Description

Technical Field

[0001] This invention belongs to the technical field of water treatment equipment, specifically relating to a multi-layer quartz sand filter structure. Background Technology

[0002] Water treatment, as a core component in ensuring water resource security and promoting water conservation and emission reduction, has become a fundamental industry supporting economic and social development and people's livelihood. It is widely used in municipal water supply, industrial wastewater treatment, reclaimed water reuse, and groundwater purification. Currently, source water quality exhibits complexity and volatility. Raw water not only contains a large amount of conventional impurities such as suspended solids and colloidal particles, but also thousands of trace pollutants. Some water sources even experience extreme situations such as a sudden increase in turbidity and an explosive growth of algae, posing significant challenges to water treatment processes. Quartz sand filters, as the core pressure filtration device in water treatment systems for achieving solid-liquid separation and reducing water turbidity, are widely used in various water treatment scenarios due to their simple structure, moderate cost, and stable treatment effect.

[0003] Most existing quartz sand filters use a single layer of filter media for filtration, resulting in poor filtration performance. They cannot perform deep filtration of wastewater and cannot guarantee the treatment effect of wastewater. Summary of the Invention

[0004] This invention provides a multi-layer quartz sand filter structure, which aims to solve the problem that most existing quartz sand filter structures use a single layer of filter media for filtration, resulting in poor filtration effect, inability to perform deep filtration of sewage, and inability to guarantee the treatment effect of sewage.

[0005] This invention provides a multi-layer quartz sand filter structure, including a drain port and a liquid inlet. The upper end of the drain port is fixedly connected to a filter cylinder, and the lower end of the liquid inlet is fixedly connected to a shell. The shell is clamped to the outside of the filter cylinder. A first filter plate is fixedly connected at the connection between the drain port and the filter cylinder, and a second filter plate is fixedly connected at the connection between the liquid inlet and the shell. An activated carbon deodorizing layer and several quartz sand filter layers are sequentially arranged from bottom to top in the space formed by the filter cylinder, the first filter plate, and the second filter plate. A coaxial receiving cavity is reserved on the outer ring surface of the outer shell. An assembly cavity is reserved on one side of the receiving cavity, and a pressing cavity is reserved on the other side of the receiving cavity. A flipping block fixed to the outer shell is installed in the pressing cavity. A disassembly table is installed in the cavity formed by the receiving cavity, the assembly cavity and the pressing cavity. The side wall of one end of the disassembly table is connected to the outer shell through the flipping block, so that the disassembly table can rotate around the center of the flipping block. The disassembly table is equipped with a pressing end, a restraining end, and a stopping end in sequence along its central axis. The pressing end is partially located in the pressing cavity, the restraining end is located in the receiving cavity, and the restraining end has a notch reserved on it for assembling the restraining table installed on the outer ring wall of the filter cartridge. The stopping end is located in the assembly cavity, and the stopping end and the restraining table are in contact with each other. It also includes an outer cylinder that is clamped to the outer shell. A constraint opening is reserved on the outer cylinder. A spring steel sheet is installed on one side of the constraint opening. The spring steel sheet is fixed to the outer cylinder on one side. A constraint block is installed on the other side of the spring steel sheet. The constraint block is located in the assembly cavity. The skewed wall on the constraint block presses against the stop end. This filter structure includes a fastened configuration, an initial disassembly configuration, and a fully disassembled configuration; When this filter structure is in the fastened state, the constraint platform is in the notch, the stop end is in the assembly cavity, and the skewed wall on the constraint block presses against the stop end. When disassembling this filter structure for the first time, pull the outer cylinder upwards until the outer cylinder presses against the protrusion. At this point, the constraint block is removed from the assembly cavity and is on the constraint platform. When the entire filter structure is disassembled, pressure is applied to the pressing end, causing the disassembly platform to rotate around the flipping block under external force, separating the stop end and the constraint platform, thereby achieving the purpose of disassembling the filter cartridge and the outer shell, which in turn facilitates the cleaning or replacement of the filter media in the filter cartridge.

[0006] Furthermore, several sealing rings are fixed to the top of the filter cylinder, and the radii of the sealing rings decrease sequentially from the outside to the inside. When the outer shell is fastened to the filter cylinder, the sealing rings are pressed between the filter cylinder and the filter plate.

[0007] Furthermore, the activated carbon deodorizing layer and the adjacent quartz sand filter layer are separated by a water-permeable isolation net, and the particle size of the several quartz sand filter layers increases sequentially from bottom to top.

[0008] Furthermore, one side of the constraint block is a skewed wall, and when the outer cylinder moves toward the pressing end, the skewed wall comes into contact with the stop end.

[0009] Furthermore, arrows are installed on the outer cylinder and on the side of the constraint opening for pointing during assembly.

[0010] Furthermore, several grooves are reserved on the outer ring wall of the outer cylinder.

[0011] Furthermore, a barrier ring is fixed to the outer ring wall on the other side of the outer shell, and the side wall of the barrier ring is sloping; a U-shaped opening matching the barrier ring is reserved on the side of the outer cylinder that is farther from the guide port.

