Description

Technical Field

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

[0002] A silicon carbide pump is a pump made of silicon carbide material, which has excellent wear resistance, corrosion resistance and high temperature resistance, and is widely used in fields such as chemical industry, mining, electric power, and environmental protection. The working principle of the silicon carbide pump is based on the basic principle of a centrifugal pump. The impeller is driven by a motor to rotate. The impeller sucks in and accelerates the liquid, and the liquid is thrown out under the action of centrifugal force, thereby realizing the transportation of the liquid.

[0003] After the silicon carbide pump has been used for a long time, in the spiral water passage area inside the silicon carbide pump housing, the impact and flow of water will cause local pressure changes, generating additional mechanical stress on the inside of the silicon carbide housing, resulting in the formation of pits or pit cracks inside the silicon carbide pump housing. Usually, the pits need to be repaired with a polymer composite silicon carbide ceramic material, and for the pit cracks, the pit crack area needs to be roughened first, and then the silicon carbide wear-resistant coating material is used to repair the pit cracks. Since the two repair methods are different, it is necessary to distinguish the types of pits inside the silicon carbide pump housing and then repair them according to their types.

[0004] Since the inside of the silicon carbide pump housing is a closed type, the existing detection method for the inside of the silicon carbide pump housing is to use an industrial endoscope to extend the camera into the inside of the silicon carbide pump housing to detect the pits inside. Since the shape of the inside of the silicon carbide pump housing is usually spiral, and the industrial endoscope cannot extend the camera to the deepest part of the inside of the silicon carbide pump housing, the detection area inside the silicon carbide pump housing is incomplete, resulting in the pits at the deepest part inside the silicon carbide pump housing not being detected, thereby reducing the accuracy of detecting the pits inside the silicon carbide pump housing and being unable to effectively detect the accurate positions of each pit inside the silicon carbide pump housing.

[0005] Therefore, it is very necessary to design a silicon carbide pump detection device that can extend deep into the spiral casing for shooting and has high accuracy in detecting pits. Summary of the Invention

According to the bending degree inside the volute, after the first connecting rod, the second connecting rod, and the third connecting rod touch the inner wall of the volute, they rotate in the same direction in sequence to adapt to the bending degree of the inner wall of the volute, so that the camera can take pictures from the inlet of the volute to the deepest part of the volute, achieving the effect that the camera adapts to extend deep into the volute for shooting.

[0018] 2. Before the camera takes pictures, first use the rotating scraper to scrape off the protruding limestone on the inner wall of the volute channel. During the scraping process, the spraying module sprays acidic liquid onto the inner wall of the volute channel, so that the acidic liquid is sprayed onto the limestone inside the pits. When the camera reaches the deepest part, the limestone on the inner wall of the volute channel reacts with the acidic liquid and generates bubbles. At this time, the camera is driven to retreat and starts to rotate and take pictures in segments. According to the bubbles of different shapes, the type of each pit is accurately identified. By taking pictures of the bubble shapes to identify the types of holes, it effectively prevents the phenomenon that when the limestone covers the surface of the pits, the camera cannot accurately identify the types of pits, and subsequent corresponding repair methods cannot be carried out according to their types, achieving the effect of high accuracy in identifying the types of pits.

[0019] 3. After the cleaning of limestone particles and the camera shooting are completed, the fan is started to suck the remaining limestone particles inside the volute channel into the inside of the storage chamber, effectively preventing the phenomenon that when the pits are repaired, the remaining limestone particles will cause wear to components such as the inner wall of the volute and the impeller when flowing inside the volute.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1, please refer to Figures 1-13 , the present invention provides a technical solution: a silicon carbide pump and its detection device, including a workbench 1, a side plate 2 is fixedly connected to one side of the workbench 1, a support plate 3 is fixedly connected to one side of the side plate 2, a controller 4 is fixedly connected to the upper side of the support plate 3, a transmission mechanism 5 is arranged on the upper side of the workbench 1, and a pressing mechanism 6 for collecting waste materials for cleaning the inside of the spiral channel is arranged on one side of the transmission mechanism 5.

[0023] Please refer toFigure 2 , the transmission mechanism 5 includes a first support block 51 fixedly connected to the upper side of the workbench 1. 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 sliding 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 spiral channel is provided inside the limiting groove 55. A connecting plate 54 is slidably connected inside the first sliding groove 56. One end of the connecting plate 54 is fixedly connected to the output end of the first cylinder 52. A liquid storage bucket 57 is provided on one side of the second support block 53. The inside of the liquid storage bucket 57 is used to store acidic liquid. A water pump 58 is fixedly connected to the outside of the liquid storage bucket 57, and the input end of the water pump 58 is connected to the output end of the liquid storage bucket 57 through a pipeline. The output end of the water pump 58 is fixedly connected to a hose 59.

