Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning tool for a reaction kettle. Background Art

[0002] Most current vertical reactors are equipped with a stirring paddle for agitating the reactants. The paddle's rotating shaft extends upward from the bottom of the reactor's inner wall and is usually parallel to the reactor's central axis, preventing interference with the addition of reactants and ensuring uniform agitation. The reactor's opening is located at the center of its upper end. When a user subsequently uses a nozzle to clean the reactor's inner wall, the nozzle will encounter the paddle during its descent. This requires the nozzle to remain suspended above the paddle when cleaning a reactor equipped with a paddle. The nozzle's jet, obstructed by the paddle, struggles to fully clean the reactor's inner wall below, leading to issues such as incomplete cleaning and suboptimal cleaning results.

[0027] Reference Figure 1 and Figure 2According to an embodiment of the present invention, a reactor cleaning tool is provided, which includes a frame 100 and a bending device 200, wherein the frame 100 is provided with a driving assembly 110 and a lifting assembly 120, the driving assembly 110 includes a first driving member 111 and a slide rail 112, the slide rail 112 is arranged in a vertical direction, the first driving member 111 and the slide rail 112 are connected to drive the slide rail 112 to move to directly above the reactor, optionally, the first driving member 111 can drive the slide rail 112 to move from the upper side of the reactor to directly above, or from the lower side of the reactor to directly above, or descend from a high position to directly above.

[0028] The lifting assembly 120 includes a second drive member 121 and a slide 122. The second drive member 121 is mounted on the slide rail 112, and the slide 122 is slidably connected to the slide rail 112. The second drive member 121 is connected to the slide 122 to drive the slide 122 to move along the slide rail 112 (i.e., in the vertical direction). The frame 100 is equipped with a hose 131, which is connected to an external water source. Optionally, a drag chain is provided on one side of the slide rail 112, and the drag chain is installed on the frame 100 to protect the pipeline circuit connecting the various components of the cleaning tool.

[0029] The bending device 200 is mounted on the slide 122. The bending device 200 includes an outer tube assembly 210 and a third drive member 220. The outer tube assembly 210 is provided with a limiting channel 211. The hose 131 is passed through the limiting channel 211 and is connected to a nozzle 300. Optionally, the nozzle 300 can be a common nozzle such as a shower nozzle or a high-pressure nozzle, or a three-dimensional nozzle with better cleaning efficiency. The end of the outer tube assembly 210 close to the nozzle 300 can rotate relative to the end of the bending device 200 close to the slide 122. The third drive member 220 is connected to the outer tube assembly 210 to drive the end of the outer tube assembly 210 close to the nozzle 300 to rotate and bend. The outer tube assembly 210 drives the hose 131 to bend, thereby changing the original vertical running trajectory of the nozzle 300 at the end of the hose 131, so that the horizontal position and vertical position of the nozzle in the reactor are adjustable.

[0030] It is understandable that when the cleaning tool is not working, the first driving member 111 can drive the slide rail 112 away from the upper side of the reactor, driving the slide 122 and the bending device 200 to leave the top of the reactor, so as to facilitate the filling of the reactor with reactants or the sealing of the cleaning port. When the cleaning tool is working, the first driving member 111 first lowers the slide rail 112 to the top of the reactor, so that the slide 122 and the bending device 200 move to the reactor port above the reactor, and the second driving member 121 then drives the slide 122 to descend. Under the guidance of the slide rail 112, the slide 122 drives the bending device 200 to move in a straight line in the vertical direction, so that the outer tube assembly 210 of the bending device 200 and the hose 131 and the nozzle 300 on the outer tube assembly 210 enter the reactor through the reactor port for cleaning.

[0031] By setting up the bending device 200, after the nozzle 300 cleans the inner wall above the stirring paddle in the reactor, the third driving member 220 of the bending device 200 drives the outer tube assembly 210 to rotate and bend at one end close to the nozzle 300, thereby driving the hose 131 to bend, causing the nozzle 300 to shift relative to the hard tube assembly, and the slide 122 continues to descend, so that the displaced nozzle 300 and the hose 131 avoid the stirring paddle and clean the inner wall of the reactor below the stirring paddle, ensuring that the nozzle 300 fully cleans the inner wall of the reactor, improving the cleaning efficiency, and enhancing the cleaning effect.

[0032] It should be noted that the slide rail 112 is equipped with two proximity switches, spaced vertically apart. The slide 122 is provided with a sensor plate on the side facing the slide rail 112, located between the two proximity switches. The proximity switches sense the position of the slide 122 through the sensor plate, thereby controlling the start or stop of the second drive member 121. The proximity switches and sensor plate limit the range of movement of the slide 122, preventing it from exceeding its limits and causing impact or even detachment from the slide rail 112, thus providing protection for the slide 122.

