Description

Technical Field

[0001] The present invention relates to the technical field of raw material preheating and mixing, and specifically to a low-energy consumption preheating device for chemical raw materials of a chemical furnace. Background Technique

[0002] A low-energy consumption preheating device for chemical raw materials of a chemical furnace usually consists of parts such as a mixing furnace, an exhaust gas box, preheating pipes, and a driving device.

[0003] The patent with the patent announcement number CN219494859U relates to a preheating device for low-energy consumption comprehensive treatment of clinker burning. Its technical solution includes: a base, a partition board, and a housing. The top surface of the base is welded with a fixing frame and a housing. The top inner wall surface of the housing is fitted with a ceramic heating tube, and a fixing tube is fixedly embedded in the top surface of the housing. A fan is installed in the fixing tube, and an air inlet pipe is fixedly embedded in the fixing tube. A panel is welded inside the housing, and a conveyor belt is arranged inside the panel. The top surface of the partition board is fitted with a first coiled pipe. The rear end surface of the housing is fixed with a water tank, and a water pump is installed on the bottom inner wall surface of the water tank.

[0004] In the above patent, it meets the material preheating, can process and produce quickly, and is convenient for recycling and utilization of the heat in production and processing. However, it is difficult to increase the contact area and mixing efficiency between the reaction gas and the chemical raw materials. Due to the low contact area and mixing efficiency, there will be a large loss of the thermal energy of the reaction gas during the transfer process, so it takes longer time and more reaction gas to achieve the predetermined preheating effect. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a low-energy consumption preheating device for chemical raw materials of a chemical furnace, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A low-energy consumption preheating device for chemical raw materials of a chemical furnace, comprising: a mixing furnace, which is arranged on the top of the ground and is used for stirring and mixing chemical raw materials; an exhaust gas box, which is arranged on the top of the mixing furnace and is used for preheating chemical raw materials; a discharge pipe, which is fixedly installed at the rear side of the exhaust gas box; a connecting pipe one, which is fixedly installed on the left side of the exhaust gas box; a connecting pipe two, which is fixedly installed on the left side of the mixing furnace; a preheating pipe, one end of which is slidably installed on the inner wall of the connecting pipe one, and the other end of which is slidably installed on the inner wall of the connecting pipe two; a valve, which is arranged on the circumferential surface of the preheating pipe; a servo motor, which is fixedly installed on the left side of the exhaust gas box; a lead screw, which is fixedly installed at the output end of the servo motor; a mixing frame, which is slidably installed on the inner wall of the exhaust gas box and is threadedly connected with the lead screw. The mixing frame moves back and forth to stir the chemical raw materials inside the exhaust gas box, thereby increasing the contact area and mixing efficiency between the reaction gas and the chemical raw materials.

[0007] According to the above technical solution, a rotating rod penetrates through the bottom of the exhaust gas box, a feeding plate is fixedly installed on the circumferential surface of the rotating rod, a feeding hole is opened on the top of the feeding plate, a groove block is fixedly installed on the circumferential surface of the rotating rod, a rack is fixedly installed on the top inner wall of the mixing frame, and a blanking hole is opened on the bottom of the exhaust gas box. The rotation and reset of the rotating rod drive the rotation and reset of the feeding plate, and the rotation and reset of the feeding plate block the blanking hole.

[0008] According to the above technical solution, a torsion spring is arranged between the rotating rod and the exhaust gas box. When the rotating rod rotates, it squeezes the torsion spring. The torsion spring deforms and stores energy under the extrusion of the rotating rod. After the groove block disengages from the contact with the rack, the rotating rod can be driven to reset by the torsion spring. The feeding plate abuts against the bottom of the exhaust gas box. The bottom of the mixing frame is set as an inclined surface, and granular chemical raw materials are arranged inside the exhaust gas box.

