[0063] Example 2

[0064] like Figures 1 to 5 As shown, this embodiment designs a feeding mechanism 1 for asphalt concrete raw materials, including a feeding frame 105, a storage hopper 103, a weighing hopper 104, a first conveyor belt 101, a second conveyor belt 102 and other components.

[0065] The loading rack 105 adopts a frame structure and is formed with three layers: upper, middle and lower.

[0066] A plurality of storage hoppers 103 are arranged in a straight line and fixedly mounted on the upper layer of the loading frame 105. The storage hoppers 103 have an oblique conical hopper structure. The discharge ports of different storage hoppers 103 have different orientations, so that the discharge ports of different storage hoppers 103 can be tilted toward the second conveyor belt 102 or the first conveyor belt 101 respectively.

[0067] A weighing hopper 104 is correspondingly arranged below each storage hopper 103, that is, the storage hoppers 103 and the weighing hoppers 104 are in a one-to-one correspondence, and several weighing hoppers 104 are installed on the middle layer of the loading frame 105. The discharge port of the storage hopper 103 is located directly above the feed port of the weighing hopper 104, and the discharge port of the storage hopper 103 is downwardly aligned with the feed port of the weighing hopper 104, so that the raw materials in the storage hopper 103 can fall into the weighing hopper 104.

[0068] The weighing hopper 104 is connected to the feeding frame 105 via a raw material weighing sensor 111, so that the weighing hopper 104 can weigh the raw materials, so as to proportion the raw materials of asphalt concrete during the production of asphalt concrete.

[0069] The first conveyor belt 101 and the second conveyor belt 102 are arranged in parallel and installed on the lower layer of the loading frame 105, and the output ends of the first conveyor belt 101 and the second conveyor belt 102 extend from the same direction of the loading frame 105; when the raw materials in the weighing hopper 104 fall onto the first conveyor belt 101 or the second conveyor belt 102, the raw materials can be transported to the equipment of the next production link through the first conveyor belt 101 or the second conveyor belt 102.

[0070] The loading rack 105 includes a raw material station and a recycled material station, each of which is provided with at least one storage hopper 103; the discharge port of the weighing hopper 104 at the raw material station extends to above the first conveyor belt 101, and the discharge port of the weighing hopper 104 at the recycled material station extends to above the second conveyor belt 102; the discharge ports of the storage hopper 103 and the weighing hopper 104 are both provided with movable valve plates 108, and when the corresponding valve plates 108 are removed, the raw materials at the raw material station can fall onto the first conveyor belt 101, and the raw materials at the recycled material station can fall onto the second conveyor belt 102.

[0071] A horizontal discharging auger 112 is provided at the outlet of the storage hopper 103 at the recycled material station. The discharging auger 112 is driven by an auger motor 110. The auger motor 110 is arranged outside the storage hopper 103, and the output shaft of the auger motor 110 is connected to the discharging auger 112 in a transmission manner. When the auger motor 110 is started, the discharging auger 112 rotates and stirs the raw materials in the storage hopper 103, thereby reducing the probability of clogging of the recycled raw materials in the storage hopper 103 due to their own viscosity.

[0072] A vibration motor 106 is installed on the outer side wall of part or all of the storage hoppers 103, and a vibration motor 106 is installed on the weighing hopper 104 of part or all of the storage hoppers 103. The vibration motor 106 is used to vibrate the raw materials in the storage hopper 103, thereby reducing the probability of blockage at the discharge port of the storage hopper 103 or the weighing hopper 104.

[0073] The valve plate 108 is a long strip structure, and the shape and size of the valve plate 108 match the discharge port of the storage hopper 103 or the material hopper 104. The two ends of the valve plate 108 are rotatably connected to the shaft at the discharge port through respective swing arms 109. The shaft at the discharge port can cross the storage hopper 103 or the material hopper 104, and the valve plate 108 is rotated to a position staggered with the corresponding discharge port, thereby realizing the opening of the discharge port to facilitate the falling of the raw materials; the valve plate 108 can also be rotated to a position directly opposite to the corresponding discharge port, thereby realizing the closing of the discharge port, thereby blocking the falling raw materials.

[0074] A driver 107 is connected between the valve plate 108 and the weighing hopper 104. The driver 107 is a telescopic hydraulic cylinder or a telescopic electric cylinder, and the driver 107 is used to control the rotation of the valve plate 108. The cylinder body of the telescopic hydraulic cylinder or the telescopic electric cylinder can be rotatably connected to the outer wall of the storage hopper 103 or the weighing hopper 104, and the telescopic rod of the telescopic hydraulic cylinder or the telescopic electric cylinder is rotatably connected to the side edge of the valve plate 108.

[0075] The output ends of the first conveyor belt 101 and the second conveyor belt 102 are tilted upward, so as to achieve height increase during raw material transportation.

