Description

Technical Field

[0001] This disclosure relates to the field of high-pressure reactor technology, and more specifically, to a high-pressure reactor cleaning device. Background Technology

[0002] An autoclave is a sealed container that can carry out physical or chemical reactions at pressures above atmospheric pressure. It is typically made of high-strength steel and equipped with pressure control and safety protection systems. Because autoclaves are used in high-pressure environments, their safety performance is paramount. Before being put into use, autoclaves usually undergo safety corrosion tests, and the autoclave must be cleaned before resistivity measurements are taken.

[0003] Waste liquid is generated after cleaning the autoclave. The cleaning process of the autoclave and the waste liquid disposal process are often separated. The traditional cleaning method is to use a high-pressure water pipe to rinse the autoclave body, and the waste liquid is discharged from the autoclave body by manual disposal. This method of cleaning autoclaves is prone to incomplete cleaning and waste liquid residue, causing pollution inside the autoclave, and is also time-consuming and labor-intensive.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Detailed Implementation

[0039] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0040] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0041] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0042] In related technologies, the cleaning and waste discharge of autoclaves are integral to the testing and use of autoclaves. For example, after conducting a steam corrosion test on an autoclave, the waste water needs to be poured out, and the inner wall of the autoclave body needs to be rinsed with pure water. The rinse water (waste water) is then poured out, completing routine maintenance. For instance, before the steam corrosion test, the autoclave needs to be rinsed at least three times with Class B water. After cleaning, the resistivity of the water can be measured and recorded. However, cleaning and waste discharge are often performed in separate steps. If the cleaning with pure water before the test is incomplete, the waste water can easily overflow to the surface of the autoclave and cause backflow, contaminating the inside of the autoclave and affecting the accuracy of the test results. Currently, for small-volume autoclaves, waste water can be manually poured out, while for large-volume autoclaves, the autoclave body can be raised by a motor and tilted for pouring. Manual pouring is laborious and poses safety hazards; motor-driven pouring is time-consuming and relies on motor lifting, and both methods result in waste water residue.

[0043] Based on this, the present disclosure provides a high-pressure autoclave cleaning device, such as... Figure 1 As shown, combined with Figure 2 The high-pressure autoclave cleaning device includes: a water pumping pipe assembly 100, a rotary cleaning mechanism 200, a retractable water inlet pipe 310, and a controller 400.

[0044] The pumping pipe assembly 100 includes a main pumping pipe 110 and a suction head 120. The suction head 120 is connected to one end of the main pumping pipe 110, and its bottom surface is fitted against the inner wall of the autoclave body 10. The rotary cleaning mechanism 200 includes an annular slider 210 and multiple water outlets 220. The annular slider 210 is sleeved on the main pumping pipe 110 and is slidably connected to it. The annular slider 210 can rotate around the main pumping pipe 110. The multiple water outlets 220... The components are spaced apart in the circumferential direction of the annular slider 210; one end of the retractable water inlet pipe 310 is sleeved on the outer wall of the main water inlet pipe 110, and the retractable water inlet pipe 310 is connected to the slider 210. The cleaning liquid flows into the rotary cleaning mechanism 200 through the retractable water inlet pipe 310, and the retractable water inlet pipe 310 moves synchronously with the slider 210; the controller 400 is connected to the water inlet pipe group 100 and the rotary cleaning mechanism 200 respectively, and the controller 400 is used to synchronously control the opening and closing of the water outlet 220 and the suction of the water inlet pipe group 100.

[0045] The pressure vessel cleaning device provided in this disclosure synchronously controls the water pump assembly 100 and the rotary cleaning mechanism 200 via a controller 400. This device integrates cleaning and waste liquid discharge, enabling simultaneous cleaning and waste liquid discharge of the pressure vessel, saving cleaning time and improving cleaning efficiency. The rotary cleaning mechanism 200 can perform vertical and circumferential cleaning within the pressure vessel, achieving comprehensive cleaning of the pressure vessel body, avoiding cleaning dead corners, and improving the cleanliness of the pressure vessel body. The water pump assembly 100, with a suction head 120 that fits against the inner wall of the pressure vessel body 10, can thoroughly remove waste liquid residue from the inner wall of the vessel, preventing waste liquid residue or backflow from contaminating the pressure vessel. In addition, the device is equipped with a retractable water inlet pipe 310, whose length can be adjusted to match different positions of the rotary cleaning mechanism 200, preventing the water inlet pipe from being too long and accumulating inside the vessel, causing secondary contamination.

