Description

Technical Field

[0001] This invention relates to the technical field of cleaning and treatment of fasteners for rail transit, and particularly to an integrated device and method for degreasing, cleaning, dehydrating and drying screws used in rail transit. Background Technology

[0002] Screws and other fasteners used in the assembly of rail transit equipment may have rust-preventing oil stains, dust and other impurities adhering to their surfaces during the manufacturing or storage process. They need to be degreased, cleaned and dried before installation and use.

[0003] Traditional processing methods often involve manual rinsing or separate equipment to complete multiple processes such as degreasing, rinsing, and drying. This requires multiple transfers of the workpiece, resulting in low efficiency and high labor costs, making it difficult to meet the cleaning needs of large quantities of screws in the rail transit sector.

[0004] Meanwhile, conventional conveyor belt cleaning equipment is prone to leaving oil and cleaning foam residue on the conveyor belt surface, which can easily cause secondary pollution of workpieces with long-term use. In addition, when small parts such as screws are stacked for cleaning, blind spots are easily created, resulting in incomplete degreasing and rinsing, uneven drying effect, and affecting subsequent assembly and use.

[0005] Therefore, it is necessary to provide an integrated device and method for degreasing, cleaning, dehydrating and drying screws used in rail transit, in order to solve the problems mentioned in the background art. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies, such as dispersed processes, low cleaning efficiency, and easy secondary pollution, and to provide an integrated device for degreasing, cleaning, dehydrating and drying screws for rail transit that integrates feeding, degreasing, cleaning, drying and storage, and can self-clean the conveyor belt.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an integrated device and method for degreasing, cleaning, dehydrating and drying screws for rail transit, comprising a feeding component, a degreasing component, a cleaning component, a drying component and a storage component;

[0008] The storage component includes a base plate, and the feeding component, degreasing component, cleaning component, and drying component are all mounted on the base plate;

[0009] The feeding assembly includes a main support frame and a feeding bin fixedly installed inside the main support frame;

[0010] The degreasing assembly includes a water tank, a foaming machine, a spray gun, and a vibration transmission mechanism, all fixedly installed on the main support frame.

[0011] The cleaning assembly includes a cleaning chamber and a high-pressure water gun located inside the cleaning chamber;

[0012] The drying assembly includes a support sleeve and a drying cylinder that is tumbled within the support sleeve.

[0013] As a preferred embodiment of the present invention, the vibration transmission mechanism includes a second support frame fixedly installed at the bottom of the main support frame, and an arc-shaped driven wheel and a first driving wheel are rotatably installed on the second support frame;

[0014] The arc-shaped driven wheel and the first driving wheel are fitted with a first conveyor belt. A vibrator is fixedly installed on the second support frame. The output end of the vibrator is provided with a telescopic rod. A spring is fitted on the outside of the telescopic rod. The telescopic rod is in contact with the bottom of the first conveyor belt.

[0015] The second support frame is equipped with a transfer bucket.

[0016] In a preferred embodiment of the present invention, the water tank, the foaming machine, and the spray gun are all fixedly installed on the main support frame, the foaming machine is equipped with a nozzle, and the water tank and the foaming machine are connected by a water pipe.

[0017] As a preferred embodiment of the present invention, the cleaning chamber is fixedly installed on the base plate via raised legs, and a third support frame is provided inside the cleaning chamber. Two sets of high-pressure water guns are fixedly installed on the third support frame, and a partition is fixedly installed on the third support frame.

[0018] The third support frame is rotatably mounted with a second driving wheel and a second driven wheel, and a second conveyor belt is fitted over the second driving wheel and the second driven wheel.

[0019] As a preferred embodiment of the present invention, a scrubbing machine is fixedly installed at the bottom of the third support frame, and a scrubbing chamber is fixedly installed at the bottom of the scrubbing machine. The scrubbing chamber can wrap around the outer wall of the second conveyor belt, and a cleaning brush cylinder is rotatably connected inside the scrubbing chamber.

[0020] As a preferred embodiment of the present invention, the drying assembly further includes a diagonal support frame, on which a motor is fixedly installed. The output end of the motor is provided with a drum, and the outer wall of the drying drum is provided with a rotating ring, which can be driven to rotate by the drum.

[0021] As a preferred embodiment of the present invention, the bottom of the feeding hopper is rectangular, so that the screws are arranged in a horizontal position when they fall from the feeding hopper onto the first conveyor belt.

[0022] As a preferred embodiment of the present invention, the storage component further includes a storage box, which is fixedly installed on the base plate.

