Description

Technical Field

[0001] This utility model relates to the field of reactor maintenance technology, and in particular to a high-pressure water cleaning device for explosion-proof and flammable reactors with visual monitoring function. Background Technology

[0002] In industries such as chemical, petroleum, and pharmaceutical, explosion-proof flammable reactors are key equipment for various chemical reactions. Due to the residue of materials, the adhesion of impurities, and the deposition of chemical reaction products during the reaction process, scale will form on the inner wall of the reactor. This scale will not only affect the heat transfer and mass transfer efficiency of the reactor and interfere with the normal progress of subsequent reactions, but may also cause safety hazards. Therefore, it is necessary to clean the reactor with high-pressure water regularly.

[0003] Currently, the traditional high-pressure water cleaning method for closed reactors mainly uses high-pressure water supply. The nozzle is inserted into the reactor through a pipeline and rinsed with a multi-angle rotating nozzle. Usually, a linear drive module moves the water pipe up and down. In addition, existing technologies also install a valve and a storage chamber at the top of the reactor. When not in use, the nozzle is placed in the storage chamber and the valve is closed. When cleaning is required, the valve is opened and the linear drive module moves the nozzle down from the storage chamber, through the valve, and into the reactor to perform the cleaning operation.

[0004] However, with the commonly used high-pressure water cleaning method, operators cannot directly and in real time observe the cleaning status inside the reactor, making it difficult to judge whether the cleaning is thorough. This can easily lead to insufficient cleaning resulting in dirt residue, or excessive cleaning causing water waste and increased equipment wear. Summary of the Invention

The outer surfaces of each active guide wheel and each limiting guide wheel are in contact with the outer surface of the first hose.

[0016] The second drive unit is used to drive the two active guide wheels to rotate synchronously in opposite directions, thereby causing the first hose to reciprocate along the first direction.

[0017] According to the technical solution provided in the embodiments of this application, the camera component includes:

[0018] The camera unit includes an explosion-proof enclosure, a camera disposed inside the explosion-proof enclosure, and a lighting lamp disposed at the bottom of the explosion-proof enclosure;

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. A camera system is installed, which, through the camera and lighting, can capture images of the cleaning process inside the reactor, allowing for real-time monitoring. Based on information such as the amount of dirt residue and the effectiveness of water rinsing, cleaning parameters can be adjusted promptly to optimize the cleaning process, avoid ineffective or excessive cleaning, shorten cleaning time, and improve cleaning efficiency. Furthermore, operators can complete the cleaning monitoring work without entering the reactor or disassembling it, reducing the risk of contact with hazardous substances and ensuring personal safety.

[0026] 3. A deflection drive mechanism is installed between the camera assembly and the first flexible hose. By injecting air into one airbag, the camera assembly is deflected to the other side, increasing the shooting range of the camera assembly and achieving all-round shooting to avoid blind spots in visual monitoring. The camera in the camera assembly is set downwards, and after deflection, it can capture the cleaning status of the inner wall of the reactor. Furthermore, the camera assembly is equipped with an air sweeping part. Air is injected into the air outlet through the second air injection pipe, and the blown airflow sweeps the surface of the camera to prevent dust or liquid from adhering to the camera surface, ensuring the clarity of visual monitoring.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0047] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Please refer to Figures 1-9 The present invention provides a high-pressure water cleaning device for explosion-proof flammable reactors with visual monitoring function, comprising:

[0049] The lifting and cleaning mechanism 1 includes a storage chamber 11 connected to the reaction vessel. A support plate 12 is provided at the top of the storage chamber 11. A telescopic liquid delivery pipe 14, movable along a first direction, is provided on the support plate 12. The storage chamber 11 and the telescopic liquid delivery pipe 14, when combined, have a first axis, the extension direction of which is the first direction. The bottom end of the telescopic liquid delivery pipe 14 extends along the first direction through the support plate 12 into the interior of the storage chamber 11 and is equipped with a rotating nozzle 15. The first direction is... Figure 1 The vertical direction in the middle, refer to Figure 1 A linear drive module 13 is set on the support plate 12. A pipe clamp is set on the slider of the linear drive module 13. The pipe clamp holds the telescopic liquid delivery pipe 14, so as to drive the telescopic liquid delivery pipe 14 to move up and down. A nozzle 16 is installed on one side of the rotary nozzle 15. High-pressure water flows through the telescopic liquid delivery pipe 14 and the rotary nozzle 15 and is sprayed out from the nozzle 16. Optionally, the rotary nozzle 15 and the nozzle 16 are selected from existing rotary all-angle nozzles, which can spray high-pressure water onto the inner wall of the reactor at different angles and pressures to achieve comprehensive cleaning.

[0050] The monitoring device 2 includes a first flexible tube 21 located on one side of the telescopic liquid delivery tube 14. The bottom end of the first flexible tube 21 extends through the support plate 12 along the first direction into the interior of the storage chamber 11 and is equipped with a camera component 4. The camera component 4 is used to photograph the inner wall of the reactor.

