The present invention relates to a heat melting apparatus for heating and melting asphalt in a solid state widely used as a waterproofing material. More specifically, it is possible to melt at a high temperature so that the asphalt physical properties do not change, and the solid asphalt is quickly heated and melted to shorten the working time to improve the work efficiency, and deformation of parts occurs due to high temperature heat. Even if the gap does not occur even by this, it is to provide a heating and melting apparatus to obtain a sure leak-proof structure to facilitate the smooth operation.

In general, in the construction of concrete structures, bridge decks, etc., it is essentially waterproof to prevent cracking and aging due to steel corrosion.

In this waterproof construction, coating type waterproofing material or sheet type waterproofing material is widely used, and among the waterproofing materials, the asphalt which has excellent waterproofing property and adhesive property together with other waterproofing materials is applied to the concrete base surface in liquid phase or laid in sheet state. The method is widely used.

In this case, when the liquid asphalt is used as the waterproofing material, the waterproofing material penetrates to the minute cracks of the base surface to obtain an excellent waterproofing effect. This is inconvenient to do.

In addition, when melting the asphalt of the solid state by direct heating method, the physical properties of the asphalt is not changed to meet the characteristics required as a waterproof material, due to the harmful smoke and odor generated by the direct heating method of the worker The work environment is very bad.

Particularly, in the case of rubber asphalt, there is a problem in that it cannot perform a function as a waterproofing material because the physical property is hardened and is easily changed by heat.

Accordingly, the asphalt was dissolved in the solvent to make it liquid at room temperature. However, the hardening time of the asphalt takes a lot of construction time, and the solvent is also harmful to the human body, causing problems in the working environment. There is also a problem that causes an increase in the material cost.

On the other hand, in order to solve the above problems there is disclosed a patent registration No. 438098 (name: asphalt indirect heating dissolving device), which will be described in detail with reference to the accompanying drawings as follows.

First, Figure 1 is a cross-sectional view showing the configuration of a conventional heating dissolving device, as shown in the conventional dissolving device 1, the combustion chamber (3) in the inner center of the housing (2) made of a double wall with a heat insulating material for high thermal efficiency And a coil-shaped first conduit portion 11 is disposed outside the heat transfer medium heated by fuel combustion of the burner 4 installed to communicate with the combustion chamber 3 on one side of the housing 2. Receiving to be movable, the receiving portion 6 for accommodating the asphalt is formed on the outside of the combustion chamber (3), and the upper and lower second pipe passages of the spiral shape on the upper and lower portions of the receiving portion (6) (12) (13) is arranged to movably receive the heat transfer medium heated in the combustion chamber (3).

The outlet side of the first conduit 11 is connected to the inlet side of the lower second conduit 12 provided in the accommodating part 6 for accommodating asphalt, and the first conduit 11 installed in the combustion chamber 3. The heat transfer medium in) is heated and then moved to the lower second conduit portion 12 to melt the solid asphalt contained in the accommodating portion 6 by indirect heating.

In addition, the heat transfer medium passes through the lower second conduit portion 12 and is cooled by heating the asphalt in the solid state, and the cooled heat transfer medium flows into the jacket 5 formed outside the high temperature combustion chamber 3 and the combustion chamber ( 3) It is reheated by continuous transmission through the wall, and flows into the upper second pipe part 13 installed in the upper space of the accommodating part 6 to melt the asphalt contained therein.

At this time, the outlet side of the upper second pipe part 13 is connected to the circulation pump 10, the inlet side of the first pipe part 11 is also connected to the circulation pump 10, the heat transfer by the circulation pump 10 The medium is supplied to the lower second conduit part 12 through the first conduit part 11, and then to the upper second conduit part 13 through the jacket 5, and then to the circulation pump 10. The supply process is circulated and heated in the combustion chamber 3 and the jacket 5 to melt the asphalt in the accommodating part 6 using the heated temperature.

