Description

Technical Field

[0001] The invention relates to the technical field of physical property detection of substrate glass powder, and in particular to a device and method for detecting the bulk density of a glass batch material. Background Art

[0002] As one of the key components of display devices, substrate glass directly affects the display's performance indicators such as resolution, transmittance and viewing angle. During the production process of substrate glass, the glass batch is a combination of multiple raw materials. The stacking density of the batch directly affects the fluidity, stability and uniformity of the powder, and thus directly affects the efficiency of the raw materials being fed from the feeder to the furnace, as well as the stability of the pile state formed when the raw materials are fed into the kiln, affecting the melting efficiency of the raw materials.

[0003] In the existing technology, the test of the bulk density of powders is based on the funnel method. The powder is naturally poured into the funnel, and the valve at the bottom of the funnel is opened to allow the powder to flow into and fill a fixed-volume cylindrical cup with a known density. The bulk density of the powder is obtained by (total mass-cylindrical cup mass) / cylindrical cup volume. However, the process of the powder filling the cylindrical cup from the funnel is easily affected by the powder particle size and the aperture of the bottom of the funnel, which may result in poor powder fluidity or blockage of the aperture at the bottom of the funnel. In addition, the accumulation state of the powder is also easily affected by the position or height of the powder pouring, and there are too many human interference factors. Summary of the invention

[0004] The purpose of the present invention is to provide a device and method for detecting the bulk density of glass batch materials, so as to overcome the problems existing in the prior art. The present invention can pre-treat the powder by the spiral axial motion of the spiral impeller, eliminate the differences between the batch material particles, eliminate the influence of uneven particle size on the natural bulk density, avoid the blockage of the funnel when the powder naturally flows into the cylindrical cup, and improve the detection efficiency; it can also avoid the influence of artificial addition of materials on the natural bulk state of the powder, and improve the detection accuracy of the natural bulk density.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A device for detecting the bulk density of glass batch materials comprises a main body support, a control mechanism is installed on the main body support, a propeller is installed at the bottom of the control mechanism, a weighing device is installed at the bottom of the main body support, a constant volume container is arranged on the weighing device, a cutting container is connected to the top of the constant volume container through a cutter, the weighing device is connected to a data processing system, and a data recording button is arranged on the data processing system; Furthermore, the main body support includes a vertical support, a horizontal support is installed at the bottom of the vertical support, the control mechanism is installed on the side of the vertical support, and the weighing device is installed on the horizontal support; Furthermore, the cutting container can be rotated 180° around the busbar by a cutter.

[0006] A method for detecting the bulk density of a glass batch material, based on the above-mentioned device for detecting the bulk density of a glass batch material, comprises the following steps: (1) Start the detection device, reset the weighing device to zero, and set the volume and diameter of the constant volume container, the diameter of the cutting container, the rotation speed of the propeller, and the speed of the axial reciprocating motion in the data processing system; (2) Pour the glass batch material to be tested into a constant volume container, pre-treat the glass batch material to be tested, and then confirm the volume of the glass batch material to be tested; (3) Weighing and recording the mass data of the glass batch to be tested by a weighing device, and transmitting the mass data to a data processing system; (4) The data processing system calculates the bulk density of the glass batch material to be tested based on the volume data obtained in (2) and the mass data obtained in (3); Furthermore, the volume of the constant volume container in (1) is 10-200 mL, and the diameters of the constant volume container and the cutting container are equal, both of which are 20-60 mm; Furthermore, the rotation speed of the propeller in (1) is 10-150 rpm, and the speed of the axial reciprocating motion is 10-50 mm / s; Furthermore, the pre-processing in (2) is specifically as follows: starting the control mechanism, the propeller starts to rotate from the starting position, and performs axial reciprocating spiral motion from top to bottom 3-5 times, and then rises to the starting position; Furthermore, the confirmation of the volume of the glass batch material to be tested in (2) is specifically as follows: brushing off the glass batch material to be tested remaining on the propeller, and rotating the divider to make the container opening of the constant volume container be filled with the glass batch material to be tested; Furthermore, the recording in (3) is specifically: clicking a data recording button on the data processing system; Furthermore, the calculation formula in (4) is: ; In the formula, ρ is the bulk density of the glass batch to be tested, m is the mass of the glass batch to be tested, and V is the volume of the glass batch to be tested.

