Penetrating reverse-flow type fluidization drying tower

Abstract

The invention discloses a penetrating reverse-flow type fluidization drying tower. A hydraulic telescopic device is arranged at the top of the drying tower to be connected with a transmission shaft, the transmission shaft penetrates through a tower body and can be vertically driven by the hydraulic telescopic device, and a vibration source is arranged on the transmission shaft to transmit vibration. A plurality of layered repetition structures composed of screen mesh conical covers and screen mesh conical discs are arranged in the drying tower body, certain clearances exist between the conical discs and the conical covers, and the conical discs and the conical covers are fixed to the tower wall through elastic connection; the conical discs and the conical covers are connected with material drop pipes and shaft sleeves respectively, the transmission shaft is provided with a plurality of conical plugs, the conical plugs can close the material drop pipes when moving upwards, and the conical plugs can open the material drop pipes when upwards close to the shaft sleeves. Through the screen mesh conical covers, the screen mesh conical discs, the material drop pipes, the telescopic vibration transmission shaft and the conical plugs, penetrating, reverse flowing, boiling and fluidization drying of natural wind on materials are creatively achieved, the classical hot air drying mode is completely surpassed, more energy is saved, drying quality is higher, electricity consumed by a fan is lower, and the application prospect is wider.

Description

technical field

[0001] The invention relates to a drying tower, in particular to a penetrating countercurrent fluidized drying tower. Background technique

[0002] The drying tower is the core component of the tower dryer. The quality of the drying equipment depends to a large extent on the internal structure of the drying tower. The existing drying equipment needs to consume heat continuously during the drying process, and the efficiency is not high, and the energy consumption is relatively high. big.

[0003] If a drying tower can be designed to achieve penetrating countercurrent fluidized drying of materials under the premise of low or even zero heat consumption, it will be of great significance for improving drying efficiency and realizing energy saving and emission reduction. Contents of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a drying tower with a simple and pract...
