Description

Technical Field

[0001] This invention relates to the field of brake fluid processing technology, specifically to a brake fluid processing method and a brake fluid processing apparatus. Background Technology

[0002] Motor vehicle brake fluid, commonly known as brake oil, is an important component of the automotive braking system. In the preparation process of existing borate ester type synthetic brake fluid, materials such as triethylene glycol monomethyl ether, diethylene glycol, boric acid, triethylene glycol monobutyl ether, diethanolamine, sodium benzoate, and sodium isooctanoate are added to the reaction vessel in proportion. Under uniform stirring, activated carbon is used to adsorb impurities. Before passing through the anion and cation exchange resin bed, the activated carbon and impurities are filtered out by a filter press.

[0003] Chinese patent CN115645981B discloses a brake fluid processing device, relating to the field of fine chemical automotive chemicals technology, including an isolation hood, a processing chamber, an intermittent stirring mechanism, and an opening and closing mechanism. This invention, by setting an intermittent stirring mechanism and an opening and closing mechanism on the isolation hood, utilizes the intermittent variable speed rotation of the drive motor output. The rotation of the turbulence belt itself creates a flexible agitation with the activated carbon in the material. After the granular activated carbon contacts the end face of the turbulence belt, it slides out tangentially along the surface, ensuring the integrity of the granular activated carbon. The output shaft of the drive motor also synchronously drives the upward-turned stirring plate to reciprocate rapidly, achieving efficient and uniform stirring. The activated carbon, having adsorbed impurities and maintained good integrity, quickly settles into the processing chamber through the opened stirring plate, achieving efficient recovery of the activated carbon and preparing it for recycling. This eliminates the need to evacuate the reactor to remove residual brake fluid preparation raw materials; the activated carbon can be recovered and reused under closed conditions, avoiding the degradation of the performance of residual brake fluid.

[0004] Although the above technical solution can use granular activated carbon for adsorption and filtration, the filtered brake fluid will accumulate and clog the screen when discharged, resulting in slow discharge and affecting discharge efficiency. However, brake fluid will still adhere to the surface of the granular activated carbon during discharge, which is difficult to remove and causes production losses. Summary of the Invention

[0005] To address the problems existing in the current technology, this application provides a method for processing brake fluid. The circulating flow purification device can effectively improve the discharge efficiency and reduce production losses.

[0006] To address the problems of existing technologies, this invention provides a method for processing brake fluid. The brake fluid processing method utilizes a brake fluid processing apparatus, including a circulating flow purification device mounted on a frame. The circulating flow purification device includes a circulating flow pipe mounted on the frame, with several circulating storage tanks installed on the circulating flow pipe. The circulating flow pipe and the circulating storage tanks are interconnected. A lifting platform is mounted above the circulating flow pipe, and a rotary drive pipe is mounted on the lifting platform. The rotary drive pipe has a flow cavity inside, and a rotary flow mechanism and an activated carbon filter box are mounted on the rotary drive pipe. The activated carbon filter box stores activated carbon and is connected to the flow cavity of the rotary drive pipe. A rotary drive device is also mounted on the lifting platform, and the rotary drive device is connected to the rotary drive pipe. A filter discharge mechanism is also installed at the discharge end of the circulating flow pipe.

[0007] The processing method for brake fluid includes the following steps:

[0008] S1. First, add activated carbon to the activated carbon filter box, and then use the lifting mounting platform to place the rotating flow mechanism and the activated carbon filter box together into the circulation pipe.

[0009] S2. Add brake fluid mixtures of different proportions to the circulating reservoir. To mix the brake fluid, the rotary drive device drives the rotary drive tube to rotate. The rotary drive tube drives the rotary flow mechanism and the activated carbon filter box to rotate synchronously. When the rotary flow mechanism rotates, it drives the brake fluid inside the circulating reservoir to circulate in a spiral, so that the brake fluid is mixed quickly. At the same time, when the brake fluid passes through the activated carbon inside the activated carbon filter box, the activated carbon will adsorb and filter the impurities in the brake fluid. The brake fluid is repeatedly filtered and mixed through this step.