[0076] When the feeding mechanism 1 of this embodiment is used: raw materials are loaded into the storage hopper 103 at the raw material station according to different categories, or / and recycled materials are loaded into the storage hopper 103 at the recycled material station according to different categories; when feeding is required, according to actual needs, the valve plate 108 at the storage hopper 103 is opened to allow the raw materials to fall into the weighing hopper 104 until the weight of the raw materials in the weighing hopper 104 meets the set requirements. Then, the valve plate 108 at the weighing hopper 104 is opened to allow the raw materials in the weighing hopper 104 to fall onto the first conveyor belt 101 or the second conveyor belt 102 to convey the raw materials.

The temporary storage bucket 801 is rotatably connected to the temporary storage valve plate 808 through the valve plate connecting arm 809, so that the weight of the raw materials at the valve plate 108 can be transferred to the temporary storage bucket 801, thereby facilitating the accurate measurement of the temporary storage material weighing sensor 803.

[0083] An outer shield 805 is provided on the periphery of the discharge port of the temporary storage bucket 801, and the outer shield 805 is used to block the gap between the material guide chute 806 and the discharge port of the temporary storage bucket 801, so as to achieve a dustproof effect.

The raw material burner 701 is provided with an air inlet and a gas interface, and the gas burns in the raw material burner 701, and after mixing with air to form hot air, it is sent into the raw material roller body 705 through the switching cylinder 702.

[0091] A roller ring rail 703 is arranged outside the raw material roller body 705. Generally, two roller ring rails 703 are connected to the raw material roller body 705, one in front and one in the back. The roller ring rail 703 is coaxial with the raw material roller body 705 and relatively fixed. The raw material roller body 705 is horizontally arranged above the support roller 707, and a plurality of the support rollers 707 are in contact with the roller ring rail 703 and support the raw material roller body 705. Each roller ring rail 703 can be supported by two support rollers 707, one on the left and one on the right.

[0092] A support sheet 704 is provided between the inner wall of the roller ring rail 703 and the outer wall of the raw material roller body 705. The support sheet 704 is inclined to the radial direction of the roller ring rail 703. The outer end of the support sheet 704 is fixedly connected to the roller ring rail 703, and the inner end of the support sheet 704 is against the raw material roller body 705.

[0093] A plurality of turning blades 710 are arranged on the inner wall of the raw material roller body 705. The turning blades 710 can be arranged in a stepped distribution in the length and height direction of the raw material roller body 705. The turning blades 710 are used to turn the raw material of asphalt concrete. The turning blades 710 are distributed in the roller section.

[0094] A plurality of guide blades 711 are also provided on the inner wall of the raw material roller body 705. The guide blades 711 extend from the roller section to the front cone section. The guide blades 711 are inclined to the circumferential and axial directions of the raw material roller body 705. The guide blades 711 are used to guide the raw material forward or backward. The guide blades 711 are used to add raw material to asphalt concrete or to deliver asphalt concrete.

[0095] The upper part of the raw material front barrel mouth is provided with a raw material inclined bucket 708, which is used to introduce the raw material of asphalt concrete into the raw material roller body 705. The lower part of the raw material front barrel mouth forms a raw material outlet 709, which is used to discharge the asphalt concrete in the raw material roller body 705.

[0096] The support roller 707 is rotatably arranged on the support seat 706, and the number of the support rollers 707 can correspond to the support seat 706 one by one, and at least one of the support rollers 707 is connected to the stirring motor. When the stirring motor rotates, the support roller 707 is driven, and the support roller 707 drives the raw material roller body 705 to flip under the action of friction, thereby achieving the stirring of the raw material of the asphalt concrete.

[0097] The raw material stirring roller mechanism 7 in this embodiment is used:

[0098] The raw material of asphalt concrete is sent into the raw material roller body 705 from the raw material front barrel mouth through the raw material inclined hopper 708. The raw material roller body 705 rotates forwardly under the drive of the stirring motor, thereby guiding the raw material of asphalt concrete backward, and turning and mixing it under the joint action of the guide blade 711 and the turning blade 710. In this process, the raw material burner 701 sends heated air into the raw material roller body 705 to heat the raw material of asphalt concrete, thereby ensuring the fluidity of the raw material of asphalt concrete.

[0099] After the asphalt concrete is mixed, the raw material roller body 705 rotates in the opposite direction under the drive of the mixing motor, and the guide blades 711 guide the asphalt concrete forward, so that the asphalt concrete is discharged outward from the raw material outlet 709 at the raw front barrel mouth. After it is completely discharged, a new round of asphalt concrete mixing can be carried out.

