TECHNICAL FIELD

[0001] The application relates to the technical field of flue gas filtration, in particular to a 304 stainless steel dust removal framework for flue gas filtration. BACKGROUND

[0002] The dust removal framework is an essential accessory of a bag-type dust remover and is used as a frame for supporting dust removal filter bags. The dust removal filter bags are usually in a cylindrical shape and are vertically hung in the dust remover. The dust removal framework can prevent the dust removal filter bags from collapsing and rupturing due to negative pressure during the filtration process, so that the dust removal filter bags can maintain a stable cylindrical shape inside the dust remover, maximize the filtration area, ensure high filtration efficiency, and thus improve the filtration state and service life of the dust removal filter bags.

[0003] According to the search, the patent document with the authorized announcement number CN221964747U announces a dust removal framework for flue gas filtration, which comprises a bottom plate, the left side of the bottom plate is fixedly connected with a support rod, the left side of the support rod is fixedly connected with a connecting plate, the left side of the connecting plate is provided with a gas inlet cover in a penetrating manner, and the surface of the support rod is fixedly connected with an annular bone plate. The cooperation of the bottom plate, the support rod, the connecting plate, the gas inlet cover, the annular bone plate, the base layer, the heat insulation layer, the reinforcing layer, the waterproof layer, the corrosion-resistant layer, the protective layer, the first protective layer and the second protective layer realizes the advantages of impact resistance, corrosion resistance, waterproofness and wear resistance, solves the defects of the previous dust removal framework for flue gas filtration in use, such as the lack of impact resistance structure, which easily causes the damage of the dust removal framework for flue gas filtration in use, and the lack of corrosion resistance, waterproofness and wear resistance, reduces the service life of the dust removal framework for flue gas filtration, and cannot meet the current market demand.

[0004] However, the above scheme still has at least the following disadvantages in actual use: only one size specification of dust removal filter bag can be used, the height of the dust removal framework as a whole cannot be adjusted, and thus the dust removal filter bag installation requirements of different height specifications cannot be met, the universality and adaptability of the dust removal framework are poor, and in addition, the dust removal filter bag will be slightly elongated after long-term use, at which time the dust removal framework cannot effectively support the dust removal filter bag, affecting the use of the dust removal filter bag.

[0005] Therefore, we propose a 304 stainless steel dust removal framework for flue gas filtration to solve the above problems. CONTENT OF THE UTILITY MODEL

[0007] The above-mentioned technical objective of this application is achieved through the following technical solution: a 304 stainless steel dust collector frame for flue gas filtration, comprising an annular connecting plate, a base plate, adjustable support beams and an air inlet hood, wherein the base plate is located directly below the annular connecting plate, and the number of adjustable support beams is set to multiple, wherein the multiple adjustable support beams are all located between the annular connecting plate and the base plate and are distributed in an equally spaced ring, and the air inlet hood is fixedly installed at the bottom of the annular connecting plate and located between the multiple adjustable support beams.

[0008] A further configuration of this application is as follows: the adjustable support beam includes an upper support rod, an upper connecting rod, a lower support rod, a lower connecting rod, and a locking member. The upper support rod is fixedly installed at the bottom of the annular connecting plate, the upper connecting rod is fixedly installed at the bottom end of the upper support rod, the lower support rod is fixedly installed at the top of the base plate, and the lower connecting rod is fixedly installed at one top end of the lower support rod. One side wall of the upper connecting rod is in sliding contact with one side wall of the lower connecting rod. The locking member is disposed between the upper connecting rod and the lower connecting rod and is used to lock and fix the upper connecting rod and the lower connecting rod.

[0009] A further feature of this application is that the upper support rod and the upper connecting rod are integrally cast, and the lower support rod and the lower connecting rod are integrally cast.

[0010] A further provision of this application is that the locking element is a locking bolt, a threaded hole is provided on one side of the upper connecting rod, one end of the locking bolt is threaded through the threaded hole, a threaded groove is provided on one side wall of the lower connecting rod, and one end of the locking bolt is threadedly installed in the threaded groove.

