Description

Technical Field

[0001] This utility model relates to the field of fused silica processing technology, and in particular to a fused silica drying device. Background Technology

[0002] Fused silica is an amorphous form of quartz with a long-range disordered atomic structure. Its unique physical and chemical properties are provided by the cross-linking of its three-dimensional structure. It is a typical glass material with high operating temperature, low coefficient of thermal expansion, and extremely high thermal shock resistance. During the processing of fused silica, drying is necessary to prevent moisture and other volatiles from affecting its quality and performance in subsequent processing.

[0003] In traditional fused silica drying processes, a large number of stacked fused silica are loaded into a drying device and dried by high-temperature heating. This results in uneven drying. At the same time, fused silica is brittle, and direct high-temperature heating can cause sudden temperature changes and uneven heating, which may lead to stress concentration inside the fused silica and increase the risk of cracking.

Two second guide seats are respectively installed between the corresponding conveyor belts. The drive structure is installed on the housing and connected to the conveyor belts.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The fused silica drying apparatus of this utility model is described below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the fused silica drying device of this utility model embodiment includes a shell 1, a feed square tube 2, a preheating feed mechanism 3, a conveying mechanism 4, and a drying mechanism 5.

[0024] The feed square tube 2 is inserted into the top of the housing 1, and a first guide seat 11 is provided at the bottom of the feed square tube 2. The first guide seat 11 is located inside the housing 1, and a second guide seat 12 is provided on both sides of the inner wall of the housing 1.

[0025] It should be noted that the first guide seat 11 is located at the bottom of the feed square tube 2 and has a trapezoidal structure. It mainly serves to guide and buffer the molten quartz, reducing the impact caused by the falling molten quartz. The second guide seat 12 has the same function as the first guide seat 11 and is mainly used to guide the molten quartz between the conveying mechanisms 4.

[0026] The preheating feeding mechanism 3 is installed on the feeding square tube 2. The preheating feeding mechanism 3 includes an inclined support 31, two preheating heating plates 32 and a material control structure 33.

[0027] The inclined support 31 is installed inside the feed square tube 2, and two preheating heating plates 32 are respectively installed on the feed square tube 2 and the inclined support 31. The material control structure 33 is installed on the feed square tube 2 and located on one side of the inclined support 31.

[0028] It should be noted that the inclined support 31 guides the molten silica, and at the same time, the inclined support 31 lowers the space at the bottom of the feed square tube 2, adjusts the discharge amount of molten silica, and avoids a large amount of molten silica material accumulating together. At the same time, the preheating plate 32 is set to preheat the molten silica at a lower temperature to avoid rapid temperature changes during subsequent heating and drying, which could lead to stress concentration and cracking. The material control structure 33 can further control the outflow of molten silica and can also expand the bottom area in case of blockage to solve the blockage problem.

[0029] The material conveying mechanism 4 is located inside the housing 1 and includes three sets of conveyor belts 41 and a drive structure 42.

[0030] The three sets of conveyor belts 41 are respectively arranged vertically inside the housing 1, and the two second guide seats 12 are respectively arranged between the corresponding conveyor belts 41. The drive structure 42 is arranged on the housing 1 and connected to the conveyor belts 41.

[0031] It should be noted that the three sets of conveyor belts 41 work together with the second guide seat 12 to transport molten quartz from top to bottom, thereby increasing the time the molten quartz spends in the drying device and thus improving the drying effect. The drive structure 42 controls the three sets of conveyor belts 41, allowing the molten quartz to be transported in a "Z" shape along the three sets of conveyor belts 41, and finally discharged from the device after drying.

[0032] The drying mechanism 5 is mounted on the housing 1 and is connected to its interior.

[0033] It should be noted that the drying mechanism 5 is connected to the shell 1 and can heat the inside of the shell 1 to dry the molten quartz inside.

[0034] Among them, a guide roller shaft 311 is rotatably mounted on the inclined support 31.

[0035] It is understandable that the guide roller shaft 311 has rotational properties, and a servo motor can be added to control its rotation. The rotation can guide the downward conveying of molten quartz, preventing the molten quartz from getting stuck together and failing to feed downward normally.

[0036] Specifically, when drying fused silica, fused silica is fed into the housing 1 through the feed square tube 2. The fused silica is guided into the housing 1 by the inclined support 31 and the guide roller shaft 311 on it. The preheating plate 32 is operated simultaneously to preheat the fused silica to avoid internal stress. When the fused silica is discharged too quickly and accumulates, the material control structure 33 can be operated to reduce the flow rate of the fused silica and avoid the problem of accumulation.

