Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, and in particular to a sludge conditioning and mixing device. Background Art

[0002] Sludge has a high water content. The premise of sludge treatment and resource utilization is to pre-treat the sludge to reduce the amount of water, that is, to remove a large amount of water from the sludge. The current conventional process is to add sludge conditioning agents, efficiently mix the liquid sludge and the agents to form larger flocs, and to condition and modify the sludge to reduce the difficulty of dehydration, and then use a sludge dehydrator for dehydration.

[0003] The existing rapid mixing device for sludge conditioning (Announcement No.: CN210796184U) has at least the following disadvantages:

The structure is simple and the entire structure occupies a small space. The flocculant and the sludge are mixed by introducing the first flocculant introduction tube and the second flocculant introduction tube. Since the flocculant in the above patent is added to the inside of the mixing barrel at one time, the flocculant needs to be stirred for a long time before it can enter the inside of the sludge, resulting in more time required to mix the flocculant when conditioning the sludge, which increases the time for sludge conditioning treatment.

[0032] Reference Figure 1-Figure 10A sludge conditioning and mixing device comprises a base 1 and a mixing barrel 4, wherein the mixing barrel 4 is arranged above the base 1, and a plurality of annular tubes 11 are fixedly installed at equal intervals on the outer surface of the mixing barrel 4, wherein the cross section of the annular tube 11 is Q-shaped, and the discharge end of the annular tube 11 passes through the inner wall of the mixing barrel 4 and is connected with the interior thereof, and a bottom plate 30 is fixedly installed on the inner wall of the annular tube 11 near the discharge end, and a discharge hole 14 is opened through the lower surface of the middle position of the bottom plate 30, and a fixed cylinder 18 is fixedly installed on the upper surface of the middle position of the bottom plate 30, and a hexagonal cylinder 24 is slidably inserted in the middle position of the upper surface of the fixed cylinder 18, and a horn plug 15 is fixedly installed on the bottom end of the hexagonal cylinder 24 through the discharge hole 14, and the horn plug 15 is matched with the discharge hole 14, and a second slide plate 20 is fixedly installed on the top of the hexagonal cylinder 24, and a first spring 22 is sleeved on the outer surface of the hexagonal cylinder 24, and the first spring 22 is arranged between the second slide plate 20 and the fixed cylinder 18, and the circumferential direction of the lower surface of the second slide plate 20 is fixedly installed at equal intervals. There are multiple top columns 21, a feed pipe 12 is fixedly installed on the circumferential outer surface of the fixed cylinder 18, the bottom end of the feed pipe 12 penetrates the inner wall of the fixed cylinder 18 and is connected with the interior thereof, the top end of the feed pipe 12 penetrates the outer surface of the annular tube 11, the feed port of the feed pipe 12 is threadedly connected with a conditioning agent bottle 13, the feed pipe 12 is tilted, a slide cylinder 25 is slidably installed on the inner wall of the hexagonal cylinder 24, the top end of the slide cylinder 25 penetrates the upper surface of the second slide plate 20 and is fixedly installed with the first slide plate 19, the first slide plate A plurality of top columns 21 are also equidistantly fixedly installed on the circumferential direction of the lower surface of 19. A second spring 23 is sleeved on the circumferential outer surface of the slide cylinder 25. The second spring 23 is arranged between the first slide plate 19 and the second slide plate 20. A steel ball 17 is slidably installed on the inner wall of the annular tube 11. The steel ball 17 abuts against the upper surface of the first slide plate 19. The compression distance between the second spring 23 and the first spring 22 is limited by the top column 21. At the same time, the first slide plate 19 drives the second slide plate 20 to move downward through the top column 21.

[0033] The movement of the mixing barrel 4 drives the annular tube 11 to move. When the annular tube 11 moves to the highest point, the steel ball 17 will slide onto the upper surface of the first slide plate 19. The gravity of the steel ball 17 drives the first slide plate 19 to move downward, so that the first slide plate 19 drives the second slide plate 20 to move downward through the top column 21, and the second slide plate 20 drives the hexagonal tube 24 to move downward, so that the hexagonal tube 24 drives the horn plug 15 to move downward and leave the discharge hole 14. At this time, the flocculant inside the conditioning agent bottle 13 enters the interior of the fixed cylinder 18 through the feed pipe 12, and then falls into the interior of the mixing barrel 4 through the discharge hole 14. When the annular tube 11 rotates to another position, the horn plug 15 blocks the discharge hole 14 again through the force of the first spring 22. Through the present device, when the sludge is turned over in the mixing barrel 4, the flocculant can be quantitatively and intermittently added to the sludge, so as to avoid the one-time addition of the flocculant, which requires a long time of stirring to make the flocculant and the sludge evenly mixed, thereby greatly reducing the time of sludge conditioning treatment.

