Description

Technical Field

[0001] This invention relates to the field of highway construction equipment technology, and in particular to a hot asphalt transportation and storage device. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic binder. In highway construction, asphalt is a widely used waterproofing and corrosion-resistant material, primarily applied to waterproofing roofs, floors, and underground structures, as well as for the preservation of timber and steel. Asphalt is also a widely used pavement structural binder in road engineering. When mixed with mineral materials of different compositions in specific proportions, it can form asphalt pavements with various structures. It is widely used on highways. When using asphalt for highway paving, the asphalt needs to be stored in large storage tanks. When needed, the asphalt in the tanks is heated before reuse.

[0003] When hot asphalt is used on a construction site, it needs to be transported to the site. Since a large amount of hot asphalt is transported, it needs to be stored in a storage tank. If the outlet of the storage tank is not scraped, the outlet will be easily blocked by asphalt if it is not discharged for a long time, and the asphalt cannot be discharged smoothly. Before using the asphalt, it needs to be heated and stirred again. Otherwise, if the hot asphalt is not hot enough, it will slowly solidify and cannot flow smoothly. Summary of the Invention

[0015] Beneficial effects

[0016] 1. The present invention has a rotating drum installed at the shaft of the motor, and stirring rods are evenly installed on the annular side wall of the rotating drum. When the motor is turned on, the rotating drum will rotate rapidly. When the stirring rods on the rotating drum rotate, they will stir the hot asphalt in the inner drum and mix the hot asphalt in the inner drum evenly. The hot asphalt is evenly mixed and is convenient to flow for paving. In this way, the fluidity of the hot asphalt can be maintained, and the hot asphalt can be easily spread and paved on the ground.

[0017] 2. This invention allows for the following steps: When preparing to discharge hot asphalt from a storage tank, first use electric push rod A to pull down the sealing scraper. This exposes the discharge hole on the fixed cover, allowing the hot asphalt in the storage tank to flow from the discharge hole into the discharge cylinder. When electric push rod A pushes the sealing scraper upward, the scraper blocks the discharge hole on the left side wall of the fixed cover, preventing the asphalt in the storage tank from being discharged from there. The sealing scraper prevents the asphalt from solidifying and clogging the discharge hole for an extended period. The sliding installation of the sealing scraper at the discharge hole prevents blockage by asphalt, thus facilitating the smooth discharge of asphalt. Furthermore, the asphalt can be reheated and stirred before use to improve the fluidity of the hot asphalt in the inner cylinder, allowing it to flow out smoothly. Since the storage tank is mounted on a vehicle traveling on the road, storing large quantities of hot asphalt in the tank at once eliminates the need for repeated transport. The hot asphalt in the storage tank can be discharged and used at any time, saving time and improving work efficiency.

[0018] 3. With this invention, when preparing to discharge hot asphalt from the inner cylinder, first use two electric push rods B to pull the sealing plates in opposite directions. At this time, the two outlets will open, and the hot asphalt will flow downward from the outlets. When the hot asphalt is no longer needed, use the electric push rods B to slide the two sealing plates in opposite directions and seal the outlets. In this way, the hot asphalt in the inner cylinder can be discharged at any time. Before the hot asphalt is discharged, it can be heated and stirred again to improve the fluidity of the hot asphalt in the inner cylinder, making it convenient for the hot asphalt to flow and spread on the ground for use.

Heating tank 4; A heating control system is fixedly installed on the left side wall of the left end door cover of heating tank 4. The heating system can be used to heat the inner cavity of heating tank 4. A fixed support ring 5 is fixedly installed on the outer annular side wall of heating tank 4. A bearing plate 6 is fixedly installed at the top of heating tank 4, and a through round hole is opened in the middle of the bearing plate 6. A through motor 601 is fixedly installed at the round hole of the bearing plate 6.

