Description

Technical Field

[0001] This invention relates to the field of emulsified asphalt production equipment technology, and in particular to an environmentally friendly device for producing high-viscosity modified emulsified asphalt. Background Technology

[0002] High-viscosity modified emulsified asphalt is an emulsified asphalt product whose performance is improved by adding modifiers. It has high viscosity and good performance characteristics. High-viscosity modified emulsified asphalt incorporates high molecular weight polymers, which can significantly increase the viscosity of the asphalt, thereby improving its performance. During the production of high-viscosity modified emulsified asphalt, the asphalt needs to be heated to a suitable temperature to achieve good fluidity. When the asphalt is heated in the heating tank, asphalt fumes are generated. The existing method of handling this is to install an activated carbon filter on the heating tank to filter the asphalt fumes. However, the activated carbon particles in the filter on the heating tank tend to accumulate and not circulate. The activated carbon particles can only adsorb the asphalt fumes they come into contact with, reducing the utilization rate of the activated carbon particles and resulting in poor long-term adsorption effect, which is a drawback.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1 to 8An environmentally friendly device for producing high-viscosity modified emulsified asphalt includes a heating tank 10, an air inlet pipe 2, a filter box 3, and an exhaust pipe 4. The air inlet pipe 2 connects the heating tank 10 and the filter box 3. The filter box 3 is equipped with the exhaust pipe 4. The wall of the filter box 3 is provided with an inlet 301, a spiral groove 302, a first outlet 303, a second outlet 304, and two mesh openings 305. The spiral groove 302 communicates with the inlet 301 and the first outlet 303, respectively. The device also includes:

[0028] The adjustment device includes a piston rod 5 and a first driving device. One end of the piston rod 5 can slide inside the filter box 3, and the other end extends out of the filter box 3. One end face of the piston rod 5 is inclined and has an inclined groove 501. The first driving device is used to drive the piston rod 5 to move up and down inside the filter box 3.

[0029] The discharge device includes a discharge cylinder 6, an arc plate 7, a limiting rod 8, and a second driving device. The arc plate 7 is disposed inside the discharge cylinder 6, and the limiting rod 8 is disposed inside the filter box 3, one end of which cooperates with the insertion hole on the discharge cylinder 6. The second driving device is used to drive the piston rod 5 to rotate relative to the discharge cylinder 6.

[0030] The feeding device is used to indirectly supply unused activated carbon to the filter box 3;

[0031] A material receiving device is installed at the bottom of the filter box 3;

[0032] The system includes three time relays, a counting sensor 9, and a controller. The first drive device, the second drive device, the three time relays, and the counting sensor 9 are electrically connected to the controller. In this invention, the activated carbon particles in the filter box 3 cover the top of the mesh 305 by a certain distance. During the heating process of the asphalt in the heating tank 10, the first time relay operates. The asphalt fumes generated by the heating tank 10 flow from the exhaust pipe 2 into the filter box 3, are filtered by the internal activated carbon, and are discharged from the exhaust pipe 4. When the first time relay reaches a preset value, it sends a signal to the controller. The controller controls the first drive device and the second time relay to operate. The first drive device drives the piston rod 5 to move upward, causing the activated agent to move upward. During the upward movement of the piston rod 5, the discharge cylinder 6 blocks the first discharge port 303 and the two meshes 305. The activated agent falls from the inlet 301 into the spiral groove 302. The first drive device drives the piston rod 5 to move downward back to its original position. The activated carbon particles flow out from the first discharge port 303 and fall onto the piston rod 5, thereby changing the position of the activated carbon particles in the filter box 3. For better filtration of asphalt fumes, when the second time relay reaches a preset value, it sends a signal to the controller. The controller then controls the first time relay to restart, repeating the above operation. This intermittently changes the position of activated carbon particles in the filter box 3. Each time the piston rod 5 moves upward, the counting sensor 9 counts the particles. When the preset value of the counting sensor 9 is reached, it sends a signal to the controller. The controller then controls the second drive device and the third time relay. The second drive device drives the piston rod 5 to rotate, moving the inclined groove 501 away from the arc plate 7. The activated carbon particles on the piston rod 5 flow from the inclined groove 501 into the discharge cylinder 6 and finally fall into the receiving device. Simultaneously, the feeding device delivers a certain amount of unused activated carbon particles into the filter box 3, covering the top of the mesh 305. When the third time relay reaches a preset value, it sends a signal to the controller, which then controls the counting sensor 9 to restart the counting. Specifically, the heating tank 10 is existing technology and will not be described further; the height of one end of the spiral groove 302 is greater than that of the other end.

[0033] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0034] In this embodiment, the piston rod 5 has a T-shaped first connecting rod 502 at its bottom, and the discharge cylinder 6 has a first sliding groove 601 that is adapted to the first connecting rod 502. When the second driving device drives the piston rod 5 to rotate, the first connecting rod 502 rotates in the first sliding groove 601. The limiting rod 8 cooperates with the insertion hole at the bottom of the discharge cylinder 6, so that the rotation of the piston rod 5 can limit the rotation of the discharge cylinder 6.

