Description

Technical Field

[0001] The present invention relates to the technical field of industrial kilns, and in particular to a roller kiln heating system, a roller kiln heating method, a device and a computer device. Background Art

[0002] The roller kiln is a tunnel kiln with a long and narrow cross-section. It is composed of rollers arranged in parallel and crossing the cross-section of the kiln's working channel. Heating rods are laid on both the upper and lower surfaces of the roller. The battery material is placed on the roller and transported into the kiln as the rollers rotate. The firing process is completed in the kiln, so it is called a roller kiln. The traditional heating solution is that one group of heating rods corresponds to one SCR (power regulator) to heat up, and PID control is performed throughout the period. The demand for heating rods in the roller kiln is huge. Since one group of heating rods corresponds to one SCR, the demand for SCR is also very large, resulting in high production costs. Summary of the invention

[0003] In view of this, the present invention provides a roller kiln heating system, a roller kiln heating method, a device and a computer device to solve the problem of high production cost of the roller kiln due to a large number of power regulators required in the roller kiln.

[0004] In a first aspect, the present invention provides a roller kiln heating system, wherein at least a section of the kiln body of the roller kiln comprises a fixed power heater, an adjustable power heater and a controller, wherein the fixed power heater is connected to a power supply, a first switch is provided between the fixed power heater and the power supply, the fixed power heater comprises a balanced power heater and a heating power heater, wherein the heat provided by the balanced power heater is equal to the sum of the heat carried away by the gas and the heat dissipated by the kiln wall, and the heat provided by the heating power heater is equal to the sum of the heat carried away by the gas, the heat dissipated by the kiln wall and the heat required for the temperature of the structural parts of the kiln body to rise to a preset first threshold value; the adjustable power heater is connected to the power supply, a power adjustment element is provided between the adjustable power heater and the power supply; the controller is connected to the first switch for controlling the on and off of the first switch; the controller is also connected to the power adjustment element for controlling the heating power of the adjustable power heater.

[0005] The roller kiln heating system provided by the present invention comprises at least one section of the kiln body of the roller kiln including a fixed power heater, an adjustable power heater and a controller, wherein the controller can control whether the fixed power heater works by controlling the on and off of a first switch, and the controller can adjust the heating power of the adjustable power heater through a power adjustment element, and the roller kiln is heated by the fixed power heater and the adjustable power heater to achieve various temperatures required by the roller kiln. That is to say, in the roller kiln heating system provided by the present invention, not all heaters in the roller kiln are connected to the power adjustment element, thereby reducing the number of power adjustment elements installed in the roller kiln and reducing production costs.

[0006] In a second aspect, the present invention further provides a method for heating a roller kiln, wherein at least one section of the kiln body of the roller kiln comprises a fixed power heater, an adjustable power heater and a controller, wherein the fixed power heater is connected to a power supply, and a first switch is provided between the fixed power heater and the power supply; the adjustable power heater is connected to a power supply, and a power adjustment element is provided between the adjustable power heater and the power supply; the controller is connected to the first switch for controlling the on and off of the first switch; the controller is also connected to the power adjustment element for controlling the heating power of the adjustable power heater, the fixed power heater comprises a balanced power heater and a heating power heater, wherein the heat provided by the balanced power heater is equal to the sum of the heat carried away by the gas and the heat dissipated by the kiln wall, and the heat provided by the heating power heater is equal to the sum of the heat carried away by the gas, the heat dissipated by the kiln wall and the heat required for the temperature of the structural parts of the kiln body to rise to a preset first threshold value; the control method of the roller kiln comprises the following steps: when the roller kiln needs to be heated, all the first switches are controlled to be turned on, and the roller kiln is heated to a preset target temperature by using the fixed power heater and the adjustable power heater; when materials are put into the roller kiln and need to be heated, the roller kiln is heated simultaneously by using the balanced power heater and the adjustable power heater.

