Description

Technical Field

[0001] The present invention relates to the technical field of glass particles, and in particular to a manufacturing system for glass particles. Background Art

[0002] The main advantages of glass are its high strength, hardness, elasticity and rigidity. Its strength and hardness are higher than those of existing general crystalline metals, and it has extremely strong corrosion resistance. At the same time, it also has good soft magnetic properties, which makes it have wide application potential in machinery, communications, aerospace, medicine and other fields. In order to obtain granular glass particles, some existing glass materials mostly use preparation equipment with a crucible at the top and a collector at the bottom. The top crucible is equipped with a heating device, which is responsible for melting the injected glass raw materials and discharging the droplets from the bottom by vibrating the transmission rod. Before discharging, inert gas is introduced into the crucible through the crucible inlet pipe to achieve a stable differential pressure of 30kPa between the crucible and the vacuum chamber. The pulse signal is edited by a signal generator and applied to the piezoelectric ceramic. The piezoelectric ceramic generates a small displacement under the drive of the pulse signal and drives the transmission rod to move. This small displacement is caused by the transmission rod to act on the melt at the bottom of the crucible, so that small droplets are ejected from the small hole to form droplets, which are then collected by the collector at the bottom. A patent similar to the above-mentioned prior art, such as Chinese patent application number CN201410346244.5, discloses a method and apparatus for preparing metallic glass particles, which discloses the above-mentioned crucible with heating and discharging functions.

[0003] However, in actual production, we found that when the high-temperature molten glass droplets are directly injected into the collector for traditional collection, they cannot be quickly cooled during the falling process. This will cause the droplets to deform, and the droplets falling behind will adhere to the droplets falling in front of them because they are in a plastic state. If refrigerant gas or coolant is then introduced into the collector to cool them and separate them, their surface quality will not be processed to standard, which will affect the product quality when they are used on carrier products. Summary of the Invention

[0024] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0027] Refer to the attached Figure 1-6A glass particle manufacturing system includes a base 1 and a crucible 2 connected to the top of the base 1 for making glass droplets, the bottom of the crucible 2 is connected to a quartz glass tube 3 for dripping the made glass droplets downward, the crucible 2 is filled with molten metal and is provided with a heating device for heating the molten metal, the heating device includes a heater 18 surrounding the periphery of the crucible 2, a ceramic plate 19 installed at the bottom of the crucible 2 and directly opposite to the bottom of the transmission rod, and a small hole 20 opened on the ceramic plate 19 for dripping the heated glass droplets along the quartz glass tube 3 into the guide track 6 (the above structure of the crucible 2 has been disclosed, see CN201410346244.5, and will not be repeated here. The focus of the present invention is that the quality of the glass particles can be improved by using the base 1).

