Description

Technical Field

[0001] The utility model belongs to the technical field of glass furnaces, and particularly relates to a waste heat recovery device for a glass furnace. Background Art

[0002] A glass melting furnace is a thermal equipment used for melting glass batch in glass manufacturing. When producing glass through a glass melting furnace, the proportion of energy consumption cost generally accounts for 40% to 45% of the total production cost, and more than about 30% of the heat energy is discharged in the form of waste gas. In order to reduce production costs, a waste heat recovery device is needed to reuse the discharged waste heat.

[0003] The Chinese Patent Network CN211373278U discloses a waste heat recovery device for a glass furnace, which relates to the field of glass furnaces and includes a housing. A motor box and a purification box are fixedly installed on the top of the housing. A suction fan is arranged in the motor box. The suction fan includes a motor and a fan blade. An installation hole three is arranged on one side of the housing. A filter screen is fixedly installed on the inner side wall of the installation hole three. A wind deflector one is fixedly installed on the inner side wall of the air inlet pipe. A dust collection box is fixedly installed at the bottom of the air inlet pipe. A spring is fixedly installed on the inner side wall of the bottom of the dust collection box. A receiving plate is fixedly installed at the top of the spring. An electrode plate one is fixedly installed at the bottom of the receiving plate. An electrode plate two is fixedly installed on the inner side wall of the bottom of the receiving plate.

[0004] In the prior art, when taking out the preheated raw materials from the inside of the preheating box, the preheating box needs to be slid out from the inside of the housing. Since it takes a certain amount of time to take and place the raw materials on the preheating plate, in order not to affect the working efficiency of the recovery device, multiple preheating boxes can be set. At this time, the preheating box that has completed the raw material preheating can be completely moved out from the inside of the housing, and then the preheating box with un-preheated raw materials can be moved into the inside of the housing, so that the working efficiency of the preheating box will not be affected. In the prior art, due to the stacking of raw materials on the preheating plate, the overall weight of the preheating box is relatively heavy, so it is relatively laborious to completely move the preheating box out from the inside of the housing.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0015] The utility model has the following beneficial effects:

[0016] 1. When the raw materials on the placement component are preheated, directly pull up the handle, and the handle squeezes the first spring through the connecting plate. At the same time, the connecting plate drives the fixed block to move out of the fixed groove on the top of the outer shell. Then, pull the L-shaped plate through the handle, and the L-shaped plate drives the placement component to move out of the inner part of the outer shell. At the same time, the L-shaped plate drives the universal wheels to slide on the ground through the support plate and the support column. At this time, the operator can push the placement component with the unpreheated raw materials through the corresponding L-shaped plate and directly move it into the inner part of the outer shell for preheating. In summary, when taking and placing the raw materials, it can be carried out outside the outer shell. This setting makes the overall working efficiency of the device not affected, and it is relatively labor-saving and convenient to move the placement component out of the inner part of the outer shell.

[0017] 2. Start the motor, so that the motor can rotate the screw rod, and the screw rod can drive the L-shaped baffle to move downward. The L-shaped baffle can drive the scraper to move downward through the connecting column. Since the scraper is in contact with one side of the filter screen, the moving scraper can scrape the dust adhering to the filter screen, so that the filter screen will not be blocked due to dust accumulation, and the whole operation process is automatically completed, thus improving the overall practicality of the device.

[0018] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationships are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.

[0030] Please refer to Figures 1-6As shown in the figure, the utility model relates to a waste heat recovery device for a glass furnace, which includes a housing 1. A chute 2 is opened at the bottom of the inner wall of the housing 1. A support column 3 is movably connected inside the chute 2. A universal wheel 4 is arranged at the bottom end of the support column 3. The top end of the support column 3 is fixedly connected with a support plate 5. A placing component 6 is fixedly connected to the top of the support plate 5. An L-shaped plate 7 is fixedly connected to one side of the support plate 5. A fixing component 8 is arranged at the top of the L-shaped plate 7.

[0031] After the raw materials on the placing component 6 are preheated, the fixing component 8 is driven to release the fixation of the L-shaped plate 7, and then the L-shaped plate 7 is directly pulled, so that the L-shaped plate 7 drives the support plate 5 to move at the bottom of the inner wall of the housing 1. The support plate 5 drives the support column 3 to move inside the chute 2. At this time, the universal wheel 4 arranged at the bottom end of the support column 3 can roll on the ground, so that the whole placing component 6 can be moved out of the housing 1, and then the raw materials can be taken and placed outside the housing 1.

[0032] The support plate 5 can block the chute 2, so that when the waste heat exhaust gas flows into the housing 1, it will not flow out from the chute 2. When the raw materials on the placing component 6 are pulled by the L-shaped plate 7, with the assistance of the support column 3 and the universal wheel 4, the whole pulling process is relatively labor-saving. At the same time, the fixing component 8 can fix the L-shaped plate 7 in contact with the housing 1, so that the L-shaped plate 7 will not drive the placing component 6 to move out of the housing 1 due to the universal wheel 4 during the preheating of the raw materials.

