Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet fluorescent powder nitrogen sintering, in particular to an ultraviolet fluorescent powder nitrogen sintering device. Background Art

[0002] Sintering is a method of preparing engineering materials by using high temperature and pressure to aggregate fine particles into larger blocks. This method is widely used in metal and ceramic manufacturing. The sintering process involves three main steps: pretreatment, heating and holding. Pretreatment usually includes mixing ingredients, grinding and ball milling to produce fine particles. The heating step involves heating the material to a high temperature to melt or soften it, and then forming a porous block under a specific pressure. The holding stage is to eliminate residual gases and make the material denser.

[0003] Nitrogen is an inert gas. It is mainly used to protect and adjust the atmosphere during the sintering process. Nitrogen can be used to replace air, reduce the oxygen content, prevent oxidation reactions and the formation of bubbles. Nitrogen can also reduce the generation of pollutants during the sintering process, thereby improving the quality of manufactured materials.

[0004] For example, the application number is CN202120938109.5, which is an oxygen extraction and nitrogen addition device for sintering optical modules, including a sintering tank, characterized in that: a base is provided at the lower surface of the sintering tank, a tank cover is hingedly provided above the sintering tank, an oxygen extraction pipeline and a nitrogen addition pipeline are fixedly connected to one side of the sintering tank, a nitrogen addition pipeline is provided above the oxygen extraction pipeline, and a control valve is embedded in the oxygen extraction pipeline and the nitrogen addition pipeline, an adjusting member is provided in front of the sintering tank, a carrier plate is provided on the adjusting member, a cooling member is provided on one side of the carrier plate, and a movable hole is provided on the carrier plate. However, the ultraviolet phosphor nitrogen sintering device directly sintered the phosphor, and the impurities doped inside the phosphor would affect the emission performance of the phosphor and the fluorescence intensity, and a filter frame is placed inside the placement slot, which is not convenient to take out after the sintering work is completed. Therefore, in view of this, the existing structural deficiencies are studied and improved, and an ultraviolet phosphor nitrogen sintering device is proposed. Utility Model Content

[0005] The utility model aims to provide a nitrogen sintering device for ultraviolet phosphor to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nitrogen sintering device for ultraviolet phosphor, comprising a sintering furnace body and a placement groove, the sintering furnace body is provided with a placement groove, and a filter frame is fixed inside the placement groove, a garbage collection frame is fixed at the bottom of the filter frame, and a movable cooling mechanism is provided at the bottom of the collection frame.

[0007] Preferably, the mobile cooling mechanism includes a base plate fixedly connected to the internal position of the sintering furnace body, and a groove is opened inside the base plate, a rolling ball is movably connected inside the groove, and a cooling port is opened on one side of the base plate, and an electric push rod is fixedly connected to the inside of the sintering furnace body.

[0008] Preferably, a sealing door is rotatably connected to one side of the placement groove, and a sealing ring is fixedly connected to the inside of the sealing door.

[0009] Preferably, a fastener is fixedly connected to one side of the placement groove, and an oxygen display screen is fixedly connected to the bottom of the sintering furnace body.

[0010] Preferably, an alarm light is fixedly connected to the outside of the oxygen display screen, and a temperature display screen is fixedly connected to one side of the sintering furnace body.

[0011] Preferably, a heat dissipation hole is provided on the top of the sintering furnace body, and a filter is fixedly connected inside the heat dissipation hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a filter frame and a mobile cooling mechanism. After the fluorescent powder is placed in the filter frame, the impurities inside the fluorescent powder will be filtered through the fine leak holes inside the filter frame, thereby improving the purity of the fluorescent powder. The traditional sintering device directly sinters the fluorescent powder. The impurities doped inside the fluorescent powder will affect the emission performance of the fluorescent body and the fluorescence intensity. In addition, the filter frame is placed inside the placement tank. After the sintering work is completed, it is not convenient to take it out, which may easily burn the staff. After the sintering is completed, the mobile cooling mechanism can emit cold air through the cooling port. When the sealed door is opened, the high temperature emitted inside the placement tank can be reduced. At the same time, the electric push rod can be started to make the collection frame roll above the rolling ball inside the groove, and the collection tank can be directly pushed out. The staff does not need to put their hands into the placement tank, which is conducive to improving the protection of the staff.

