Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalyst production technology, specifically to a processing device for NO2 removal honeycomb catalysts. Background Technology
[0002] Nitrogen oxides are a major component of air pollution, with NO2 emission control receiving particular attention. As environmental standards continue to tighten, the demand for NO2 removal honeycomb catalysts in industry and transportation is increasing. These catalysts are widely used in purification technologies due to their advantages such as large specific surface area and high catalytic efficiency.
[0003] The processing of NO2 removal honeycomb catalysts involves key steps such as raw material mixing and screening. Traditional processing equipment often has several shortcomings. On the one hand, in the raw material mixing stage, the stirring effect is poor, and the layout design of the stirring rods and plates is unreasonable, making it difficult to achieve sufficient and uniform mixing of the raw materials. This results in uneven distribution of raw materials during catalyst preparation, affecting the activity and performance of the catalyst. On the other hand, in the raw material screening stage, there is a lack of efficient and automated screening mechanisms. The screening process is inefficient, and the screening effect is difficult to guarantee. It is easy to have impurities remaining or insufficient screening of qualified raw materials. This not only increases the difficulty of subsequent processing but may also affect the quality of the final catalyst product. In addition, the lack of effective linkage and collaborative working mechanisms between the various components of traditional equipment makes the entire processing flow cumbersome and inefficient, unable to meet the needs of large-scale, efficient production of NO2 removal honeycomb catalysts. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a NO2 removal honeycomb catalyst processing device, which solves the problem that some of the added raw materials may agglomerate into larger particles, thus affecting the efficiency of subsequent stirring and heating of these raw materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a NO2 removal honeycomb catalyst processing device, comprising a heating and stirring assembly, with a screening assembly at the top of the heating and stirring assembly; the heating and stirring assembly includes a heating cylinder, with a cylinder cover fixedly installed at one end of the outer wall of the heating cylinder, and two stirring rods rotatably installed on the inner wall of the heating cylinder, with a set of stirring plates fixedly installed on the outer walls of each of the two stirring rods, the two sets of stirring plates being staggered; the screening assembly includes a feeding frame, with a screening frame disposed within the feeding frame, two sliding rods fixedly installed on both sides of the screening frame, and four sliding rods slidingly penetrating the feeding frame at their ends away from the screening frame, each of the four sliding rods being fitted with a spring, and a pressing plate fixedly installed on one side wall of the screening frame, with a cam disposed on one side of the pressing plate.
[0006] Preferably, one end of each of the two stirring rods slides through the cylinder cover and is fixedly mounted with a gear, the two gears meshing with each other, an L-shaped plate is fixedly mounted on the outer wall of the cylinder cover, and a motor is fixedly mounted on the end of the L-shaped plate away from the cylinder cover.
[0007] Preferably, the output shaft of the motor passes through the L-shaped plate and is sequentially fitted with a drive wheel and one of the two gears. The outer wall of the heating cylinder is provided with a transparent observation window. The top of the heating cylinder is fixedly connected to a liquid inlet pipe, and the bottom of the heating cylinder is fixedly connected to a liquid drain valve.
[0008] Preferably, the two ends of the outer walls of the four springs are fixedly connected to the inner wall of the feeding frame and the outer wall of the screening frame, respectively. The bottom end of the screening frame is provided with a screening hole, and a rotating rod is rotatably installed on the outer wall of the feeding frame.
[0009] Preferably, one end of the rotating rod is fixedly connected to the cam, and the other end of the rotating rod is fixedly mounted with a driven wheel. The outer walls of the driven wheel and the driving wheel are fitted with belts, and the diameter of the driving wheel is larger than the diameter of the driven wheel.
[0010] Preferably, the bottom end of the feeding frame is provided with two inclined sides, the feeding frame and the heating cylinder are fixedly connected through the feeding bin, two support plates are fixedly installed between the feeding frame and the heating cylinder, and two bottom plates are fixedly installed on the outer wall of the heating cylinder.
[0011] Compared with existing technologies, it has the following advantages:
[0012] 1. In this NO2 removal honeycomb catalyst processing device, when raw material screening is required, the raw material is first poured into the screening frame, then the motor is turned on. The motor's output shaft drives the drive wheel to rotate, which in turn drives the driven wheel to rotate via a belt. The driven wheel then drives the rotating rod to rotate, and the cam on the rotating rod rotates accordingly. During rotation, the cam intermittently squeezes the extrusion plate, causing the screening frame to reciprocate along the slide bar under the action of the spring. This screens the raw material placed in the screening frame, removing larger particles and nodules. The qualified raw material passes through the screening holes at the bottom of the screening frame and falls into the heating cylinder through the feeding bin. By setting up the screening components and utilizing the cooperation of components such as the cam, extrusion plate, screening frame, slide bar, and spring, the added raw material can be effectively screened, removing larger particles and nodules. This ensures that the raw material particles entering the heating and stirring components are of uniform size, providing a good foundation for subsequent stirring and heating, and improving the raw material processing efficiency.
[0013] 2. In this NO2 removal honeycomb catalyst processing device, the screened raw materials enter the heating cylinder. The output shaft of the motor is also fixedly connected to one of the gears, driving two meshing gears to rotate, which in turn causes the two stirring rods to rotate in opposite directions. The stirring plates on the stirring rods are arranged alternately to stir the raw materials in the heating cylinder, making the stirring more thorough and enabling the raw materials to be mixed more evenly in the heating cylinder, which is beneficial to improving the processing quality of the catalyst.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides two technical solutions:
[0022] Figures 1-5 The first embodiment is shown: a NO2 removal honeycomb catalyst processing apparatus, including a heating and stirring assembly 1, with a screening assembly 2 provided at the top of the heating and stirring assembly 1;
[0023] The heating and stirring assembly 1 includes a heating cylinder 11. The inner wall of the heating cylinder 11 can be provided with a heating device such as a resistance wire to heat the inside of the cylinder. A cylinder cover 12 is fixedly installed at one end of the outer wall of the heating cylinder 11. Two stirring rods 13 are rotatably installed on the inner wall of the heating cylinder 11. A set of stirring plates 14 is fixedly installed on the outer wall of each of the two stirring rods 13. The two sets of stirring plates 14 are arranged alternately.
