Description

Technical Field

[0001] The present application relates to the technical field of asphalt testing instruments, and in particular to a detachable thermal insulation asphalt testing casting mold instrument. Background Art

[0002] Asphalt is a main material for road and bridge pavement and can be used for various road and bridge surface layers. In highway and water transport testing, asphalt is the main test object, and its softening point, penetration, elongation and other parameters need to be tested. Preparing test samples before testing is a very important step. The pouring of samples affects the success and accuracy of the test. At present, most of the pouring instruments for preparing test samples are simple tools such as beakers, which are difficult to pour and have no heat preservation. The temperature of asphalt needs to be repeatedly heated, which is easy to cause aging and seriously affect the test results. Heated asphalt will cause risks such as burns to the tester, which is a safety hazard.

[0003] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the application and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in the field. Summary of the invention

[0004] The utility model aims to provide a detachable heat-insulating asphalt test casting mold instrument, which can slow down the cooling speed of asphalt and conveniently control the flow rate of asphalt.

[0005] In order to achieve the above objectives, this application is implemented by adopting the following technical solutions:

[0006] A detachable insulated asphalt test casting mold instrument includes a glass container and an insulated metal shell, wherein the glass container is detachably installed inside the insulated metal shell, wherein the insulated metal shell includes a shell body, wherein the inner wall of the shell body is provided with double-sided aluminum film insulation cotton, a flow control plate is provided at the outlet below the shell body, and a switch control valve for controlling the movement of the flow control plate is provided on the side wall of the shell body.

[0007] Optionally, an asphalt outflow outlet is provided below the glass container.

[0008] Optionally, a glass cover is provided on the top of the shell body, and a ventilation hole is provided above the glass cover.

[0009] Optionally, the flow control sheet is connected to the switch control valve via a copper strip.

[0010] Optionally, the switch control valve is a spiral rod.

[0011] Optionally, the asphalt flow outlet of the glass container protrudes from the outlet below the shell body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The detachable glass container can be directly installed after heating to save the process and time of pouring asphalt, and the double-sided aluminum film insulation cotton can be used to slow down the cooling speed of asphalt;

[0014] The flow rate of asphalt is controlled by the flow control sheet, which allows better control during mold casting. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example

[0021] A detachable thermal insulation asphalt test casting mold instrument, such as Figure 1 and Figure 2As shown, it includes a glass container 1 and an insulating metal shell. The glass container 1 can be detachably installed inside the insulating metal shell. The insulating metal shell includes a shell body 5. The inner wall of the shell body 5 is provided with double-sided aluminum film insulation cotton 6. A flow control plate 7 is provided at the outlet below the shell body 5. The side wall of the shell body 5 is provided with a switch control valve 8 for controlling the movement of the flow control plate 7. The glass container 1 is detachable. When the asphalt temperature is not enough, the glass container 1 can be directly removed and placed in an oven to be heated to the same temperature as the asphalt. Then, it is loaded into the instrument with crucible tongs, which saves time for processing the asphalt and avoids the asphalt from cooling too quickly. The double-sided aluminum film insulation cotton 6 plays a role of heat preservation, and the flow control plate 7 controls the asphalt flow to facilitate molding.

[0022] like Figure 2 As shown, an asphalt outflow outlet 2 is arranged at the bottom of the glass container 1, and the glass container 1 stores asphalt.

[0023] like Figure 1 As shown, a glass cover 3 is provided on the top of the shell body 5, and a vent hole 4 is provided above the glass cover 3 to keep the internal and external air pressures of the instrument consistent and ensure the asphalt outflow speed.

[0024] like Figure 1 As shown, the glass container 1 is a combination of a cylinder and a cone with a diameter of 60 mm and a height of 120 mm.

[0025] like Figure 1 As shown, the shell body 5 is a cylinder and a cone with a diameter of 65 mm, a height of 100 mm, and a wall thickness of 1 mm. The shell body 5 is made of copper, which protects the instrument and is easy to clean. Example

[0026] like Figure 1 As shown, the flow control sheet 7 is connected to the switch control valve 8 through a copper strip to control the outlet size so as to control the flow rate of the asphalt.

[0027] like Figure 1 As shown, the switch control valve 8 is a spiral rod with a diameter of 10 mm, and the flow control plate 7 is rotated to move close to the asphalt flow outlet 2.
