[0002] Sludge ceramsite is made from sludge as raw material, with the addition of auxiliary materials and fluxes, and is calcined through a certain process. Before preparing sludge ceramsite, the raw sludge is generally treated by processes such as concentration, dewatering, drying and grinding.

[0003] However, existing technologies still have some shortcomings in drying raw sludge:

[0004] When drying the dewatered raw sludge, since most of the dewatered raw sludge is in the form of lumps (or cakes) with a moisture content of about 20%, the existing technology mostly directly dries the lumpy raw sludge. Because the volume of a single raw sludge is large, the drying is insufficient. If sufficient drying is required, more drying time is needed, resulting in poor drying effect and low drying efficiency of the raw sludge. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-4As shown, this utility model provides a sludge drying device for preparing sludge ceramsite, including a preparation platform 1. A drying tank 11 is fixedly mounted on the upper surface of the preparation platform 1. A storage hopper 12 is fixedly mounted at one end of the drying tank 11. By setting the storage hopper 12, the blocky sludge to be dried can be stored in the storage hopper 12. Two guide plates 13 are fixedly mounted on the inner wall of the storage hopper 12. The two guide plates 13 are inclined and are used to guide the blocky sludge to flow. A discharge chute 14 is opened at the end of the drying tank 11 away from the storage hopper 12. A discharge hopper 15 is fixedly installed at one end of the storage hopper 12. The discharge hopper 15 is inclined and one end of the discharge hopper 15 corresponds to the discharge trough 14. By setting the discharge trough 14 and the discharge hopper 15, the dried block sludge can be discharged outward through the discharge trough 14 and the discharge hopper 15. A drying mechanism 2 is installed inside the drying tank 11, and a rotary cutting mechanism 4 is installed inside the storage hopper 12. By setting the drying mechanism 2 and the rotary cutting mechanism 4, the rotary cutting mechanism 4 can rotary cut the block sludge entering the drying tank 11 and chop the block sludge. The drying mechanism 2 can dry the chopped sludge evenly.

[0027] The drying mechanism 2 includes a heating fan 21 and an equipment plate 22. The heating fan 21 is fixedly mounted on the bottom wall of the drying tank 11, and the equipment plate 22 is slidably mounted on the bottom of the drying tank 11, located above the heating fan 21. The equipment plate 22 has several first air inlets 23. When the heating fan 21 operates, the high-temperature airflow generated can flow upwards through the first air inlets 23. The upper surface of the equipment plate 22 has an inclined surface 24, which is inclined towards the discharge trough 14. The sludge falling on the inclined surface 24 can move towards the discharge trough 14 and be discharged outwards through the discharge trough 14 and discharge hopper 15. A fixed column 25 is fixedly mounted on the upper surface of the equipment plate 22. Spiral blades 26 are fixedly mounted on the outer wall of the fixed column 25. The outer wall of the spiral blades 26 is in contact with the inner wall of the drying tank 11. By setting the spiral blades 26, the sludge to be dried in the storage hopper 12 can slide down along the spiral blades 26. The spiral blades 26 are provided with several No. 2 air inlets 27, which are spirally distributed on the spiral blades 26. By setting the No. 2 air inlets 27, the high-temperature airflow flowing upward through the No. 1 air inlet 23 can heat up the spiral blades 26 through the No. 2 air inlets 27, and at the same time, it can contact the sludge sliding down to dry the sludge. A spherical seat 28 is fixedly set at one end of the fixed column 25. By setting the spherical seat 28, the sludge falling into the drying tank 11 can be prevented from accumulating at the top of the fixed column 25. A number of exhaust troughs 29 are set at one end of the drying tank 11, which are spirally distributed on the drying tank 11. By setting the exhaust troughs 29, the high-temperature airflow flowing upward through the No. 2 air inlets 27 can be discharged outward through the exhaust troughs 29 for use in the drying operation.

