Description

Technical Field

[0001] The present invention relates to the technical field of ultraviolet phosphor sintering, and particularly to an ultraviolet phosphor nitrogen sintering device. Background Art

[0002] In the fields of modern materials science and optoelectronic technology, ultraviolet phosphors, as an important functional material, have broad application prospects. It can be applied to many fields such as fluorescent display, lighting, biomedical labeling, anti-counterfeiting identification, photocatalysis, and sensors. In order to achieve high performance and stable performance of ultraviolet phosphors, sintering is a key link in its preparation process.

[0003] During the sintering process, the valve ports of the sintering device will face many complex working conditions. On the one hand, since many sintering processes need to be carried out in an inert gas, reducing gas or vacuum environment, the valve needs to be frequently switched and adjusted in different gas environments, which will cause the residual of gas and the deposition of reaction products at the valve port. For example, when using gases such as nitrogen and hydrogen as protective gases or reaction gases, impurities, water vapor or by-products generated by the reaction in the gas will condense or deposit near the valve port. These deposits may come from impurities contained in the gas itself, or substances generated by chemical reactions during the switching between different gases. In addition, the long-term use of the sintering device will cause the blockage and pollution of the valve port due to the entry of dust, particles, etc. in the environment. In some industrial environments, even if certain protective measures are taken, it is difficult to completely avoid the entry of dust, fine metal particles or other impurities into the sintering device, and they will accumulate at the moving parts, sealing surfaces or channels of the valve, thereby affecting the accuracy and reliability of the valve. Summary of the Invention

[0004] The purpose of the present invention is to solve the defect that in the prior art, impurities, water vapor or by-products generated by the reaction in the gas will condense or deposit near the valve port and heat dissipation holes during the sintering process of ultraviolet phosphors, and to propose an ultraviolet phosphor nitrogen sintering device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An ultraviolet phosphor nitrogen sintering device, comprising a box body, wherein a sliding clip bar is fixedly connected to the inner wall of the box body, a notch for the rotation of a sliding gear is opened at one end of the sliding clip bar, a rotating rod is fixedly connected to the side surface of the sliding gear, a first bevel gear is sleeved outside the rotating rod, the first bevel gear is meshed with a second bevel gear, the second bevel gear is drivingly connected with a connecting rod, the connecting rod is drivingly connected with a threaded rod and a third belt, the threaded rod is externally threadedly connected with a first cleaning strip and a second cleaning strip, a heat dissipation hole is arranged above the box body, the third belt is drivingly connected with a third bevel gear, the third bevel gear is meshed with a fourth bevel gear, the fourth bevel gear is drivingly connected with a cleaning strip, a nitrogen valve filter screen is arranged on the side surface of the box body, the rotating rod is drivingly connected with a transmission belt, the rotating rod is meshed with a rack, the rack is fixed at the bottom of the collection tank, and a cooling hole is arranged on one side of the bottom of the box body close to the box door.

[0007] The above technical solution further includes:

[0008] A square groove is opened inside the box body, the inner wall of the square groove is rotationally connected with the rotating rod, the transmission belt is drivingly connected with a first belt, the first belt is drivingly connected with a connecting rod, the connecting rod is rotationally connected to the inside of the box body, the connecting rod is drivingly connected with a second belt, the second belt is drivingly connected with the threaded rod, the fourth bevel gear is drivingly connected with a fourth belt, and the fourth belt is drivingly connected with the cleaning strip. The square groove provides a stable rotational support for the rotating rod, ensuring that the rotating rod can rotate smoothly. The rotating rod serves as a power source and transmits power to the first belt through the transmission belt, thereby driving the connecting rod to rotate. This transmission structure realizes the effective transmission and distribution of power inside the device, enabling the power to be reasonably transmitted to different components. For example, the power is further transmitted to the threaded rod through the connecting rod and the second belt, and to the cleaning strip through the fourth bevel gear and the fourth belt. This enables different components of the entire device to work together, providing a power basis for subsequent operations.

[0009] An oxygen content detection block is fixedly connected to the inside of the box body, and the oxygen content detection block is rotationally connected with the threaded rod. The setting of the oxygen content detection block can monitor the oxygen content inside the box body in real time. During the sintering process of the ultraviolet phosphor, the presence of oxygen may have an adverse effect on the performance of the product because oxygen may react chemically with the phosphor or other substances, affecting the quality and performance of the phosphor.

[0010] A nitrogen control panel is fixedly connected to the side of the box body. The nitrogen control panel is used to control the release of nitrogen from the surface of the nitrogen valve filter screen. The nitrogen control panel provides a convenient operation interface for the operator, enabling precise control of the release of nitrogen from the nitrogen valve filter screen. The operator can adjust parameters such as the flow rate, pressure, and velocity of nitrogen through this panel according to different sintering process requirements. The nitrogen valve filter screen can filter out impurities in the nitrogen, ensuring the purity of the nitrogen entering the box body. The precise control of nitrogen release by the nitrogen control panel helps to create a stable nitrogen atmosphere, prevent the influence of impurities and oxygen on the ultraviolet fluorescent powder, improve the consistency and quality of the product, and ensure the reliability of the sintering process.

