Description

Technical Field

[0001] This utility model belongs to the technical field of glass production equipment. Specifically, this utility model relates to a furnace overflow baffle device. Background Technology

[0002] In the glass manufacturing industry, especially in the production of high-precision glass such as photovoltaic glass and optical glass, the cleanliness of the furnace overflow (particularly the overflow at the junction of the rolling mill and the annealing furnace) directly determines the quality grade of the finished glass. After the molten glass flows out of the furnace overflow, it needs to undergo rolling, annealing and other processes to form glass sheets. The surface of the incompletely solidified glass sheets and the interior of the molten glass are extremely sensitive to impurities. Willow catkins floating around the workshop in spring, mosquitoes breeding in summer, and dust and debris generated from routine equipment maintenance and floor cleaning can easily enter the production area through the overflow.

[0003] Chinese Patent (Publication No.: 217077379U) discloses a glass furnace overflow structure applied in the field of glass furnace technology. The overflow body (1) of the glass furnace overflow structure is made of steel. A glass pulling channel (2) is provided at the upper part of the overflow body (1). A cavity (3) is provided on the overflow body (1) below the glass pulling channel (2). Multiple heating air guns (4) are also installed on the overflow body (1), and the nozzles of the heating air guns (4) extend into the cavity (3). However, at the overflow of this glass furnace, contaminants can easily contaminate the glass, affecting the quality of glass production. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a kiln overflow baffle device that can prevent willow catkins, mosquitoes, dust, and debris from contaminating the glass through the kiln overflow. To achieve the above objective, the technical solution adopted by this utility model is as follows: a kiln overflow baffle device, including a roof support, which is installed at the kiln overflow, and a baffle structure and a baffle cleaning structure are provided on the roof support.

[0005] The curtain structure includes a curtain and a lifting roller. The two ends of the lifting roller are respectively set at both ends of the ceiling support. A lifting reducer is set on the ceiling support. The output shaft of the lifting reducer is connected to the lifting roller. One end of the curtain is connected to the lifting roller.

[0006] The curtain cleaning structure includes a roller brush, with both ends of the roller brush respectively set at both ends of the ceiling support. A cleaning reducer is set on the ceiling support, and the output shaft of the cleaning reducer is connected to the roller brush. The roller brush contacts the curtain.

[0007] The ceiling support is connected to a dust collection trough, with the dust collection trough located at both ends of the ceiling support and attached to the curtain.

[0008] The ash collection trough is equipped with a first magnetic plate at both ends, and the first magnetic plate is attracted to the ceiling support.

[0009] The end of the curtain is provided with a second magnetic plate, which is attracted to the ceiling support.

[0010] The ash collection trough has a square-shaped structure.

[0011] The canopy support is provided with a first bearing and a second bearing. The lifting roller is connected to the canopy support through the first bearing, and the roller brush is connected to the canopy support through the second bearing.

[0012] The technical effect of this utility model is as follows: When the operator starts the lifting reducer on the ceiling support, the output shaft of the lifting reducer drives the lifting roller to rotate. The curtain, which was originally wrapped around the surface of the lifting roller, is gradually lowered under the combined action of the curtain's own weight and the rotation of the lifting roller. After the curtain is lowered into place, it is straightened and then the second magnetic plate is tightly attracted to the ceiling support, eliminating the gap between the curtain and the support.

[0013] Simultaneously, as the curtain retracts, the cleaning reducer starts, driving the roller brush to rotate. The roller brush rotates in the opposite direction to the curtain's movement, creating reverse friction to enhance the cleaning effect. At this time, the brush bristles are in close contact with the curtain surface, gradually sweeping away debris during rotation, ensuring the curtain remains clean and continues to provide protection. The debris swept off by the roller brush falls directly into the dust collection trough located directly below the roller brush under gravity. Attached Figure Description

[0016] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0017] like Figure 1 As shown, a kiln overflow baffle device includes a roof support 1, which is installed at the kiln overflow. A baffle structure 2 and a baffle cleaning structure 3 are mounted on the roof support 1. The roof support 1 forms the basic frame of the entire baffle device. During glass production, the baffle structure 2 prevents insects, catkins, and dust from contaminating the overflow of the calender, thus preventing them from entering the equipment or contacting the glass sheets and affecting production and product quality. The baffle cleaning structure 3 sweeps away dust, debris, catkins, and other impurities adhering to the baffle structure 2, ensuring its cleanliness.

