Description

Technical Field

[0001] This utility model belongs to the field of cylinder wall cleaning technology for chemical materials, and specifically relates to an automated cylinder wall cleaning device for chemical engineering. Background Technology

[0002] Currently, chemical drums are the core containers for raw material storage and transfer. After use, they need to be thoroughly cleaned to achieve recycling and avoid contamination of subsequently stored materials by residual materials inside the drums. Therefore, chemical drum cleaning equipment has become a key piece of equipment in the post-processing stage of chemical production.

[0003] According to the prior art announcement number CN221602754U, a cleaning device for material barrels used in chemical engineering includes a support base plate and a fixed cylinder with a support cylinder fixedly connected to the top. A hydraulic rod for sliding is fixedly installed on the inner wall of the support cylinder. A mounting column for fixing is fixedly installed at the other end of the hydraulic rod. A mounting plate for fixing is fixedly installed on the surface of the mounting column. A mounting bracket for rotation is inserted into the bottom of the mounting plate.

[0004] Further search revealed that, according to prior art announcement number CN218191565U, a chemical safety cleaning device for chemical drums includes a cleaning tank and a chemical drum. Storage boxes are fixedly connected to both sides of the bottom of the inner wall of the cleaning tank. Slopes are fixedly connected to both sides of the inner wall of the cleaning tank, and a fixed frame is fixedly connected between the opposite sides of the two slopes. A cleaning mechanism is provided on the surface of the fixed frame. The cleaning mechanism includes a motor and a cleaning brush. One end of the motor's output shaft is fixedly connected to a first gear via a coupling. A fixed cylinder is rotatably connected to the top of the fixed frame.

[0005] The existing technology mentioned above has insufficient size adjustment capability of the cleaning components, which means that it can only carry out cleaning operations for chemical drums of a single or small range of sizes. When it is necessary to process drums of different sizes, it is necessary to frequently change the matching cleaning components, which not only reduces the cleaning efficiency, but also increases the complexity of equipment operation and additional tooling costs, making it difficult to meet the needs of batch cleaning of drums of multiple sizes in chemical production scenarios.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1) Motor I drives lead screw I to rotate, causing the entire mounting frame to move laterally within the mounting base, so that the clamping frame moves horizontally to directly above the chemical drum to be cleaned. Motor II drives two sets of lead screws II to rotate synchronously, causing the sliding seat II to move up and down along the groove on the side wall of the mounting frame, thereby driving the sliding frame to achieve vertical lifting and lowering. Motor V drives the bidirectional lead screw I to rotate through bevel gear meshing, pushing two sets of sliding seats III to move in opposite directions along the sliding frame. Through the connecting seat, the two sets of clamping frames open and close synchronously, realizing the adaptation and gripping of chemical drums of different sizes. The electric push rods at the bottom of the two sets of connecting seats extend and retract synchronously, further fine-tuning the vertical position of the clamping frame, so that it is accurately aligned with the two sides of the middle of the chemical drum to be cleaned and completes the clamping. It realizes multi-directional adjustment of horizontal movement, lifting, opening and closing, and can adapt to chemical drums of different sizes. With the fine adjustment of electric push rods, it can accurately align with the middle of the drum for clamping, improve the clamping stability, and provide a guarantee for efficient connection of subsequent cleaning processes.

[0018] 2) The mounting cylinder rotates synchronously with the rotating disk. Motor IV drives the bidirectional lead screw II to rotate. The two sets of sliding rings move in opposite directions along the bidirectional lead screw II. The other end of connecting rod I pushes the middle connecting rod II to swing around the hinge point of the mounting cylinder. The end of connecting rod II drives the sliding seat IV to slide along the bottom of the guide rail, so that the brush on the fixed plate I can accurately fit the inner wall of the chemical drum. The dovetail groove sliding plate, which is fixedly connected to the fixed plate I, slides along the fixed plate II with the guide rail, so that the brush on the fixed plate II and the dovetail groove sliding plate can be opened synchronously and fully fit the bottom of the chemical drum. This realizes the multi-directional adjustment of the brush, ensuring that the cleaning mechanism can adapt to the inner diameter of drums of different sizes, and meet the needs of batch cleaning of drums of various sizes in chemical production scenarios. The rotating brush, together with the cleaning agent of the spraying mechanism, realizes the coordinated operation of mechanical scrubbing and cleaning agent cleaning of the chemical drum wall, which greatly improves the cleaning efficiency and effect.

