Description

Technical Field

[0001] The present invention relates to the technical field of industrial environment cleaning, and particularly relates to a cleaning device with a self-cleaning function for industrial environment and a using method thereof. Background Art

[0002] The industrial environment refers to various factors and conditions involved in industrial production, including but not limited to factories, machinery and equipment, raw materials, energy, waste treatment, safety measures, etc. Cleaning and treating solid waste in the industrial environment is one of the important measures to prevent the deterioration of the industrial environment. Among industrial solid waste, waste metal paint cans with residual chlorine-containing paint inside belong to harmful solid waste. Long-term placement or arbitrary dumping and landfill will cause the residual chlorine-containing paint to pollute the industrial environment.

[0003] Chinese Patent CN202210021029.2 discloses a recycling and treatment process for waste paint cans, which includes the following steps:

[0004] (1) Residual pouring unit: Pour the residual paint liquid in the waste paint can, and at the same time manually clean the residual paint slag in the waste paint can; (2) Decomposition unit: According to the curing degree of the residual paint in the waste paint can, if it is not cured, first perform pyrolysis treatment and then shredding treatment. If it is cured, first perform shredding treatment and then pyrolysis treatment; (3) Crushing unit: Crush the decomposed waste paint can to obtain shredded waste paint can slag; (4) Magnetic separation unit: Transfer the shredded waste paint can slag after crushing treatment to a magnetic separator for magnetic separation treatment to recover iron substances; (5) Ball-making unit: Perform ball-making treatment on the recovered iron substances to make iron balls, which can effectively improve the comprehensive recycling and utilization of waste paint cans and reduce environmental pollution.

[0005] The following problems exist in the above patent and the prior art:

[0006] For the recycling and treatment of existing waste paint metal cans, most of them are decomposed and crushed, resulting in large energy consumption. Moreover, for the residual chlorine-containing paint inside the metal paint can, no targeted cleaning and elimination treatment is carried out, resulting in the inability to distinguish and treat the residual chlorine-containing paint inside the metal paint can from the metal paint can. The existing mixed crushing treatment of residual chlorine-containing paint and metal paint cans is easy to pollute the treatment device. Most of the residual chlorine-containing paint will caking and solidify at the bottom of the metal paint can, resulting in difficulties in targeted cleaning and elimination, which is not conducive to the efficient treatment of the caking of chlorine-containing paint and also hinders the recycling and utilization of metal paint cans.

[0032] Another object of the present invention is to provide a method for using a cleaning device with self-cleaning function for industrial environment, aiming at the deficiencies of the prior art, which includes the following steps:

[0033] Step 1, paint can clamping: Place the metal paint can to be processed inside the clamping ring plate, so that the metal paint can is fixed by the clamping ring plate.

[0034] Step 2, drill block material infiltration: Lower the drill bit into the metal paint can, and start the drill bit and make the paint remover water inside the softening cavity flow into the bottom surface of the paint block along with the drilling of the drill bit, so that there is paint remover water distributed between the paint block and the metal paint can.

[0035] Step 3, full vibration paint can removal: After the drill bit stops and resets, drive the first-stage elastic head and the second-stage elastic head to intermittently impact the center of the bottom surface and the side part of the metal paint can through the up and down movement of the central push plate at the bottom of the metal paint can, so that the paint remover water inside the metal paint can penetrates between the paint block and the metal paint can.

[0036] Step 4, inner wall cleaning: When the paint block detaches from the inside of the metal paint can, start the flipping drive source to drive the metal paint can clamped inside the clamping ring plate to flip and pour, so that the paint blocks that have detached from the inner wall of the metal paint can are poured into the inside of the liquid storage cavity. After pouring is completed, the metal paint can is reset, the synchronous sleeve is moved down and rotated, and the wall scraping knife and the sweeping and grinding roller at a rotating angle are used to perform rotational cleaning on the inner wall of the metal paint can.

[0037] Step 5, reset self-cleaning: After cleaning is completed, the synchronous sleeve and the reset member are reset, so that the dirt attached to the contact surface between the sweeping and grinding roller and the inner wall of the metal paint can is scraped off by the self-cleaning scraping knife, realizing self-cleaning.

