Description

Technical Field

[0001] This invention relates to the field of parts cleaning technology, and more specifically to a cleaning device for automotive parts. Background Technology

[0002] Cleaning automotive parts is an important part of the automotive repair, maintenance, and manufacturing process.

[0003] Chinese Patent No. CN112108447B discloses a cleaning device for car parts. While the drive shaft rotates, a drive block on the side of the drive shaft slides against the bottom of a lifting block. The inner side of the groove on the bottom of the lifting block is corrugated. When the drive block and the lifting block slide relative to each other via ball bearings, the lifting block and the support block slide back and forth. Combined with a fourth spring connecting the lifting block and the support block, the lifting block continuously pushes the car parts located on the surface of the support block. A rotating cleaning brush can also flip the car parts, preventing them from remaining in constant contact with the support block and ensuring effective cleaning.

[0004] However, the aforementioned existing technology has the following drawbacks: For irregular automotive parts, their surfaces have some grooves and other structures. When the cleaning brush cleans the parts, the bristles cannot extend well into the inside of the groove structure, thus failing to effectively clean the groove structure on the surface of the parts, thereby reducing cleaning efficiency and cleaning power; in addition, the aforementioned existing technology only uses water to clean the parts and the cleaning method is singular, which cannot effectively clean the oil and rust on the surface of the parts, further reducing the cleaning power.

[0027] Example 1, as Figures 1-6 as well as Figure 8 As shown, the present invention provides a cleaning device for automotive parts, including a housing a, a cleaning mechanism, and a circulation mechanism.

[0028] The cleaning mechanism includes a housing b9, a hollow column 14, a hollow screw 6, a plate a8, a plate b21, a disc 10, an aeration assembly, and a motor 7. The housing b9 is rotatably mounted inside the housing a1. The motor 7 is mounted on the housing a1 through a housing and is connected to the housing b9 via a transmission connection. Multiple circumferentially distributed toothed grooves 902 are formed on the surface of the housing b9. A gear 5 is connected to the output end of the motor 7. An opening is formed on the housing a1. The gear 5 passes through the opening and meshes with the toothed grooves 902. The motor 7 drives the gear 5 at its output end to rotate, and the gear 5 drives the housing b9 to rotate via the toothed grooves 902. The rotating mechanism can spin-dry the cleaned parts; the hollow column 14 is located inside the box b9; the disc 10 is located on the hollow column 14; multiple plates a8 and b21 are provided and circumferentially distributed on the disc 10, and both plates a8 and b21 are connected to the hollow column 14; an opening a is provided on the outer circumferential surface of the hollow column between two adjacent sets of plates a (8); an opening b is provided on the outer circumferential surface of the hollow column between two adjacent sets of plates b (21); a filter screen a (15) is provided on the inner wall of the opening a and the opening b; a filter screen a (15) is provided on the disc (10) between two adjacent sets of plates a (8). Opening c; the inner wall of opening c is provided with filter screen b (13), filter screen a15 and filter screen b13 act as a barrier to prevent the components from being washed away by the flowing liquid, and the diamond particles can pass through the holes on filter screen a15 and filter screen b13; plate a8 and plate b21 correspond one to one; the space between two adjacent sets of plates a8 and two adjacent sets of plates b21 forms a flow channel for liquid flow; the hollow column 14 is provided with a baffle 20 inside, and the setting of the baffle 20 makes the liquid entering the hollow column 14 only flow through the filter screen a15 on the side and into the space between the adjacent plates a8. The system enables liquid diversion; the aeration assembly is located on the housing b9 to aerate the space between two adjacent plates a8; the hollow screw 6 is located at the top of the hollow column 14 and communicates with it; the inner wall of the housing b9 and the surface of the plate a8 are provided with an anti-corrosion rubber layer to prevent deformation of the parts when they collide with it; a sealing groove 901 is provided at the top of the housing b9; a sealing cover 2 is threaded onto the hollow screw 6; the bottom of the sealing cover 2 is provided with a sealing ring that is inserted into the sealing groove 901, and the sealing cover 2 can seal the housing b9 to prevent the flowing liquid from splashing out.

