Abstract

The present invention relates to the field of wastewater recycling and treatment technology, and specifically to a concentrating device for recycling heavy metal wastewater, comprising a side plate, a fixed plate, a mounting plate, a processing mechanism, and an auxiliary mechanism. In the present invention, heavy metal wastewater is poured into the device from a water inlet, and then a filter screen on a movable plate first performs a primary filtration on the heavy metal wastewater, filtering out larger-sized particles and other impurities therein to prevent them from damaging subsequent filter components. Thereafter, the activated carbon layer, filter cotton layer, and reverse osmosis membrane layer in the filter component perform a secondary filtration on the wastewater. The two filtration operations ensure the filtration treatment effect of the heavy metal wastewater, and at the same time, the water filtered out by the reverse osmosis membrane layer flows out from a second water outlet, while the wastewater with residual heavy metals flows out from a first water outlet, facilitating subsequent concentration operations and improving overall work efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of wastewater recycling and treatment, in particular to a concentrating device for recycling heavy metal wastewater. Background Art

[0002] Heavy metal wastewater recycling refers to the treatment of wastewater containing heavy metals to remove or recover heavy metal components in the wastewater, such as lead, mercury, cadmium, chromium, copper, zinc and other heavy metal components, so as to reduce environmental pollution and waste of resources.

[0003] After heavy metal recovery, the wastewater is first pretreated, and then filtered and concentrated. The purpose of the filtration operation is to separate the water in the wastewater and discharge it. The remaining wastewater containing heavy metal components is then concentrated to complete the treatment of heavy metal wastewater. Currently, when filtering heavy metal wastewater, water is mainly separated from the wastewater through a reverse osmosis membrane.

[0004] The following problems exist in the current treatment process: 1. In the process of filtering heavy metal wastewater, the wastewater is mainly sent to the reverse osmosis membrane to separate the water and the wastewater containing heavy metals to achieve the filtering effect. This method has a single filtering effect and a poor effect. At the same time, its filtration efficiency is low, and the wastewater contains other solid substances that can easily damage the reverse osmosis membrane, resulting in a shorter overall service life.

[0005] 2. At present, when filtering, the reverse osmosis membrane is mainly installed in a closed cylindrical structure, and then the heavy metal wastewater is poured into it for filtration. After a long period of filtration operation, the inside of the membrane is prone to blockage or damage, so the filtration effect of the heavy metal wastewater becomes worse and the filtration efficiency becomes low.

DETAILED DESCRIPTION

[0033] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a heavy metal wastewater recovery and concentration device comprises:

[0035] The side panels 1 are arranged symmetrically front to back, and an outer cylinder 2 is fixedly provided between the two side panels 1 through a plurality of connecting blocks arranged equidistantly from left to right, and a circular fixing plate 3 is fixedly provided on the right end face of the outer cylinder 2.

[0036] A mounting plate 4 is provided on the left end surface of the outer cylinder 2 .

[0037] Treatment mechanism 5; a treatment mechanism 5 for treating heavy metal wastewater is provided in the outer cylinder 2, and an auxiliary mechanism 6 is provided on the outer cylinder 2.

[0038] like Figure 2 、 Figure 4 and Figure 7As shown, the processing mechanism 5 includes a rotating kit 50, and the rotating kit 50 is rotatably provided on the mounting plate 4. The rotating kit 50 includes two left-right symmetrical rotating rings 500 and a plurality of circumferentially evenly distributed connecting rods 501 between the two rotating rings 500 and used to connect the two. The left rotating ring 500 is rotatably connected to the mounting plate 4, and the right rotating ring 500 is installed with the fixed plate 3 in a sealing sleeve. The left rotating ring 500 is a water inlet 51, and the right rotating ring 500 is a water outlet 510. The outer cylinder 2 is fixedly provided with a pipe connected to the inner cavity of the outer cylinder 2 below the right circumferential surface, and the pipe is a water outlet 2 511. A valve (not shown in the figure) is fixedly provided at the right end of the right rotating ring 500. A fixed ring plate 52 is fixedly provided on the inner ring surface of the right rotating ring 500. A receiving cylinder through which water can flow is fixedly provided on the left end surface of the fixed ring plate 52. A filter assembly 53 for filtering wastewater is provided in the receiving cylinder. The filter assembly 53 includes an activated carbon layer 530, a filter cotton layer 531 and a reverse osmosis membrane layer 532.

