Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a dust removal machine for the production of powdered water-soluble fertilizer. Background Technology

[0002] The production process of powdered water-soluble fertilizer will generate irritating gases. These gases need to be treated before they can be safely discharged into the external environment. In addition, these gases will also be mixed with some water-soluble fertilizer powder during the production process, so dust removal treatment is required.

[0003] The existing authorized patent with publication number CN222036256U discloses a dust removal device for a water-soluble fertilizer workshop. This device includes: "a fixed frame, a dust removal component mounted on the upper part of the fixed frame, and a suction component mounted on the outside of the fixed frame corresponding to the position of the dust removal component; the dust removal component includes a dust removal box mounted on the top of the fixed frame, a box cover mounted on the upper part of the dust removal box, a suction box mounted in the middle of the top of the box cover, a suction motor fixedly mounted on the top of the suction box, a fan wheel rotatably connected inside the suction box, and the input shaft of the fan wheel connected to the output shaft of the suction motor; an air inlet pipe fixedly mounted outside the dust removal box; and a dust scraping mechanism provided at the bottom of the box cover." This achieves the goal that "when the suction motor drives the fan wheel to rotate, it can drive the rotating shaft to rotate synchronously. Through the cooperation of planetary gears and a gear ring, it drives the three-link frame to rotate at a reduced speed. The connecting shaft can then drive the connecting frame to rotate, and the scraper can scrape away the dust on the inner wall of the dust removal box, thereby improving the cleaning effect and convenience, and is better than traditional methods."

[0004] However, in actual use, the above-mentioned device only uses the vacuum motor to remove dust from the exhaust gas. When the vacuum motor is running at high speed, a "penetration phenomenon" is likely to occur. That is, tiny particles that are not effectively captured directly pass through the filter medium and enter the clean air side. When the airflow speed exceeds the critical value, the dust-carrying particles cannot follow streamline motion due to excessive momentum. Instead, they bounce through the filter material surface along a straight trajectory. Therefore, it is impossible to completely separate the dust mixed in the exhaust gas.

[0005] This application proposes a dust collector for the production of powdered water-soluble fertilizers to solve the above-mentioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a dust collector for the production of powdered water-soluble fertilizers, thereby solving the problems mentioned in the background section.

[0014] Preferably, the fixed ring is slidably connected to the inside of the vertical groove by a slider, and the number of fixed rings is the same as the number of filter plates.

[0015] Preferably, it also includes auxiliary components disposed inside the housing of the dust removal device;

[0016] The auxiliary component includes a driven shaft fixedly connected to the center of the bottom surface of the planetary gear. Multiple positioning rings are fixedly connected at equal intervals along the vertical direction on the outer surface of the driven shaft. Multiple limiting rods are fixedly connected in a circumferential array on the outer surface of the positioning rings.

[0017] Preferably, each positioning ring is disposed below the corresponding filter plate, the vertical height of the two positioning rings located below the same filter plate decreases along the inclined direction of the filter plate, and the two positioning rings are respectively located on the outer surface of the two driven rotating shafts.

[0018] Preferably, the inner walls on both sides of the limiting crossbar are provided with through grooves, and the two ends of the driven member are fixedly connected with sliding cylinders. The sliding cylinders are slidably connected in the through grooves, and a restoring spring is fixedly connected between the sliding cylinders and the groove wall. The end of the driven member away from the limiting crossbar is set to an ellipse.

[0019] Compared with the prior art, the present invention provides a dust collector for the production of powdered water-soluble fertilizers, which has the following beneficial effects:

[0020] By using multiple inclined filter plates, the dust mixed in the exhaust gas is separated, thereby purifying the exhaust gas generated during the production of powdered water-soluble fertilizer. The inclined structure makes the airflow direction form an angle with gravity, increasing the probability that the particles will fall naturally due to their own weight. In addition, the design of multiple filter plates can achieve multi-stage interception. Large particles are first captured by the high-level coarse filter plate, while fine dust is further removed by passing through subsequent precision plates.

[0021] During the process of filtering exhaust gas, the filter plate will reciprocate vertically under the action of the fixed ring and wedge. When the filter plate reciprocates up and down, the dust particles attached to its surface are peeled off due to inertia, thus effectively avoiding the problem of increased wind resistance caused by mesh blockage. Moreover, the reciprocating motion of the filter plate will periodically change the local pressure difference, causing the gas to penetrate the filter material in a pulse form. This unsteady flow mode can break the boundary layer effect, making it easier for small particles to be captured. In the scenario of multi-layer stacked arrangement, the movement of filter plates at different heights can build a dynamic filtration gradient. After the lower layer coarsely filters large particles, the upper layer precision filter screen processes fine dust, forming a cascade purification effect.

