Description

An overflow water tank for the test of the basket method

technical field

The utility model belongs to the technical field of test instruments or equipment for testing the characteristics of asphalt mixture in road materials, and in particular relates to an overflow water tank for test of the net basket method.

Background technique

The overflow water tank for the basket method test is one of the instruments used to measure the apparent relative density and apparent density of asphalt mixture specimens. The running water tank must include the following functions: (1) Set up a water level overflow device to keep the water level of the specimen and the basket immersed in water; (2) The test temperature must be controlled at 25°C ± 0.5°C. However, due to the fixed water capacity of the overflow water tank during the test, part of the water will be taken away after each test piece is tested, resulting in a drop in the water level of the water tank. If the specimen is placed too deep, it will easily cause the water level to overflow the water tank. If the specimen is placed too shallow, it will easily cause the specimen to stick to the wall of the basket during the descent process, which will affect the accuracy of the test. In addition, the commonly used overflow water tank relies on the water valve to control the water level. , the water flow rate is slow, the test efficiency is low, and the commonly used overflow water tank is generally not provided with insulation and heating measures. When the test is carried out in cold winter areas, because the water density in the water tank is greatly changed by the temperature, it is easy to lead to poor test consistency. . Therefore, it is necessary to redevelop the overflow water tank for the basket method test with simple operation and accurate measurement in view of the shortcomings of the overflow water tank required by the code.

Utility model content

The purpose of this utility model is to provide an overflow water tank for the test of the basket method in view of the shortcomings of the existing overflow water tank. When using this instrument, the test efficiency is high, and the water storage of the auxiliary water tank can omit the step of adding water for each test. , the water flow will not overflow the main water tank, and the water level can be effectively controlled to ensure the accuracy of the test. It is convenient for the operator to take the test piece and save water resources. The auxiliary water tank is equipped with a heating and stirring device to ensure that the test water temperature is constant, and Heating the water temperature in the auxiliary water tank can avoid the test data fluctuation caused by the water flow fluctuation caused by the direct heating and stirring in the main water tank.

In order to realize the above-mentioned purpose of the invention, the present invention adopts following technical scheme:

An overflow water tank for a basket method test, mainly composed of a main water tank part and an auxiliary water tank part, the main water tank part mainly includes an electronic balance, a main water tank and a main water tank cap, and the auxiliary water tank part mainly includes an auxiliary water tank, The supporting platform of the auxiliary water tank and the bearing platform of bolts, the main water tank and the auxiliary water tank are connected by rubber hoses to form a whole.

The water level line is marked on the outer wall of the main water tank.

The auxiliary water tank is equipped with a heating and stirring device and a temperature digital display meter.

The auxiliary water tank cap and the bolt cap are connected as a whole through cap adjusting bolts.

Compared with the prior art, the utility model has the advantages of:

When using this instrument, using the principle of the connector, the water storage in the auxiliary water tank can omit the steps of adding water for each test, and the water flow will not overflow the main water tank, which is convenient for the operator to take the test piece, saves water resources, is green and environmentally friendly, and is heated by the auxiliary water tank It can avoid the fluctuation of test data caused by direct heating and stirring in the main water tank.

Detailed ways

The technical solution of the utility model will be described in further non-limiting detail below in conjunction with the embodiments and accompanying drawings.

One, the basic structure of a kind of basket method test overflow water tank:

As shown in Figure 1 and Figure 2, an overflow water tank for the basket method test is mainly composed of a main water tank part and an auxiliary water tank part, and the main water tank part mainly includes an electronic balance 1, a main water tank 4 and a main water tank cap 6. The auxiliary water tank part mainly includes the auxiliary water tank 8, the auxiliary water tank cap 9 and the bolt cap 10, the main water tank 4 and the auxiliary water tank 8 are connected by a rubber hose 13 to form a whole; the outer wall of the main water tank 4 is marked with The water level line; the inside of the auxiliary water tank 8 is provided with a heating and stirring device 11 and a temperature digital display meter 12;

Two, a method of using the overflow water tank for the basket method test:

1. Turn on the heating and stirring device 11, so that the temperature of the temperature digital display meter 12 is at 25±0.5°C.

2. Put the dry test piece on the electronic balance 1 and weigh the mass m ₁ in the air.

3. Hang the net basket 5, adjust the cap adjustment bolt 7 to make the water level of the main water tank 4 reach the standard scale, reset the electronic balance 1, adjust the cap adjustment bolt 7 so that the water level of the main water tank is on the bottom of the net basket, and place the test piece on In the net basket 5, adjust the cap adjusting bolt 7 to make the water level of the main water tank reach the standard scale, and weigh the mass m _w in the water.

4. After recording the test data, adjust the bearing platform adjustment bolt 7 to lower the water level of the main water tank 4 to a position convenient for the test personnel to take out the test piece, and take out the test piece.

5. Repeat steps 1-4 above until the end of the test.