[0023] This invention also provides a method for an integrated device for degreasing, cleaning, dehydrating, and drying screws used in rail transit, employing the integrated device for degreasing, cleaning, dehydrating, and drying screws used in rail transit as described above, including the following:

[0024] During loading, screws are placed into the loading bin, and the screws fall from the loading bin onto the first conveyor belt and are arranged horizontally.

[0025] During degreasing, the spray gun first blows away impurities from the screw surface, the foaming machine agitates the cleaning solution into foam and sprays it onto the screw surface through the nozzle, and the vibrator drives the first conveyor belt to vibrate, causing the screw to vibrate in the foam to remove oil.

[0026] During cleaning, the screws fall into the second conveyor belt via a transfer bucket. Two sets of high-pressure water guns sequentially rinse the foam off the surface of the screws. A partition moves the screws to flip over for thorough rinsing. The cleaning brushes in the scrubbing chamber simultaneously clean the second conveyor belt.

[0027] During the drying process, the cleaned screws enter the drying drum, which rotates and introduces high-temperature gas to dehydrate and dry the screws.

[0028] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: It adopts an integrated layout, integrating feeding, degreasing, cleaning, drying, and storage functions onto a single base plate. This eliminates the need for multiple machines to transfer workpieces, enabling fully automated continuous operation and significantly improving the batch cleaning efficiency of rail transit screws, while reducing labor costs. The foam vibration degreasing structure, with an arc-shaped conveyor belt and high-frequency vibration, ensures screws fully contact dense cleaning foam, resulting in more uniform and thorough degreasing. Combined with a pre-blowing dust removal process, it avoids large particles affecting the cleaning effect and improves degreasing quality. The invention features a tumbling rinsing and conveyor belt self-cleaning structure, with two sets of water guns and partitions achieving comprehensive double-sided rinsing of screws. The brushing chamber simultaneously cleans the surface and crevices of the conveyor belt, preventing secondary contamination of workpieces due to residual oil and foam. It eliminates the need to stop the machine to clean the conveyor belt, extending continuous operation time. The rotary hot air drying structure, with the drying drum rotating and causing the screws to tumble, combined with continuous high-temperature gas, achieves all-around uniform dehydration and drying of the screws, resulting in high drying efficiency and excellent effect, suitable for the batch drying needs of small screw parts.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0045] Please see Figure 1-7The present invention provides a technical solution: an integrated device and method for degreasing, cleaning, dehydrating and drying screws for rail transit, comprising a feeding component 2, a degreasing component 1, a cleaning component 3, a drying component 4 and a storage component 5. The storage component 5 includes a base plate 502. The feeding component 2, the degreasing component 1, the cleaning component 3 and the drying component 4 are all mounted on the base plate 502. The feeding component 2 includes a main support frame 202 and a feeding bin 201 fixedly installed in the main support frame 202. The degreasing component 1 includes a water tank 110, a foaming machine 113, a spray gun 111 and a vibration transmission mechanism fixedly installed on the main support frame 202. The cleaning component 3 includes a cleaning chamber 301 and a high-pressure water gun 303 located in the cleaning chamber 301. The drying component 4 includes a support sleeve 410 and a drying cylinder 401 rotatably connected in the support sleeve 410.

[0046] Specifically, the feeding component 2, degreasing component 1, cleaning component 3, drying component 4, and storage component 5 are arranged sequentially on the base plate 502 along the processing steps. Each component shares the same base plate 502 to form an integrated structure, integrating screw feeding, foam degreasing, high-pressure rinsing, rotary drying, and storage into a single unit for continuous operation, eliminating the need for manual transfer between independent equipment. The degreasing component 1 uses the main support frame 202 as the installation base, on which the water tank 110, foaming machine 113, and spray gun 111 are fixedly installed, and a built-in vibration transmission mechanism is used to apply high-frequency vibration to promote degreasing while conveying screws. The cleaning component 3 uses the cleaning chamber 301 as the processing cavity, and a high-pressure water gun 303 is installed inside to perform high-pressure rinsing on the degreased screws. The drying component 4 uses the support sleeve 410 to support and limit the rotation center of the drying cylinder 401, so that the screws rotate and are heated and dehydrated inside the drying cylinder 401.

[0047] Based on the above embodiments, the present invention realizes an integrated continuous operation of screw degreasing, cleaning, dehydration and drying and storage, eliminating the need for manual transfer between independent equipment, which improves processing efficiency and reduces the risk of cross-contamination and labor costs.