[0046] It should be noted that the waste liquid in this disclosure refers to the liquid generated after cleaning the autoclave. This liquid can be a contaminated liquid or a liquid required for resistivity measurement. Depending on different functional requirements, the waste liquid can be the liquid generated after cleaning the autoclave with pure water or the liquid generated after cleaning the autoclave with a cleaning solution. This disclosure does not limit the specific type of waste liquid. The cleaning solution in this disclosure can refer to pure water or a liquid with cleaning function. The type of cleaning solution can be determined according to the actual cleaning requirements of the autoclave. Regardless of the type of cleaning solution and waste liquid, the device provided in this disclosure is applicable, and for waste liquids with special requirements, such as waste liquids that require resistivity measurement, the device provided in this disclosure will not cause pollution to such waste liquids when discharging them.

[0047] The various parts of the high-pressure autoclave cleaning apparatus provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings:

[0048] In the embodiments provided in this disclosure, such as Figure 1 As shown, the pressure vessel cleaning device includes a water pumping pipe assembly 100, which includes a main water pumping pipe 110 and a suction head 120. The suction head 120 is connected to one end of the main water pumping pipe 110, and the bottom surface of the suction head 120 is fitted against the inner wall of the pressure vessel body 10.

[0049] In some embodiments, the suction head 120 has an arc-shaped bottom surface, and the bottom surface of the suction head 120 dynamically fits against the inner wall of the pressure vessel body 10. Through the annular bottom surface of the suction head 120, it can form a good fit with the inner wall of the pressure vessel body, ensuring that the waste liquid at the bottom of the vessel body can be completely sucked up by the suction head 120, and no waste liquid will accumulate at the arc-shaped bottom surface of the vessel body. In addition, for the waste liquid hanging on the inner wall of the vessel body, the position of the suction head 120 can be adjusted to move the suction head 120 to the waste liquid, and the suction head 120 can also fit against the inner wall of the vessel body to suck up the waste liquid hanging on the wall, so as to perform all-round suction of waste liquid on the inner wall of the vessel body.

[0050] The suction head 120 is movably connected to one end of the main water pipe 110 to improve the fit between the suction head 120 and the inner wall of the pressure vessel. For example, the suction head 120 and the main water pipe can be hinged. When changing the position of the suction head 120, the position of the main water pipe 110 can remain unchanged or be slightly adjusted, thus adjusting the position of the suction head 120. Because the main water pipe 110 is relatively long and the space inside the pressure vessel is limited, it is not easy for the main water pipe 110 to move significantly inside the pressure vessel. However, since the suction head 120 is movably connected to one end of the main water pipe 110, the flexibility of the suction head 120 can be improved, achieving comprehensive suction of the inside of the pressure vessel 10 and preventing waste liquid residue.

[0051] In some embodiments, such as Figure 3 As shown, combined with Figure 1 The suction head 120 has multiple spaced suction tubes 121 on its arc-shaped bottom surface. Each suction tube 121 is connected to the main water pipe 110 through the suction head 120, and each suction tube 121 is connected to the bottom surface of the suction head 120 by a spring 122. The arc-shaped bottom surface of the suction head 120 is equipped with several small-diameter suction tubes 121 with springs 122. After the bottom of each suction tube 121 contacts the bottom surface of the vessel, the spring 122 adjusts the fit between the suction tube 121 and the bottom surface of the vessel. Springs 122 not in contact with the bottom surface of the vessel are fully released, allowing the small-diameter suction tube 121 to contact the bottom surface of the vessel. Springs 122 in contact with the bottom surface of the vessel are compressed and contracted, ensuring contact between the small-diameter suction tube 121 and the bottom surface of the vessel. By supplementing the suction of waste liquid through multiple small-diameter suction tubes 121, the device can completely absorb the liquid accumulated in the vessel, further reducing the amount of waste liquid remaining in the vessel. Similarly, for the inner wall of the vessel, the suction head 120 can also dynamically fit with the inner wall of the vessel through the suction tube 121, which will not be repeated here.

[0052] In some embodiments, the main water pumping pipe 110 can be made of rigid material, such as stainless steel, to prevent corrosion from corrosive liquids and improve its durability. In other embodiments, the main water pumping pipe 110 can be made of flexible material, such as plastic hose, to improve its positional flexibility within the autoclave. The specific material of the main water pumping pipe 110 can be determined according to the actual design requirements of the device, and this disclosure does not impose specific limitations.