[0033] Preferably, the second driving member 121 can be configured as a winch driven by a motor 222. The winch's wire rope is mounted on the frame 100, and the slide 122 is mounted on the wire rope. By retracting and extending the wire rope, the slide 122 can be driven to move up and down. Using a winch with a wire rope to drive the slide 122 can simplify the structure of the lifting assembly 120 while increasing the lifting height of the slide 122 to accommodate slide rails 112 and hoses 131 of different heights.

[0034] Optionally, the second driving member 121 may also be a linear motion module such as a cylinder, an electric push rod, a ball screw, etc. provided on the slide rail 112, which will not be described in detail here.

[0035] Reference Figure 2 As shown, it can be understood that the frame 100 is provided with a base 140, which is a plate with holes opened at the corners. The frame 100 is installed on a working area such as the outer wall of the reactor or the ground through the base 140.

[0036] The drive assembly 110 also includes a first rotating frame 113 and a second rotating frame 114 arranged in parallel. Optionally, the first rotating frame 113 and the second rotating frame 114 are configured as a high-strength frame structure made of alloy parts such as steel, aluminum, and stainless steel. The first driving member 111 is rotatably connected to the base 140, and the output end of the first driving member 111 is rotatably connected to the first rotating frame 113. The first rotating frame 113 is rotatably connected to the frame 100 and the slide rail 112, respectively. The second rotating frame 114 is located above the first rotating frame 113, and the second rotating frame 114 is rotatably connected to the frame 100 and the slide rail 112, respectively. Optionally, the first driving member 111 can be a linear motion module with telescopic components such as a cylinder and an electric push rod, which will not be described in detail here.

[0037] When the output end of the first driving member 111 is retracted, it can drive the first rotating frame 113 to rotate and drive the slide rail 112 to move downward toward the kettle mouth of the reactor, thereby achieving the alignment of the hard tube assembly and the kettle mouth; when the output end of the first driving member 111 is extended, it can drive the first rotating frame 113 to rotate and drive the slide rail 112 to move upward toward the side of the reactor, so that the cleaning tool leaves the space directly above the kettle mouth.

[0038] By setting the first rotating frame 113 and the second rotating frame 114, the first rotating frame 113 and the second rotating frame 114 form a connecting rod structure between the slide rail 112 and the frame 100, so that the slide rail 112 can be extended and moved to the top of the kettle mouth, and can also be retracted and stored above the side of the kettle mouth, simplifying the structure of the drive component 110 and effectively improving the movement stability of the slide rail 112.

[0039] In some embodiments, the end of the first rotating frame 113 away from the slide rail 112 is also connected to a counterweight wheel 115. The counterweight wheel 115 can balance the weight of the slide rail 112, the slide 122 and the nozzle 300, reduce the load of the first driving member 111, and effectively improve the structural rationality of the cleaning device.

[0040] Preferably, the frame 100 is provided with a rotatable hose reel 130, which is driven to rotate by a second motor. The hose reel 130 is located on the side of the slide rail 112 away from the slide 122. The second motor is electrically connected to the first drive member 111, the second drive member 121 and the third drive member 220 respectively. The hose 131 is wound around the hose reel 130. One end of the hose 131 is located on the hose reel 130 and is connected to an external water source, and the other end passes through the limiting channel 211 of the outer tube assembly 210 and is connected to the nozzle 300.

[0041] By providing a second motor-driven hose reel 130, the hose reel 130 can drive the hose 131 to move synchronously with the movement of the slide rail 112, slide 122, or hard tube assembly, or independently retract and extend the hose 131, thereby controlling the height of the nozzle 300. This facilitates the storage of the hose 131 while improving the coordination between the hose 131 and the outer tube assembly 210, preventing problems such as strain and damage to the hose 131 caused by the outer tube assembly 210 forcibly pulling on the hose 131.

[0042] Reference Figure 1 and Figure 3 As shown, it is understood that the outer tube assembly 210 includes a first rigid tube 212, a second rigid tube 213, and a rotating connector 214. Optionally, the first rigid tube 212 and the second rigid tube 213 can be made of rigid parts such as alloys, hard plastics, etc. The rotating connector 214 is a channel-shaped structure formed by connecting three plates. The center hole of the first rigid tube 212, the center hole of the second rigid tube 213, and the channel-shaped rotating connector 214 combine to form a limiting channel 211 for the hose 131 to pass through.

