Description

Technical Field

[0001] This utility model relates to the field of quartz tube processing equipment, specifically a forming equipment for processing high-temperature resistant quartz tubes. Background Technology

[0002] Quartz tubes, due to their excellent properties such as high temperature resistance, good chemical stability, and low coefficient of thermal expansion, are widely used in semiconductor, optics, and high-temperature industries. With the development of related industries, higher requirements are placed on the quality, precision, and production efficiency of high-temperature quartz tubes. Traditional quartz tube forming equipment has many problems in processing high-temperature quartz tubes. Heating the quartz sand is a key step in the processing of high-temperature quartz tubes. However, existing technologies have many problems. On the one hand, heating the quartz sand generates a large amount of dust, which not only pollutes the processing environment and increases the risk of respiratory diseases for operators, but may also accumulate inside the equipment, affecting its normal operation and service life. On the other hand, the surface of quartz sand is usually covered with oil, resin, and other organic matter. Under high-temperature conditions, these organic matter decomposes to produce toxic gases such as benzene and formaldehyde. The emission of these toxic gases not only causes serious pollution to the atmospheric environment, but also poses a great threat to the health of operators. Therefore, a high-temperature quartz tube forming equipment is needed to solve the problems existing in the current technology. Utility Model Content

[0003] The purpose of this invention is to provide a molding equipment for processing high-temperature resistant quartz tubes to solve the problem of generating a large amount of dust and toxic gases.

[0005] As a further improvement of this utility model: the heating box is equipped with a plurality of silicon carbide heating rods, and the heating box is equipped with a heat absorption plate, the upper surface of which is provided with a plurality of flow channels.

[0006] As a further improvement of this utility model: the front of the heating box is connected to a conveying pipe, and two sliding grooves are opened on the upper surface of the conveying pipe, and the inner walls of the two sliding grooves are slidably connected to a baffle.

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

[0013] This invention utilizes a centrifugal fan to generate a stable negative pressure within the air supply pipe, allowing hot airflow carrying dust and toxic gases to enter the filter box in an orderly manner. This completely changes the disorderly emission state of traditional equipment, achieving controllable collection of pollutants at the source. Simultaneously, the filter plates within the filter box utilize inertia to intercept dust. Larger dust particles are intercepted due to inertial impact, while smaller particles are blocked through a sieving effect, significantly reducing dust concentration in the processing area and effectively reducing the risk of respiratory diseases. Furthermore, the honeycomb activated carbon adsorption plate, through its porous structure, adsorbs and forms stable complexes when airflow containing toxic gases such as benzene and formaldehyde passes through. Its purification efficiency is significantly better than that of traditional granular activated carbon, ensuring that the concentration of harmful substances such as formaldehyde in the work space is far below occupational exposure limits, providing operators with a safe working environment that meets modern industrial occupational health and safety requirements.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0026] A forming device for processing high-temperature resistant quartz tubes includes a heating chamber 1, which provides a heating environment for the melting process of quartz sand and is the core component of the device. A centrifugal fan 10 is installed behind the heating chamber 1 to extract the hot airflow from the heating chamber 1, helping to remove dust and harmful gases. A filter box 20 is installed behind the heating chamber 1. The input end of the centrifugal fan 10 is connected to a gas delivery pipe 9, which connects the heating chamber 1 and the filter box 20, for transmitting the hot airflow and harmful gases. The end of the gas delivery pipe 9 furthest from the centrifugal fan 10 is connected to the heating chamber 1. The outer surface of the filter box 20 is connected to the output end of the centrifugal fan 10. The filter box 20 is equipped with a filter plate 22, which is located inside the filter box 20 and is used to filter dust. The filter box 20 is also equipped with a honeycomb activated carbon adsorption plate 23, which is located inside the filter box 20 and is used to adsorb toxic gases generated by the high-temperature decomposition of oil stains, resins and other organic matter on the surface of the quartz sand. The outer surface of the filter box 20 is connected to an exhaust pipe 21, which is used to discharge the filtered gas to the outside of the equipment. The back of the filter box 20 is hinged with a door 19.

