Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a low-temperature SCR denitrification catalyst forming and drying device. Background Technology

[0002] Low-temperature SCR denitration catalysts play a crucial role in the environmental protection field. As a core component in the denitration reaction, their performance and quality have a decisive impact on denitration efficiency and environmental protection effects. Especially in the catalyst preparation process, the molding and drying stages are key steps to ensure catalyst performance stability and extend service life. However, existing catalyst molding and drying technologies and equipment are gradually revealing significant limitations when processing low-temperature SCR denitration catalysts.

[0003] Specifically, utility model patent CN113405332B discloses a low-temperature SCR denitration catalyst forming and drying device. This device belongs to the field of catalyst processing technology. Through the combined action of a placement rack, conversion chamber, guide surface, receiving plate, adjusting block, eccentric wheel assembly, and area detection assembly, it achieves targeted forming and drying treatment of honeycomb catalysts, effectively improving processing efficiency. However, in practical applications, this device still has some obvious shortcomings.

[0004] First, the device's mounting rack is quite long, making it relatively difficult to retrieve during operation. This is especially problematic when frequent catalyst changes or adjustments are needed; the length not only increases operational complexity but also reduces efficiency. Second, the device lacks dedicated retrieval tools, forcing operators to use both hands or other auxiliary tools, which not only increases operational difficulty but also potentially poses a safety hazard.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a low-temperature SCR denitrification catalyst molding and drying device. This device should optimize the design of the placement rack for easy access and operation, and be equipped with dedicated handling tools to significantly improve operational efficiency and safety. Utility Model Content

[0006] The purpose of this invention is to provide a low-temperature SCR denitrification catalyst forming and drying device, which solves the problem that the existing technology has a long placement rack, which makes it relatively difficult to take the placement rack out during operation.

[0007] To achieve the above objectives, this utility model provides a low-temperature SCR denitrification catalyst forming and drying device, including a drying chamber and several support frames;

[0008] Each of the aforementioned support frames is connected to a number of support frames at its top, and each of the aforementioned support frames is provided with a placement rack at its top;

[0009] An extraction frame is provided on one side of the drying chamber, and two extraction rods are symmetrically arranged on one side of the extraction frame. The two extraction rods are movably connected to one side of the extraction frame through a synchronous moving component. A handle is connected to the top of the extraction frame.

[0010] Both sides of the placement frame are fixedly connected to the center of the docking sleeve.

[0011] The placement rack has several placement slots at one end and several through slots at the top that penetrate the rack and communicate with the placement slots.

[0012] The placement frame has a limiting groove adapted to the extraction rod at the center of both sides and on the inner wall of the docking sleeve.

[0013] The support frame is fixedly connected to the inner wall of the drying chamber, and the support frame is fixedly connected to the top of the support frame with bolts.

[0014] The handle is T-shaped, and one end of the vertical section of the handle is fixedly connected to the top of the extraction frame.

[0015] The extraction frame has a groove on one side, and the synchronous moving component includes a bidirectional screw installed inside the groove. One end of the extraction rod is slidably connected to the inside of the groove, and both ends of the bidirectional screw are threaded through the extraction rod. One end of the bidirectional screw is rotatably connected to the inner wall of the extraction frame, and the other end is rotatably connected to a handle through the side wall of the extraction frame.

[0016] This invention relates to a low-temperature SCR denitrification catalyst forming and drying device.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Example 1

[0026] Please see Figure 1-5 As shown, a low-temperature SCR denitrification catalyst forming and drying device of this embodiment includes a drying chamber 1 and several support frames 5; several support frames 4 are connected to the top of each support frame 5, and a placement rack 3 is provided on the top of each support frame 4; an extraction frame 2 is provided on one side of the drying chamber 1, and two extraction rods 6 are symmetrically arranged on one side of the extraction frame 2. The two extraction rods 6 are movably connected to one side of the extraction frame 2 through a synchronous moving component, and a handle 8 is connected to the top of the extraction frame 2; docking sleeves 9 are fixedly connected to the center of both sides of the placement rack 3.

[0027] First, the catalyst is placed on a support frame 5 inside the drying chamber 1. Specifically, the catalyst is placed on a placement rack 3 within several support frames 4 connected to the top of each support frame 5. This design allows the catalyst to be placed in an orderly and stable manner, facilitating subsequent drying processes.

[0028] When it is necessary to remove or replace the catalyst on the placement rack 3, the operator first picks up the extraction frame 2 using the handle 8. The design of the extraction frame 2 allows it to be easily held and moved by the operator. Next, the operator aligns the two extraction rods 6 on one side of the extraction frame 2 with the inside of the docking sleeves 9 fixedly connected to the center of both sides of the placement rack 3. This step ensures that the extraction rods 6 can be accurately connected to the placement rack 3, preparing for subsequent extraction operations.

[0029] Subsequently, the operator uses the synchronous moving component to bring the two extraction rods 6 closer together, clamping the sides of the placement frame 3. This clamping action ensures a stable connection between the extraction rods 6 and the placement frame 3, preventing the placement frame 3 from slipping or shaking during the extraction process.

[0030] Finally, the operator pulls handle 8 forcefully, causing the extraction rod 6 to contact the inner top of the docking sleeve 9. Since the extraction rod 6 and the placement rack 3 are stably connected via a clamping action, this pulling action easily lifts the placement rack 3. This allows the operator to conveniently remove or replace the placement rack 3 and the catalyst on it from the drying chamber 1.