[0010] S3. After the brake fluid is mixed, the circulation pipe opens the discharge end and the mixed brake fluid is transported to the area to be treated through the filter discharge mechanism. At the same time, the activated carbon filter box will continue to rotate. The centrifugal force of the rotation can effectively and quickly remove the brake fluid attached to the activated carbon.

[0011] S4. After the brake fluid is discharged, the cleaning fluid is transported to the flow cavity of the rotary drive tube through the conveying equipment. The flow cavity of the rotary drive tube guides the cleaning fluid to the inside of the activated carbon filter box. The cleaning fluid will clean the activated carbon. After the activated carbon is cleaned, the activated carbon filter box will continue to rotate. The centrifugal force of the rotation can effectively remove the cleaning fluid adhering to the activated carbon.

[0021] The advantages of this application compared to the prior art are:

[0022] Different proportions of brake fluid mixtures are added to the circulating reservoir. To mix the brake fluid, a rotary drive device rotates the rotary drive tube, which in turn drives the rotary flow mechanism and activated carbon filter box to rotate synchronously. As the rotary flow mechanism rotates, it causes the brake fluid inside the circulating reservoir to circulate in a spiral pattern, allowing for rapid mixing. Simultaneously, as the brake fluid passes through the activated carbon inside the activated carbon filter box, the activated carbon adsorbs and filters impurities from the brake fluid. This process of repeated filtration and mixing is repeated. Once the brake fluid is properly mixed, the circulating flow tube opens its outlet end, and the mixed brake fluid is transported to the processing area through the filtration and discharge mechanism. Meanwhile, the activated carbon filter box continues to rotate, and the centrifugal force of the rotation quickly removes brake fluid adhering to the activated carbon, effectively improving discharge efficiency and reducing production losses.

Detailed Implementation

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 10 As shown:

[0039] A method for processing brake fluid, comprising a brake fluid processing device, including a circulating flow purification device mounted on a frame 1, the circulating flow purification device including a circulating flow pipe 3 mounted on the frame 1, several circulating storage tanks 2 mounted on the circulating flow pipe 3, the circulating flow pipe 3 and the circulating storage tanks 2 being interconnected, a lifting mounting platform 4 mounted above the circulating flow pipe 3, a rotary drive pipe 5 mounted on the lifting mounting platform 4, a flow cavity 51 provided inside the rotary drive pipe 5, a rotary flow mechanism 6 and an activated carbon filter box 7 mounted on the rotary drive pipe 5, the activated carbon filter box 7 storing activated carbon inside, the activated carbon filter box 7 being interconnected with the flow cavity 51 of the rotary drive pipe 5, a rotary drive device 8 also mounted on the lifting mounting platform 4, the rotary drive device 8 being drively connected to the rotary drive pipe 5, and a filter discharge mechanism 9 also mounted at the discharge end of the circulating flow pipe 3;

[0040] The processing method for brake fluid includes the following steps:

[0041] S1. First, add activated carbon to the activated carbon filter box 7, and then place the rotating flow mechanism 6 and the activated carbon filter box 7 into the circulation pipe 3 together through the lifting mounting platform 4.

[0042] S2. Add brake fluid mixtures of different proportions to the circulating reservoir 2. To mix the brake fluid, the rotary drive device 8 drives the rotary drive tube 5 to rotate. The rotary drive tube 5 drives the rotary flow mechanism 6 and the activated carbon filter box 7 to rotate synchronously. When the rotary flow mechanism 6 rotates, it drives the brake fluid inside the circulating reservoir 2 to circulate in a spiral, so that the brake fluid is mixed quickly. At the same time, when the brake fluid passes through the activated carbon inside the activated carbon filter box 7, the activated carbon will adsorb and filter the impurities in the brake fluid. The brake fluid is repeatedly filtered and mixed through this step.

