Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a filter cartridge combined dust collector. Background Technology

[0002] Cartridge dust collectors are widely used in industrial dust removal. They use cartridges as the main filtration medium and can effectively capture dust and particulate matter in the air. The working principle of a cartridge dust collector is to introduce dust-laden gas into the equipment through airflow. When the gas passes through the cartridge, the dust is trapped by the filter material on the surface or inside of the cartridge, and the purified air is discharged through the cartridge.

[0003] In existing cartridge dust collectors, the built-in filter cartridges are generally installed in fixed positions, and the air inlet of the device is also set in a fixed position. As a result, the amount of solid impurities accumulating on the outer side of the filter cartridge near the air inlet is much greater than the amount of impurities accumulating on the outer wall of the filter cartridge at other positions. This prevents the filter cartridge from achieving its filtration effect evenly, and the overall filtration effect needs to be improved. At the same time, existing cartridge dust collectors directly draw dusty air into the device and process it through the filter cartridges, resulting in a heavy workload and requiring improvement in practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a cartridge dust collector. It improves upon the existing cartridge dust collectors where the built-in cartridges are generally installed in fixed positions, and the air inlet is also set in a fixed position. As a result, the amount of solid impurities accumulated on the outer side of the cartridge near the air inlet is much greater than the amount of impurities accumulated on the outer wall of the cartridge at other positions, which cannot evenly exert the filtration effect of the cartridges and the overall filtration effect needs to be improved. At the same time, existing cartridge dust collectors directly draw dusty air into the device and process it through the cartridges, resulting in a high workload and a need to improve practicality.

[0005] A cartridge dust collector includes a protective outer casing, a support base, a door, a dust removal control mechanism, a combination installation mechanism, and a pre-dust removal mechanism: the protective outer casing is fixedly installed on top of the support base, and a door is rotatably installed on the side of the protective outer casing via a hinge assembly;

[0006] The dust removal control mechanism includes an auxiliary support base, a negative pressure fan, an exhaust pipe, and a limiting partition. The auxiliary support base is fixedly installed on the inner side wall of the protective outer casing, and the negative pressure fan is fixedly installed on the outer top wall of the auxiliary support base. The exhaust pipe is installed on the outer side wall of the protective outer casing at the position of the negative pressure fan. The limiting partition is located directly below the auxiliary support base and is connected to the inner side wall of the protective outer casing.

[0007] Preferably, the filter cartridge body is installed in a circumferential manner at equal intervals below the limiting partition, the protective outer box is connected to the outer wall of the side of the filter cartridge body by an air inlet pipe, the bottom inner wall of the protective outer box is equipped with a collection box, and the top of the collection box is fitted with an auxiliary feeding hopper.

[0008] Preferably, the combined installation mechanism includes a limiting plate, a cylindrical through groove, an auxiliary installation ring, and a threaded ring. The limiting plate is rotatably installed inside the limiting partition. An auxiliary support ring is provided on the outer side wall of the limiting plate at the middle position. The inner side of the limiting partition has a corresponding annular groove for the auxiliary installation ring to slide. The top outer wall of the limiting plate has a cylindrical through groove that is evenly spaced and runs through it. The bottom outer wall of the limiting plate at the cylindrical through groove position has an auxiliary installation ring. The bottom end of the auxiliary installation ring has a corresponding annular threaded groove for the threaded ring to be threaded. The threaded ring is fixedly installed above the filter cartridge body. A drive motor is provided on the top outer wall of the protective outer casing.

[0009] Preferably, the top outer wall of the drive shaft at the output end of the drive motor is connected to the bottom outer wall of the drive shaft, and the top outer wall of the drive shaft is connected to the top outer wall of the limiting plate.

[0010] Preferably, the pre-dust removal mechanism includes a filter plate, a limiting T-block, and a supporting spring. The filter plate is slidably installed on the inner side wall of the air inlet pipe. The bottom outer wall and top outer wall of the filter plate are symmetrically provided with limiting T-blocks. The bottom inner wall and top outer wall of the air inlet pipe are respectively provided with limiting T-grooves for sliding installation of the limiting T-blocks. A supporting spring is connected between the outer side wall of the limiting T-block and the inner bottom wall of the limiting T-groove.

