Definitions
- the present invention relates to a radial rotary drying apparatus for multipurpose drying such as sewage sludge or food waste.
- Single rotary (kiln) or three-stage rotary drying equipment is a technology for industrial drying equipment which is widely used for sludge, food waste or various multipurpose drying.
- Wet sludge has a water content of 80% and once passed through the drying unit, the sludge dry rate is less than 10%.
- Three-stage rotary dryer is 1.5 times more efficient than single rotary dryer.
- the three-stage rotary drying unit was first patented in the United States in 1984 [1].
- Several companies in the United States (Vincent Co., Stela Co.) have developed and used a three-stage rotary drying device to dry food or coffee.
- three-stage rotary drying equipment has been used for sewage sludge drying (eg, ANDRITZ Co., Austria).
- the lowering of the drying efficiency and the lowering of the flow rate in the 2-3 stage drum make it difficult to maintain a proper moisture content.
- the sludge flow space in the drum is relatively narrow, and sludge agglomerates often cause clogging.
- the existing three-stage rotary drying unit cannot be used. To reduce this blockage, the outer diameter of the drum must be increased. Large diameter three-stage rotary dryers have a large footprint, energy inefficiency and operational hazards.
- the present invention aims to provide a new concept radial rotary drying apparatus that improves the disadvantages of the existing three-stage rotary drying apparatus.
- the hot air and the dry matter put into the inner drum are dried while sequentially moving radially separated spaces and discharged again through the inner drum. Its large radial flow space is useful for drying relatively large items, and prevents clogging of drums and maximizes drying efficiency, while continuously drying large volumes of objects without excessively increasing the diameter or length of the device. To be handled.
- the dried material is crushed during drying to further improve the drying efficiency.
- the present invention is a radial rotary drying apparatus used in various industries, the outer drum 201, the inner drum 202, the outer drum 201 located inside the outer drum 201 ) And a radial plate 203 radially positioned between the inner drum 202, a lift plate 204 attached to one surface of the radial plate 203, and drum inlet-side plates positioned at both ends of the outer drum 201 ( 210 and the drum outlet-side plate 211, the outer drum 201, the inner drum 202, the spinning plate 203, the drum inlet-side plate 210 and the drum outlet-side plate 211
- the drum 200, which forms a radial flow space 208, and the inner drum 202 is one of the plurality of radial flow space 208, the drum inlet 230, which is to be introduced, the incoming dry Spin-drying inlet 206, through which a plurality of radial flow spaces 208 are passed, and a spin-drying outlet 20 into which the dried items are fed
- the drum 200 may further include a hammer 301 fixed to the other surface of the radiating plate 203 by an axis.
- FIG. 1 is a perspective view of a radial rotary drying apparatus of the present invention
- FIG. 3 is a drying principle diagram of the radial rotary drum of the present invention.
- FIG. 4 is a cross-sectional view of the radial rotary drum having the function of shredding the object.
- the present invention relates to a radial rotary drying apparatus for multi-purpose drying, such as sewage sludge or food waste.
- the radial rotary dryer is suitable for drying the bulky objects compared to the conventional three stage rotary dryer.
- FIG. 1 shows a perspective view of the device.
- the radial rotary drying apparatus is a radial drum 200, a frame 100, a burner 225 for supplying hot air air to the radial drum 200, and a dry object input transport device for supplying a dry object to the radial drum 200. ).
- the radial drum 200 is supported on the frame 100 by the drum bearing 250 and the roller bearing 251.
- the dry matter injected into the dry matter inlet 224 is introduced into the radial drum 200 together with the hot air air supplied from the burner 225 after passing through the dry matter injecting and transporting device 223.
- FIG. 2 shows an axial cross-sectional view of the radial rotary drum 200
- Figure 3 shows the radial rotary drum 200 with the outer drum 201 removed for convenience of description.
- the drum 200 is radially disposed between the outer drum 201, the inner drum 202 located inside the outer drum 201, and the outer drum 201 and the inner drum 202.
- Radiating plate 203 located in the direction, the lift plate 204 attached to one surface (rotation direction 209 surface) of the radiation plate 203, drum inlet-side plate 210 located in the inlet direction of the outer drum 201 ),
- a drum outlet-side plate 211 positioned in the outlet direction of the outer drum 201 and a driven-sprocket 220 for rotating the drum 200.
- the outer drum 201, the inner drum 202, the spin plate 203, the drum inlet-side plate 210 and the drum outlet-side plate 211 form a plurality of radial drying spaces 208.
- the driven sprocket 220 and the drum 200 are rotated in the direction of the arrow by the driving motor 222 fixed to the frame 100 and the driving sprocket 221 directly connected to the driving motor.
- the drum 200 rotates, the dried object introduced therein is dried while being mixed by the lift plate 204 in each drying space 208 separated by the spin plate 203.
- the object to be dried is dried while moving each drying space 208 in a direction opposite to the rotation direction 209 of the drum.
- Figure 3 shows the position of the object to be dried according to the rotation of the drum (rotation angle 0 degrees, 180 degrees, 310 degrees) to illustrate in more detail the drying principle of the radial rotary drum 200 of the present invention.
- the dry item is introduced into the inner drum 202 together with the hot air through the drum inlet 230. Due to the rotation of the drum 200, the object to be dried is moved to the drying space 208 through the spinning drying inlet 206 of the inner drum 202. In the drying space 208 is mixed by the lift plate 204 and dried, gradually moving in the direction of the arrow of Figure 3 ('209' of Figure 2).
- the dried product passing through the plurality of drying spaces 208 passes through the radiation drying outlet 207 of the inner drum 202 and is discharged to the drum outlet 231.
- the lift plate 204 is installed to be inclined in the rotation axis direction so that the object to be dried is automatically moved by the rotation of the drum 200 to be discharged to the drum outlet 231.
- the separating plate 205 is attached to the center of the inner drum 202 to prevent the dry matter and hot air introduced through the drum inlet 230 to proceed directly to the drum outlet 231.
- Figure 4 shows another embodiment of the present invention.
- long hammers 301a to 301g in the axial direction on the rear surface of the radiation plate 203 in the inside of the radial rotary drum 200 (that is, the back surface to which the lift plate 204 is attached). Attached to allow the dried material to be pulverized by free fall of the hammers 301a to 301g according to the rotation of the drum 200.
- the central axis of rotation 302 of the hammers 301a to 301g is fixed to the radiating plate 203.
- Fig. 4 shows the positions of the hammers 301a to 301g according to the rotation angle of the drum 200 on the fixed roller bearing 251.
- the hammer 301g freely falls to the position of the hammer 301a in accordance with the rotation of the drum 200 to impact the object to be pulverized.