[0009] According to the above technical solution, a guiding component for preventing excessive preheating of chemical raw materials is arranged on the inner wall of the exhaust gas box, and a protection component is arranged on the inner wall of the connecting pipe one. The guiding component includes a perforated plate, a square plate, a heat insulation plate, a diversion pipe and a heat insulation rod. The movement and reset of the heat insulation plate drive the movement and reset of the diversion pipe. The reciprocating movement of the diversion pipe guides the reaction gas entering the inside of the exhaust gas box. The perforated plate is fixedly installed on the inner wall of the exhaust gas box. The heat insulation rod slidably penetrates through the left and right walls of the perforated plate. The square plate is fixedly installed on the left side of the heat insulation rod. The heat insulation plate is fixedly installed on the right side of the heat insulation rod. The diversion pipe is fixedly installed on the right side of the heat insulation plate.

[0010] According to the above technical solution, the right side of the heat insulation plate is set as an arc surface. The heat insulation plate abuts against the inner wall of the exhaust gas box. A return spring is arranged between the porous plate and the square plate. The square plate moves towards the preheating pipe to pull the return spring. The return spring deforms and stores energy under the pull of the square plate. When the heat insulation plate moves back to its original position, the return spring can drive the heat insulation plate to vibrate. The vibration of the heat insulation plate drives the vibration of the diversion pipe. The vibration of the heat insulation plate and the diversion pipe helps to disturb the static air flow.

[0011] According to the above technical solution, the protection component includes a connecting rod, a connecting plate, a connecting groove and a connecting spring. The preheating pipe is restricted from horizontal movement by the connecting plate. The connecting rod is fixedly installed on the inner wall of the connecting pipe one. The connecting plate is slidably installed on the circumferential surface of the connecting rod. The connecting groove is opened on the inner wall of the preheating pipe. The connecting spring is arranged between the connecting rod and the connecting plate.

[0012] According to the above technical solution, a strip-shaped rod is fixedly installed at the bottom of the exhaust gas box. The strip-shaped rod is elastic. A protection rod is fixedly installed on the right side of the valve. When the connecting plate moves upward to pull the connecting spring, the connecting spring deforms and stores energy under the pull of the connecting plate. After the connecting plate disengages from the contact with the square plate, the connecting spring can drive the connecting plate to return to its original position.

[0013] According to the above technical solution, the protection rod contacts the strip-shaped rod. The bottom of the connecting plate is set as an inclined surface. The strip-shaped rod gradually deforms to make the protection rod slowly move to the left. The slow movement of the protection rod to the left provides anti-impact protection for the preheating pipe. The connecting plate contacts the square plate.

[0014] The present invention provides a low-energy consumption preheating device for chemical raw materials of a chemical furnace. It has the following beneficial effects:

[0015] (1) For the low-energy consumption preheating device for chemical raw materials of this chemical furnace, the mixing rack moves back and forth to stir the chemical raw materials inside the exhaust gas box, thereby increasing the contact area and mixing efficiency between the reaction gas and the chemical raw materials. Through the reciprocating movement of the mixing rack, the chemical raw materials inside the exhaust gas box can be effectively stirred, promoting the full contact and mixing between the reaction gas and the raw materials, thereby improving the preheating efficiency of the chemical raw materials and shortening the time required for preheating the chemical raw materials. The chemical raw materials inside the exhaust gas box are intermittently put into the mixing furnace by intermittently aligning the feeding hole and the discharging hole. Intermittent feeding helps to control the time and temperature during the preheating process, thereby improving the preheating efficiency of the chemical raw materials.

[0016] (2) For the low-energy consumption preheating device for chemical raw materials of this chemical furnace, the diversion pipe moves back and forth to guide the reaction gas entering the exhaust gas box. The reciprocating movement of the diversion pipe makes the reaction gas flow more evenly, avoiding the phenomenon of too high or too low local temperature of the chemical raw materials, and making the preheating process more uniform.

[0017] (3) The low - energy - consumption pre - heating device for chemical raw materials of this chemical furnace can help disturb the airflow in the dead zone through the shaking of the heat - insulating plate and the diversion pipe, thus promoting the uniform distribution of the reaction gas. By shaking the heat - insulating plate and the diversion pipe, the contact area between the gas and the raw materials can be increased, thereby further improving the heat transfer efficiency of the reaction gas.

