Description

Technical Field

[0001] The invention relates to the technical field of bioreactor processing, in particular to a bioreactor surface grinding dust recovery device. Background Art

[0002] In the manufacturing process of the bioreactor shell, grinding is mainly used to remove burrs, oxide layers, dirt, etc. on the shell surface to improve its surface finish, precision and corrosion resistance. Through grinding, a smoother and more uniform surface can be obtained, which is conducive to the cleaning and disinfection of the inside of the bioreactor, and also helps to improve the overall performance and life of the equipment.

[0003] After searching, the Chinese patent with the announcement number CN202751895U discloses a dry dust collector for casting and grinding iron powder, which is characterized by comprising a dust box, the lower end of the dust box is an air inlet box, the air inlet box is connected to the air inlet pipe, a dust baffle is arranged between the air inlet box and the dust box, and a plurality of dust air inlets are arranged on the dust baffle, each dust air inlet is provided with a dust bag, a hook is arranged above the dust bag, the hook is hung on a vibrating suspension plate, the upper part of the suspension plate is an induced draft box, and the induced draft box is connected to the induced draft fan through the induced draft pipe; it also includes a pulse recoil dust removal device, the recoil dust removal device is fixedly mounted at the lower end of the dust baffle and corresponds to each dust air inlet. The above scheme improves the working environment of the staff and protects the health of the staff. On the other hand, it improves the surrounding environment so that the air discharged to the outside meets the emission standards. However, the above scheme still has the following shortcomings when it is actually used: The dust removal device proposed in the above scheme uses pulse back-blowing to clean the filter element. However, in actual application, the dust attached to the surface of the filter element cannot be completely removed by pulse back-blowing alone. First, the material characteristics of the filter bag have a significant impact on the cleaning effect. The surface of the filter bag of some materials is rough. Such a surface structure is easy to accumulate dust, and the jet back-blowing method is difficult to effectively remove these stubborn dusts. The rough surface increases the adhesion area and adhesion of the dust particles, making it difficult for the pulse back-blowing airflow to peel them off. Secondly, environmental factors are also important factors affecting the pulse cleaning effect. Excessive humidity will cause the dust to easily absorb moisture and agglomerate to form larger dust clumps. These clumps are not only difficult to be blown away by the pulse airflow, but may also form a relatively firm adhesion layer on the surface of the filter bag, further increasing the difficulty of cleaning. In addition, excessively high temperature will also make the adsorption force of dust stronger. In a high temperature environment, the activity of dust particles is enhanced, and it is easier to physically or chemically adsorb with the surface of the filter bag to form a tight adhesion layer. This tight adhesion layer is not only difficult to be blown off by the pulse airflow, but may also cause damage to the surface of the filter bag, affecting its service life.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-13A bioreactor surface grinding dust recovery device comprises a mobile base 1, an outer hood 11 and an air suction fan 12 are arranged on the mobile base 1, an air inlet end of the air suction fan 12 is connected to a dust hood 13 through an air inlet pipe, and an air outlet end of the air suction fan 12 is connected to a dust exhaust pipe 14, and the dust exhaust pipe 14 extends to the inside of the outer hood 11. When the bioreactor surface grinding dust recovery device proposed by the present invention is used, the staff pushes the mobile base 1 to the periphery of the bioreactor surface grinding device, adjusts the inside of the air suction hood, and makes the air suction hood Facing the grinding parts in the grinding device, when the grinding device is grinding the surface of the bioreactor, the staff starts the suction fan 12. When the suction fan 12 is running, the dust generated in the grinding process is absorbed through the suction hood, and the dust is discharged into the interior of the outer cover 11 to capture and collect the dust. In addition, a pulse back-blowing cleaning system is arranged inside the outer cover 11. The specific structure and working principle of the pulse back-blowing cleaning system are the existing technology, and the implementation method adopts conventional means, which is not shown in the figure and will not be described in detail here. like Figure 7 and Fig.11 As shown, a flow equalizing component is arranged inside the outer hood 11, and the flow equalizing component is arranged opposite to the dust exhaust pipe 14 for equalizing the airflow; the flow equalizing component includes an air guide cover 21, a plurality of guide plates 22 and a flow equalizing plate 23, the air guide cover 21 is fixed inside the outer hood 11, the