Description

Technical Field

[0001] The present invention relates to the field of physical detection technology, and in particular to a graphite crucible detection device. Background Art

[0002] In industrial production, graphite crucibles are widely used. In the metallurgical industry, it is widely used as a refractory material in furnaces for smelting metals. It can withstand extremely high temperatures and chemical erosion, and is an indispensable key component in smelting processes such as steelmaking, aluminum smelting, and copper smelting. In addition, in the ceramic industry, graphite crucibles are also often used as kiln materials for firing ceramic products. Their high strength and corrosion resistance ensure the high-quality production of ceramic products. Given that graphite crucibles work under high temperature, high pressure and corrosive environments, their quality has a vital impact on the accuracy, safety and efficiency of experimental or production results. Therefore, it is of great significance to conduct strict testing of graphite crucibles to detect whether there are defects such as cracks and breakages in the graphite crucibles to prevent safety accidents such as explosions or leaks during use.

[0003] In the patent entitled "A graphite crucible detection device" and the publication number CN117233028B, it is proposed that during the monitoring process, the existing detection device places the crucible in a water flow, and the water flow seeps out from the cracks, thereby realizing the detection of the cracks in the crucible. However, it is difficult for the detection device to detect whether the mass distribution of the crucible is uniform during the detection process. The detection device compresses four second telescopic rods and makes the stop blocks on the four second telescopic rods stop against the inner wall of the graphite crucible to be detected respectively, and makes the four second telescopic rods be located at the same position in the graphite crucible. Height, after the graphite crucible is stable, by observing the data detected by the four third sensors, it can be determined whether the mass distribution of the graphite crucible is uniform. However, it is impossible to perform a large-area detection on the inner wall of the graphite crucible during the detection process, and only a single-point small-range detection can be performed. The inner wall of the graphite crucible will have different degrees of depression and uneven mass distribution. In the case of a single-point small-range detection, the detection time is long, and in the production process of the graphite crucible, cracks will not necessarily appear at the uneven mass. Therefore, a graphite crucible detection device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Figure 1-Figure 5As shown, the present application is a graphite crucible detection device, including a water tank 100, the outside of the water tank 100 is fixedly connected to a lifting structure, a connecting plate 101 is installed on the lifting structure, a sliding groove 102 is provided inside the connecting plate 101, a sliding plate 103 is slidably connected inside the sliding groove 102, a positioning connection seat 104 is fixedly connected to the outside of the sliding plate 103, an L-shaped connection seat 105 is fixedly connected to the outside of the positioning connection seat 104, a plurality of support rods 106 are fixedly connected to the outer wall of the L-shaped connection seat 105 and the sliding plate 103, and a sleeve rod 107 is sleeved on the outside of the support rod 106, which is located at the sliding The movable plate 103 and the external support rod 106 of the L-shaped connecting seat 105 are fixedly connected to the end close to each other with a pressure sensor 110, and the outside of the pressure sensor 110 is fixedly connected with a support spring 109, the inside of the sleeve rod 107 is slidably connected with a top pressure plate 111, and a limiting groove 112 is provided inside the sleeve rod 107, and the top pressure plate 111 is slidably connected to the inside of the limiting groove 112, and a rolling wheel 108 is installed on the outside of the top pressure plate 111, and the end of the support spring 109 away from the pressure sensor 110 is fixedly connected to the outer wall of the top pressure plate 111, and a supporting rotating structure is installed at the bottom of the connecting plate 101.

