Description

Technical Field

[0001] The present invention relates to the technical field of preheating devices, and more particularly to an asphalt storage tank with a preheating function. Background Art

[0002] In the production process of asphalt, the preheating device plays a vital role, aiming to prevent the instability of asphalt quality due to excessive temperature difference when the raw materials enter the mixing plant. Existing asphalt preheating devices mainly rely on the principles of heat conduction and heat convection, and effectively transfer heat to the asphalt raw materials through heat sources (such as steam, heat transfer oil, etc.), so that they gradually heat up. These devices are also equipped with advanced circulation systems and stirring devices to ensure that the asphalt raw materials can be heated evenly during the preheating process, thereby avoiding local overheating or overcooling.

[0003] However, although the existing asphalt preheating devices are technically quite mature, the design of their internal heating and mixing equipment is relatively complex, and usually requires external control equipment to fine-tune a series of operations such as mixing, heat dissipation, and temperature control. This complexity not only requires operators to have high professional knowledge and skills to ensure the normal operation and maintenance of the device, but also limits the level of automation of the asphalt preheating process. As a result, although the existing asphalt preheating devices meet production needs to a certain extent, they have high requirements for users and it is difficult to achieve a fully automated asphalt preheating effect.

[0023] A method for using an asphalt storage tank with a preheating function comprises the following steps:

[0024] S1. When in use, inject asphalt into the preheating tank, and when preheating the asphalt, drive the heater and the motor through the control panel;

[0025] S2. When preheating asphalt, the motor needs to be started to drive the driving pipe to rotate forward. At this time, the driving pipe will drive the deflector to rotate and adjust the angle of the deflector through the shift block, so that the deflector draws the upper air and discharges it downward, thereby extracting the gas in the heater and discharging it into the preheating tank simultaneously. The forward rotating driving shaft will drive the asphalt in the preheating tank to move upward through the first spiral blade to achieve preheating of the asphalt. When discharging the asphalt, the motor needs to be started to drive the driving pipe to rotate in the opposite direction. At this time, the driving pipe will drive the deflector to rotate and adjust the angle of the deflector through the shift block again, so that the deflector draws the upper air and discharges it downward, thereby extracting the gas in the heater and discharging it into the preheating tank simultaneously, achieving a continuous heating effect. At the same time, the reverse rotating docking head will drive the installation cylinder to rotate, so that the first spiral blade and the second spiral blade will discharge the asphalt downward synchronously, ensuring the heat of the asphalt while accelerating the discharge of the asphalt;

[0026] S2.1. When preheating asphalt, the motor needs to be started to drive the drive tube to rotate in the forward direction. At this time, the drive tube will drive the installation sleeve, the rotating rod and the fan blades to rotate. At this time, the fan blades will be squeezed by the shift block during the contact with the shift block and the angle will be tilted, so that when the fan blades rotate forward, they will extract the hot air in the heater and the gas in the connecting ring for discharge. When the gas enters the drive tube and the cleaning rod along the exhaust pipe, the cleaning rod will discharge the gas through the aeration port. Because there are only two aeration holes for exhaust when the drive tube drives the docking cover to rotate, the gas will accumulate in the sealing tube. When the aeration hole is connected to the docking cover, the gas will be compressed and discharged. At this time, a large amount of gas will be discharged along the cleaning rod to achieve the effect of automatic aeration.