air guide cover 21 is connected to the air outlet end of the air suction fan 12, the air guide cover 21 is a funnel-shaped structure, each guide plate 22 is fixed inside the air guide cover 21, the flow equalizing plate 23 is fixed at one end of the air guide cover 21 away from the air suction fan 12, and a plurality of openings 24 are opened on the flow equalizing plate 23; like Fig. 9 As shown, a dust collection unit is arranged inside the outer hood 11, and the dust collection unit includes a bracket assembly and two dust filter assemblies. The bracket assembly includes an upper mounting frame 31 and a lower mounting frame 32, and the upper mounting frame 31 and the lower mounting frame 32 are connected by a partition plate 33. The dust filter assembly includes a filter element 34, and the filter element 34 is arranged between the upper mounting frame 31 and the lower mounting frame 32. The dust filter assembly also includes a fixed pipe 35 and an exhaust pipe 36. The fixed pipe 35 is fixed to the top of the filter element 34, and the fixed pipe 35 is rotatably assembled on the upper mounting frame 31. The exhaust pipe 36 is fixed inside the fixed pipe 35, and one end of the exhaust pipe 36 is connected to the inside of the filter element 34, and the other end extends to the outside of the fixed pipe 35. A dust collecting seat is arranged inside the outer hood 11, and the dust collecting seat is located directly below the lower mounting frame 32. For the outer hood 11, two filter elements 34 are arranged inside, one of which is facing the air guide cover 21. When the dust-laden airflow is discharged by the suction fan 12, the dust-laden airflow will first enter the air guide cover 21. In this process, the flow equalization component first plays a role. The flow equalization component consists of the air guide cover 21, a plurality of guide plates 22 and a flow equalization plate 23. The air guide cover 21 is fixed inside the outer hood 11 and is connected to the dust exhaust pipe 14. The design of the air guide cover 21 is a funnel-shaped structure. This design helps to The airflow from the air intake fan 12 is initially guided and concentrated. A plurality of guide plates 22 are fixed inside the air guide cover 21. The function of these guide plates 22 is to further guide and disperse the airflow entering the air guide cover 21, ensuring that the airflow can be evenly distributed in the internal space of the air guide cover 21. By adjusting the guide plates 22, the airflow can reduce eddy currents and turbulence during the flow process, thereby improving the stability and uniformity of the airflow. Finally, the equalizer plate 23 is fixed to the air guide cover 21 away from the air intake fan 12. At one end of the filter element 34, a plurality of openings 24 are provided on the flow equalizer plate 23. The design of these openings 24 enables the airflow guided by the guide plate 22 to flow out evenly through these openings 24, further realizing the equalization of the airflow. The existence of the flow equalizer plate 23 ensures that the airflow discharged from the suction fan 12 can flow toward the filter element 34 facing the air guide cover 21 in a more uniform and stable state after passing through the flow equalizer component. In the height direction of the filter element 34, the guide cover covers the entire filter element 34, which enables the dust-laden airflow to flow evenly toward the filter element 34 under the action of the flow equalizer component, and the dust will be evenly attached to the surface of the filter element 34, thereby improving the utilization efficiency of the filter element 34. Because the dust distribution is more even, each part of the filter element 34 can give full play to its filtering effect. Secondly, this uniform attachment reduces the risk of premature clogging of the filter element 34 due to local overload, thereby extending the service life of the filter element 34. In addition, the uniform dust distribution also helps to maintain the stable operation of the system, and reduces the performance degradation and failure rate caused by clogging of the filter element 34. In addition, when starting the suction fan 12, the staff starts the driving motor 41 synchronously, so that the driving motor 41 drives the first gear 42 to rotate. When the first gear 42 rotates, it can drive the first gear ring 44 to rotate. When the first gear ring 44 rotates, it can drive the two second gears 45 to rotate, which makes the two fixed pipes 35 rotate, and the filter element 34 connected to the fixed pipe 35 will also rotate accordingly. Based on the above process, when the driving motor 41 is running, through the power transmission of the first gear 42, the first gear ring 44 and the two second gears 45, the two filter elements 34 can slowly rotate. The self-rotation action of the filter element 34 cooperates with the flow balancing effect of the flow balancing component, so that the dust-laden airflow can be more evenly covered at every part of the filter element 34, further improving the dust capture effect of the filter element 34, avoiding the local blockage of the filter element 34, and ensuring the stable operation of the device. like Figure 6, Fig. 9 and Fig.10 As shown, a rotating assembly is