[0043] S3. After the brake fluid is mixed, the circulation pipe 3 opens the discharge end and the mixed brake fluid is transported to the area to be treated through the filter discharge mechanism 9. At the same time, the activated carbon filter box 7 will continue to rotate. The centrifugal force of the rotation can effectively and quickly remove the brake fluid attached to the activated carbon.

[0044] S4. After the brake fluid is discharged, the cleaning fluid is transported to the flow cavity 51 of the rotary drive tube 5 through the conveying device. The flow cavity 51 of the rotary drive tube 5 guides the cleaning fluid to the interior of the activated carbon filter box 7. The cleaning fluid will clean the activated carbon. After the activated carbon is cleaned, the activated carbon filter box 7 will continue to rotate. The centrifugal force of the rotation can effectively remove the cleaning fluid attached to the activated carbon.

[0045] like Figure 2 and Figure 3 As shown:

[0046] The circulating liquid storage tank 2 is installed on the frame 1. The bottom of the circulating liquid storage tank 2 is shaped like a lower bucket. The inner wall of the bottom of the circulating liquid storage tank 2 is covered with first spiral guide vanes 21. The top of the circulating liquid storage tank 2 is provided with a feed inlet 22. The side of the circulating liquid storage tank 2 is provided with a first circulation port 23. The bottom of the circulating liquid storage tank 2 is provided with a second circulation port 24. Both the first circulation port 23 and the second circulation port 24 are connected to the circulation pipe 3.

[0047] The feed inlet 22 at the top of the circulating reservoir 2 is used to add brake fluid mixtures of different proportions to the circulating reservoir 2. When the brake fluid needs to be mixed, the rotating drive device 8 drives the rotating drive pipe 5 to rotate. The rotating drive pipe 5 drives the rotating flow mechanism 6 and the activated carbon filter box 7 to rotate synchronously. When the rotating flow mechanism 6 rotates, it drives the brake fluid inside the circulating reservoir 2 to flow into the circulating flow pipe 3 from the second circulation port 24. When the brake fluid flows to the second circulation port 24, it passes through the first spiral guide vane 21. The first spiral guide vane 21 guides the flowing brake fluid to rotate in a spiral. The rotating brake fluid will mix the brake fluid quickly. The circulating flow pipe 3 then sends the brake fluid from the first circulation port 23 into the circulating reservoir 2, forming a circulating flow and mixing.

[0048] like Figure 1 and Figure 2 As shown:

[0049] The circulation pipe 3 is installed on the frame 1. The upper end of the circulation pipe 3 is provided with several third circulation ports 32, the lower end of the circulation pipe 3 is provided with several fourth circulation ports 33, and the bottom of the circulation pipe 3 is provided with a discharge port, on which a flow control valve 31 is installed.

[0050] The third circulation port 32 of the circulation pipe 3 is used to connect to the first circulation port 23, the fourth circulation port 33 is used to connect to the second circulation port 24, the outlet of the circulation pipe 3 is used for discharging material, and the flow control valve 31 is used to control the discharge.

[0051] like Figure 2 and Figure 4 As shown:

[0052] The lifting mounting platform 4 includes a guide bracket 41 mounted on the frame 1, a limit lifting platform 42 mounted on the guide bracket 41, a winding machine 43 mounted on the top of the guide bracket 41, a connecting rope 44 mounted on the winding machine 43, and one end of the connecting rope 44 away from the winding machine 43 connected to the limit lifting platform 42.

[0053] When it is necessary to disassemble the activated carbon filter box 7 and the rotary flow mechanism 6, the staff releases the fixing of the limit lifting mechanism, and then uses the winding machine 43 to wind up the connecting rope 44. When the connecting rope 44 is wound up, it will drive the limit lifting platform 42 to rise along the guide bracket 41. When the limit lifting platform 42 rises, it will drive the rotary drive pipe 5, the activated carbon filter box 7 and the rotary flow mechanism 6 to rise synchronously and disengage from the circulation pipe 3, which can effectively improve the convenience of disassembly and installation.

