Description

[0002] Glass powder is an inorganic cubic hard ultrafine particle powder of Anmi Micro-Nano. It looks like white powder. Quartz powder, borax and other raw materials are used in its production. Through melting, grinding, mixing and other processes, a disordered glass transparent powder is formed.

[0003] The existing glass powder material mixing device includes a mixing box and a mixing component. When in use, the glass powder material is first poured into the mixing box, and after the glass powder material is loaded, the mixing component is started to mix the glass powder material in the mixing box. This glass powder material mixing device has the following disadvantages: 1. The glass powder materials are poured into the mixing box uniformly, resulting in the glass powder materials entering the mixing box being concentrated. In addition, since the mixing operation is started after the glass powder materials are loaded, the subsequent mixing components take a long time to mix the glass powder materials, reducing the mixing efficiency of the entire glass powder materials. 2. Most mixing components adopt a single mixing method, which makes it difficult to cover a large area in the entire mixing box during the mixing process, and easily forms "dead corners", which causes the glass powder materials in these places to be unable to fully participate in the mixing, affecting the mixing effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described in combination with the drawings and embodiments: See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 And attached Fig.10As shown, a material mixing device for glass powder comprises a base 1, an outer shell 2, a mixing box 3, a feed hopper 4, a material guide box 5, a driving assembly 6, a discharge assembly 7, a cover assembly 8 and a mixing assembly 9; wherein the base 1 is of a circular structure and serves as a supporting installation, and is provided with an outer shell 2 of a circular structure; the outer shell 2 is open at the bottom and the top, and is rotatably connected with a mixing box 3 of a circular structure therein, so that the mixing box 3 can rotate circumferentially; the mixing box 3 is open at the top, and is provided with six feed ports 31 on the side circumference, on which the feed hopper 4 is installed; the lower end of the feed hopper 4 is sleeved on the outside of the mixing box 3 and is connected with the feed port 31, so that the glass powder material introduced through the feed hopper 4 flows to the feed port 31, and enters the mixing box 3 from the feed port 31; A material guide box 5 with a circular structure is arranged at the bottom of the mixing box 3, and a material guide pipe 51 is vertically connected to the bottom of the material guide box 5; the material guide pipe 51 is connected to a driving component 6 arranged on the base 1, so that the driving component 6 operates to rotate the mixing box 3; the material guide pipe 51 is also connected to a discharge component 7 arranged on the base 1, so that the discharge component 7 operates to discharge the glass powder material in the mixing box 3 to the outside of the outer shell 2; in addition, a cover component 8 is installed on the outer shell 2, and the cover component 8 is located above the mixing box 3 to seal the top opening of the mixing box 3, and a mixing component 9 is installed on the cover component 8; the mixing component 9 is inside the mixing box 3, and the mixing box 3 drives the mixing component 9 to rotate when it is in a rotating state, so that the mixing component 9 mixes the glass powder material in the mixing box 3.

[0022] In the specific implementation process of the present invention, the staff performs the feeding operation of the glass powder material through the feeding hopper 4, and during the feeding process, the mixing box 3 starts to rotate at a low speed under the action of the driving component 6. At this time, the feeding hopper 4 rotates together with the mixing box 3. When the feeding hopper 4 rotates, the glass powder material entering is affected by the centrifugal force, so that the glass powder material entering the mixing box 3 is dispersed and thrown to the bottom of the mixing box 3, which is helpful to achieve more refined mixing in the subsequent processing process; at the same time, the glass powder material dispersed into the mixing box 3 is stirred at a low speed by the mixing component 9 and starts the preliminary mixing action; when the feeding operation of the glass powder material is completed, the mixing box 3 starts to rotate at a high speed under the action of the driving component 6, and at the same time, the mixing component 9 rotates together with the high-speed rotation of the mixing box 3. The glass powder material is mixed by the rotation of the mixing box 3 and the rotation of the mixing component 9. It not only moves in a circular direction, but also generates an upward or downward flow in the vertical direction, forming a complex three-dimensional flow path, increasing the relative displacement between the glass powder material particles, so that each glass powder material particle has more opportunities to contact and mix with other glass powder material particles. At the same time, this kind of coordination can effectively reduce the mixing dead angle, ensure that the glass powder material in the entire mixing box 3 can participate in the mixing process, and improve the mixing effect; it is worth mentioning that due to the loading process in the front section, the glass powder material has a better dispersion effect, so that the mixing process in the middle section does not need to spend too much time, thereby improving the mixing efficiency of the glass powder material; when the mixing operation is completed, the driving component 6 stops operating, the mixing box 3 and the mixing component 9 no longer move, and at the same time, the discharge component 7 operates to discharge the glass powder material in the mixing box 3 to the outside of the outer shell 2.

