Description

Technical Field

[0001] The present invention relates to the technical field of silicon carbide pump detection, and in particular to a silicon carbide pump and a detection device thereof. Background Art

[0002] Silicon carbide pumps are manufactured from silicon carbide and offer excellent resistance to wear, corrosion, and high temperatures. They are widely used in the chemical, mining, power, and environmental protection industries. They operate on the same principle as centrifugal pumps. A motor drives the impeller, which draws in and accelerates the liquid, causing it to be ejected under centrifugal force, thereby transporting the liquid.

[0003] After a silicon carbide pump has been used for too long, the impact and flow of water in the volute water-passing area inside the silicon carbide pump casing will cause local pressure changes, generating additional mechanical stress inside the silicon carbide shell, resulting in pits or cracks inside the silicon carbide pump casing. Usually, the pits need to be repaired with polymer composite silicon carbide ceramic materials, while the pit cracks need to be roughened first and then repaired with silicon carbide wear-resistant coating materials. The two repair methods are different, so it is necessary to distinguish the type of pits inside the silicon carbide pump casing and then repair them according to their type.

[0004] Since the interior of the silicon carbide pump casing is closed, the existing method for inspecting the interior of the silicon carbide pump casing is to use an industrial endoscope to insert the camera into the interior of the silicon carbide pump casing to inspect the pits inside. Since the shape of the interior of the silicon carbide pump casing is usually volute, the industrial endoscope cannot insert the camera to the deepest part of the silicon carbide pump casing, resulting in an incomplete inspection area inside the silicon carbide pump casing, making it impossible to detect the deepest pits inside the silicon carbide pump casing, thereby reducing the accuracy of detecting the pits inside the silicon carbide pump casing, and failing to effectively detect the exact position of each pit inside the silicon carbide pump casing.

[0005] Therefore, it is necessary to design a silicon carbide pump detection device that can reach deep into the volute to photograph and detect potholes with high accuracy. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the extension and retraction of the output end of the first cylinder, the third connecting rod, the second connecting rod, the first connecting rod and the dirt removal assembly are extended into or pulled out of the volute, and according to the curvature of the interior of the volute, the first connecting rod, the second connecting rod and the third connecting rod touch the inner wall of the volute and rotate in the same direction in turn to adapt to the curvature of the inner wall of the volute, so that the camera can shoot from the entrance of the volute to the deepest part of the volute, achieving the effect of the camera adaptively extending into the deep part of the volute to shoot.

[0019] 2. Before the camera shoots, the protruding limestone on the inner wall of the volute channel is scraped off by rotating the scraper. During the scraping process, the spray module sprays acidic liquid onto the inner wall of the volute channel, thereby spraying the acidic liquid on the limestone inside the pit. When the camera reaches the deepest point, the limestone on the inner wall of the volute channel reacts with the acidic liquid and produces bubbles. At this time, the camera is driven backward and starts to rotate and shoot in sections. According to the different shapes of bubbles, the type of each pit is accurately identified. By shooting the bubble shape to identify the type of hole, it effectively prevents the camera from being unable to accurately identify the type of pit when limestone covers the surface of the pit, and subsequently unable to perform the corresponding repair method according to its type, thereby achieving a high accuracy in pit type identification.

[0020] 3. After the limestone particles are cleaned and the camera shooting is completed, the fan starts to suck the limestone particles remaining inside the volute channel into the inside of the stockpile chamber, which effectively prevents the residual limestone particles from flowing inside the volute after the pothole repair is completed, causing wear on the inner wall of the volute, impeller and other components.

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 making creative efforts are within the scope of protection of the present invention.

[0041] For example 1, please refer to Figure 1-13 The present invention provides a technical solution: a silicon carbide pump and a detection device thereof, comprising a workbench 1, a side plate 2 being fixedly connected to one side of the workbench 1, a support plate 3 being fixedly connected to one side of the side plate 2, a controller 4 being fixedly connected to the upper side of the support plate 3, a transmission mechanism 5 being provided on the upper side of the workbench 1, and a pressing mechanism 6 for collecting waste cleaned from the inside of the volute channel being provided on one side of the transmission mechanism 5.