[0033] In one embodiment, for the above-mentioned placing component 6, the placing component 6 includes a bracket 601. A placing groove 602 is opened on the inner wall of the bracket 601. A placing plate 603 is movably connected inside the placing groove 602. A pulling groove 604 is opened on the top of the placing plate 603.

[0034] When moving the placing component 6 out of the housing 1, the raw materials inside the topmost placing plate 603 can be taken. After the raw materials are taken, the topmost placing plate 603 is pulled through the pulling groove 604 on it, and the placing plate 603 is moved out of the bracket 601, and then the raw materials on the second layer are taken, and so on until the bottom layer. When placing the raw materials, the above operations can be carried out in reverse.

[0035] The setting of the bracket 601 makes both sides of the placing plate 603 unobstructed, so that the waste heat exhaust gas has a better effect when heating the raw materials on the placing plate 603. At the same time, the placing plate 603 can be moved out of the bracket through the placing groove 602, and this setting makes it unobstructed when taking and placing the raw materials on the lower placing plate 603.

[0036] In one embodiment, for the above-mentioned fixing component 8, the fixing component 8 includes a fixing block 801. A fixing groove 802 is formed at the top of the outer shell 1, and the fixing groove 802 penetrates through the L-shaped plate 7. The fixing block 801 is movably connected to the fixing groove 802. A connecting plate 803 is movably connected to the top of the L-shaped plate 7. The connecting plate 803 is fixedly connected to the fixing block 801. A T-shaped column 804 is fixedly connected to the top of the L-shaped plate 7. The T-shaped column 804 is movably connected to the connecting plate 803. A first spring 805 is arranged on the outer side of the T-shaped column 804. A handle 806 is fixedly connected to the top of the connecting plate 803.

[0037] When moving the placing component 6 out of the interior of the outer shell 1, directly pull the handle 806 upward, so that the connecting plate 803 can move upward and compress the first spring 805. At this time, the connecting plate 803 can drive the fixing block 801 to move out of the interior of the fixing groove 802 on the outer shell 1, and then directly pull the L-shaped plate 7 through the handle 806, and make the L-shaped plate 7 drive the placing component 6 to move out of the interior of the outer shell 1.

[0038] When the L-shaped plate 7 comes into contact with the front surface of the outer shell 1, the first spring 805 can push the connecting plate 803 downward and make the connecting plate 803 drive the fixing block 801 to directly move into the fixing groove 802 on the outer shell 1 and fix the L-shaped plate 7. When releasing the fixation of the L-shaped plate 7, directly pull the fixing block 801 through the handle 806. In summary, the operations of fixing and releasing the fixation of the L-shaped plate 7 are relatively convenient.

[0039] In one embodiment, for the above-mentioned outer shell 1, a through groove 9 is formed on one side of the outer shell 1, and the through groove 9 penetrates through the outer shell 1. An air inlet pipe 10 is fixedly connected to the interior of the through groove 9 on one side of the outer shell 1. A filter screen 11 is fixedly installed on the inner wall of the air inlet pipe 10. A collection groove 12 is formed on the inner wall of the air inlet pipe 10. A connecting frame 13 is fixedly connected to the bottom of the air inlet pipe 10. A support frame 14 is fixedly connected to the bottom of the connecting frame 13. A collection box 15 is movably connected to the interior of the support frame 14.

[0040] When the air inlet pipe 10 conveys the waste heat to the interior of the outer shell 1, the filter screen 11 can filter the dust carried by the passing waste heat. The filtered dust can directly fall into the interior of the collection box 15 through the collection groove 12 and the connecting frame 13. When cleaning the dust collected inside the collection box 15, directly move the collection box 15 out of the interior of the support frame 14.

[0041] The setting of the filter screen 11 enables the waste heat and exhaust gas not to pollute the raw materials when preheating the raw materials inside the outer shell 1 with the waste heat and exhaust gas carried.

[0042] In one embodiment, for the above-mentioned filter screen 11, a scraper 16 is provided on one side of the filter screen 11. The scraper 16 is inclined. One side of the scraper 16 is fixedly connected to a connecting column 17. One end of the connecting column 17 is fixedly connected to an L-shaped baffle 18. The L-shaped baffle 18 is movably connected to the air inlet pipe 10. The top of the air inlet pipe 10 is fixedly connected to a mounting frame 19. A screw rod 20 is rotatably connected inside the mounting frame 19. The L-shaped baffle 18 is threadedly connected to the screw rod 20. A motor 21 is fixedly installed on the top of the mounting frame 19. The top end of the screw rod 20 penetrates through the mounting frame 19 and is fixedly connected to the output end of the motor 21.

[0043] The motor 21 is started once every once in a while. The motor 21 in the working state drives the screw rod 20 to rotate. The rotating screw rod 20 drives the L-shaped baffle 18 to move downward. The L-shaped baffle 18 drives the scraper 16 to move downward through the connecting column 17. When the scraper 16 moves downward, it can scrape off the dust adhering to the filter screen 11 and make the dust directly fall off from the filter screen 11.