[0011] Preferably, a storage box is fitted to the bottom outer wall of the air inlet pipe, and a positioning mounting strip is symmetrically arranged on the side outer wall of the storage box at the top position. A bracket for inserting the positioning mounting strip is symmetrically arranged on the bottom outer wall of the air inlet pipe. The bracket is L-shaped, and a square through groove communicating with the storage box is opened through the bottom outer wall of the air inlet pipe at the side position of the filter plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. When this cartridge dust collector is in use, the filter cartridges are designed to be rotated and installed by a motor-driven assembly. During actual operation, the rotating working trajectory of the filter cartridges can evenly adsorb and distribute dust and impurities on the outside of multiple filter cartridges. This prevents the phenomenon of excessive differences in the distribution of dust and impurities due to the installation distance of the filter cartridges, greatly improving the dust processing rate of the filter cartridges. The overall structure design is simple and the practical effect is good.

[0014] 2. When this cartridge dust collector is in use, the filter plate assembly is installed inside the air inlet pipe. The filter plate can isolate some dust and impurity particles in the air to the side of the filter plate by its filtration effect. Combined with the secondary filtration process of the filter cartridges in the device, the graded treatment greatly reduces the workload of the filter cartridges. At the same time, the change of pressure difference between the inside and outside of the device and the movement trajectory of the spring assembly can achieve the vibration cleaning effect on the outer wall of the filter plate. The overall structure is ingeniously designed and has good practical effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-5As shown, a cartridge dust collector includes a protective outer casing 1, a support base 2, a door 3, a dust removal control mechanism 4, a combination installation mechanism 5, and a pre-dust removal mechanism 6. The protective outer casing 1 is fixedly installed on the top of the support base 2, and the door 3 is rotatably installed on the side of the protective outer casing 1 via a hinge assembly.

[0023] The dust removal control mechanism 4 includes an auxiliary support base 41, a negative pressure fan 42, an exhaust pipe 43, and a limiting partition 44. The auxiliary support base 41 is fixedly installed on the inner side wall of the protective outer box 1. The negative pressure fan 42 is fixedly installed on the outer top wall of the auxiliary support base 41. The exhaust pipe 43 is installed through the outer side wall of the protective outer box 1 at the position of the negative pressure fan 42. The limiting partition 44 is located directly below the auxiliary support base 41 and is connected to the inner side wall of the protective outer box 1. The filter cartridge body 45 is installed in a circular manner at equal intervals below the limiting partition 44. The air inlet pipe 46 is installed through the outer side wall of the protective outer box 1 at the position of the filter cartridge body 45. The collection box 47 is installed on the inner bottom wall of the protective outer box 1, and the top of the collection box 47 is fitted with an auxiliary feeding hopper.

[0024] When the entire control device needs to be turned on for dust removal, the negative pressure fan 42 needs to be turned on first. When the negative pressure fan 42 is turned on, a low-pressure area will be automatically formed inside the protective outer casing 1. Then, the dusty air will automatically enter the protective outer casing 1 through the air inlet pipe 46. The dirty air entering the protective outer casing 1 will first come into contact with the outer wall of the filter cartridge body 45. The polluted air will be filtered through the outside of the filter cartridge body 45 and then enter the cartridge and rise to be discharged to the outside of the device through the exhaust pipe 43. Dust and particulate matter are captured by the filter material on the outside of the filter cartridge body 45, while clean air flows out through the inner wall of the filter cartridge. In this process, solid particles in the air can be effectively captured and removed. The collection box 47 is set to collect the dust and impurities that have accumulated and fallen on the outside of the filter cartridge body 45, while the feed hopper is set to facilitate the centralized guidance and collection of impurities. The pulse valve assembly set on the top of the filter cartridge body 45 can be installed on the top of the filter cartridge body 45 using the existing component structure. It is an existing technical means and has not been optimized or improved, so it will not be described in detail here.