[0053] In some embodiments, the radius of curvature of the arc-shaped bottom surface of the suction head 120 can be 50mm to 80mm, for example, it can be 50mm, 55mm, 60mm, 65mm, 70mm, 75mm or 80mm, etc., to improve the fit between the arc-shaped bottom surface of the suction head 120 and the inner wall of the vessel.

[0054] In some embodiments, such as Figure 3 As shown, a liquid level sensor 311 is also provided on the suction head 120. The liquid level sensor 311 is connected to the controller 400 to monitor the waste liquid residue on the inner wall of the autoclave body 10 in real time, thereby improving the intelligence of the device and eliminating the need for manual observation of the waste liquid residue on the inner wall of the autoclave body. In addition, the setting of the liquid level sensor 311 improves the applicability of the device, that is, the device can be applied to autoclaves of various volumes and models.

[0055] In the embodiments provided in this disclosure, such as Figure 4 As shown, combined with Figure 1 The high-pressure autoclave cleaning device includes a rotary cleaning mechanism 200, which includes an annular slider 210 and multiple water outlets 220. The annular slider 210 is sleeved on the main water pumping pipe 110 and is slidably connected to the main water pumping pipe 110. The annular slider 210 can rotate around the main water pumping pipe 110. The multiple water outlets 220 are distributed at intervals in the circumferential direction of the annular slider 210.

[0056] The annular slider 210 and the main water pipe 110 can slide or rotate relative to each other, allowing the annular slider 210 to move up and down inside the vessel to clean the inner wall of the vessel at different heights. The annular slider 210 can also rotate inside the vessel to perform 360° circumferential cleaning of the inner wall of the vessel. The rotating cleaning mechanism 200 can achieve all-round cleaning of the inner wall of the high-pressure vessel.

[0057] An annular slider 210 is fitted onto the main water intake pipe 110. The main water intake pipe 110 provides support for the annular slider 210 and limits its displacement, ensuring the accuracy of its position and avoiding repeated cleaning of the same parts of the vessel, thus improving cleaning efficiency. The annular slider 210 is connected to the water inlet pipe. The cleaning fluid enters the channel inside the annular slider 210 through the water inlet pipe and the water inlet on the annular slider 210, flowing until it reaches the water outlet 220. To ensure the cleaning fluid has sufficient pressure at the water outlet 220 and can be sprayed to a preset position, a pressurization structure can be installed at the water inlet of the annular slider 210 or the outlet of the water inlet pipe to increase the pressure of the cleaning fluid at the water outlet 220, ensuring the cleaning effect of the cleaning fluid.

[0058] In some embodiments, such as Figure 4 and Figure 5 As shown, multiple water outlets 220 are arranged side by side. The water outlet range of each water outlet 220 is radiating outward at a 60° angle with the axis of the water outlet 220 as the center. That is, in the horizontal direction, the water outlet coverage angle of each water outlet 220 can be 120°, and in the vertical direction, the water outlet coverage angle of each water outlet 220 can be 120°. This ensures comprehensive cleaning of the inner wall of the vessel and also prevents the cleaning liquid from overflowing outside the vessel and causing backflow and pollution.

[0059] In some embodiments, such as Figure 6 As shown, multiple water outlets 220 are arranged in two groups, one above the other, along the axial direction of the annular slider 210. These two groups of water outlets 220 are staggered. The diameter of each water outlet 220 in the upper group is greater than or equal to the diameter of each water outlet 220 in the lower group. This arrangement of the water outlets 220 allows the annular slider 210 to reach the opening of the vessel body when it is a certain distance away from the vessel opening. This shortens the moving distance of the annular slider 210. While ensuring the cleaning effect, the reduced moving distance or number of movements of the annular slider 210 prevents detachment or breakage at pipe connections due to the movement of the annular slider 210, thus improving the reliability and durability of the device.

[0060] In some specific embodiments, the diameter of each water outlet 220 in the upper group can be 0.8mm to 1.2mm, for example, 0.8mm, 0.9mm, 1.0mm, 1.1mm or 1.2mm, etc.; the diameter of each water outlet 220 in the lower group is 0.5mm to 0.8mm, for example, 0.5mm, 0.6mm, 0.7mm or 0.8mm, etc.