[0012] Furthermore, several patterns are reserved on the outer side of the compression end.

[0013] Furthermore, a transverse wall is reserved on the outer ring wall of the filter cylinder. The transverse wall is positioned opposite the filter cylinder and is located on the side of the transverse part that is farther from the vertical part. When it is in a tightened state, the restraint block presses against the transverse wall.

[0014] The beneficial effects of this invention are as follows: 1. In this invention, an activated carbon deodorizing layer and several quartz sand filter layers are sequentially installed from bottom to top in the space formed by the filter cylinder, filter plate one, and filter plate two. The particle size of the several quartz sand filter layers increases sequentially from bottom to top. Wastewater enters the filter cylinder from the inlet and passes through multiple layers of filter media to intercept impurities in the wastewater. The upper filter media intercepts large particles of impurities, while the lower filter media intercepts fine particles of impurities. The filtered water is discharged from the outlet, achieving multi-level and deep filtration, significantly improving the interception capacity and filtration accuracy, and making the filtered water quality more stable.

[0015] 2. The invention has a clever structure and appropriate distribution. The outer cylinder is constrained after the filter cylinder and the outer shell are fastened to prevent the filter cylinder and the outer shell from separating under external conditions, thus ensuring the stability of the fastening. This structure can also protect the disassembly table to prevent it from undergoing changes in shape, so that it can work for a longer time. When the outer shell and filter cartridge are in a fastened state, the constraint platform is in the notch, and the inner surfaces of the constraint platform and the constraint end are in contact, constraining the filter cartridge to rotate circumferentially. The outer surface of the constraint platform and the inner surface of the stop end are in contact, constraining the movement of the filter cartridge in the length direction. When disassembling the outer shell and filter cartridge, the pressure end is pressed, and the disassembly platform is rotated under external force, allowing the stop end and the constraint platform to separate, and the filter cartridge and outer shell to disassemble. It is very convenient and stable to use, and then it is easy to clean the inside of the device.

[0016] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-7This invention proposes a multi-layer quartz sand filter structure, comprising a drain port 1 and an inlet port 2. The upper end of the drain port 1 is fixedly connected to a filter cylinder 3, and the lower end of the inlet port 2 is fixedly connected to a housing 4. The housing 4 is clamped to the outside of the filter cylinder 3. A filter plate 6 is fixedly connected at the connection between the drain port 1 and the filter cylinder 3, and a filter plate 7 is fixedly connected at the connection between the inlet port 2 and the housing 4. Several sealing rings 8 are fixedly connected to the top of the filter cylinder 3, with the radius of the sealing rings 8 decreasing sequentially from the outside to the inside. When the housing 4 and the filter cylinder 3 are tightened, the sealing rings 8 are pressed between the filter cylinder 3 and the filter plate 7, ensuring the sealing performance after the filter cylinder 3 and the housing 4 are tightened, thereby ensuring sufficient filtration of wastewater. The filter cylinder 3, filter plate 6, and filter plate... In the space consisting of two layers 7, an activated carbon deodorizing layer 9 and several quartz sand filter layers 10 are arranged sequentially from bottom to top. The activated carbon deodorizing layer 9 and its adjacent quartz sand filter layers 10, as well as the adjacent quartz sand filter layers 10, are separated by a water-permeable isolation net to prevent the mixing of filter media and to fully utilize the interception function of each layer of filter media. The particle size of the several quartz sand filter layers 10 increases sequentially from bottom to top. Wastewater enters the filter cylinder 3 from the inlet 2 and passes through multiple layers of filter media to intercept impurities in the wastewater. The upper filter media intercepts large particles of impurities, while the lower filter media intercepts fine particles of impurities. The filtered water is discharged from the outlet 1, achieving multi-level and deep filtration, greatly improving the interception capacity and filtration accuracy, and making the filtered water quality more stable. A coaxial receiving cavity 41 is reserved on the outer ring surface of the outer shell 4. An assembly cavity 42 is reserved on one side of the receiving cavity 41, and a pressing cavity 43 is reserved on the other side of the receiving cavity 41. The receiving cavity 41, assembly cavity 42, and pressing cavity 43 are all square, and the span of the assembly cavity 42 and the pressing cavity 43 is greater than the span of the receiving cavity 41. A flipping block 44 fixed to the outer shell 4 is installed in the pressing cavity 43. The flipping block 44 is made of spring steel. A disassembly table 45 is installed in the cavity formed by the receiving cavity 41, assembly cavity 42, and pressing cavity 43. One side wall of the disassembly table 45 is connected to the outer shell 4 via the flipping block 44, so that the disassembly table 45 can rotate around the center of the flipping block 44.

[0020] Along its central axis, the disassembly table 45 is sequentially equipped with a pressing end 451, a restraining end 452, and a stopping end 453. The pressing end 451 is partially located in the pressing cavity 43, the restraining end 452 is located in the receiving cavity 41, and the restraining end 452 has a notch 454 reserved on it for assembling the restraining table 31 installed on the outer ring wall of the filter cylinder 3. The stopping end 453 is located in the assembly cavity 42, and the stopping end 453 and the restraining table 31 are in contact with each other.

