DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figures 1-16 As shown, an embodiment of the present invention provides a ceramic energy-saving firing kiln, including a kiln assembly 1, the kiln assembly 1 includes a kiln body 101, an inner wall of the kiln body 101 is provided with a heating wire 102, and the front of the kiln body 101 is rotatably connected to a kiln door 105;

[0041] refer to Figure 1 The kiln body 101 is a hollow rectangular parallelepiped as a whole. There is space inside the kiln body 101 to accommodate the base 106 and the ceramic body to ensure the stability of the firing process; the heating wire 102 is used to convert electrical energy into thermal energy. The number of heating wires 102 can be freely selected according to the size of the kiln body 101; the kiln door 105 is used to cooperate with the kiln body 101 to form an insulation space, providing the necessary conditions for maintaining the firing temperature; in order to detect the temperature inside the kiln body 101, a temperature sensor can be used for real-time monitoring to ensure the accuracy of the firing temperature.

[0042] An air inlet channel is provided on the top wall of the kiln body 101, to which an air inlet shell 103 is fixedly connected. A horizontal opening is provided on the side wall of the air inlet shell 103. A limiting rail 108 is provided at the lower portion of the kiln body 101. A travel wheel frame 107 is provided inside the limiting rail 108. A placement base 106 is provided on the upper portion of the travel wheel frame 107. The placement base 106 cooperates with the kiln body 101. An exhaust port 109 is provided at the lower portion of the kiln body 101. An air choke 104 is fixedly connected to the inner wall of the kiln body 101 and located below the heating wire 102. An air choke groove 1041 is provided on the upper portion of the air choke 104. A diversion component for separating the airflow is provided inside the placement base 106.

[0043] refer to Figure 3 、 Figure 4 The air intake channel is used for air to enter the air intake shell 103, and then be discharged from the horizontal opening of the air intake shell 103. The air flow will contact the heating wire 102, so that the air flow is fully heated by the heating wire 102, and a part of the air flow enters the wind blocking groove 1041. The wind blocking groove 1041 blocks the air flow along the side wall and slows down the air flow rate, so that more air flow acts on the embryo; the walking wheel frame 107 can be moved out of or into the kiln body 101, providing operational convenience for taking out and placing the embryo; the placement base 106 is the same as the side wall of the kiln body 101, and both have the function of heat preservation; the exhaust port 109 is used for exhaust gas discharge. In the initial stage, the exhaust gas contains moisture. The exhaust port 109 is long and can discharge the water-containing exhaust gas to the greatest extent, shortening the embryo drainage process and improving the firing efficiency.

[0044] The diverter assembly includes a diverter plate 602 and a lifting member 601 slidably mounted on the base 106. The lifting member 601 is located below the diverter plate 602. A diverter spring 1 603 is sleeved on the rod-shaped portion of the lifting member 601. A diverter spring 2 604 is fixedly connected to the end of the lifting member 601.

[0045] refer to Figure 16 As the placement base 106 moves into the kiln body 101, the lifting member 601 will contact the inner wall of the kiln body 101 and move into the placement base 106. The diverter plate 602 can be pushed up by the inclined surface on the upper part of the lifting member 601. When the lifting member 601 moves, it will squeeze the diverter spring 1 603 and the diverter spring 2 604. The diverter spring 1 603 and the diverter spring 2 604 will be compressed. The ends of the diverter spring 1 603 and the diverter spring 2 604 both have a vortex part for better contact with the cavity in the placement base 106. This part can provide a certain support force for the diverter plate 602 to ensure the stability of the diverter plate 602.

[0046] Also includes:

[0047] The exhaust assembly 3 is provided on the outer wall of the kiln body 101 and is used to guide and utilize the high-temperature exhaust gas. The exhaust assembly 3 includes an exhaust gas insulation shell 301 adapted to the kiln body 101. The lower portion of the exhaust gas insulation shell 301 is provided with an inlet 303, and the upper portion of the exhaust gas insulation shell 301 is fixedly connected to an exhaust channel 302.

