Description

Technical Field

[0001] This utility model relates to the field of spray booth technology, and in particular to a workpiece cleaning system with water circulation. Background Technology

[0002] In industries such as machining and pre-coating treatment, workpieces typically require cleaning to remove surface oil, debris, and other impurities before proceeding to the next process. Currently, the most common cleaning method involves using a spray system to rinsing the workpieces on a suspended conveyor chain. However, the filtration devices often employ fixed screens or cartridges, which are easily and quickly clogged by oil sludge, metal debris, and other impurities. This leads to reduced filtration efficiency, not only clogging the spray nozzles and affecting cleaning effectiveness but also requiring frequent shutdowns for cleaning, resulting in low production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a workpiece cleaning system with water circulation that facilitates the cleaning of filter residue.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A workpiece cleaning system with water circulation includes: a spray chamber, a suspended transport line at the top of the spray chamber allowing workpieces to pass through, the workpieces being suspended on the suspended transport line, a spray pipe inside the spray chamber for rinsing the workpieces, a filter device outside the spray chamber, a return pipe between the filter device and the spray chamber for guiding water used to rinse the workpieces into the filter device, a conveying device between the spray pipe and the filter device for conveying filtered water back to the spray pipe, the filter device including a filter tank, a U-shaped drive chain assembly inside the filter tank, the outlet of the return pipe facing the center of the drive chain assembly, a filter cloth covering the outer side of the drive chain assembly, an opening on one side wall of the filter tank, a portion of the drive chain assembly and the filter cloth being disposed outside the opening, and a scraper on the outer wall of the filter tank for scraping off residue from the filter cloth.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] like Figures 1 to 8As shown, a workpiece cleaning system with water circulation includes: a spray chamber 1, a suspended transport line 2 at the top of the spray chamber 1 for passing workpieces through the spray chamber 1, the workpieces being suspended on the suspended transport line 2, a spray pipe 3 inside the spray chamber 1 for rinsing the workpieces, a filter device 4 outside the spray chamber 1, a return water pipe 5 between the filter device 4 and the spray chamber 1 for guiding the water used to rinse the workpieces to the filter device 4, and a water return pipe 5 between the spray pipe 3 and the filter device 4 for conveying the filtered water... The conveying device 6 delivers water to the spray pipe 3. The filtration device 4 includes a water filter tank 41. A U-shaped transmission chain assembly 42 is installed inside the water filter tank 41. The outlet of the return water pipe 5 is located towards the middle of the transmission chain assembly 42. A filter cloth 43 is installed on the transmission chain assembly 42 and covers its outer side. An opening 411 is provided on one side wall of the water filter tank 41. Part of the transmission chain assembly 42 and the filter cloth 43 are located outside the opening 411. A scraper 44 is provided on the outer wall of the water filter tank 41 to scrape off the residue on the filter cloth 43.

[0028] In use, this utility model forms a closed loop through the spray chamber 1, return water pipe 5, filter device 4, conveying device 6, and spray pipeline 3 to filter the rinsing water, which can then be reused, reducing water consumption. At the same time, the U-shaped transmission chain assembly 42 drives the filter cloth 43 to continuously carry the residue out of the filter pool 41. The scraper 44 automatically cleans the surface of the filter cloth 43 during equipment operation, removing the filter residue. This achieves simultaneous filtration and residue removal with high residue removal efficiency. Furthermore, the filter cloth 43 can be removed for easy replacement after damage.

[0029] The scraper 44 includes a frame 441, on which a scraper portion 442 is provided that can adhere to one side of the filter cloth 43. The frame 441 is also provided with a guide plate 443 that can receive and guide residue. The scraper portion 442 can closely adhere to one side of the moving filter cloth 43, ensuring that the residue (such as oil, metal shavings, and impurity clumps) attached to the filter cloth 43 can be effectively scraped off, minimizing residue, maintaining the cleanliness and permeability of the filter cloth 43, and facilitating subsequent filtration by the filter cloth 43.

