Description

Technical Field

[0001] This invention relates to the field of sludge drying bed technology, specifically a sludge drying bed for solid waste treatment. Background Technology

[0002] Sludge drying beds are important equipment in the sludge treatment process. They are mainly used to effectively remove moisture from sludge, thereby reducing, stabilizing, and rendering the sludge harmless.

[0003] The sludge drying bed consists of multiple components. The drying chamber (bed body) is mainly used to settle sludge in solid waste until the settled sludge is dried. However, in order to meet the settling and drying requirements of sludge in large quantities of solid waste, the volume requirement of the drying chamber is correspondingly increased. However, with the settling and increasing thickness of the sludge, it is difficult to control the moisture inside the sludge in a timely and effective manner. In severe cases, fermentation will occur in the damp part of the sludge, which will then produce an odor.

[0004] In view of this, a solid waste treatment sedimentation sludge drying bed was designed to solve the above problems. Summary of the Invention

[0031] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0032] 1. This invention transforms the existing large-volume drying bed of concrete structure into a small-volume, easily installed indoor graded filter media mechanism for controlling the drying of sludge. When solid waste is poured into two volumes of two sets of resonant components, the waste liquid in the solid waste can be actively controlled to dry under gravity. The sludge after being controlled to dry can then be rapidly dried under the combined action of natural wind and the return gas in the cavity of the graded filter media mechanism. This effectively improves the drying efficiency of settled sludge, shortens the sludge drying time, and reduces the interference of external climatic factors.

[0033] 2. This invention uses two sets of resonant components to actively drain the waste liquid from the solid waste material. The waste liquid then undergoes a third filtration process through a slag screening component. As the waste liquid enters the waste liquid release mechanism, the two sets of buoyancy components actively lift the graded filter media mechanism upwards. This process continuously and actively filters the input solid waste, preventing the continuous increase of waste liquid from causing secondary backflushing interference to the settled sludge, thus improving the treatment efficiency of the solid waste material.

[0034] 3. This invention installs two symmetrically distributed first beams on the top of two partitions. Two dustproof plates movably installed on the two beams can seal the top of the dried filter tank. When the dried sludge in the filter tank needs to be removed, the drive mechanism can actively push the extended screw and scraper to actively scrape off the dried sludge in the filter tank. With the resonance radiation of the resonance component on the dried sludge, the sludge can be effectively squeezed out from the gap between the first baffle plate and the pressure plate, thereby avoiding the problem of dust or odor during the sludge drying and removal process.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0052] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0053] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a solid waste treatment sedimentation sludge drying bed.

[0054] Example 1:

[0055] Combination Figures 1 to 11As shown, the present invention provides a solid waste treatment sedimentation sludge drying bed, including a waste liquid release mechanism 100, a grading filter media mechanism 300 disposed on the waste liquid release mechanism 100, two sets of buoyancy components 200 disposed on the grading filter media mechanism 300, and a drive mechanism 400 disposed on the waste liquid release mechanism 100. The waste liquid release mechanism 100 is used to discharge a rated amount of waste liquid in the solid-liquid mixture. The buoyancy components 200 are used to provide passive lifting buoyancy to the grading filter media mechanism 300. The grading filter media mechanism 300 is used to actively control and drain the waste liquid in the solid waste. The drive mechanism 400 is used to actively remove the dried solid material in the grading filter media mechanism 300 and prevent odor and dust from occurring.

[0056] The waste liquid release mechanism 100 includes a base 110 placed on the ground, two bases 130 installed inside the base 110, and a drain plate 120 installed inside the base 110, and the drain plate 120 is in the shape of a triangular structure.

[0057] The buoyancy assembly 200 includes a float 210 mounted on the bottom of the outer compartment 311;

[0058] The outer wall of the floating pad 210 is provided with evenly distributed holes and grooves, and baffles 220 are provided in the holes and grooves.

[0059] The baffle 220 consists of a T-shaped sealing door and a gasket, and the T-shaped sealing door is adapted to penetrate into the interior of the drainage channel 140;

[0060] The bottom of the base 130 is provided with evenly distributed drainage grooves 140;

[0061] The grading filter media mechanism 300 includes two sets of resonant components 310 disposed on the top of the base 110, two sets of discharge components 320 disposed within the two sets of resonant components 310, a second baffle plate 370 and a pressure regulating component 340 disposed outside the two sets of resonant components 310, a pressure dividing plate 360 ​​disposed on the pressure regulating component 340, a slag screening component 330 disposed between the second baffle plate 370 and the pressure regulating component 340, a scraper 380 disposed within the second baffle plate 370, and an extended screw 390 disposed on the scraper 380.