[0038] The beneficial effects of the present invention:

[0039] (1) Manually place the paint cans to be processed inside the clamping ring plate. Then, drive the clamping ring plate to move by the clamping driving source, so that the clamping ring plate clamps and fixes the metal paint cans inside it. Next, start the cleaning driving part and the lifting driving source, make the drill bit rotate and move downward, and cooperate with the paint stripper flowing out from the softening outlet to the surface of the drill bit. Thus, the flowing paint stripper will flow between the bottom surface of the paint block and the inner bottom surface of the metal paint can along with the drilling of the drill bit, making it easier for the paint stripper to accumulate between the bottom surface of the paint block and the metal paint can, facilitating the softening of the connection surface between the two. Through the movement of the vibration source, under the alternating cooperation of the central vibration and the side vibration of the central push plate, the first-level elastic head, and the second-level elastic head, the paint stripper fully flows between the paint block and the metal paint can, quickly softening the adhesive contact surface between the paint block and the metal paint can, and then realizing the separation between the paint block and the metal paint can.

[0040] (2) By starting the downward movement driving part, the push rod at the bottom of the downward movement driving part drives the synchronous sleeve to move downward along the synchronous key on the surface of the transmission rod through the adjusting plate at its bottom, so that the synchronous sleeve covers the surface of the drill bit and the bottom surface of the synchronous sleeve is coplanar with the bottom surface of the drill bit. Thus, the bottom surface of the synchronous sleeve and the bottom surface of the bottom grinding plate are in contact with the inner bottom surface of the metal paint can. Then, start the cleaning driving part, and the cleaning driving part drives the transmission rod to rotate through the linkage component. During the rotation of the transmission rod, the synchronous sleeve connected to its surface through the synchronous key moves synchronously. Then, cooperate with the softening cavity to supply cleaning water to the inside of the softening outlet. Thus, inside the metal paint can, driven by the rotating synchronous sleeve, the wall scraper on the outer side of the synchronous sleeve and the bottom grinding plate first rotate and contact the inner wall of the metal paint can, thereby realizing the cleaning and scraping of the inner bottom surface and the inner wall of the metal paint can.

[0041] (3) Through the filter arc plate arranged between the bottom grinding plate and the buckle plate, during the rotation of the synchronous sleeve, the cleaning water inside the metal paint can is filtered. Combining with the design that the pore diameter of the filter holes on the surface of the filter arc plate is larger than the pore diameter of the filter holes on the surface of the flushing arc plate, the remaining small paint blocks inside the metal paint can are collected into the inside of the collection cavity, thereby reducing the paint blocks cleaned and scraped and piling up on the surfaces of the wall scraper and the sweeping and grinding roller during the rotation of the synchronous sleeve, and then realizing the self-cleaning of the wall scraper and the sweeping and grinding roller.

When the clamping ring plate 204 clamps the metal paint can, the top of the clamping ring plate 204 will preferentially clamp the metal paint can, and the large radius design at its bottom is more conducive to increasing the retention time of the hot air on the outer surface of the metal paint can. The height of the synchronous sleeve 303 is higher than the length of the drill bit 301, and the radius of the transmission rod 302 is larger than the radius of the drill bit 301, so as to facilitate the synchronous sleeve 303 to be sleeved and covered on the surface of the drill bit 301.

[0079] Among them, the lifting drive source 1031 and the cleaning drive member 1038 are preferably gear reduction motors, the flipping drive source 203 is preferably a servo motor, the downward movement drive member 1037 and the vibration source 2021 are preferably electric telescopic rods, the heating member 2023 is preferably a hot air blower, the clamping drive source 2024 is preferably an electric telescopic rod or a cylinder, the solenoid valve is preferably a stainless steel solenoid valve. The above devices are all powered by an external power supply and connected to a control panel composed of a PLC chip set externally (not shown), and their movements are controlled by the control panel.