[0051] The monitoring mechanism 2 also includes a second lifting assembly 6 and a reversing assembly 5. The second lifting assembly 6 is used to drive the first hose 21 to move along the first direction, thereby driving the camera assembly 4 to move synchronously. The reversing assembly 5 is used to drive the first hose 21 and the camera assembly 4 to rotate around the first axis.

[0052] like Figures 1 to 5 As shown, the camera component 4 can capture images of the cleaning process inside the reactor, monitor the cleaning process in real time, and adjust cleaning parameters and optimize the cleaning process in a timely manner based on information such as the amount of dirt residue and the effect of water rinsing in the images. This avoids ineffective and excessive cleaning, shortens cleaning time, and improves cleaning efficiency. At the same time, operators can complete the cleaning monitoring work without entering the reactor or disassembling it, reducing the risk of contact with hazardous substances and ensuring personal safety.

[0053] Furthermore, since the telescopic liquid delivery pipe 14 and the rotating nozzle 15 are located at the center of the parking compartment 11, the position of the first hose 21 and the camera component 4 is adjusted by the reversing component 5. On the one hand, this avoids obstacles on the rotating nozzle 15, allowing the camera component 4 to move downwards stably. On the other hand, it facilitates the adjustment of the position of the camera component 4 relative to the rotating nozzle 15 or the telescopic liquid delivery pipe 14, preventing the rotating nozzle 15 or the telescopic liquid delivery pipe 14 from blocking the shooting position of the camera component 4. At the same time, the second lifting component 6 ensures the up and down movement of the first hose 21.

[0054] In some embodiments, the commutation component 5 includes:

[0055] The rotating part includes a turntable 51 coaxially arranged with the telescopic liquid delivery tube 14. The turntable 51 is mounted on the top of the support plate 12 via a plane bearing 57. The turntable 51 has a second through hole 510 located at the center of the turntable 51 for the telescopic liquid delivery tube 14 to pass through, and a first through hole 53 for the first hose 21 to pass through.

[0056] The first drive unit is used to drive the turntable 51 to rotate around the first axis, and drive the first hose 21 to rotate through the first through hole 53;

[0057] like Figure 3 , Figure 4 and Figure 5 As shown, the first drive unit includes a first mounting bracket 54 mounted on the support plate 12. A first motor 55 is mounted on the first mounting bracket 54. A first drive gear 56 is mounted on the output shaft of the first motor 55. A first driven gear 52 meshes with the first drive gear 56 on the turntable 51. Through meshing transmission, the first motor 55 drives the turntable 51 to rotate. The turntable 51 rotates about the first axis, which will not interfere with the telescopic liquid delivery tube 14, ensuring that the first through hole 53 drives the first hose 21 to rotate, thereby driving the camera assembly. 4. The rotating device rotates around the telescopic liquid delivery pipe 14 to prevent the telescopic liquid delivery pipe 14 or the rotating nozzle 15 from interfering with the shooting of the camera component 4. Optionally, the bottom end of the turntable 51 is provided with an outer sealing ring 58 that surrounds the plane bearing 57 and is coaxially arranged, and an inner sealing ring 59 that is provided in the plane bearing 57 and is coaxially arranged, to improve the sealing performance of the parking chamber 11 and reduce the entry of external gas into the parking chamber 11. Furthermore, the support plate 12 is provided with an annular mounting groove, so that the plane bearing 57 is embedded and installed in the annular mounting groove, thereby improving the stability of the rotation of the turntable 51.

[0058] In some embodiments, the second lifting component 6 includes:

[0059] Mounting plate 61 is located at the top of turntable 51;

[0060] The guide section, located on the mounting plate 61, includes two active guide wheels 63 at the same horizontal height and several limiting groups. Each limiting group includes two limiting guide wheels 69 at the same horizontal height. The axes of the limiting guide wheels 69 and the active guide wheels 63 are parallel to each other and perpendicular to the extension direction of the middle part of the first hose 21. The outer surfaces of each active guide wheel 63 and each limiting guide wheel 69 are in contact with the outer surface of the first hose 21.

[0061] The second drive unit is used to drive the two active guide wheels 63 to rotate synchronously in opposite directions, thereby driving the first hose 21 to reciprocate along the first direction.

[0062] like Figure 3 , Figure 4 and Figure 6 As shown, the second drive unit drives the active guide wheel 63 to rotate, causing the first hose 21 to move upward or downward. At least one set of limiting guide wheels 69 are provided to improve the stability of the first hose 21 during lifting and lowering. Furthermore, the second drive unit includes a second mounting bracket 65 mounted on the mounting plate 61. A second motor 66 is mounted on the second mounting bracket 65, and a second drive gear 67 is mounted on the output shaft of the second motor 66. Each active guide wheel 63 and each limiting guide wheel 69 is mounted to the mounting plate 61 via a mounting shaft 62, and is connected to the active guide wheel 63. Each of the corresponding mounting shafts 62 is equipped with a second driven gear 64. The mounting plate 61 is also provided with a reversing gear 68 that meshes with the second driving gear 67. The reversing gear 68 meshes with one of the second driven gears 64, and the second driving gear 67 meshes with the other second driven gear 64. The second driving gear 67 is driven by the second motor 66. Through the action of the reversing gear 68, the two second driven gears 64 and the two driving guide wheels 63 are driven to rotate synchronously in opposite directions, thereby realizing the purpose of driving the first hose 21 to reciprocate along the first direction.

