Description

A kind of preparation method of lead-free and barium-free environment-friendly crystal glass

technical field

The invention belongs to the technical field of glass processing, in particular to a preparation method of lead-free and barium-free environment-friendly crystal glass.

Background technique

Lead oxide (PbO) and barium oxide (BaO) are commonly used components in traditional crystals, which can not only improve the refractive index of glass, but also improve the dispersion rate of glass. In the existing glass formulation, in order to improve the refractive index and dispersion rate, the content of PbO and BaO in the glass composition is often increased. When lead crystal glass products are used, especially the lead dissolved in the use of water utensils, wine utensils and tableware, the lead is very toxic and endangers human health. The barium oxide introduced into the widely developed barium crystal is also a highly toxic oxide. Europe and developed countries have restricted harmful elements such as Pb, Ba, As, Be, Cd, Hg, Sb, Se, Cr, and it is imperative to develop lead-free and barium-free environment-friendly crystal glass formulations. There are similar research reports in China, but it is difficult to achieve the refractive index of high lead crystals without adding lead and barium.

During the processing of crystal glass, it is necessary to crush and grind the relatively large pieces of the raw materials of the glass. The smaller the particles of the raw materials, the faster the melting speed and the better the melting effect in the subsequent melting step. If the ground particles are too small, when the particles are collected, they are easily scattered in the air and are often inhaled into the lungs by workers, thereby causing great damage to the lungs. At the same time, due to the individual size and shape of the raw materials Inconsistent, resulting in long or flaky blocks that cannot pass through the conventional grinder smoothly, and cannot enter the grinding area, resulting in materials that cannot be processed in time, resulting in waste of materials, or because some large materials cannot be ground. There is a certain degree of difference in the ratio of raw materials, which leads to the occurrence of poor quality of the final product. Furthermore, usually the equipment in this area has a large individual structure and a large area, which greatly reduces the walking of workers. Scope is more likely to cause worker injury.

When inside the cavity, the crushing knife will preferentially pre-crumb the raw materials, so as to process the long or sheet-shaped blocks into blocks that are easier to carry out the subsequent grinding stage, so as to avoid the blocks being unable to enter the grinding structure due to the difference in shape. In this way, the utilization rate of the material is increased, and the lack of this component in the final molten product caused by the inability of some raw materials with larger individual shapes and strange shapes to enter the grinding structure, resulting in poor quality of the final product occurs.

Inside, with the continuous movement of the material along the grinding channel, the particles of the material will gradually decrease during the grinding process, and finally fall into the discharge chamber, and finally gather towards the side of the discharge chamber with the inclination of the guide ring. Discharge; through the setting of the third convex tooth and the fourth convex tooth, the transmission is completed through the second gear, so that the speed of the high-speed rotation of the rotating shaft to the rotating block is slowed down, and the rotating speed of the rotating block is relatively slow, but a larger It also reduces the burden on the rotating shaft, reduces the wear of the rotating shaft, and prolongs the service life, and the setting of the dust-proof groove will effectively avoid the dust entering between the rotating shaft and the rotating block. There are gaps, so as to avoid the situation of jamming and reduce the possibility of equipment wear. The material guide ring is an annular block set obliquely, which plays the role of gathering the materials to the discharge port, avoiding the accumulation of materials and causing the utilization rate to decrease. Possibly, through the setting of this structure, the material is carefully ground, thereby effectively reducing the individual material. The reduction of the material individual will effectively facilitate drying, and at the same time, it will effectively facilitate the subsequent melting process and reduce the amount of particles in the melt. It is possible to effectively increase the clarity of the melt, thereby ensuring the quality of the final product.

In the working area, under the grinding of the second grinding teeth, the same as above will be ground to finer sand particles, and then centrifugally move along the second gentle section, and enter the grinding chute, which is inclined from coarse to fine. At this time, the sand grains will be further ground in the structure, and while the grinding action is continuously applied during the rotation process, it provides the centrifugal motion of the material, and the material ground to the final thickness will slide along the blanking material. The groove falls; the large pieces are separated by the first grinding teeth, and the grinding section provided with the first grinding teeth will crush the larger pieces, and the crushed pieces will be moved along the lower edge of the centrifugal motion. It moves along the first gentle section, and the setting of the gentle section provides a certain accommodation space, so that the individual for preliminary grinding can be temporarily stored in the first gentle section. At the same time, the first gentle section is also a screening process, and the individual is still relatively large. The individual will not be able to move outward during the rotation, and will continue to grind under the action of the first grinding tooth. The second grinding tooth is similar to the first grinding tooth, but the second grinding tooth is more advanced than the first grinding tooth. The sharp structure, that is, the first grinding tooth pays more attention to crushing, the second grinding tooth pays more attention to grinding, and the grinding chute in the final stage performs the final grinding of the material.

