Description

[0001] Movable apparatus for storing asphalt concrete [0002]

More particularly, the present invention relates to a mobile asbestos storage device capable of moving to a construction site in a state of accommodating an ascon, and capable of keeping the accommodated ascon in a predetermined temperature. When the ascon is discharged through an outlet, So that it is possible to construct a high quality ascon.

Asphalt concrete (hereinafter referred to as "ascon") used in roads is a hydrocarbon mixture, and a solid component called asphaltene is dispersed in an oil component called martin. Or used for waterproofing in packaging or building applications. Alternatively, aggregates of sand, stone, crushed stone, and gravel are mixed with asphalt, which is mainly used for road pavement and airport pavement, and is called ascon.

1, the aggregate fed from an aggregate vessel 10 containing aggregates such as crushed stone, sand, stone powder, and gravel is conveyed through a belt 20 to a dryer 30 And then the aggregate filled in the dryer 30 is heated through the oil burner 40. In this case, Dust and noxious gases generated while being burned by the oil burner 40 are discharged to the outside through the air discharge device 45 and the dust collecting device (not shown).

The aggregates heated in the dryer 30 are moved to the screen 50 by the conveying elevator 80 and classified by size on the screen 50 and then moved down to the mixer 60 . And the asphalt is mixed with various fine fillers and asphalt filled from the filler tower 70 in the blender 60 to produce the ascon. The ascon produced in this manner is filled in the ascon conveying vehicle waiting at the bottom of the blender 60 and then transferred to the site.

A vehicle carrying the thus manufactured asphalt is replaced with a dump truck, and the temperature of the ascon loaded in the transportation vehicle is loaded at a high temperature of about 180 to 200 DEG C and is moved to the construction site. However, the temperature of the ascon is gradually lowered as the time for moving the ascon to the site and the time for working on the site elapses, and the temperature of the ascon, which is used for road pavement or airport pavement, Lt; 0 > C.

Therefore, when using the ascon which is significantly lowered at the road pavement site, there is a problem that it is required to further planarize the ascon which has been lowered on the floor with the mixer.

In addition, it is very disadvantageous to use the ascon which is lowered in temperature when repairing a damaged part of a part of a road which is already packed, or when performing a pavement around the buried manhole. Particularly, in the case of the packing work for reinforcing the perimeter of the manhole, it takes a long time including the moving time because it is buried at a constant interval over several kilometers.

However, as time elapses in the maintenance / reinforcement work of the road for a long time, a part of the ascon which becomes lower in temperature becomes hard. Therefore, it is not possible to use hardened ascon in the field where the working time has elapsed, and when there is a small amount of hardened ascon, there is a problem of environmental pollution which is thrown to one side of the road.

And, since the dump truck was conventionally used to transport the ascon, when the ascon stored in the truck is shipped from the field work, a predetermined amount is taken out by an excavator or the workers shipped a proper amount by using a shovel. This takes a long time and requires a large number of workers.

In order to solve the above-described problems, the present invention can easily transfer the ascon to a construction site while maintaining the ascon at a predetermined temperature, and even when the accommodated ascon is discharged for the construction, the temperature of the discharged ascon is adjusted to a proper temperature And to provide a portable removable asphalt storage device.

According to an aspect of the present invention, there is provided a movable type asphalt storage device comprising: a loading unit having an opening formed on an upper side thereof, an opening and closing unit for opening and closing the opening, A heater unit installed on one side of the stacking unit; A flow path extending from the heater portion and communicating with the accommodating portion; A blower for supplying the heat generated by the heater unit to the accommodating portion through the flow path; An ascon discharging unit for discharging the ascon in the accommodating unit through an outlet formed at a lower side of the loading unit; A first sensor for sensing a temperature of the ascon in the accommodating portion; A second sensor provided at an end of the discharge port to sense a temperature of the ascorbate discharged through the discharge port; And a control unit for comparing the sensed values of the first and second sensors and controlling the heater unit so that the heater unit further generates additional heat for maintaining the temperature of the ascondenser, .

The portable asphalt storage device may further include a third sensor installed outside the loading unit for measuring the atmospheric temperature. The controller may further include a third sensor for detecting the temperature of the atmospheric air before the asphalt is discharged through the outlet, The amount of heat to be supplied to the heater is inversely proportional to the measured value of the third sensor.

The controller may receive the operation value or the expected operation value of the ascender discharger and may control the heater unit such that the amount of heat generated by the heater unit is inversely proportional to the discharge speed of the ascender discharged by the ascender discharger.

According to the movable asphalt storage device of the present invention, by supplying the heated air by the heater section to the loading section capable of storing the ascon, not only the ascon can be easily transferred to the construction site, but also the long time The ascon can be stored in the loading part at a certain high temperature.