In addition, the upper and lower sides of the accommodating part 6 are coupled to the screw 8 which is rotated by the drive motor 7, respectively, so that the asphalt in the molten state is the upper and lower second conduit parts 12 and 13 and If it is in contact with the jacket 5 for a long time, burning may occur due to high temperature heat. Therefore, molten asphalt is circulated by the rotational force of the screw 8, and the asphalt in the receiving part 6 is maintained at a uniform temperature throughout. To be possible.

On the other hand, the asphalt in the receiving portion 6 is indirectly heated to 150 ° C to 210 ° C to be melted without changing physical properties.

In the conventional dissolving apparatus 1, the shape of the combustion chamber 3 and the jacket 5 is deformed as the asphalt is melted at a high temperature, so that the molten asphalt leaks into a gap generated during deformation. .

That is, when the burner 4 burns fuel and heats the combustion chamber 3, the asphalt in the accommodating part 6 should be heated to 150 ° C. to 210 ° C., and thus a higher temperature should be formed. 3) and the components constituting the jacket 5 is deformed by heat.

When deformation occurs in the parts constituting the combustion chamber 3 and the jacket 5 as described above, deformation occurs in a portion closely coupled with the housing 2 and a gap is generated, and asphalt is leaked into the gap.

In addition, when the deformation of the combustion chamber 3 occurs, the flame generated by the burner 4 intensively heats one side of the combustion chamber 3, whereby a part of the first conduit 11 is concentrated. Deformation occurs by heating, and a large problem arises that the heat transfer medium expands instantaneously due to intensive heating and damages the first conduit portion 11 so that the dissolution device 1 cannot be operated.

In addition, the shape of the upper and lower second conduits 12 and 13 may also be deformed by high temperature heat, and may be combined with the housing 2 of the driving motor 7 for rotating the screw 8. Components that seal the sealant do not withstand high heat and deformation occurs, causing the asphalt to leak into that portion.

In addition, the screw 8 is also bent due to high temperature heat and deformation occurs, and the upper and lower second pipe parts 12 and 13 are also deformed due to high temperature heat, so that the screw is driven by the drive motor 7. (8) rotates smoothly and the asphalt must be circulated, but the deformed screw (8) rotates and comes into contact with the upper and lower second conduit portions (12) (13), resulting in loud noises, In addition, a large problem occurs that the upper and lower second pipe parts 12 and 13 are damaged by the screw 8.

On the other hand, since the path through which the heat transfer medium circulates is very complicated and long, it takes a lot of time to melt the asphalt in the solid state, not only can not proceed fast work, but also increases the working period accordingly.

The present invention was devised to solve the above problems, and melted at a high temperature so as not to change the physical properties of the asphalt, and at the same time, even if the deformation of the component caused by the high temperature heat does not cause a gap caused by this, a sure leak prevention It is an object of the present invention to provide a heating and melting apparatus for obtaining a structure and allowing a smooth operation to proceed.

In addition, there is also an object to improve the work efficiency by shortening the working time by enabling the rapid heating and melting of the asphalt in the solid state.

In addition, there is also an object to be able to simply put the asphalt in the solid state into the heat melting apparatus.

A door 102 is provided at the upper portion of the 101 to open or close the upper portion of the accommodating portion 103 to inject the solid asphalt 190 into the accommodating portion 103.

In addition, a heat transfer medium is filled in the heating chamber 110 formed around the front, rear and bottom surfaces of the accommodating part 103, and a plurality of heaters 111 are installed in the heating chamber 110 to heat the heating chamber 110. The heat transfer medium filled in is heated.

In this case, a plurality of auxiliary heating chambers 120 connected to the front and rear heating chambers 110 and penetrating the receiving portions 103 are formed in the accommodating part 103, and the solid accommodated in the accommodating part 103 is provided. The area for heating the asphalt 190 is widened so that the solid asphalt 190 can be quickly melted and melted without changing the physical properties by indirect heating.

