Description

Technical Field

[0001] The invention relates to the field of paper bag filters, and more particularly to a drum type paper bag filter. Background Art

[0002] The paper bag filter is a cooling liquid filtering device used in metal grinding or other processing. It can effectively remove impurities in the solution. Its application in filtering and removing impurities in the solution and automatically replacing the filter cloth not only improves the work efficiency and effect, but also the drum paper bag filter relies on the gravity of the liquid to pass through the filter cloth and isolate the impurities, thereby achieving the purpose of purifying the liquid.

[0003] For example, the Chinese patent with the announcement number CN219481836U discloses a drum-type paper bag filter, which makes the connection shaft and the two rotating shafts quickly connected by making the two moving blocks and the limit block on the same side cooperate with the cross groove, so as to quickly and flexibly replace the paper bags, thereby improving the convenience of operation of the paper bag filter to a certain extent;

[0004] The core principle of the drum paper bag filter in the prior art is to isolate the impurities in the cutting fluid above the non-woven fabric through filter paper, and the clean liquid passes through the non-woven fabric into the water tank to separate and remove the impurities. However, in the actual operation process, the cutting fluid will produce a certain amount of foam during the flow process. The presence of foam will occupy the filtration space and reduce the effective filtration area of ​​the paper bag surface, thereby reducing the filtration efficiency of the paper bag filter, which will cause the impurities in the coolant to be unable to be removed in time, affecting the filtration and purification quality of the cutting fluid, and some foam adheres to the surface of the liquid level meter, causing the monitoring accuracy of the liquid level meter to be affected, thereby increasing the probability of accidental paper feeding, and further increasing the loss of paper bags during the filtration process.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 A drum paper bag filter comprises a body 11, a material storage box 12 is fixedly connected to the outer surface of the lower end of the body 11, a connecting pipe 27 is rotatably connected to the outer surface of the front end of the body 11, a water inlet cylinder 31 is fixedly connected to the rear end of the connecting pipe 27, a through hole 32 is opened on the outer surface of the water inlet cylinder 31, a fixed cylinder 29 is fixedly connected to the outer surface of the connecting pipe 27, and a foam removal component is arranged inside the fixed cylinder 29;

[0035] The foam removal component includes a guide groove 48 opened on the inner surface of the fixed cylinder 29, the guide groove 48 is in a circular ring shape, the inner surface of the guide groove 48 is rotatably connected to a rotating wheel 49, the outer surface of the rotating wheel 49 is fixedly connected to a mounting shaft 50, the outer surface of the mounting shaft 50 is fixedly connected to a top block 51, the top block 51 is a wedge-shaped structure, and the mounting shaft 50 is located directly below the water inlet cylinder 31.

[0036] The front end outer surface of the storage box 12 is fixedly connected with a liquid outlet pipe 18, the number of the top blocks 51 is several groups and distributed in a ring array, the lower end of the body 11 is connected to the interior of the storage box 12, the rear end outer surface of the water inlet cylinder 31 is fixedly connected with a connecting pipe 2 30, and the connecting pipe 2 30 is rotatably connected to the outer surface of the body 11, the number of the guide grooves 48 and the rotating wheels 49 are two groups and are symmetrically distributed, the outer surface of the fixed cylinder 29 is provided with through grooves 39, the number of the through grooves 39 is several groups and distributed in a ring array, and the inner side of the through groove 39 is fixedly connected with a blade 40.

[0037] By adopting the above technical scheme, when the machine tool cutting fluid is filtered through the paper bag 33 filter, the cutting fluid will produce a certain amount of foam during the flow process. Excessive foam will occupy the surface of the paper bag 33, reducing the effective filtering area, thereby causing the filtering efficiency to decrease. As the foam increases, the liquid cannot pass through the filter medium smoothly, causing the filtering speed to slow down. Therefore, it is necessary to remove the foam in the cutting fluid in time during the filtering process. For this purpose, a foam removing component is provided. After the cutting fluid to be cleaned is injected into the water inlet cylinder 31 through the connecting pipe 27, the cutting fluid will fall downward through the through hole 32 on the surface of the water inlet cylinder 31. In the process of falling downward, the cutting fluid will contact the top block 51 on the surface of the mounting shaft 50, and the foam in the cutting fluid will be broken by the top block 51. The guide groove 48 opened on the inner side of the fixed cylinder 29 supports the rotating wheel 49 for rotation. The mounting shaft 50 is movably supported, and the top block 51 adopts a wedge-shaped structure that can puncture and crush the foam in the cutting fluid through its corners, thereby effectively improving the foam removal effect. After the cutting fluid falls into the fixed cylinder 29, it will flow out from the through groove 39 on the surface of the fixed cylinder 29 to the outer surface of the paper bag 33 on the lower side of the fixed cylinder 29. The blade 40 on the inner side of the through groove 39 can not only have a certain buffering effect on the water flow, but also the tip of the blade 40 can have a secondary crushing and clearing effect on the remaining foam in the cutting fluid, thereby effectively reducing the adhesion of foam on the surface of the paper bag 33. By ensuring the filtration area of ​​the paper bag 33, the filtration efficiency can be effectively improved. The partition 55 is used to separate the space inside the storage box 12, so that the cutting fluid and impurities can be stored separately through the storage box 12, and the liquid outlet pipe 18 can discharge the cutting fluid inside the storage box 12 for subsequent treatment.

