Description

Technical Field

[0001] The invention relates to the technical field of hot blast stoves, and in particular to a hot blast stove for circulating heating with uniform temperature. Background Art

[0002] Hot air furnace is a thermal power machine with many varieties and complete series. It can be divided into manual burning and machine burning according to the coal adding method, and can be divided into coal, oil, gas furnace, etc. according to the fuel type. The working principle of the hot air furnace is to use the heat generated by the combustion of fuel to heat the low-temperature air into high-temperature air to form hot air, which is transmitted outward through pipes. It is widely used in the fields of "air drying" of electronic components, special welding processes, and drying of agricultural products. However, the flow of air in the furnace is very irregular, resulting in insufficient heating of the heat by the equipment, making the generated hot air uneven in heat, which often affects the subsequent work. When the equipment circulates the hot air, it is easy to cause water droplets to form inside the equipment, causing the water droplets to gather inside the equipment and cause damage, thereby shortening the service life of the equipment. It is not easy for the hot air to circulate when it circulates inside the equipment, making it difficult for the equipment to control the hot air generated by heating, affecting the stability inside the equipment, and increasing the difficulty of evenly circulating the hot air in the equipment.

[0003] To sum up, the flow of air in the furnace is very irregular, which leads to insufficient heating of the equipment and uneven heat of the generated hot air, which often affects the subsequent work. The hot air is not easy to circulate when it circulates inside the equipment, which increases the difficulty of uniform hot air circulation in the equipment. Summary of the invention

[0024] The present invention provides a hot air furnace for circulating heating with uniform temperature. It has the following beneficial effects:

[0025] The hot air furnace for circulating heating with uniform temperature is provided with a circulating pipe, an air supply box and a temperature control component. When the air supply box works on the furnace body, the external wind is transported to the inside of the furnace body, so that the wind circulates from bottom to top, which is convenient for the heat to be evenly distributed inside the furnace body, thereby avoiding the uneven temperature inside the furnace body. The circulating pipe is close to the air supply box inside the furnace body, so that the circulating pipe can circulate the hot air heated by the pretreatment component, which is convenient for the circulating pipe to evenly transfer the heat. The heat generated by the temperature control component circulates from top to bottom into the furnace body for heating treatment, so that the heat circulated by the temperature control component can contact the hot air discharged by the circulating pipe, thereby ensuring the sealing of the furnace body during heating treatment.

[0026] The hot air furnace for circulating heating with uniform temperature is connected to the circulation pipe through the installation box on the outer surface of the furnace body, so that the installation box can pre-treat the air inside when it circulates, so that the conveying tube can work to control the rate of air circulation in the installation box, so that the installation box can protect the conveying tube on the furnace body, and the partition shell can separate the conveying tube and the preheater inside the installation box, so that the partition shell can separate the space inside the installation box and guide the circulation of air at the same time, so that the air can circulate through the partition shell to a position close to the preheater.

[0027] The hot air furnace for circulating heating with uniform temperature preheats the air inside the installation box through the preheater, which facilitates the circulation of the air after the preheater preheats it, and can process part of the moisture in the air inside the installation box, thus avoiding the accumulation of water flow inside the furnace body and affecting its use. The expansion plate expands on the limiting plate due to the heat, so that the expansion of the expansion plate pushes the sealing plate to move along the installation box, and the position of the sealing plate is adjusted along with the expansion length of the expansion plate, so that the movement of the sealing plate is convenient for adjusting the flow rate of the hot air.

[0028] The hot air furnace for circulating heating with uniform temperature is evenly distributed inside the partition shell through the side support plates, so that part of the air entering the partition shell enters the spoiler tube, and the other part is discharged from the partition shell, so that the spoiler tube and the side support plates cooperate to divert the air circulation, and prevent the partition shell from being damaged inside the installation box and affecting the air circulation. The middle fixed rod penetrates the spoiler tube and contacts the partition shell, so that the middle fixed rod and the side support plates cooperate to fix the partition shell, and the displacement of the spoiler tube inside the partition shell is avoided.

[0029] The hot air furnace for circulating heating with uniform temperature has movable rods distributed in a circular shape on the middle fixed rod, so that the movable rods swing inside the spoiler tube to disturb the circulation of air, and the movable rods are knocked by contact during the swinging process, so that dust can be dropped by vibration generated when the movable rods knock. The docking plate cooperates with the movable rod on the middle fixed rod, so that the docking plate can contact the movable rod, so that the docking plate can limit the swing of the movable rod and ensure the swing of the movable rod inside the spoiler tube.

