Description

Technical Field

[0001] This utility model relates to the field of sintering dust removal technology, specifically to a tube sheet structure for a bag filter dust collector. Background Technology

[0002] To reduce dust emission concentration during sintering, dust collection facilities such as bag filters are typically installed outside the sintering fuel system. Bag filters mount filter bags on a flat plate at the top of the dust collector; the plate is typically made of metal or reinforced concrete. Perforations are cut into the plate for mounting the filter bags, thus securing the bags and creating a seal that divides the interior of the bag filter into two parts, allowing air to pass only through the filter bags.

[0003] For example, Chinese patent CN221207196U discloses a tube sheet for a bag filter dust collector. The tube sheet is a concrete slab structure with cooling pipes installed inside to cool the concrete slab. During use, the filter bags are supported by the concrete slab.

[0004] However, when replacing the filter bags after a period of use, fine dust may accumulate on the upper part of the tube sheet, making filter bag replacement more difficult. Furthermore, if the seal between the filter bag and the tube sheet fails during dust collector use, some air may flow to the upper part of the tube sheet without being filtered by the filter bag. If this is not detected in time, it may affect the filtration effect.

[0005] Based on this, the present invention designs a tube sheet structure for a bag filter to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tube sheet structure for a bag filter dust collector.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tube sheet structure for a bag filter dust collector includes a fixing plate and a dust blocking module, and also includes a pressure detection structure;

[0009] A recessed insert plate is fixedly installed on the lower side of the fixed plate. Multiple mounting holes for installing filter bags are evenly spaced in a rectangular array on the fixed plate. Multiple dust-blocking modules are installed on the upper side of the fixed plate. Pressure detection structures are installed on the recessed insert plate and the dust-blocking modules.

[0010] The pressure detection structure includes a first detection structure and a second detection mechanism. The second detection mechanism is installed on the lower side of the sinking plate, and the first detection structure is installed on the lower side of the dust blocking module.

[0011] Furthermore, the first detection structure is identical to the second detection mechanism.

[0012] Furthermore, the fixing plate has a recessed groove for installing the dust-blocking module, and fixing rings are evenly fixed in a rectangular array within the recessed groove; the center of the fixing rings coincides with the center of the mounting hole.

[0013] Furthermore, the dust-blocking module includes a dust-blocking plate, a circular insert plate, and an installation module. A clearance groove is symmetrically provided on both sides of the sinking trough. The sinking trough is inserted into the dust-blocking plate, and a circular insert plate is fixedly installed on the dust-blocking plate in a rectangular array, with the circular insert plate aligned with the mounting hole. A circular groove is provided in a rectangular array at the bottom of the dust-blocking plate; the center of the circular groove coincides with the center of the circular insert plate. The installation module is installed on the dust-blocking plate.

[0014] Furthermore, the installation module includes fixing blocks, which are symmetrically fixedly installed on the dust baffle plate, and a receiving groove is opened on the lower side of the fixing blocks; a first detection structure is installed in the receiving groove.

[0015] Furthermore, the mounting module also includes bosses, which are symmetrically fixedly mounted on the sinking groove, with the bosses aligned with the receiving groove.

[0016] Furthermore, the first detection structure includes a protection module and a detection module, with the protection module installed in the receiving slot and the detection module installed inside the protection module.

[0017] Furthermore, the protective module includes an upper sealing plate, a bellows, a lower sealing plate, an outer sleeve, and an inner sleeve. The upper sealing plate is fixedly installed at the top of the receiving groove. One end of the bellows is fixedly connected to the upper sealing plate, and the lower end of the bellows is fixedly connected to the lower sealing plate. The outer sleeve and the inner sleeve are located inside the bellows. The upper end of the outer sleeve is fixedly connected to the upper sealing plate, and the lower end of the inner sleeve is fixedly connected to the lower sealing plate. The outer sleeve and the inner sleeve are in a limited sliding connection.

