It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A solid waste treatment sedimentation sludge drying bed provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Embodiment 1: Combination Figures 1 to 11 As shown, a solid waste treatment sedimentation sludge drying bed provided by the present invention includes a waste liquid release mechanism 100, a graded filter material mechanism 300 arranged on the waste liquid release mechanism 100, two groups of buoyancy components 200 arranged on the graded filter material mechanism 300, and a driving mechanism 400 arranged on the waste liquid release mechanism 100. The waste liquid release mechanism 100 is used to discharge rated waste liquid in solid and liquid, the buoyancy component 200 is used to provide passive lifting buoyancy to the graded filter material mechanism 300, the graded filter material mechanism 300 is used to actively control and drain the waste liquid in the solid waste, and the driving mechanism 400 is used to actively remove the dried solid material in the graded filter material mechanism 300 and prevent the occurrence of odor and dust.

[0025] The waste liquid release mechanism 100 includes a base 110 placed on the ground, two bases 130 installed inside the base 110, and a liquid discharge plate 120 installed inside the base 110, and the liquid discharge plate 120 is a triangular structure as a whole; The buoyancy assembly 200 includes a floating pad 210 installed at the bottom of the outer bin 311; The outer wall of the floating pad 210 is provided with evenly distributed hole grooves, and baffle plates 220 are arranged in the hole grooves; The baffle plate 220 is composed of a T-shaped sealing door and a gasket ring, and the T-shaped sealing door is adapted to penetrate into the interior of the drainage groove 140; The bottom of the base 130 is provided with evenly distributed drainage grooves 140; The grading filter media mechanism 300 includes two sets of resonance assemblies 310 arranged on the top of the base 110, two sets of feeding assemblies 320 arranged in the two sets of resonance assemblies 310, a second liquid baffle 370 and a constant pressure assembly 340 arranged outside the two sets of resonance assemblies 310, a pressure dividing plate 360 arranged on the constant pressure assembly 340, a slag screening assembly 330 arranged between the second liquid baffle 370 and the constant pressure assembly 340, a scraping member 380 arranged in the second liquid baffle 370, and an extended lead screw 390 arranged on the scraping member 380; The resonance assembly 310 includes an outer bin 311, a plurality of support plates 314 installed on the inner wall of the outer bin 311, a plurality of column heads 315 installed on the inclined arms of the inner cavity of the outer bin 311, a filter tank 312 installed inside the outer bin 311, and a filter screen 313 arranged inside the filter tank 312; A striker 319 is movably installed inside the support plate 314. The bottom end of the striker 319 is movably installed with a transfer member 318, and a crankshaft rod 316 is movably installed inside the transfer member 318. One end of the crankshaft rod 316 is installed with a runner 317; The inner wall of the outer bin 311 is provided with a chute; Both ends of the crankshaft rod 316 respectively penetrate into the second liquid baffle 370 and the constant pressure assembly 340.

[0026] When the solid waste materials are poured from the two feed bins 350 into the inner cavities of the two filter tanks 312, under the action of gravity, the waste liquid can pass through the filtration of the filter screen 313 and the filter tank 312 and transfer along the feeding assembly 320 into the slag screening assembly 330. Finally, the dregs in the waste liquid can be filtered for the third time by the hopper 331, and the filter residue will be actively stored by the hopper 331. The discharged waste liquid will enter the waste liquid release mechanism 100. As the waste liquid continues to increase, the two sets of buoyancy assemblies 200 will rise. Finally, the grading filter media mechanism 300 will rise as a whole. At this time, the excessive waste liquid can be effectively discharged outward along the drainage groove 140, and the solid materials remaining on the filter screen 313 can be effectively stored; When avoiding the interference of natural factors, the solid materials stored on the filter screen 313 can be dried bidirectionally. After the solid materials are effectively dried, the motor can be started. After the chain 450 is actively driven, the two drive shaft sleeves 460 will boost the extension screw rod 390 to contract into the waste liquid release mechanism 100. Finally, the scraping part 380 can horizontally push the solid materials on the top of the filter screen 313 towards the dividing pressure plate 360. During the horizontal pushing process, the vibration waves released by the outer bin 311 due to high-frequency impact can loosen the agglomerated solid materials. The dust-proof plate 335 covers the filter tank 312, which can avoid the spread of dust and peculiar smell during the removal of solid materials.

[0027] Embodiment 2: Combined with Figures 5 to 10 As shown, in the above embodiment, the constant pressure component 340 includes a first liquid baffle 341, four legs 342 fixedly installed on the outer wall of the first liquid baffle 341, and a compression spring 343 arranged outside the legs 342; The screen residue component 330 includes two partition plates 332 movably installed on the inner walls of the second liquid baffle 370 and the first liquid baffle 341, a hopper 331 installed between the two partition plates 332, a clamping plate 333 installed inside one of the partition plates 332, two first beam rods 334 installed in the two partition plates 332, and two dust-proof plates 335 movably installed outside the two first beam rods 334; A slideway is opened inside the dust-proof plate 335, and a second beam rod 336 is arranged in the slideway; Both ends of the second beam rod 336 are installed inside the tops of the second liquid baffle 370 and the first liquid baffle 341 respectively.

