[0024] EMBODIMENT

[0025] REFERENCE Figures 1-4 For the embodiment of the utility model, the embodiment provides a rapid heating and curing device, which can realize the effect of removing and excluding the waste slag on the surface of the filter screen 201 by the power of the airflow during hot return, and preventing excessive heat from flowing through the slag discharge port 206a.

[0026] The heating mechanism 100 comprises a box resistance furnace 101, a sealing door 102 hinged to the outer side of the box resistance furnace 101, a sheet metal cover 103 communicated with the top of the box resistance furnace 101, a hot return pipe 104 communicated with the other end of the sheet metal cover 103, and an air suction fan 105 adaptively installed in the inner cavity of the sheet metal cover 103.

[0027] It should be noted that the box resistance furnace 101 provides the main heating source for the workpiece heating process, the sealing door 102 prevents heat loss during the heating process and prevents external air from entering to affect the internal atmosphere, the sheet metal cover 103 guides the direction of hot air flow, the heat return pipe 104 circulates hot air to improve heating efficiency and reduce energy loss, and the air suction fan 105 can enhance hot air flow through forced ventilation to improve heating speed and uniformity.

[0028] The filtering mechanism 200 includes a filter screen 201 fixedly installed on the inner wall of the heat return pipe 104, a hollow plate 202 fixedly connected to the inner wall of the heat return pipe 104, an axial flow impeller 203 fixedly installed on the surface of the hollow plate 202 away from the filter screen 201 and matched with the air suction fan 105, a T-shaped rod 204 fixedly installed on the inner surface of the axial flow impeller 203, a cleaning plate 205 fixedly connected to the outer end surface of the T-shaped rod 204 and matched with the filter screen 201, a slag discharging assembly 206 matched with the waste slag swept off by the cleaning plate 205 and used for discharging the waste slag outside the heat return pipe 104, and a heat preservation assembly 207 for preventing excessive hot air from flowing out through the slag discharging assembly 206.

[0029] It should be noted that the filter screen 201 is used to capture solid particles in the exhaust gas to prevent them from entering the box resistance furnace 101 again, the hollow plate 202 is used to support the axial flow impeller 203 while allowing airflow to pass through, and the axial flow impeller 203 can be rotated by the airflow generated by the air suction fan 105 to drive the cleaning plate 205 to clean the waste slag on the surface of the filter screen 201 through the T-shaped rod 204.

[0030] Specifically, the end of the heat return pipe 104 away from the sheet metal cover 103 is in communication with the bottom of the box resistance furnace 101, and the outer surface of the cleaning plate 205 is in sliding contact with the outer surface of the filter screen 201.

[0031] Further, the slag discharging assembly 206 includes a slag discharging port 206a opened below the filter screen 201, and a slag collecting box 206b arranged outside the sheet metal cover 103 and matched with the slag discharging port 206a.

[0032] It should be further noted that the slag discharging port 206a is used to discharge the swept waste slag, and the slag collecting box 206b is used to collect the discharged waste slag.

[0033] Preferably, the slag discharging port 206a is located below the filter screen 201, and the slag collecting box 206b is arranged directly below the slag discharging port 206a.

[0034] It should be noted that the heat preservation assembly 207 comprises a fixed block 207a fixedly connected to the outer surface of the heat return pipe 104, a heat conducting sleeve 207b fixedly installed on the inner wall of the fixed block 207a, and a thermal expansion block 207c and a sliding block 207d arranged in the inner cavity of the heat conducting sleeve 207b.

[0035] The heat conducting sleeve 207b is used to transmit the temperature of the heat return pipe 104 to the thermal expansion block 207c, and the thermal expansion block 207c can be elastically deformed when heated and press the sliding block 207d to move linearly along the inner wall of the heat conducting sleeve 207b.

[0036] Further, the heat preservation assembly 207 further comprises an L-shaped rod 207e fixedly connected to the surface of the sliding block 207d away from the thermal expansion block 207c, a sealing plate 207f fixedly installed on the penetrating end of the L-shaped rod 207e and used in cooperation with the slag discharge port 206a, and a spring 207g sleeved on the outer surface of the L-shaped rod 207e.

[0037] It should be noted that the initial position of the sealing plate 207f is below the slag discharge port 206a, and when the sliding block 207d moves linearly, it can drive the L-shaped rod 207e and the sealing plate 207f to move synchronously, so that the sealing plate 207f moves to the position of the slag discharge port 206a, ensuring that the material is smoothly discharged through the slag discharge port 206a.

[0038] Specifically, the outer surface of the sliding block 207d is in sliding contact with the inner wall of the heat conducting sleeve 207b, the outer surface of the L-shaped rod 207e is in sliding contact with the inner surface of the heat conducting sleeve 207b, the outer surface of the sealing plate 207f is in sliding contact with the bottom of the heat return pipe 104, and the spring 207g is located on the inner side of the heat conducting sleeve 207b.

[0039] In use, after the box-type resistance furnace 101 is started to heat the workpiece, the suction fan 105 is operated to guide the hot air back into the furnace through the metal cover 103 and the heat return pipe 104, forming a heat return, accelerating the temperature rise and ensuring uniform temperature distribution. When the exhaust gas passes through the heat return pipe 104, the solid particles in the exhaust gas are removed by the filter screen 201. With the operation of the suction fan 105, the axial impeller 203 rotates to drive the cleaning plate 205 to slide along the surface of the filter screen 201 to remove the attached waste residue. The waste residue scraped off by the cleaning plate 205 passes through the slag discharge port 206a;

[0040] When the box-type resistance furnace 101 reaches the appropriate temperature: the heat conduction sleeve 207b transmits the temperature of the hot return pipe 104 to the thermal expansion block 207c, so that the thermal expansion block 207c elastically deforms and extrudes the sliding block 207d to move linearly along the inner wall of the heat conduction sleeve 207b, and then the sliding block 207d drives the L-shaped rod 207e and the blocking plate 207f to move synchronously, so that the blocking plate 207f moves to the position of the slag discharge port 206a, ensuring that the material is smoothly discharged into the slag collecting box 206b through the slag discharge port 206a;

[0041] When the temperature in the box-type resistance furnace 101 decreases: the thermal expansion block 207c restores by hand cooling, and the sliding block 207d, the L-shaped rod 207e and the blocking plate 207f are reset by the reaction force of the spring 207g, so that the blocking plate 207f blocks the slag discharge port 206a, thereby preventing excessive heat from flowing through the slag discharge port 206a.

[0042] In summary, through the cooperation of each component in the filtering mechanism 200, the waste slag on the filter screen 201 can be automatically cleaned by the cleaning plate 205 driven by the power of hot return, the equipment can be maintained for long-term stable operation, through the cooperation of the slag discharge assembly 206 and the heat preservation assembly 207, the position of the blocking plate 207f can be controlled by the thermal expansion block 207c sensing temperature change while ensuring the smooth discharge of waste slag, and the loss of excessive heat through the slag discharge port 206a is prevented, thereby achieving the effect of greatly improving the energy utilization rate.
