Description

Technical Field

[0001] The utility model relates to the technical field of compressed air filtering, in particular to a high-efficiency filtering device for a compressed air system of a granulator. Background Art

[0002] Air generally contains harmful substances such as dust, rust, and moisture. After the air containing these harmful substances is compressed, it enters the filter device of the air filter. When the compressed air passes through the filter device, a coalescence effect will occur, that is, some particles will condense when passing through this channel, and larger particles will remain on the filter net. Because the particles are larger, they are adsorbed by the filter material. After these small particles condense for a long time, the moisture will become larger water droplets. Then the compressed air will enter the separation chamber. After entering the separation chamber, the air flow rate will naturally slow down. When the air flow rate slows down, the particles flowing from the previous channel will gather again. There is a honeycomb-like water mist in the separation chamber, and the water mist flowing through will condense on this water collector. The water that has not condensed is water with impurities, and this water with impurities will flow along the bottom of the device.

[0003] During workshop production, condensed impurity water accumulates at the bottom of the filter and cannot be discharged, which affects the filtration efficiency and effect; and the filter plate will be clogged after long-term use, resulting in a serious decrease in filtration efficiency. The existing technology requires manual processing after disassembly, which seriously affects the normal production. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a high-efficiency filtering device for a compressed air system of a granulator. By setting an inclined guide plate and an impurity water storage tank, the impurity water accumulated at the bottom of the filter can be discharged in time, thereby greatly reducing its influence on the filtering efficiency and filtering effect; by setting a return pipe and a rotating booster plate, the filter plate is back-purged by the filtered compressed air, and the rotating booster plate is used to control the channel of the purge air, thereby greatly improving the purge efficiency and thus improving the filtering efficiency.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The high-efficiency filtering device of the compressed air system of the granulator comprises a screw air compressor, which is connected to a condensing compressed air dryer through a buffer tank, the condensing compressed air dryer is connected to an air filter element through a filter, the air filter element is connected to a clean compressed air storage tank, the filter is connected to an impurity water storage tank through an impurity water storage tank inlet pipeline, a filter plate is arranged inside the filter, and a rotating supercharging plate is arranged above the filter plate.

[0007] The filtering method of the filter is bottom-in and top-out, and the air enters the filter from the bottom of the filter plate.

[0008] A filter inlet pipe is connected between the condensing compressed air dryer and the filter, and a filter outlet pipe is provided between the filter and the air filter element.

[0009] The connection between the filter inlet pipe and the filter is located below the filter plate, and the connection between the filter and the air filter element is located above the filter plate.

[0010] An inclined guide plate is provided below the filter plate, a vibrator is provided on the vertical wall of the filter, and a back-purge inlet is provided above the filter. The vibrator is used to increase the falling speed of impurities on the filter plate.

[0012] The clean compressed air storage tank is provided with a pipeline for entering the high-speed mixing granulator, the pipeline for entering the high-speed mixing granulator is connected with a pipeline for entering the boiling granulator, and the pipeline for entering the high-speed mixing granulator is connected with the back-purge inlet through a return pipeline.

[0013] When the filter plate needs to be back-purged, the rotary booster plate is pushed down until it contacts the filter plate by rotating the handle. The rotary booster plate is tangent to the inner diameter of the filter, and the compressed gas enters the filter through the return pipe. The compressed air blows the filter plate through the rotary booster plate channel. By controlling the rotary handle, each filter hole of the filter plate is blown.

[0014] The air filter element is connected to the impurity water storage tank through a pipeline.

[0015] The working principle of the utility model is:

[0016] The compressed air in the screw air compressor enters the condensing compressed air dryer through the buffer tank, and then enters the filter through the filter inlet pipe. The compressed air is filtered in the form of "bottom-in and top-out". After the filtration is completed, it enters the clean compressed air storage tank through the air filter element. The impurity water accumulated at the bottom of the filter is discharged to the impurity water storage tank through the impurity water storage tank inlet pipe; when the filter plate needs to be back-purged, the rotary booster plate is pushed down to contact the filter plate by rotating the handle. The rotary booster plate is tangent to the inner diameter of the filter, and the compressed gas enters the filter through the return pipe.

Among them, the filter mode of the filter is bottom-in and top-out, and the air enters the filter from the bottom of the filter plate.
