Description

Technical Field

[0001] The utility model belongs to the technical field of fan regulating dampers, in particular to a main fan regulating damper of a dryer which can be recycled after dehumidification. Background Art

[0002] The dryer's principle is to first set the air inlet temperature (with upper and lower temperature limits) to heat the heater, then use the fan to continuously draw in air, generating hot air that flows into the container to dry it. The amount of air introduced or exhausted by the fan is adjusted using a damper.

[0003] After searching, the patent announcement number CN209385395U discloses a petal-shaped fan damper, which relates to the technical field of fan damper technology and solves the problems of uneven rotation and difficult blade adjustment. The invention comprises a casing, a plurality of support rods fixed inside the casing, a center block being fixed to the support rods together, a plurality of air-regulating blades being rotatably arranged inside the casing, a plurality of rotating shafts being passed through the side wall of the casing, and a limiting rod being fixed at the end away from the air-regulating blades, a plurality of supports being fixed to the outer peripheral wall of the casing, a swing ring being provided with the plurality of supports rotating together on the circumference of the casing, a plurality of waist-shaped grooves being provided in the swing ring, a plurality of sliders being provided on the outer peripheral side wall of the casing for reciprocating sliding, and a limiting ring being elastically provided on the side of the slider away from the casing. The utility model drives the limiting rod and the rotating shaft to swing at a certain angle through the swing ring, thereby making the adjustment of the air-regulating blades smoother and avoiding the phenomenon of jamming. The limiting rod is locked by the limiting ring, making the air-regulating blades more secure after adjustment.

[0004] In actual use, the existing main fan regulating damper of the dryer that can be recycled after dehumidification is generally adjusted by the staff on the size of the air outlet of the damper by manual adjustment. However, the manual adjustment of the air outlet of the damper has low accuracy, which affects the drying effect. Frequent adjustment also increases the workload of the staff. In addition, when the air regulating blades are deformed due to the long-term action of wind, the staff need to disassemble and replace the air regulating blades. However, it is not easy for the staff to disassemble and replace the air regulating blades. Therefore, a main fan regulating damper of the dryer that can be recycled after dehumidification is designed. Utility Model Content

[0046] Working principle: When in use, the staff installs the flange 130 on one end of the device to one end of the main fan of the dryer. After the staff connects the device to the external power supply, the wind generated by the main fan of the dryer will flow in the damper cylinder 100. At this time, the air volume detection sensor 180 can detect the air volume discharged from one end of the damper cylinder 100 in real time and transmit the detected air volume data value to the single-chip microcomputer in the control box 120. When the detected air volume data value is greater than or less than the preset air volume data value, the single-chip microcomputer controls the electric push rod 220 to extend and retract. When the electric push rod 220 extends and retracts, it drives the annular rotating plate 210 to rotate forward or backward. Reversal, when the annular rotating plate 210 rotates forward or reverse, the first connecting shaft 314 will rotate forward or reverse through the cooperation of the linkage column 211 and the linkage plate 311. When the first connecting shaft 314 rotates forward or reverse, it will indirectly drive the air regulating blade 315 to rotate forward or reverse. The air regulating blade 315 rotates forward or reverse to adjust the air volume at one end of the damper cylinder 100. Therefore, the utility model realizes automatic adjustment of the air volume, improves the accuracy of the air volume adjustment, avoids the air volume of the damper cylinder 100 being too large or too small to affect the product drying effect, and reduces the workload of the staff.
