The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 As shown, some embodiments of this application provide a sludge suction device with a first direction X and a second direction Z that are perpendicular to each other. The sludge suction device is mainly used for sludge removal in scenarios such as petrochemical tank cleaning and sedimentation tanks in waste incineration plants, improving the convenience, effect and efficiency of sludge removal.

[0027] The sludge suction device includes a main body 100, a controller 200, a telescopic rod 300, a sludge suction component 400, a sludge suction pump 700, and a pressure pump 1000.

[0028] The main body 100 is a box, tank or shell, and the main body 100 defines the containment space.

[0029] The controller 200 is located on one side of the body 100 along the first direction X. The connection method between the controller 200 and the body 100 includes any one of snap-fit, bolt connection, welding, and sliding connection, which can be specifically set according to the actual situation.

[0030] The telescopic rod 300 is disposed on one side of the body 100 along the second direction Z, and the telescopic rod 300 extends along the first direction X, that is, the axial direction of the telescopic rod 300 is parallel to the first direction X. In addition, the telescopic rod 300 is located above the body 100 along the second direction Z.

[0031] Understandably, the telescopic rod 300 can extend or retract along the first direction X.

[0032] The suction component 400 is disposed at one end of the telescopic rod 300 away from the controller 200 along the first direction X, and the suction component 400 is provided with a suction head 500 and a spray head 600 on one side along the second direction Z.

[0033] In this embodiment, the outlet end of the sludge pump 700 is provided with a discharge pipe 800, and the inlet end of the sludge pump 700 is provided with a suction pipe 900. The suction pipe 900 is at least partially inserted through the telescopic rod 300, so that the telescopic rod 300 provides a limiting and fixing function for the suction pipe 900, and the length of the suction pipe 900 can be adjusted by the telescopic rod 300 to adapt to the cleaning of sludge in different areas. By connecting the suction pipe 900 to the suction head 500, when the sludge pump 700 is running, external sludge or impurities can enter the suction pipe 900 through the suction head 500 and be discharged through the discharge pipe 800, thereby achieving sludge removal.

[0034] It should be noted that the vacuum pump 700 is electrically connected to the controller 200 so that the controller 200 can control the start, stop or operating power of the vacuum pump 700.

[0035] In addition, the pressurizing pump 1000 has an inlet pipe 1100 at its inlet end and a drain pipe 1200 at its outlet end. The drain pipe 1200 at least partially passes through the telescopic rod 300, providing a limiting and fixing function for the drain pipe 1200 and connecting it to the nozzle 600. In this embodiment, the pressurizing pump 1000 is a pump device that converts low-pressure fluid into high-pressure output through the piston area difference principle. It is mainly used in scenarios such as water heater pressurization, high-rise building water supply, solar energy systems, and water purifiers to alleviate insufficient water pressure. It should be noted that the pressurizing pump 1000 is electrically connected to the controller 200, which controls the start, stop, and pressurization level of the pressurizing pump 1000.

[0036] It is understood that in this application, the pressure pump 1000 can convert low-pressure fluid into high-pressure fluid and spray it out from the nozzle. That is, the high-pressure liquid sprayed out through the nozzle can flush and dilute the solidified sludge or sludge with low water content, and dilute the solidified sludge to form sludge with high water content.

[0037] It should be noted that the inlet pipe 1100 described in this application is used to connect with an external water source so that when the pressure pump 1000 is running, the external water source can be drawn into the inlet pipe 1100 and sprayed out from the nozzle 600 through the drain pipe 1200. The liquid sprayed out through the nozzle 600 can wash and dilute the solidified sludge, and the sludge after washing and dilution can be cleaned by the suction pump 700, thereby improving the dredging quality and dredging efficiency.

[0038] like Figure 2 As shown, in some embodiments of this application, the suction member 400 defines at least one first guide cavity (not shown) and a second guide cavity (not shown), the first guide cavity and the second guide cavity being spaced apart.

[0039] It is understandable that the number of the first guide cavity and the second guide cavity can be any number of one, two or more, depending on the actual situation.

[0040] In this embodiment, the suction pipe 900 is connected to the suction head 500 through the first guide cavity, so as to guide the sludge entering the suction device 400 through the suction head 500 through the first guide cavity, so that the sludge can enter the suction pipe 900 through the first guide cavity, and then be discharged from the drain pipe 800 by the suction pump 700.

[0041] In addition, the drain pipe 1200 is connected to the nozzle 600 through the second guide cavity, so that the liquid discharged into the nozzle 600 through the drain pipe 1200 is guided through the second guide cavity, so that the liquid can enter the nozzle 600 through the first guide cavity and be sprayed out from the nozzle 600, so as to wash and dilute the solidified sludge.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the suction device 400 includes a plurality of nozzles 600, the plurality of nozzles 600 are arranged at intervals along the edge of the suction device 400, and the plurality of nozzles 600 are centrally symmetrical about the midpoint of the suction device 400, and the nozzles 600 are spaced apart from the suction head 500.

