Description

Technical Field

[0001] This utility model relates to a production device, specifically a polymer denitrification catalyst production device, belonging to the field of polymer denitrification catalyst production technology. Background Technology

[0002] The production of polymeric denitrification catalysts refers to the process of using polymeric materials as carriers or structural templates to load active denitrification components onto a polymeric matrix through physicochemical methods, thereby preparing catalysts with catalytic selectivity, high temperature resistance, and corrosion resistance for use in industrial processes to control nitrogen oxide emissions.

[0003] Chinese Patent Publication CN217940018U discloses a polymer denitration catalyst preparation device. The stirring rod and agitator form a stirring mechanism. This mechanism can perform longitudinal and transverse stirring within the chamber under the drive of a motor, allowing the raw materials to be quickly fused, thereby improving the fusion efficiency.

[0004] While the aforementioned patented technology can enhance the mixing effect through multi-axis stirring in practical use, the device can only add materials to specific locations, resulting in severely uneven material distribution. This increases the difficulty of subsequent mixing, requiring a longer time to achieve uniform mixing, which can negatively impact the preparation efficiency of the polymer denitration catalyst. Therefore, a polymer denitration catalyst production device is proposed here. Utility Model Content

[0005] This invention proposes a polymer denitrification catalyst production device to solve the problem in the prior art that the catalyst can only be added to a specific location, resulting in a severely uneven distribution of the incoming material.

[0006] This utility model is achieved through the following technical solution: a polymer denitrification catalyst production device, including a mixing cylinder, a cylinder cover slidably connected to the inner wall of the mixing cylinder, and a rotating mechanism provided above the mixing cylinder; The rotating mechanism includes a servo motor, the bottom surface of which is fixedly connected to the upper surface of the cylinder cover. A first bevel gear is fixedly connected to the output end of the servo motor. A second bevel gear is meshed with the outer surface of the first bevel gear. A stirring shaft is fixedly connected to the inner wall of the second bevel gear. The top end of the stirring shaft is rotatably connected to the inner wall of the cylinder cover. A feed pipe is fixedly connected to the inner wall of the stirring shaft. A sealed rotary joint is fixedly connected to the top end of the feed pipe. A feeding assembly is provided above the mixing cylinder.

[0007] The feeding assembly includes a feeding cylinder, and a fixed cylinder is provided below the feeding cylinder. Two guide pipes are fixedly connected to the outer surface of the fixed cylinder. The top end of one guide pipe is fixedly connected to the bottom surface of the feeding cylinder, and the bottom end of the other guide pipe is fixedly connected to the top end of the sealing rotary joint. A feeding shaft is rotatably connected to the inner wall of the fixed cylinder. Pulleys are fixedly connected to the outer surface of the left end of the feeding shaft and the power output end of the servo motor. A synchronous belt is rotatably connected to the outer surfaces of the two pulleys.

[0008] The bottom surface of the mixing cylinder is fixedly connected to three support legs, and the bottom surface of each support leg is fixedly connected to a base.

[0009] The inner wall of the cylinder cover is threaded with several bolts, and the bottom end of each bolt is threaded to the inner wall of the mixing cylinder.

[0010] A sealed bearing is fixedly connected to the outer surface of the stirring shaft, and the outer ring of the sealed bearing is fixedly connected to the inner wall of the cylinder cover.

[0011] The outer surface of the feed cylinder and the outer surface of the fixed cylinder are jointly connected to two support plates, and the bottom surface of each support plate is fixedly connected to the upper surface of the cylinder cover.

[0012] This invention provides a polymer denitration catalyst production device, which has the following beneficial effects: This polymer denitrification catalyst production device uses a servo motor to drive the meshing of the first and second bevel gears, which in turn rotates the stirring shaft. Simultaneously, the material feeding shaft operates synchronously via pulleys and a synchronous belt. The feed cylinder, fixed cylinder, and guide pipe form a closed-loop material conveying system. Combined with a sealed rotary joint, this ensures that material is dynamically and multi-pointly added to the mixing cylinder during the stirring shaft's rotation. This dynamic feeding mode allows the material to be evenly distributed inside the cylinder as the stirring shaft rotates, avoiding localized accumulation and significantly reducing the initial unevenness of material distribution. The feed pipe embedded in the stirring shaft enables integrated operation of feeding and stirring simultaneously. Upon entering, the material is immediately dispersed by the rotating stirring shaft, effectively shortening the time required for uniform mixing. The material feeding shaft ensures uniform feeding, preventing inconsistent feeding speeds and amounts, further reducing mixing time. The overall structure achieves precise synchronization of feeding and stirring through mechanical linkage, reducing dead zones and preventing over- or under-mixing caused by uneven material distribution.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-5 This utility model provides a polymer denitrification catalyst production device, including a mixing cylinder 1, a cylinder cover 2 slidably connected to the inner wall of the mixing cylinder 1, and a rotating mechanism 3 provided above the mixing cylinder 1; The rotating mechanism 3 includes a servo motor 301. The bottom surface of the servo motor 301 is fixedly connected to the upper surface of the cylinder cover 2. Three support legs 5 are fixedly connected to the bottom surface of the mixing cylinder 1. A base 6 is fixedly connected to the bottom surface of each support leg 5. The three support legs 5 are fixed to the bottom surface of the mixing cylinder 1 to form a triangular support structure, which can effectively distribute the weight of the mixing cylinder 1 and the internal materials, and prevent the device from tipping over due to instability of the center of gravity during the mixing operation. The base 6 increases the contact area between the support legs 5 and the ground, further enhancing the placement stability of the device.

