Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge scraper for sedimentation tanks used in the treatment of fluoride-containing wastewater. Background Technology

[0002] Fluoride-containing wastewater refers to industrial wastewater or polluted water bodies containing excessive fluoride ions (F⁻). Fluoride-containing wastewater sedimentation tanks are key facilities for treating fluoride-containing industrial wastewater, primarily used to separate fluoride precipitates (such as calcium fluoride) formed in the wastewater, achieving solid-liquid separation and fluoride ion removal. By adding reagents such as calcium salts (such as lime, calcium chloride) or aluminum salts (such as polyaluminum chloride), fluoride ions form insoluble precipitates (such as CaF₂ or fluoride-aluminum complexes). The sedimentation tank utilizes gravity settling to separate sludge from clean water. During use, the insoluble precipitates in the sedimentation tank need to be scraped off.

[0003] Existing sludge scrapers for sedimentation tanks mainly consist of scrapers, horizontal position adjustment components, vertical height adjustment components, and supports. Their use has the following drawbacks:

[0004] 1. The horizontal position adjustment component can only adjust the position of the scraper in one direction, and the scraper cannot perform comprehensive sludge removal in the sedimentation tank.

[0005] 2. When lifting the scraper plate after scraping is completed, the weight of the scraper plate increases significantly due to the accumulation of sediment on it. Lifting the scraper plate at this time can easily cause the support frame to be unbalanced and damage the scraper machine.

[0006] This utility model addresses this issue by proposing a slag scraper for sedimentation tanks used in the treatment of fluoride-containing wastewater. The aim is to solve the aforementioned problems by enabling the slag scraper to perform comprehensive slag scraping and cleaning of the sedimentation tank. When the scraper plate is lifted after slag scraping, the entire support frame of the slag scraper is subjected to balanced forces, making the slag scraper less prone to damage. Utility Model Content

[0007] To address the aforementioned shortcomings in the existing technology, this utility model provides a sludge scraper for sedimentation tanks used in the treatment of fluoride-containing wastewater.

[0008] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0009] A sludge scraper for sedimentation tanks used in fluoride-containing wastewater treatment includes a base plate.

[0010] The upper surface of the base plate is provided with a position adjustment component, and a vertical pole is provided above the base plate. The position adjustment component adjusts the position of the vertical pole, and a top plate is provided at the upper end of the vertical pole.

[0011] The top plate includes a fixed plate, a telescopic plate, and a movable plate. The telescopic plate is slidably connected to one end of the fixed plate. A counterweight is provided on the end of the telescopic plate that protrudes from the fixed plate. A connecting rod is provided at the other end of the fixed plate. The movable plate is slidably connected to the connecting rod. A driving component is provided on the upper surface of the fixed plate. The driving component drives the telescopic plate and the movable plate to move synchronously. A lifting plate is provided below the movable plate. A lifting component is provided on the upper surface of the movable plate. The lifting component is connected to the lifting plate via a rope.

[0012] The lifting component includes a support plate, a take-up reel, and a motor. The support plate is disposed opposite to the upper surface of the movable plate, and an opening is provided between the support plate and the movable plate. The take-up reel is rotatably connected between the support plates, and a rope is wound on the take-up reel. The rope is connected to the lifting plate. The motor is provided on the support plate and drives the take-up reel to rotate. A slag scraping component is provided on the lower surface of the lifting plate.

[0013] Furthermore, the position adjustment component includes a second support plate, a screw, a second motor, a guide rail, and a sliding plate. The second support plates are symmetrically arranged on the upper surface of the base plate, and the screw is rotatably connected between the second support plates. The second motor is provided on the second support plate, and the second motor drives the screw to rotate. The guide rail is arranged on the upper surface of the base plate, and the sliding plate is slidably connected to the guide rail. The sliding plate is threadedly connected to the screw, and the lower end of the upright is connected to the sliding plate.

[0014] Furthermore, there are two guide rails, which are symmetrically arranged on both sides of the support plate.

[0015] Furthermore, the driving component includes a two-way cylinder, a connecting plate, and a second connecting rod. The two-way cylinder is mounted on the upper surface of the fixed plate, and the piston rod of the two-way cylinder is connected to the counterweight and the movable plate through the second connecting rod and the connecting plate, respectively.

[0016] Furthermore, the slag scraping component includes a first scraper and a second scraper. The upper end of the first scraper is connected to the lifting plate, and the lower end of the first scraper is provided with a second scraper that curves forward and backward.

[0017] Furthermore, a limiting rod is provided on the upper surface of the lifting plate, and the limiting rod is slidably connected to the movable plate.

[0018] Compared to traditional technologies, the advantages of this utility model are:

[0019] 1. The position adjustment component adjusts the position of the scraper in one direction through the upright and top plate, and the drive component drives the scraper to adjust its position in another direction through the movable plate, so that the scraper can perform comprehensive sludge scraping treatment on the inner wall of the sedimentation tank.

[0020] 2. When the scraper is lifted, the counterweight at the other end of the telescopic plate ensures the force balance at both ends of the top plate. When the scraper is adjusted in another direction, the drive component drives the telescopic plate and the movable plate to move synchronously, and adjusts the counterweight and the scraper to move synchronously, thereby ensuring the force balance of the top plate and preventing the scraper from tilting and being damaged.