[0080] Operation process:

[0081] When it is necessary to process a paint can containing paint lumps inside, manually place the paint can to be processed inside the clamping ring plate 204, so that the clamping driving source 2024 drives the clamping ring plate 204 to move, and the clamping ring plate 204 clamps and fixes the metal paint can inside it. Then start the cleaning driving member 1038 and the lifting driving source 1031, so that the drill bit 301 rotates and moves downward. Through the known internal height of the paint can, set the total stroke of the drill bit 301 from the top surface of the paint can to its bottom surface, so that the rotating and downward moving drill bit 301 can drill through the paint block. It should be noted that at this time, the bottom surface of the bottom grinding plate 306 is higher than the top surface of the metal paint can;

[0082] Then, in cooperation with the softening chamber 1036, the paint stripper is input into the interior of the liquid inlet chamber 10351 through the solenoid valve via the delivery pipe 10361. The paint stripper inside the liquid inlet chamber 10351 flows into the water delivery chamber 3022 inside the transmission rod 302 through the water inlet 3021, and the paint stripper flowing into the water delivery chamber 3022 flows out to the surface of the drill bit 301 through the softening outlet 3025. Thus, the flowing paint stripper will flow between the bottom surface of the paint block and the inner bottom surface of the metal paint can along with the drilling of the drill bit 301, making it easier for the paint stripper to accumulate between the bottom surface of the paint block and the metal paint can, facilitating the softening of the connection surface between the two;

[0083] After the drill bit 301 finishes drilling through, the drill bit 301 resets and lifts. At this time, the vibration source 2021 at the bottom of the metal paint can moves. Thus, during the lifting process of the output shaft of the vibration source 2021, the short connecting rod 206 will pull the cross - moving rod 2061 to move inward on the surface of the cross - slot 2026, causing the primary elastic head 2062 to impact the side wall of the metal paint can and the output shaft of the vibration source 2021 to drive the central push plate 205 to impact the center of the bottom surface of the metal paint can. During the falling process of the central push plate 205, the cross - moving rod 2061 and the primary elastic head 2062 reset, causing the central push plate 205 to pull the long connecting rod 207 to move, so that the secondary elastic head 2073 at the top of the long connecting rod 207 impacts the metal paint can. Thus, under the alternating combined vibration of the central vibration and the side vibration of the central push plate 205, the primary elastic head 2062 and the secondary elastic head 2073, the paint stripper fully flows between the paint block and the metal paint can, quickly softening the adhesive contact surface between the paint block and the metal paint can, and then realizing the separation between the paint block and the metal paint can;

[0086] As Figure 1-2As shown, both sides of the flip table 202 are provided with upright plates 201, and the inner side of the upright plates 201 is rotatably provided with side shafts 2011, and the upright plates 201 are rotatably connected to the side rotating seats 2012 fixed at the bottom of the flip table 202 through the side shafts 2011, and the outer side of the upright plates 201 is fixedly connected to a flip driving source 203, and the flip driving source 203 is rotatably connected to the side shafts 2011 through its output shaft;

[0087] A vibration source 2021 is disposed on the inner side of the side rotating seat 2012 , a hot air chamber 2022 is disposed on the side of the vibration source 2021 , a heating element 2023 is connected to the side of the hot air chamber 2022 , and clamping drive sources 2024 are symmetrically disposed on the left and right sides of the vibration source 2021 .

[0088] Among them, Figure 1-3 As shown, the vibration source 2021 passes through the flip table 202 and is movably connected to the central push plate 205 through its telescopic shaft, a transverse groove 2026 is provided on the surface of the flip table 202, a transverse rod 2061 is movably provided inside the transverse groove 2026, and a primary elastic head 2062 is provided on the inner side of the top of the transverse rod 2061;

[0089] The surface of the turning table 202 is provided with a rotating seat 2071, the top of the rotating seat 2071 is movably provided with a rocking rod 2072, the inner side of the top of the rocking rod 2072 is provided with a secondary elastic head 2073, the primary elastic head 2062 and the secondary elastic head 2073 are made of high temperature resistant rubber material, and the top surface of the central push plate 205 is provided with a buffer layer made of high temperature resistant rubber material;

[0090] The surface of the flip table 202 is symmetrically provided with moving grooves 2025, and the bottom of the clamping ring plate 204 is provided with an extension rod 2041, and the extension rod 2041 is slidably set inside the moving groove 2025. The clamping ring plate 204 is connected to the output shaft of the clamping drive source 2024 through the extension rod 2041 at its bottom.

