the drainage device of the existing dryer mainly comprises a manual valve, a filter and a drainage valve which are sequentially communicated, wherein the filter is a Y-shaped filter, and the drainage valve is an automatic drainage valve with a physical floater, so that the labor intensity of operators is reduced. The physical float type automatic drain valve is mainly opened by the buoyancy of a float in the drainer, and the liquid level in the drain valve rises and falls corresponding to the opening and closing of the valve. The drain valve can open and close the valve in time according to the change of the liquid level, can better control the liquid level in the air bag, is not easy to cause water accumulation, and can meet the use requirement of a field.

Due to the pulverization of the drying agent and the falling of the rust on the inner layers of the pipeline and the equipment, the impurities with large particles can enter the filter through the manual valve, so that the filter is frequently blocked and cannot be drained normally, the filter needs to be frequently cleaned, and the maintenance cost is high.

Meanwhile, dust with small particles can enter the drain valve through the filter and is accumulated at the sealing opening of the floater of the drain valve, a large amount of dust is easy to accumulate, accumulated dust can form scales or directly block the sealing opening, the scales can cause the sealing opening to be not tight, dry gas is easy to leak under the condition of not draining, and the sealing opening is blocked and cannot drain water.

In order to solve the technical problem, an embodiment of the present invention provides a drainage buffer device for a dryer, which can effectively reduce impurities entering a filter and a drain valve, thereby avoiding the situation that the filter is blocked, the drain valve is not sealed tightly or the sealing port is blocked.

By providing the above-mentioned drainage buffer device, water generated by the dryer enters the device through the manual valve and enters the first buffer chamber 14 from the inlet 12, and since the water flow input from the inlet 12 flows to the inner wall of the first buffer chamber 14, the first buffer chamber 14 can buffer the water flow, and the water flow enters the second buffer chamber 15 and flows to the filter from the outlet 13 after being buffered by the second buffer chamber 15. Because entry 12 and export 13 all are located the lateral wall of inner chamber 11, and first cushion chamber 14 and second cushion chamber 15 can cushion the speed reduction to rivers to can make the impurity part that carries in the rivers sink into the bottom of inner chamber 11, reduce the impurity that gets into the filter, and then avoid appearing the condition that the filter needs frequent washing, reduce the maintenance cost.

In addition, partial impurities sink into the bottom of the inner cavity 11, dust entering the drain valve can be reduced, a small amount of dust is easy to discharge along with water flow when the drain valve is opened, and accumulation is not easy, so that the situation that the dust is scaled or blocks a sealing opening can be relieved, the service life of the drain valve is prolonged, and the use cost is reduced.