[0007] The above technical solution has the following advantages or beneficial effects: The present invention provides a device for detecting the bulk density of glass batch materials, which drives a screw blade through a control mechanism to convey and mix materials, and simultaneously utilizes a weighing device and a data processing system to realize automatic measurement of quality and automatic recording of data, thereby greatly improving the degree of automation of detection and reducing the tediousness and errors of manual operation; a divider and a dividing container are used to help realize a more uniform distribution of materials, thereby further improving the accuracy of measurement; the data recorded by the data processing system is traceable, and a user can conveniently query and compare the detection results of different batches or under different conditions, thereby providing strong support for quality control and process optimization in the production process.

[0008] Furthermore, the vertical bracket provides sufficient support to ensure that the control mechanism and the propeller can operate smoothly, while the horizontal bracket ensures the stability and accuracy of the weighing device and avoids measurement errors caused by shaking or tilting.

[0009] Furthermore, by rotating the cut container 180° around the busbar, the detection volume can be accurate, further improving the accuracy of the detection.

[0010] The present invention also provides a method for detecting the bulk density of glass batch materials. By accurately setting the volume and diameter of the fixed volume container, the diameter of the cutting container, and the rotation speed and axial reciprocating speed of the spiral blade, the consistency of various parameters in the detection process can be ensured, thereby improving the accuracy and reliability of bulk density detection, reducing errors caused by improper operation or equipment differences, and making the detection results more accurate; the glass batch materials to be tested are pre-treated by the spiral axial movement of the spiral blade, and this step effectively eliminates the differences between the batch material particles, especially the problem of uneven particle size. In the traditional detection method, the powder material is easy to block the funnel when it naturally flows into the cylindrical cup, which not only affects the detection efficiency, but also may affect the detection results due to the uneven accumulation of the powder material caused by the blockage. However, through the present invention, even if the particle size distribution of the original batch material is relatively wide, it can be achieved to a relatively uniform state through pretreatment, thereby avoiding the influence of particle size differences on the natural stacking density detection results, and significantly improving the accuracy of stacking density detection; the data processing system is used to receive and process quality data and calculate stacking density in real time, thereby realizing the automation of the detection process, which not only reduces the tediousness of manual operation, but also improves the detection efficiency and greatly simplifies the operation process; this method is suitable for the detection of stacking density of different types of glass batch materials, and can adapt to the characteristics and detection requirements of different batch materials by adjusting the parameters in the detection device and the data processing system. At the same time, since the quality data and calculation results are stored in the data processing system, historical data can be easily traced and analyzed.

[0011] Furthermore, by setting the capacity of the fixed volume container and the diameters of the fixed volume container and the cutting container to be equal, it can be ensured that the container size used for each test is consistent, thereby improving the standardization of the test results.

[0012] Furthermore, the rotation speed and axial reciprocating speed of the propeller are key factors affecting the pretreatment effect. By setting a reasonable speed range, it can be ensured that the propeller can effectively stir and mix the glass batch, thereby eliminating the differences between particles and improving the detection accuracy of the bulk density.

[0013] Furthermore, the rotating divider allows the container mouth to be filled with the glass batch material to be tested, which can ensure the accuracy of the measured volume and ensure that the test result is more accurate.

[0014] Furthermore, by clicking the data record button on the data processing system, accurate recording of the data can be ensured, while making the data traceable, facilitating subsequent data management and query. BRIEF DESCRIPTION OF THE DRAWINGS
