Description

Technical Field

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

[0002] The glass kiln is one of the indispensable equipment in the glass production process. During the high-temperature melting process of the kiln, raw materials such as glass scraps or sand are added into the kiln through the open furnace door using devices such as conveyor belts.

[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 feed materials. 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 other feeding mechanisms; if the material is fed away from the charging port, it may cause the problem of inaccurate addition of raw materials and waste.

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

[0005] One purpose of the utility model is to solve the problem that the existing kiln charging device is easily subjected to high temperature due to the opening of the furnace door, resulting in a reduction in service life.

[0006] According to one aspect of the utility model, there is provided a glass kiln feeding system, 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 is a feeding wheel, and the feeding wheel is rotatably connected to the feeding port; it also includes a conveyor belt and a driving mechanism, the conveyor belt is used to convey materials to the feeding wheel, and the driving mechanism is used to drive the feeding wheel to rotate so that the material falls into the feeding port.

[0007] Through this solution, the feeding wheel can seal the feeding port to prevent heat from overflowing and burning the conveyor belt; if feeding is required, it is only necessary to put the feeding wheel into each hopper through the conveyor belt, and the rotation of the feeding wheel can bring the material into the feeding port and fall into the kiln; due to the obstruction of the feeding wheel and the material in the hopper, the feeding port will not be completely open, so there will be no waste of heat and the burning of the conveyor belt will be reduced.

[0008] Preferably, the feeding wheel comprises a plurality of adjacent fixed hoppers, the hoppers surround a core shaft and have their bottoms fixed to the core shaft, the core shaft is rotatably connected to the kiln body so that the hoppers can rotate into or out of the feeding port, and the width of the hoppers matches the feeding port.

[0009] Through this solution, the volume of each hopper is consistent, and the feeding wheel can pour the materials in different hoppers into the kiln in sequence by rotating to complete the feeding, and then rotate to the outer hopper to feed.

[0010] Preferably, the inner layer of the hopper and spaces between the hoppers are filled and covered with a fireproof layer.

[0011] Through this solution, the hopper is made of high temperature resistant metal materials such as tungsten steel, has a certain rigidity, and the fireproof layer on the surface protects the hopper and increases its service life.

[0012] Preferably, fixing parts are protruded from the kiln body on both sides of the feeding port, and both ends of the core shaft are rotatably connected to the fixing parts.

[0013] Through this solution, both ends of the exposed core shaft are connected to the fixing part, which can avoid the problem of reducing the service life of the core shaft due to the hot air leaking from the gap of the feeding port.

[0014] Preferably, the driving mechanism comprises a driving wheel and a driving motor, wherein the driving motor drives the driving wheel to rotate, and the driving wheel is located outside the kiln body and can drive the feeding wheel to rotate.

[0015] Through this solution, the driving wheel outside the kiln is used to drive the charging wheel, so that the driving mechanism can be kept away from the kiln, avoiding high temperature baking and increasing the service life.

[0016] Preferably, the driving wheel is rotatably connected to the driving frame, and a plurality of paddles are provided on the driving wheel, and the paddles can extend into the hopper to drive the feeding wheel to rotate.

[0017] Through this solution, only the paddle and the driving wheel are used to pry the hopper, and there is no need to directly install it on the kiln body, thereby reducing the influence of heat transfer on the driving wheel and the driving motor.

[0018] Preferably, the height of the driving frame is smaller than the height of the feeding port, and the driving motor is fixed to the driving frame.

[0019] Through this solution, the driving motor is kept as far away from the kiln body as possible, which facilitates heat dissipation and increases its service life.

[0020] Preferably, a baffle plate is provided above the feeding port, and the baffle plate is located on the top of the kiln body.

[0021] Through this solution, the baffle plate can block the materials thrown out by the conveyor belt into the hopper of the feeding wheel, so as to prevent the materials from being thrown onto the top of the kiln body due to excessive speed.

[0022] One technical effect of the utility model is that, by adopting the glass kiln feeding system, the opening size of the feeding port can be reduced as much as possible while ensuring normal feeding, thereby avoiding overflow of heat, protecting the conveyor belt and increasing its service life; and it can reduce heat loss, which helps to save energy and reduce emissions.

[0030] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] like Figures 1 to 5 As shown, a glass kiln feeding system in an embodiment of the present application includes a kiln body 100, a feeding port 110 is provided at one end of the kiln body 100, a furnace door is provided on the feeding port 110, the furnace door is a feeding wheel 200, and the feeding wheel 200 is rotatably connected to the feeding port 110; it also includes a conveyor belt 400 and a driving mechanism, the conveyor belt 400 is used to convey materials to the feeding wheel 200, and the driving mechanism is used to drive the feeding wheel 200 to rotate so that the material falls into the feeding port 110.

