Description

Technical Field

[0001] The invention relates to the technical field of pulse bag dust collectors, and in particular to a dust cleaning device for a pulse bag dust collector. Background Art

[0002] A bag filter is a dry dust filtering device. The filter bag is made of textile filter cloth or non-textile felt. It uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter bag, the dust is retained, so that the gas is purified. However, after the filter bag of the bag filter has been used for a period of time, a layer of dust will accumulate on the surface of the filter bag, resulting in a significant reduction in the dust removal efficiency and effect of the bag filter. Especially after using a filter bag that can block fine dust particles, as the filter holes become smaller, as long as a part of the micro dust particles are attached, the filtering capacity of the filter bag will be seriously reduced. The pulse bag dust collector adopts pulse backblowing for cleaning. It needs to be opened frequently for backblowing cleaning during use. The pulse backblowing during cleaning is opposite to the flow direction of the dust-laden gas. Cleaning can only be performed when the bag dust collector is stopped, resulting in frequent start and stop of the bag dust collector, repeated expansion and impact vibration of the filter bags, which reduces the life of the filter bags and seriously affects the working efficiency of the bag dust collector. Summary of the invention

[0003] In order to solve the above-mentioned problem, the present invention provides a cleaning device for a pulse bag dust collector, which is installed at the outlet of the filter bag and extends into the filter bag.

DETAILED DESCRIPTION

[0016] The structure of the pulse bag dust collector applicable to the present invention is explained below, and the technical solution of the present invention is clearly and completely described in conjunction with the accompanying drawings.

[0017] In the description of the present invention, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not limit the referred device or element to have a specific orientation, be constructed and operate in a specific orientation.

[0018] The structure of the bag filter mainly includes a box body 30 with an air inlet and an air outlet, a partition 31 arranged in the box body 30 and dividing the inner cavity of the box body 30 into two upper and lower cavities, a mounting port 32 arranged on the partition 31, a bag drum frame 33 arranged at the lower end of the partition 31 and corresponding to the mounting port 32, and a filter bag 34 sleeved on the bag drum frame 33. The air inlet is connected to the cavity below the partition 31, and the air outlet is connected to the cavity above the partition 31. The bag opening of the filter bag 34 is fixed on the installation opening 32. The bag body of the filter bag 34 is sleeved on the outside of the bag drum frame 33. The bag opening of the filter bag 34 corresponds to the installation opening 32. The bag drum frame 33 is a cylindrical structure adapted to the filter bag 34. The dust-containing gas enters from the air inlet, passes through the filter bag 34 on the bag drum frame 33, enters the filter bag 34, and then enters the cavity above the partition 31 from the opening of the filter bag 34, i.e., the installation opening 32, and finally flows out from the air outlet to complete the filtration.

[0019] The structure of the pulse back-blowing device mainly includes a pulse pipeline 35 and a pulse nozzle 36. The pulse pipeline 35 is arranged above the partition 31 and connected to an external air source. The pulse nozzle 36 is arranged above the installation port 32. The pulse nozzle 36 is directed toward the filter bag 34 in the installation port 32. The pulse back-blowing is to transport the compressed air to the pulse nozzle 36 through the pulse pipeline 35, and then the pulse nozzle 36 is used to spray toward the filter bag 34. The dust will accumulate on the outer wall of the filter bag 34. The compressed air is sprayed from the inside of the filter bag 34 to the outside to blow away the dust on the outer wall of the filter bag 34, and the cleaning is completed.

[0020] The present invention is based on the structure of the above-mentioned pulse bag dust collector and aims at the disadvantage that the above-mentioned pulse bag dust collector needs to perform backblowing cleaning operations frequently. A cleaning device suitable for the above-mentioned pulse bag dust collector is designed. The cleaning device is fixed on the partition 31 and is located in the filter bag 34, does not occupy other space, and only needs to be added to the structure of the above-mentioned pulse bag dust collector without changing the original structure. The modification cost and operation difficulty are greatly reduced.