[0048] refer to Figure 2 、 Figure 7 、 Figure 8 During the exhaust process, the exhaust gas will enter the exhaust gas insulation shell 301 from the inlet 303, and then be discharged from the exhaust channel 302 to enter the subsequent exhaust gas treatment device. The exhaust gas insulation shell 301 has the function of insulation. Since the exhaust gas insulation shell 301 is located on the outside of the kiln body 101, therefore, under the premise of the insulation of the kiln body 101 itself, the exhaust gas insulation shell 301 can also provide insulation effect, further reducing the temperature loss, suitable for the insulation stage of the firing process, reducing the energy consumption of maintaining temperature, and more energy-saving to use; since there is a certain amount of dust in the exhaust gas, a filter box can be added at the inlet 303 to realize the dust filtering function, and you can choose whether to add it.

[0049] Energy-saving component 2, energy-saving component 2 is arranged on the outside of the kiln furnace body 101, and is used to absorb the exhaust gas temperature in the exhaust gas insulation shell 301; energy-saving component 2 includes an insulation water tank 202, and a circulating water pump 203 is fixedly installed on the front of the insulation water tank 202. The water outlet of the circulating water pump 203 is connected to the heat exchange shell 205 through the liquid inlet pipe 204, and the pumping end of the circulating water pump 203 is connected to the insulation water tank 202 through a pipeline. The heat exchange shell 205 is connected to the heat absorption pipe 206 through the pipeline, and the end of the heat absorption pipe 206 is connected to the insulation water tank 202 through the return pipe 208; the longitudinal section of the heat exchange shell 205 is an inverted U-shape, and the lower part of the intermediate shell 504 is provided with two channels, and the heat exchange shell 205 can extend into the two channels. The heat exchange shell 205 is located below the reversing member 503;

[0050] refer to Figure 5 、 Figure 6 、 Figure 8The insulated water tank 202 has the function of heat preservation. The insulated water tank 202 is also provided with a water inlet pipe and a water outlet pipe for adding water to the insulated water tank 202 or discharging the water in the insulated water tank 202 for use. When the water circulation is required, the circulating water pump 203 works under the action of the external power supply and the controller to inject the water in the insulated water tank 202 into the heat exchange shell 205 through the liquid inlet pipe 204, and then flows into the heat absorption pipe 206. The heat absorption pipe 206 has a long overall length and is located in the exhaust gas insulation shell 301. The high-temperature exhaust gas in the exhaust gas insulation shell 301 will exchange heat with the heat absorption pipe 206 to heat the water flow in the heat absorption pipe 206. The heat absorption of the water flow can reduce the temperature of the exhaust gas, thereby avoiding the waste of temperature in the exhaust gas. The heated water flows back into the insulated water tank 202 through the return liquid pipe 208 again, and the insulated water tank 202 keeps the water with heat warm.

[0051] In addition, since the heat exchange shell 205 is located inside the intermediate shell 504, the air flow circulating in the intermediate shell 504 will contact the heat exchange shell 205. After the heat of the exhaust gas in the early heating process is absorbed by the water, the water temperature rises. During the warming stage, the temperature of the heat exchange shell 205 will rise synchronously with the water temperature, and the normal temperature air flow in the intermediate shell 504 will be heated to achieve the preheating function, avoiding excessive temperature difference between the embryo temperature and the incoming air flow temperature, resulting in a decrease in the embryo firing quality, thereby improving the firing quality; the shape of the longitudinal section of the heat exchange shell 205 is an inverted U shape, and the part of the heat exchange shell 205 extending into the two channels of the intermediate shell 504 will increase the contact area between the air flow and the heat exchange shell 205, thereby improving the efficiency of heat exchange.

