Description

Technical Field

[0001] The present invention relates to the technical field of resistance furnaces, and particularly to an energy-saving box-type resistance furnace. Background Art

[0002] An energy-saving box-type resistance furnace generally consists of parts such as a furnace body, resistance heating elements, temperature control elements, and a sealing device.

[0003] The patent with the patent announcement number CN220981937U relates to an energy-saving heat treatment box-type resistance furnace, including a resistance furnace and a sealed box door. An energy-saving insulation device is arranged inside the resistance furnace, and a clamping and rotating device is arranged on the top of the resistance furnace. The clamping and rotating device includes a power unit and a rotating unit. In this energy-saving heat treatment box-type resistance furnace, through the setting of multiple layers of heat insulation materials in the energy-saving insulation device, heat inside the heating inner liner can be thermally insulated and sealed, preventing rapid heat dissipation, being more energy-saving and environmentally friendly. The power unit drives the electric telescopic rod to rotate inside the sealed bearing, so that the clamping plate at the left end of the electric telescopic rod rotates, driving another clamping plate to rotate through a rotating shaft inside another sealed bearing, thereby driving the material between the two clamping plates to rotate, making it heat more evenly, further improving the heating efficiency, and being more energy-saving and environmentally friendly.

[0004] In the above patent, the power unit drives the electric telescopic rod to rotate inside the sealed bearing, so that the clamping plate at the left end of the electric telescopic rod rotates, driving another clamping plate to rotate through a rotating shaft inside another sealed bearing, thereby driving the material between the two clamping plates to rotate, making it heat more evenly, further improving the heating efficiency, and being more energy-saving and environmentally friendly. However, it is difficult to control the feeding speed of the metal powder to be processed. When the feeding speed is too fast, the metal powder cannot be fully heated or melted, thus affecting its physical and chemical properties. When the feeding speed is too slow, it will cause overheating or uneven temperature distribution in some areas of the furnace body, thereby affecting the processing quality of the metal powder.

[0015] The present invention provides an energy-saving box-type resistance furnace, which has the following beneficial effects:

[0016] (1) For this energy-saving box-type resistance furnace, the agglomerated metal powder is dispersed by the rotation of the stirring rod. By dispersing the agglomerated powder, it helps to improve the melting efficiency of the metal powder, enabling it to reach the melting temperature more quickly and evenly inside the furnace body, thereby improving production efficiency and shortening the heating and processing time. The bottom of the hollow plate is blocked by the reciprocating movement of the A-shaped plate to control the feeding of the metal powder. By avoiding energy waste caused by too fast feeding or insufficient heating caused by too slow feeding, the overall energy utilization efficiency is improved, and the energy-saving goal of the furnace body is thus achieved.

[0017] (2) For this energy-saving box-type resistance furnace, the falling metal powder is distributed by the rotation of the material distributing frame, making it relatively evenly distributed inside the placement frame. The uniform distribution of the metal powder helps to achieve uniform heating inside the furnace, thus avoiding processing defects caused by temperature differences.

[0018] (3) For this energy-saving box-type resistance furnace, if a leakage occurs at the connection between the first connecting pipe and the furnace body, by triggering the button instantly when the leakage occurs in the connecting pipe and immediately stopping the operation of the furnace body, it is possible to prevent a greater accident caused by the leakage, thereby protecting the safety of the equipment and personnel.

[0019] (4) For this energy-saving box-type resistance furnace, by rotating the separation frame to contact the inner wall of the first connecting pipe and scrape it, through the rotation of the separation frame and scraping the inner wall of the first connecting pipe, oxides or other impurities can be removed, thereby ensuring unobstructed transmission of air flow and heat, and helping to improve the pressure relief efficiency of the pressure relief equipment.

[0020] (5) For this energy-saving box-type resistance furnace, the pressure relief pipe can only move slowly through the slow movement of the protective frame to protect the pressure relief pipe. The slow movement of the protective frame can effectively limit the excessive displacement of the pressure relief pipe, thereby reducing damage caused by severe vibration or air flow impact.

The pressure relief device 11 can be used to relieve pressure and cool down the inside of the furnace body 1. At the same time, the high-temperature pressure gas can be secondary introduced into the furnace body 1 through the pressure relief device 11 and the energy-saving pipe 15. By avoiding energy waste due to too fast feeding or insufficient heating due to too slow feeding, the overall energy utilization efficiency is improved, and the energy-saving goal of the furnace body 1 is achieved.

The continued rotation drives the stirring rod 7 to continue rotating, and the stirring rod 7 continues to rotate to break away from the contact with the inclined plate 10. After the inclined plate 10 breaks away from the contact with the stirring rod 7, the U-shaped rod 9 moves downward and resets under the elastic force of spring No. 1. The U-shaped rod 9 moves downward and resets, driving the A-shaped plate 91 to move downward and reset. The A-shaped plate 91 moves downward and resets to break away from the contact with the hollow plate 8 and releases the obstruction to the hollow plate 8. The A-shaped plate 91 moves back and forth to block the bottom of the hollow plate 8 to achieve the effect of controlling the feeding of metal powder. The broken metal powder enters the furnace body 1 and falls into the placement frame 2. At the same time, valve one is closed to seal the furnace body 1. After the furnace body 1 is sealed, press button 177 to start the furnace body 1 to process the metal powder.

[0035] See also Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, a material distribution component for improving the uniform distribution of metal powder is provided on the right side of the furnace body 1, and a buffer component is provided on the right side of the furnace body 1. The material distribution component includes a material distribution rod 171, a moving rod 172, a material distribution frame 173 and a button 177. The material distribution rod 171 rotatably penetrates the right side of the heat insulation frame 3, the moving rod 172 is fixedly installed on the circumferential surface of the material distribution rod 171, the material distribution frame 173 is fixedly installed on the circumferential surface of the material distribution rod 171, the button 177 is fixedly installed on the right side of the furnace body 1, the button 177 is electrically connected to the furnace body 1, the material distribution rod 171 penetrates the inner and outer walls of the furnace body 1, and a hairspring is provided between the material distribution rod 171 and the heat insulation frame 3.

