Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, and particularly relates to an anti-clogging bag pulse dust collector. Background Art

[0002] A bag pulse dust collector is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] When some pulse dust collectors are in use, it is necessary to regularly discharge the dust inside the ash hopper. For example, the anti-clogging pulse bag dust collector with the application number CN202122065502.0 realizes the anti-clogging purpose by vibrating the dust inside the ash hopper with a vibrating motor. However, the vibrating motor is fixedly connected to the ash hopper, and the ash hopper is fixedly connected to the dust collector box body. When the vibrating motor works, it will drive the entire dust collector to vibrate, which will affect the normal operation of other structures of the dust collector, and the use effect is not ideal. Moreover, some dust gets damp and caked and blocks the ash hopper outlet, making it difficult to be shaken out. Some damp dust adheres to the inner wall of the ash hopper and is also not easy to be shaken off, resulting in insufficient anti-clogging effect and incomplete ash cleaning. In addition, when discharging the dust, the dust discharging height is relatively high, and it is easy to float in the air, causing environmental pollution.

[0004] The bag pulse dust collector combines the advantages of dust collectors of types such as compartment reverse blowing and pulse jetting. However, during long-term use, although the filter bag can be cleaned, when blowing or reverse blowing, since the equipment itself does not stop working, a large amount of dust will be generated and dispersed around the filter bag after blowing. Some dust will fall down, but there is still a large amount of dust that will float around the filter bag after blowing and will reattach to the filter bag under the action of the suction force of the adjacent filter bag when the filter bag starts working again. This reduces the effect of blowing or reverse blowing. Summary of the Invention

Detailed implementation mode

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Figures 1 to 7 The following shows an embodiment of the present invention.

[0028] Embodiment 1:

[0029] Figure 1 , Figure 2 and Figure 5A clogging-proof bag pulse dust collector is shown, including a dust collector body 1. Inside the dust collector body 1, a clean chamber 3 and a dust chamber 4 are separated by a horizontally arranged first partition plate 2. A number of mounting holes are provided on the first partition plate 2, and a bag filtration unit 5 extending into the dust chamber 4 is installed in each mounting hole. A pulse jet unit is installed in the dust chamber 4 opposite to each bag filtration unit 5. Vertically and horizontally criss-crossed second partition plates 6 are arranged below the first partition plate 2 to divide the lower side of the first partition plate 2 into several compartments. A track 7 is horizontally arranged below the second partition plate 6 in the dust chamber 4, and a moving component is movably installed on the track 7. A dust suction plate 8 matching the lower end opening of the compartment is liftably installed on the upper side of the moving component through a lifting component. A dust suction groove 9 is provided on the upper side of the dust suction plate 8, and a filter plate 10 is installed at the notch of the dust suction groove 9. A dust suction unit 11 is installed on the upper side of the moving component, and the air inlet end of the dust suction unit 11 is connected to the dust suction groove 9 through a dust suction bellows 12. After the bag filtration unit 5 has been used for a period of time and needs to be cleaned, first use the pulse jet unit for the first jet to blow off most of the caked dust from the bag filtration unit 5, and it will fall to the bottom of the dust chamber 4 by its own gravity. However, at this time, a large amount of floating dust still remains on the outer surface and around the bag filtration unit 5, and these dusts will be adsorbed onto the surface of the bag filtration unit 5 again when the bag filtration unit 5 starts working again, affecting the ventilation volume of the bag filtration unit 5. By moving the moving component on the track 7, the filter plate 10 is moved below the compartment, and then the lifting component is used to drive the dust suction plate 8 to move upward, so that the dust suction plate 8 fits the lower end opening of the compartment and covers the opening. Then, by starting the pulse jet unit, a second pulse jet is performed on the bag filtration unit 5 in this compartment. When jetting, the floating dust in the compartment is adsorbed onto the filter plate 10 by means of the dust suction unit 11, so as to prevent these floating dusts from returning to the surface of the bag filtration unit 5 again. After the filter plate 10 has completed adsorption, the lifting component is lowered to open the opening of the compartment, so that the bag filtration unit 5 in the compartment can start filtering work again. An air inlet pipe is arranged at a position close to the lower part of the dust chamber 4, and the gas containing impurities and dust enters the dust chamber 4 from the air inlet pipe. An exhaust pipe is arranged in the clean chamber 3, and an exhaust fan is arranged on the exhaust pipe. The gas enters the clean chamber 3 after being filtered by the bag filtration unit 5 and is discharged through the exhaust pipe or enters the next process. The bag filtration unit 5 can adopt the common structure of a cylindrical bag plus an inner support steel mesh in a bag pulse dust collector. The opening of the bag and the opening of the inner support steel mesh are sealed and installed with the mounting holes, and the gas in the dust chamber 4 enters from the outside of the bag to the inside. The pulse jet unit is the same as the structure used to realize pulse jet in the existing bag pulse dust collector, and no improvement is made in the present invention. Figure 2An example is given in [description]. The fourth lifting rod 55 drives the blowing pipe 56 and the cover 57 for closing the upper opening of the cloth bag to move up and down. During blowing, the fourth lifting rod 55 descends to seal the upper opening of the cloth bag, and air is blown into the interior of the cloth bag through the blowing pipe 56 to achieve the pulse blowing effect. Compressed air is instantaneously injected into the cloth bag through the pulse valve on the blowing pipe 56, causing the filter bag to expand and vibrate, and the dust on the surface of the cloth bag to fall off.