[0028] A servo motor 3 is fixedly installed at the end of the drying tank 11 away from the storage hopper 12. A rotating rod 31 is fixedly installed at the drive output end of the servo motor 3. A cam 32 is fixedly installed at one end of the rotating rod 31. The cam 32 is located below the equipment disk 22. By turning on the servo motor 3, the drive shaft of the servo motor 3 can rotate the cam 32 through the rotating rod 31. The cam 32 can push the equipment disk 22 to move up and down reciprocally, thereby causing the spiral blades 26 and the downward sliding sludge to vibrate, preventing material jamming. Several telescopic guide rods 33 are fixedly installed on the bottom wall. The telescopic ends of the telescopic guide rods 33 are fixedly connected to the lower surface of the equipment disk 22. By setting the telescopic guide rods 33, the telescopic guide rods 33 can guide the equipment disk 22 in the vertical direction. When the cam 32 pushes the equipment disk 22 to rise vertically, the telescopic ends of the telescopic guide rods 33 extend. When the cam stops pushing the equipment disk 22 to rise vertically, the equipment disk 22, the fixed column 25 and the spiral blade 26 automatically descend under the action of the cam, and the telescopic ends of the telescopic guide rods 33 are forced to retract.

[0029] The rotary cutting mechanism 4 includes two rotating shafts 41, which are rotatably mounted inside the storage hopper 12. Rotating rollers 42 are fixedly mounted on each rotating shaft 41, and several blades 43 are fixedly mounted on each rotating roller 42. The blades 43 are positioned below the guide plate 13. By driving the two rotating shafts 41 to rotate synchronously in opposite directions, the two rotating shafts 41 can cause the two blades 43 to rotate synchronously in opposite directions via the two rotating rollers 42. The two synchronously rotating blades 43 can chop down falling lumpy sludge. A transmission gear 44 is fixedly mounted at one end of each rotating shaft 41, and the two transmission gears 44 mesh together. Next, by setting two transmission gears 44, the meshing of the two transmission gears 44 can keep the two rotating shafts 41 in a synchronous and opposite rotation state. The end of the rotating rod 31 near the servo motor 3 and the end of one of the rotating shafts 41 are both fixedly equipped with synchronous pulleys 45. A synchronous belt 46 is installed between the two synchronous pulleys 45. By setting the synchronous pulleys 45 and the synchronous belt 46, the synchronous pulleys 45 are toothed transmission pulleys and the synchronous belt 46 is a toothed transmission belt. The teeth of the two mesh, and when the rotating rod 31 rotates, the rotating rod 31 can make one of the rotating shafts 41 rotate synchronously in the same direction through the synchronous pulleys 45 and the synchronous belt 46.

[0030] Working principle: After the sludge dewatering treatment, the operator first turns on the heating fan 21. The high-temperature airflow generated by the heating fan 21 comes into contact with the spiral blades 26 after passing through the first air inlet 23, and then passes through the second air inlet 27, and is discharged outward from the exhaust duct 29 above. The high-temperature airflow heats up the spiral blades 26, preheating the drying tank 11 and the spiral blades 26.

[0031] Once the required temperature for sludge drying is reached, the operator adds the dewatered sludge into the storage hopper 12. The sludge in the storage hopper 12 is guided by two guide plates 13 and falls onto the blades 43. At this time, the operator turns on the servo motor 3. The drive shaft of the servo motor 3 causes the rotating rod 31 to rotate. The rotating rod 31 causes one of the rotating shafts 41 to rotate through two synchronous pulleys 45 and a synchronous belt 46. Under the action of two transmission gears 44, the two rotating shafts 41 rotate synchronously in opposite directions. The two rotating shafts 41 cause two sets of blades 43 (multiple blades 43 on one rotating roller 42 form a set) to rotate synchronously in opposite directions through two rotating rollers 42. The synchronous opposite rotation of the two sets of blades 43 cuts the sludge falling downwards.

[0032] The shredded sludge falls onto the top of the spiral blade 26 and slides down the spiral blade 26 onto the inclined surface 24 of the equipment plate 22. The sludge on the inclined surface 24 is discharged outward through the discharge chute 14 and the discharge hopper 15.

[0033] During this process, the high-temperature airflow comes into contact with the sludge falling downwards. The heated drying tank 11 and the spiral blades 26 work together to dry the sludge. At the same time, the rotating rod 31 causes the cam 32 to rotate, and the cam 32 causes the equipment disk 22, the fixed column 25 and the spiral blades 26 to move up and down repeatedly, causing the falling sludge to vibrate and avoid jamming. This facilitates the uniform drying of the sludge, thereby effectively improving the drying effect and efficiency of the sludge. In addition, the sludge is shredded in advance, which improves the efficiency of subsequent sludge grinding.

[0034] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