[0018] (4) The low - energy - consumption pre - heating device for chemical raw materials of this chemical furnace limits the pre - heating pipe by the upward movement of the connecting plate to contact the inner wall of the connecting groove. At the beginning of pre - heating, the pre - heating pipe usually faces expansion or contraction caused by temperature changes. Limiting the pre - heating pipe can fix its position, avoid gas leakage caused by temperature changes in the initial stage of pre - heating, and further optimize the heat - exchange process.

[0019] (5) The low - energy - consumption pre - heating device for chemical raw materials of this chemical furnace makes the protective rod slowly move to the left as the strip - shaped rod gradually deforms. The slow left - ward movement of the protective rod protects the pre - heating pipe from impact. Through the slow displacement, the protective rod can gradually absorb and disperse the impact force, thus avoiding the deformation of the pre - heating pipe caused by the violent impact due to the overly violent reaction of the chemical raw materials.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , an embodiment of the present invention is: a low-energy consumption preheating device for chemical raw materials of a chemical furnace, including: a mixing furnace 1, the mixing furnace 1 is arranged on the top of the ground, and the mixing furnace 1 is used for stirring and mixing chemical raw materials; an exhaust gas box 2, the exhaust gas box 2 is arranged on the top of the mixing furnace 1, and the exhaust gas box 2 is used for preheating chemical raw materials; a discharge pipe 3, the discharge pipe 3 is fixedly installed at the rear side of the exhaust gas box 2; a connecting pipe 4, the connecting pipe 4 is fixedly installed on the left side of the exhaust gas box 2; a connecting pipe 5, the connecting pipe 5 is fixedly installed on the left side of the mixing furnace 1; a preheating pipe 6, one end of the preheating pipe 6 is slidably installed on the inner wall of the connecting pipe 4, and the other end of the preheating pipe 6 is slidably installed on the inner wall of the connecting pipe 5; a valve 7, the valve 7 is arranged on the circumferential surface of the preheating pipe 6; a servo motor 8, the servo motor 8 is fixedly installed on the left side of the exhaust gas box 2; a lead screw 9, the lead screw 9 is fixedly installed at the output end of the servo motor 8; a mixing frame 10, the mixing frame 10 is slidably installed on the inner wall of the exhaust gas box 2, and the mixing frame 10 is threadedly connected with the lead screw 9. Through the reciprocating movement of the mixing frame 10, the chemical raw materials inside the exhaust gas box 2 can be effectively stirred, promoting the full contact and mixing between the reaction gas and the raw materials, thereby improving the preheating efficiency of the chemical raw materials.

[0024] A rotating rod 11 rotatably penetrates through the bottom of the exhaust gas box 2. A feeding plate 12 is fixedly installed on the circumferential surface of the rotating rod 11. A feeding hole 13 is opened at the top of the feeding plate 12. A groove block 14 is fixedly installed on the circumferential surface of the rotating rod 11. A rack 15 is fixedly installed on the top inner wall of the mixing frame 10. A blanking hole 16 is opened at the bottom of the exhaust gas box 2. The rotation and reset of the rotating rod 11 drive the rotation and reset of the feeding plate 12. The rotation and reset of the feeding plate 12 cover the blanking hole 16. By intermittent feeding, it is helpful to control the time and temperature during the preheating process, thereby improving the preheating efficiency of the chemical raw materials.

[0025] A torsion spring is arranged between the rotating rod 11 and the exhaust gas box 2. The rotation of the rotating rod 11 squeezes the torsion spring. The torsion spring deforms and stores energy under the extrusion of the rotating rod 11. After the groove block 14 is separated from the contact with the rack 15, the rotating rod 11 can be driven to reset by the torsion spring. The feeding plate 12 abuts against the bottom of the exhaust gas box 2. The bottom of the mixing frame 10 is set as an inclined surface. Granular chemical raw materials are arranged inside the exhaust gas box 2.