provided on the upper mounting frame 31, and a cleaning assembly is provided on the lower mounting frame 32. The cleaning assembly consists of two cleaning parts and a second gear ring 55. The second gear ring 55 is fixed to the inside of the outer hood 11 through two connecting blocks. Each cleaning part includes a lifting structure and a cleaning structure. When the lifting assembly is in operation, the cleaning structure moves along the filter element 34 to brush off the dust on the surface of the filter element 34. The rotating assembly includes a driving motor 41, a first gear 42, a rotating seat 43, a first gear ring 44 and two second gears 45. The driving motor 41 is installed on the upper mounting frame 31 through a motor frame. The first gear 42 is fixedly sleeved on the output shaft of the driving motor 41. The rotating seat 43 is rotatably installed on the top surface of the upper mounting frame 31. The first gear ring 44 is fixed to the inner ring of the rotating seat 43. The two second gears 45 are fixedly sleeved on the two fixed tubes 35 respectively. The first gear 42 and the two second gears 45 are meshed with the first gear ring 44. The lifting structure includes a screw rod 51, a guide rod 52 and two moving blocks 53. The screw rod 51 is rotatably assembled between the upper mounting frame 31 and the lower mounting frame 32. The guide rod 52 is fixed between the upper mounting frame 31 and the lower mounting frame 32. One of the moving blocks 53 is threadedly sleeved on the screw rod 51, and the other moving block 53 is slidably sleeved on the guide rod 52. The bottom end of the screw rod 51 is fixedly sleeved with a third gear 54, and the third gear 54 and the second gear ring 55 are meshed with each other; the cleaning structure includes a fixed ring 56 and a cleaning ring 57. The fixed ring 56 is fixed between the two relatively arranged moving blocks 53. The cleaning ring 57 is rotatably assembled on the inner ring of the fixed ring 56. The cleaning ring 57 is sleeved on the filter element 34, and the inner ring of the cleaning ring 57 is arranged with bristles 58. like Figure 2-4 As shown, a top cover is fixed on the top of the outer hood 11, and a flip assembly is arranged inside the top cover. The flip assembly is used to drive the upper mounting frame 31 and the lower mounting frame 32 to rotate. The flip assembly includes a shaft 61, a cylinder 62, a rack 63 and a fourth gear 64. The shaft 61 passes through the top surface of the outer hood 11 and is rotatably connected to the outer hood 11. The bottom end of the shaft 61 is fixedly connected to the upper mounting frame 31. The cylinder 62 is installed on the top surface of the outer hood 11. The fourth gear 64 is fixedly sleeved on one end of the shaft 61 located outside the outer hood 11. The rack 63 is meshed with the fourth gear 64. A side plate 65 is fixed at the end position of the rack 63, and the side plate 65 is fixedly connected to the telescopic end of the cylinder 62. The dust recovery device proposed in the present invention has the function of automatically cleaning the filter element 34. On the basis of the traditional pulse back-blowing cleaning, the present invention adopts a brush cleaning method to clean the filter element 34. Specifically, when the filter element 34 needs to be cleaned, the staff starts the cylinder 62. When the telescopic end of the cylinder 62 is extended, it can drive the rack 63 to move through the side plate 65, so that the rack 63 drives the fourth gear 64 to rotate. When the fourth gear 64 rotates, it will drive the shaft rod 61 to rotate, and the upper mounting frame 31 connected to the shaft rod 61 will rotate accordingly. In this process, the upper mounting frame 31 arranged at The two filter elements 34 between the upper mounting frame 31 and the lower mounting frame 32 will also rotate synchronously. During the rotation of the upper mounting frame 31 and the lower mounting frame 32, the two third gears 54 will rotate around the center position of the second gear ring 55 and rotate under the meshing action of the second gear 45, which makes the two screw rods 51 rotate. Under the cooperation of the two third gears 54 and the second gear ring 55, the two screw rods 51 can also rotate while following the rotation of the upper mounting frame 31 and the lower mounting frame 32. For the screw rod 51, the screw rod 51 The self-rotation action cooperates with the limiting effect of the guide rod 52 to drive the two moving blocks 53 to move from top to bottom. When the two moving blocks 53 move, the fixed ring 56 and the cleaning ring 57 move accordingly. In this process, the bristles 58 on the inner ring of the cleaning ring 57 will continuously brush the surface of the filter element 34, and can remove the dust attached to the surface of the filter element 34. At the same time, in conjunction with the pulse back-blowing cleaning system (proposed as a prior art, not shown in the figure), the cleaning effect of the filter element 34 can be improved. This new cleaning method combining mechanical brushing and pulse back-blowing brings significant Advantages: First, mechanical brushing can directly act on the surface of the filter element 34, more effectively removing the dust stubbornly attached or embedded in the