Description

Technical Field

[0001] This utility model relates to the field of asphalt addition technology, specifically to an asphalt addition device. Background Technology

[0002] When preparing asphalt mixtures in the laboratory, the experimenter needs to manually add the asphalt to the mixing pot. However, the actual operation is quite cumbersome. First, the asphalt bucket is placed in an oven and heated until the asphalt is flowable. Then, a portion of the asphalt is poured into a container for later use. Next, the asphalt in the container is kept heated while stirring and adding flame retardants, etc., while weighing the mixture. Finally, the mixed asphalt is poured into the mixing pot. Based on experience, a portion is poured in first, and the remaining asphalt in the container is weighed. The difference between the weight of the remaining asphalt and the initial weight of the asphalt is calculated. If the difference is not equal to the amount of asphalt to be added, more needs to be added. This process is repeated until the difference is equal. However, the above method of adding asphalt is somewhat cumbersome and there is a possibility that too much asphalt may be added and cannot be corrected.

[0003] Therefore, in order to address the above problems, an asphalt addition device is proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] An asphalt adding device includes an asphalt tank for storing asphalt, which is placed inside an insulated tank. A lid is located on top of the insulated tank, and a handle is attached to the outside of the lid. A weighing component is located at the bottom of the insulated tank, in contact with the asphalt tank, for weighing the asphalt. An outlet hole is formed through the asphalt tank for asphalt to flow out, and the outlet hole connects to a conveying component that penetrates the side wall of the insulated tank for guiding and outputting the asphalt. A heating component is located on the outside of the asphalt tank inside the insulated tank for heating the asphalt. A receiving cavity is located at the bottom of the asphalt tank, and an oil tank is located within the receiving cavity, connected to the conveying component. A movable adjustment component is located at the bottom of the outside of the insulated tank for moving the insulated tank and adjusting its height.

[0007] Preferably, the weighing assembly includes a weighing plate and a weighing sensor. The weighing plate is movably disposed inside the insulated barrel, and the weighing sensor is disposed between the bottom of the weighing plate and the bottom of the insulated barrel. The upper part of the weighing plate is used to place the asphalt barrel.

Detailed Implementation

[0024] 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.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution:

[0026] An asphalt dispensing device includes an asphalt tank 1 for storing asphalt, which is placed inside an insulated tank 2. A lid 3 is located on top of the insulated tank 2, and a handle is provided on the outside of the lid 3 for easy removal. Both the insulated tank 2 and the lid 3 are made of commercially available insulation materials. A weighing component 4 is located at the bottom of the insulated tank 2, on which the asphalt tank 1 is placed for real-time weighing of the entire weight of the asphalt tank 1. An outlet hole 5 is formed through the bottom of the asphalt tank 1 for asphalt to flow out. The outlet hole 5 is connected to a conveying component 6, which penetrates the side wall of the insulated tank 2 to guide and output the asphalt, improving safety. A heating component 7 is located on the outside of the asphalt tank 1 inside the insulated tank 2 for heating the asphalt. A receiving cavity 8 is located at the bottom of the asphalt tank 1, and an oil tank 10 is located inside the receiving cavity 8, connected to the conveying component 6. A movable adjustment component 9 is located at the bottom of the outside of the insulated tank 2 to move the insulated tank 2 and adjust its height.

[0027] In this embodiment, the weighing component 4 includes a weighing plate 41 and a weighing sensor 42. The weighing plate 41 is movably disposed inside the insulated barrel 2. The weighing sensor 42 is disposed between the bottom of the weighing plate 41 and the bottom of the insulated barrel 2. The upper end of the weighing plate 41 is used to place the asphalt barrel 1. The weighing sensor 42 is used to weigh the weight of the asphalt barrel 1 and the asphalt inside it on the weighing plate 41 in real time, so as to achieve accurate addition of asphalt.

[0028] In this embodiment, the asphalt bucket 1 is movably disposed inside the insulated bucket 2. The asphalt bucket 1 includes an asphalt cavity at the upper end for storing asphalt and a receiving cavity 8 at the lower end. An oil pump 11 is also disposed inside the receiving cavity 8. The two ends of the oil pump 11 are connected to the oil tank 10 and the conveying assembly 6 through oil pipelines. Preferably, a pressure compensator is also included, which is connected between the oil pump 11 and the conveying assembly 6 to improve the stability of the device.

[0029] In this embodiment, the heating component 7 includes an electric heating layer with an electric heating wire disposed inside the layer and surrounding the outside of the asphalt cavity for heating the asphalt after being energized. A temperature sensor is also disposed on the asphalt cavity, preferably a laser thermometer, with the measuring end of the laser thermometer facing the asphalt inside the asphalt tank 1, for measuring the real-time temperature of the asphalt inside the asphalt cavity. This avoids the possibility of inaccurate temperature measurement by the patch thermometer due to the influence of the heating component 7, thus improving the practicality of the device and the accuracy of temperature measurement.