[0027] S2.2. When discharging asphalt, the motor needs to be started to drive the driving tube to rotate in the opposite direction. At this time, the driving tube will drive the installation sleeve to rotate and adjust the angle of the fan blades accordingly through the shift block again, so that the fan blades will still draw air from above and discharge it downward when rotating in the opposite direction, and the reverse rotating drive shaft and elastic telescopic rod will drive the docking joint to be inserted into the docking groove, so that the vertical surface of the docking joint and the vertical surface of the docking groove are docked, thereby synchronously driving the installation cylinder and the second spiral blade to rotate. Since the first spiral blade in the reverse rotating state will push the asphalt downward, the asphalt will accumulate at the bottom of the preheating tank. As the installation cylinder rotates, the asphalt will be discharged along the discharge trough and the discharge pipe.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention designs a motor, a deflector, a first spiral blade and a second spiral blade. When preheating asphalt, the motor needs to be started to drive the driving pipe to rotate in the forward direction. At this time, the driving pipe will drive the deflector to rotate and adjust the angle of the deflector through the shift block, so that the deflector extracts the upper air and discharges it downward, thereby extracting the gas in the heater and discharging it into the preheating tank synchronously. The positively rotating driving shaft will drive the asphalt in the preheating tank to move upward through the first spiral blade to achieve preheating of the asphalt. When discharging the asphalt, the motor needs to be started to drive the driving pipe to rotate in the reverse direction. At this time, the driving pipe will drive the deflector to rotate and adjust the angle of the deflector through the shift block again, so that the deflector The device draws air from above and discharges it downward, thereby extracting the gas in the heater and discharging it into the preheating tank simultaneously, achieving a continuous heating effect. At the same time, the counter-rotating docking head will drive the mounting cylinder to rotate, causing the first spiral blade and the second spiral blade to synchronously discharge asphalt downward, ensuring the heat of the asphalt while accelerating the discharge of the asphalt. When in use, the device only needs to control the forward and reverse rotation of the motor to achieve the heating and accelerated discharge of the asphalt in the preheating tank, avoiding overly complicated operations that affect the user's control of the device during use and reducing the difficulty of using the device, so that the device can be suitable for use by people of different cultural levels, thereby achieving the effect of automatic preheating and discharging.

[0030] 2. The present invention also designs the fan blades, the shifting block, the cleaning rod, the docking cover and the heater. When preheating the asphalt, the motor needs to be started to drive the driving pipe to rotate in the forward direction. At this time, the driving pipe will drive the installation sleeve, the rotating rod and the fan blades to rotate. At this time, the fan blades will be squeezed by the shifting block during the contact with the shifting block and the angle will be tilted, so that when the fan blades rotate forward, they will extract the hot air in the heater and the gas in the connecting ring for discharge. When the gas enters the driving pipe and the cleaning rod along the exhaust pipe, the cleaning rod will discharge the gas through the aeration port. In addition, since there are only two aeration holes for the drive pipe to drive the docking cover to rotate, the air in the driving pipe can be discharged. Exhaust, so the gas will accumulate in the sealing cylinder, and when the aeration hole is connected to the docking cover, the gas will be compressed and discharged. At this time, a large amount of gas will be discharged along the cleaning rod to achieve the effect of automatic aeration, so that the device can not only turn the asphalt over during use, but also improve the preheating effect of the asphalt below through continuous aeration heating from below, and after the asphalt absorbs the heat in the air, the excess gas will be discharged along the connecting ring, thereby avoiding the occurrence of excessive air pressure in the preheating tank, and the heat in the air can be recovered and reused, thereby saving the use cost of the device.

[0031] 3. The present invention also designs a driving shaft, a docking joint, a docking groove and a second spiral blade. When discharging asphalt, it is necessary to start the motor to drive the driving tube to rotate in the opposite direction. At this time, the driving tube will drive the mounting sleeve to rotate and adjust the angle of the fan blade accordingly through the shift block again, so that the fan blade will still draw air from above and discharge it downward when rotating in the opposite direction, and the reversely rotating driving shaft and the elastic telescopic rod will drive the docking joint to be stuck in the docking groove, so that the vertical surface of the docking joint and the vertical surface of the docking groove are docked, thereby synchronously driving the mounting tube and the second spiral blade to rotate. Since the first spiral blade in the reverse rotating state will push the asphalt downward, the asphalt will accumulate at the bottom of the preheating tank. As the mounting tube rotates, the asphalt will be discharged along the discharge groove and the discharge pipe, and the second spiral blade will assist the discharge of the asphalt to prevent the asphalt from accumulating and adhering to the discharge pipe, so that the device can accelerate the discharge of the asphalt by running the motor in the opposite direction, and cooperate with the second spiral blade to accelerate the outflow of the asphalt, reduce the time of the asphalt in the discharge pipe, and prevent the asphalt from cooling down and adhering to the discharge pipe after contacting the outside air, thereby improving the stirring and discharging efficiency of the device.