[0021] like Figure 1-6 As shown, the present invention provides a dust cleaning device for a pulse bag dust collector, comprising a support frame 1, a driving mechanism 2 arranged on the support frame 1, and a rotating frame 3 connected to the driving mechanism 2 in a transmission manner, and also comprising a screw rod 4 rotatably arranged on one side of the lower end of the rotating frame 3, a monitoring motor 5 arranged on the rotating frame 3 and connected to the screw rod 4 in a transmission manner, a guide rod 6 arranged on both sides of the screw rod 4 and parallel to the screw rod 4, a connecting frame 7 arranged between the screw rod 4 and the guide rod 6, a lifting seat 8 arranged on the screw rod 4, a monitoring module 9 arranged on the lifting seat 8, a dust cleaning rod 10 arranged on one side of the guide rod 6, and a paddle 11 arranged on the dust cleaning rod 10; the driving mechanism 2 is arranged on the support frame 1, and the monitoring mechanism 2 is connected to the driving mechanism 2. The driving mechanism 2 drives the rotating frame 3 to rotate and drives the screw rod 4 to perform circumferential motion. The screw rod 4 and the guide rod 6 are both vertically arranged and parallel to each other. The upper end of the screw rod 4 is transmission-connected to the driving end of the monitoring motor 5. The lifting seat 8 is mounted on the screw rod 4 and the lifting seat 8 is slidingly mounted on the guide rod 6 on both sides. The monitoring motor 5 drives the screw rod 4 to rotate and drives the lifting seat 8 to lift and lower on the screw rod 4. The middle part of the connecting frame 7 is rotationally connected to the screw rod 4 and the two sides are fixed to the guide rod 6. The cleaning rod 10 is vertically and parallelly arranged on the outside of the guide rod 6. The paddle plate 11 is fixed on the outside of the cleaning rod 10 and multiple plates are arranged at intervals along the vertical direction of the cleaning rod 10.

[0022] The support frame 1 is installed on the mounting opening 32 of the bag-type dust collector partition 31, and is located at the upper end of the mounting opening 32, playing a fixed supporting role. The driving mechanism 2 is installed on the support frame 1, and is used to drive the rotating frame 3 to rotate. The rotating frame 3 is located in the mounting opening 32 of the bag-type dust collector, that is, the bag opening of the filter bag 34. The screw rod 4 is vertically inserted downward into the filter bag 34. The upper end of the screw rod 4 is rotatably connected to the lower end of one side of the rotating frame 3, adjacent to the filter bag 34, reducing the space occupied by the filter bag 34. When the screw rod 4 moves circumferentially under the drive of the rotating frame 3, the influence on the filtering effect of the filter bag 34 can also be reduced.

[0023] The guide rods 6 are fixed on both sides of the connecting frame 7, and the connecting frame 7 is mounted on the screw rod 4. The connecting frame 7 and the screw rod 4 are rotationally connected and longitudinally limited, that is, the rotation of the screw rod 4 will not drive the connecting frame 7 to rotate synchronously, and the connecting frame 7 will not slide up and down on the screw rod 4.

[0024] The lifting seat 8 is adapted to be installed with the screw rod 4, that is, the lifting seat 8 is provided with a sleeve hole adapted to the screw rod 4, and the inner wall of the sleeve hole is adapted to the thread on the outer periphery of the screw rod 4. The rotation of the screw rod 4 can drive the lifting seat 8 to perform lifting and lowering movements on the screw rod 4. The lifting seat 8 is slidably connected with the guide rod 6, that is, sleeve holes adapted to the guide rod 6 are provided on both sides of the lifting seat 8, and the inner wall of the sleeve hole and the outer periphery of the guide rod 6 are smooth surfaces, forming a sliding sleeve connection.