[0048] The vibration transmission mechanism includes a second support frame 120 fixedly installed at the bottom of the main support frame 202. An arc-shaped driven wheel 121 and a first driving wheel 123 are rotatably installed on the second support frame 120. A first conveyor belt 124 is sleeved on the arc-shaped driven wheel 121 and the first driving wheel 123. A vibrator 140 is fixedly installed on the second support frame 120. A telescopic rod 141 is provided at the output end of the vibrator 140. A spring 142 is sleeved on the outside of the telescopic rod 141. The telescopic rod 141 contacts the bottom of the first conveyor belt 124. A transfer bucket 130 is provided on the second support frame 120.

[0049] Specifically, the first conveyor belt 124 is supported by the arc-shaped driven wheel 121 and the first driving wheel 123. Its material-bearing surface is arc-shaped, which is adapted to the shape of the horizontally arranged screws. The vibrator 140 is fixedly installed on the second support frame 120. Its output end is connected to the bottom of the first conveyor belt 124 via the telescopic rod 141 and the spring 142 sleeved on the telescopic rod 141. The spring 142 provides rebound buffer and pre-tension while transmitting vibration. The inner side of the second support frame 120 is also provided with a transfer bucket 130, which is used to receive the degreased screws and transfer them to the cleaning assembly 3.

[0050] Based on the above embodiments, the arc-shaped material-bearing surface ensures that the horizontally arranged screws are stable and do not roll off during conveying. The vibrator 140 transmits high-frequency vibration to the first conveyor belt 124 through the elasticity of the spring 142, causing the screws to vibrate continuously in the foam, further promoting the penetration of the degreasing cleaning agent into the thread gaps on the screw surface and improving the degreasing effect.

[0051] The water tank 110, the foam generator 113, and the spray gun 111 are all fixedly installed on the main support frame 202. The foam generator 113 is equipped with a nozzle 114. The water tank 110 and the foam generator 113 are connected by a water pipe 112.

[0052] Specifically, the water tank 110 supplies degreasing cleaning liquid to the foaming machine 113 via the water pipe 112. The foaming machine 113 foams the cleaning liquid and then sprays dense cleaning foam onto the screws on the first conveyor belt 124 through the nozzle 114. The spray gun 111 is fixedly installed on the main support frame 202, and its rear is connected to an external compressor, which can spray high-pressure gas onto the screws.

[0053] Based on the above embodiments, the spray gun 111 first blows away the floating dust and loose impurities on the surface of the screw to create a clean base for subsequent foam degreasing. The foaming machine 113 draws liquid, foams, and sprays dense foam through the nozzle 114 onto the arc-shaped first conveyor belt 124, so that the screw is fully immersed in the foam, achieving a natural connection between pre-removal of impurities and foam degreasing.

[0054] The cleaning chamber 301 is fixedly installed on the base plate 502 via the lifting leg 330. The cleaning chamber 301 is provided with a third support frame 302. Two sets of high-pressure water guns 303 are fixedly installed on the third support frame 302. A partition 304 is fixedly installed on the third support frame 302. A second driving wheel 310 and a second driven wheel 312 are rotatably installed on the third support frame 302. A second conveyor belt 311 is provided around the second driving wheel 310 and the second driven wheel 312.

[0055] Specifically, the cleaning chamber 301 is raised above the base plate 502 via the lifting leg 330. Inside, two sets of high-pressure water guns 303 are arranged sequentially along the conveying direction on the third support frame 302. A partition 304 is provided between the two sets of high-pressure water guns 303. The second driving wheel 310 and the second driven wheel 312 support the hollow design of the second conveyor belt 311, so that the foam after rinsing drips from the gaps.

[0056] Based on the above embodiments, after the screw falls into the second conveyor belt 311 through the transfer bucket 130, the surface foam is first washed off by the front high-pressure water gun 303, and then the position is changed by the partition 304. Under the rear high-pressure water gun 303, the back and blind areas are thoroughly rinsed. The perforated second conveyor belt 311 allows the rinsing foam to drip off in time, avoiding liquid accumulation and ensuring thorough cleaning.

[0057] A brush washing machine 321 is fixedly installed at the bottom of the third support frame 302. A brush washing chamber 320 is fixedly installed at the bottom of the brush washing machine 321. The brush washing chamber 320 can wrap around the outer wall of the second conveyor belt 311. A cleaning brush cylinder 322 is rotatably connected inside the brush washing chamber 320.