[0030] The moving assembly includes a support plate 13 and two mounting plates 14 vertically arranged on opposite sides of the track 7. The upper ends of the two mounting plates 14 are connected to the lower side of the support plate 13 above the track 7. A rolling wheel 15 is installed above the track 7 between the two mounting plates 14. The rolling wheel 15 is in rolling connection with the upper side of the track 7. At least two rolling wheels 15 are arranged along the length direction of the track 7. A rack 17 is arranged along the length direction on the lower side of the track 7. A first gear 16 is vertically rotatably arranged on the lower side of the track 7 between the two mounting plates 14. The first gear 16 meshes with the rack 17. A first servo motor 18 is installed on the outer side of one of the mounting plates 14. The output shaft of the first servo motor 18 is in transmission connection with the first gear 16; the upper side of the track 7 is convexly arranged, and the circumferential surface of the rolling wheel 15 is concavely arranged. By setting the first servo motor 18, the first gear 16 can be driven to rotate. Thus, by virtue of the meshing relationship between the first gear 16 and the rack 17, the two mounting plates 14 can be driven to move along the length direction of the track 7. Through the rolling wheel 15, the track 7 can be clamped up and down in cooperation with the first gear 16, so that the first gear 16 can be well meshed and driven with the rack 17. By setting the upper side of the track 7 to be convexly arranged, it can be well avoided that dust accumulates on the upper side of the track 7, resulting in jamming between the rolling wheel 15 and the track 7. By setting more than two rolling wheels 15, the stability of the support plate 13 can be improved.

[0031] A flexible sealing ring 19 is arranged around the upper edge of the surrounding dust suction plate 8. The flexible sealing ring 19 is of a hollow structure; the side surfaces of the track 7 facing the two mounting plates 14 are arranged as planes 20, and the two mounting plates 14 are both convexly provided with hemispherical sliders 21 that are respectively in sliding fit with the two planes 20. In order to prevent the two mounting plates 14 from tipping over during movement, resulting in the separation of the first gear 16 and the rack 17, by setting the hemispherical sliders 21 to fit the two planes 20 as sliding support points, three-side sliding can be formed in cooperation with the rolling wheel 15, so that the support plate 13 can be stably installed above the track 7.

[0032] A corrugated rubber sleeve 22 is provided on the upper side around the edge of the support plate 13, and the upper end of the corrugated rubber sleeve 22 is connected to the edge of the lower side of the filter plate 10. By providing the corrugated rubber sleeve 22, the space between the support plate 13 and the filter plate 10 can be well protected, preventing dust from entering this space and affecting the operation of the dust suction unit 11. At the same time, the telescopic performance of the corrugated rubber sleeve 22 can be utilized to adapt to the lifting of the lifting assembly.

[0033] The lifting assembly includes a first lifting rod 23. The lower end of the first lifting rod 23 is connected to the upper side of the support plate 13, and the upper end is connected to the lower side of the filter plate 10. More than two first lifting rods 23 are provided between the support plate 13 and the filter plate 10. By providing the first lifting rod 23, the filter plate 10 can be driven to lift above the support plate 13 by the simultaneous lifting of multiple first lifting rods 23.

