Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for biochemical treatment ponds, specifically a sedimentation and cleaning device for industrial wastewater biochemical treatment ponds. Background Technology

[0002] Industrial wastewater biological treatment ponds are specifically designed to treat wastewater from industrial production processes. This wastewater typically contains high concentrations of organic matter, nitrogen, phosphorus, and other pollutants. Utilizing the metabolic activity of microorganisms, these ponds effectively remove pollutants from the wastewater, reducing indicators such as chemical oxygen demand (COD) and biological oxygen demand (BOD) in the water.

[0003] During use, existing biological treatment tanks contain a large amount of sludge and impurities. These impurities settle and adhere to the bottom and inner walls of the tank, requiring regular cleaning. Usually, a sludge pump is used to remove the sediment and sludge from the tank. However, in actual use, the sludge and impurities adhere to the bottom and inner walls of the tank, making direct suction difficult and resulting in poor cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a sedimentation and cleaning device for industrial wastewater biochemical treatment tanks, in order to solve the problem in the prior art that sludge and impurities adhere to the bottom and inner wall of the tank during actual use, making direct suction difficult and resulting in poor cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation and cleaning device for an industrial wastewater biochemical treatment tank, comprising a biochemical treatment tank body, a cleaning structure provided on the top of the biochemical treatment tank body, the cleaning structure comprising four No. 1 fixed seats, the four No. 1 fixed seats being arranged in pairs, and a screw being rotatably installed between each pair of No. 1 fixed seats. A movable plate is threadedly connected to the outer side of each of the two screws, and the two movable plates are disposed on the top of the biochemical treatment tank body and slide in contact with the biochemical treatment tank body. A first scraper is fixedly installed on one side of each of the two movable plates, and the two first scrapers are respectively disposed on the left and right sides inside the biochemical treatment tank body and slide in contact with the biochemical treatment tank body. The movable plates disposed on the top of the biochemical treatment tank body and sliding in contact with it can be limited by the biochemical treatment tank body to ensure that the movable plates can move stably without rotation when the screws rotate.

[0006] Preferably, a second scraper is fixedly installed at the bottom of the two first scrapers. The second scraper is located at the bottom inner side of the biochemical treatment tank body and slides in contact with the biochemical treatment tank body. Four No. 2 fixing seats are fixedly installed on the top of the biochemical treatment tank body. The four No. 2 fixing seats are in pairs. A connecting shaft is rotatably installed between each pair of No. 2 fixing seats. The top of the second scraper is designed with a slope, which allows the scraped sediment to slide off the slope and prevents the sediment from accumulating on the top of the second scraper.

[0007] Preferably, one end of one of the screws passes through one of the first fixing seats and is fixedly installed with a first bevel gear, and one end of one of the connecting shafts passes through one of the second fixing seats and is fixedly installed with a third bevel gear, wherein the first bevel gear and the third bevel gear are meshed together.

[0008] Preferably, two ends of the other screw are respectively fixedly installed with two No. 1 fixing seats and No. 2 bevel gears, and the other ends of the two connecting shafts are respectively fixedly installed with two No. 2 fixing seats and No. 4 bevel gears, and the two No. 2 bevel gears are respectively meshed with the two No. 4 bevel gears.

[0009] Preferably, a first gear is fixedly installed on the outer side of each of the two connecting shafts, and a movable rack is meshed with the outer side of each of the two first gears. A third scraper is fixedly installed at the bottom of each of the two movable racks. Limiting plates are fixedly installed on the front and rear sides of the interior of the biochemical treatment tank body. The two movable racks pass through the two limiting plates respectively and slide in contact with the two limiting plates respectively. The sliding contact between the movable racks and the limiting plates can effectively limit the movable racks and prevent the movable racks from deviating.

[0010] Preferably, a forward and reverse motor is fixedly installed on one side of one of the first fixing seats, and the output end of the forward and reverse motor passes through one of the first fixing seats and is fixedly connected to one of the screws.

[0011] Preferably, two collection containers are fixedly installed on the top of the biochemical treatment tank body, and two suction pumps are fixedly installed on one side of the collection containers. A delivery pipe is fixedly installed at one end of each of the two suction pumps. The two delivery pipes are respectively connected to the collection containers through the two suction pumps. A corrugated hose is fixedly installed at one end of each of the two delivery pipes. The interior of the third scraper is hollow, and several suction grooves are opened at the bottom of the third scraper. One end of each of the two corrugated hoses is fixedly installed on the top of the third scraper and connected to the interior of the third scraper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application uses a forward and reverse motor to drive one screw to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the third bevel gear to rotate, which in turn drives the connecting shaft to rotate, which in turn drives the fourth bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the other screw to rotate, thereby moving two moving plates. This causes the two first scrapers and the second scraper at the bottom to move accordingly, effectively scraping off the sediment and attached materials on the inner bottom and the inner walls of the left and right sides of the biochemical treatment tank, facilitating the subsequent collection and treatment of the sediment and improving the practicality of the device.