[0029] Specifically, during use, the staff can move the connecting plate 101 above the water tank 100 by starting the lifting structure, and place the graphite crucible on the connecting plate 101, and use the supporting rotating structure to support the graphite crucible. After using the supporting rotating structure to support the graphite crucible, the staff can drive the L-shaped connecting seat 105 to move to the outside of the graphite crucible by holding the sliding plate 103, and fit the multiple support rods 106 and sleeve rods 107 located on the outside of the L-shaped connecting seat 105 to the inner wall of the graphite crucible, and fit the multiple support rods 106 and sleeve rods 107 connected to the outer wall of the sliding plate 103 to the outer wall of the graphite crucible. After the multiple support rods 106 and the multiple sleeve rods 107 are fitted to the outer wall and inner wall of the graphite crucible, the staff can start the supporting rotating structure to drive the graphite crucible to rotate on the connecting plate 101. During the rotation on the graphite crucible 1, the multiple support rods 106 and the sleeve rod 107 will cooperate with the multiple rolling wheels 108 to monitor the inner wall and the outer wall of the graphite crucible. The rolling wheels 108 can assist the support rods 106 and the sleeve rod 107 to move in a circular shape on the inner wall of the graphite crucible. In the process of movement, when the inner wall or the outer wall of the graphite crucible appears uneven, the rolling wheels 108 will first contact the uneven position. When the rolling wheels 108 contact the uneven position, the rolling wheels 108 will drive the top pressure plate 111 to move inside the sleeve rod 107. Once the top pressure plate 111 slides inside the sleeve rod 107, the support spring 109 connected to the top pressure plate 111 will be squeezed by the top pressure plate 111 to produce deformation. In the case of deformation, the pressure sensor 110 located at the rear can be used to monitor the unevenness and uneven quality inside the graphite crucible.

[0030] Furthermore, during use, the plurality of support rods 106 and sleeve rods 107 simultaneously detect the inner wall and the outer wall of the graphite crucible, and during the detection process, the graphite crucible only needs to be rotated to perform a comprehensive detection on the inner wall and the outer wall of the graphite crucible.

[0031] like Figure 2 As shown, the lifting device includes a support frame 500, the internal rotation of the support frame 500 is connected to a threaded rod 502, the bottom of the support frame 500 is fixedly connected to a second drive motor 501, the output shaft of the second drive motor 501 passes through the outer wall of the support frame 500 and is fixedly connected to the threaded rod 502, the external thread of the threaded rod 502 is connected to a movable connecting seat 503, and the outer wall of the connecting plate 101 is fixedly connected to one side of the movable connecting seat 503.

[0032] Specifically, in the lifting device, the second driving motor 501 can be started to drive the threaded rod 502 to rotate, and the threaded rod 502 can drive the movable connecting seat 503 to move up and down during the rotation. When the movable connecting seat 503 moves up and down, it can drive the connecting plate 101 to move up and down. Through the up and down movement of the connecting plate 101, the L-shaped connecting seat 105 and the graphite crucible can be driven to enter the interior of the water tank 100 for detection.

[0033] Furthermore, the staff can also inject water into the water tank 100, and after completing the quality uniformity test of the inner and outer walls of the graphite crucible, control the lifting device to sink the connecting plate 101 as a whole into the water tank 100, so that the graphite crucible enters the water, and the outside of the graphite crucible is wrapped by the water flow. When the graphite crucible is wrapped by the water flow, if cracks appear on the outer wall of the graphite crucible, the water flow will penetrate into the interior of the graphite crucible, so as to detect whether cracks appear on the inner and outer walls of the graphite crucible.

[0034] like Figure 4 As shown, the supporting rotating structure includes a first driving motor 115 , the output shaft of the first driving motor 115 passes through the outer wall of the connecting plate 101 and is fixedly connected to a rotating seat 116 , and the graphite crucible is placed on the rotating seat 116 .

[0035] Specifically, during use, after the graphite crucible is placed on the rotating seat 116, the rotating seat 116 can be driven to rotate by starting the first drive motor 115. When the rotating seat 116 is rotating, the graphite crucible on the rotating seat 116 can be driven to rotate. During the rotation of the graphite crucible, the multiple sleeve rods 107 on the inner and outer walls of the graphite crucible cooperate with the support spring 109 and the pressure sensor 110 to perform rapid detection of the average degree of convexity quality.

[0036] like Figure 1-Figure 3 As shown, the outer walls of the positioning connection seat 104 and the connection plate 101 are both provided with a plurality of threaded holes 600 , and the threaded holes 600 located outside the positioning connection seat 104 are threadedly connected with threaded plug rods 601 inside.

[0037] Specifically, during use, when the staff needs to adjust the position of the L-shaped connecting seat 105, the handle above the sliding plate 103 can be used to pull up or press down the sliding plate 103, so that the sliding plate 103 slides inside the sliding groove 102. The position of the sliding plate 103 is adjusted to drive the L-shaped connecting seat 105 located outside the sliding plate 103 to move up and down. When the L-shaped connecting seat 105 moves to the specified position, the threaded plug rod 601 passes through the outer wall of the positioning connecting seat 104 and is threadedly connected to the inside of the threaded hole 600, thereby fixing and limiting the positioning connecting seat 104 and the L-shaped connecting seat 105, thereby ensuring the stability of the L-shaped connecting seat 105 during operation.

