Description

Technical Field

[0001] This utility model belongs to the technical field of multi-media filtration devices, and in particular relates to a multi-media filtration device for sewage treatment. Background Technology

[0002] Multi-media filtration devices for wastewater treatment are highly efficient purification equipment that combines multiple layers of different media. They are widely used in the treatment of industrial wastewater, municipal water supply, and domestic sewage. Their core principle is to remove suspended solids, colloids, organic matter, heavy metals, and other pollutants from water through physical interception, adsorption, and oxidation.

[0003] For example, CN219376386U discloses a multi-media filtration device for wastewater treatment, which includes a filter box. A partition is vertically arranged along the middle of the filter box, dividing it into a pushing chamber and a filtering chamber. A flushing pipe penetrating the filter box is located at the top of the filter box corresponding to the filtering chamber. A filter bed is located at the bottom of the filtering chamber. A water outlet pipe is connected through the side of the filtering chamber. A sewage discharge pipe is connected through the bottom of the filter box. A push rod mechanism is located at the top of the filter box corresponding to the pushing chamber. A water inlet pipe is connected through the side of the pushing chamber. The push rod penetrates the filter box, and a push plate is located at the lower end of the push rod. The beneficial effects are: the push rod mechanism is located at the top of the pushing chamber, the filter bed is located at the bottom of the filtering chamber, and the water outlet pipe is connected through the side of the filtering chamber. Wastewater enters the filter box through the water inlet pipe, passes through the filter bed, and is discharged through the water outlet pipe. Impurities do not accumulate on the filter bed but are deposited at the bottom of the filter box, improving filtration efficiency.

[0004] The above-mentioned patent has the following defects in use:

[0005] The flushing pipe flushes from top to bottom. During the cleaning process, the filter media in the three layers of filter media inside the filter bed are cleaned more thoroughly, while the filter media farther away from the flushing pipe are not cleaned thoroughly enough and are prone to residue, which affects the subsequent use of the filter media. Therefore, this utility model proposes a multi-media filtration device for sewage treatment. Utility Model Content

[0006] This utility model provides a multi-media filtration device for sewage treatment. A flushing and brushing mechanism sprays water from below to flush the anthracite layer, simultaneously driving a cleaning brush to scrub the top anthracite layer, compensating for insufficient flushing at the top and making the cleaning more thorough and comprehensive. A vibration-assisted mechanism uses impact vibration to loosen impurities clogging the micropores in the anthracite, quartz sand, and garnet layers, allowing them to be flushed away by water or the brush, further enhancing the cleaning and reducing residue. In summary, this invention solves the problems in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a multi-media filtration device for wastewater treatment, comprising:

[0009] A filter box, wherein a water inlet pipe is fixedly connected to one side of the filter box, and the interior of the filter box is arranged from top to bottom as anthracite layer, quartz sand layer and garnet layer;

[0010] A flushing and brushing mechanism is installed on the filter box and is used for cleaning the anthracite coal seam, quartz sand layer and garnet layer.

[0011] A vibration auxiliary mechanism is provided on the outside of the filter box and is used to assist in the cleaning of the anthracite coal seam, quartz sand layer and garnet layer.

[0012] The flushing and brushing mechanism includes a water guide pipe embedded in and connected to one side of the filter box. Multiple flushing nozzles are fixedly connected to the outer wall of the water guide pipe. An L-shaped plate is fixedly connected to the top of the filter box, and a motor is fixedly connected to the inner top of the L-shaped plate.

A pair of cleaning brushes are fixedly connected to the outer wall of the rotating rod, and the bottom ends of the pair of cleaning brushes are in contact with the top of the anthracite coal seam.

[0013] Furthermore, a filter screen is fixedly connected to the inner wall of the water inlet pipe, and the filter screen is located at the top of the anthracite coal seam.

