Description

Technical Field

[0001] This invention relates to the field of waste residue treatment and reuse technology, specifically to a waste residue treatment and reuse device for coal-water treatment. Background Technology

[0002] The core working principle of the coal water waste residue treatment and reuse technology is to achieve coal water purification and waste residue resource utilization through a closed-loop process of pretreatment, flocculation, sedimentation, solid-liquid separation, waste residue purification and clean water reuse. Each link works together to remove impurities and recover resources. Flocculants are precisely added to the regulated coal water. Through adsorption and bridging, the flocculants cause fine coal dust and suspended solids to aggregate into large flocs. The coal water containing flocs enters the sedimentation tank. The heavy flocs settle to the bottom of the tank, while a small amount of light scum (wood chips, loose flocs) floats on the surface.

[0003] In traditional coal-water waste treatment and reuse technologies, flocculants are mostly powders or liquids. When directly added to static coal-water, they tend to accumulate at the addition point, making it difficult for them to spread throughout the water body. This results in most suspended particles not coming into contact with the flocculant. Furthermore, the water flow during agitation causes existing scum to spread. Since scum is lightweight and easily piled up, if it is not removed in time, it may coat the flocculant, hindering contact between the flocculant and unreacted fine particles, leading to flocculant waste. After adding more flocculant, some residual suspended particles will form new loose flocs, which will rise to the surface more quickly when agitated. These new scum will accumulate on the water surface, resulting in an excessively thick scum layer during subsequent settling, which affects the treatment and reuse of the waste.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing waste residue treatment and reuse devices for coal-water treatment. Summary of the Invention

[0005] The present invention addresses the problem that existing technical solutions are too simplistic by providing a solution that is significantly different from existing technologies. Specifically, the purpose of the present invention is to provide a waste residue treatment and reuse device for coal-water treatment, in order to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste residue treatment and reuse device for coal-water treatment, comprising a main body, a movable frame slidably connected to the main body via a threaded rod, a lifting assembly at the bottom of the movable frame, a connecting seat fixed at the bottom of the lifting assembly, and the height of the connecting seat inside the main body being adjusted by the lifting assembly, a retrieval component fixed on one side of the connecting seat, the retrieval component having filter holes, a base fixed at the top of the retrieval component, a leveling assembly symmetrically arranged at the bottom of the base, a scraper at the bottom of the leveling assembly, and the scraper being driven to reciprocate by the leveling assembly to level the floating slag piled inside the retrieval component, a feeding cylinder at the top of the connecting seat, a fixed seat fixed at the bottom of the connecting seat, a stirring assembly inside the fixed seat, a stirring rod symmetrically fixed on one side of the stirring assembly, and the stirring assembly driving the stirring rod to rotate to fully mix the coal-water and flocculant.

[0007] Preferably, the lifting assembly includes a bidirectional lead screw that is connected through the movable frame. One end of the bidirectional lead screw is fixedly connected to the output end of the motor. The bidirectional lead screw is symmetrically connected to a slider via threads. Rotating plates are rotatably connected to both sides of the slider via connecting rods. A connecting plate is rotatably connected to the rotating plate via connecting rods. A lifting plate is fixed at the bottom end of the connecting plate.

[0008] Preferably, the lifting plate is fixedly connected to the connecting seat, and the lifting plate is slidably connected to the movable frame.

[0009] Preferably, the scraping assembly includes a rotating shaft disposed at the top of the base, the top of the rotating shaft being fixedly connected to the output end of the motor, a connecting plate being fixedly fixed at the bottom of the rotating shaft, a connecting rod being symmetrically connected to the top of the connecting plate via a connecting rod, a movable seat being rotatably connected to one side of the connecting rod via a connecting rod, a fixed plate being fixedly fixed at the bottom of the movable seat, an elastic telescopic rod being fixedly fixed at the bottom of the fixed plate, and the bottom of the elastic telescopic rod being fixedly connected to the scraper.

[0010] Preferably, a guide block is fixed on one side of the scraper, and a slide rail is symmetrically fixed on one side of the bottom side plate of the base. Limiting plates are provided on both sides of the slide rail, and limiting blocks are symmetrically staggered between the two limiting plates. The contact surfaces of the guide block and the limiting block are both inclined surfaces.

[0011] Preferably, the base has a cavity that mates with the movable seat, the connecting plate rotates with the top of the base, and the fixing plate slides at the bottom of the base.

