Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic kiln technology, specifically to an automatic air supply system for ceramic kilns. Background Technology
[0002] A kiln is a furnace used for firing ceramics and sculptures or for fusing enamel onto the surface of metal objects. It is typically constructed of brick and stone and can be made in various sizes to meet different needs. It can be powered by combustible gas, oil, or electricity.
[0003] Currently, when a ceramic kiln is empty, the lack of brick blanks to carry away heat causes the heat from the high-temperature zone to be drawn to the exhaust section, resulting in a rapid increase in the temperature of the exhaust section. At this time, it is necessary to manually open the emergency handling hole of the exhaust section to allow cold air to be drawn into the kiln or adjust the position of the baffle plate in order to quickly reduce the temperature of the front zone. However, this manual control method is quite inconvenient. Utility Model Content
[0004] To address the problem of inconvenient operation of existing air supply systems, this utility model provides an automatic air supply system for ceramic kilns.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] An automatic air supply system for a ceramic kiln includes an air supply component and a kiln body. A pair of connecting air boxes are respectively provided on one side of the air supply component. The air supply component is interconnected with the kiln body through the connecting air boxes. A fan blade damper is rotatably connected inside one of the connecting air boxes. One end of the fan blade damper extends into the interior of the air supply component and is connected to a sprocket. A speed reducer is installed on the outer wall of the air supply component. The output end of the speed reducer extends into the interior of the air supply component and is driven by an output gear. A double-row chain is fitted between the output gear and the sprocket, and the two are connected by the double-row chain drive.
[0007] Furthermore, a motor is installed on one side of the reducer, and the output end of the motor is connected to the input end of the reducer.
[0008] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the motor enables it to provide kinetic energy output for the reducer.
[0009] Furthermore, square flanges are installed on adjacent sides of each pair of connecting air boxes, and the pair of connecting air boxes are interconnected through the square flanges.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the use of square flanges makes the two sets of connecting air boxes form a stable connection structure, and facilitates the disassembly and maintenance of the two sets of connecting air boxes.
[0011] Furthermore, the connecting wind box includes a box body, and a partition is installed inside the box body. One side of the partition has a hole that matches the wind blade damper.
[0012] The advantage of adopting the above-mentioned further solution is that the internal space of the box can be divided by setting up partitions.
[0013] Furthermore, the wind vane and the partition are staggered and form a sealing structure, which is located at the center of the connecting wind box.
[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of the sealing structure, it is easy to close the fan blades of the motor, and cold air from the outside cannot enter the kiln, thus ensuring the airtightness of the kiln and maintaining the stability of the pressure and atmosphere inside the kiln.
[0015] Furthermore, a signal receiver is installed on the outer wall of the reducer, and a control main board is provided inside the signal receiver. The motor is electrically connected to the control main board and is controlled by the control main board.
[0016] The beneficial effect of adopting the above-mentioned further solution is that by installing and using a signal receiver, it is convenient to receive empty kiln signals, thereby driving the motor to perform corresponding actions.
[0017] Furthermore, a seated bearing is installed on one side of the air supply assembly, and the air supply assembly is rotatably connected to the wind vane through the seated bearing.