[0014] Furthermore, a T-shaped sealing block is fixedly connected to one side of each of the anthracite coal layer, quartz sand layer, and garnet layer. Three through-holes are drilled on the side of the filter box near the T-shaped sealing block, and the outer wall of the T-shaped sealing block is in close contact with the inner wall of the through-hole. All three T-shaped sealing blocks are connected to the filter box by bolts.

[0015] Furthermore, the inner wall of the filter box is chiseled with three pairs of guide grooves, and each pair of guide grooves is provided with a guide block in contact with it. The opposite sides of the three pairs of guide blocks are fixedly connected to the outer walls of the anthracite layer, the quartz sand layer and the garnet layer, respectively.

[0016] Furthermore, the vibration assist mechanism includes a cam sleeved on the outer wall of the rotating rod, an arc-shaped block slidably connected to the top of the filter box, and the arc-shaped end of the arc-shaped block contacts the protruding end of the cam. A movable rod is fixedly connected to the other end of the arc-shaped block, a fixed plate is fixedly connected to the other side of the filter box, and a round hole is drilled on one side of the fixed plate. A U-shaped plate is fixedly connected to the end of the movable rod away from the arc-shaped block, and multiple collision balls are fixedly connected to the side of the U-shaped plate close to the filter box. A spring is sleeved on the outer wall of the movable rod, and the two ends of the spring are fixedly connected to the ends of the arc-shaped block and the fixed plate respectively.

[0017] Furthermore, a sliding block is fixedly connected to the bottom end of the arc-shaped block, and a groove is chiseled at the top of the filter box, with the bottom end of the sliding block located in the groove and slidably connected thereto.

[0020] 1. This technical solution, through its flushing and brushing mechanism, can spray water upwards from multiple flushing nozzles to flush the anthracite coal seam, quartz sand layer, and garnet layer. At the same time, it drives a pair of cleaning brushes to scrub the top anthracite coal seam. This allows for auxiliary cleaning when the anthracite coal seam furthest from the flushing nozzles is not flushed sufficiently during the flushing process, thus compensating for the lack of thorough flushing at the top and making the cleaning more complete and comprehensive.

[0021] 2. This technical solution uses a vibration-assisted mechanism to generate vibration by repeatedly colliding multiple impact balls with the compression of a cam and the elasticity of a spring. The vibration is transmitted to the anthracite layer, quartz sand layer and garnet layer, which loosens the impurities clogging the micropores so that they can be washed away by water or brushes, making the cleaning more thorough and reducing residue.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0034] Please see Figures 1-5 As shown, the present invention provides a multi-media filtration device for wastewater treatment, comprising:

[0035] Filter box 1, with an inlet pipe 2 fixedly connected to one side of filter box 1, and the interior of filter box 1 is arranged from top to bottom as follows: anthracite layer 4, quartz sand layer 5 and garnet layer 6.

[0036] The flushing and brushing mechanism 10 is installed on the filter box 1 and is used for cleaning the anthracite coal seam 4, the quartz sand layer 5 and the garnet layer 6.

[0037] Vibration auxiliary mechanism 11 is located on the outside of filter box 1 and is used to assist in the cleaning of anthracite coal seam 4, quartz sand layer 5 and garnet layer 6.

[0038] The flushing and brushing mechanism 10 includes a water guide pipe 1001 embedded and connected to one side of the filter box 1. Multiple flushing nozzles 1002 are fixedly connected to the outer wall of the water guide pipe 1001. An L-shaped plate 1003 is fixedly connected to the top of the filter box 1, and a motor 1004 is fixedly connected to the inner top of the L-shaped plate 1003. A rotating rod 1005 is rotatably connected to the top of the filter box 1 through a bearing. The top of the rotating rod 1005 is fixedly connected to the output end of the motor 1004. A pair of cleaning brushes 1006 are fixedly connected to the outer wall of the rotating rod 1005, and the bottom ends of the pair of cleaning brushes 1006 are in contact with the top of the anthracite coal layer 4.