[0043] It should be noted that by placing multiple nozzles 600 at the edge of the suction unit 400, the area covered by the suction unit 400 when flushing solidified sludge is increased, thereby improving the flushing efficiency. Furthermore, by adjusting the water pressure emitted from each nozzle 600, the suction position of the suction unit 400 can be adjusted to facilitate cleaning of sludge in different areas, thus improving the convenience and efficiency of sludge cleaning.

[0044] In some embodiments, multiple nozzles 600 are arranged at equal intervals along the edge of the suction member 400, which not only increases the area of ​​the liquid sprayed by the suction member 400 that washes away the sludge, but also allows the suction position of the suction member 400 to be adjusted by the pressure pump 1000.

[0045] For example, by controlling the liquid pressure ejected by one of the multiple nozzles 600 to be less than the liquid pressure ejected by the other nozzles 600, the suction component 400 can be moved toward the nozzle 600 with the lower liquid pressure, thereby adjusting the suction position of the suction component 400.

[0046] In addition, in some embodiments of this application, the suction device 400 includes a plurality of suction heads 500, which are arranged at intervals. By increasing the number of suction heads 500, the suction efficiency is improved.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the suction device includes a first reel 1300 and a second reel 1400, the first reel 1300 and the second reel 1400 are spaced apart, and the connection between the first reel 1300 and the second reel 1400 and the body 100 includes any one of welding, snap-fit, and bolt connection.

[0048] The first reel 1300 and the second reel 1400 are respectively disposed on the side of the body 100 facing the telescopic rod 300, and the first reel 1300 and the second reel 1400 are respectively located between the controller 200 and the telescopic rod 300.

[0049] In this embodiment, the suction pipe 900 is partially wound around the first reel 1300, so that when the telescopic rod 300 extends or retracts, the rotation of the first reel 1300 allows the suction pipe 900 to extend or retract synchronously with the telescopic rod 300, facilitating adjustment of the suction position of the suction component 400 and improving suction flexibility. Additionally, the drain pipe 1200 is partially wound around the second reel 1400, so that when the telescopic rod 300 extends or retracts, the rotation of the second reel 1400 allows the drain pipe 1200 to extend or retract synchronously with the telescopic rod 300, ensuring the stability and flexibility of external liquid ejected from the drain pipe 1200 and the nozzle 600 by the pressure pump 1000.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the body 100 is provided with a first connecting pipe 1500 on the side facing the telescopic rod 300, and the first reel 1300 is provided with a first connecting end 1310 on the side. It should be noted that the first connecting end 1310 is located in the axial direction of the first reel 1300.

[0051] One end of the first connecting pipe 1500 is connected to the first connecting end 1310 via the first guide pipe 1600, and the other end of the first connecting pipe 1500 is connected to the inlet end of the sewage pump 700. The end of the sewage suction pipe 900 away from the sewage suction head 500 is connected to the first connecting end 1310 to ensure that the pipe connected to the inlet end of the sewage pump 700 remains fixed. At the same time, it ensures that when the telescopic rod 300 extends or retracts, the first reel 1300 rotates and drives the sewage suction pipe 900 to extend or retract synchronously with the telescopic rod 300. This ensures the flexibility of the sewage suction position adjustment of the sewage suction component 400, increases the effective sewage suction area of ​​the sewage suction component 400, and improves the sewage suction efficiency.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the body 100 is provided with a second connecting pipe 1700 on the side facing the telescopic rod 300, and the second reel 1400 is provided with a second connecting end 1410 on the side. It should be noted that the second connecting end 1410 is located in the axial direction of the second reel 1400.

[0053] One end of the second connecting pipe 1700 is connected to the second connecting end 1410 via the second guide pipe 1800, and the other end of the second connecting pipe 1700 is connected to the discharge end of the pressure pump 1000. The end of the pressure pump 1000 away from the nozzle 600 is connected to the second connecting end 1410 to ensure that the pipe connected to the discharge end of the pressure pump 1000 remains fixed. At the same time, it ensures that when the telescopic rod 300 extends or retracts, the second reel 1400 rotates and drives the discharge pipe 1200 to extend or retract synchronously with the telescopic rod 300. This ensures the flexibility of adjusting the position of the nozzle 600 of the suction component 400, increases the effective suction area of ​​the suction component 400, and improves the suction efficiency.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the sludge suction device includes a first camera 1900, which is disposed on the side of the telescopic rod 300 near the sludge suction component 400. The first camera 1900 is connected to the controller 200 to capture images or videos of the body 100 along the first direction X, and send the images or videos to the controller 200. The controller 200 analyzes the location of the sludge and the area that needs to be cleaned based on the images or videos, and controls the operation of the sludge suction pump 700 and the pressure pump 1000 to control the sludge suction component 400 to suction sludge or flush and dilute the sludge, thereby improving the accuracy and efficiency of sludge removal.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments of this application, a hydraulic cylinder 2200 is provided on the side of the main body 100 facing the telescopic rod 300. The output shaft of the hydraulic cylinder 2200 is disposed away from the main body 100 along the second direction Z. The output shaft of the hydraulic cylinder 2200 is connected to the telescopic rod 300 along the second direction Z so as to adjust the height of the telescopic rod 300 along the second direction Z, thereby adjusting the height of the suction component 400 along the second direction Z, so as to facilitate cleaning sludge of different heights.

