Description

Technical Field

[0001] The invention relates to the technical field of fluidized beds, and in particular to a fluidized bed for processing powdered foods. Background Art

[0002] Fluidized bed dryer, also known as vibrating fluidized bed, is a new type of fluidized high-efficiency drying equipment suitable for drying granular and powdered materials. It has the advantages of easy operation, energy saving and environmental protection. Vibrating fluidized bed is a new type of equipment that has been gradually developed and expanded in the past decade. It is becoming the main type of drying equipment. Vibrating fluidized bed is a new type of drying device that applies a vibration source with specific requirements to an ordinary fluidized bed dryer.

[0003] At present, the fluidized bed puts the powder onto the fluidized bed plate for drying. The fluidized bed plate is usually set as a porous sieve plate. Hot air is blown in from the bottom of the porous sieve plate and then discharged from the top. The moisture in the powder is dried out by the dry wind. However, due to the high humidity of some powders inside, some powders with high humidity will adhere to the mesh of the sieve, resulting in the inability of the local airflow to flow, resulting in a channeling effect, resulting in a reduction in the drying effect of the powder. At present, the wind force is increased for processing, but some powders with high humidity will be stuck in the mesh of the sieve, with a high degree of adhesion and unable to be cleaned. At this time, the fluidized bed needs to be shut down and then disassembled for manual processing of the sieve. The sieve cannot be automatically cleaned, resulting in poor stability when the fluidized bed is drying the powder, and at the same time leads to low processing efficiency. Summary of the invention

[0023] (1) The mounting plate is driven to move by a moving mechanism, and the mounting plate drives the cleaning tube to move at the same time.

Then, the air flow sensor in the air inlet hood mechanically determines the flow rate of the drying gas at each position, and locates the position where the adhesion and blockage occur on the screen plate. When the fluidized bed is drying the powder, the position where the channel flow occurs can be automatically found and located, so as to facilitate timely processing of the position where the channel flow occurs.

[0024] (2) The cleaning tube and the receiving barrel are driven by a moving mechanism to move to a position where channel flow is generated, and then the position of the screen is sealed by the cleaning tube and the receiving barrel. Then, the cleaning and drying mechanism in the cleaning tube and the recovery mechanism in the receiving barrel cooperate with each other, thereby achieving the solution efficiency of the channel flow problem without stopping the fluidized bed. At the same time, there is no need to stop the machine for cleaning, which further improves the stability of fluidized bed production.

[0025] (3) At the same time, when drying powder with high humidity, the cleaning tube is driven by the moving mechanism to move back and forth at the initial end of the fluidized bed for drying the powder, and then the cleaning brush in the cleaning tube is driven to move downward and rotate at the same time, so that the cleaning brush is inserted into the powder, so that the cleaning brush can puncture the generated bubbles in time, so that the bubbles can be punctured in time when they are small, thereby greatly reducing the influence of bubbles on drying and improving the fluidized bed drying effect.

The bottom of the return box 61 is fixedly connected to a discharge pipe, and a solenoid valve is arranged on the discharge pipe. The side of the material receiving barrel 12 opposite to the cleaning pipe 11 is fixedly connected to a rubber sealing gasket 291.

