Description

Technical Field

[0001] The utility model relates to the technical field of catalyst particle processing bins, in particular to a waste SCR denitration catalyst particle processing bin. Background Art

[0002] In existing SCR (Selective Catalytic Reduction) denitrification technology, catalyst particles gradually lose their activity over time, becoming spent SCR denitrification catalyst particles. Due to differences in composition, activity, and physical form, these spent catalyst particles often need to be sorted and stored for subsequent recycling or safe disposal. However, most of the spent SCR denitrification catalyst particle processing bins currently available on the market are simple in design and have a single function, primarily focusing on the collection and temporary storage of spent catalyst particles, while lacking effective means for their sorting and storage.

[0003] Specifically, existing processing bins typically have only one storage area, making it difficult to carefully sort spent catalyst particles by size. This design flaw leads to the mixing of spent catalyst particles during storage, increasing the difficulty and cost of subsequent recycling and potentially causing secondary environmental pollution due to improper handling.

It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A waste SCR denitrification catalyst particle processing bin includes a first bin body 1, the bottom end of the first bin body 1 is connected to a second bin body 2, and the bottom end of the second bin body 2 is connected to a third bin body 3, a top cover 6 is movably installed on the top of the first bin body 1, and a feed pipe 8 is provided on the top outer surface of the top cover 6, a motor 7 is fixedly installed on the top outer surface of the top cover 6, and the bottom end of the motor 7 is connected to a coupling 711, one end of the coupling 711 is connected to a shaft 712, and two groups of filter screens 713 are fixedly installed on the outer surface of the shaft 712, and a discharge pipe 9 is provided on the outer surface of one side of the first bin body 1, the second bin body 2 and the third bin body 3.

[0026] Furthermore, the inner walls of the first bin body 1 and the second bin body 2 are fixedly installed with a limit ring 714, and the limit ring 714 is located at the bottom end of the filter screen 713. The limit ring 714 can effectively prevent the filter screen 713 from shifting or falling off during rotation, thereby ensuring the stable operation of the equipment and the accuracy of particle screening.

[0027] Furthermore, multiple groups of support rods 4 are fixedly installed at the bottom end of the third bin body 3, and reinforcement rods 5 are fixedly installed between the multiple groups of support rods 4. The multiple groups of support rods 4 and reinforcement rods 5 enhance the load-bearing capacity and stability of the entire processing bin, preventing structural deformation or damage due to particle accumulation or improper operation.

[0028] Furthermore, one end of the discharge pipe 9 is connected to a flange 911, which makes the connection with the external pipeline more flexible and convenient, facilitates the transportation and discharge of particles, and also facilitates the maintenance and inspection of the equipment.

[0029] Furthermore, an electronic valve 912 is provided on the outer surface of the discharge pipe 9. The electronic valve 912 realizes precise control of particle emission and can open or close the discharge pipe at any time as needed, thereby improving the operability and flexibility of the equipment.

[0030] Furthermore, an inspection port 211 is provided on one side outer surface of the first bin body 1, the second bin body 2 and the third bin body 3. The inspection port 211 provides convenience for the internal maintenance and inspection of the equipment. Maintenance personnel can enter the interior of the bin through these inspection ports to inspect, clean or replace components such as the filter screen and the shaft rod.

[0031] Furthermore, two groups of limit plates 214 are fixedly installed on the inner wall of the top of the inspection port 211, and multiple groups of electric push rods 213 are arranged between the two groups of limit plates 214, and one end of the multiple groups of electric push rods 213 is connected to a movable door 212. The limit plates 214 provide stable support and limiting effects for the movable door, and the electric push rods 213 realize the automatic opening and closing of the movable door, reducing the workload of maintenance personnel.

[0032] Working Principle: First, spent SCR denitration catalyst particles are fed into the first bin 1 through the feed pipe 8. At this stage, the motor 7 is activated, and its power is transmitted to the shaft 712 via the coupling 711, causing the shaft 712 to begin rotating. Two sets of filter screens 713 are fixedly mounted on the outer surface of the shaft 712. These filter screens 713 rotate with the shaft 712, dynamically filtering and screening the spent catalyst particles entering the first bin 1.

[0033] Thanks to the rationally designed pore size of the filter 713, particles can be effectively separated by size. Larger particles or impurities are blocked by the filter 713 within the first bin 1, while smaller particles continue to fall through the pores of the filter 713. To prevent the filter 713 from shifting or being damaged during rotation, limit rings 714 are fixedly mounted on the inner walls of both the first bin 1 and the second bin 2. These limit rings 714 provide stable support and a position-limiting effect for the filter 713. The smaller particles filtered through the first bin 1 then fall through the opening at the bottom of the first bin 1 into the second bin 2. Within the second bin 2, a rotating filter 713 (here, the second set of filters 713) is also installed, which further separates the particles. Because the filter 713 in the second bin 2 has a finer pore size, it can further separate even finer particles. The particles filtered through the second bin 2 continue to fall into the third bin 3.

[0034] The third bin 3 serves as the final collection area, storing fine particles after the two-stage screening process. These particles remain within the third bin 3 for subsequent recycling or processing. To ensure the stability and load-bearing capacity of the processing bin, multiple sets of support rods 4 are fixedly mounted at the bottom of the third bin 3, with reinforcement rods 5 fixed between them.

[0035] When it is necessary to discharge the particles in a certain bin, this can be achieved by opening the electronic valve 912 on the corresponding discharge pipe 9. One end of the discharge pipe 9 is connected to an external pipeline through a flange 911 to facilitate the transportation and discharge of particles.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
