Abstract
The utility model discloses a continuous type reversed compulsory mixing drying cylinder body which is provided with a rotary cylinder body, wherein the inner wall of the cylinder body is provided with a secret palace type fire wall; an inner cavity of the cylinder body is divided into two spaces including a heating and drying chamber and an asphalt mixing chamber by the fire wall; the fire wall is used for stopping the high-temperature and high-speed airflow in the heating and drying chamber to enter the asphalt mixing chamber; the fire wall comprises a plurality of multi-head helical blades arranged on the inner wall of an outer cylinder in a surrounding way; an air induction hole formed by a conical barrel is arranged in the center of the fire wall; the lower parts of the helical blades correspond to the conical barrel arranged at an inlet of an air induction duct; the air induction hole is connected with the air induction duct, extends outside the cylinder body and is connected with an induced draft fan; the inner wall of the asphalt mixing chamber is provided with a reverse-flow type mixing blade.The continuous type reversed compulsory mixing drying cylinder body is simple in structure and high in heat transfer efficiency, and is capable of eliminating the aging of the asphalt and guaranteeing the mineral powder adding accuracy; the qualified asphalt mixture which meets the standard requirements can be produced by the continuous type reversed compulsory mixing drying cylinder body.
Description
Technical field
The utility model belongs to road construction work technical field, is specifically related to the reverse action of forced stirring Drying of the continous way cylindrical shell that a kind of asphalt mixing apparatus is used.
Background technology
Continuous type drying drum is as the vitals of asphalt mixing apparatus, it has changed the reverse-flow feeding manner of traditional Drying, and make cold burden enter Drying (downflow type) from same one end that burner is installed, and Drying is extended and be divided into two parts: first half is baking zone, latter half of for mixing and stirring district, allow dry and mix and stir operation complete in a cylinder, thereby cancelled, hot material promotes and the equipment of screening, and the process of drying and mixing and stirring is carried out continuously.There are the following problems for this Drying: the lightweight oil content in (1) pitch, producing blue smoke with the contacting of thermal-flame and hot gas, causes smoke-discharging pollution, meanwhile, also causes the aging of pitch; (2) problem such as also may cause obstruction because dust, oil smoke enter sack cleaner, burn out, thereby must not no longer add cleaner, this has reduced the superiority of drum-type stirring equipment aspect mobility to a certain extent, the breeze adding is siphoned away by the air inducing of high current in passage, has also affected the accuracy of metering.
Twin-roll asphalt mixing plant, its Drying has urceolus and inner core, and inner core is the complete reverse-flow Drying the same with batch (-type), just at its formatted window of afterbody, can make the people's urceolus that gathers materials to fall of super heating.The Drying structure of this structure is more complicated, and in the time aggregate being strengthened to heating, the heat requirement of cylinder is quite high, and the temperature of barrel also rises very highly, has increased the radiation loss of barrel, and has also reduced the life-span of barrel heat proof material.
Utility model content
For solving above-mentioned existing problem, the purpose of this utility model is that design is a kind of simple in structure, and heat transference efficiency is high, eliminates the aging of pitch, ensures the reverse action of forced stirring Drying of the continous way cylindrical shell of the precision of adding breeze.
For achieving the above object, the technical solution adopted in the utility model is: the reverse action of forced stirring Drying of this continous way cylindrical shell, there is rotatable cylindrical shell, it is characterized in that: described cylinder inboard wall is provided with close palace type fire division wall, described fire division wall makes cylinder lumen form heating, drying chamber and Liang Ge space, asphalt mixing chamber, for stopping that the indoor high-temperature high-speed airflow of heating, drying enters asphalt mixing chamber, described fire division wall is made up of around the multi-head spiral blade being arranged on outer tube inner wall multiple, be positioned at fire division wall center and be provided with the air-vent being formed by conical shell, the conical shell of the bottom of described helical blade and the entrance of induced duct adapts, air-vent connects induced duct, and extend to that cylindrical shell is outer to be connected with air-introduced machine, the inwall of described asphalt mixing chamber is provided with reverse-flow stirring vane.
Described fire division wall leans on rear in the middle of being positioned at cylindrical shell, and described heating, drying chamber and asphalt mixing chamber are coaxial.
Adopt the beneficial effect of technique scheme: the reverse action of forced stirring Drying of this continous way cylindrical shell is provided with close palace type fire division wall and coupled air inducing body in centre by rear, by fire division wall, cylindrical shell is separated into former and later two individual cavity, it is characterized in that: two individual cavity before and after by the close palace type fire division wall of rear, whole cylindrical shell being divided in the middle of cylindrical shell.Anterior cavity is the building stones thermal treatment zone, enters in the cavity of rear portion in rotation process at cylindrical shell by close palace type fire division wall, and rear portion cavity is stirring area, thereby flame and high-temperature gas are separated and make stirring area not become high temperature by close palace type fire division wall; The air inducing body being connected with close palace type fire division wall is middle by high-temperature gas carrying-off from it by gas, in stirring area, do not become high velocity air like this, can not cause ageing of asphalt, in stirring area, not becoming the breeze that high velocity air adds just can not be sucked away, ensure the accuracy that breeze adds, thereby produced qualified bituminous mixture.
Brief description of the drawings
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The reverse action of forced stirring Drying of this continous way cylindrical shell as shown in Figure 1, there is rotatable cylindrical shell 1, in the middle of described cylinder inboard wall, be provided with close palace type fire division wall 3 by rear, described fire division wall makes cylinder lumen form heating, drying chamber 2 and space, 4 two of asphalt mixing chambers, this heating, drying chamber and asphalt mixing chamber are coaxial, for stopping that the indoor high-temperature high-speed airflow of heating, drying enters asphalt mixing chamber, described fire division wall 3 is made up of around the multi-head spiral blade being arranged on outer tube inner wall multiple, be positioned at fire division wall center and be provided with the air-vent 6 being formed by conical shell, the conical shell of the bottom of described helical blade and the entrance of induced duct adapts, air-vent connects induced duct 5, and extend to that cylindrical shell is outer to be connected with air-introduced machine, the inwall of described asphalt mixing chamber is provided with reverse-flow stirring vane.
