Abstract
Description
Technical Field
[0001] This utility model relates to the field of phosphor production technology, specifically a dust removal device for phosphor production. Background Technology
[0002] Phosphors are inorganic or organic light-emitting materials that release energy through electron transitions and produce visible light or light of a specific wavelength after being excited by external energy (such as ultraviolet light, visible light, electron beams, electric fields, etc.). Their light-emitting principle involves mechanisms such as photoluminescence, cathodoluminescence, and electroluminescence. They have the characteristics of high brightness, long afterglow, and adjustable color, and are widely used in fluorescent lamps, LED lighting, displays, anti-counterfeiting labels, biomarkers, radiation detection, and other fields. According to their composition, they can be divided into rare earth doped, sulfide, silicate, and nitride systems. Their performance is affected by factors such as crystal structure, type and concentration of activator, and matrix material. It is necessary to take into account luminous efficiency, stability, lifespan, and environmental adaptability.
[0003] In existing phosphor production processes, conventional cleaning procedures typically employ mechanical contact brush cleaning. This method involves direct physical contact between the brush and phosphor particles, which can easily generate high-intensity shear stress during operation. This causes some phosphor particles to break or disintegrate due to mechanical friction, resulting in particle size distribution deviating from the design range and affecting the uniformity of the product's optical performance. At the same time, the broken ultrafine particles can easily generate secondary dust, causing dust concentrations in the production environment to exceed standards and reducing raw material utilization and increasing production costs due to particle escape.
[0004] Based on this, the present invention designs a dust removal device for phosphor production to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a dust removal device for phosphor production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A dust removal device for phosphor production includes a workbench. An electrical control box is fixedly installed at the right end of the workbench. A dust blowing mechanism and a material guiding mechanism are arranged above the workbench. The dust blowing mechanism includes a support column, a material guiding bin, a dust bin, an installation groove, and a filter screen. A support column is fixedly installed at the upper end of the workbench. A material guiding bin is fixedly installed at the upper end of the support column. A dust bin is inserted into the left end of the material guiding bin. An installation groove is formed on the inner wall of the material guiding bin. A filter screen is installed inside the installation groove. The material guiding mechanism includes an installation plate, a material guiding cloth, and an ultrasonic cleaner. An ultrasonic cleaner is fixedly installed at the right end of the support column. An installation plate is fixedly installed at the upper end of the ultrasonic cleaner. A material guiding cloth is installed at the upper end of the installation plate.
[0008] Optionally, the dust blowing mechanism further includes an air guide chamber and a brushless fan. The air guide chamber is fixedly installed at the right end of the material guide chamber, and a brushless fan is installed at the right end of the air guide chamber. Two sets of brushless fans are installed on the air guide chamber.
[0009] Optionally, a guide hopper is fixedly installed at the upper end of the guide hopper, and a second mounting base is fixedly installed on the inner wall of the guide hopper.
[0010] Optionally, a spring body is fixedly mounted on the upper end of the second mounting base, and a first mounting base is fixedly mounted on the upper end of the spring body.
[0011] Optionally, a first guide plate and a second guide plate are fixedly installed on the upper end of the first mounting base, and the two sets of the first guide plates and the second guide plates are installed from top to bottom inside the guide hopper.
[0012] Optionally, a vibration motor is provided at the lower end of the first guide plate and the second guide plate, and the two sets of vibration motors are distributed below the first guide plate and the second guide plate.
[0013] Optionally, the filter screen is located between the dust bin and the air guide bin, and the material guide cloth is located below the material guide bin.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model includes a dust blowing mechanism. The dust blowing mechanism solves the defects of traditional mechanical contact cleaning through the synergistic effect of a high-frequency dust-vibrating structure and a wind-powered dust-blowing structure. Specifically, the high-frequency vibration of the first and second guide plates driven by the vibrating motor, combined with the elastic assistance of the spring body, can peel off dust without damaging the particles, ensuring the stability of the phosphor particle size distribution. At the same time, the wind system composed of the brushless fan and the air guide chamber blows the shaken-off dust into the dust chamber through directional airflow, and is isolated by the filter screen, which not only suppresses the problem of secondary dust, but also improves the utilization rate of raw materials. In addition, this structure replaces brush friction with physical separation, which significantly reduces the dust concentration in the production environment and meets the requirements of environmental protection and occupational health.
[0016] 2. In this utility model, a material guiding mechanism is provided. Through the optimized design of the material guiding cloth and the ultrasonic cleaner, the material guiding mechanism achieves fine processing of phosphor particles. The material guiding cloth is made of flexible fabric, which not only avoids particle collision and breakage that may be caused by rigid material guiding plates, but also guides the particles to enter the ultrasonic cleaner smoothly by tilting, ensuring the integrity of the particles. Based on the pre-treatment of the dust blowing mechanism, the ultrasonic cleaner only needs to treat the residual trace dust, which greatly reduces the pollution of the cleaning fluid by cavitation, extends the service life of the cleaning fluid, and shortens the single cleaning cycle, thus comprehensively improving the dust removal efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-9 In this embodiment of the present invention, a dust removal device for phosphor production includes a workbench 1. An electrical control box 4 is fixedly installed on the right end of the workbench 1. A dust blowing mechanism 2 and a material guiding mechanism 3 are arranged above the workbench 1. The dust blowing mechanism 2 includes a support column 201, a material guiding bin 202, a dust bin 203, an installation groove 204, and a filter screen 205. The support column 201 is fixedly installed on the upper end of the workbench 1, and the material guiding bin 202 is fixedly installed on the upper end of the support column 201. The dust bin 203 is inserted into the left end of the material guiding bin 202. An installation groove 204 is provided on the inner wall of the material guiding bin 202, and a filter screen 205 is installed inside the installation groove 204. The dust blowing mechanism 2 also includes an air guide chamber 213 and a brushless fan 214. The air guide chamber 213 is fixedly installed on the right end of the material guiding bin 202, and a brushless fan 214 is installed on the right end of the air guide chamber 213. 14. Two sets of brushless fans 214 are installed on the air guide chamber 213. A guide hopper 206 is fixedly installed at the upper end of the guide chamber 202. A second mounting base 212 is fixedly installed on the inner wall of the guide chamber 202. A spring body 211 is fixedly installed at the upper end of the second mounting base 212. A first mounting base 210 is fixedly installed at the upper end of the spring body 211. A first guide plate 207 and a second guide plate 208 are fixedly installed at the upper end of the first mounting base 210. The two sets of first guide plates 207 and second guide plates 208 are installed from top to bottom inside the guide chamber 202. A vibration motor 209 is provided at the lower end of the first guide plate 207 and the second guide plate 208. The two sets of vibration motors 209 are distributed below the first guide plate 207 and the second guide plate 208. The filter screen 205 is located between the dust chamber 203 and the air guide chamber 213.