[0024] Specifically, the telescoping 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 limiting groove 55, so as to push the cleaning mechanism 7 into the inside of the volute 63. The water pump 58 is used to extract the acidic liquid inside the liquid storage bucket 57, transport it to the hose 59, and then transport it to the inside of the cleaning mechanism 7 through the hose 59.

[0025] Please refer to Figure 3 , the cleaning mechanism 7 includes a third connecting rod 73 slidably connected inside the limiting groove 55. One end of the third connecting rod 73 is fixedly connected to the other end of the connecting plate 54. Three second connecting rods 72 are provided at the other end of the third connecting rod 73. 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 a first connecting rod 71. A dirt removing component 74 is provided at the other end of the first connecting rod 71.

[0026] Specifically, when the output end of the first cylinder 52 retracts, it drives the third connecting rod 73, the second connecting rod 72, the first connecting rod 71 and the dirt removing component 74 to move along the limiting groove 55 in sequence. The dirt removing component 74, the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 enter the inside of the volute 63 in sequence. According to the bending degree inside the volute 63, after the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 touch the inner wall of the volute 63, they rotate in the same direction in sequence, so that the dirt removing component 74 extends to the deepest part of the volute 63, so that the camera 7453 can photograph the deepest part of the volute 63 from the inlet of the volute 63.

[0027] Please refer to Figure 4, the dirt removal component 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 with a first motor 742. The output end of the first motor 742 is fixedly connected with a clamping column 747. The outside of the clamping column 747 is fixedly connected with a positioning block. The two sides of the first motor 742 are respectively provided with telescopic rods 746. One end of the telescopic rod 746 is fixedly connected with the rotating block 741 and the other end is provided with a spraying module 743. The inside of the spraying module 743 is provided with a photographing module 745. One side of the spraying module 743 is provided with a scraping module 744.

[0028] 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. The photographing module 745 is used to photograph the pit inside the volute 63.

[0029] Through the telescopic movement 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 component 74 are extended into or pulled out of the volute 63. According to the bending degree inside the volute 63, after the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73 touch the inner wall of the volute 63, they rotate in the same direction in turn to adapt to the bending degree of the inner wall of the volute 63, so that the camera 7453 can photograph the deepest part of the volute 63 from the inlet of the volute 63, achieving the effect that the camera 7453 adapts to extend into the deep part of the volute 63 for photographing.

[0030] Embodiment 2. Since the silicon carbide shell is usually used in harsh working conditions, such as treating slurries or gases containing solid particles, long-term operation will cause physical wear inside the silicon carbide shell, forming pits and pit seams. When the camera 7453 extends into the silicon carbide shell, since some limestone will fill into the pits, after the pits are filled with limestone, its surface becomes flat with the surrounding area. It is difficult for the camera 7453 to distinguish the existence of the pits through the shape difference and the white or light gray appearance of the limestone is similar to the color of the surrounding silicon carbide surface, further reducing the contrast of visual recognition, resulting in the inability to accurately identify the pits. Moreover, when the limestone covers the surface of the pits, the camera 7453 cannot accurately identify the types of the pits, resulting in the inability to perform corresponding repair methods according to their types in the follow-up. Therefore, the following structure is designed to solve the above technical problems.

[0031] Please refer to Figure 5, the spraying module 743 includes a guiding and sliding disc 7431 fixedly connected to the other end of the telescopic rod 746. A liquid storage tank 7434 is provided inside the guiding and sliding disc 7431. The other end of the hose 59 is fixedly connected to the liquid storage tank 7434. A number of spray nozzles 7432 are evenly and fixedly connected to the outside of the liquid storage tank 7434. A second sliding groove 7433 is provided on one side of the liquid storage tank 7434. A circular groove 7435 is provided on one side of the second sliding groove 7433. A circular T-groove is provided on the outside of the circular groove 7435. The clamping post 747 penetrates through the guiding and sliding disc 7431, and the positioning block is arranged inside the circular groove 7435.

[0032] Specifically, the acidic liquid inside the hose 59 is transported into the liquid storage tank 7434 and then ejected from the output ports of each spray nozzle 7432 in sequence, so as to be evenly sprayed inside the channel of the volute 63. The acidic liquid will react with the limestone, generating a large number of bubbles.

[0033] Please refer to Figure 6 , the photographing module 745 includes a rotating table 7451 arranged outside the clamping post 747. The rotating table 7451 is slidably connected to the second sliding groove 7433. A second clamping groove 7452 is provided inside the rotating table 7451. A camera 7453 is fixedly connected to one side of the rotating table 7451. An LED lamp 7454 is provided on one side of the camera 7453 and the LED lamp 7454 is fixedly connected to the rotating table 7451.

