Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a waste residue recovery device for heavy metal wastewater treatment. Background Technology

[0002] During the treatment of heavy metal wastewater, a displacement reaction occurs, resulting in small particles that are insoluble in water. In order to reuse the resources, these small particles need to be recycled.

[0003] Existing technology involves first injecting a mixture of liquid and solid into a filter cylinder through a conduit, then sealing the filter cylinder and rotating it to separate the water. After separation, the filtered particles are poured out. When small batches of material need to be filtered multiple times, it is necessary to manually transfer the material in different states multiple times, which is time-consuming and inefficient. During the rotation of the filter cylinder, the material also adheres to the inside of the filter cylinder, requiring manual cleaning, which is troublesome. Therefore, we propose a waste residue recovery device for heavy metal wastewater treatment. Summary of the Invention

[0011] This invention provides a waste residue recovery device for heavy metal wastewater treatment. It has the following beneficial effects:

[0012] (1) The waste residue recovery device for heavy metal wastewater treatment, through the cooperation between the transmission structure, the guiding structure and the pretreatment structure, allows the material to fall into the interior of the pretreatment structure under the drive of the transmission structure and accumulate. Then, the material in the pretreatment structure is processed by the transmission structure. After the processing is completed, the material falls into the interior of the filter structure through the cooperation between the transmission structure and the filter structure for filtration. Then, the material is moved from the interior of the filter structure to the position of the discharge structure by the movement of the transmission structure. Thus, the material can be quickly filtered, making the whole process coherent and improving work efficiency.

[0013] (2) The waste residue recovery device for heavy metal wastewater treatment forms a chamber through the inner side wall of the mounting tank, the upper side wall of the first guide ring, the lower side wall of the second guide ring, the upper side wall of the first mounting ring, and the upper side wall of the second block. By rotating the second block, the clump of particles inside the chamber collide with the first and second stirring rods that rotate with the second block, thereby breaking up the clump of particles and improving the subsequent water filtration effect.

[0014] (3) The waste residue recovery device for heavy metal wastewater treatment forms a chamber between the inner wall of the installation barrel, the outer wall of the first movable cylinder, and the upper wall of the second guide ring for storing materials. During use, the materials to be processed can continuously enter the interior of the chamber through the second movable cylinder to ensure that there are enough materials when water filtration is required, thereby achieving the effect of quickly filling materials and improving the efficiency of use.

[0015] (4) The waste residue recovery device for heavy metal wastewater treatment allows the movable sleeve to move up and down through the connecting ring and to rotate through the second movable cylinder. When moving vertically, the rotation of the movable sleeve causes the scraper to scrape the side wall of the filter bucket. During the scraping process, when the scraper moves to the groove position, the second spring drives the scraper to move to the groove position to change the trajectory of the movement. This causes vibration during the movement, which allows the particles stuck in the gaps of the filter screen to be shaken off and improves the working efficiency.

[0016] (5) The waste residue recovery device for heavy metal wastewater treatment uses a scraper to push and move the material falling above the rotating disk by the side of the scraper until it is pushed into the inside of the feeding trough, thereby increasing the material flow rate.

[0017] (6) When the material to be filtered does not have agglomeration, the third block is moved to the bottom of the discharge trough. The material above the second guide ring falls directly into the filter tank through the discharge trough and the first mounting ring. After the feeding is completed, when the first block is upward inside the guide cylinder, the first block brings the material inside the guide cylinder into the filter tank to perform the water filtration operation and improve the applicability of the device.

The levers 4412 drive the first movable cylinder 353 to rotate.

[0041] Working principle of the invention:

[0042] In use, a mixture of solid particles and liquid enters through the feed hole 4413 and falls onto the second guide ring 352. At this time, a chamber is formed between the inner wall of the mounting barrel 331, the outer wall of the first movable cylinder 353, and the upper side of the second guide ring 352 to hold the material. The material then flows downwards along the inside of the discharge chute 441, falling above the first mounting ring 432 and the second block 431 until it reaches the position of the discharge chute 441. At this point, a chamber is formed between the inner side of the mounting barrel 331, the upper side of the first guide ring 351, the lower side of the second guide ring 352, the upper side of the first mounting ring 432, and the upper side of the second block 431, driving the second block 431... 31 moves downward, the second blocking block 431 drives the snap ring 434 to move downward inside the snap cavity 433, so that the snap ring 434 and the snap cavity 433 are not separated. When the second blocking block 431 moves downward, it drives the first movable cylinder 353 to move downward. The first movable cylinder 353 drives the third blocking block 447 to move downward. The lower end of the third blocking block 447 enters the interior of the discharge trough 441 to block the discharge trough 441. The second blocking block 431 is started to rotate. The second blocking block 431 drives the first stirring rod 435 and the second stirring rod 436 to rotate. During the rotation, the first stirring rod 435 and the second stirring rod 436 break up the small clumps of particles.