[0062] The resonant assembly 310 includes an outer chamber 311, multiple trays 314 mounted on the inner wall of the outer chamber 311, multiple column heads 315 mounted on the inclined arm of the inner cavity of the outer chamber 311, a filter pool 312 mounted on the inner side of the outer chamber 311, and a filter screen 313 disposed on the inner side of the filter pool 312.

[0063] A striker 319 is movably installed inside the tray 314. A connector 318 is movably installed at the bottom end of the striker 319. A crankshaft 316 is movably installed inside the connector 318. A wheel 317 is installed at one end of the crankshaft 316.

[0064] The inner wall of outer compartment 311 is provided with a sliding groove;

[0065] The two ends of the crankshaft rod 316 pass through the second baffle plate 370 and the constant pressure assembly 340, respectively.

[0066] When solid waste is poured from the two feed hoppers 350 into the inner cavity of the two filter tanks 312, under the action of gravity, the waste liquid can be transferred along the discharge assembly 320 to the slag screening assembly 330 after being filtered by the filter screen 313 and the filter tank 312. Finally, the slag in the waste liquid can be filtered for the third time by the hopper 331, and the filter slag 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 components 200 will rise, and finally the grading filter material mechanism 300 will rise as a whole. At this time, the excess waste liquid can be effectively discharged outward along the drainage trough 140, and the solid material remaining on the filter screen 313 can be effectively stored.

[0067] When avoiding interference from natural factors, the solid material stored on the filter screen 313 can be dried in both directions. After the solid material is effectively dried, the motor can be started. When the chain 450 is actively driven, the two drive shaft sleeves 460 will push the extended screw 390 to retract into the waste liquid release mechanism 100. Finally, the scraper 380 can push the solid material on the top of the filter screen 313 laterally towards the pressure plate 360. During the lateral pushing process, the vibration wave released by the high-frequency impact of the outer chamber 311 can loosen the clump of solid material. The dustproof plate 335 covers the filter tank 312, which can prevent dust and odor from spreading during the solid material removal.

[0068] Example 2:

[0069] Combination Figures 5 to 10 As shown, in the above embodiment, the pressure regulating component 340 includes a first baffle plate 341, four legs 342 fixedly installed on the outer wall of the first baffle plate 341, and a compression spring 343 disposed outside the legs 342.

[0070] The slag screening assembly 330 includes two partitions 332 movably installed on the inner wall of the second baffle plate 370 and the inner wall of the first baffle plate 341, a hopper 331 installed between the two partitions 332, a clamping plate 333 installed on the inner side of one of the partitions 332, two first beams 334 installed inside the two partitions 332, and two dustproof plates 335 movably installed on the outside of the two first beams 334.

[0071] The dustproof plate 335 has a slide rail inside, and a second beam 336 is installed in the slide rail;

[0072] The two ends of the second beam 336 are respectively installed inside the top of the second baffle plate 370 and the first baffle plate 341.

[0073] Preferably, the bottom end of the pull rod 440 is installed inside the clamping plate 333. When the feeding assembly 320 is running, its internal hydraulic rod will drive the end plate 430 and the pull rod 440 to move up and down. The pulled partition 332 and the hopper 331 can be lifted upward. At this time, the filter residue stored inside the hopper 331 can be naturally dried after being lifted upward. The two dustproof plates 335 pushed upward will be vertically flipped to the top of the two filter tanks 312. Finally, the filter tank 312, the dustproof plate 335 and the outer chamber 311 can form a sealed cavity. When the scraper 380 is pushed horizontally, the dried sludge on the top of the filter screen 313 can be pushed horizontally towards the pressure plate 360 ​​in the sealed cavity, thereby effectively avoiding the problems of dust and odor during the removal of dried sludge.

[0074] Both the first baffle plate 341 and the second baffle plate 370 have discharge slots inside, and two symmetrically distributed feed bins 350 are installed in the two slots at the top of the first baffle plate 341.

