Description

Technical Field

[0001] This utility model relates to the field of refractory brick production technology, specifically to a pressure resistance testing device for the production of heat-insulating refractory bricks. Background Technology

[0002] Refractory bricks are shaped refractory materials with standard and regular shapes. They can also be temporarily processed as needed during construction. Refractory bricks are also called fire bricks. They are refractory materials made by firing refractory clay or other refractory raw materials. They are light yellow or brownish and are mainly used for lining smelting furnaces. The pressure resistance of heat-insulating refractory bricks needs to be tested during production.

[0003] The prior art patent document CN211660520U provides a pressure resistance testing device for refractory brick production, including a transmission platform. The platform transports processed refractory bricks to a designated storage location. When a refractory brick reaches the lower part of a pressure sensor, a third cylinder is controlled to move downwards, allowing the pressure sensor to perform pressure resistance testing on each brick. This automatic testing improves accuracy. A second cylinder controls grippers to pick up defective refractory bricks, while a first cylinder moves an upward mounting plate, further lifting the grippers. A sliding mechanism moves the first cylinder towards a collection box, collecting the defective bricks. This automatic sorting of defective products significantly reduces labor costs and improves efficiency.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the conveyor platform transports refractory bricks for testing, and the pressure test takes time. When multiple refractory bricks are placed at the same time, the inconsistent spacing between adjacent refractory bricks can easily affect the test, resulting in low production efficiency. Secondly, during the use of the device, unqualified refractory bricks are prone to breakage during the pressure test, and they are also prone to breakage during clamping, which affects cleaning and transfer. Improvements are needed. In view of this, we propose a pressure testing device for the production of heat-insulating refractory bricks. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues raised above regarding the time required for pressure testing when transporting refractory bricks via a transmission platform, the inconsistent spacing between adjacent refractory bricks when multiple bricks are placed simultaneously, which can affect testing efficiency, and the tendency for substandard refractory bricks to crack during pressure testing and break apart during clamping, thus hindering cleaning and transfer, this utility model is proposed.

A rotating shaft rotatably connected to the side wall of the first fixed frame is located on the inner circumference of the first gear. Baffles are provided on the outer circumference of the rotating shaft. A fixed platform is located at one end of the conveying device, a collection trough on its side wall, and a waste trough on its other side wall. A second fixed frame is located at the top of the collection trough, and a sorting component is located at the top of the second fixed frame. A cylinder is located on one side of the top of the second fixed frame, and a pressure sensor is located at the output end of the cylinder. The first motor is electrically connected to an external power source, and the cylinder is connected to an external air pump via an air pipe. The pressure sensor is positioned at the top of the fixed platform to prevent the refractory bricks from shifting during pressure resistance testing, thus avoiding affecting the testing accuracy.

[0012] In a preferred embodiment of the pressure resistance testing device for producing heat-insulating refractory bricks according to this utility model, the sorting assembly includes a second motor. A second gear is provided on the outer circumference of the output end of the second motor. A toothed plate meshes with the bottom of the second gear. Connecting rods are provided at both ends of the bottom of the toothed plate. Push plates are provided at the bottom of both connecting rods. Limiting grooves are provided at both ends of the top of the second fixing frame. The second motor is electrically connected to an external power source. The limiting grooves restrict the movement of the connecting rods, preventing the toothed plate from shifting and disengaging from the second gear.

[0013] In a preferred embodiment of the pressure resistance testing device for producing heat-insulating refractory bricks according to this utility model, a fixed cover is provided on the outer circumference of the cylinder output end, and multiple springs are provided in the inner cavity of the side wall of the fixed cover. A protective cover is provided at the bottom of the springs. The protective cover facilitates shielding and prevents dust from the heat-insulating refractory bricks from causing contamination during the pressure resistance test.

[0014] In a preferred embodiment of the pressure resistance testing device for producing heat-insulating refractory bricks according to this utility model, the height of the fixed platform matches the height of the top of the conveying device, and the position of the pressure sensor matches the position of the top edge of the fixed platform.

[0015] In a preferred embodiment of the pressure resistance testing device for the production of heat-insulating refractory bricks according to this utility model, the inner cavity height of the fixed frame is greater than the rotation diameter of the baffle, and the number of teeth of the toothed ring matches the number of teeth of the first gear.