[0038] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the front end outer surface of the body 11 is fixedly connected to a liquid inlet box 21, the upper end of the liquid inlet box 21 is open, the lower end outer surface of the liquid inlet box 21 is fixedly connected to a liquid guide tube 20, the lower end of the liquid guide tube 20 is fixedly connected to a rotary joint 19, the rotary joint 19 is rotatably connected to the front end outer surface of the connecting pipe 27, and the inner surface of the storage box 12 is fixedly connected to a partition 55.

[0039] A storage box 13 is fixedly connected to the outer surface of the left end of the body 11, and the upper end of the storage box 13 is open. A mounting groove 15 is opened on the outer surface of the storage box 13, and the upper end of the mounting groove 15 penetrates to the upper side of the storage box 13. A movable shaft 14 for placing a paper bag 33 is movably connected to the inner side of the mounting groove 15.

[0040] A filter assembly is provided on the inner side of the machine body 11, and the filter assembly includes a support rod 1 34 and a support rod 2 36 fixedly connected to the inner side of the machine body 11, the support rod 1 34 is located on the upper side of the support rod 2 36, and the outer surfaces of the support rod 1 34 and the support rod 2 36 are rotatably connected to guide rollers 1 35 and 2 37 respectively, and the number of guide rollers 1 35 and guide rollers 2 37 is two groups and they are symmetrically distributed, and the outer surfaces of the guide rollers 1 35 and the guide rollers 2 37 are rotatably connected to a support net 38, and the support net 38 is located on the outside of the fixed cylinder 29.

[0041] By adopting the above technical solution, when filtering the cutting fluid, the cutting fluid to be processed is firstly continuously injected into the liquid inlet box 21, and then the cutting fluid is injected into the rotary joint 19 through the liquid guide tube 20 under the action of gravity. The rotary joint 19 and the connecting pipe 27 are rotated and sealed, so that the connecting pipe 27 can maintain good sealing with the rotary joint 19 during the rotation process. The cutting fluid is injected into the water inlet cylinder 31 through the connecting pipe 27 and discharged outward from the through hole 32 on the surface of the water inlet cylinder 31. The left side of the body 11 is fixedly connected with a storage box 13 for storing and placing the movable shaft 14. The mounting groove 15 on the surface of the storage box 13 is used to support the rotation of the movable shaft 14. The mounting groove 15 The movable shaft 14 can be installed quickly and conveniently, and the clean paper bag 33 is wound around the outer surface of the movable shaft 14, so that the paper bag 33 can be gradually released by the rotation of the movable shaft 14, so that the continuous operation of the paper bag 33 filter can be realized. The body 11 supports the guide roller 1 35 and the guide roller 2 37 for rotation respectively through the support rod 1 34 and the support rod 2 36. The guide roller 1 35 and the guide roller 2 37 are distributed up and down for tensioning and supporting the support net 38. The paper bag 33 is lifted and supported by the support net 38, and the gravity on the paper bag 33 can be shared at the same time, thereby reducing the probability of the paper bag 33 being damaged by the excessive gravity of the cutting fluid, and thus effectively improving the operating stability of the paper bag 33 filter.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the outer surface of the right end of the body 11 is fixedly connected to the box body 16, and the outer surface of the right end of the box body 16 is provided with a material trough 17. The outer surface of the rear end of the material trough 17 is fixedly connected to a fixed plate 25, and the outer surface of the upper end of the fixed plate 25 is fixedly connected to a motor 26. The front end of the output shaft of the motor 26 is fixedly connected to a winding roller 52, and the winding roller 52 is used to lift and recycle the paper bag 33. The paper bag 33 is in rotational contact with the lower side of the outer surface of the fixed cylinder 29. The paper bag 33 is located between the supporting net 38 and the fixed cylinder 29. The front side of the inner surface of the body 11 is fixedly connected to a liquid level meter 28.