[0061] In some embodiments, the rotary cleaning mechanism 200 further includes a drive structure 700, which drives the annular slider 210 to rotate and slide simultaneously, or drives the annular slider 210 to rotate only, or drives the annular slider 210 to slide only.

[0062] like Figure 7 As shown, the drive structure 700 includes at least a drive motor 710 and a bearing 720. The drive motor 710 is connected to the annular slider 210, and the bearing 720 is disposed between the annular slider 210 and the main water pipe 110. The drive motor 710 can drive the annular slider 210 to rotate or slide, so that the annular slider 210 moves to a preset position. The drive motor 710 can be connected to a controller 400, which can control the start, stop, and speed of the drive motor 710 to control the movement direction and speed of the annular slider 210. In addition, the controller 400 can collect movement feedback of the annular slider 210 to adjust the power of the drive motor 710 in real time, so that the power of the drive motor 710 is matched with the movement of the annular slider 210. Of course, the drive structure 700 may also include other structures or components necessary for driving the annular slider 210 to move. Although these necessary components are not listed in this disclosure, it should be understood that these necessary components are available in the art or can be obtained with conventional modifications, and this disclosure does not make any specific limitations.

[0063] In some embodiments, such as Figure 8 As shown, the rotary cleaning mechanism 200 also includes a ratchet positioning structure 730, which is disposed on the inner wall of the annular slider 210 to fix the slider 210 to the main water pipe 110. When the annular slider 210 slides to a preset position on the main water pipe 110, the ratchet positioning structure 730 can fix the annular slider 210 to the main water pipe 110. However, the ratchet positioning structure 730 does not limit the rotation of the annular slider 210. By fixing the annular slider 210 to the main water pipe 110 through the ratchet positioning structure 730, the fixed position on the inner wall of the autoclave can be cleaned in a more thorough manner to further improve the cleanliness of the autoclave. After the annular slider 210 has performed focused cleaning on a specific area, the positioning effect of the ratchet positioning structure 730 on the annular slider 210 can be released, and the annular slider 210 can slide again.

[0064] In the embodiments provided in this disclosure, such as Figure 1 and Figure 2As shown, the high-pressure autoclave cleaning device includes a retractable water inlet pipe 310. One end of the retractable water inlet pipe 310 is sleeved on the outer wall of the main water pumping pipe 110, and the retractable water inlet pipe 310 is connected to the slider 210. The cleaning liquid flows into the rotary cleaning mechanism 200 through the retractable water inlet pipe 310, and the retractable water inlet pipe 310 and the slider 210 move synchronously.

[0065] The retractable inlet pipe 310 is connected to multiple outlet holes 220 on the slider 210. The cleaning fluid flows through the retractable inlet pipe 310 and the outlet holes 220 on the slider 210, thereby cleaning the inner wall of the autoclave body 10. One end of the retractable inlet pipe 310 is fitted onto the outer wall of the main pumping pipe 110. When the slider 210 slides on the main pumping pipe 110 towards the bottom wall of the autoclave body, one end of the retractable inlet pipe 310 moves synchronously with the slider 210, increasing the length of the retractable inlet pipe 310 fitted onto the main pumping pipe 110. When the slider 210 slides on the main pumping pipe 110 away from the bottom wall of the autoclave body, one end of the retractable inlet pipe 310 moves synchronously with the slider 210, decreasing the length of the retractable inlet pipe 310 fitted onto the main pumping pipe 110.

[0066] In some embodiments, the total length of the retractable inlet pipe 310 can be greater than or equal to the total length of the main drain pipe 110, so that the retractable inlet pipe 310 can completely cover the outer wall of the main drain pipe 110 at its maximum extension, so as to meet the waste liquid discharge requirements of the device.

[0067] In the embodiments provided in this disclosure, such as Figure 9 and Figure 10 As shown, the autoclave cleaning device also includes a storage structure 500, which is connected to the end of the retractable water inlet pipe 310 away from the main water pump pipe 110. The storage structure 500 can be used to adjust the extension and retraction of the retractable water inlet pipe 310 and to store the part of the retractable water inlet pipe 310 that is sleeved outside the main water pump pipe 110, so as to avoid damage caused by tangling between pipes or wires.

[0068] The autoclave cleaning device may also include a drain pipe 320. Waste liquid flows through the main pumping pipe 110 and then through the drain pipe 320 to be discharged outside the device. The storage structure 500 can also be used to store the drain pipe 320. The drain pipe 320 can also be extended or retracted in length through the storage structure 500.