When the heat transfer medium is heated by the heater 111, the volume of the heat transfer medium expands, so that the heating chamber 110 is not filled in the heating chamber 110, but only a predetermined amount is filled in the heating chamber 110 in consideration of the expanded volume. Done.

In addition, the receiving portion 103 is provided with an impeller 140 having a plurality of wings 141 is provided by the fixing member 143 coupled to the same line on the front and rear of the receiving portion 103, the impeller ( A driven bevel gear 142 is formed at one side of the 140 and is engaged with the main bevel gear 132 coupled to the lower portion of the drive shaft 131 which is rotated by the drive motor 130 installed at the upper portion of the housing 101. .

On the other hand, since the configuration for supplying power to the plurality of heaters 111 and the drive motor 130 can be generally applied to anyone in a variety of configurations, a detailed description thereof will be omitted.

The auxiliary burner 104 installed below the heating chamber 110 is a burner using LPG as a raw material, and when the power supplied to the heater 111 of the heating chamber 110 is disconnected, the auxiliary burner 104 is used. It is preferable to continuously heat the heat transfer medium of the heating chamber 110 by driving the. At this time, the coupling position and the number of installation of the auxiliary burner 104 may be varied depending on the capacity of the accommodating part 103 and the capacity of the heating chamber 110 and the like.

Therefore, when the drive motor 130 is rotated, the rotational force of the drive shaft 131 is transmitted to the driven bevel gear 142 through the driving bevel gear 132, the impeller 140 is rotated, to the impeller 140 The combined plurality of wings 141 also rotate and circulate in the accommodating part 103 to accommodate the melted asphalt in the accommodating part 103 so that the asphalt in the accommodating part 103 has a uniform temperature as a whole and melts.

At this time, the drive shaft 131 penetrates the through hole 134 of the support member 133 coupled to the receiving part 103 and is installed perpendicular to the receiving part 103 so as to be firmly fixed.

And the plurality of wings 141 coupled to the impeller 140, but circulating the asphalt accommodated in the receiving portion 103, may be combined by setting all at the same angle to circulate the asphalt in a certain direction, the central portion In both directions, or may be combined by varying the angle of the wing 141 to circulate the asphalt to the central portion in both directions.

On the other hand, by transmitting the rotational force of the drive shaft 131 to the impeller 140 installed perpendicular to the drive shaft 131 can be configured as a power transmission device of another configuration that the impeller 140 can rotate, of course, It will be said that it belongs to the scope of the present invention.

In addition, on the side of the door 102 side of the housing 101, a guide 170 made of a "┌┐" shape is vertically opposed by a plurality of supports 171 connected to the side of the housing 101 Is installed.

In addition, both side plates 180 having a plurality of feed shafts 181 coupled with a plurality of feed rollers 182 horizontally arranged on the same line are installed between the guides 170. 2) The lifting roller 184, which is inserted into the guide 170 at both ends of the lifting shaft 183, which is connected to each other, is freely coupled to the side plate 180 to move up and down between the guides 170.

In this case, the cylinder cylinder 161 connected to the lower portion of the elevating shaft 183 by using the connector 162 is elevated by the hydraulic cylinder 160 using the power of the driving unit 150 to guide both guides 170. Both side plates 180 are provided with a plurality of feed rollers 182 and the lifting operation is received, the height of the side plate 180 is raised so that the feed roller 182 is located in the door 102 of the housing 101 Of course, it should be set higher than the secondary height, the side plate 180 is lowered, the height of the feed roller 182 is preferably positioned so that slightly above the knee when the operator stands on the ground.

This is to push the solid asphalt 190 placed on the transfer roller 182 to the receiving part 103 through the door 102, and the driving part 150 supplies the power required by the hydraulic cylinder 160. As the generating device, such a device is commonly used, so a detailed description thereof will be omitted.

