The use method of the dredging fertilizer making equipment comprises the following steps:
s1, the
s2, controlling the first
s3, before the dewatered sludge enters the stirring
The working principle of the invention is as follows: when the device works, the support 1, the dredging mechanism, the dewatering mechanism and the fertilizer making mechanism are installed and erected, firstly, the driving mechanism is controlled to work to enable the sliding sleeve 2 to slide to a specified position along the support 1, then, the traction mechanism is controlled to work to enable the steel wire ropes 3 to be released, so that the grab buckets 5 are driven to descend through the sleeve 4, the grab buckets 5 are enabled to descend to the sludge position of a river channel, then, the first hydraulic cylinder 22 is controlled to extend, the movable plate 24 moves downwards, the movable plate 24 enables the opened grab buckets 5 to be close to each other and folded through the movable rod 6, so that the sludge is grabbed into the two groups of grab buckets 5, then, the traction mechanism is controlled to work to enable the steel wire ropes 3 to be wound, the grab buckets 5 move upwards through the sleeve 4 and the driving mechanism enables the grab buckets 5 to horizontally move through the sliding sleeve 2, so that the grab buckets 5 filled with the sludge are positioned right above the feeding hopper 7, in addition, when the grab bucket 5 enters the water in the river channel, water can be discharged from the grab bucket 5 through the water discharge hole 20, the resistance of the grab bucket 5 in cleaning sludge underwater is reduced, the grab bucket is lifted up to the water surface from the water after the sludge is cleaned, the water discharge hole 20 also plays a role in cleaning the sludge in the grab bucket 5, the working time and the working load of a later-stage dewatering mechanism are reduced, and the sludge in the river channel can be shoveled and excavated by the arranged scraper 21, so that the sludge cleaning efficiency is greatly improved;
controlling the first hydraulic cylinder 22 to contract to enable the moving plate 24 to move upwards, enabling the moving plate 24 to open the closed grab bucket 5 through the moving rod 6 to enable sludge in the grab bucket 5 to fall into the charging hopper 7, then controlling the driving motor to work to drive the driving shaft 28 and the driving gear 29 on the driving shaft 28 to rotate, enabling the driving gear 29 to drive the driven gear 30 to rotate through meshing action to enable the rotary drum 8 to rotate, enabling moisture in the sludge to be discharged through the filtering holes 31 on the rotary drum 8, controlling the humidity sensor 32 on the rotary drum 8 to monitor the moisture content in the sludge, controlling the second hydraulic cylinder 26 to work when the moisture content in the sludge reaches a process standard to enable the moving plate 27 to be lifted on one side close to the sludge cleaning mechanism to enable the rotary drum 8 to incline towards the fertilizer making mechanism, and enabling the dewatered sludge to enter the stirring tank 17 along the connecting pipe 11, the feeding hopper 12 and the feeding pipe 13 in sequence, the humidity sensor 32 on the rotary drum 8 is used for monitoring the moisture content in the sludge, so that the automation degree of the dehydration mechanism is high, the operation is convenient, the dehydration effect is good, the moisture content in the sludge can be controlled, the effect of preparing fertilizer from the sludge in the later period is facilitated, and the quality of the fertilizer finished product is improved;
before the dewatered sludge enters the stirring tank 17, the feeding pipe 15 is respectively communicated with the strain feeding tank, bacterial liquid is quantitatively added into the stirring tank 17 through a pump body of the strain feeding pipe, the air pipe 14 is communicated with the air tank, oxygen is quantitatively added into the stirring tank 17 through the air pump, after the dewatered sludge enters the stirring tank 17, the motor 33 is started to work to drive the stirring shaft 35 to rotate, so that the stirring shaft 35 drives the shovel blade 38 on the second connecting plate 37 to rotate along the inner wall of the stirring cavity 34 through the first connecting plate 36 and the second connecting plate 37, the sludge in the stirring cavity 34 is overturned, the bacterial liquid and the oxygen can be fully and uniformly contacted with the dewatered sludge, the fertilizer preparation efficiency of the sludge is improved, the product connecting shaft quality of the sludge fertilizer preparation is improved, and simultaneously, under the matching action of the first connecting plate 36, the second connecting plate 37, the shovel blades 38, 39 and the torsion spring 40, make silt mix with fungus liquid and oxygen intensive mixing respectively, and shovel sword 38 can avoid the silt adhesion on the inner wall of stirring chamber 34, make the silt stirring evenly enough lead to the problem that system fertile inefficiency, and when carrying out the unloading after the system fertile completion, shovel sword 38 can make the convenient unloading of fertilizer, and also there is not remaining on the inner wall, after the fermentation of silt is accomplished, open the valve on the discharge tube 16, make the silt after the fermentation is accomplished pack through hopper 18 discharge down, can stir system fertile in-process through filling tube 15 and the trachea 14 that sets up in addition, can be in the working process of system fertile, conveniently supply it, from not influencing the continuity of system fertile work.
