Description

Technical Field

[0001] The present application relates to the field of pure water treatment, and in particular to a sand filtration mechanism and pure water treatment equipment. Background Art

[0002] Our pure water equipment utilizes the world's most advanced reverse osmosis membrane elements, pressure vessels, and high-pressure pumps, along with efficient pre-treatment equipment and post-treatment fine desalination equipment. Sand filtration is a water filtration process using natural quartz sand, often accompanied by manganese sand and anthracite, as the filter media. The quartz sand typically has a particle size of 0.5-1.2mm and a coefficient of nonuniformity of 2. The filter layer thickness and filtration rate are determined by the quality of the source and effluent water. Sand filtration can be divided into gravity and pressure types and is commonly used for treating feedwater after clarification (sedimentation) or for advanced treatment of wastewater after secondary treatment and for wastewater reuse.

[0003] During the sand filtration process, pure water is passed into the sand filtration device, filtered through the filter material in the sand filtration device, and the pure water flows upward in the sand filtration device for filtration. The filtered pure water is discharged to the next process through the drain pipe at the top of the sand filtration device. However, when the pure water flows upward in the sand filtration device, some sand particles will be entrained and flow along with the water flow, causing a small amount of sand particles to be suspended on the top of the sand filtration device. As a result, sand particles will follow the water flow into the drain pipe, causing sand loss. For this reason, we have proposed a sand filtration mechanism and pure water treatment equipment. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a sand filtration mechanism and pure water treatment equipment, aiming to improve the problem of easy loss of sand particles in existing sand filtration devices.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0022] See also Figure 1-4 The present application provides a sand filter mechanism, including a sand filter device 10. The side wall of the sand filter device 10 is connected to a drainage pipe 20, and the drainage pipe 20 is L-shaped. A water wheel drive mechanism 30 is rotatably passed through the side wall of the drainage pipe 20, and a filter screen 40 is installed in the inlet end thereof. A cleaning mechanism 50 is rotatably passed through the side wall of the sand filter device 10, and the cleaning mechanism 50 is driven by the water wheel drive mechanism 30. Specifically, raw water is passed into the sand filter device 10 for filtration, and the filtered water flows upward and enters the drainage pipe 20 and is discharged to the next process. , and the water flows upward in the sand filter device 10, which will drive a small amount of sand to move and make the sand suspended on the top of the sand filter device 10. Therefore, by installing a filter screen 40 in the inlet end of the drainage pipe 20, it is possible to prevent the sand from flowing. Since there is a negative pressure at the inlet end of the drainage pipe 20, the sand will be adsorbed on the filter screen 40. A water wheel driving mechanism 30 is installed in the drainage pipe 20. The water wheel driving mechanism 30 drives the cleaning mechanism 50 to rotate, so that the cleaning mechanism 50 can clean the sand adsorbed on the filter screen 40 to avoid affecting the water flow.

[0023] See Figure 4 The water wheel driving mechanism 30 includes a rotating shaft 310 that is arranged to rotate and pass through the side wall of the drainage pipe 20. A driving water wheel 320 located in the drainage pipe 20 is installed at one end of the rotating shaft 310. It also includes a transmission mechanism 330 that is rotatably connected to the outer wall of the drainage pipe 20. The rotating shaft 310 and the transmission mechanism 330 are transmitted. When the water flows through the driving water wheel 320, it will cause the driving water wheel 320 to rotate, thereby driving the water wheel 320 to drive the rotating shaft 310 to rotate, and the rotating shaft 310 drives the transmission mechanism 330 to rotate.

[0024] See Figure 3The transmission mechanism 330 includes a transmission rod 3310 rotatably connected to the outer wall of the drainage pipe 20, and a first ring gear 3320 is installed on the transmission rod 3310. The first ring gear 3320 transmits power to the rotating shaft 310, and the transmission rod 3310 transmits power to the cleaning mechanism 50. A second ring gear 340 is installed on the rotating shaft 310, and the second ring gear 340 transmits power to the first ring gear 3320. In the specific setting, the rotating shaft 310 drives the second ring gear 340 to rotate, the second ring gear 340 drives the first ring gear 3320 to rotate, and the first ring gear 3320 drives the transmission rod 3310 to rotate, so that the transmission rod 3310 drives the cleaning mechanism 50 to rotate.

[0025] See Figure 3 and 4 The cleaning mechanism 50 includes a rotating rod 510 that rotates and penetrates the side wall of the sand filter device 10. The rotating rod 510 is driven by the transmission rod 3310, and a cleaning plate 520 is fixedly installed at one end thereof. A brush is provided on the side wall of one end of the cleaning plate 520. Specifically, the transmission rod 3310 drives the rotating rod 510 to rotate, so that the rotating rod 510 drives the cleaning plate 520 to rotate, so that the brush intermittently contacts the filter screen 40 to clean the sand on the filter screen 40, thereby preventing water from entering the drainage pipe 20.

[0026] See Figure 3 A first pulley 3330 is installed on the transmission rod 3310, and a second pulley 530 is installed on the rotating rod 510. The same transmission belt 60 is wound around the first pulley 3330 and the second pulley 530. In the specific setting, the transmission rod 3310 drives the first pulley 3330 to rotate, and the first pulley 3330 drives the second pulley 530 to rotate through the transmission belt 60, so that the second pulley 530 drives the rotating rod 510 to rotate.

[0028] The sand filter mechanism mentioned above.

[0029] When the sand filter mechanism and the pure water treatment equipment are in operation: the raw pure water is put into the sand filter device 10, and after being filtered by the sand filter device 10, it flows upward, so that the filtered pure water enters the drainage pipe 20. When the water flows in the drainage pipe 20, it drives the driving water wheel 320 to rotate, thereby driving the water wheel 320 to drive the rotating shaft 310 to rotate, and the rotating shaft 310 drives the second ring gear 340 to rotate, so that the second ring gear 340 drives the first ring gear 3320 to rotate, so that the first ring gear 3320 drives the transmission rod 3310 to rotate, and the transmission rod 3310 then drives the first pulley 3330 to rotate, so that the first pulley 3330 drives the second pulley 530 to rotate through the transmission belt 60, so that the second pulley 530 drives the rotating rod 510 to rotate, so that the rotating rod 510 drives the cleaning plate 520 to rotate, so that the sand particles on the filter screen 40 are cleaned by the brush on the cleaning plate 520 to avoid affecting the flow of water.

[0030] It should be noted that the specific models and specifications of the sand filter device 10 and the driving water wheel 320 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