[0023] For the above embodiments, refer to the attached Figure 1 As shown, the outer shell 2 includes a fixed shell 21, a movable shell 22 and a bearing 23; the fixed shell 21 is a semicircular structure and a movable shell 22 for acting as a door body is installed at its front end, and a bearing 23 connected to the mixing box 3 is arranged in the fixed shell 21; during the implementation process, by setting the outer shell 2 as a split type and using the movable shell 22 as the door body, subsequent maintenance work on the device is facilitated.

[0024] For the above embodiments, refer to the attached Figure 1 and attached Figure 2As shown, two conical parts 32 are formed at the bottom of the mixing box 3, and a feed pipe 33 connected to the material guide box 5 is installed on each of the two conical parts 32, and a feed valve 34 is installed on each of the two feed pipes 33; during the implementation process, the two feed valves 34 are always kept in a closed state during feeding and mixing, and the two feed valves 34 are automatically opened during feeding, and under the action of the two conical parts 32, the feeding effect of the glass powder material in the mixing box 3 can be greatly improved; the two conical parts 32 can disperse the glass powder material flow and reduce the local pressure during feeding, thereby reducing the possibility of bridging and reducing the retention or accumulation of glass powder materials; and by adopting the double feed pipe 33 design, even if one feed pipe 33 is blocked, the other feed pipe 33 can still continue to work, ensuring continuity; Among them, considering that glass powder material may be lifted up at the feed inlet 31 during the feeding and mixing process, for this reason, refer to the attached Figure 5 -Attached Figure 7 As shown, each feed port 31 is rotatably connected with a baffle plate 35, and the baffle plate 35 can only deflect inwardly, so that the feed port 31 is opened when the baffle plate 35 is pushed inwardly; during the implementation process, the glass powder material will generate an inward thrust on the baffle plate 35 after falling through the feed hopper 4, and at this time the baffle plate 35 will flip inward to open the feed port 31, and the glass powder material will enter the mixing box 3 along the feed port 31. When the mixing box 3 and the stirring assembly rotate at a high speed, the baffle plate 35 will be subjected to centrifugal force, generating an outward deflection force, but at this time, the bottom end of the baffle plate 35 is resisted by the bottom end of the feed hopper 4, so the baffle plate 35 will not flip outward, and in this state, the baffle plate 35 can close the feed port 31 to prevent the glass powder material from overflowing; In addition, considering the sealing effect of the cover assembly 8 on the top opening of the mixing box 3, for this purpose, refer to the attached Figure 8 and attached Fig. 9 As shown, a circle of rubber balls 36 are installed on the top of the mixing box 3 to form a rolling surface on the top of the mixing box 3 that contacts the cover assembly 8; during implementation, the balls 36 can effectively block the distance between the mixing box 3 and the cover assembly 8, and at the same time, will not affect the rotation of the mixing assembly 9 and the sealing operation of the cover assembly 8.

[0025] For the above embodiments, refer to the attached Figure 2 and attached Figure 3As shown, the driving assembly 6 includes a driving motor 61, a main gear 62 and a slave gear 63; the driving motor 61 is arranged on the base 1 and is connected to the main gear 62, and the main gear 62 is meshed with the slave gear 63 arranged on the guide tube 51; during the implementation process, the driving motor 61 operates to rotate the guide tube 51, and then drives the guide box 5 to rotate, and finally causes the mixing box 3 to rotate. During this period, the shaft of the driving motor 61 performs low-frequency motion during the loading stage. When the loading is completed, the shaft of the driving motor 61 starts to rotate at a high frequency, thereby realizing a rapid mixing operation.

