Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a vortex combined powder classifier. Background Art

[0002] In modern industrial production, vortex-type combined powder classifiers, as an important type of powder processing equipment, are widely used in industries such as cement, chemicals, and metallurgy. With the continuous advancement of industrial technology, the performance requirements for powder classifiers are becoming increasingly stringent. They require not only efficient powder selection but also excellent stability and convenience. Against this backdrop, continuously improving and innovating the structure and functionality of powder classifiers to meet the production needs of various industries has become a key research topic.

[0003] Existing vortex-type combined classifiers typically utilize traditional mechanical structures and technical principles. They generally include a housing, rotor, transmission, feed port, and discharge port. During operation, material enters the classifier through the feed port. The high-speed rotation of the rotor generates centrifugal force and airflow, causing the material to be sorted within the classifier. Finer particles are carried out by the airflow and discharged through the discharge port, while coarser particles fall to the bottom of the classifier under the influence of gravity and are discharged through another outlet. This traditional classifier can meet production needs to a certain extent, but it also has some shortcomings. For example, its structure is relatively complex, resulting in high manufacturing and maintenance costs; its sorting efficiency and accuracy need to be improved; and its adaptability to materials of different properties is limited.

[0004] During the use of existing vortex combination powder classifiers, the screened materials often accumulate on the top of the partition and cannot be discharged conveniently. This is because the structural design of traditional powder classifiers does not fully consider the discharge method of the materials. After the materials are sorted, some of the materials will fall on the partition and easily accumulate on the top of the partition, which not only affects the normal operation of the powder classifier, but also reduces the powder selection efficiency. Over time, the accumulated materials will cause damage to the equipment and increase maintenance costs. In addition, the accumulated materials will also affect the airflow distribution inside the powder classifier, further reducing the powder selection effect. For this reason, a vortex combination powder classifier is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a vortex combined powder classifier, which aims to improve the problem in the prior art that the sorted raw materials are easily accumulated on the top of the partition and cause the device to be blocked.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a vortex combined powder classifier, including a powder selection tank 1, the powder selection tank 1 is made of high-strength stainless steel, has good corrosion resistance and pressure resistance, and can withstand various pressures and frictions in the powder selection process, the outer wall of the powder selection tank 1 is fixedly connected with a support frame 7, the support frame 7 is made of high-quality carbon steel, the structure is stable, and can provide reliable support for the powder selection tank 1, the bottom of the powder selection tank 1 is fixedly connected with a fixed shell 8, the fixed shell 8 is made of thick cast iron material, has good heat dissipation performance and protection performance, and can protect the internal motor 9 Not affected by the external environment, the fixed shell 8 is fixedly connected to the motor 9, the output belt of the motor 9 is fixedly connected to the screening bucket 11, the screening bucket 11 is made of wear-resistant alloy steel, and the surface is specially treated to have high hardness and wear resistance, and can maintain good screening performance during long-term use. The outer wall of the screening bucket 11 is provided with a sorting component, which is used to screen the raw materials. The powder selection tank 1 is provided with an observation component, which is used to view the inside of the powder selection tank 1. The top of the powder selection tank 1 is provided with a feeding component, which is used to add the raw materials.

[0033] The separation component includes a fine powder cone partition 13, which is stamped from a stainless steel plate and has a conical shape. The outer wall of the fine powder cone partition 13 is fixedly connected to the inside of the powder selection tank 1 by welding. The surface of the fine powder cone partition 13 is smooth, which can effectively guide the flow of fine powder. The outer wall of the fine powder cone partition 13 is fixedly connected to the inside of the powder selection tank 1, and the coarse powder cone partition 14 is fixedly connected to the inside of the powder selection tank 1. The outer wall of the powder selection tank 1 is fixedly connected to the fine powder sieve outlet 5, and the fine powder sieve outlet 5 is arranged on the outside of the fine powder cone partition 13. The outer wall of the powder selection tank 1 is fixedly connected to the coarse powder sieve outlet 6, and the coarse powder sieve outlet 6 is arranged on the outside of the coarse powder cone partition 14. The fine powder cone partition 13 is rotatably connected to the inside, and the inner wall of the fixed ring 12 is fixedly connected to the outer wall of the screening bucket 11. The outer wall of the screening bucket 11 is fixedly connected to the scraper 10. The scraper 10 is made of wear-resistant rubber and has certain elasticity and flexibility. It can push the raw materials on the top of the fine powder cone partition 13 and the coarse powder cone partition 14 during rotation to prevent the raw materials from accumulating, thereby pushing the raw materials on the top of each side to prevent them from accumulating on their top and causing blockage.

[0034] Specifically, when screening, the motor 9 is started first, and the operation of the motor 9 drives the screening bucket 11 to rotate. During the rotation process, the screening bucket 11 further drives the fixed ring 12 to rotate stably inside the fine powder cone partition 13 and the coarse powder cone partition 14. At the same time, the scraper 10 connected to the fixed ring 12 also rotates synchronously on the top of the fine powder cone partition 13 and the coarse powder cone partition 14. The rotation of the scraper 10 can effectively move the screened raw materials, and continuously push the raw materials that may have accumulated on the top of the partition to the outlet. In this way, the raw materials can fall and be collected smoothly, avoiding the problem of inconvenient collection due to the accumulation of raw materials on the top of the partition, greatly improving the efficiency and convenience of the screening work. At the same time, preventing the accumulation of raw materials can also reduce the wear of the equipment. The accumulated raw materials will cause friction and damage to the internal structure of the equipment, reducing the service life of the equipment. The timely cleaning effect of the scraper 10 can effectively avoid this situation. In addition, the accumulation of raw materials will affect the flow of airflow, thereby reducing the powder selection efficiency. The existence of the scraper 10 can keep the air flow channel unobstructed, so that the air flow can be evenly distributed inside the powder classifier, thereby improving the accuracy and efficiency of powder selection.