[0039] In the specific implementation process, sewage enters the filter box 1 through the inlet pipe 2. First, it passes through the anthracite layer 4 to intercept large suspended particles, reducing the load on subsequent filter layers. Then, it passes through the quartz sand layer 5 to remove medium suspended particles. Next, it passes through the garnet layer 6 to filter out fine particles, which fall to the bottom of the filter box 1. When it needs to be rinsed, the water pipe 1001 is connected to an external water pipe to supply water, which is sprayed upward through multiple rinsing nozzles 1002, rushing towards the garnet layer 6, quartz sand layer 5 and anthracite layer 4 to rinse away the impurities. At the same time, during the rinsing process, the anthracite layer 4 is the farthest from the rinsing nozzles 1002, and the rinsing effect is insufficient. At this time, the drive motor 1004 drives the rotating rod 1005 to rotate, which drives a pair of cleaning brushes 1006 to brush the top anthracite layer 4, making up for the deficiency of insufficient rinsing at the top and making the cleaning more thorough and comprehensive.

[0040] The inner wall of the water inlet pipe 2 is fixedly connected to a filter screen 3, and the filter screen 3 is located at the top of the anthracite coal seam 4.

[0041] By setting up filter screen 3, coarse impurities such as leaves and plastic fragments in the sewage can be filtered and intercepted, reducing the risk of blockage in the anthracite coal seam 4, quartz sand layer 5, and garnet layer 6.

[0042] Among them, T-shaped sealing blocks 7 are fixedly connected to one side of the anthracite coal seam 4, the quartz sand layer 5 and the garnet layer 6. Three guide holes are drilled on the side of the filter box 1 near the T-shaped sealing block 7, and the outer wall of the T-shaped sealing block 7 is in close contact with the inner wall of the guide hole. The three T-shaped sealing blocks 7 are all connected to the filter box 1 by bolts.

[0043] The T-shaped sealing block 7 can be easily installed and removed from the filter box 1 via a detachable bolt connection, which facilitates the disassembly and separation of the anthracite layer 4, quartz sand layer 5, and garnet layer 6 for replacement.

[0044] The filter box 1 has three pairs of guide grooves 9 carved into its inner wall, and each pair of guide grooves 9 has a guide block 8 in contact with it. The opposite sides of the three pairs of guide blocks 8 are fixedly connected to the outer walls of the anthracite layer 4, the quartz sand layer 5 and the garnet layer 6, respectively.

[0045] Anthracite layer 4, quartz sand layer 5 and garnet layer 6 extend into the filter box 1 and move along the guide groove 9 via guide block 8, so as to make stable movement under the guidance of guide block 8 and guide groove 9 and not easily deviate. Specific Implementation Example 2:

[0047] Please see Figure 1 and Figures 3-5As shown, in a preferred embodiment, the vibration assist mechanism 11 includes a cam 1101 sleeved on the outer wall of the rotating rod 1005, an arc-shaped block 1102 slidably connected to the top of the filter box 1, and the arc-shaped end of the arc-shaped block 1102 contacts the protruding end of the cam 1101. The other end of the arc-shaped block 1102 is fixedly connected to a movable rod 1103. The other side of the filter box 1 is fixedly connected to a fixed plate 1104, and a round hole is drilled on one side of the fixed plate 1104. The end of the movable rod 1103 away from the arc-shaped block 1102 is fixedly connected to a U-shaped plate 1106, and a plurality of collision balls 1107 are fixedly connected to the side of the U-shaped plate 1106 close to the filter box 1. A spring 1105 is sleeved on the outer wall of the movable rod 1103, and the two ends of the spring 1105 are fixedly connected to the ends of the arc-shaped block 1102 and the fixed plate 1104 respectively.