[0052] A bottom frame 201 is provided at the bottom of the heat-insulating water tank 202. The bottom frame 201 is located outside the kiln body 101. A protective shell 209 is fixedly connected to the front of the heat-absorbing pipe 206. A top shell 207 is fixedly connected to the protective shell 209. The top shell 207 is located above the heat-absorbing pipe 206. The longitudinal cross-section of the top shell 207 is C-shaped, and the width of the top shell 207 occupies half the width of the inner cavity of the exhaust gas insulation shell 301.

[0053] refer to Figure 5 The base frame 201 provides support for the insulated water tank 202 to prevent the insulated water tank 202 from being hit; the protective shell 209 is used to provide protection for the heat absorption tube 206 to ensure the stable installation of the heat absorption tube 206; the C-shaped top shell 207 is used to block the flow of exhaust gas, so that the exhaust gas can flow backward downward, and the backward exhaust gas and the downstream exhaust gas collide with each other, causing the exhaust gas flow rate to decrease, and the exhaust gas is in full contact with the heat absorption tube 206, thereby improving the heat exchange efficiency; the top shell 207 will occupy half of the inner cavity width of the exhaust gas insulation shell 301, and the air flow in the unoccupied inner cavity can flow normally, ensuring the most basic exhaust gas flow rate.

[0054] The pressure maintaining component 4 is provided in the exhaust passage 302 and is used to provide adjustable resistance for the exhaust gas discharged from the exhaust passage 302;

[0055] The pressure-maintaining assembly 4 includes a fixed frame 401 fixedly installed in the exhaust channel 302, a connecting rod 408 is slidably connected in the fixed frame 401, one end of the connecting rod 408 is fixedly connected to the pressure-maintaining plate 402, the pressure-maintaining plate 402 is adapted to the fixed frame 401, the other end of the connecting rod 408 is fixedly connected to the end piece 403, an adjusting nut 406 is threadedly connected to the connecting rod 408, a pressure sleeve 405 is movably sleeved on the connecting rod 408, the pressure sleeve 405 is located on the side of the adjusting nut 406 close to the fixed frame 401, a pressure-maintaining spring 407 is sleeved on the connecting rod 408 and located between the pressure sleeve 405 and the fixed frame 401, a scale bar 404 is fixedly connected between the end piece 403 and the pressure-maintaining plate 402, and the scale bar 404 passes through the pressure sleeve 405;

[0056] refer to Figure 8 、 Figure 9 、 Figure 10 During the pressure maintaining operation, when the exhaust gas flows from bottom to top into the exhaust channel 302, it will be blocked by the pressure maintaining plate 402, thereby increasing the gas pressure in the kiln body 101, the exhaust gas insulation shell 301 and the exhaust channel 302, ensuring that the exhaust gas can enter the reversing shell 5032 from the connecting pipe 5031, and also ensuring that the exhaust gas can fully contact with the heat absorption pipe 206; due to the increase in gas pressure, the gas pressure will overcome the elastic force of the pressure maintaining spring 407, so that the pressure maintaining plate 402 is away from the fixed frame 401, and the exhaust gas will be discharged from the gap between the pressure maintaining plate 402 and the fixed frame 401, completing the smooth release of the exhaust gas; in order to adapt to the temperature of the exhaust gas, the pressure maintaining spring 407 should be made of a material that can adapt to high temperatures, such as a nickel-based alloy spring;

[0057] When the holding pressure needs to be adjusted, the position of the pressure sleeve 405 on the connecting rod 408 can be changed by rotating the adjusting nut 406. When the adjusting nut 406 is tightened, the pressure sleeve 405 is close to the fixed frame 401, the deformation of the compressed pressure holding spring 407 increases, and the reaction force provided by the pressure holding spring 407 increases, so that a larger air pressure is required to overcome the elastic force; conversely, the deformation of the pressure holding spring 407 can be reduced, and a smaller air pressure can overcome the elastic force, thereby realizing the function of adjusting the air pressure; in order to improve the adjustment accuracy, according to the position of the pressure sleeve 405 on the scale bar 404, the scale value of the pressure sleeve 405 is observed to intuitively reflect the size of the adjustment pressure.