[0042] See also Figure 2 The transmission mechanism 5 includes a first support block 51 fixedly connected to the upper side of the workbench 1, and a first cylinder 52 is fixedly connected to the upper side of the first support block 51. A second support block 53 is provided on one side of the first support block 51, and a limiting groove 55 and a first slide groove 56 are respectively provided on the upper side of the second support block 53. A cleaning mechanism 7 for cleaning and photographing the inside of the volute channel is provided inside the limiting groove 55. A connecting plate 54 is slidably connected to the inside of the first slide groove 56, and one end of the connecting plate 54 is fixedly connected to the output end of the first cylinder 52. A liquid storage barrel 57 is provided on one side of the second support block 53. The interior of the liquid storage barrel 57 is used to store acidic liquid. A water pump 58 is fixedly connected to the outside of the liquid storage barrel 57, and the input end of the water pump 58 is connected to the output end of the liquid storage barrel 57 through a pipe. The output end of the water pump 58 is fixedly connected to a hose 59.

[0043] Specifically, the extension and retraction of the output end of the first cylinder 52 is used to control the movement of the connecting plate 54, indirectly driving the cleaning mechanism 7 to slide along the limit groove 55, thereby pushing the cleaning mechanism 7 into the interior of the volute 63, and the water pump 58 is used to extract the acidic liquid inside the liquid storage barrel 57 and transport it to the hose 59, and then transport it to the interior of the cleaning mechanism 7 through the hose 59.

[0044] See also Figure 3 The cleaning mechanism 7 includes a third connecting rod 73 that is slidably connected to the inside of the limiting groove 55. One end of the third connecting rod 73 is fixedly connected to the other end of the connecting plate 54. The other end of the third connecting rod 73 is provided with three second connecting rods 72. The three second connecting rods 72 are hinged to each other. One end of the three second connecting rods 72 is hinged to the third connecting rod 73 and the other end is hinged to the first connecting rod 71. The other end of the first connecting rod 71 is provided with a dirt removal component 74.

[0045] Specifically, the output end of the first cylinder 52 retracts, driving the third connecting rod 73, the second connecting rod 72, the first connecting rod 71 and the dirt removal assembly 74 to move along the limiting groove 55 in turn, and the dirt removal assembly 74, the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 enter the interior of the volute 63 in sequence. According to the degree of curvature inside the volute 63, the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 touch the inner wall of the volute 63 and then rotate in the same direction, so that the dirt removal assembly 74 extends into the deepest part of the volute 63, so that the camera 7453 can shoot the deepest part of the volute 63 from the entrance of the volute 63.

[0046] See also Figure 4 The dirt removal assembly 74 includes a rotating block 741 hinged to the other end of the first connecting rod 71, one side of the rotating block 741 is fixedly connected to the first motor 742, the output end of the first motor 742 is fixedly connected to a clamping column 747, the outer side of the clamping column 747 is fixedly connected to a positioning block, and telescopic rods 746 are respectively provided on both sides of the first motor 742, one end of the telescopic rod 746 is fixedly connected to the rotating block 741 and the other end is provided with a spray module 743, a shooting module 745 is provided inside the spray module 743, and a scraping module 744 is provided on one side of the spray module 743.

[0047] Specifically, the rotation of the output end of the first motor 742 is used to control the rotation of the clamping column 747, the scraping module 744 is used to scrape off the protruding limestone, the spraying module 743 is used to spray the acidic liquid on the surface of the limestone inside the pit, so that the limestone reacts with the acidic liquid to produce obvious bubbles, and the shooting module 745 is used to shoot the pit inside the volute 63.

[0048] Through the extension and retraction of the output end of the first cylinder 52, the third connecting rod 73, the second connecting rod 72, the first connecting rod 71 and the dirt removal assembly 74 are extended into or pulled out of the interior of the volute 63, and according to the degree of curvature inside the volute 63, the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 touch the inner wall of the volute 63 and rotate in the same direction in turn to adapt to the curvature of the inner wall of the volute 63, so that the camera 7453 can shoot from the entrance of the volute 63 to the deepest part of the volute 63, achieving the effect of the camera 7453 adaptively extending into the deep part of the volute 63 to shoot.