[0012] Preferably, the stirring assembly includes a connecting shaft rotatably connected to a rotating shaft via a belt. Two swaying plates are fixed to the outer wall of the connecting shaft. A connecting column is rotatably connected between the two swaying plates via a connecting rod. A sliding rod is slidably connected to the connecting column. A rotating component is fixed to one end of the sliding rod, and a turntable is fixed to one end of the rotating component. A stirring rod is symmetrically fixed to one end of the turntable.

[0013] Preferably, the connecting shaft is through-connected to the fixed base, and the rotating component is through-connected to the fixed base.

[0014] Preferably, a groove is provided on one side of the connecting column to cooperate with the sliding rod, and the sliding rod slides in the groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, through the design of a movable seat, elastic telescopic rod, guide block, limiting block, and scraper, can simultaneously improve the scraping efficiency when water quality deteriorates and suspended solids increase, leading to an increase in scum. The forward rotation of the motor drives the rotating shaft, connecting plate, and movable seat in tandem. The elastic telescopic rod pushes the scraper to move, and the guide block slides along the bottom of the slide rail to complete the scraping, ensuring uniform scum thickness and preventing excessive local accumulation or omissions. This ensures that each scraper can effectively carry scum during retrieval. When the motor reverses, the guide block slides along the top of the slide rail, and the scraper does not contact the scum on its return stroke. This prevents uneven scum thickness that could lead to missed retrieval, and the return stroke avoids secondary diffusion of scum, preventing damage to the existing scum layer on the water surface. It also reduces the re-suspension of fine particles after scum breakage, which could affect the quality of the effluent. Furthermore, it reduces repeated friction between the scraper and hard impurities in the scum, minimizing equipment wear and extending the scraper's service life.

[0017] 2. This invention, through the design of a swaying plate, connecting column, sliding rod, and stirring rod, causes the connecting column to reciprocate horizontally when the swaying plate swings. Since the connecting column has a groove that slides with the sliding rod, the sliding rod slides within the groove, causing the rotating component and turntable fixed to the sliding rod to rotate. This, in turn, drives the swaying plate to swing and the stirring rod to rotate. When water quality deteriorates, the motor speed is increased to enhance stirring and ensure thorough mixing of the flocculant and coal-water mixture. When operating conditions are stable, a low to medium speed is maintained to balance effect and energy consumption, avoiding excessively high local concentrations of the agent (resulting in loose flocs) or excessively low concentrations (preventing floc formation), ensuring uniform flocculation reaction throughout the water body and guaranteeing sedimentation effect.

[0018] 3. This invention uses a motor to drive a bidirectional lead screw to rotate, and through the linkage of a slider, rotating plate, and lifting plate, drives the feeding cylinder and the retrieval component to adjust their height synchronously. The liquid level in the sedimentation tank fluctuates with the coal-water flow rate and processing volume, and the thickness of the scum layer varies with the working conditions. By adjusting the height of the feeding cylinder and the retrieval component, the feeding point always falls into the effective mixing zone, avoiding splashing of chemicals or impacting the scum. The retrieval scraper adheres to the bottom of the scum layer to ensure that the scum is completely scraped off. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 9This invention provides a technical solution: a waste residue treatment and reuse device for coal-water treatment, comprising a main body 1, a movable frame 2 slidably connected to the main body 1 via a threaded rod, a lifting component at the bottom of the movable frame 2, a connecting seat 4 fixed at the bottom of the lifting component, and the height of the connecting seat 4 inside the main body 1 adjusted by the lifting component, a scooping component 5 fixed on one side of the connecting seat 4, the scooping component 5 having filter holes, a base 6 fixed at the top of the scooping component 5, a leveling component symmetrically arranged at the bottom of the base 6, a scraper 8 at the bottom of the leveling component, and the scraper 8 being driven to reciprocate by the leveling component to level the floating slag piled inside the scooping component 5, a feeding cylinder 9 at the top of the connecting seat 4, a fixed seat 10 fixed at the bottom of the connecting seat 4, a stirring component inside the fixed seat 10, a stirring rod 12 symmetrically fixed on one side of the stirring component, and the stirring component driving the stirring rod 12 to rotate to fully mix the coal-water and flocculant.