[0032] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-11 The technical solution of this utility model will be further described in detail below.

[0033] An automated cylinder wall cleaning device for chemical engineering includes a cleaning tank 1, a clamping mechanism 2, and a cleaning device 3. The cleaning tank 1 has a loading platform 101 at both ends, which is used to carry the chemical drum to be cleaned and the chemical drum that has been cleaned, respectively. The cleaning tank 1 has a drain outlet at one end of the loading platform 101 that carries the cleaned chemical drum. The drain outlet is connected to a wastewater collection tank. The clamping mechanism 2 is slidably installed on the top of the cleaning tank 1, and the cleaning device 3 is installed inside the cleaning tank 1.

[0034] As described above, the chemical drums to be cleaned are sent to the loading platform 101 at one end of the cleaning pool 1. The clamping mechanism 2 clamps the chemical drums to be cleaned and moves them to the top of the cleaning device 3 inside the cleaning pool 1. The cleaning device 3 is activated to automatically clean the walls of the chemical drums. The wastewater generated during the cleaning process flows automatically into the connected wastewater collection pool through the drain outlet at one end of the cleaning pool 1. After the cleaning is completed, the clamping mechanism 2 moves the cleaned chemical drums to the loading platform 101 at the other end, completing a single cleaning cycle, and waiting for subsequent use.

[0035] The clamping mechanism 2 includes a motor I 23, a lead screw I 24, a sliding base 25, a mounting bracket 26, a sliding frame 28, a sliding seat II 29, a motor II 211, a sliding seat III 212, a connecting seat 213, a fixed seat 216, a clamping frame 217, a motor III 219, and a motor V 220. Mounting seats 21 are provided on both sides of the cleaning tank 1. Each mounting seat 21 has a groove at its top and a sliding groove II 22 on its inner side. The sliding base 25 is slidably connected to the mounting seat 21 at both ends via the sliding groove II 22, and both ends of the sliding base 25 are located within the groove of the mounting seat 21. The lead screw I 24 is located at the bottom of the cleaning tank 1 and rotates with the loading platform 101. The connection is as follows: lead screw I 24 is threadedly connected to sliding base 25; motor I 23 is installed at one end of lead screw I 24; the output shaft of motor I 23 is fixedly connected to lead screw I; a waterproof shell is provided on the outside of motor I 23; an accordion-style protective cover is fitted onto lead screw I 24; mounting bracket 26 is fixedly connected to sliding base 25; lead screw II 27 is provided in the grooves on both sides of mounting bracket 26; lead screw II 27 is rotatably installed in the grooves on both sides of mounting bracket 26; the top of lead screw II 27 passes through the top of mounting bracket 26 and is provided with a synchronous pulley; motor II 211 is installed on the top of mounting bracket 26; the synchronous pulley on the output shaft of motor II 211 is connected to the synchronous pulley at the top of lead screw II 27 via a synchronous belt. The sliding frame 28 is threadedly connected to two sets of lead screws II 27 via sliding seats II 29 at both ends. The sliding seats II 29 are slidably installed in the grooves on both sides of the mounting frame 26. The sliding frame 28 is provided with a bidirectional lead screw I 210, and a bevel gear is provided in the middle of the bidirectional lead screw I 210. The motor V 220 is installed on one side of the sliding frame 28. The bevel gear on the output shaft of the motor V 220 meshes with the bevel gear in the middle of the bidirectional lead screw I 210. A protective shell is provided on the outside of the bevel gear in the middle of the bidirectional lead screw I 210. A protective shell is also provided on the outside of the motor V 220. The bottom of the sliding frame 28 is provided with a sliding groove III 221. There are two sets of sliding seats III 212, and both sets of sliding seats III 212 are connected to the bidirectional lead screw I 210. The sliding seat Ⅲ212 is slidably installed in the sliding frame 28. The bottom of the sliding frame 28 is provided with a sliding groove Ⅲ221. The sliding seat Ⅲ212 passes through the sliding groove Ⅲ221 and is fixedly connected to the connecting seat 213. The bottom of the connecting seat 213 is provided with an electric push rod 214. The electric push rod 214 is provided with telescopic rods Ⅰ215 on both sides. The telescopic ends of the electric push rod 214 and the telescopic rods Ⅰ215 are fixedly connected to a fixed seat 216. A clamping frame 217 is rotatably installed on the inner side of the fixed seat 216. A clamping block 218 is provided on one side of the clamping frame 217. The motor Ⅲ219 is installed on the outer side of the fixed seat 216. The output shaft of the motor Ⅲ219 passes through the fixed seat 216 and is fixedly connected to the clamping frame 217.

