Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a melt cooling and forming equipment for producing phosphorus-containing slag microcrystalline glass. Background Technology

[0002] Phosphorus slag microcrystalline glass generally refers to microcrystalline glass prepared using phosphorus slag as the main raw material or one of the raw materials. It is a polycrystalline material that combines a glass phase and a crystalline phase. Phosphorus slag mainly comes from industrial waste generated during the production of yellow phosphorus. The forming methods of microcrystalline glass mainly include sintering, rolling and melting. The sintering method involves first melting the glass raw material and then quenching it into glass granules. Then, the glass granules are loaded into a mold and processed through nucleation, crystallization and other treatments to obtain the product. In industry, the cooling of "molten glass → glass granules" is mainly achieved by water quenching, that is, the high-temperature molten glass liquid is continuously poured into flowing cold water through a flow channel. The melt is in direct contact with the water and is instantly cooled to room temperature to form glass granules.

[0003] However, the cooled granules do not fully meet the requirements for subsequent processing. Although the temperature of the glass granules drops significantly after water quenching, there may be a "temperature gradient" inside granules of different sizes due to the influence of granule size and water quenching process. If processed directly, the residual heat may cause the equipment parts to deform due to heat, or cause microcracks to be generated in the granules due to thermal expansion and contraction during grinding, affecting the density of subsequent sintering. In addition, the glass granules are in direct contact with water and may adsorb impurities and salts in the water. At the same time, there may be some fine particles or other contaminants generated during the crushing process on the surface of the glass granules. If these impurities are not cleaned, they may affect the subsequent sintering process of microcrystalline glass, resulting in problems such as bubbles and reduced purity in the product, thus affecting the performance of the product. Utility Model Content

[0004] The purpose of this invention is to provide a melt cooling and forming equipment for the production of phosphorus-containing slag microcrystalline glass, in order to solve the problems mentioned in the background art, such as the possible existence of a "temperature gradient" inside the granules of different sizes, the direct contact between the glass granules and water, the potential adsorption of impurities and salts in the water, and the possibility of some fine particles or other contaminants generated during the crushing process on the surface of the glass granules.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a melting and cooling molding device for producing phosphorus-containing slag microcrystalline glass, comprising a protective shell with a working groove on its surface, a first feeding roller and a second feeding roller installed on the inner wall of the groove, cooling water nozzle frames fixedly connected to the upper and lower surfaces of the groove, two liquid inlet pipes fixedly connected to the rear surface of the protective shell, two collection grooves formed on the bottom surface of the groove, filter baffles fixedly connected to the inner wall of the collection groove, two drain pipes fixedly connected to the rear surface of the protective shell, two mounting brackets fixedly connected to the inner wall of the groove, air nozzle connecting brackets provided on the surface of the mounting brackets, air inlet pipes fixedly connected to the side surface of the air nozzle connecting brackets, and linkage mechanisms provided on both the front and rear surfaces of the protective shell.

[0006] Preferably, both the first and second feeding rollers are rotatably connected to the protective housing. The first feeding roller spans between the two side walls of the protective housing. The second feeding roller includes two symmetrically arranged sections on the side walls of the protective housing with a cavity between them. One end of each section of the second feeding roller is rotatably inserted into the side wall of the protective housing. The first and second feeding rollers are spaced apart. The inner walls of the openings on both sides of the protective housing are designed to be inclined.

[0007] The above technical solution includes a cavity between the two second feeding rollers. This cavity provides flow space for the cooling medium during the glass conveying process, allowing the cooling medium to come into full contact with the glass particles and improving the cooling effect.

[0008] Preferably, the cooling water nozzle holder is correspondingly arranged with the liquid inlet pipe and is connected to the liquid inlet pipe. The two collection slots are located on both sides of the cooling water nozzle holder and the inner wall of the collection slots is inclined. The collection slots are connected to the drain pipe.

[0009] With the above technical solution, the cooling water nozzle holder and the liquid inlet pipe are correspondingly set and connected. This corresponding connection structure can ensure that the cooling water is smoothly transported from the liquid inlet pipe to the cooling water nozzle holder, avoiding water flow blockage or insufficient water supply caused by improper connection. This allows the cooling water to be sprayed out stably and evenly from the nozzle holder, providing sufficient cooling water source for the cooling of glass granules and improving cooling efficiency.

