Description

Technical Field

[0001] The utility model relates to the field of asphalt performance measurement, in particular to a measuring device for the remaining depth of asphalt in storage and an asphalt storage container. Background Technique

[0002] The usage amount of asphalt occupies a significant position in the quality of subsequent mixtures and project costs. Therefore, in general projects, it is necessary to accurately estimate the remaining amount of asphalt after daily production, because the remaining amount is a crucial reference value for reviewing the asphalt-aggregate ratio and controlling the quantity of asphalt purchased. This is because the accurate estimation of the remaining amount of asphalt is directly related to the control of the asphalt-aggregate ratio of asphalt mixtures, and the control of the asphalt-aggregate ratio affects the pavement quality. In project costs, asphalt accounts for a large proportion, and accurately estimating the remaining amount helps control costs and avoid waste.

[0003] Traditional estimation methods mainly estimate the amount of asphalt through the float in the asphalt tank, but this method has obvious errors and failure problems. In particular, the up and down error of the float estimation can reach 1-2 tons, and there is a risk of the float being stuck and the estimation failing, unable to provide accurate remaining amount data. Or measure the height of the asphalt to estimate, mainly by inserting a ruler into the container. After the asphalt is produced, it needs to cool down. If measured directly with a ruler, the asphalt will adhere to the ruler under the heated state; when the measurement is completed, the asphalt cools down slightly, resulting in a situation that is difficult to clean. If the asphalt is not removed in time, it will block the scale, and if the asphalt cannot be removed and put back into the container in time, it will also affect the accuracy of the estimation.

[0033] Such as Figures 1-3 , a measuring device for the remaining depth of asphalt storage, comprising: a metal component 1, a heat insulation component 2, a metal connection seat 3 and a heating device 4;

[0034] The metal connection seat 3 is installed at the upper end of the metal component 1; a component connection notch 21 is provided at the bottom of the heat insulation component 2; the metal connection seat 3 is detachably limited in the component connection notch 21, so that the heat insulation component 2 is detachably limited at the upper end of the metal component 1;

[0035] A hollow cavity 11 is provided inside the metal component 1, and the heating device 4 is arranged in the hollow cavity 11 for heating the metal component 1; a heat insulation layer 22 is provided on the outer surface of the heat insulation component 2;

[0036] Both the metal component 1 and the heat insulation component 2 are provided with a scale structure 10 on the outer surface.

[0037] This solution provides a measuring device for the remaining depth of asphalt storage, which assembles the metal component 1 and the heat insulation component 2 into one body through the metal connection seat 3. The scale structure 10 on the surfaces of both can measure the height of asphalt in the tank, and the heating device 4 in the metal component 1 can also be started to heat the metal component 1, so as to facilitate the cleaning of the asphalt attached to the metal component 1 after measurement, and solve the problem that it is difficult to clean the asphalt storage container after measuring the remaining amount of asphalt.

[0038] Specifically, for one of the methods of measuring the remaining depth of asphalt storage, the basic dimensions of the asphalt container can be measured in advance, such as parameters of the asphalt container like length and radius. When the asphalt arrives, the measuring device is placed into the asphalt container, then the asphalt is placed in the asphalt container, and the measuring device of this solution is used to measure the height of the asphalt. There is a scale structure 10 on the outer surfaces of both the metal component 1 and the heat-insulating component 2. The metal component 1 and the heat-insulating component 2 are successively inserted into the asphalt container from top to bottom, and the height of the asphalt can be directly obtained through the scale structure 10. Then, a series of algorithms are used to calculate the theoretical mass of the asphalt. For example, according to the shape of the container, the volume of the asphalt container is calculated through the basic dimensions of the asphalt container, and then the density of the asphalt is obtained. Theoretical mass = bottom area of the asphalt container × height of the asphalt × density of the asphalt. The actual mass can be measured according to the weighing scale in the asphalt container, or before placing the asphalt in the asphalt container, the mass of the asphalt is measured first to obtain a correction coefficient. Correction coefficient = actual mass ÷ theoretical mass. When the subsequent measuring device conducts a remaining amount test on this batch of asphalt each time, the measurement is carried out according to the formula: theoretical mass = bottom area of the asphalt container × height of the asphalt × density of the asphalt × correction coefficient. When the asphalt is heated before measurement or has a relatively high storage temperature, it may be in a heated state during measurement, and the asphalt will adhere to the metal component 1 when it comes into contact with the metal component 1. And when the temperature drops slightly after measurement, the asphalt will adhere to the metal component 1. Therefore, the heating device 4 in the hollow cavity 11 of the metal component 1 can be activated. The heating device 4 will heat the metal component 1, so that the outer surface of the metal component 1 is heated to soften the asphalt on the surface, and the asphalt is more easily separated from the outer surface of the metal component 1, making the cleaning of the asphalt more convenient. At the same time, the asphalt can be detached on the spot and put back into the asphalt container after measurement, avoiding waste of asphalt and more importantly, avoiding the influence of the loss of the asphalt adhering to the metal component 1 after each measurement on the asphalt-aggregate ratio. The heat-insulating layer 22 on the heat-insulating component 2 has a heat-insulating function and can be used to lift the entire measuring device manually. The temperature of the metal component 1 has little influence on the temperature of the heat-insulating component 2, which is convenient for manual holding.