[0091] Among them, Figure 1-3 As shown, the rotating seat 2071 and the transverse groove 2026 are symmetrically arranged with respect to the central axis of the central push plate 205, and an air outlet 20221 is arranged between the central push plate 205 and the movable groove 2025, and the air outlet 20221 penetrates the flip table 202 and is conductively connected with the hot air chamber 2022;

[0092] The rest of the structure is the same as that of Example 1.

[0093] Operation process:

[0094] In order to accelerate the separation speed of the paint block and the metal paint can, the heating element 2023 can be activated to deliver hot air into the interior of the hot air chamber 2022. The hot air delivered into the interior of the hot air chamber 2022 will be blown onto the surface of the metal paint can through the air outlet 20221. Combining with the design that the top radius of the clamping ring plate 204 is smaller than its bottom radius, the retention time of the hot air inside the clamping ring plate 204 is increased, so that the outer surface of the metal paint can is heated. Furthermore, in the paint stripping reaction of the external heating and the internal paint stripper, as well as the auxiliary vibration of the central push plate 205, the transverse moving rod 2061 and the secondary elastic head 2073, the stripping treatment efficiency of the paint block inside the metal paint can is specifically improved.

[0095] Through manual observation, when the paint block detaches from the interior of the metal paint can, the flipping drive source 203 is activated to drive the flipping and dumping of the metal paint can clamped inside the clamping ring plate 204, so that the paint blocks detached inside the metal paint can are poured into the interior of the liquid storage chamber 102. After the dumping is completed, the metal paint can is reset, so that the large-volume paint blocks inside the metal paint can are processed.

[0096] Then the downward movement driving member 1037 is activated, so that the push rod 10373 at the bottom of the downward movement driving member 1037 drives the synchronous sleeve 303 to move downward along the synchronous key 3024 on the surface of the transmission rod 302 through the adjusting plate 103731 at its bottom, so that the synchronous sleeve 303 covers the surface of the drill bit 301, and the bottom surface of the synchronous sleeve 303 and the bottom surface of the drill bit 301 are coplanar, so that the bottom surface of the synchronous sleeve 303 and the bottom surface of the bottom grinding plate 306 are in contact with the inner bottom surface of the metal paint can.

[0097] Then the cleaning driving member 1038 is activated, so that the cleaning driving member 1038 drives the transmission rod 302 to rotate through the linkage assembly 10381. During the rotation of the transmission rod 302, the synchronous sleeve 303 connected to its surface through the synchronous key 3024 moves synchronously. Coupled with the supply of cleaning water from the softening chamber 1036 to the interior of the softening outlet 3025, the interior of the metal paint can will be driven by the rotating synchronous sleeve 303, so that the wall scraper 30611 on the outer side of the synchronous sleeve 303 and the bottom grinding plate 306 first rotate and contact the inner wall of the metal paint can, so as to realize the preliminary cleaning and scraping of the inner bottom surface and the inner wall of the metal paint can.

[0098] After the wall scraper 30611 initially scrapes the metal paint can, the grinding roller 3062 on its side will contact the inner wall of the metal paint can. Under the action of the rotational friction force between the metal paint can and the grinding roller 3062, the grinding roller 3062 and the central rotating shaft 3063 inside it will rotate. The swing plate 30723 that rotates along with the top of the central rotating shaft 3063 will contact the column 3072 after rotating a certain angle. At this time, the reset part 307221 is compressed. It should be noted that the design of the reset part 307221 can reduce the vibration during cleaning. Thus, under the friction between the grinding roller 3062 and the metal paint can and the contact between the swing plate 30723 and the column 3072, after the central rotating shaft 3063 and the swing plate 30723 rotate a certain angle, the contact surface between the grinding roller 3062 and the inner wall of the metal paint can tends to be stable. Furthermore, when the grinding roller 3062 rotates, it realizes the grinding of the surface of the metal paint can, thereby reducing the scratches on the inner wall of the metal paint can caused by the wall scraper 30611. At the same time, it also further grinds and cleans the inner wall of the metal paint can, realizing the secondary cleaning of the chlorine-containing paint inside the metal paint can, which is convenient for the secondary utilization of the waste metal paint can;