[0026] For the above embodiments, refer to the attached Figure 2 and attached Figure 3 As shown, the discharge assembly 7 includes a powder pump 71, a butt joint 72, a rotary joint 73 and a discharge pipe 74; the powder pump 71 is arranged on the base 1 and its feed end is connected to the butt joint 72, the butt joint 72 is connected to the end of the guide pipe 51 through the rotary joint 73, and the discharge end of the powder pump 71 is connected to the discharge pipe 74, the discharge pipe 74 is a hose and extends to the outside of the fixed shell 21; during implementation, due to the setting of the rotary joint, the guide pipe 51 does not affect the use of the butt joint 72 during rotation. When unloading, the operation of the powder pump 71 can ensure that the glass powder material is smoothly discharged from the mixing box 3, avoiding the occurrence of blockage or bridging, and improving the efficiency of unloading. After unloading, the discharge pipe 74 can be used to unload on site or transport the mixed glass powder material over a long distance.

[0027] For the above embodiments, refer to the attached Figure 1 and attached Figure 7 As shown, the cover assembly 8 includes a bracket 81, a telescopic cylinder 82 and a cover plate 83; the bracket 81 is arranged on the fixed shell 21 and is connected to the cover plate 83 through the telescopic cylinder 82, so that the cover plate 83 can rise or fall, the cover plate 83 is located directly above the top opening of the mixing box 3 and contacts with the rolling surface during feeding, mixing and discharging, and a mixing assembly 9 is installed at the bottom of the cover plate 83; during feeding, mixing and discharging, the telescopic end of the telescopic cylinder 82 extends to make the cover plate 83 move down and seal the top opening of the mixing box 3. When the cover needs to be opened, the telescopic end of the telescopic cylinder 82 contracts to drive the cover plate 83 to move up. At this time, the top of the mixing box 3 is opened, which is convenient for cleaning and maintenance operations. Among them, refer to the attached Figure 1 and attached Figure 6As shown, the cover plate 83 has a conical structure so that a large opening loading position with a convex center and a concave outside is formed between the cover plate 83 and the feed hopper 4; during the implementation process, the staff can directly inject the glass powder raw material into the large opening loading position to allow the glass powder raw material to enter the feed port 31. Through this design, when the glass powder raw material is loaded, the glass powder raw material will be dispersed due to collision when it contacts the cover plate 83. At the same time, the dispersed material will fall directly to the feed port 31 along the inclined surface of the cover plate 83, which greatly improves the loading effect.

[0028] For the above embodiments, refer to the attached Fig.10 -Attached Fig.13 As shown, the mixing assembly 9 includes a mounting plate 91, a mounting roller 92, an outer gear 93, an inner gear 94, a rotating rod 95 and a mixing rod 96; the mounting plate 91 is arranged at the bottom of the cover plate 83 and four mounting rollers 92 are arranged on it for circular rotation, each mounting roller 92 is respectively installed with an outer gear 93, each outer gear 93 is meshed with an inner gear 94 arranged inside the mixing box 3, so that the rotation of the outer gear 93 causes the four outer gears 93 to drive the four mounting rollers 92 to rotate, and the bottom end of each mounting roller 92 is respectively connected to a rotating rod 95, and each rotating rod 95 is respectively installed with a plurality of mixing rods 96; during the implementation process, the inner gear 94 rotates with the rotation of the mixing box 3, and the rotation of the inner gear 94 drives the four outer gears 93 to rotate, and finally causes the plurality of mixing rods 96 to rotate in the mixing box 3, and it is worth mentioning that the plurality of mixing rods 96 can mix along multiple positions inside the mixing box 3, which can effectively improve the mixing effect.

[0029] In addition, in order to further improve the mixing effect and efficiency of the glass powder material, so that the contact and mixing effect between the particles of the glass powder material during the mixing process is better, for this purpose, refer to the attached Fig.14 As shown, the mounting plate 91, the mounting roller 92, the rotating rod 95 and the mixing rod 96 are all hollow structures and are interconnected to form an air flow channel, wherein the mounting plate 91 is connected to an air inlet pipe 97, which extends to the outside of the cover plate 83 and is connected to an external air source; during the implementation process, the external air source injects the airflow into the air flow channel through the air inlet pipe 97, and finally the airflow enters the mixing box 3 along the air flow channel, and turbulence can be formed between the glass powder materials through the blowing of the airflow, increasing the relative movement between the glass powder material particles, generating complex flow paths in different directions, increasing the relative displacement between the glass powder material particles, thereby promoting more uniform mixing, and further improving the mixing efficiency.