[0010] Preferably, the side of the mounting bracket fits against the inner wall of the groove in the protective shell, the mounting bracket and the jet nozzle connecting structure are rotatably connected, and the air intake pipe penetrates the side surface of the protective shell.

[0011] With the above technical solution, the side of the mounting bracket fits snugly against the inner wall of the groove in the protective shell. This fitting design allows the mounting bracket to be more stably fixed on the protective shell, providing reliable support for the nozzle connection frame and preventing the nozzle connection frame from shaking or shifting due to unstable installation during equipment operation, which would affect the jet cooling effect.

[0012] Preferably, the linkage mechanism includes a first sprocket, which is disposed on the front and rear surfaces of the protective housing. Two second sprockets are disposed on the front and rear surfaces of the protective housing. A linkage cam is fixedly connected to the outer surface of the second sprocket. Two limiting baffles are fixedly disposed on the front and rear surfaces of the protective housing. A support slide rod is installed through the surface of the limiting baffle. A linkage toothed plate is fixedly connected to one end of the support slide rod. An adjusting gear is fixedly connected to one end of the rotating shaft of the jet nozzle connecting frame.

[0013] By adopting the above technical solution, power can be transmitted to the adjusting gear through the transmission of each component of the linkage mechanism, thereby driving the jet nozzle connecting frame to rotate, providing power support for the adjustment of the jet nozzle angle. There is no need to set up an additional independent power device to adjust the jet nozzle angle, which simplifies the equipment structure and reduces the equipment manufacturing cost and maintenance difficulty.

[0014] Preferably, both the first sprocket and the second sprocket are rotatably connected to the protective housing, a transmission chain is provided between the first sprocket and the second sprocket, and the shaft of the first sprocket is fixedly connected to the shaft of the first feeding roller on one side.

[0015] By adopting the above technical solution, a transmission chain is provided between the first sprocket and the second sprocket, and the shaft of the first sprocket is fixedly connected to the shaft of the first feeding roller on one side. When the first feeding roller rotates, it will drive the first sprocket to rotate synchronously, and then transmit the power to the second sprocket through the transmission chain. This realizes the efficient transmission of power from the feeding roller to the linkage mechanism, eliminating the need to set up an additional power source for the linkage mechanism, saving energy, and also making the power transmission of each component of the equipment more coordinated, thereby improving the overall operating efficiency of the equipment.

[0016] Preferably, the limiting baffle and the supporting slide rod are slidably connected, and a spring is connected between the limiting baffle and the supporting slide rod. The surface of the linkage tooth plate is provided with tooth blocks, one end of the adjusting gear penetrates the surface of the protective shell, and the adjusting gear and the tooth blocks of the linkage tooth plate are meshed.

[0017] Using the above technical solution, the limiting baffle and the supporting slide rod form a sliding connection, and a spring connects the two. The sliding connection allows the supporting slide rod to drive the linkage tooth plate to move flexibly, while the spring setting allows the supporting slide rod and the linkage tooth plate to be reset in time after the linkage tooth plate completes the adjustment action, relying on the elastic force of the spring, so as to prepare for the next adjustment, ensuring that the movement of the linkage tooth plate has good flexibility and resetness, and ensuring the continuity of the adjustment process.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the melt cooling and forming equipment for the production of phosphorus-containing slag microcrystalline glass:

[0019] 1. The equipment uses cooling water nozzles on the upper and lower surfaces of the protective shell to precisely connect with the inlet pipe, enabling stable and uniform spraying of cooling water onto the glass granules during transport. This achieves rapid cooling of the glass granules, effectively alleviating the problem of uneven temperature after water quenching and facilitating subsequent rapid processing. Simultaneously, the inclined collection slots on both sides of the bottom surface of the protective shell allow for rapid collection of used cooling water. Combined with the filter baffles on the inner wall of the collection slots, impurities in the water are filtered out, and the water is ultimately recycled through the drain pipe. This significantly reduces cooling water waste, avoids the leakage problems common in traditional equipment, and lowers the difficulty of cleaning the surrounding area.