[0049] In the second embodiment, since silicon carbide shells are usually used in harsh working conditions, such as processing slurries or gases containing solid particles, long-term operation will cause physical wear on the inside of the silicon carbide shell, forming pits and cracks. When the camera 7453 is extended into the interior of the silicon carbide shell, part of the limestone will fill the inside of the pit. After the limestone fills the pit, its surface and the surrounding area become flat. It is difficult for the camera 7453 to distinguish the existence of the pit by the shape difference, and the white or light gray appearance of the limestone is similar to the color of the surrounding silicon carbide surface, which further reduces the contrast of visual recognition, resulting in the inability to accurately identify the pit. When the limestone covers the surface of the pit, the camera 7453 cannot accurately identify the type of pit, resulting in the inability to perform the corresponding repair method according to its type. Therefore, the following structure is designed to solve the above technical problems.

[0050] See also Figure 5 The spray module 743 includes a guide slide plate 7431 fixedly connected to the other end of the telescopic rod 746, a liquid storage tank 7434 is provided inside the guide slide plate 7431, the other end of the hose 59 is fixedly connected to the liquid storage tank 7434, and a number of nozzles 7432 are evenly and fixedly connected to the outside of the liquid storage tank 7434. A second slide groove 7433 is provided on one side of the liquid storage tank 7434, and a circular groove 7435 is provided on one side of the second slide groove 7433. A circular T-groove is provided on the outside of the circular groove 7435. The clamping column 747 passes through the guide slide plate 7431, and the positioning block is provided inside the circular groove 7435.

[0051] Specifically, the acidic liquid in the hose 59 is transported to the interior of the liquid storage tank 7434 and then ejected from the output port of each nozzle 7432 in sequence, thereby evenly spraying the interior of the channel of the volute 63. The acidic liquid reacts with the limestone to generate a large number of bubbles.

[0052] See also Figure 6 The shooting module 745 includes a rotating platform 7451 arranged on the outside of the clamping column 747, the rotating platform 7451 is slidably connected to the second slide groove 7433, and a second clamping groove 7452 is provided inside the rotating platform 7451. A camera 7453 is fixedly connected to one side of the rotating platform 7451, and an LED lamp 7454 is provided on one side of the camera 7453, and the LED lamp 7454 is fixedly connected to the rotating platform 7451.

[0053] Specifically, the LED light 7454 is used to fill in the light of the image taken by the camera 7453 when the camera 7453 is taking pictures. The camera 7453 is used to take pictures of the inner wall of the channel of the volute 63, and convert the taken pictures into electrical signals and transmit them to the controller 4. The controller 4 has a database inside, and the database has identification pictures of bubbles of different shapes. When the controller 4 receives the pictures sent by the camera 7453, it will compare them with the identification pictures of bubbles of different shapes in the internal database, and pre-identify the shape of the bubbles produced by the reaction of the acidic liquid and the limestone, and according to the pictures of the inner wall of the channel of the volute 63 obtained, the types of pits are divided into two types of pits: holes and cracks.

[0054] See also Figure 7 and Figure 8 The scraping module 744 includes a circular T-shaped block 7447 that is slidably connected to the inside of the circular T-groove. A turntable 7441 is fixedly connected to one side of the circular T-shaped block 7447. A first slot 7448 is provided on one side of the turntable 7441 and four avoidance slots 7446 are provided on the other side. Each avoidance slot 7446 is rotatably connected to a rotating shaft 7445. A scraper 7442 is fixedly connected to the outside of the rotating shaft 7445. A torsion spring 7444 is provided on the outside of the rotating shaft 7445. Positioning plates 7443 are fixedly connected to both sides of the scraper 7442. One end of the torsion spring 7444 is fixedly connected to the turntable 7441 and the other end is fixedly connected to the positioning plate 7443.

[0055] Specifically, the scraper 7442 is made of a material with a hardness lower than that of silicon carbide, such as carbon fiber, which will not damage the interior of the silicon carbide shell. The scraper 7442 is driven by the output end of the first cylinder 52 to move in the internal channel of the volute 63 and simultaneously scrapes away the limestone protruding from the inner wall of the channel of the volute 63. In the initial state, due to the elasticity of the torsion spring 7444, please refer to Figure 7 In the initial state, the scraper 7442 is in a fully opened state. When the scraper 7442 is brought into the internal channel of the volute 63, the scraper 7442 is squeezed by the inner wall of the volute 63 channel. As the channel diameter of the volute 63 is getting smaller and smaller, when the scraper 7442 reaches the deepest part of the volute 63 channel, several scrapers 7442 are squeezed and contracted together. Figure 11 At this time, several scrapers 7442 are in a fully retracted state.

