Description

Technical Field

[0001] This utility model belongs to the field of glass annealing technology, and specifically relates to a hot air circulation device for glass annealing furnaces. Background Technology

[0002] Glass annealing furnaces are key thermal equipment in glass production lines. Their main purpose is to eliminate or reduce harmful residual stresses inside the glass caused by rapid and uneven cooling, thereby improving the glass's mechanical strength, thermal stability, optical uniformity, and processing performance.

[0003] In the prior art, a search of Chinese patent number CN211199014U discloses a ventilation circulation system for a glass annealing furnace; it includes an annealing furnace metal shell, electric heaters installed on both sides of the upper part of the annealing furnace metal shell, and a centrifugal fan installed at the middle position of the top of the annealing furnace metal shell. Roller drive devices are respectively installed on both sides of the annealing furnace metal shell, bearing seats are provided on the roller drive devices, and rollers are installed on the bearing seats. The upper end of the rollers is used to place glass ribbons; upper exhaust pipes are provided on both sides of the top of the annealing furnace metal shell, and the pipe openings of the upper exhaust pipes lead to the inner plate of the annealing furnace metal shell. At the same time, an under-plate exhaust pipe is provided at the bottom of the side end of the annealing furnace metal shell; the upper exhaust pipes and the under-plate exhaust pipes converge into the main exhaust pipe and are connected to the air inlet of the centrifugal fan through a flange.

[0004] When annealing glass products in a track kiln, the kiln body is generally divided into multiple independent temperature control zones. Each zone has its own independent air supply duct to ensure temperature control. However, the hot air cannot remove dust particles during circulation, which can easily scratch the glass products. When recovering the hot air in each zone, the above solution changes the air direction to expel dust particles, but it cannot recycle the residual heat of the hot air, thus reducing its practicality. Utility Model Content

[0005] When annealing glass products in a track kiln, the kiln body is typically divided into multiple independent temperature control zones, each with its own independent air supply duct. This ensures temperature control in each zone. However, the hot air cannot remove dust particles during circulation, which can easily scratch the glass products. Furthermore, when recovering hot air from each zone, the aforementioned solutions rely on changing the airflow direction to expel dust particles, failing to recycle residual heat and thus reducing practicality. This invention proposes a hot air circulation device for glass annealing kilns to overcome these technical problems in existing technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a hot air circulation device for a glass annealing furnace, comprising the annealing furnace body:

[0008] The annealing furnace body is equipped with a circulation component, a filtration component, a drive component, a cleaning component, a sealing component, and a collection component.

[0009] The circulation component is connected to the interior of the annealing furnace body so that the circulation component can circulate the hot air inside the annealing furnace body;

[0010] The filter assembly is internally connected to the circulation assembly so that the filter assembly filters the hot air circulating inside the circulation assembly;

[0011] The drive component has its output end fixedly installed at one end of the cleaning component, and the top end of the cleaning component is in contact with the bottom end of the filter component, so that the drive component drives the cleaning component to clean the surface of the filter component.

[0012] A sealing assembly, one side of which is attached to one side of the cleaning assembly, so that the cleaning assembly can drive the sealing assembly to move when it is in operation;

[0013] The collecting component has its collecting end located below the sealing component so that dust falls into the interior of the collecting component when the sealing component moves.

[0014] Furthermore, the circulation component includes a hot air blower, the bottom end of which is fixedly installed to the top end of the annealing furnace body, and a blower pipe is fixedly installed at the air outlet end of the hot air blower, the bottom end of which is fixedly installed to the top end of the annealing furnace body.

[0015] An air inlet pipe is fixedly installed at the air inlet end of the hot air blower, and one end of the air inlet pipe is fixedly installed to one side of the annealing kiln body.

[0016] Furthermore, the filter assembly includes a support frame, one side of which is fixedly installed to one side of the annealing furnace body, and a filter box is fixedly installed at the top of the support frame. The interior of the filter box is connected to the interior of the air inlet pipe, and a filter screen is fixedly installed inside the filter box.

[0017] Furthermore, the drive assembly includes a mounting bracket, one side of which is fixedly mounted to one side of the filter box, and the other side of which a motor is fixedly mounted.

[0018] Furthermore, the cleaning component includes a reciprocating screw, the outer surface of which is rotatably mounted to the inside of the filter box, one end of which is fixedly installed to the output end of the motor, a moving block is threadedly connected to the threaded surface of the reciprocating screw, a cleaning block is fixedly installed on the top of the moving block, the top of the cleaning block is in contact with the bottom of the filter screen, and a top block is fixedly connected to one side of the cleaning block.

[0019] Furthermore, the sealing assembly includes a limiting rod, both ends of which are fixedly connected to the inner wall of the filter box. A sealing block is slidably provided on the outer surface of the limiting rod. One side of the sealing block is in contact with one side of the top block. A spring is fixedly connected to one side of the sealing block, and one end of the spring is fixedly connected to the inner wall of the filter box.

