Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a bottom-mounted vertical filter cartridge dust collector. Background Technology

[0002] Currently, commonly used dust collectors in industry are generally divided into bag filters and cartridge filters. Bag filters are popular and widely used due to their simple structure and wide range of applications. However, due to the limitation of the filter bag's filtration area, they are not suitable for installation in some confined spaces. Therefore, people have attempted to improve the above-mentioned technical solutions, leading to the development of side-mounted cartridge filters. Each group of filter cartridges in a side-mounted cartridge filter is equipped with a separate soot blowing device. When the dust collector is larger, the number of soot blowing devices also increases, as does the operating time of the soot blowing devices; the increased number of soot blowing devices also increases the potential for failure. This increases both manufacturing costs and potential failure points, as well as the operating time and energy consumption of the soot blowing devices. To address this, a bottom-mounted vertical cartridge filter was proposed. Utility Model Content

[0003] Therefore, it is necessary to provide a bottom-mounted vertical cartridge dust collector to address the aforementioned technical problems.

[0004] To address the aforementioned technical problems, this utility model provides a solution through the following technical solution: In side-mounted cartridge dust collectors, each set of filter cartridges requires a separate soot blowing device. When the dust collector is large, the number of soot blowing devices increases, as does the operating time of these devices. This increase in the number of soot blowing devices also increases the potential for failure. This not only increases manufacturing costs and the number of potential failures, but also increases the operating time and energy consumption of the soot blowing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bottom-mounted vertical cartridge dust collector includes: a dust collection box, a first inspection door fixedly connected to the top of the dust collection box, a first inspection door sealed at the top of the dust collection box, a fixing structure for installation inside the dust collection box, multiple filter cartridges inside the dust collection box, an installation structure for connecting upper and lower filter cartridges, a second inspection door hinged to one side of the dust collection box, an air inlet pipe at the top of the dust collection box, an air outlet pipe on one side of the air inlet pipe, a dust collection hopper fixedly connected to the bottom of the air inlet pipe, a dust discharge valve fixedly connected to the bottom of the dust collection hopper, an air blowing structure for cleaning inside the air inlet pipe, and an air guiding mechanism for collection inside the air inlet pipe.

[0006] As a preferred embodiment of the bottom-mounted vertical cartridge dust collector provided by this utility model, the fixing structure includes multiple support frames, which are fixedly installed inside the dust collection box. Multiple positioning steels are fixedly arranged on both sides of the inside of the dust collection box. One end of the support frame is fastened inside the positioning steel. Multiple fixing rods are fixedly connected inside the support frame, and the filter cartridge is installed on the outside of the fixing rods.

[0007] In a preferred embodiment of the bottom-mounted vertical filter cartridge dust collector provided by this utility model, the cross-section of the positioning steel is machined into a U-shape, and the support frame is fastened inside the positioning steel.

[0008] As a preferred embodiment of the bottom-mounted vertical filter cartridge dust collector provided by this utility model, the installation structure includes a filter cartridge positioning ring, which is located between two filter cartridges, and the filter cartridge is fastened inside the filter cartridge positioning ring.

[0009] In a preferred embodiment of the bottom-mounted vertical filter cartridge dust collector provided by this utility model, grooves are provided on both the upper and lower sides of the filter cartridge positioning ring, and one end of the filter cartridge is inserted into the groove.

[0010] As a preferred embodiment of the bottom-mounted vertical filter cartridge dust collector provided by this utility model, the air blowing structure includes a pulse dust collector, which is fixedly installed inside the dust collection box and located below the filter cartridge.

