Description

Multilayer drying tower convenient to wash

Technical Field

The utility model relates to a desiccator technical field especially relates to a multilayer drying tower convenient to wash.

Background

The vibration countercurrent dryer is mainly suitable for drying various traditional Chinese medicine pills, such as honeyed pills, water pills, concentrated pills, dropping pills and the like, is suitable for drying granular materials in the industries of pharmacy, chemical industry, food, feed, plastics and the like, and is suitable for drying materials in short strips, granules, blocks, spheres and the like. At present, the vibration countercurrent dryer used in China on a large scale dries materials by conveying hot air to accelerate the evaporation of water on the surfaces of the materials to be dried, and has a good drying effect. But to the material pile up the problem on the drying tray, the washing problem, dry moisture control can't get fine solution always, especially when material surface humidity is higher, hardly in time dredges the material, once is difficult to reach the material that dry moisture required. In addition, the cleaning work of the drying tray is complex, and each layer needs to be disassembled, so that more manpower and time are consumed.

For example, the composite multilayer centrifugal vibration countercurrent dryer (publication number: CN207922808U) disclosed in chinese patent, when drying, the materials are conveyed as follows: and starting a vibrating motor, simultaneously throwing wet materials into the center position of the top layer drying disc from a feeding bin, and enabling the wet materials to move to the edge of the sieve plate along the spiral sheet from the center under the action of the exciting force and fall to the center position of the sieve plate of the next drying disc through the blanking groove. The material needs to move along the direction of flight, and the vibration effect that only relies on vibrating motor is not obvious enough, when material surface humidity is great, easy putty, cause the material to pile up. In addition, when the drying operation is completed, the residual materials in the drying tray are difficult to clean.

The cleaning process of the multilayer spiral vibration dryer (publication number: CN207180297U) disclosed by the Chinese patent is as follows; firstly, a binding ring between the top layer drying plate and the adjacent middle layer drying plate is detached, a hoisting lifting hook is connected with a hoisting lifting lug on the top layer drying plate, a hoisting cylinder is started, and the top layer drying plate is hoisted until the safety lifting hook can hook the safety lifting lug. The spiral guide plate is disassembled to carry out all-around cleaning on the drying discs, the processes are repeated, each layer of drying discs are sequentially disassembled and then installed until the drying discs on the bottom layer are cleaned, and the cleaning work of the whole equipment is completed. Although the drying pan can also be cleaned, it has a number of drawbacks; 1. the drying plate needs to be cleaned frequently, the drying plate needs to be cleaned after materials are dried each time, the drying plate needs to be disassembled layer by layer in the cleaning mode, a large amount of manpower is needed, and the cleaning labor cost is high; 2. before cleaning the drying tray, the hoisting device needs to be operated to hoist the drying tray layer by layer, so that the drying tray is complicated to clean, difficult and dangerous; 3. when dismantling and installing multilayer drying dish, need a lot of to the collar of fixed drying dish usefulness dismouting, and the collar after many times dismouting can slowly warp for the gas tightness between the adjacent drying dish descends, leads to drying effect to reduce.