[0031] The dust blowing mechanism 2 combines a high-frequency vibration dust removal structure and a wind-powered dust blowing structure. The high-frequency vibration dust removal structure consists of a first guide plate 207, a second guide plate 208, a vibration motor 209, a first mounting base 210, a spring body 211, and a second mounting base 212. The wind-powered dust blowing structure consists of an air guide chamber 213 and a brushless fan 214. Before activation, the vibration motor 209 and the brushless fan 214 need to be powered on and connected to the control terminal. During activation, the fluorescent powder to be dusted is injected through the guide hopper 206. The fluorescent powder falls onto the first guide plate 207. At the same time, the vibration motor 209 drives the first guide plate 207 and the second guide plate 208 to vibrate at high frequency. With the elastic assistance of the spring body 211, the fluorescent powder moves along the first guide plate 207 and the second guide plate 208. As the material plate 208 slides, it is effectively vibrated. This high-frequency vibration does not break the phosphor particles; instead, it shakes out the dust inside the phosphor. The phosphor then falls to the left side of the air guide chamber 213. At this time, the brushless fan 214 blows a gentle breeze from right to left. The breeze blows the dust through the filter screen 205 into the dust chamber 203, while the phosphor continues to fall downwards and eventually falls into the material guide mechanism 3 for further cleaning. The high-frequency dust-vibrating structure can quickly vibrate out the dust adhering to the surface of the phosphor, preventing dust from adhering to the phosphor and improving the subsequent dust removal intensity. In addition, when combined with the wind-blown dust structure, the vibrated dust can be blown away and collected, which not only removes the dust but also reduces the working pressure of the subsequent ultrasonic cleaner 303.
[0032] The material guiding mechanism 3 includes a mounting plate 301, a material guiding cloth 302, and an ultrasonic cleaner 303. The ultrasonic cleaner 303 is fixedly installed on the right end of the support column 201, and the mounting plate 301 is fixedly installed on the upper end of the ultrasonic cleaner 303. The material guiding cloth 302 is installed on the upper end of the mounting plate 301 and is located below the material guiding bin 202.
[0033] The material guiding mechanism 3 and the dust blowing mechanism 2 complement each other. With the help of the ultrasonic cleaner 303, the fluorescent particles are deeply cleaned. The difference is that after the dust treatment of the fluorescent particles by the high-frequency dust vibration structure and wind dust blowing structure in the dust blowing mechanism 2, the cleaning pressure of the ultrasonic cleaner 303 is reduced. It can quickly clean a large number of fluorescent particles, effectively reducing the frequency of changing the cleaning fluid in the ultrasonic cleaner 303. To a certain extent, it improves the overall dust removal efficiency of the equipment. Before use, the ultrasonic cleaner 303 needs to be connected to power and water and connected to the control terminal. When started, the material guiding cloth 302 receives the fluorescent particles exported from the material guiding bin 202 and guides the fluorescent particles into the ultrasonic cleaner 303 for cleaning. The material guiding cloth 302 is made of cloth and will not affect the fluorescent particles. It avoids the situation where the fluorescent particles in the phosphor may break into dust again due to gravity impact, effectively protecting the phosphor.
[0034] The working principle of this utility model is as follows: During the working process, the phosphor to be processed enters the guide chamber 202 through the guide hopper 206 and first falls onto the first guide plate 207. After the vibration motor 209 is started, it drives the first guide plate 207 and the second guide plate 208 to generate high-frequency vibration. At the same time, the spring body 211 amplifies the vibration amplitude through elastic deformation, so that the phosphor particles peel off the dust attached to their surface due to continuous vibration as they slide down the guide plate. Subsequently, the phosphor enters the left side area of the air guide chamber 213, and two sets of brushless fans 214 blow out air from right to left. The controlled airflow blows the shaken-off dust through the filter 205 into the dust chamber 203 for centralized collection. The cleaned fluorescent powder continues to fall to the guiding mechanism 3. The guiding cloth 302, made of flexible material, receives the fluorescent powder, buffers its impact, prevents secondary breakage, and guides the particles evenly into the ultrasonic cleaner 303. The ultrasonic cleaner 303 uses the cavitation effect to deeply clean the surface of the particles. Since the dust blowing mechanism 2 has removed most of the dust, the ultrasonic cleaning fluid can remain clean for a long time, reducing the frequency of replacement and further improving the overall efficiency.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