[0018] Compared with the prior art, the advantages of this utility model are as follows: The recessed insert plate and fixing plate are placed on the bag filter, and the filter bag is passed through the mounting hole to install it on the upper side of the mounting hole. Then, multiple dust-blocking modules are placed on the upper side of the fixing plate, and the dust-blocking modules press the filter bag tightly, improving the stability of the filter bag installation. Simultaneously, during use, dust in the lower layer of air is blocked by the filter bag, and the air passes through the filter bag and is discharged from the mounting hole to the upper side of the dust-blocking modules. After long-term use, fine dust in the air settles on the dust-blocking modules, thus facilitating filter bag replacement. When needed, the dust-blocking module can be directly moved aside, and then the filter bag can be replaced. Simultaneously, the multiple dust-blocking modules facilitate batch replacement of filter bags in different areas, preventing fine dust from settling on the fixing plate and affecting subsequent filter bag installation. Furthermore, during use, the pressure on the sinking plate is detected by the second detection mechanism, facilitating the assessment of whether the airflow and filtration efficiency match, and enabling timely detection of excessive pressure within the baghouse dust collector. The pressure between the dust-blocking module and the fixing plate is detected by the first detection structure, thus facilitating the determination of any air leakage. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A tube sheet structure for a bag filter dust collector includes a fixing plate 1 and a dust blocking module 2; it also includes a pressure detection structure 3.

[0031] A recessed insert plate 11 is fixedly installed on the lower side of the fixed plate 1. Multiple mounting holes 12 for installing filter bags are evenly spaced in a rectangular array on the fixed plate 1. Multiple dust-blocking modules 2 are installed on the upper side of the fixed plate 1. Pressure detection structures 3 are installed on the recessed insert plate 11 and the dust-blocking modules 2.

[0032] like Figure 2 and Figure 4 As shown, the pressure detection structure 3 includes a first detection structure 31 and a second detection mechanism 32. The second detection mechanism 32 is installed on the lower side of the sinking plate 11, and the first detection structure 31 is installed on the lower side of the dust blocking module 2.

[0033] The first detection structure 31 and the second detection mechanism 32 have the same structure.

[0034] In this embodiment, when the tube sheet structure of the bag filter is working normally, the recessed insert plate 11 and the fixing plate 1 are placed on the bag filter, and the filter bag is passed through the mounting hole 12 to install the filter bag on the upper side of the mounting hole 12. Then, multiple dust-blocking modules 2 are placed on the upper side of the fixing plate 1, and the dust-blocking modules 2 press the filter bag to improve the stability of the filter bag installation. At the same time, during use, after the dust in the lower layer of air is blocked by the filter bag, the air passes through the filter bag and is discharged from the mounting hole 12 to the upper side of the dust-blocking module 2. After long-term use, the fine dust in the air settles on the dust-blocking module 2, thereby improving the stability of the filter bag installation. When replacing the filter bag, the dust-blocking module 2 can be directly moved aside, and then the filter bag can be replaced. At the same time, the setting of multiple dust-blocking modules 2 makes it easy to replace the filter bags in batches in different areas, avoiding the settling of fine dust on the fixing plate 1, which would affect the installation of subsequent filter bags. During use, the pressure on the sinking plate 11 is detected by the second detection mechanism 32, which makes it easy to determine whether the air volume and filtration efficiency are matched, and to detect excessive pressure in the bag filter in time. The pressure between the dust-blocking module 2 and the fixing plate 1 is detected by the first detection structure 31, which makes it easy to determine whether there is any air leakage.

[0035] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 3 As shown, the fixing plate 1 has a recessed groove 14 for installing the dust blocking module 2. Fixing rings 13 are evenly fixed in a rectangular array within the recessed groove 14; the center of the fixing rings 13 coincides with the center of the mounting hole 12.