[0036] Through the scheme of this embodiment, the feeding wheel 200 can seal the feeding port 110 to prevent heat from overflowing and burning the conveyor belt 400; if feeding is required, it is only necessary to put the feeding wheel 200 into each hopper 210 through the conveyor belt 400, and the rotation of the feeding wheel 200 can bring the material into the feeding port 110 and fall into the inside of the kiln; due to the obstruction of the feeding wheel 200 and the material in the hopper 210, the feeding port 110 will not be completely open, so as to avoid heat waste and reduce the burning of the conveyor belt 400.

[0037] In one embodiment of the present application, the feeding wheel 200 includes a plurality of adjacent fixed hoppers 210, the hoppers 210 surround the mandrel and the bottom is fixed to the mandrel, the mandrel is rotatably connected to the kiln body 100 so that the hoppers 210 can be rotated to enter or move out of the feeding port 110, and the width of the hoppers 210 matches the feeding port 110. The volume of each hopper 210 is the same, and the feeding wheel 200 can pour the materials in different hoppers 210 into the kiln in turn by rotating to complete the feeding, and rotate to the outer hopper 210 to feed.

[0038] The hopper 210 is made of metal and is fixed to the core shaft by welding or other means to form a wheel shape. Gaps are left between the hoppers 210 and filled with refractory materials such as ceramic mud to reduce heat exchange between the hoppers 210 and avoid the hopper 210 located inside the kiln transferring heat to the hopper 210 located outside, causing heat loss and waste.

[0039] In one embodiment of the present application, the inner layer of the hopper 210 and the space between the hoppers 210 are filled and covered with a fireproof layer 230. The hopper 210 is made of a high temperature resistant metal material such as tungsten steel and has a certain rigidity. The fireproof layer 230 on the surface protects the hopper 210 and increases its service life. The hopper 210 is a bucket-shaped structure with only a top opening, and the volume of each hopper 210 is the same.

[0040] In one embodiment of the present application, a fixing portion 111 is protruded from the kiln body 100 on both sides of the charging port 110, and both ends of the mandrel are rotatably connected to the fixing portion 111. The two ends of the exposed mandrel are connected to the fixing portion 111, which can prevent the hot air leaking from the gap of the charging port 110 from reducing the life of the mandrel.

[0041] In one embodiment of the present application, the driving mechanism includes a driving wheel 310 and a driving motor 320. The driving motor 320 drives the driving wheel 310 to rotate. The driving wheel 310 is located outside the kiln body 100 and can rotate the charging wheel 200. By using the driving wheel 310 outside the kiln to drive the charging wheel 200, the driving mechanism can be kept away from the kiln to avoid high temperature and increase the service life.

[0042] In one embodiment of the present application, the driving wheel 310 is rotatably connected to the driving frame 330, and a plurality of paddles 311 are provided on the driving wheel 310, and the paddles 311 can extend into the hopper 210 to rotate the feeding wheel 200. The hopper 210 is only driven by the paddles 311 and the driving wheel 310, and does not need to be directly installed on the kiln body 100, thereby reducing the influence of heat transfer on the driving wheel 310 and the driving motor 320.

[0043] The length of the paddle 311 enables it to contact the hopper 210 without being fully inserted into the hopper 210, thereby increasing the lever arm to facilitate its rotation.

[0044] In one embodiment of the present application, the height of the driving frame 330 is less than the height of the charging port 110, and the driving motor 320 is fixed to the driving frame 330. The driving motor 320 is as far away from the kiln body 100 as possible to facilitate heat dissipation and increase its service life.

[0045] In one embodiment of the present application, a baffle plate 120 is provided above the feeding port 110, and the baffle plate 120 is located at the top of the kiln body 100. The baffle plate 120 can block the material thrown out by the conveyor belt 400 into the hopper 210 of the feeding wheel 200, so as to prevent the material from being thrown to the top of the kiln body 100 due to excessive speed.

[0046] One technical effect of this embodiment is that by adopting the glass kiln feeding system, the opening size of the feeding port can be reduced as much as possible while ensuring normal feeding, thereby avoiding overflow of heat, protecting the conveyor belt and increasing its service life; and it can reduce heat loss, which helps to save energy and reduce emissions.