pores of the filter element 34, and improving the thoroughness of dust cleaning. Second, the continuous brushing of the bristles 58 helps to loosen the dust layer on the surface of the filter element 34, so that the subsequent pulse backwashing can blow the dust off the filter element 34 more smoothly, thereby enhancing the dust cleaning efficiency. This combined cleaning method can extend the service life of the filter element 34, because more thorough dust cleaning reduces the risk of clogging and performance degradation of the filter element 34 due to long-term accumulation of dust; Furthermore, when the cylinder 62 completes the entire moving stroke, the rack 63 just drives the fourth gear 64 to rotate 180°, which causes the two filter elements 34 to rotate 180° as well. In this case, the positions of the two filter elements 34 will be swapped, and the filter element 34 that was originally in working state and has accumulated a certain amount of dust will be rotated to a position away from the air guide cover 21, while the new, unused filter element 34 will be rotated to a position facing the air guide cover 21, ready to undertake the next dust filtering task. Through this innovative design, the staff can replace the old filter element 34 without stopping the equipment. This design improves the operating efficiency and continuity of the equipment, because the process of replacing the filter element 34 does not need to interrupt the operation of the entire system, and the timely activation of the new filter element 34 can ensure the dust capture effect, which helps to keep the device in an efficient dust filtering state at all times. like Fig.12 and Fig.13 As shown, a plurality of axial flow blades 59 are fixed to the outer circumferential surface of the cleaning ring 57, and the plurality of axial flow blades 59 are distributed in a circumferential array. A connecting frame 77 is fixed to the side of one of the moving blocks 53, and an air jet 78 is fixed to the end of the connecting frame 77 away from the moving block 53, and the air jet 78 is arranged directly opposite to one of the axial flow blades 59. An air supply assembly is arranged at the top of the outer hood 11, and the air supply assembly includes an air suction cylinder 71, a rotating shaft 73 and an air suction member 76. The air suction cylinder 71 is fixed inside the top hood, and a plurality of air inlets 72 are opened on the air suction cylinder 71. The rotating shaft 73 passes through the bottom surface of the air suction cylinder 71 and is rotatably connected to the air suction cylinder 71. The rotating shaft 73 passes through the bottom surface of the air suction cylinder 71 and is rotatably connected to the air suction cylinder 71. One end located inside the air suction cylinder 71 is fixedly connected to the air suction member 76. The air suction member 76 includes a sleeve and a plurality of blades. The sleeve is fixedly sleeved on the rotating shaft 73. Each blade is fixed on the outer peripheral surface of the outer cylinder. The plurality of blades are distributed in a circumferential array. One end of the rotating shaft 73 located outside the air suction cylinder 71 is rotatably assembled on the top surface of the outer hood 11. A fifth gear 74 is fixedly sleeved on the rotating shaft 73. A sixth gear 75 meshing with the fifth gear 74 is arranged on one side of the fifth gear 74. The sixth gear 75 is fixedly sleeved on one end of the shaft 61 located outside the outer hood 11. An air supply pipe is connected to the air suction cylinder 71. Each jet pipe 78 is connected to the air supply pipe. In the present invention, an air supply assembly is also introduced to drive the cleaning ring 57 in a moving state to rotate. Specifically, in the process of the rack 63 driving the fourth gear 64 to rotate, the shaft 61 can drive the rotating shaft 73 to rotate through the fifth gear 74 and the sixth gear 75 that are meshed with each other, and the suction member 76 connected to the rotating shaft 73 rotates accordingly. When the suction member 76 rotates, several fan blades therein can perform a suction action and introduce the gas into the suction cylinder 71 through the air inlet 72. Further, under the rotation of the suction member 76, the gas will be discharged through the air supply pipe and finally ejected through the two injection pipes 78. For the cleaning ring 57, there are several fixed thereon. The dry axial flow blades 59, and the jet pipe 78 is just set opposite to one of the axial flow blades 59, so the gas ejected from the jet pipe 78 can blow several axial flow blades 59 to rotate, so that the cleaning ring 57 rotates. Based on the above process, under the jet action of the jet pipe 78, the cleaning efficiency of the filter element 34 is significantly improved, because the bristles 58 can more comprehensively cover the surface of the filter element 34 under the dual effects of movement and rotation, ensuring that the dust on the surface of the filter element 34 is more thoroughly removed. It is worth mentioning that the air supply pipe and the jet pipe 78 are connected by a hose, and the variability of the hose allows the jet pipe 78 to smoothly rotate with the upper mounting frame 31.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
