Automatic fluidized bed suspension material bin cleaning device

Abstract

The invention relates to an automatic fluidized bed suspension material bin cleaning device which comprises a housing, a hopper, an air intake device and a discharge port; a feed port is formed in the left end of the housing, and is connected with the hopper; a material distributing device is arranged at the lower end of the hopper; an air outlet is formed in the upper end of the housing; a discharge port is formed in the lower end of the housing; a cleaning mechanism is arranged in the housing, and comprises a suspension plate, a vibration motor, a link mechanism and a spring; the vibration motor is connected with the link mechanism; the link mechanism is connected with the suspension plate through the spring; an air distributing chamber is formed below the cleaning mechanism, and is connected with the air intake device; the air intake device comprises a blower, an air valve and a heater; the blower is connected with the air distributing chamber through the heater; and the air valve is arranged between the heater and the air distributing chamber. The suspension plate is driven to vibrate through the vibration motor, so that the problem of dust accumulation and agglomeration in a wind field is effectively solved, accumulated and agglomerated dust automatically falls off through vibration, the outage cleaning time is saved effectively and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vibrating fluidized bed dryers, in particular to an automatic cleaning device for a fluidized bed suspension material box. Background technique [0002] Fluidized bed dryers are widely used in the fields of chemical industry, pharmaceuticals, agricultural and forestry special products, food, light industry, etc., and are general-purpose mechanical products with a large quantity and a wide range. Vibration fluidized bed is a gas-solid fluidization technology that introduces vibration energy into ordinary fluidized bed to improve fluidization quality. It can form a uniform fluidization state at a very low fluidization gas velocity. Due to the pulsation of particles, the contact between gas-solid and solid-solid is strengthened, and the chance of bonding is reduced, so the transfer rate is improved and the production process is strengthened; the fluidized bed dryer can be divided into two types: hanging type...

Problems solved by technology

[0003] When the granular material is dried in an ordinary fluidized bed dryer, the material particles should be uniform and have certain specifications, otherwise, groove flow and stagnation zone will be formed. When the particle size distribution is wide, the entrainment is serious, and it is easy to agglomerate when the humidity is high. , due to the back-mixing of particles, the distribution range of particle residence time is large, and the moisture content of particles is uneven, so the application range of ordinary fluidized bed dryers is limited

When the material is suspended and flows through the ventilation screen, due to the problem of material dust, agglomeration, and the level of the screen, when the drying air of the material is combined with the induced air to form the material suspension and heating process, due to uneven or too high heating, some Ventilation mesh holes are blocked, fluidized bed material and high temperature hot air contact parts are prone to accumulation and chemical phenomenon, this accumulation is easy to deteriorate when exposed to high temperature for a long time, and will fall off automatically when it reaches a certain quality. The material will flow out with the drying material, which will have a certain impact on the product quality. In this case, when cleaning the holes of the ventilation screen plate of the suspended material, it is necessary to stop the machine, disassemble the machine and clean it manually, so the production cost is relatively high. and has a greater impact on the mechanical
