Description

Technical Field

[0001] This utility model relates to the field of dust collector filter cartridge technology, and more specifically, to a dust collector filter cartridge structure with a flow guiding structure. Background Technology

[0002] Dust collector filter cartridges are the core filtration elements in industrial dust removal systems, efficiently capturing dust particles through mechanisms such as physical interception, inertial collision, and diffusion deposition.

[0003] Currently, dust collector filter cartridges used in dust removal equipment are equipped with flow guiding structures to improve dust removal efficiency. However, common flow guiding structures can only guide the air inlet of the dust collector filter cartridge, but cannot guide the air inside the dust collector filter cartridge, resulting in poor flow guiding effect. For example, the dust collector filter cartridge and dust removal device disclosed in publication number CN217795155U include a filter body with an inner cavity for gas flow. One end of the filter body is provided with an air outlet communicating with the inner cavity, and the other end of the filter body is a closed end. A flow guiding body is disposed in the inner cavity. A flow dividing block is disposed on the end of the flow guiding body near the air outlet. The flow dividing block is provided with a flow dividing surface, and the flow dividing surface is inclined relative to the direction from the air outlet to the closed end.

[0004] As can be seen from the above-disclosed scheme, the dust collector filter cartridge guides the incoming air through the set diversion block. However, the first diversion part of the diversion block guides the air to the side of the air inlet end of the filter body, while the interior of the filter body at the end away from the air inlet cannot be guided, thereby reducing the guiding effect and thus reducing the dust removal effect. In addition, only one diversion block is set, and its height position cannot be adjusted, resulting in poor flexibility of use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dust collector filter cartridge structure with a flow guiding structure. This dust collector filter cartridge structure with a flow guiding structure can segment and guide the gas when air enters downward through the air inlet by setting a first flow dividing plate, a second flow dividing plate, a third flow dividing plate, and a bottom flow dividing plate, which effectively improves the flow guiding effect and thus improves the dust removal effect of the dust collector filter cartridge. Furthermore, the setting of support columns and through holes in each flow dividing plate facilitates the adjustment of the included angle and spacing between the first flow dividing plate, the second flow dividing plate, the third flow dividing plate, and the bottom flow dividing plate according to actual needs, thereby improving the flexibility of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A dust collector filter cartridge structure with a flow guiding structure includes a dust collector filter cartridge body, the dust collector filter cartridge body including a filter element, one end of the filter element being fixedly connected to a first top plate, the first top plate having an air inlet at its center, the other end of the filter element being fixedly connected to a second top plate, the center of the second top plate being detachably connected to a flow guiding mechanism, the flow guiding mechanism including a first diverter plate, a second diverter plate, a third diverter plate, and a bottom diverter plate, the center of the first diverter plate, the second diverter plate, the third diverter plate, and the bottom diverter plate being movably connected to a support column. This dust collector filter cartridge structure with a flow guiding structure, through the first diverter plate, the second diverter plate, the third diverter plate, and the bottom diverter plate, can segment and guide the gas when it enters downwards through the air inlet, effectively improving the flow guiding effect, thereby improving the dust collection effect of the dust collector filter cartridge. Furthermore, through the support column and the through holes in each diverter plate, it is convenient to adjust the angle and spacing between the first diverter plate, the second diverter plate, the third diverter plate, and the bottom diverter plate according to actual needs, improving the flexibility of use.

[0008] Furthermore, the top of the first diverter plate, the second diverter plate, the third diverter plate, and the bottom diverter plate are all provided with a first guide surface and a second guide surface. The first guide surface is an arc-shaped surface, and the second guide surface is a plane. The first guide surface and the second guide surface can segment the air entering the filter element downwards.

[0009] Furthermore, the first, second, third, and bottom flow dividers each have a through hole at their center. The inner wall of the through hole is threaded and is threaded to the surface of the support column, allowing the spacing between the first, second, third, and bottom flow dividers to be adjusted vertically, and the included angle to be adjusted by rotation.

[0010] Furthermore, the surface of the support column is threadedly connected to a limiting sleeve, the center of which is provided with a threaded hole, and the surface of the support column is provided with an external thread. The upper and lower surfaces of each diverter plate are pressed against the end faces of the two limiting sleeves, and the positioning stability is ensured by the limiting sleeves.

[0011] Furthermore, a limiting ring and a connecting sleeve are fixedly connected to the surface of the second top plate. The limiting ring and the second top plate enclose an installation groove, and the inner wall of the installation groove is fixed to one end of the filter element, which has the function of limiting the position.

[0012] Furthermore, a screw is fixedly connected to one end of the limiting sleeve, and an anti-slip sleeve is fixedly fitted onto the surface of the screw. The screw is threadedly connected to the fastening groove, which facilitates the disassembly and assembly of the support column.