[0007] The roller kiln heating system provided by the present invention can control the operation of the fixed power heater by controlling the on and off of the first switch, and the controller can adjust the heating power of the adjustable power heater through the power adjustment element. Based on this, when the roller kiln needs to be heated, since more heat is required at this time, it is necessary to use a fixed power heater and an adjustable power heater to heat the roller kiln to a preset target temperature; when the roller kiln is put into the material and needs to be heated, the roller kiln needs to control the temperature more accurately, so it is necessary to use an adjustable power heater to heat the roller kiln. The roller kiln heating method provided by the present invention can not only meet the heating requirements of the roller kiln, but also use fewer power adjustment elements to reduce production costs.

[0008] In an optional embodiment, when the roller kiln needs to be heated up, the first switch is controlled to be turned on, and the roller kiln is heated to a preset target temperature using a fixed power heater and an adjustable power heater, including: when the roller kiln needs to be heated up, all the first switches are controlled to be turned on, and the roller kiln is heated using a balanced power heater, a heating power heater and an adjustable power heater; the actual temperature of the roller kiln is obtained; when the actual temperature reaches a preset first threshold value, the first switch corresponding to the heating power heater is controlled to be turned off, and the roller kiln is heated to the target temperature using a balanced power heater and an adjustable power heater.

[0009] That is to say, when the roller kiln needs to be heated, the first switch is turned on, and all heaters in the roller kiln (balanced power heater, heating power heater and adjustable power heater) are used to heat the roller kiln. When the actual temperature of the roller kiln reaches the preset first threshold, it is considered that the roller kiln is about to reach the target temperature. Since the balanced power heater and the heating power heater heat with fixed power, the heating temperature cannot be accurately controlled. Therefore, when the actual temperature of the roller kiln reaches the preset first threshold, the balanced power heater and the adjustable power heater are used to heat the roller kiln to the target temperature. It should be noted that although the balanced power heater also heats with fixed power, the roller kiln can still be accurately controlled by using the balanced power heater and the adjustable power heater to heat the roller kiln at the same time.

[0010] This is because, when the fixed power heater is divided into a balanced power heater and a heating power heater, although the balanced power heater also heats with a fixed power, the roller kiln can still be heated by using the balanced power heater and the adjustable power heater at the same time, and the temperature can still be accurately controlled. Based on this, when the roller kiln is put into the material and needs to be heated, the roller kiln can still be heated by the balanced power heater and the adjustable power heater at the same time.

[0011] In an optional embodiment, the method further includes the following steps: when the roller kiln needs to be kept warm, the roller kiln is kept warm using a balanced power heater.

[0012] This is because, since the power required by the balanced power heater to maintain the temperature of the kiln body meets the heat requirements of both the heat carried away by the gas and the heat dissipated by the kiln wall, when the roller kiln needs to be insulated, only the balanced power heater can be used to insulate the roller kiln.

[0013] In an optional embodiment, before heating the roller kiln to a preset target temperature using a fixed power heater and an adjustable power heater, the roller kiln heating method further includes the following steps: respectively obtaining the target temperature corresponding to each kiln body section in the roller kiln.

[0014] This is because, in general, a roller kiln includes multiple sections of kiln bodies, and the target temperature that needs to be reached in each section of the kiln body is different. Therefore, it is necessary to obtain the target temperature corresponding to each section of the kiln body in the roller kiln.

[0015] In a third aspect, the present invention further provides a heating device for a roller kiln, wherein at least one section of the kiln body of the roller kiln comprises a fixed power heater, an adjustable power heater and a controller, wherein the fixed power heater is connected to a power supply, and a first switch is provided between the fixed power heater and the power supply; the adjustable power heater is connected to a power supply, and a power adjustment element is provided between the adjustable power heater and the power supply; the controller is connected to the first switch for controlling the on and off of the first switch; the controller is also connected to the power adjustment element for controlling the heating power of the adjustable power heater; the fixed power heater comprises a balanced power heater and a heating power heater, wherein the balanced power heater comprises a balanced power heater and a heating power heater The heat provided by the balanced power heater is equal to the sum of the heat carried away by the gas and the heat dissipated by the kiln wall, and the heat provided by the heating power heater is equal to the sum of the heat carried away by the gas, the heat dissipated by the kiln wall and the heat required for the temperature of the structural parts of the kiln body to rise to a preset first threshold value; the control device of the roller kiln includes a preheating module and a material heating module; the preheating module is used to heat the roller kiln to a preset target temperature using a fixed power heater and an adjustable power heater when the roller kiln needs to be heated; the material heating module is used to heat the roller kiln at the same time using a balanced power heater and an adjustable power heater after the material is placed in the roller kiln.

