Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to quartz sand filtration equipment which is easy to repair. Background Art

[0002] The quartz sand filter uses quartz sand filter media under a certain pressure to pass water with high turbidity through a filter layer of a certain thickness, thereby effectively removing suspended impurities and clarifying the water. It is mainly suitable for water treatment turbidity removal and pre-polar treatment of softened water. The turbidity of the outlet water can reach below three degrees. The quartz sand filter mainly removes impurities such as mud, suspended matter, colloids, and algae in the water, reducing mechanical damage and pollution to the reverse osmosis components.

[0003] Currently, quartz sand is included in water treatment equipment, but quartz sand is often at the forefront of the water treatment sequence. Therefore, when the water treatment equipment is blocked, it is often necessary to disassemble and repair it layer by layer in order to find the blockage point. However, because of this, the approximate location of the blockage point cannot be determined before maintenance, which prolongs the maintenance time. For this reason, we provide a quartz sand filtration equipment that is easy to maintain to solve the above problems. Utility Model Content

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.

[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a quartz sand filtering device that is conducive to maintenance, comprising an outer shell 1, an observation window 2 is fixedly connected to the inner side of the outer shell 1, the top and bottom ends of the outer shell 1 are connected to a box cover 3 by a lock, a square plate 4 is fixedly connected to the inner surface of the outer shell 1, the outer surface of the square plate 4 and the curvature of the inner surface of the box cover 3 are consistent with each other, the outer surface of the square plate 4 is fixedly connected to an inner shell 5, and the inner wall of the inner shell 5 is fixedly connected to a partition plate 6, the box cover 3 can be fixed to the upper and lower ends of the outer shell 1 by the existing external lock, so as to form a relatively sealed environment with the outer shell 1, the square plate 4 can form a separate area between the outer shell 1 and the inner shell 5, the separate area can be observed through the observation window 2, so that the approximate blockage point can be judged in advance before maintenance, and the partition plate 6 can play an isolating role, which can isolate the quartz sand from the subsequent water treatment components, thereby facilitating the judgment before maintenance, thereby solving the problem that the approximate position of the blockage point cannot be determined before maintenance, thereby prolonging the maintenance time.

[0024] The inner wall of the inner shell 5 is slidably connected with filter plate 1 7, filter plate 2 8, filter plate 3 9 and filter plate 4 10. The bottom surface of filter plate 4 10 is in close contact with the outer surface of the partition plate 6. Filter plate 1 7, filter plate 2 8, filter plate 3 9 and filter plate 4 10 are connected as a whole through a hollow rod 11. The hollow rod 11 can connect filter plate 1 7, filter plate 2 8, filter plate 3 9 and filter plate 4 10 as a whole. The cavity between filter plate 1 7, filter plate 2 8, filter plate 3 9 and filter plate 4 10 is filled with quartz sand. At the same time, the body has good water permeability, so that the service life of quartz sand between filter plate 1 7 and filter plate 2 8 is extended without affecting the efficiency of the overall water treatment at the expense of the service life of quartz sand between filter plate 1 7 and filter plate 2 8. At the same time, the replacement amount of quartz sand can be reduced each time it is replaced.

[0025] The inner surface of the square plate 4 is fixedly connected with a branch plate 12 and a baffle plate 13, and the branch plate 12 and the baffle plate 13 are fixedly connected to the outer surface of the inner shell 5. The inner side of the inner shell 5 located between the branch plate 12 and the baffle plate 13 is provided with a water port 14, and a wire mesh is installed inside the water port 14, which can intercept quartz sand. The water flow inside the inner shell 5 can enter the separate area formed by the square plate 4, the inner shell 5 and the outer shell 1 through the water port 14, and the baffle plate 13 can separate the water volume of the two water ports 14. At the same time, the branch plate 12 can make the water flow form a U-shaped flow, which is convenient for observing the water flow outside the equipment, and the blockage position can be judged by comparing the water flow.

[0026] A detection plate 15 is fixedly connected to the outer surface of the partition plate 6, a detection hole 16 is opened on the inner side of the detection plate 15, and a support frame 17 is fixedly connected to the inner wall of the detection hole 16. The partition plate 6 is made of a waterproof material, and a one-way valve is installed inside the water port 14 between the detection plate 15 and the partition plate 6 to allow water to maintain one-way flow.

[0027] The bottom surface of the support frame 17 is rotatably connected with a propeller 18. When water flows through the detection hole 16, it can push the propeller 18, thereby causing the propeller 18 to rotate. The outer surface of the propeller 18 is fixedly connected with an output end 19, and the output end 19 is fixedly connected with a cross bar 20. The outer surface of the cross bar 20 is fixedly connected with a circular frame 21. When the propeller 18 rotates, it can drive the output end 19 and the cross bar 20 to rotate. The cross bar 20 is made of solid stainless steel as a whole, so that it has a certain inertia, which reduces the rotation amplitude of the propeller 18 when the water flow impacts the cross bar 20. The outer surface of the circular frame 21 is provided with metal teeth 22. The output end 19 can drive the circular frame 21 and the metal teeth 22 through the cross bar 20. The material of the circular frame 21 is the same as that of the metal teeth 22.

[0028] A mounting bracket 23 is fixedly connected to the bottom surface of the detection plate 15, and a frequency measurement sensor 24 is fixedly connected to the outer surface of the mounting bracket 23. The horizontal height of the sensing end of the frequency measurement sensor 24 is flush with the horizontal height of the metal teeth 22. The mounting bracket 23 can provide installation and load-bearing functions for the frequency measurement sensor 24. The frequency measurement sensor 24 can derive the rotational speed of the propeller 18 based on the amplitude of the tooth movement.

[0029] Working principle: When the device is needed, first use a booster pump to inject the water to be treated into the inner shell 5 through the water injection port set in the box cover 3, and the water will pass through the quartz sand between the filter plate 1 7, the filter plate 2 8, the filter plate 3 9 and the filter plate 4 10 in turn. At the same time, each cavity between the filter plate 1 7, the filter plate 2 8, the filter plate 3 9 and the filter plate 4 10 will correspond to two water ports 14. Part of the water will first pass through the water ports 14 into the separate area formed between the square plate 4, the inner shell 5 and the outer shell 1, so that the water quality and water flow can be observed from the outside, and then it will Bypassing the partition plate 6 and passing through the detection hole 16, when water flows into the detection hole 16, it will push the propeller 18 to rotate, and the propeller 18 can drive the metal teeth 22 to rotate. The frequency measurement sensor 24 can calculate the rotation speed of the propeller 18 according to the moving speed of the metal teeth 22. When the rotation speed is lower than the set range, it means that the upper layer of quartz sand is blocked, and then a warning command will be issued to the central control console, so that the on-duty personnel can be notified to go to the site to check the equipment, so that the on-duty personnel can observe the specific blockage location through the observation window 2 as soon as the blockage occurs.
