Description

A high-performance modified asphalt quantitative transfer device Technical Field

[0001] This utility model relates to the technical field of modified asphalt quantitative transfer devices, specifically a high-performance modified asphalt quantitative transfer device. Background Technology

[0002] High-performance modified asphalt is a key material for improving the quality of road engineering, and is especially suitable for harsh environments such as heavy traffic and extreme climates. When high-performance modified asphalt is used in road paving construction, building waterproofing and other fields, quantitative transfer devices are required to provide metering and transportation of the modified asphalt.

[0003] Existing quantitative transfer devices are prone to solidification during the transfer of modified asphalt in extreme environments, causing the modified asphalt to be unable to flow normally. This affects the feeding speed of the quantitative transfer device for modified asphalt, thereby affecting the progress of road construction.

[0004] According to announcement number CN219929032U, a modified asphalt quantitative transfer device includes a control box with a feed pipe fixedly connected to one side. The feed pipe has a valve and a protective mechanism, comprising a fixed cylinder, a connecting cylinder, a support cylinder, a compression pipe, an inlet pipe, and a shielding cylinder. The support cylinder is connected to the fixed cylinder via the connecting cylinder, and the inlet pipe is connected to the support cylinder via the compression pipe. The inlet pipe is located inside the shielding cylinder, and the fixed cylinder has an annular groove. This invention utilizes the cooperation of the fixed cylinder, connecting cylinder, support cylinder, compression pipe, inlet pipe, shielding cylinder, and feed pipe. The support cylinder drives the connecting cylinder to move, the connecting cylinder slides on the fixed cylinder, and the shielding cylinder shields the inlet pipe. The inlet pipe connects to the receiving port of a transport vehicle, thus facilitating the shielding and protection of the modified asphalt feed and making it suitable for transport vehicles of different heights for receiving and transferring modified asphalt.

[0005] As described above, the quantitative transfer device only improves the anti-splashing effect of modified asphalt feeding. However, under extreme conditions, the modified asphalt may solidify during the transfer process, preventing it from flowing normally and affecting the feeding speed of the device, thus impacting the progress of road construction. To address these issues, an improved high-performance modified asphalt quantitative transfer device has been proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a high-performance modified asphalt quantitative transfer device. Adding an anti-sedimentation mechanism to the quantitative transfer device not only prevents the modified asphalt from settling but also improves its flowability. Furthermore, installing protective components on the surface of the conveying pipe allows the quantitative transfer device to provide heating and insulation to the conveying pipe under extreme conditions, preventing the modified asphalt from solidifying during transport, avoiding blockages in the conveying pipe, and ensuring the normal flow of the modified asphalt. This avoids affecting the feeding speed of the quantitative transfer device, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-performance modified asphalt quantitative transfer device, comprising a storage tank, an anti-sedimentation mechanism provided in the inner cavity of the storage tank, a conveying pipe connected to the lower end of the storage tank, a protective component providing heat insulation for the conveying pipe on its surface, fasteners providing a fixing effect between the protective component and the conveying pipe on its surface, and a protective cover preventing splashing when discharging high-performance modified asphalt at the lower end of the conveying pipe.

[0008] Preferably, a flow control valve is installed at the upper end of the conveying pipe, and a flow meter that works in conjunction with the flow control valve is installed at the lower end of the conveying pipe.

[0009] Preferably, the protective component includes a heating tube, which is spirally wound around the surface of the conveying tube. An insulation shell is fitted over the surface of the heating tube, and both ends of the insulation shell are fixed to the conveying tube. The surface of the insulation shell is covered with insulation cotton, and fasteners are installed at both ends of the insulation cotton. One end of the heating tube is connected to a connector.

[0010] Preferably, the fastener includes a buckle that snaps onto the surface of the insulation cotton. Both ends of the buckle have positioning holes, and a positioning bolt is inserted into the inner cavity of the positioning hole. One end of the positioning bolt is threaded with a threaded cap.

[0011] Preferably, the anti-sedimentation mechanism includes a stepper motor, which is installed on the top of the storage tank. The output shaft of the stepper motor is connected to a rotating shaft, and a spiral stirring blade is installed on the rotating shaft to provide a stirring effect for the high-performance modified asphalt.

[0012] Preferably, the two ends of the rotating shaft are rotatably connected to a support frame via bearings, and the outer wall of the support frame is fixed to the inner wall of the liquid storage tank.

[0013] Preferably, the protective cover is fixedly connected to the conveying pipe via a flange, and the protective cover is funnel-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a high-performance modified asphalt quantitative transfer device as shown in Figures 1-4, including a storage tank 1, an anti-sedimentation mechanism 2 in the inner cavity of the storage tank 1, a conveying pipe 3 connected to the lower end of the storage tank 1, a protective component 4 providing heat insulation for the conveying pipe 3, and fasteners 5 providing a fixing effect between the protective component 4 and the conveying pipe 3. A protective cover 6 is installed at the lower end of the conveying pipe 3 to prevent splashing when discharging high-performance modified asphalt. The addition of the anti-sedimentation mechanism 2 to the quantitative transfer device not only prevents the modified asphalt from settling, but also improves the flow guiding effect of the modified asphalt. The installation of the protective component 4 on the surface of the conveying pipe 3 enables the quantitative transfer device to provide heating and heat insulation for the conveying pipe 3 in extreme environments, preventing the modified asphalt from solidifying during the transportation process, avoiding blockage of the conveying pipe 3, and ensuring the normal flow of the modified asphalt, thus avoiding affecting the discharging speed of the modified asphalt by the quantitative transfer device.

