Description

Technical Field

[0001] The utility model relates to the field of feed production, in particular to a tube bundle drying device. Background Art

[0002] Drying is an important part of feed production. In this process, the water content of the feed needs to be reduced to a certain range to facilitate the subsequent processing and preservation of the feed. The drying process usually uses a tube bundle dryer. The tube bundle dryer is a large-scale continuous tube bundle drying equipment, including a shell and a tube bundle arranged in the shell. When hot steam passes through the tube bundle, heat is exchanged with the feed in the shell, and the feed is also stir-fried to achieve the purpose of drying the feed.

[0003] During actual operation, it was found that the feed entering the shell through the feed port tends to clump. There is a certain probability that these clumped feeds will stick between the tube bundles during the stir-frying process. If the feed sticks between the tube bundles for a long time, it is easy to burn, thereby igniting other feed in the shell, posing a safety hazard.

[0004] Therefore, a technical solution is currently needed to solve the technical problem that in the process of drying feed in the tube bundle dryer, agglomerated feed is easily adhered between the tube bundles, posing a risk of ignition. Utility Model Content

[0011] As a preferred solution of the utility model, the sleeve is an aluminum alloy structural member. The sleeve made of aluminum alloy has the characteristics of light weight, high temperature resistance, and high strength. The light weight can reduce the load of the sleeve on the tube bundle mechanism, the high temperature resistance can adapt to the high temperature environment of the drying process, and the high strength can bear the weight of the feed to avoid deformation.

[0013] As a preferred solution of the utility model, the side of the bottom box is provided with a limit screw, and the limit screw is connected to the plug block. The limit screw passes through the side wall of the bottom box and is connected to the plug block on the top of the cover body, so that the cover body is installed on the bottom box more stably and avoids accidental falling off during operation.

[0014] As a preferred solution of the utility model, the sleeve is a two-petal structure, including two symmetrically arranged shell petals, and the two sides of the shell petals are respectively provided with connecting pieces, and the connecting pieces are provided with connecting holes, and the connecting holes are equipped with bolts. The two-petal sleeve can be disassembled, which is convenient for the inspection and maintenance of the tube bundle mechanism in the sleeve after the sleeve is disassembled, and avoids the occurrence of material accumulation and blockage of the tube bundle mechanism after long-term use.