[0099] The filtering arc plate 305 arranged between the bottom grinding plate 306 and the buckle plate 307 will filter the cleaning water inside the metal paint can during the rotation of the synchronous sleeve 303. Combining with the design that the aperture of the filtering holes on the surface of the filtering arc plate 305 is larger than that of the filtering holes on the surface of the flushing arc plate 308, the remaining small paint blocks inside the metal paint can are collected into the interior of the collection cavity 3081, thereby reducing the paint blocks scraped and cleaned and piling up on the surfaces of the wall scraper 30611 and the grinding roller 3062 during the rotation of the synchronous sleeve 303. Furthermore, it realizes the self-cleaning of the wall scraper 30611 and the grinding roller 3062 during cleaning;

[0100] By setting the shapes of the filtering arc plate 305 and the sealing arc plate 304, the cleaning water flowing through the collection cavity 3081 will be flung and flushed onto the surfaces of the wall scraper 30611 and the grinding roller 3062 under the action of the rotational centrifugal force, thereby increasing the cleaning lubrication degree of the wall scraper 30611 and the grinding roller 3062 and reducing the wear of the wall scraper 30611 and the grinding roller 3062. The rotary plate 3051 arranged on the side of the filtering arc plate 305, under the design of its radian, will guide the water flow passing through the surface of the filtering arc plate 305 through the rotary cavity 3052 and the rotary plate 3051, and part of it will be flushed onto the surface of the filtering arc plate 305, thereby realizing the self-cleaning of the filtering holes on the surface of the filtering arc plate 305 and further reducing the blockage of impurities accumulated on the surface of the filtering holes;

[0101] After the inner part of the metal paint can is cleaned by the wall scraping knife 30611 and the grinding roller 3062, the synchronous sleeve 303 is lifted, so that the frictional force restricting the rotation of the grinding roller 3062 disappears. Then, under the reset of the resetting member 307221, the grinding roller 3062 is driven to rotate back. During the reset rotation of the grinding roller 3062, the self-cleaning scraping knife 30612 scrapes and cleans the surface of the grinding roller 3062, thereby realizing the self-cleaning of the grinding roller 3062.

[0102] The remaining cleaning water inside the metal paint can is driven by the flipping driving source 203 to drive the clamping metal paint can inside the clamping ring plate 204 to flip and pour, so that the cleaning water inside the metal paint can is poured into the inside of the liquid storage cavity 102, and then the softening cleaning and recycling treatment of the metal paint can is completed, thereby reducing the pollution of the industrial environment.

[0103] Embodiment 3

[0104] As Figure 15 shown, this embodiment provides a method for using a cleaning device with a self-cleaning function for an industrial environment, which includes the following steps:

[0105] Step 1, paint can clamping: Place the metal paint can to be processed inside the clamping ring plate 204, so that the metal paint can is fixed by the clamping ring plate 204.

[0106] Step 2, drill block infiltration: Lower the drill bit 301 into the metal paint can, and start the drill bit 301 and make the paint remover water inside the softening cavity 1036 flow into the bottom surface of the paint block as the drill bit 301 drills, so that the paint remover water is distributed between the paint block and the metal paint can.

[0107] Step 3, full vibration to remove the can: After the drill bit 301 stops and resets, the up and down movement of the central push plate 205 at the bottom of the metal paint can drives the first-stage elastic head 2062 and the second-stage elastic head 2073 to intermittently impact the center and side of the bottom surface of the metal paint can, so that the paint remover water inside the metal paint can penetrates between the paint block and the metal paint can.

[0108] Step 4, clean the inner wall: When the paint block detaches from the inside of the metal paint can, start the flipping driving source 203 to drive the metal paint can clamped inside the clamping ring plate 204 to flip and pour, so that the paint blocks that have detached from the inner wall of the metal paint can are poured into the inside of the liquid storage cavity 102. After the pouring is completed, the metal paint can is reset, the synchronous sleeve 303 is lowered and rotated, and the wall scraping knife 30611 and the grinding roller 3062 at a rotating angle rotate and clean the inner wall of the metal paint can.

[0109] Step Five, Reset and Self-Cleaning: After the cleaning is completed, the synchronous sleeve 303 and the resetting member 307221 are reset, so that the dirt adhering to the contact surface between the grinding roller 3062 and the inner wall of the metal paint can is scraped off by the self-cleaning scraper 30612, realizing self-cleaning.