[0036] The motor Ⅲ219 is an angle stepper motor, and a protective cover is provided on the outside of the motor Ⅲ219;

[0037] As can be seen from the above structure: Motor I 23 drives lead screw I 24 to rotate, causing the entire mounting frame 26 to move laterally within the mounting base 21, so that the clamping frame 217 moves horizontally to directly above the chemical drum to be cleaned. Motor II 211 starts, driving the two sets of lead screws II 27 to rotate synchronously through synchronous belt transmission, causing the sliding seat II 29 to move up and down along the groove on the side wall of the mounting frame 26, thereby driving the sliding frame 28 to achieve vertical lifting and lowering, so that the clamping frame 217 moves to both sides of the chemical drum to be cleaned. Motor V 220 drives the bidirectional lead screw I 210 to rotate through bevel gear meshing, pushing the two sets of sliding seats III 212 to move in opposite directions along the sliding frame 28, and synchronously driving the two sets of clamping frames 217 through the connecting seat 213. The opening and closing mechanism adapts to gripping chemical drums of different sizes. The electric push rods 214 at the bottom of the two sets of connecting seats 213 extend and retract synchronously, further fine-tuning the vertical position of the gripping frame 217 so that it is precisely aligned with the two sides of the middle of the chemical drum to be cleaned and completes the gripping. The motor III 219 drives the gripping frame 217 to rotate 180° so that the opening of the chemical drum to be cleaned faces downward. Then the mounting frame 26 moves horizontally to the top of the cleaning device 3, and the gripping mechanism 2 fastens the chemical drum above the cleaning device 3. The cleaning device 3 starts and cleans the inner wall of the chemical drum to be cleaned. After cleaning, the gripping frame 217 rotates 180° again to reset, and the gripping mechanism transfers the cleaned chemical drum to the corresponding loading platform 101.

[0038] The cleaning device 3 includes a spraying mechanism 31 and a cleaning mechanism 32; both the spraying mechanism 31 and the cleaning mechanism 32 are installed in the cleaning tank 1.

[0039] The spraying mechanism 31 includes a rotating disk 3101, a connecting pipe 3103, and a reduction motor 3104. The rotating disk 3101 is rotatably installed in the middle of the cleaning tank 1. A connecting shaft 3102 is provided at the bottom of the rotating disk 3101. The rotating disk 3101 and the connecting shaft 3102 are hollow and interconnected. The bottom of the connecting shaft 3102 is connected to an external pipe through a sleeve. The external pipe is connected to a cleaning agent tank. The cleaning agent tank is existing technology, obtained through private customization or purchase, and is not within the scope of protection of this utility model. A synchronous pulley is provided on the connecting shaft 3102. The reduction motor 3104 is installed at one end of the cleaning tank 1. The synchronous pulley on the output shaft of the reduction motor 3104 is connected to the synchronous pulley on the connecting shaft 3102 through a synchronous belt. Several sets of connecting pipes 3103 are connected to the top of the rotating disk 3101. Spray nozzles are provided on the side walls and top of the connecting pipes 3103.

[0040] As described above, after the chemical drum to be cleaned is fastened onto the cleaning device 3, the cleaning agent in the cleaning agent tank is sent to the rotating disk 3101 through the external pipe and connecting shaft 3102, and then flows to each set of connecting pipes 3103. At the same time, the reduction motor 3104 drives the connecting shaft 3102 to rotate through the synchronous belt, which drives the rotating disk 3101 to rotate. The nozzles on the side wall and top of the connecting pipe 3103 spray the cleaning agent evenly onto the inner wall of the chemical drum to be cleaned as it rotates.

