Description

Technical Field

[0001] The utility model relates to the technical field of tail water sand filtration treatment equipment, in particular to a tail water sand filtration treatment device for a sewage plant. Background Art

[0002] Sand filtration is a water filtration process that uses natural quartz sand, usually manganese sand and anthracite as filter media. The sand particle size is generally 0.5-1.2mm, and the non-uniformity coefficient is 2. It is often used for water treatment after clarification (sedimentation) treatment or deep treatment of sewage after secondary treatment. Different filter layer thicknesses and filtration speeds can be used according to the requirements of raw water and effluent water quality. The main function is to intercept large molecular solid particles and colloids in the water to clarify the water.

[0003] For example, in the patent number CN 216320491 U, it is announced that "the utility model relates to the technical field of sand filters, and discloses a sand filter for wastewater treatment, including a cylinder, a water distribution pipe is arranged inside the cylinder, the bottom end of the water distribution pipe is fixedly connected with a water distribution bottom pipe, the lower part of the outer surface of the water distribution pipe is fixedly connected with a water distribution pipe, and the side of the cylinder is fixedly sleeved with a water inlet pipe". In the text, a filter cloth is arranged inside the drain pipe, so that a small amount of sand and gravel carried by the filtered water when it is discharged through the drain pipe is effectively filtered on the outside of the filter cloth, thereby ensuring the filtering effect. However, after long-term use, the sand and gravel slowly gather on one side of the filter cloth, and the sand and gravel will slowly gather and gradually block one side of the filter cloth, thereby reducing the water flow rate. At this time, when cleaning, it is necessary to disassemble the drain pipe, take out the filter cloth in the drain pipe, and clean it, which is more troublesome. At the same time, after the filter cloth is taken out, the filtered sewage cannot be discharged further, and the filtering process needs to be stopped, thereby reducing the working efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The sewage enters the treatment cylinder 2 through the input pipe 3, and the sewage passes through the three-layer filter layer 5. The sand inside filters the sewage, making the sewage gradually clear, and the sewage flows out through the output pipe 4. At this time, one of the circular cylinders 10 is located between the output pipe 4 and the vertical pipe 7. The treated sewage flows down from the output pipe 4, passes through the filter cloth 11, enters the vertical pipe 7 and flows out. The filter cloth 11 filters out the sand and gravel particles in the treated sewage, and the sand and gravel stay on the surface of the filter cloth 11 to improve the filtering effect. After a long time, the motor 12 is turned on to drive the circular block 8 to rotate, and the circular cylinder that has been used for a long time is used. 10 is rotated and separated from between the vertical pipe 7 and the output pipe 4, and the circular cylinder 10 that is not in use or has been cleaned of sand and gravel is rotated between the vertical pipe 7 and the output pipe 4, so that the staff can clean the sand and gravel in the circular cylinder 10 that has been used for a long time, and avoid the accumulation of sand and gravel due to long-term use, which blocks the filter cloth 11, reduces the passing rate of the filter cloth 11, and blocks the sewage output. At the same time, when the used circular cylinder 10 is cleaned, the new circular cylinder 10 replaces the used circular cylinder 10. There is no need to stop the filtration process when cleaning the sand and gravel in the circular cylinder 10, which is conducive to improving work efficiency.

[0023] A first rubber tube 13 is fixedly connected to the transverse plate 6, and the first rubber tube 13 is fixedly connected to the vertical tube 7. A vertical rod 14 is fixedly connected to the transverse plate 6, and one side of the vertical rod 14 is fixedly connected to a support rod 15, and one end of the support rod 15 is fixedly connected to a second rubber tube 16, and the second rubber tube 16 is fixedly connected to the output tube 4. One side of the circular cylinder 10 is fixedly connected to a circular seat 17, and the circular seat 17 is rotatably connected to the round rod 9. A torsion spring is provided at the connection between the circular seat 17 and the round rod 9, and one side of the circular seat 17 is fixedly connected to an inclined toggle rod 18, and the lower end of the toggle rod 18 is provided with an arc surface. The lower surface of the transverse plate 6 is fixedly connected to an electric push rod 19, and the telescopic rod of the electric push rod 19 is fixedly connected to a push block 20, and the upper surface of the push block 20 is arc-shaped. The lower surface of the transverse plate 6 is fixedly connected to a collection frame 21.

[0024] When the circular cylinder 10 is located between the vertical pipe 7 and the output pipe 4, the first rubber tube 13 and the second rubber tube 16 are against the upper and lower surfaces of the circular cylinder 10, playing a certain sealing role to prevent sewage from spraying out through the gap between the circular cylinder 10 and the vertical pipe 7 and the output pipe 4. When the used circular cylinder 10 is horizontally rotated 180 degrees, the circular cylinder 10 is located above the pushing block 20. At this time, the electric push rod 19 pushes the pushing block 20 upward, and the pushing block 20 pushes the toggle rod 18 upward to rotate the circular cylinder 10. The opening above the circular cylinder 10 turns to tilt downward, and the sand and gravel gathered inside the circular cylinder 10 slides down under the action of gravity and falls into the collection frame 21 for collection. The circular cylinder 10 is automatically cleaned, which is more convenient.

[0025] The working principle and use process of the utility model are as follows: sewage enters the treatment cylinder 2 through the input pipe 3, and the sewage passes through the three-layer filter layer 5. The treated sewage flows down from the output pipe 4, passes through the filter cloth 11, enters the vertical pipe 7 and flows out. The filter cloth 11 filters out the sand and gravel particles in the treated sewage, and the sand and gravel remain on the surface of the filter cloth 11. After a long time, the motor 12 is turned on, driving the circular block 8 to rotate, and the circular cylinder 10 that has been used for a long time is rotated to be separated from the vertical pipe 7 and the output pipe 4, and the circular cylinder 10 that has not been used or cleaned of sand and gravel is rotated between the vertical pipe 7 and the output pipe 4. When the used circular cylinder 10 is rotated horizontally by 180 degrees, the circular cylinder 10 is located above the pushing block 20. At this time, the electric push rod 19 pushes the pushing block 20 upward, and the pushing block 20 pushes the toggle rod 18 upward, so that the circular cylinder 10 rotates, and the opening above the circular cylinder 10 turns to be inclined downward, and the sand and gravel gathered inside the circular cylinder 10 slides down under the action of gravity and the circular cylinder 10 falls into the collection frame 21.
