Technical Field

[0001] The utility model relates to the technical field of flash dryers, and particularly relates to an air inlet adjusting device for a flash dryer. Background Art

[0002] A flash dryer is a new type of continuous drying equipment integrating drying, pulverizing and screening, and is particularly suitable for drying filter cake-like, paste-like and thin slurry-like materials. The drying time of wet materials in the drying tower is only five to eight seconds, and the moisture evaporates instantly. The quality of the dried product is greatly related to the drying temperature, wind speed, air volume and crushing speed.

[0003] When the existing flash dryer intakes air, it is not convenient to adjust the size of the intake air volume according to requirements. Different types and moisture levels of materials require different hot air flow rates, with weak adjustability and low flexibility. Therefore, an air inlet adjusting device for a flash dryer is needed. Summary of the Utility Model

One end of the dryer body is fixedly connected with an air inlet pipe. One end of the air inlet pipe is provided with an adjusting pipe. The inner wall of the adjusting pipe is fixedly connected with an annular clamping groove. The outer surface of the annular clamping groove is clamped with a hot air pipe. The inner wall of the annular clamping groove is slidably connected with an adjusting plate. An annular cavity is left inside the adjusting pipe. The outer surface of the adjusting pipe is fixedly connected with a cylinder. The output end of the cylinder is fixedly connected with a telescopic rod. A sliding groove is opened on the inner wall of the adjusting pipe. One end of the telescopic rod is fixedly connected with a sliding rod. One end of the sliding rod is fixedly connected with an adjusting frame. The sliding rod penetrates through the inside of the sliding groove. The adjusting frame is fixedly connected with one side surface of the adjusting plate.

[0006] By adopting the above technical solutions, when the staff uses it, the adjusting pipe and the air inlet pipe are installed, and the hot air pipe is clamped corresponding to the annular clamping groove, so that hot air can be introduced. When adjusting the air inlet, the staff starts the cylinder. The cylinder drives the telescopic rod to extend. The telescopic rod moves telescopically inside the annular cavity, so that the sliding rod slides on the inner wall of the sliding groove, driving the adjusting frame to move, so that the adjusting plate slides on the inner wall of the annular clamping groove. The adjusting plate moves out from the inner wall of the annular clamping groove to generate a gap, thereby adjusting the air inlet volume according to the size of the gap. It has strong adjustability, simple operation, no air leakage outside during adjustment, and strong airtightness.