[0056] When the output end of the first cylinder 52 begins to retract, the dirt removal assembly 74 begins to enter the interior of the volute 63 channel. At this time, the scraper 7442 presses against the inner wall of the volute 63, and the output end of the first motor 742 rotates to drive the clamping column 747 to rotate. Since in the initial state, the positioning block is inside the circular groove 7435, the rotation of the positioning block will not cause other effects. The scraper 7442 is squeezed and begins to shrink, and friction is generated with the inner wall of the volute 63 channel. Since the friction between the scraper 7442 and the inner wall of the volute 63 channel is greater than the friction between the telescopic rod 746, the telescopic rod 746 begins to shrink, and the clamping column 747 indirectly drives the positioning block to move forward. The positioning block moves forward and rotates, thereby getting stuck in the first clamping groove 7448, and then drives the four scrapers 7442 along the turntable 7441 The axis rotates, and the scraper 7442 hits the protruding limestone, thereby scraping off the protruding limestone on the inner wall of the volute 63 channel. The scraper 7442 is driven to continue moving deeper into the volute 63 channel, bringing the scraped limestone particles to the deepest part of the volute 63 channel. While moving, the water pump 58 extracts the acidic liquid from the liquid storage barrel 57 and transports it to the hose 59. Then, it is transported to the inside of the liquid storage tank 7434 through the hose 59, and then ejected from the output port of each nozzle 7432 in turn, so as to be evenly sprayed on the inside of the channel of the volute 63. The acidic liquid will react with the limestone to produce bubbles. The protruding limestone is scraped off first and then the acidic liquid is sprayed to prevent the acidic liquid from being sprayed on the surface of the protruding limestone to form bubbles, which affects the accuracy of the subsequent camera 7453 in identifying the pit type.

[0057] When it reaches the deepest point, the output end of the first motor 742 stops rotating, and the output end of the first cylinder 52 stops extending and starts to extend. Since the friction between the scraper 7442 and the inner wall of the volute 63 channel is greater than the friction between the telescopic rod 746, the telescopic rod 746 starts to extend, and the clamping column 747 indirectly drives the positioning block to move backward. When the positioning block enters the interior of the circular groove 7435, the output end of the first motor 742 starts to rotate, and the positioning block continues to move backward and rotate, thereby being stuck in the interior of the second clamping groove 7452. The output end of the first cylinder 52 stops extending, and the output end of the first motor 742 starts to rotate slowly, stopping for one second every time it rotates ninety degrees clockwise. Stop, camera 7453 takes a picture, when it rotates 270 degrees clockwise, the output end of the first motor 742 starts to rotate counterclockwise, and stops for one second every time it rotates 90 degrees counterclockwise. Every time it stops, the camera 7453 takes a picture, when it rotates 270 degrees counterclockwise, the output end of the first motor 742 stops rotating, the output end of the first cylinder 52 extends one end of the shooting distance and then stops extending again, so as to cyclically take pictures of the upper, lower, left and right areas of the inner wall of the volute 63 channel in turn, until the camera 7453 is taken away from the inside of the volute 63 channel, the output end of the first cylinder 52 stops extending, and at this time all pictures of the inner wall of the volute 63 channel are taken.

[0058] When the bubble shape captured by the camera 7453 is a long bubble, the controller 4 determines that it is a pit, marks the position of the pit, and prompts that the pit area needs to be roughened first, and then the pit is repaired with silicon carbide wear-resistant coating material.

[0059] When the bubble shape captured by the camera 7453 is a round bubble, the controller 4 determines that it is a pothole, marks the location of the pothole, and prompts that it needs to be repaired using a polymer composite silicon carbide ceramic material.

[0060] The method of marking the position is to divide the volute 63 channel into x sections, where the length of each section is the same as the distance the output end of the first cylinder 52 extends. The section of the volute 63 channel where the pit is located is determined based on the number of times the output end of the first cylinder 52 extends.

[0061] Before the camera 7453 takes pictures, the scraper 7442 is rotated to scrape off the limestone protruding from the inner wall of the volute 63 channel. During the scraping process, the spray module 743 sprays acidic liquid onto the inner wall of the volute 63 channel, thereby spraying the acidic liquid on the limestone inside the pit. When the camera 7453 reaches the deepest point, the limestone on the inner wall of the volute 63 channel reacts with the acidic liquid and produces bubbles. At this time, the camera 7453 is driven backward and starts to rotate and shoot in segments. According to the different shapes of bubbles, the type of each pit is accurately identified. By photographing the shape of the bubbles to identify the type of the hole, it effectively prevents the camera 7453 from being unable to accurately identify the type of the pit when limestone covers the surface of the pit, and subsequently failing to perform the corresponding repair method according to its type, thereby achieving a high accuracy in identifying the pit type.