[0043] The second blocking block 431 continues to move downwards, causing the locking ring 434 to separate from the locking cavity 433. At this time, the third blocking block 447 is still inside the discharge trough 441, sealing the discharge trough 441. This allows the material to fall into the filter bucket 334 through the gap between the first mounting ring 432 and the second blocking block 431. The second blocking block 431 then moves upwards, causing the locking ring 434 to move to the inside of the locking cavity 433 for sealing. At this time, the third blocking block 447 moves to the inside of the discharge trough 441, allowing the material above the material chamber to fall down again and accumulate inside the filter bucket 334. At this time, the first blocking block 421 blocks the lower end of the filter bucket 334.

[0044] Start the first rotary motor 211, which drives the rotating column 212 to rotate. The rotating column 212 drives the rotating disk 213 to rotate. The rotating disk 213 drives the first telescopic motor 214 and the first telescopic rod 215, which are circumferentially distributed above the rotating disk 213, to rotate. The first telescopic rod 215 drives the guide cylinder 311 to rotate. The guide cylinder 311 drives the water filter bucket 334 to rotate.

[0045] The second rotary motor 413 is started, which drives the rotary shaft 414 to rotate. The rotary shaft 414 drives the first rotary gear 415 to rotate, which in turn drives the spline sleeve 419 to rotate on the bearing seat 418. The spline sleeve 419 drives the spline shaft 4110 to rotate, which in turn drives the first connecting post 4111 to rotate. The second movable cylinder 4113 is located in the movable groove 4112 at the upper end of the first connecting post 4111. When the column 4111 rotates, it drives the second movable cylinder 4113 to rotate along with the first connecting column 4111 through the constraint groove 4116 and constraint block 4117. The second movable cylinder 4113 drives the second blocking block 431 to rotate, the second blocking block 431 drives the connecting limiting cylinder 449 to rotate, the connecting limiting cylinder 449 drives the connecting rod 4411 to rotate, the connecting rod 4411 drives the lever 4412 to rotate, and the lever 4412 drives the first movable cylinder 353 to rotate.

[0046] When the filter bucket 334 rotates, the material accumulated inside the filter bucket 334 is dehydrated by rotation. After the material inside the filter bucket 334 is dehydrated, the second telescopic motor 416 is driven. The second telescopic motor 416 causes the second telescopic rod 417 to extend upward. The second telescopic rod 417 causes the spline shaft 4110 to move upward inside the spline sleeve 419. The spline shaft 4110 drives the first connecting column 4111 to move upward. The first connecting column 4111 drives the first block 421 to move upward. The first block 421 moves upward to the inside of the filter bucket 334, so that the material inside the filter bucket 334 falls into the inside of the guide cylinder 311 through the lower opening of the filter bucket 334. The material then falls into the inside of the feeding cylinder 321 along the guide cylinder 311. The material then falls into the inside of the collecting trough 325 through the feeding trough 322. The material is then discharged through the discharge pipe 326.

[0047] When the material inside the filter bucket 334 is discharged into the filter bucket 334, the first block 421 drives the support column 422 to move upward, the support column 422 drives the connecting ring 423 to move upward, the connecting ring 423 drives the movable sleeve 424 to move upward, and the first block 421 drives the second movable cylinder 4113 to rotate when rotating, and the second movable cylinder 4113 drives the extension rod 425 to rotate. At this time, the movable sleeve 424 moves upward while rotating, and the movable sleeve 424 drives the extension rod 425 to move. The extension rod 425 pushes the scraper 429 to move along the inner side of the filter bucket 334 through the second spring 427. During the movement, the material adhering to the wall of the filter bucket 334 is scraped. When the scraper 429 moves to the position of the groove 335, the second spring 427 will squeeze the squeezing column 428 and the scraper 429 to generate vibration on the wall of the filter bucket 334. The vibration will also cause the material adhering to the wall of the filter bucket 334 to fall off.

[0048] When the spline shaft 4110 rotates, it drives the scraper 324 to rotate. When the scraper 324 rotates, it pushes the material falling above the rotating disk 213 into the inside of the feed trough 322, so that the material flows quickly.

[0049] When the material to be filtered is free of lumps, the second block 431 moves downward. After the second block 431 causes the locking ring 434 to separate from the locking cavity 433, the second block 431 continues to move downward. The second block 431 causes the connecting limiting cylinder 449 to move downward, which in turn causes the connecting rod 4411 to move downward. The connecting rod 4411 causes the lever 4412 to move downward, which in turn causes the first movable cylinder 353 to move downward. The first movable cylinder 353 causes the constraint ring 444 to move downward, which in turn causes the second mounting ring 442 to move downward. The second mounting ring 442 causes the third block 447 to move downward, and the third block 447 moves to the discharge chute 4. When the material is below 41, it falls downward through the discharge chute 441, so that the material above the second guide ring 352 can fall directly into the interior of the filter bucket 334. When it is necessary to seal the interior of the filter bucket 334, the first connecting column 4111 moves upward. The first connecting column 4111 drives the first blocking block 421 upward. The first blocking block 421 drives the second movable cylinder 4113 upward. The second movable cylinder 4113 drives the second blocking block 431 upward. The second blocking block 431 drives the locking ring 434 to seal the locking cavity 433. When the first blocking block 421 moves upward inside the guide cylinder 311, the first blocking block 421 brings the material inside the guide cylinder 311 into the interior of the filter bucket 334 for filtration.