[0043] The second connecting tube 30 and the rear side of the outer surface of the winding roller 52 are both fixedly connected with a synchronous wheel 23 , and the outer surface of the synchronous wheel 23 is rotatably connected with a synchronous belt 24 .

[0044] By adopting the above technical solution, the box 16 fixedly connected to the right end of the body 11 is used to store the waste paper bags 33. The box 16 is fixedly supported by the motor 26 through the fixing plate 25. When the paper bag 33 filter is working, when the impurities on the surface of the paper bag 33 are adsorbed too much, the permeability of the paper bag 33 will be significantly reduced, so the filtering capacity of the paper bag 33 will be reduced accordingly. Therefore, the cutting fluid level on the upper surface of the paper bag 33 will gradually rise, and the cutting fluid level is detected by the liquid level meter 28. When the cutting fluid level reaches a predetermined threshold, the liquid level meter 28 starts the motor 26 through the filter control system, and the output shaft of the motor 26 drives the winding roller 5. 2 rotates synchronously, and the paper bag 33 is rolled up by the winding roller 52. At the same time, the winding roller 52 can pull the paper bag 33. The paper bag 33 is located between the fixed cylinder 29 and the supporting net 38. The paper bag 33 is lifted and supported by the supporting net 38, so that the paper bag 33 can be closely attached to the outer surface of the fixed cylinder 29. The cutting fluid will continue to fall through the paper bag 33 and the supporting net 38 under the action of gravity, and the impurities mixed in the cutting fluid will remain on the upper surface of the paper bag 33. The cutting fluid can be effectively separated by the paper bag 33, so as to achieve filtering and purification of the cutting fluid. The connecting pipe 2 30 can lift and support the water inlet cylinder 31 and the fixed cylinder 29 by being rotatably connected to the machine body 11.

[0045] like Figure 4 and Figure 7As shown, a crushing assembly is provided on the inner side of the water inlet cylinder 31, and the crushing assembly includes a crushing block 1 42 fixedly connected to the inner surface of the water inlet cylinder 31, and a limiting plate 22 is fixedly connected to the outer surface of the rear end of the body 11, and the limiting plate 22 is an L-shaped structure. A fixing rod 44 is fixedly connected to the outer surface of the front end of the limiting plate 22, and the fixing rod 44 passes through the inner side of the water inlet cylinder 31 through the connecting pipe 2 30. A sealing sleeve 41 is fixedly connected to the inner surface of the connecting pipe 2 30, and the sealing sleeve 41 is rotatably connected to the fixing rod 44. A crushing block 2 43 is fixedly connected to the outer surface of the fixing rod 44, and the number of the crushing blocks 1 42 and 43 is several groups and distributed in a ring array.

[0046] By adopting the above technical scheme, the winding roller 52 will drive the synchronous wheel 23 on its surface to rotate synchronously during the rotation process, and the synchronous wheel 23 and the synchronous belt 24 will drive the connecting pipe 2 30 to rotate synchronously, and the connecting pipe 2 30 drives the water inlet cylinder 31 and the connecting pipe 1 27 to rotate synchronously, so that the crushing block 1 42 can be driven to rotate synchronously through the water inlet cylinder 31. The machine body 11 supports the fixed rod 44 through the limit plate 22, so that the crushing block 2 43 can be fixedly supported by the fixed rod 44. After the cutting fluid to be processed enters the water inlet cylinder 31, the large impurities in the cutting fluid are preliminarily crushed by the crushing blocks 1 42 and 2 43, so that the volume of the impurities can be reduced to a certain extent, so that the impurities can be better attached to the outer surface of the paper bag 33, so that the impurities can be better filtered and transported through the paper bag 33. The sealing sleeve 41 can seal between the fixed rod 44 and the connecting pipe 2 30, so as to prevent the cutting fluid from being discharged from the inside of the connecting pipe 2 30.

[0047] like Figure 5 , Figure 8 As shown, an extrusion assembly is provided on the inner side of the body 11, and the extrusion assembly includes a push rod 47 fixedly connected to the inner surface of the body 11. The outer surface of the fixed cylinder 29 is rotatably contacted with an extrusion roller 45, and a mounting hole 46 is opened on the inner side of the extrusion roller 45. The extrusion roller 45 is rotatably contacted with the push rod 47 through the mounting hole 46, and the diameter of the mounting hole 46 is larger than the diameter of the push rod 47.

