Description

Technical Field

[0001] The invention relates to the technical field of solvent filtering and processing, in particular to an automobile paint solvent filtering system. Background Art

[0002] Automobile paint solvent refers to the chemical liquid used to prepare automobile paint. It mainly plays the role of dissolving or dispersing film-forming substances, so that the paint can be evenly applied to the surface of the car, and then a protective and decorative coating is formed. In addition, the solvent can also adjust the viscosity of the paint to make it suitable for construction methods such as spraying, and affect the drying speed and the performance of the final coating. During the production, storage or transportation of automobile paint solvents, impurities such as solid particles and metal debris will be mixed into the solvent. If these impurities enter the paint spraying system or are directly applied to the car body, they will cause defects in the paint surface, such as graininess, orange peel effect, sagging, etc., affecting the quality and aesthetics of the paint surface. Impurities will also damage the spraying equipment, such as clogging the spray gun and damaging the pump body and other parts. Therefore, automobile paint solvents need to be filtered before use.

[0003] The existing filtration method is to first filter through a bag filter or a paper filter to remove relatively large particles, and then use a membrane filter to remove fine particles to achieve higher purity requirements. Among them, when using a bag filter for filtration, the solvent to be filtered is passed into the filter bag of the filter, and at the beginning of the filtration, the liquid is allowed to gradually enter the filter to achieve the filtration of the automotive paint solvent.

[0004] However, the following problems currently exist in the process of filtering automotive paint solvents: the existing filtering method only uses static filter bags for filtering, which mainly relies on the natural flow of the fluid and the fixed filter bags to capture particles, so the filtration efficiency is poor. Secondly, for the impurities left in the filter bags after filtration, it is necessary to disassemble the equipment and remove the bags before cleaning, which not only affects the solvent filtration efficiency, but also increases maintenance costs. Frequent disassembly will accelerate the aging and wear of the equipment and its components, shortening the service life of the equipment. Summary of the invention

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] During specific operation, the conveying portion 28 contacts the slip ring 22 and conveys the automobile paint solvent into the filter bag 24. At the same time, the driving portion 27 drives the slip ring 22 and the disc 23 to rotate synchronously, and the slip ring 22 and the disc 23 drive the filter bag 24 to rotate, thereby improving the filtration efficiency of the automobile paint solvent through the action of centrifugal force, and continuously inflating and pressurizing the filter bag 24 through the conveying portion 28, which can further assist in improving the efficiency of solvent filtration; the solvent filtered out of the filter bag 24 will fall into the inside of the tank body 11, and the filtered solvent can be taken out through the liquid outlet pipe for subsequent treatment.

[0037] The filter bag 24 needs to be cleaned regularly to ensure its filtering effect. The cleaning method is to first push the disc 23 to move vertically upward through the driving part 27, and the disc 23 will pass through the slip ring 22 to turn the filter bag 24 over. At this time, the filter bag 24 is located in the cylinder 21, and the disc 23 is connected to the conveying part 28. Then, the filter bag 24 is driven to rotate by the driving part 27 to separate impurities from the filter bag 24 through the action of centrifugal force, and the cleaned impurities are collected and processed by the cleaning part 26.

[0038] After the filter bag 24 is cleaned, the driving part 27 drives the disc 23 to move downward, and the disc 23 drives the filter bag 24 to turn over and recover, and then the filtering process of the automobile paint solvent can continue.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flip portion 25 includes a vertical pipe 250, and the vertical pipe 250 is coaxially fixedly installed on the bottom wall of the inner cavity of the tank body 11, and a spline sleeve 251 is movably installed in the vertical pipe 250. A spline shaft 252 is slidably installed in the spline sleeve 251, and the lower end of the spline shaft 252 passes through the spline sleeve 251 and is rotatably installed with a fixed disk 253. A fixing rod 254 is fixedly installed between the fixed disk 253 and the tank body 11, the upper end of the spline sleeve 251 is fixedly connected to the lower end of the disc 23, and the lower end of the spline sleeve 251 movably passes through the tank body 11, and a push-pull component for driving the spline sleeve 251 to move up and down is provided on the tank body 11.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying part 28 includes a tube body 280, and the tube body 280 is coaxially arranged in the cylinder 21. The upper end of the tube body 280 slides through the cylinder 21, and the upper right side of the tube body 280 is connected to a liquid inlet pipe 281, and the lower end of the tube body 280 is coaxially rotatably installed with a ring plate 282, the outer wall of the cylinder 21 is fixedly installed with a No. 2 cylinder 283, the telescopic section of the No. 2 cylinder 283 is fixedly installed with a No. 2 connecting plate 284, and the upper end of the tube body 280 is fixedly installed through the No. 2 connecting plate 284.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the driving portion 27 includes an annular baffle 270, the annular baffle 270 is fixedly installed on the upper part of the inner cavity of the tank body 11, a driving ring 271 is fixedly installed on the lower end of the slip ring 22, and the driving ring 271 is rotatably connected with the annular baffle 270, a driving disk 272 located below the fixed disk 253 is fixedly installed on the spline shaft 252, the outer diameter of the driving disk 272 is equal to the outer diameter of the driving ring 271, and a linkage member 6 for driving the driving ring 271 and the driving disk 272 to rotate synchronously and at the same speed is provided on the tank body 11.

[0043] like Figure 3 , Figure 4 and Figure 7 As shown, the linkage part 6 includes a shaft 60, the shaft 60 is rotatably mounted on the outer wall of the tank body 11 through a bearing seat, a servo motor 61 whose output shaft is fixedly mounted on the outer wall of the cylinder 21 and is fixedly connected to the shaft 60, and the drive disk 272 and the shaft 60 as well as the drive ring 271 and the shaft 60 are connected through a belt 62.