[0039] Optimally, the heating device 4 includes: a heating resistance wire 41 and a heating wire 42;

[0040] The heating resistance wire 41 is arranged in the hollow cavity 11, and the heating wire 42 is electrically connected to the heating resistance wire 41.

[0041] In the optimal embodiment of this solution, the heating resistance wire 41 is used to heat the hollow cavity 11. This is because the heating effect of the heating resistance wire 41 is good and the heating speed is fast, and it can heat the metal component 1 within a short waiting time to make the surface temperature of the metal component 1 reach the softening temperature of the asphalt. The heating wire 42 is electrically connected to the heating resistance wire 41, and the heating effect is achieved by using the thermal effect generated by the current passing through the heating resistance wire 41.

[0042] Optimally, the heating wire 42 is detachably connected to the heating resistance wire 41;

[0043] Above the component connection notch 21 of the heat insulation component 2, there is a heat insulation through-hole 23; after passing through the heat insulation through-hole 23 and the component connection notch 21, the heating wire 42 is connected to the heating resistance wire 41.

[0044] In this solution, it is preferred that the heating wire 42 is connected to the heating resistance wire 41 in a detachable manner, and the heating wire 42 can be installed or removed according to the usage situation; when measuring the remaining storage depth, the heating wire 42 can be removed to avoid the heating wire 42 affecting the measurement operation of the construction personnel; after the measurement is completed, the heating wire 42 can pass through the heat insulation through-hole 23 and the component connection notch 21 and then be electrically connected to the heating resistance wire 41 in the hollow cavity 11 to heat and clean the asphalt on the surface of the metal component 1.

[0045] Optimally, the metal connection seat 3 is provided with a seat through-hole 31 communicating with the hollow cavity 11; after passing through the heat insulation through-hole 23, the component connection notch 21 and the seat through-hole 31, the heating wire 42 is connected to the heating resistance wire 41.

[0046] In a general embodiment, an opening can be directly formed at any position of the metal component 1 to expose the hollow cavity 11, so as to facilitate the heating wire 42 to extend into the hollow cavity 11. In the optimal embodiment, a seat through-hole 31 can be directly designed on the metal connection seat 3. After the heating wire 42 passes through the heat insulation through-hole 23, the component connection notch 21 and the seat through-hole 31 and is connected to the heating resistance wire 41, the heat insulation through-hole 23, the component connection notch 21 and the seat through-hole 31 can be distributed on the same straight line, and the structure of the measuring device is more concise.

[0047] Optimally, the power connection end of the heating resistance wire 41 is located in the seat through-hole 31, and the heating wire 42 is connected to the power connection end of the heating resistance wire 41 at the seat through-hole 31.

[0048] The seat through-hole 31 is located on the metal connection seat 3, and the metal connection seat 3 is installed at the upper end of the metal component 1. Therefore, when connecting the power supply to the heating resistance wire 41, the heating wire 42 can be directly electrically connected to the heating resistance wire 41 at the seat through-hole 31 to complete the power connection, which is the most convenient for power-on.

[0049] Optimally, the outer surface of the metal connection seat 3 is provided with an external thread structure 32; the component connection notch 21 is provided with an internal thread structure 211; the metal connection seat 3 is in threaded fit with the component connection notch 21, so that the heat insulation component 2 is detachably limited to the upper end of the metal component 1.

[0050] The metal connecting base 3 can be provided with a base through-port 31 on the inner side for accommodating or exposing the power connection end of the heating resistance wire 41; and the outer surface of the metal connecting base 3 is provided with an external thread structure 32 for threadedly mating with the sub-component connection notch 21 of the heat insulation sub-component 2. Tightening the thread can connect the metal sub-component 1 and the heat insulation sub-component 2 into one body, which is the most convenient for assembly and disassembly.

[0051] Optimally, the heat insulation layer 22 includes: a wood heat insulation layer 22.

[0052] The main material of the wood heat insulation layer 22 is wood. Wood has good heat preservation and insulation properties, which can facilitate direct manual holding of the heat insulation layer 22, thereby protecting the hand during cleaning and preventing hand burns.

[0053] Optimally, the scale structure 10 is a ruler.

[0054] The ruler has scales, which can facilitate the construction personnel to directly read the measurement results, facilitate data recording, and have low usage costs.

[0055] Optimally, the metal sub-component 1 is a stainless steel part.

[0056] The metal sub-component 1 made of stainless steel can utilize the heat conductivity of the metal and heat the surface of the metal sub-component 1 when the heating resistance wire 41 generates heat. At the same time, the stainless steel material can resist chemical corrosion media and is very suitable for detecting and storing the remaining depth of asphalt.