[0022] By setting up a limiting link, connecting rod, limiting crossbar and driven component, when the limiting link, connecting rod, limiting crossbar and driven component rotate with the driven rotating shaft, they rotate in the opposite direction to the agitator fan that rotates under the action of the output rotating shaft, agitating the exhaust gas. The reverse airflow generated by the reverse rotation will continuously peel off the dust captured on the filter screen, avoiding blockage at the bottom of the filter plate.

[0023] Among them, the setting of the limiting link, connecting rod, limiting crossbar and driven part can scrape the bottom surface of the filter plate when in contact with the bottom surface of the filter plate. The tangential force generated by the scraping action can directly destroy the adhesion between dust and the surface of the filter material, avoid the air volume reduction caused by the thickening of dust accumulation, and the combination of physical scraping and the vibration of the filter plate itself can further prevent the filter plate from becoming blocked.

[0024] The rotational connection between the limiting crossbar, connecting rod and limiting link ensures that the driven part is in a deformed state after contacting the filter plate, so that the driven part is stably attached to the lower surface of the inclined filter plate. In addition, the driven part will undergo a state change as it moves with the filter plate, so that the driven part itself is in a moving state, thereby avoiding dust remaining on the surface of the driven part after dust is scraped off, which would affect the next cleaning of the filter plate by the driven part.

[0025] The arrangement of the drive gear and planetary gears ensures that the rotational speed of the driven component on the driven shaft is greater than the rotational speed of the agitator fan on the output shaft. The higher rotational speed of the driven component compared to the agitator fan speeds up the airflow after it passes through the filter plates. This prevents the exhaust gas from being blocked by the filter plates after passing through multiple filter plates, thus avoiding the accumulation of exhaust gas inside the dust removal device housing.

[0053] Further embodiments

[0054] Please see Figure 5 , Figure 6 , Figure 8 and Figure 9 The dust collector for powder water-soluble fertilizer production also includes auxiliary components installed inside the dust collector housing 11;

[0055] The auxiliary components include a driven shaft 41 fixedly connected to the center of the bottom surface of the planetary gear 25. Multiple positioning rings 42 are fixedly connected at equal intervals along the vertical direction on the outer surface of the driven shaft 41. Multiple limiting rods 43 are fixedly connected in a circumferential array on the outer surface of the positioning rings 42. A connecting rod 44 is rotatably connected to the end of the limiting rod 43 away from the positioning rings 42. A limiting crossbar 45 is rotatably connected to the end of the connecting rod 44 away from the limiting crossbar 43. A driven member 46 is slidably connected inside the limiting crossbar 45. A connecting spring 47 is fixedly connected between the outer surface of the limiting crossbar 45 and the outer surface of the limiting crossbar 43.

[0056] Each positioning ring 42 is respectively located below the corresponding filter plate 29. The vertical height of the two positioning rings 42 located below the same filter plate 29 decreases along the tilt direction of the filter plate 29, and the two positioning rings 42 are respectively located on the outer surface of the two driven rotating shafts 41.

[0057] The limit bar 45 has through slots on both sides of its inner wall. The driven member 46 has sliding cylinders fixedly connected to both ends. The sliding cylinders are slidably connected in the through slots, and a restoring spring is fixedly connected between the sliding cylinders and the slot wall. The end of the driven member 46 away from the limit bar 45 is set to be elliptical.

[0058] The overall working process and principle of the above embodiments are as follows:

[0059] Workers fixed the air inlet pipe 17 to the exhaust pipe of the powder water-soluble fertilizer production device with bolts. The exhaust gas discharged during the powder water-soluble fertilizer production process is discharged into the dust removal device housing 11 through the air inlet pipe 17. Then, the powder and other impurities contained in the exhaust gas are separated inside the dust removal device housing 11 and discharged into the dust removal device housing 11 through the dust collection equipment 15.

