Description

Technical Field

[0001] The invention relates to the technical field of kilns, and in particular to a control system and method for a pottery pot firing kiln. Background Art

[0002] The tunnel kiln is generally a long straight passage with fixed kiln walls and kiln roofs on both sides and the top (the top can be flat or arched). The kiln cars are running on the tracks at the bottom. The kiln cars are loaded with fired products, which enter the kiln head and exit the kiln tail in turn. The kiln body constitutes a fixed preheating zone, a firing zone and a cooling zone, which are usually called the "three zones" of the tunnel kiln. The high-temperature flue gas generated by combustion flows along the tunnel toward the kiln head at the chimney at the front end of the tunnel kiln or under the action of the induced draft fan, and gradually preheats the products entering the kiln. This section constitutes the preheating zone of the tunnel kiln. The middle of the tunnel kiln is the firing zone. Cold air is blown into the kiln tail of the tunnel kiln to cool the products in the last section of the tunnel kiln. After the cold air is heated by the products, it is drawn out and sent to the drying kiln as a heat source for drying the green billets. This section constitutes the cooling zone of the tunnel kiln.

[0003] Kilns are closely related to human civilization. Our ancestors used kilns to burn various daily necessities very early. As humans entered the industrial society, kilns have developed rapidly. They also play an increasingly important role in various industries. In order to make the kiln burn satisfactory products, it is necessary to control its firing process. In the kiln firing process, temperature control is an extremely important link. The kiln operating temperature, as the most important parameter, directly affects the production quality of kiln products.

[0004] For example, in the invention document of Chinese patent publication number CN107560446A, a fully automatic control system and control method for a continuous production kiln are provided, wherein each spray gun is independently equipped with a pulse actuator, a proportional valve, an electromagnetic shut-off valve and an ignition detection controller, a temperature detection device detects the current firing condition of the product and feeds back to the PLC control system, the PLC control system calculates the control instruction according to the final firing requirements of the product and the feedback of the current firing condition, the pulse actuator, the proportional valve, the electromagnetic shut-off valve and the ignition detection controller automatically control the spray gun action according to the instruction, and adjusts the firing of the product;

[0005] Undoubtedly, the invention, by setting up a PLC control system and a pulse actuator, automatically controls in real time according to the current firing status of the product the number of burners opened, the number of times each burner cycles within a certain period of time, the duration of each operation, and the number of spray guns required for a single set of cycle pulses, thereby adjusting the firing of the product by the kiln in real time and reasonably controlling the firing temperature of the pottery pot.

[0006] However, when the object to be fired is a large pottery jar, although there is a long preheating stage in the tunnel kiln, due to its sealed bottom and usually placed on stacked bricks and on the surface of the kiln car, it will still be heated unevenly during the preheating stage, which greatly affects the quality of the fired product and the success rate of firing. Especially in the process of the temperature in the preheating zone from 150℃ to 200℃, there is actually a temperature jump from 170℃ to above. It is preliminarily estimated that this is because during the preheating and drying process of the pottery jar, after a large amount of water escapes, it will leave more micropores on the surface of the pottery jar, and the evaporation of water will take away some heat. At about 170℃, the water has basically escaped completely, which will cause the temperature of the pottery jar to increase rapidly, resulting in a jump in the preheating temperature of the pottery jar. In this process, the pottery pot is extremely fragile. If the preheating temperature of the pottery pot cannot be well controlled, there will be a large temperature difference between the inside and outside of the pottery pot (preheating mainly transfers heat through thermal convection. If the temperature inside the pottery pot is low, the cold air will gather at the bottom of the pottery pot due to the large space inside the pottery pot, causing a temperature difference between the inside and outside of the pottery pot). Some pottery pots are very easy to break in this process, and if the micropores on the surface of the pottery pot are not well dredged, some of the micropores will be blocked, affecting the overflow of water in the pottery pot. After the temperature rises further, the water will further expand, which is easy to cause product defects. In severe cases, it is even related to the temperature difference between the inside and outside of the pottery pot, further affecting the success rate of burning paper in the pottery pot. Therefore, there is an urgent need for a device that can solve the problem of pottery pot body rupture due to uneven heating during the preheating process of the pottery pot. Summary of the invention

[0007] The invention provides a control system and method for a pottery pot firing kiln, aiming to solve the problem of pottery pot body cracking due to uneven heating during the pottery pot firing process.