[0031] Example 2

[0032] Please see Figure 1-5 As shown in this embodiment, a low-temperature SCR denitrification catalyst forming and drying device has several placement slots 12 at one end of a placement rack 3, and several through slots 11 penetrating the placement rack 3 and communicating with the placement slots 12 at the top. Specifically, the catalyst can be placed in the placement slots 12 in an orderly manner. At the same time, the design of the through slots 11 allows for better flow of gas or heat during the drying process, ensuring uniform drying of the catalyst. This design not only improves the placement stability of the catalyst but also optimizes the drying effect, enabling the catalyst to dry more uniformly and efficiently.

[0033] The support frame 5 is fixedly connected to the inner wall of the drying chamber 1, and the support frame 4 is bolted to the top of the support frame 5. Specifically, the fixed connection between the support frame 5 and the support frame 4 ensures the stability of the entire placement system, preventing the catalyst from shifting due to external factors during the drying process. This fixed connection design improves the overall stability of the device, guarantees the drying effect of the catalyst, and facilitates the maintenance and disassembly of the device.

[0034] Example 3

[0035] Please see Figure 1-5As shown in this embodiment, a low-temperature SCR denitrification catalyst forming and drying device has limiting grooves 10 at the center of both sides of the placement frame 3 and on the inner wall of the docking sleeve 9, which are adapted to the extraction rod 6. Specifically, when the extraction rod 6 is inserted into the docking sleeve 9, the limiting grooves 10 ensure that the extraction rod 6 can be accurately and stably positioned on both sides of the placement frame 3, providing support for the clamping action. The design of the limiting grooves 10 enhances the connection stability between the extraction rod 6 and the placement frame 3, prevents the placement frame 3 from slipping or shaking during the extraction process, and improves the safety of operation.

[0036] The handle 8 is T-shaped, with one end of its vertical section fixedly connected to the top of the extraction frame 2. Specifically, the T-shaped handle 8 design makes it easier for operators to grip and move the extraction frame 2, improving operational convenience. The T-shaped handle 8 not only provides a better grip but also reduces hand fatigue during operation, thus improving work efficiency.

[0037] A groove 7 is provided on one side of the extraction frame 2. The synchronous movement component includes a bidirectional screw 13 disposed inside the groove 7. One end of the extraction rod 6 is slidably connected to the inside of the groove 7. Both ends of the bidirectional screw 13 are threaded through the extraction rod 6. One end of the bidirectional screw 13 is rotatably connected to the inner wall of the extraction frame 2, and the other end is rotatably connected to a handle 14 through the side wall of the extraction frame 2. Specifically, the operator drives the bidirectional screw 13 to rotate by rotating the handle 14, thereby causing the two extraction rods 6 to move simultaneously and equidistantly within the groove 7, achieving the clamping or releasing of the placement rack 3. This synchronous movement component design enables precise control of the extraction rods 6, improves the accuracy and efficiency of operation, and reduces the labor intensity of the operator.

[0038] This solution includes the following workflow:

[0039] First, the catalyst is placed systematically on support racks 5 within the drying chamber 1. Specifically, each support rack 5 has several support frames 4 connected to its top, and each support frame 4 has a placement rack 3 on its top. The catalyst is placed in several placement slots 12 opened at one end of the placement rack 3, a design that ensures stable placement of the catalyst. Simultaneously, the top of the placement rack 3 also has several through slots 11 that penetrate the placement rack 3 and communicate with the placement slots 12, allowing for better flow of gas or heat during the drying process and ensuring uniform drying of the catalyst.

[0040] When it is necessary to remove or replace the catalyst on the placement rack 3, the operator first picks up the extraction frame 2 using the T-shaped handle 8. The design of the T-shaped handle 8 not only provides a better grip but also makes it easier for the operator to move the extraction frame 2, improving operational convenience and reducing hand fatigue. Next, the operator aligns the two extraction rods 6 on one side of the extraction frame 2 with the inside of the docking sleeves 9, which are fixedly connected to the center of both sides of the placement rack 3. During this process, the limiting grooves 10 located on the inner wall of the docking sleeves 9 ensure that the extraction rods 6 can be accurately and stably positioned on both sides of the placement rack 3, providing support for the subsequent clamping action.

[0041] Subsequently, the operator uses the synchronous movement component to bring the two extraction rods 6 closer together, clamping both sides of the placement frame 3. The synchronous movement component consists of a bidirectional screw 13 located inside the slide groove 7. One end of the extraction rod 6 is slidably connected to the inside of the slide groove 7, while both ends of the bidirectional screw 13 are threaded through the extraction rod 6. The operator only needs to turn the handle 14 to drive the bidirectional screw 13 to rotate, thereby causing the two extraction rods 6 to move simultaneously and equidistantly within the slide groove 7, achieving the clamping or releasing of the placement frame 3. This clamping action ensures a stable connection between the extraction rods 6 and the placement frame 3, preventing the placement frame 3 from slipping or shaking during extraction.

[0042] Finally, the operator pulls handle 8 forcefully, causing the extraction rod 6 to contact the inner top of the docking sleeve 9. Since the extraction rod 6 and the placement rack 3 are stably connected via a clamping action, this pulling action easily lifts the placement rack 3. This allows the operator to conveniently remove or replace the placement rack 3 and the catalyst on it from the drying chamber 1.

[0043] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