By designing the motor 102-1, the deflector 103-3, the first spiral blade 105-4 and the second spiral blade 107-8, when preheating the asphalt, the motor 102-1 needs to be started to drive the driving pipe 102-4 to rotate forward. At this time, the driving pipe 102-4 will drive the deflector 103-3 to rotate and adjust the angle of the deflector 103-3 through the shift block 103-2, so that the deflector 103-3 extracts the upper air and discharges it downward, thereby extracting the gas in the heater 108 and synchronously discharging it to the preheating tank 10 1, and the positively rotating driving shaft 105-3 will drive the asphalt in the preheating tank 101 to move upward through the first spiral blade 105-4 to preheat the asphalt. When discharging the asphalt, the motor 102-1 needs to be started to drive the driving pipe 102-4 to rotate in the opposite direction. At this time, the driving pipe 102-4 will drive the deflector 103-3 to rotate and adjust the angle of the deflector 103-3 through the shift block 103-2 again, so that the deflector 103-3 extracts the upper air and discharges it downward, thereby extracting the gas in the heater 108 and discharging it into the preheating tank 101 synchronously, achieving the effect of continuous heating. At the same time, The counter-rotating docking joint 107-3 will drive the mounting cylinder 107-4 to rotate, so that the first spiral blade 105-4 and the second spiral blade 107-8 will discharge asphalt downward synchronously, ensuring the heat of the asphalt while accelerating the discharge of the asphalt, so that when the device is in use, it is only necessary to control the forward and reverse rotation of the motor 102-1 to achieve the heating and accelerated discharge of the asphalt in the preheating tank 101, avoiding overly complicated operations during use that affect the user's control of the device, and reducing the difficulty of using the device, so that the device can be suitable for use by people of different cultural levels, thereby achieving the effect of automatic preheating and discharge.

Because an elastic telescopic rod 107-2 is provided, when the driving shaft 105-3 rotates forward, the elastic telescopic rod 107-2 will contact the docking groove 107-6 through the docking head 107-3. When the butt joint 107-3 is in contact with the butt joint 107-6, the elastic telescopic rod 107-2 is squeezed and contracted by the butt joint 107-3, and the butt joint 107-3 is difficult to drive the mounting tube 107-4 to rotate. Therefore, the blades outside the mounting tube 107-4 can be correspondingly engaged with the discharge groove 109 below the preheating tank 101, and the shape of the blades outside the mounting tube 107-4 is adapted to the shape of the discharge groove 109, thereby preventing the asphalt from leaking along the discharge groove 109 due to the rotation of the mounting tube 107-4.

[0055] Due to the setting of the shift block 103-2 in the sealing tube 103-1, the fan blades 103-305 are squeezed by the shift block 103-2 during the forward and reverse rotation and cause angular displacement, so that the fan blades 103-305 in the forward and reverse states are in a state of extracting air from above and discharging it downward, thereby ensuring the heating effect in the preheating tank 101.

[0056] As another embodiment of the present invention, the discharge assembly 107 includes a feed tube 107-1, an elastic telescopic rod 107-2 is arranged in the feed tube 107-1, and the bottom end of the elastic telescopic rod 107-2 is fixedly connected to a docking joint 107-3, and the docking joint 107-3 is clamped in a docking groove 107-6, and the docking groove 107-6 is arranged below the inner wall of the installation groove 107-5, and the installation groove 107-5 is arranged in the installation cylinder 107-4, and the installation cylinder 107-4 is composed of a cylinder body and a plurality of blades, and the installation cylinder 107 -4 is tightly welded to the top of the connecting rod 107-7, a second spiral blade 107-8 is arranged outside the connecting rod 107-7, the shape of the blade above the mounting cylinder 107-4 is adapted to the shape of the discharge trough 109, the discharge pipe 107-1 is tightly welded to the bottom of the preheating tank 101, the deflector 103-3 includes a mounting sleeve 103-301, a plurality of connecting sleeves 103-302 are fixedly connected to the outside of the mounting sleeve 103-301, and a rotating rod 103-302 is rotatably connected inside the plurality of connecting sleeves 103-302. 3-303, a plurality of friction blocks 103-304 are fixedly connected to the outside of the connecting sleeve 103-302, and the plurality of friction blocks 103-304 are all clamped on the outside of the rotating rod 103-303, and the other end of the rotating rod 103-303 is fixedly connected to the side corresponding to the fan blade 103-305, and the inner wall of the mounting sleeve 103-301 is tightly welded to the outer wall of the driving tube 102-4, and the side below the fan blade 103-305 is overlapped with the shifting block 103-2, and the sealing sleeve 103-9 is set on the driving tube 102- 4, so that during the rotation of the driving tube 102-4, the sealing sleeve 103-9 will synchronously drive the exhaust pipe 103-8 and the docking cover 103-7 to rotate, so that the docking cover 103-7 will intermittently dock with the two aeration holes 103-4 during the rotation, so that the gas in the sealing cylinder 103-1 will be discharged along the aeration holes 103-4, ensuring that the device can automatically achieve the effect of intermittent aeration during use, thereby improving the effect of turning over the asphalt accumulated at the bottom of the preheating tank 101;

