Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass recycling equipment, and particularly relates to a novel broken glass recycling and transfer device. Background Technique
[0002] As an inevitable product and one of the indispensable raw materials in the production process of glass factories, the recycling and utilization of broken glass have always been taken seriously by each manufacturer. Usually, broken glass and batch (also known as clinker) are sent to the kiln head bin in a certain proportion, and then sent into the kiln through a feeding machine. During the melting process, the broken glass plays a role in promoting the melting of the clinker and reducing energy consumption. It can also increase the melting capacity of the melting furnace and improve the melting quality, and is an essential raw material for producing high-quality glass. Although there are many layout methods for the broken glass recycling system and the operating conditions vary greatly in different places, no matter what kind of recycling method, its purpose is the same, that is, to minimize recycling losses and pollution and reduce operating costs.
[0003] The broken glass recycling method mainly considers factors such as production scale, variety, grade, product color, broken glass composition, control method, etc., and needs to be considered overall in combination with the characteristics of the factory area and the process layout of the production line.
[0004] The quality of broken glass has a certain impact on the appearance quality and internal quality of glass. For example, changes in the composition, oxidation-reduction properties, and particle size of broken glass may cause defects such as bubbles and streaks in the glass, affecting the mechanical and optical properties of the glass. Moreover, poor homogenization of the glass liquid will cause a significant increase in the brittleness of the glass, making the glass brittle and easy to break. These quality defects are unacceptable to users of ultra-thin glass. Therefore, it is necessary to strictly control the particle size, storage environment, and discharging method of broken glass.
[0005] At present, the recycling of broken glass by domestic glass enterprises can be generally divided into the following several forms: one is the manual method. The broken glass first enters the broken glass bin under the production line, is transported to the broken glass yard by a tipping truck, and then is transferred to the bucket elevator or the broken glass inlet of the raw material workshop by a tipping truck according to production needs. After being broken and weighed by a crusher, it is sent to the kiln head bin together with the batch. The second is the manual-assisted type. The broken glass passes through the broken glass bin under the main line, enters the broken glass transfer belt, and then enters the broken glass storage bin through a bucket elevator. Then, like the first method, the tipping machine takes the material from under the storage bin. The third is the full-mechanical conveying. The broken glass first enters the broken glass bin, is sent to the bucket elevator through a belt, the bucket elevator lifts it to the broken glass storage bin, and the weighed broken glass is then sent to the original melting belt through a belt, and then sent to the kiln head bin together with the batch.
[0006] Float glass production lines with high drawing volume basically adopt the full-mechanical conveying or traditional technology mode with manual assistance. Production lines with low drawing volume adopt the manual transfer mode. The design proposed by our company conducts centralized treatment and dust prevention measures for the broken glass in the discharge bin, ensuring that the broken glass flowing through the bin can be cleanly recycled to the kiln head for remelting, and can reduce the loss of broken glass and the introduction of iron into the system. Summary of the Invention
[0007] To solve the problems raised in the above background technology, the present invention provides a new type of broken glass recycling and transfer device, which can reduce the loss of broken glass, reduce the introduction of iron into the system, and reduce dust.
[0008] The present invention provides the following technical solutions:
[0009] A new type of broken glass recycling and transfer device, including a transfer hopper body for transferring broken glass falling from the drop plate bin; a telescopic dust-proof cover connected to the bottom of the drop plate bin for dust prevention when broken glass falls from the drop plate bin into the transfer hopper body; the telescopic dust-proof cover includes a dust-proof cover and a cylinder for driving the dust-proof cover to cover the transfer hopper body to prevent dust from rising when unloading broken glass; the telescopic dust-proof cover includes a hanging steel plate with one end connected to the output end of the cylinder and the other end connected to a flange.
[0010] The beneficial effects of the present invention are as follows:
[0011] 1. Reduce the loss of broken glass: During the transportation of broken glass by the belt conveyor, the belt will stick to materials, and at places with a height difference, broken glass will also leak out, resulting in waste of broken glass. By changing to the transportation of broken glass in the present invention, the transfer hopper is directly used to catch it at the cold-end drop plate bin and transported to the broken glass yard by forklift, avoiding waste of broken glass.
[0012] 2. Reduce the introduction of iron into the system: The full-mechanical conveying mode uses belt conveyors, hoppers, and chutes to transport broken glass. During the transportation process, the broken glass is in direct contact with the equipment, introducing a large amount of iron into the system and causing pollution to the broken glass. By changing to the transportation of broken glass in a closed transfer hopper, contact with various equipment is avoided.
[0013] 3. Reduce dust: During the transportation of broken glass in the full-mechanical conveying mode, the dust of broken glass is relatively large, especially at places with a large height difference, the dust of broken glass is extremely large. After changing to manual transfer, a closed transfer hopper is used, and the transfer hopper is directly used to catch it at the cold-end drop plate bin and transported to the broken glass yard by forklift. During the process, it is in a fully closed form, eliminating the phenomenon of dust. Brief Description of the Drawings

[0030] Reference Figures 1 to 8 As shown, the specific implementation manner of a new type of broken glass recycling and transfer device is described in detail, including a drop plate bin for temporarily storing broken glass. The drop plate bin mainly includes an emergency broken glass drop plate bin 7, a trimmed-edge broken glass drop plate bin 8, and a main drop plate broken glass drop plate bin 9. The bottom of the above drop plate bins is connected to a telescopic dust cover 6 to prevent dust from rising when broken glass falls from the drop plate bin into the transfer hopper body 2. When the transfer hopper body 2 is full of broken glass, a forklift transports the transfer hopper body 2 to the broken glass storage yard.