[0016] This application includes at least one of the following beneficial technical effects:

[0017] 1. This application utilizes multiple adjustable support beams arranged in an evenly spaced ring between the annular connecting plate and the bottom plate. Together with the upper annular rib plates fixed on multiple upper support rods, the lower annular rib plates fixed on multiple lower support rods, and the annular ribs fixed on multiple upper connecting rods, they form a three-dimensional support frame. This support frame is the dust collector frame. When the dust collector filter bag is placed on this dust collector frame, the dust collector frame can expand the dust collector filter bag and maintain its shape, preventing the dust collector filter bag from collapsing or breaking during the filtration process. The annular connecting plate and the bottom plate are located at the top and bottom, respectively, and serve to fix the adjustable support beams.

Moreover, when the dust collector filter bag becomes longer after long-term use, the height of the adjustable support beam can be adjusted slightly to ensure that the dust collector frame continues to effectively support the dust collector filter bag.

[0025] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a 304 stainless steel dust collector frame for flue gas filtration, including an annular connecting plate 1, a base plate 2, adjustable support beams 3, and an air inlet hood 4. The base plate 2 is located directly below the annular connecting plate 1. Multiple adjustable support beams 3 are provided, all located between the annular connecting plate 1 and the base plate 2 and distributed in a ring at equal intervals. The air inlet hood 4 is fixedly installed at the bottom of the annular connecting plate 1 and located between the multiple adjustable support beams 3. The adjustable support beams 3 include an upper support rod 31. The system includes an upper connecting rod 32, a lower support rod 33, a lower connecting rod 34, and a locking element. The upper support rod 31 is fixedly installed at the bottom of the annular connecting plate 1, the upper connecting rod 32 is fixedly installed at the bottom end of the upper support rod 31, the lower support rod 33 is fixedly installed at the top of the base plate 2, and the lower connecting rod 34 is fixedly installed at one top end of the lower support rod 33. One side wall of the upper connecting rod 32 is in sliding contact with one side wall of the lower connecting rod 34. The locking element is disposed between the upper connecting rod 32 and the lower connecting rod 34 and is used to lock and fix the upper connecting rod 32 and the lower connecting rod 34. The locking component is a locking bolt 36. A threaded hole 35 is provided on one side of the upper connecting rod 32, and one end of the locking bolt 36 is threaded through the threaded hole 35. A threaded groove 37 is provided on one side wall of the lower connecting rod 34, and one end of the locking bolt 36 is threaded into the threaded groove 37. The number of threaded grooves 37 is set to multiple, and the multiple threaded grooves 37 are evenly distributed. The upper connecting rod 32 and the lower connecting rod 34 of the adjustable support beam 3 slide in contact and are connected and fixed by the locking bolt 36 and the multiple equally distributed threaded grooves 37. This allows the height of the adjustable support beam 3 to be flexibly adjusted according to actual needs. This design can adapt to the installation requirements of dust collector filter bags of different heights and sizes, improve the versatility and adaptability of the dust collector frame, and reduce the cost and inventory pressure of customizing different models of dust collector frames due to differences in dust collector filter bag specifications. Moreover, when the dust collector filter bag becomes longer after long-term use, the height of the adjustable support beam 3 can be adjusted slightly to ensure that the dust collector frame can continue to effectively support the dust collector filter bag.

[0027] In this embodiment, the upper support rod 31 and the upper connecting rod 32 are integrally cast, and the lower support rod 33 and the lower connecting rod 34 are integrally cast. This ensures high connection strength between the upper support rod 31 and the upper connecting rod 32, and also ensures high connection strength between the lower support rod 33 and the lower connecting rod 34, thereby enhancing the strength of the adjustable support beam 3. The upper support rod 31 and the lower support rod 33 have the same width, and the sum of the widths of the upper connecting rod 32 and the lower connecting rod 34 is the same as the width of the lower support rod 33, further enhancing the strength of the adjustable support beam 3.

