Description

Technical Field

[0001] This application relates to the field of cement denitrification, and in particular to a dust collection structure for cement denitrification. Background Technology

[0002] In the cement production industry, denitrification is a crucial environmental protection process, playing a vital role in reducing nitrogen oxide emissions and protecting the environment. With increasingly stringent environmental requirements, cement denitrification technology is constantly evolving. Effective denitrification not only helps companies meet environmental regulations but also enhances their social image and sustainable development capabilities. Ash collection is a key step in the cement denitrification process, playing a vital role in ensuring the normal operation of denitrification equipment and its effectiveness. A well-designed ash collection structure can prevent dust from affecting the operation of denitrification reactors and other equipment, improving equipment lifespan and operating efficiency.

[0003] In related technologies, dust falls downwards from the reactor through a dust collection channel and is collected, then transported to other areas. However, a large amount of dust easily remains on the side walls of the dust collection channel, gradually hardening and causing incomplete dust collection, or even clogging the channel. This necessitates frequent manual cleaning of the inner walls of the dust collection channel, increasing labor costs and intensity. Utility Model Content

[0004] In order to ensure thorough dust collection and reduce labor costs and intensity, this application provides a dust collection structure for cement denitrification.

[0005] The ash collection structure for cement denitrification provided in this application adopts the following technical solution:

[0006] A dust collection structure for cement denitrification includes a denitrification reactor and a dust collection channel fixed to and connected to the lower end of the denitrification reactor. The lower end of the dust collection channel is provided with a screw conveyor. The screw conveyor includes a conveying pipe connected to the dust collection channel. An auger is rotatably connected inside the conveying pipe. A drive motor for driving the auger to rotate is connected to the conveying pipe. An inclined conveying chute is fixed to and connected to the lower part of one end of the conveying pipe. A vibrating motor is fixedly connected to the outer wall of the dust collection channel.

[0007] By adopting the above technical solution, the denitrification reactor is used for cement denitrification. The dust collection channel collects dust during the denitrification process. The screw conveyor rotates under the drive of the drive motor, which can transport the dust falling in the dust collection channel to the inclined conveying chute for easy dust discharge. The vibrating motor can make the dust collection channel vibrate, reducing the accumulation and caking of dust in the dust collection channel, making the dust collection thorough, and reducing labor costs and labor intensity.

[0008] Preferably, the ash collection channel is an inverted conical cylinder.

[0009] By adopting the above technical solution, the dust collection channel of the inverted cone cylinder can make the collected dust slide more smoothly to the bottom under the action of gravity, which is conducive to the dust being concentrated in the screw conveyor for transportation.

[0010] Preferably, the inner wall of the ash collection channel is provided with a smooth layer.

[0011] By adopting the above technical solution, the dust collection channel can easily collect dust, and the smooth layer can reduce the occurrence of dust adhering to the inner wall of the dust collection channel, which helps the dust to fall smoothly to the screw conveyor. By driving the auger to rotate through the drive motor, the dust can be transported to the inclined conveying chute for discharge.

[0012] Preferably, the inner wall of the conveying chute is fixedly connected with an anti-stick coating.

[0013] By adopting the above technical solutions, the occurrence of dust adhering to the inner wall of the conveying chute can be reduced, ensuring smooth material conveying, reducing dust residue, and improving conveying efficiency.

[0014] Preferably, a sealing ring is fixedly connected at the connection between the denitrification reactor and the ash collection channel, and a sealing ring is also fixedly connected at the connection between the ash collection channel and the conveying pipe.

[0015] By adopting the above technical solution, sealing rings are installed at the connection between the denitrification reactor and the ash collection channel, and at the connection between the ash collection channel and the conveying pipeline. This can limit the occurrence of leakage at the connection, ensure the sealing of the ash collection structure, and improve the stability and reliability of the cement denitrification and ash collection process.

[0016] Preferably, the vibration motor includes a motor body and a mounting bracket, the mounting bracket being slidably connected to the outer wall of the ash collection channel, and a locking component connected to the mounting bracket to lock the mounting bracket and the ash collection channel.

[0017] By adopting the above technical solution, the mounting bracket of the vibratory motor is slidably connected to the outer wall of the ash collection channel and is equipped with a locking component, which makes it easy to adjust and lock the position of the vibratory motor on the outer wall of the ash collection channel, thereby enabling strong vibration at different positions of the ash collection channel to ensure that the accumulated ash in the ash collection channel can be shaken off more effectively.

[0018] Preferably, a sliding rod is fixedly connected to the outer wall of the ash collection channel, and a dovetail groove is provided on the mounting frame. The shape of the sliding rod is adapted to the shape of the dovetail groove, and the sliding rod and the dovetail groove are slidably connected.

[0019] By adopting the above technical solution, the mounting bracket of the vibratory motor can slide stably along the slide bar on the outer wall of the ash collection channel, which facilitates the adjustment of the position of the vibratory motor. Furthermore, the matching structure between the dovetail groove and the slide bar can prevent the mounting bracket from detaching during the sliding process, thereby improving the stability of the vibratory motor installation.

[0020] Preferably, two vibration motors are installed on the outer wall of the ash collection channel, with the two vibration motors located at the upper and lower ends of the outer wall of the ash collection channel, respectively.