An opening is provided between the support plates 9 on the movable plate 5. The take-up reel 10 is rotatably connected between the support plates 9. A rope is wound on the take-up reel 10. The rope is connected to the lifting plate 8. The motor 11 is provided on the support plate 9. The motor 11 drives the take-up reel 10 to rotate. The lower surface of the lifting plate 8 is provided with a slag scraper.

[0031] The slag scraping component includes a first scraper 20 and a second scraper 21. The upper end of the first scraper 20 is connected to the lifting plate 8, and the lower end of the first scraper 20 is provided with a second scraper 21 that curves forward and backward.

[0032] In use, the motor 11 rotates, driving the take-up reel 10 to rotate. The take-up reel 10 winds up and unwinds the rope on it. The cable drives the lifting plate 8 to move up and down. The lifting plate 8 drives the scraper 20 and scraper 21 to move up and down. When the scraper 20 and scraper 21 move downward, they move into the sedimentation tank to scrape the sediment in the sedimentation tank. When the scraper 20 and scraper 21 move upward, they scrape the sediment out of the sedimentation tank.

[0033] Combined with appendix Figure 1-3 The base plate 1 is provided with a position adjustment component on its upper end surface, and a vertical rod 2 is provided above the base plate 1. The position adjustment component adjusts the position of the vertical rod 2.

[0034] The position adjustment component includes a second support plate 12, a screw 13, a second motor 14, a guide rail 15, and a sliding plate 16. The second support plate 12 is symmetrically arranged on the upper surface of the base plate 1. The screw 13 is rotatably connected between the second support plates 12. The second motor 14 is provided on the second support plate 12 and drives the screw 13 to rotate. The guide rail 15 is arranged on the upper surface of the base plate 1, and the sliding plate 16 is slidably connected to the guide rail 15. The sliding plate 16 is threadedly connected to the screw 13, and the lower end of the upright 2 is connected to the sliding plate 16.

[0035] After scraper blade 20 and scraper blade 21 move into the sedimentation tank, motor 2 14 rotates, driving screw 13 between support plates 2 12 to rotate. Screw 13 drives slide plate 16, which is threadedly connected to it, to move. Guide rail 15 guides the movement direction of slide plate 16. Slide plate 16 drives top plate to move through upright 2. Top plate drives scraper blade 20 and scraper blade 21 to move in one direction.

[0036] Combined with appendix Figure 1-2The top plate includes a fixed plate 3, a telescopic plate 4, and a movable plate 5. The telescopic plate 4 is slidably connected to one end of the fixed plate 3. A counterweight 6 is provided on the end of the telescopic plate 4 that protrudes from the fixed plate 3. A connecting rod 7 is provided on the other end of the fixed plate 3. The movable plate 5 is slidably connected to the connecting rod 7. A driving component is provided on the upper surface of the fixed plate 3. The driving component drives the telescopic plate 4 and the movable plate 5 to move synchronously.

[0037] The driving component includes a bidirectional cylinder 17, a connecting plate 18, and a connecting rod 19. The bidirectional cylinder 17 is disposed on the upper end face of the fixed plate 3. The piston rod of the bidirectional cylinder 17 is connected to the counterweight 6 and the movable plate 5 through the connecting rod 19 and the connecting plate 18, respectively.

[0038] The piston rod of the bidirectional cylinder 17 extends and retracts, driving the movable plate 5 to move via the connecting plate 18. The movable plate 5 slides on the connecting rod 19, which guides and limits the direction of movement of the movable plate 5. The movable plate 5 drives the scraper 20 and scraper 21 to move in two mutually perpendicular directions. The scraper 20 and scraper 21 are in contact with the inner surface of the sedimentation tank, performing comprehensive slag scraping treatment on the inner surface of the sedimentation tank. The piston rod of the bidirectional cylinder 17 extends and retracts, driving the counterweight 6 to move via the connecting rod 19. The counterweight 6 drives the telescopic plate 4 to move. The counterweight 6 moves synchronously with the scraper 20 and scraper 21, ensuring the force balance of the top plate and preventing the upright 2 from tilting or shifting, thus avoiding damage to the slag scraper.

[0039] When scraper blade 20 and scraper blade 21 are in contact with the inner surface of the sedimentation tank, scraper blade 20 and scraper blade 21 are lifted to scrape the sediment remaining on them out of the sedimentation tank.

[0040] Example 2

[0041] Combined with appendix Figure 1-3 There are two guide rails 15, which are symmetrically arranged on both sides of the support plate 12.

[0042] The upper end face of the lifting plate 8 is provided with a limiting rod 22, which is slidably connected to the movable plate 5.

[0043] Based on Embodiment 1, two symmetrically arranged guide rails 15 ensure the stability of the sliding plate 16's movement. The limiting rod 22 on the upper surface of the lifting plate 8 slides on the movable plate 5 when the lifting plate 8 moves up and down, preventing the lifting plate 8 from shaking during the lifting process.

[0044] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