[0011] An oxygen content detection panel is fixedly connected to the side of the box body. The oxygen content detection panel is used to control the oxygen content detection block to detect the oxygen content inside the box body. The oxygen content detection panel enables users to conveniently operate and monitor the oxygen content detection block, and facilitates the setting and adjustment of the monitoring parameters of the oxygen content by the users. The user can set an appropriate oxygen content threshold according to needs. When the oxygen content exceeds or is lower than the set range, feedback information can be obtained in a timely manner, and corresponding measures can be taken accordingly.

[0012] A slide rail is provided above the box body, and a protective cover plate is slidably connected to the slide rail. In this embodiment, the slide rail provides a stable sliding track for the protective cover plate, enabling the protective cover plate to slide smoothly above the box body. The protective cover plate can be closed when the equipment is not in use, preventing dust and impurities from entering the inside of the box body, avoiding damage to the internal precision components, and playing a role in protecting the equipment. At the same time, when it is necessary to operate or maintain the inside of the box body, the protective cover plate can be slid open to provide a convenient operation space for the operator, ensuring both the safety and reliability of the equipment and facilitating the daily maintenance and use of the equipment, improving the maintainability of the equipment.

[0013] A box door is rotatably connected to the box body, and a sealing strip is provided on one side of the box door. The box door is conveniently opened and closed by means of rotational connection, providing a convenient operation entrance for the user to facilitate the putting in or taking out of the ultraviolet fluorescent powder from the box body. The sealing strip ensures the sealing performance when the box door is closed, preventing external air from entering the box body, and helping to maintain the stability of the gas environment and temperature environment inside the box body.

[0014] A track for the sliding block to slide is provided on the side of the box body. One end of the sliding block away from the box body is fixedly connected to a cylinder, and an extrusion block for extruding the box door is provided at the output end of the cylinder.

[0015] A groove for containing the ultraviolet fluorescent powder is formed on the surface of the collection tank.

[0016] Both the nitrogen control panel and the oxygen content detection panel are provided with buttons for users to operate.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, after the device is started, the movement of the cleaning strip can remove dust and debris in the heat dissipation holes, ensuring the smoothness of the heat dissipation channel, enabling the device to dissipate heat normally during the subsequent sintering process, and at the same time cleaning the valve filter screen to prevent the accumulation of impurities from affecting the gas flow rate and purity, creating a good heat dissipation and gas environment for the sintering of the phosphor.

[0019] 2. In the present invention, the rack at the bottom of the collection tank meshes with the sliding gear, which will reset the cleaning strip, thus preparing for the next time it is placed in the collection tank. At the same time, the cleaning strip will rotate in the reverse direction to clean the nitrogen valve filter screen, thereby preventing blockage and ensuring that the nitrogen output concentration can reach the expected value.

[0040] In one embodiment, a box door 8 is rotatably connected to the box body 1, and a sealing strip 9 is provided on one side of the box door 8.

[0044] In one embodiment, operation buttons for users are provided on the surfaces of both the nitrogen control panel 2 and the oxygen content detection panel 3.

[0045] The working principle of an ultraviolet phosphor nitrogen sintering device in the present invention is as follows: First, the phosphor to be sintered is filtered and placed inside the collection tank 15. Then, the box door 8 is rotated to fit against the side wall of the box body 1. At this time, the sliding block 4 is slid closer to the side of the box door 8. Then, the air cylinder 5 is started, and the air cylinder 5 pushes the extrusion block 6 to extrude the sealing strip 9. Then, the sealing strip 9 tightly fits against the side wall of the box body 1 by using the box door 8 to prevent air leakage. Then, the collection tank 15 is placed between two groups of sliding clip strips 11. Then, one end of the collection tank 15 just gets stuck between the two groups of sliding clip strips 11. Then, the threaded rod 16 is controlled to rotate. The rotation of the threaded rod 16 drives the second belt 25 to transmit power. The second belt 25 drives the connecting rod 24 to rotate. The connecting rod 24 drives the second bevel gear 22 to rotate by using the first belt 23. The second bevel gear 22 meshes with the first bevel gear 20 to drive the sliding gear 19 to rotate. The sliding gear 19 drives another set of sliding gears 19 to rotate. When two collection tanks 15 are placed between 4 groups of sliding clip strips 11, and there is a rack 13 at the bottom of the collection tank 15, the rack 13 will mesh with the sliding gear 19, so that the collection tank 15 is completely placed inside the box body 1 under the rotation of the threaded rod 16. At the same time, the rotation of the threaded rod 16 will make the first cleaning strip 17 slide to both sides of the top surface of the box body 1 respectively. Then, the rotation of the connecting rod 24 drives the third bevel gear 27 to rotate by using the third belt 26. The third bevel gear 27 meshes with the fourth bevel gear 28 to drive the fourth belt 29 to rotate. The fourth belt 29 further drives the cleaning strip 30 to clean the surface of the nitrogen valve filter screen 31, so as to prevent excessive accumulation of impurities from causing problems with the subsequent nitrogen output volume.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