[0063] In some embodiments, the camera component 4 includes:

[0064] The camera unit includes an explosion-proof housing 41, a camera 42 disposed inside the explosion-proof housing 41, and a lighting lamp 43 disposed at the bottom of the explosion-proof housing 41.

[0065] The air sweeping unit includes an air outlet 49 provided on the explosion-proof housing 41, with the opening of the air outlet 49 facing the shooting mirror of the camera 42. The first flexible hose 21 is provided with a second air injection pipe 410, with the bottom end of the second air injection pipe 410 connected to the air outlet 49 and the top end connected to the air source.

[0066] like Figure 2 and Figure 8As shown, the brightness inside the reactor is increased by the illumination lamp 43 to ensure clear images are captured. Optionally, the camera 42 is a wide-angle type to further expand the shooting range. In addition, air is injected into the air outlet 49 through the second air injection pipe 410, and the blown airflow sweeps the surface of the camera 42 to prevent dust or liquid from sticking to the surface of the camera 42, ensuring clear visual monitoring.

[0067] In some embodiments, the explosion-proof housing 41 is provided with a sliding chamber 45 at the bottom end, a telescopic column 47 is installed inside the sliding chamber 45, a first channel 48 is provided at the top of the telescopic column 47, an air outlet 49 communicating with the first channel 48 is provided on the side surface of the bottom of the telescopic column 47 near the camera 42, the top of the telescopic column 47 is connected to the top of the sliding chamber 45 through a return spring 46, and the top of the sliding chamber 45 is connected to the second air injection pipe 410 through a second channel 411.

[0068] like Figure 2 and Figure 8 As shown, when no gas is injected, the reset spring 46 drives the telescopic column 47 to retract into the sliding chamber 45. When it is necessary to clean the surface of the camera 42, gas is injected through the second gas injection pipe 410. The gas enters the sliding chamber 45 through the second channel 411, pushing the telescopic column 47 out of the sliding chamber 45. At this time, the gas is sprayed out from the air outlet 49 along the first channel 48. Thus, on the basis of purging and cleaning, the air outlet 49 is collected, avoiding the situation where the air outlet 49 is blocked, and ensuring a continuous and effective purging effect.

[0069] In some embodiments, the monitoring mechanism 2 further includes a lateral drive assembly 3. The lateral drive assembly 3 includes a second hose 31 connecting the bottom end of the first hose 21 and the top end of the explosion-proof housing 41. Two airbags 33 are symmetrically arranged inside the second hose 31. The first hose 21 is provided with two first air injection tubes 32. The bottom ends of the two first air injection tubes 32 are respectively connected to the two airbags 33, and the top ends are connected to the air source.

[0070] like Figure 9 As shown, when the camera 42 needs to be adjusted to tilt to the left, the first air inlet tube 32 on the right is activated to inflate the corresponding airbag 33. The airbag 33 expands and causes the second hose 31 to deform, which drives the camera 42 to tilt to the left, increasing the shooting range of the camera assembly 4 and achieving all-round shooting to avoid blind spots in visual monitoring. Furthermore, the first hose 21 and the second hose 31 are equipped with an explosion-proof cable 44 that is electrically connected to the camera 42. The explosion-proof cable 44 and the second air inlet tube 410 divide the interior of the second hose 31 into two chambers, left and right, for the placement of the two airbags 33, respectively, which improves the stability of the placement of the airbags 33.

[0071] In some embodiments, the top of the mounting plate 61 is also provided with an auxiliary component 7. The auxiliary component 7 includes a receiving chamber 71 located at the top of the mounting plate 61. The receiving chamber 71 is provided with a winding drum 74 inside. The top of the first hose 21 is wound around the outer surface of the winding drum 74. The receiving chamber 71 is also provided with a third driving part for driving the winding drum 74 to rotate. The winding speed of the winding drum 74 is adapted to the lifting speed of the active guide wheel 63.

[0072] like Figure 1 , Figure 3 and Figure 7 As shown, during the ascent of the first hose 21, the third drive unit can drive the winding drum 74 to rotate, winding the first hose 21 onto the winding drum 74. Compared to the first hose 21 always moving straight up and down, its internal pipeline requires more compensation length. The winding method can avoid the increased cost and safety hazards caused by excessively long lines. Optionally, the third drive unit is a third motor 73 located inside the receiving chamber 71. The output shaft of the third motor 73 is coaxially connected to the winding drum 74. Further, the outer surface of the receiving chamber 71... The device is equipped with a control module 72, which can use a combination of common display screen, control chip and smart button to control the start and stop of electrical appliances such as the first motor 55, the second motor 66, the third motor 73 and the camera 42, and can also control the supply of gas, making it convenient to use the monitoring device 2. In addition, the housing 71 is provided with a reserved hole 75, through which the first gas injection pipe 32, the second gas injection pipe 410 and the explosion-proof cable 44 can extend, ensuring the stability of the pipelines inside the housing 71 and facilitating the connection of each pipeline.
