Description

Technical Field

[0001] This application relates to the field of activated carbon preparation technology, and in particular to a multi-stage raw material mixing device for the preparation of desulfurization and denitrification activated carbon. Background Technology

[0002] In the preparation of desulfurization and denitrification activated carbon, the uniformity of raw material mixing has a significant impact on the subsequent activation stage and the quality of the final product. Existing mixing devices often suffer from low mixing efficiency and poor mixing uniformity, making it difficult to meet the high requirements of desulfurization and denitrification activated carbon preparation. Therefore, there is an urgent need for a multi-stage raw material mixing device for the preparation of desulfurization and denitrification activated carbon. Utility Model Content

[0003] This application provides a multi-stage raw material mixing device for the preparation of desulfurization and denitrification activated carbon. The device is equipped with a premixing chamber, a shearing chamber, and a vibration chamber. The premixing chamber is used to transport materials and perform dry premixing of coal powder and catalyst. The shearing chamber uses high-speed rotation to shear and disperse agglomerated materials and low-speed rotation to scrape the walls, preventing materials from sticking to the inner wall of the chamber and ensuring thorough mixing of materials within the chamber, thereby improving product quality. The vibration plates in the three-stage mixing chamber vibrate to disperse the mixed and agglomerated materials within the chamber and prevent them from sticking together. The three mixing chambers perform multi-stage mixing of the raw materials for the preparation of desulfurization and denitrification activated carbon, ensuring thorough mixing of coal powder, catalyst, and binder, improving the uniformity of raw material mixing and the stability of the subsequent activation stage, while also increasing mixing efficiency.

A hopper is provided at the top of the premixing chamber. A rotating shaft is provided inside the premixing chamber. One end of the rotating shaft passes through the side wall of the premixing chamber and is connected to a motor. Spiral blades are provided on the side wall of the rotating shaft. A vertical rod is welded to the bottom of one side of the premixing chamber and is welded to a base. The bottom of the other side of the premixing chamber is connected to and fixed to the top of the shearing chamber. A rotating shaft is provided at the top of the shearing chamber and is located inside the shearing chamber. A motor is connected to the top of the rotating shaft. Two shearing blades are provided on the side wall of the rotating shaft. A connecting column is movably provided on each of the upper and lower inner walls of the shearing chamber. A motor is connected to the connecting column at the bottom of the inner wall of the shearing chamber. Two frame-type stirring rods are connected to the side walls of the two connecting columns. A scraper is provided at the bottom of each of the two frame-type stirring rods. An inclined discharge port is provided at the bottom of the shearing chamber. A sealing plate is provided on the side wall of the shearing chamber at the position corresponding to the discharge port. A support rod is welded to each of the two opposite outer walls of the shearing chamber and is welded to the base.

[0005] A vibration chamber is located below the shearing chamber, and a vibration plate is located at the bottom of the vibration chamber. An ultrasonic generator is connected to the vibration plate by a wire. The ultrasonic generator is mounted on the base. Several transducers are installed inside the vibration plate, and the transducers are connected in series by wires. One end of the wire is connected to the ultrasonic generator.

[0009] Furthermore, a material inlet is provided at the top of the vibration chamber, located below the sealing plate.

[0010] Furthermore, a door is hinged to the side wall of the vibration cavity.

[0011] Furthermore, the vibration chamber is mounted on a support, which is placed on a base.