[0011] As a preferred embodiment of the bottom-mounted vertical filter cartridge dust collector provided by this utility model, the air guiding mechanism includes multiple air boxes, which are installed inside the dust collection box and located below the filter cartridge.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves improvements through the coordinated design of a bottom-mounted vertical filter cartridge, a pulse dust collector arranged below, and an air box guide. During the dust removal stage, the pulse dust collector releases high-pressure pulse gas from the bottom of the filter cartridge. After the dust is dislodged by the vibration, it falls directly into the dust collection hopper below under the guidance of gravity and the air box, without having to pass through other filter cartridges, thus completely avoiding the problem of "dust re-attaching to the filter cartridge". The air box adopts a steel plate bending structure. The top annular steel plate is fitted with the filter cartridge and is internally connected. It can guide the pulse gas to evenly cover each set of filter cartridges, ensuring that dust on the surface of the filter cartridges is removed without dead corners. This solves the problem of reduced dust removal efficiency caused by "airflow carrying dust back to the filter cartridges after baffle accumulation" in existing technologies.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0017] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A bottom-mounted vertical cartridge dust collector includes: a dust collection box 14, with a first inspection door 2 fixedly connected to the top of the dust collection box 14, the first inspection door 2 being sealed at the top of the dust collection box 14, a fixing structure for installation inside the dust collection box 14, multiple filter cartridges 6 inside the dust collection box 14, a connecting installation structure between upper and lower filter cartridges 6, a second inspection door 7 hinged to one side of the dust collection box 14, an air inlet pipe 1 at the top of the dust collection box 14, an air outlet pipe 8 on one side of the air inlet pipe 1, a dust collection hopper 10 fixedly connected to the bottom of the air inlet pipe 1, a dust discharge valve 9 fixedly connected to the bottom of the dust collection hopper 10, an air blowing structure for cleaning inside the air inlet pipe 1, and an air guide mechanism for collection inside the air inlet pipe 1. During installation, firstly, positioning steel 4 is fixed to both sides of the inner wall of the dust collection box 14, then one end of the support frame 3 is snapped into the positioning steel 4 to form a stable support frame; subsequently, fixing rod 5... The filter cartridge 6 is fixed inside the support frame 3, and finally the filter cartridge 6 is fitted onto the outside of the fixing rod 5. The three work together to achieve vertical fixation of the filter cartridge 6 in the dust collector 14, so as to prevent the filter cartridge 6 from shifting due to airflow impact or dust cleaning vibration.

[0018] Preferably, the fixing structure includes multiple support frames 3, which are fixedly installed inside the dust collector 14. Multiple positioning steels 4 are fixedly installed on both sides of the inside of the dust collector 14. One end of the support frame 3 is fastened inside the positioning steel 4. Multiple fixing rods 5 are fixedly connected inside the support frame 3, and the filter cartridge 6 is installed on the outside of the fixing rods 5. The positioning steel 4 has a U-shaped cross-section, and the support frame 3 is fastened inside the positioning steel 4. The U-shaped cross-section of the positioning steel 4 forms a groove structure. When installing the support frame 3, the end of the support frame 3 is directly inserted into the U-shaped groove. The two side walls of the groove provide lateral restraint for the support frame 3, preventing it from swaying left and right inside the dust collector 14. The U-shaped opening direction is adapted to the installation requirements of the support frame 3, requiring no additional bolts for precise alignment, and allowing for quick fastening / disassembly. Preferably, the installation structure includes a filter cartridge positioning ring 12, which is located between two upper and lower filter cartridges 6. The filter cartridges 6 are fastened inside the filter cartridge positioning ring 12. When multiple sets of vertically arranged filter cartridges 6 are installed in the dust collector 14, the filter cartridge positioning ring 12 is placed at the joint of the upper and lower filter cartridges 6, and the upper and lower filter cartridges 6 are fastened into the filter cartridge positioning ring 12 respectively. By matching the center hole of the filter cartridge positioning ring 12 with the outer diameter of the filter cartridge 6, it is ensured that the upper and lower filter cartridges 6 are in the same vertical line, avoiding airflow short circuit (unfiltered airflow passing through the gap) due to misalignment.

[0019] Preferably, the filter cartridge positioning ring 12 has grooves on both the upper and lower sides. One end of the filter cartridge 6 is inserted into the groove. The grooves on the upper and lower sides of the filter cartridge positioning ring 12 are precisely matched with the shape of the end of the filter cartridge 6. During installation, the end of the filter cartridge 6 is inserted into the groove. The depth and inner diameter of the groove restrict the radial movement of the filter cartridge 6 and prevent gaps between the upper and lower filter cartridges 6. The groove can also guide the installation direction of the filter cartridge 6, eliminating the need for repeated position adjustments.