[0016] In a fourth aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the method for heating a roller kiln according to the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0017] In a fifth aspect, the present invention provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the method for heating a roller kiln according to the first aspect or any corresponding embodiment thereof.

[0018] In a sixth aspect, the present invention provides a computer program product, comprising computer instructions for causing a computer to execute the method for heating a roller kiln according to the first aspect or any corresponding embodiment thereof.

[0019] The roller kiln heating system, roller kiln heating method, device and computer equipment provided by the present invention have the following beneficial effects: in the roller kiln heating system provided by the present invention, at least one section of the kiln body of the roller kiln includes a fixed power heater, an adjustable power heater and a controller, wherein the controller can control whether the fixed power heater works by controlling the on and off of the first switch, and the controller can adjust the heating power of the adjustable power heater through the power adjustment element, and the roller kiln is heated by the fixed power heater and the adjustable power heater to achieve various temperatures required by the roller kiln. That is to say, in the roller kiln heating system provided by the present invention, not all heaters in the roller kiln are connected to the power adjustment element, thereby reducing the number of power adjustment elements installed in the roller kiln and reducing production costs.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] According to an embodiment of the present invention, a roller kiln heating system is provided, which is applied to the roller kiln heating system, at least one section of the kiln body of the roller kiln includes a fixed power heater, an adjustable power heater and a controller, wherein the fixed power heater is connected to a power supply, and a first switch is provided between the fixed power heater and the power supply; the adjustable power heater is connected to the power supply, and a power adjustment element is provided between the adjustable power heater and the power supply; the controller is connected to the first switch, and is used to control the on and off of the first switch; the controller is also connected to the power adjustment element, and is used to control the heating power of the adjustable power heater.

[0029] In the present invention, the fixed power heater and the adjustable power heater in each kiln body can be one group or multiple groups. Each power heater can be controlled by a separate switch or multiple heaters can be controlled by one switch at the same time. The power adjustment element can be an SCR or other elements.

[0030] The roller kiln heating system provided by the present invention comprises at least one section of the kiln body of the roller kiln including a fixed power heater, an adjustable power heater and a controller, wherein the controller can control whether the fixed power heater works by controlling the on and off of a first switch, and the controller can adjust the heating power of the adjustable power heater through a power adjustment element, and the roller kiln is heated by the fixed power heater and the adjustable power heater to reach various temperatures required by the roller kiln, and the fixed power heater comprises a balanced power heater and a warming power heater, wherein the heat provided by the balanced power heater is equal to the sum of the heat carried away by the gas and the heat dissipated by the kiln wall, and the heat provided by the warming power heater is equal to the sum of the heat carried away by the gas, the heat dissipated by the kiln wall and the heat required for the temperature of the structural parts of the kiln body to rise to a preset first threshold value. That is to say, in the roller kiln heating system provided by the present invention, not all heaters in the roller kiln are connected to the power adjustment element, thereby reducing the number of power adjustment elements installed in the roller kiln and reducing production costs.

[0031] According to an embodiment of the present invention, a method for heating a roller kiln is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] In this embodiment, a roller kiln heating method is provided, which can be used in a controller of a roller kiln heating system. Figure 1 : is a flow chart of a roller kiln heating method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0033] Step S101: When the roller kiln needs to be heated, the roller kiln is heated to a preset target temperature using a fixed power heater and an adjustable power heater.

[0034] Step S102: When materials are placed in the roller kiln and need to be heated, the roller kiln is heated simultaneously by using a balanced power heater and an adjustable power heater.

