Description

Technical Field

[0001] This application relates to the field of aggregate processing, and in particular to a cold aggregate drying cylinder. Background Technology

[0002] Asphalt mixtures are composite materials, mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder, and sometimes polymers and wood cellulose are added. These materials, in varying quantities and qualities, form different structures and possess different mechanical properties. Before mixing asphalt, the aggregates in the mixture need to be dried using a drying device.

[0003] A Chinese patent with publication number CN205228078U discloses a drying cylinder, including a cylinder body with two gear rings connected to a motor. The cylinder body is mounted on a frame, which includes a support frame. A cylinder frame is mounted on the support frame, and the cylinder frame includes an outer ring and an inner ring. The outer ring is fixed to the support frame, and the inner ring is fixed to the outer wall of the cylinder body. A ball bearing is provided between the outer ring and the inner ring. The outer ring, the ball bearing, and the inner ring are fixed together by a retainer. The two cylinder frames and the support frame support the cylinder body. A reinforcing ring made of high-strength steel is also provided between the cylinder body and the inner ring, and a shock-absorbing ring is wrapped around the reinforcing ring.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: during the actual drying process, cold aggregates accumulate and clump together, resulting in uneven heating inside the aggregates, which causes some aggregates to dry more slowly and require a longer time, thereby reducing the drying efficiency. Therefore, a cold aggregate drying cylinder is now proposed. Utility Model Content

[0005] To address the problem of uneven heating within the aggregate, which reduces drying efficiency, this application provides a cold aggregate drying cylinder.

[0006] The cold aggregate drying cylinder provided in this application adopts the following technical solution:

[0007] A cold aggregate drying cylinder includes a cylinder body, a heat-conducting component, and a driving component. An isolation cover is fixedly fitted on the outer circumference of the cylinder body. The heat-conducting component includes an air inlet pipe and a spiral air guide pipe and a transverse air guide pipe connected to the air inlet pipe. The spiral air guide pipe is spirally arranged inside the isolation cover. The transverse air guide pipe is rotatably installed inside the cylinder body. Multiple sets of longitudinal air guide pipes are fixedly connected to the surface of the transverse air guide pipe. The surface of the longitudinal air guide pipe is provided with several air outlet holes. The driving component is used to drive the transverse air guide pipe to rotate.

[0008] By adopting the above technical solution, and through the setting of the heat-conducting components, hot air can be delivered to the spiral air guide pipe and the transverse air guide pipe respectively through the air inlet pipe. The spiral air guide pipe heats the side wall of the cylinder, causing the aggregate close to the side wall of the cylinder to be heated and dried. The transverse air guide pipe introduces hot air into the inside of the cylinder and discharges it directly into the aggregate through the air outlet of the longitudinal air guide pipe, which can directly heat the inside of the aggregate, thereby making the aggregate heated evenly. During drying, the drive component can drive the transverse air guide pipe to rotate, thereby causing the longitudinal air guide pipe to stir the piled aggregate, further increasing the heating area of ​​the aggregate and improving the drying efficiency.

[0009] Preferably, a feed pipe is fixedly connected to the top of one end of the cylinder.

[0010] By adopting the above technical solution, cold aggregate can be added into the cylinder through the feed pipe.

[0011] Preferably, a rotary joint is provided between the transverse air guide pipe and the air intake pipe, and the transverse air guide pipe and the air intake pipe are rotatably connected through the rotary joint.

[0012] By adopting the above technical solution and setting a rotary joint, the transverse air guide pipe and the air intake pipe can rotate relative to each other.

[0013] Preferably, a filter screen is fixedly connected to the outlet of the air outlet.

[0014] By adopting the above technical solution and setting up a filter screen, cold aggregate can be filtered and intercepted, preventing it from entering the air outlet.

[0015] Preferably, the drive assembly includes a motor, a main gear, and a driven gear. The main gear is fixedly mounted on the output shaft of the motor, and the driven gear is fixedly mounted on the transverse air guide pipe and meshes with the main gear.

[0016] By adopting the above technical solution, the motor can be started to drive the main gear to rotate, which in turn drives the driven gear to rotate, and the driven gear drives the transverse air guide pipe to rotate.

[0017] Preferably, a cover is fixedly installed at one end of the cylinder near the feed pipe, the motor is fixedly installed on the outer wall of the cover, and the main gear and the driven gear are located inside the cover.

[0018] By adopting the above technical solution and setting up a cover, the main gear and the driven gear can be protected.

[0019] Preferably, the end of the cylinder away from the feed pipe has a discharge port, a baffle is hinged at the discharge port, and a pin is inserted into the outer wall of the baffle.

[0020] By adopting the above technical solution, after drying, the pin can be pulled out to open the baffle and allow the aggregate to be discharged from the outlet.

[0021] Preferably, a base is provided at the bottom of the cylinder, a bracket is fixedly installed at one end of the base near the discharge port, the cylinder is hinged to the bracket, and an electric push rod is hinged at the end of the base away from the discharge port, with the upper end of the electric push rod hinged to the cylinder.

[0022] By adopting the above technical solution, during material discharge, the electric push rod can be activated to lift the end of the cylinder away from the discharge port, causing the end of the cylinder facing the discharge port to tilt downwards, thereby facilitating the discharge of aggregate from the discharge port.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Using heat-conducting components, hot air can be delivered to the spiral air guide pipe and the transverse air guide pipe through the air inlet pipe. The spiral air guide pipe heats the side wall of the cylinder, causing the aggregate close to the side wall of the cylinder to be heated and dried. The transverse air guide pipe introduces hot air into the inside of the cylinder and discharges it directly into the aggregate through the air outlet of the longitudinal air guide pipe, which can directly heat the inside of the aggregate, thereby making the aggregate heated evenly and improving the drying efficiency.