[0058] The air intake assembly 5 is arranged at the top of the kiln body 101 and is used to add air into the kiln body 101. The air intake assembly 5 includes an intermediate shell 504 fixedly mounted on the top of the kiln body 101. A reversing member 503 is provided on the upper portion of the intermediate shell 504. An adjusting member 505 is provided on the front portion of the intermediate shell 504. The adjusting member 505 is used to control the angular position of the reversing member 503. A fan 502 is provided on the top of the intermediate shell 504. An air inlet housing 501 is provided on the upper portion of the fan 502. The reversing housing 5032 and the heat exchange housing 205 are both made of copper. The side wall of the air inlet housing 501 is provided with an opening.

[0059] refer to Figure 11 、 Figure 1 The fan 502 is used to blow external air into the intermediate shell 504, and the reversing piece 503 can change the direction of the airflow. For example, when the reversing piece 503 is in a vertical state, the airflow flows vertically downward. When the reversing piece 503 is in an inclined state, the airflow is blocked by the reversing piece 503 and then flows to the unblocked side, thereby achieving the purpose of changing the direction of the airflow; when the reversing shell 5032 is in a horizontal state, multiple reversing shells 5032 will block the upper inner cavity of the intermediate shell 504, thereby reducing the air supply volume and ensuring the stability of the input airflow. The reversing shell 5032 and the heat exchange shell 205 are both made of copper material, which has good heat exchange efficiency. It can also be replaced with other materials with good heat exchange efficiency. You can choose according to the specific situation.

[0060] The reversing member 503 includes a connecting pipe 5031 connected to the exhaust gas insulation shell 301. The end of the connecting pipe 5031 away from the exhaust gas insulation shell 301 is fixedly connected to a blocking edge 5035. The end of the connecting pipe 5031 away from the exhaust gas insulation shell 301 is rotatably connected to the reversing shell 5032. The connecting pipe 5031 extends into the reversing shell 5032. A sealing ring 5034 is provided between the blocking edge 5035 and the reversing shell 5032. The end of the reversing shell 5032 away from the connecting pipe 5031 is fixedly connected to a drive shaft 5033. The drive shaft 5033 is rotatably engaged with the intermediate shell 504.

[0061] refer to Figure 11 、 Figure 13 , the exhaust gas will enter the reversing shell 5032 through the connecting pipe 5031; since the connecting pipe 5031 is rotatably connected to the reversing shell 5032, the reversing shell 5032 can rotate, wherein the sealing ring 5034 and the blocking edge 5035 can ensure that the exhaust gas will not leak from the connection between the connecting pipe 5031 and the reversing shell 5032, thereby ensuring good sealing; the reversing shell 5032 is in the shape of a long strip as a whole, providing a good guiding effect for the flow direction of the airflow; since the temperature of the reversing shell 5032 will change with the temperature of the exhaust gas, the air flowing in the intermediate shell 504 will also be preheated by the reversing shell 5032, so that the air temperature rises, reducing heat waste and improving heat utilization.

[0062] The adjusting member 505 includes a servo motor 5051 fixedly mounted on the outside of the intermediate housing 504. The output end of the servo motor 5051 is fixedly connected to a driving pulley 5052. An intermediate pulley 5053, a driven member 5054, a passive member 5055, and an edge pulley 5056 are provided on the outside of the driving pulley 5052. The driving pulley 5052 and the intermediate pulley 5053 are driven by a synchronous belt, the intermediate pulley 5053 and the driven member 5054 are driven by a synchronous belt, the driven member 5054 and the passive member 5055 are driven by gear meshing, the passive member 5055 and the edge pulley 5056 are driven by a synchronous belt, and the intermediate pulley 5053, the driven member 5054, the passive member 5055, and the edge pulley 5056 are fixedly connected to the corresponding drive shaft 5033.