[0036] like Figures 3-5 As shown, the dust-blocking module 2 includes a dust-blocking plate 21, a circular insert plate 22, and an installation module. A recessed groove 14 has symmetrical clearance grooves 23 on both sides. The recessed groove 14 is inserted into the dust-blocking plate 21. Circular insert plates 22 are fixedly installed on the dust-blocking plate 21 in a rectangular array, with the circular insert plates 22 aligned with the mounting holes 12. A circular groove 24 is formed in a rectangular array at the bottom of the dust-blocking plate 21. The center of the circular groove 24 coincides with the center of the circular insert plate 22. The installation module is installed on the dust-blocking plate 21.

[0037] The mounting module includes a fixing block 25. The fixing blocks 25 are symmetrically fixed on the dust baffle 21. A receiving groove 26 is opened on the lower side of the fixing block 25. A first detection structure 31 is installed in the receiving groove 26.

[0038] The installation module also includes a boss 27. The boss 27 is symmetrically fixedly installed on the recessed groove 14, and the boss 27 is aligned with the receiving groove 26.

[0039] like Figures 4-6 As shown, the first detection structure 31 includes a protection module and a detection module. The protection module is installed in the receiving slot 26, and the detection module is installed in the protection module.

[0040] The protective module includes an upper sealing plate 311, a bellows 312, a lower sealing plate 313, an outer sleeve 314, and an inner sleeve 315. The upper sealing plate 311 is fixedly installed at the top of the receiving groove 26. One end of the bellows 312 is fixedly connected to the upper sealing plate 311, and the lower end of the bellows 312 is fixedly connected to the lower sealing plate 313. The outer sleeve 314 and the inner sleeve 315 are located inside the bellows 312. The upper end of the outer sleeve 314 is fixedly connected to the upper sealing plate 311, and the lower end of the inner sleeve 315 is fixedly connected to the lower sealing plate 313. The outer sleeve 314 and the inner sleeve 315 are in a limited sliding connection.

[0041] The detection module includes a pressure plate 316, a pressure sensor 317, and a spring 318. The pressure plate 316 is fixedly installed on the upper side of the lower sealing plate 313, and the pressure sensor 317 is fixedly installed on the lower side of the upper sealing plate 311. The spring 318 is sleeved on the outside of the outer sleeve 314 and the inner sleeve 315. One end of the spring 318 is fixedly connected to the upper sealing plate 311, and the other end of the spring 318 is fixedly connected to the lower sealing plate 313.

[0042] In this embodiment, when the dust-blocking module 2 and the pressure detection structure 3 are working normally, the filter bag is passed through the mounting hole 12 and installed on the upper side of the mounting hole 12, with the upper side of the filter bag blocked by the fixing ring 13; the dust-blocking plate 21 is placed in the sink trough 14, and the circular insert plate 22 is inserted into the filter bag; when the filter bag needs to be replaced after a period of use, the dust-blocking plate 21 can be easily removed through the clearance groove 23; during use, the lower layer of air passes through the filter bag and then flows to the upper side of the dust-blocking plate 21 through the mounting hole 12 and the circular insert plate 22; during long-term use, fine dust in the air settles on the dust-blocking plate 21; thus, when replacing the filter bag, the dust-blocking plate 21 can be directly removed, and the fixing plate 1 used to install the filter bag is in a clean state, which facilitates the replacement of the filter bag;

[0043] During use, if the filter bag and mounting hole 12 fail to seal, gas will flow through the mounting hole 12 into the space between the sink trough 14 and the dust baffle 21. At this time, the air pressure will push the lower sealing plate 313 to move, causing the bellows 312 to deform. The outer sleeve 314 and the inner sleeve 315 will slide in a limiting manner, causing the pressure plate 316 on the lower sealing plate 313 to press the pressure sensor 317, resulting in a change in the pressure sensor 317 value. This will facilitate the determination of whether there is a leak. At the same time, the pressure status of the lower gas can be determined by the second detection mechanism 32 on the lower side of the sinking insert plate 11.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