[0035] Reference Figure 1 The observation component includes an observation window 4, which is arranged inside the powder selection tank 1.

[0036] Specifically, the observation window 4 enables the operator to observe the situation inside the powder selection tank 1 in real time during the operation of the equipment, and check the flow state of the material, the powder selection effect, and whether there are abnormal conditions such as blockage and material accumulation inside the equipment at any time. Once a problem is found, the operator can take corresponding measures in time to avoid further expansion of the problem, thereby reducing equipment downtime and maintenance costs.

[0037] Reference Figure 1 and Figure 3The feeding assembly includes a feeding pipe 2, which is made of durable stainless steel with good corrosion resistance and pressure resistance, and can maintain a stable shape and performance during long-term use. A feeding port 3 is provided inside the feeding pipe 2, and a closed groove 16 is provided inside the feeding pipe 2. A connecting plate 22 is fixedly connected to the inside of the feeding pipe 2, and a fixing plate 23 is fixedly connected to one side of the connecting plate 22. A fixing column 20 is fixedly connected to the top of the fixing plate 23. The fixing column 20 is made of high-quality carbon steel with high strength and hardness. The sliding connection inside the fixing column 20 is limited. Plate 19, the limiting plate 19 is made of wear-resistant aluminum alloy, and its surface has been specially treated to have a low friction coefficient, which allows it to slide smoothly within the fixed column 20. A spring 21 is provided inside the fixed column 20. The top of the spring 21 is fixedly connected to the bottom of the limiting plate 19, and the bottom of the spring 21 is fixedly connected to the inside of the fixed column 20. The top of the limiting plate 19 is fixedly connected to the sliding column 17, and the top of the sliding column 17 is fixedly connected to the connecting column 18. The top of the connecting column 18 is fixedly connected to the rubber plug 15. The rubber plug 15 is made of high-quality rubber material and has good elasticity and sealing. The outer wall of the rubber plug 15 is tightly slidably connected to the inside of the closed groove 16, which can effectively close the feed port 3 and prevent the backflow of raw materials. The outer wall of the rubber plug 15 is slidably connected to the inside of the closed groove 16, and the inner wall of the connecting column 18 is slidably connected to the outer wall of the connecting column 18, thereby evenly feeding the powder selection tank 1 and sealing the feed port 3 when no material is added to prevent backflow.

[0038] Specifically, when screening raw materials, the raw materials are first added to the device through the feed port 3. As the raw materials are continuously added, when the raw materials accumulate to a certain weight, downward pressure is exerted on the rubber stopper 15. Under the action of pressure, the rubber stopper 15 is pressed down, thereby driving the connecting column 18 to move downward. The movement of the connecting column 18 prompts the sliding column 17 to move synchronously. Then the sliding column 17 drives the limiting plate 19 to move. During this process, the spring 21 is compressed. At this time, the rubber stopper 15 slides out from the inside of the closed groove 16, and the raw materials are smoothly added to the powder selection tank 1. When the raw materials are insufficient in weight or have been added, the rebound of the spring 21 drives the rubber stopper 15 to slide back into the inside of the closed groove 16, thereby closing the feed port 3, effectively preventing the backflow of the raw materials, ensuring the stable progress of the powder selection process and the normal operation of the equipment, and accurately controlling the amount of material entering the powder selection machine each time. By pre-setting the weight value for triggering the feeding, it can be ensured that the feed port 3 will only be opened when the required amount of material is reached. This is crucial for the efficient and stable operation of the powder classifier, because the appropriate amount of material can keep the airflow and material dispersion state inside the powder classifier at the optimal level, and there is no need for frequent manual monitoring and operation, which reduces manual intervention. At the same time, the rubber plug 15 can provide a good sealing effect. The rubber material itself is elastic and can fit tightly to the inner wall of the feed port 3 to prevent material leakage and external impurities from entering. This is very important for maintaining a stable working environment inside the powder classifier. It can also effectively prevent material backflow. When the internal pressure of the powder classifier changes or other abnormal conditions occur, the one-way valve can ensure that the material can only enter the powder classifier in the set direction, and will not flow back into the feed pipe from the inside. This is very important for maintaining the normal order of the feeding system and protecting upstream feeding equipment.

[0039] Working principle: When the raw materials are screened, the raw materials are added through the feed port 3. When the raw materials reach a certain weight, pressure is generated on the rubber plug 15, thereby pressing it down. The rubber plug 15 then drives the connecting column 18 to move downward, and then drives the sliding column 17 to move through the connecting column 18. Then, the sliding column 17 drives the limiting plate 19 to move, compressing the spring 21, so that the rubber plug 15 slides out from the inside of the closed groove 16, and the raw materials are added to the inside of the powder selection tank 1. Then, the motor 9 is started, and the screening bucket 11 is driven to rotate by the motor 9. , and then the screening bucket 11 drives the fixed ring 12 to rotate inside the fine powder cone partition 13 and the coarse powder cone partition 14, and at the same time drives the scraper 10 to rotate on the top of the fine powder cone partition 13 and the coarse powder cone partition 14, and moves the raw materials screened out, so as to push them to the outlet for falling and collection, to prevent them from accumulating on the top of the partition and being unable to be collected conveniently. Later, when the raw material gravity is insufficient or the addition is completed, the spring 21 rebounds and drives the rubber plug 15 to slide back into the closed groove 16 to close the feed port 3 to prevent backflow.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