[0034] Specifically, the LED lamp 7454 is used to fill light for the image taken by the camera 7453 when the camera 7453 takes a photograph. The camera 7453 is used to photograph the inner wall of the channel of the volute 63 and convert the taken photo into an electrical signal and transmit it to the controller 4. A database is provided inside the controller 4. Identification photos of bubbles of different shapes are provided inside the database. When the controller 4 receives the photo sent by the camera 7453, it will compare it with the identification photos of bubbles of different shapes in the internal database, pre-identify the shape of the bubbles generated by the reaction of the acidic liquid and the limestone, and classify the types of pits into two types: holes and pit cracks according to the taken photo of the inner wall of the channel of the volute 63 obtained.

[0035] Please refer to Figure 7 and Figure 8, the scraping module 744 includes a circular T-shaped block 7447 slidably connected inside the circular T-slot. One side of the circular T-shaped block 7447 is fixedly connected to a turntable 7441. A first card slot 7448 is provided on one side of the turntable 7441 and four relief slots 7446 are provided on the other side. A rotating shaft 7445 is rotatably connected inside each relief slot 7446. A scraper 7442 is fixedly connected to the outer side of the rotating shaft 7445. A torsion spring 7444 is provided on the outer side 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.

[0036] Specifically, the scraper 7442 is made of a material with a hardness lower than that of silicon carbide, and can be made of carbon fiber material, which will not damage the inside 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 at the same time scrapes the limestone protruding from the inner wall of the volute 63 channel. 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 open 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. Since the diameter of the channel 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. Please refer to Figure 11 , at this time, several scrapers 7442 are in a fully contracted state.

[0037] When the output end of the first cylinder 52 starts to retract, the dirt removal component 74 starts to enter the inside of the volute 63 channel. At this time, the scraper 7442 presses against the inner wall of the volute 63. The output end of the first motor 742 rotates to drive the clamping post 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 impacts. The scraper 7442 is squeezed and starts to contract, generating a frictional force with the inner wall of the volute 63 channel. Since the frictional force between the scraper 7442 and the inner wall of the volute 63 channel is greater than the frictional force between the telescopic rods 746, the telescopic rods 746 start to contract. The clamping post 747 indirectly drives the positioning block to move forward. The positioning block moves forward and rotates, thus being stuck into the inside of the first card slot 7448, and then drives the four scrapers 7442 to rotate along the axis of the turntable 7441. 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 continuously move 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 pumps out the acidic liquid inside the liquid storage bucket 57, transports it to the hose 59, and then transports it to the inside of the liquid storage tank 7434 through the hose 59, and then shoots out from the output ports of each spray head 7432 in turn, so as to be evenly sprayed inside the channel of the volute 63. The acidic liquid will react with the limestone to generate bubbles. Scraping off the protruding limestone first and then spraying the acidic liquid can prevent the acidic liquid from forming bubbles on the surface of the protruding limestone, affecting the accuracy of the subsequent camera 7453 to identify the type of pit.

[0038] When reaching the deepest part, the output end of the first motor 742 stops rotating, the output end of the first cylinder 52 stops extending and starts to extend. Since the frictional force between the scraper 7442 and the inner wall of the volute 63 channel is greater than the frictional force between the telescopic rods 746, the telescopic rods 746 start to extend. The clamping post 747 indirectly drives the positioning block to move backward. When the positioning block enters the inside of the circular groove 7435, the output end of the first motor 742 starts to rotate. The positioning block moves backward and continues to rotate, thus being stuck into the inside of the second card slot 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 90 degrees of clockwise rotation. Each time it stops, the camera 7453 takes a photo. When rotating 270 degrees clockwise, the output end of the first motor 742 starts to rotate counterclockwise, stopping for one second every 90 degrees of counterclockwise rotation. Each time it stops, the camera 7453 takes a photo. When rotating 270 degrees counterclockwise, the output end of the first motor 742 stops rotating, and the output end of the first cylinder 52 extends a shooting distance and then stops extending again, so as to cycle through taking photos 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 out of the inside of the volute 63 channel, and the output end of the first cylinder 52 stops extending. At this time, all the photos of the inner wall of the volute 63 channel have been taken.

[0039] When the bubble shape captured by the camera 7453 is an elongated bubble, the controller 4 determines it as a pit crack, marks the position of the pit crack, and prompts that the pit crack area needs to be roughened first, and then the silicon carbide wear-resistant coating material is used to repair the pit crack.