[0014] 2. This application uses another screw to drive another No. 2 bevel gear to rotate, which in turn drives another No. 4 bevel gear to rotate, thereby driving another connecting shaft to rotate. As the two connecting shafts rotate, they will drive the No. 1 gear to rotate, which in turn drives the two moving racks to move, thereby driving the two third scrapers to move downwards. This effectively scrapes away the sediment and attachments on the inner walls of the front and rear sides of the biochemical treatment tank, thus cleaning and scraping off the sediment and attachments inside the biochemical treatment tank, further improving the effectiveness of the device.

[0023] Two first scrapers 5 are fixedly installed at the bottom of the second scraper 6. The second scraper 6 is located at the bottom of the inner side of the biochemical treatment tank body 1 and slides in contact with the biochemical treatment tank body 1. Four second fixing seats 7 are fixedly installed on the top of the biochemical treatment tank body 1. The four second fixing seats 7 are in pairs, and a connecting shaft 8 is rotatably installed between each pair of second fixing seats 7.

[0024] One end of one screw 3 passes through one of the first fixing seats 2 and is fixedly installed with a first bevel gear 901. One end of one connecting shaft 8 passes through one of the second fixing seats 7 and is fixedly installed with a third bevel gear 1001. The first bevel gear 901 and the third bevel gear 1001 are meshed and connected.

[0025] The other screw 3 has two ends that pass through two No. 1 fixed seats 2 and are fixedly installed with No. 2 bevel gears 9. The other ends of the two connecting shafts 8 pass through two No. 2 fixed seats 7 and are fixedly installed with No. 4 bevel gears 10. The two No. 2 bevel gears 9 are respectively meshed with the two No. 4 bevel gears 10.

[0026] A first gear 11 is fixedly installed on the outer side of each of the two connecting shafts 8. A movable rack 12 is meshed with the outer side of each of the two first gears 11. A third scraper 13 is fixedly installed at the bottom of each of the two movable racks 12. Limiting plates 14 are fixedly installed on the front and rear sides of the interior of the biochemical treatment tank body 1. The two movable racks 12 pass through the two limiting plates 14 respectively and slide in contact with the two limiting plates 14 respectively.

[0027] One of the fixed bases 2 is fixedly mounted on one side with a forward and reverse motor 15. The output end of the forward and reverse motor 15 passes through one of the fixed bases 2 and is fixedly connected to one of the screws 3.

[0028] Two collection containers 16 are fixedly installed on the top of the biochemical treatment tank body 1. Two suction pumps 17 are fixedly installed on one side of the collection containers 16. A delivery pipe 18 is fixedly installed at one end of each of the two suction pumps 17. The two delivery pipes 18 are connected to the collection containers 16 through the two suction pumps 17 respectively. A corrugated hose 19 is fixedly installed at one end of each of the two delivery pipes 18. The interior of the third scraper 13 is hollow. Several suction grooves are opened at the bottom of the third scraper 13. One end of each of the two corrugated hoses 19 is fixedly installed on the top of the third scraper 13 and connected to the interior of the third scraper 13.

[0029] It should be noted that this utility model is a sedimentation and cleaning device for an industrial wastewater biochemical treatment tank. When in use, the forward and reverse motor 15 is started. The specific model of the forward and reverse motor 15 is not described, but is based on the compatible equipment. The forward and reverse motor 15 will drive one of the screws 3 to rotate, thereby driving the first bevel gear 901 to rotate, which in turn drives the third bevel gear 1001 to mesh and rotate, thereby driving one of the connecting shafts 8 to rotate, which in turn drives one of the fourth bevel gears 10 to rotate, which in turn drives one of the second bevel gears 9 to mesh and rotate, thereby driving the other screw 3 to rotate, thereby driving the two moving plates 4 to move, thereby causing the two first scrapers 5 and the second scraper 6 at the bottom to move, so as to effectively scrape off the sediment and attached materials on the inner bottom and the inner walls of the left and right sides of the biochemical treatment tank body 1, which facilitates the subsequent collection and treatment of the sediment and attached materials, and improves the practicality of the device.

[0030] When cleaning the sediment and deposits on the inner bottom and left and right inner walls of the biochemical treatment tank body 1, another screw 3 will drive another second bevel gear 9 to rotate, which in turn drives another fourth bevel gear 10 to rotate, thereby driving another connecting shaft 8 to rotate. As the two connecting shafts 8 rotate, they will drive the first gear 11 to rotate, which will drive the two moving racks 12 to move, thereby driving the two third scrapers 13 to move downward, thus effectively scraping off the sediment and deposits on the front and rear inner walls of the biochemical treatment tank body 1, thereby cleaning and scraping off the sediment and deposits inside the biochemical treatment tank body 1, further improving the effectiveness of the device.

[0031] When the sediment inside the biochemical treatment tank body 1 is scraped off, it will be pushed to the bottom of the biochemical treatment tank body 1 near the front and rear sides by the second scraper 6 during the moving cleaning process. At this time, the two third scrapers 13 are moved down to the top of the sediment, and then the four suction pumps 17 are started. The suction force is used to draw the sediment from the inside of the biochemical treatment tank body 1 into the collection container 16 through the delivery pipe 18, the corrugated hose 19 and the suction groove at the bottom of the third scraper 13, so that the staff can carry out unified treatment later.