[0020] 2. In addition to cooling the glass granules and rinsing off surface impurities with cooling water, the equipment is also equipped with an air jet cleaning structure. External cooling gas enters the air jet nozzle connecting frame through an air inlet pipe that penetrates the side surface of the protective shell. When it is sprayed out from the air jet nozzle, it can not only help to further cool the glass granules, but also remove residual cooling water, as well as adsorbed impurities, salts, and fine particles generated during breakage from the surface of the glass granules. This can more comprehensively remove contaminants from the surface of the glass granules, reduce the occurrence of problems such as bubble generation and purity reduction during subsequent microcrystalline glass sintering, and ensure product performance.

[0021] 3. When the first feeding roller rotates to convey glass granules, it drives the coaxial first sprocket to rotate synchronously. The power is transmitted to the second sprocket through the transmission chain, causing the second sprocket to drive the linkage cam on its outer surface to rotate. The linkage cam pushes the support slide rod to slide within the limit baffle. The support slide rod drives the linkage toothed plate to move. The linkage toothed plate meshes with the adjusting gear to drive its rotation, which in turn drives the jet nozzle connecting frame to rotate around the mounting bracket, realizing flexible adjustment of the jet angle and ensuring that the cooling gas acts precisely on the surface of the glass granules. This design not only simplifies the equipment structure and reduces manufacturing costs and maintenance difficulty, but also saves energy by sharing the power source of the feeding roller, making the operation of various parts of the equipment more coordinated and improving the overall operating efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figure 1-6This utility model provides a technical solution: a melting and cooling molding device for producing phosphorus-containing slag microcrystalline glass, comprising a protective shell 1, a first feeding roller 2, a second feeding roller 3, a cooling water nozzle frame 4, a liquid inlet pipe 5, a collection groove 6, a filter baffle 7, a drain pipe 8, a mounting bracket 9, a jet nozzle connecting frame 10, an air inlet pipe 11, a first sprocket 12, a second sprocket 13, a linkage cam 14, a limiting baffle 15, a support slide rod 16, a linkage toothed plate 17, and an adjusting gear 18. The protective shell 1 has a working groove on its surface. The first feeding roller 2 and the second feeding roller 3 are installed on the inner wall of the groove of the protective shell 1. The first feeding roller 2 and the second feeding roller 3 are rotatably connected to the protective shell 1. A cavity is provided between the two second feeding rollers 3. The inner walls of the two side openings are designed with inclination. After the glass granules are loaded into the water-filterable box and enter the working slot of the protective shell 1, the first feeding roller 2 and the second feeding roller 3 rotate around the protective shell 1. The first feeding roller 2 spans between the two side walls of the protective shell 1. The second feeding roller 3 includes two sections symmetrically arranged on the side walls of the protective shell 1 with a cavity between them. One end of each section of the second feeding roller 3 is rotatably inserted into the side wall of the protective shell 1. The first feeding roller 2 and the second feeding roller 3 are spaced apart. The friction between the roller body and the glass granule loading box drives the loading box to move forward stably. The cavity between the two second feeding rollers 3 provides sufficient conveying and subsequent cooling space for the loading box. The inclination openings on both sides of the protective shell 1 ensure smooth entry and exit of the loading box and avoid jamming.

Two drain pipes 8 are fixedly connected to the rear surface of the protective housing 1. Two mounting brackets 9 are fixedly connected to the inner walls of the slotted section of the protective housing 1. The cooling water nozzle holders 4 are correspondingly arranged with the liquid inlet pipes 5 and are connected to each other. The two collection slots 6 are located on both sides of the cooling water nozzle holders 4, and the inner walls of the collection slots 6 are inclined. Connected to the drain pipe 8, the side of the mounting bracket 9 fits against the inner wall of the groove in the protective shell 1. The mounting bracket 9 and the jet nozzle connecting bracket 10 form a rotatable connection. The air inlet pipe 11 penetrates the side surface of the protective shell 1. External cooling water is transported to the corresponding cooling water nozzle bracket 4 through the liquid inlet pipe 5. The nozzle bracket sprays the cooling water evenly on the surface of the glass granules during the transportation process, achieving rapid cooling and rinsing and cleaning of impurities. The used cooling water flows to the collection grooves 6 on both sides under the action of gravity. The inclined inner wall of the groove accelerates the water flow to the drain pipe 8 and collects it. The filter baffle 7 filters the impurities in the water. Finally, the cooling water is recycled and reused through the drain pipe 8.