[0013] Furthermore, one end of the connecting sleeve has a fastening groove, and the inner wall of the fastening groove is provided with internal threads.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This scheme can segment the gas flow when the air enters downward through the first diversion plate, the second diversion plate, the third diversion plate and the bottom diversion plate, which can effectively improve the diversion effect and thus improve the dust removal effect of the dust removal filter cartridge.

[0016] (2) This solution, through the support columns and through holes in each diverter plate, facilitates the adjustment of the angle and spacing between the first diverter plate, the second diverter plate, the third diverter plate and the bottom diverter plate according to actual needs, thus improving the flexibility of use.

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1-5 A dust collector filter cartridge structure with a flow guiding structure includes a dust collector filter cartridge body 1, which includes a filter element 11. The filter element 11 is made of folded filter paper or filter cotton and is used to filter air. Its composition and working principle are well known to those skilled in the art. One end of the filter element 11 is fixedly connected to a first top plate 12. The bottom of the first top plate 12 is provided with a groove of the same size as the mounting groove 16, which facilitates quick positioning of the upper end of the filter element 11 and fixation of the end face of the filter element 11. An air inlet 13 is opened at the center of the first top plate 12. The other end of the filter element 11 is fixedly connected to a second top plate 14. A limiting ring 15 and a connecting sleeve 17 are fixedly connected to the surface of the second top plate 14. The limiting ring 15 and the second top plate 14 are engaged. The filter element 11 is surrounded by an installation groove 16. The inner wall of the installation groove 16 is fixed to one end of the filter element 11, which has a limiting function. The center of the second top plate 14 is detachably connected to a flow guiding mechanism 2. The flow guiding mechanism 2 includes a first flow dividing plate 3, a second flow dividing plate 4, a third flow dividing plate 5, and a bottom flow dividing plate 6. The top of the first flow dividing plate 3, the second flow dividing plate 4, the third flow dividing plate 5, and the bottom flow dividing plate 6 are all provided with a first flow guiding surface 32 and a second flow guiding surface 33. The first flow guiding surface 32 is an arc-shaped surface, and the second flow guiding surface 33 is a plane. The first flow guiding surface 32 and the second flow guiding surface 33 can segment the air entering the filter element 11 downwards. The center of the first flow dividing plate 3, the second flow dividing plate 4, the third flow dividing plate 5, and the bottom flow dividing plate 6 is movably connected to a support column 7.

[0027] The first diverter plate 3, the second diverter plate 4, the third diverter plate 5, and the bottom diverter plate 6 each have a through hole 31 at their center. The inner wall of the through hole 31 is provided with an internal thread, and the inner wall of the through hole 31 is threadedly connected to the surface of the support column 7. This allows the spacing between the first diverter plate 3, the second diverter plate 4, the third diverter plate 5, and the bottom diverter plate 6 to be adjusted vertically, and the included angle to be adjusted by rotation. The surface of the support column 7 is threadedly connected to a limit sleeve 73, which has a threaded hole at its center. The surface of the support column 7 is provided with an external thread. The upper and lower surfaces of each diverter plate are pressed against the end faces of the two limit sleeves 73, and the positioning stability is ensured by the limit sleeves 73.

[0028] One end of the limiting sleeve 73 is fixedly connected to a screw 72, and an anti-slip sleeve 71 is fixedly sleeved on the surface of the screw 72. The screw 72 is threadedly connected to the fastening groove 18, which facilitates the disassembly and assembly of the support column 7. One end of the connecting sleeve 17 has a fastening groove 18, and the inner wall of the fastening groove 18 is provided with internal threads.

[0029] In use, the dust collector filter cartridge structure with a flow guiding structure allows external air to enter the filter element 11 vertically downwards through the air inlet 13. After the air enters the filter element 11 through the air inlet 13, a portion of the air first contacts the first diverter plate 3, causing a portion of the air to flow towards the inner wall of the filter element 11 for filtration. Then, the air continues to move downwards and sequentially contacts and guides the air entering the filter element 11 through the second diverter plate 4, the third diverter plate 5, and the bottom diverter plate 6 from top to bottom. This allows the air entering the filter element 11 to be guided in segments, thereby ensuring full utilization of the filtration surface within the filter element 11. When installing the flow guiding mechanism 2, the first diverter plate 3, the second diverter plate 4, the third diverter plate 5, and the bottom diverter plate 6 can be adjusted according to actual needs. The positions and rotation angles of the flow plate 4, the third flow plate 5, and the bottom flow plate 6 on the support column 7 can be adjusted. After adjustment, they can be clamped by the limiting sleeve 73. When the first flow plate 3, the second flow plate 4, the third flow plate 5, and the bottom flow plate 6 are set to intake air downwards through the air inlet 13, the gas can be guided in segments, which effectively improves the guiding effect and thus improves the dust removal effect of the dust collector filter cartridge. Furthermore, the support column 7 and the through holes 31 set in each flow plate make it easy to adjust the included angle and spacing between the first flow plate 3, the second flow plate 4, the third flow plate 5, and the bottom flow plate 6 according to actual needs, which improves the flexibility of use.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
