated, pitch is poured in the main box of bottom and then pumped for using, the shortcoming of this equipment is (1) complex structure, and entire equipment has comprised pitch bucket and stationary installation thereof, and burner, windlass, pitch are stored many cover systems such as casing.(2) fire orifice is directly aimed at pitch bucket outlet and is heated, and naked light is contacted with pitch, causes the accident.(3) use inconvenience,, go out in barrel process to expend the plenty of time in the pitch barrelling.

The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, easy to use, without the naked light pitch of directly heating, the packaged type asphalt heater that maneuvering ability is good.

The utility model comprises support, and pitch hold tank and well heater are provided with scatterer in the pitch hold tank.This scatterer heating end places near the well heater.

Scatterer in the above-mentioned pitch hold tank can be selected the radiating pipe of inner falling heat-transfer oil or other similar heat-transfer mediums.Extension at pitch hold tank outside radiating pipe is connected to the thermal oil recycle pump, and the tank top also is provided with the high level tank that is connected with radiating pipe.

The utility model well heater can be selected coal stove well heater, oil heater or other types heating unit, and the exhaust gases passes of well heater passes through from pitch hold tank inside, can make full use of heat energy, quickens asphalt melting.

The utility model has the advantages that simple in structurely, mobility strong, whole device add walks mechanism capablely, can move at any time, also can not adorn fixedly travel mechanism, and transport with car.Its major advantage is that well heater and pitch hold tank are fixed as one, and from the inner heating of pitch hold tank, has made full use of heat energy, and rate of heating is fast, and is easy to use, avoided naked light to add heated bitumen and caused smoke pollution and danger.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a packaged type asphalt heater principle schematic.

Fig. 2 is the packaged type asphalt heater structural representation that adopts coal stove well heater, thermal oil radiating pipe.

Fig. 3 is coal stove heater structure figure.

With reference to Fig. 1, the utility model packaged type asphalt heater is by support 1, well heater 2, and pitch hold tank 3 is formed.Scatterer 4 places in the pitch hold tank, and the heating end 5 of this scatterer places near the well heater 2, and this asphalt heater can also can be put into this device on the motor vehicle in the bottom of support 1 dress travel mechanism, walks with garage.During use, decide the place with injecting pitch in the pitch hold tank, transport to give, start well heater 2, scatterer heating end 5 temperature raise, and then have improved the temperature of entire radiator, cause jar interior pitch to melt gradually, can take out use.

Fig. 2 is an exemplary embodiments of the utility model packaged type asphalt heater, in the present embodiment, scatterer 4 is the radiating pipe of inner falling heat-transfer oil, this radiating pipe is at the external thermal oil recycle pump 10 of extension serial connection of asphalt tank, and the top of asphalt tank also has a high level tank 8 to communicate with radiating pipe.

Well heater in the present embodiment has been selected the coal stove well heater for use, and the heating end 5 of scatterer 4 places in the flue 7 of burner hearth one side, and this flue 7 passes the pitch tank interior, and smoke outlet places tank deck, and an induced draft fan 9 forced fume exhausts are set in addition.

Fig. 3 is the coal well heater example structure figure of the utility model packaged type asphalt heater, and this coal stove well heater is made up of two burner hearths that are separated from each other (11,12), the two common flue 7, and scatterer heating end 5 places in the flue 7.