[0025] The monitoring module 9 on the lifting seat 8 can monitor the environment inside the filter bag 34. The monitoring module 9 can be a camera, which can collect images inside the filter bag 34 by sliding the lifting seat 8 up and down. It can also be a wind speed sensor, which can monitor the gas flow rate in the filter bag 34 and provide reference data for the user. Due to the existence of the connecting frame 7, it is necessary to arrange the lifting seat 8 and the monitoring module 9 according to the number and position of the connecting frame 7. A group of lifting seats 8 and monitoring modules 9 are arranged between every two adjacent connecting frames 7 to ensure that the entire filter bag 34 can be monitored. The guide rod 6 can improve the sliding stability of the lifting seat 8, and can also cooperate with the screw rod to form a frame structure to further improve the stability of the overall structure.

[0026] A cleaning rod 10 is installed on the outside of each of the two guide rods 6. A paddle 11 is installed at a position corresponding to the inner wall of each cleaning rod 10 and the filter bag 34. The end of the paddle 11 contacts the inner wall of the filter bag 34. The end of the paddle 11 is in an arc shape to avoid scratching the filter bag 34.

[0027] In this design, the driving mechanism 2 drives the rotating frame 3 to rotate, and the rotation of the rotating frame 3 drives the screw rod 4, the guide rod 6, the cleaning rod 10 and the paddle plate 11 to move circumferentially along the inner wall of the filter bag 34, so that the filter bag 34 is vibrated by the paddle movement to achieve the purpose of cleaning, and the paddle plate 11 has little resistance to the circumferential movement, and the impact on the filter bag 34 is also greatly reduced.

[0028] The rotational connection described above and below belongs to conventional technical means in this field, and this design does not make any structural limitations or specific descriptions for this. For example: a bearing connection is adopted, a bearing seat is installed on the rotating frame 3, and the upper end of the screw rod 4 is fixed in the bearing center hole in the bearing seat to achieve a rotational connection.

[0029] The paddle plate 11 in this design is installed when the outer wall of the filter bag 34 is in a flat state. After installation, the paddle plate 11 conflicts with the inner wall of the filter bag 34 in a flat state. However, this design is to clean dust when the bag filter is in a working state. The filter bag 34 in the working state is affected by the dust-laden airflow and is in a state of inward contraction. The paddle plate 11 will prop up the corresponding inner wall of the filter bag 34 outward, and the filter bag 34 will remain in an inward contraction state. The paddle plate 11 moves circumferentially along the filter bag 34, which will cause the filter bag 34 to agitate, and the cleaning effect is better. The position of the paddle plate 11 corresponds to the position where the filter bag 34 will contract, that is, the gap position of the bag drum frame 33.

[0030] like Figure 1 As shown, it also includes a connecting plate 12 arranged between the cleaning rod 10 and the guide rod 6, and a swing motor 13 arranged on the connecting plate 12; the connecting plate 12 is provided with at least two and is respectively fixed on the upper end and the lower end of the guide rod 6, the upper end and the lower end of the cleaning rod 10 are respectively rotatably connected to the connecting plate 12, and the swing motor 13 is transmission-connected to one end of the cleaning rod 10.

[0031] One end of the two connecting plates 12 is fixed to the upper and lower ends of the guide rod 6 respectively, and will not hinder the sliding of the lifting seat 8. The connection method of the cleaning rod 10 and the other end of the connecting plate 12 is a rotating connection. The driving end of the swing motor 13 is directly fixed to one end of the cleaning rod 10 downward. The swing motor 13 drives the cleaning rod 10 to rotate, and the pressing force between the paddle plate 11 and the filter bag 34 can be adjusted. The use of filter bags 34 of different materials can effectively reduce the wear on the filter bag 34. At the same time, when cleaning, the swing motor 13 can be selected to drive the cleaning rod 10 to swing, so that the paddle plate 11 beats the inner wall of the filter bag 34, thereby increasing the vibration frequency and vibration intensity of the filter bag 34, and further improving the cleaning effect.