[0038] Furthermore, the inner wall of the sliding groove 102 and the outer wall of the sliding plate 103 are both rough surfaces. By setting the rough surfaces of the sliding groove 102 and the sliding plate 103, the sliding plate 103 can be prevented from sliding freely inside the sliding groove 102, so that when the sliding plate 103 is adjusted, a certain support is guaranteed by the rough surfaces.

[0039] like Fig. 9 As shown, a placement cavity is provided at the bottom of the L-shaped connection seat 105 , and a bottom contact roller 700 is installed inside the placement cavity via a connection spring 701 .

[0040] Specifically, by setting the bottom contact roller 700 and the connecting spring 701, the L-shaped connecting seat 105 will not move up as a whole when the bottom of the graphite crucible is uneven. At the same time, a detector can be installed on the side of the connecting spring 701 close to the top wall of the cavity where the L-shaped connecting seat 105 is placed to detect whether the bottom of the graphite crucible is flat.

[0041] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, during the quality inspection process, the inner and outer walls of the graphite crucible are inspected for fitting and moving by means of a plurality of support rods 106 and sleeve rods 107, and during the inspection process, the graphite crucible is driven to rotate by means of the first drive motor 115 and the rotating seat 116, and during the rotation process, the plurality of sleeve rods 107 cooperate with the rolling wheels 108 and the support springs 109 to quickly inspect the uneven positions of the inner and outer walls of the graphite crucible, and the inner and outer walls of the graphite crucible are inspected in a cyclic manner with overall coverage, thereby accelerating the inspection speed as a whole and avoiding the occurrence of misaligned inspections.

[0042] Embodiment 2: Considering that during the detection process, although multiple sleeve rods 107, rolling wheels 108 and support springs 109 can quickly detect the inner and outer walls of the graphite crucible, the detection process mainly uses the data transmitted by the pressure sensor 110 to determine whether there is a phenomenon of uneven quality. In the case where the quality is uneven in time, the staff still needs to observe the location of the uneven quality by human eyes after the detection, and it is impossible to mark it during the detection process. In view of the above technical problems, the present application solves the above technical problems through the following technical solutions, specifically:

[0043] like Figure 5 As shown, the inner wall of the sleeve rod 107 is integrally formed with a load-bearing airbag 113, and the load-bearing airbag 113 is annularly wrapped around the support spring 109, and the outside of the load-bearing airbag 113 is integrally formed with a delivery pipe 114, and the outlet end of the delivery pipe 114 passes through the outer wall of the top pressure plate 111, and the outside of the load-bearing airbag 113 is connected to a material delivery shunt pipe 200, and the end of the material delivery shunt pipe 200 away from the top pressure plate 111 is connected to a material delivery pump 201, and the feed port of the material delivery pump 201 is connected to a feed hose, and the end of the feed hose away from the material delivery pump 201 is connected to a marking pigment storage box 202.

[0044] Specifically, during use, when the rolling wheel 108 continues to roll and continuously contacts the inner wall of the graphite crucible, once the rolling wheel 108 contacts the inner and outer walls of the graphite crucible with unevenness, the rolling wheel 108 will drive the top pressure plate 111 to slide inside the sleeve rod 107. At the same time, the top pressure plate 111 will only slide inside the limiting groove 112 when it only moves slightly. When the top pressure plate 111 slides inside the limiting groove 112, the top pressure plate 111 will squeeze the bearing airbag 113 located on one side of the top pressure plate 111. When the carrying airbag 113 is squeezed, the marking pigment injected into the carrying airbag 113 through the material delivery diversion pipe 200 will continue to be transported to the delivery pipe 114 due to the squeezing, and the marking pigment will be sprayed out through the delivery pipe 114. When the marking pigment is sprayed out through the delivery pipe 114, the uneven quality positions of the inner and outer walls of the graphite crucible can be marked, so that the staff can quickly find the uneven position when they detect that the quality of the graphite crucible is uneven and uneven, which is convenient for subsequent adjustments.