[0054] like Figure 2 , Figure 5 and Figure 6 As shown:

[0055] The rotary flow mechanism 6 includes several suction fan blades 61 mounted on the rotary drive pipe 5. A flow guide mounting block 62 is mounted on the upper end of the drive pipe. The flow guide mounting block 62 is conical. A limit bracket 63 is also mounted on the drive pipe. The limit bracket 63 slides against the inner wall of the circulation pipe 3.

[0056] The brake fluid needs to be mixed. The rotary drive device 8 drives the rotary drive tube 5 to rotate. The rotary drive tube 5 drives the multiple suction fan blades 61 of the rotary flow mechanism 6 to rotate. When the suction fan blades 61 rotate, they drive the brake fluid inside the circulation pipe 3 to flow rapidly. The limiting bracket 63 is used to stabilize and limit the position of the rotary drive tube 5 inside the circulation pipe 3 to ensure the stability of the rotation of the rotary drive tube 5. The flow guide mounting block 62 is conical and is used to guide the diffusion of the flowing brake fluid, so that the brake fluid flows to the third circulation port 32 of the circulation reservoir 2.

[0057] The rotary drive device 8 includes a rotary driver 81 mounted on the limit lifting platform 42, a drive gear 82 mounted on the rotary driver 81, and a driven gear 83 mounted on the rotary drive tube 5. The driven gear 83 meshes with the drive gear 82. When it is necessary to drive the rotary drive tube 5 to rotate, the operator will drive the drive gear to rotate through the rotary driver 81. When the drive gear rotates, it will drive the driven gear 83 to rotate, and when the driven gear 83 rotates, it will drive the rotary drive tube 5 to rotate synchronously.

[0058] like Figures 6 to 9 As shown:

[0059] The activated carbon filter box 7 is installed on the rotary drive tube 5. The bottom of the activated carbon filter box 7 is provided with an upper bucket shape. The bottom surface of the activated carbon filter box 7 is covered with several second spiral guide vanes 71. The bottom of the activated carbon filter box 7 is also installed with a first filter layer 72. The interior of the activated carbon filter box 7 is provided with several dividing screen plates 73. The activated carbon filter box 7 is also provided with guide holes 74. The upper end of the activated carbon filter box 7 is provided with a feeding port. The side of the activated carbon filter box 7 is provided with several discharging ports. The upper and lower ends of the activated carbon filter box 7 are also provided with threaded mounting sleeves 75. The feeding port of the activated carbon filter box 7 is provided with an elastic pressing cover plate 77. The discharging port of the activated carbon filter box 7 is provided with a synchronous sealing mechanism 76.

[0060] The internal dividing sieve plate 73 of the activated carbon filter box 7 is used to divide the internal storage cavity into multiple storage cavities for filling activated carbon. The elastic pressing cover plate 77 is used to block the feed port of the activated carbon filter box 7 and to compress the filled activated carbon. The synchronous sealing mechanism 76 is used to block the discharge port of the activated carbon filter box 7. When the rotary drive pipe 5 rotates, it will drive the activated carbon filter box 7 and the rotary flow mechanism 6 to rotate synchronously. When the rotary flow mechanism 6 rotates, it will cause the brake fluid to flow in the circulation pipe 3. The brake fluid will enter the interior from the first filter layer 72 at the bottom of the activated carbon filter box 7, and the activated carbon will pass through the filter. When the filter box 7 rotates, the second spiral guide vane 71 at the bottom can effectively improve the flow of the brake fluid. When the activated carbon filter box 7 rotates, the activated carbon inside will rotate synchronously. The activated carbon inside the activated carbon filter box 7 will adsorb and purify the incoming brake fluid. The purified brake fluid passes through the elastic pressing cover 77. After the brake fluid is purified, the discharge end of the circulation pipe 3 is opened to discharge the brake fluid. When the brake fluid is discharged, the activated carbon filter box 7 continues to rotate. The centrifugal force of the rotation can effectively and quickly remove the brake fluid attached to the activated carbon, which can effectively improve the discharge efficiency.