[0060] It should be noted that the impeller inside the dust collection device 15 rotates inside the dust collection device 15 under the drive of the output shaft of the dust removal drive motor 16, thereby guiding the exhaust gas inside the dust removal device housing 11 to flow and be discharged. The exhaust gas discharge of the dust collection device 15 is existing technology, so it will not be described in detail here. In addition, since the connection between the air inlet duct 17 and the dust removal device housing 11 is located at the bottom of the lowest filter plate 29, and this connection is located on the side with a higher vertical height of the inclined filter plate 29, the exhaust gas entering the dust removal device housing 11 through the air inlet duct 17 will be filtered by multiple filter plates 29 to separate the dust in the exhaust gas.

[0061] During the above process, as the dust removal drive motor 16 starts, the output shaft 21 fixedly connected to the output shaft end of the dust removal drive motor 16 will also rotate synchronously, thereby driving the stirring fan 22 and scraper 23 located at the bottom of the output shaft 21 to move synchronously. The stirring fan 22 is located at the bottom of the lowest filter plate 29. Therefore, when the exhaust gas enters the dust removal device housing 11 through the air inlet pipe 17, it will be evenly dispersed inside the dust removal device housing 11 under the action of the stirring fan 22. In addition, since the bottom of the dust removal device housing 11 is set as a frustum shape with gradually decreasing size, the filtered dust will gradually slide down the inner wall of the dust removal device housing 11 into the dust collection box 13. During this process, some dust will remain on the inner wall of the dust removal device housing 11. Therefore, the close fit between the scraper 23 and the inner wall of the dust removal device housing 11 makes it easy for the scraper 23 to scrape off the dust remaining on the inner wall of the dust removal device housing 11 during rotation.

[0062] When exhaust gas is injected into the dust collector housing 11 through the air inlet duct 17, the exhaust gas is discharged through the air inlet duct 17 to the area below the lowest filter plate 29 and contacts the lower surface of the filter plate 29. After being filtered by the filter plate 29, the exhaust gas is filtered again by another filter plate 29. Since the filter plates 29 are equidistantly arranged along the vertical direction and the pore size of the filter plates 29 gradually increases along the vertical direction, the dust contained in the exhaust gas can be filtered multiple times by the filter plates 29.

[0063] During the above process, due to the inclined arrangement of the filter plate 29, the exhaust gas will come into contact with the inclined bottom surface of the filter plate 29 and diffuse along the surface of the filter plate 29, thereby avoiding the filter plate 29 from being in contact with the dust-containing exhaust gas in a single position for a long time, which would cause the filter pores in that part to become clogged.

[0064] As the exhaust gas passes through the filter plate 29 layer by layer, the continuously rotating output shaft 21 will drive the fixed ring 31 on its outer surface to rotate synchronously. At this time, since the top surface of the fixed ring 31 and the bottom surface of the wedge 32 are both set as mutually fitting inclined surfaces, and the wedge 32 is horizontally rotatably connected to the outer surface of the drive shaft, and the outer surfaces on both sides of the wedge 32 are rotatably connected to the outer surface of the driven shaft 41 through the connecting rod, the position of the wedge 32 remains unchanged under the combined action of the drive shaft and the output shaft 21.

[0065] It should be noted that, in the above process, assuming that the output shaft 21 rotates clockwise under the action of the output shaft of the dust removal drive motor 16, the drive gear 24 fixedly connected to it will rotate clockwise synchronously. At this time, the two planetary gears 25 meshing with the drive gear 24 will rotate counterclockwise. Therefore, the driven shaft 41 fixedly connected to the bottom end of the planetary gear 25 will rotate counterclockwise synchronously. At this time, under the combined action of the output shaft 21 and the driven shaft 41, when the output shaft 21 rotates, the position of the wedge block 32 remains unchanged.

[0066] Therefore, when the fixed ring 31 rotates under the action of the output shaft 21, the inclined surfaces of the fixed ring 31 and the wedge block 32 will come into contact with each other, which will cause the fixed ring 31 to drive the slider 34 fixedly connected to its inner surface to move vertically in the vertical groove 33 opened on the outer surface of the output shaft 21. While the fixed ring 31 moves, it compresses the return spring 35 set below the fixed ring 31.

[0067] Multiple inclined filter plates 29 separate dust particles mixed in the exhaust gas, thereby purifying the exhaust gas generated during the production of powdered water-soluble fertilizer. The inclined structure makes the airflow direction form an angle with gravity, increasing the probability that the particles will fall naturally due to their own weight. In addition, the design of multiple filter plates 29 can achieve multi-stage interception. Large particles are first captured by the high-level coarse filter plate, while fine dust is further removed by passing through subsequent precision plates.