[0024] A flow control valve 7 is installed at the upper end of the conveying pipe 3, and a flow meter 8, which works in conjunction with the flow control valve 7, is installed at the lower end of the conveying pipe 3. The flow control valve 7 is installed at the upper end of the conveying pipe 3 to control the flow rate of modified asphalt, and the flow meter 8 is installed at the lower end of the conveying pipe 3 to work in conjunction with the flow control valve 7. Therefore, the quantitative transfer device can accurately control the amount of modified asphalt conveyed by the coordinated work of the flow control valve 7 and the flow meter 8, so as to meet the precise needs of different construction scenarios for the amount of modified asphalt used.

[0025] Note: The flow control valve 7 and flow meter 8 are existing technology products. Therefore, the specific working principle of the flow control valve 7 and flow meter 8 is not described in detail. The flow control valve 7 and flow meter 8 used in this invention can be selected according to the size of the delivery pipe 3, so no specific model is described.

[0026] The protective component 4 includes a heating tube 41, which is spirally wound around the surface of the conveying pipe 3. An insulation shell 42 is fitted over the surface of the heating tube 41, and both ends of the insulation shell 42 are fixed to the conveying pipe 3. The surface of the insulation shell 42 is covered with insulation cotton 43, and fasteners 5 are installed at both ends of the insulation cotton 43. One end of the heating tube 41 is connected to a connector 44, which connects to the heating tube 41 and facilitates connection to an external power source. When the heating tube 41 is powered on, it generates heat to provide heat to the conveying pipe 3. The insulation shell 42 is fitted over the surface of the heating tube 41, providing initial heat insulation. Then, the insulation cotton 43 is covered over the surface of the insulation shell 42 to further reduce heat loss, ensuring that the conveying pipe 3 can maintain a suitable temperature in extreme environments, preventing the modified asphalt from solidifying, and avoiding blockage of the conveying pipe 3.

[0027] Fastener 5 includes a clip 51, which snaps onto the surface of the insulation cotton 43. Both ends of the clip 51 have positioning holes 52, and positioning bolts 53 are inserted into the inner cavity of the positioning holes 52. One end of the positioning bolts 53 is threaded with a threaded cap 54. By snapping the clip 51 onto the surface of the insulation cotton 43, the positioning holes 52 provide an installation position for the positioning bolts 53. During installation, the positioning bolts 53 are inserted into the positioning holes 52, and then the threaded caps 54 are screwed on. By tightening the threaded caps 54, the clip 51 is firmly fixed to the insulation cotton 43, thereby stably fixing the entire protective assembly 4 onto the conveying pipe 3. This ensures that the protective assembly 4 will not loosen or fall off during transportation, thus ensuring the insulation effect and stability of the protective assembly 4.

[0028] The anti-sedimentation mechanism 2 includes a stepper motor 21, which is installed on the top of the storage tank 1. The output shaft of the stepper motor 21 is connected to a rotating shaft 22, and a spiral stirring blade 23 is installed on the rotating shaft 22 to provide a stirring effect for the high-performance modified asphalt. The spiral stirring blade 23 is driven by the stepper motor 21 to stir, which effectively prevents the modified asphalt from settling, ensures the uniformity of the modified asphalt, improves its flow guiding effect, and avoids the quality problem of the modified asphalt being affected by the settling.

[0029] The two ends of the rotating shaft 22 are rotatably connected to the support frame 9 through bearings. The outer wall of the support frame 9 is fixed to the inner wall of the liquid storage tank 1, which makes the rotating shaft 22 more stable during rotation, reduces shaking and friction, and ensures that the spiral stirring blade 23 can smoothly stir the modified asphalt.

[0030] The protective cover 6 is fixedly connected to the conveying pipe 3 by a flange 10. The flange 10 connection ensures the stability of the connection between the protective cover 6 and the conveying pipe 3. The protective cover 6 is funnel-shaped with a large opening, which can effectively guide the modified asphalt flowing out of the conveying pipe 3, causing it to fall in a concentrated manner and preventing the modified asphalt from splashing in all directions.

[0031] In practical use, the stepper motor 21 in the storage tank 1 first drives the rotating shaft 22 and the spiral stirring blade 23 to rotate, preventing the modified asphalt from settling and improving the guiding effect. Then, the modified asphalt is transported through the conveying pipe 3. During the transportation process, the flow control valve 7 at the upper end and the flow meter 8 at the lower end cooperate to accurately control the flow rate of the modified asphalt to achieve quantitative transportation. Subsequently, the heating tube 41 in the protective component 4 is powered by an external power source through the connector 44 and spirally wraps around the surface of the conveying pipe 3 to generate heat, providing heat insulation for the pipeline of the conveying pipe 3 and preventing the modified asphalt from solidifying in extreme environments. At the same time, the heat insulation shell 42 and heat insulation cotton 43 can reduce heat loss from the conveying pipe 3. The protective component 4 is firmly fixed to the conveying pipe 3 by the fasteners 5. The funnel-shaped protective cover 6 at the lower end of the conveying pipe 3 is fixedly connected to the conveying pipe 3 through the flange 10 to guide the asphalt discharge and prevent splashing.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