[0031] Specifically, the transfer hopper body 2 is of a cube structure. There is an observation window 1 at the top for observing whether the broken glass is full, which is located on both sides of the top; there is a base 3 at the bottom. The base 3 is provided with a bottom plate 32 through a rotating hinge 31 for discharging broken glass. There are forklift holes 33 on both sides of the base 3 to facilitate forklift transportation. There are two insertion tooth ears 24 welded at the top. Inside the insertion tooth ears 24, there is a broken glass inlet 25; after transporting to the broken glass storage yard, the forklift can complete self-unloading by pushing against the insertion tooth ears 24.
[0032] Reference Figure 1 、 Figures 5 - 8 As shown, in order to avoid dust rising when discharging broken glass, a telescopic dust cover 6 is provided on the broken glass inlet 35. The telescopic dust cover 6 includes a dust cover 61 and a cylinder 62 for driving the dust cover 61 to cover the transfer hopper body 2 to avoid dust rising when discharging broken glass.
[0033] In some specific embodiments, the telescopic dust cover 6 includes a hanging steel plate 63 with one end connected to the output end of the air cylinder 62 and the other end connected to a flange; the telescopic movement of the output end of the air cylinder 62 drives the hanging steel plate 63 and the dust cover 61 to expand and contract, and the dust cover 61 covers the broken glass inlet 35 to complete dust prevention.
[0034] In a further embodiment, the telescopic dust cover 6 further includes an upper flange 64, an upper tightening flange 65, a lower tightening flange 66 and a lower flange 67. The upper part of the dust cover 61 is fixed between the upper flange 64 and the upper tightening flange 65, and the lower part of the dust cover 61 is fixed between the lower tightening flange 66 and the lower flange 67.
[0035] In a further embodiment, the upper flange 64 is fixedly connected to the air cylinder 62, the top suspension plate of the hanging steel plate 63 is connected to the output end of the air cylinder 62, and the bottom suspension plate of the hanging steel plate 63 is fixedly connected to the lower flange 66. When the output end of the air cylinder 62 expands and contracts, it drives the hanging steel plate 63 and the dust cover 61 to expand and contract, so as to cover the broken glass inlet 35 to complete dust prevention.
[0036] In a further embodiment, there are at least two symmetric air cylinders 62, and the two air cylinders 62 extend and contract simultaneously, so as to complete dust prevention during the unloading of broken glass.
[0037] In a further embodiment, the dust cover 61 is a soft curtain, which is a soft, foldable or curlable curtain, used here to block dust. Its material is PVC with good ultraviolet resistance, strong light resistance, heat resistance, acid and alkali resistance, aging resistance and wear resistance, and is suitable for use in places that require dust prevention such as industrial production workshops.
[0038] Reference Figures 1 to 4 As shown, in some embodiments, the outer layer of the transfer hopper body 2 is made of a steel plate 21, and channel steel bars 22 are arranged outside the steel plate 21 to enhance the bearing capacity and stability of the shell formed by enclosing the steel plate 21.
[0039] Furthermore, the transfer hopper body 2 further includes a PE board 23 on the inner side of the steel plate 21 as a lining for protection, to prevent the broken glass from directly contacting the steel plate 21 inside the hopper, generating iron filings and causing pollution of the broken glass, which affects the quality of the glass.
[0040] The present utility model is respectively applied to the bottom ends of the emergency broken glass dropping plate bin 7, the edge cleaning broken glass dropping plate bin 8, and the main dropping plate broken glass dropping plate bin 9 for broken glass recovery. A telescopic dust cover 6 is arranged at the discharging opening of the dropping plate bin, which is controlled by an air cylinder 62 and can be directly covered above the transfer hopper to ensure dust removal and prevent material leakage.
[0041] An observation window 1 is provided at the edge of the transfer hopper. After the operator discovers that the transfer hopper is full through the observation window 1, the sector door inside the silo is opened to stop discharging. After the forklift driver forks away the full hopper and replaces it with an empty hopper, the sector door and the telescopic dust cover 6 can be opened again.
[0042] Forklift holes 33 are provided on both sides of the base 3 of the transfer hopper for convenient forklift transportation. Two inserting tooth ears 24 are welded on the top. After the transfer hopper is transported to the crushed glass yard, the forklift can complete self-unloading by pushing against the inserting tooth ears 24.
[0043] The traditional transfer hopper is not protected by a lining PE board 23. The crushed glass directly contacts the inner wall of the hopper, which is likely to generate iron filings and cause pollution to the crushed glass, affecting the glass quality.
[0044] During the actual use process, the situation of the crushed glass of the new transfer device compared with the traditional transfer device is as follows:
[0045] 1. Referring to Tables 1 and 9, the loss of crushed glass is reduced: The traditional transfer hopper was actually used from January to March 2024, and the loss rate of crushed glass was 0.35%. After replacing it with the new transfer hopper in April, the loss rate of crushed glass dropped to 0.15%, and the loss rate decreased by 0.20%.

[0047] Table 1
[0048] 2. Referring to Tables 2 and 10, the introduction of system iron is reduced: In the fully mechanical conveying mode, belt conveyors, hoppers, and chute pipes are used to convey crushed glass. During the conveying process, the crushed glass is in direct contact with the equipment, introducing a large amount of system iron and causing pollution to the crushed glass. Changing to a closed transfer hopper to transport the crushed glass can avoid contact with various equipment and reduce the introduction of system iron, approximately reducing by 20 ppm.