[0045] Furthermore, under normal conditions, the marking pigment in the marking pigment storage box 202 is continuously extracted by turning on the feed pump 201, and is simultaneously injected into the interior of multiple carrying airbags 113 through the feed diversion pipe 200, ensuring that the marking pigment inside the carrying airbag 113 is always filled.

[0046] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, when the inner and outer walls of the graphite crucible are inspected under the cooperation of multiple sleeve rods 107, rolling wheels 108 and support springs 109, once the multiple sleeve rods 107, rolling wheels 108 and support springs 109 detect that there are unevenness on the inner and outer walls of the graphite crucible, the rolling wheels 108 will drive the top pressure plate 111 to move toward the side close to the carrying airbag 113. When the top pressure plate 111 continues to move toward the position of the carrying airbag 113 and causes an extrusion state on the carrying airbag 113, the marking liquid inside the carrying airbag 113 will be sprayed out through the delivery pipe 114, thereby marking the position of uneven concave and convex quality, assisting the staff to quickly locate the position of uneven concave and convex quality, facilitating subsequent adjustments.

[0047] Embodiment 3: Considering that during use, although the marking pigment can be sprayed out through the delivery tube 114 to mark the uneven position of the graphite crucible during the detection process, during the continuous rotation process, when the delivery tube 114 sprays the pigment from one side of the rolling wheel 108, the marking pigment may be sprayed onto the outer wall surface of the rolling wheel 108 due to the rotation of the rolling wheel 108, and the continuous rotation of the rolling wheel 108 may cause secondary smearing of the pigment, resulting in the phenomenon that the outer surface of the rolling wheel 108 is attached with pigment at different positions, in view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0048] like Figure 6 As shown, the outside of the delivery pipe 114 is integrally formed with an arc-shaped hollow spray plate 300, the outside of the arc-shaped hollow spray plate 300 is provided with a plurality of spray holes 301, the inside of the spray hole 301 is integrally formed with a one-way valve plate 302, the arc-shaped hollow spray plate 300 is arc-shaped and is located on one side of the rolling wheel 108, and the opening of the spray hole 301 faces the connection between the rolling wheel 108 and the side wall of the graphite crucible.

[0049] Specifically, during use, the arc-shaped hollow spray plate 300 is set to penetrate the top pressure plate 111 and connect to the supporting airbag 113. The arc-shaped hollow spray plate 300 is set in an arc-shaped plate on one side of the rolling wheel 108, so that when the supporting airbag 113 is squeezed and the marking paint is sprayed out, it can be sprayed vertically through the multiple spray holes 301, and during the continuous rotation process, the vertically sprayed marking paint can completely cover the concave and convex positions, thereby making the marking position more obvious.

[0050] Furthermore, the arc-shaped hollow spray plate 300 is arranged on one side of the rolling wheel 108, and the opening of the spray hole 301 faces the connection between the rolling wheel 108 and the side wall of the graphite crucible, so that when the overall arc-shaped hollow spray plate 300 sprays out the marking paint through the spray hole 301, it will not be sprayed onto the outer wall of the rolling wheel 108, but will be sprayed onto the connection between the rolling wheel 108 and the side wall of the graphite crucible. Once the rolling wheel 108 touches the concave and convex position, the rolling wheel 108 drives the top pressure plate 111 to squeeze the bearing airbag 113 to spray the paint onto the position where the rolling wheel 108 contacts the graphite crucible, and the direction of spraying the paint is the same as the direction in which the rolling wheel 108 rolls, thereby avoiding the marking paint from being sprayed onto the outer wall of the rolling wheel 108, and avoiding the marking paint from being smeared on other positions of its graphite crucible when the outer wall of the rolling wheel 108 is covered with paint, thereby avoiding the phenomenon of causing incorrect marking.

[0051] Furthermore, the one-way valve plate 302 is provided to prevent the marking liquid inside the arc-shaped hollow spray plate 300 from flowing out in the absence of external pressure.

