Description

Technical Field

[0001] The utility model relates to the field of powder classifiers, in particular to a suction type lime powder classifier. Background Art

[0002] The suction powder classifier is a kind of equipment widely used in the powder industry. Its working principle is to use airflow to introduce the powder particles to be separated into the machine, and through a series of screening and separation processes, the particles of different sizes and qualities are classified and separated. In the working state, the high-speed motor drives the vertical transmission shaft to rotate through the transmission device, and the material enters the powder selection chamber through the feed port set at the upper part of the powder selection chamber, and then falls on the spreading plate through the upper and lower cones set in the medium and coarse powder collection cone and the powder pipe. The spreading plate rotates with the vertical transmission shaft, and the material is evenly spread around under the action of inertial centrifugal force. The dispersed material enters the powder selection chamber through the air inlet of the external fan under the action of high-speed airflow, and the coarse and heavy particles in the material are thrown to the inner wall of the powder selection chamber under the action of inertial centrifugal force. After the collision, the particles lose kinetic energy and slide down along the wall, falling into the coarse powder collection cone. The remaining particles are rolled up by the rotating rising airflow. When passing through the action area of ​​the large wind blade, under the impact of the large wind blade, another part of the coarse powder particles are thrown to the inner wall of the powder selection chamber. After the collision, they lose kinetic energy and slide down along the wall, falling into the coarse powder collection cone. After passing through the large wind blade, the medium coarse powder and fine powder continue to rise through the vertical guide blades under the action of the rising airflow and enter the secondary powder selection area. Under the action of the strong and stable plane vortex formed by the rotating cage rotor, the dust-laden airflow causes the medium coarse powder to be thrown to the vertical guide blades under the action of centrifugal force and lose kinetic energy, fall into the medium coarse powder collection cone, and be discharged through the medium coarse powder pipe. The fine powder that meets the requirements passes through the cage rotor and enters its interior, enters the high-efficiency and low-resistance cyclone separator with the circulating air, and then slides into the fine powder collection cone to become the finished product. When using a suction type powder classifier to separate lime particles, smaller particles of lime will enter the cyclone separator and be separated from the airflow by the centrifugal force of the rotating airflow. However, some fine particles of lime are light in weight and cannot be effectively separated from the airflow by the centrifugal force. As a result, they will still float out of the cyclone separator with the airflow, and ultimately the fine particles of lime cannot be effectively separated and collected. Therefore, a suction type lime powder classifier is needed to solve the above problem. Utility Model Content

There are four No. 1 rods 6 and they are symmetrically arranged. There are eight base plates 7 and they are fixedly installed at the upper and lower ends of the four No. 1 rods 6, respectively. There are eight No. 1 springs 8 and they are symmetrically sleeved on the four No. 1 rods 6 in pairs. The lower annular plate 9 is movably installed on the four No. 1 rods 6, and the lower annular plate 9 is located between the No. 1 springs 8 symmetrically arranged in the upper and lower parts.

The upper circular plate 14 is movably mounted on the four second rods 11, and the upper circular plate 14 is located between the second springs 12 symmetrically arranged in the upper and lower parts. The powder blocking structure 5 is located above the pipeline 16. The base plate 7 on the powder blocking structure 5 is fixedly mounted on the inner wall of the separator body 3. The lower circular plate 9 on the powder blocking structure 5 is an annular structure, and the inner diameter of the lower circular plate 9 is smaller than that of the upper circular plate 14. The outer diameter of the cyclone plate 14 is greater than the outer diameter of the upper circular plate 14. The lower circular plate 9 on the powder blocking structure 5 is symmetrically provided with four No. 1 through holes 10. The lower circular plate 9 is movably sleeved on the No. 1 rod 6 through the No. 1 through holes 10. The upper circular plate 14 is symmetrically provided with four No. 2 through holes 15.

When in use, the fine particles of lime entering the cyclone separator 2 through the pipeline 16 with the air flow will rotate in the separator body 3 with the air flow, and the centrifugal force generated by the rotation will cause the fine particles of lime to collide with the inner wall of the separator body 3, so that some of the fine particles of lime will be decelerated and fall to the bottom of the cyclone separator 2 under the influence of gravity. At the same time, some lighter fine particles of lime will rise with the air flow. At this time, the lower annular plate 9 and the upper circular plate 14 on the powder blocking structure 5 can block the fine particles of lime that rise with the air flow. The rising fine particles of lime are blocked, thus forcing them to fall under gravity, and the air flow enters the air outlet pipe 4 through the gap between the lower annular plate 9 and the upper circular plate 14, and when the air flow passes between the lower annular plate 9 and the upper circular plate 14, the lower annular plate 9 and the upper circular plate 14 will be blown, and at the same time, under the elastic force of the No. 1 spring 8 and the No. 2 spring 12, the lower annular plate 9 and the upper circular plate 14 will vibrate, and then the lime attached to the lower annular plate 9 and the upper circular plate 14 can be shaken off, thereby avoiding a large amount of lime attached to the lower annular plate 9 and the upper circular plate 14.