[0017] As a preferred embodiment of the pressure resistance testing device for the production of heat-insulating refractory bricks according to this utility model, the side wall of the inner cavity of the collection tank near the fixed platform is inclined, and the size and position of the two push plates are respectively matched with the size and position of the collection tank and the waste tank.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This pressure testing device for the production of heat-insulating refractory bricks involves starting a conveyor to transport the heat-insulating refractory bricks, opening a cylinder to drive a pressure sensor to press down and test the pressure resistance of the refractory bricks, and intermittently rotating a separating component to separate the refractory bricks, so that the refractory bricks are transported one at a time for pressure testing, preventing the transport of refractory bricks from interfering with the previous refractory bricks that have not yet completed the pressure test, thus effectively improving the testing efficiency.

[0021] This pressure testing device for the production of heat-insulating refractory bricks starts by activating a second motor, which rotates a second gear and moves a toothed plate. This causes two connecting rods to move two push plates simultaneously to sort the heat-insulating refractory bricks. Qualified refractory bricks are pushed into the collection trough, while unqualified refractory bricks are pushed into the waste trough, thus preventing broken refractory bricks from being difficult to pick up.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a pressure resistance testing device for the production of heat-insulating refractory bricks, including:

[0035] Please see Figures 1-5This embodiment of a pressure-resistant testing device for producing heat-insulating refractory bricks includes a conveying device 1. A first fixed frame 2 is welded to the top of the conveying device 1. A separating component 3 is welded to the side wall of the first fixed frame 2. The separating component 3 includes a fixed frame 301. A first motor 302 is threadedly connected to the side wall of the fixed frame 301. A turntable 303 is interference-fitted to the output end of the first motor 302. A gear ring 304 is welded to the side wall of the turntable 303. A first gear 305 meshes with the inner circumference of the gear ring 304. The first motor 302 drives the gear ring 304 on the side wall of the turntable 303 to rotate, causing... The first gear 305 rotates intermittently. A rotating shaft 306, rotatably connected to the side wall of the first fixed frame 2, is welded to the inner circumference of the first gear 305. Baffles 307 are welded to the outer circumference of the rotating shaft 306. Through the rotating shaft 306 and the baffles 307, the refractory bricks are separated to maintain consistent spacing. A fixed platform 4 is welded to one end of the conveying device 1. A collection trough 5 is welded to the side wall of the fixed platform 4 to collect qualified refractory bricks. A waste trough 6 is welded to the other side wall of the fixed platform 4 to collect unqualified refractory bricks. A [missing information - likely a design feature] is welded to the top of the collection trough 5. The second fixed frame 7 has a sorting component 8 threadedly connected to its top. A cylinder 9 is threadedly connected to one side of the top of the second fixed frame 7, and a pressure sensor 10 is threadedly connected to the output end of the cylinder 9. The pressure sensor 10 is used to detect the pressure of the refractory bricks when the cylinder 9 is pressed down. The first motor 302 is electrically connected to an external power source. The cylinder 9 is connected to an external air pump via an air pipe. Multiple insulating refractory bricks are laid in a single row at one end of the top of the conveying device 1. The conveying device 1 is started to transport the insulating refractory bricks to the top of the fixed platform 4, ensuring the spacing between the refractory bricks remains consistent to prevent the previous one from being moved. When the pressure resistance test of a refractory brick is not completed, the next refractory brick is directly conveyed to the position of the previous refractory brick, interfering with the pressure resistance test. Automatic separation is more time-saving and labor-saving, effectively improving the testing efficiency. The fixed frame 301 is convenient for protection, preventing dust and impurities from entering and affecting the meshing of the gear ring 304 and the first gear 305. By controlling the speed of the first motor 302 and the conveying speed of the conveying device 1, it is easy to ensure that one refractory brick is conveyed for pressure resistance testing at one interval. The conveying device 1 is existing technology, which can be directly referred to in patent number CN221051562U, and will not be described in detail here.

[0036] It is worth noting that, in order to facilitate sorting and prevent broken refractory bricks from being difficult to pick up, the sorting component 8 specifically includes a second motor 801. A second gear 802 is interference-fitted onto the outer circumference of the output end of the second motor 801. A toothed plate 803 meshes with the bottom of the second gear 802. The second gear 802 is used to drive the toothed plate 803 to move in different directions. Connecting rods 804 are welded to both ends of the bottom of the toothed plate 803. Push plates 805 are welded to the bottom of both connecting rods 804. Push plates 805 are used to push the inspected refractory bricks for sorting. Limiting grooves 806 are opened at both ends of the top of the second fixing frame 7. The limiting grooves 806 limit the movement direction of the connecting rods 804. The second motor 801 is electrically connected to an external power source. The two push plates 805 move simultaneously to prevent the other push plate 805 from obstructing the movement of refractory bricks when one push plate 805 is sorting them, thus facilitating use.

