Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 7As shown, a vertically mounted cartridge dust collector with a drawer includes a housing 1. In this embodiment, a lifting ring 7 is provided on the outer side of the top of the housing 1, which provides convenience for the user. Inside the housing 1, from top to bottom, a fan chamber 10, a back-blowing chamber 11, a cartridge hopper 12, and a dust storage chamber 13 are arranged in sequence. A primary filtration air inlet box 2 is arranged on the outer side of the cartridge hopper 12 and communicates with it. The primary filtration air inlet box 2 includes an air inlet 22, and a flame arrestor is arranged on the inner side of the air inlet 22. In this embodiment, the primary filtration air inlet box 2 includes an air inlet hood 21, and an installation frame 23 is arranged inside the air inlet hood 21. A flame arrestor is installed on the installation frame 23. The flame arrestor can be, but is not limited to, a flame arrestor mesh 20. An electrical control box 102 is installed in the back-blowing chamber 11. Vertically mounted cartridges 3 are arranged in the cartridge hopper 12. A dust storage drawer 5 is slidably connected to the dust storage chamber 13. A centrifugal fan 4 is arranged in the fan chamber 10.

[0026] In operation, dust (possibly containing sporadic sparks) generated in the laser cutting, welding, and grinding dust removal industries is drawn into the primary filter inlet box 2 under the negative pressure generated by the centrifugal fan 4. It then enters the flame arrestor mesh 20 through the inlet 22, where the sparks are extinguished by the impact and larger dust particles are filtered out. The dust then enters the filter cartridge chamber 12, where the increased space reduces the airflow velocity. The airflow is then evenly distributed across the surface of the vertically mounted filter cartridges 3, filtering out micron-sized dust particles. Finally, the clean air passes through the outlet plate 8 of the fan chamber 10 and is discharged into the atmosphere. The dust collected on the surface of the filter cartridges settles into the dust collection drawer 5, which can be easily removed by pulling out the drawer.

[0027] As can be seen, the vertically mounted filter cartridge dust collector with drawer of this utility model can prevent sparks from entering the interior, prevent dust accumulation in the filter cartridge, and prevent dust leakage from the connecting surface. Moreover, this utility model adopts a reasonable overall layout design for dust purification, and is equipped with a primary flame arrestor 20, a secondary vertically mounted filter cartridge 3 for high-efficiency dust removal, and a movable ash storage drawer 5. The high integration of dual-stage filtration can meet the working conditions of the laser cutting, welding, and grinding dust removal industries. The vertically mounted filter cartridge 3 dust collector is plug-and-play, occupies a small area, and is easy to maintain, saving customers space and costs.

[0028] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a first mounting plate 105 is provided between the filter cartridge chamber 12 and the backflush chamber 11 of this utility model. A pressing mechanism 107 is provided on one side of the first mounting plate 105 located in the filter cartridge chamber 12. The pressing mechanism 107 is used to press and fix the top end of the vertically mounted filter cartridge 3, and the bottom end of the vertically mounted filter cartridge 3 is suspended.

[0029] The clamping mechanism 107 used in this embodiment includes two opposing clamping plates. Each clamping plate has a mounting groove on its outer side, which is fixed to a first mounting plate 105. The clamping plates and corresponding mounting grooves are hinged together. An operating handle is provided on the outer side of each clamping plate, allowing the clamping plate to rotate to loosen and clamp the top of the filter cartridge. The clamping mechanism 107 also includes a self-locking structure on the two operating handles. This self-locking structure prevents the clamping plates from rotating arbitrarily, reliably securing the filter cartridge. Furthermore, the clamping mechanism 107 of this invention is easy to operate, allowing for convenient replacement of the filter cartridge.

[0030] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a grid plate is provided between the ash storage chamber 13 and the filter cartridge 12 in this utility model. This grid plate 6 can ensure that the dust falls (collects) into the ash storage drawer 5 and prevent the dust from being raised.