[0044] During specific operation, the No. 2 cylinder 283 pushes the tube body 280 to move downward, and the tube body 280 drives the ring plate 282 to be close to the slip ring 22, and then the external suction pump delivers the automobile paint solvent to the tube body 280 through the liquid inlet pipe 281, and the automobile paint solvent enters the filter bag 24 after passing through the tube body 280, the ring plate 282 and the slip ring 22. At the same time, the servo motor 61 drives the shaft 60 to rotate, and the shaft 60 drives the drive ring 271 to rotate through the belt 62, and the drive ring 271 drives the slip ring 22 to rotate. At the same time, the shaft 60 will also drive the spline shaft 252 and the drive ring 271 to rotate synchronously and at the same speed through the corresponding belt 62, and the spline shaft 252 will drive the disc 23 to rotate synchronously and at the same speed through the spline sleeve 251. The synchronous and simultaneous rotation of the slip ring 22 and the disc 23 will drive the filter bag 24 to rotate, so as to accelerate the filtration of the automobile paint solvent from the filter bag 24 by centrifugal means. At the same time, gas is filled from the upper end of the tube body 280 to continuously apply pressure to the inside of the filter bag 24, so as to further help improve the filtration efficiency of the automobile paint solvent.

[0045] The filter bag 24 needs to be cleaned of internal impurities regularly to ensure its filtering efficiency. The cleaning method is to first use the No. 2 cylinder 283 to pull the tube body 280 upward through the No. 2 connecting plate 284, and the tube body 280 drives the ring plate 282 to move up and reset. Then the No. 1 cylinder 255 pushes the spline sleeve 251 upward through the No. 1 connecting plate 256, and the spline sleeve 251 drives the small diameter section of the filter bag 24 to move upward through the slip ring 22 through the disc 23 to realize the turning over of the filter bag 24. At this time, the filter bag 24 is located in the cylinder 21, and the disc 23 is in conflict with the lower end of the ring plate 282. Then the drive unit 27 drives the filter bag 24 to rotate, so as to separate the impurities from the filter bag 24 and enter the cylinder 21 by centrifugation.

[0046] After cleaning is completed, the No. 1 cylinder 255 pulls the spline sleeve 251 downward through the No. 1 connecting plate 256, and the spline sleeve 251 drives the small diameter section of the filter bag 24 through the disc 23 to pass through the slip ring 22, so that the filter bag 24 is reset and is located in the tank body 11 again, and then the filtering process of the automobile paint solvent can continue.

[0047] like Figure 4 , Figure 5 and Figure 8 As shown, a circular hole is opened in the middle of the disc 23, a support plate 3 is fixedly installed on the upper part of the inner cavity of the spline sleeve 251, and air outlet holes 4 are evenly opened along the circumference of the spline shaft 252 on the upper part of the spline sleeve 251 and above the support plate 3. A sealing member 5 for sealing the circular hole on the disc 23 is provided on the support plate 3.

[0048] like Figure 4 , Figure 5 and Figure 8As shown, the seal 5 includes a support column 50. The middle part of the support plate 3 is slidably installed with a support column 50 coaxial with the disc 23. The upper end of the support column 50 is fixedly installed with a sealing block 51 for sealing the circular hole on the disc 23. A compression spring 52 sleeved on the support column 50 is fixedly installed between the lower end of the sealing block 51 and the support plate 3. A pushing assembly for pushing the sealing block 51 downward is arranged in the pipe body 280.

[0049] As Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in, the cleaning part 26 includes a vertical column 260. The upper end of the slip ring 22 is fixedly installed with a vertical column 260. A scraping plate 261 is fixedly installed on one side of the vertical column 260 away from the center of the slip ring 22. The scraping plate 261 is in a C-shaped structure. A discharge port 262 is opened on the cover plate 20. The lower end of the cover plate 20 is fixedly installed with an L-shaped pipe 263 communicated with the discharge port 262 and located above the annular baffle 270. The left end of the horizontal section of the L-shaped pipe 263 penetrates through the tank body 11.

[0050] As Figure 4 and Figure 8 As shown in, the pushing assembly includes a push rod 53. The lower part of the inner cavity of the pipe body 280 is coaxially and fixedly installed with a push rod 53 through a support rod. The lower end surface of the push rod 53 is lower than the lower end surface of the ring plate 282.

[0051] During specific operation, when the spline sleeve 251 moves upward to turn the filter bag 24 over and the disc 23 abuts against the ring plate 282, the push rod 53 will push the sealing block 51 and the support column 50 to move downward, so that the circular hole is opened, and at the same time, the compression spring 52 is compressed. At this time, the pipe body 280 is inflated, and the gas enters the spline sleeve 251 through the circular hole and blows to the filter bag 24 through the air outlet hole 4 to assist in removing impurities from the filter bag 24 that rotates and removes impurities by centrifugal force, thereby improving the cleaning efficiency.

[0052] During the process of the driving part 27 driving the filter bag 24 to rotate to clean impurities, the slip ring 22 will drive the scraping plate 261 to rotate circumferentially through the vertical column 260. The scraping plate 261 will scrape the impurities at the cleaning position to the discharge port 262. An external suction machine sucks air through the L-shaped pipe 263 to suck out the impurities in the cylinder 21, so that the impurities can be cleaned in time to reduce subsequent cleaning and maintenance.

[0053] After the filter bag 24 is cleaned, the first cylinder 255 pulls the filter bag 24 to reset through the first connecting plate 256. At this time, the air outlet hole 4 of the spline sleeve 251 is located in the vertical pipe 250, and the lower end of the support column 50 abuts against the upper end of the spline shaft 252 to ensure the sealing of the circular hole.