[0031] In practice, the main body 1 drives the movable frame 2 to slide through the threaded rod. The lifting component at the bottom of the movable frame 2 drives the connecting seat 4 to adjust its height, thereby driving the retrieval part 5 on one side of the connecting seat 4 and the feeding cylinder 9 at the top to adapt to the liquid level and the thickness of the scum layer. After the flocculant is added to the feeding cylinder 9, the stirring component in the fixed seat 10 at the bottom of the connecting seat 4 drives the stirring rod 12 to rotate, so that the flocculant and coal water are fully mixed. At the same time, the scraping component at the bottom of the base 6 at the top of the retrieval part 5 drives the scraper 8 to move back and forth, scraping the scum piled up in the retrieval part 5 to level it, and finally achieving coal water purification and waste residue recycling.

[0032] Please see Figure 2 and Figure 3 As a further embodiment of the present invention, the lifting assembly includes a bidirectional lead screw 301 that is connected through the movable frame 2. One end of the bidirectional lead screw 301 is fixedly connected to the output end of the motor. The bidirectional lead screw 301 is symmetrically connected to a slider 302 by a thread. The slider 302 is rotatably connected to two sides by a connecting rod. The rotating plate 303 is rotatably connected to a connecting plate 304 by a connecting rod. The bottom end of the connecting plate 304 is fixed with a lifting plate 305.

[0033] In practice, the motor drives the bidirectional lead screw 301 to rotate. The bidirectional lead screw 301 drives the symmetrically connected slider 302 to move bidirectionally through the thread. The rotating plates 303 on both sides of the slider 302 rotate synchronously with the slider 302. Then, the connecting plate 304 connected by rotation drives the lifting plate 305 fixed at the bottom to slide up and down, so as to realize the height adjustment of the connecting seat 4 and related components.

[0034] Please see Figure 2 and Figure 3 As a further embodiment of the present invention, the lifting plate 305 is fixedly connected to the connecting seat 4, and the lifting plate 305 is slidably connected to the movable frame 2.

[0035] In practice, the motor drives the bidirectional lead screw 301 to move the slider 302 in both directions. Through the linkage of the rotating plate 303 and the connecting plate 304, the lifting plate 305 slides in the moving frame 2. The lifting plate 305 is fixedly connected to the connecting seat 4. Then, the up and down sliding of the lifting plate 305 can accurately drive the connecting seat 4 and the connected retrieval part 5 and feeding cylinder 9 to adjust their height synchronously to adapt to different working conditions.

[0036] Please see Figure 4 As a further embodiment of the present invention, the scraping assembly includes a rotating shaft 701 disposed at the top of the base 6. The top of the rotating shaft 701 is fixedly connected to the output end of the motor. A connecting plate 702 is fixed at the bottom of the rotating shaft 701. A connecting rod 703 is symmetrically connected to the top of the connecting plate 702 through a connecting rod. A movable seat 704 is rotatably connected to one side of the connecting rod 703 through a connecting rod. A fixing plate 705 is fixed at the bottom of the movable seat 704. An elastic telescopic rod 706 is fixed at the bottom of the fixing plate 705. The bottom of the elastic telescopic rod 706 is fixedly connected to the scraper 8.

[0037] In practice, the motor drives the rotating shaft 701 at the top of the base 6 to rotate. The rotating shaft 701 drives the connecting plate 702 fixed at the bottom to rotate synchronously. The connecting plate 702 pulls the moving seat 704 to move back and forth through the connecting rod 703 symmetrically connected at the top. The moving seat 704 drives the fixed plate 705 fixed at the bottom to move synchronously. The fixed plate 705 drives the scraper 8 to move back and forth through the elastic telescopic rod 706 at the bottom, thereby achieving the scraping and leveling of the scum inside the salvage piece 5.

[0038] Please see Figure 6 and Figure 7 As a further embodiment of the present invention, a guide block 707 is fixed on one side of the scraper 8, and a slide rail 710 is symmetrically fixed on one side of the bottom side plate of the base 6. Limiting plates 708 are provided on both sides of the slide rail 710, and limiting blocks 709 are symmetrically staggered between the two limiting plates 708. The contact surfaces of the guide block 707 and the limiting block 709 are both inclined surfaces.