[0100] Example 5

[0101] like Figure 1 and Figure 12 to Figure 14 As shown, this embodiment designs a recycled material stirring roller mechanism 6 for asphalt concrete, including components such as a heat insulation cover 611, a recycled material roller body 604, a recycled material burner 608, a deflector pipe 601 and a negative pressure pipe 609.

[0102] The heat shield 611 is in a horizontal cylindrical shape and is used for heat insulation of the recycled material roller body 604, thereby improving the heat utilization rate. The heat shield 611 is a multi-faceted three-dimensional structure formed by splicing plates. The heat shield 611 is spliced ​​in a flat plate shape, which can reduce the processing difficulty of the heat shield 611. It only needs to weld and splice the plates. The rear end of the heat shield 611 is a vertical plate with a hole in the middle. The outer wall of the heat shield 611 is spliced ​​with rectangular plates, and the front end of the heat shield 611 is a conical structure spliced ​​with fan-shaped plates.

[0103] An inner splicing plate 612 is arranged on the inner wall of the heat insulation cover 611 , and a heat insulation filling material is arranged between the inner splicing plate 612 and the heat insulation cover 611 , so as to improve the heat insulation and thermal insulation performance.

[0104] The recycled material roller body 604 is arranged in a horizontal position in the heat insulation cover 611 and can rotate in both forward and reverse directions; the front end and the rear end of the recycled material roller body 604 are both conical, and the middle part of the recycled material roller body 604 is cylindrical.

[0105] An external heating chamber is formed between the heat insulation cover 611 and the recycled material roller body 604, and the external heating chamber is connected to the outlet of the recycled material burner 608 to utilize hot air to heat the recycled material roller body 604. The continuous rotation of the recycled material roller body 604 can make the recycled material roller body 604 be heated more evenly, thereby improving the heating efficiency of the recycled material roller body 604.

[0106] The front end of the recycled material roller body 604 extends out of the heat insulation cover 611 and is provided with a regeneration front barrel opening, which is connected to the negative pressure pipe 609 so as to utilize the negative pressure pipe 609 to suck the air in the recycled material roller body 604; specifically: the front end of the recycled material roller body 604 has an extension tube head 607, and the front tube opening of the extension tube head 607 is the regeneration front barrel opening, which is inserted into the negative pressure pipe 609, and the extension tube head 607 can rotate relative to the negative pressure pipe 609, and the negative pressure pipe 609 can be connected to the blower, so as to form a negative pressure in the recycled material roller body 604, so that the hot air generated by the recycled material burner 608 can enter the recycled material roller body 604 and directly heat the recycled material.

[0107] The rear end of the recycled material roller body 604 extends out of the heat insulation cover 611 and is provided with a regeneration rear barrel opening. The external heating chamber introduces hot air into the regeneration rear barrel opening through the baffle pipe 601. The regeneration rear barrel opening is used for the entry of hot air and for the entry and discharge of recycled materials of asphalt concrete. Specifically, a recycled material inclined bucket 602 is provided at the upper half of the regeneration rear barrel opening. The recycled material inclined bucket 602 is used to introduce the recycled materials of asphalt concrete into the recycled material roller body 604. The lower half of the regeneration rear barrel opening forms a recycled material outlet 613, which is used to discharge the materials in the recycled material roller body 604. Baffle pipes 601 can be provided on the left and right sides of the recycled material inclined bucket 602 at the regeneration rear barrel opening to increase the flow of hot air.

[0108] The inner wall of the recycled material roller body 604 is provided with a spiral blade 606, which is used for stirring and guiding the recycled material. The spiral blade 606 provided on the inner wall of the recycled material roller body 604 is a double spiral structure. The double spiral structure can make the distribution of the spiral blade 606 more symmetrical and reduce the eccentricity of the center of gravity of the recycled material roller body 604. A transverse blade 605 is also provided on the inner wall of the recycled material roller body 604, and the transverse blade 605 is connected with the spiral blade 606 along the front and rear ends of the transverse blade 605, so as to avoid the recycled material flowing only along the channel at the spiral blade 606, which affects the heating efficiency of the recycled material.

[0109] A front ring rail 610 is provided on the outer surface of the extension tube head 607, and the front ring rail 610 is coaxial with the recycled material roller body 604 and relatively fixed; a rear ring rail 603 is provided on the outer side of the rear end of the recycled material roller body 604, and the rear ring rail 603 is coaxial with the recycled material roller body 604 and relatively fixed; the front ring rail 610 and the rear ring rail 603 are both located outside the heat insulation cover 611, and matching driving wheels are respectively provided below the front ring rail 610 and the rear ring rail 603, and the driving wheels are used to control the forward and reverse bidirectional rotation of the recycled material roller body 604. The driving wheel cooperates with the annular surface of the front ring rail 610 or the rear ring rail 603, and drives the recycled material roller body 604 through friction, so that the recycled material roller body 604 can rotate forward or reverse.

