Description

Technical Field

[0001] The invention relates to the technical field of rubber asphalt production equipment, in particular to a rubber powder combined activation device. Background Art

[0002] Activated rubber powder has shown broad application potential in the fields of modified asphalt due to its excellent adhesion and high reactivity. In the preparation of modified asphalt, activated rubber powder as an additive can significantly improve the heat resistance, anti-aging ability and adhesion of asphalt. Twin-screw extrusion activation technology is the key equipment to achieve rubber powder activation modification, but it has problems such as single method and low efficiency when activating rubber powder. At the same time, when the twin-screw extrusion equipment is running, in order to ensure the uniformity of the discharge, a stable feeding rate must be maintained. However, the existing feeding device often cannot achieve balanced and stable feeding when responding to pressure changes, which leads to frequent problems of breakage and uneven discharge. In addition, the currently commonly used spiral conveying method for feeding, although easy to operate, has difficulties in adjusting the feeding speed. Once the feeding speed is too fast, the internal pressure rises sharply, which can easily lead to overload of the feeding motor, thereby shortening its service life. For this reason, we propose a rubber powder combined activation equipment. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a rubber powder combined activation device, comprising a twin-screw extruder 1, a guide pipe 11, and a discharge pipe 12 and a feed pipe 13 arranged on the guide pipe 11, the discharge pipe 12 is connected to the twin-screw extruder 1, and also includes: A shaft 2 is rotatably mounted on the material guide tube 11 and one end of the shaft 2 is located inside the material guide tube 11 and is fixedly connected to a spiral feeding blade 3; A driving assembly 4 is arranged on the twin-screw extruder 1 and connected to the shaft 1 2, and is used to drive the shaft 1 2 and the spiral feeding blade 3 to rotate and feed; The piston plate 5 is slidably disposed in the material guide tube 11; The linkage assembly 6 is arranged on the guide tube 11, and the piston plate 5 is connected to the shaft 2 through the linkage assembly 6. When the pressure in the guide tube 11 increases, the linkage assembly 6 is connected to the shaft 2 and drives the piston plate 5 to move to increase the inner cavity of the guide tube 11; A microwave generator 7 is provided on the twin-screw extruder 1 and is used for microwave activation of the rubber powder; During specific use, when the pressure in the material guide tube 11 is greater than a certain value, the piston plate 5 will be pushed to move relative to the slide plate 45, thereby driving the linkage component 6 to connect with the shaft 2, and then the piston plate 5 is driven to move through the rotation of the shaft 2 to increase the inner cavity of the material guide tube 11, and then the pressure in the material guide tube 11 is automatically reduced in time to protect the drive motor 44, while also ensuring that the feeding pressure is stable. However, when the piston plate 5 continues to move for a distance, the pressure in the material guide tube 11 is still increasing. At this time, the delayed transmission component 81 is used to drive the gear disc six 77 to engage with the gear disc four 53, thereby greatly reducing the rotation speed of the shaft 2, thereby further reducing the pressure in the material guide tube 11. At the same time, the device integrates the dual activation technology of twin-screw extrusion and microwave irradiation, aiming to further optimize the activation effect of the rubber powder through the synergistic effect of these two methods.

A transmission member 52 is provided between the toothed disc 3 51 and the threaded sleeve 48. The toothed disc 3 51 is rotated to drive the threaded sleeve 48 to rotate by the transmission member 52. A toothed disc four 53 is fixedly connected to the shaft one 2, and a linkage member 54 is provided between the movable plate 49 and the piston plate 5. When the pressure in the guide tube 11 increases to push the piston plate 5 to move relative to the slide plate 45, the linkage member 54 is utilized to drive the movable plate 49 and the toothed disc three 51 to move so as to drive the toothed disc three 51 to engage with the toothed disc four 53.