[0044] The setting of the scraper 16 enables the dust adhering to the filter screen 11 to be automatically cleaned once every once in a while, so that too much dust will not accumulate on the filter screen 11, and thus the flow rate inside the air inlet pipe 10 will not be affected.

[0045] In one embodiment, for the above-mentioned connecting frame 13, a mounting block 22 is fixedly connected to the inner wall of the connecting frame 13. A limiting cylinder 23 is fixedly connected to the top of the mounting block 22. A limiting disk 24 is movably connected inside the limiting cylinder 23. A limiting column 25 is fixedly connected to the top of the limiting disk 24. The top end of the limiting column 25 is fixedly connected to an inclined baffle 26. A second spring 27 is arranged at the bottom of the limiting disk 24. A blocking plate 28 is fixedly connected to the bottom of the air inlet pipe 10. One side of the inclined baffle 26 is movably connected to the blocking plate 28.

[0046] The dust filtered by the filter screen 11 can directly fall onto the inclined baffle 26. At the same time, the dust scraped by the scraper 16 also directly falls onto the top of the inclined baffle 26. When cleaning the filter screen 11, as the scraper 16 and the L-shaped baffle 18 continuously move downward, when the L-shaped baffle 18 moves into the interior of the collection tank 12 and contacts the inner wall of the collection tank 12, the L-shaped baffle 18 can continue to move downward and squeeze the inclined baffle 26 downward. At this time, the inclined baffle 26 squeezes the second spring 27 through the limit post 25 and the limit disk 24, causing a gap to form between the inclined baffle 26 and the blocking plate 28. At this time, the dust on the inclined baffle 26 can directly roll downward under the guidance of the inclined baffle 26 and fall directly into the collection box 15 through the connecting frame 13. When the L-shaped baffle 18 moves upward, the second spring 27 can push the limit disk 24 upward and cause the limit disk 24 to push the inclined baffle 26 upward through the limit post 25. When the L-shaped baffle 18 moves out of the interior of the collection tank 12, the inclined baffle 26 can automatically reset with the assistance of the second spring 27.

[0047] When the L-shaped baffle 18 moves into the interior of the collection tank 12, it can temporarily block the air inlet pipe 10. At this time, the continuously moving L-shaped baffle 18 can push the inclined baffle 26 downward, causing the dust on the inclined baffle 26 to directly fall into the collection box 15. At this time, due to the blocking of the L-shaped baffle 18, the waste heat exhaust gas will not blow the dust collected inside the collection box 15 when the dust falls into the collection box 15, and when the placement assembly 6 is moved out of the interior of the housing 1, the air inlet pipe 10 can also be blocked by the L-shaped baffle 18.

[0048] In one embodiment, for the above-mentioned housing 1, a suction fan 29 is fixedly installed inside the through slot 9 on the other side of the housing 1. One side of the suction fan 29 is fixedly connected to a transport pipe 30. The top of the housing 1 is fixedly installed with a purification box 31. The transport pipe 30 is fixedly connected to one side of the purification box 31. The other side of the purification box 31 is fixedly connected to an air outlet pipe 32.

[0049] The suction fan 29 can extract the waste heat exhaust gas inside the housing 1. The extracted waste heat exhaust gas flows into the interior of the purification box 31 through the transport pipe 30. At the same time, the purification box 31 can purify the toxic substances contained in the waste heat exhaust gas inside. The purified waste heat exhaust gas can then flow to the outside of the device through the air outlet pipe 32.

[0050] Through the above technical solutions: 1. After the raw materials on the placing component 6 are preheated, directly pull the handle 806 upward, causing the handle 806 to squeeze the first spring 805 through the connecting plate 803. At the same time, the connecting plate 803 drives the fixed block 801 to move out of the fixing groove 802 at the top of the housing 1. Then, pull the L-shaped plate 7 through the handle 806, and make the L-shaped plate 7 drive the placing component 6 to move out of the interior of the housing 1. At the same time, the L-shaped plate 7 drives the universal wheels 4 to slide on the ground through the support plate 5 and the support columns 3. At this time, the operator can push the placing component 6 with unpreheated raw materials through the corresponding L-shaped plate 7 and directly move it into the interior of the housing 1 for preheating. In summary, when taking and placing the raw materials, it can be carried out outside the housing 1. This setting ensures that the overall working efficiency of the device is not affected, and it is relatively labor-saving and convenient to move the placing component 6 out of the interior of the housing 1; 2. Start the motor 21, so that the motor 21 can rotate the screw 20, and the screw 20 can drive the L-shaped baffle 18 to move downward. The L-shaped baffle 18 can drive the scraper 16 to move downward through the connecting column 17. Since the scraper 16 is in contact with one side of the filter screen 11, the moving scraper 16 can scrape off the dust adhering to the filter screen 11, so that the filter screen 11 will not be blocked due to dust accumulation, and the entire operation process is automatically completed, thereby improving the overall practicality of the device.
