Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of kiln tail dust collectors, and particularly relates to the anti-damage structure of the inlet and outlet end plates of a kiln tail dust collector with reinforcing ribs. Background Technology
[0002] As a key environmental protection device in cement production lines, the kiln tail dust collector is subjected to harsh conditions such as high negative pressure, dust-laden airflow, and intermittent corrosive gases for a long time. This makes it a high-risk area for damage and air leakage. Most existing inlet and outlet end plates are single steel plate structures, and the basic rigidity is insufficient to withstand the high negative pressure load inside the dust collector, making them prone to local inward deformation. Long-term deformation can lead to cracking of the end plate welds or damage to the body, resulting in air leakage. This not only reduces dust removal efficiency but also increases system energy consumption, requiring frequent shutdowns for repair welding and maintenance. Utility Model Content
[0003] This utility model addresses the problems in the prior art by proposing the following technical solution: This utility model provides a damage-resistant structure for the inlet and outlet end plates of a kiln tail dust collector with reinforcing ribs, including: A reinforcing plate, wherein an upper rib group and a lower rib group are provided protruding from one end face of the reinforcing plate, and the upper rib group and the lower rib group each include a number of ribs extending along the width direction of the reinforcing plate and arranged at intervals along the length direction of the reinforcing plate; A wear-resistant connector includes a connecting cover with a slot inside. During assembly, the reinforcing plates are spliced together, and the lower rib group of the upper reinforcing plate and the upper rib group of the lower reinforcing plate are inserted into the slot of the connecting cover. The connecting cover is also provided with a locking structure to lock the connecting cover and each reinforcing plate.
[0004] As a preferred embodiment of the above technical solution, the locking structure includes connecting plates symmetrically arranged at both ends of the connecting cover, wherein the connecting plates are tightly fitted with the corresponding reinforcing plates and are fitted with locking bolts.
[0005] As a preferred embodiment of the above technical solution, the wear-resistant connector further includes a plurality of reinforcing ribs spaced apart, the reinforcing ribs being disposed on the end of the connecting cover away from the reinforcing plate.
[0006] As a preferred embodiment of the above technical solution, the reinforcing rib extends along the length direction of the reinforcing plate.
[0007] As a preferred embodiment of the above technical solution, the outer layer of the wear-resistant connector away from the reinforcing plate is coated with a wear-resistant layer.
[0008] The beneficial effects of this utility model are as follows: This utility model can weld and cover the vulnerable areas of the original end plate by setting a reinforcing plate. Its protruding upper and lower ribs can greatly improve the bending stiffness of the reinforcing plate itself, effectively resist the high negative pressure load inside the dust collector, prevent the reinforcing plate from sinking under stress alone, and provide sufficient support for the original end plate. This fundamentally avoids deformation, weld cracking or body damage of the original end plate due to insufficient rigidity, thereby reducing air leakage, ensuring stable dust removal efficiency and reducing system energy consumption. Meanwhile, the connecting cover of the wear-resistant connector uses a slot to precisely insert the ribs of adjacent reinforcing plates, ensuring that the overall surface is flat and gap-free after splicing to avoid air leakage, and forming a surface contact stress structure to evenly distribute the high negative pressure concentrated load to the ribs and connecting cover, avoiding stress concentration and damage at the splice. Combined with the locking structure of the connecting cover, it can ensure that the splice is firm and does not loosen under high negative pressure and dust impact conditions.

[0010] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0011] Example like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of a single reinforcing plate in an embodiment; Figure 2 The diagram shown is a side view of a single reinforcing plate in an embodiment; This device includes: The reinforcing plate 10 has an upper rib group 11 and a lower rib group 12 protruding from one end face. Both the upper rib group 11 and the lower rib group 12 include a number of ribs that extend along the width direction of the reinforcing plate 10 and are spaced apart along the length direction of the reinforcing plate 10.
[0012] The reinforcing plate 10 serves as the main structure for preventing damage to the inlet and outlet end plates of the kiln tail dust collector. It is used to weld and cover a local area of the original end plate (focusing on the reverse side of the raw material mill) to provide sufficient basic rigidity, prevent the original end plate from deforming due to insufficient rigidity, and reduce the risk of air leakage from the source.
[0013] Specifically, such as Figure 1 As shown in the coordinate system, the X direction indicates the length direction of the reinforcing plate 10, and the Y direction indicates the width direction of the reinforcing plate 10.
[0014] The upper rib group 11 and the lower rib group 12 can enhance the bending stiffness of the reinforcing plate 10 itself and prevent the reinforcing plate 10 from denting inward due to high negative pressure when it is subjected to force alone.