[0030] The outer wall of the filter tank 41 is also provided with a washing assembly 45. The washing assembly 45 includes a rotating rod 451 rotatably connected to the outer wall of the filter tank 41 and a driving component 452 that drives the rotating rod 451 to rotate. A roller brush part 453 that can fit against the outer side of the filter cloth 43 is detachably connected to the rotating rod 451. The roller brush part 453 is located inside the scraper 44. The roller brush part 453 rotates under the drive of the driving component 452 and fits tightly against the outer surface of the filter cloth 43, effectively removing stubborn deposits that the scraper 44 cannot completely remove, restoring the porosity and water permeability of the filter cloth 43. The filter cloth 43 first has large particles scraped off by the scraper 44, and then small particles or oil stains are washed by the washing assembly 45, achieving double cleaning and avoiding a large amount of particles in the pores of the filter cloth 43.

[0031] The transmission chain assembly 42 includes multiple transmission rollers 421, which are spaced apart to form a U-shaped arrangement. Transmission gears 422 are disposed on the sides of each transmission roller 421, and a transmission chain 423 connects the transmission gears 422. A transmission belt 424 is connected to the middle of each transmission roller 421, and the filter cloth 43 is fitted against the transmission belt 424. A transmission motor is connected to the end of any one of the transmission rollers 421 to drive its rotation. When the transmission motor starts, it drives the transmission roller 421 connected to its output shaft. The rotation of the transmission roller 421 drives the transmission gears 422, which in turn causes the transmission belt 424 to move, thus causing the filter cloth 43 to move along with the transmission belt 424.

[0032] A separation component 46 is provided between the water filtration tank 41 and the filter cloth 43, enabling the filter cloth 43 to separate from the transmission belt 424 at the opening 411 section. The separation component 46 includes multiple first rotating rollers 461, which are disposed on the inner side of the filter cloth 43 to partially separate the filter cloth 43 from the transmission belt 424. By using the multiple first rotating rollers 461 disposed on the inner side of the filter cloth 43, the filter cloth 43 is actively supported at the opening 411 section, creating a physical separation gap between it and the transmission belt 424. This facilitates cleaning by the washing component 45 and avoids residue clogging caused by the filter cloth 43 adhering to the transmission belt 424.

[0033] The filter tank 41 is also equipped with two connecting rods 47 arranged along its length. Each connecting rod 47 has an arc-shaped top pressure plate 471 at its end. The top pressure plate 471, in conjunction with the corresponding transmission roller 421, presses the transmission belt 424 along the path of the two connecting rods 47 against the edge of the filter cloth 43. The arc-shaped design of the top pressure plate 471 closely fits the outer contour of the transmission roller 421, and, in conjunction with the connecting rods 47, continuously presses the edge of the filter cloth 43 during its movement.

[0034] The return water pipe 5 includes multiple vertically arranged first pipe bodies 51. The upper end of each first pipe body 51 is connected to the spray chamber 1, and the lower end of each first pipe body 51 is connected to a water collection pipe 52. The lower end of the water collection pipe 52 is provided with multiple drain holes 521, which are spaced apart along the water collection pipe 52. This arrangement allows multiple drain holes 521 to drain water separately, so that the discharged wastewater can fall into the U-shaped part of the transmission belt 424, facilitating filtration by the filter cloth.

[0035] The conveying device 6 includes a water pump 61, the pumping end of which extends into the water filter tank 41, and the outlet end of the water pump 61 is connected to the spray pipe 3. The water pump 61 can draw filtered water to the spray pipe 3, from which the workpiece is sprayed again.

[0036] The water filtration tank 41 is equipped with a vertically arranged filter screen 7, which divides the water filtration tank 41 into a filtration zone 412 and a pumping zone 413. The conveying device 6 is located on one side of the pumping zone 413, and the transmission chain assembly 42 is located in the filtration zone 412. The function of the filter screen 7 is to perform secondary filtration. By using a finer mesh, it can perform secondary filtration, preventing residue from entering the pump and damaging the motor.

[0037] The water filter tank 41 is also provided with an outer cover 48 that can cover the scraper 44 and the washing assembly 45. The bottom of the outer cover 48 is open. The outer cover 48 can protect the scraper 44 and the washing assembly 45 and prevent them from being exposed.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
