Description

Technical Field

[0001] This utility model belongs to the field of glass melting technology, and specifically relates to a glass melting device. Background Technology

[0002] In the manufacturing process of glass insulators, glass melting is required. The glass insulators are produced using the molten glass. During the production process, the quality of the molten glass directly determines the final quality of the glass insulators. The presence of air bubbles in the molten glass can easily affect the pass rate of the glass insulators. In existing equipment, the raw materials are introduced into the melting furnace, and the molten glass is stirred horizontally to make the air bubbles float to the surface, thereby reducing the number of air bubbles in the molten glass. However, unmelted powder slag or refractory materials mixed in with the molten glass can affect the quality of the glass insulators as the molten glass flows. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a glass melting apparatus to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this glass melting apparatus to solve its technical problem is as follows: A glass melting apparatus is provided, including a melting furnace. A stirring cylinder is located in the center of the melting furnace, an inner cylinder is located outside the stirring cylinder, an intermediate cylinder is placed outside the inner cylinder, and an outer cylinder is placed outside the intermediate cylinder. The bottoms of the inner and outer cylinders are fixedly connected to the bottom of the melting furnace. The bottoms of both the stirring cylinder and the intermediate cylinder are suspended inside the melting furnace. The stirring cylinder is fixedly supported on the inner cylinder by a bracket, and the intermediate cylinder is fixedly supported on the outer cylinder by a bracket. A feed cylinder is provided on the melting furnace, and its outlet is connected to the top of the stirring cylinder. A motor is fixedly installed on the top of the melting furnace, and the motor's output end passes through a rotating shaft fixedly installed on the top of the melting furnace. The rotating shaft extends into the stirring cylinder and a stirring rod is fixedly installed thereon. A discharge valve is fixedly installed on the bottom of the melting furnace.

[0005] Furthermore, several slag discharge valves are evenly provided below the intermediate cylinder and fixedly installed at the bottom of the melting furnace.

[0006] Furthermore, a collection hopper is fixedly installed at the bottom of the furnace, and a discharge valve is fixedly installed at the bottom of the collection hopper.

[0007] Furthermore, electric heating tubes are evenly arranged inside the stirring cylinder, inner cylinder, intermediate cylinder, and outer cylinder.

[0008] Furthermore, there are two discharge valves, which are installed on both sides of the melting furnace.

[0009] Furthermore, an exhaust pipe is provided at the top of the furnace, and an activated carbon filter plate is installed inside the exhaust pipe.

[0010] Furthermore, the bottom of the furnace is fixedly equipped with support legs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a glass melting apparatus. In use, raw materials are fed into a stirring drum through a feeding cylinder. Starting the motor drives the rotating shaft and stirring rod to rotate, stirring the molten glass. During the flow, the molten glass flows from the stirring drum into the inner drum, passes over the top of the inner drum into the intermediate drum, then passes over the bottom of the intermediate drum into the outer drum, and finally passes over the top of the outer drum into the outside of the outer drum. It is then discharged through a discharge valve. During this process, as the molten glass passes over the tops of the inner and outer drums, it adheres tightly to these tops, allowing air bubbles to rise more effectively. Furthermore, as the cross-section of each drum gradually increases, the flow rate of the molten glass gradually slows down, thus facilitating the expulsion of air bubbles. This apparatus allows for the convenient elimination of air bubbles in the molten glass.

[0012] 2. The glass melting device of this utility model can conveniently discharge unmelted powder slag or refractory materials deposited below the intermediate cylinder through a slag discharge valve.

[0013] 3. A glass melting device according to this utility model example can collect and discharge waste material discharged from the slag discharge valve through a collection hopper.

[0014] 4. A glass melting device according to this utility model can heat the molten glass by means of an electric heating tube, thus avoiding the cooling of the molten glass.

[0015] 5. A glass melting device according to this utility model can alternately discharge material through two discharge valves, so that the molten glass in the melting furnace is always in a flowing state.

[0016] 6. A glass melting apparatus according to this utility model can filter and discharge waste gas through an exhaust pipe and an activated carbon filter plate.

[0017] 7. A glass melting device according to this utility model example can conveniently support the melting furnace through support legs. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1: like Figure 1 As shown, this embodiment provides a glass melting device, including a melting furnace 1. A stirring cylinder 2 is located in the middle of the interior of the melting furnace 1. An inner cylinder 3 is located outside the stirring cylinder 2. An intermediate cylinder 4 is fitted over the inner cylinder 3, and an outer cylinder 5 is fitted over the intermediate cylinder 4. The bottoms of the inner cylinder 3 and the outer cylinder 5 are fixedly connected to the bottom of the melting furnace 1. The bottoms of both the stirring cylinder 2 and the intermediate cylinder 4 are suspended inside the melting furnace 1. The stirring cylinder 2 is fixedly supported on the inner cylinder 3 by a bracket, and the intermediate cylinder 4 is fixedly supported on the outer cylinder 5 by a bracket. A feed cylinder 6 is provided on the melting furnace 1. The outlet of the feed cylinder 6 is connected to the top of the stirring cylinder 2. A motor 7 is fixedly installed on the top of the melting furnace 1. The output end of the motor 7 passes through the top of the melting furnace 1 and a rotating shaft 8 is fixedly installed. The rotating shaft 8 extends into the stirring cylinder 2 and a stirring rod 9 is fixedly installed. A discharge valve 10 is fixedly installed at the bottom of the melting furnace 1.

[0023] In this embodiment, several slag discharge valves 11 are uniformly arranged below the intermediate cylinder 4 and fixedly installed at the bottom of the furnace 1.

[0024] In this embodiment, a collection hopper 12 is fixedly installed at the bottom of the furnace 1, and a discharge valve 13 is fixedly installed at the bottom of the collection hopper 12.

[0025] In this embodiment, electric heating tubes 14 are uniformly arranged inside the stirring cylinder 2, inner cylinder 3, intermediate cylinder 4 and outer cylinder 5 respectively.

[0026] In this embodiment, there are two discharge valves 10, which are installed on both sides of the furnace 1.

[0027] In this embodiment, an exhaust pipe 15 is provided on the top of the furnace 1, and an activated carbon filter plate 16 is provided inside the exhaust pipe 15.

[0028] In this embodiment, the bottom of the melting furnace 1 is fixedly installed with support legs 17.

[0029] In use, the raw material is fed into the mixing drum 2 through the feed cylinder 6. The motor 7 is started, which drives the rotating shaft 8 and the stirring rod 9 to rotate, stirring the molten glass. During the flow, the molten glass flows from the mixing drum 2 into the inner drum 3, passes over the top of the inner drum 3 and enters the intermediate drum 4, then passes over the bottom of the intermediate drum 4 and enters the outer drum 5, until it passes over the top of the outer drum 5 and enters the outside of the outer drum 5. Finally, it is discharged through the discharge valve 10. During this process, as the molten glass passes over the tops of the inner drum 3 and the outer drum 5, it adheres tightly to these tops, causing air bubbles within the molten glass to... The device allows for better upward movement of the molten glass. As the cross-section of each cylinder gradually increases and the flow rate of the molten glass gradually slows down during its outward movement, it can better expel air bubbles. When the molten glass passes the bottom of the intermediate cylinder 4, the flow rate of the molten glass slows down, which facilitates the deposition of unmelted powder slag or refractory materials in the molten glass below the intermediate cylinder 4. By periodically opening the slag discharge valve 11, the slag discharge effect can be achieved. This device can easily eliminate air bubbles in the molten glass and can also precipitate and discharge waste residue in the molten glass during the melting process, making the molten glass purer.