[0037] After the molten quartz enters the shell 1, it is guided by the first guide seat 11 to the top conveyor belt 41. The relevant personnel operate the drive structure 42 to drive the conveyor belt 41 to run, and at the same time start the drying mechanism 5 to increase the internal temperature of the shell 1 to dry the molten quartz. Under the guidance and transport of the three sets of conveyor belts 41 and the second guide seat 12, the molten quartz is dried and finally discharged from the shell 1 for recycling and subsequent processing.

[0038] In one embodiment of this utility model, such as Figure 2 As shown, the material control structure 33 includes an adjustment groove 331, an adjustment plate 332, and a first driver 333.

[0039] The regulating groove 331 is opened on the feed square tube 2, the regulating plate 332 is rotatably disposed in the regulating groove 331, and the first driver 333 is disposed on the feed square tube 2 and connected to the regulating plate 332.

[0040] It should be noted that the first driver 333 is a servo motor connected to the adjustment plate 332, which can drive the adjustment plate 332 to swing within the adjustment groove 331 and the feed square tube 2. By swinging the adjustment plate 332, the size of the space at the bottom of the feed square tube 2 is changed, thereby controlling the flow rate of molten quartz.

[0041] Specifically, when controlling the flow rate of fused silica, the relevant personnel operate the first driver 333 to drive the regulating plate 332 to rotate. When the plate swings towards the inside of the feed square tube 2, it reduces the internal space, lowers the flow rate of fused silica, and prevents accumulation. When the plate swings towards the regulating tank 331, it raises the bottom space of the feed square tube 2 and accelerates the flow rate of fused silica.

[0042] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the drive structure 42 includes six shafts 421, a fixed box 422, three gears 423, and a second driver 424.

[0043] Among them, six shafts 421 are respectively arranged on both sides of the corresponding conveyor belts 41, the fixed box 422 is arranged on the housing 1, three gears 423 are respectively rotatably arranged in the fixed box 422 and meshed with each other, the three gears 423 are respectively connected to the corresponding shafts 421, and the second driver 424 is arranged on the fixed box 422 and connected to the gears 423.

[0044] It should be noted that the second driver 424 can be a servo motor, connected to one of the three gears 423. By controlling the rotation of one gear 423, the other two gears 423 are driven to rotate, thereby controlling the shaft 421 to drive the conveyor belt 41 to move, realizing the conveying of fused quartz. The fixed box 422 is used to install and fix the above components.

[0045] Specifically, during the drying process, the conveyor belt 41 continuously transports molten quartz, ensuring that the molten quartz falling on it is evenly and in small quantities, avoiding large accumulation. The relevant personnel operate the second drive 424 to drive the gears 423 to drive each other, and drive the shaft 421 to drive the conveyor belt 41 to transport molten quartz in three layers.

[0046] In one embodiment of this utility model, such as Figure 3 As shown, the drying mechanism 5 includes three internal heating plates 51, a heating structure 52, and a water vapor condenser 53.

[0047] The three internal heating plates 51 are respectively installed on the housing 1 and are respectively inserted into the corresponding conveyor belts 41. The heating structure 52 is installed on one side of the housing 1, and the water vapor condenser 53 is installed on the other side of the housing 1.

[0048] It should be noted that the internal heating plate 51 is set inside the conveyor belt 41, which can heat and dry the side of the molten quartz that is in contact with the conveyor belt 41, thereby improving the drying uniformity. The heating structure 52 heats the entire interior of the shell 1, contacting all surfaces of the molten quartz for drying. The water vapor condenser 53 may include an air guide hole, a filter screen, and a condenser. The air guide hole and filter screen ensure the airflow inside the equipment, which is convenient for cooperating with the heating structure 52. At the same time, the condenser can condense and recover the blown water vapor, preventing water vapor from re-entering the shell 1 and contaminating the molten quartz.

[0049] To clearly illustrate the previous embodiment, in one embodiment of this application, such as Figure 3 As shown, the heating structure 52 includes a fan 521 and an electric heating wire mesh 522.

[0050] The fan 521 is located on one side of the housing 1 and is connected to the housing 1, while the electric heating wire mesh 522 is located on one side of the fan 521 and inside the housing 1.

[0051] Understandably, the blower 521 draws in dry air and heats it in conjunction with the electric heating wire mesh 522, then sends the heated air into the housing 1 to dry the molten quartz.

[0052] Specifically, during the drying process, relevant personnel operate the internal heating plate 51, fan 521, and electric heating wire mesh 522 to heat and raise the temperature inside the shell 1, thereby drying the molten quartz. The water vapor generated during drying is blown into the water vapor condenser 53 by the fan 521 for condensation and recovery, ensuring the drying effect of the molten quartz.

[0053] In summary, the fused silica drying device of this utility model can ensure uniform drying of fused silica and prevent internal stress concentration due to sudden temperature changes, thereby reducing the risk of fused silica cracking.