[0021] By adopting the above technical solution, vibration motors are installed at the upper and lower ends of the outer wall of the dust collection channel, which can vibrate different positions of the dust collection channel, enhance the falling effect of dust in the dust collection channel, and make dust collection more efficient.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Reduces dust accumulation and caking in the dust collection channel, ensuring thorough dust collection and reducing labor costs and labor intensity;

[0024] 2. Ensure the airtightness of the ash collection structure to improve the stability and reliability of the cement denitrification and ash collection process;

[0025] 3. It facilitates the adjustment and locking of the position of the vibrating motor on the outer wall of the ash collection channel, thereby enabling powerful vibration at different positions of the ash collection channel. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0030] This application discloses an ash collection structure for cement denitrification. (Refer to...) Figure 1 and Figure 2The ash collection structure includes two denitrification reactors 1 and an ash collection channel 2 connected to each denitrification reactor 1. The denitrification reactor 1 is located at the upper end of the ash collection channel 2 and is fixed and communicated with the upper end of the ash collection channel 2. A screw conveyor 3 is provided at the lower end of the ash collection channel 2. The screw conveyor 3 includes a transversely arranged conveying pipe 31 and an auger 32 rotatably connected inside the conveying pipe 31. A drive motor 33 is fixedly connected to the outer wall of one end of the conveying pipe 31, and the output shaft of the drive motor 33 is coaxially fixedly connected to the auger 32.

[0031] The lower end of each ash collection channel 2 is fixed and connected to the conveying pipe 31 in the same screw conveyor 3. The end of the conveying pipe 31 away from the drive motor 33 is fixedly connected to a conveying chute 34, which is located below the conveying pipe 31.

[0032] Dust generated during the operation of the denitrification reactor 1 falls into the conveying pipe 31 along the ash collection channel 2. The drive motor 33 is started, and the output shaft of the drive motor 33 drives the screw conveyor 32 to rotate, thereby conveying the dust in the conveying pipe 31 to one end near the conveying chute 34, and then it is discharged along the conveying chute 34.

[0033] Reference Figure 1 and Figure 2 Each dust collection channel 2 is equipped with a vibration motor 4 on its outer wall. When the vibration motor 4 is started, it can assist the dust to fall smoothly, thus improving the dust collection efficiency and stability.

[0034] The dust collection channel 2 is an inverted conical cylinder, and the inner wall of the dust collection channel 2 is provided with a smooth layer. The smooth layer can be formed by grinding the inner wall of the dust collection channel 2 to reduce the friction between the dust and the inner wall of the dust collection channel 2, so that the dust can slide off more smoothly.

[0035] The dust collection channel 2 is generally welded from metal plates. Its upper end is fixedly connected to the denitrification reactor 1 by a flange. A sealing ring 5 is fixedly connected at the connection. The sealing ring 5 can be a rubber O-ring, which can limit dust leakage.

[0036] The dust collection channel 2 and the conveying pipe 31 are fixedly connected by a flange, and a sealing ring 5 is also fixedly connected at the connection to limit dust leakage.

[0037] The conveying chute 34 is inclined, and its inner wall is fixedly coated with an anti-stick coating, such as a Teflon coating, to reduce dust adhesion to the inner wall of the conveying chute 34. The conveying chute 34 is generally made of metal sheet. One end of the conveying chute 34 is fixed and connected to the lower end of the conveying pipe 31 by welding or flange connection, allowing gravity to cause the dust to slide down within the conveying chute 34.

[0038] Each dust collection channel 2 has two vibrating motors 4 slidably connected to its outer wall. The two vibrating motors 4 are located at the upper and lower ends of the outer wall of the dust collection channel 2. The vibrating motors 4 at the upper and lower ends can generate vibrations in different directions and frequencies, which can more effectively promote the falling of dust.

[0039] Each vibration motor 4 includes a motor body 41 and a mounting bracket 42. The motor body 41 is fastened to the mounting bracket 42 by screws, and the mounting bracket 42 is slidably connected to the outer wall of the ash collection channel 2.

[0040] Reference Figure 1 and Figure 2 Two sliding rods 6 are fixedly connected to the outer wall of the ash collection channel 2, with one sliding rod 6 corresponding to one vibrating motor 4. A dovetail groove 421 is provided on the mounting frame 42, and the shape of the sliding rod 6 matches that of the dovetail groove 421, with the sliding rod 6 slidably connected to the dovetail groove 421. A locking component 7 is connected to the mounting frame 42 to lock the mounting frame 42 and the sliding rod 6. This allows the mounting frame 42 to slide on the sliding rod 6, facilitating the adjustment of the position of the vibrating motor 4.

[0041] The locking assembly 7 includes screws that fasten the mounting bracket 42 to the slide bar 6. By tightening the screws, the mounting bracket 42 is locked to the ash collection channel 2.

[0042] The implementation principle of the dust collection structure for cement denitrification in this embodiment is as follows: During the cement denitrification process, the generated dust falls down the smooth layer of the dust collection channel 2 to the conveying pipe 31 under the action of gravity and the vibration motor 4. The drive motor 33 drives the auger 32 to rotate, conveying the dust to the inclined conveying chute 34. The anti-stick coating can limit the adhesion of dust, allowing the dust to slide down smoothly and detach from this dust collection structure.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