[0056] The hydraulic cylinder 2200 is connected to the controller 200 so that the controller 200 can control the start or stop of the hydraulic cylinder 2200.

[0057] For example, the suction device provided in this application can clean sludge or impurities from a tank. A first camera 1900 captures an image of the tank, and a controller 200 analyzes the tank's height. The controller then controls a hydraulic cylinder 2200 to raise the telescopic rod 300 to a preset height along the second direction Z, allowing the suction component 400 to enter the tank for cleaning the sludge inside. Furthermore, by adjusting the length of the telescopic rod 300 or the pressure of the liquid sprayed from each nozzle 600, the position of the suction component 400 within the tank can be adjusted to clean sludge from different locations within the tank, improving the ease of cleaning.

[0058] like Figure 2 As shown, in some embodiments of this application, the suction device 400 includes a second camera 2000 and a third camera 2100. The second camera 2000 is disposed on the side of the suction device 400 facing the suction head 500, and the third camera 2100 is disposed on the side of the suction device 400 away from the suction head 500.

[0059] It should be noted that the second camera 2000 and the third camera 2100 are electrically connected to the controller 200. The second camera 2000 can capture images of the side of the suction unit 400 facing the nozzle 600, that is, it can capture images of the side of the suction unit 400 facing the sludge when suctioning, and can send the captured images to the controller 200, which can then observe and identify the suction status on the side of the suction unit 400 facing the suction head 500. Conversely, the third camera 2100 can capture images of the side of the suction unit 400 away from the nozzle 600, that is, it can capture images of the side of the suction unit 400 away from the sludge when suctioning, and can send the captured images to the controller 200, which can then observe and identify the suction status on the side of the suction unit 400 away from the suction head 500, thus ensuring the quality of suction.

[0060] It should be noted that the liquid sprayed through nozzle 600 can also clean the second camera 2000 to ensure the accuracy of image acquisition by the second camera 2000.

[0061] like Figure 1 and Figure 2As shown, in some embodiments of this application, the suction device further includes a control chamber 2300, which is disposed on one side of the main body 100 along the first direction X. The controller 200 is disposed in the control chamber 2300 so that personnel can enter the control chamber 2300 and control the suction pump 700, the pressurizing pump 1000 and the telescopic rod 300 through the controller 200.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the body 100 is provided with a drive wheel on the side opposite to the telescopic rod 300 along the second direction Z, so as to facilitate the movement of the sludge suction device and improve the convenience of sludge cleaning.

[0063] like Figure 2 As shown, in some embodiments of this application, a sleeve is provided between the telescopic rod 300 and the suction component 400. This sleeve fixes the suction pipe 900 and the drain pipe 1200 together to ensure their stability during the telescopic rod 300's extension and retraction. In other words, the suction pipe 900 and the drain pipe 1200 are respectively inserted through the sleeve, and the sleeve provides a limiting effect on the suction pipe 900 and the drain pipe 1200.

[0064] like Figure 2 As shown, in some embodiments of this application, the telescopic rod 300 includes at least a first connecting rod 310 and a second connecting rod 320. The first connecting rod 310 is sleeved on the second connecting rod 320, and the first connecting rod 310 and the second connecting rod 320 are slidably connected along the first direction X, so that the second connecting rod 320 can slide relative to the first connecting rod 310.

[0065] The first connecting rod 310 defines a limiting channel, and the second connecting rod 320 is slidably connected to the inner wall of the limiting channel. The first connecting rod 310 has a first limiting member and a second limiting member at both ends along the first direction X, and the second connecting rod 320 has a third limiting member at one end of the limiting channel. The first and second limiting members respectively limit the third limiting member to prevent the second connecting rod 320 from falling out of the limiting channel, thereby ensuring the stability and smoothness of the second connecting rod 320 sliding relative to the first connecting rod 310 along the first direction X.

[0066] like Figure 2As shown, in some embodiments of this application, a third connecting rod 330 is provided at the end of the second connecting rod 320 away from the first connecting rod 310. The second connecting rod 320 is sleeved on the third connecting rod 330, and the third connecting rod 330 and the second connecting rod 320 are slidably connected along the first direction X. By increasing the number of connecting rods, the length of the telescopic rod 300 extending along the first direction X is increased, thereby increasing the cleaning range of the suction device and improving the cleaning efficiency.

[0067] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