[0040] When the bubble shape captured by the camera 7453 is a circular bubble, the controller 4 determines it as a pit hole, marks the position of the pit hole, and prompts that the polymer composite silicon carbide ceramic material needs to be used for repair.

[0041] The method of marking the position is to divide the volute 63 channel into x segments, and the length of each segment is the same as the distance that the output end of the first cylinder 52 extends. The number of segments of the concave pit in the volute 63 channel is obtained according to the number of times the output end of the first cylinder 52 extends.

[0042] Before the camera 7453 takes pictures, first use the rotating scraper 7442 to scrape off the protruding limestone on the inner wall of the volute 63 channel. During the scraping process, the spraying module 743 sprays acidic liquid onto the inner wall of the volute 63 channel, so that the acidic liquid is sprayed onto the limestone inside the concave pit. When the camera 7453 reaches the deepest part, the limestone on the inner wall of the volute 63 channel reacts with the acidic liquid to generate bubbles. At this time, the camera 7453 is driven to retreat and starts to rotate and take pictures in segments. According to the bubbles of different shapes, the type of each pit hole can be accurately identified. By identifying the type of hole through the shape of the captured bubble, it effectively prevents the phenomenon that when the limestone covers the surface of the pit hole, the camera 7453 cannot accurately identify the type of the concave pit, and the corresponding repair method cannot be carried out subsequently, achieving the effect of high accuracy in identifying the type of pit hole.

[0043] Embodiment 3. After the limestone is scraped or decomposed, the remaining limestone particles will remain inside the volute 63 and are difficult to be cleaned up. After the pit hole is repaired, when the remaining limestone particles flow inside the volute 63, they will cause wear to components such as the inner wall of the volute 63 and the impeller 87. Due to the high hardness of the limestone, its high-speed movement in the flow channel will cause scratches and concave pits on the inner wall of the volute 63 and the surface of the impeller 87, and may even make the wall thickness of the volute 63 thinner, affecting its structural strength. Therefore, the following structure is designed to solve the above technical problems.

[0044] Please refer to 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 penetrates through the support plate 3 and is fixedly connected with a pressing plate 62. A volute 63 is arranged below the pressing plate 62, a support column 64 is arranged below the volute 63, and a collecting component 65 is arranged on one side of the support column 64.

[0045] 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, so as to fix the volute 63.

[0046] Please refer to Figure 10 , a ventilation pipe 641 is provided inside the support column 64, the water inlet of the volute 63 is communicated with the ventilation pipe 641, the other end of the ventilation pipe 641 is fixedly connected with a collecting box 651, the feed inlet of the collecting box 651 is communicated with the ventilation pipe 641, a filter cartridge 653 is fixedly connected inside the collecting box 651, a stockpiling chamber 654 is provided on one side of the filter cartridge 653 and a fan 652 is fixedly connected on the other side.

[0047] Specifically, after the photographing of the pit inside the volute 63 is completed, the fan 652 is started to suck air. At this time, a negative pressure is generated inside the stockpiling chamber 654, sucking the limestone particles inside the volute 63 into the ventilation pipe 641, and then entering the inside of 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.

[0048] After the cleaning of the limestone particles is completed and the photographing by the camera 7453 is completed, the fan 652 is started to suck the remaining limestone particles inside the passage of the volute 63 into the inside of the stockpiling chamber 654, effectively preventing the phenomenon that after the pit repair is completed, the remaining limestone particles will cause wear to components such as the inner wall of the volute 63 and the impeller 87 when flowing inside the volute 63.

[0049] Example Four, please refer to Figure 12 and Figure 13 , a silicon carbide pump, including a base 86, a support platform 82 is fixedly connected to the upper side of the base 86, a second motor 81 is fixedly connected to the upper side of the support platform 82, a speed reducer 83 is provided on one side of the support platform 82 and the speed reducer 83 is fixedly connected to the base 86, the input end of the speed reducer 83 is fixedly connected to the output end of the second motor 81, the output end of the speed 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 penetrates through the pump casing 84 and is fixedly connected to an impeller 87, and a volute 88 is provided inside the pump casing 84.

[0050] Specifically, the rotation of the output end of the second motor 81 is used to control the rotation of the gears inside the speed reducer 83, thereby driving the connecting shaft 85 to rotate, and further driving the impeller 87 to rotate to convey the water source inside the volute 88.

[0051] The impeller 87 and the pump casing 84 are integrally cast and formed from silicon carbide and a multi-component polymer with chemical and thermal stability under vacuum, with an acid resistance reaching 99.7% and a silicon carbide content exceeding 80%.

[0052] The silicon carbide pump adopts a rear-disassembly structure. The impeller 87 and the connecting shaft 85 are connected by threads, with a simple structure, few components and convenient maintenance.
