Description

Technical Field

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

[0002] A quicksand filtration device is an advanced water filtration equipment. Its working principle is that the upward flowing water makes the sand bed in a fluidized state. Sewage enters from the bottom, and after passing through the filtration of the sand bed, clear water flows out from the top. It has the characteristics of good filtration effect, continuous operation, high automation degree, small floor area, strong adaptability, etc. It is suitable for the treatment of various water qualities and water volumes, and can be applied to fields such as sewage treatment, industrial water treatment, and drinking water treatment.

[0003] Existing technologies such as the utility model with the publication number CN212854778U. The utility model discloses a quicksand filtration device, including a tank body. The left side of the top of the tank body is provided with a water inlet. A water inlet pipe penetrates through the inner cavity of the water inlet. The bottom of the water inlet pipe is fixedly connected with a diversion pipe. The bottom of the diversion pipe penetrates through and is connected with a radiation water distribution pipe. A gas device is installed at the bottom of the radiation water distribution pipe. A gas pipe penetrates through the inner cavity of the diversion pipe. A support rod penetrates through the inner cavity of the gas pipe. An overflow weir is installed at the top of the inner cavity of the tank body. A fine sand washer is installed at the bottom of the overflow weir. A medicine injection port is opened on the right side of the top of the water inlet pipe. A water outlet is opened on the top of the right wall of the tank body. A detergent perfusion chamber is installed on the right side of the outer wall of the overflow weir. A detergent injection port is opened on the outer wall of the detergent perfusion chamber. Support frames are installed on the two inner walls of the tank body. A detergent medicine inlet is opened in the middle of the right wall of the tank body. The fine sand washer includes a shell, solving the problem that the existing water filtration device can only be used for the water use of individual industries and cannot meet the water use needs of a large group. Therefore, we have introduced a quicksand filtration device to solve the problems of high water purification cost and complex biodegradation process of water purification.

[0004] In daily work, it is found that when the existing quicksand filtration device is in use, due to the upward flowing water making the sand bed in a fluidized state, sewage enters from the bottom, and after passing through the filtration of the sand bed, clear water flows out from the top. However, the clear water flowing out is likely to carry the sand filter material away. After long-term use, a large amount of sand-filtered water will be lost, resulting in the thinning of the sand bed and the weakening of the filtration ability. It is necessary to frequently replenish new filter materials, increasing the material procurement and labor input costs. As a result, when the existing quicksand filtration device is in use, the problem of sand filter material being lost with the clear water is likely to occur. Summary of the Utility Model

[0023] Specifically, the interception device 5 includes a frame 51 which is arranged above the drain outlet 3. An interception net 52 is fixedly connected to the inner wall of the frame 51. A connection component 56 is arranged between the frame 51 and the drain outlet 3. Two slide rails 53 are fixedly connected to the surface of the frame 51. A scraping member 54 is slidably connected to the surface of the slide rails 53. A control component 55 is arranged on the surface of the quicksand filtering body 1.

[0024] In this implementation scheme: when the water filtered by the quicksand filtering body 1 is discharged through the drain outlet 3, the interception net 52 can intercept the carried sand filter material, and the scraping member 54 can scrape away the sand filter material on the interception net 52, reducing the large losses caused by the loss of sand filter material.

[0025] Specifically, a positioning plate 57 is fixedly connected to one side surface of the two slide rails 53. When the scraping member 54 slides, the positioning plate 57 can play a positioning role.

[0026] Specifically, the scraping member 54 includes a scraping plate 541 which is arranged above the interception net 52. Two sliding seats 542 are fixedly connected to both sides of the scraping plate 541. The sliding seats 542 are slidably connected to the surface of the slide rails 53.

[0027] In this implementation scheme: when the scraping member 54 scrapes the material, the sliding seats 542 drive the scraping plate 541 to move on the slide rails 53, so that the scraping plate 541 scrapes away the sand filter material for easy cleaning.

[0028] Specifically, the control component 55 includes a motor 551 which is fixedly connected to the surface of the quicksand filtering body 1. A pull rope 552 is fixedly connected to the output end of the motor 551. The other end of the pull rope 552 is fixedly connected to the surface of the scraping plate 541. A guiding plate 553 is fixedly connected to the upper surface of the positioning plate 57. The pull rope 552 passes through the guiding plate 553.

[0029] In this implementation scheme: when the motor 551 rotates, it can wind up the pull rope 552. The pull rope 552 can drive the scraping plate 541 and the sliding seats 542 to move through the guiding plate 553, realizing the cleaning effect.

[0030] Specifically, a spring 554 is sleeved on the surface of the pull rope 552. Both ends of the spring 554 are respectively fixedly connected to the surface of the scraping plate 541 and the guiding plate 553.

[0034] Working principle: When in use, raw water is introduced into the quicksand filtration body 1 through the water inlet pipe 2. Subsequently, the quicksand filtration body 1 can filter the raw water through the sand filter media. The filtered water is located above the quicksand filtration body 1 and is discharged into the drain pipe 4 through the drain port 3. When the filtered water enters the drain port 3, the intercepting net 52 can filter the discharged water and intercept the sand filter media carried in the water, reducing the loss of sand filter media. When a large amount of sand filter media accumulates on the intercepting net 52, the motor 551 is turned on. When the motor 551 rotates, it can wind up the pulling rope 552. The pulling rope 552 can drive the scraping plate 541 and the sliding seat 542 to move on the sliding rail 53 through the guiding plate 553. The spring 554 deforms under force, pushing the sand filter media on the intercepting net 52 away and redepositing it in the quicksand filtration body 1. After cleaning, the motor 551 pays out the pulling rope 552, and the spring 554 releases its elastic force, driving the scraping plate 541 to reset, completing the use.