[0034] A pressure relief bellows 24 and a ventilation bellows 48 are provided between the support plate 13 and the filter plate 10. The upper ends of the pressure relief bellows 24 and the ventilation bellows 48 are both connected to the bottom of the dust suction groove 9, and the lower ends are both connected to the lower side of the support plate 13. A one-way valve 25 is installed on the lower side of the support plate 13 at the lower end of the pressure relief bellows 24, and the one-way valve 25 conducts unidirectionally from the upper end to the lower end of the pressure relief bellows 24; a solenoid valve 49 for controlling its on-off is installed on the upper side of the support plate 13 for the ventilation bellows 48. When the pulse jetting unit performs the second jetting, since the filter plate 10 blocks the lower end of the compartment, the air generated by the jetting cannot be discharged through the lower end of the compartment and can only enter the dust suction groove 9 through the filter plate 10, and then enter the dust suction unit 11 through the dust suction bellows 12 and be discharged. If the instantaneous air pressure is too large, it may damage the motor or rotating structure inside the dust suction unit 11. Therefore, by providing the pressure relief bellows 24 as an exhaust channel, it can withstand most of the airflow generated by the pulse jetting, and the airflow passes through the pressure relief bellows 24 and is discharged from the one-way valve 25. By providing the one-way valve 25, the gas in the dust chamber 4 can be prevented from entering the compartment through the pressure relief bellows 24. The ventilation bellows 48 can assist the pressure relief bellows 24 in relieving pressure when the solenoid valve 49 is opened.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, as Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, a cleaning box 26 is provided on the outer wall of the dust collector body 1 on one axial side of the track 7. The cleaning box 26 is separated into a cleaning chamber 28 and a driving chamber 29 along the axial direction of the track 7 by a third partition plate 27. The dust chamber 4 is connected to the cleaning chamber 28 through a connecting hole 30. A rotating hole 31 aligned with the track 7 is provided on the third partition plate 27. A first rotating shaft 32 is rotatably provided in the rotating hole 31. The end of the track 7 passes through the cleaning chamber 28 and is coaxially connected to the end of the first rotating shaft 32. The other end of the first rotating shaft 32 is connected to the driving chamber 29. A second gear 33 is coaxially connected to the moving cavity 29, a second servo motor 34 is installed in the driving cavity 29, a third gear 35 is installed on the output shaft of the second servo motor 34, and the second gear 33 and the third gear 35 are meshed and connected; a closed door for controlling the opening and closing of the connecting hole 30 is provided at the position of the connecting hole 30 of the cleaning box 26; a funnel groove 36 is provided in the lower recess of the cleaning cavity 28, and an external dust collection device 37 is connected to the bottom of the funnel groove 36; an air hole 44 connected to the cleaning cavity 28 is provided on the upper side of the cleaning box 26. Figure 2 In the figure, the dust collecting plate 8 indicated by the dotted line in the right cleaning chamber 28 is in the cleaning chamber. The end of the track 7 away from the first rotating shaft 32 is rotatably connected to the wall of the dust chamber 4 through the second rotating shaft 58, so that the second rotating shaft 58 can cooperate with the track 7 to achieve rotation. After working a certain number of times, the filter plate 10 will not be able to continue working due to a large amount of dust accumulated on the surface. Therefore, it is necessary to effectively clean the filter plate 10 to avoid clogging of the filter plate 10. When the dust collecting plate 8 is in the dust chamber 4, the dust chamber 4 and the cleaning chamber 28 are blocked by closing the closed door to prevent dust from entering the cleaning chamber 28. Figure 3 As shown, when the dust collecting plate 8 needs to be cleaned, the closed door is opened, and then the dust collecting plate 8 is moved into the cleaning chamber 28 by moving the assembly, and after entering the cleaning chamber 28, the connecting hole 30 is closed by the closed door. After closing the connecting hole 30, the third gear 35 is driven to rotate by the second servo motor 34, so that the second gear 33 is rotated, so that the track 7 can be turned over by 180 degrees, so that the dust collecting plate 8 can be turned over to the bottom of the track 7, as shown in FIG. Figure 4As shown, align the filter plate 10 with the funnel groove 36, and drive the dust suction plate 8 to move downward through the lifting assembly, so that the edge of the dust suction plate 8 fits against the groove wall of the funnel groove 36. Then start the external dust suction device 37. With the suction force generated by the external dust suction device 37, air can enter the dust suction groove 9 from the back of the filter plate 10 to backwash the filter plate 10, realizing the cleaning of the filter plate 10. Through the cooperation of the air holes 44 and the ventilation bellows 48, gas can smoothly enter the dust suction groove 9 and then backwash the filter plate 10 from the back of the filter plate 10. After the cleaning is completed, turn the dust suction plate 8 above the track 7. And through the cleaning chamber 28, when the bag filter unit 5 does not need to be cleaned, the dust suction plate 8 can be stored to prevent the dust suction plate 8 from contacting dust in the dust chamber 4 for a long time.