[0035] In this embodiment, the first driving device includes a support box 11, a motor 12, a first pull rope 13, and a wire roller 14. The support box 11 is mounted on the filter box 3, and the motor 12 is mounted on the support box 11 to drive the wire roller 14 to rotate. The first pull rope 13 connects the piston rod 5 and the wire roller 14. The motor 12 drives the wire roller 14 to rotate in both directions, thereby winding or unwinding the first pull rope 13, causing the piston rod 5 to move upward or downward. Specifically, three time relays, a counting sensor 9, and a controller are all housed within the support box 11; the lead screw mechanism 15 is also housed within the support box 11.

[0036] In this embodiment, the second driving device includes a lead screw mechanism 15, a toothed plate 16, and a gear 17. The lead screw mechanism 15 is mounted on the filter box 3 to drive the toothed plate 16 to move back and forth. The gear 17 is mounted on the piston rod 5 and meshes with the toothed plate 16. The controller controls the lead screw mechanism 15 to operate, causing the toothed plate 16 to move back and forth, driving the gear 17 to rotate forward and backward, thereby causing the piston rod 5 to rotate forward and backward. Specifically, the lead screw mechanism 15 is prior art and will not be described further here.

[0037] In this embodiment, the filter box 3 is provided with a second sliding groove 306 communicating with the spiral groove 302; the feeding device includes a feeding box 18, a feeding pipe 19, a baffle plate 20, a second pull rope 21, and an alarm device. The feeding pipe 19 is provided at the bottom of the feeding box 18, and one end of the feeding pipe 19 extends into the spiral groove 302. The baffle plate 20 can slide within the spiral groove 302 and the second sliding groove 306. The second pull rope 21 connects the second driving device and the baffle plate 20. When there are no activated carbon particles in the feeding pipe 19, the alarm device sounds an alarm. When replacing with new activated carbon particles, the first driving device drives the piston rod 5 to move upward, and the activated carbon particles on the piston rod 5 fall into the spiral groove 302. The first driving device then drives the piston rod 5 to move downward. The activated carbon particles in the spiral groove 302 fall onto the piston rod 5. At this time, the screw mechanism 15 drives the toothed plate 16 to move to the left, causing the piston rod 5 to rotate. The inclined groove 501 is on the other side of the arc plate 7. The activated carbon particles in the piston rod 5 are discharged from the inclined groove 501 into the discharge cylinder 6. As the toothed plate 16 moves to the left, the baffle plate 20 moves downward and does not block the feed pipe 19. Some of the activated carbon particles in the feed pipe 19 fall into the spiral groove 302. When the activated carbon particles roll to the other end of the spiral groove 302, the screw mechanism 15 drives the toothed plate 16 to move to the right, causing the piston rod 5 to rotate in the opposite direction. The inclined groove 501 is on one side of the arc plate 7, and the activated carbon particles will not be discharged from the inclined groove 501. The unadsorbed activated carbon particles in the spiral groove 302 fall onto the piston rod 5 and cover the top of the mesh 305, realizing the replacement of the activated carbon particles in the discharge cylinder 6. Specifically, the amount of activated carbon particles discharged from the feed pipe 19 falls onto the piston rod 5 and covers the top of the mesh 305; the feed box 18 is equipped with a cover plate, which is detachably connected to the feed box 18 by bolts; the filter box 3 and the feed box 18 are fixed to the ground by external fasteners, such as several support feet.

[0038] In this embodiment, the baffle plate 20 is provided with a groove 201; the alarm device includes a connecting plate 22, a T-shaped second connecting rod 23, a metal block 24, a spring 25, two conductive blocks 26, and an alarm. The connecting plate 22 is provided with a third sliding groove 221. One end of the second connecting rod 23 can slide in the third sliding groove 221, and the other end is connected to the baffle plate 20. The spring 25 is sleeved on the second connecting rod 23. The metal block 24 is disposed on the second connecting rod 23. The conductive blocks 26 are disposed on the connecting plate 22. Activated carbon particles in the feed pipe 19 fall into the groove 201, making the baffle plate 20 heavier. One end of the connecting rod 23 moves downward within the third sliding groove 221 and compresses the spring 25. When there are no activated carbon particles in the feeding pipe 19, the activated carbon particles in the groove 201 fall into the feeding pipe 19, making the baffle plate 20 lighter. The spring 25 exerts a reaction force on the second connecting rod 23, causing it to return to its original position. The metal block 24 contacts the two conductive blocks 26, activating the alarm circuit and triggering an alarm. The staff, knowing there are no activated carbon particles in the feeding pipe 19, add activated carbon particles to the feeding box 18. Since the falling activated carbon particles will produce carbon powder, electronic monitoring equipment such as sensors are easily interfered with and damaged by the carbon powder. This structure, used to monitor whether there are activated carbon particles in the feeding pipe 19, is less prone to damage. Specifically, the bottom wall of the groove 201 is sloped; the alarm is an electric bell or warning light, installed in the office or on the heating tank 10.

[0039] In this embodiment, the receiving device includes a flexible hose 27 and a collection box. The flexible hose 27 connects the discharge cylinder 6 and the collection box, and the activated carbon particles in the discharge cylinder 6 fall into the collection box through the flexible hose 27. Specifically, one end of the flexible hose 27 passes through the second discharge port 304 and is connected to the discharge cylinder 6.