[0021] When the outer shell 4 and the filter cartridge 3 are in a fastened state, the restraint platform 31 is in the notch 454, and both sides of the restraint platform 31 contact the inner surface of the restraint end 452, restricting the circumferential rotation of the filter cartridge 3. The outer side of the restraint platform 31 abuts against the inner wall of the stop end 453, restricting the movement of the filter cartridge 3 in the axial direction. When disassembling the outer shell 4 and the filter cartridge 3, the pressing end 451 is squeezed, and the disassembly platform 45 is flipped under an external force, causing the stop end 453 to move away from the restraint platform 31, so that the filter cartridge 3 and the outer shell 4 can be disassembled.

[0022] A number of纹路455 are reserved on the outer side of the pressing end 451. The arrangement of the纹路455 can enhance the blocking effect at the pressing end 451, prevent the occurrence of slipping, and facilitate operation.

[0023] The restraint platform 31 is in a "丄" - shaped structure. The restraint platform 31 includes a horizontal portion 311 and a vertical portion 312. The included angle between the horizontal portion 311 and the vertical portion 312 is 90 degrees. The vertical portion 312 and the filter cartridge 3 are arranged opposite to each other. The vertical portion 312 is in a wedge - shaped structure. The vertical wall surface of the vertical portion 312 is attached to and integrated with the horizontal portion 311. The slope surface of the vertical portion 312 can assist during disassembly or fastening, preventing the disassembly platform 45 from malfunctioning due to a strong change in the shape of the restraint end 452, and ensuring long - term use.

[0024] It further includes an outer cylinder 5 sleeved on the outer shell 4. A restraint opening 51 is reserved on the outer cylinder 5. A spring steel sheet 52 is arranged on one side of the restraint opening 51. One side of the spring steel sheet 52 is fixedly connected to the outer cylinder 5. A restraint block 53 is arranged on the other side of the spring steel sheet 52. One side of the restraint block 53 is an inclined wall 531. When the outer cylinder 5 moves towards the pressing end 451, the inclined wall 531 contacts the stop end 453. The restraint block 53 is in the assembly cavity 42, and the inclined wall 531 on the restraint block 53 presses on the stop end 453. The overall structure is ingenious and the structure is appropriate. The outer cylinder 5 performs restraint after the filter cartridge 3 and the outer shell 4 are fastened, preventing the filter cartridge 3 and the outer shell 4 from separating under an external force and ensuring the fastening stability.

[0025] An embedding interface 47 is reserved on the outer ring wall on one side of the outer shell 4. An embedding strip 471 arranged opposite to the outer shell 4 is arranged in the embedding interface 47. One side of the embedding strip 471 is fixedly connected to the outer shell 4, and a boss 472 is fixedly connected to the other side of the embedding strip 471. A guiding opening 56 matching the boss 472 is arranged on one side of the outer cylinder 5 close to the boss 472. The boss 472 can restrain the outer cylinder 5, preventing the outer cylinder 5 from loosening from the outer shell 4 and facilitating reuse.

[0026] A barrier ring 46 is fixed to the outer circumferential wall of the outer shell 4. The side wall of the barrier ring 46 is sloped. A U-shaped opening 55 matching the barrier ring 46 is reserved on the side of the outer cylinder 5 that is farther from the guide port 56. The matching of the barrier ring 46 and the U-shaped opening 55 can constrain the circumferential rotation of the outer cylinder 5 and can guide the assembly of the outer cylinder 5, which is convenient for assembly.

[0027] Arrow 50 is installed on the outer cylinder 5, near the restraint opening 51, for directional guidance during assembly and ease of use. Several grooves 54 are pre-drilled on the outer ring wall of the outer cylinder 5; these grooves reduce the weight of the device and lower manufacturing costs. A transverse wall 32 is pre-drilled on the outer ring wall of the filter cylinder 3, directly opposite the filter cylinder 3, located on the side of the transverse portion 311 furthest from the vertical portion 312. When tightened, the restraint block 53 presses against the transverse wall 32.

[0028] Reference Figures 5-7 This filter structure includes a fastened configuration, an initial disassembly configuration, and a fully disassembled configuration.

[0029] Reference Figure 5 When the filter structure is in the tightened state, the constraint platform 31 is in the notch 454, the stop end 453 is in the assembly cavity 42, and the skewed wall 531 on the constraint block 53 presses against the stop end 453.

[0030] Reference Figure 6 When the filter structure is disassembled for the first time, the outer cylinder 5 is pulled upward until it presses against the protrusion 472. At this moment, the constraint block 53 is removed from the assembly cavity 42 and is on the constraint table 31.

[0031] Reference Figure 7 When the filter structure is completely disassembled, pressure is applied to the pressing end 451, causing the disassembly table 45 to rotate around the flipping block 44 under external force, separating the stop end 453 from the constraint table 31, thereby achieving the purpose of disassembling the filter cartridge 3 from the outer shell 4, which facilitates the cleaning or replacement of the filter media in the filter cartridge 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
