Description

Technical Field

[0001] This invention relates to the field of glass production technology, and more specifically to a feeding device for a glass furnace. Background Technology

[0002] The glass production process generally includes processes such as raw material crushing, weighing, mixing, melting, forming and annealing. Feeding the prepared raw materials into the melting furnace is an important step. Since feeding the raw materials into the melting furnace is carried out in a high-temperature environment, it cannot be done manually. Currently, feeding machines are mostly used for feeding.

[0003] For example, patent application number CN202122052899.X discloses a feeding machine for a glass furnace, including a base, a hopper, a feeding trough, and a pushing mechanism. The hopper is supported by a bracket above the base. The feeding trough is inclinedly set at the discharge port at the bottom of the hopper and guided to the feeding port of the furnace. The pushing mechanism is installed on the base and includes an eccentric wheel mechanism, a transmission rod, a hinge chain, and a push plate. One end of the transmission rod is connected to the eccentric wheel mechanism, and the other end of the transmission rod is installed with the push plate. The hinge chain is installed between the middle of the transmission rod and the base. The hinge chain is a two-stage hinge structure. One end of the hinge chain is fixedly connected to the transmission rod, and the other end of the hinge chain is hinged to the base.

[0004] The aforementioned structure is located at the furnace opening. When replenishing raw materials to the hopper, it needs to be done near the furnace opening, which presents the following problems: the furnace opening space is limited, making it difficult for personnel and equipment to work; the furnace opening is hot, creating a harsh operating environment; and there is an operational risk, as personnel may be burned upon contact with the furnace opening. Summary of the Invention

[0005] To address the aforementioned issues, this patent designs the feeding structure and pusher as detachable components. The hopper and feeding trough of the feeding structure can move independently, allowing for feeding away from the kiln. This design offers advantages such as good safety, ease of operation, and proximity to heat sources. Furthermore, a sealing slide plate is installed on the pusher, which not only partially seals the furnace opening during operation but also when the pusher is separated from the feeding structure. This reduces the possibility of molten slurry flowing out and minimizes heat loss. The solution is as follows:

[0006] This invention provides a feeding device for a glass furnace, including a furnace door 1 and a feeding structure. The furnace door 1 is located at the furnace opening of a furnace 2.

Detailed Implementation

[0022] The invention will be further described below through specific embodiments, but it should be noted that these embodiments are merely illustrative and do not limit the scope of the invention.

[0023] See Figure 1-4 This invention provides a feeding device for a glass furnace. The device includes a furnace door 1, a feeding structure, a pushing structure 12, a slide rail 8 arranged in a front-to-back direction, a feed frame 9 protruding forward from the furnace door 1, two enclosed sliding plates 10 arranged side-by-side on the front side of the feed frame 9, and two pulleys 11 arranged side-by-side vertically on the enclosed sliding plates 10 (one pulley 11 is slidably connected to the upper or lower side of the push rod 6 when the push rod 6 moves). The furnace door 1 is located on the furnace opening of the furnace 2, sealing the opening. The bottom of the frame 3 is slidably mounted on the slide rail 8, with its rear side pressing against the furnace door 1. Its rear side is detachably connected to the furnace door 1 (via a crossbeam 21 and an upper fixing structure 22). A pushing structure 12 is provided between its front side and the ground or the slide rail 8 to push the frame 3 backward.