[0030] The hot air furnace for circulating heating with uniform temperature generates heat through the heating tube working inside the guide shell, which facilitates the heat to flow from top to bottom to the hot air discharged from the circulation pipe, ensuring the distribution of heat inside the furnace body, and the connecting plate can cooperate with the intercepting plate to make the intercepting plate divert the heat discharged from the guide shell, and the intercepting plate can be used to protect the heating tube, avoiding damage to the heating tube and affecting heating, and facilitating the connection plate and the intercepting plate to connect the guide shells at different positions for protection.

[0031] The hot air furnace for circulating heating with uniform temperature has a protective tube that penetrates the furnace body on the guide shell, so that the protective tube can reinforce the guide shell, so that the heat inside the protective tube is not easily lost, and the sealing inside the furnace body is maintained. The lifting ring frame is driven by the shielding cover to rise and fall inside the protective tube, so that the lifting ring frame moves along the protective tube to support the shielding cover, which is convenient for maintaining the stability of the shielding cover during movement and avoiding the lifting ring frame from getting stuck during movement and affecting the shielding cover.

[0032] The hot air furnace for circulating heating with uniform temperature is installed inside the furnace body through an auxiliary box, which is convenient for the auxiliary box to maintain internal movable space under the support of the support frame, and prevents the auxiliary box from deforming inside the furnace body and causing changes in the installation position. Two clamping plates are arranged on the auxiliary box, so that the two clamping plates cooperate with each other to fix the radiator, which is convenient for the radiator to work at a position close to the inlet of the auxiliary box. The radiator fixed by the clamping plates can dissipate heat inside the furnace body when working.

[0033] The hot air furnace for circulating heating with uniform temperature guides heat to the radiator through the heat exchange tube when the radiator is performing heat dissipation work, so that the heat dissipation port on the auxiliary box can discharge the heat. The telescopic rod contracts on the radiator to drive the movable plate to move toward the radiator, so that the movable plate is separated from the auxiliary box to expose the heat dissipation port, so that the heat inside the auxiliary box can be discharged through the heat dissipation port, thus avoiding the heat dissipation of the auxiliary box affecting the heat inside the furnace body when the furnace body is working, and facilitating the movable plate and the telescopic rod to cooperate to support the radiator.

[0034] The hot air furnace for circulating heating with uniform temperature is horizontally installed on the auxiliary box through a support frame to prevent the middle solid block from being displaced on the support frame and affecting its use, so that the support frame and the middle solid block can cooperate to separate the activity space inside the auxiliary box. The swing plate is pushed by wind force to swing on the arc plate, so that the swing plate drives the linkage block to move when it swings, so that the swing plate can adjust the linkage block and prevent the movement of the swing plate from being affected, thereby increasing the strength of the arc plate itself.

The heating cylinder 36 generates heat when working inside the guide shell 31, so that the guide shell 31 guides the heat, which is convenient for the heat to flow from top to bottom to the hot air discharged by the circulation pipe 5, so that the heat generated by the heating cylinder 36 cooperates with the circulation pipe 5 for heating treatment, which is convenient for maintaining rapid heating inside the furnace body 1 and maintaining uniform circulation of hot air during the heating process, ensuring the distribution of heat inside the furnace body 1, and three heating cylinders 36 are arranged inside the guide shell 31, so that the heating cylinders 36 can support the guide shell 31, thereby ensuring the bearing capacity of the guide shell 31 itself, and the bottom of the inner cavity of the guide shell 31 is fixedly connected with an interception plate 34;

[0061] The protective tube 32 is connected to the top of the guide shell 31, and penetrates the furnace body 1 through the protective tube 32 on the guide shell 31, so that the protective tube 32 can transfer the heat inside the heating tube 36, which is convenient for the protective tube 32 to reinforce the guide shell 31. When the protective tube 32 is connected to the shielding cover 33, it can be sealed, so that the heat inside the protective tube 32 is not easy to be lost, which is convenient for maintaining the sealing inside the furnace body 1. When the protective tube 32 is separated from the shielding cover 33, the protective tube 32 and the shielding cover 33 generate a movable space, so that the protective tube 32 can discharge the internal heat, which is convenient for the protective tube 32 to accelerate the heat dissipation of the furnace body 1. The protective tube 32 The inner surface of the lifting ring frame 35 is slidably connected to the lifting ring frame 35, and the lifting ring frame 35 is driven by the shielding cover 33 to lift and lower inside the protective tube 32, so that the lifting ring frame 35 can support the shielding cover 33 when moving along the protective tube 32, so as to maintain the stability of the shielding cover 33 during movement, and the lifting ring frame 35 is connected to the shielding cover 33 to be positioned, so that the lifting ring frame 35 is not easily displaced on the shielding cover 33, ensuring that the lifting ring frame 35 can perform vertical lifting and lowering movements inside the protective tube 32, avoiding the lifting ring frame 35 from getting stuck during movement and affecting the shielding cover 33, and the top of the lifting ring frame 35 is fixedly connected to the shielding cover 33.