Also, even when the ascon is discharged through the discharge port in the receiving portion of the loading portion, the temperature of the ascon in the receiving portion and the temperature of the ascon discharged through the discharge port through the second sensor provided at the end portion of the discharging port The control unit controls the heater unit so that the heater unit generates additional heat for compensating for the difference in the sensed values. Thus, even if the ascorbic acid is exhausted through the discharge port and the heat is taken away from the surroundings, It is possible to maintain an appropriate temperature for this construction.

In addition, even when the temperature of the ascon is discharged through the discharge port, that is, before the discharge of the ascon is started, an additional heat is generated in an inverse proportion to the measured value of the third sensor for measuring the atmospheric temperature It is possible to control the heater unit so that the ascon of the appropriate temperature for the construction can be supplied immediately from the start of discharge regardless of the temperature change of the site.

Therefore, it is always convenient to use Ascon, which has a suitable temperature for construction, when the distance of transfer of the ascon to the construction site is long, when the temperature of the site is very low or high according to the season change, And can be easily supplied to the construction site.

The flow paths 118a and 118b are formed between the inlet 119b and the outlet 119a so that the inlet 119b of the flow paths 118a and 118b communicates with the heater 130, (119a) communicates with the interior of the loading unit (100). That is, the flow paths 118a and 118b are formed in the bottom surface 116 and the side surface 114 of the loading unit 100, respectively.

Meanwhile, a heater unit 130 is provided on one side of the loading unit 100. The heater unit 130 converts electric energy into heat energy and is well known in the industrial field and in many devices requiring heat energy, so that a detailed description thereof will be omitted.

In addition, a first sensor 160 for sensing the temperature of the heat is installed in the interior of the loading unit 100, that is, the receiving unit 110. The first sensor 160 may be connected to the controller 180 to control the operation of the heater 130 so that the temperature of the interior of the loading unit 100 may be maintained constant.

The switch (140) is installed in the opening (112). That is, it is coupled to both sides of the upper end of the loading unit 100 and is automatically opened and closed by a hydraulic cylinder (not shown). The switch 140 is opened and closed while being rotated in both directions toward the central portion of the loading unit 100. The switch 140 is preferably made of glass fiber insulation. This is because heat loss can be most effectively suppressed.

The portable asbestos storage device according to the first embodiment of the present invention includes an ascon discharging device 190 inside the loading unit 100. The aspirator discharging device 190 includes a driving unit 191 and a rotating shaft 192, and a screw 193 and an outlet 194.

A driving unit 191 is provided at a position adjacent to the heater unit 130 on the outside of the front of the loading unit 100. Most preferably, the driving unit 191 is constituted by a driving motor driven by electric energy. However, it is also possible for a worker to manually operate by applying a rotational force.

The driving shaft 191 is coupled to a rotating shaft 192. Both ends of the rotary shaft 192 are inserted into the front and rear of the loading unit 100 so that the rotary shaft 192 can be rotated. A spiral screw 193 is coupled to the outer circumferential portion of the rotary shaft 192 along the longitudinal direction thereof. The rotary shaft 192 is located inside the loading unit 100, more preferably at the center of the bottom surface 116 of the loading unit 100. The bottom surface 116 is formed to be inclined at both sides of the screw 193.

An outlet 194 is provided behind the loading unit 100 where the screw 193 is located. The discharge port 194 protrudes outwardly of the loading unit 100 and has an opening.

Meanwhile, the second sensor 200 is provided at the end of the discharge port 194. The second sensor 200 senses the temperature of the ascender A discharged through the discharge port 194 and transmits the sensed temperature to the controller 180. The controller 180 controls the heater 130 to generate additional heat when the sensed value of the sensed value is lower than a preset proper temperature according to the sensed value of the second sensor 200, So that the temperature of the ascon (A) is maintained at an appropriate temperature or higher.

The display unit 170 displays the sensed value of the first sensor 160 which is the temperature of the ascender A of the loading unit 100 and the sensed value of the second sensor 200 which is the temperature of the ascender A discharged through the outlet 194. [ ) So that the operator can confirm the detection value. The display unit 170 may be further provided to display the amount of heat generated by the heater unit 130 or the power applied to the heater unit 130.

Hereinafter, the operation of the mobile asbestos storage device according to the first embodiment of the present invention will be described.

First, the ascon A produced by the ascon production apparatus is loaded on the loading section 100 provided in the transportation vehicle. When the loading unit 100 is filled with the ascon, the opening and closing unit 140 is covered, and the asphalt floor is easily transferred to a construction site where reinforcement and maintenance work is performed.

At this time, the controller 180 receives the sensing value of the first sensor 160 and controls the heater 130 to maintain the temperature of the ascon in the loading unit 100 higher than the predetermined temperature by a preset value .

For example, assuming that the proper temperature of the ascon to be suitable for construction is 150 占 폚 and the predetermined value is 2 占 폚, the controller 180 controls the temperature of the ascon in the loading unit 100 to be maintained at 152 占 폚 So as to control the heater unit 130 as much as possible.

