Description

Technical Field

[0001] The utility model relates to the field of glass preparation, and more specifically, to a glass kiln door. Background Art

[0002] Glass kiln is one of the indispensable equipment in the glass production process. Glass raw materials are added into the kiln through the open furnace door using conveyor belts and other devices.

[0003] The existing glass furnace door is usually hinged to one side of the charging port, and opened or closed by a cylinder or manually. However, this type of furnace door requires the conveyor belt to be close to charge. After the furnace door is opened, the high temperature emitted will burn the conveyor belt and other conveying devices, resulting in a reduction in the service life of the conveyor belt, and will cause heat loss inside the furnace, which is not conducive to the promotion of energy conservation and emission reduction.

[0004] Therefore, a new type of kiln door is needed to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that when the furnace door of the existing glass furnace is opened, the conveying mechanism such as the baking conveyor belt is easily caused to lose heat.

[0006] According to one aspect of the utility model, a glass kiln door is provided, including a kiln body, a feeding port is provided at one end of the kiln body, a furnace door is provided on the feeding port, the furnace door includes a door body and a hopper, the hopper is installed at the feeding port and covers the feeding port, the door body is located on one side of the hopper opening, and the door body is driven up and down by a driving mechanism to cover or open the feeding port.

[0007] Through this solution, if it is necessary to add materials, the door body will cover the feeding port, and the materials can be directly added to the hopper through the conveyor belt. Since the feeding port is blocked, the conveyor belt will not be burned by high temperature. When the required materials are added to the hopper and the conveyor belt is removed, the door body is pulled upward to expose the feeding port so that the materials can slide into the feeding port. Due to the obstruction of the materials, the heat loss in the furnace can be reduced.

[0008] Preferably, vertically arranged slide rails are provided on the kiln body at both sides of the feeding port, and the door body is slidably connected to the slide rails.

[0009] Through this solution, the door body is directly connected to the kiln body, which can improve the stability of the connection between the door body and the kiln body, ensure the sealing of the feeding port, and reduce heat loss.

[0010] Preferably, the side of the door body facing the feeding port is covered with heat insulation cotton.

[0011] Through this solution, the heat insulation cotton can not only improve the thermal insulation effect and reduce heat dissipation, but also can be close to the feeding port to improve the sealing effect of the door body.

[0012] Preferably, at least two polished rods are vertically arranged at the bottom of the hopper, the polished rods are slidably connected to the kiln body below the feeding port, and a weighing mechanism is arranged at the bottom end of the polished rods.

[0013] Through this solution, the weighing mechanism can weigh the material added to the hopper, so as to accurately know the amount of the added material and avoid the problem of deviation in the weight of the added material due to the small volume of the hopper.

[0014] Preferably, a measuring platform and a mounting portion are provided on the kiln body, the polished rod is slidably connected to the mounting portion, the weighing mechanism comprises a pressure sensor, the pressure sensor is provided on the measuring platform, and the bottom of the polished rod is in contact with the pressure sensor.

[0015] With this solution, the hopper can slide downward under the action of the weight of the material to transmit the pressure to the pressure sensor to measure the weight.

[0016] Preferably, the driving mechanism comprises a mounting frame and a driving cylinder, the driving frame is arranged on the top of the kiln body, and the driving cylinder is installed on the mounting frame and connected to the top of the door body.

[0017] Through this solution, the up and down movement of the driving cylinder drives the door body to open and close. The driving frame located at the top can prevent the material from contaminating the driving cylinder and can prevent the driving cylinder from directly contacting the high-temperature surface of the kiln body, thereby affecting its service life.

[0018] Preferably, a lower hook is provided on the top of the door body, an upper hook is connected to the piston rod of the driving cylinder, the upper hook is hooked and cooperated with the lower hook, and when the door body closes the feeding port, the lower part of the upper hook is located in the middle of the lower hook.

[0019] Through this solution, when the door body is at the bottom, the upper hook will not directly contact the lower hook, thereby avoiding affecting the weight detection accuracy.

[0020] One technical effect of the utility model is that, by adopting the glass kiln furnace door of the present application, a mode of adding materials first and then opening the door can be realized while ensuring the normal heat preservation effect, thereby avoiding the problem of equipment damage or reduced life caused by high temperature directly burning the conveyor belt during the door opening process, and can greatly reduce the loss of high temperature in the furnace.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] like Figures 1 to 4 As shown, the glass kiln door of the present application includes a kiln body 100, a feeding port 101 is provided at one end of the kiln body 100, a furnace door is provided on the feeding port 101, the furnace door includes a door body 120 and a hopper 110, the hopper 110 is installed at the feeding port 101 and covers the feeding port 101, the door body 120 is located on one side of the opening of the hopper 110, and the door body 120 is driven up and down by a driving mechanism to cover or open the feeding port 101.