[0025] The combined installation mechanism 5 includes a limiting plate 51, a cylindrical through groove 52, an auxiliary installation ring 53, and a threaded ring 54. The limiting plate 51 is rotatably installed inside the limiting partition 44. An auxiliary support ring is provided on the outer side wall of the limiting plate 51 at the middle position. The inner side of the limiting partition 44 is provided with an annular groove for the auxiliary installation ring 53 to slide. The top outer wall of the limiting plate 51 is provided with a cylindrical through groove 52 at equal intervals. The bottom outer wall of the limiting plate 51 at the cylindrical through groove 52 is provided with an auxiliary installation ring 53. The bottom end of the auxiliary installation ring 53 is provided with an annular threaded groove for the threaded ring 54 to be threaded. The threaded ring 54 is fixedly installed above the filter cartridge body 45. The top outer wall of the protective outer box 1 is provided with a drive motor 55. The top outer wall of the drive motor 55 is connected to the top outer wall of the drive shaft 56. The bottom outer wall of the drive shaft 56 is connected to the top outer wall of the limiting plate 51.

[0026] When the filter cartridge body 45 needs to be installed below the limiting plate 51, simply adjust the filter cartridge body 45 to the appropriate position and screw the threaded ring 54 at its top into the annular threaded groove at the lower end of the auxiliary mounting ring 53 to complete the installation. When the filter cartridge body 45 needs to be installed in different positions, simply turn on the drive motor 55. After the drive motor 55 is turned on, it will automatically drive the limiting plate 51 to rotate. Subsequently, the rotation of the limiting plate 51 will automatically drive the auxiliary support ring on its side to rotate inside the annular groove in the limiting partition 44. The setting of the auxiliary support ring and the annular groove here is related to the limiting plate 51. The rotation of the limiting plate 51 serves as a limiting support. When the limiting plate 51 rotates, it will automatically drive the auxiliary mounting ring 53 at its bottom to rotate. After the auxiliary mounting ring 53 rotates to the appropriate position, the drive motor 55 can be turned off. It should be noted that the drive motor 55 has a self-locking function. After it is turned off, the auxiliary mounting ring 53 can still maintain its position after rotation. At the same time, the drive motor 55 needs to be a drive motor 55 with its own controller. The rotation stroke distance of the drive motor 55 can be controlled by setting the controller parameters, so as to ensure that the auxiliary mounting ring 53 can be adjusted to the appropriate installation position when the limiting plate 51 rotates.

[0027] The pre-dust removal mechanism 6 includes a filter plate 61, a limiting T-block 62, and a support spring 63. The filter plate 61 is slidably installed on the inner side wall of the air inlet pipe 46. The bottom outer wall and top outer wall of the filter plate 61 are symmetrically provided with limiting T-blocks 62. The bottom inner wall and top outer wall of the air inlet pipe 46 are respectively provided with limiting T-grooves for sliding installation of the limiting T-blocks 62. The connection between the outer side wall of the limiting T-block 62 and the inner bottom wall of the limiting T-groove is secure. Equipped with a support spring 63, a miscellaneous storage box 64 is fitted to the bottom outer wall of the air inlet pipe 46, and a positioning mounting strip 65 is symmetrically arranged on the side outer wall of the miscellaneous storage box 64 at the top position. A bracket 66 for the positioning mounting strip 65 to be inserted and installed is symmetrically arranged on the bottom outer wall of the air inlet pipe 46. The bracket 66 is set in an "L" shape, and a square through groove that communicates with the miscellaneous storage box 64 is opened through the bottom outer wall of the air inlet pipe 46 at the side position of the filter plate 61.

[0028] When dust-laden air enters the air inlet duct 46, the filter plate 61 can isolate larger dust particles on its side. Once the outer wall of the filter plate 61 becomes clogged with dust particles, the pressure difference between the low-pressure space inside the protective casing 1 and the external air area will automatically pull the filter plate 61 towards the protective casing 1. This movement of the filter plate 61 will then automatically cause the limiting T-block 62 to slide within the limiting T-groove. At this time, the supporting spring 63 is compressed by the limiting T-block 62. When a significant reduction in airflow is observed on the side of the exhaust pipe 43, it indicates that the filter plate 61 is clogged, and the negative pressure fan 42 is immediately shut off. Consequently, the air pressure difference inside the chamber changes, and the reaction force generated by the compression of the aforementioned support spring 63 quickly causes the filter plate 61 to spring back and reset. Through this vibration process, the impurities accumulated on the outside of the filter plate 61 are automatically shaken off and fall into the storage box 64 through the square groove on its side for centralized collection. When it is necessary to remove the storage box 64 from the device, simply pull the handle on the side of the storage box 64 to remove it from the device horizontally. During installation, simply adjust the storage box 64 to a suitable position and push the positioning mounting strip 65 on its side into the bracket 66. Then, the locking action between the bracket 66 and the positioning mounting strip 65, along with the contact friction, can securely position the storage box 64 inside the device.