[0035] The roller kiln heating system provided by the present invention can control the operation of the fixed power heater by controlling the on and off of the first switch, and the controller can adjust the heating power of the adjustable power heater through the power adjustment element. Based on this, when the roller kiln needs to be heated, since more heat is required at this time, it is necessary to use a fixed power heater and an adjustable power heater to heat the roller kiln to a preset target temperature; when materials are placed in the roller kiln and the materials need to be heated, since the roller kiln needs to control the temperature more accurately at this time, it is necessary to use an adjustable power heater to heat the roller kiln. The roller kiln heating method provided by the present invention can not only meet the heating requirements of the roller kiln, but also use fewer power adjustment elements to reduce production costs.

[0036] In this embodiment, a roller kiln heating method is provided, which can be used in a controller of a roller kiln heating system. Figure 2 : is a flow chart of another roller kiln heating method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0037] Step S201: When the roller kiln needs to be heated, the roller kiln is heated to a preset target temperature using a fixed power heater and an adjustable power heater.

[0038] In an optional embodiment, the fixed power heater includes a balanced power heater and a heating power heater; wherein the balanced power heater can provide heat from both the heat carried away by the gas and the heat dissipated by the kiln wall. The heating power heater can provide heat from the heat carried away by the gas, the heat dissipated by the kiln wall, and the heat required to raise the temperature of the structural parts of the kiln body to the target temperature.

[0039] When the roller kiln needs to be heated up, the following steps are included to heat the roller kiln to the preset target temperature using a fixed power heater and an adjustable power heater:

[0040] Step S2011: When the roller kiln needs to be heated up, all the first switches are controlled to be turned on, and the roller kiln is heated by using the fixed power heater and the adjustable power heater.

[0041] Step S2012: Obtain the actual temperature of the roller kiln.

[0042] Step S2013: When the actual temperature reaches a preset first threshold, the first switch corresponding to the heating power heater is controlled to be disconnected, and the roller kiln is heated to the target temperature by using the balanced power heater and the adjustable power heater.

[0043] It should be noted that, although an adjustable power heater is used in step S2011, in step S2011, the adjustable power heater is heated with a fixed power (e.g., the highest power). After the actual temperature of the roller kiln reaches a preset first threshold, the temperature control algorithm is started to control the adjustable power heater. Compared with the use of the temperature control algorithm to control the adjustable power heater during the entire heating process of the roller kiln, this embodiment can reduce the load rate of the computer equipment.

[0044] That is to say, when the roller kiln needs to be heated, the first switch is turned on, and all heaters in the roller kiln (balanced power heater, heating power heater and adjustable power heater) are used to heat the roller kiln. When the actual temperature of the roller kiln reaches the preset first threshold, it is considered that the roller kiln is about to reach the target temperature. Since the balanced power heater and the heating power heater heat with fixed power, the heating temperature cannot be accurately controlled. Therefore, when the actual temperature of the roller kiln reaches the preset first threshold, the balanced power heater and the adjustable power heater are used to heat the roller kiln to the target temperature. It should be noted that although the balanced power heater also heats with fixed power, the roller kiln can still be accurately controlled by using the balanced power heater and the adjustable power heater to heat the roller kiln at the same time.

[0045] Step S202: When materials are placed in the roller kiln and need to be heated, the roller kiln is heated simultaneously by using a balanced power heater and an adjustable power heater.

[0046] In this embodiment, according to the heat requirements of different kiln bodies, the heat required to be provided by the balanced power heater, heating power heater and adjustable power heater in different kiln bodies can be calculated, and the number of balanced power heaters, heating power heaters and adjustable power heaters to be set can be further calculated.

[0047] The roller kiln heating method provided by the present invention can not only heat the roller kiln accurately, but also use fewer power adjustment components, thereby reducing production costs.

[0048] In this embodiment, a roller kiln heating method is provided, which can be used in a controller of a roller kiln heating system. Figure 3 is a flow chart of another roller kiln heating method according to an embodiment of the present invention, Figure 4 is a schematic diagram of the heating process of a roller kiln according to an embodiment of the present invention, Figure 4In the figure, Pa represents the power of the adjustable power heater; Pb represents the power of the balanced power heater; ΔP represents the power of the heating power heater.

