Description

Technical Field

[0001] The invention relates to the field of bag dust collectors, in particular to a flower plate supporting structure of a bag dust collector and an installation method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the in-depth development of ultra-low emission work in the environmental protection industry, the application and improvement of dust removal technology has also received more attention. Bag dust collector, as a widely used smoke treatment technology, can be used in conjunction with wet desulfurization, semi-dry desulfurization and denitrification to make the treated industrial flue gas meet the requirements of ultra-low emission. Therefore, it is very necessary and urgent to improve the design level of bag dust collector devices, reduce construction difficulty and improve installation accuracy.

[0004] A very important component of the bag dust collector is the flower plate, which can be called the core component of the bag dust collector. It can serve as a partition between the clean air chamber and the filter chamber of the dust collector, can be used to hang the filter bag assembly, and will also serve as a maintenance platform for the filter bag assembly of the dust collector. The quality of its design, manufacturing and installation is directly related to the performance and service life of the bag dust collector.

[0005] The pattern plate (patterned steel plate) must bear the negative pressure of the system as well as the weight of the filter bag, dust layer and bag cage. The lower part of the pattern plate should be strengthened during design, and the support of the pattern plate should be accurately and firmly positioned. If the pattern plate is deformed, it may affect the weight and verticality of the filter bag and the sealing effect at the bag mouth, causing the dust bag to fall off or leak through the gaps. These will cause dust to be discharged through the chimney, resulting in serious consequences such as substandard smoke at the discharge port. Therefore, the requirements for the support structure of the pattern plate are relatively high. A certain strength must be ensured, and the pattern plate must be accurately positioned. The existing support structure uses frame beams and rib plates to support the pattern plate, which has the problem of poor stability at the joints of the beams, and the beams used to support the pattern plate are prone to shaking.

[0006] In addition, if the structure of the joint is more complicated, there is also the problem of greater difficulty in welding; and the large amount of welding leads to higher construction costs. Summary of the invention

[0042] As introduced in the background technology, the flower plate support structure in the prior art has the problem of poor connection stability at the nodes. In order to solve the above technical problem, the present invention proposes a flower plate support structure for a bag filter.

[0043] Embodiment 1

[0044] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a pattern plate support structure of a bag filter includes a frame beam 1, which is connected to a patterned steel plate support beam 7. The patterned steel plate support beam 7 is a cross beam. A connecting piece 11 is arranged on the bottom side of the frame beam 1, and a supporting column 12 is arranged at the center of the connecting piece. The supporting column 12 supports the cross position of the patterned steel plate support beam 7, and supports the patterned steel plate 3 through the top of the frame beam 1 and the patterned steel plate support beam. A supporting member is arranged at the connection node between the frame beam and the patterned steel plate support beam 7, and the supporting member supports the end of the patterned steel plate support beam from the bottom of the patterned steel plate support beam. A limiting member 2 is arranged on one side of the frame beam toward the supporting member. The limiting member 2 is located on both sides of the end of the patterned steel plate support beam and contacts with the side of the patterned steel plate support beam to play a limiting role.

[0045] In this embodiment, the frame beam 1 is an I-beam; a connecting member 11 is arranged between the frame beam 1 and the supporting column at the bottom thereof, and the connecting member 11 is arranged horizontally. The connecting member can specifically be a connecting frame or a hollow steel plate. The connecting member can be a cross-shaped steel plate, which corresponds to the position of the patterned steel plate support beam. The patterned steel plate support beam 7 is on the top, and the connecting member 11 is arranged at the bottom. A support column 12 is arranged in the center of the cross-shaped steel plate, and the center position of the patterned steel plate support beam 7 is supported by the support column 12.

[0046] refer to Figure 2 and Figure 4 As shown, the supporting member includes a support plate 6, which is arranged on the side of the frame beam facing the patterned steel plate support beam, and the inner side of the support plate 6 is welded to the frame beam. The support plate is specifically a flat plate, and the length of the flat plate is greater than the width of the patterned steel plate support beam 7. In order to ensure stable support for the patterned steel plate support beam, the upper and lower sides of the support plate need to be welded to the web of the frame beam, and the support plate is arranged beyond the bottom side wing plate of the frame beam. The distance between the support plate 6 and the upper flange of the frame beam is adapted to the height of the patterned steel plate support beam. Specifically, the distance between the support plate 6 and the top of the frame beam 1 is less than the height of the patterned steel plate support beam, so that when the patterned steel plate support beam 7 is supported by the support plate, the top can be flush with the upper flange of the frame beam.

