Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery parts processing, in particular to an eddy current powder separator capable of preventing inner wall adhesion. Background Art
[0002] The eddy current powder classifier is an efficient and practical powder screening equipment, which is mainly used to classify powders of different particle sizes to achieve certain fineness requirements. Its principle is based on the eddy current principle. The powder particles are divided into different sizes by a high-speed rotating turbine, and then screened through a screen. The working principle of the eddy current powder classifier is based on the eddy current principle, that is, the powder particles are broken up and classified by a high-speed rotating turbine to complete the screening process. However, the existing eddy current powder classifiers are all separated by centrifugal force. The material of different particle sizes is separated. This method will cause a large number of fine particles to adhere to the inside of the classifier and cannot be cleaned in time, causing the entire sorting system to be blocked. Utility Model Content
[0003] The purpose of the utility model is to provide an eddy current powder classifier with anti-inner wall adhesion in view of the shortcomings of the prior art, so as to solve the problem proposed in the above background technology that the existing eddy current powder classifiers all use centrifugal force to sort materials of different particle sizes. This method will cause a large number of fine particles to adhere to the inside of the classifier and cannot be cleaned in time, thereby causing the entire sorting system to be blocked.
[0004] To achieve the above object, the utility model provides the following technical solutions: an eddy current powder classifier for preventing inner wall adhesion, comprising a powder classifying structure, an inner wall cleaning structure is arranged directly below the powder classifying structure, and pipeline cleaning structures are arranged on both sides of the powder classifying structure;
[0005] The powder selection structure includes a powder selection bin, a material inlet is provided above the powder selection bin, a material outlet is provided just below the powder selection bin, a grading area is provided just above the material outlet, air inlets are provided on both sides of the grading area, and air outlets are provided at both ends of the material inlet;
[0006] A first motor is arranged on one side just above the powder selection bin, and the first motor drives the driving wheel to rotate, and the driving wheel is transmitted to the driven wheel through a belt.
[0007] Preferably, the driven wheel is fixedly connected to the dispersion disk via a rotating shaft, and the rotating shaft is arranged at the center of the feed inlet.
[0008] By adopting the above technical scheme, when the dry coarse and fine powders enter the dispersion disk in the powder selection bin from the feed port, the first motor is used to drive the driving wheel to rotate, and the driving wheel is transmitted to the driven wheel through the belt. During the rotation of the driven wheel, the dispersion disk is rotated through the rotating shaft. Under the action of centrifugal force, the material is thrown onto the baffle ring on the dispersion disk. After being blocked by the baffle ring, the material is evenly scattered downward in the grading area. At the same time, the airflow enters the powder selection bin tangentially from the air inlet. Because of the negative pressure generated by the rotation of the grading area, a rotating and rising space column is formed. Due to the interaction of the centripetal attraction of the airflow, the centrifugal force and gravity, the fine particles are classified and enter the air outlet, while the coarse particles enter the outlet below under the action of gravity, thereby achieving the effect of powder selection and grading.
[0009] Preferably, the inner wall cleaning structure includes a screw rod, which is fixed directly below the dispersion disk and is slidably provided with a slider.
[0010] Preferably, spring rods are symmetrically fixed on the sliding block, and an arc-shaped cleaning block is fixedly arranged on the spring rods.
[0011] By adopting the above technical solution, when the first motor drives the dispersion disk to rotate, the dispersion disk drives the screw rod below it to rotate during the rotation process, and the slider slides up and down during the rotation of the screw rod. During the up and down sliding of the slider, the arc-shaped cleaning block is brought into close contact with the inner wall of the powder selection bin through the spring rod, thereby achieving the effect of cleaning the inner wall of the powder selection machine.
[0012] Preferably, the pipeline cleaning structure includes a first rotating shaft, which is rotatably connected to a second rotating shaft via a universal coupling, and fan blades are fixedly provided on the first rotating shaft and the second rotating shaft.
[0013] Preferably, the first rotating shaft and the second rotating shaft are arranged in the center of the air outlet, and the fan blades are in contact with the inner wall of the air outlet.
[0014] By adopting the above technical solution, when airflow and fine particles pass through the air outlet, the fan blades and the first rotating shaft are driven to rotate. During the rotation of the first rotating shaft, the second rotating shaft is rotated through the universal coupling. During the rotation of the fan blades, the fine particles adhering to the inner wall of the air outlet will be processed in time, thereby achieving the effect of cleaning the pipeline.
[0015] Compared with the prior art, the utility model has the following beneficial effects: the eddy current powder separator with anti-inner wall adhesion is
[0016] (1) This case sets up an inner wall cleaning structure to solve the problem that the existing eddy current powder separators use centrifugal force to separate materials of different particle sizes. This method will cause a large number of fine particles to adhere to the inside of the separator and cannot be cleaned in time, causing the entire separation system to be blocked. When the first motor drives the dispersion disk to rotate, the dispersion disk drives the screw below it to rotate during the rotation of the dispersion disk. The screw rotates and the slider slides up and down. During the sliding of the slider, the spring rod makes the arc cleaning block closely contact the inner wall of the powder selection bin, thereby achieving the effect of cleaning the inner wall of the powder separator. In addition, the arc cleaning block is set up so that the arc cleaning block can fit the curved and curved parts of the inner wall of the powder separator, so that the cleaning is more comprehensive.
[0017] (2) By setting up: a pipeline cleaning structure, the problem that some particles of the existing eddy current powder separator adhere to the inner wall of the air outlet when the fine particles pass through the air outlet is solved. When the air flow and fine particles pass through the air outlet, the fan blades and the first rotating shaft are driven to rotate. During the rotation of the first rotating shaft, the second rotating shaft is rotated through the universal coupling. During the rotation of the fan blades, the fine particles adhering to the inner wall of the air outlet are blown away, thereby achieving the effect of pipeline cleaning.
