Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for asphalt mixing plants, and in particular to a recycled virgin dual-material drying drum for a fully mobile 120t asphalt mixing plant. Background Technology

[0002] Asphalt mixing plants are key equipment in mechanized asphalt pavement construction, and their operation directly affects the quality and speed of pavement construction. The drying system is one of the important components of an asphalt mixing plant, and its main function is to heat and dry aggregates to the required temperature.

[0003] Currently, Chinese patent CN204401405U discloses a waste heat utilization device for the drying drum of an asphalt mixing plant. The device includes a support base and a drying drum rotatably mounted on the support base, driven by a drive mechanism. One end of the drying drum is a feed inlet, and the other end is a discharge pipe. A burner is installed at the feed inlet. The drying drum has an air inlet and an air outlet. A heat-conducting oil pipe is spirally arranged on the outer surface of the drying drum, fixed relative to the support base. One end of the heat-conducting oil pipe is an oil inlet, and the other end is an oil outlet. The oil outlet is connected to a heating source, and the oil inlet is connected to an oil pump. The high temperature on the surface of the drying drum is recovered and utilized through the heat-conducting oil for heating or preheating other materials. Furthermore, the burner burns only oil residue and heavy oil, resulting in low cost, energy saving, environmental protection, and improved production efficiency.

[0004] In the aforementioned waste heat recovery device for the drying drum of the asphalt mixing plant, the aggregate enters the drying drum through the inlet, and the burner is located at the inlet to heat the aggregate. Since the inlet temperature is higher than the outlet temperature, the aggregate slides along the drying drum and moves directly towards the outlet for discharge. Because the heating time at the inlet is relatively short, the aggregate often fails to reach the required temperature before leaving the inlet and moving towards the outlet for discharge. This results in the aggregate not reaching the desired temperature due to the short heating time.

[0005] Therefore, this application proposes a recycled virgin dual-material drying drum for a fully mobile 120t asphalt mixing plant to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a recycled virgin dual-material drying drum for a fully mobile 120t asphalt mixing plant.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A recycled virgin dual-material drying drum for a fully mobile 120t asphalt mixing plant includes a recycled virgin dual-material drying drum for the asphalt mixing plant, a bottom plate, a drying mechanism, and a feeding mechanism.

[0009] A recycled virgin dual-material drying cylinder is fixedly installed on the base plate. A drying mechanism is provided inside the recycled virgin dual-material drying cylinder, and a feeding mechanism is provided on one side of the recycled virgin dual-material drying cylinder.

[0010] The drying mechanism includes a burner, a guide tube, a spiral plate, a temperature sensor, and a motor. A bracket is fixedly installed on the top of the recycled and virgin dual-material drying cylinder. The burner and control panel are mounted on the bracket, and the burner is connected to the control panel. A guide tube is rotatably connected inside the recycled and virgin dual-material drying cylinder, with one end rotatably connected to the heating end of the burner. A spiral plate is fixedly installed on the guide tube. Through the coordinated design of the recycled and virgin dual-material drying cylinder, the drying mechanism, the feeding mechanism, and the control panel, the flame distance emitted by the burner can be extended, and the time the flame acts on the raw material can be increased, thereby greatly improving the drying effect and product quality. Furthermore, through the coordinated action of the circulation pipe, the feeding pipe, the spiral rod, and the motor, the raw material can be dried in a circulating manner according to user needs, improving flexibility.

[0011] Specifically, the spiral plate is adapted to the recycled and virgin dual-material drying cylinder. A temperature sensor is fixedly installed at one end of the guide tube. The temperature sensor is connected to the control panel. The temperature sensor can monitor the temperature inside the recycled and virgin dual-material drying cylinder and transmit the monitored information to the control panel. The control panel analyzes and judges the information with the preset program and adjusts the power of the burner, thereby achieving the effect of regulating the temperature inside the recycled and virgin dual-material drying cylinder and further improving product quality.

[0012] Specifically, the guide tube is provided with multiple heat transfer holes, each of which corresponds to the gap of the first spiral plate, for heating and drying the raw material in the gap of the first spiral plate.

[0013] Specifically, a second electric motor is fixedly installed on the bracket, and a gear is fixedly connected to the output end of the second electric motor. A gear ring is meshed on the gear, and the gear ring is fixedly sleeved on the guide tube. Driven by the second electric motor, the gear rotates and meshes with the gear ring, causing the gear ring to drive the guide tube to rotate on the recycled and virgin dual-material drying cylinder. At the same time, the guide tube drives the first spiral plate to rotate synchronously, which facilitates the downward conveying of raw materials and increases the drying time of the raw materials.

