Abstract

The invention discloses a two-channel air door structure used for fluid bed drying. The two-channel air door structure used for fluid bed drying comprises two air door bodies arranged in two air inlet spaces respectively, rotary shafts rotationally arranged in a machine seat barrel, and driving mechanisms used for driving the air door bodies to intermittently rotate along the rotary shafts. Each air door body is correspondingly provided with the rotary shaft and the driving mechanism. The machine seat barrel is provided with two hollow rectangular channels used for installation of the air door bodies. The air door bodies are symmetrically arranged on the rotary shafts and are in a rectangular shape matched with the hollow rectangular channels. The air door bodies and the hollow driving mechanisms are arranged outside the machine seat barrel, and bearings are arranged between the rotary shafts and the machine seat barrel. By means of the two-channel air door structure used for fluid bed drying, the one-time alternating response time can be shortened, and the accuracy of air flow control is improved. Meanwhile, the two channels can be communicated or isolated at the same time, and the applicable material range is widened.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a double-channel damper structure used for a drumming mechanism of a fluidized bed dryer. Background technique [0002] In the pharmaceutical process, materials need to be dried. At present, fluidized bed dryers are used for drying. The existing fluidized bed dryers have a good drying effect on solid non-viscous materials, but when drying solid viscous materials, the solid viscous materials are easily bonded into agglomerates, resulting in drying. poor effect. [0003] In order to improve the drying effect of the fluidized bed dryer, there is a new noise drum mechanism of the fluidized bed dryer. The drum noise mechanism includes a base cylinder 1 for sending hot air into the fluidized bed. 1 and the main air inlet passage 2 connected with the base cylinder 1, the damper door body 3 arranged between the base cylinder 1 and the air intake main passage 2, the base cylinder...