[0028] Preferably, the bottom end of the pull rod 440 is installed inside the clamping plate 333. When the feeding component 320 operates, the internal hydraulic sub-rod will drive the end plate 430 and the pull rod 440 to move up and down. The driven partition plates 332 and the hopper 331 can be lifted upward. At this time, the filter residues stored inside the hopper 331 can be naturally air-dried after being lifted upward. The two dust-proof plates 335 pushed upward will vertically turn over towards the tops of the two filter tanks 312. Finally, the filter tanks 312, the dust-proof plates 335, and the outer bin 311 can form a sealed cavity. When the scraping part 380 is horizontally pushed, the dry sludge on the top of the filter screen 313 can be horizontally pushed towards the dividing pressure plate 360 in the sealed cavity, thus effectively avoiding the problems of dust and peculiar smell during the removal of dry sludge.

[0029] Discharge trough openings are opened inside both the first liquid baffle 341 and the second liquid baffle 370, and two symmetrically distributed feed bins 350 are installed in the two trough openings at the top of the first liquid baffle 341; The grooves of the two feed bins 350 are respectively communicated with the inner cavities of the two filter tanks 312; The inner wall of the pressure distribution plate 360 is provided with symmetrically distributed convex pads, and the convex pads are adaptively clamped in the slots inside the first liquid baffle 341; The support legs 342 are adaptively penetrated to the outside of the pressure distribution plate 360, and one end of the compression spring 343 bears on the end of the outer end of the support leg 342, and the other end of the compression spring 343 bears on the outer wall of the pressure distribution plate 360.

[0030] Preferably, the second liquid baffle 370 and the first liquid baffle 341 are installed at both ends of the two outer bins 311, and the first liquid baffle 341 and the second liquid baffle 370 are fixed to both ends of the two outer bins 311 by welding. After the scraping member 380 pushes the sludge and applies pressure to the pressure distribution plate 360, the pressure distribution plate 360 elastically supported by the four compression springs 343 can evenly discharge the sludge; At the same time, after the pressure distribution plate 360 pressed by the four compression springs 343 fits with the first liquid baffle 341, the filter tank 312 in the shape of a pool, the second liquid baffle 370 and the first liquid baffle 341 can actively screen the dumped solid waste materials.

[0031] Example 3: Combined with Figures 8 to 10 As shown in the above figure, in the above embodiment, the feeding assembly 320 includes a sliding plate 321 movably installed in the inner wall chute of the hopper 331, a plurality of guide rods 322 movably installed in the inner wall plate of the sliding plate 321, a sloping plate 323 installed at the outer ends of the plurality of guide rods 322, and a spring 324 arranged outside the guide rods 322; One end of the spring 324 is connected to the inner wall of the sloping plate 323, and the other end of the spring 324 is connected to the plate on the inner wall of the sliding plate 321.

[0032] Preferably, the bottom end of the sloping plate 323 is located directly above the hopper 331, and the arc-shaped end face at the bottom end of the sloping plate 323 is adaptively fitted to the port at the top end of the hopper 331. After the hopper 331 filters the dregs in the waste liquid for the third time, the hopper 331 lifted upward will squeeze the two sloping plates 323 outward. Finally, the filter residue stored in the inner cavity of the hopper 331 can be naturally dried after being lifted upward; Moreover, the dirt falling on the slopes of the sloping plates 323 will also be blocked by the outer wall of the hopper 331. When the hopper 331 is reset, the dirt on the slopes of the two sloping plates 323 will be effectively transferred into the hopper 331. When the stock of the dregs on the ultrafiltration membrane in the inner cavity of the hopper 331 reaches a certain level, the ultrafiltration membrane can be replaced or washed to avoid the influence of the dirt on the removal of subsequent solid waste materials.

[0033] Example 4: Combined with Figures 4 to 11As shown in the above embodiment, the driving mechanism 400 includes a transmission component 410 installed on the outer wall of the second liquid baffle 370, a hydraulic component 420 arranged inside the transmission component 410, an end plate 430 installed on the hydraulic sub-rod inside the hydraulic component 420, a pull rod 440 installed at the other end of the end plate 430, two first brackets 470 installed on the outer wall of the second liquid baffle 370, and a second bracket 480 installed inside the first bracket 470; The transmission component 410 is composed of a chassis and an electric motor, and a gear is installed on the shaft of the electric motor, and a chain 450 is externally connected to the gear; Both ends of the chain 450 are connected to two drive shaft sleeves 460 in a transmission manner, and a transmission belt 490 is connected to the drive shaft sleeve 460 in a transmission manner; The drive shaft sleeve 460 is composed of an I-shaped shaft sleeve, a gear disc and a pulley combination, and a threaded hole adapted to the lengthened lead screw 390 is opened inside the I-shaped shaft sleeve.