[0024] The feeding structure includes a frame 3, a hopper 4 on top of the frame 3, a feeding trough 5 at the bottom of the hopper 4 arranged diagonally downwards from front to back, and two pushing mechanisms at the bottom of the frame 3 capable of pushing material forward and backward. The pushing mechanisms include push rods 6 arranged forward and backward, push plates 7 at the rear end of the push rods 6, and a drive assembly on the frame 3 that drives the push rods 6. The feeding frame 9 is arranged forward and backward, with its rear end connected to the kiln 2 and its front end open. The feeding trough 5 and push rods 6 both pass backward through the feeding frame 9. The push plate 7 is perpendicular to the push rods 6 and is located above the rear end of the feeding trough 5, continuously pushing the raw material in the feeding trough 5 backward. Two closed sliding plates 10 are respectively located on the left and right sides of the front end of the feeding frame 9, adjacent to the outer sides of the left and right sides of the feeding trough 5, vertically arranged, and capable of sliding up and down. The two pushing mechanisms are arranged side-by-side, with the push rods 6 passing through the two closed sliding plates 10. The push rod 6 is detachably mounted on the feeding mechanism (specifically, the drive assembly) and is located between two pulleys 11 on the corresponding side. When the push rod 6 moves back and forth and up and down, it pushes the closed slide plate 10 to move up and down. When the closed slide plate 10 moves up and down and when the push rod 6 is separated from the feeding mechanism (the closed slide plate 10 and its structure are in a low position due to gravity), it always closes the left and right sides of the feed frame 9.

[0025] Specifically, see Figure 1-3 In this embodiment of the invention, both the furnace door 1 and the feeding frame 9 are provided with heat insulation layers. The furnace door 1 is rectangular (vertically arranged), and the feeding frame 9 is a rectangular frame (vertically arranged). The sealing slide plate 10 is a rectangular plate with a vertically arranged strip hole in its middle for the push rod 6 to pass through and move up and down. A set of guide units is provided on each of the left and right sides of the front end of the feeding frame 9. The guide unit includes two vertical plates arranged side by side (arranged in the front-back direction, with a sliding groove in the rear of its inner side in the vertical direction). The sealing slide plate 10 is located between the two vertical plates on the corresponding sides, and its left and right sides are slidably mounted on the sliding grooves of the two vertical plates. Two side plates are provided on its front side and on the left and right sides of the strip hole (arranged in the front-back direction). The two side plates are arranged side by side, and two pulleys 11 are located between the two side plates and on the upper and lower sides of the strip hole, respectively. The pulleys 11 are arranged in the left-right direction and are rotatably mounted on the two side plates. When the push rod 6 is in the high position and the low position, the upper and lower ends of the sealing slide plate 10 extend upward and downward relative to the corresponding ends of the feed frame 9 to ensure that the left and right sides of the feed frame 9 are always closed.

[0026] Among them, see Figure 1 In this embodiment of the invention, the rear of the feeding trough 5 extends into the feeding frame 9, and the left and right sides of its middle section are suspended on the frame 3. Two vibration springs (in total) are vertically arranged between the lower front side of the trough 5 and the left and right sides of the frame 3, and a vibration motor is located at the front of the trough 5. Two pushing mechanisms are located on the left and right sides of the feeding trough 5.

[0027] Further, see Figure 1 In this embodiment of the invention, the furnace door 1 is detachably mounted on the furnace opening, and a lower fixing structure 13 is provided between it and the kiln 2. A receiving groove 14 is provided directly below the furnace door 1 and the feeding frame 9 to receive the flowing molten slurry. The receiving groove 14 is arranged in the left-right direction. There are two lower fixing structures 13, which are located on the left and right sides of the feeding frame 9, respectively. The lower fixing structure 13 includes a tensioner arranged in the front-back direction, a straight screw rod arranged in the front-back direction on the furnace door 1 and located next to the feeding frame 9, and an L-shaped screw rod arranged vertically on the receiving groove 14. The upper part of the L-shaped screw rod (the lower part is arranged vertically and fixed to the front side of the receiving groove 14) is bent backward to form a straight section (flush with the straight screw rod). The tensioner is detachably mounted between the front end of the straight screw rod and the rear end of the straight section.

