Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-11The embodiments of the present invention will be described in detail.

[0026] A dust removal device for a dry-mixed mortar production system includes a dust removal box 1. The dust removal box 1 is equipped with two partitions 2, which divide the interior of the dust removal box 1 into a dust removal chamber 3, a drying chamber 4, and a cleaning chamber 5. The dust removal chamber 3, the drying chamber 4, and the cleaning chamber 5 are arranged sequentially from top to bottom. The dust removal chamber 3 is equipped with several filter plates 6. The left and right ends of the dust removal chamber 3 are respectively connected to a suction pipe 11 and an exhaust pipe 13. A negative pressure fan 12 is installed at the lower part of the suction pipe 11. The drying chamber 4 is connected to an air inlet pipe 14 and an air outlet pipe 26 on its left and right sides, respectively. An exhaust fan 16 is installed on the air inlet pipe 14, and a filter screen 15 is installed at the inlet of the air inlet pipe 14. A notch 51 is provided on the partition plate 2 below the filter plate 6. A lifting mechanism 64 capable of moving the filter plate 6 up and down is installed on the upper part of the dust collector 1. A rotating seat 17 is installed on the right side of the dust collector 1, and a rotating shaft 18 is rotatably mounted on the rotating seat 17. The upper end of the rotating shaft 18 extends into the exhaust pipe 13 and is connected to a fan wheel 19. A drive bevel gear 21 is installed on the dust collector 1. A drive bevel gear 22 is connected to the lower end of the rotating shaft 18. A rotating sleeve 86 is installed on the dust collector 1 corresponding to the position of the drying chamber 4. A rotating shaft 23 is rotatably installed inside the rotating sleeve 86. The left end of the rotating shaft 23 is located inside the drying chamber 4 and is connected to several fan blades 24. The right end of the rotating shaft 23 is connected to a driven bevel gear 25. The drive bevel gear 21 can mesh with the driven bevel gear 25. A rotating frame 37 is installed inside the air outlet pipe 26. A rotating frame 37 is rotatably installed inside the rotating frame 37. There is a rotating shaft 38, with several fan blades 39 on the left side of the rotating shaft 38. A driven pulley 40 is connected to the right end of the rotating shaft 38. A rotating frame 31 is installed on the upper part of the air outlet pipe 26. A rotating shaft 32 is rotatably installed inside the rotating frame 31. A driving pulley 33 and a driven bevel gear 24 are respectively connected to the left and right ends of the rotating shaft 32. The driven bevel gear 24 can mesh with the driving bevel gear 22. A transmission belt 41 is connected between the driven pulley 40 and the driving pulley 33. A hydraulic cylinder 30 is installed on the right side of the dust collector box 1. The piston rod of the hydraulic cylinder 30 is connected to a support arm 28 at its lower end. The right end of the support arm 28 is connected to two clamping blocks 29. A rotating shaft 18 passes through the clamping blocks 29. A tray 27 is located on the rotating shaft 18 between the two clamping blocks 29. A thrust ball bearing is located between the tray 27 and the clamping blocks 29. A valve plate 36 is inserted into the air outlet pipe 26. A connecting arm 35 is connected to the lower end of the valve plate 36. The upper end of the connecting arm 35 is connected to the support arm 28. A heating tube 84 is located to the left of the fan blade 24 in the drying chamber 4.

[0027] The lifting mechanism 64 moves the filter plate 6 up and down in the dust collection box 1, positioning it in the dust collection chamber 3, drying chamber 4, or cleaning chamber 5. The filter plate 6 can be cleaned and dried within the dust collection box 1 without needing to remove it from the dust collection box 1 for maintenance after stopping the machine.

[0028] The dust suction pipe 11 is connected to various mechanisms in the dry-mixed mortar production system. Under the action of the negative pressure fan 12, it sucks in the dust generated by each mechanism during the production process. When the dust-laden air flows through the dust removal chamber 3, it is facilitated by the filter plate 6 to filter the dust. The filtered air is then blown out through the exhaust pipe 13.

[0029] When air flows through the exhaust pipe 13, it drives the impeller 19 to rotate, which in turn drives the rotating shaft 18 to rotate. By adjusting the height of the rotating shaft 18, when the driving bevel gear 21 meshes with the driven bevel gear 25, the rotating shaft 18 can drive the rotating shaft 23 to rotate through the engagement of the driving bevel gear 21 and the driven bevel gear 25, thereby driving the fan blade 24 to rotate. The fan blade 24 blows the air heated by the heating tube 84, allowing the hot air to circulate in the drying chamber 4, so that the filter plate 6 located in the drying chamber 4 can be evenly heated and dried. At the same time, when the support arm 28 adjusts the height of the rotating shaft 18 so that the driving bevel gear 21 and the driven bevel gear 25 mesh, the connecting arm 35 drives the valve plate 36 to be inserted into the air outlet pipe 26, thus sealing the air outlet pipe 26 and keeping the drying chamber 4 in a relatively sealed state, so that the hot air in the drying chamber 4 will not escape and the heat in the drying chamber 4 will be maintained.