[0036] A detection frame 174 is fixedly installed on the right side of the furnace body 1. A detection plate 175 is slidably installed on the inner wall of the detection frame 174. A detection rod 176 is fixedly installed on the front side of the detection plate 175. The button 177 is pressed by the detection rod 176 to drive the furnace body 1 to stop working. By triggering the button 177 immediately when the first connecting pipe 12 leaks and immediately stopping the furnace body 1 from working, it is possible to prevent larger accidents caused by leakage, thereby protecting the equipment and personnel safety.

[0037] A tooth block 178 is fixedly installed on the inner wall of the material distribution rod 171. A second spring is provided between the detection plate 175 and the detection frame 174. The second spring can drive the detection plate 175 to reset. The rear side of the button 177 is set as an inclined surface.

[0038] The buffer component includes a separation plate 181, a separation rod 182, a gear 183, a rack 184 and a separation frame 185. The separation plate 181 is fixedly installed on the right side inner wall of the furnace body 1. The separation rod 182 rotatably penetrates the left and right walls of the separation plate 181. The gear 183 is fixedly installed on the circumferential surface of the separation rod 182. The rack 184 is slidably installed on the right side inner wall of the furnace body 1. The separation frame 185 is fixedly installed on the circumferential surface of the separation rod 182. The separation frame 185 contacts the inner wall of the first connecting pipe 12. The rack 184 meshes with the gear 183, and the rack 184 meshes with the tooth block 178. By rotating the separation frame 185 and scraping the inner wall of the first connecting pipe 12, oxides or other impurities can be removed, thereby ensuring that the transmission of air flow and heat is unobstructed, which helps to improve the pressure relief efficiency of the pressure relief device 11.

[0039] On the left side of Valve 2, a protective frame 186 is fixedly installed. Inside the protective frame 186, a protective plate 187 is slidably installed. On the left side of the protective plate 187, a protective rod 188 is fixedly installed. On the left side of the protective rod 188, a protective hole 189 is provided. Inside the protective frame 186, there is liquid. The protective frame 186 can only move slowly, so that the pressure relief pipe 14 can only move slowly and protect the pressure relief pipe 14. Through the slow movement of the protective frame 186, the excessive displacement of the pressure relief pipe 14 can be effectively restricted, thereby reducing the damage caused by severe vibration or air flow impact.

[0040] A third spring is provided between the protective plate 187 and the protective frame 186. Through the third spring, the protective plate 187 can be driven to reset. The left side of the protective rod 188 is fixedly connected to the furnace body 1. The separation frame 185 is in contact with the inner wall of the first connecting pipe 12.

[0041] During the operation of this embodiment: The rotating rod 6 rotates to drive the linkage rod 16 to rotate. The linkage rod 16 rotates and contacts the moving rod 172 and extrudes the moving rod 172. The moving rod 172 rotates under the extrusion of the linkage rod 16. The moving rod 172 rotates to drive the material distributing rod 171 to rotate. The material distributing rod 171 rotates to drive the material distributing frame 173 to rotate. The material distributing frame 173 rotates to distribute the falling metal powder so that it is relatively evenly distributed inside the placing frame 2. If there is a leakage at the connection between the first connecting pipe 12 and the furnace body 1, the pressurized gas leaking between the first connecting pipe 12 and the furnace body 1 will directly enter the detection frame 174. The pressurized gas entering the detection frame 174 will extrude the detection plate 175. The detection plate 175 moves forward under the extrusion of the pressurized gas inside the detection frame 174. The detection plate 175 moves forward to extrude the second spring. The second spring deforms and stores energy under the extrusion of the detection plate 175. At the same time, the detection plate 175 moves forward to drive the detection rod 176 to move forward. The detection rod 176 moves forward and contacts the inclined surface of the button 177 and extrudes the inclined surface of the button 177. The button 177 is pressed by the detection rod 176 to drive the furnace body 1 to stop operating.

[0042] The material distribution rod 171 rotates to drive the tooth block 178 to rotate. The rotation of the tooth block 178 squeezes the rack 184. The rack 184 moves downward under the extrusion of the tooth block 178. The downward movement of the rack 184 contacts the gear 183 and squeezes the gear 183. The gear 183 rotates under the extrusion of the rack 184. The gear 183 drives the separation rod 182 to rotate. The rotation of the separation rod 182 drives the separation frame 185 to rotate. The rotation of the separation frame 185 contacts the inner wall of the first connecting pipe 12 and scrapes the first connecting pipe 12. After the processing of the metal powder is completed, the second valve is opened and the pressure relief device 11 is started to recover the high-temperature pressurized gas inside the furnace body 1. If the high-temperature pressurized gas impacts the pressure relief pipe 14, the pressure relief pipe 14 moves to the right under the impact of the high-temperature pressurized gas. The rightward movement of the pressure relief pipe 14 drives the protection frame 186 to move to the right. The rightward movement of the protection frame 186 causes the liquid on the left side of the protection frame 186 to be squeezed by the protection plate 187. When the liquid on the left side of the protection frame 186 is squeezed by the protection plate 187, the liquid on the left side of the protection frame 186 can only move slowly through the protection holes 189. The fact that the liquid on the left side of the protection frame 186 can only move slowly through the protection holes 189 makes the protection frame 186 can only move slowly. The fact that the protection frame 186 can only move slowly makes the pressure relief pipe 14 can only move slowly and protects the pressure relief pipe 14.
