Abstract
Description
Technical Field
[0001] This application relates to the technical field of glass forming, and particularly relates to a pot for glass forming. Background Art
[0002] Traditional pots for drop feeding and forming are used in the production of lamp cups and bottle jars. The pot consists of structures such as a homogenizing cylinder, a punch, a material pool, a burner, and a material bowl. The homogenizing cylinder and the punch are generally made of refractory materials. The working process of the pot is as follows: The glass liquid continuously flows into the material pool, the burner sprays flames to maintain the temperature of the glass in the pot, the homogenizing cylinder rotates and stirs to eliminate unevenness of the incoming glass, the punch reciprocates up and down according to set process parameters to eject the glass liquid from the mouth of the material bowl for feeding, the shearing machine below the pot cuts the glass column at the mouth of the material bowl to obtain a material drop with a suitable weight, and the material drop is led into the mold through a chute and a guide tube, and then the pressing operation is carried out.
[0003] Since both the homogenizing cylinder and the punch of the traditional pot are made of refractory materials, the cost is relatively high, and erosion will occur after long-term high-temperature use. Its service life is generally only 3 - 5 months. As the stirring effect of the homogenizing cylinder weakens, it will affect the homogenization effect of the glass, and the refractory materials entering the glass liquid will also cause impurities in the glass or affect the transmittance. During this period, the quality of the material drop decreases, and its weight will fluctuate with the erosion of the homogenizing cylinder and the punch, affecting the weight and quality of the material drop.

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0028] Referring to the attached Figure 1 - attached Figure 4 , the embodiment of the present application provides a pot for glass forming, including: a pot body 4, a punch 1, and a heating component 2, wherein: the pot body 4 is used to hold the glass liquid 3, and a discharge port 41 is arranged at the bottom of the pot body 4; the heating component 2 is used to heat the glass liquid 3; the punch 1 is used to punch out the glass liquid 3 from the discharge port 41, a stirring blade 12 is arranged on the punch 1, and the material of the punch 1 is molybdenum.
[0029] In this embodiment, compared with the traditional pot, the structure of the material leveling cylinder is cancelled, avoiding the erosion phenomenon of the material leveling cylinder at high temperature. While optimizing the structure, the material of the punch 1 is designed to be molybdenum, which has a lower cost than platinum. And a stirring blade 12 is arranged on the punch 1, which can ensure the homogenization effect of the glass liquid 3, avoid the influence on the weight and quality of the supplied material drops, and effectively improve the quality of the material drops.
[0030] It should be noted that during the specific implementation process, the punch 1 will be connected to other mechanical transmission structures to achieve rotation and reciprocating movement. For example, in the attached Figure 1In this case, the frit 3 is heated in the basin body 4 by the heating component 2. According to the process-set parameters, the punch 1 moves up and down reciprocally for feeding. The change formed by the movement of the punch 1 can control the weight of the dropped material, enabling the frit 3 to continuously rush out from the discharge port 41. Cooperating with the scissors to obtain appropriate material drops, during the reciprocating movement, the punch 1 also rotates on its own. During the rotation, the stirring blades 12 provided thereon increase the stirring contact surface, making the homogenization effect of the glass liquid better.
[0031] When forming glass material drops by traditional methods, the consistency of the material drop weight is ensured by controlling the temperature of the glass in the basin and the opening degree between the homogenizing cylinder and the bottom of the material pool. Burners are arranged on both sides at the top of the basin to heat the glass in the basin. Sometimes, holes are drilled in the upper part of the homogenizing cylinder and flame heating is used to improve the temperature consistency of the glass inside and outside the homogenizing cylinder. Using flame heating to control the temperature of the glass in the basin has the following several disadvantages: First, the temperature of flame radiation heating fluctuates with the size of the gas pressure, which will lead to instability of the material drop weight and material quality, and the weight accuracy of the material drops is poor (fluctuating ±3 - 5 g); second, flame heating accelerates the volatilization of glass components, and it is easy to form volatilized matter stones at the three-phase junction of the basin; third, although holes are drilled in the homogenizing cylinder, there is still a phenomenon of uneven temperature of the glass inside and outside the homogenizing cylinder in flame radiation heating.