[0062] In the third embodiment, after the limestone is scraped or decomposed, the residual limestone particles will remain inside the volute 63 and are difficult to clean. After the pothole repair is completed, the residual limestone particles will flow inside the volute 63 and will cause wear on the inner wall of the volute 63, the impeller 87 and other components. Due to the high hardness of the limestone, its high-speed movement in the flow channel will cause scratches and pits on the inner wall of the volute 63 and the surface of the impeller 87, and may even cause the wall thickness of the volute 63 to become thinner, affecting its structural strength. Therefore, the following structure is designed to solve the above technical problems.

[0063] See also Figure 9 The pressing mechanism 6 includes a second cylinder 61 fixedly connected to the upper side of the support plate 3. The output end of the second cylinder 61 passes through the support plate 3 and is fixedly connected to a pressing plate 62. A volute 63 is provided on the lower side of the pressing plate 62. A support column 64 is provided on the lower side of the volute 63. A collecting assembly 65 is provided on one side of the support column 64.

[0064] Specifically, the extension of the output end of the second cylinder 61 is used to press the pressing plate 62 on the upper side of the volute 63, thereby fixing the volute 63.

[0065] See also Figure 10 A ventilation pipe 641 is provided inside the support column 64, the water inlet of the volute 63 is connected to the ventilation pipe 641, the other end of the ventilation pipe 641 is fixedly connected to the collection box 651, the feed port of the collection box 651 is connected to the ventilation pipe 641, and a filter cartridge 653 is fixedly connected inside the collection box 651. A stacking chamber 654 is provided on one side of the filter cartridge 653 and a fan 652 is fixedly connected to the other side.

[0066] Specifically, after the photo of the pit inside the volute 63 is taken, the fan 652 starts and begins to suck air. At this time, negative pressure is generated inside the stockpiling chamber 654, and the limestone particles inside the volute 63 are sucked into the ventilation pipe 641, and then enter the stockpiling chamber 654 from the ventilation pipe 641. The filter cartridge 653 filters the limestone particles to prevent them from entering the fan 652, and the sucked limestone particles are stored inside the stockpiling chamber 654.

[0067] After the limestone particles are cleaned and the camera 7453 finishes shooting, the fan 652 starts to suck the limestone particles remaining in the channel of the volute 63 into the interior of the stockpile chamber 654, effectively preventing the residual limestone particles from flowing inside the volute 63 after the pothole repair is completed, causing wear on the inner wall of the volute 63, the impeller 87 and other components.

[0068] For example 4, please refer to Figure 12 and Figure 13 A silicon carbide pump includes a base 86, the upper side of the base 86 is fixedly connected to a support platform 82, the upper side of the support platform 82 is fixedly connected to a second motor 81, a reducer 83 is provided on one side of the support platform 82, and the reducer 83 is fixedly connected to the base 86, the input end of the reducer 83 is fixedly connected to the output end of the second motor 81, the output end of the reducer 83 is fixedly connected to a connecting shaft 85, a sealing ring is provided on the outside of the connecting shaft 85, a pump casing 84 is provided on the upper side of the base 86, the other end of the connecting shaft 85 passes through the pump casing 84 and is fixedly connected to an impeller 87, and a volute 88 is provided inside the pump casing 84.

[0069] Specifically, the rotation of the output end of the second motor 81 is used to control the rotation of the internal gear of the reducer 83, thereby driving the connecting shaft 85 to rotate, and then driving the impeller 87 to rotate, and transporting the water source inside the volute 88.

[0070] The impeller 87 and the pump housing 84 are integrally cast under vacuum from silicon carbide and a multi-component polymer having chemical resistance and thermal stability, with an acid resistance of 99.7% and a silicon carbide content exceeding 80%.

[0071] The silicon carbide pump adopts a rear disassembly structure, and the impeller 87 and the connecting shaft 85 are connected by threads, which has a simple structure, few parts and is easy to maintain.