[0061] like Figure 7 and Figure 8 As shown:

[0062] The synchronous sealing mechanism 76 includes a mounting bracket 761 installed at the bottom of the activated carbon filter box 7. A first adjusting bolt 762 is installed on the mounting bracket 761. The first adjusting bolt 762 is threadedly connected to the threaded mounting sleeve 75. The mounting bracket 761 is covered with limit plates 763, and the limit plates 763 correspond one-to-one with the discharge port of the activated carbon filter box 7.

[0063] When the activated carbon inside the activated carbon filter box 7 needs to be replaced after long-term use, the activated carbon filter box 7 is raised and disconnected from the circulation pipe 3 by the lifting mounting platform 4. The operator then rotates the first adjusting bolt 762. When the first adjusting bolt 762 rotates, it will drive the mounting bracket 761 to move downward. When the mounting bracket 761 moves downward, it will drive the limit plate 763 to move synchronously. When the limit plate 763 moves, it will open the discharge port of the activated carbon filter box 7, and the activated carbon inside the activated carbon filter box 7 will be discharged from the discharge port, effectively improving the material handling efficiency.

[0064] like Figure 8 and Figure 9 As shown:

[0065] The elastic press-fit cover 77 includes a docking mounting frame 771 installed on the top of the activated carbon filter box 7. The docking mounting frame 771 has several mounting slots, each of which is equipped with a sliding mounting bracket 774. A second adjusting bolt 773 is installed on the docking mounting frame 771 and is threadedly connected to a threaded mounting sleeve 75. Several limiting guide posts 772 are also installed on the docking mounting frame 771 and are connected to the sliding mounting bracket 774. A spring 776 is installed between the sliding mounting bracket 774 and the docking mounting frame 771. A second filter layer 777 is also installed on the surface of the sliding mounting bracket 774.

[0066] After adding an appropriate amount of activated carbon from the feed port of the activated carbon filter box 7, the operator rotates the second adjusting bolt 773. When the second adjusting bolt 773 rotates, it will cooperate with the threaded mounting sleeve 75 to push the docking mounting frame 771 to move. The limiting guide post 772 on the docking mounting frame 771 is used to limit and guide the movement, so that the docking mounting frame 771 is in contact with the feed port of the activated carbon filter box 7, and the second filter layer 777 is in contact with the activated carbon inside the activated carbon filter box 7. When the second filter layer 777 is in contact with the activated carbon, the spring 776 will be squeezed to form a pressing force, which will compact the activated carbon inside, effectively preventing the activated carbon from being damaged by impact during rotation.

[0067] like Figure 2 and Figure 10 As shown:

[0068] The filter discharge mechanism 9 includes a guide bucket 91 installed at the bottom discharge port of the circulation pipe 3. The bottom of the guide bucket 91 is provided with a first liquid outlet 911, and the side of the guide bucket 91 is provided with a second liquid outlet 912. Both the first liquid outlet 911 and the second liquid outlet 912 are provided with control valves 96. A filter plate 92 is also installed inside the guide bucket 91. A fixed bracket 93 is also installed inside the guide bucket 91. A flow fan 94 is installed on the fixed bracket 93. A scraper 95 is also installed at the bottom of the flow fan 94. The scraper 95 abuts against the surface of the filter plate 92.