[0047] In addition, the support plate 6 supports the blocking plate 9, the upper side of the blocking plate 9 is welded to the top side of the frame beam 1, the lower side of the blocking plate is vertically welded to the support plate 6, the blocking plate 9 is connected to the limit member 2, the limit member is a limit plate, the distance between the two limit plates is adapted to the width of the patterned steel plate support beam 7, the blocking plate 9 and the limit member 2 can be welded and connected in advance, which is convenient for on-site installation. The setting of the blocking plate 9 is used to position the patterned steel plate support beam, and the setting of the blocking plate 9 is also convenient for the setting of the limit member; the spacing distance between the end of the patterned steel plate support beam 7 and the blocking plate is set.

[0048] In order to improve the supporting strength of the support plate 6, the supporting member is connected with a lower rib plate 5 below the support plate 6 to support the support plate. The lower rib plate 5 can be provided at one or more locations. The lower rib plate 5 is vertically connected to the support plate 6. The lower rib plate 5 is welded to the web of the frame beam 1. The lower rib plate and the support plate 6 can be welded in advance. In this way, when connecting on site, only the support plate, the lower rib plate and the frame beam 1 need to be welded, which is convenient for on-site welding operations.

[0049] It should be noted that the limit member 2 is vertically arranged on the support plate 6, and the limit member 2 is vertically connected to the sealing plate 9. The bottom of the limit member 2 can be welded to the support plate 6, or the bottom of the limit member 2 is set at a distance from the support plate. In this way, the side of the patterned steel plate support beam of the limit member limits the patterned steel plate support beam without being fixedly connected to the support plate 6.

[0050] In this embodiment, the patterned steel plate support beam 7 is a cross beam, and the patterned steel plate support beam 7 includes two channel steels arranged opposite to each other, and the height of the channel steel is less than the height of the frame beam 1. Figure 3 and Figure 5 As shown, two channel steels are assembled and welded into a patterned steel plate support beam. Lateral ribs 8 are respectively arranged on both sides of the patterned steel plate support beam 7 to enhance the strength. The lateral ribs 8 can be arranged in multiple layers. Each lateral rib 8 is a steel plate, and both sides of the steel plate are bent to connect with the patterned steel plate support beam.

[0051] refer to Figure 1 As shown, a plurality of support rings 4 are provided on the side of the patterned steel plate support beam, the height of the support ring 4 is less than the height of the patterned steel plate support beam 7, the support rings are arranged along the circumferential direction of the patterned steel plate, the support rings connect the two sides of the patterned steel plate support beam, along the circumferential direction of the patterned steel plate 3, four arc-shaped support steel plates are located on the same circle to form the side wall of the support ring 4, the support ring 4 is provided in multiple places, the bottoms of some support rings are connected, and the height of some support rings is less than the height of other support rings.

[0052] A method for installing a flower plate of a bag dust collector, using the above-mentioned flower plate supporting structure of a bag dust collector, includes the following contents:

[0053] Install the frame beam 1, set a connector 11 at the bottom of the frame beam, set a support column 12 at the center of the connector, and support column 12 supports the cross position of the patterned steel plate support beam 7;

[0054] The support plate 6 is connected to the lower rib plate 5 in advance, and the blocking plate 9 is welded to the limiter 2 in advance;

[0055] A support plate 6 is welded at the connection node between the frame beam 1 and the patterned steel plate support beam 7, and a blocking plate 9 is supported by the support plate. The upper side of the blocking plate is welded to the upper flange of the frame beam, and the lower side is welded to the support plate 6, so that a recess is formed between the blocking plate 9, the support plate 6 and the limit members 2 on both sides;

[0056] The patterned steel plate support beam 7 is assembled and welded through the support column, the end of the patterned steel plate support beam 7 is inserted into the recess, and the end of the patterned steel plate support beam is limited by the limiting member 2, and the top side of the patterned steel plate support beam 7 is flush with the top of the frame beam 1.

