Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, specifically relating to an electric melting furnace for melting high borosilicate glass. Background Technology

[0002] An electric melting furnace is an industrial furnace that uses electrical energy to convert into heat energy for glass melting. Electric melting furnaces emit no smoke and release pollutants such as SOx and NOx almost zero, making them particularly suitable for environmentally sensitive areas.

[0003] When using an electric melting furnace for glass production, the raw materials for glass processing need to be pre-melted. The pre-melted materials are then fed into subsequent processes. However, the temperatures of the pre-melted materials and the crucibles used for storing them are relatively high. To minimize heat loss and enhance temperature control, electric melting furnaces are typically closed by doors. However, the design of these doors, especially the commonly used sliding doors, still obstructs the view of the crucibles inside, even when the door is open, causing considerable inconvenience for manual handling. Therefore, this application proposes an electric melting furnace for melting high borosilicate glass. Utility Model Content

[0004] The purpose of this invention is to provide an electric melting furnace for melting high borosilicate glass, in order to solve the problem that most electric melting furnaces mentioned in the background art need to be closed through a door during use. The door design, especially the commonly used sliding door, still obstructs the view of the crucible inside even after the door is opened, causing many inconveniences for manual handling of the crucible.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric melting furnace for melting high borosilicate glass, comprising an electric melting furnace body, wherein the electric melting furnace body is provided with an opening and closing door with an opening and closing function and a storage frame for storing crucibles containing glass processing raw materials, and the opening and closing door is connected to the storage frame.

[0006] The electric melting furnace body is provided with a support plate, a support seat that rotates with the support plate, and a power mechanism for pushing the support plate up and down.

[0007] The support plate is provided with a rotating support frame, and the support frame is provided with a lifting unit, a lifting plate connected to the lifting unit, and a gripper unit installed on the lifting plate for clamping and releasing the crucible.

[0008] The support plate has at least two states, including a material-picking state and a retracted state. When the support plate is in the material-picking state, the stroke of the lifting unit covers the crucible located in the storage frame. When the support plate is in the retracted state, the gripper unit does not obstruct the movement of the opening and closing door.

[0009] Preferably, the electric melting furnace body is provided with slidingly fitted door opening and closing guide rods, and there are two door opening and closing guide rods, which are symmetrically distributed about the center line of the electric melting furnace body.

[0010] Preferably, a connecting plate is provided between the door opening and closing guide rod and the opening and closing door.

[0011] Preferably, one end of the connecting plate is sleeved with the door opening and closing guide rod, and the other end of the connecting plate is connected to the opening and closing door by a pin.

[0012] Preferably, a pressure plate is fitted onto the door opening and closing guide rod and abuts against the connecting plate. A fastening bolt is provided at the pressure plate and screwed into the door opening and closing guide rod and pressed against the pressure plate. The end of the pressure plate away from the fastening bolt is combined with the connecting plate by a pin.

[0013] Preferably, the power mechanism includes a power motor, which is mounted on the electric melting furnace body. The output shaft of the power motor is connected to the rotating shaft through a coupling. The rotating shaft is rotatably engaged with the support base. The rotating shaft is connected to the support plate through a flat key and a keyway.

[0014] Preferably, the power mechanism can also be a telescopic rod, with one end of the telescopic rod rotatably engaged with the middle of the support plate, and the other end of the telescopic rod rotatably engaged with the outer shell of the electric melting furnace body.

[0015] Preferably, an auxiliary frame is provided at the support frame, and vertically distributed guide grooves are provided in the auxiliary frame, with a slidingly fitted auxiliary rod inserted in the guide groove.

[0016] Preferably, the auxiliary rod is provided with an auxiliary plate that is plugged in, and the end of the auxiliary plate away from the auxiliary rod is rotatably engaged with the support plate.

[0017] Preferably, the electric melting furnace body is provided with a plurality of parallelly distributed support wheels and connecting seats that are rotatably mounted on the inner wall of the electric melting furnace body in cooperation with the support wheels.

[0018] Beneficial effects:

[0019] This utility model provides an electric melting furnace for melting high borosilicate glass. The power mechanism can drive the support plate to rotate around the support base, thereby causing the support plate to rise and fall. When the support plate rises, the lifting unit, gripper unit, and crucible on it rise in height without obstructing the normal opening and closing of the door. When the support plate falls, it can lower the height of the gripper unit and send the gripper unit to the position where the crucible is located, so that the gripper unit can clamp the crucible. Through the gripper unit and other components, the crucible can be moved from near the electric melting furnace body to an area where the line of sight is not obstructed, which facilitates the subsequent crucible transfer work.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1-4 As shown in the figure, this utility model provides an electric melting furnace for melting high borosilicate glass, including an electric melting furnace body 1. An electric melting furnace is an industrial furnace that converts electrical energy into heat energy to melt glass. A crucible containing raw materials for glass processing is sent into the electric melting furnace body 1 for pre-melting. The electric melting furnace body 1 is equipped with an opening and closing door 2 and a storage frame 3 for storing the crucible containing the glass processing raw materials. It should be noted that the opening and closing door 2 is connected to the storage frame 3. After the opening and closing door 2 is opened, the storage frame 3 can be pulled to remove the storage frame 3 from the electric melting furnace body 1. This solution is mainly used for the processing of high borosilicate glass, so the crucible contains the raw materials for high borosilicate glass processing.