[0052] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, through the setting of the spray hole 301 of the arc-shaped hollow spray plate 300, in the process of spraying the marking pigment, vertical range spraying is performed, and in the spraying process, the spraying position is sprayed between the contact position of the rolling wheel 108 and the graphite crucible, thereby avoiding spraying the sprayed pigment on the outer wall of the rolling wheel 108, avoiding the rolling wheel 108 from driving the pigment to other positions of the graphite crucible, and avoiding the phenomenon of incorrect marking.

[0053] Embodiment 4: Considering that during use, when smaller depressions or protrusions appear, the rolling wheel 108 contacts these smaller depressions and protrusions, driving the top pressure plate 111 to exert a smaller extrusion force on the bearing airbag 113. When the extrusion force is smaller, the pigment sprayed through the spray hole 301 is also smaller. Because the extrusion force is smaller, the spraying distance through the spray hole 301 is also shorter. Therefore, these small amounts of sprayed pigments may not be able to contact the side wall of the graphite crucible. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0054] like Figure 7-Figure 8As shown, the arc-shaped hollow spray plate 300 includes a front-end adsorption connection layer 400, a soft connection layer 401 and a rear-end hard transmission box 403, the rear-end hard transmission box 403 and the conveying pipe 114 are integrally formed, the soft connection layer 401 is fixedly connected to the outer wall of the rear-end hard transmission box 403, the front-end adsorption connection layer 400 is integrally formed on the side of the soft connection layer 401 away from the rear-end hard transmission box 403, the spray hole 301 is opened on the outer wall of the front-end adsorption connection layer 400, the front-end adsorption connection layer 400 close to the L-shaped connecting seat 105 is made of magnetic material, and the front-end adsorption connection layer 400 close to the connecting plate 101 is made of metal iron.

[0055] Specifically, during use, if the arc-shaped hollow spray plate 300 is set to the initial state so that it can fit the shape of the crucible side wall, then when encountering different depressions, the arc-shaped hollow spray plate 300 that initially fits the crucible side wall will also contact the concave and convex graphite crucible side wall, which results in the arc-shaped hollow spray plate 300 that contacts the graphite crucible side also providing a certain reverse extrusion force, which may give a certain driving force to the support spring 109. Once a certain driving force is given to the support spring 109, it may affect the data transmission of the pressure sensor 110. Therefore, the arc-shaped hollow spray plates 300 on both sides of the graphite crucible are divided into different materials, and the front end adsorption connection layer 400 close to the L-shaped connecting seat 105 is made of magnetic material and the front end adsorption connection layer 400 close to the connecting plate 101 is made of magnetic material. 00 is made of metal iron, so that the front end adsorption connection layers 400 on both sides will be attracted to each other due to magnetic attraction during the detection process of bonding to the graphite crucible, thereby causing the soft connection layer 401 to extend and deform. When the soft connection layer 401 extends and deforms, the multiple front end adsorption connection layers 400 located on both sides of the graphite crucible will gradually move toward the side wall of the graphite crucible due to the deformation of the soft connection layer 401. When the deformed soft connection layer 401 contacts the side wall of the graphite crucible as a whole, even if the rolling wheel 108 only generates a small extrusion force and causes only a small amount of marking liquid to be sprayed out through the spray hole 301 inside the carrying airbag 113, these marking liquids will be accurately applied to the side wall of the graphite crucible, and there will be no situation where the marking liquid cannot be sprayed to the side wall of the graphite crucible.

[0056] Furthermore, when the front adsorption connection layer 400 contacts the side wall of the graphite crucible, even if the side wall of the graphite crucible bulges, the front adsorption connection layer 400 will only push the soft connection layer 401 to return to its original position, and will not cause the top pressure plate 111 to push the support spring 109 for the second time.

[0057] Furthermore, the front adsorption connection layer 400 and the rear hard transmission box 403 are both connected to a plurality of strip-shaped plug-in boards 402 on one side close to the soft connection layer 401 , and the plurality of strip-shaped plug-in boards 402 are plugged into the inside of the soft connection layer 401 and are connected in a staggered manner.

[0058] Specifically, when a plurality of strip-shaped plug-in plates 402 are connected by being staggered and plugged into each other, when the front-end adsorption connection layers 400 on both sides drive the soft connection layer 401 to deform under magnetic attraction, the front-end adsorption connection layer 400 located in the front will not be skewed at will, thereby ensuring that the front-end adsorption connection layer 400 can extend and move in the specified direction.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
