Abstract
Description
Technical Field
[0001] The utility model relates to a disintegrating classifier. Background Art
[0002] Traditional disintegrating methods and classification equipment have obvious limitations. Common mechanical impact disintegrating devices, such as hammer crushers, achieve disintegration by hitting materials with high-speed rotating hammers. However, this method is prone to generating large impact forces, resulting in excessive fragmentation of particles. Moreover, for materials with tight agglomeration or severe caking, the disintegration effect is not good.
[0003] In addition, some disintegrating equipment based on the vibration principle can, to a certain extent, separate agglomerated particles. However, for caking materials with high viscosity or high hardness, it is often difficult to achieve an ideal disintegration effect, and the energy loss during the vibration process is large.
[0004] In terms of classification technology, the technology based on air classification can achieve relatively fine classification. However, it requires additional independent classification equipment, so two sets of equipment for disintegration and classification need to work independently, resulting in high energy consumption and increased equipment investment.
[0005] In actual production, in fields such as chemical industry, building materials, and metallurgy, it is often necessary to perform fine disintegration and classification on materials. However, due to the difficulty of simultaneously achieving efficient disintegration and precise classification in the prior art, not only the production efficiency and product quality are affected, but also the processing difficulty and cost of subsequent processes are increased.

[0012] As a preferred technical solution, a plurality of feeding through holes are arranged on the partition board and are evenly distributed.
[0013] As a preferred technical solution, a diversion conical cover sleeved outside the sleeve is fixedly installed in the feeding cavity, and the small end of the diversion conical cover is close to the partition board.
[0014] As a preferred technical solution, the dispersion blades extend spirally.
[0015] As a preferred technical solution, the air inlet includes an upper air inlet located at the upper part of the feed chamber and a lower air inlet located at the lower part of the feed chamber, and air volume regulating valves are respectively installed on the upper air inlet and the lower air inlet.
[0016] Due to the adoption of the above technical solution, a horizontal dispersion classifier includes a housing. The housing is provided with a feed chamber and a dispersion classification chamber.

The fine material discharge pipe extends into the diversion ring, and classification blades are fixedly installed between the outer peripheral surface of the diversion ring and the front surface of the dispersion classification disk.

The dispersed material enters the action range of the classification blades of the dispersion classification disk under the dual action of negative pressure and the centrifugal force of the dispersion classification disk. The dispersion classification disk is provided with classification blades and a diversion ring. Since the kinetic energies generated by the thick and fine particle materials are different when they are affected by the centrifugal force generated by the dispersion classification disk, the thick and fine particles are separated. The fine particles with small kinetic energy are taken into the diversion ring by negative pressure and separated, and the thick particles fall into the thick particle discharge port and are discharged. The dispersion classification disk simultaneously realizes that the dispersion and classification structures are more compact, and only this one part can meet the requirements of dispersion and classification. The coarse powder discharge port can timely discharge the coarse particles, avoiding the accumulation of coarse particles that are not easily pulverized in the dispersion classification chamber and ensuring the dispersion and classification efficiency.