[0110] When the recycled material stirring roller mechanism 6 in this embodiment is used:

[0111] The recycled material of asphalt concrete is sent into the recycled material roller body 604 from the regenerated barrel mouth through the recycled material inclined hopper 602. The recycled material roller body 604 rotates forward under the control of the driving wheel, thereby guiding the recycled material of asphalt concrete forward, and is turned over and mixed under the joint action of the spiral blade 606 and the transverse blade 605.

[0112] In the above process, the recycled material burner 608 sends the heated air into the external heating chamber, so that the recycled material roller body 604 is heated, thereby indirectly heating the recycled material inside it and ensuring the fluidity of the recycled material of the asphalt concrete. Then the hot air is sent into the recycled material roller body 604 through the deflector pipe 601. Under the negative pressure of the recycled material roller body 604, the hot air flows forward and directly heats the recycled material. Then the hot air is discharged through the negative pressure pipe 609.

[0113] After the asphalt concrete is mixed, the recycled material roller body 604 rotates in the opposite direction, and the spiral blades 606 guide the asphalt concrete backward, so that the asphalt concrete is discharged outward from the recycled material outlet 613 at the drum mouth after regeneration. After it is completely discharged, a new round of recycled material processing can be carried out.

[0114] Example 6

[0115] like Figure 1 and Figures 15 to 17 As shown, this embodiment designs a heat recovery asphalt storage tank, which includes two main parts: a heat medium box 91 and an asphalt tank body 92 , wherein the asphalt tank body 92 is located above the heat medium box 91 .

[0116] The asphalt tank 92 is used to store asphalt slurry, and the asphalt tank 92 is circular or oval, or the asphalt tank 92 adopts an upright or horizontal polygonal structure. In order to achieve heat preservation of the asphalt tank 92, the tank wall of the asphalt tank 92 can be filled with insulating materials such as foaming agent and sponge.

[0117] An asphalt extraction port 921 is provided on the tank wall of the asphalt tank body 92; asphalt slurry can be injected into the asphalt tank body 92 through the asphalt extraction port 921, and the asphalt slurry in the asphalt tank body 92 can also be extracted out. The position of the asphalt extraction port 921 can be set on the top wall or the side wall of the asphalt tank body 92.

[0118] An openable cover plate 93 is provided on the asphalt extraction port 921 ; the cover plate 93 can be rotatably connected to the edge of the asphalt extraction port 921 , so that the asphalt extraction port 921 can be shielded or covered by the cover plate 93 .

[0119] The heat medium box 91 is arranged below the asphalt tank body 92 , and a heat exchange cavity is arranged in the heat medium box 91 . The heat exchange cavity can use the bottom wall of the asphalt tank body 92 as the cavity wall of the heat exchange cavity, so that the heat medium box 91 can exchange heat with the asphalt tank body 92 .

[0120] A supporting baffle 94 is provided in the heat exchange chamber, and the supporting baffle 94 divides the heat exchange chamber into an S-shaped channel. An inlet 912 and an outlet 911 are provided on the box wall of the heat medium box 91, and the inlet 912 and the outlet 911 are respectively located at the two ends of the S-shaped channel.

[0121] The outlet 911 and the inlet 912 are provided with temperature sensors 95 , so as to measure the temperature of the heat medium when it enters and exits the heat exchange chamber. The outlet 911 and the inlet 912 can be provided on the side wall of the heat medium box 91 on the same side.

[0122] There are a plurality of support baffles 94. Specifically, the number of support baffles 94 is generally one. Adjacent support baffles 94 are staggered with each other. When the number of support baffles 94 is three, the support baffles 94 form the structure shown in the figure.

[0123] The upper edge of the support baffle 94 is connected to the upper cavity wall of the heat exchange cavity, and the lower edge of the support baffle 94 is connected to the lower cavity wall of the heat exchange cavity to achieve vertical support of the asphalt tank body 92, thereby improving the support stability and reliability of the support baffle 94.

[0124] The supporting baffle 94 is a long strip plate, one end of which is connected to the side wall of the heat exchange chamber, and the other end of which is spaced from the side wall on the opposite side of the heat exchange chamber.

[0125] When the heat recovery asphalt storage tank in this embodiment is in use, the heat medium enters the heat medium box 91 through the inlet 912. During the flow of the heat medium along the S-shaped channel, heat is exchanged with the partition and the bottom wall of the asphalt tank body 92, so that the asphalt in the asphalt tank body 92 is heated, thereby ensuring that the asphalt is in a liquid state during temporary storage. The source of the heat medium can be any other process link in the asphalt processing process, and the heat medium can be hot water, hot air, water vapor, etc.

[0126] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