[0017] Please refer to this carefully. Figure 1The output end of the servo motor 301 is fixedly connected to the first bevel gear 303, and the outer surface of the first bevel gear 303 is meshed with the second bevel gear 304. The inner wall of the cylinder cover 2 is threaded with several bolts 8, and the bottom end of each bolt 8 is threaded to the inner wall of the mixing cylinder 1. The bolts 8 achieve a tight fixation between the cylinder cover 2 and the mixing cylinder 1 through the threaded connection, so as to prevent the cylinder cover 2 from loosening and shifting due to equipment vibration during the mixing operation, and ensure the airtightness of the mixing cylinder 1. At the same time, the detachable design of the bolts 8 facilitates the subsequent inspection, cleaning and replacement of components such as the stirring shaft 302 and the feed pipe 305 inside the mixing cylinder 1.

[0018] Please refer to this carefully. Figure 3 The inner wall of the second bevel gear 304 is fixedly connected to a stirring shaft 302. The top end of the stirring shaft 302 is rotatably connected to the inner wall of the cylinder cover 2. The inner wall of the stirring shaft 302 is fixedly connected to a feed pipe 305. The top end of the feed pipe 305 is fixedly connected to a sealing rotary joint 306. The outer surface of the stirring shaft 302 is fixedly connected to a sealing bearing 9. The outer ring of the sealing bearing 9 is fixedly connected to the inner wall of the cylinder cover 2. The sealing bearing 9 provides stable support for the rotation of the stirring shaft 302, reduces the shaking of the stirring shaft 302 when rotating at high speed, ensures the stability of the stirring process, and also prevents material leakage.

[0019] Please refer to this carefully. Figure 3 and Figure 5 A feeding assembly 4 is provided above the mixing cylinder 1. The feeding assembly 4 includes a feeding cylinder 401 and a fixed cylinder 402 is provided below the feeding cylinder 401. Two guide pipes 406 are fixedly connected to the outer surface of the fixed cylinder 402. The top end of one guide pipe 406 is fixedly connected to the bottom surface of the feeding cylinder 401, and the bottom end of the other guide pipe 406 is fixedly connected to the top end of the sealing rotary joint 306. A feeding shaft 403 is rotatably connected to the inner wall of the fixed cylinder 402. Pulleys 404 are fixedly connected to the outer surface of the left end of the feeding shaft 403 and the power output end of the servo motor 301. The outer surfaces of the two pulleys 404 are rotatably connected to a synchronous belt 40. 5. Through the transmission cooperation of pulley 404 and synchronous belt 405, the feeding shaft 403 and servo motor 301 form a power linkage, eliminating the need for additional drive equipment. The two guide pipes 406 respectively realize the stable connection between the feeding cylinder 401 and the fixed cylinder 402, and between the fixed cylinder 402 and the sealed rotary joint 306, forming a closed material conveying channel. At the same time, in conjunction with the sealed rotary joint 306, it ensures that the material can be smoothly conveyed into the rotating stirring shaft 302, providing a guarantee for subsequent all-round dispersion feeding. The setting of feeding shaft 403 can realize uniform feeding, avoiding the situation of inconsistent feeding speed and quantity, and further reducing the mixing time required.

[0020] Please refer to this carefully. Figure 1The outer surface of the feed cylinder 401 and the outer surface of the fixed cylinder 402 are jointly connected to two support plates 7. The bottom surface of each support plate 7 is fixedly connected to the upper surface of the cylinder cover 2. The support plates 7 make the feed cylinder 401 and the fixed cylinder 402 form an integrated structure with the cylinder cover 2, which improves the overall structural strength of the device, ensures that the collaborative operation is not affected by structural shaking, and guarantees the stability and reliability of the device operation.

[0021] When using this utility model: First, the operator connects the servo motor 301 to the external power supply and controller. Then, when the raw materials need to be mixed for production, the operator turns on the servo motor 301 and gradually pours the materials to be added into the feed cylinder 401. After the material enters the feed cylinder 401, it flows into the fixed cylinder 402 through one of the guide pipes 406 under the action of gravity. At this time, the servo motor 301 runs and drives the pulley 404 fixedly connected to its power output end to rotate. Through the transmission of the synchronous belt 405, the pulley 404 on the feeding shaft 403 rotates synchronously, thereby causing the feeding shaft 403 to rotate inside the fixed cylinder 402. The rotation of the feeding shaft 403 can evenly transport the material in the fixed cylinder 402 to the sealed rotary joint 306 through another guide pipe 406. The material enters the feed pipe 305 through the sealed rotary joint 306 and then enters the mixing cylinder 1. Meanwhile, the operation of the servo motor 301 also drives the first bevel gear 303, which is fixedly connected to its power output end, to rotate. The first bevel gear 303 meshes with the second bevel gear 304, causing the second bevel gear 304 to drive the stirring shaft 302 to rotate inside the cylinder cover 2. During the rotation of the stirring shaft 302, the stirring blades fixed on its outer surface stir the material entering the mixing cylinder 1. Since the material can drive the feed pipe 305 to rotate during the rotation of the stirring shaft 302, it can be dynamically and multi-pointly added into the mixing cylinder 1. This dynamic feeding mode allows the material to be evenly distributed inside the mixing cylinder 1 as the stirring shaft 302 rotates, avoiding local accumulation and greatly reducing the unevenness of the initial distribution of the material. At the same time, the feed pipe 305 embedded in the stirring shaft 302 is designed to realize the integrated operation of feeding and stirring at the same time. After the material enters, it is immediately dispersed by the rotating stirring shaft 302, effectively shortening the time for the material to reach uniform mixing. The feeding shaft 403 enables uniform feeding, avoiding inconsistent feeding speeds and amounts, and further reducing the mixing time. The overall structure achieves precise synchronization of feeding and stirring through mechanical linkage, which not only reduces stirring dead zones but also avoids over-stirring or under-stirring caused by uneven material distribution.