[0034] Preferably, the transmission component 410 is fixedly installed on the outer wall of the second liquid baffle 370 through bolts, and two groups of clamps are installed on the inner wall of the chassis, and the hydraulic component 420 is fixed inside the two groups of clamps; The two first brackets 470 are fixedly installed on both sides of the outer wall of the second liquid baffle 370 by welding, and the two second brackets 480 are fixedly welded inside the first brackets 470, and the second bracket 480 is used to provide a sufficiently stable limit support for the lateral movement of the lengthened lead screw 390; Among them, the two drive shaft sleeves 460 are movably installed inside the two first brackets 470. When the electric motor runs, the bearings in the electric motor will drive the chain 450 through the gear. Finally, the two drive shaft sleeves 460 will boost the lengthened lead screw 390 to contract into the waste liquid release mechanism 100 during rotation. The scraping member 380 installed at the inner end of the lengthened lead screw 390 can actively scrape the dry sludge on the top of the filter screen 313. The runner 317 and the crankshaft rod 316 driven by the transmission belt 490 will drive a plurality of adapter parts 318 and a plurality of striker pins 319 to extend frequently. Finally, the striker pins 319 will strike the column head 315. At this time, the outer bin 311 and the filter tank 312 as a whole can loosen the caked sludge, so as to realize the rapid emptying of the dry sludge.

[0035] The working principle and usage process of the present invention: First, the hydraulic component 420 is operated. When the hydraulic sub-rod in the hydraulic component 420 contracts, the end plate 430 and the pull rod 440 installed at the top of the hydraulic sub-rod will push the slag screening component 330 and the combined hopper 331 and the two partition plates 332 down into the inner cavity of the waste liquid release mechanism 100. At this time, the two first beam rods 334 and the two dust-proof plates 335 pulled by the two partition plates 332 will be pressed and turn upwards from the top of the two filter tanks 312 until the two dust-proof plates 335 are vertically distributed; Next, the solid-liquid waste is transferred along the two feed bins 350 to the grooves of the two pre-installed filter ponds 312 and the filter screens 313. Since the top of the filter pond 312 is exposed, the solid-liquid materials under the action of gravity can be quickly screened by the filter screen 313. The liquid passing through the filter screen 313 will drip downward along the filter holes inside the filter pond 312, and the filtered liquid will be discharged along the inclined surface inside the outer bin 311. Finally, the dripping waste liquid will flow down along the top surface of the discharging assembly 320 and enter from the top of the hopper 331. The ultrafiltration membrane provided at the inner bottom of the hopper 331 can filter the waste liquid entering subsequently. As the waste liquid continues to be transferred to the inner cavity of the base 110, when the water level of the waste liquid rises, the two buoyancy assemblies 200 will be driven by the buoyancy force to drive the whole grading filter media mechanism 300 to rise until the baffle 220 rises from the inside of the drainage groove 140. At this time, the inner cavity of the base 110 can be released outward through the multiple drainage grooves 140 opened at the bottoms of the two pedestals 130, and the materials transferred to the grading filter media mechanism 300 in a fixed amount can be effectively separated into solid and liquid. The screened solid materials can be quickly dried under the blowing of the circuitous air flow and the natural air flow released in the inner cavity of the waste liquid discharging mechanism 100; When the solid materials are dried, operate the hydraulic sub-rod in the hydraulic component 420. Finally, the hydraulic sub-rod will push the end plate 430 and the pull rod 440 to rise, and the whole slag screening assembly 330 being pulled will be lifted upward. After the two evenly distributed dust-proof plates 335 are lifted upward, they will be vertically turned over under the pressure of the two second beam rods 336 until the two dust-proof plates 335 cover the tops of the two filter ponds 312; Next, operate the motor in the transmission assembly 410. As the gear at the outer end of the shaft of the motor rotates, the chain 450 driven actively will drive the two drive sleeves 460 to rotate at the same speed. At this time, the two drive sleeves 460 will boost the two lengthened lead screws 390. Finally, the scraping member 380 installed at the inner end of the lengthened lead screw 390 will move horizontally along the top surfaces of the two filter screens 313, so as to horizontally push the solid materials dried on the tops of the filter screens 313 towards the inside of the first liquid baffle 341. As the solid materials accumulate and squeeze the dividing pressure plate 360, the solid materials will effectively overflow from the notch inside the first liquid baffle 341. During the horizontal push of the scraping member 380, the two transmission belts 490 driven by the two drive sleeves 460 will drive the two rotating wheels 317. Finally, the rotating crankshaft rod 316 will drive a plurality of adapter members 318 and a plurality of impact pins 319 to lift up and down at a high frequency. At this time, the impact pins 319 will reciprocate up and down along the inside of the support plate 314, and the tops of the impact pins 319 will apply high-frequency impacts to the column heads 315. At this time, the outer bin 311 and the filter pond 312 can radiate the vibration force to the settled solid materials, and the solid materials that are horizontally pushed and resonate can be extruded from the gap between the dividing pressure plate 360 and the first liquid baffle 341; For the hopper 331 after rising, the filter residues stored therein can be quickly and naturally dried, and during the removal of solid materials, it is possible to avoid problems such as the overflow of solid materials due to vibration or the occurrence of abnormal odors.
