Description

Technical Field

[0001] The utility model relates to the technical field of powder separators, in particular to a new type of high-efficiency fine powder separator. Background Technique

[0002] There are many types of powder separators. Different types are suitable for different materials, and different models are also made according to the requirements of customers for the fineness of materials. Generally, common powder separators include cyclone powder separators, three-separation powder separators, centrifugal powder separators, special powder separators for coal mills, special powder separators for calcium powder, etc. Later, many high-efficiency powder separators and high-efficiency three-separation powder separators have been developed. They are new-generation products that improve deficiencies and increase production on the basis of the original ones.

[0003] For example, the air powder separator disclosed in the publication number CN213558455U. The beneficial effects of this utility model are as follows: The buffer assembly reduces the vibration of the air powder separator when it is running, makes the pressure on the frame and the foundation assembly more stable, does not affect the foundation, extends its overhaul period, reduces the maintenance frequency, and reduces the noise generated by vibration through vibration reduction, making the working environment quieter. However, this powder separator needs to use a fan to generate air flow for classification and transmission, and is relatively sensitive to external environmental conditions. When the wind speed or wind pressure is unstable, it will affect the operation effect and classification accuracy of the powder separator. In the air powder separator, it is necessary to separate dust and fine powder through the force of the air flow. However, due to the small density of dust and fine particles, there is a certain degree of suspension, which will lead to difficulties in separating air and powder and affect the classification effect. Secondly, this powder separator lacks a screening mechanism and cannot effectively control the particle size of the material, and cannot classify the material according to the required particle size, which may result in uneven particles in the output and does not meet the requirements.

[0004] Therefore, there is an urgent need for a new type of high-efficiency fine powder separator to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of high-efficiency fine powder separator, which has the advantages of high-efficiency pulverization and good particle size separation effect, and solves the problems that when the wind speed or wind pressure is unstable, it will affect the operation effect and lacks a screening mechanism, and cannot effectively control the particle size of the material and classify the material according to the required particle size of the above-mentioned powder separator.

[0006] To achieve the above object, the present utility model provides the following technical solution: a novel and efficient fine powder separator, comprising a box body, a feed pipe is connected to the top of the box body, a discharge pipe is connected to one side of the bottom of the box body, a fixed seat is fixedly connected to one side of the box body, a motor is fixedly connected to the top of the fixed seat, an output shaft of the motor penetrates into the inner cavity of the box body and is fixedly connected to a driving bevel gear, a crushing chamber is arranged in the inner cavity of the box body, a conical plate is arranged in the inner cavity of the box body, a plurality of crushing blocks are fixedly connected to the surfaces of the conical plate and the crushing chamber, a driven bevel gear is fixedly connected to the bottom of the conical plate, and the driven bevel gear meshes with the driving bevel gear;

[0007] A screening mechanism, the screening mechanism includes a connecting plate fixedly connected to one side of the box body, a motor is fixedly connected to the bottom of the connecting plate, an output shaft of the motor penetrates to the top of the connecting plate and is fixedly connected to a round block, a moving arm is rotatably connected to one side of the top of the round block, and one side of the moving arm extends into the inner cavity of the box body and is rotatably connected to a screen.

[0008] Preferably, a through hole is formed in one side of the box body, and one side of the moving arm is slidably connected to the inner wall of the through hole.

[0009] Preferably, an installation seat is sleeved on the surface of the motor, and the bottom of the installation seat is fixedly connected to the fixed seat.

[0010] Preferably, limiting rods are fixedly connected to both sides of the inner cavity of the box body, and both sides of the screen are slidably connected to the limiting rods.

[0012] Preferably, a valve is arranged on the surface of the discharge pipe. Through the arrangement of the valve, the function of adjusting the speed of material outflow is achieved.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] This utility model has the advantages of high - efficiency crushing and good particle size separation effect. During actual use, through the combined use of the conical plate, crushing blocks, and crushing chamber, the material can be effectively crushed and refined. Through precise crushing actions, materials with relatively large original particle sizes can be processed into the required fine particles, which can improve the uniformity and consistency of the product. Subsequently, through the combined use of the screening mechanism, the original particles can be separated according to different particle sizes, achieving particle size control and classification, effectively excluding oversized particles, ensuring the particle size uniformity and consistency of the product. By precisely separating and screening the particle size, the quality and quality stability of the product can be improved, solving the problems that when the wind speed or wind pressure of the existing powder separator is unstable, it will affect the operation effect and there is a lack of a screening mechanism, making it impossible to effectively control the particle size of the material and impossible to classify the material according to the required particle size.

[0026] Working principle: First, the raw materials are fed into the feed pipe 10 of the powder separator and flow onto the surface of the conical plate 6 through the feed pipe 10. The user starts the motor 3. While the output shaft of the motor 3 rotates, it drives the driving bevel gear 4 to rotate. While the driving bevel gear 4 rotates, it drives the driven bevel gear 5 to engage and transmit power. While the driven bevel gear 5 rotates, it drives the conical plate 6 to rotate. During the movement of the conical plate 6, the raw materials are subjected to pressure and impact force through the crushing blocks 7, causing the raw materials to be crushed and ground, so as to achieve the purpose of pulverization. When it is necessary to screen the pulverized materials, the user starts the motor 11. The output shaft of the motor 11 rotates to drive the round block 13 to rotate. While the round block 13 rotates, it drives the moving arm 14 to swing. While the moving arm 14 swings, it drives the screen 15 to vibrate, prompting the raw materials to move and jump on the screen 15 to increase the contact between the particles and the sieve holes, as well as the collision and separation between each other. By the combined use of the valve 18 and the discharge pipe 20, the outflow speed of the materials can be controlled to achieve safe, efficient and reliable operation.