When motor 601 is turned on, rotating drum 602 will rotate rapidly. When the stirring rods on rotating drum 602 rotate, they will stir the hot asphalt in inner drum 403, making the hot asphalt in inner drum 403 evenly mixed. The hot asphalt is evenly mixed and convenient for flow and paving.

[0035] The heating base 2 has evenly spaced through heating holes 201 at its upper end groove. Heat radiated from the heating plate 202 passes through these holes 201 into the storage tank 3, heating and insulating the asphalt inside. A heating plate 202 is installed at a fixing hole at the lower end of the heating base 2. A side block 203 is fixedly installed on the right side wall of the heating base 2, with a cylindrical groove in the middle. An electric push rod A204 is fixedly installed in the cylindrical groove of the side block 203. The upper end of the electric push rod A204 penetrates the bottom right end of the storage tank 3. A sealing ring 205 is fitted at the extension / retraction point of the electric push rod A204, with the top of the sealing ring 205 firmly attached to the lower end of the storage tank 3. A sealing scraper 206 is fixedly installed at the top. When preparing to discharge hot asphalt from storage tank 3, the electric push rod A204 is used to pull the sealing scraper 206 downward. At this time, the discharge hole on the fixed cover 304 will be exposed, and the hot asphalt in storage tank 3 will flow from the discharge hole into discharge cylinder 307. When the electric push rod A204 is used to push the sealing scraper 206 upward, the sealing scraper 206 will block the discharge hole on the left side wall of the fixed cover 304, and the asphalt in storage tank 3 cannot be discharged from here. With the sealing block of the sealing scraper 206 at the discharge hole, the asphalt cannot solidify and block at the discharge hole for a long time. A slider 207 is fixedly installed on the right side wall of the sealing scraper 206, and the slider 207 is slidably installed in the chute 306.

[0036] The storage tank 3 has two locking sealing caps 301 installed at its upper inlet. After the hot asphalt is processed, the sealing caps 301 are lifted and opened, and then the hot asphalt is injected into the storage tank 3. A retaining ring 302 is fixedly installed on the left side wall of the storage tank 3. When the storage tank 3 is not in use and the inner cavity needs to be cleaned, the door cover at the left end of the storage tank 3 is removed, and then the inner cavity of the storage tank 3 is cleaned. The retaining ring 302 is inserted into the retaining groove 303. A ring-shaped retaining groove 303 is opened on the right side wall of the door cover at the left end of the storage tank 3. A fixing cap 304 is fixedly installed on the right side wall of the storage tank 3. A through discharge hole is provided at the lower end. An arc-shaped limiting block 305 is fixedly installed on the left side wall of the fixed cover 304. The top of the sealing scraper 206 is in close contact with the concave surface of the limiting block 305. When the sealing scraper 206 slides upward, it is blocked by the limiting block 305 and cannot continue to slide upward. At this time, the sealing scraper 206 will block the discharge hole and restrict the sealing scraper 206. Symmetrical sliding grooves 306 are provided at the lower end of the left side wall of the fixed cover 304. A downwardly inclined discharge cylinder 307 is fixedly installed at the right end of the discharge hole of the fixed cover 304, and a valve is installed at the upper end of the discharge cylinder 307.

[0037] The heating barrel 4 has an electric heating tube 401 installed on the side wall of its inner cavity. The electric heating tube 401 heats the hot asphalt inside the heating barrel 4, improving its fluidity. A bearing ring 402 is fixedly installed at the lower end of the side wall of the inner cavity of the heating barrel 4. An inner cylinder 403 is installed inside the inner cavity of the heating barrel 4. The asphalt in the discharge cylinder 307 is discharged from the right end into the lower inner cylinder 403. The hot asphalt in the inner cylinder 403 is then stirred evenly, and the hot asphalt flows downwards from the two outlets 405 into the lower telescopic pipe 407. A limit ring 404 is fixedly installed at the top of the inner cylinder 403. The bottom of 04 is attached to the top of the heating barrel 4, and the two ends of the limiting ring 404 are respectively provided with bearing grooves. The bottom of the inner cavity of the heating barrel 4 is provided with mutually symmetrical outlets 405, and the inner side wall of the outlet 405 is provided with mutually symmetrical guide grooves 406. The two outlets 405 are respectively fixedly installed with downward telescopic pipes 407. The lower end of the telescopic pipe 407 can move up and down. When the lower end of the telescopic pipe 407 moves downward, the distance between the opening of the lower end of the telescopic pipe 407 and the ground will be shortened, so that the hot asphalt in the telescopic pipe 407 can flow to the ground. The upper end of the telescopic pipe 407 is fixedly installed at the fixed groove 102.