[0057] By arranging a friction block 103-304 outside the connecting sleeve 103-302 and the rotating rod 103-303, it is ensured that when the fan blade 103-305 contacts the shift block 103-2 and has an angular displacement, the friction block 103-304 can position the rotating rod 103-303, thereby preventing the blade from rotating without contacting the shift block 103-2, thereby improving the stability of the device during use.

[0058] Working principle: This embodiment provides an asphalt storage tank with a preheating function. When in use, asphalt is injected into the preheating tank 101, and when the asphalt is preheated, the heater 108 and the motor 102-1 are driven by the control panel 202;

[0059] When preheating the asphalt, the motor 102-1 needs to be started to drive the driving pipe 102-4 to rotate in the forward direction. At this time, the driving pipe 102-4 will drive the deflector 103-3 to rotate and adjust the angle of the deflector 103-3 through the shift block 103-2, so that the deflector 103-3 extracts the upper air and discharges it downward, thereby extracting the gas in the heater 108 and discharging it into the preheating tank 101 synchronously, and the positively rotating driving shaft 105-3 will drive the asphalt in the preheating tank 101 to move upward through the first spiral blade 105-4 to achieve preheating of the asphalt. When discharging the asphalt, the motor 102-1 needs to be started. The driving tube 102-4 is driven to rotate in the opposite direction. At this time, the driving tube 102-4 drives the deflector 103-3 to rotate and adjusts the angle of the deflector 103-3 through the shift block 103-2 again, so that the deflector 103-3 extracts the upper air and discharges it downward, thereby extracting the gas in the heater 108 and discharging it into the preheating tank 101 synchronously, achieving a continuous heating effect. At the same time, the counter-rotating docking head 107-3 drives the installation cylinder 107-4 to rotate, so that the first spiral blade 105-4 and the second spiral blade 107-8 synchronously discharge asphalt downward, ensuring the heat of the asphalt while accelerating the discharge of the asphalt;

[0060] When preheating asphalt, it is necessary to start the motor 102-1 to drive the driving tube 102-4 to rotate in the forward direction. At this time, the driving tube 102-4 will drive the mounting sleeve 103-301, the rotating rod 103-303 and the fan blade 103-305 to rotate. At this time, the fan blade 103-305 will be squeezed by the shift block 103-2 during the contact with the shift block 103-2 and the angle will be tilted, so that when the fan blade 103-305 rotates forward, it will extract the hot air in the heater 108 and the gas in the connecting ring 106 for discharge. When entering the driving pipe 102-4 and the cleaning rod 105-5 along the exhaust pipe 103-8, the cleaning rod 105-5 will discharge the gas through the aeration port 105-6, and because there are only two aeration holes 103-4 for exhaust when the driving pipe 102-4 drives the docking cover 103-7 to rotate, the gas will accumulate in the sealing tube 103-1, and when the aeration holes 103-4 are connected to the docking cover 103-7, the gas will be compressed and discharged. At this time, a large amount of gas will be discharged along the cleaning rod 105-5 to achieve the effect of automatic aeration.

[0061] When discharging asphalt, it is necessary to start the motor 102-1 to drive the driving tube 102-4 to rotate in the opposite direction. At this time, the driving tube 102-4 will drive the mounting sleeve 103-301 to rotate and adjust the angle of the fan blade 103-305 accordingly through the shift block 103-2 again, so that the fan blade 103-305 will still draw air from above and discharge it downward when rotating in the opposite direction, and the reverse rotating driving shaft 105-3 and the elastic telescopic rod 107-2 will drive the docking joint 107-3 to be stuck in the docking groove 107-6, so that the vertical surface of the docking joint 107-3 is docked with the vertical surface of the docking groove 107-6, thereby synchronously driving the mounting cylinder 107-4 and the second spiral blade 107-8 to rotate. Since the first spiral blade 105-4 in the reverse rotating state will push the asphalt downward, the asphalt will accumulate at the bottom of the preheating tank 101. As the mounting cylinder 107-4 rotates, the asphalt will be discharged along the discharge groove 109 along the discharge pipe 107-1.