[0034] In this embodiment, a limiting groove 29 is provided on the circumferential outer surface of the slide cylinder 25 close to the first slide plate 19, and a limiting block is fixedly installed on the inner wall of the hexagonal cylinder 24. The limiting block and the inner wall of the limiting groove 29 are slidably installed. The cooperation between the limiting block and the limiting groove 29 ensures that the slide cylinder 25 will not rotate.

[0035] In this embodiment, a rotating rod 26 is rotatably installed on the inner wall of the hexagonal tube 24 near the bottom end, and the bottom end of the rotating rod 26 passes through the lower surface of the horn plug 15 and is fixedly installed with a scraper 16. The scraper 16 is flush with the lower surface of the horn plug 15 and the bottom plate 30. The top end of the rotating rod 26 passes through and is inserted into the interior of the slide cylinder 25 and is slidably installed on its inner wall. Two driving columns 28 are symmetrically fixedly installed on the circumferential outer surface of the rotating rod 26 near the top end, and two spiral grooves 27 are penetrated through the circumferential outer surface of the slide cylinder 25 near the bottom end. The two driving columns 28 are slidably installed on the inner walls of the two spiral grooves 27 respectively.

[0036] When the annular tube 11 moves below the horizontal position, the steel ball 17 will enter the inner ring of the annular tube 11. At this time, the first slide plate 19 and the second slide plate 20 move upward under the action of the first spring 22 and the second spring 23, and the horn plug 15 blocks the discharge hole 14 again to prevent the sludge from entering the fixed cylinder 18 through the discharge hole 14 and blocking it when the sludge is rotated to the position; when the steel ball 17 slides to the upper surface of the first slide plate 19, it first drives the first slide plate 19 to move downward, and the first slide plate 19 drives the slide cylinder 25 to move downward, and the slide cylinder 25 drives the rotating rod through the cooperation of the spiral groove 27 and the driving column 28. 26 rotates, so that the rotating rod 26 drives the scraper 16 to clean the lower surfaces of the horn plug 15 and the bottom plate 30. When the steel ball 17 gradually leaves the upper surface of the first slide plate 19, the first spring 22 will first drive the second slide plate 20 to reset, and the scraper 16 will be re-flattened with the lower surface of the bottom plate 30, and then the second spring 23 drives the first slide plate 19 to reset. At this time, the scraper 16 cleans the lower surfaces of the horn plug 15 and the bottom plate 30 again. This device ensures that the lower surfaces of the horn plug 15 and the bottom plate 30 will not be adhered to sludge, thereby preventing sludge from entering the inside of the discharge hole 14 and causing the discharge hole 14 to be blocked.

[0037] In this embodiment, two fixed shafts 5 are symmetrically fixedly installed on the upper surface of the base 1, and two rollers 6 are rotatably installed on the outer surfaces of the two fixed shafts 5. Two rolling grooves are provided on the circumferential outer surface of the mixing barrel 4, and the two rollers 6 at the adjacent ends are rollingly installed with the inner walls of the rolling grooves. A driving motor 7 is fixedly installed on the upper surface of the base 1, and a driving gear 8 is fixedly installed on the output end of the driving motor 7. A ring gear 9 is fixedly installed on the circumferential outer surface of the mixing barrel 4, and the driving gear 8 is meshed with the ring gear 9.

[0038] The driving motor 7 drives the driving gear 8 to rotate, so that the driving gear 8 drives the ring gear 9 to rotate, and the ring gear 9 drives the mixing barrel 4 to rotate, so that the sludge moves in the mixing barrel 4, and the spiral stirring blades 10 make the sludge turn over, thereby accelerating the mixing speed of the sludge.

[0039] In this embodiment, two brackets 2 are symmetrically fixedly installed on the upper surface of the base 1 near the feed end of the mixing barrel 4, a feed hopper 3 is fixedly installed between the two brackets 2, and the discharge end of the feed hopper 3 is arranged inside the feed end of the mixing barrel 4. A plurality of spiral stirring blades 10 are fixedly installed at equal intervals on the inner wall of the mixing barrel 4. The sludge is conveyed to the inside of the feed hopper 3 through an external conveyor belt, and slides into the inside of the mixing barrel 4 through the feed hopper 3. When discharging is required, the mixing barrel 4 is rotated in the opposite direction so that the mixed sludge flows out to the inside of the collection box along the rotation direction of the spiral stirring blades 10 and enters the subsequent treatment process.