[0045] When channel flow occurs in the fluidized bed, the mounting plate 3 and the cleaning tube 11 are moved by the moving mechanism, and the cleaning tube 11 drives the first connecting plate 13 and the air inlet hood 16 to move. At this time, the air inlet hood 16 moves above the fluidized bed sieve plate. At this time, the hot air dried in the fluidized bed flows upward, and then the airflow passes through the air inlet hood 16 and enters the airflow sensor 17. Then the airflow sensor 17 is started. The airflow sensor 17 is a prior art and can detect the airflow flowing in the pipeline, so it will not be described in detail here. At the same time, the airflow sensor 17 is connected to the single-chip microcomputer. When the airflow entering the air inlet hood 16 becomes smaller and an abnormality occurs, the moving mechanism is controlled to stop moving, and then the mounting plate 3 and the cleaning tube 11 are driven downward by the moving mechanism. The first electric telescopic rod 27 drives the connecting ring 26 and the transmission pipe 24 to move downward, and the transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to move downward. At the same time, the installation pipe 22 is driven to rotate through the transmission mechanism, and the transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to rotate. The cleaning brush 29 cleans the powder adhering to the sieve plate at that location. After cleaning, the transmission pipe 24 is driven to move upward, and then the airflow entering the air inlet cover 16 is detected by the airflow sensor 17. If the airflow is unobstructed, the powder adhering thereto is cleaned out, and the mesh is not blocked. When the airflow is still not smooth, the mesh of the sieve plate is blocked, the airflow cannot pass through, and a channel flow occurs, so that the fluidized bed can automatically detect the position where the channel flow occurs when drying the powder. The cleaning tube 12 is moved to the bottom of the corresponding position through the moving mechanism at the bottom of the installation frame 2, and then the collecting tube 12 is driven to move upward, and at the same time, the cleaning tube 12 is driven to move downward. At the same time, the transmission tube 24 is driven to rotate while the transmission tube 24 drives the water outlet pipe 28 and the cleaning brush 29 to rotate, and at the same time, the cleaning tube 11 is driven to move, and the powder at this position is cleaned out, and then the cleaning tube 11 and the collecting tube 12 are driven to press against the sieve plate on the fluidized bed, and at the same time, they are sealed by the rubber sealing gasket 291, and then the transmission tube 24 is driven to rotate, and the transmission tube 24 drives the water outlet pipe 28 to rotate, and the water outlet pipe 28 drives the cleaning brush 29 to rotate, and at the same time, the water is pumped into the fluidized bed through the first water pump 53. The water in the box 54 is supplied to the transmission pipe 24 through the first connecting pipe 51, the second connecting pipe 52 and the hose. Then the transmission pipe 24 passes the water into the water spray pipe 290 through the water outlet pipe 28. Then the water spray pipe 290 drives the baffle 31 to rotate under the action of water pressure, and the second spring 32 is stretched. Then the water is sprayed through the water spray pipe 290 to wash the sieve plate. At the same time, the water outlet pipe 28 and the cleaning brush 29 are driven to rotate, and the cleaning brush 29 is brushed to wash away the powder adhering to the mesh of the sieve. During this cleaning process, since the fluidized bed continues to work, the sieve plate vibrates up and down. At this time, the outer surfaces of the cleaning pipe 11 and the receiving barrel 12 are under the telescopic buffering action of the telescopic rod 14 and the first spring 15.Slide up and down on the mounting plate 3 to buffer the vibration. At the same time, the cleaning tube 11 and the collecting barrel 12 are tightly pressed against the sieve plate under the force of the telescopic rod 14, and the rubber sealing gasket is used for sealing. Under the action of pressure, the rubber sealing gasket will be squeezed into the mesh of the sieve plate to prevent water from moving out. Then, the powder in the mesh of the sieve plate is fully cleaned by brushing with the cleaning brush 29 and flushing with the water spray pipe 290. At the same time, the cleaning water passes through the mesh and falls into the collecting barrel 12. Then, the sewage after flushing is pumped into the return box 61 for collection through the second water pump 62 and the hose. After cleaning, Then, the electromagnetic valve on the hose of the hot blower 55 is started, and the hot air is then passed into the transmission pipe 24 through the hose through the hot blower 55, and then the transmission pipe 24 sprays the hot air through the water outlet pipe 28 and the water spray pipe 290. At this time, the baffle 31 rotates and opens under the action of wind force, and then drives the water outlet pipe 28 to rotate, so as to achieve rapid drying of the sieve plate at the cleaning position, which is convenient for subsequent drying of the powder, thereby achieving rapid cleaning and drying of the position where the sieve plate adheres to the powder and generates channeling, greatly improving the efficiency of solving the channeling problem, and at the same time, there is no need to stop the machine for cleaning, which further improves the stability of fluidizer production.

[0046] At the same time, when drying powder with high humidity during use, a large number of bubbles will be generated in the fluidized bed drying. This is because too much water will form a liquid film on the surface of the particles, causing some cracks on the surface of the particles, thereby forming bubbles. If the generated bubbles are not handled in time, the contact area between the drying gas and the powder will be small, resulting in poor drying effect. Too many bubbles in the fluidized bed dryer will increase the vibration and noise of the equipment, affecting the stability of the equipment. In serious cases, it will also cause equipment failure. At this time, the cleaning pipe 11 is driven by the moving mechanism to move the initial drying section of the fluidized bed material, and then the transmission pipe 24 is driven downward by the first electric telescopic rod 27. The transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to move downward, so that the cleaning brush 29 is inserted into the surface of the dry powder, and at the same time drives the transmission pipe 24 to rotate, thereby driving the cleaning brush 29 to rotate. At the same time, the moving mechanism drives the mounting plate 3 and the cleaning pipe 11 to move, so that the cleaning brush 29 can timely puncture the generated bubbles, so that the bubbles are timely punctured when they are small, greatly reducing the influence of bubbles on drying and improving the fluidized bed drying effect.

[0050] The working principle of the present invention is as follows: the mounting plate is driven to move by a moving mechanism, and the mounting plate 3 drives the cleaning and disturbance mechanism to move, and then the cleaning and disturbance mechanism scans and detects the airflow at each position in the fluidized bed, so that it detects the position where the channel flow is generated, and realizes automatic detection and positioning of the position where the channel flow is generated.