[0026] During the operation of this embodiment: The chemical raw materials to be preheated are put into the waste gas box 2 through the feeding pipe 3. At the same time, the valve 7 is started so that the reaction gas in the mixing furnace 1 enters the waste gas box 2 through the connecting pipe II 5, the preheating pipe 6 and the connecting pipe I 4. The reaction gas entering the waste gas box 2 preheats the chemical raw materials in the waste gas box 2. At the same time, the servo motor 8 is started to drive the screw rod 9 to rotate. The rotation of the screw rod 9 drives the mixing frame 10 to move to the left. After the mixing frame 10 moves to the left to the designated position, the servo motor 8 operates to drive the screw rod 9 to rotate in the reverse direction. The reverse rotation of the screw rod 9 drives the mixing frame 10 to move to the right and reset. The reciprocating movement of the mixing frame 10 stirs the chemical raw materials in the waste gas box 2, thereby increasing the contact area and mixing efficiency between the reaction gas and the chemical raw materials. And the contact area between the reaction gas and the chemical raw materials is increased, thereby improving the preheating efficiency of the chemical raw materials. The movement of the mixing frame 10 to the left drives the rack 15 to move to the left. The movement of the rack 15 to the left contacts the groove block 14 and squeezes the groove block 14. The groove block 14 rotates under the extrusion of the rack 15. The rotation of the groove block 14 drives the rotating rod 11 to rotate. The rotation of the rotating rod 11 drives the feeding plate 12 to rotate. The rotation of the feeding plate 12 aligns the feeding hole 13 with the blanking hole 16. After the mixing frame 10 moves to the right and resets, the movement of the mixing frame 10 to the right drives the rack 15 to move to the right and reset. The movement of the rack 15 to the right and reset disengages from the contact with the groove block 14. After the groove block 14 disengages from the contact with the rack 15, the rotating rod 11 rotates in the reverse direction and resets under the elastic force of the torsion spring. The rotation of the rotating rod 11 to reset drives the feeding plate 12 to rotate and reset. The rotation of the feeding plate 12 to reset blocks the blanking hole 16. The intermittent alignment of the feeding hole 13 and the blanking hole 16 intermittently feeds the chemical raw materials in the waste gas box 2 into the mixing furnace 1.

[0027] Please refer to Figures 1-7 , on the basis of the above embodiment, in another embodiment of the present invention, a guiding component for preventing the over-preheating of chemical raw materials is provided on the inner wall of the waste gas box 2, and a protection component is provided on the inner wall of the connecting pipe I 4. The guiding component includes a perforated plate 171, a square plate 172, a heat insulation plate 173, a diversion pipe 174 and a heat insulation rod 175. The perforated plate 171 is fixedly installed on the inner wall of the waste gas box 2. The heat insulation rod 175 slidably penetrates the left and right walls of the perforated plate 171. The square plate 172 is fixedly installed on the left side of the heat insulation rod 175. The heat insulation plate 173 is fixedly installed on the right side of the heat insulation rod 175. The diversion pipe 174 is fixedly installed on the right side of the heat insulation plate 173. The reciprocating movement of the diversion pipe 174 makes the reaction gas flow more evenly, avoiding the phenomenon that the local temperature of the chemical raw materials is too high or too low, and making the preheating process more uniform.

[0028] The right side of the heat insulation plate 173 is set as an arc surface. The heat insulation plate 173 abuts against the inner wall of the exhaust gas box 2. A return spring 176 is arranged between the porous plate 171 and the square plate 172. The square plate 172 moves towards the preheating pipe 6 to pull the return spring 176. The return spring 176 deforms and stores energy under the pull of the square plate 172. When the heat insulation plate 173 moves back to its original position, the return spring 176 can drive the heat insulation plate 173 to vibrate. The vibration of the heat insulation plate 173 drives the vibration of the diversion pipe 174. The vibration of the heat insulation plate 173 and the diversion pipe 174 helps to disturb the static airflow. Through the vibration of the heat insulation plate 173 and the diversion pipe 174, the dead zone airflow can be disturbed, thereby further improving the heat transfer efficiency of the reaction gas.

[0029] The protection component includes a connecting rod 181, a connecting plate 182, a connecting groove 183 and a connecting spring 186. The connecting rod 181 is fixedly installed on the inner wall of the first connecting pipe 4. The connecting plate 182 is slidably installed on the circumferential surface of the connecting rod 181. The connecting groove 183 is opened on the inner wall of the preheating pipe 6. The connecting spring 186 is arranged between the connecting rod 181 and the connecting plate 182. By limiting the preheating pipe 6, its position can be fixed to avoid gas leakage caused by temperature changes during the initial preheating stage, and further optimize the heat exchange process.