[0040] In this embodiment, the elastic force of the first spring 22 is greater than the elastic force of the second spring 23, ensuring that when the steel ball 17 gradually leaves the upper surface of the first slide plate 19, the first spring 22 will first drive the second slide plate 20 to reset, the scraper 16 will be re-flattened with the lower surface of the bottom plate 30, and then the second spring 23 will drive the first slide plate 19 to reset, and at this time the scraper 16 will once again clean the lower surface of the speaker plug 15 and the bottom plate 30.

[0041] In this embodiment, it should be noted that when the discharge hole 14 is sealed, excessive flocculants will be inside the fixed cylinder 18 or inside the conditioning agent bottle 13. The fixed cylinder 18 is in a sealed state and no flocculants will leak out.

[0042] It should be noted that when the present invention is in use, the operator manually rotates the mixing barrel 4 so that it drives the annular tube 11 to rotate to a roughly horizontal position. Then, the operator manually connects the conditioner bottle 13 containing flocculant to the feed end of the feed tube 12 through a thread, so as to facilitate the subsequent addition of flocculant to the interior of the mixing barrel 4. The sludge is conveyed to the interior of the feed hopper 3 through an external conveyor belt, and slides into the interior of the mixing barrel 4 through the feed hopper 3. The driving motor 7 drives the driving gear 8 to rotate, so that the driving gear 8 drives the annular gear 9 to rotate, and the mixing barrel 4 is driven to rotate through the annular gear 9, so that the sludge is mixed and moved inside the mixing barrel 4, and the spiral stirring blades 10 are used to turn the sludge, thereby accelerating the mixing speed of the sludge. The movement of the mixing barrel 4 drives the annular gear 9 to rotate. The annular tube 11 moves. When the annular tube 11 moves to the highest point, the steel ball 17 will slide to the upper surface of the first slide plate 19. The gravity of the steel ball 17 drives the first slide plate 19 to move downward, so that the first slide plate 19 drives the second slide plate 20 to move downward through the top column 21. The second slide plate 20 drives the hexagonal tube 24 to move downward, so that the hexagonal tube 24 drives the horn plug 15 to move downward and leave the discharge hole 14. At this time, the flocculant inside the conditioning agent bottle 13 enters the interior of the fixed cylinder 18 through the feed pipe 12, and then falls into the interior of the mixing barrel 4 through the discharge hole 14. When the annular tube 11 rotates to another position, the horn plug 15 blocks the discharge hole 14 again through the force of the first spring 22. The device can be used in When the mixing barrel 4 turns over the sludge, the flocculant is added to the sludge intermittently and quantitatively to avoid adding the flocculant all at once, which results in a longer stirring time to evenly mix the flocculant and the sludge, greatly reducing the time for sludge conditioning treatment; when the annular tube 11 moves below the horizontal position, the steel ball 17 will enter the inner ring of the annular tube 11. At this time, the first slide plate 19 and the second slide plate 20 move upward under the action of the first spring 22 and the second spring 23, and the horn plug 15 blocks the discharge hole 14 again to prevent the sludge from entering the fixed tube 18 through the discharge hole 14 and blocking it when it is rotated to the position of the sludge; when the steel ball 17 slides to the upper surface of the first slide plate 19, it first drives the first slide plate 19 to move downward, and the first slide plate 19 drives the slide 25 to move downward, and the slide 25 drives the rotating rod 26 to rotate through the cooperation of the spiral groove 27 and the driving column 28, so that the rotating rod 26 drives the scraper 16 to clean the lower surfaces of the horn plug 15 and the bottom plate 30. When the steel ball 17 gradually leaves the upper surface of the first slide plate 19, the first spring 22 will first drive the second slide plate 20 to reset, and the scraper 16 will be re-flattened with the lower surface of the bottom plate 30, and then the second spring 23 drives the first slide plate 19 to reset. At this time, the scraper 16 once again cleans the lower surfaces of the horn plug 15 and the bottom plate 30. This device ensures that the lower surfaces of the horn plug 15 and the bottom plate 30 will not adhere to sludge, thereby preventing sludge from entering the inside of the discharge hole 14 and causing the discharge hole 14 to be blocked.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