[0032] like Figure 2 As shown, the support frame 1 includes a support plate 14 and a plurality of support plates 15 annularly arranged on the lower end or outer periphery of the support plate 14, wherein at least three support plates 15 are arranged equidistantly, the upper ends of the support plates 15 are fixed to the outer periphery or lower end of the support plate 14, and the lower ends are inclined outward, and the support plate 14 is provided with a plurality of ventilation holes.

[0033] The support frame 1 adopts a triangular support structure, and three support plates 15 push the support plate 14 upward so that the support plate 14 does not directly block the bag opening of the filter bag 34. Combined with the hollow support plate 14, the influence on the air flow can be effectively reduced. The support plate 14 is a flat plate structure, which is convenient for the installation of other components. The whole structure is stable and has low deadweight. like Figure 2-3 As shown, the driving mechanism 2 includes a fixed column 16 fixed to the lower end of the support plate 14, a rotating column 17 coaxially arranged at the lower end of the fixed column 16, and a driving fan 18 fixed on the rotating column 17; the fixed column 16 and the rotating column 17 are both vertically arranged, the upper end of the fixed column 16 is fixed to the lower end of the support plate 14, the upper end of the rotating column 17 is rotatably connected to the lower end of the fixed column 16, the driving fan 18 rotates synchronously with the rotating column 17, and the lower end of the rotating column 17 is fixed to the center of the rotating frame 3.

[0034] The fixed column 16 is fixedly connected to the support plate 14, the rotating column 17 is rotatably connected to the fixed column 16, and the driving fan 18 is set and fixed on the rotating column 17. The driving fan 18 refers to a sleeve in the middle for being set and fixed on the rotating column 17 and a plurality of fan blades circumferentially arranged on the outer periphery of the sleeve. The driving fan 18 is located above the mounting port 32 of the partition 31. When the airflow passes through, it drives the driving fan 18 to rotate. The rotation of the driving fan 18 drives the rotating frame 3 to rotate, thereby driving the screw 4, the guide rod 6, the cleaning rod 10 and the paddle plate 11 to perform circumferential movement in the filter bag 34. No motor is required, and no separate control is required. When the bag dust collector is in working condition, the cleaning device is also in cleaning working condition, which simplifies the structure required for driving and transmission, has low cost and is easy to install.

[0035] like Figure 3 As shown, the rotating frame 3 includes an outer ring plate 19, a center plate 20 arranged on the inner side of the outer ring plate 19, and a connecting plate 12 arranged between the outer ring plate 19 and the center plate 20. The outer ring plate 19 and the center plate 20 are concentrically arranged, the upper end of the center plate 20 is fixed to the lower end of the rotating column 17, and the outer ring plate 19 is rotatably connected to the upper end of the screw rod 4.

[0036] The center position of the center plate 20 is the fixed position of the rotating frame 3 and the rotating column 17. The outer ring plate 19 is adapted to the size of the installation opening 32, and can be inserted from the installation opening 32 and located at the bag opening of the filter bag 34. The outer ring plate 19 and the center plate 20 are used to form a rotating frame 3 with a hollow structure, which greatly reduces the obstruction of the rotating frame 3 to the passing airflow at the bag opening, reduces its own weight, and reduces the burden on the support frame 1.

[0037] like Figure 1-3As shown, a back-blowing cylinder 21 is also provided at the lower end of the support plate 14, and avoidance holes for the back-blowing cylinder 21 to pass through are provided in the fixed column 16 and the rotating column 17, as well as on the rotating frame 3. The upper end of the back-blowing cylinder 21 is fixed to the support plate 14, and the lower end passes through the fixed column 16, the rotating column 17 and the rotating frame 3 in turn through the avoidance hole and extends downward.