[0014] 2. The utility model can monitor the oxygen content of the equipment in all directions when the device is working by setting up the oxygen display screen and the temperature display screen to avoid excessive oxidation reaction. The temperature display screen can detect the temperature inside the placement tank to avoid excessive sintering temperature. The decomposition of the phosphor will lead to the formation of calcination and crystal defects, which will reduce the luminous effect of the phosphor and affect the subsequent use of the phosphor.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 2 As shown, a nitrogen sintering device for ultraviolet phosphor powder comprises a sintering furnace body 1 and a placing groove 2. The placing groove 2 is opened inside the sintering furnace body 1, and a filter frame 3 is fixed inside the placing groove 2. A garbage collecting frame 4 is fixed at the bottom of the filter frame 3, and a movable cooling mechanism 5 is arranged at the bottom of the collecting frame 4. After the device is powered on, the temperature is concentrated inside the placing groove 2. The filter frame 3 and the collecting frame 4 are connected by a card. The filter frame 3 and the collecting frame 4 constitute a placing mechanism. Multiple groups of placing mechanisms are arranged inside the placing groove 2. The movable cooling mechanism 5 can automatically push the placing groove 2 to the outside of the sintering furnace body 1, so as to facilitate the removal of the phosphor powder nitrogen after sintering.

[0022] like Figure 3-Figure 4 As shown, the movable cooling mechanism 5 includes a bottom plate 501 fixedly connected to the internal position of the sintering furnace body 1, and a groove 502 is opened inside the bottom plate 501, a rolling ball 503 is movably connected inside the groove 502, and a cooling port 504 is opened on one side of the bottom plate 501, an electric push rod 505 is fixedly connected inside the sintering furnace body 1, the bottom plate 501 supports the placement mechanism of the filter frame 3 and the collection frame 4, the grooves 502 are symmetrically distributed about the vertical center line of the bottom plate 501, the rolling balls 503 are equidistantly distributed inside the grooves 502, the cooling port 504 can cool the temperature, and the electric push rod 505 can control the pushing speed of the electric push rod 505 through the control key.

[0023] Furthermore, a sealing door 6 is rotatably connected to one side of the placement groove 2, and a sealing ring 7 is fixedly connected to the inside of the sealing door 6, a fastener 8 is fixedly connected to one side of the placement groove 2, and an oxygen display screen 9 is fixedly connected to the bottom of the sintering furnace body 1, the sealing door 6 is consistent in size with the opening of the placement groove 2, the sealing ring 7 is made of silicone, and after closing the sealing door 6, the fastener 8 is rotated to prevent temperature loss and affect the sintering of the phosphor.

[0024] Furthermore, an alarm light 10 is fixedly connected to the outside of the oxygen display screen 9, and a temperature display screen 11 is fixedly connected to one side of the sintering furnace body 1. The oxygen display screen 9 can detect the oxygen content inside the placement slot 2. Sintering can be started when the oxygen content is qualified to avoid excessive oxygen content, which will cause excessive oxidation reaction and reduce the quality of the material. The temperature display screen 11 can display the internal temperature of the placement slot 2 to avoid excessively high sintering temperature. The decomposition of the phosphor will lead to ashing and the formation of crystal defects.

[0025] Furthermore, a heat dissipation hole 12 is opened on the top of the sintering furnace body 1, and a filter is fixedly connected to the inside of the heat dissipation hole 12. The heat dissipation hole 12 can quickly dissipate the temperature generated inside the sintering furnace body 1 to avoid short circuit of internal equipment due to excessive temperature, which affects the normal operation of the device. The filter prevents dust from entering the inside of the sintering furnace body 1.

[0026] Working principle: When using the ultraviolet phosphor nitrogen sintering device, first place the phosphor on the top of the filter frame 3. The impurities inside the phosphor are filtered through the filter frame 3 and fall into the collecting frame 4. Place the collecting frame 4 in the placement slot 2 inside the sintering furnace body 1, close the sealing door 6, and rotate the fastener 8 to make the phosphor in a sealed state. After confirming the oxygen content and temperature through the oxygen display screen 9 and the temperature display screen 11, start the sintering furnace body 1 to start the sintering of the phosphor. If an abnormality occurs during the sintering process, the alarm light 10 will light up. After the sintering work is completed, open the sealing door 6, start the mobile cooling mechanism 5, and the electric push rod 505 applies pressure to the collecting frame 4. With the assistance of the rolling ball 503 inside the groove 502 opened on the bottom plate 501, the collecting frame 4 is pushed out of the sintering furnace body 1. This is the working principle of the ultraviolet phosphor nitrogen sintering device.