[0028] Among them, see Figure 1-2The driving assembly in this embodiment of the invention includes a drive motor 19, a support groove 15 arranged in the front-rear direction, a rear rotating arm 16 (vertically arranged) hinged to the lower rear end of the support groove 15 (via a left-right rotating shaft), a front fixed arm 17 (perpendicular to the support groove 15) fixedly connected to the lower front end of the support groove 15, and a drive arm 18 hinged to the lower end of the front fixed arm 17 (via a left-right rotating shaft). The front part of the push rod 6 is detachably disposed in the support groove 15 (via multiple U-shaped locking members arranged in a front-rear parallel manner). The lower end of the rear rotating arm 16 is hinged (via a left-right rotating shaft) at the rear of the frame 3. The drive motor 19 is arranged in the left-right direction at the front of the frame 3 and its drive shaft is fixedly connected to the lower end of the drive arm 18. The two pushing mechanisms move backward simultaneously or at different times.

[0029] Preferably, see Figure 1 In this embodiment of the invention, two drive motors 19 are arranged side by side. The drive motors 19 are mounted on a slide block, which is slidably mounted on the frame 3. An adjustment handwheel 20 (with a handwheel at the front end) is provided between the slide block and the front side of the frame 3. The adjustment handwheel 20 is arranged in the front-back direction and is used to adjust the drive motors 19 back and forth. The range of motion and swing amplitude of the push plate 7 can be controlled by adjusting the adjustment handwheel 20.

[0030] Further, see Figure 1 In this embodiment of the invention, two crossbeams 21 are provided at the rear of the frame 3 and above the feeding frame 9. The two crossbeams 21 are located on the left and right sides of the top of the feeding frame 3, respectively. The crossbeams 21 are arranged in the front-to-back direction, with their rear ends resting against the furnace door 1 and positioned at the top of the feeding frame 9. An upper fixing structure 22 is provided between the crossbeams 21 and the furnace door 1. The upper fixing structure 22 includes a fixing block on the furnace door 1 and above the feeding frame 9 (located above the crossbeams 21) and a vertically arranged locking screw on the fixing block (with a handwheel at its upper end). The locking screw passes downward through the corresponding side of the crossbeam 21 and its lower end is threadedly connected to the top of the feeding frame 9. Removing the locking screw allows the furnace door and the feeding structure to be separated.

[0031] Further, see Figure 1 and 4In this embodiment of the invention, the slide rail 8 consists of two rails arranged side by side (in the front-to-back direction). The bottom of the frame 3 has four rectangularly arranged track wheels 23 that cooperate with the two rails. The track wheels 23 slide on their respective rails. The two rear track wheels 23 are driven by corresponding travel motors at the rear of the frame 3. Both the travel motor and the drive motor 19 are located at the bottom of the frame 3. The travel motor is located behind the drive motor 19 and is protected by a protective cover to prevent damage from falling molten slurry. A limiting mechanism 24 (specifically a vertically arranged stop bar, located on the left and right sides of the frame 3 and directly opposite the stop block) is provided adjacent to the rear of the kiln 2 or the ground (preferably). The limiting mechanism 24 blocks and limits the frame 3 to prevent damage to the furnace door 1. The push-top structure 12 includes a rotating rod arranged in the left-right direction and located between two tracks, a top rod arranged in the middle of the rear side of the rotating rod and in the front-back direction, and a top plate arranged in the left-right direction at the rear end of the top rod. The top rod is arranged diagonally downward from back to front, and the two ends of the rotating rod are respectively rotatably mounted on the inner side walls of the two tracks. The top plate presses against the front side of the frame 3. Rotating the rotating rod upward can release the pressing effect on the frame 3; during the movement of the frame 3, rotating the rotating rod upward by about 360° to below the slide rail 8 allows the frame 3 to pass smoothly.

[0032] Furthermore, in this embodiment of the invention, the push rod 6 is a rectangular water-cooled plate, and its two cooling water inlets and outlets (one inlet and one outlet) are connected to the cooling water circulation system via hoses. Since the push rod 6 is detachable, the interface of the cooling water circulation system can be located near the furnace opening, which can reduce the length of the hoses.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