And both sides of the lower side of the side plate 180 is in contact with the side of the guide 170, the support roller 185 which is free to rotate is coupled to both sides of the plate 180 is inclined by the load of the solid asphalt 190 Of course, the support roller 185 should be located further lower than the lifting roller 184.

On the other hand, the configuration to elevate the both side plate 180 is not to the hydraulic cylinder 160, but also to be configured to other configurations belong to the scope of the technical idea of the present invention, for example, by installing a sprocket at the end of the lifting shaft, It is also possible to configure the guide connected to the sprocket and the chain driven by the motor to guide the lifting operation of both side plates on the outside of both side plates.

Referring to the operation of the present invention a melting device in detail as follows.

First, the electric power is supplied to the plurality of heaters 111 to heat the heat transfer medium filled in the heating chamber 110 and the auxiliary heating chamber 120, and thus, the asphalt in the solid state remaining in the accommodating part 103. To melt.

Then, after placing the solid asphalt 190 on the plurality of feed rollers 182, the hydraulic cylinder 160 is operated to transfer the solid asphalt 190 to the upper side of the housing 101, and the door 102 Open and push the solid asphalt 190 to the receiving portion 103 to close the door 102.

At this time, the feed roller 182 is coupled to the feed shaft 181 through a roller, so that the free rotation, it is possible to easily push the solid asphalt 190 to move.

In addition, since the solid asphalt 190 is heavy, it is difficult for the worker to enter the upper portion of the housing 101 and put it in the receiving portion 103 through the door 102, but the position where the feed roller 182 is lowered. Since the position is about the knee when standing on the ground, the operator is very easy to place the solid asphalt 190 on the transfer roller 182, the hydraulic cylinder 160 is operated to the upper portion of the housing 101 After the solid asphalt 190 is transferred, the solid asphalt 190 is pushed in the direction of the door 102 so that the solid asphalt 190 can be easily introduced into the receiving part 103.

In addition, the side plate 180 is prevented from inclining due to the load of the solid asphalt 190 by the support roller 185.

Meanwhile, the heater 111 continuously dissipates heat and heats the heat transfer medium of the heating chamber 110 to melt the solid asphalt 190. After the asphalt is melted to some extent, the driving motor 130 is turned on. The drive shaft 131 is rotated by driving, and the impeller 140 rotates to circulate the asphalt in the accommodating part 103.

After the asphalt in the accommodating part 103 is heated to 150 ° C to 210 ° C and completely melted, the electric power supplied to the heater 111 installed in the auxiliary heating chamber 120 is cut off to be installed in the heating chamber 110. Power is continuously supplied only to the heater 111 to maintain the temperature of the asphalt.

Therefore, the molten state of the asphalt can be maintained even while the work is stopped for a long time, thereby avoiding the trouble of melting the asphalt from the beginning and the waste of the heat source.

In this case, although not shown in the drawing, the thermometer 103 for measuring the temperature of the asphalt in the receiver 103 is installed, and is supplied to the heater 111 according to the measured temperature of the thermometer. Of course, the control unit for controlling the power is also configured, and of course, the discharge port for discharging the molten asphalt to the outside in the receiving portion 103 is provided.

In addition, the present invention can be used to install the heating melting apparatus 100 in the work site, or installed in a vehicle to facilitate the movement.

As described above, with regard to the heat melting apparatus of the present invention, various design changes of the respective components within the scope of the present invention are all considered to be included in the scope of the technical idea of the present invention.

As described above, the present invention forms a heating chamber filled with a heat transfer medium so as to surround the front and rear surfaces and the lower surface of the accommodating portion in which the solid asphalt is accommodated, and a plurality of heaters are installed in the heating chamber, By allowing the heat transfer medium of the heating chamber heated by the heater to melt the asphalt in the solid state accommodated in the accommodating portion, the heat transfer medium in the heating chamber can be quickly heated, thereby quickly melting the asphalt in the solid state of the accommodating portion. Since it is possible to shorten the time to melt the asphalt, there is an effect that can improve the work efficiency.