[0068] During the process of filtering exhaust gas, the filter plate 29 will reciprocate vertically under the action of the fixed ring 31 and the wedge block 32. When the filter plate 29 reciprocates up and down, the dust particles attached to its surface are peeled off due to inertia, thereby effectively avoiding the problem of increased wind resistance caused by mesh blockage. Moreover, the reciprocating motion of the filter plate 29 will periodically change the local pressure difference, causing the gas to penetrate the filter material in a pulse form. This unsteady flow mode can break the boundary layer effect, making it easier for small particles to be captured. In the case of multi-layer stacked arrangement, the movement of filter plates 29 at different heights can build a dynamic filtration gradient. After the lower layer coarsely filters large particles, the upper layer precision filter screen processes fine dust, forming a cascade purification effect.

[0069] Since the fixed ring 31 is horizontally rotatably connected to the inside of the filter plate 29, as the fixed ring 31 moves, it will synchronously drive the filter plate 29 and the positioning part 28 outside the filter plate 29 to move vertically downward inside the dust removal device housing 11. As the fixed ring 31 contacts the inclined surface of the wedge block 32, the fixed ring 31 will move vertically upward on the outer surface of the output shaft 21 along the trajectory of the inclined surface of the wedge block 32 and under the rebound action of the return spring 35. Thus, as the output shaft 21 continues to rotate, the filter plate 29 reciprocates along the vertical direction, thereby preventing the filter holes of the filter plate 29 from being blocked by dust after long-term use.

[0070] At the same time, as the output shaft 21 continues to rotate, the driven shaft 41 fixedly connected to the bottom surface of the planetary gear 25 will rotate synchronously, thereby driving the positioning ring 42 fixedly connected to the surface of the driven shaft 41 to rotate synchronously. As the rotation speed of the driven shaft 41 gradually increases, the centrifugal force on the limiting link 43, connecting rod 44, limiting crossbar 45 and driven member 46 set on the positioning ring 42 will also gradually increase.

[0071] At this time, the connecting rod 44, the limiting crossbar 45, and the driven member 46 located on the positioning ring 42 have two motion states. First, when the centrifugal force on the connecting rod 44 is less than the traction force of the connecting spring 47, the damping force between the two ends of the connecting rod 44 and the limiting connecting rod 43 and the limiting crossbar 45 makes the connecting rod 44 remain unchanged during rotation.

[0072] Secondly, when the centrifugal force on the connecting rod 44 is greater than the traction force of the connecting spring 47, the damping force between the two ends of the connecting rod 44 and the limiting link 43 and the limiting crossbar 45 cannot keep the connecting rod 44 constant during rotation. Therefore, the connecting rod 44 will move away from the center of the positioning ring 42 with its connection point with the limiting link 43 as the fulcrum. At the same time, under the influence of centrifugal force, the driven member 46 will also move away from the center of the positioning ring 42 inside the limiting crossbar 45.

[0073] During the above process, as the filter plate 29 moves up and down, when the filter plate 29 moves downward, the bottom surface of the filter plate 29 will contact the top surface of the driven member 46. As the driven member 46 continues to move, it will scrape the bottom surface of each filter plate 29, thereby preventing dust from accumulating at the bottom of the filter plate 29 and affecting the filtration effect of the filter plate 29.

[0074] Furthermore, during the process of the bottom surface of the filter plate 29 contacting the driven member 46, the bottom surface of the filter plate 29 will simultaneously apply a downward force to the driven member 46. Therefore, as the filter plate 29 moves downward, the filter plate 29 drives the limiting crossbar 45 and the driven member 46 to move downward in the vertical direction, causing the limiting crossbar 45 and the connecting rod 44 to change position on the limiting connecting rod 43, thereby causing the connecting spring 47 to deform.

[0075] The change in connecting rod 44 will cause the driven member 46 to move, thus preventing dust from accumulating on the surface of the contact point between the driven member 46 and the filter plate 29, which would affect the cleaning effect of the driven member 46 on the bottom surface of the filter plate 29. In addition, as the centrifugal force on the driven member 46 gradually increases, the length of the driven member 46 extending inside the limiting crossbar 45 will gradually increase. Therefore, the end of the driven member 46 away from the limiting crossbar 45 will gradually make a slight collision with the surface of the output shaft 21 located at the center of the device, which will further cause the driven member 46 to vibrate.