[0058] Specifically, the brushing machine 321 is fixedly installed at the bottom of the third support frame 302. The cleaning brush cylinder 322 driven by it rotates at high speed. The brushing chamber 320 wraps around and clamps the outer wall of the second conveyor belt 311. Atmospheric pressure water is introduced into the chamber to rinse the second conveyor belt 311 on the return trip.

[0059] Based on the above embodiments, since foam has a certain adhesion and is easy to remain in the hollow gaps of the second conveyor belt 311, when the second conveyor belt 311 is conveyed back with the second drive wheel 310, it passes through the brushing chamber 320. The high-speed rotating cleaning brush 322 brushes the gaps and surfaces simultaneously and is combined with normal pressure water rinsing to remove foam residues attached to the upper and lower surfaces, avoids contamination of subsequent batches of screws, and ensures that the conveyor belt remains clean.

[0060] The drying assembly 4 also includes a diagonal support frame 420, on which a motor 421 is fixedly installed. The output end of the motor 421 is provided with a drum 422. The outer wall of the drying cylinder 401 is provided with a rotating ring 402, which can be driven to rotate by the drum 422.

[0061] Specifically, the motor 421 is fixedly installed on the inclined support frame 420, and its output end is driven by the roller 422 and the rotating ring 402 on the outer wall of the drying cylinder 401; the support sleeve 410 supports and limits the rotation center of the drying cylinder 401, and a continuous high-temperature gas is introduced into the drying cylinder 401.

[0062] Based on the above embodiments, the motor 421 drives the drying drum 401 to rotate via the drum 422 and the rotating ring 402, causing the screws inside the drum to tumble and be heated evenly. Combined with continuous high-temperature gas, the dehydration and drying are completed quickly. The dried screws fall out of the drying drum 401 and enter the storage component 5, realizing a closed loop of the post-cleaning process.

[0063] The bottom of the feeding bin 201 is rectangular, so that the screws are arranged horizontally when they fall from the feeding bin 201 onto the first conveyor belt 124.

[0064] Specifically, the bottom of the feeding hopper 201 has a rectangular opening, and the screws fall horizontally onto the first conveyor belt 124 as they fall from inside the hopper.

[0065] Based on the above embodiments, the rectangular bottom keeps the screws horizontally aligned during the falling process, which is compatible with the surface shape of the arc-shaped first conveyor belt 124, avoiding vertical jamming or messy posture of the screws, ensuring neat feeding, and facilitating stable operation of subsequent degreasing processes.

[0066] The storage component 5 also includes a storage box 501, which is fixedly installed on the base plate 502.

[0067] Specifically, the storage box 501 is fixedly installed on the base plate 502, located downstream of the discharge of the drying component 4, and is used to receive the screws after drying is completed.

[0068] Based on the above embodiments, the storage box 501 collects the dried and clean screws, enabling the whole machine to have a complete integrated "feeding-processing-discharging" capability, which facilitates unified recycling and turnover.

[0069] This embodiment also provides a method for an integrated device for degreasing, cleaning, dehydrating, and drying screws used in rail transit. The integrated device for degreasing, cleaning, dehydrating, and drying screws used in rail transit, as described above, includes the following:

[0070] During loading, screws are placed in the loading bin 201 and fall onto the first conveyor belt 124 and are arranged horizontally.

[0071] During degreasing, the spray gun 111 first blows away impurities from the screw surface, the foaming machine 113 agitates the cleaning liquid into foam and sprays it onto the screw surface through the nozzle 114, and the vibrator 140 drives the first conveyor belt 124 to vibrate, so that the screw vibrates in the foam to remove oil.

[0072] During cleaning, the screws fall into the second conveyor belt 311 via the transfer bucket 130. Two sets of high-pressure water guns 303 sequentially rinse the foam on the surface of the screws. The partition 304 moves the screws to flip so as to achieve a thorough cleaning. The cleaning brush 322 in the brushing chamber 320 cleans the second conveyor belt 311 simultaneously.

[0073] During the drying process, the cleaned screws enter the drying cylinder 401, which rotates and introduces high-temperature gas to dehydrate and dry the screws.

[0074] Specifically, the above method integrates the processes of feeding, degreasing, cleaning, drying, and storage into the same device and allows them to flow in sequence.

[0075] Based on the above embodiments, this method achieves automatic transfer of each station through the process connection between the transfer bucket 130 and the inclined plate. It can complete the continuous, efficient and clean treatment of oil stains on the screw surface without manual intervention. The overall processing cycle is compact and energy consumption and manual input are significantly reduced.