[0025] 2. With the help of the drive assembly, during drying, the motor can be started to drive the main gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the transverse air guide pipe to rotate. This allows the longitudinal air guide pipe to stir the piled aggregate, further increasing the heated area of ​​the aggregate and improving the drying efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a cold aggregate drying cylinder.

[0033] Reference Figure 1 and Figure 2 A cold aggregate drying cylinder includes a cylinder body 1, a heat-conducting component 2, and a driving component 3. A feed pipe 12 is fixedly connected to the top of one end of the cylinder body 1, through which cold aggregate is added to the cylinder body 1. An isolation cover 11 is fixedly fitted onto the outer circumference of the cylinder body 1. The heat-conducting component 2 includes an air inlet pipe 21 and a spiral air guide pipe 22 and a transverse air guide pipe 23 connected to the air inlet pipe 21. The inlet of the air inlet pipe 21 is connected to a hot air source. The spiral air guide pipe 22 is spirally arranged inside the isolation cover 11. The transverse air guide pipe 23 is rotatably installed inside the cylinder body 1. Multiple sets of longitudinal air guide pipes 24 are fixedly connected to the surface of the transverse air guide pipe 23, and several air outlet holes 25 are provided on the surface of the longitudinal air guide pipes 24. With the heat-conducting component 2, hot air can be delivered to the spiral air guide pipe 22 and the transverse air guide pipe 23 through the air inlet pipe 21, so that the spiral air guide pipe 22 heats the side wall of the cylinder 1, and the aggregate close to the side wall of the cylinder 1 is heated and dried. The transverse air guide pipe 23 introduces the hot air into the inside of the cylinder 1 and discharges it directly into the inside of the aggregate through the air outlet 25 of the longitudinal air guide pipe 24, which can directly heat the inside of the aggregate, so that the aggregate is heated evenly and the drying efficiency is improved.

[0034] Among them, reference Figure 3 A filter screen 27 is fixedly connected to the outlet of the air outlet 25. By setting the filter screen 27, cold aggregate can be filtered and intercepted to prevent cold aggregate from entering the air outlet 25.

[0035] Reference Figure 1 and Figure 2The drive assembly 3 is used to drive the transverse air guide pipe 23 to rotate. The drive assembly 3 includes a motor 31, a main gear 32, and a driven gear 33. The main gear 32 is fixedly mounted on the output shaft of the motor 31, and the driven gear 33 is fixedly mounted on the transverse air guide pipe 23 and meshes with the main gear 32. By setting the drive assembly 3, during drying, the motor 31 can be started to drive the main gear 32 to rotate, which in turn drives the driven gear 33 to rotate, which in turn drives the transverse air guide pipe 23 to rotate. This allows the longitudinal air guide pipe 24 to stir the accumulated aggregate, further increasing the heating area of ​​the aggregate and improving the drying efficiency. A cover 13 is fixedly installed at one end of the cylinder 1 near the feed pipe 12. The motor 31 is fixedly mounted on the outer wall of the cover 13. The main gear 32 and the driven gear 33 are located inside the cover 13. By setting the cover 13, the main gear 32 and the driven gear 33 can be protected.

[0036] A rotary joint 26 is provided between the transverse air guide pipe 23 and the air intake pipe 21. The transverse air guide pipe 23 and the air intake pipe 21 are rotatably connected through the rotary joint 26. By providing the rotary joint 26, the transverse air guide pipe 23 and the air intake pipe 21 can rotate relative to each other.

[0037] Reference Figure 2 and Figure 3 The cylinder 1 has a discharge port at the end away from the feed pipe 12. A baffle 14 is hinged at the discharge port. A pin 15 is inserted into the outer wall of the baffle 14. After drying, the pin 15 can be pulled out to open the baffle 14 and allow the aggregate to be discharged from the discharge port.

[0038] To facilitate material discharge, a base 4 is provided at the bottom of the cylinder 1. A bracket 41 is fixedly installed at the end of the base 4 near the discharge port. The cylinder 1 is hinged to the bracket 41. An electric push rod 42 is hinged to the end of the base 4 away from the discharge port. The upper end of the electric push rod 42 is hinged to the cylinder 1. During material discharge, the electric push rod 42 can be activated to lift the end of the cylinder 1 away from the discharge port, so that the end of the cylinder 1 facing the discharge port tilts downward, thereby facilitating the discharge of aggregate from the discharge port.

[0039] The implementation principle of this application is as follows: Cold aggregate can be added into the cylinder 1 through the feed pipe 12, and hot air can be delivered to the spiral air guide pipe 22 and the transverse air guide pipe 23 through the air inlet pipe 21. The spiral air guide pipe 22 heats the side wall of the cylinder 1, so that the aggregate close to the side wall of the cylinder 1 is heated and dried. The transverse air guide pipe 23 introduces the hot air into the inside of the cylinder 1 and discharges it directly into the inside of the aggregate through the air outlet 25 of the longitudinal air guide pipe 24. This can directly heat the inside of the aggregate, so that the aggregate is heated evenly and the drying efficiency is improved. During drying, the motor 31 can be started to drive the main gear 32 to rotate, which drives the driven gear 33 to rotate, which drives the transverse air guide pipe 23 to rotate. This allows the longitudinal air guide pipe 24 to stir the piled aggregate, further increasing the heating area of ​​the aggregate and improving the drying efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