[0063] The auxiliary assembly 4 includes an auxiliary box 41, which is connected to the inner surface of the furnace body 1 and is installed inside the furnace body 1 through the auxiliary box 41, so that the auxiliary box 41 can protect the internal installed components, and the installation position of the auxiliary box 41 corresponds to the temperature sensor 8, which is convenient for the auxiliary box 41 to maintain the internal activity space under the support of the support frame 47, and prevent the auxiliary box 41 from deforming inside the furnace body 1 and causing the installation position to change, which is convenient for the auxiliary box 41 to circulate heat and transfer heat. The inner surface is fixedly connected with a support frame 47, and a clamping plate 42 is fixedly connected to the auxiliary box 41 at a position away from the support frame 47. Two clamping plates 42 are arranged on the auxiliary box 41, so that the two clamping plates 42 cooperate with each other to fix the radiator 44, thereby ensuring the stability of the radiator 44 inside the auxiliary box 41, and facilitating the radiator 44 to work at a position close to the inlet of the auxiliary box 41. When the radiator 44 fixed by the clamping plate 42 is working, it can dissipate heat inside the furnace body 1, which is convenient for heating the heat loss inside the furnace body 1, thereby achieving the effect of rapid cooling of the furnace body 1;

[0064] The radiator 44 is fixedly connected to the side of the clamping plate 42 away from the auxiliary box 41. The radiator 44 is used to dissipate heat inside the furnace body 1. The outer surface of the radiator 44 is fixedly connected with a heat exchange tube 43. The heat is guided to transfer to the radiator 44 through the heat exchange tube 43 when the radiator 44 performs heat dissipation work, so that the radiator 44 works in the wind force inside the auxiliary box 41, so that the wind force generated by the radiator 44 transports the heat, which is convenient for the heat dissipation port on the auxiliary box 41 to discharge the heat. The heat exchange tube 43 on the radiator 44 can protect the radiator 44, ensure that the heat exchange tube 43 and the radiator 44 work together, thereby accelerating the heat inside the furnace body 1 to flow into the auxiliary box 41. A telescopic rod 45 is fixedly connected to the side away from the heat exchange tube 43. The telescopic rod 45 contracts on the radiator 44 to drive the movable plate 46 to move toward the radiator 44, so that the movable plate 46 is separated from the auxiliary box 41 to expose the heat dissipation port, so that the heat inside the auxiliary box 41 can be discharged through the heat dissipation port. When the radiator 44 stops working, the telescopic rod 45 extends to push the movable plate 46 to contact the auxiliary box 41 again, so that the movable plate 46 seals the heat dissipation port of the auxiliary box 41, so that the heat dissipation of the auxiliary box 41 when the furnace body 1 is working is avoided, and the movable plate 46 cooperates with the telescopic rod 45 to support the radiator 44. The end of the telescopic rod 45 away from the radiator 44 is fixedly connected to the movable plate 46.

[0065] The side of the movable plate 46 away from the telescopic rod 45 is slidably connected to the auxiliary box 41 , and the outer surface of the heat exchange tube 43 extends to the outside of the auxiliary box 41 .

[0066] The outer surface of the support frame 47 is fixedly connected with a middle solid block 48, and the support frame 47 is horizontally installed on the auxiliary box 41, so that the support frame 47 fixes the middle solid block 48 to prevent the middle solid block 48 from being displaced on the support frame 47 and affecting the use. The position where the support frame 47 is connected to the auxiliary box 41 can be used to reinforce the auxiliary box 41, so that the support frame 47 and the middle solid block 48 can cooperate to separate the activity space inside the auxiliary box 41, so that the support frame 47 can divert the heat inside the auxiliary box 41 when it circulates. The outer surface of the middle solid block 48 is fixedly connected with a stabilizing plate 4 12, the arc plate 49 is fixed on the middle solid block 48 by the stabilizing plate 412, so that the arc plate 49 and the support frame 47 are kept horizontal, so that the arc plate 49 and the support frame 47 cooperate to perform the diversion work, and the stabilizing plate 412 can limit the installation position of the arc plate 49 on the middle solid block 48, so that the connection position of the arc plate 49 and the stabilizing plate 412 is not easy to loosen, ensuring that the stabilizing plate 412 cooperates with the support frame 47 and the arc plate 49 to increase the contact area inside the auxiliary box 41, and the stabilizing plate 412 is fixedly connected with the arc plate 49 at a position away from the middle solid block 48;

[0067] The swing plate 410 is fixedly connected to the outer surface of the arc plate 49. The swing plate 410 is pushed by the wind to swing on the arc plate 49, so that the swing plate 410 drives the linkage block 411 to move when it swings, so that the swing plate 410 can adjust the linkage block 411 to prevent the movement of the swing plate 410 from being affected. The movement of the swing plate 410 and the linkage block 411 can limit the arc plate 49, avoiding the bending or breaking of the position where the arc plate 49 is connected to the swing plate 410, thereby increasing the strength of the arc plate 49 itself. The swing plate 410 is fixedly connected with the linkage block 411 at a position away from the arc plate 49.