[0032] Therefore, in the embodiments of the present application, the method of heating with electrode rods is adopted. As shown in Attachment Figure 1 and Attachment Figure 2 shown, the heating component 2 includes molybdenum electrode rods 22. The molybdenum electrode rods 22 are vertically inserted into the glass liquid 3 by plugging and directly energized for heating. Changing from flame radiation heating to Joule internal heating of energized heating can stably control the glass temperature. Moreover, the cost of the molybdenum electrode rods 22 is lower than that of the platinum plate electrodes used in some existing technologies. It can reduce costs as much as possible while ensuring normal operation. And under the control of an automatic control device, the glass temperature will be more stable, which can ensure the weight accuracy of the feeding material drops. In addition, the molybdenum electrode rods 22 are installed in a vertically inserted manner, and the installation and replacement operations are simple, hardly affecting production.
[0033] Furthermore, to ensure that the effect of energized heating can be more balanced, as shown in Attachment Figure 2 shown, multiple molybdenum electrode rods 22 are provided. For example, in Attachment Figure 2 A is a group of electrode rods and B is a group of electrode rods. The multiple molybdenum electrode rods 22 are arranged around the axis of the discharge port 41 so that the molybdenum electrode rods 22 can surround the inside of the entire basin body 4 to heat the glass liquid 3.
[0034] In one embodiment, as shown in Attachment Figure 1 and Attachment Figure 4As shown, the heating assembly 2 further includes a water jacket 21. One end of the water jacket 21 is connected to the molybdenum electrode rod 22, and the other end of the water jacket 21 is used to connect to the cooling water circuit, so as to realize the external access of cooling water. The water jacket 21 and the molybdenum electrode rod 22 are connected by screw threads to achieve quick disassembly and assembly. It should be noted that in this way, the joint between the water jacket 21 and the molybdenum electrode rod 22 needs to be immersed below the liquid level in the furnace top brick hole to avoid the oxidation of the molybdenum electrode.
[0035] In one embodiment, as shown in the appendix Figure 3 As shown, the stirring blade 12 is in a collar structure. The stirring blade 12 is close to the head 13 of the punch. The head 13 of the punch is also the end close to the discharge port 41 during the reciprocating motion. The punch 1 can be made of low-oxygen and low-carbon molybdenum. In other embodiments, the main shaft of the punch 1 is coated with a precious metal layer. For example, the main shaft of the punch 1 can be made of molybdenum coated with platinum or other precious metals. During the working process, the homogenization of the glass liquid 3 is driven by the stirring blade 12. In other embodiments, the stirring blade 12 can also be designed in the form of a fan blade, a screw or a frame structure, but there may be a relatively large moving resistance compared with the collar structure form, and there may also be more surplus materials on the stirring blade 12. Further, in order to enhance the stirring effect, multiple groups of stirring blades 12 are arranged along the axis of the punch, and the stirring blades 12 are all arranged at positions close to the head 13 of the punch to avoid affecting the up and down reciprocating movement. In actual use, generally 2-4 groups are designed according to the depth of the material pool inside the material basin body 4. The head 13 of the punch can be set in an umbrella structure, as shown in the appendix Figure 1 and the appendix Figure 3 As shown, the size of the punch head is expanded to enable it to better assist in discharging, and the head 13 of the punch and the main shaft of the punch are connected by detachable screw threads, which is convenient for disassembling and replacing punch heads of different sizes.
[0036] In one embodiment, as shown in the appendix Figure 1 and the appendix Figure 3 As shown, to realize the connection between the material basin and the feeder, a joint 11 is added to the material basin. One end of the joint 11 is connected to the tail of the punch 1 by screw threads, and the other end of the joint 11 is used to connect to the feeder. The joint 11 is made of stainless steel, and an insulating gasket is added to the connection flange with the feeder.
[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