[0030] In this embodiment, the conveying assembly 6 includes a spherical chamber 61 and a telescopic tube 62. The spherical chamber 61 has two openings, a first opening 611 and a second opening 612, with their axes passing through the center of the chamber. This ensures that when asphalt passes through the chamber, a cavity exists at the upper end of the chamber, preventing it from being completely filled with asphalt. The outer side of the spherical chamber 61 is supported by a support frame 15, which does not affect the heating of the heating assembly 7. The first opening 611 is connected to the outlet hole 5 via a switch assembly 12, and the second opening 612 is connected to one end of the telescopic tube 62. The other end of the telescopic tube 62 is used for asphalt discharge. The end of the telescopic tube 62 away from the spherical chamber 61 has an external thread, allowing for a threaded connection to a sealing cap. This sealing cap prevents overfilling after sufficient asphalt has been added and prevents asphalt overflow after the tube retracts. The telescopic tube 62 also includes an oil cavity 621, which is connected to… The oil pump 11 controls the extension and retraction of the telescopic pipe 62. When hydraulic oil is drawn out of the oil chamber 621, the telescopic pipe 62 can extend; when hydraulic oil is filled into the oil chamber 621, the telescopic pipe 62 retracts, and the asphalt inside the telescopic pipe 62 is squeezed into the spherical chamber 61. There is a cavity in the upper part of the spherical chamber 61, and the air in the cavity is easily compressed, which prevents the asphalt pressure in the spherical chamber 61 from being too high, thus improving the safety and practicality of the device. In another embodiment, the telescopic pipe 62 is a common telescopic pipe, and the conveying component 6 also includes a telescopic cylinder. The telescopic cylinder is set outside the telescopic pipe 62, and its two ends are connected to the two ends of the telescopic pipe 62. The telescopic cylinder is connected to the oil pump, and the telescopic pipe 62 is driven by the telescopic cylinder to achieve the same effect. It is only necessary to ensure that the telescopic pipe 62 can extend and retract to avoid the problem of asphalt solidification and blockage of the telescopic pipe when no asphalt is added, thus improving the efficiency of the device.

[0031] In this embodiment, a heating and insulation layer 13 is provided on the outer surface of the spherical chamber 61. The heating and insulation layer 13 can be a silicone heating sheet, which is attached to the outer surface of the spherical chamber 61. It can heat and keep the asphalt inside the spherical chamber 61 warm, prevent the asphalt from solidifying too quickly, and improve the efficiency of the device.

[0032] In this embodiment, the switch assembly 12 includes an arc-shaped plate 121, which is slidably disposed on the spherical chamber 61. Specifically, an arc-shaped groove is formed on the outer side of the spherical chamber 61, and a slider is provided on the arc-shaped plate 121 corresponding to the groove. The slider is slidably disposed in the groove and will not come out. A switch hole 122 is formed through the arc-shaped plate 121, which can connect the outlet 611 and the outflow hole 5. By sliding the arc-shaped plate 121 on the spherical chamber 61, the position of the switch hole 122 is changed, thereby opening or closing the switch assembly. Preferably, the connection between the inlet 611 and the outlet hole 5 is a sealed sliding connection, so that the arc plate 121 can maintain a sealed connection when sliding relative to the inlet 611 and the outlet hole 5, thus preventing asphalt leakage. The specific sliding sealing structure can adopt a common sealing structure in the art, which can close the connection between the inlet 611 and the outlet hole 5 in time after the asphalt is added, thus preventing excessive addition and improving the safety of the operator.

[0033] In this embodiment, the movable adjustment component 9 includes a movable frame 91 and a movable handle 92. The movable frame 91 is set at the bottom of the heat preservation barrel 2 via a telescopic rod 93. The telescopic rod 93 is a commonly available pneumatic rod, which is economical. A caster wheel 94 is set below the movable frame 91, and the movable handle 92 is set on the outside of the heat preservation barrel 2 to facilitate the movement of the device.

[0034] In this embodiment, a control component is also included, including a display screen 14, which is disposed on the outside of the insulated barrel 2 to display the working status of the device, and a controller connected to the display screen 14, the weighing sensor 42, the temperature sensor and the heating component 7, so as to facilitate the control of the device and display the corresponding temperature, weight and other status of the device, thereby improving the practicality and accuracy of the device.

[0035] Working principle: With asphalt in the asphalt tank 1, grasp the moving handle 92 to push the device, and move the device to the adding position using the casters 94. Adjust the telescopic rod 93 to position the insulated tank 2 at a suitable height, and then power on the device. The heating component 7 heats the asphalt in the asphalt tank 1 until the temperature reaches a state where the asphalt can flow. Then, control the extension of the telescopic tube 62, and simultaneously move the arc plate 121 so that the switch hole 122 connects the outlet 611 and the outflow hole 5. At this time, the asphalt can flow into the spherical chamber 61 and pass through the telescopic tube 62 before filling the spherical chamber. 2. The asphalt flows out into the experimental mixing pot, and then the weight change of the asphalt bucket 1 on the display screen 14 is observed. When the reduced weight is equal to the weight of the asphalt to be added, the addition can be stopped. Move the arc plate 121 so that the switch hole 122 disconnects the connection between the outlet 611 and the outlet hole 5, and the asphalt no longer flows into the spherical chamber 61. Then block the outlet of the telescopic tube 62 and retract the telescopic tube 62. The asphalt in the telescopic tube 62 is back-pressed into the spherical chamber 61. The heating and insulation layer 13 can heat and insulate the asphalt in the spherical chamber 61, which facilitates the next addition of asphalt to the device.
