Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to an experimental device for measuring the bulk density of green coke of needle coke. Background Art

[0002] Needle coke is a high-quality material for producing high-power and ultra-high power electrodes, special carbon materials, carbon fibers and their composite materials and other high-end carbon products. Its stacking density has a huge impact on production efficiency and product quality. Therefore, accurate measurement of the stacking density of needle coke is crucial for production management. The current needle coke stacking density test methods on the market have disadvantages such as complexity, high cost and difficulty in operation.

[0003] The existing device for measuring the bulk density of needle coke green coke usually requires placing the green coke block into a sealed bag, extracting the air in the sealed bag, forming a vacuum state, and placing the bag into a water bucket for testing. During the process of extracting the air, a vacuum sealing machine is required.

[0004] When an existing vacuum sealing machine is used to seal a sealing bag, the operator usually manually fixes the sealing bag. However, the manual fixing method is very likely to cause the sealing bag to shift due to hand shaking during the sealing process, resulting in failure to extract the air. At the same time, due to the irregular shape and hard texture of the coke blocks, they may move in the sealing bag due to changes in internal pressure during the vacuuming process, thus affecting the sealing effect and may even damage the sealing bag or cause a loose seal. To address this problem, we proposed an experimental device for measuring the bulk density of green coke from needle coke. Summary of the invention

[0029] In the utility model, when in use, block coke with a mass range of 500g-2000g is randomly selected from the tower coke material pile. When selecting block coke, try to select slender, flat and smooth ones without too many bubbles in the block coke. If there are edges and corners, it is necessary to use a sampling shovel or a putty knife to smooth the edges and corners. After trimming, the mass of the block coke is weighed with an electronic balance and put into a vacuum bag. The vacuum bag is then placed on the surface of the placement plate 5. After placement, the electric push rod 771 in the fixed frame 6 is driven, and the electric push rod 771 pushes the fixed frame 772 to move downward.