[0041] The cleaning mechanism 32 includes a mounting cylinder 3201, a motor IV 3202, a bidirectional lead screw II 3203, a sliding ring 3204, a connecting rod I 3205, a connecting rod II 3206, a guide rail 3208, a sliding seat IV 3211, a fixed plate II 3216, and a dovetail groove sliding plate 3217. The mounting cylinder 3201 is fixedly installed in the middle of the rotating disk 3101. A rotary connector is provided at the top of the mounting cylinder 3201. The bidirectional lead screw II 3203 is rotatably installed inside the mounting cylinder 3201. One end of the bidirectional lead screw II 3203 is fixedly connected to the output shaft of the motor IV 3202. The motor IV 3202 is installed inside the mounting cylinder 3201, and a partition is provided on one side of the motor IV 3202. A bellows-style protective cover is fitted onto the lead screw II 3203. Several sets of sliding grooves I 3207 are provided on the side wall of the mounting cylinder 3201. Both sets of sliding rings 3204 are threadedly connected to the bidirectional lead screw II 3203. Several connecting rods I 3205 are provided, and one end of the connecting rod I 3205 is hinged to the sliding ring 3204. The other end of the connecting rod I 3205 passes through the sliding groove I 3207 and is hinged to the middle of the connecting rod II 3206. One end of the connecting rod II 3206 is hinged to the mounting cylinder 3201, and the other end of the connecting rod II 3206 is hinged to the sliding seat IV 3211. The sliding seat IV 3211 is slidably installed in the bottom of the guide rail 3208. A fixing plate I 3213 is provided on one side of the guide rail 3208.

[0042] The brush 3214 is fixedly connected to the fixing plate I 3213 by bolts and nuts. The top of the mounting cylinder 3201 is provided with a fixing ring 3215. Several sets of fixing plates II 3216 are provided on the side wall of the fixing ring 3215. The fixing plate II 3216 is slidably connected to the dovetail groove sliding plate 3217. One end of the dovetail groove sliding plate 3217 is fixedly connected to the fixing plate I 3213. The fixing plate II 3216 and the dovetail groove sliding plate 3217 are both provided with brushes 3214 on one side. The fixing plate II 3216 is connected to the brush 3214 by bolts, and the dovetail groove sliding plate 3217 is connected to the brush 3214 by bolts.

[0043] The mounting cylinder 3201 has several sets of water outlets 3209 on its side wall. The water outlets 3209 are located on one side of the partition plate at the end of the motor IV 3202 and are used to discharge the cleaning agent that enters the mounting cylinder 3201 through the sliding groove I 3207.

[0044] As described above, the mounting cylinder 3201 rotates synchronously with the rotating disk 3101. The rotary connector enables dynamic electrical connection between the fixed circuit and the rotating component. When the mounting cylinder rotates synchronously with the rotating disk 3101, it prevents the wires of electrical components such as motor IV 3202 from becoming entangled, while continuously transmitting power to ensure the normal operation of motor IV 3202's drive and component adjustment functions, maintaining continuous and stable cleaning operations. Motor IV 3202 drives the bidirectional lead screw II 3203 to rotate, and the two sets of sliding rings 3204 translate in opposite directions along the bidirectional lead screw II 3203. One end of connecting rod I 3205 moves synchronously, and the other end of connecting rod I 3205 pushes the middle connecting rod II 3206 to swing around the hinge point of the mounting cylinder 3201. The end of connecting rod II 3206 drives the sliding seat IV 3211 to slide along the guide rail 3208, assisting the guide rail 3208 to move smoothly, so that the brush 3214 on the fixed plate I 3213 accurately fits the inner wall of the chemical drum.

[0045] When the fixed plate I 3213 moves with the guide rail 3208, the dovetail groove sliding plate 3217 slides along the fixed plate II 3216, so that the brush 3214 on the fixed plate II 3216 and the dovetail groove sliding plate 3217 unfold synchronously, fully adhering to the bottom of the chemical drum and fully covering different areas of the inner wall of the chemical drum. The rotating brush 3214, in conjunction with the cleaning agent of the spraying mechanism 31, realizes the coordinated operation of mechanical scrubbing and cleaning agent cleaning of the chemical drum wall.

[0046] During the cleaning process, a small amount of cleaning agent that seeps into the mounting cylinder 3201 through the sliding groove I 3207 is blocked by the baffle on the side of the motor IV 3202 and is eventually discharged through the outlet 3209 on the side wall of the mounting cylinder 3201, thus avoiding corrosion of the motor IV 3202 components and ensuring stable operation of the mechanism.