[0020] Figure 4 is Figure 3 a side view of. Specific embodiments
[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a horizontal dispersion and classification machine includes a housing 1. The housing 1 is provided with a feed chamber 2 and a dispersion and classification chamber 3. A partition 4 is provided between the feed chamber 2 and the dispersion and classification chamber 3. A feed through hole 5 is provided on the partition 4. A dispersion and classification disk 6 is rotatably installed in the dispersion and classification chamber 3. A dispersion hammer 7 and dispersion vanes 8 located inside the dispersion hammer 7 are fixedly installed on the back surface of the dispersion and classification disk 6. An annular lining 9 cooperating with the dispersion hammer 7 is provided on the inner wall of the dispersion and classification chamber 3. A coarse powder discharge port 10 is opened at the lower part of the dispersion and classification chamber 3. A valve is installed on the coarse powder discharge port 10. An inlet 11 is provided at the upper part of the housing 1. The upper parts of the feed chamber 2 and the dispersion and classification chamber 3 are interconnected. The inlet 11 faces the feed chamber 2. An air inlet is opened in the feed chamber 2. A fine material outlet 13 is opened in the dispersion and classification chamber 3. A fine material discharge pipe 14 is installed on the fine material outlet 13. A diversion ring 15 is fixedly installed in the middle of the front surface of the dispersion and classification disk 3. The fine material discharge pipe 14 extends into the diversion ring 15. A classification vane 16 is fixedly installed between the outer peripheral surface of the diversion ring 15 and the front surface of the dispersion and classification disk 6. The material to be classified enters from the inlet 11. The material falls into the feed chamber 2 and enters the dispersion and classification chamber under the action of the internal negative pressure and the wind force of the air inlet. The dispersion and classification disk rotates at a high speed and the material is fully dispersed by the blowing of the dispersion vanes and the impact of the dispersion hammer 7. The dispersed material enters the action range of the classification vanes of the dispersion and classification disk under the dual action of the negative pressure and the centrifugal force of the dispersion and classification disk. The front surface of the dispersion and classification disk is provided with classification vanes and a diversion ring. Since the kinetic energies generated by the thick and fine particles of the material are different when the centrifugal force generated by the dispersion and classification disk acts on them, the thick and fine particles are separated. The fine particles with small kinetic energy are taken into the diversion ring by the negative pressure and separated, and the thick particles fall into the thick particle discharge port and are discharged. The dispersion and classification disk realizes both dispersion and classification at the same time, and the structure is more compact. The coarse powder discharge port 10 can timely discharge the coarse particles, avoiding the accumulation of coarse particles that are not easily pulverized in the dispersion and classification chamber, and ensuring the dispersion and classification efficiency.
[0022] As Figure 1 、 Figure 2As shown, through holes 17 are formed in the partition plate 4. The drive shaft 18 of the dispersion classification disk 6 penetrates from the feed chamber 2 through the through holes 17 into the dispersion classification chamber 3. A sleeve 19 is sleeved outside the drive shaft 18, and the sleeve 19 is fixedly installed between the partition plate 4 and the inner wall of the housing 1. A drive shaft sleeve 24 is also sleeved outside the drive shaft 18 and located between the sleeve 19 and the drive shaft 18. The drive shaft sleeve 24 is fixedly installed on the housing 1. A plurality of sealing annular grooves are provided on the front end surface of the drive shaft sleeve 24. A classification disk sleeve 25 is provided in the middle of the back surface of the dispersion classification disk 6. The classification disk sleeve 25 and the dispersion classification disk are of an integral structure. A sealing annular protrusion matching with the sealing annular groove is provided on the rear end surface of the classification disk sleeve 25. A partition cavity 20 is formed by the rear surface of the partition plate 4, the inner surface of the sleeve 19, the outer peripheral surface of the classification disk sleeve 25, and the outer peripheral surface of the drive shaft sleeve 24.
[0023] As Figure 2 shown, air inlet holes 22 are provided on the outer peripheral surface of the sleeve 19. The air inlet holes 22 are connected to a high-pressure air source, and the high-pressure air source is communicated with the partition cavity 20. The air inlet holes 22 are also communicated with the partition cavity 20. Airflow enters from the air inlet holes 22, preventing particles from entering the partition cavity 20 through the through holes 17 and ensuring the efficient operation of the equipment.
[0024] As Figure 2 shown, the feeding through hole 5 is located between the dispersion hammers 7 and the dispersion blades 8 and is directly opposite to the inner end of the dispersion hammer 7, enabling the material to be more effectively acted upon by the dispersion blades and the dispersion hammers.
[0025] Preferably, the feeding through hole 5 extends horizontally. There are multiple feeding through holes which are evenly distributed on the partition plate. A guiding conical cover 21 sleeved outside the sleeve 19 is fixedly installed in the feed chamber 2, and the small end of the guiding conical cover 21 is adjacent to the partition plate 4. The guiding conical cover 21 enables the material to pass through each feeding through hole 5 more efficiently. Moreover, the arrangement of the guiding conical cover 21 enables the airflow generated by the high-pressure air source to enter the air inlet holes 22 along the outer surface of the guiding conical cover 21, effectively preventing particles from entering the partition cavity 20 through the through holes 17.
[0026] Preferably, the dispersion blades 8 extend spirally.
[0027] As Figure 1 shown, the air inlet includes an upper air inlet 12 located in the upper part of the feed chamber 2 and a lower air inlet 23 located in the lower part of the feed chamber 2. Air volume regulating valves are respectively installed on the upper air inlet 12 and the lower air inlet 23.