[0075] The grooves of the two feed hoppers 350 are respectively connected to the inner cavities of the two filter tanks 312;

[0076] The inner wall of the pressure plate 360 ​​is provided with symmetrically distributed raised pads, and the raised pads are adapted to be snapped into the groove inside the first liquid baffle 341.

[0077] The support leg 342 extends through the outside of the pressure plate 360, and one end of the compression spring 343 is pressed against the outer end of the support leg 342, while the other end of the compression spring 343 is pressed against the outer wall of the pressure plate 360.

[0078] Preferably, the second baffle plate 370 and the first baffle plate 341 are installed at both ends of the two outer chambers 311, and the first baffle plate 341 and the second baffle plate 370 are fixed to both ends of the two outer chambers 311 by welding. As the scraper 380 pushes the sludge and applies pressure to the pressure plate 360, the pressure plate 360, which is elastically supported by four compression springs 343, can discharge the sludge in a uniform manner.

[0079] At the same time, after the pressure plate 360, which is pressed by four compression springs 343, comes into contact with the first baffle plate 341, the filter pool 312, the second baffle plate 370 and the first baffle plate 341, which form a pool-shaped structure, can actively screen the dumped solid waste.

[0080] Example 3:

[0081] Combination Figures 8 to 10As shown, in the above embodiment, the feeding assembly 320 includes a slide plate 321 movably installed in the inner wall groove of the hopper 331, a plurality of guide rods 322 movably installed in the inner wall plate of the slide plate 321, an inclined plate 323 installed on the outer ends of the plurality of guide rods 322, and a spring 324 disposed outside the guide rods 322.

[0082] One end of the spring 324 is connected to the inner wall of the ramp 323, and the other end of the spring 324 is connected to the plate on the inner wall of the slide 321.

[0083] Preferably, the bottom end of the inclined plate 323 is located directly above the hopper 331, and the arc-shaped end face of the bottom end of the inclined plate 323 is adapted to fit the port at the top of the hopper 331. After the hopper 331 performs the third filtration of the residue in the waste liquid, the hopper 331, after being lifted upward, will squeeze the two inclined plates 323 outward. Finally, the filter residue stored in the inner cavity of the hopper 331 can be naturally dried after being lifted upward.

[0084] The dirt that falls onto the inclined surface of the inclined plate 323 will be blocked by the outer wall of the hopper 331. After the hopper 331 is reset, the dirt on the inclined surfaces of the two inclined plates 323 will be effectively transferred into the hopper 331. When the amount of residue 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 dirt affecting the subsequent removal of solid waste materials.

[0085] Example 4:

[0086] Combination Figures 4 to 11 As shown, in the above embodiment, the drive mechanism 400 includes a transmission assembly 410 mounted on the outer wall of the second baffle plate 370, a hydraulic component 420 disposed within the transmission assembly 410, an end plate 430 mounted on the hydraulic rod within the hydraulic component 420, a pull rod 440 mounted at the other end of the end plate 430, two first brackets 470 mounted on the outer wall of the second baffle plate 370, and a second bracket 480 mounted within the first brackets 470.

[0087] The transmission assembly 410 consists of a chassis and a motor, and a gear is mounted on the shaft of the motor, with a chain 450 externally connected to the gear.

[0088] The two ends of the chain 450 are connected to two drive bushings 460, and the drive bushings 460 are connected to a drive belt 490.

[0089] The drive bushing 460 is composed of an I-shaped bushing, a gear disc, and a pulley. The I-shaped bushing has a threaded hole inside that is adapted to the extended lead screw 390.

[0090] Preferably, the transmission assembly 410 is fixedly mounted on the outer wall of the second baffle plate 370 by bolts, and two sets of clamps are installed on the inner wall of the chassis, while the hydraulic component 420 is fixed in the two sets of clamps;

[0091] Two first brackets 470 are fixedly installed on both sides of the outer wall of the second baffle 370 by welding, while two second brackets 480 are fixedly welded inside the first brackets 470, and the second brackets 480 are used to provide sufficiently stable limiting support for the lateral movement of the extended lead screw 390.

