Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a water treatment sand cleaning device. Background Art

[0002] The sand filter uses quartz sand as filter material. The quartz sand filter material is polygonal, spherical, pure white in appearance, and has the characteristics of high mechanical strength, strong pollution interception ability, and good acid resistance. During the filtration process, impurities in the water will be wrapped on the surface of the quartz sand to form a compaction, resulting in a decrease in filtration efficiency. In order to extend the service life of the quartz sand, it is necessary to manually turn over and break the quartz sand in the sand filter regularly, which is time-consuming and labor-intensive, difficult to handle, and inefficient. Moreover, after treatment, the impurities attached to the surface of the quartz sand are still in the sand filter. After multiple treatments, the quartz sand in the sand filter will no longer meet the filtration requirements, and its service life is short, resulting in waste. Utility Model Content

[0014] Embodiment 1:

[0015] like Figure 1-Figure 3As shown, the utility model discloses a water treatment sand cleaning device, comprising a sand filter 15 and a sand storage tank 1. A vacuum generator 2 is provided on the upper side of the sand storage tank 1. A sand suction pipe 3 is provided on the vacuum generator 2. One end of the sand suction pipe 3 extends to the inside of the sand filter 15, and the other end is connected to the sand storage tank 1. The vacuum generator 2 creates a pressure difference in the sand suction pipe 3 to suck sand from the sand filter 15 into the sand storage tank 1. A sand feeder 5 is provided on the bottom side of the sand storage tank 1. The quartz sand in the sand storage tank 1 enters the sand feeder 5 due to gravity. The sand feeder 5 regularly transports the quartz sand to the material port 10 of the sand regeneration drum body 4. A sand regeneration drum is provided on the lower side of the sand feeder 5. The raw material drum includes a base 6, on which a drum body 4 is rotatably provided. The drum body 4 can be placed horizontally to make the friction between the quartz sands in the drum body 4 more sufficient. However, in actual use, in order to prevent the quartz sands in the drum body 4 from falling, the drum body 4 maintains a certain inclination angle with the horizontal plane. A material port 10 is provided at one end of the drum body 4 that is inclined upward for feeding and discharging materials. A motor 8 is axially provided at one end of the drum body 4 that is inclined downward, and the motor 8 can drive the drum body 4 to rotate. A stirring blade 17 is provided on the inner wall of the drum body 4, and the stirring blade 17 is spirally extended from one end of the drum body 4 to the other end. The motor 8 drives the drum body 4 to rotate forward, and the stirring blade 17 drives the quartz sand to the inside of the drum body 4, and the quartz sand rolls and rubs in the drum body 4 to achieve The effect of separating the quartz sand and the impurities attached to the quartz sand is achieved; the motor 8 drives the drum body 4 to reverse, and the stirring blades 17 push the quartz sand and the separated impurities out from the material port 10 and enter the material inlet 20 of the sediment separator 9; the sediment separator 9 is provided below the upwardly inclined end of the drum body 4, and the upper side of the sediment separator 9 is provided with a material inlet 20, and the sediment separator 9 is provided with an inclined screen plate 11 inside, and the inclined screen plate 11 is inclined to one side. Because the particle size of the quartz sand is larger than the particle size of the impurities, the impurities pass through the inclined screen plate 11 and fall into the lower side of the inclined screen plate 11, and the quartz sand remains on the upper side of the inclined screen plate 11. The inclined screen plate 11 accelerates the screening of impurities through vibration, and at the same time accelerates the accumulation of quartz sand at the low position of the inclined screen plate 11. A sand return pipe 12 is provided on the side wall of the sediment separator 9 above the downwardly inclined end of the inclined screen plate 11, and the sand return pipe 12 extends to the sand filter 15. The quartz sand cleaned of impurities returns to the sand filter 15 through the sand return pipe 12. A mud discharge pipe 13 is provided on the bottom side of the sediment separator 9, and the separated impurities are discharged from the sediment separator 9 for treatment through the mud discharge pipe 13; a guide rail 16 is provided on the upper side of the sand filter 15, and a pipe tractor 14 is slidably provided on the guide rail 16, and the pipe tractor 14 is connected to the sand suction pipe 3 and the sand return pipe 12, and the pipe tractor 14 drives the sand suction pipe 3 and the sand return pipe 12 to move regularly on the guide rail 16 to ensure that the quartz sand in the sand filter 15 can be cleaned.

[0016] The pipe tractor 14 can move autonomously on the guide rail 16, and its specific structure is not described in detail. The vacuum generator 2 can be a pump body.

[0018] The material inlet 10 of the drum body 4 is provided with a blocking net 18, the aperture of the blocking net 18 is smaller than the outer diameter of the sand regeneration ball 19, to prevent the mixing blade 17 from pushing the sand regeneration ball 19 out of the drum body 4 when the motor 8 reverses.

[0019] The end of the sand suction pipe 3 is a hard plastic pipe, and the rest is a hose. The plastic pipe is used to ensure that the end of the sand suction pipe 3 can be inserted into the quartz sand in the sand filter 15, thereby increasing the sand suction efficiency.

[0020] The mixture of quartz sand and impurities pushed out of the material port 10 of the drum body 4 cannot accurately fall into the sediment separator 9, thereby causing the loss of quartz sand, so a chute 7 is provided on the base 6 under the material port 10 of the drum body 4, and the chute 7 is inclined to one end, and the upper end of the chute 7 is located below the material port 10 of the drum body 4, and the lower end of the chute 7 is located above the feed port 20 of the sediment separator 9, and the chute 7 guides the mixture of quartz sand and impurities pushed out of the material port 10 of the drum body 4 to the sediment separator 9.