[0069] The storage structure 500 includes a first cavity 511 and a second cavity 512 stacked together, as well as a first cylindrical rotating disk 521 and a second cylindrical rotating disk 522 stacked together and isolated from each other. The first cylindrical rotating disk 521 is located in the first cavity 511, and the second cylindrical rotating disk 522 is located in the second cavity 512. The retractable water inlet pipe 310 is connected to the first cylindrical rotating disk 521, and the drain pipe 320 is connected to the second cylindrical rotating disk 522. The first cylindrical rotating disk 521 and the second cylindrical rotating disk 522 are isolated from each other. Under the premise that the storage structure 500 can store the retractable water inlet pipe 310 and the drain pipe 320, interference between the water inlet and the water outlet of the device is avoided, which would affect the effect of high pressure autoclave cleaning and waste liquid discharge.

[0070] In some embodiments, the first cylindrical rotating disk 521 and the second cylindrical rotating disk 522 can be isolated by a sealing structure such as a sealing ring or sealing ring to ensure that there is no leakage after seepage. Of course, the isolation method between the first cylindrical rotating disk 521 and the second cylindrical rotating disk 522 is not limited to a sealing structure, but can also be other mechanical structures that can be used for isolation, and this disclosure does not make specific limitations.

[0071] The retractable water inlet pipe 310 is coiled around the outer wall of the first cylindrical rotating disk 521, and the other end of the retractable water inlet pipe 310 is connected to the end of the first cylindrical rotating disk 521. The cleaning fluid flows into the retractable water inlet pipe 310 through the first cylindrical rotating disk 521. A positioning structure such as a spring clip or a buckle can also be provided on the first cylindrical rotating disk 521, which allows the retractable water inlet pipe 310 to automatically retract into the first cavity 511 after use.

[0072] The storage structure 500 may further include a first motor 531, which is connected to a first cylindrical rotating disk 521. The first motor 531 drives the first cylindrical rotating disk 521 to rotate, thereby extending or retracting the retractable water inlet pipe 310. The first motor 531 may be mounted on the side wall of the first cavity 511 and connected to a controller 400. The controller 400 can control the operation of the first motor 531 according to the device's operational requirements, causing the first motor 531 to drive the first cylindrical rotating disk 521 to rotate clockwise or counterclockwise, thus extending or retracting the retractable water inlet pipe 310. Of course, the first motor 531 can also be used in conjunction with the aforementioned positioning structure to further improve the reliability of the device's operation.

[0073] One end of the drain pipe 320 is connected to one end of the main pumping pipe 110. The drain pipe 320 is coiled around the outer wall of the second cylindrical rotating disk 522, and the other end of the drain pipe 320 is connected to the end of the second cylindrical rotating disk 522. Waste liquid is discharged through the second cylindrical rotating disk 522. A positioning structure such as a snap ring or a buckle can also be provided on the second cylindrical rotating disk 522, which allows the drain pipe 320 to automatically retract into the second cavity 512 after use.

[0074] The storage structure 500 also includes a second motor 532, which is connected to a second cylindrical rotating disk 522. The second motor 532 drives the second cylindrical rotating disk 522 to rotate, thereby extending or shortening the drain pipe 320. The second motor 532 can be mounted on the side wall of the second cavity 512 and is connected to a controller 400. The controller 400 can control the operation of the second motor 532 according to the device's operational requirements, causing the second motor 532 to drive the second cylindrical rotating disk 522 to rotate clockwise or counterclockwise, thus extending or shortening the drain pipe 320. Of course, the second motor 532 can also be used in conjunction with the aforementioned positioning structure to further improve the reliability of the device's operation.

[0075] Furthermore, since the device includes multiple motors and a controller 400, and the motors need to be connected to their respective components or structures via wires in order to control the movement of their respective components or structures, the storage structure 500 may also include a wire receiving cavity. The wire receiving cavity may be set separately in an independent cavity, or it may be integrated into the first cavity 511 or the second cavity 512. The specific location of the wire receiving cavity may be determined according to the specific design requirements of the storage structure 500, and this disclosure does not make any specific limitations.

[0076] In some embodiments, the retractable water inlet pipe 310, the drain pipe 320, and the wires can all be made of flexible materials so that they can be coiled in their respective cavities, thereby reducing the overall size of the device and improving its portability.