[0069] When the outlet of the circulation pipe 3 is opened, the brake fluid inside will enter the interior of the guide bucket 91. The control valve 96 opens the first outlet 911, and the brake fluid will pass through the filter plate 92 and be discharged from the first outlet 911. The first outlet 911 will transport the discharged brake fluid to the area to be treated. When the brake fluid flows, it will drive the flow fan 94 to rotate synchronously. When the flow fan 94 rotates, it will drive the scraper 95 to rotate with the surface of the filter plate 92, which can effectively prevent the filtered impurities from clogging the filter plate 92 and effectively ensure the feeding efficiency. After the brake fluid is discharged, the cleaning fluid is transported to the circulation cavity 51 of the rotary drive pipe 5 through the conveying equipment. The circulation cavity 51 of the rotary drive pipe 5 guides the cleaning fluid to the interior of the activated carbon filter box 7. The cleaning fluid will clean the activated carbon. At the same time, the first outlet 911 is closed and the second outlet 912 is opened, and the cleaning fluid will be discharged from the second outlet 912. When the cleaning fluid flows, it will also discharge the impurities on the filter plate 92 to the area to be treated.

[0070] like Figure 11 and Figure 12 As shown, a mixing mechanism 25 is installed inside the circulating liquid storage tank 2. The mixing mechanism 25 is located above the first spiral guide vane 21. The mixing mechanism 25 includes a rotating shaft 251, which is horizontally installed inside the circulating liquid storage tank 2.

The side of the second mixing plate 254 closest to the rotating shaft 251 is connected to the inner wall of the groove 253 by several first return springs 255. Sliding holes 256 are symmetrically provided at the upper and lower ends of the first mixing plate 252. Sliding columns 257 are slidably installed in the sliding holes 256. One end of the sliding column 257 is connected to the inner wall of the sliding hole 256 via the second return spring 258. The other end of the sliding column 257 extends to the outside of the sliding hole 256 and is provided with several mixing rods 259. The mixing rods 259 are perpendicular to the sliding column 257. The sliding hole 256 and the sliding groove 253 are connected through a through hole 260. A drive rod 261 is slidably arranged in the through hole 260. One end of the drive rod 261 is connected to the side wall of the second mixing plate 254 near the rotating shaft 251. The other end of the drive rod 261 is provided with a first inclined surface. The length of the drive rod 261 near the rotating shaft 251 is less than the length of the drive rod 261 away from the rotating shaft 251. A groove 262 is provided on the side of the sliding column 257 near the through hole 260. The groove 262 has a triangular cross section. The inner wall of the groove 262 is adapted to the outer wall of the end of the drive rod 261 near the rotating shaft 251.

[0071] Initially, under the action of the first return spring 255, the second mixing plate 254 is mostly within the groove 253, while the sliding column 257 is located within the sliding hole 256. When brake fluid flows from the first circulation port 23 into the circulation reservoir 2, the brake fluid drives the first mixing plate 252 and the second mixing plate 254 to rotate. The rotation of the first mixing plate 252 and the second mixing plate 254 agitates the brake fluid in the circulation reservoir 2. The sliding column 257 rotates with the first mixing plate 252, driving the mixing rod 259 to rotate within the circulation reservoir 2, thereby improving the mixing effect. Simultaneously, the process of adding the mixture from the inlet 22 also drives the first mixing plate 252 and the second mixing plate 254 to rotate, eliminating the need for additional power to drive the first mixing plate 252 and the second mixing plate 254, thus saving energy. As the brake fluid circulation speed increases... As the speed increases, the rotation speed of the first mixing plate 252 and the second mixing plate 254 gradually increases. Under the action of centrifugal force, the sliding column 257 gradually slides outward from the sliding hole 256, and the second return spring 258 is stretched, thereby changing the position of the mixing rod 259, expanding the agitation and mixing range, and further improving the mixing effect, making the brake fluid more uniformly mixed. At the same time, as the sliding column 257 slides outward, the groove 262 drives the drive rod 261 to slide away from the sliding hole 256, and the drive rod 261 drives the second mixing plate 254 to slide away from the sliding groove 253, thereby increasing the exposed area of ​​the second mixing plate 254, thereby increasing the contact area between the second mixing plate 254 and the brake fluid. The faster the brake fluid circulation speed, the larger the contact area between the second mixing plate 254 and the brake fluid, which accelerates the mixing speed and greatly improves the mixing efficiency of the brake fluid.