[0027] In this embodiment, the heating box 1 is equipped with multiple silicon carbide heating rods 11 to provide a heat source for melting quartz sand. The heating box 1 is also equipped with a heat absorption plate 18 to absorb and transfer heat to the quartz sand, so that the bottom surface of the quartz sand is heated more evenly. Multiple guide grooves 12 are provided on the upper surface of the heat absorption plate 18 to guide the molten quartz sand into the conveying pipe 3.

[0028] In this embodiment, the front of the heating box 1 is connected to a conveying pipe 3, and two grooves 5 are opened on the upper surface of the conveying pipe 3. The inner walls of the two grooves 5 are slidably connected to a baffle 25, which is used to control the flow of molten quartz sand.

[0029] In this embodiment, a guide plate 4 with small holes is provided on the front of the heating box 1 to guide the molten quartz sand into the molding mold 17 to ensure that the quartz sand is evenly distributed. The end of the conveying pipe 3 away from the heating box 1 is connected to the outer surface of the guide plate 4. A molding mold 17 is provided below the guide plate 4 for forming the quartz tube. A fixing plate 24 is installed on the back of the heating box 1, and the upper surface of the fixing plate 24 is connected to the bottom surface of the filter box 20.

[0030] In this embodiment, the upper surface of the heating box 1 is connected to the feed hopper 2, which is used to add quartz sand to the heating box 1, making it convenient to operate and control the feed amount. The outer surface of the heating box 1 is equipped with a controller 8 to control the entire equipment. Multiple third support legs 13 are welded to the bottom surface of the heating box 1.

[0031] In this embodiment, a support plate 14 is provided on the front of the heating box 1 to provide support for the heating tank 7 and the guide plate 4. Multiple second support legs 15 are welded to the bottom surface of the support plate 14.

[0032] In this embodiment, the upper surface of the support plate 14 is connected to the bottom surface of the molding mold 17. A heating tank 7 is installed on the upper surface of the support plate 14, and a resistance heating wire 16 is installed on the inner wall of the heating tank 7 to preheat the molding mold 17 and prevent it from cracking due to thermal shock.

[0033] In this embodiment, a plurality of first support legs 6 are installed on the upper surface of the support plate 14 to provide stability for the guide plate 4, and the top ends of the plurality of first support legs 6 are connected to the bottom surface of the guide plate 4.

[0034] Working principle: During use, the operator first activates multiple silicon carbide heating rods 11 via controller 8 for preheating. Once the temperature reaches the target, the prepared quartz sand is poured from the feed hopper 2 into the heating box 1. The quartz sand falls onto the heat absorption plate 18, where silicon carbide heating rods 11 are also installed. Simultaneous heating from both above and below melts the quartz sand into a honey-like liquid. After heating, the operator manually removes the baffle 25 from the conveying pipe 3. The liquid quartz sand flows into the conveying pipe 3 through the guide groove 12 of the heat absorption plate 18, and then reaches the guide plate 4. Small holes are evenly distributed on the guide plate 4, with a molding mold 17 positioned below each hole. The molten quartz sand flows into the molding mold 17 through the small holes to complete the process. During the molding process, it is worth noting that the resistance heating wire 16 needs to be activated by the controller 8 to preheat the molding mold 17 before molding to prevent cracking caused by thermal shock. During the heating process, the controller 8 simultaneously starts the centrifugal fan 10 to extract air from the inside of the heating box 1. The hot airflow carries fine dust and harmful gases and enters the filter box 20 through the air supply pipe 9. First, the dust is filtered by the filter plate 22, and then the honeycomb activated carbon adsorption plate 23 adsorbs the toxic gases such as benzene and formaldehyde produced by the high-temperature decomposition of organic matter such as oil stains and resin on the surface of the quartz sand. The filtered gas is discharged through the exhaust pipe 21. The staff needs to open the box door 19 regularly to clean the impurities on the filter plate 22 and the honeycomb activated carbon adsorption plate 23 inside the filter box 20.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