[0028] To ensure smoother movement of the opening and closing door 2 and the storage frame 3, a sliding door opening and closing guide rod 4 is installed inside the electric melting furnace body 1. Two door opening and closing guide rods 4 are provided, and the two door opening and closing guide rods 4 are symmetrically distributed about the center line of the electric melting furnace body 1.

[0029] Specifically, a connecting plate 5 is provided between the door opening and closing guide rod 4 and the opening and closing door 2. One end of the connecting plate 5 is sleeved with the door opening and closing guide rod 4, and the other end of the connecting plate 5 is connected to the opening and closing door 2 by a pin. A pressure plate is sleeved on the door opening and closing guide rod 4 and abuts against the connecting plate 5. A fastening bolt 6 is provided at the pressure plate and is screwed into the door opening and closing guide rod 4 and pressed on the pressure plate. The end of the pressure plate away from the fastening bolt 6 is combined with the connecting plate 5 by a pin.

[0030] By setting two door opening and closing guide rods 4 connected to the opening and closing door 2 at the electric melting furnace body 1, the movement of the opening and closing door 2 is relatively smooth. This allows the crucible located in the storage frame 3 to be in the middle position of the electric melting furnace body 1, which facilitates the clamping operation of the gripper unit 11 on the crucible.

[0031] In order to remove the heated crucible from the electric melting furnace body 1, a support plate 7, a support seat 8 that is rotatably fitted with the support plate 7 and installed on the outer wall of the electric melting furnace body 1, and a power mechanism for pushing the support plate 7 to rise and fall around the support seat 8 are provided at the electric melting furnace body 1.

[0032] In one embodiment, the power mechanism includes a power motor, which is mounted on the electric melting furnace body 1. The electric melting furnace body 1 is made of a material with good heat insulation properties, so the internal heat will not be directly transferred to the power motor and will not hinder the operation of the power motor. The output shaft of the power motor is connected to the rotating shaft through a coupling. The rotating shaft is rotatably engaged with the support base 8. The rotating shaft is connected to the support plate 7 through a key and keyway transmission. In this way, the power motor can drive the support plate 7 to rotate around the support base 8, thereby driving the support plate 7 to rise and fall. When the support plate 7 rises, the lifting unit 9, the gripper unit 11, and the crucible on it rise in height, without obstructing the normal opening and closing of the opening and closing door 2. When the support plate 7 falls, it can reduce the height of the gripper unit 11 and send the gripper unit 11 to the position where the crucible is located, so that the gripper unit 11 can clamp the crucible.

[0033] In another embodiment, the power mechanism can also be a telescopic rod. One end of the telescopic rod is rotatably engaged with the middle of the support plate 7, and the other end of the telescopic rod is rotatably engaged with the outer shell of the electric melting furnace body 1. The telescopic rod can be an electric telescopic rod, which controls the lifting and lowering of the support plate 7. The connection point of the telescopic rod is located in the middle of the support plate 7. Compared with the power motor that drives the support plate 7 to rotate at the bottom, it is more labor-saving and puts less burden on the power components.

[0034] More specifically, a rotatable support frame is provided at the support plate 7, and a lifting unit 9, a lifting plate 10 connected to the lifting unit 9, and a gripper unit 11 installed at the lifting plate 10 for clamping and releasing the crucible are provided at the support frame. The lifting unit 9 can be an electric telescopic rod, and the gripper unit 11 can be an electric gripper.

[0035] Driven by the power mechanism, the support plate 7 has at least two states, including a material picking state and a retracted state. When the support plate 7 is in the material picking state, the stroke of the lifting unit 9 covers the crucible located in the storage frame 3. When the support plate 7 is in the retracted state, the gripper unit 11 does not obstruct the movement of the opening and closing door 2.

[0036] In order to adjust the angle of the lifting unit 9, an auxiliary frame 12 is provided at the support frame. A vertically distributed guide groove is provided in the auxiliary frame 12. An auxiliary rod 14 with sliding fit is inserted into the guide groove. An auxiliary plate 13 with plug fit is provided at the auxiliary rod 14. The end of the auxiliary plate 13 away from the auxiliary rod 14 is rotatably fitted with the support plate 7.

[0037] With the cooperation of components such as auxiliary plate 13 and auxiliary rod 14, the auxiliary plate 13 can adjust the direction of the support frame during the rotation of the support plate 7, so that the support frame and the lifting unit 9 on it remain vertical. In this way, the crucible will not shake significantly during the rotation of the support plate 7, thus preventing the material from spilling.

[0038] In order to reduce the friction force experienced by the storage frame 3 during movement, several parallel support wheels 15 and connecting seats 16 rotatably mounted on the inner wall of the electric melting furnace body 1 are provided inside the electric melting furnace body 1.

[0039] In summary, this utility model embodiment provides an electric melting furnace for melting high borosilicate glass. The power mechanism can drive the support plate 7 to rotate around the support base 8, thereby driving the support plate 7 to rise and fall. When the support plate 7 rises, the lifting unit 9, the gripper unit 11, and the crucible on it rise in height without obstructing the normal opening and closing of the opening and closing door 2. When the support plate 7 falls, it can reduce the height of the gripper unit 11 and send the gripper unit 11 to the position where the crucible is located, so that the gripper unit 11 can clamp the crucible.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