[0029] In this embodiment, the parts to be cleaned are placed on the disc 10 inside the housing b9. When the cleaning agent enters the hollow column 14, the liquid can only pass through the side filter a15 and enter the space between the two adjacent plates a8 under the blocking action of the baffle 20, realizing the diversion function of the cleaning agent. The cleaning agent entering the space between the two adjacent plates a8 will rinse the parts and clean the oil stains on the surface of the parts. At the same time, the diamond particles in the cleaning agent will impact and rub the surface of the parts under the action of the flow of the cleaning agent. At the same time, the diamond particles will also enter the grooves on the surface of the parts under the action of the cleaning liquid, polishing and cleaning the rust in the grooves on the surface of irregular parts. The cleaned rust will be washed away by the cleaning agent. The cleaning agent between the adjacent plates a8 will carry the diamond particles through the filter b13 and into the space between the two adjacent plates b21, and finally through the filter a15 at the bottom and flow into the hollow column 14.

[0030] The circulation mechanism includes a water tank 3, a pump body 4, pipe a22, and pipe b23. The water tank 3 contains a mixture of cleaning agent and abrasive particles. The cleaning agent includes, but is not limited to, water-based cleaning agents, which can be selected based on the oil stains on the surface of the parts. Water-based cleaning agents can be recycled 5-20 times. The mixing ratio of the cleaning agent and abrasive particles can be determined through a limited number of experiments. The pump body 4 is a slurry pump, specifically designed for high-concentration abrasive slurries. The flow-through components are made of ultra-hard materials. It is suitable for applications with high abrasive concentrations and large particles (e.g., particle size > 100μm). The pump body 4 is mounted on and connected to the water tank 3. The pump body 4 is connected to the hollow screw 6 via pipe a22; pipe a22 is rotatably connected to the hollow screw 6; the water tank 3 is connected to the hollow column 14 via pipe c26 and pipe b23; pipe c26 and pipe b23 are connected; pipe b23 is rotatably connected to the hollow column 14; the pump body 4 has a pipe d25 at its pumping end; pipe d25 and pipe c26 are both connected to the clean water area and the solvent area, and the part of pipe d25 located outside the water tank 3 is connected to pipe e27; the water tank 3 has a baffle 24 inside; the baffle 24 divides the inside of the water tank 3 into a clean water area and a solvent area; the water tank 3 has an inlet pipe and an outlet pipe located at the clean water area and the solvent area respectively.

[0031] In this embodiment, both pipes C26 and D25 are tee pipes. The branch pipes on both pipes C26 and D25, used to connect the clean water area and the solvent area, are equipped with solenoid valves. When cleaning the components is required, the solenoid valves on the branch pipes of pipes D25 and C26 connecting to the solvent area are opened. The pump body 4 draws the solvent mixture of cleaning agent and diamond particles into pipe A22, then into the hollow screw 6, and finally into the inner side of the hollow column 14. The mixture then flows back to the solvent area through pipe C26. When cleaning residual cleaning agent and diamond particles from the components is required, the solenoid valves on the branch pipes of pipes D25 and C26 connecting to the solvent area are closed. Then, the solenoid valves on the branch pipes of pipes D25 and C26 connecting to the clean water area are opened. The pump body 4 delivers clean water to the space between the two adjacent plates A8 to rinse the components, thus cleaning the residual cleaning agent and diamond particles from the surface of the components.

[0032] It should be noted that a solenoid valve is installed on pipe e27. After the dirt and rust on the surface of the parts are cleaned, the solenoid valve on the branch pipe connecting to the solvent area on pipe d25 is closed, while the solenoid valve on the branch pipe connecting to the solvent area on pipe c26 remains open. The solenoid valve on pipe e27 is opened, and the pump body 4 allows outside air to enter the inside of the hollow column 14, thereby allowing all the cleaning agent and diamond particles remaining inside the box b9, hollow column 14, pipe b23 and pipe c26 to be discharged into the solvent area inside the water tank 3.

