Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sewage treatment equipment, specifically a high-concentration brine treatment overflow tank cleaning device. Background Technology
[0002] The vertical circular grit chamber has a circular plan view, with water entering from the bottom and flowing upwards. Water exits through an overflow weir around the upper perimeter of the chamber. The upward flow velocity of the water is 0.02-0.05 m / s, the residence time is 2-3.5 min, and the hydraulic load is 110-130 cubic meters / (square meter·hour). Sand is removed by gravity or mechanical means, 1-3 times a day. The effluent is discharged through an overflow weir around the perimeter, and sand is removed manually or mechanically. This type of grit chamber occupies a relatively small area, but if the inclination angle of the central sand-collecting cone is too small, sand removal becomes more difficult.
[0003] Grit chambers, also known as overflow tanks, are used for the physical treatment of wastewater through overflow sedimentation. However, the slow flow rate of the wastewater leads to the growth of moss inside the overflow tank and the effluent channel, making cleaning difficult. Furthermore, manual cleaning can result in slips and falls due to the wetness, requiring machine shutdowns. The cleaning process is time-consuming and labor-intensive. Therefore, a self-cleaning device is proposed to enable online cleaning of the bottom of the tank and the effluent channel. Utility Model Content
[0004] The purpose of this invention is to provide a high-concentration brine treatment overflow tank cleaning device to solve the problems mentioned in the background art.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a high-concentration brine treatment overflow tank cleaning device includes an overflow tank 1. The overflow tank 1 has a central cylinder 4 and an outlet channel 2 inside. A rotatable water collection bridge 5 is constructed between the overflow tank 1 and the central cylinder 4. The water collection bridge 5 is equipped with a high-pressure water pump 19, a delivery pipeline 20, a spray pipeline 21, and high-pressure nozzles 22. One end of the delivery pipeline 20 extends into the overflow tank 1, and the other end is fitted with a spray pipeline 21 extending into the inner circumference of the outlet channel 2. The spray pipeline 21 is equipped with multiple high-pressure nozzles 22 that spray high-pressure water onto the inner wall of the outlet channel 2. The high-pressure water pump 19 is installed on the delivery pipeline 20. A filter can be installed at one end of the delivery pipeline 20 inside the overflow tank 1 to prevent impurities from entering and contaminating the clear water in the outlet channel 2 or clogging the high-pressure nozzles 22. The water collection bridge 5 can... The top of the overflow tank 1 rotates and moves. During the rotation, the water collection bridge 5 sprays water onto the outlet channel 2 through the high-pressure nozzle 22. If the outlet channel 2 is not cleaned for a long time, moss will grow inside. The high-pressure water sprayed by the high-pressure nozzle 22 treats the moss. The bottom of the outlet channel 2 outputs sewage through the drainage pipe 7. The drainage pipe 7 is connected to the inlet pipe 13 by a three-way valve and a return pipe 23. The moss peeled off from the outlet channel 2 is discharged from the drainage pipe 7 with the water flow. The three-way valve is adjusted so that the wastewater flows back to the inlet pipe 13 through the return pipe 23. The high-pressure water pump 19 cleans intermittently. During the cleaning operation of the high-pressure water pump 19, the three-way valve switches the water path to the return pipe 23. When the high-pressure water pump 19 stops, the sewage is discharged through the other end of the drainage pipe 7, thus realizing the cleaning of the overflow tank of the outlet channel 2.
[0024] In a preferred embodiment, an inclined scraper 16 is installed on the overflow tank 1 via a short support 15. The scraper 16 is lower than the overflow height. A baffle plate 17 is provided inside the outlet channel 2. A foam guide channel 6 is provided on the outlet channel 2 with one end located inside the baffle plate 17. The other end of the foam guide channel 6 extends to the outside of the overflow tank 1. The baffle plate 17, as the main structure for blocking floating objects, extends its bottom below the liquid surface, causing floating objects above the liquid surface to be blocked. Under the operation of the scraper 16, the floating objects are collected and pushed out from the foam guide channel 6, removing the floating objects on the liquid surface.
[0025] In a preferred embodiment, an inclined cleaning plate 9 is installed on the overflow tank 1 via a long support 10. The cleaning plate 9 is equipped with a steel brush that contacts the bottom wall of the overflow tank 1. The cleaning plate 9 is also equipped with casters 11. An annular roller conveyor 18 is provided on the inner bottom wall of the overflow tank 1, and the casters 11 are located inside the roller conveyor 18. The main function of the cleaning plate 9 is to clean the sediment and moss at the bottom of the tank, scraping the sediment and moss to the sewage pipe 8 of the overflow tank 1 for discharge. The cleaning plate 9 has a certain weight and will cut the water flow during movement, making it difficult to fix its position and prone to hitting the bottom. Therefore, casters 11 are added to prevent the cleaning plate 9 from hitting the bottom.
[0026] In a preferred embodiment, a downwardly extending guide tube 3 is installed at the bottom of the water collection bridge 5, the central tube 4 is connected to the water inlet pipe 13, the bottom of the overflow pool 1 is connected to the sewage discharge pipe 8, and the overflow pool 1 is connected to the central tube 4 through the ring bracket 12 to reinforce the central tube 4 and improve its stability.