[0018] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of bearing mounts helps to improve the stability of the wind turbine's rotation.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This automatic air supply system for ceramic kilns receives torque from the motor via a reducer, allowing the reducer's output to drive the output gear to rotate. This, combined with a double-row chain drive, causes the sprocket to rotate the damper blades inside the air box. When the kiln is empty, the motor receives an empty kiln signal and activates, transmitting mechanical energy to move the damper blades. When the damper blades open to a certain angle, the kiln is under negative pressure, drawing in outside cold air and lowering the kiln temperature. When the kiln resumes production after being empty, the motor receives a signal to close the damper blades, preventing outside cold air from entering the kiln and ensuring its airtightness, thus maintaining stable pressure and atmosphere within the kiln.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0028] Please see Figures 1-5This utility model provides a technical solution: an automatic air supply system for a ceramic kiln, including an air supply component 100 and a kiln body 800. A pair of connecting air boxes 300 are respectively provided on one side of the air supply component 100. The air supply component 100 is interconnected with the kiln body 800 through the connecting air boxes 300. A fan blade damper 900 is rotatably connected inside one of the connecting air boxes 300. One end of the fan blade damper 900 extends into the interior of the air supply component 100 and is connected to a sprocket 400. A reducer 1000 is installed on the outer wall of the air supply component 100. The output end of the reducer 1000 extends into the interior of the air supply component 100 and is connected to an output gear. A double-row chain 600 is sleeved between the output gear and the sprocket 400, and the system is connected via the double-row chain 600. The reducer 1000 receives torque from the motor 700. The torque conveying system allows the output end of the reducer 1000 to drive the output gear to rotate. Combined with the transmission of the double-row chain 600, the sprocket 400 drives the damper 900 to rotate inside the connecting air box 300. When the kiln is empty, the motor 700 receives an empty kiln signal and drives the motor to move. This mechanical energy transmission causes the damper 900 to move as well. When the damper 900 opens to a certain angle, the kiln is under negative pressure, drawing in outside cold air and lowering the kiln temperature. Furthermore, when the kiln resumes production after being empty, the motor 700 receives a signal and drives the motor to close the damper 900, preventing outside cold air from entering the kiln. This ensures the kiln's airtightness and maintains stable pressure and atmosphere within the kiln.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] As an embodiment of this utility model, a motor 700 is further installed on one side of the reducer 1000. The output end of the motor 700 is connected to the input end of the reducer 1000. Through the installation and use of the motor 700, it provides kinetic energy output to the reducer 1000. A pair of connecting air boxes 300 are respectively installed on adjacent sides. The pair of connecting air boxes 300 are interconnected through the square flanges 200. Through the connection of the square flanges 200, the two sets of connecting air boxes 300 form a stable connection structure and facilitate the disassembly and maintenance of the two sets of connecting air boxes 300. The connecting air box 300 includes a box body 3001. A partition 3002 is installed inside the box body 3001. A hole that matches the fan blade damper 900 is opened on one side of the partition 3002. Through the setting of the partition 3002, the internal space of the box body 3001 can be divided.
[0031] As an embodiment of this utility model, the damper 900 and the partition 3002 are staggered and form a sealing structure. The sealing structure is located at the center of the connecting air box 300. By setting the sealing structure, it is easy to close the damper 900 when the motor 700 is turned off, so that cold air from the outside cannot enter the kiln. This ensures the airtightness of the kiln and maintains the stability of the pressure and atmosphere inside the kiln. A signal receiver is installed on the outer wall of the reducer 1000. The signal receiver has a control board inside. The motor 700 is electrically connected to the control board and is controlled by the control board. By installing and using the signal receiver, it is easy to receive the empty kiln signal, thereby driving the motor 700 to perform the corresponding action.
[0032] As an embodiment of this utility model, a seated bearing 500 is further installed on one side of the air supply assembly 100. The air supply assembly 100 is rotatably connected to the fan blade damper 900 through the seated bearing 500. The installation and use of the seated bearing 500 helps to improve the rotational stability of the fan blade damper 900.
[0033] Specifically, the working principle of this automatic air supply system for ceramic kilns is as follows: When the kiln is running empty, the motor 700 receives an empty kiln signal and drives the motor to operate. The reducer 1000 receives the torque from the motor 700, causing the output gear of the reducer 1000 to rotate. This, combined with the transmission of the double-row chain 600, causes the sprocket 400 to drive the damper 900 to rotate inside the air box 300. When the damper 900 opens to a certain angle, the kiln is under negative pressure, and cold air from outside is drawn into the kiln. This achieves the purpose of reducing the temperature inside the kiln. Secondly, when the kiln ends its empty state and resumes production, the motor 700 will also receive a signal, driving the motor 700 to close the damper 900, preventing cold air from entering the kiln. This ensures the airtightness of the kiln, thereby maintaining the stability of the pressure and atmosphere inside the kiln. Furthermore, the use of the square flange 200 connects the two sets of connecting air boxes 300 to form a stable connection structure, facilitating the disassembly and maintenance of the two sets of connecting air boxes 300. The installation and use of the signal receiver facilitates the reception of the empty kiln signal, thereby driving the motor 700 to perform the corresponding actions.