[0043] One end of the first hard tube 212 is connected to the slide 122, and the other end is rotatably connected to the rotating connector 214. The second hard tube 213 is located below the first hard tube 212 and is fixedly connected to the rotating connector 214. Specifically, the rotating connector 214 is rotatably connected to the first hard tube 212 through a first pin shaft 2142 passing through the first hard tube 212, and is fixedly connected to the second hard tube 213 through at least two second pin shafts 2143 passing through the second hard tube 213.

[0044] The rotating connector 214 includes a connecting portion 2141 that protrudes away from the slide rail 112. The third driving member 220 is rotatably connected to the connecting portion 2141 to drive the rotating connector 214 and the second rigid tube 213 to rotate relative to the first rigid tube 212. Specifically, the third driving member 220 drives the rotating connector 214 to rotate via the connecting portion 2141. The rotating connector 214 uses the first pin 2142 as a fulcrum to drive the second rigid tube 213 to rotate relative to the first rigid tube 212, thereby bending the outer tube assembly 210. At this time, the hose 131 in the second rigid tube 213 is bent relative to the hose 131 in the first rigid tube 212.

[0045] The outer tube assembly 210 is configured to include a first hard tube 212, a second hard tube 213 and a rotating connector 214. On the one hand, the first hard tube 212 and the second hard tube 213 cooperate to guide the movement of the hose 131, thereby preventing the hose 131 from tilting or twisting during movement, thereby improving the installation stability of the hose 131. On the other hand, the first hard tube 212, the second hard tube 213 and the rotating connector 214 have a simple structure and are easy to install, which can effectively simplify the structure of the outer tube assembly 210 and reduce the cost of the outer tube assembly 210.

[0046] Reference Figure 3 As shown, it can be understood that the third driving member 220 includes a support seat 221, a motor 222, a worm 223 and a rotating rod 224, the support seat 221 is connected to the first hard tube 212, the motor 222 is installed on one side of the support seat 221, the output shaft of the motor 222 is provided with a worm gear, the worm 223 is vertically arranged and installed on the support seat 221, and the worm 223 is connected to the motor 222 through engagement with the worm gear, one end of the rotating rod 224 is rotatably connected to the end of the worm 223, and the other end is rotatably connected to the connecting part 2141.

[0047] The motor 222 drives the worm 223 to rotate, which then moves up and down relative to the support base 221 and drives the rotating connector 214 to rotate via the rotating rod 224 and the connecting portion 2141, thereby driving the hose 131 to bend. By providing the worm 223, on the one hand, the user can control the rotation angle of the rotating connector 214 by controlling the number of revolutions of the worm 223, thereby precisely controlling the tilt angle of the second rigid tube 213 and effectively improving the control accuracy of the bending device 200. On the other hand, the longer length of the worm 223 can significantly expand the tilt angle range of the second rigid tube 213, thereby expanding the offset distance range of the nozzle 300 relative to the first rigid tube 212, adapting to reactor stirring paddles of different sizes and structures, and improving the practicality of the cleaning device.

[0048] Preferably, a first avoidance portion 2121 is provided at one end of the first hard tube 212 close to the second hard tube 213, and a second avoidance portion 2131 is provided at one end of the second hard tube 213 close to the first hard tube 212. The first avoidance portion 2121 and the second avoidance portion 2131 cooperate to avoid the hose 131. Specifically, the first avoidance portion 2121 is a hollow structure provided on the side of the first hard tube 212 facing the connecting portion 2141, and the second avoidance portion 2131 is a hollow structure provided on the side of the second hard tube 213 facing the connecting portion 2141.

[0049] When the second rigid tube 213 rotates, the hose reel 130 will continue to release part of the hose 131, so that the hose 131 extends relative to the second rigid tube 213 and enters under the stirring paddle. At this time, the bent part of the hose 131 between the first rigid tube 212 and the second rigid tube 213 will produce local bending deformation due to the squeezing of the first rigid tube 212 and the second rigid tube 213.

[0050] By setting the first avoidance portion 2121 and the second avoidance portion 2131, the first avoidance portion 2121 and the second avoidance portion 2131 can allow the curved hose 131 to partially pass through, thereby increasing the bending radius of the deformed portion of the hose 131 and reducing the stress exerted on the hose 131 at this location, thereby preventing the locally curved portion of the hose 131 from pressing against the inner wall of the first hard tube 212 and the inner wall of the second hard tube 213 after the second hard tube 213 rotates, thereby preventing problems such as jet instability and damage to the first hard tube 212 and the second hard tube 213, thereby further improving the structural rationality of the outer tube assembly 210.