[0037] The closing door includes an upper door plate 38, a lower door plate 39, a second lifting rod 40 and a third lifting rod 41. The cleaning box 26 is respectively provided with an upper door hole 42 and a lower door hole 43 on the upper and lower sides of the communication hole 30. The upper door plate 38 is slidably arranged up and down in the upper door hole 42. The second lifting rod 40 is installed above the cleaning box 26, and the lifting end faces downward and is connected to the upper side of the upper door plate 38. The lower door plate 39 is slidably arranged up and down in the lower door hole 43. The third lifting rod 41 is installed below the cleaning box 26, and the lifting end faces upward and is connected to the lower side of the lower door plate 39. The lower side of the upper door plate 38 and the upper side of the lower door plate 39 are both recessed with notches for the rotation of the track 7, and flexible fitting pieces are arranged in the notches. With such a setting, when the dust suction plate 8 needs to enter the cleaning chamber 28 or enter the dust chamber 4, the second lifting rod 40 and the third lifting rod 41 contract to drive the upper door plate 38 to move upward and the lower door plate 39 to move downward, opening the communication hole 30, so that the dust suction plate 8 can smoothly enter and exit. After the dust suction plate 8 enters and exits, the second lifting rod 40 and the third lifting rod 41 extend to drive the upper door plate 38 to move downward and the lower door plate 39 to move upward, closing the communication hole 30. By setting the notches, when the communication hole 30 is closed, the track 7 will not be squeezed, and the flexible fitting pieces can well fill the gap between the notches and the track 7.

[0038] The driving chamber 29 is respectively installed with a first electromagnet 45 and a second electromagnet 46 on the opposite sides of the first rotating shaft 32. A magnetic attraction iron plate 47 is installed on the side wall of the first rotating shaft 32. When the magnetic attraction iron plate 47 rotates to both sides and is in a horizontal state along with the first rotating shaft 32, it is magnetically connected to the first electromagnet 45 and the second electromagnet 46 respectively. The first rotating shaft 32 is rotationally connected to the hole wall of the rotating hole 31 through a first rotating shaft bearing. As Figure 7 shown Figure 7The dotted line on the left side is a schematic diagram of the magnetic iron plate 47 rotating to the left. When it is necessary to use the track 7 to move the mobile component along the track 7 and move the dust collecting plate 8 to the bottom of the corresponding compartment, the second servo motor 34 is used to drive the track 7 to rotate to the position where the rack 17 is facing downward. At this time, the first electromagnet 45 is in contact with the magnetic iron plate 47, and the first electromagnet 45 is energized to make the first electromagnet 45 and the magnetic iron plate 47 firmly attached together, so that when the mobile component moves on the track 7, the track 7 will not flip. When it is necessary to clean the dust collecting plate 8, the second servo motor 34 is used to drive the track 7 to flip, and the first electromagnet 45 is powered off. When the rack 17 rotates to the upward position, the second electromagnet 46 is in contact with the magnetic iron plate 47. At this time, the second electromagnet 46 is energized to make the second electromagnet 46 and the magnetic iron plate 47 firmly attached together, so that the track 7 will not flip when cleaning the filter plate 10.

[0039] A fixing rod 50 is horizontally arranged on the third partition plate 27 aligned with the support plate 13, and a sliding hole 51 is arranged at one end of the fixing rod 50 toward the support plate 13, and a pressure sensor 52 is arranged at the bottom of the sliding hole 51, and a detection rod 53 is slidably arranged in the sliding hole 51, and one end of the detection rod 53 is placed outside the sliding hole 51, and the other end is connected to the pressure sensor 52 by a spring 54 in the sliding hole 51. By setting the fixing rod 50 and the detection rod 53, the support plate 13 can be positioned and calibrated after entering the cleaning chamber 28. After the support plate 13 contacts the detection rod 53, it will push the detection rod 53 to slide in the sliding hole 51, and compress the spring 54, so that the pressure sensor 52 generates a pressure value, and the displacement distance of the detection rod 53 can be calculated according to the size of the pressure value, so as to calculate the stop position of the support plate 13 according to the initial position and displacement position of the end of the detection rod 53. This position is used to judge whether the stop position of the support plate 13 in the cleaning chamber 28 is the set position. If it is not the set position, the first servo motor 18 is required to drive the support plate 13 to the corresponding position until it moves to the set position, so that the displacement position of the subsequent support plate 13 can be accurately controlled by the first servo motor 18, so as to avoid the support plate 13 not moving into place in the dust chamber 4, resulting in the dust collecting plate 8 failing to block the opening of the compartment well. In addition to the solution of using the detection rod 53 in conjunction with the sensor, proximity sensors, displacement sensors, etc. can also be used to achieve the same function.