[0039] During operation, heavy metal wastewater enters the rotating kit 50 through the water inlet 51, and then the filter component 53 is set to filter the heavy metal wastewater. The heavy metal wastewater passes through the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 in turn and is filtered. The treated water then passes through the filter component 53 and flows into the area outside the filter component 53 in the outer cylinder 2, and continuously flows out through the water outlet 2 511. The staff opens the valve, so some sewage that cannot be filtered and concentrated flows out through the water outlet 2 511, thereby carrying out continuous treatment operations for the recovery of heavy metal wastewater.

[0040] The multiple connecting rods 501 in the rotating kit 50 protect the filter assembly 53, making it easier for the filter assembly 53 to treat heavy metal wastewater.

[0041] like Figure 4 、 Figure 5 and Figure 6 As shown, the filter assembly 53 also includes a support plate 533. The left end surface of the fixed ring plate 52 is provided with four circumferentially evenly distributed and arc-shaped support plates 533. The left end surfaces of the four support plates 533 are commonly fixedly provided with a movable plate 534. A filter screen 535 for preliminary filtration of wastewater is provided at the middle position of the movable plate 534. The opposite surfaces of the movable plate 534 and the fixed ring plate 52 are fixedly provided with a plurality of circumferentially evenly distributed positioning components 536. The positioning components 536 on the movable plate 534 are explained as follows. The positioning components 536 include a partition 5360. The right end surface of the movable plate 534 is fixedly provided with two partitions 5360 for separating the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532, and the three are arranged from the inside to the outside in the order of the filter cotton layer 531, the activated carbon layer 530 and the reverse osmosis membrane layer 532 (see Figure 7 ), two abutting plates 5361 are fixedly provided on the two corresponding partitions 5360, and a fixing group 54 is commonly provided between the movable plate 534 and the left rotating ring 500.

[0042] like Figure 5 As shown, the fixed group 54 includes a sliding groove 540, and the inner ring surface of the rotating ring 500 on the left is provided with a plurality of sliding grooves 540 evenly distributed in the circumferential direction. The circumferential surface of the movable plate 534 is fixedly provided with sliding blocks 541 corresponding to the sliding grooves 540 one by one. The sliding block 541 directly below is used for illustration. The front and rear end surfaces of the sliding block 541 are fixedly provided with spring rods 542, and the end surface of the spring rod 542 away from the sliding block 541 is fixedly provided with a semicircular locking ball 543. The opposite surface of the sliding groove 540 and the sliding block 541 is provided with a locking groove 544 with a semicircular shape that cooperates with the locking ball 543.

[0043] After the mounting plate 4 and the rotating ring 500 are installed, the filter assembly 53 is manually placed into the rotating kit 50 through the left rotating ring 500, that is, the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 are first respectively inserted between the partitions 5360 on the right fixed ring plate 52. At this time, there is a certain distance between the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532, which is convenient for the subsequent filtration treatment of heavy metal wastewater. Finally, the movable plate 534 on the left is placed into the rotating ring 500 on the left, and the left ends of the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 are also inserted into the corresponding positions on the movable plate 534. At this time, the right end face of the movable plate 534 is in contact with the left end face of the accommodating cylinder, and the sliding block 541 is located in the corresponding sliding groove 540. The movable plate 534 is continuously pushed to move right, so the card ball 543 on the sliding block 541 is locked into the corresponding card slot 544 under the elastic force of the corresponding spring rod 542, so the position of the movable plate 534 is limited and fixed, and the position of the filter assembly 53 is fixed, which is convenient for subsequent filtering operations. At the same time, when the heavy metal wastewater enters the filter assembly 53, the filter mesh 535 on the movable plate 534 is firstly filtered to filter the wastewater, so that larger waste in the wastewater is screened out, avoiding the problem of larger waste entering the filter assembly 53 and causing the filter assembly 53 to be blocked. After that, the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 in the filter assembly 53 perform secondary filtration on the wastewater. The filtering treatment effect of the heavy metal wastewater is guaranteed through two filtering operations.