[0008] In order to achieve the above objectives, this solution provides the following technical solutions:

[0009] A pottery pot firing kiln control system, comprising a kiln body and a track, wherein the track is fixed on a base in the kiln body, and further comprising:

[0010] The transport unit includes a kiln car, insulation bricks and a fixed plate. The kiln car slides along the track, and the insulation bricks and the fixed plate are placed on the surface of the kiln car in sequence. The fixed plate is fixed on the upper surface of the kiln car.

[0011] The heat preservation unit includes a sand sealing plate and a sand sealing groove, wherein the sand sealing groove is fixed at the lower end of the side wall of the kiln body, the sand sealing groove is filled with sand grains, the sand sealing plate is fixed at the side of the kiln car, and the sand sealing plate is inserted into the sand grains in the sand sealing groove;

[0012] The regulating unit comprises a frame, a liquid storage part and a heat conducting rod, wherein the frame comprises a support rod and a support plate, the support rod is fixed on the fixed plate, the support plate is fixedly connected to the support rod and is located above the pottery pot placed on the fixed plate, the upper end of the heat conducting rod is fixed to the lower surface of the support plate, the lower end of the heat conducting rod is located in the pottery pot to be processed, the top end of the heat conducting rod is communicated with the liquid storage part, the liquid storage part is fixed to the side of the top of the heat conducting rod, a liquid inlet is opened at the top of the liquid storage part, a sealing cover with a detachable sealing connection is provided at the liquid inlet, a trumpet-shaped air release port with a narrow inner side and a wide outer side is opened on the side of the heat conducting rod, a space for loading clean water is provided inside the liquid storage part, a cavity is opened in the heat conducting rod to communicate the liquid storage part with the air release port, and a sealing cover for closing the liquid inlet is fixedly connected to the top of the heat conducting rod;

[0013] It also includes an air plug, a fixing part and a high temperature resistant elastic part which makes the air plug fit tightly to the vent in the initial state. The fixing part is fixed on the cavity wall in the heat conducting rod. One end of the elastic part is fixed on the fixing part and the other end is fixed on the air plug. The air plug is located in the vent.

[0014] Principle and beneficial technical effects of this technical solution:

[0015] Because the kiln car slides along the track, the movement of the kiln car on the track in the kiln furnace can make the kiln car pass through the preheating zone, the firing zone and the cooling zone, and the pottery pots on the kiln car can be well processed. Because it includes a sand sealing plate and a sand sealing groove, the sand sealing groove is fixed at the lower end of the side wall of the kiln body, the sand sealing groove is filled with sand, the sand sealing plate is fixed to the side of the kiln car, and the sand sealing plate is inserted into the sand in the sand sealing groove, so the kiln car can also ensure the sealing effect during the movement, and the heat insulation effect is first-class, reducing the heat exchange between the hot air on the upper surface of the kiln car and the air on the lower surface of the kiln car, effectively protecting the lower surface of the kiln car from damage caused by high temperature, and avoiding the temperature difference caused by the entry of cold air.

[0016] Because one end of the heat conductive rod is fixed on the lower surface of the support plate and the other end of the heat conductive rod extends into the pottery pot to be processed, the heat conductive rod will heat up after being roasted, thereby reducing the temperature difference inside and outside the pottery pot through heat conduction, making the pottery pot heated more evenly when the temperature in the kiln rises.

