Description

Technical Field

[0001] This utility model belongs to the field of glass production technology and relates to a display glass production kiln. Background Technology

[0002] Glass is a hard but brittle transparent material without a definite melting point. It is usually made by mixing raw materials such as quartz sand, limestone, and soda ash. OLED carrier glass is a type of glass, commonly used in display screens. Glass furnaces are used to melt raw glass materials into molten glass, which is then shaped.

[0003] A Chinese utility model patent with publication number CN221335355U discloses a glass production furnace comprising a base plate, a furnace body fixedly mounted on the top of the base plate, burners fixedly mounted on both sides of the top of the base plate, a sieving box fixedly mounted on the top of the furnace body and connected to the furnace body, a feed inlet at the top of the sieving box, a discharge outlet at one side of the bottom of the furnace body, a sieving frame inside the sieving box, a driving structure on one side of the sieving box, and a guide structure on the inner wall of the sieving box to drive the sieving frame to reciprocate up and down.

[0004] The existing technology has the following technical defects:

[0005] When using the above technical solution, if the glass powder contains large particles, these large particles may adhere to the screen holes and cause blockage. With prolonged use, the screen holes of the screening frame may become blocked, which will prevent the material from passing through smoothly and reduce the screening efficiency. Utility Model Content

[0006] The technical problem this invention aims to solve is that during use, glass powder is screened through a sieve frame. If the glass powder contains large particles, these large particles may adhere to the sieve holes, causing blockage. With prolonged use, the screening holes of the sieve frame may become blocked, which will prevent the material from passing through smoothly, thereby reducing screening efficiency.

[0007] The display glass production furnace of this utility model includes a furnace body, on which a feeding cover plate is installed. A screening component and a crushing component are connected to the feeding cover plate. The screening component includes a screening box connected to the feeding cover plate. The crushing component includes a grinding box and a feeding box. The grinding box is connected to the screening box. The feeding box is installed on the top of the grinding box. A drive shaft is rotatably connected to the top of the feeding box. A grinding roller is installed at one end of the drive shaft inside the grinding box. Grinding grooves are formed inside the grinding box. The grinding grooves are correspondingly connected to the grinding gears on the grinding roller. A first servo motor is installed on the top of the grinding box. The output shaft of the first servo motor is connected to a first screw. A dispersing component is installed at the bottom of the drive shaft. Spiral blades are installed on the drive shaft.

[0008] The screening box contains a screening plate and a second servo motor. A first screw and a first slide rod are rotatably and fixedly connected inside the screening box. The output shaft of the second servo motor is connected to one end of the first screw. The first screw and the first slide rod are threadedly and slidably connected to a drive slider. The two drive sliders are rotatably connected to the same connecting shaft. Several rotating parts are installed on the connecting shaft. A first rack is installed on the screening box, and a first gear is installed on the connecting shaft. The first gear meshes with the first rack.

[0009] The rotating component includes a rotating roller mounted on a connecting shaft, and three cleaning brushes and a cleaning plate are mounted in a ring on the rotating roller.

[0010] The dispersing component includes a fixed column connected to the bottom of the drive shaft, on which six dispersing rods are mounted. The fixed column drives the six dispersing rods connected to it to rotate. The rotating dispersing rods disperse the raw materials that have fallen from the grinding process, so that the raw materials are evenly dispersed onto the screening plate, thereby indirectly improving the screening effect of the screening plate.

[0011] The feed box is equipped with a feed pipe, the furnace body is equipped with a discharge pipe, and the discharge pipe is equipped with a control valve.

[0012] The screening box is equipped with a waste discharge trough, and a control box door is installed on the waste discharge trough. The control box door on the waste discharge trough can be easily opened and closed, facilitating maintenance and cleaning.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses the grinding roller on the crushing component to grind the glass raw material, ensuring that the raw material particles are of uniform size, which is beneficial to the subsequent screening process. In conjunction with the dispersing rod on the dispersing component, the ground raw material can be evenly dispersed onto the screening plate, thereby effectively reducing the adhesion and clogging of large particles on the screen holes. At the same time, it ensures the continuity and efficiency of the screening process and reduces the problem of reduced screening efficiency caused by screen hole clogging in traditional screening frames.

[0015] The first screw is driven to rotate by the second servo motor, which causes the drive slider to move the connecting shaft and the rotating roller on it horizontally above the screening plate. At the same time, the connecting shaft rotates under the action of the first rack, which in turn drives the rotating roller to rotate. This allows the cleaning brush and cleaning plate on the rotating roller to continuously squeeze and spread the raw material on the screening plate, thereby effectively dispersing and screening the raw material and significantly improving the screening efficiency.