[0044] And by using the installation method in which the filter component 53 is installed separately and is clamped by the sliding block 541, when the filtering effect of the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 in the filter component 53 becomes poor after long-term use, the three can be replaced by directly pulling out the movable plate 534 on the left, thereby improving the convenience of the device during use and maintenance.

[0045] like Figure 6 As shown, a self-cleaning group 55 is commonly provided between the four support plates 533, and the self-cleaning group 55 includes a movable groove 550. The inner arc surface of the support plate 533 is provided with a movable groove 550, and a movable circular plate 551 in a circular shape is fixedly provided in the four movable grooves 550 through a movable block. A plurality of scraping plates 552 located between two adjacent support plates 533 are fixedly provided on the outer ring surface of the movable circular plate 551, and a driving group 56 for driving the scraping plate 552 to scrape is provided on the movable circular plate 551.

[0046] like Figure 7 and Figure 8 As shown, the driving group 1 56 includes a baffle 560, and the inner ring surface of the movable circular plate 551 is fixedly provided with the baffle 560, and the right end surface of the baffle 560 is provided with a baffle groove 561. The inner ring surface of the movable circular plate 551 is hinged with two baffles 562 that are symmetrical front and back and have a semicircular shape through a square block, and the baffle 562 is fixedly provided with a matching block 563 that cooperates with the baffle groove 561 on the end surface facing the baffle 560.

[0047] When the filter cotton layer 531 that is in direct contact with heavy metal wastewater has its inner circumferential surface blocked with impurities in the wastewater after long-term use, thereby affecting the wastewater from passing through its surface into the filter assembly 53 for filtration treatment, which is prone to clogging problems, the wastewater is first stopped from being transported into the device, and then the external pipe (not shown in the figure) supplies water to the filter assembly 53 through the right rotating ring 500. Since the retaining groove 561 cooperates with the front and rear matching blocks 563, the two baffles 562 are then opened to the right. Therefore, when water is supplied to the right rotating ring 500, under the impact of the water flow, the two baffles 562 and the movable circular plate 551 remain in a closed state. Therefore, the movable circular plate 551 drives the scraper plate 552 on it to move left. Therefore, the scraper plate 552 cleans the inner arc surface of the accommodating cylinder during the left movement, avoiding the problem of clogging after long-term use and improving the service life of the filter assembly 53.

[0048] When the movable circular plate 551 drives the scraper plate 552 to move left to a position close to the left rotating ring 500 and performs self-cleaning operations, the heavy metal wastewater is again transported to the filter assembly 53 through the water inlet 51. As the water flow impacts the baffle 562, the two baffles 562 open to facilitate the circulation of wastewater in the filter assembly 53. At the same time, as the water flow impacts the movable circular plate 551 for a long time, the scraper plate 552 driven by the movable circular plate 551 moves to the right after a long period of wastewater supply, completing the reset action, so as to facilitate the subsequent cleaning of the filter assembly 53 again.

[0049] like Figure 2 and Figure 3 As shown, the auxiliary mechanism 6 includes a fixing group 2 60 located on the circumferential surface of the outer cylinder 2 and a driving group 2 61 located on the mounting plate 4, the fixing group 2 60 includes an arc groove 600, and the circumferential surface of the outer cylinder 2 close to the mounting plate 4 is provided with a plurality of circumferentially evenly distributed arc grooves 600, and the inner wall of the arc groove 600 is provided with a limiting groove 601 facing the axis of the outer cylinder 2 and in a circular shape, and a placement plate 602 is fixedly provided on the right end face of the mounting plate 4, and a positioning rod 603 is movably installed on the placement plate 602, and the positioning rod 603 is fixedly provided with a limiting block 604 facing the end face of the outer cylinder 2, and the limiting block 604 is fixedly provided with a limiting column 605 that cooperates with the limiting groove 601 towards the end face of the outer cylinder 2, and a spring mounted on the positioning rod 603 is fixedly provided between the positioning rod 603 and the placement plate 602.