[0037] Next, to prevent refractory brick fragments from flying and injuring workers, a fixed cover 11 is interference-fitted to the outer circumference of the output end of the cylinder 9. Multiple springs 12 are welded to the inner cavity of the side wall of the fixed cover 11, and a protective cover 13 is welded to the bottom of the springs 12. The cylinder 9 drives the pressure sensor 10 to press down and simultaneously moves the fixed cover 11 downward, so that when the bottom of the protective cover 13 contacts the top of the fixed platform 4, it retracts. The rebound force of the springs 12 drives the protective cover 13 to press down and press against the fixed platform 4, which facilitates the protection of the refractory bricks during the pressure test and avoids the flying fragments of broken refractory bricks from injuring workers.

[0038] Meanwhile, in order to facilitate the pressure resistance test of the heat-insulating refractory bricks, the height of the fixed platform 4 is matched with the height of the top of the conveying device 1, and the position of the pressure sensor 10 is matched with the position of the top edge of the fixed platform 4. By using the fixed platform 4 with the height of the top of the conveying device 1, the heat-insulating refractory bricks on the top of the conveying device 1 can be directly transported to the top of the fixed platform 4 for pressure resistance test.

[0039] Furthermore, to facilitate the intermittent rotation of the baffle 307, specifically, the inner cavity height of the fixed frame 301 is greater than the rotation diameter of the baffle 307, and the number of teeth of the gear ring 304 matches the number of teeth of the first gear 305. The fixed frame 301, with its inner cavity height greater than the rotation diameter of the baffle 307, avoids obstructing the rotation of the baffle 307. The gear ring 304, with its number of teeth matching that of the first gear 305, facilitates the intermittent rotation of the first gear 305 while allowing it to rotate one revolution at a time.

[0040] It is worth noting that, in order to improve stability, the bottom of the toothed plate 803 is slidably connected to the top of the second fixed frame 7, and the size and position of the limiting groove 806 are matched with the size and position of the connecting rod 804. By using the limiting groove 806 that matches the size and position of the connecting rod 804, the influence of the connecting rod 804 is limited, making the push plate 805 move more smoothly.

[0041] Finally, to prevent qualified heat-insulating refractory bricks from being broken, specifically, the side wall of the inner cavity of the collection tank 5 near the fixed platform 4 is inclined, and the size and position of the two push plates 805 are matched with the size and position of the collection tank 5 and the waste tank 6, respectively. Through the inclined side wall of the inner cavity of the collection tank 5, qualified heat-insulating refractory bricks can slide down the inclined surface for collection, avoiding the heat-insulating refractory bricks from falling and breaking directly.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] First motor 302: Y90S-2;

[0045] Second motor 801: Z90S-2;

[0046] Cylinder 9: CA2Y-Z40.

[0047] Combination Figures 1-5 The pressure resistance testing device for producing heat-insulating refractory bricks according to this embodiment is used in the following specific process:

[0048] 1: When this device is needed for pressure testing in the production of heat-insulating refractory bricks, multiple heat-insulating refractory bricks are laid in a single row at one end of the top of the conveying device 1. The conveying device 1 is started to transport the heat-insulating refractory bricks to the top of the fixed platform 4. The first motor 302 is started to make the gear ring 304 on the side wall of the turntable 303 rotate, which drives the first gear 305 to rotate. This causes the rotating shaft 306 to drive the baffle 307 to rotate intermittently to separate the refractory bricks and keep the spacing of the refractory bricks consistent. The cylinder 9 is started to drive the pressure sensor 10 to press down cyclically to test the pressure resistance of the refractory bricks.

[0049] 2: When the pressure sensor 10 detects a qualified refractory brick, it controls the second motor 801 to make the second gear 802 rotate and drive the toothed plate 803 to move, so that the two connecting rods 804 drive the two push plates 805 to move simultaneously and push the refractory brick into the collection tank 5. When a defective refractory brick is detected, it controls the second motor 801 to rotate in the opposite direction and push the push plate 805 to push the refractory brick into the waste tank 6.

[0050] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.

Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