[0017] Because a trumpet-shaped vent is provided on the side of the heat-conducting rod, a cavity is provided inside the heat-conducting rod to connect the liquid storage part and the vent, and a sealing cover arranged at the liquid inlet can close the liquid inlet; it also includes an air plug, a fixing part, and a high-temperature resistant elastic part that makes the air plug fit tightly against the vent in the initial state, the fixing part is fixed on the inner wall of the cavity in the heat-conducting rod, one end of the elastic part is fixed on the fixing part, and the other end is fixed on the air plug. Therefore, when the liquid in the liquid storage part is evaporated into gas due to high temperature, as the temperature increases, the gas pressure in the cavity will gradually increase (forming superheated steam or saturated steam), thereby pushing the air plug to move outward, and the high-temperature gas The gas is sprayed out from the vent, which accelerates the air flow in the pottery pot and further reduces the temperature difference between the inside and outside of the pottery pot (equivalent to transferring the heat from the top of the pottery pot to the inside of the pottery pot and spraying it out in the form of superheated steam or saturated steam), so that the temperature difference between the inner and outer walls of the pottery pot is controlled within 20°C (when superheated steam or saturated steam comes into contact with the inner wall of the pottery pot, the air pressure is lower than that in the air, and the temperature in the pottery pot is also around 170°C, which will quickly escape from the mouth of the pottery pot). The blowing of the gas also helps to clear the micropores on the pottery pot during the heating process, thereby reducing the possibility of the pottery pot ruptureing due to heating.

[0018] This solution ensures the sealing effect of the kiln car during its movement, and has a first-class heat insulation effect, reducing the heat exchange between the hot air on the upper surface of the kiln car and the air on the lower surface of the kiln car, effectively protecting the lower surface of the kiln car from damage caused by high temperature; reducing the temperature difference between the inside and outside of the pottery pot, so that the pottery pot is heated more evenly when the temperature in the kiln rises; accelerating the air flow in the pottery pot, further reducing the temperature difference between the inside and outside of the pottery pot, and controlling the temperature difference between the inner wall and the outer wall of the pottery pot within 20°C; it is helpful to clear the micropores on the pottery pot during the heating process, reducing the possibility of the pottery pot ruptured during heating, thereby solving the problem of pottery pot rupture due to uneven heating during the firing process.

[0019] Furthermore, it also includes a support frame for supporting the sand sealing groove, and the support frame is fixed on the side wall of the kiln body.

[0020] Beneficial effect: more stable and better supporting effect can be achieved.

[0021] Furthermore, the insulation bricks are made of clay refractory bricks.

[0022] Beneficial effect: It not only avoids the problem of ordinary standard bricks increasing the weight of the kiln car, causing broken materials to leak into the kiln bottom along the brick seams during operation, but also avoids the problem of ordinary standard bricks having a large thermal conductivity, causing a large amount of heat to be dissipated under the car, resulting in energy waste.

[0023] Furthermore, it also includes cooling spray holes arranged in the cooling zone of the kiln body.

[0024] Beneficial effects: Good cooling effect.

[0025] Furthermore, the cooling spray holes are evenly arranged on the upper side and the lower side of the kiln body of the cooling zone.

[0026] Beneficial effect: The cooling spray holes arranged in multiple directions can achieve good cooling effect.

[0027] Furthermore, the cooling nozzles use pulsed airflow.

[0028] Beneficial effect: Pulse airflow can reduce the impact of the hotter airflow from the firing zone entering the cooling zone after passing through the gap.

[0058] Figure 1 It is the front view of the present invention;

[0059] Figure 2 is a cross-sectional view of the heat conducting rod in the present invention;

[0060] Figure 3 A three-dimensional schematic diagram of a tunnel kiln. DETAILED DESCRIPTION

[0061] The following is a further detailed description through specific implementation methods:

[0062] The figure numerals in the drawings of the specification include: 1. kiln body; 2. track; 3. sand sealing groove; 4. support frame; 5. kiln car; 6. insulation brick; 7. fixing plate; 8. pad brick; 9. sand sealing plate; 10. support rod; 11. support plate; 12. heat conducting rod; 13. air plug; 14. elastic part; 15. fixing part.