[0057] In the support structure provided by the present embodiment, the frame beam supports the patterned steel plate support beam, and the top of the frame beam cooperates with the patterned steel plate support beam to support the patterned steel plate. In order to achieve the stability of the connection between the patterned steel plate support beam and the frame beam at the connection node, a supporting member is arranged at the frame beam, and the supporting member supports the end of the patterned steel plate support beam. A limiting piece is arranged at the frame beam, and the limiting piece is located on both sides of the end of the patterned steel plate support beam. In this way, in conjunction with the supporting member at the bottom, the end of the patterned steel plate support beam is inserted into the recess formed by the limiting piece and the supporting member, which is convenient for quickly positioning the patterned steel plate support beam, not only ensuring the stable support of the patterned steel plate support beam, but also limiting the patterned steel plate support beam from both sides to avoid the problem of shaking of the patterned steel plate support beam.

[0058] Embodiment 2

[0059] The difference between this embodiment and the first embodiment is that:

[0060] refer to Figure 6 , Figure 7 and Figure 8 As shown, the supporting member is an L-shaped supporting angle steel 10, the length of the L-shaped supporting angle steel 10 is greater than the width of the patterned steel plate supporting beam 7, the open side of the L-shaped supporting angle steel 10 is arranged toward the bottom of the frame beam and the lower side of the web of the frame beam, one side of the L-shaped supporting angle steel 10 is connected to the web of the frame beam, and the other side is connected to the bottom of the frame beam. Because one side of the L-shaped supporting angle steel is welded to the bottom of the frame beam, the welding is located on the outside of the frame beam for easy construction.

[0061] The limit piece 2 is located on the upper surface of the L-shaped support angle steel 10. The limit piece 2 is welded to the frame beam 1 or the L-shaped support angle steel 10 to ensure the stability of the limit piece setting. A notch is cut on the upper side of the end of the patterned steel plate support beam 7 so that the end of the patterned steel plate support beam 7 can be inserted into the recess formed by the frame beam and the limit piece 2, so that the patterned steel plate support beam 7 can be inserted between the two limit pieces 2.

[0062] It is easy to understand that in this solution, the limit member 2 is a limit plate, which can be welded to the L-shaped support angle steel 10 in advance to facilitate on-site welding, and the height of the patterned steel plate support beam is adapted to the distance between the L-shaped support angle steel and the upper flange of the frame beam 1, which facilitates the connection between the patterned steel plate support beam and the upper flange of the frame beam 1, avoids the weld being located on the upper surface of the patterned steel plate support beam, and ensures the flatness of the patterned steel plate.

[0063] The supporting member provided in this embodiment has a simple structure and is convenient for welding, thereby effectively reducing the amount of welding and lowering the welding cost.

[0064] A method for installing a flower plate of a bag dust collector, using the flower plate supporting structure of the bag dust collector, includes the following contents:

[0065] Install the frame beam 1, set a connector 11 at the bottom of the frame beam, set a support column 12 at the center of the connector, and support the cross position of the patterned steel plate support beam;

[0066] The L-shaped support angle steel 10 is welded and connected to the limiter 2 in advance;

[0067] An L-shaped supporting angle steel 10 is welded at the connection node between the frame beam 1 and the patterned steel plate support beam 7. The limiting piece 2 and the web of the frame beam 1 can be welded or not connected, because the limiting piece mainly plays a limiting role, and the limiting piece has been connected to the L-shaped supporting angle steel 10, so the limiting piece and the frame beam can be connected without welding, which greatly reduces the welding workload. The patterned steel plate support beam is installed through the support column, and a notch is cut on the upper side of the end of the patterned steel plate support beam 7 so that the end of the patterned steel plate support beam is inserted between the two limiting pieces 2, and the top of the patterned steel plate support beam is flush with the top of the frame beam 1. One end of the patterned steel plate support beam 7 is inserted between the two limiting pieces 2 of the frame beam, and the end of the patterned steel plate support beam is limited by the limiting piece. The patterned steel plate support beam 7 and the upper flange of the frame beam 1 can be welded and connected, and it needs to be smoothed after welding. Because the bottom is supported by the L-shaped supporting angle steel 10, the patterned steel plate support beam 7 and the upper flange of the frame beam 1 do not need to be welded.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
