Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to an environmentally friendly glass waste melting and regeneration device. Background Art

[0002] In modern society, glass is a widely used material, applied in daily life and various industrial fields. From windows and beverage bottles to automotive glass and electronic products, glass is everywhere. With the end of the life of products and the rapid change of consumption patterns, a large amount of glass waste is generated. If these waste glass are properly handled, they can be re-entered into the production process to achieve resource recycling.

[0003] The main component of glass is silica sand, which is formed by high-temperature melting and has the characteristics of being recyclable. Recycling glass waste can not only reduce the demand for mining of raw materials, but also significantly reduce the burden on the environment. During the recycling process, glass waste usually needs to be cleaned and sorted, and then sent to the melting equipment for reprocessing. Through melting, the waste glass becomes liquid again and can be made into new glass products. This process plays an important role in resource conservation and environmental protection.

[0004] However, existing glass melting equipment has some technical defects in terms of energy efficiency. During the melting process, the equipment usually consumes a lot of energy to maintain a high-temperature operating environment. At the same time, the high-temperature exhaust gas generated is often not effectively utilized and is directly discharged to the outside, resulting in a large amount of heat energy loss. This not only increases energy consumption, but also aggravates environmental pressure. In view of this, we propose an environmentally friendly glass waste melting and regeneration device.

A plurality of air outlet pipes 32 are arranged equidistantly from front to back at the top and near the right side of the preheating box 3. The high-temperature flue gas in the air duct 2 enters the plurality of air inlet pipes 30 respectively, and then is introduced into the preheating chamber 34 from the air inlet pipes 30. The flue gas after heat exchange is discharged from the air outlet pipe 32. The air outlet pipe 32 is externally connected to a flue gas purification device. The flue gas purification device is a prior art and will not be described in detail here to avoid direct discharge and environmental pollution.

[0031] Each preheating chamber 34 is provided with a feed assembly 4, which includes a heat exchange feed pipe 40 and a motor 45. The heat exchange feed pipe 40 is located in the preheating chamber 34, and the left and right ends of the heat exchange feed pipe 40 are respectively fixedly connected to the left and right sides of the inner wall of the preheating chamber 34. The function of the preheating chamber 34 is to use the hot air discharged from the glass melting furnace body 1 to preheat the waste glass to be processed, so as to reduce the energy demand and environmental impact of the glass melting furnace body 1, thereby achieving environmental protection. The motor 45 is located on the left side of the preheating box 3, and the heat exchange feed pipe 40 rotates. An auger 44 is connected, and the output shaft of the motor 45 passes through the left side of the preheating box 3 and is coaxially connected to the left end of the rotating shaft of the auger 44. The motor 45 is connected to an external power source to work, and the auger 44 is driven by the motor 45 to rotate, so that the auger 44 pushes the glass waste in the heat exchange feeding pipe 40 to the left or right. During preheating, the auger 44 pushes the glass waste to the left to turn the glass waste, which is beneficial to preheating. When the glass waste in the heat exchange feeding pipe 40 is discharged, the auger 44 pushes the glass waste to the right, so that the preheated glass waste is discharged from the guide pipe 42;

[0032] A feeding pipe 41 is provided at the top of the heat exchange feeding pipe 40 and near the left end. The top end of the feeding pipe 41 passes through the top of the inner wall of the preheating box 3 to the outside.

[0034] Specifically, the multiple air inlet pipes 30 are respectively connected to the multiple preheating chambers 34, and the multiple air outlet pipes 32 are respectively connected to the multiple preheating chambers 34, so that the high-temperature flue gas can enter the multiple preheating chambers 34 as needed, so that the multiple feeding components 4 are preheated respectively, and the preheated glass waste can be introduced into the glass melting furnace body 1, thereby realizing continuous glass waste melting operation and improving processing efficiency.

[0035] Furthermore, a first control valve 31 is provided on the air intake pipe 30 to facilitate the staff to control the opening and closing of the multiple air intake pipes 30 .

[0036] Furthermore, the bottom of the heat exchange feeding pipe 40 is a semicircular structure, and the auger 44 is located at the bottom of the heat exchange feeding pipe 40. The outer wall of the auger 44 fits with the inner wall of the heat exchange feeding pipe 40, ensuring that when the auger 44 pushes the waste glass to the left, the waste glass can be flipped upward. Similarly, when the auger 44 pushes the preheated waste glass to the right, all the preheated waste glass in the heat exchange feeding pipe 40 can be output.

[0037] Furthermore, the outer wall of the heat exchange feeding pipe 40 is provided with a plurality of heat conducting fins 46 to increase the contact area between the outer wall of the heat exchange feeding pipe 40 and the high temperature flue gas, thereby improving the heat exchange effect and thus improving the preheating efficiency of the waste glass in the heat exchange feeding pipe 40 .

[0038] Furthermore, a second control valve 43 is provided on the material guiding pipe 42 to facilitate the staff to control the opening and closing of the plurality of material guiding pipes 42 .

[0039] When the environmentally friendly glass waste melting and regeneration device of this embodiment is in use, the staff starts the motor 45, and then puts the glass waste from the feeding pipe 41 into the heat exchange feeding pipe 40. The motor 45 drives the auger 44 to rotate in the opposite direction, so that the auger 44 pushes the glass waste in the heat exchange feeding pipe 40 to the left, so that the glass waste is turned over, which is beneficial to preheating. The exhaust pipe 10 discharges the smoke generated by the glass melting furnace body 1 melting the glass waste into the air guide pipe 2. The high-temperature smoke in the air guide pipe 2 enters into the multiple air inlet pipes 30 respectively, and then is introduced into the preheating chamber 34 from the air inlet pipe 30. The multiple heat-conducting fins 46 on the outer wall of the heat exchange feeding pipe 40 increase the outer wall of the heat exchange feeding pipe 40 and the high temperature flue gas. The contact area of ​​the hot flue gas is increased to improve the heat exchange effect, thereby improving the preheating efficiency of the waste glass in the heat exchange feeding pipe 40. When the waste glass is fully preheated, the motor 45 drives the auger 44 to rotate forward. At this time, the corresponding second control valve 43 is opened, and the auger 44 pushes the waste glass to the right, so that the preheated waste glass is output from the guide pipe 42, and the preheated waste glass is introduced into the melting chamber of the glass melting furnace body 1 through the guide pipe 42. Since the waste glass has a certain amount of heat after being preheated, the preheated waste glass can be quickly melted, which reduces the demand for additional energy, improves energy utilization efficiency, achieves the purpose of energy saving, and thus realizes the role of environmental protection.
