Description

Technical Field

[0001] This utility model belongs to the technical field of refractory magnesia-carbon bricks, and in particular relates to a quality testing device for the production of refractory magnesia-carbon bricks. Background Technology

[0002] Refractory magnesia-carbon bricks are a type of non-burning carbon composite refractory material made primarily from high-melting-point alkaline oxide magnesium oxide (MgO) and high-melting-point carbon materials (such as graphite) that are difficult to wet by slag, with the addition of various non-oxide additives and bonded by carbonaceous binders.

[0003] As a key material in high-temperature industrial fields, refractory magnesia-carbon bricks have core performance indicators including mechanical properties such as room-temperature compressive strength and flexural strength, which ensure load-bearing capacity and resistance to damage. Compression testing machines simulate the stress state of materials under actual working conditions by applying vertical pressure, and can accurately measure parameters such as compressive strength and elastic modulus of materials. For magnesia-carbon bricks, this equipment can directly reflect their ability to resist compressive failure. During the use of the compression testing machine, the magnesia-carbon bricks are placed in the working area, and then pressure is applied through the pressure plate. If the magnesia-carbon bricks are damaged, they are prone to producing debris, which falls into the working area and is prone to splashing. The problem with the above technology is that it is not convenient to clean up the generated debris, and the protective effect is not good enough. Utility Model Content

To collect the scraped debris, the collection assembly 3 includes two cylinders 301, two mounting blocks 302, and a collection box 303. The rear sides of the two cylinders 301 are fixedly connected to the front side of the base 101.

The push rod 402 can drive the scraper 401 to move forward or backward. In order to fix it when the scraper 401 is not in use, the positioning assembly 5 includes two positioning rods 501, a pull rod 502, two tension springs 503, two horizontal plates 504 and two control rods 505. The surfaces of the two positioning rods 501 are respectively inserted into the interior of the two protective blocks 403. The bottom of the two positioning rods 501 is fixedly connected to the top of the pull rod 502. The front sides of the two horizontal plates 504 are respectively connected to the base. The rear side of 101 is fixedly connected. The tops of the two control rods 505 are fixedly connected to the bottoms of the two horizontal plates 504 respectively. The surfaces of the two control rods 505 are slidably connected to the left and right sides of the inside of the pull rod 502 respectively. Two tension springs 503 are respectively sleeved on the surfaces of the two control rods 505. The tops of the two tension springs 503 are fixedly connected to the bottoms of the two horizontal plates 504 respectively. The bottoms of the two tension springs 503 are fixedly connected to the tops of the pull rod 502. The two tension springs 503 play a fixing and rebounding role, so that the pull rod 502 and the two positioning rods 501 can automatically rebound to their original positions after movement.

In order to avoid the retraction Dust is generated inside the collection box 303 due to debris. The blocking component 6 includes a blocking plate 601, two movable blocks 602, two locking blocks 603, and two compression springs 604. The rear sides of the two locking blocks 603 are fixedly connected to the left and right sides of the front of the collection box 303, respectively. The interiors of the two movable blocks 602 are slidably connected to the surfaces of the two locking blocks 603, and the rear sides of both movable blocks 602 are fixedly connected to the front of the blocking plate 601. The bottom of the blocking plate 601 is slidably connected to the top plate of the collection box 303. The two compression springs 604 are respectively sleeved on the surfaces of the two locking blocks 603. The sides of the two compression springs 604 closest to the two locking blocks 603 are fixedly connected to the two locking blocks 603, and the rear sides of the two compression springs 604 are fixedly connected to the two locking blocks 603, respectively. The front of the movable block 602 is fixedly connected to two compression springs 604, which both serve to fix and rebound, allowing the blocking plate 601 and the two movable blocks 602 to automatically rebound to their original positions after movement. When the blocking plate 601 is opened, it can push the debris into the collection box 303; when closed, it seals the top of the collection box 303. To automatically open the blocking plate 601 during the scraping process, compression blocks 7 are fixedly connected to the left and right sides of the front of the scraper 401, and pushing blocks 8 are fixedly connected to the left and right sides of the top of the blocking plate 601. The movement of the scraper 401 will cause the two compression blocks 7 to move, which in turn will cause the two pushing blocks 8 to move, thereby causing the two pushing blocks 8 to move the blocking plate 601. To maintain the effectiveness of the two protective covers 202...Multiple baffles 201 are each fixedly connected to an anti-drop block 9. The surfaces of these anti-drop blocks 9 are slidably connected to and fitted against the opposite sides of the two protective covers 202. These anti-drop blocks 9 serve a limiting function, preventing the two protective covers 202 from moving back and forth when the two protective blocks are inserted into the baffles 201.

[0018] The working principle of this utility model: When testing magnesia-carbon bricks, the bricks are placed on top of the base 101. The controller 102 then moves the lifting member 104 downwards via two connecting pillars 103, causing the pressure plate 105 to move downwards. During this downward movement, the two protective covers 202 and two connecting blocks 203 also move downwards due to their own weight. The two protective covers 202 are then connected to multiple baffles 201. The bottom of the pressure plate 105 applies a compression test to the top of the magnesia-carbon bricks. After the test, the lifting member 104 moves the pressure plate 105 upwards. The lifting member 104 then moves the two connecting blocks 203 upwards via two protruding pillars 204, causing the two protective covers 202 to move upwards and disengage from the baffles 201. The magnesia-carbon bricks are then removed. When it is necessary to clean debris from the top of the base 101, the pull rod 502 is pushed downwards, causing the two positioning rods 501 to move downwards. At this time, the push rod 402 can be pushed to drive the scraper. Plate 401 moves forward, push rod 402 moves stably via moving block 404 and limiting block 405, scraper 401 pushes the debris on top of base 101 forward, and drives two squeezing blocks 7 to move. The two squeezing blocks 7 squeeze the two pushing blocks 8, causing the two pushing blocks 8 to drive the blocking plate 601 forward, thereby pushing the debris into the collection box 303. The blocking plate 601 drives the two movable blocks 602 to move, and causes the two squeezing springs 604 to deform. When the push rod 402 drives the scraper 401 back to its original position, the blocking plate 601 and the two movable blocks 602 will return to their original positions through the two compression springs 604 to block the top of the collection box 303. The movement of the pull rod 502 will cause the two tension springs 503 to deform. When the two movable blocks 602 return to their original positions, the pull rod 502 is released. The pull rod 502 drives the two positioning rods 501 to insert into the interior of the two protective blocks 403 through the two tension springs 503, thereby fixing the push rod 402 and the scraper 401.