[0076] It should be noted that the follower 46 comes into contact with other objects only when the follower 46 extends to the maximum extent of the limiting crossbar 45. Therefore, the follower 46 will not come into contact with other objects during normal rotation.

[0077] Meanwhile, during the process described above, as the filter plate 29 descends, the limiting crossbar 45 is rotatably connected to the limiting link 43 via the connecting rod 44, which allows the driven member 46 to be in a position that can change. Therefore, the descent of the filter plate 29 can maintain continuous contact between the surface of the filter plate 29 and the driven member 46.

[0078] Therefore, during the movement of the filter plate 29, the movement of the driven member 46 will also exhibit two states.

[0079] Firstly, the bottom surface of the filter plate 29 does not contact the driven member 46. At this time, the limiting link 43, connecting rod 44, limiting crossbar 45, and driven member 46 will be in a rotating state, and the rotation state is opposite to the rotation direction of the agitating fan 22. At this time, the limiting link 43, connecting rod 44, limiting crossbar 45, and driven member 46 are similar to a rotating fan, thereby agitating the exhaust gas located below each filter plate 29, so that the exhaust gas is evenly distributed below the filter plate 29.

[0080] Secondly, the bottom surface of the filter plate 29 contacts the driven member 46. At this time, the continuously rotating driven member 46 continuously cleans the bottom surface of the filter plate 29 to prevent dust from clogging the bottom surface of the filter plate 29.

[0081] It should be noted that, since the aperture of the multiple filter plates 29 gradually increases along the vertical direction, the dust mixed in the exhaust gas will be filtered multiple times by the multiple filter plates 29, thereby removing the dust mixed in the exhaust gas. The exhaust gas after dust removal is discharged by the dust collection device 15. During the subsequent cleaning of the filter plates 29, due to the different aperture of the filter plates 29, most of the dust can pass through the multiple filter plates 29 and eventually fall onto the bottom inner wall of the dust removal device housing 11. After the dust removal drive motor 16 is turned off, the dust will be deposited inside the pull-out collection box 14. Then, the staff can remove the pull-out collection box 14 from the dust collection box 13, thereby completing the dust separation treatment of the exhaust gas.

[0082] With the setting of limit link 43, connecting rod 44, limit crossbar 45 and follower 46, when the limit link 43, connecting rod 44, limit crossbar 45 and follower 46 rotate with the driven shaft 41, they rotate in the opposite direction to the agitator fan 22 that rotates under the action of the output shaft 21, agitating the exhaust gas. The reverse airflow generated by the reverse rotation will continuously peel off the dust captured on the filter screen, preventing the bottom of the filter plate 29 from clogging.

[0083] The limiting link 43, connecting rod 44, limiting crossbar 45 and driven member 46 are designed to scrape the bottom surface of the filter plate 29 when in contact with it. The tangential force generated by the scraping action can directly destroy the adhesion between the dust and the filter material surface, avoiding the airflow reduction caused by the thickening of dust accumulation. Furthermore, the combination of physical scraping and the vibration of the filter plate 29 itself further prevents the filter plate 29 from becoming clogged.

[0084] The rotational connection between the limiting crossbar 45, the connecting rod 44, and the limiting link 43 allows the driven member 46 to be in a deformed state after contacting the filter plate 29, ensuring that the driven member 46 is stably attached to the lower surface of the inclined filter plate 29. In addition, the driven member 46 will undergo a state change as it follows the movement of the filter plate 29, keeping the driven member 46 in motion. This prevents dust from remaining on the surface of the driven member 46 after dust removal, thus avoiding affecting the next cleaning of the filter plate 29 by the driven member 46.

[0085] The arrangement of the drive gear 24 and the planetary gear 25 ensures that the rotational speed of the driven member 46 on the driven shaft 41 is greater than the rotational speed of the agitator fan 22 on the output shaft 21. The rotational speed of the driven member 46 being greater than the rotational speed of the agitator fan 22 accelerates the airflow speed after being filtered by the filter plate 29, thus preventing the exhaust gas after being filtered by multiple filter plates 29 from being blocked by the filter plates 29 and slowing down the flow speed, thereby preventing the exhaust gas from accumulating inside the dust removal device housing 11.
