[0028] See attached Figure 1-3 The embodiment of the present application provides an environmentally friendly and recyclable dual-cooperative heating device for pavement materials, including a tank body 1, a first heating component 2 and a second heating component 3, wherein: the tank body 1 includes an inner tank, and a sandwich 13 is formed between the inner tank and the shell of the tank body 1. The inner tank is used to hold the material to be heated. The tank body 1 can be installed by setting support legs 14. The first heating component 2 includes a heating rod 21 arranged in the inner tank. The second heating component 3 includes a steam delivery pipe 31 and a delivery controller 33. One end of the steam delivery pipe 31 is connected to the tank body 1 and communicates with the sandwich 13. A steam inlet 12 is formed on the tank body 1. The other end of the steam delivery pipe 31 is connected to the delivery controller 33. The delivery controller 33 is used to control the steam flow direction inside the steam delivery pipe 31.

[0029] In this embodiment, the tank body 1 is set as a two-layer structure, the inner tank is used to hold the material to be heated, and a first heating component 2 is provided for heating using a heating rod, and a second heating component 3 is provided for dual collaborative heating. The second heating component 3 adopts steam heating, and the high-temperature steam is transported to the interlayer 13 formed between the inner tank and the shell of the tank body 1 through the steam delivery pipe 31, and the steam flow direction is controlled by the delivery controller 33, which is conducive to circulation replacement. The heating rod 21 realizes internal insertion heating of the material, and the steam realizes external wrapping heating of the material, which improves the heating efficiency while avoiding the influence of the single heating method on the use environment conditions, and significantly improves the heating effect.

[0030] In the embodiment of the present application, the source of the steam inside the steam delivery pipe 31 can be a steam generator. If a boiler is used in the factory, the boiler can be used to generate high-temperature steam, and the steam enters the interlayer 13 through the drainage of the pipeline. The delivery controller 33 is equivalent to a flow rate controller, and a power device such as a blower is arranged inside to change the flow rate and direction of the steam in the pipeline. It is mainly used for changing the direction to facilitate the passage of steam into or out of the interlayer 13. Under long-term use, condensed water will inevitably accumulate in the interlayer 13. At this time, a water outlet connected to the interlayer 13 can be opened at the bottom of the tank body 1 to remove the condensed water.

[0031] In one embodiment, the first heating component 2 also includes a motor 23, which is arranged on the top of the tank body 1, the axis of the heating rod 21 coincides with the axis of the tank body 1, the driving shaft of the motor 23 is connected to one end of the heating rod 21, and the other end of the heating rod 21 extends into the inner tank.

[0032] As in the above embodiment, by setting a motor 23 on the top of the tank body 1, the heating rod 21 has the ability to rotate and has a certain stirring ability for the material, and the heating rod 21 is set to be located in the center of the inner tank in a vertical state, so that its heat can be radiated evenly to the surroundings, thereby improving the heating effect. In order to enhance the heating effect of the stirring effect, a plurality of stirring components 22 are provided on the heating rod 21, such as stirring blades, stirring rods, and spirally extended stirring surfaces, to increase the stirring contact surface area. In order to cooperate with the feeding port 11 of the tank body 1 set at the top of the tank body 1, one end of the stirring component 22 is connected to the heating rod 21, and the other end of the stirring component 22 is inclined and extends downward in a direction away from the heating rod 21. On this basis, as shown in the attached Figure 3 The stirring member 22 is shown in the form of a stirring rod, which is arranged to be tilted downward so that the material falling from the feeding port 11 can fall along the stirring member 22 after being blocked by the stirring member 22 .

[0033] In one embodiment, as shown in the attached Figure 1 As shown, in order to avoid reducing the heating effect after the steam is introduced, the passage is usually closed to form a closed state between the interlayer 13 and the steam delivery pipe 31. In order to avoid safety hazards caused by the internal pressure when the passage is opened, a pressure relief valve 32 can be added to the second heating component 3. The pressure relief valve 32 is set on the steam delivery pipe 31. After the heating is completed, part of the internal pressure is released through the pressure relief valve 32, and then other operations such as material recovery are carried out.

[0034] In one embodiment, a discharging assembly 4 is provided to assist in collecting the heated material. Figure 2 As shown, the discharge port of the tank body 1 is arranged at the bottom of the tank body 1, and the device further comprises a discharge assembly 4, which comprises a first discharge pipe 42 connected to the discharge port. The first discharge pipe 42 is arranged at the bottom of the tank body 1 to guide the flow and collection of materials. The first discharge pipe 42 is controlled on and off by a valve, and a flange valve 41 can be adopted. The flange valve 41 is arranged on the first discharge pipe 42, which has the characteristics of easy disassembly and replacement, and the contact pressure can be adjusted by the adjusting nut between the sealing surfaces, so that the valve has good sealing performance, and the heating effect inside the tank body 1 is further improved.

[0035] In one embodiment, the discharge assembly 4 also includes a second discharge pipe 44, one end of the first discharge pipe 42 is connected to the discharge port, and the other end of the first discharge pipe 42 is connected to the conveying controller 33. The conveying controller 33 is also used to control the discharge speed. One end of the second discharge pipe 44 is connected to the middle part of the first discharge pipe 42. The conveying controller 33 is used to assist the discharge flow of the first discharge pipe 42 by providing power in different directions when the heating work is completed. In this case, the final discharge is achieved through the second discharge pipe 44.

[0036] In one embodiment, since the recycling of some special materials may involve the addition of auxiliary materials, after the second discharge pipe 44 is used to assist in the discharge, a hopper 43 can be set on the original first discharge pipe 42. The small-diameter end of the hopper 43 is connected to the first discharge pipe 42. Through the hopper 43, other auxiliary materials can be added while discharging, such as some solid or liquid additives. When no auxiliary materials are added, the hopper 43 can be used as an observation port for the flow state of the material. Further, a valve can be set on the hopper 43 to control the feeding speed of the hopper 43. The valve here not only needs to realize the control of the outlet opening and closing, but also needs to realize the control of the outlet size. The speed of the material falling into the first discharge pipe 42 can be controlled by the degree of closing or opening.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
