Technical Field

[0001] The invention relates to the technical field of municipal sewage treatment equipment, and in particular to a sewage treatment device for municipal water supply and drainage. Background Art

[0002] Municipal water supply and drainage refers to the infrastructure system that provides water supply and drainage services to residents, industries, and commerce within the city. It is part of municipal engineering. Municipal sewage contains a large amount of organic matter, such as protein, carbohydrates, etc., which are easy to corrupt. When the organic matter combines with the sludge in the sewage, the viscosity is high and it is easy to accumulate in the lower part of the treatment device, making it difficult to remove.

[0003] A Chinese patent with patent publication number CN200998613Y discloses a sewage treatment peripheral scraper and suction machine with a new type of sludge collecting and suction plate. The new type of sludge collecting and suction plate adopts a "human" shaped slope in the horizontal direction, so that the sludge automatically gathers along the slope and flows to the pipe mouth; a new type of sludge collecting and suction plate is also provided with a "human" shaped slope on the top surface in the vertical direction, so that the accumulated sludge automatically gathers to the pipe mouth along the upper slope.

[0004] Most of the existing sewage treatment devices use a sludge suction machine to extract the accumulated sludge. Although the device can extract the sludge on the upper part very well, the sludge in contact with the device at the bottom has a high viscosity, so it is difficult for the device to completely remove the sludge, resulting in sludge residue, affecting the sewage treatment effect and increasing the difficulty of maintenance of the device.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figure 1-6As shown, a sewage treatment device for municipal water supply and drainage described in this embodiment includes a treatment tank 1, and a water outlet pipe 8 is provided at the lower side of the treatment tank 1; a grid plate 2, which is obliquely arranged at the upper part of the treatment tank 1, and the grid plate 2 is used to filter impurities with larger diameters in the sewage. When the sewage passes through the grid plate 2, the impurities with larger diameters are blocked by the grid plate 2, and then slide downward along the grid plate 2. The sewage passes through the grid plate 2 and enters the treatment tank 1 for the next purification process; a mud suction component, which is provided The mud suction assembly includes a mud suction device 14 and a guide rail 13, the guide rail 13 is arranged at the lower part of the treatment tank 1, and the mud suction device 14 is arranged on the guide rail 13. When the mud is sucked, the mud suction device 14 is controlled to reciprocate along the guide rail 13, and the mud enters the mud suction device 14 under the attraction of the mud suction device 14. A heat soaking plate 17 is provided on the inner wall of the bottom surface of the treatment tank 1, and a heating wire 18 is provided at the lower part of the heat soaking plate 17. The heating wire 18 is coiled in an S shape at the lower part of the heat soaking plate 17. The treatment tank 1 has an ultrasonic vibrator 16 embedded below the inner walls on both sides thereof. The ultrasonic vibrator 3 is located below the outlet pipe 8 so as to retain some water inside the treatment tank 1 so that the ultrasonic wave can fully propagate in the mixture of sludge and water and enhance the cavitation effect of the ultrasonic wave. The cavitation effect of the ultrasonic wave will generate tiny bubbles in the liquid. These bubbles release high energy when they collapse and can destroy the structure between the sludge particles, making the sludge easier to flow and remove. The heating wire 18 is used to heat the sludge at the bottom of the treatment tank 1. When the temperature rises, the viscosity of the water decreases, so that the viscosity of the sludge as a whole also decreases. The sludge contains a large amount of water. The enhanced fluidity of the water will reduce the overall viscosity of the sludge, thereby making the sludge at the bottom of the treatment tank 1 easier to be adsorbed by the sludge suction device 14. The synergistic effect of the heating wire 18, the heat spreader 17 and the ultrasonic vibrator 16 greatly reduces the viscosity of the sludge at the bottom of the treatment tank 1, making the sludge easier to be adsorbed by the sludge suction component, greatly improving the sludge removal effect and reducing the difficulty of maintenance of the device.

[0030] One side of the grid plate 2 is hinged to the treatment tank 1, and the other side is connected to the treatment tank 1 through an elastic component 4. The elastic component 4 includes a telescopic rod 41 and a spring 42. The upper part of the telescopic rod 41 is connected to the grid plate 2, and the lower part is fixedly connected to the treatment tank 1. The spring 42 is arranged around the outer side of the telescopic rod 41. A vibrator 3 is fixedly arranged on the upper part of the grid plate 2, and the vibrator 3 is arranged on the side of the grid plate 2 close to the elastic component 4. An inclined sewage trough 5 is arranged on the side of the treatment tank 1 away from the elastic component 4. When the sewage passes through the grid plate 2, part of the impurities in the sewage are blocked by the grid plate 2, and then slide down along the grid plate 2, and the vibrator 3 is started. Under the combined action of gravity, water impact force and vibration force, the impurities slide down into the sewage trough 5 below the grid plate 2. By setting the inclined grid plate 2, the elastic component 4 and the vibrator 3, the residual impurities on the upper part of the grid plate 2 are greatly reduced, the clogging of the grid plate 2 is avoided, and the maintenance cost of the device is further reduced.

[0031] The mud suction assembly also includes a screw rod 12 and a mud suction hose 15. The screw rod 12 is rotatably arranged inside the treatment tank 1 and penetrates the mud suction device 14. A motor 9 is provided on the outside of the treatment tank 1 through a bracket 10. One end of the screw rod 12 penetrates the side wall of the treatment tank 1 and is connected to the motor 9. The mud suction hose 15 is connected and arranged on the upper part of the mud suction device 14. A mud suction pump 6 is provided on the side of the treatment tank 1. The upper end of the mud suction hose 15 penetrates the side wall of the treatment tank 1 and is connected to the mud suction pump 6. A mud outlet 7 is provided on the side of the mud suction pump 6.

[0032] How it works

[0033] When sewage treatment is carried out, the sewage is output to the top of the grid plate 2 through the water inlet pipe 11. The sewage passes through the grid plate 2 during the falling process. Some impurities in the sewage are blocked by the grid plate 2, and then the sewage slides down along the grid plate 2. The vibrator 3 is started. Under the combined effect of gravity, water impact force and vibration force, the impurities slide down to the sewage trough 5 below the grid plate 2. The sewage enters the treatment tank 1. The sewage is left to stand for a period of time. The sludge in the sewage settles at the bottom of the treatment tank 1. The outlet pipe 8 is opened to output the precipitated sewage. The electric heating wire 18 is started. The heat output by the electric heating wire 18 is uniformly heated after passing through the heat plate 17. The sludge at the bottom of the treatment tank 1 is evenly heated. When the sludge temperature increases, the viscosity of the water decreases, so that the overall viscosity of the sludge also decreases. The ultrasonic vibrator 16 is started. The cavitation effect of the ultrasonic wave will produce tiny bubbles in the liquid. These bubbles release high energy when they collapse, which can destroy the structure between the sludge particles, making the sludge easier to flow and remove. Under the combined action of the two, the adhesion of the sludge is greatly reduced. The motor 9 is started to drive the sludge suction device 14 to reciprocate along the guide rail 13, and the sludge suction pump 6 is started. Under the gravitational force of the sludge suction pump 6, the sludge passes through the sludge suction device 14 and the sludge suction hose 15 in turn and is discharged from the sludge outlet 7.