[0020] Furthermore, the collection component includes a sliding groove, which is opened inside the filter box, and a collection box is slidably disposed inside the sliding groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model moves the cleaning component installed at the output end of the start-up drive component, so that the cleaning component cleans the filter surface of the filter component and pushes the dust that falls off. Since one side of the cleaning component is in contact with one side of the sealing component, when the cleaning component moves, it can push the sealing component to move, so that the cleaning component pushes the dust into the other side of the sealing component, so that the dust falls into the inside of the collection component for centralized collection. This ensures that while cleaning the dust, the hot air can be recycled, thereby improving the practicality of the hot air circulation device for glass annealing furnace.

[0023] 2. This utility model uses a starting motor to drive a reciprocating screw installed at the output end to rotate, causing the reciprocating screw to drive a moving block connected by a threaded surface to move back and forth. Since the outer surface of the moving block is slidably set with the inner wall of the filter box, and the top of the moving block is fixedly installed with the bottom of the cleaning block, when the moving block moves back and forth, it can drive the cleaning block to move back and forth, so that the cleaning block can clean the filter screen that is attached to the top. At the same time, when the cleaning block moves, it can drive the top block fixed on one side to move. Since there are multiple sets of top blocks arranged in a linear array, the dust falling from the surface of the filter screen can enter between the multiple sets of top blocks for centralized dust treatment.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0034] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0036] Please see Figures 1-6 As shown, this utility model is a hot air circulation device for a glass annealing furnace, including an annealing furnace body 1:

[0037] The annealing furnace body 1 is respectively equipped with a circulation component 2, a filter component 3, a drive component 4, a cleaning component 5, a sealing component 6, and a collection component 7;

[0038] The circulation component 2 is connected to the interior of the annealing furnace body 1 so that the circulation component 2 circulates the hot air inside the annealing furnace body 1.

[0039] The filter assembly 3 is internally connected to the interior of the circulation assembly 2, so that the filter assembly 3 filters the hot air circulating inside the circulation assembly 2;

[0040] The drive component 4 has its output end fixedly installed at one end of the cleaning component 5, and the top end of the cleaning component 5 is in contact with the bottom end of the filter component 3, so that the drive component 4 drives the cleaning component 5 to clean the surface of the filter component 3.

[0041] The sealing component 6 has one side that fits against one side of the cleaning component 5 so that the cleaning component 5 drives the sealing component 6 to move when it is in operation.

[0042] The collecting component 7 has its collecting end located on the underside of the sealing component 6 so that dust falls into the interior of the collecting component 7 when the sealing component 6 moves.

[0043] During use, the circulation component 2 is activated to circulate the hot air inside the annealing furnace body 1, thereby regulating the temperature inside the annealing furnace body 1. When the circulation component 2 is running, it allows the air to be filtered by the filter component 3 installed inside, thus trapping the filtered dust particles inside the filter component 3. Then, the drive component 4 is activated to drive the cleaning component 5 installed at the output end to move, so that the cleaning component 5 cleans the filter surface of the filter component 3 and pushes the dust that falls off. Since one side of the cleaning component 5 is in contact with one side of the sealing component 6, when the cleaning component 5 moves, it can push the sealing component 6 to move, so that the cleaning component 5 pushes the dust into the other side of the sealing component 6, so that the dust falls into the collection component 7 for centralized collection.

[0044] This invention moves the cleaning component 5 installed at the output end of the drive component 4 to clean the filter surface of the filter component 3 and push the dust that falls off. Since one side of the cleaning component 5 is in contact with one side of the sealing component 6, when the cleaning component 5 moves, it can push the sealing component 6 to move, so that the cleaning component 5 pushes the dust into the other side of the sealing component 6, so that the dust falls into the collection component 7 for centralized collection. This ensures that while cleaning the dust, the hot air can be recycled, thereby improving the practicality of the hot air circulation device for the glass annealing furnace.

[0045] In one embodiment, the circulation component 2 includes a hot air blower 201, the bottom end of which is fixedly installed with the top end of the annealing furnace body 1, and a blower pipe 202 is fixedly installed at the air outlet end of the hot air blower 201, the bottom end of which is fixedly installed with the top end of the annealing furnace body 1.

[0046] An air inlet pipe 203 is fixedly installed at the air inlet end of the hot air blower 201, and one end of the air inlet pipe 203 is fixedly installed to one side of the annealing kiln body 1.

[0047] By starting the hot air blower 201, the air inside the air inlet pipe 203 is extracted. Since the inside of the air inlet pipe 203 is connected to the inside of the annealing furnace body 1, the air inside the annealing furnace body 1 can be drawn into the hot air blower 201 and into the air blowing pipe 202. This allows the air to enter the inside of the annealing furnace body 1 through one end of the air blowing pipe 202, thus enabling the hot air inside the annealing furnace body 1 to circulate and improving the utilization efficiency of the hot air.

[0048] In one embodiment, the filter assembly 3 includes a support frame 301. One side of the support frame 301 is fixedly installed on one side of the annealing kiln body 1. A filter box 302 is fixedly installed on the top of the support frame 301. The interior of the filter box 302 is connected to the interior of the air inlet pipe 203. A filter screen 303 is fixedly installed inside the filter box 302.