[0029] When using this invention, if the entire control device needs to be turned on for dust removal, the negative pressure fan 42 must first be turned on. Once the negative pressure fan 42 is turned on, a low-pressure area will automatically form inside the protective outer casing 1. Then, dusty air will automatically enter the protective outer casing 1 through the air inlet pipe 46. The dirty air entering the protective outer casing 1 first contacts the outer wall of the filter cartridge body 45. After being filtered by the outside of the filter cartridge body 45, the polluted air enters the cartridge and rises, then is discharged to the outside of the device through the exhaust pipe 43. Particulate matter is captured by the filter media on the outside of the filter cartridge body 45, while clean air flows out through the inner wall of the filter cartridge. This process can effectively capture and remove solid particles in the air. The collection box 47 is set up to collect dust and impurities that have accumulated and fallen on the outside of the filter cartridge body 45, while the feed hopper is set up to guide and collect impurities in a concentrated manner. The pulse valve assembly set on the top of the filter cartridge body 45 can be installed on the top of the filter cartridge body 45 using the existing component structure. It is an existing technical means and has not been optimized or improved, so it will not be described in detail here.

[0030] When the filter cartridge body 45 needs to be installed below the limiting plate 51, simply adjust the filter cartridge body 45 to the appropriate position and screw the threaded ring 54 at its top into the annular threaded groove at the lower end of the auxiliary mounting ring 53 to complete the installation. When the filter cartridge body 45 needs to be installed in different positions, simply turn on the drive motor 55. After the drive motor 55 is turned on, it will automatically drive the limiting plate 51 to rotate. Subsequently, the rotation of the limiting plate 51 will automatically drive the auxiliary support ring on its side to rotate inside the annular groove in the limiting partition 44. The setting of the auxiliary support ring and the annular groove here is related to the limiting plate. The rotation of 51 serves as a limiting support. When the limiting plate 51 rotates, it automatically drives the auxiliary mounting ring 53 at its bottom to rotate. Once the auxiliary mounting ring 53 has rotated to the appropriate position, the drive motor 55 can be turned off. Note that the drive motor 55 has a self-locking function; after being turned off, the auxiliary mounting ring 53 will remain in its rotated position. The drive motor 55 must be a drive motor with its own controller. The rotational stroke of the drive motor 55 can be controlled by setting the controller parameters, thus ensuring that the auxiliary mounting ring 53 can be adjusted to the appropriate installation position when the limiting plate 51 rotates.

[0031] When dust-laden air enters the air inlet duct 46, the filter plate 61 can isolate larger dust particles on its side. Once the outer wall of the filter plate 61 becomes clogged with dust particles, the pressure difference between the low-pressure space inside the protective casing 1 and the external air area will automatically pull the filter plate 61 towards the protective casing 1. This movement of the filter plate 61 will then automatically cause the limiting T-block 62 to slide within the limiting T-groove. At this time, the supporting spring 63 is compressed by the limiting T-block 62. When a significant reduction in airflow is observed on the side of the exhaust pipe 43, it indicates that the filter plate 61 is clogged, and the negative pressure fan 42 is immediately shut off. Consequently, the air pressure difference inside the chamber changes, and the reaction force generated by the compression of the aforementioned support spring 63 quickly causes the filter plate 61 to spring back and reset. Through this vibration process, the impurities accumulated on the outside of the filter plate 61 are automatically shaken off and fall into the storage box 64 through the square groove on its side for centralized collection. When it is necessary to remove the storage box 64 from the device, simply pull the handle on the side of the storage box 64 to remove it from the device horizontally. During installation, simply adjust the storage box 64 to a suitable position and push the positioning mounting strip 65 on its side into the bracket 66. Then, the locking action between the bracket 66 and the positioning mounting strip 65, along with the contact friction, can securely position the storage box 64 inside the device.

[0032] It should be noted that the negative pressure fan 42 and drive motor 55 can be powered by existing operating techniques, whether by using a power supply unit or by an external wire. These are all conventional operating techniques and will not be described in detail here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