The preset value is set such that when the asphalt A contained in the loading unit 100 is discharged to the discharge port 194 by the ascondon discharging device 190, In order to keep the temperature of the ascons A accommodated in the stacking unit 100 higher.

Thereafter, the ascon A is discharged to the installation position through the ascon discharging device 190. That is, the driving unit 191 is operated to rotate the rotary shaft 192 integrally coupled with the screw 193, and the ascon A accommodated in the loading unit is rotated constantly through the outlet 194 by the rotational force .

At this time, the controller 180 receives the sensed value of the second sensor 200, which is the temperature of the ascender A discharged through the discharge port 194, and calculates a difference value from the sensed value of the first sensor 160 . Then, the heater unit 130 is controlled so that the temperature of the ascorbic A in the loading unit 100 is maintained at a temperature higher than the proper temperature by the difference value.

That is, in the example described above, if the detection value of the second sensor 200 is 148 ° C, the difference value from the detection value of the first sensor 160 is 4 ° C, And controls the heater unit 130 to generate additional heat so that the temperature of the ascon (A) inside the loading unit 100 is maintained at 154 ° C, which is 4 ° C higher.

By the control of the controller 180, the temperature of the ascon A discharged through the discharge port 194 continuously maintains an appropriate temperature, thereby improving the construction quality.

Hereinafter, with reference to FIG. 4, the configuration, operation effect, and use state of the portable asphalt storage device according to the second embodiment of the present invention will be described in detail. The movable asphalt storage device according to the second embodiment of the present invention includes the movable asphalt storage device according to the first embodiment of the present invention except for the third sensor 300, the control part 180 'and the display part 170' Its composition is similar. Accordingly, the third sensor 300, the controller 180 ', and the display unit 170' of the mobile asbestos storage device according to the second embodiment of the present invention will be mainly described. Reference is made to the description of the embodiment.

The third sensor 300 is installed outside the loading unit 100 to measure the atmospheric temperature at the construction site. The control unit 180 'receives the measurement value of the third sensor 300 before the discharge of the ascender A through the discharge port 194, so that the amount of heat additionally generated in the heater unit 130, And controls the heater unit 130 to be in inverse proportion to the measured value of the sensor 300. [

More specifically, as described above, the controller 180 'controls the heater unit 130 so that the sensed value of the first sensor 160 may be maintained higher than the temperature of the Ascon A, In the second embodiment of the present invention, the measurement value of the third sensor 300 is received and compared with the reference ambient temperature, and the measured value of the third sensor 300 Correct the preset value to be in inverse proportion.

For example, it is assumed that the temperature of the ascon (A) suitable for the construction is 150 ° C and the preset value is 2 ° C, and the ambient temperature serving as the reference of the predetermined value is 20 ° C, The measured value of the third sensor 300 is 15 DEG C lower than the reference ambient temperature, so that the predetermined value is largely corrected to be in inverse proportion to the smaller value. For example, the preset value can be largely corrected from 2 캜 to 4 캜.

The magnitude of the value to be compensated in this way can be suitably determined according to the mechanical characteristics such as the structure of the movable asphalt storage device and the position of the discharge port 194.

In this case, the controller 180 'further causes the heater unit 130 to generate additional heat so that the temperature of the Ascon A in the loading unit 100 is maintained at 154 ° C, which is higher than the proper temperature, The heater unit 130 is controlled.

The reason for determining the temperature of the ascender A accommodated in the loading unit 100 by reflecting the temperature of the air, which is the measured value of the third sensor 300, is that the lower the atmospheric temperature is, The temperature of the ascender A contained in the stacking unit 100 is maintained higher as the temperature of the atmosphere is lower in order to reflect the temperature of the ascender A of the outlet 194, So that when the discharge of the ascender A is started through the discharge port 194, the temperature can be discharged at a temperature suitable for the construction.

When the discharge of the ascender A through the discharge port 194 is started, the controller 180 'controls the heater unit 130' according to the sensed value of the second sensor 200, which is the actual temperature of the discharged ascender A ' ) Is controlled as described in the first embodiment.

The display unit 170 'may be configured to display the temperature of the current standby state, which is the measured value of the third sensor 300, and the correction values of the predetermined values to the operator together with the information described in the first embodiment have.

As described above, by using the movable ascon storage device according to the present invention, it is possible to transfer the ascon to the construction site while maintaining the ascon at a predetermined temperature, and to remove the ascon (A) The temperature of the ascender A of the stacking unit 100 is maintained at a predetermined temperature higher than the proper temperature in consideration of the increase or decrease in the amount of heat taken by the temperature of the atmosphere in consideration of the amount of heat, It is possible to keep the temperature of the cone (A) at the appropriate temperature.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. will be.