[0063] The examples are as follows:

[0064] A pottery kiln control system includes a kiln body 1, a track 2, a flame spray gun and a control system for controlling the temperature of flames sprayed from the flame spray gun. The track 2 is fixed on a base inside the kiln body 1. The control system also includes:

[0065] The transport unit comprises a kiln car 5, insulating bricks 6 and a fixed plate 7. The kiln car 5 slides along the track 2. The surface of the kiln car 5 is sequentially provided with insulating bricks 6 and fixed plates 7. The insulating bricks 6 are made of clay refractory bricks instead of ordinary bricks, so as to avoid the increase in energy loss caused by the increase in the self-weight of the kiln car 5 due to the increase in the weight of the kiln car 5 caused by ordinary standard bricks, the large thermal conductivity of ordinary standard bricks during the operation of the kiln car 5, and the large amount of heat dissipated under the car, resulting in energy waste; stacked pad bricks 8 are placed on the fixed plate 7, and the pottery pot is placed on the pad bricks 8. The structure is simple, so that the bottom of the pottery pot can also be baked and formed by the high temperature in the kiln; there is a gap of 0.5 cm to 1 cm between the insulating bricks 6. The insulating bricks 6 will expand and contract with heat, so a certain gap needs to be left between the insulating bricks 6 to avoid the insulation bricks 6 expanding under high temperature and causing the brick body to break, but the gap should not be too large, thereby reducing the insulation effect, so that the surface of the kiln car 5 is baked at too high a temperature.

[0066] Because the upper surface of the kiln car 5 needs to be roasted at high temperature in the kiln, the bolts and welding rods used in the connection method are all high temperature resistant, such as 314 stainless steel bolts, e316 welding rods, etc.

[0067] The heat preservation unit includes a sand sealing plate 9 and a sand sealing groove 3. The sand sealing groove 3 is bolted to the lower end of the side wall of the kiln body 1. The support frame 4 for supporting the sand sealing groove 3 is bolted to the side wall of the kiln body 1 and is placed at the lower end of the sand sealing groove 3 to provide good support for the sand sealing groove 3. Sand grains are filled in the sand sealing groove 3. The side surface of the sand sealing plate 9 is bolted to the side surface of the kiln car 5. The sand sealing plate 9 is inserted into the sand grains in the sand sealing groove 3. The sand grains can pass through a 0.4*0.4cm filter screen. The sand grains used in the sand sealing groove 3 cannot be too large. If they are too large, they will be plowed up by the sand sealing plate 9 of the kiln car 5 passing by. There are gaps between the overly large sand grains. If there are gaps, they cannot play a sealing role, and cannot prevent the cold air under the car from entering the kiln chamber or the high-temperature gas in the kiln chamber from squeezing into the bottom of the car. When the kiln car 5 is running, the sand sealing plate 9 moves in the sand sealing groove 3 and forms a good heat insulation layer between the sand particles, thereby ensuring the sealing effect of the upper and lower surfaces of the kiln car 5. The heat insulation effect is first-class, reducing the heat exchange between the hot air on the upper surface of the kiln car 5 and the air on the lower surface of the kiln car 5, and effectively protecting the lower surface of the kiln car 5 from damage caused by high temperature.