[0021] The transmission member 52 includes a shaft 55 rotatably connected to the guide tube 11 through a bearing, a synchronous pulley 56 is fixedly connected to one end of the shaft 55, and a synchronous pulley 56 is also fixedly connected to the threaded sleeve 48. The two synchronous pulleys 56 are connected by a synchronous belt. When the shaft 55 is rotated, the synchronous pulley 56 cooperates with the synchronous belt to drive the threaded sleeve 48 to rotate; A hollow shaft four 57 is rotatably connected to the movable plate 49 through a bearing, and a gear plate three 51 is also fixedly connected to the hollow shaft four 57. The two gear plates three 51 are meshed, and one end of the shaft three 55 passes through the hollow shaft four 57. A sliding protrusion 58 is fixedly connected inside the hollow shaft four 57. A sliding groove 59 is provided on the shaft three 55. One end of the sliding protrusion 58 is located in the sliding groove 59 to guide and limit the sliding of the hollow shaft four 57. The sliding protrusion 58 is slidably connected to the inner wall of the sliding groove 59.

[0022] The linkage member 54 includes an injection cylinder 61 fixedly connected to the guide tube 11, a piston 62 is slidably connected in the injection cylinder 61, a push rod 63 is fixedly connected between the piston 62 and the movable plate 49, and the injection cylinder 61 is filled with hydraulic oil. The hydraulic oil is filled into the injection cylinder 61 to push the piston 62 to move, thereby pushing the push plate 82 to move, and further pushing the movable plate 49 to move; A syringe 2 64 is fixedly connected to the slide plate 45, a piston 2 65 is slidably connected inside the syringe 2 64, a push rod 2 66 is fixedly connected between the piston 2 65 and the piston plate 5, and the syringe 2 64 is also filled with hydraulic oil. A hard guide tube 67 is conductively connected to one end of the syringe 2 64, and one end of the hard guide tube 67 slides through the guide tube 11 and is conductively connected to the syringe 1 61 through the guide tube. A pressure spring 68 is fixedly connected between the piston plate 5 and the slide plate 45. When the pressure in the guide tube 11 increases, the piston plate 5 is pushed to move to drive the piston 2 65 to move, thereby pushing the hydraulic oil into the syringe 1 61, and at the same time compressing the pressure spring 68 to provide it with self-restoring elastic force.

[0023] The inner wall of the guide tube 11 is fixedly connected with an arc-shaped protrusion 69 for blocking the piston plate 5, and one end of the hollow shaft 4 57 is fixedly connected with a toothed disc 5 71. When the pressure in the guide tube 11 decreases, the pressure spring 68 resets and drives the piston 2 65 to move to extract the hydraulic oil in the syringe 1 61, driving the toothed disc 5 71 to engage with the toothed disc 4 53; Specifically, in the initial state of the device, the pressure spring 68 is already in a semi-compressed state. At this time, the toothed disc three 51 and the toothed disc five 71 on the moving plate 49 are not engaged with the toothed disc four 53. Therefore, when the shaft one 2 rotates to drive the spiral feeding blade 3 to rotate and feed, if the feeding pressure is normal or the pressure is less than the force of the pressure spring 68 to continue to compress, the piston plate 5 will not be triggered to move. When the pressure in the guide tube 11 increases, the piston plate 5 will be pushed to move relative to the slide plate 45 and compress the pressure spring 68, and at the same time, the piston two 65 will be pushed to move, and then the hydraulic oil will be filled into the injection cylinder one 61 and the piston one 62 will be pushed to move, and then the push rod one 63 and the moving plate 49 will be driven to move, and then the toothed disc three 51 and the toothed disc four 53 will be driven to mesh, and then the toothed disc three 51, the hollow shaft four 57, the shaft three 55, the synchronous pulley 56, and the threaded sleeve 48 will be driven to rotate, and then the screw 47, the slide plate 45 and the piston plate 5 will be driven to move, so as to increase the inner cavity of the guide tube 11, and then the pressure in the guide tube 11 will be reduced in time. When the pressure in the guide tube 11 continues to increase to push the piston plate 5 to move continuously, the slide rod 46 drives the Y-shaped frame 78 to move at the same time, so as to drive a push plate 82 on the guide rod 2 79 to push the spring 1 83 between a limit plate 84 on the guide rod 1 72 and compress it. When the piston plate 5 moves to a certain distance, the spring 1 83 is also compressed to a certain extent. At this time, the elastic force accumulated in the spring 1 83 breaks through the suction force between the magnet 86 and the iron plate 87, and then pushes the guide rod 1 72, thereby driving the L-shaped plate 73 to move, and then driving the toothed disc 6 77 to engage with the toothed disc 4 53, and at the same time, the toothed disc 1 41 is disengaged from the toothed disc 2 43, thereby greatly reducing the rotation speed of the shaft 1 2 and the spiral feeding blade 3, and at the same time reducing the operating load of the drive motor 44.