[0018] The curtain structure 2 includes a curtain 201 and a lifting roller 202. The two ends of the lifting roller 202 are respectively set at the two ends of the ceiling support 1. A lifting reducer 203 is set on the ceiling support 1. The output shaft of the lifting reducer 203 is connected to the lifting roller 202. One end of the curtain 201 is connected to the lifting roller 202.

[0019] The outer layer of the curtain 201 is a high-temperature resistant alloy plate, the middle layer is a ceramic fiber heat insulation layer, and the inner layer is equipped with a mosquito-proof mesh layer. The mosquito-proof mesh layer is made of high-temperature resistant stainless steel wire mesh with a mesh diameter of ≤0.5mm, which can block mosquitoes and small debris. The wire mesh has good air permeability to prevent the overflow outlet temperature from being too high, which would cause overheating and sticking to the rollers. The curtain 201 completely covers one end of the canopy support 1 to the other end. During the glass production process, the curtain 201 can prevent external debris from entering the kiln overflow outlet, blocking spring willow catkins, summer mosquitoes, and dust generated from daily cleaning, etc., and prevent debris from entering the kiln or contacting the glass plate that is not fully cured, which would cause bumps, indentations or internal impurities on the glass surface, affecting the glass quality.

[0020] One end of the curtain 201 is fixedly connected to the lifting roller 202. The lifting roller 202 rotates to drive the curtain 201 to roll up and lower, thereby controlling the curtain's obstruction and opening of the kiln overflow outlet. The lifting reducer 203 provides stable and controllable rotational power to the lifting roller 202. When the curtain 201 needs to be closed to block debris during glass production, the operator starts the lifting reducer 203, which rotates forward. The lifting reducer 203 transmits power to the lifting roller 202, causing it to rotate synchronously. As the lifting roller 202 rotates, the curtain 201, originally wrapped around its surface, is gradually lowered to the designated position under its own weight.

[0021] When the curtain needs to be opened, the operator starts the lifting reducer 203 to reverse, which drives the lifting roller 202 to rotate. Under the rotational traction force of the lifting roller 202, the curtain 201 is gradually wrapped around the surface of the lifting roller 202, thus realizing the winding of the curtain.

[0022] The curtain cleaning structure 3 includes a roller brush 301, with its two ends respectively mounted on the two ends of the ceiling support 1. A cleaning reducer 302 is mounted on the ceiling support 1, and the output shaft of the cleaning reducer 302 is connected to the roller brush 301. The roller brush 301 contacts the curtain 201. By rotating the roller brush 301, debris attached to the surface of the curtain 201, as well as dust and debris accumulated during production, and external pollutants such as willow catkins and mosquitoes, can be removed. The length of the roller brush 301 is slightly greater than the width of the curtain 201. When the curtain 201 is rolled up, the cleaning reducer 302 starts synchronously, driving the roller brush 301 to rotate. The rotation direction of the roller brush 301 is opposite to the movement direction of the curtain 201, forming reverse friction to enhance the cleaning effect. At this time, the bristles of the roller brush 301 are in close contact with the surface of the curtain 201, gradually sweeping away debris from the surface of the curtain 201 during rotation, ensuring that the curtain 201 remains clean and continues to play a protective role. A dust collection trough 4 is connected to the ceiling support 1. The two ends of the dust collection trough 4 are respectively set at both ends of the ceiling support 1, and the dust collection trough 4 is in contact with the curtain 201. The surface of the dust collection trough 4 is in contact with the curtain 201, and the two ends of the dust collection trough 4 are connected to the ceiling support 1. The curtain 201 is sandwiched between the dust collection trough 4 and the ceiling support 1. When the curtain 201 moves up and down, the cleaning reducer 302 drives the roller brush 301 to rotate and sweep the debris on the surface of the curtain 201. The dust collection trough 4 is directly below the roller brush 301 and is in contact with the curtain 201. The debris swept off the surface of the curtain 201 falls directly into the dust collection trough 4 below under the action of gravity, avoiding most of the debris from scattering.