[0030] A strip-shaped rod 185 is fixedly installed at the bottom of the exhaust gas box 2. The strip-shaped rod 185 is elastic. A protection rod 184 is fixedly installed on the right side of the valve 7. The connecting plate 182 moves upward to pull the connecting spring 186. The connecting spring 186 deforms and stores energy under the pull of the connecting plate 182. After the connecting plate 182 disengages from the contact with the square plate 172, the connecting spring 186 can drive the connecting plate 182 to reset.

[0031] The protection rod 184 contacts the strip-shaped rod 185. The bottom of the connecting plate 182 is set as an inclined surface. The strip-shaped rod 185 gradually deforms, causing the protection rod 184 to slowly move to the left. The slow movement of the protection rod 184 provides anti-impact protection for the preheating pipe 6. Through the slow displacement, the protection rod 184 can gradually absorb and disperse the impact force, thereby avoiding deformation of the preheating pipe 6 caused by too violent reaction of chemical raw materials. Then the connecting plate 182 contacts the square plate 172.

[0032] During the operation of this embodiment: The rack 15 moves to the left to contact the heat insulation plate 173 and extrude the heat insulation plate 173. The heat insulation plate 173 moves to the left under the extrusion of the rack 15. The heat insulation plate 173 moves to the left to drive the heat insulation rod 175 to move to the left. The heat insulation rod 175 moves to the left to drive the square plate 172 to move towards the preheating pipe 6. When the rack 15 moves to the right to reset, the rack 15 moves to the right to reset and disengages from the contact with the heat insulation plate 173. After the heat insulation plate 173 disengages from the contact with the rack 15, the square plate 172 moves to the right to reset under the elastic force of the reset spring 176, away from the preheating pipe 6. The square plate 172 moves to the right to reset and drives the heat insulation rod 175 to move back to its original position. The heat insulation rod 175 moves back to its original position to drive the heat insulation plate 173 to move back to its original position. The heat insulation plate 173 moves back to its original position to drive the diversion pipe 174 to move back to its original position. The reciprocating movement of the diversion pipe 174 diverts the reaction gas entering the waste gas box 2. The reaction gas entering the waste gas box 2 is evenly distributed inside the waste gas box 2 under the diversion of the diversion pipe 174. The reaction gas entering the waste gas box 2 is evenly distributed inside the waste gas box 2 to evenly preheat the chemical raw materials. At the same time, when the heat insulation plate 173 moves back to its original position, the heat insulation plate 173 vibrates under the elastic force of the reset spring 176. The vibration of the heat insulation plate 173 drives the diversion pipe 174 to vibrate. The vibration of the heat insulation plate 173 and the diversion pipe 174 helps to disturb the static airflow, thereby promoting the uniform distribution of the reaction gas.

[0033] The square plate 172 moves towards the preheating pipe 6 and contacts the inclined surface at the bottom of the connecting plate 182 and extrudes the bottom of the connecting plate 182. The connecting plate 182 moves upward under the extrusion of the square plate 172. The connecting plate 182 moves upward to contact the inner wall of the connecting groove 183 and limit the preheating pipe 6. The preheating pipe 6 cannot move horizontally under the limitation of the connecting plate 182. When the square plate 172 moves away from the preheating pipe 6, the square plate 172 moves away from the preheating pipe 6 and disengages from the contact with the connecting plate 182. After the connecting plate 182 disengages from the contact with the square plate 172, the connecting plate 182 moves downward to reset under the elastic force of the connecting spring 186. The connecting plate 182 moves downward to reset and disengages from the contact with the connecting groove 183 and releases the contact with the preheating pipe 6. At the same time, if the preheating pipe 6 horizontally displaces under the impact of the reaction gas, the preheating pipe 6 moves horizontally to the left to drive the protection rod 184 to move. The protection rod 184 moves to extrude the strip-shaped rod 185. The strip-shaped rod 185 gradually deforms under the extrusion of the protection rod 184. The gradual deformation of the strip-shaped rod 185 causes the protection rod 184 to slowly move to the left. The slow movement of the protection rod 184 provides anti-impact protection for the preheating pipe 6.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