[0020] Preferably, the air blowing structure includes a pulse dust collector 11, which is fixedly installed inside the dust collection box 14 and located below the filter cartridge 6. During the dust removal stage, the pulse dust collector 11 (located below the filter cartridge 6) receives a signal and releases high-pressure pulse gas. The gas acts on the bottom end face of the filter cartridge 6 from bottom to top, and the dust on the outer surface of the filter cartridge 6 is removed by impact and vibration. After the dust is removed, it falls directly into the dust collection hopper 10 under the action of gravity without passing through other filter cartridges 6.

[0021] Preferably, the air guiding mechanism includes multiple air boxes 13, which are installed inside the dust collection box 14 and located below the filter cartridges 6. During the filtration stage, the air boxes 13 are connected to the inside of the filter cartridges 6, and the clean airflow discharged from multiple sets of filter cartridges 6 is collected and guided to the outlet pipe 8 to avoid airflow turbulence leading to pressure loss. During the dust removal stage, the air boxes 13 guide the high-pressure gas of the pulse dust collector 11 to be evenly distributed to the bottom of each filter cartridge 6, and at the same time guide the detached dust to the dust collection hopper 10 to reduce the accumulation of dust on the inner wall of the dust collection box 14.

[0022] The usage process of the bottom-mounted vertical cartridge dust collector provided by this utility model is as follows: Dust collector box sealing and airflow introduction: The dust collector box 14 serves as the outer shell of the device, providing installation and sealing working space for all internal components; the first inspection door 2, which is sealed on the top, and the second inspection door 7, which is hinged on one side, are both closed to ensure that there is no dust leakage inside the box; the dust-laden airflow enters the box evenly through the air inlet end of the dust collector box 14 (adapted to airflow introduction requirements), and the airflow guidance is initially completed.

[0023] Filter cartridge fixing and airflow filtration: The fixing structure inside the dust collector 14 (support frame 3, positioning steel 4, fixing rod 5) first vertically fixes the filter cartridge 6—the positioning steel 4 is fixed to both sides of the inner wall of the dust collector 14, one end of the support frame 3 is snapped into the positioning steel 4 to form a stable frame, and the filter cartridge 6 is fitted on the outside of the fixing rod 5 inside the support frame 3; at the same time, the upper and lower filter cartridges 6 are positioned by the filter cartridge positioning rings 12 (the upper and lower side grooves are adapted to the ends of the filter cartridges 6) to prevent the filter cartridges 6 from being misaligned; when the dust-laden airflow flows through the filter cartridge 6, the filter material of the filter cartridge 6 intercepts the dust (the dust is adsorbed on the outer surface), the clean airflow passes through the inside of the filter cartridge 6, and then is discharged through the exhaust pipe 8 on one side of the dust collector 14.

[0024] Pulse cleaning and airflow guidance: When the dust on the surface of the filter cartridge 6 accumulates to a set amount, the pulse dust collector 11 located below the filter cartridge 6 in the dust collection box 14 is activated; the pulse dust collector 11 releases high-pressure pulse gas, which acts on the bottom of the filter cartridge 6 from bottom to top, and the dust is removed by airflow vibration; at the same time, the air box 13 in the dust collection box 14 (located below the filter cartridge 6) guides the pulse gas to evenly cover each group of filter cartridges 6, avoids airflow dispersion, and guides the removed dust to the dust collection hopper 10 below, preventing the dust from being raised in the box and re-attaching to the filter cartridge 6.

[0025] Dust collection and unloading: Dust detached from filter cartridge 6 falls into dust collection hopper 10 fixedly connected to the bottom of dust collector 14 under the action of gravity and air guide of air box 13. Dust collection hopper 10 temporarily stores dust. When the dust in dust collection hopper 10 reaches the capacity threshold, the unloading valve 9 fixedly connected to its bottom is opened to discharge the dust from the device, completing a single dust removal cycle. If filter cartridge 6 needs maintenance, the first inspection door 2 (top) or the second inspection door 7 (side) can be opened for convenient inspection / replacement of filter cartridge 6.