[0031] In this invention, the bottom of the filter cartridge 12 is provided with a guide structure, which surrounds the top of the grid plate. The guide structure is used to guide the dust, facilitating the dust to fall into the dust collection drawer 5. In this embodiment, the guide structure includes at least one guide plate 108, specifically three guide plates 108, each guide plate 108 is inclined from the outside to the inside (from the top to the bottom).

[0032] like Figure 2 As shown, in this embodiment, the ash storage chamber 13 is provided with an ash storage door 101, and an ash storage drawer 5 is provided inside the ash storage door 101. By opening the ash storage door 101, the ash storage drawer 5 can be easily pulled out, and the ash storage door 101 can prevent dust leakage from the connecting flour.

[0033] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the back-blowing chamber 11 of this utility model is equipped with a dust blowing device 109. The dust blowing device 109 includes an air tank 1092, an air outlet pipe 1091 connected to the air tank 1092, a control valve on the air outlet pipe 1091, and an air outlet nozzle 1090 on the air outlet pipe 1091. The air outlet nozzle 1090 is directed towards the filter cartridge chamber 12. The control valve is electrically connected to the electrical control box 102. The electrical control box 102 may be equipped with a pressure transmitter. The pressure difference between the inside and the surface of the filter cartridge can be detected by the pressure transmitter. When the pressure difference reaches a preset value, the control valve opens, allowing the compressed gas in the air tank 1092 to pass through the air outlet pipe 1091 and be blown away from the air outlet nozzle 1090, thus removing the dust from the surface of the filter cartridge.

[0034] In this embodiment, a mounting bracket 1093 is provided on one side of the first mounting plate 105 located in the backflush chamber 11, and an air tank 1092 is mounted on the mounting bracket 1093. All air outlet pipes 1091 are located on both sides of the air tank 1092. In this embodiment, the soot blowing device 109 includes four air outlet pipes 1091, and each air outlet pipe 1091 has an air outlet nozzle 1090 at its end, so that the four air outlet nozzles 1090 can be matched one-to-one with the four vertical filter cartridges 3 to better remove dust from the surface of the vertical filter cartridges 3; and / or, an oil-water separator 103 is provided on the outside of the backflush chamber 11, and the oil-water separator 103 is connected to the air tank 1092 through a pipe to separate water vapor in the air tank 1092. In addition, an electrical box 104 is also provided on the outside of this utility model, see [link to related documentation]. Figure 2 In actual use, the present invention can be powered by connecting to the electrical box 104.

[0035] like Figure 4 As shown, a second mounting plate 106 is provided between the backflush chamber 11 and the fan chamber 10, and a mounting through hole is provided in the middle of the second mounting plate 106; the centrifugal fan 4 is located at the mounting through hole, and an air outlet plate 8 is provided at the top of the fan chamber 10.

[0036] like Figure 2 As shown, a filter cartridge inspection plate 9 is provided on the side of the filter cartridge compartment 12, and a fan inspection plate 100 is provided on the side of the fan room 10. Maintenance and management can be conveniently carried out through the inspection plates.

[0037] In summary, the vertically mounted filter cartridge dust collector with drawer of this utility model has a primary filtration air inlet box 2 (with built-in flame arrestor 20) that can filter larger dust particles and prevent sparking dust particles from entering the dust collector. The secondary vertically mounted filter cartridge 3 provides high-efficiency filtration, filtering micron-sized dust particles and preventing dust accumulation on the filter cartridge. The vertically mounted filter cartridge 3 is also easy to inspect and replace. The dust collector has a movable ash storage drawer 5 at the bottom, eliminating the need for on-site assembly and preventing dust leakage due to improper assembly. The integrated structure effectively solves the problems of sporadic sparks entering the equipment from dust, easy dust accumulation on the top of the filter cartridge leading to fire, dust leakage during assembly and connection, and inconvenience in inspecting and replacing the filter cartridge.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications or improvements to the same type of vertically mounted filter cartridge dust collector with drawer made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