[0050] like Figure 4 As shown, the driving group 2 61 includes a rotating shaft 610, and the left end face of the mounting plate 4 is rotatably provided with a rotating shaft 610, the rotating shaft 610 is connected to an external motor 1, and a driving gear 611 is fixedly sleeved on the rotating shaft 610, and the outer ring surface of the left rotating ring 500 is fixedly sleeved with a toothed ring 612 that meshes with the driving gear 611.

[0051] Before filtering the wastewater, the mounting plate 4 is placed on the left side of the outer cylinder 2, and the limit block 604 is located in the corresponding arc groove 600. Then the mounting plate 4 is rotated, and the mounting plate 4 drives the placement plate 602 and the limit block 604 thereon to rotate synchronously. When the placement plate 602 drives the limit block 604 to move to a position aligned with the corresponding limit groove 601, the limit column 605 is clamped into the corresponding limit groove 601 under the elastic force of the set spring, so the two cooperate with each other to limit and fix the limit block 604 and the placement plate 602. The positions of the three placement plates 602 are fixed, so that the mounting plate 4 is limited and fixed to the left end surface of the outer cylinder 2. This installation method of the mounting plate 4 facilitates the subsequent cleaning of the inner cavity of the outer cylinder 2, avoiding the problem that the inner cavity of the outer cylinder 2 is contaminated with impurities after a long period of filtration, thereby improving the service life of the device.

[0052] When the mounting plate 4 is installed and subsequent filtering operations are performed, the external motor starts to drive the rotating shaft 610 to rotate synchronously, and the rotating shaft 610 drives the driving gear 611 to rotate synchronously in the forward direction. The engagement between the driving gear 611 and the toothed ring 612 enables the toothed ring 612 to drive the left rotating ring 500 to rotate synchronously, so the left rotating ring 500 drives the entire rotating kit 50 to rotate synchronously. Because the filter assembly 53 is limited on the two rotating rings 500 by the sliding block 541, the filter assembly 53 rotates synchronously. Therefore, after the metal wastewater enters the filter assembly 53, the centrifugal force generated by its rotation causes the heavy metal wastewater to be quickly filtered, that is, the filtration efficiency during the overall operation is improved while the filtration effect of the filter assembly 53 on the heavy metal wastewater is improved.

[0053] During the specific work, first, the mounting plate 4 is fixed to the left end face of the outer cylinder 2 through the operation of the fixing group 2 60, and then the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 are respectively inserted between the partitions 5360 on the right fixed ring plate 52, and then the three are fixed by the fixing group 1 54. Then the heavy metal wastewater enters the rotating kit 50 through the water inlet 51, and the filter component 53 set thereafter filters the heavy metal wastewater. The heavy metal wastewater passes through the activated carbon layer 530, the filter cotton layer 531 and the reverse osmosis membrane layer 532 in turn and is filtered. After that, the treated water passes through the filter component 53 and flows into the area outside the filter component 53 in the outer cylinder 2, and continuously flows out through the water outlet 2 511. The staff opens the valve, so some sewage that cannot be filtered and concentrated flows out through the water outlet 2 511, thereby carrying out the continuous treatment operation of recovering the heavy metal wastewater.

[0054] During the filtering process, the external motor 1 drives the rotating shaft 610 to rotate synchronously, and the operation of the driving group 2 61 causes the left rotating ring 500 to drive the entire rotating kit 50 to rotate synchronously. The filter assembly 53 is limited on the two rotating rings 500 by the sliding block 541, so that the filter assembly 53 rotates synchronously. Therefore, after the metal wastewater enters the filter assembly 53, the centrifugal force generated by its rotation causes the heavy metal wastewater to be quickly filtered.