The iron block enters the fifth cavity, the iron block will be attracted to push the door body, and the first metal block on the door body will be attracted by the electromagnet at the same time, so that the door body will rotate around the first rotating piece, and the electromagnet will start to rotate. When the function of assisting the opening of the door is reached, when the iron block enters the fifth cavity, the power supply is disconnected through the power-off structure at this time, and the door will be closed due to the elastic force of the second elastic member, thereby completing the closure. After the power failure, the electromagnet lost its magnetic force and could not attract the iron block. The iron block fell under the action of gravity and landed at the bottom of the fifth cavity where the door was closed, and then slid down along the fifth cavity. The iron block is discharged from the discharge port; the inclined port is an opening that is opened obliquely, and the inclination angle is opposite to the direction of rotation, so as to avoid the possibility of material accumulation in the inclined port, and the iron-containing raw materials are removed by means of electromagnets. , thereby ensuring that the final glass product can be clear and transparent, avoiding the possibility of yellowing of the glass caused by iron ions, and at the same time, through the setting of the power-off structure, the adsorption effect of the electromagnet is intermittently connected or disconnected, thereby effectively avoiding overheating. The accumulation of a lot of iron ore on the electromagnet leads to the decrease of the final adsorption capacity of the electromagnet, resulting in the inability to remove iron from the subsequent materials, which ensures the cleaning effect of iron in the raw materials, and the timely power-on and power-off method will remove the iron. It effectively helps the discharge of iron blocks, thereby ensuring the clarity of the final glass product.

The power-off structure includes a sixth cavity opened above the fifth cavity, a first magnet block disposed on the rotating block, a second magnet block that can move back and forth in the sixth cavity, and a sixth cavity opened in the sixth cavity.

The second magnet block is continuously attracted or repelled in the form of alternating positive and negative electrodes, so as to control the second magnet block to move back and forth in the sixth cavity. When the second magnet block is located at the proximal end of the sixth cavity , the connection between the electromagnet and the energized block is disconnected. At this time, the electromagnet is no longer connected to the power supply, the electromagnet is non-magnetic, and the iron block adsorbed on the electromagnet will fall down due to gravity. At this time, the other end of the first magnet block, that is, the other pole of the first magnet block is close to the second magnet block. At this time, the second magnet block will slide along the sixth cavity, so that the second magnet block will slide toward the second magnet block. At the distal end of the sixth cavity, the second magnetic block will play the role of connecting the energized block and the electromagnet, and the electromagnet is magnetic at this time; The polarity of the two magnetic blocks realizes the movement of the second magnetic block, so as to use the movement of the second magnetic block as a carrier for switching on and off, effectively realizing the form of intermittent switching on and off.

When the two ends with the highest magnetism of the first magnetic block are close to the second metal block, the second metal block will be in the magnetic field. Under the action, towards the proximal end of the eighth cavity, due to the movement of the second metal block, the fixed block connected to it through the rope body will move upward, and the upward movement of the fixed block will release the fixing of the second magnetic block, and then The second magnet block will move to the opposite end under the action of the first magnet block, and then due to the distance of the first magnet block, the fixed block will move downward, and the second magnet block will move downward through the fixed chute set on it. The block is squeezed to the most corner of the sixth cavity; the first magnetic block attracts the second metal block, so as to control the movement of the fixed block, which has the effect of fixing the second magnetic block, thus effectively ensuring the electromagnetic block. At the same time, through the setting of the fixed chute, when the second magnet block fails to move to the limit position, the fixed block will be pressed down under the action of the first elastic member, thereby pushing the second magnet block to the designated position, Thus, the effect of the second magnetic block as an electrification structure is ensured, the stability of the apparatus is increased, the iron removal effect is effectively ensured, and the final product quality is ensured.

When the molten material needs to be taken out, push the blocking sheet to move inward, and the blocking sheet that moves inward will pass through the second slope and the first. The cooperation between the inclined surfaces pushes the slider to move upward, and the slider that moves upward simultaneously drives the snap block to move upward, and the snap block moves out from the card interface, so that the drawer can be pulled out. When the drawer is pulled out, the push block is lost. The protruding block on the drawer is squeezed, so as to be pushed out under the action of the third elastic member, at this time, the push block will squeeze the airtight part in the eleventh cavity, so that the second engaging block will protrude outward. It is connected to the second card interface to form a fixation for the blocking piece. Only when the drawer is reset, the second snap block will be retracted into the eleventh cavity, and the blocking piece will no longer be limited and can be pulled out. When the drawer needs to be pulled out, the blocking sheet needs to be inserted into the end of the chute, and the fixing of the drawer will be unlocked while closing the communication pipe, and the blocking sheet will be limited and fixed at the same time when the drawer is taken out. The blocking effect of the blocking sheet prevents the material residues above from falling into the bottom, causing accumulation, and melting under the action of high temperature into a block with a certain viscosity, which makes the drawer unable to open and causes damage to the equipment. The setting of the structure ensures that when the drawer is not in the casing, the blocking sheet is always in a closed state. On the one hand, the upper and lower two can work separately without interfering with each other, on the other hand, the loss of materials is avoided, the cost of raw materials is saved, and at the same time Avoid the accumulation of residual material in the device and cause damage to the device.

The glass material of the invention has zero addition of lead and barium, is environmentally friendly, and meets the requirements of environmental protection; the prepared glass has a refractive index (nD≥1.56), a dispersion coefficient (vd≥60), a density (d≥60) similar to high lead crystals 2.94g/cm3), transmittance (t≥88%), good chemical stability.

Among them, in the processing of crystal glass, through the integrated design, the floor area is smaller, which saves the floor space and is more suitable for the production of small batches of high-quality handicrafts. At the same time, the integrated structure directly throws the ground powder into the molten structure. , to prevent the powder from floating in the air, thus ensuring the working environment, avoiding the powder floating in the air and being inhaled by the workers, causing physical damage, thus protecting the health of the workers, and then through the setting of the crushing knife, the raw materials will be given priority.