[0068] Example 2, please refer to Figure 1-Figure 12 , based on Example 1, the present invention provides a technical solution: a method for using a hot air furnace for circulating heating with uniform temperature, step 1: the conveying cylinder 27 works inside the installation box 21 to convey the outside air to the inside of the installation box 21, the air flows to the partition shell 26 inside the installation box 21, the middle fixing rod 210 and the side support plate 29 support the spoiler cylinder 28 inside the partition shell 26, so that part of the air inside the partition shell 26 enters the spoiler cylinder 28, and the other part is directly discharged from the partition shell 26, and the air entering the spoiler cylinder 28 circulates, and the movable rod 211 is driven to swing when the movable rod 211 swings and contacts the docking plate 212 and rotates in the opposite direction, so that the swing of the movable rod 211 disturbs the air, and the air after disturbance is discharged from the spoiler cylinder 28, and then discharged from the partition shell 26;

[0069] Step 2: Use the preheater 24 to preheat the air discharged from the partition shell 26 inside the installation box 21. When the preheater 24 generates heat and circulates inside the installation box 21, the expansion plate 25 is expanded by the heat on the limiting plate 22, so that the expansion plate 25 expands and pushes the sealing plate 23 to slide on the installation box 21 to reveal the opening for the preheated air to enter the circulation pipe 5. As the expansion plate 25 expands, the moving distance of the sealing plate 23 is adjusted. When the temperature inside the installation box 21 drops, the expansion plate 25 contracts and drives the sealing plate 23 to re-seal the opening, so that the sealing plate 23 moves to adjust the flow rate of the air entering the circulation pipe 5.

[0070] Step 3: Circulate the preheated air through the circulation pipe 5 so that the air can re-enter the installation box 21 through the circulation pipe 5. The fixing plate 7 fixes the circulation pipe 5 inside the furnace body 1, and the fixing plate 7 is located on the side away from the installation box 21. As the circulation pipe 5 discharges air, the air supply box 6 works at the bottom of the furnace body 1 to transport the air, so that the wind contacts the hot air and drives the hot air to circulate inside the furnace body 1. The temperature sensor 8 senses the circulating heat in real time inside the furnace body 1, so that the heat inside the furnace body 1 is kept at a constant position.

[0071] Step 4: Fix the heating tube 36 inside the guide shell 31 through the connecting plate 37, so that the heating tube 36 works when the temperature inside the furnace body 1 does not reach the set value, so that the heating tube 36 works to heat the inside of the furnace body 1, and the heat generated by the heating tube 36 circulates through the guide shell 31, so that the heat circulates from top to bottom along the guide shell 31, and the intercepting plate 34 diverts the circulating heat on the guide shell 31, so that the heat circulating inside the guide shell 31 is mixed with the hot air circulating in the circulation pipe 5 for secondary heating, and the shielding cover 33 seals the protective tube 32 when it contacts the protective tube 32, so that the heat inside the guide shell 31 is not easy to leak, and the shielding cover 33 is prevented from being pulled upward to drive the lifting ring frame 35 to move, so that the lifting ring frame 35 can generate activity space when sliding along the inner wall of the protective tube 32, so that the heat inside the guide shell 31 can be discharged;

[0072] Step 5: The auxiliary box 41 corresponds to the temperature sensor 8 inside the furnace body 1, so that when the furnace body 1 performs heat dissipation work, the radiator 44 works inside the auxiliary box 41 to move the heat, and the heat exchange tube 43 on the radiator 44 guides the heat inside the furnace body 1 to the radiator 44, so that the radiator 44 works to generate wind force to transport the moving plate 46, and the telescopic rod 45 contracts when performing heat dissipation work to drive the moving plate 46 to approach the radiator 44, so that a heat dissipation port is generated on the auxiliary box 41 for heat dissipation;

[0073] Step six: Use the clamping plate 42 to fix the radiator 44 on the auxiliary box 41. After the heat dissipation is completed, the telescopic rod 45 extends to push the movable plate 46 to contact the auxiliary box 41 again, so that the movable plate 46 seals the auxiliary box 41, and the support frame 47 fixes the middle solid block 48, so that the middle solid block 48 fixes the arc plate 49 through the stabilizing plate 412, so that the arc plate 49 and the support frame 47 are installed horizontally. As the wind flows inside the auxiliary box 41, the swing plate 410 is pushed by the wind to drive the linkage block 411 to swing, and the swing plate 410 stops moving when it loses the wind force.