[0039] In practice, when the guide block 707 on one side of the scraper 8 moves back and forth with the scraper 8, it slides along the slide rail 710 on the bottom side plate of the base 6. When the guide block 707 contacts the limit blocks 709 that are symmetrically and staggered on the limit plates 708 on both sides of the slide rail 710, it will move vertically through the cooperation of the inclined plane, thereby driving the scraper 8 to switch up and down, so as to achieve the effect of sticking to the scum when scraping and detaching from the scum when returning.

[0040] Please see Figure 4 and Figure 5 As a further embodiment of the present invention, the base 6 has a cavity that cooperates with the movable seat 704, the connecting plate 702 rotates with the top of the base 6, and the fixing plate 705 slides at the bottom of the base 6.

[0041] In practice, the cavity in the base 6 provides a reciprocating space for the movable seat 704. The motor drives the rotating shaft 701 to rotate the connecting plate 702 at the top of the base 6. The connecting plate 702 drives the movable seat 704 to move in the cavity through the connecting rod 703, which in turn drives the fixed plate 705 at the bottom of the movable seat 704 to slide synchronously at the bottom of the base 6, and finally drives the scraper 8 connected to the elastic telescopic rod 706 to complete the scum scraping action.

[0042] Please see Figure 8 and Figure 9 As a further embodiment of the present invention, the stirring assembly includes a connecting shaft 111 rotatably connected to a rotating shaft 701 via a belt. Two swaying plates 112 are fixed to the outer wall of the connecting shaft 111. A connecting column 113 is rotatably connected between the two swaying plates 112 via a connecting rod. A sliding rod 115 is slidably connected to the connecting column 113. A rotating component 116 is fixed to one end of the sliding rod 115. A turntable 117 is fixed to one end of the rotating component 116. A stirring rod 12 is symmetrically fixed to one end of the turntable 117.

[0043] In practice, the rotating shaft 701 drives the connecting shaft 111 to rotate via a belt. The two swaying plates 112 on the outer wall of the connecting shaft 111 rotate synchronously with it. The swaying plates 112 drive the connecting column 113 to reciprocate via a connecting rod. The connecting column 113 drives the slide rod 115 to slide, which in turn drives the rotating part 116 and the turntable 117 to rotate. Finally, the stirring rod 12, which is symmetrically fixed at one end of the turntable 117, rotates to achieve full mixing of coal water and flocculant.

[0044] Please see Figure 8 As a further embodiment of the present invention, the connecting shaft 111 is connected through the fixed base 10, and the rotating member 116 is connected through the fixed base 10.

[0045] In practice, the connecting shaft 111 passes through the fixed seat 10 and rotates in conjunction with the rotating shaft 701 via a belt, which drives the swaying plate 112 on the outer wall to drive the connecting column 113 and the slide rod 115 in conjunction. At the same time, the rotating part 116 passing through the fixed seat 10 rotates synchronously with the slide rod 115, thereby driving the turntable 117 and the symmetrically fixed stirring rod 12 to rotate, and achieving stable mixing of coal water and flocculant under the support and limitation of the fixed seat 10.

[0046] Please see Figure 9 As a further embodiment of the present invention, a groove 114 is provided on one side of the connecting column 113 to cooperate with the sliding rod 115, and the sliding rod 115 slides in the groove 114.

[0047] In practice, the rotation of the connecting shaft 111 causes the swaying plate 112 to swing, which in turn drives the connecting column 113 to reciprocate. Since a groove 114 that cooperates with the slide rod 115 is provided on one side of the connecting column 113, the slide rod 115 can slide in the groove 114, which converts the reciprocating motion of the connecting column 113 into the linkage of the slide rod 115, thereby driving the rotating part 116, the turntable 117 and the stirring rod 12 to rotate, so as to achieve full mixing of coal water and flocculant.

[0048] Working principle: When using this coal-water treatment waste residue recycling device, changes in coal-water flow rate and treatment volume will cause the sedimentation tank level to rise or fall. Adjusting the height of the feeding point ensures that the agent always falls into the effective mixing zone of the water, avoiding agent splashing when the liquid level is too high and agent directly impacting the sediment at the bottom of the tank when the liquid level is too low. Also, adjusting the height of the scooping position can ensure that the scraper 8 is just in contact with the bottom of the scum layer, thus thoroughly scraping off the scum. Start the motor, which drives the bidirectional lead screw 301 to rotate. The rotation of the bidirectional lead screw 301 drives the two sliders 302 to move bidirectionally through its threads, thereby driving the rotating plates 303 on both sides to rotate. When the rotating plates 303 rotate, the connecting plate 304 connected to them drives the lifting plate 305 to slide in the moving frame 2, thereby driving the connecting seat 4 to move through the lifting plate 305. The scooping part 5 is fixed on one side of the connecting seat 4, thus achieving the effect of adjusting the height of the feeding cylinder 9 and the scooping part 5 in the main body 1.