[0015] On the other hand, it also provides a positioning and support carrier for splicing adjacent reinforcing plates 10.
[0016] like Figure 3 As shown, Figure 3 The diagram shown is a side view of the overall structure in the embodiment; It also includes a wear-resistant connector 20, which is detachably connected to the adjacent reinforcing plate 10.
[0017] The wear-resistant connector 20 enables the detachable splicing of adjacent reinforcing plates 10, allowing for flexible splicing of different numbers of reinforcing plates 10 to cover the required area.
[0018] like Figure 4 , Figure 5 As shown, Figure 4 The diagram shown is a front view of the overall structure in the embodiment; Figure 5 What is shown is Figure 3 A schematic diagram of a partial cross-sectional structure in the diagram; The wear-resistant connector 20 includes a connecting cover 21, which has a slot inside. During assembly, the upper and lower reinforcing plates 10 are spliced together. The lower rib group 12 of the upper reinforcing plate 10 and the upper rib group 11 of the lower reinforcing plate 10 are inserted into the slot of the connecting cover 21. The connecting cover 21 is also provided with a locking structure to lock the connecting cover 21 and each reinforcing plate 10.
[0019] The connecting cover 21 can accurately position the adjacent reinforcing plates 10, ensuring that the whole is flat after splicing. After accurate positioning, the ribs and the slots fit together completely, forming surface contact force, which evenly distributes the load generated by the high negative pressure to the two sets of ribs and the connecting cover 21, greatly reducing local stress and preventing the structure from being damaged due to stress concentration.
[0020] The locking structure includes connecting plates 22 symmetrically arranged at both ends of the connecting cover 21. The connecting plates 22 are tightly attached to the corresponding reinforcing plates 10 and are fitted with locking bolts 23.
[0021] The connecting plate 22 and the reinforcing plate 10 are further secured by the locking bolts 23, achieving a detachable fit. Specifically, the connecting plate 22 has a through hole that matches the specifications of the locking bolts 23, and a threaded hole is pre-set on the connecting plate 22 corresponding to this hole position, ensuring that the locking bolts 23 can be fully tightened, and multiple sets of locking bolts 23 are provided.
[0022] The wear-resistant connector 20 also includes a number of reinforcing ribs 24 spaced apart. The reinforcing ribs 24 are disposed on the end of the connecting cover 21 away from the reinforcing plate 10 and extend along the length of the reinforcing plate 10.
[0023] The reinforcing rib 24 enhances the overall rigidity of the wear-resistant connector 20, preventing it from deforming under high negative pressure or dust impact, and avoiding air leakage due to cracking of the splice seam caused by deformation of the wear-resistant connector 20; at the same time, it shares the load borne by the connecting cover 21, extends the service life of the wear-resistant connector 20, and reduces the need for frequent maintenance after intermediate repairs.
[0024] The wear-resistant connector 20 has an outer layer coated with a wear-resistant layer.
[0025] The wear-resistant layer is applied to the outer layer of the wear-resistant connector 20 away from the reinforcing plate 10, directly contacting the dust-laden airflow inside the dust collector. Specifically, the wear-resistant layer can be a ceramic particle-reinforced resin-based coating. This coating uses epoxy resin or modified phenolic resin as the binder matrix, with silicon carbide or alumina ceramic particles uniformly dispersed inside. It is cured on the outer layer of the wear-resistant connector 20 by scraping or high-pressure spraying, and can directly resist the high-speed scouring of the dust-laden airflow (such as airflow carrying raw or cooked material particles) inside the dust collector.
[0026] Working principle: This structure is fixedly welded to the inner side of the inlet and outlet end plate of the kiln tail dust collector. The spliced reinforcing plates 10 cover part of the original end plate, directly improving the local foundation rigidity of the original end plate and preventing deformation of the original end plate due to the high negative pressure inside the dust collector. This prevents the end plate from cracking and leaking due to deformation at the source. Before the overall structure is welded and fixed, adjacent reinforcing plates 10 are spliced together by wear-resistant connectors 20. The slot of the connecting cover 21 accurately positions the lower rib group 12 of the upper reinforcing plate 10 and the upper rib group 11 of the lower reinforcing plate 10, forming a surface contact force-bearing structure. This structure can evenly distribute the concentrated load generated by the high negative pressure to the two rib groups and the connecting cover 21, avoiding damage due to stress concentration at the splice, while ensuring the overall flatness after splicing and preventing air leakage at the splice seam.
[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