[0012] As can be seen from the above technical solution, this application provides a multi-stage raw material mixing device for the preparation of desulfurization and denitrification activated carbon, including: a premixing chamber, a shearing chamber, and a vibration chamber. A hopper is provided at the top of the premixing chamber, through which the required coal powder and catalyst are successively fed into the premixing chamber. A rotating shaft is installed inside the premixing chamber, with one end of the shaft penetrating through the side wall of the premixing chamber and connected to a motor. Spiral blades are provided on the side wall of the rotating shaft. The motor is connected to a power source. Starting the motor drives the rotating shaft to rotate, which in turn drives the spiral blades on the rotating shaft to convey and initially mix the materials in the premixing chamber. A vertical rod is welded to the bottom of one side of the premixing chamber. Welded to the base, the upright supports the premixing chamber. The bottom of the other side of the premixing chamber is connected to and fixed to the top of the shearing chamber. The material, after preliminary mixing in the premixing chamber, is conveyed to the shearing chamber by spiral blades. The binder is added into the shearing chamber through the feed pipe for mixing. A second rotating shaft is installed at the top of the shearing chamber, located inside the shearing chamber. A second motor is connected to the top of the second rotating shaft. Two shearing blades are installed on the side wall of the second rotating shaft. The second motor is connected to a power source. When the second motor is started, it drives the second rotating shaft to rotate at high speed, which in turn drives the two disc shearing blades on the second rotating shaft to rotate at high speed. The shearing blades drive the outer teeth to rotate at high speed to shear and disperse the material in the shearing chamber. For the adhered material, a connecting column is movably installed on each of the upper and lower inner walls of the shearing chamber. A motor is connected to the connecting column at the bottom of the shearing chamber's inner wall. Two frame-type stirring rods are connected to the side walls of the two connecting columns. Each frame-type stirring rod has a scraper at its bottom. The motor is connected to a power source. When the motor is started, it drives the bottom connecting column to rotate at a low speed. The connecting column then drives the frame-type stirring rods to rotate at a low speed, thereby scraping the material adhered to the inner wall of the shearing chamber. The scrapers at the bottom of the frame-type stirring rods scrape and stir the material at the bottom of the shearing chamber. The rotating shaft in the premixing chamber drives the spiral blades to transport the material, mixing the coal powder and catalytic cracking agent. The agent is used for dry premixing. The shearing disc in the shearing chamber rotates at high speed to shear and disperse the bonded materials, and the frame-type stirring rod rotates at low speed to scrape the wall, so as to avoid the materials sticking to the inner wall of the chamber and losing materials. This ensures that the materials in the chamber are fully mixed, thereby improving product quality. An inclined discharge port is set at the bottom of the shearing chamber. A sealing plate is set on the side wall of the shearing chamber at the position of the discharge port. After the materials in the shearing chamber are mixed, the sealing plate is manually opened and the materials in the shearing chamber are discharged from the discharge port one after another. A support rod is welded to each of the two opposite outer walls of the shearing chamber. The two support rods are welded to the base and support the shearing chamber.A vibration chamber is located below the shearing chamber, and a vibrating plate is installed at the bottom of the vibration chamber. An ultrasonic generator is connected to the vibrating plate and mounted on a base. The vibrating plate contains several transducers connected in series by wires, one end of which is connected to the ultrasonic generator. When the ultrasonic generator is turned on, the ultrasonic vibration waves generated are transmitted to each transducer via the wires. The transducers vibrate, causing the vibrating plate to vibrate, thereby dispersing the mixed and agglomerated materials in the vibration chamber, preventing them from sticking together and affecting subsequent processes. The three mixing chambers perform multi-stage mixing of the raw materials for desulfurization and denitrification activated carbon preparation, ensuring thorough mixing of coal powder, catalyst, and binder, improving the uniformity of raw material mixing and the stability of the subsequent activation stage, while also increasing mixing efficiency.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] 1. The device is equipped with three mixing chambers: a premixing chamber, a shearing chamber, and a vibration chamber. The three mixing chambers perform multi-stage mixing of the raw materials for the preparation of desulfurization and denitrification activated carbon, so that the coal powder, catalyst, and binder are fully mixed, improving the uniformity of raw material mixing and the stability of the subsequent activation stage, while also improving the mixing efficiency.

[0015] 2. The device is equipped with a premixing chamber and a shearing chamber. The rotating shaft drives the spiral blades to transport the material and perform dry premixing of coal powder and catalyst. In the shearing chamber, the high-speed rotating shearing disc shears and disperses the agglomerated material, and the low-speed rotating frame stirring rod scrapes the wall to prevent the material from sticking to the inner wall of the chamber and losing material. This ensures that the material in the chamber is fully mixed, thereby improving product quality.

[0016] 3. The device is equipped with a vibration chamber, which uses ultrasonic waves generated by an ultrasonic generator to drive the vibration plate to vibrate. The mixed and agglomerated materials in the chamber are dispersed to prevent them from sticking together and affecting subsequent processes. Attached Figure Description

[0023] As can be seen from the above technical solutions, see [link / reference]. Figures 1-2 .

[0024] Example 1:

[0025] A multi-stage raw material mixing device for the preparation of desulfurization and denitrification activated carbon includes: a premixing chamber 1, a shearing chamber 2, and a vibration chamber 3. A hopper is installed at the top of the premixing chamber 1, through which the required coal powder and catalyst are successively fed into the premixing chamber 1. A rotating shaft 4 is installed inside the premixing chamber 1, with one end of the shaft passing through the side wall of the premixing chamber 1 and connected to a motor 5. Spiral blades are installed on the side wall of the rotating shaft 4. The motor 5 is connected to a power source. When the motor 5 is started, it drives the rotating shaft 4 to rotate, causing the spiral blades on the rotating shaft 4 to convey and initially mix the materials in the premixing chamber 1. A vertical rod is welded to the bottom of one side of the premixing chamber 1 and is welded to a base 17. The vertical rod supports the premixing chamber. 1. Premixing chamber 1 serves a supporting function. The bottom of the other side of premixing chamber 1 is connected and fixed to the top of shearing chamber 2. The material initially mixed in premixing chamber 1 is conveyed to shearing chamber 2 by spiral blades. The binder is added into shearing chamber 2 through a feed pipe to mix with the material. A rotating shaft 6 is installed at the top of shearing chamber 2, located inside shearing chamber 2. A motor 8 is connected to the top of rotating shaft 6. Two shearing blades 7 are installed on the side wall of rotating shaft 6. Motor 8 is connected to a power source. When motor 8 is started, it drives rotating shaft 6 to rotate at high speed, which in turn drives the two disc shearing blades 7 on rotating shaft 6 to rotate at high speed. The shearing blades 7 drive the outer teeth to rotate at high speed to shear and disperse the bonded material in shearing chamber 2. A connecting column 9 is movably installed on each of the upper and lower inner walls of the shearing chamber 2. A motor 11 is connected to the connecting column 9 at the bottom of the inner wall of the shearing chamber 2. Two frame-type stirring rods 10 are connected to the side walls of the two connecting columns 9. Each frame-type stirring rod 10 has a scraper 12 at its bottom. The motor 11 is connected to a power source. When the motor 11 is started, it drives the connecting column 9 at the bottom to rotate at a low speed. The connecting column 9 drives the frame-type stirring rods 10 to rotate at a low speed, thereby scraping the material adhering to the inner wall of the shearing chamber 2. The scraper 12 at the bottom of the frame-type stirring rods 10 scrapes the material at the bottom of the shearing chamber 2. The rotating shaft 4 in the premixing chamber 1 drives the spiral blades to transport the material. Coal powder and catalyst are dry premixed. The shearing disc in the shearing chamber 2 rotates at high speed to shear and disperse the bonded materials, and the frame stirring rod 10 rotates at low speed to scrape the wall, so as to avoid the materials sticking to the inner wall of the chamber and losing materials, so that the materials in the chamber are fully mixed, thereby improving the product quality. The bottom of the shearing chamber 2 is provided with an inclined discharge port. The side wall of the shearing chamber 2 is provided with a sealing plate 13 corresponding to the position of the discharge port. After the materials in the shearing chamber 2 are mixed, the sealing plate 13 is manually opened, and the materials in the shearing chamber 2 are discharged from the discharge port one after another. A support rod is welded to each of the two opposite outer walls of the shearing chamber 2. The two support rods are welded to the base 17, and the support rods provide support for the shearing chamber 2.

[0026] A vibration chamber 3 is located below the shearing chamber 2. A vibration plate 14 is located at the bottom of the vibration chamber 3. An ultrasonic generator 16 is connected to the vibration plate 14 and mounted on a base 17. Several transducers 15 are installed inside the vibration plate 14 and connected in series by wires. One end of each wire is connected to the ultrasonic generator 16. When the ultrasonic generator 16 is turned on, the ultrasonic vibration waves generated by the ultrasonic generator 16 are transmitted to each transducer 15 via the wires. The transducers 15 vibrate, causing the vibration plate 14 to vibrate, thereby dispersing the mixed and agglomerated materials in the vibration chamber 3 and preventing them from sticking together. This will affect subsequent processes. The three mixing chambers perform multi-stage mixing of the raw materials for the preparation of desulfurization and denitrification activated carbon, ensuring thorough mixing of coal powder, catalyst, and binder, improving the uniformity of raw material mixing and the stability of the subsequent activation stage, while also increasing mixing efficiency.

[0027] In a preferred embodiment, a feed pipe is provided at the top of the shearing chamber 2, through which a binder is fed into the shearing chamber 2, so that it is mixed with the material after the coal powder and catalyst are mixed.

[0028] In a preferred embodiment, each shearing blade 7 is uniformly provided with a number of teeth on its periphery. The teeth facilitate the shearing and dispersing of the bonded material in the shearing cavity 2, so as to make it fully mixed.

[0029] In a preferred embodiment, rubber slots and rubber plates are provided on both sides respectively. When materials are mixed in the shearing chamber 2, the sealing plate 13 is pushed in from the rubber slot on one side and pressed against the rubber plate on the other side to fix the sealing plate 13.

[0030] In a preferred embodiment, a material outlet is provided at the top of the vibration chamber 3, which is located below the sealing plate 13, so that the material after mixing in the shearing chamber 2 can be discharged and enter the vibration chamber 3 through the material outlet.

[0031] In a preferred embodiment, a door is hinged to the side wall of the vibration chamber 3. After the material in the vibration chamber 3 has completed vibration and dispersion, the ultrasonic generator 16 is turned off, the door on the side wall of the vibration chamber 3 is opened, and the mixed material is manually discharged for subsequent preparation of desulfurization and denitrification activated carbon.

[0032] In a preferred embodiment, the vibration chamber 3 is mounted on a support base, which is placed on the base 17. The support base supports the vibration chamber 3 and prevents the vibration of the vibration chamber 3 from affecting other equipment on the base 17.
