Description

Technical Field

[0001] This utility model relates to the field of denitrification catalyst production technology, and in particular to a green billet stacking rack for SCR denitrification catalyst. Background Technology

[0002] In the production process of SCR denitrification catalysts, the stacking and drying of green billets are crucial steps. Currently, traditional methods of stacking SCR denitrification catalyst green billets have many drawbacks. When multiple layers are stacked, the lower layers inevitably bear the weight of the upper layers, making them highly susceptible to deformation under pressure. Once deformed, the internal pores may become blocked, or the overall shape may become irregular, ultimately rendering these green billets unusable, resulting in wasted raw materials and increased production costs.

[0003] Meanwhile, existing stacking methods mostly involve tightly packing green billets together. This stacking method severely hinders the flow of hot air between the green billets, making the green billet drying process extremely difficult. Hot air cannot evenly contact each green billet, resulting in uneven drying and difficulty in effectively removing internal moisture. This not only reduces drying efficiency and prolongs the production cycle but also adversely affects the final quality of the green billets. Therefore, it is essential to develop a green billet stacking rack for SCR denitrification catalysts that can solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide an SCR denitrification catalyst green compact stacking rack to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A SCR denitrification catalyst green preparation stacking rack includes a base. The base has a main body consisting of columns and beams, and multiple layers of green preparation trays are arranged vertically along the main body. Each green preparation tray includes a tray frame and multiple parallel support rods fixed within the tray frame. The support rods are used to laterally and at intervals support the SCR denitrification catalyst green preparations. Rolling supports are provided on both sides of the tray frame, and slide rails that cooperate with the rolling supports are provided on the beams.

[0007] Furthermore, the cross-section of the support rod is flat on top and round on the bottom. The upper plane of the support rod is used to support the SCR denitration catalyst green body. The upper plane of the support rod provides stable support for the SCR denitration catalyst green body; the rounded structure at the bottom of the support rod reduces weight while ensuring strength.

[0008] Furthermore, multiple U-shaped mounting slots are evenly spaced on the inner side of the pallet frame. The lower arc surface of the support rod mates with the bottom arc surface of the mounting slot.

[0009] Furthermore, the spacing between the support rods is equal, and the spacing size ensures that each SCR denitrification catalyst green body can be supported by at least three support rods.

[0010] Furthermore, the rolling support is a pulley. Casters are installed at the lower end of the base.

[0011] Furthermore, the columns, beams, and green trays are all made of metal and have a rust-proof coating on their surfaces.

[0012] This invention also includes other components that enable the SCR denitrification catalyst green compact stacking rack to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not specified in this invention all employ conventional techniques in the art, such as pulleys and casters mentioned in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0013] The working principle of this invention is as follows: A sliding rail mounted on the crossbeam cooperates with rolling supports on both sides of the green substrate tray, allowing each layer of the green substrate tray to be independently pulled and slid. This design enables the weight of each layer of SCR denitrification catalyst green substrate and its tray to be directly transferred to the uprights via the crossbeam, achieving independent load-bearing for each layer and fundamentally preventing the upper layer from compressing and deforming the lower layer. Simultaneously, the SCR denitrification catalyst green substrates are placed at intervals on the green substrate trays by support rods, forming a three-dimensional ventilation channel that ensures that the drying hot air can evenly and efficiently coat each SCR denitrification catalyst green substrate, thus effectively solving the problem of uneven drying.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Eliminate the risk of green billet extrusion deformation: The weight of the green billet is indirectly transferred to the column through the layered independent load-bearing structure, avoiding the blockage of the duct and shape distortion caused by the lower green billet bearing the load of the upper layer.

[0016] 2. Improved drying efficiency and uniformity: The support rod and green plate tray facilitate air circulation, thereby improving the drying efficiency and uniformity of the SCR denitrification catalyst green plate. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example:

[0023] like Figures 1-3 As shown, an SCR denitrification catalyst green preparation stacking rack includes a base 1. The base 1 has a main body consisting of columns 2 and beams 3, and multiple layers of green preparation trays 5 are arranged vertically along the main body of the stacking rack. Each green preparation tray 5 includes a tray frame 6 and multiple parallel support rods 7 fixed within the tray frame 6. The support rods 7 are used to horizontally and intermittently support the SCR denitrification catalyst green preparations 10.

[0024] In addition, rolling supports, namely pulleys 9, are provided on both sides of the pallet frame 6. A slide rail 4, which mates with the pulleys 9, is provided on the crossbeam 3. Multiple U-shaped mounting slots 8 are evenly spaced on the inner side of the pallet frame 6. The cross-section of the support rod 7 is flat at the top and round at the bottom; the upper plane of the support rod 7 supports the SCR denitrification catalyst green body 10. The lower arc surface of the support rod 7 mates with the bottom arc surface of the mounting slot 8. Casters 11 are installed at the lower end of the base 1.

[0025] Specifically, the spacing between the support rods 7 is equal, and the spacing is such that each SCR denitrification catalyst green body 10 can be supported by at least three support rods 7. The columns 2, beams 3, and green body trays 5 are all made of metal and have a rust-proof coating on their surfaces.

[0026] The working principle of this utility model's SCR denitrification catalyst green body stacking rack is as follows: The slide rail 4 on the crossbeam 3 cooperates with the rolling supports on both sides of the green body tray 5, allowing each layer of green body tray 5 to be independently pulled and slid. This design enables the weight of each layer of SCR denitrification catalyst green body 10 and green body tray 5 to be directly transferred to the column 2 through the crossbeam 3, achieving independent load-bearing for each layer and fundamentally avoiding the compression and deformation of the lower layer by the upper layer of material. Simultaneously, the SCR denitrification catalyst green bodies 10 are placed at intervals on the green body tray 5 by the supporting rods 7, forming a three-dimensional ventilation channel that ensures that the drying hot air can evenly and efficiently coat each SCR denitrification catalyst green body 10, thus effectively solving the problem of uneven drying.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope of the present utility model.