[0068] The regulating unit includes a frame, a liquid storage part and a heat conducting rod 12. The frame includes a support rod 10 and a support plate 11. The support rod 10 is bolted to the fixing plate 7. The support plate 11 is bolted to the support rod 10. The upper end of the heat conducting rod 12 is fixed to the lower surface of the support plate 11. The lower end of the heat conducting rod 12 extends into the pottery pot to be processed. The top of the heat conducting rod 12 is connected to the liquid storage part. The liquid storage part is fixed to the side of the top of the heat conducting rod 12. A trumpet-shaped air vent is opened on the side of the heat conducting rod 12. A cavity is opened in the heat conducting rod 12 to connect the liquid storage part and the air vent. A liquid inlet is opened at the top of the liquid storage part. A sealing cover for closing the liquid inlet is bolted to the opening; it also includes an air plug 13, a fixing part 15 and a high-temperature resistant elastic part 14 (made of high-temperature alloy, in accordance with GB / 14992, with the grade of GH5605, 1000°C, used under light thrust conditions, the highest temperature in this scheme is around 1000°C, and under this working condition, there is no external force and it can be used multiple times), the fixing part 15 is welded to the inner wall of the cavity in the heat-conducting rod, one end of the elastic part 14 is welded to the fixing part 15, and the other end is welded to the air plug 13. Therefore, when the liquid in the cavity of the heat conducting rod 12 is subjected to high temperature, it evaporates into gas. When the temperature is higher, the gas pressure in the cavity will gradually increase, thereby pushing the gas plug 13 to move outward, and the high-temperature gas is ejected from the vent, accelerating the air flow in the ceramic pot, further reducing the temperature difference between the space inside and outside the ceramic pot, and the blowing of the gas also helps to clear the micropores on the pot body during the heating process of the ceramic pot, which helps to reduce the possibility of the ceramic pot rupture due to heating.

[0069] Cooling spray holes are arranged on the upper, lower, left and right sides of the inner wall of the kiln body 1 of the cooling zone, and the cooling spray holes use pulse airflow to cool the product.

[0070] A pottery pot firing kiln control method, comprising:

[0071] Step S10: placing the pottery pot to be fired on the pad brick 8 so that the bottom of the pottery pot can also be baked and formed by the high temperature in the kiln;

[0072] Step S20: placing the rod feet of the support rod 10 on the fixing plate 7 to achieve the positioning of the rack;

[0073] Step S21: Extend one end of the heat conducting rod 12 into the inner space of the pottery pot, and fix the other end of the heat conducting rod 12 to the lower end of the support plate 11 to achieve the positioning of the heat conducting rod 12;

[0074] Step S22: introducing liquid into the liquid inlet of the heat conducting rod 12;

[0075] Step S30: driving the kiln car 5 into the kiln;

[0076] Step S40: closing the kiln door to isolate the heat exchange between the inside and outside of the kiln to facilitate subsequent high-temperature firing;

[0077] Step S50: Start the control system, turn on the flame spray gun, and make the pottery pots on the kiln car 5 of the firing belt contact the high temperature to start firing;

[0078] Step S60: At this time, the heat conducting rod 12 in the preheating zone is heated by the high temperature in the kiln, and the temperature difference between the inside and outside of the pottery pot is reduced by heat conduction;

[0079] Step S70: The gas generated by the evaporation of the liquid in the inner cavity of the heat conducting rod 12 overflows the gas plug 13. The high-temperature steam overflowing the gas plug 13 accelerates the air flow in the pottery pot, which is beneficial to clearing the micropores on the pottery pot during the heating process.

[0080] Step S80: After the kiln car 5 passes through the preheating zone and enters the firing zone, the smoke exhauster is turned on to exhaust the smoke;

[0081] Step S90: After the kiln car 5 passes through the firing zone and enters the cooling zone, the flame spray gun is turned off and the rapid cooling fan is turned on to gradually cool the pottery pot, which is conducive to the molding of the pottery pot and reduces the probability of the pottery pot breaking;

[0082] Step S100: Open the kiln door and send the kiln car 5 out of the kiln;

[0083] Step S110: taking out the heat conducting rod 12 to facilitate taking out the pottery pot in the subsequent process;

[0084] Step S120: remove the pottery jar.

[0085] Step S130: Clean the debris under the insulation bricks 6 to prevent the debris from clogging the gaps between the insulation bricks 6 and eliminate the possibility of unevenness of the insulation bricks 6.

[0086] Compared with the traditional solution, the present invention solves the problem of pottery jar cracking due to uneven heating during the firing process, thereby improving the molding quality of the pottery jar, increasing the product yield, and avoiding the problem of broken pieces of pottery jar in the kiln affecting the safe operation of the equipment in the kiln.

[0087] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