[0092] Two drive bushings 460 are movably installed inside the two first supports 470. When the motor is running, the bearing inside the motor will drive the gear transmission chain 450. Finally, the two drive bushings 460 will push the extended screw 390 to retract into the waste liquid release mechanism 100 during rotation. The scraper 380 installed at the inner end of the extended screw 390 can actively scrape off the dried sludge on the top of the filter screen 313. The rotating wheel 317 and crankshaft 316 driven by the transmission belt 490 will drive multiple adapters 318 and multiple impact pins 319 to extend at high frequency. Finally, the impact pins 319 will strike the column head 315. At this time, the outer chamber 311 and the filter tank 312 as a whole can loosen the clumped sludge, thereby realizing the rapid discharge of dried sludge.

[0093] The working principle and usage process of this invention: Hydraulic component 420 is pre-operated. When the hydraulic rod inside the hydraulic component 420 retracts, the end plate 430 and pull rod 440 installed at the top of the hydraulic rod will push the slag screening assembly 330, the combined hopper 331 and the two partitions 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 dustproof plates 335 pulled by the two partitions 332 will be pressed and flipped upward from the top of the two filter tanks 312 until the two dustproof plates 335 are distributed in a vertical state.

[0094] Next, the solid and liquid waste is transferred along the two feed hoppers 350 to the grooves of the pre-installed filter tanks 312 and filter screens 313. Since the top of the filter tank 312 is exposed, the solid and liquid materials under gravity can be quickly filtered by the filter screens 313. The liquid that passes through the filter screens 313 will drip down along the filter holes inside the filter tank 312, and the filtered liquid will be discharged along the inclined surface inside the outer hopper 311. Finally, the dripping waste liquid will flow down along the top surface of the discharge assembly 320 and finally enter from the top of the hopper 331. The ultrafiltration membrane installed at the bottom of the inner side of the hopper 331 can filter the waste liquid that enters later. As the waste liquid is continuously transferred to the inner cavity of the base 110, the two sets of buoyancy components 200 will be buoyed and thus drive the grading filter media mechanism 300 to rise as a whole until the baffle 220 rises from the inside of the drainage trough 140. At this time, the inner cavity of the base 110 can be released outward from the multiple drainage troughs 140 opened at the bottom of the two bases 130. The material transferred to the grading filter media mechanism 300 in a rated amount can be effectively separated into solid and liquid. The screened solid material can be quickly dried under the meandering airflow released from the inner cavity of the waste liquid release mechanism 100 and the blowing of natural airflow.

[0095] After the solid material dries, the hydraulic sub-rod inside the hydraulic component 420 is activated. Eventually, the hydraulic sub-rod will push the end plate 430 and the pull rod 440 to rise, and the screen assembly 330 being pulled will be lifted upward as a whole. After the two evenly distributed dustproof plates 335 are lifted upward, they will be vertically flipped under the pressure of the two second beam rods 336 until the two dustproof plates 335 cover the top of the two filter tanks 312.

[0096] Next, the motor inside the transmission assembly 410 is activated. As the gear at the outer end of the inner shaft of the motor rotates, the chain 450, which is actively driven, drives the two drive bushings 460 to rotate at the same speed. At this time, the two drive bushings 460 will assist the two extended lead screws 390. Finally, the scraper 380 installed at the inner end of the extended lead screw 390 will move laterally along the top surface of the two filter screens 313, thereby pushing the dried solid material on the top of the filter screens 313 laterally toward the inner side of the first baffle plate 341. As the solid material accumulates and is squeezed by the pressure plate 360, the solid material will flow outward from the groove inside the first baffle plate 341. Effective overflow occurs during the horizontal push of the scraper 380. The two transmission belts 490 driven by the two drive shaft sleeves 460 drive the two rotating wheels 317. Finally, the rotating crankshaft 316 drives multiple adapters 318 and multiple impact pins 319 to rise and fall at high frequency. At this time, the impact pins 319 will reciprocate up and down along the inside of the support plate 314, and the top of the impact pins 319 will apply high-frequency impact to the column head 315. At this time, the outer chamber 311 and the filter tank 312 can radiate the vibration force into the settled solid material. The solid material that has been pushed and resonated can be squeezed out from the gap between the pressure plate 360 ​​and the first baffle plate 341.

[0097] The filter residue stored in the rising hopper 331 can be quickly and naturally dried, and the solid material removal process can avoid the problem of solid material overflowing or producing abnormal odors due to vibration.

[0098] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
