Referring to fig. 1, the hydraulic garbage sorting device provided by the embodiment of the invention is used for sorting household garbage and construction garbage formed in slurry in river and lake dredging engineering. The garbage hydraulic sorting equipment comprises a slurry conveying pipeline 1, a storage hopper device 2 and a stirring power device 3:
The slurry conveying pipeline 1 comprises an incoming pipeline 11, a sorting pipeline 12 and a discharging pipeline 13, wherein the sorting pipeline 12 is in a vertical state, the incoming pipeline 11 is communicated with the sorting pipeline 12, the discharging pipeline 13 is communicated with the sorting pipeline 12, and the discharging pipeline 13 and the incoming pipeline 11 are sequentially distributed up and down along the axial direction of the sorting pipeline 12;
The stirring power device 3 is arranged in the sorting pipeline 12 so that the slurry containing the household garbage passes through the sorting pipeline 12 and enters the discharging pipeline 13;
The storage hopper device 2 is arranged at the bottom end part of the sorting pipeline 12 along the axis of the sorting pipeline 12 and is communicated with the sorting pipeline 12, and the construction waste in the slurry falls into the storage hopper device 2.
The hydraulic garbage sorting equipment provided by the embodiment of the invention has the following working process: the slurry incoming material containing the household garbage and the construction garbage enters from an incoming material pipeline 11, flows into a sorting pipeline 12 and flows out from a discharging pipeline 13. Due to the height difference between the feeding pipeline 11 and the discharging pipeline 13, under the action of gravity, the construction waste with high density is separated from the slurry in the flowing process along with the slurry and falls into the storage hopper device 2, while the domestic waste with low density is discharged from the discharging pipeline 13 along with the slurry under the driving action of the stirring power device 3. Thus, not only can the household garbage and the construction garbage in the slurry be effectively separated, but also the separation efficiency is high.
Referring to fig. 1, in the present embodiment, the stirring power device 3 includes a stirring head 31, a connecting rod 32, and a driving motor 33. One end of the connecting rod 32 is connected to a main shaft of the driving motor 33, the other end of the connecting rod 32 is connected to the stirring head 31, and the stirring head 31 and the connecting rod 32 penetrate into the sorting pipeline 12 from the top end of the sorting pipeline 12. The stirring head 31 rotates around the axis of the connecting rod 32 under the drive of the driving motor 33, so that rotational flow lifting force is generated, and slurry passes through the sorting pipeline 12 in a vertical state and then enters the discharging pipeline 13.
Preferably, referring to fig. 1, in the present embodiment, a stirring head 31 is disposed at the communication position between the feeding pipe 11 and the sorting pipe 12. That is, once the slurry enters the separation pipeline 12, the slurry is subjected to cyclone rising and flows out from the separation pipeline 12 to the discharge pipeline 13, and meanwhile, the construction waste is separated from the slurry and falls into the storage hopper device 2, so that the separation effect is good.
Referring to fig. 1, in the present embodiment, the storage hopper device 2 includes a baffle 21 and a storage compartment 22, the open end of the storage compartment 22 faces the sorting duct 12 and is in communication with the sorting duct 12, and the baffle 21 is interposed between the sorting duct 12 and the storage compartment 22 and is movable in the radial direction of the sorting duct 12 to communicate or isolate the sorting duct 12 from the storage compartment 22. When sorting work is performed, the separation baffle 21 is opened along the radial direction of the sorting pipeline 12 so that the sorting pipeline 12 is communicated with the storage cabin 22, the construction waste falls into the storage cabin 22 until the storage cabin 22 is full, the separation baffle 21 is closed along the radial direction of the sorting pipeline 12 so that the sorting pipeline 12 is isolated from the storage cabin 22, and then the construction waste in the storage cabin 22 is removed to enter a sorting period.
Preferably, referring to fig. 1, the sorting duct 12 includes a main body pipe section 121 and a temporary storage pipe section 122, and the material feeding duct 11 separates the main body pipe section 121 and the temporary storage pipe section 122 at both sides thereof, and the temporary storage pipe section 122 is in communication with the storage compartment 22. When the storage cabin 22 is filled with construction waste, the separation plate 21 is inserted into the sorting pipeline 12 along the radial direction to isolate the temporary storage pipe section 122 from the storage cabin 22, at this time, sorting work can still be continued, construction waste with higher density is separated from mud and temporarily stored in the temporary storage pipe section 122 until the storage cabin 22 finishes discharging, and the separation plate 21 is opened again to enable the construction waste in the temporary storage pipeline to fall into the storage cabin 22, so that the sorting work is not needed to be suspended in the discharging process, and the sorting efficiency is higher.
Referring to fig. 1, in the present embodiment, the storage cabin 22 includes a cabin body 221 having a hollow tubular structure and a stripper plate 222, wherein the stripper plate 222 and the baffle 21 are disposed at two ends of the cabin body 221, and the stripper plate 222 is movably connected to the cabin body 221 and can be plugged into the cabin body 221. Specifically, one end of the stripper plate 222 is pivotally connected to the end of the bin 221, so that when unloading is required, the stripper plate 222 is turned to open, so that construction waste falls out of the bin 221, and after unloading is completed, the stripper plate 222 is plugged at the end of the bin 221.
Preferably, referring to fig. 1, in order to facilitate the observation of the storage of the construction waste in the cabin 221, an observation window 223 is provided in the cabin 221.
Preferably, referring to fig. 1, the cabin 221 is further provided with a slurry outlet 224. In the sorting process, the slurry inevitably enters the cabin 221, and in order to reduce the pressure of the cabin 221, the slurry discharge outlet 224 can be opened before discharging, so that the slurry in the cabin 221 flows out, thereby reducing the internal pressure of the cabin 221 and facilitating the opening of the discharge plate 222.
Referring to fig. 1 and 2, in the present embodiment, an open structure 211 for mud to pass through is formed on the baffle plate 21. When the one-time sorting cycle is completed, the temporary storage pipeline is blocked by closing the baffle plate 21, the open pore structure 211 can discharge mud falling into the temporary storage pipeline, and meanwhile, the baffle plate is prevented from being excessively pressed, so that the temporary storage pipeline can be smoothly pulled out again.
Further, referring to fig. 1, in this embodiment, the hydraulic garbage sorting apparatus further includes a pump body 4, and the pump body 4 is disposed on the discharge pipe 13. The pump body 4 is used for accelerating the outflow speed of the slurry from the discharge pipeline 13 and avoiding the slurry from flowing back into the sorting pipeline 12.
Further, referring to fig. 1, in this embodiment, the hydraulic garbage sorting apparatus further includes a grid plate 5, where the grid plate 5 is disposed at an outlet of the discharging pipeline 13. And the grid net plate 5 is utilized to carry out secondary separation on the slurry, so that the construction waste with smaller volume is prevented from being mixed in the slurry.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