[0033] It is worth noting that when the mixed solvent of cleaning agent and diamond particles is injected into the solvent zone inside water tank 3, pump 4 is turned on to deliver the mixed solvent to tank b9. This is because when the mixed solvent is first injected into the solvent zone, the diamond particles will not settle, and the mixed solvent is still in a uniformly mixed state. As the mixed solvent circulates back to the solvent zone, it can continuously tumble, thus preventing the diamond particles from settling. When the mixed solvent is reused, the diamond particles in the mixed solvent will settle. However, after one circulation under the action of pump 4, the mixed solvent will start to tumble (because the mixed solvent circulating back to the solvent zone will continuously flow into the solvent zone from below water tank 3 through pipe c26), causing the originally settled diamond particles to mix evenly with the cleaning agent again.

[0034] Example 2, as Figure 3 and Figure 7As shown, this invention proposes a cleaning device for automotive parts. Compared to Embodiment 1, this embodiment further details the structure of the aeration assembly. The disc 10 has multiple parallel inclined holes 1301 inside. The aeration assembly includes an air pump 11, an annular pipe 12, a straight pipe 16, a horizontal pipe 17, an inclined pipe 18, and an aeration valve 19. The air pump 11 and the annular pipe 12 are both mounted on the housing b9, and the air pump 11 is connected to the annular pipe 12. Multiple straight pipes 16 are arranged circumferentially on the annular pipe 12. The straight pipe 16 extends between two adjacent sets of plates b21 and is connected to the annular pipe 12. The straight pipe 16 is connected to the horizontal pipe 17. Multiple inclined pipes 18 are provided and connected to the inside of the inclined hole 1301. The inclined pipe 18 is connected to the horizontal pipe 17. The aeration valve 19 is located at the top of the inclined pipe 18. The inclined pipe 18 is inclined towards the hollow column 14, so that the gas sprayed by the aeration valve 19 is directed towards the hollow column 14. This can blow the parts towards the hollow column 14 and prevent the parts from accumulating together under the action of liquid flushing, thus affecting the cleaning effect.

[0035] In this embodiment, when the cleaning fluid is used in conjunction with diamond abrasive to clean the parts, an air pump 11 delivers outside air to the inside of the annular pipe 12, then into the straight pipe 16, and then into the inclined pipe 18. Finally, the air is sprayed out through the aeration valve 19. The sprayed gas causes the parts to rotate continuously, which facilitates the cleaning agent and diamond abrasive to thoroughly clean and remove rust from the parts. Since the gas sprayed out by the aeration valve 19 can blow the parts toward the hollow column 14, the parts and the flowing mixed solvent will move in opposite directions, thereby increasing the scouring force of the mixed solvent on the parts and thus improving the cleaning effect of the parts.

[0036] It should be noted that aeration is carried out during the cleaning of parts. When the bubbles generated by aeration burst, the resulting micro-jet can peel off the contaminants attached to the surface of the parts (similar to the cavitation effect); the oxygen in the gas can promote the oxidative decomposition of organic contaminants (such as grease) (especially when used in conjunction with alkaline cleaning agents); aeration can enhance liquid flow, prevent the sedimentation of diamond particles, and improve the uniformity of cleaning; the aeration volume should be controlled at 0.5~1.5 m³ / h·m².

[0037] It is worth noting that an air inlet is provided at the bottom of the housing a1 to facilitate the entry of outside air and ensure that the air pump 11 can work normally.

[0038] In summary, when using this invention, first rotate the sealing cover 2 to move it upward and open the box b9, place the parts to be cleaned on the disc 10 between the two adjacent plates a8, and then move the sealing cover 2 downward to reset and seal the box b9.