[0063] refer to Figure 12 During the adjustment operation, the servo motor 5051 works under the action of the external power supply and the controller, driving the active pulley 5052 to rotate to the required angle. The angle is controlled by the built-in encoder of the servo motor 5051, which monitors the position, speed and torque of the rotor in real time and sends the feedback signal to the controller to achieve precise control; the active pulley 5052 drives the intermediate pulley 5053 to rotate synchronously through the synchronous belt, and the intermediate pulley 5053 drives the driven member 5054 to rotate synchronously through the synchronous belt, thereby driving the active pulley 5052, the intermediate pulley 5053 and the driven member 505 4, the corresponding fixed drive shaft 5033 rotates, the driven member 5054 drives the driven member 5055 to rotate in the opposite direction through gear meshing, and the driven member 5055 drives the edge pulley 5056 to rotate in the opposite direction synchronously through the synchronous belt, thereby driving the drive shaft 5033 fixedly connected to the driving pulley 5052, the intermediate pulley 5053 and the driven member 5054 to rotate, thereby achieving symmetrical rotation of the reversing members 503 on both sides, so that the airflow can be guided to the heat exchange shell 205 by the reversing member 503, so that the airflow is fully in contact with the heat exchange shell 205 for heat exchange, thereby ensuring a good preheating effect.

[0064] Working principle: When in use, the embryo to be fired is placed on the placement base 106, and then the placement base 106 and the embryo are moved into the kiln body 101 through the walking wheel frame 107, and the kiln door 105 is closed;

[0065] The electric heating wire 102 and the fan 502 are working, and the circulating water pump 203 is working, and the water in the heat-insulating water tank 202 is injected into the heat exchange shell 205 through the liquid inlet pipe 204, and then flows into the heat absorption pipe 206. The heat absorption pipe 206 is relatively long as a whole, and the heat absorption pipe 206 is located in the exhaust gas insulation shell 301. The high-temperature exhaust gas in the exhaust gas insulation shell 301 will exchange heat with the heat absorption pipe 206, heating the water flow in the heat absorption pipe 206. The heat absorption of the water flow can reduce the temperature of the exhaust gas, thereby avoiding the waste of temperature in the exhaust gas. The heated water flows back into the heat-insulating water tank 202 again through the return liquid pipe 208, and the heat-insulating water tank 202 keeps the water with heat warm.

[0066] As the water temperature rises, during the warming stage, the temperature of the heat exchange shell 205 will rise synchronously with the water temperature. The servo motor 5051 will work to control the symmetrical rotation of the reversing members 503 on both sides, so that the airflow can be guided to the heat exchange shell 205 by the reversing members 503, so that the airflow and the heat exchange shell 205 can fully contact and exchange heat. The normal temperature airflow in the intermediate shell 504 will be heated, realizing the preheating function, avoiding a large temperature difference between the embryo body temperature and the incoming airflow temperature, which would lead to a decline in the embryo body firing quality, thereby improving the firing quality;

[0067] During the pressure-maintaining operation, when the exhaust gas flows from bottom to top into the exhaust channel 302, it will be blocked by the pressure-maintaining plate 402, thereby increasing the gas pressure in the kiln body 101, the exhaust gas insulation shell 301 and the exhaust channel 302, ensuring that the exhaust gas can enter the reversing shell 5032 from the connecting pipe 5031, and also ensuring that the exhaust gas can fully contact the heat absorption pipe 206. Due to the increase in gas pressure, the gas pressure will overcome the elastic force of the pressure-maintaining spring 407, causing the pressure-maintaining plate 402 to move away from the fixed frame 401, and the exhaust gas will be discharged from the gap between the pressure-maintaining plate 402 and the fixed frame 401, completing the smooth release of the exhaust gas.

[0068] During the cooling process, the above-mentioned circulating water pump 203 can also be repeated to release the hot water, add cold water to the insulated water tank 202, and then reabsorb the heat in the exhaust gas. The exhaust heat in the cooling stage is utilized to reduce the overall heat waste, which is very energy-saving to use.