[0038] The fixed column 16 and the rotating column 17 are both cylindrical structures with a through hole in the center. A through hole is also provided at the position of the central plate 20 of the rotating frame 3 to form an avoidance hole. A backblowing cylinder 21 is inserted into the avoidance hole. The backblowing cylinder 21 is inserted from the top of the support frame 1 and extends downward into the filter bag 34 of the mounting port 32. The pulse nozzle 36 is inserted at the upper end of the backblowing cylinder 21. The backblowing airflow enters the filter bag 34 along the backblowing cylinder 21 to complete the backblowing cleaning. This design can retain the backblowing cleaning function of the original bag-type dust collector without changing the original structure. When the bag-type dust collector is running, the cleaning device of this design performs cleaning. When the bag-type dust collector stops working, the original backblowing device performs cleaning. The two are used in combination, and the cleaning effect is greatly improved, and the bag-type dust collector does not need to be frequently started and stopped.

[0039] like Figure 4-5 As shown, it also includes a flapping mechanism arranged at the lower end of the guide rod 6, and the flapping mechanism includes a mounting frame 22 fixed between the guide rods 6, an electric push rod 23 arranged on the mounting frame 22, a rack 24 arranged on the electric push rod 23 and connected to the telescopic end of the electric push rod 23, a mounting seat 25 arranged on the mounting frame 22 and located below the rack 24, a gear 26 rotatably arranged on the mounting seat 25, a hinge seat 27 arranged at the lower end of the mounting seat 25, a flapping plate 28 hinged to one side of the hinge seat 27, and a connecting rod 2 arranged between the flapping plate 28 and the gear 26. 9; the mounting frame 22 is fixed between the guide rods 6 and is located at the lower end of the screw rod 4 and is spaced apart from the screw rod 4. The telescopic end of the electric push rod 23 is vertically downward and fixed to the upper end of the rack 24. One side of the rack 24 is meshed with the gear 26. The upper end of the connecting rod 29 is hinged to one side of the end face of the gear 26 to form an eccentric connection. The lower end of the connecting rod 29 is hinged to the flapping plate 28. The electric push rod 23 drives the rack 24 to move up and down and drives the gear 26 to rotate. The rotation of the gear 26 drives the flapping plate 28 to swing on one side of the hinge seat 27 through the connecting rod 29.

[0040] The flapping mechanism is installed below the guide rod 6 and the screw rod 4 to clean the bottom of the filter bag 34. The electric push rod 23 drives the rack 24 to descend vertically, driving the gear 26 on the mounting seat 25 to rotate. The gear 26 is hinged with a connecting rod 29 at an eccentric position. The rotation of the gear 26 drives the connecting rod 29 to move downward, pushing the outer end of the flapping plate 28 to swing downward, thereby flapping the bottom of the filter bag 34. The upper end of the hinged seat 27 is fixed to the lower end of the mounting seat 25 for installing and supporting the flapping plate 28. The inner end of the flapping plate 28 is hinged to the mounting seat 25, and the structure is more stable. The cleaning device of the present design is against the inner wall of the filter bag 34 and performs a circular motion along the inner wall of the filter bag 34. The flapping mechanism flaps along the bottom edge of the filter bag 34 in a circumferential motion without affecting the passage of airflow.

[0041] like Figure 4-5 As shown, the gear 26, the connecting rod 29 and the flapping plate 28 are provided in two groups, teeth are provided on both sides of the rack 24, the gears 26 are arranged side by side on the mounting seat 25, the lower end of the rack 24 is located between the two gears 26 and passes through, and the two sides of the rack 24 are respectively meshed with the two gears 26, the flapping plate 28 is symmetrically arranged on both sides of the hinge seat 27, and the connecting rod 29 is respectively hinged between the two gears 26 and the two flapping plates 28.

[0042] Without increasing or changing the driving and transmission structure, the one beating plate 28 is changed into two beating plates 28, and the dust cleaning effect of beating and vibration is better.

[0043] like Figure 1 As shown, the monitoring module 9 includes a camera and a wind speed sensor.

[0044] The monitoring module 9 in this design is mainly a camera and a wind speed sensor, which can monitor the image and air flow rate in the filter bag 34.