[0023] The dust collection trough 4 is equipped with first magnetic plates 5 at both ends, which are attracted to the ceiling support 1. The dust collection trough 4 is connected to the ceiling support 1 through the first magnetic plates 5. The first magnetic plates 5 are attached to the ceiling support 1, and at the same time, they hold the dust collection trough 4 in place. When it is necessary to clean the dust collection trough 4, it can be removed from the first magnetic plates 5 for easy cleaning. After cleaning, the two ends of the dust collection trough 4 are reattached to the first magnetic plates 5.

[0024] A second magnetic plate 6 is provided at the end of the curtain 201, and the second magnetic plate 6 is attracted to the ceiling support 1. The end of the curtain 201 is connected to the second magnetic plate 6, and the second magnetic plate 6 is attracted to the ceiling support 1, so that the curtain 201 and the ceiling support 1 can fit together, eliminating the gap between the curtain 201 and the ceiling support 1. This can effectively block mosquitoes, willow catkins, dust and other debris from entering the kiln overflow outlet through the gap between the curtain and the support. At the same time, the second magnetic plate 6 can also reduce the impact of a breeze on the curtain 201 and reduce the swaying of the curtain 201.

[0025] The dust collection trough 4 has a U-shaped structure. The U-shaped structure of the dust collection trough 4 can maximize the coverage of the area where debris falls, forming a comprehensive storage boundary. At the same time, the U-shaped structure can reduce the shaking of the curtain 201 when the dust collection trough 4 is in contact with the curtain 201.

[0026] The ceiling support 1 is equipped with a first bearing 7 and a second bearing 8. The lifting roller 202 is connected to the ceiling support 1 via the first bearing 7, and the roller brush 301 is connected to the ceiling support 1 via the second bearing 8. The connection of the lifting roller 202 to the ceiling support 1 via the first bearing 7 reduces the rotational friction resistance of the lifting roller 202 and reduces power loss. The connection of the roller brush 301 to the ceiling support 1 via the second bearing 8 also reduces the rotational friction resistance of the lifting roller 202.

[0027] The operator starts the lifting reducer 203 on the ceiling support 1. The output shaft of the lifting reducer 203 drives the lifting roller 202 to rotate. The curtain 201, which was originally wrapped around the surface of the lifting roller 202, is gradually lowered under the combined action of its own weight and the rotation of the lifting roller 202. After the curtain 201 is lowered into place, it is straightened and then the second magnetic plate 6 is tightly attracted to the ceiling support 1, eliminating the gap between the curtain and the support. The curtain 201 can block external debris from entering the kiln overflow outlet and contaminating the glass.

[0028] Simultaneously, as the curtain 201 retracts, the cleaning reducer 302 starts synchronously, driving the roller brush 301 to rotate. The rotation direction of the roller brush 301 is opposite to the movement direction of the curtain 201, creating reverse friction to enhance the cleaning effect. At this time, the bristles of the roller brush 301 are in close contact with the surface of the curtain 201, gradually sweeping away debris from the surface of the curtain 201 during rotation, ensuring that the curtain 201 remains clean and continues to provide protection. The debris swept away by the roller brush 301 falls directly into the dust collection trough 4 located directly below the roller brush under the action of gravity.