[0049] Since the interior of the filter box 302 is connected to the interior of the air inlet pipe 203, the flowing air entering the air inlet pipe 203 can enter the interior of the filter box 302 and pass through the filter screen 303 installed inside the filter box 302, so that the filter screen 303 can filter the dust particles in the air, which is more convenient.

[0050] In one embodiment, the drive assembly 4 includes a mounting bracket 401, one side of which is fixedly mounted to one side of the filter box 302, and the other side of which a motor 402 is fixedly mounted.

[0051] The mounting bracket 401 is designed to support the motor 402 mounted on the other side, thereby improving the stability of the motor 402 during operation.

[0052] In one embodiment, the cleaning component 5 includes a reciprocating screw 501, the outer surface of which is rotatably connected to the interior of the filter box 302, one end of which is fixedly installed to the output end of the motor 402, a moving block 502 is threadedly connected to the threaded surface of the reciprocating screw 501, a cleaning block 503 is fixedly installed on the top end of the moving block 502, the top end of the cleaning block 503 is in contact with the bottom end of the filter screen 303, and a top block 504 is fixedly connected to one side of the cleaning block 503.

[0053] The reciprocating screw 501 installed at the output end of the motor 402 is driven to rotate, so that the reciprocating screw 501 drives the moving block 502, which is threadedly connected to the threaded surface, to move back and forth. Since the outer surface of the moving block 502 is slidably set with the inner wall of the filter box 302, and the top of the moving block 502 is fixedly installed with the bottom of the cleaning block 503, when the moving block 502 moves back and forth, it can drive the cleaning block 503 to move back and forth, so that the cleaning block 503 can clean the filter screen 303 that is attached to the top. At the same time, when the cleaning block 503 moves, it can drive the top block 504 fixed on one side to move. Since there are multiple sets of top blocks 504 arranged in a linear array, the dust falling from the surface of the filter screen 303 can enter between the multiple sets of top blocks 504 for centralized treatment of dust.

[0054] In one embodiment, the sealing assembly 6 includes a limiting rod 601, both ends of which are fixedly connected to the inner wall of the filter box 302. A sealing block 602 is slidably disposed on the outer surface of the limiting rod 601. One side of the sealing block 602 is in contact with one side of the top block 504. A spring 603 is fixedly connected to one side of the sealing block 602, and one end of the spring 603 is fixedly connected to the inner wall of the filter box 302.

[0055] Since one side of the sealing block 602 is in contact with one side of the top block 504, when the top block 504 moves with the movement of the cleaning block 503, the top block 504 can push the sealing block 602 to move. Since the interior of the sealing block 602 is slidably disposed with the outer surface of the limiting rod 601, and one side of the sealing block 602 is fixedly connected to one end of the spring 603, when the sealing block 602 moves, it can compress the spring 603 along the direction of the limiting rod 601. At the same time, the cleaning block 503 can push the dust into the other side of the sealing block 602 and make the dust fall downward.

[0056] In one embodiment, the collection component 7 includes a sliding groove 701, which is formed inside the filter box 302, and a collection box 702 is slidably disposed inside the sliding groove 701.

[0057] Since the collection box 702 is located on the lower side of the sealing block 602, when dust falls to the other side of the sealing block 602 as the cleaning block 503 pushes it, the dust can fall into the inside of the collection box 702 for centralized collection. By pulling the handle fixed on one side of the collection box 702, the collection box 702 can be moved out of the filter box 302 for centralized cleaning of dust.

[0058] Through the above technical solution, 1. The cleaning component 5 installed at the output end of the drive component 4 is moved by starting the drive component 4 so that the cleaning component 5 can clean the filter surface of the filter component 3 and push the dust that falls off. Since one side of the cleaning component 5 is in contact with one side of the sealing component 6, when the cleaning component 5 moves, it can push the sealing component 6 to move so that the cleaning component 5 can push the dust into the other side of the sealing component 6 so that the dust falls into the inside of the collection component 7 for centralized collection. This ensures that while cleaning the dust, the hot air can be recycled, thereby improving the practicality of the hot air circulation device for the glass annealing furnace.

[0059] 2. The reciprocating screw 501 installed at the output end is driven by the starting motor 402 to rotate, so that the reciprocating screw 501 drives the moving block 502 connected by the threaded surface to move back and forth. Since the outer surface of the moving block 502 is slidably set with the inner wall of the filter box 302, and the top of the moving block 502 is fixedly installed with the bottom of the cleaning block 503, when the moving block 502 moves back and forth, it can drive the cleaning block 503 to move back and forth, so that the cleaning block 503 can clean the filter screen 303 attached to the top. At the same time, when the cleaning block 503 moves, it can drive the top block 504 fixed on one side to move. Since there are multiple sets of top blocks 504 arranged in a linear array, the dust falling from the surface of the filter screen 303 can enter between the multiple sets of top blocks 504 for centralized treatment of dust.