[0038] The fixed support ring 5 has three vertically downward support columns 501 fixedly installed at its bottom. The lower ends of the support columns 501 are fixedly inserted into the fixing grooves of the truck bed 1. The three support columns 501 provide fixed support for the fixed support ring 5 above, and the fixed support ring 5 also provides fixed support for the heating tank 4. The bottom of the fixed support ring 5 has symmetrically arranged cantilever arms 502 fixedly installed. The lower ends of the cantilever arms 502 have through rod holes. Electric push rods B503 are fixedly installed at the rod holes of the two cantilever arms 502 respectively. Sealing plates 504 are fixedly installed at the opposite ends of the two electric push rods B503 respectively, in preparation for discharging the hot asphalt in the inner cylinder 403. When hot asphalt is not in use, the two electric push rods B503 are used to pull the sealing plate 504 in opposite directions. At this time, the two outlets 405 will open, and the hot asphalt will flow downward from the outlets 405. When the hot asphalt is not in use for the time being, the two sealing plates 504 are slid in opposite directions using the electric push rods B503 to seal the outlets 405 and prevent the hot asphalt in the inner cylinder 403 from continuing to flow downward. Guide strips 505 are fixedly installed on the two side walls of the sealing plate 504, and the guide strips 505 are slidably installed in the guide grooves 406. The two sealing plates 504 are fixedly installed with baffles 506 at the opposite ends.

[0039] The specific usage and function of this embodiment: In this invention, the sealing cover 301 is lifted upwards to open, and then hot asphalt is injected into the storage tank 3. The heat emitted from the heating plate 202 will pass through the heating hole 201 into the storage tank 3 to heat and keep the asphalt in the inner cavity of the storage tank 3 warm. First, the electric push rod A204 is used to pull the sealing scraper 206 downwards. At this time, the discharge hole on the fixed cover 304 will be exposed, and the hot asphalt in the storage tank 3 will flow from the discharge hole into the discharge cylinder 307. The asphalt in the discharge cylinder 307 will be discharged from the right end into the lower inner cylinder 403. When the motor 601 is turned on, the rotating drum 602 will rotate rapidly. When the stirring rod on the rotating drum 602 rotates, it will stir the hot asphalt in the inner cylinder 403, making the hot asphalt in the inner cylinder 403 even. Then, the two electric push rods B503 are used to pull the sealing plate 504 in opposite directions. The two outlets 405 will open, and the hot asphalt will flow downward from the outlets 405 into the lower telescopic pipe 407. When the lower end of the telescopic pipe 407 is moved downward, the distance between the lower end of the telescopic pipe 407 and the ground will be shortened, making it easier for the hot asphalt in the telescopic pipe 407 to flow to the ground. When the hot asphalt is no longer in use, the electric push rod A204 is used to push the sealing scraper 206 upward. The sealing scraper 206 will block the discharge hole on the left side wall of the fixed cover 304, and the asphalt in the storage tank 3 cannot be discharged from here. With the sealing scraper 206 blocking the discharge hole, the asphalt cannot solidify and block the discharge hole for a long time. Then, the electric push rod B503 is used to slide the two sealing plates 504 in opposite directions and seal the outlet 405 with the sealing plates 504 to prevent the hot asphalt in the inner cylinder 403 from continuing to flow downward.