[0030] After drying is complete, the drying chamber 4 needs to return to normal temperature, which requires the hot air to be discharged. Hydraulic cylinder 30 controls the extension of its piston rod, causing support arm 28 to move downwards. Support arm 28 drives rotating shaft 18 to descend, causing drive bevel gear 21 to disengage from driven bevel gear 25 and drive bevel gear 22 to mesh with driven bevel gear 24. Simultaneously, connecting arm 35 drives valve plate 36 downwards, connecting air outlet duct 26 to the interior of drying chamber 4. Rotating shaft 18, through the engagement of drive bevel gear 22 and driven bevel gear 24, drives drive pulley 33 on rotating shaft 32 to rotate. Drive pulley 33 then drives driven pulley 40 to rotate via transmission belt 41. Driven pulley 40 drives fan blade 39 on rotating shaft 48 to rotate, thereby extracting the hot air from drying chamber 4. External air is then sent into drying chamber 4 through air inlet duct 14 by exhaust fan 16, lowering the temperature inside drying chamber 4 to room temperature and cooling the dried filter plate 6.

[0031] Preferably, the filter plate 6 includes a mounting frame 7, in which filter cotton 8 is provided. Both sides of the upper end and both sides of the lower end of the mounting frame 7 are provided with abutting slopes 9. Movable grooves 52 are provided on both sides of the notch 51 on the partition plate 2. Movable blocks 53 are provided in the movable grooves 52. A second spring 54 is connected between the outer end of the movable block 53 and the side wall of the movable groove 52. The upper and lower parts of the inner end of the movable block 53 are provided with mating slopes 55 that cooperate with the abutting slopes 9. Under the action of the second spring 54, the movable block 53 can abut against the mounting frame 7, so that the mating slopes 55 and the abutting slopes 9 are in contact, thereby achieving a certain sealing effect and preventing the air between the dust removal chamber 3 and the drying chamber 4 from circulating between them.

[0032] Preferably, the lifting mechanism includes a rotating frame 74 located above the dust collector 1. A guide wheel 75 is rotatably mounted on the left side of the rotating frame 74, and a rotating shaft 76 is rotatably mounted on the right side. A winding wheel 79 and a driven gear 77 are mounted on the rotating shaft 76. A through hole 49 is provided on the dust collector 1 corresponding to the position below the guide wheel 75. A connecting rope 50 is wound around the winding wheel 79. The other end of the connecting rope 50 passes around the guide wheel 75, through the through hole 49, and connects to the upper end of the filter plate 6. A drive motor 72 is mounted on the dust collector 1, and the drive motor 72 drives a drive gear 73. The drive gear 73 can mesh with the driven gear 77. By rotating the drive motor 72 forward and backward, the drive gear 73 drives the driven gear 77 to rotate, thereby causing the winding wheel 79 on the rotating shaft 76 to rotate forward and backward, thus winding and unwinding the connecting rope 50, and consequently raising and lowering the filter plate 6.

[0033] Preferably, a cleaning sleeve 80 is provided on the upper part of the rotating frame 3 74, and the connecting rope 50 passes through the cleaning sleeve 80. The cleaning sleeve 80 cleans the connecting rope 50, removes impurities attached to the connecting rope 50, and prevents impurities from contaminating the whole when the connecting rope 50 is wound, thereby preventing the connecting ropes 50 from sticking together.

[0034] Preferably, the dust collector 1 is equipped with a movable frame 85, and mounting plates 69 are provided on the movable frame 85 at positions corresponding to the lifting mechanisms 64. A drive motor 72 is mounted on the front side of the upper part of the mounting plate 69. A limit gear 78 is connected to the rear end of the rotating shaft 76. A fixed arm 70 is provided on the rear side of the upper part of the mounting plate 69, and a locking pin 71 that cooperates with the limit gear 78 is installed on the fixed arm 70. A lead screw seat 66 is provided on the dust collector 1, and a lead screw 67 is rotatably mounted on the lead screw seat 66. A lead screw motor 68 is located on the rear side of the lead screw seat 66, driving the lead screw 67. A lead screw slider 65 is provided on the lead screw 67, and the lead screw slider 65 is connected to the side of the movable frame 85. The lead screw 67 is driven to rotate by the lead screw motor 68, and then the movable frame 85 is moved by the lead screw slider 65, thereby adjusting the position of each mounting plate 69. When the mounting plate 69 moves backward, the drive gear 73 meshes with the driven gear 77, and the locking pin 71 disengages from the limiting gear 78, thereby releasing the restriction on the position of the winding wheel 79. At this time, the drive gear 73 can drive the winding wheel 79, which is coaxial with the driven gear 77, to rotate, thereby winding and unwinding the connecting rope 50. This adjusts the height of the filter plate 6, allowing it to enter the dust removal chamber 3, the drying chamber 4, or the cleaning chamber 5 for corresponding filtration, drying, and cleaning operations.