In addition, the deformation of the components generated when melting the asphalt in the accommodating part into hot asphalt does not occur in the melting apparatus of the present invention, and even if the deformation occurs, the gap caused by the deformation is not formed, so that the asphalt in the accommodating part is not formed. It also has the effect of not leaking.

That is, conventionally, the combustion chamber is installed horizontally, and the first pipeline part which is coiled horizontally is installed inside the combustion chamber, and the upper and lower second pipeline parts which are coiled horizontally are installed outside the combustion chamber. As a result, deformation occurs in the lower portion of the high temperature heat in the state of melting the asphalt as a result, which causes a gap in the coupling part of the combustion chamber and the housing, causing the asphalt to leak.

In addition, the coupling between the drive motor and the housing to circulate the asphalt in the receiving portion is water-tightness due to the high temperature heat and the gap is generated there is a problem that the asphalt leaks to this place, further melted in the coupling portion of the drive motor and the housing As the asphalt is located, leakage occurs due to the generation of gaps.

However, in the melting apparatus of the present invention, the impeller and the auxiliary heating chamber are installed horizontally in the receiving portion, but all of them are firmly fixed to both sides of the receiving portion, and even if the bending deformation occurs, the operation of the melting apparatus will not be affected at all. In addition, even if all of them are installed in the receiving portion, even if a gap occurs, the asphalt does not occur to the outside of the melting apparatus.

In addition, the driving motor for rotating the impeller is coupled to the upper portion of the housing so that the asphalt leakage to the coupling portion of the driving motor and the housing does not occur at all, thereby smoothly working.

That is, when the asphalt in the solid state in the receiving portion is not filled in the receiving portion, but only the amount corresponding to about 70 ~ 90% of the total volume of the receiving portion, the asphalt is in the coupling portion of the drive motor and the housing Contact does not occur, and even if a gap is generated in this part, the asphalt does not leak.

In addition, since the asphalt is completely enclosed in the receiving portion, even if other components are deformed by heat, there is no part where the asphalt leaks.

On the other hand, conventionally, the high temperature heat generated by the burner heats the heat transfer medium filled in the first pipe part in the combustion chamber, and the upper and lower agents provided with the heat transfer medium in the first pipe part by the circulation pump are installed in the receiving part. By heating the asphalt through the two pipelines, there is a disadvantage that the circulation pump must be constructed, as well as the heat transfer medium passes through the long pipeline and heats the asphalt in the solid state, resulting in high heat loss. There was also a disadvantage that can not quickly melt the asphalt.

In addition, since the heat transfer medium must be forcedly circulated by the circulation pump, there is a big disadvantage that the melter cannot be used when the circulation pump fails.

However, in the present invention, since the heater coupled to the heating chamber is operated while the heat transfer medium is filled in the heating chamber to heat the entire heat transfer medium of the heating chamber, there is almost no heat loss, so that the entire heat transfer medium can be quickly heated. As a result, the solid asphalt in the receiving part can be quickly heated and melted, and power can be supplied even when the work is stopped to maintain the molten state of the asphalt.

In addition, since the solid asphalt can be easily supplied to the receiving portion through the door by the hydraulic cylinder and the transfer roller as described above, it is possible to increase the working efficiency of the operator, thereby reducing the working time.

In addition, even when the power supplied to the heater is interrupted, since the heat transfer medium of the heating chamber can be continuously heated by using the auxiliary burner, there is an effect of preventing the work interruption due to the interruption.

As described above, the present invention can be melted by heating the solid asphalt quickly, and can maintain the molten state of the asphalt even when the operation is interrupted, even if the deformation occurs in the component due to high temperature heat As the asphalt inside is not leaked to the outside, it is a useful invention for smooth operation at a very safe and low cost.