[0049] Among them, the balanced power heater can provide heat from both the heat carried away by the gas and the heat dissipated by the kiln wall. The heating power heater can provide the heat carried away by the gas, the heat dissipated by the kiln wall, and the heat required to raise the temperature of the kiln body's structural parts to the target temperature. The adjustable power heater can provide the heat carried away by the gas, the heat dissipated by the kiln wall, and the heat required to raise the temperature of the sagger to the target temperature.

[0050] like Figure 3 and Figure 4 As shown, the process includes the following steps:

[0051] Step S301: respectively obtaining the target temperature corresponding to each kiln body section in the roller kiln.

[0052] This is because, in general, a roller kiln includes multiple sections of kiln bodies, and the target temperature that needs to be reached in each section of the kiln body is different. Therefore, it is necessary to obtain the target temperature corresponding to each section of the kiln body in the roller kiln.

[0053] Step S302: When the roller kiln needs to be heated, the roller kiln is heated to a preset target temperature using a fixed power heater and an adjustable power heater.

[0054] In an optional embodiment, when the roller kiln needs to be heated, heating the roller kiln to a preset target temperature using a fixed power heater and an adjustable power heater includes the following steps:

[0055] Step S3021: When the roller kiln needs to be heated up, all the first switches are controlled to be turned on, and the roller kiln is heated by using the fixed power heater and the adjustable power heater.

[0056] Step S3022: Obtain the actual temperature of the roller kiln.

[0057] Step S3023: When the actual temperature reaches a preset first threshold, the first switch corresponding to the heating power heater is controlled to be disconnected, and the roller kiln is heated to the target temperature using the balanced power heater and the adjustable power heater.

[0058] Among them, the temperature of the roller kiln is heated to the first threshold value by using a fixed power heater and an adjustable power heater. Figure 4 The roller kiln is heated to the target temperature by using a balanced power heater and an adjustable power heater. Figure 4 The preheating temperature control stage.

[0059] Compared with the roller kiln, which can only be heated by adjustable power heaters during the heating process, such as Figure 4As shown, the adjustable power heater in this embodiment is mainly used in the preheating temperature control stage and the material temperature control stage, and less heat is required in these two stages. Therefore, the maximum power of the adjustable power heater in this embodiment can be reduced.

[0060] Step S303: When materials are put into the roller kiln and need to be heated, the roller kiln is heated by using an adjustable power heater and a balanced power heater.

[0061] Among them, after the material is put into the roller kiln and needs to be heated, the roller kiln is heated by the adjustable power heater and the balanced power heater. Figure 4 The material temperature control stage.

[0062] This is because, when the fixed power heater is divided into a balanced power heater and a heating power heater, although the balanced power heater also heats with a fixed power, the balanced power heater and the adjustable power heater are used to heat the roller kiln at the same time, and the temperature can still be accurately controlled. Based on this, when materials are placed in the roller kiln and the materials need to be heated, the balanced power heater and the adjustable power heater can still be used to heat the roller kiln at the same time.

[0063] Step S304: When the roller kiln needs to be kept warm, the roller kiln is kept warm by using a balanced power heater.

[0064] Among them, using a balanced power heater to keep the roller kiln warm is equivalent to Figure 4 In the insulation stage.

[0065] This is because, since the power required by the balanced power heater to maintain the temperature of the kiln body meets the heat requirements of both the heat carried away by the gas and the heat dissipated by the kiln wall, when the roller kiln needs to be insulated, only the balanced power heater can be used to insulate the roller kiln.

[0066] It should be noted that during the preheating and insulation stages, the power of the balanced power heater should be slightly smaller than the theoretical value, otherwise there will be a risk of overheating.

[0067] The roller kiln heating method provided by the present invention can not only heat the roller kiln accurately, but also use fewer power adjustment components, thereby reducing production costs.

[0068] In this embodiment, a heating device for a roller kiln is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and the descriptions that have been made will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function.

After the roller kiln is heated by the adjustable power heater, when the roller kiln needs to be kept warm, the heat preservation module is used to keep the roller kiln warm by using the balanced power heater.

[0075] In some optional embodiments, the heating device of the roller kiln further includes a target temperature acquisition module.