[0024] The screening component 2 includes a feeding frame 21, within which a screening frame 23 is installed. Two slide rods 24 are fixedly installed on both sides of the screening frame 23. The ends of the four slide rods 24 that are away from the screening frame 23 slide through the feeding frame 21. Springs 25 are fitted on each of the four slide rods 24. The slide rods 24 can limit the screening frame 23, so that the screening frame 23 can only move in the direction of the slide rods 24. At the same time, the springs 25 can reset the screening frame 23, ensuring that the screening frame 23 keeps shaking. A pressing plate 26 is fixedly installed on one side wall of the screening frame 23. A cam 27 is provided on one side of the pressing plate 26. When the cam 27 rotates, it will press the pressing plate 26, thereby driving the screening frame 23 to reciprocate.
[0025] One end of each of the two stirring rods 13 slides through the cylinder cover 12 and is fixedly mounted with a gear 15. The two gears 15 are meshed with each other. When one stirring rod 13 rotates, the other stirring rod 13 can be driven to rotate in the opposite direction through the gear 15. An L-shaped plate 18 is fixedly mounted on the outer wall of the cylinder cover 12. A motor 19 is fixedly mounted on the end of the L-shaped plate 18 away from the cylinder cover 12.
[0026] The output shaft of the motor 19 passes through the L-shaped plate 18 and is sequentially fixedly fitted with the drive wheel 16 and one of the two gears 15. The outer wall of the heating cylinder 11 is provided with a transparent observation window 111. The top end of the heating cylinder 11 is fixedly connected to the liquid inlet pipe 112, and the bottom end of the heating cylinder 11 is fixedly connected to the liquid drain valve 113.
[0027] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the outer ends of the four springs 25 are fixedly connected to the inner wall of the feeding frame 21 and the outer wall of the screening frame 23, respectively. The bottom end of the screening frame 23 is provided with a screening hole. The outer wall of the feeding frame 21 is rotatably mounted with a rotating rod 28.
[0028] One end of the rotating rod 28 is fixedly connected to the cam 27, and the other end of the rotating rod 28 is fixedly installed with a driven wheel 29. The outer walls of the driven wheel 29 and the driving wheel 16 are fitted with belts 17. The diameter of the driving wheel 16 is larger than the diameter of the driven wheel 29. By increasing the rotation speed of the driven wheel 29 and the rotating rod 28, the rotation speed of the cam 27 is increased, which can increase the shaking speed of the screening frame 23 and speed up the efficiency of raw material screening.
[0029] The bottom of the feeding frame 21 is provided with two inclined sides 22. The feeding frame 21 and the heating cylinder 11 are fixedly connected through the feeding bin 210. The material screened by the screening frame 23 will fall to the bottom of the feeding frame 21 and then slide down to the feeding bin 210 through the inclined sides 22. The material can then be conveyed into the heating cylinder 11 through the feeding bin 210. Two support plates 211 are fixedly installed between the feeding frame 21 and the heating cylinder 11, which can make the feeding frame 21 stably installed on the surface of the heating cylinder 11. Two base plates 3 are fixedly installed on the outer wall of the heating cylinder 11 to improve the stability of the heating cylinder 11.
[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0031] During operation, the required liquid is first added to the heating cylinder 11 through the liquid inlet pipe 112. When the raw materials need to be screened, the raw materials are first poured into the screening frame 23. At this time, the raw materials that meet the requirements will fall into the heating cylinder 11. In order to improve the filtration rate of the raw materials, the motor 19 is turned on. The output shaft of the motor 19 drives the drive wheel 16 to rotate. The drive wheel 16 drives the driven wheel 29 to rotate through the belt 17. The driven wheel 29 then drives the rotating rod 28 to rotate. The cam 27 on the rotating rod 28 rotates accordingly. During its rotation, cam 27 intermittently presses against extrusion plate 26, causing screening frame 23 to reciprocate along slide bar 24 under the action of spring 25. This screens the raw materials placed in screening frame 23, removing larger particles and nodules. The qualified raw materials then pass through the screening holes at the bottom of screening frame 23 and fall into heating cylinder 11 via discharge bin 210. By setting up screening assembly 2 and utilizing the cooperation of components such as cam 27, extrusion plate 26, screening frame 23, slide bar 24, and spring 25, the added raw materials can be effectively screened, removing larger particles and nodules, ensuring that the raw material particles entering heating and stirring assembly 1 are of uniform size. This provides a good foundation for subsequent stirring and heating, improving the processing efficiency of raw materials. The output shaft of the motor 19 is also fixedly connected to one of the gears 15, driving two meshing gears 15 to rotate, which in turn causes the two stirring rods 13 to rotate in opposite directions. The stirring plates 14 on the stirring rods 13 are arranged alternately to stir the raw materials in the heating cylinder 11, making the stirring more thorough and enabling the raw materials to be mixed more evenly in the heating cylinder 11, which is beneficial to improving the processing quality of the catalyst. The stirring and heating status of the raw materials and liquid can be observed through the transparent observation window 111. When the requirements are met, the liquid can be discharged through the drain valve 113.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