[0051] Reference Figure 3 As shown, it is understood that the rotating connector 214 is provided with a first guide wheel 2144 that mates with the hose 131. Specifically, the middle portion of the first guide wheel 2144 is recessed inward to form an annular groove. The groove, in a cross-section passing through the centerline of the first guide wheel 2144, has an arc shape corresponding to the hose 131, thereby ensuring a sufficient contact area between the first guide wheel 2144 and the hose 131. The first guide wheel 2144 is rotatably mounted on the rotating connector 214, and the first guide wheel 2144 and the connecting portion 2141 are located on the same side of the second avoidance portion 2131. In some embodiments, the first guide wheel 2144 can be provided independently of the connecting portion 2141, or it can be directly rotatably connected to the connecting portion 2141, which will not be further described here.

[0052] By providing the first guide wheel 2144, when the second rigid tube 213 rotates and the hose reel 130 retracts or releases the hose 131, the first guide wheel 2144 can guide the curved portion of the hose 131 into the second rigid tube 213, or guide the hose 131 away from the second rigid tube 213 and into the first and second escape portions 2121 and 2131. This prevents interference between the curved end faces of the hose 131 and the second rigid tube 213, which could cause the hose 131 to get stuck, or friction or jamming with the second rigid tube 213, effectively improving the movement stability of the hose 131.

[0053] Reference Figure 3 and Figure 4 As shown, it can be understood that two second guide wheels 2132 are provided at one end of the second hard tube 213 away from the first hard tube 212, and a gap is formed between the two second guide wheels 2132 for the hose 131 to pass through. The structure of the second guide wheel 2132 can refer to the previous description of the first guide wheel 2144 and will not be repeated here.

[0054] By providing two second guide wheels 2132, the two second guide wheels 2132 can clamp the hose 131 and guide the hose 131 into or out of the second rigid tube 213. When the second rigid tube 213 is tilted, the end surfaces of the hose 131 and the second rigid tube 213 are prevented from being pressed against each other and bending, thereby leaving creases. This further improves the movement stability of the hose 131 and extends the service life of the hose 131. Optionally, the second guide wheels 2132 can be rotatably connected to the second rigid tube 213 to reduce friction on the hose 131.

[0055] Reference Figure 4 As shown, it can be understood that an anti-fall device 132 is provided at the end of the hose 131, and the nozzle 300 is hung on the anti-fall device 132 through a hanging rope. Optionally, the hanging rope is a steel wire rope or a rubber rope provided at the end of the nozzle 300. The hanging rope is detachably connected to the nozzle 300. After the user connects the hose 131 and the nozzle 300, the hanging rope can be installed on the anti-fall device 132. When the hose 131 is connected to the nozzle 300, the hanging rope is in a relaxed state. By providing the anti-fall device 132 to mount the nozzle 300, even if the hose 131 and the nozzle 300 are separated during the cleaning process, the hanging rope can still pull the nozzle 300 to prevent the nozzle 300 from falling into the interior of the reactor and causing damage.

[0056] Reference Figure 5 As shown, it can be understood that the slide 122 is provided with two clamping blocks 1221, which are arranged opposite to each other and are detachably connected. Optionally, one side of one clamping block 1221 can be integrally formed with the corresponding side of the other clamping block 1221, and the other side can be screwed or clamped to the corresponding side of the other clamping block 1221. The two clamping blocks 1221 can also be independently provided, and the opposite sides of the two clamping blocks 1221 can be detachably connected by screwing or clamping. A positioning hole for mounting the first rigid tube 212 is formed between the two clamping blocks 1221, and the inner wall of the positioning hole abuts the outer wall of the hose 131.

[0057] In some embodiments, the hose 131 can be set as a non-circular polygonal tube or a flat tube. In this case, the positioning hole can be set on one of the clamping blocks 1221, or it can be formed by the groove structure on the two opposite side walls of the two clamping blocks 1221; the hose 131 can also be set as a circular tube. In this case, the positioning hole is formed by the semicircular groove structure on the two opposite side walls of the two clamping blocks 1221.

[0058] The first rigid tube 212 is clamped and fixed by two detachably connected clamping blocks 1221. While ensuring the stable installation of the bending device 200, it is convenient for the user to adjust the installation angle of the first rigid tube 212, thereby changing the position of the second rigid tube 213 after rotation. The first rigid tube 212 rotating around the vertical axis and the second rigid tube 213 rotating around the first pin 2142 cooperate to adjust the position of the nozzle 300 in multiple directions, so that the nozzle 300 can pass through stirring paddles of different types and sizes, further expanding the scope of application of the cleaning tool. In addition, the connection structure between the support seat 221 and the first rigid tube 212 mentioned above can also refer to the description of the two clamping blocks 1221, which will not be repeated here.