[0014] Specifically, the second electric motor is connected to the control panel, and the second electric motor is regulated by a preset program in the control panel. A sealed bearing is fixedly sleeved on one end of the guide tube, and the outer wall of the sealed bearing is fixedly connected to the heating end of the burner. The sealed bearing not only ensures the sealed connection between the guide tube and the burner, but also allows the guide tube to rotate.

[0015] Specifically, the feeding mechanism includes a feeding pipe, a circulation pipe, a screw rod, a round pipe, a motor, and a feed pipe. The feeding pipe is fixedly installed on one side of the recycled and virgin dual-material drying cylinder, and the circulation pipe is sealed to one side of the feeding pipe. One end of the circulation pipe is sealed to the recycled and virgin dual-material drying cylinder. Through the cooperation of the circulation pipe, the feeding pipe, the screw rod, and the motor, the raw materials can be dried in a circulating manner according to the user's needs, thus improving flexibility.

[0016] Specifically, a screw rod is rotatably connected inside the feeding pipe, and a round pipe is sealed to the top of the feeding pipe. One end of the round pipe is sealed to the top of the recycled and virgin dual-material drying cylinder. A motor is fixedly installed at the top of the feeding pipe, and the output end of the motor is fixedly connected to one end of the screw rod. A feed pipe is sealed to one side of the feeding pipe. The raw materials to be dried are transported into the feeding pipe through the feed pipe, and the screw rod rotates under the drive of the motor. At the same time, the screw rod and the feeding pipe work together to transport the raw materials upward and through the round pipe into the recycled and virgin dual-material drying cylinder, thereby achieving the effect of automatic feeding.

[0017] Specifically, the recycled and virgin dual-material drying cylinder is equipped with a guide plate, which corresponds to the circulation pipe and serves to guide the material. The top of the recycled and virgin dual-material drying cylinder is sealed with a discharge pipe for discharging the dried raw materials.

[0030] The drying mechanism includes a burner 4, a guide tube 5, a spiral plate 6, a temperature sensor 7, and a motor 14.

One end of the guide tube 5 is rotatably connected to the heating end of the burner 4. A spiral plate 6 is fixedly installed on the guide tube 5. Through the coordinated design between the recycled and virgin dual-material drying cylinder 2, the drying mechanism, the feeding mechanism, and the control panel 15, the flame distance of the burner 4 can be extended and the time for the flame to act on the raw material can be increased, thereby greatly improving the drying effect and product quality. Moreover, through the coordinated action of the circulation pipe 9, the feeding pipe 8, the spiral rod 10, and the motor 12, the raw material can be dried in a circulating manner according to the user's needs, improving flexibility.

[0031] In this method, the spiral plate 6 is adapted to the recycled and virgin dual-material drying cylinder 2. A temperature sensor 7 is fixedly installed at one end of the guide tube 5.

The control panel 15 analyzes and judges the information and adjusts the power of the burner 4, thereby achieving the effect of regulating the temperature inside the recycled and virgin dual-material drying cylinder 2; thus further improving product quality.

[0032] In this method, the guide tube 5 is provided with multiple heat transfer holes, which correspond to the gaps of the spiral plate 6 to facilitate the heating and drying of the raw materials. The guide tube 5 is used to heat and dry the raw materials in the gaps of the spiral plate 6. Protective nets are fixedly installed in the multiple heat transfer holes. The effect of the multiple protective nets can prevent the raw materials from entering the guide tube 5.

[0033] In this method, a second motor 14 is fixedly installed on the bracket 3. A gear is fixedly connected to the output end of the second motor 14. A gear ring is meshed on the gear. The gear ring is fixedly sleeved on the guide tube 5. Driven by the second motor 14, the gear rotates and meshes with the gear ring, causing the gear ring to drive the guide tube 5 to rotate on the recycled and virgin dual-material drying cylinder 2. At the same time, the guide tube 5 drives the spiral plate 6 to rotate synchronously, which facilitates the downward conveying of raw materials and can increase the drying time of raw materials.

[0034] In this method, the second motor 14 is connected to the control panel 15. The second motor 14 is regulated by the preset program in the control panel 15. One end of the guide tube 5 is fixedly fitted with a sealing bearing 1. The outer wall of the sealing bearing 1 is fixedly connected to the heating end of the burner 4. The sealing bearing 1 not only ensures the sealed connection between the guide tube 5 and the burner 4, but also allows the guide tube 5 to rotate. The burner 4 is a conventional measure in this technical field and is clear and achievable by those skilled in the art. The burner 4 is the Zhongtong Thermal Energy ZCB series, which is existing technology and will not be described in detail.

