Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a dryer exhaust gas filtering device with an oil collecting function. Background Art

[0002] Injection molding machine dryer is a kind of equipment used in plastic processing, mainly used to remove moisture from plastic particles or powder to ensure the quality of plastic products. Injection molding dryer will not only produce waste gas containing dust particles and non-methane hydrocarbons and other harmful substances during the injection molding process, but also may be accompanied by the generation of oil mist.

[0003] Oil mist mainly comes from the lubricating oil or other working fluids inside the machine, which may evaporate or splash under the action of high temperature or mechanical movement, forming oil in the exhaust gas. The presence of oil mist not only increases the pollution level of the exhaust gas, but also may cause blockage or corrosion to the subsequent treatment equipment, affecting the treatment effect and equipment life. Therefore, in the treatment of injection molding dryer exhaust gas, oil removal is a key link.

[0004] However, the exhaust gas filter device of the injection molding machine dryer in the prior art simply filters the exhausted exhaust gas, resulting in oil mist remaining in the exhaust gas filter device. Moreover, after the exhaust gas filter device is used for a long time, a large amount of oil mist accumulates in the exhaust gas filter device and cannot be discharged, which affects the filtering effect of the entire exhaust gas filter device and reduces its service life.

[0014] Preferably, the base has a tendency to collapse along the oil outlet direction. Through the above improvements, waste oil and ash are guided to flow into the oil collecting shell along the inner wall of the base.

[0015] Preferably, sealing rings are formed at both ends of the filter element and are inserted into the fixing grooves. Through the above improvements, the sealing rings are respectively inserted into the fixing grooves of the first fixing part and the second fixing part, thereby greatly improving the stability of the filter element installation and improving the sealing between the filter element and the main body and the base.

[0016] Preferably, the oil collecting shell and the oil collecting cover are made of transparent material. Through the above improvements, the amount of collected oil can be directly observed, which is more convenient for daily maintenance.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0018] By connecting the air intake pipe to the dryer, the exhaust gas generated by the dryer enters into the main body through the air intake pipe, and the filter element inside the main body filters the exhaust gas. The filtered exhaust gas can be discharged or connected to another filtering structure, and the waste oil generated by the dryer can enter into the oil collecting device through the oil outlet pipe and be collected. Therefore, not only the exhaust gas generated by the dryer can be filtered, but also the waste oil generated by the dryer can be collected, which can not only reduce the pollution caused by the desiccant exhaust gas, but also recycle the waste oil, thereby improving the service life of the exhaust gas filtering device, and the hot air after filtration can be recycled into the dryer, realizing the recycling of heat energy and saving electricity costs.
