Description

Technical Field

[0001] The utility model relates to the field of wet material dispersing equipment, in particular to a wet material disperser of a drying unit. Background Art

[0002] In existing rotary drum dryers, wet material is fed via a belt conveyor to the dryer's feed pipe, where it enters the dryer. The dryer drum is a rotating cylinder slightly tilted to the horizontal. A heat carrier (such as hot air or flue gas) enters from the lower end, coming into countercurrent or cocurrent contact with the material. As the drum rotates, the material is pulled forward by gravity, directly contacting the heat carrier and drying the wet material. The dried material is then discharged from the discharge end via a belt conveyor or screw conveyor.

[0003] However, for some wet materials with very small particle size conveyed by the belt after the plate and frame filter press, the material viscosity is high. Materials with high viscosity are easy to form lumps or blocks, stick to the outer wall of the rotary drum dryer, and cannot be quickly dispersed into bulk materials, resulting in long heating time, increased equipment length, increased floor space, increased energy consumption, and for heat-sensitive materials, the local material temperature is too high, affecting product quality.

[0033] The surface of the umbrella-shaped rotating surface 32 is evenly distributed with a plurality of material holes. The diameters of the umbrella-shaped rotating surfaces 32 of the dispersion components 3 arranged sequentially from top to bottom increase in size, and the diameters of the feeding holes of the umbrella-shaped rotating surfaces 32 of the dispersion components 3 arranged sequentially from top to bottom decrease in size.

[0034] The upper joint 31 is coaxially arranged with the umbrella-shaped rotating surface 32 and is installed on the upper surface of the umbrella-shaped rotating surface 32;

[0035] The lower interface 33 is coaxially arranged with the umbrella-shaped rotating surface 32 and is installed at the bottom of the umbrella-shaped rotating surface 32. The lower interface 33 is detachably connected to the upper connector 31.

[0036] During use, when the wet material from the belt conveyor falls into the rotary drum dryer, the lumpy wet material with high viscosity falls on the umbrella-shaped rotating surface 32 under the action of gravity. The material holes on the multiple umbrella-shaped rotating surfaces 32 arranged from top to bottom can cooperate with gravity to cut the wet material into blocks. When it continues to fall, it is cut into smaller shapes. Driven by the motor 1, the transmission shaft 2 is driven to rotate. Under the action of centrifugal force, the lumpy wet material is quickly dispersed into various small balls and dispersed into the interior of the rotary drum dryer, fully contacting with hot air, etc. The present application can quickly disperse lumpy and large block wet materials into small lumps, fully increase the contact area between the material and the hot air, enhance the heat transfer effect, reduce the time required for drying, shorten the equipment length of the rotary drum dryer for processing such wet materials, reduce the occupied area, and improve the drying processing capacity. At the same time, the wet material disperser can also be suitable for processing heat-sensitive materials, thereby increasing the scope of use of the rotary drum dryer.

[0037] In this embodiment, the outer wall of the upper joint 31 has several protrusions, and a first connecting hole 34 is provided through the outer wall of the upper joint 31 near the top end, and a plug hole 35 corresponding to the upper joint 31 is provided at the bottom of the lower interface 33. The outer wall of the lower interface 33 is provided with multiple second connecting holes 36 at equal intervals along the vertical direction. Bolts pass through the first connecting holes 34 and the second connecting holes 36 in turn to connect the upper joint 31 and the lower interface 33 together. Under the action of the upper joint 31 and the lower interface 33, rapid assembly of multiple dispersed components 3 can be achieved, and a corresponding number of dispersed components 3 can be installed on the drive shaft 2 according to actual usage.

[0038] In this embodiment, the distance between adjacent dispersion components 3 is greater than 3.5 cm.

[0039] In this embodiment, a threaded connecting rod 37 is provided at the bottom of the upper joint 31, a through-hole corresponding to the threaded connecting rod 37 is provided on the umbrella-shaped rotating surface 32, and a threaded hole corresponding to the threaded connecting rod 37 is provided at the top of the lower joint 33. A plurality of limiting protrusions 38 are also provided at the bottom of the upper joint 31, and limiting holes corresponding to the limiting protrusions 38 are provided on the umbrella-shaped rotating surface 32.

[0040] When in use, the upper joint 31 and the lower interface 33 are threadedly connected to fix the umbrella-shaped rotating surface 32 inside, and at the same time realize the detachable installation of the umbrella-shaped rotating surface 32, which is convenient for replacing or repairing the umbrella-shaped rotating surface 32 after disassembly.

[0041] In this embodiment, the angle between the upper surface of the umbrella-shaped rotating surface 32 and the horizontal plane is 3-10 degrees.

[0042] The working principle of this utility model is as follows:

[0043] When the wet material from the belt conveyor falls into the rotary drum dryer, the lumpy wet material with high viscosity falls on the umbrella-shaped rotating surface 32 under the action of gravity. The material holes on the multiple umbrella-shaped rotating surfaces 32 arranged from top to bottom can cooperate with gravity to cut the wet material into blocks. When it continues to fall, it is cut into smaller shapes. Driven by the motor 1, the transmission shaft 2 is driven to rotate. Under the action of centrifugal force, the lumpy wet material is quickly dispersed into various small balls and dispersed into the interior of the rotary drum dryer, fully contacting with hot air, etc. The present application can quickly disperse lumpy and large block wet materials into small lumps, fully increase the contact area between the material and the hot air, enhance the heat transfer effect, reduce the time required for drying, shorten the equipment length of the rotary drum dryer for processing such wet materials, reduce the occupied area, and improve the drying processing capacity. At the same time, the wet material disperser can also be used to process heat-sensitive materials, increasing the scope of use of the rotary drum dryer.