A second servo motor 39 is installed on the screening box 31. The first screw 33 and the first slide rod 34 are rotatably and fixedly connected inside the screening box 31. The output shaft of the second servo motor 39 is connected to one end of the first screw 33. The first screw 33 and the first slide rod 34 are threadedly and slidably connected to the drive slider 35. The two drive sliders 35 are rotatably connected to the same connecting shaft 36, and several spiral blades are installed on the connecting shaft 36. The rotating component includes a first rack 4 mounted on the screening box 31, and a first gear 38 mounted on the connecting shaft 36, which meshes with the first rack 4.

The dispersing component includes a fixed column 581 connected to the bottom of the drive shaft 54, with six dispersing rods 582 mounted on the fixed column 581. The fixed column 581 drives the six dispersing rods 582 to rotate, and the rotating dispersing rods 582 disperse the raw materials that have fallen after grinding, ensuring that the raw materials are evenly dispersed onto the screening plate 32, indirectly improving the efficiency of the screening plate 32. 2. Screening effect; The feeding box 51 is equipped with a feeding pipe 6, the furnace body 1 is equipped with a discharge pipe 7, and the discharge pipe 7 is equipped with a control valve 8; The screening box 31 is provided with a waste discharge trough 10, and a control box door 11 is installed on the waste discharge trough 10. The control box door 11 on the waste discharge trough 10 can be easily opened and closed, which is convenient for maintenance and cleaning; The grinding tooth groove 57 is not meshed with the grinding gear on the grinding roller 56, but only overlaps with the protrusion of the grinding tooth groove 57 on the inner wall of the grinding box 52. Although the structure of the grinding tooth groove 57 and the grinding roller 56 is not a meshing connection in the traditional sense, but achieves grinding through overlap, it can still effectively crush large glass raw materials into small particles.

[0024] Working process or working principle:

[0025] During operation, glass raw materials are fed into the feeding box 51 through the feeding pipe 6 via an external feeding structure. The first servo motor 53 then drives the drive shaft 54 ​​to rotate on the feeding box 51, which in turn drives the spiral blades 55 to rotate. The bottom of the feeding box 51 is funnel-shaped. The rotating spiral blades 55 carry the raw materials into the grinding box 52. Simultaneously, the drive shaft 54 ​​drives the grinding roller 56 to rotate. The grinding roller 56 further grinds the raw materials entering the grinding box 52 through the corresponding grinding grooves 57 within the grinding box 52, thus grinding the glass... Large particles in the glass raw material are crushed into small particles that can be screened by the screening plate 32. The ground raw material falls onto the screening plate 32 through the grooves at the bottom of the grinding box 52 and on the screening box 31. The drive shaft 54 ​​drives the grinding roller 56 to grind and simultaneously drives the dispersing rod 582 on the dispersing component to disperse the ground raw material onto the screening plate 32. Then, the rotating roller 371 on the screening assembly screens the raw material on the screening plate 32. The grinding of the glass raw material by the grinding roller 56 on the crushing assembly ensures that the raw material particles are of uniform size, which is beneficial to the subsequent screening process. This is in conjunction with the dispersing component. The dispersing rod 582 can evenly disperse the ground raw material onto the screening plate 32, thereby effectively reducing the adhesion and clogging of large particles on the screen holes. The dispersing rod 582 on the dispersing component disperses the raw material onto the screening plate 32, and then the second servo motor 39 drives the first screw 33 to rotate. The first screw 33 rotates on the screening box 31, driving the drive slider 35 threadedly connected to it to move horizontally. The drive slider 35 drives the connecting shaft 36 and its rotating roller 371 connected to it to move horizontally above the screening plate 32. The other end of the connecting shaft 36... The drive slider 35 slides synchronously on the first slide bar 34. While the connecting shaft 36 moves, it drives the first gear 38 connected to it to rotate on the first rack 4, which in turn drives the connecting shaft 36 to rotate on the drive slider 35, thereby driving the rotating roller 371 to rotate. The rotation of the rotating roller 371 drives the three cleaning brushes 372 and the cleaning plate 373 connected to it to rotate. The rotating cleaning brushes 372 squeeze the raw material out of the screening plate 32 for screening, improving the screening efficiency. The rotating cleaning plate 373 spreads the raw material flat on the rotating plate, reducing the accumulation of raw material in one place when it comes down.
