[0031] The top and bottom ends of the sliding sleeve 3 are fixedly provided with sealing rings 17, the inner sides of the two sealing rings 17 are in contact with the outer ends of the air-drying and crushing chamber 1 and the discharge chamber 5 respectively, and the outer end of the discharge chamber 5 is fixedly provided with two connecting arms 6, and the bottom ends of the two connecting arms 6 are fixedly connected to the air-drying and crushing chamber 1 respectively;

[0032] A fixing ring 15 is provided on the inner wall of the sliding sleeve 3 , a material stopper ring 16 is fixedly provided on the inner wall of the fixing ring 15 , a first fastening bolt is threadedly provided on the inner side of the fixing ring 15 , and a second fastening bolt is threadedly provided on the outer end of the sliding sleeve 3 .

[0033] The material is dried inside the air-drying and crushing chamber 1 and crushed under the action of the crushing assembly 13. The crushed material moves to the discharge chamber 5 through the air-drying and crushing chamber 1 driven by hot air. During the movement, the material passes through the sliding sleeve 3. The blocking ring 16 installed inside the sliding sleeve 3 can block the large and incompletely crushed materials. Only the fully crushed materials can be discharged outward in the end, so that the materials can be dispersed more evenly, avoiding the problem of unstable drying speed caused by high-speed dispersion of materials, thereby improving the use effect and life of the flash dryer.

[0034] The sliding sleeve 3 is installed through the elastic component 7 to replace the retaining ring 16. Figure 1-3 As shown, an elastic component 7 is provided on one side of the sliding sleeve 3, and the elastic component 7 includes a telescopic rod 701, and end plates 703 are fixedly provided at both ends of the telescopic rod 701;
