Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a silencer for an adsorption dryer. Background Technology

[0002] In existing applications of silencers for adsorption dryers, the airflow generated during dryer operation often causes dust and impurities carried by the airflow to accumulate on the inner wall of the silencer due to its internal structure. Over time, this accumulation of dust and impurities reduces the internal space of the silencer, obstructs airflow, and consequently affects the silencer's noise reduction effect and lifespan. Furthermore, dust accumulation increases internal resistance, leading to increased energy consumption and a decline in the overall performance of the dryer. Utility Model Content

[0003] This utility model provides a silencer for an adsorption dryer, including a silencer and a filter screen. The filter screen is fixedly installed inside the silencer. A cleaning unit is provided on the silencer. The cleaning unit includes a housing, a motor, a drive shaft, a first bevel gear, a rotating shaft, a second bevel gear, and a cleaning brush. The housing is fixedly installed on the top of the silencer. The motor is fixedly installed inside the housing. The drive shaft is rotatably connected to the top of the silencer, and the top end of the drive shaft is fixedly connected to the drive end of the motor. The first bevel gear is fixedly installed at the bottom end of the drive shaft. The rotating shaft is rotatably connected to the middle part of the filter screen. The second bevel gear is fixedly installed at one end of the rotating shaft and meshes with the first bevel gear. The cleaning brush is fixedly installed at the other end of the rotating shaft.

[0004] Preferably, the silencer is provided with a collection unit for collecting impurities on the filter surface removed by the cleaning unit.

[0005] Preferably, the collection unit includes a collection pipe, a collection box, a vacuum fan, and a filter plate. The silencer has a through hole located below the filter screen. One end of the collection pipe is fixedly installed at the bottom of the silencer, and the collection pipe and the silencer are connected through the through hole. The top of the collection box is fixedly connected to the other end of the collection pipe. The vacuum fan is fixedly installed inside the collection box, and the filter plate is fixedly installed inside the collection box, located above the air inlet of the vacuum fan.

[0006] Preferably, the drive shaft is connected to the top of the muffler via a sealed bearing, the inner ring of the sealed bearing being interference-fitted with the drive shaft, and the outer ring of the sealed bearing being fixedly connected to the muffler.

[0007] This invention provides an improved adsorption dryer silencer, which, compared with existing technologies, has the following improvements and advantages: By incorporating a filter screen inside the silencer, this invention effectively intercepts dust and impurities from the outside air, preventing them from entering the silencer and maintaining its cleanliness. This ensures the stability of the silencing effect and the long-term efficient operation of the dryer. Simultaneously, the cleaning unit allows for regular cleaning of the filter screen's surface, preventing clogging caused by dust and impurities and maintaining the filter screen's ventilation performance. During cleaning, the collection unit automatically collects the cleaned dust and impurities, preventing these substances from being carried back onto the filter screen by the airflow, ensuring the filter screen's continuous and efficient filtration capability.