[0048] By adopting the above technical solution, the machine body 11 fixes and supports the push rod 47, and the squeezing roller 45 is movably connected to the push rod 47 through the mounting hole 46. The squeezing roller 45 is in contact with the outer surface of the paper bag 33 under the action of gravity, so that the squeezing roller 45 cooperates with the guide roller 35 to squeeze the paper bag 33, thereby effectively reducing the residual cutting fluid in the paper bag 33, and further reducing the waste of coolant to a certain extent. The diameter of the mounting hole 46 on the inner side of the squeezing roller 45 is larger than the outer diameter of the push rod 47, so that the position of the squeezing roller 45 can be moved, so that the position of the squeezing roller 45 can be flexibly adjusted according to the distribution of impurities on the surface of the paper bag 33, thereby ensuring the squeezing effect of the cutting fluid in the paper bag 33.

[0049] like Figure 1 and Figure 5 As shown, a scraper assembly is provided on the inner side of the box body 16, and the scraper assembly includes a scraper 54 fixedly connected to the outer surface of the right end of the body 11, and a feed trough 56 is provided on the outer surface of the right end of the body 11. The paper bag 33 passes through the feed trough 56 to the inner side of the box body 16, and a traction bar 53 is fixedly connected to the outer surface of the upper end of the scraper 54. The upper end of the traction bar 53 is fixedly connected to the outer surface of the right end of the body 11, and the traction bar 53 is made of elastic material. The scraper 54 is in rotational contact with the outer surface of the paper bag 33.

[0050] By adopting the above technical scheme, the feeding trough 56 on the surface of the machine body 11 can facilitate the transportation of the paper bag 33 to the inside of the box body 16. The machine body 11 pulls and supports the scraper 54 through the traction bar 53. The scraper 54 keeps in close contact with the outer surface of the paper bag 33 under the elastic force of the traction bar 53. As the winding roller 52 rotates, the scraper 54 can scrape and clean the impurities adsorbed on the surface of the paper bag 33. The impurities fall into the storage box 12 under the action of gravity for centralized collection and treatment. As the number of paper bags 33 on the surface of the winding roller 52 continues to increase, the diameter of the cylinder formed by the paper bags 33 will gradually increase. At this time, the traction bar 53 gradually stretches downward. The scraper 54 will always keep in close contact with the outer surface of the paper bag 33 under the pulling force of the traction bar 53, so that the surface of the paper bag 33 can be continuously cleaned, so as to subsequently recycle the metal substances in the impurities. The material taking trough 17 on the surface of the box body 16 can facilitate the timely removal of the paper bag 33 on the surface of the winding roller 52.

[0051] Instructions for use: During operation, the guide roller 1 35 and the guide roller 2 37 are arranged up and down to tension and support the support net 38. The support net 38 is used to lift and support the paper bag 33 and share the gravity on the paper bag 33. The cutting fluid is injected into the rotary joint 19 through the liquid guide tube 20 under the action of gravity, and then injected into the water inlet cylinder 31 through the connecting pipe 1 27. The cutting fluid will fall downward through the through hole 32 on the surface of the water inlet cylinder 31 and contact with the top block 51 on the surface of the mounting shaft 50. The foam in the cutting fluid is crushed by the top block 51. The blade 40 on the inner side of the through groove 39 can not only have a certain buffering effect on the water flow, but also the tip of the blade 40 can have a secondary crushing and clearing effect on the remaining foam in the cutting fluid. The winding roller 52 winds up the paper bag 33, and the squeezing roller 45 contacts with the outer surface of the paper bag 33 under the action of gravity, so that the squeezing roller 45 cooperates with the guide roller 1 35 to squeeze the paper bag 33, so as to effectively reduce the residual cutting fluid in the paper bag 33, and the scraper 54 can scrape and clean the impurities adsorbed on the surface of the paper bag 33. The winding roller 52 drives the connecting pipe 2 30 to rotate through the synchronous wheel 23 and the synchronous belt 24, and the connecting pipe 2 30 drives the crushing block 1 42 to rotate synchronously through the water inlet cylinder 31, and the large impurities in the cutting fluid are preliminarily crushed by the crushing block 1 42 and the crushing block 2 43, so as to reduce the volume of the impurities to a certain extent, so that the impurities can be better adhered to and adsorbed on the outer surface of the paper bag 33.