[0035] In this method, the feeding mechanism includes a feeding pipe 8, a circulation pipe 9, a screw rod 10, a round pipe 11, a motor 12, and a feed pipe 13. The feeding pipe 8 is fixedly installed on one side of the recycled and virgin dual-material drying cylinder 2, and the circulation pipe 9 is sealed to one side of the feeding pipe 8. One end of the circulation pipe 9 is sealed to the recycled and virgin dual-material drying cylinder 2. Through the cooperation between the circulation pipe 9, the feeding pipe 8, the screw rod 10, and the motor 12, the raw materials can be dried in a circulating manner according to the user's needs, thus improving flexibility.

[0036] In this method, a screw rod 10 is rotatably connected inside the feeding pipe 8. A round pipe 11 is sealed to the top of the feeding pipe 8, and one end of the round pipe 11 is sealed to the top of the recycled and virgin dual-material drying cylinder 2. A motor 12 is fixedly installed on the top of the feeding pipe 8, and the output end of the motor 12 is fixedly connected to one end of the screw rod 10. A feed pipe 13 is sealed to one side of the feeding pipe 8. The raw materials to be dried are transported into the feeding pipe 8 through the feed pipe 13, and the screw rod 10 is rotated under the drive of the motor 12. At the same time, the screw rod 10 and the feeding pipe 8 work together to transport the raw materials upward and through the round pipe 11 to the recycled and virgin dual-material drying cylinder 2, thereby achieving the effect of automatic feeding.

[0037] In this method, the recycled and virgin dual-material drying cylinder 2 is equipped with a guide plate, which corresponds to the circulation pipe 9 and plays the role of guiding the material. The top of the recycled and virgin dual-material drying cylinder 2 is sealed with a discharge pipe 16, which is used to discharge the dried raw materials. Solenoid valves are installed on the discharge pipe 16, the feed pipe 13 and the circulation pipe 9. All three solenoid valves are connected to the control panel 15. The three solenoid valves are controlled by the preset program in the control panel 15, thereby controlling the opening and closing of the feed pipe 13, the discharge pipe 16 and the circulation pipe 9.

[0038] Working principle: When in use, first connect the power supply and adjust the motor 12, motor 2 14 and burner 4 through the preset program in the control panel 15;

[0039] First, the raw materials to be dried are transported to the feeding pipe 8 through the feeding pipe 13, and the screw rod 10 is rotated under the drive of the motor 12. At the same time, the screw rod 10 and the feeding pipe 8 work together to transport the raw materials upward and through the round pipe 11 to the recycled and original dual material drying cylinder 2, thereby achieving the effect of automatic feeding.

[0040] Then, the burner 4 drives its heating end to spray high-temperature flames into the guide tube 5. At the same time, the guide tube 5 increases the length of the sprayed flame and the heating time of the raw material, thereby improving the drying effect and product quality.

[0041] Meanwhile, the gear is driven by the electric motor 14 to rotate and mesh with the gear ring, which drives the guide tube 5 to rotate on the recycled virgin double material drying cylinder 2. At the same time, the guide tube 5 drives the spiral plate 6 to rotate synchronously. Through the cooperation between the spiral plate 6 and the recycled virgin double material drying cylinder 2, the raw material is conveyed downward in a spiral manner in the recycled virgin double material drying cylinder 2, thereby further increasing the drying time of the raw material.

[0042] Meanwhile, the temperature sensor 7 can monitor the temperature inside the recycled and virgin dual-material drying cylinder 2 and transmit the monitored information to the control panel 15. The control panel 15 analyzes and judges the information and adjusts the power of the burner 4, thereby achieving the effect of regulating the temperature inside the recycled and virgin dual-material drying cylinder 2; thus further improving product quality.

[0043] Through the function of the circulation pipe 9 and the drive of the motor 12 to the screw 10, the raw materials can be dried in a circulating manner according to the user's needs, thus improving flexibility.

[0044] Finally, the dried raw materials are discharged through the discharge pipe 16.

[0045] The technological advancements of this invention compared to existing technologies are as follows: the coordination of various components can increase the drying time of raw materials, thereby greatly improving the drying effect and product quality. It can also achieve a cyclic drying effect for raw materials according to user needs, enhancing flexibility. Moreover, the structure is simple and more practical.