[0077] In the embodiments provided in this disclosure, such as Figure 1 As shown, the autoclave cleaning device includes a controller 400, which is connected to the water pumping pipe group 100 and the rotary cleaning mechanism 200 respectively, and is used to synchronously control the opening and closing of the water outlet 220 and the suction of the water pumping pipe group 100.

[0078] The controller 400 can be electrically or communicatively connected to the first motor 531, the second motor 532, and the drive motor 710, respectively. The controller 400 can control each drive component to operate according to predetermined conditions. For example, to improve the cleaning and waste liquid discharge efficiency of the autoclave, the controller 400 can simultaneously control the opening of the water outlet 220 and control the drive motor 710 to move the slider 210 up and down, thereby achieving comprehensive cleaning of the inner wall of the autoclave body 10. At the same time, the controller 400 can also control the suction head 120 to suction the waste liquid from the inner wall of the autoclave, thereby achieving waste liquid discharge.

[0079] The controller 400 can also collect and monitor the residual status of waste liquid in real time through the liquid level sensor 311. The controller 400 can also visualize the cleaning status of the inner wall of the autoclave 10, allowing the operator to adjust parameters such as the cleaning position, cleaning fluid volume, and cleaning fluid pressure based on the cleaning progress to achieve the preset cleaning state. Furthermore, the controller 400 may include an alarm or other structure for alerting the device's status. For example, if one or more components of the device are damaged or malfunction, the alarm can sound to serve as a warning.

[0080] In addition, the controller 400 can also adjust the opening and closing of the water outlet 220 and the suction of the water pumping pipe assembly 100 in real time according to the residual waste liquid and the flow rate of the cleaning fluid. For example, at the beginning of the cleaning process, since there is little residual waste liquid, the rotary cleaning mechanism 200 can be controlled to work before the water pumping pipe assembly 100. When the residual waste liquid increases to a preset amount, the controller 400 controls the rotary cleaning mechanism 200 and the water pumping pipe assembly 100 to work synchronously. At the end of the cleaning process, since there is a lot of residual waste liquid, the rotary cleaning mechanism 200 can be controlled to stop working before the water pumping pipe assembly 100, extending the working time of the water pumping pipe assembly 100. When the residual waste liquid decreases to a preset amount, the controller 400 controls the water pumping pipe assembly 100 to stop working.

[0081] It should be noted that the controller 400 provided in this disclosure is used to synchronously control the opening and closing of the water outlet 220 and the suction of the water pumping pipe group 100. Synchronization is not a strict synchronization. There can be a certain time difference between the opening and closing of the water outlet 220 and the suction of the water pumping pipe group 100. Within this time difference, the preset cleaning effect and the preset waste liquid discharge effect can be achieved, and both can be considered to be working synchronously.

[0082] In the embodiments provided in this disclosure, reference is made again. Figure 2The autoclave cleaning device also includes a folding support 600. The first end of the folding support 600 is connected to the end of the main water pipe 110 furthest from the suction head 120. The second end of the folding support 600 can unfold in an umbrella shape with the first end as its center point. The second end of the folding support 600 is connected to the edge of the autoclave body 10. During use, the folding support 600 provides support and a fixing point for the device, preventing movement during operation and ensuring effective cleaning.

[0083] In some embodiments, the folding support 600 may include a plurality of support rods, one end of which is hinged to the end of the main pumping pipe 110 away from the suction head 120, allowing each support rod to rotate about this end. When the folding support 600 is open, the plurality of support rods form an angle with the main pumping pipe 110, resulting in an umbrella-like structure. When the folding support 600 is retracted, the plurality of support rods are parallel to the main pumping pipe 110. The folding support 600 enables the device to be fixed on the edge of the autoclave body, improving the stability and reliability of the device during operation.

[0084] In addition, the device may include multiple support parts. For example, a support part may be provided at the controller 400 to fix the working position of the controller 400. Of course, the support parts may also be provided in different parts of the device as needed to meet the working requirements of the device.

[0085] It should be noted that the pressure vessel cleaning device provided in this disclosure does not limit the opening position and direction of the pressure vessel body; that is, it is applicable whether the pressure vessel body is vertical, horizontal, or inclined. Furthermore, it is applicable to both large and small-volume pressure vessels. This pressure vessel cleaning device has a wide range of applications and strong applicability.