[0024] One end of the guide tube 11 is slidably connected to a guide rod 1 72, one end of the guide rod 1 72 is fixedly connected to an L-shaped plate 73, a hollow shaft 6 74 is rotatably connected to the L-shaped plate 73 through a bearing, the hollow shaft 6 74 is fixedly connected to the gear plate 2 43, and the shaft 2 42 passes through the hollow shaft 6 74, the inner wall of the hollow shaft 6 74 is fixedly connected to a sliding protrusion 2 75, the shaft 2 42 is provided with a sliding groove 2 76, one end of the sliding protrusion 2 75 is located in the sliding groove 2 76 to guide and limit the sliding of the hollow shaft 6 74, and the sliding protrusion 2 75 is slidably connected to the inner wall of the sliding groove 2 76; A toothed disc six 77 is fixedly connected to the hollow shaft six 74. The diameter of the toothed disc six 77 is designed to be smaller than that of the toothed disc four 53. The toothed disc six 77 is designed to be the same as the toothed disc one 41. The toothed disc two 43 is designed to be the same as the toothed disc four 53. A Y-shaped frame 78 is fixedly connected to one end of the slide rod 46. A guide rod two 79 is fixedly connected to one end of the Y-shaped frame 78. The guide rod two 79 is slidably connected to the guide pipe 11. A delay transmission component 81 is arranged between the guide rod two 79 and the guide rod one 72. After the slide rod 46 moves to drive the guide rod two 79 to move a certain distance, the delay transmission component 81 is used to drive the guide rod one 72 and the L-shaped plate 73 to move, so as to drive the toothed disc six 77 to engage with the toothed disc four 53.

[0025] The delay transmission assembly 81 includes two push plates 82 fixedly connected to the guide rod 79, and one end of the guide rod 72 slides through the two push plates 82, one side of the two push plates 82 is fixedly connected to a spring 83, two limit plates 84 are fixedly connected to the guide rod 72, and a mounting plate 85 is fixedly connected to the guide rod 72, a magnet 86 is fixedly connected to the mounting plate 85, and two iron plates 87 are fixedly connected to the guide tube 11.

[0026] Example 2: Please refer to Figure 1-Figure 8 , the present invention provides a technical solution: Example 2 is optimized on the basis of Example 1; An air guide pipe 88 is connected between the feed pipe 13 and the guide pipe 11 , and the movable piston plate 5 uses the air guide pipe 88 to fill gas into the feed pipe 13 .

[0027] The guide pipe 11 is connected to an air intake pipe 89, and both the guide pipe 88 and the air intake pipe 89 are provided with a one-way valve 91. The one-way valve 91 in the guide pipe 88 only allows gas to be discharged from the guide pipe 11, and the one-way valve 91 in the air intake pipe 89 only allows air to enter the guide pipe 11. During specific use, when the pressure in the material guide tube 11 increases, the piston plate 5 will move, thereby squeezing the gas in the material guide tube 11 from the air guide tube 88 into the feed tube 13, thereby filling a certain amount of gas into the rubber powder to reduce the density of the rubber powder entering the material guide tube 11, thereby further reducing the pressure in the material guide tube 11.