[0035] When the mounting plate 69 moves forward, the locking pin 71 engages with the teeth of the limiting gear 78, and the driving gear 73 disengages from the driven gear 77, thereby limiting the position of the winding wheel 79 and fixing the position of the filter plate 6 in the dust collector 1, thus reducing the working pressure of the drive motor 72.

[0036] Preferably, two adjacent mounting plates 69 are staggered, that is, the first mounting plate 69 and the second mounting plate 69 are offset from each other, while the first mounting plate 69 and the third mounting plate 69 are in the same position. This allows half of the filter plates 6 to be in the filtering working state, while the other half of the filter plates 6 are in the cleaning and drying state. Each filter plate 6 operates in a cycle, which can maintain a good filtering effect for each filter plate 6 and enable the device to achieve continuous dust removal without the need for downtime maintenance.

[0037] Preferably, the bottom of the cleaning chamber 5 is provided with several vibrators 81, and the cleaning chamber 5 is provided with a stirring motor 82, which drives the stirring blades 83.

[0038] Preferably, the bottom of the cleaning chamber 5, located below the filter plate 6, has an insertion groove 56. The bottom of the insertion groove 56 has a receiving groove 57. The lower part of the receiving groove 57 has an annular groove 59 and a mounting groove 58. The mounting groove 58 is located inside the annular groove 59 and contains a trigger 60. A trigger block 61 is positioned above the receiving groove 57. A spring 62 connects the bottom of the trigger block 61 to the bottom of the mounting groove 58. A bellows 63 is connected to the bottom of the trigger block 61, and the lower end of the bellows 63 is connected to the bottom of the annular groove 59. The system also includes a controller, which is electrically connected to the trigger 60, the vibrator 81, and the stirring motor 82.

[0039] When filter plate 6 descends into cleaning chamber 5, its lower end inserts into placement groove 56. Filter plate 6 presses trigger block 61 into receiving groove 57, causing trigger block 61 to contact trigger 60. Trigger 60 sends a signal to controller, causing controller to operate vibrator 81 and stirring motor 82, thereby causing the cleaning fluid in cleaning chamber 5 to flow, rinsing filter plate 6 in cleaning chamber 5, removing impurities attached to filter plate 6, and restoring filter plate 6 to its original filtration effect.

[0040] The corrugated pipe 63 encloses the component internally, which can provide a waterproof effect and enable the component to function normally.

[0041] Preferably, the top of the dust removal chamber 3 is provided with a groove 47 and a limiting groove 48 above the filter plate 6. When the filter plate 6 is in the dust removal chamber 3, the upper end of the filter plate 6 can extend into the groove 47, and the sleeve 10 can be inserted into the limiting groove 48, thereby playing a role in positioning the filter plate 6.

[0042] Preferably, a detection tube 20 is provided inside the exhaust pipe 13. The inner diameter of the left end of the detection tube 20 is larger than that of the right end. A mounting bracket 42 is provided on the inner side of the right end of the detection tube 20. A spring 43 is connected to the left side of the mounting bracket 42. A baffle 44 is connected to the left end of the spring 43. A trigger 46 is provided in the middle of the left side of the mounting bracket 42. A trigger block 45 is provided on the side of the baffle 44 facing the mounting bracket 42. The trigger 46 is electrically connected to the controller. The controller is electrically connected to the lifting mechanism.

[0043] The inner diameter of the detection tube 20 is smaller than that of the exhaust pipe 13, and the inner diameter of the left end of the detection tube 20 is larger than that of the right end. This results in a faster airflow velocity when the air passes through the right side of the inner side of the detection tube 20, which allows the baffle 44 to press against the trigger 46. After the filter plate 6 has been used for a period of time, impurities will accumulate on its surface, affecting its filtration effect and reducing airflow. At this time, the airflow velocity through the detection tube 20 slows down, and the baffle 44 will move away from the trigger 46 under the action of the spring 43, thereby sending a signal to the lifting mechanism. This causes the lifting mechanism to lower the filter plate 6 for cleaning and drying.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