[0033] Through the scheme of this embodiment, if it is necessary to add materials, the door body 120 will cover the feeding port 101, and the materials will be directly added to the hopper 110 through the conveyor belt. Since the feeding port 101 is blocked, the conveyor belt will not be burned by high temperature. When the required materials are added to the hopper 110 and the conveyor belt is removed, the door body 120 is pulled upward to expose the feeding port 101 so that the materials can slide into the feeding port 101. Due to the obstruction of the materials, the heat loss in the furnace can be reduced.

[0034] The door body 120 in this embodiment is made of one or more materials such as ceramic, fireproof brick or tungsten steel. For example, a ceramic plate or fireproof brick is fixed on the back of the tungsten steel plate, which not only facilitates the movement of the door body 120 and improves its stability and strength, but also has higher high temperature resistance.

[0035] In one embodiment of the present application, vertically arranged slide rails 102 are provided on the kiln body 100 on both sides of the charging port 101, and the door body 120 is slidably connected to the slide rails 102. The door body 120 is directly connected to the kiln body 100, which can improve the stability of its connection with the kiln body 100, ensure the sealing of the charging port 101, and reduce the loss of heat.

[0036] Since the kiln body 100 is made of fireproof bricks, it has a high thermal insulation effect. The temperature on the surface of the kiln body 100 is only tens of degrees Celsius. The traditional metal slide rail 102 can withstand the temperature in this range; and on both sides of the feeding port 101, damage caused by rising high temperature is avoided.

[0037] In one embodiment of the present application, the side of the door body 120 facing the feeding port 101 is covered with heat insulation cotton 121. The heat insulation cotton 121 can not only improve the heat preservation effect and reduce heat dissipation, but also can be close to the feeding port 101 to improve the sealing effect of the door body 120.

[0038] In one embodiment of the present application, at least two polished rods 111 are vertically arranged at the bottom of the hopper 110, and the polished rods 111 are slidably connected to the kiln body 100 below the feeding port 101, and a weighing mechanism is arranged at the bottom of the polished rods 111. The weighing mechanism can weigh the material added to the hopper 110, so as to accurately know the amount of the added material, and avoid the problem of deviation in the weight of the added material due to the small volume of the hopper 110.

[0039] In one embodiment of the present application, a measuring platform 104 and a mounting portion 103 are provided on the side of the kiln body 100, below the feeding port 101, a polished rod 111 is slidably connected to the mounting portion 103, and a weighing mechanism includes a pressure sensor 131, which is provided on the measuring platform 104, and the bottom of the polished rod 111 is in contact with the pressure sensor 131. The hopper 110 can slide downward under the weight of the material to transmit the pressure to the pressure sensor 131 to measure the weight.

[0040] In one embodiment of the present application, the driving mechanism includes a mounting frame 220 and a driving cylinder 210. The mounting frame 220 is disposed on the top of the kiln body 100. The driving cylinder 210 is mounted on the mounting frame 220 and connected to the top of the door body 120. The up and down movement of the driving cylinder 210 drives the door body 120 to open and close. The mounting frame 220 located at the top can prevent the material from contaminating the driving cylinder 210, and can prevent the driving cylinder 210 from directly contacting the high-temperature surface of the kiln body 100, which affects its service life.

[0041] In one embodiment of the present application, a lower hook 121 is provided on the top of the door body 120, and an upper hook 211 is connected to the piston rod of the driving cylinder 210. The upper hook 211 is hooked and matched with the lower hook 121. When the door body 120 closes the feeding port 101, the lower part of the upper hook 211 is located in the middle of the lower hook 121. When the door body 120 is at the bottom, the upper hook 211 will not directly contact the lower hook 121, so that the door body 120 naturally droops to close the feeding port 101, or is placed on the hopper 110, so as to prevent the driving cylinder 210 from squeezing the hopper 110 downward to affect the weight detection accuracy.

[0042] One technical effect of this embodiment is that by adopting the glass kiln furnace door of the present application, while ensuring the normal heat preservation effect, it is possible to implement a mode of adding materials first and then opening the door, thereby avoiding the problem of equipment damage or reduced life caused by high temperature directly burning the conveyor belt during the door opening process, and can greatly reduce the loss of high temperature in the furnace.

[0043] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