[0039] First, open the solenoid valves on the branch pipes connecting to the solvent area on pipes d25 and c26. Then, inject the mixed solvent of cleaning agent and diamond particles into the solvent area of ​​water tank 3 through the inlet pipe. At the same time, turn on pump 4 to draw the mixed solvent into pipe d25, then into pipe a22, and then into hollow screw 6. Finally, it enters the inside of hollow column 14, passes through filter screen a15 above hollow column 14, flows into the area between adjacent plates a8, then passes through filter screen b13 on disc 10, enters the area between adjacent plates b21, and finally passes through filter screen below hollow column 14. A15 returns to the inside of the hollow column 14, and then flows back to the solvent area through pipes B23 and C26, completing the circulation function of the mixed solvent. When the mixed solvent flows between adjacent plates A8, it washes the components. The cleaning agent cleans the oil stains on the surface of the components, and simultaneously, the diamond particles in the cleaning agent impact and rub the surface of the components under the action of the flowing cleaning agent. At the same time, the diamond particles are also carried by the cleaning liquid into the grooves on the surface of the components, polishing and cleaning the rust in the grooves of irregular component surfaces. The removed rust is then washed away by the cleaning agent. The air is flushed away and returned to the solvent zone along with the mixed solvent. While the parts are being cleaned, the air pump 11 is turned on to deliver outside air to the inside of the annular pipe 12, then into the straight pipe 16, and then into the inclined pipe 18. Finally, it is sprayed out through the aeration valve 19. The sprayed gas can make the parts continuously rotate, which facilitates the cleaning agent and diamond particles to thoroughly clean and remove rust from the parts. Since the gas sprayed out by the aeration valve 19 can blow the parts towards the hollow column 14, the parts and the flowing mixed solvent will move in opposite directions, thereby increasing the flushing force of the mixed solvent on the parts and thus improving the cleaning efficiency of the parts. In addition, the micro-jet generated when the bubbles generated by aeration burst can peel off the contaminants attached to the surface of the parts (similar to the cavitation effect). The oxygen in the gas can promote the oxidative decomposition of organic contaminants (such as grease) (especially when combined with alkaline cleaning agents). At the same time, aeration can enhance the liquid flow, prevent the diamond particles from settling, and improve the uniformity of the parts cleaning. Thus, the combination of aeration and mixed solvent rinsing can achieve efficient cleaning of irregular parts and reduce the cleaning difficulty of irregular parts.

[0040] After the parts cleaning is completed, close the solenoid valve on the branch pipe connecting to the solvent area on pipe d25, keep the solenoid valve on the branch pipe connecting to the solvent area on pipe c26 open, and open the solenoid valve on pipe e27. Use pump body 4 to allow outside air to enter the inside of hollow column 14, thereby draining all the residual cleaning agent and diamond particles inside the box b9, hollow column 14, pipe b23, and pipe c26 into the solvent area inside water tank 3. Then close the solenoid valve on pipe e27 and the solenoid valve on the branch pipe connecting to the solvent area on pipe c26, and open the solenoid valve on the branch pipe connecting to the solvent area on pipe d25 and pipe c26. Turn on the solenoid valve on the branch pipe of the clear water zone; turn on pump body 4 again to deliver clear water to the area between the two adjacent plates a8 to rinse the cleaned parts, washing away the residual cleaning agent and diamond particles on the surface of the parts and returning them to the clear water zone through pipe c26 (the clear water in the clear water zone needs to be replaced after being reused 2-3 times). Keep the aeration components working during the rinsing process to ensure thorough rinsing. After rinsing, turn off the solenoid valve on the branch pipe connecting to the clear water zone on the opening pipe d25, and turn on motor 7. Motor 7 drives the gear 5 at its output end to rotate. Gear 5, in conjunction with tooth groove 902, drives housing b9 to rotate. Housing b9 drives hollow column 14, plate a8, plate b21, and disc 10 to rotate, which in turn drives the rinsed parts to rotate. Centrifugal force is used to spin dry the residual water on the surface of the parts (the aeration components continue to work during the spin-drying process, and the airflow generated by the aeration components can accelerate the drying of the parts), which facilitates the rapid drying of the parts. After the spin-drying is completed, the solenoid valve on pipe e27 is opened again, and the pump body 4 is used to make all the residual water in housing b9, hollow column 14, pipe b23, and pipe c26 flow back to the clean water area. Then the solenoid valve on the branch pipe on pipe c26 that connects to the clean water area is closed.

[0041] Finally, open the sealing cover 2 and remove the cleaned parts from the box b9.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