[0032] The surface of the mounting bracket 9 is provided with a jet nozzle connecting bracket 10. An air inlet pipe 11 is fixedly connected to the side surface of the jet nozzle connecting bracket 10. The linkage mechanism includes a first sprocket 12, which is located on the front and rear surfaces of the protective shell 1. Two second sprockets 13 are located on the front and rear surfaces of the protective shell 1. A linkage cam 14 is fixedly connected to the outer surface of the second sprockets 13. Two limit baffles 15 are fixedly located on the front and rear surfaces of the protective shell 1. A support slide rod 16 is installed through the surface of the limit baffle 15. A linkage toothed plate 17 is fixedly connected to one end of the support slide rod 16. An adjusting gear 18 is fixedly connected to one end of the rotating shaft of the jet nozzle connecting bracket 10. External cooling gas enters the jet nozzle connecting bracket 10 through the air inlet pipe 11 that penetrates the side surface of the protective shell 1 and is sprayed out from the jet nozzle to assist in cooling. At the same time, when the first feeding roller 2 rotates, it drives the coaxial first sprocket 12 to rotate. The first sprocket 12 drives the second sprocket 13 to rotate through the transmission chain. The second sprocket 13 drives the linkage cam 14 on the surface to rotate synchronously.

[0033] Both the front and rear surfaces of the protective housing 1 are equipped with linkage mechanisms. The first sprocket 12 and the second sprocket 13 are rotatably connected to the protective housing 1. A transmission chain is provided between the first sprocket 12 and the second sprocket 13. The shaft of the first sprocket 12 is fixedly connected to the shaft of the first feeding roller 2 on one side. The limiting baffle 15 and the supporting slide rod 16 are slidably connected, and a spring connects the limiting baffle 15 and the supporting slide rod 16. The surface of the linkage gear plate 17 is provided with toothed blocks. One end of the adjusting gear 18 penetrates the surface of the protective housing 1, and the adjusting gear 18 and the toothed blocks of the linkage gear plate 17 form a linkage mechanism. In the meshing connection, during the rotation of the linkage cam 14, the support slide rod 16 is pushed to slide within the limit baffle 15. The spring between the limit baffle 15 and the support slide rod 16 deforms, and the support slide rod 16 drives the linkage tooth plate 17 to move. The tooth blocks on the surface of the linkage tooth plate 17 mesh with the adjusting gear 18, driving the adjusting gear 18 to rotate, which in turn drives the jet nozzle connecting frame 10 to rotate around the mounting bracket 9, realizing the dynamic adjustment of the jet angle. This ensures that the cooling gas is accurately applied to the surface of the glass particles, thereby removing residual cooling water and impurities and ensuring the cooling and cleaning effect.

[0034] Working principle: When using this molten cooling and forming equipment for producing phosphorus-containing slag microcrystalline glass, after the glass granules are loaded into the protective shell 1, the first feeding roller 2 and the second feeding roller 3 rotate to transport the glass granules. Cooling water is sprayed through the inlet pipe 5 to the cooling water nozzle frame 4 to cool and rinse the glass granules. The wastewater is filtered by the collection slot 6 and the filter baffle 7 and then recovered by the drain pipe 8. Cooling gas enters the jet nozzle connecting frame 10 through the air inlet pipe 11 to assist in cooling and clean the cooling water and impurities. At the same time, the first feeding roller 2 drives the first sprocket 12, which drives the second sprocket 13 and the linkage cam 14 to rotate through the transmission chain. The linkage cam 14 pushes the support slide rod 16 to slide on the limit baffle 15, so that the linkage tooth plate 17 drives the adjusting gear 18 to rotate, thereby adjusting the angle of the jet nozzle connecting frame 10, which increases the overall practicality.