[0028] In this embodiment, the annular connecting plate 1, base plate 2, upper support rod 31, upper connecting rod 32, lower support rod 33, lower connecting rod 34, locking bolt 36, and air inlet hood 4 are all made of 304 stainless steel. By using 304 stainless steel to make the annular connecting plate 1, base plate 2, upper support rod 31, upper connecting rod 32, lower support rod 33, lower connecting rod 34, locking bolt 36, and air inlet hood 4, it has good corrosion resistance, can adapt to the complex chemical environment of flue gas filtration, effectively extend the service life of the dust collector frame, reduce equipment maintenance costs and replacement frequency, and ensure the long-term stable operation of the flue gas filtration system.

[0029] In this embodiment, upper annular support plates 5 are fixedly installed on multiple upper support rods 31, lower annular support plates 6 are fixedly installed on multiple lower support rods 33, and annular reinforcing bars 7 are fixedly installed on multiple upper connecting rods 32. By utilizing multiple adjustable support vertical beams 3 evenly spaced and distributed in a ring between the annular connecting plate 1 and the bottom plate 2, they cooperate with the upper annular support plates 5, lower annular support plates 6, and annular reinforcing bars 7 to form a stable three-dimensional support structure. This structure can withstand greater external pressure and internal stress, preventing deformation or damage to the dust collector frame due to airflow impact, dust collector filter bag weight, and other factors during flue gas filtration. This ensures that the dust collector filter bag is always in a well-supported state, which is beneficial to improving filtration efficiency and the stability of filtration effect. It should be noted that the upper annular support plates 5, lower annular support plates 6, and annular reinforcing bars 7 are all made of 304 stainless steel.

[0030] With the above structure, the working principle of the 304 stainless steel dust collector frame for flue gas filtration provided in this application is as follows:

[0031] Multiple adjustable support beams 3 are evenly spaced and arranged in a ring between the annular connecting plate 1 and the bottom plate 2. Together with the upper annular bone plates 5 fixed on multiple upper support rods 31, the lower annular bone plates 6 fixed on multiple lower support rods 33, and the annular ribs 7 fixed on multiple upper connecting rods 32, they form a three-dimensional support frame. This support frame is the dust collector frame. When the dust collector filter bag is placed on this dust collector frame, the dust collector frame can expand the dust collector filter bag and keep it in a certain shape, so as to prevent the dust collector filter bag from collapsing or breaking during the filtration process. The annular connecting plate 1 and the bottom plate 2 are located at the top and bottom, respectively, and play the role of fixing the adjustable support beams 3. At the same time, they also provide connection positions for the upper and lower ends of the dust collector filter bag, ensuring that the dust collector filter bag can be firmly installed on the dust collector frame.

[0032] The air intake hood 4 is fixedly installed at the bottom of the annular connecting plate 1 and located between multiple adjustable support vertical beams 3. When the flue gas containing dust enters the air intake hood 4, the flue gas is evenly dispersed into the inside of the dust collector filter bag under the guidance of the air intake hood 4. Because the dust collector filter bag is opened by the dust collector frame, its internal space allows the flue gas to fully contact the inner wall of the dust collector filter bag. Dust particles are blocked by the dust collector filter bag, while the filtered clean gas seeps out through the dust collector filter bag wall, thereby realizing the flue gas filtration process.

[0033] When using this dust collector frame, if it is necessary to adjust the overall height of the dust collector frame, the connection between the upper connecting rod 32 and the lower connecting rod 34 can be released by unscrewing the locking bolt 36 out of the corresponding threaded groove 37. Then, the overall height of the adjustable support beam 3 can be changed by moving the upper connecting rod 32 (or the lower connecting rod 34) up and down. After the adjustable support beam 3 is adjusted to a suitable height, the upper connecting rod 32 and the lower connecting rod 34 can be locked and fixed by threading one end of the locking bolt 36 into the corresponding threaded groove 37, thus determining the height of the adjustable support beam 3. This completes the overall height adjustment of the dust collector frame, which can then adapt to the installation requirements of dust collector filter bags of different heights and sizes, improving the versatility and adaptability of the dust collector frame. Moreover, when the dust collector filter bag becomes longer after long-term use, the height of the adjustable support beam 3 can be adjusted slightly to ensure that the dust collector frame continues to effectively support the dust collector filter bag.