[0049] When water quality deteriorates, such as a surge in suspended solids, the amount of flocculant added needs to be increased simultaneously. At this time, increased scum on the water surface triggers the motor to start and increase its speed. The motor's forward rotation drives the rotating shaft 701 to rotate forward, which in turn causes the connecting plate 702 to rotate at the top of the base 6. The forward rotation of the connecting plate 702, via the connecting rod 703, moves the movable seat 704 within the cavity of the base 6, thereby moving the fixed plate 705 fixed at the bottom of the movable seat 704. Since the fixed plate 705 is connected to the scraper 8 via the elastic telescopic rod 706, the scraper 8 moves synchronously with the fixed plate 705. Meanwhile, the guide block 707 fixed on one side of the scraper 8 slides at the bottom of the slide rail 710 (elastic telescopic rod). (706 is in a stretched state). When the guide block 707 moves with the scraper 8 to contact the limiting block 709 at the bottom of the limiting plate 708, since the contact surfaces of the guide block 707 and the limiting block 709 are both inclined, the guide block 707 moves vertically as the fixed plate 705 moves horizontally, so that the guide block 707 is located at the top of the slide rail 710. When the guide block 707 slides at the bottom of the slide rail 710, it drives the scraper 8 to scrape the scum accumulated in the retrieval piece 5. The scum is light and easy to stack. If it is not scraped flat, it will form an uneven accumulation area on the water surface. The thick part may exceed the bearing capacity of the scraper 8, and the thin part is easily washed back into the water by the water flow, resulting in missed retrieval.

[0050] At this time, the motor reverses, driving the rotating shaft 701 to reverse as well. The rotation of the rotating shaft 701 drives the connecting plate 702 to reverse, which in turn drives the fixed plate 705, which is fixed at the bottom of the movable seat 704, to move back to its initial position. At this time, the guide block 707 fixed on one side of the scraper 8 slides at the top of the slide rail 710 (the elastic telescopic rod 706 is in a compressed state). This achieves the effect that the scraper 8 does not come into contact with the scum on its return trip after scraping it flat, preventing the return scraper 8 from bringing the scum that has been scraped to the vicinity of the scum collection trough back into the pool, causing secondary pollution. To reduce secondary diffusion and pollution, and to reduce repeated friction between the scraper 8 and hard impurities (such as plastic fragments and shale particles) in the scum, when the guide block 707 moves with the fixed plate 705 to contact the limiting block 709 at the top of the limiting plate 708, since the contact surfaces of the guide block 707 and the limiting block 709 are both inclined, the guide block 707 moves vertically as the fixed plate 705 moves horizontally, so that the guide block 707 is located at the bottom of the slide rail 710, which is convenient for the next scraping of the scum.

[0051] When the rotating shaft 701 rotates forward or backward, it drives the connecting shaft 111 to rotate synchronously via the belt. The rotation of the connecting shaft 111 causes the swaying plate 112 fixed on its outer wall to swing. When the swaying plate 112 swings, it drives the connecting column 113 to reciprocate horizontally via the connecting rod. Since the connecting column 113 has a sliding groove 114 that cooperates with the sliding rod 115 to slide, the sliding rod 115 slides in the sliding groove 114, thereby causing the rotating component 116 fixed to the sliding rod 115 to rotate around the fixed seat 10, which in turn drives the turntable 117 to rotate. The rotating disc 117 drives the symmetrically fixed stirring rods 12 on one side to rotate, thereby agitating the coal-water mixture through the rotating stirring rods 12 and the oscillating shaking plate 112. This ensures that the flocculant added to the sedimentation tank through the feeding cylinder 9 can fully react with the coal-water mixture. The agitation can prevent the local concentration of the agent from being too high, resulting in loose flocs, or too low, resulting in the inability to form flocs. This ensures that the flocculation reaction effect of the entire coal-water mixture is consistent, and that subsequent sedimentation is uniform. If the content of the added flocculant is stable, the rotation speed and the normal frequency are maintained to balance the treatment effect and energy consumption.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