[0028] A cooling chamber 4 filled with coolant is provided in the base 1, and a cooling pump 28 and a cooling pipe 27 are used to circulate the coolant for cooling (circulating cooling is a prior art and will not be described in detail). A cover plate 5 is provided on the top of the cooling chamber 4. A drop hole 51 communicating with the inner cavity of the cooling chamber 4 is provided on the cover plate 5. A material guide track 6 is installed on the top surface of the cover plate 5 and is a guide cavity structure with two spiral structures. One end of the material guide track 6 is provided with a receiving end 7 that rotates inward to be close to the drop hole 51, and the other end of the material guide track 6 is provided with a receiving end 8 that rotates outward to be close to the outer wall of the cover plate 5. The quartz glass tube 3 mounted on the crucible 2 is vertically downward above the material receiving end 8, so that the glass liquid dripping downward from the quartz glass tube 3 falls into the material receiving end 8. Since the end of the material receiving end 8 of the guide rail 6 is equipped with a carrier plate 9, and the carrier plate 9 is equipped with a cylinder 10, and the action rod of the cylinder 10 passes through the carrier plate 9 and extends into the material receiving end 8, and since a hinge seat 11 is fixed on the inner ring wall of the material receiving end 8, and a push plate 12 corresponding to the action rod of the cylinder 10 is movably connected to the hinge seat 11, and a plurality of downwardly concave balls are provided on the upper surface of the cover plate 5. Therefore, it can be seen that the droplets falling from the quartz glass tube 3 will fall into these spherical shallow grooves 13 and stay temporarily. Since these spherical shallow grooves 13 correspond to the material receiving end 8 of the guide track 6 and are close to the push plate 12, when the action rod of the cylinder 10 is working, the action rod will not only drive the push plate 12 to rotate in the direction of the spherical shallow grooves 13, but also push out the droplets falling in the spherical shallow grooves 13 at the moment of its rotation, and use the impact effect generated at the moment of its rotation to force these droplets to follow the guide track 6 from the drop hole 51. The liquid droplets fall into the cooling chamber 4 at the bottom and are completely cooled and formed. Therefore, the spherical shallow groove 13 is still directly opposite the bottom of the quartz glass tube 3. However, it is well known that the liquid droplets are formed by high-temperature melting in the crucible 2 and are discharged through the small hole 20 (the discharge method is disclosed in the prior art) as semi-fluid molten droplets. When they fall into the spherical shallow groove 13, they still have certain plastic properties. At this time, when the push plate 12 directly pushes them out of the spherical shallow groove 13, it is very likely that they will adhere to the push plate 12 and may also cause them to directly undergo plastic deformation. Therefore, in order to prevent this phenomenon from occurring, in the present invention, as shown in FIG. Figure 5 、 Figure 6As shown, a plurality of cooling holes 14 with openings facing downward and facing the cooling chamber 4 are further provided on the bottom surface of the cover plate 5. The plurality of cooling chambers 4 correspond to the bottoms of the plurality of spherical shallow grooves 13, and an infiltration hole 15 is provided between the cooling chamber 4 and the spherical shallow groove 13 for communicating with the two up and down. A water pump 16 is installed in the cooling chamber 4, and the water inlet pipe of the water pump 16 is located in the cooling chamber 4. The water outlet pipe of the water pump 16 is directly below the cooling hole 14 and is used to spray part of the coolant extracted from the cooling chamber 4 onto the cooling hole 14, and then the coolant is leaked upward into the spherical shallow groove 13 through the infiltration hole 15, thereby forcing the droplets smaller than the outline size of the spherical shallow groove 13 to be pre-cooled to no As for the plastic deformation caused by the subsequent push plate 12, the pre-cooled droplets will have a certain hardness and will not be greatly deformed when pushed by the push plate 12. In addition, the top surface of the guide track 6 is fixed with a sealing plate 24 for covering its inner cavity. When the droplets are pre-cooled and become particles and roll along the guide track 6 into the cooling chamber 4, the sealing plate 24 covers the guide track 6 and will not cause the pre-cooled particles to jump out of the guide track 6. In addition, multiple droplets that fall into the spherical shallow groove 13 at one time will not stick to each other during the process of rolling a long distance along the guide track 6 to the cooling chamber 4 after pre-cooling.

[0029] like Figure 2 As shown, a seepage hole 17 away from the spherical shallow groove 13 is opened on the cover plate 5, so that the coolant sprayed from the bottom into the spherical shallow groove 13 will eventually leak into the cooling chamber 4 through the seepage hole 17.

[0030] like Figure 2 、 Figure 5 As shown: the material guide track 6 includes an outer ring portion 21 located at the outermost side along its vortex profile from the material receiving end 8 and an inner ring portion 22 along its vortex profile until it bends to the material receiving end 7. A tension spring 23 is connected between the push plate 12 and the carrier plate 9 to enable the push plate 12 to return to its original position again when the action rod of the cylinder 10 retracts after pushing the particles. A spring plate 25 is installed at one end of the push plate 12 close to the hinged seat 11. The spring plate 25 extends along the inner wall surfaces of the outer ring portion 21 and the inner ring portion 22 to the middle of the material guide track 6. The inner wall surfaces of the outer ring portion 21 and the inner ring portion 22 are provided with a cavity 26 extending from the material receiving end 8 to the material receiving end 7. The end of the spring plate 25 gradually tilts into the cavity 26. The function of the spring plate 25 is consistent with that of the tension spring 23. Both are used to enable the push plate 12 to effectively return to its original position by utilizing their elastic properties after pushing the particles.

[0031] like Figure 5As shown, a cooling pipe 27 is provided in the cooling chamber 4 of the base 1, and the top end of the cooling pipe 27 corresponds to the bottom of the drop hole 51, and the bottom end of the cooling pipe 27 faces the bottom of the cooling chamber 4. The shape of the cooling pipe 27 is a wave tube with multiple bends from the top downward and a mesh tube made of steel wire mesh. The particles falling from the drop hole 51 into the cooling chamber 4 will fall into the cooling pipe 27, and then slide along the multiple bends of the inner cavity of the cooling pipe 27 for a long distance, and finally fall on the bottom of the cooling chamber 4. In this way, the falling distance of the particle product in the cooling chamber 4 is extended, and the contact time between the particle product and the particles that fell on the bottom of the chamber last time is prolonged, ensuring that they are thoroughly cooled before being accumulated on the bottom of the chamber, and preventing them from sticking to each other and being thoroughly cooled for the last time.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings.