[0048] In the specific implementation process, the rotating rod 1005 drives the cam 1101 to rotate. During the rotation of the cam 1101, its convex end squeezes the arc-shaped block 1102 to one side, which drives the movable rod 1103 and the U-shaped plate 1106 to move to one side and stretches the spring 1105. This causes the multiple collision balls 1107 to separate from one side of the filter box 1. Then, after the cam 1101 rotates away from the arc-shaped block 1102, the elastic reset action of the spring 1105 drives the arc-shaped block 1102 to reset. This causes the multiple collision balls 1107 to reset through the movable rod 1103 and the U-shaped plate 1106 and come into contact with and collide with one side of the filter box 1. This process is repeated, causing the filter box 1 to vibrate under the repeated collisions of the multiple collision balls 1107. The vibration is transmitted to the anthracite layer 4, the quartz sand layer 5, and the garnet layer 6, which loosens the impurities blocking the micropores so that they can be washed away by water or the brush body. This makes the cleaning more thorough and complete, and reduces residue.

[0049] The bottom end of the arc-shaped block 1102 is fixedly connected to a sliding block 1108, the top end of the filter box 1 is chiseled with a groove 1109, and the bottom end of the sliding block 1108 is located in the groove 1109 and is slidably connected to it.

[0050] By setting up the sliding block 1108 and the groove 1109, the movement of the arc block 1102 can be assisted by sliding, so that the arc block 1102 can maintain stable movement.

[0051] The bottom of the filter box 1 is fixedly connected to a water outlet pipe 12, and the outer wall of the water outlet pipe 12 is fixedly connected to a clean water pipe 13 and a sewage pipe 15, respectively. The outer wall of the clean water pipe 13 is fixedly connected to a first control valve 14, and the outer wall of the sewage pipe 15 is fixedly connected to a second control valve 16.

[0052] When draining clean water, open the first control valve 14 and close the second control valve 16, so that the filtered clean water is discharged outward through the outlet pipe 12 and the clean water pipe 13. When draining flushing wastewater, close the first control valve 14 and open the second control valve 16, so that the flushing wastewater is discharged outward through the outlet pipe 12 and the wastewater pipe 15.

[0053] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0054] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0055] The working principle of this utility model is as follows:

[0056] In use, wastewater enters the filter box 1 through the inlet pipe 2. It first passes through the anthracite layer 4 to intercept large suspended particles, reducing the load on subsequent filter layers. Then, it passes through the quartz sand layer 5 to remove medium-sized suspended particles. Next, it passes through the garnet layer 6 to filter out fine particles, which fall to the bottom of the filter box 1. The first control valve 14 is opened, and the second control valve 16 is closed, allowing the filtered clean water to be discharged through the outlet pipe 12 and the clean water pipe 13. During rinsing, the guide pipe 1001... Water is supplied through an external water pipe and sprayed upwards through multiple flushing nozzles 1002, washing away impurities from the garnet layer 6, quartz sand layer 5, and anthracite layer 4. During the flushing process, the anthracite layer 4 is furthest from the flushing nozzles 1002, resulting in insufficient flushing effect. At this point, the drive motor 1004 rotates the rotating rod 1005, causing it to drive a pair of cleaning brushes 1006 to scrub the top anthracite layer 4. Simultaneously, the rotation of the rotating rod 1005 drives the cam 110... 1. Rotation causes the cam 1101 to rotate, during which its protruding end presses against the arc-shaped block 1102, moving it to one side. This causes the movable rod 1103 and the U-shaped plate 1106 to move to one side, stretching the spring 1105 and causing multiple collision balls 1107 to separate from one side of the filter box 1. Then, after the cam 1101 rotates away from the arc-shaped block 1102, the elastic reset action of the spring 1105 causes the arc-shaped block 1102 to reset, allowing it to move through the movable rod 1103 and the U-shaped plate 1106 to one side. 6 drives multiple collision balls 1107 to reset and collide with one side of the filter box 1. This process is repeated, causing the filter box 1 to vibrate under the repeated collisions of multiple collision balls 1107. The vibration is transmitted to the anthracite layer 4, the quartz sand layer 5 and the garnet layer 6, which loosens the impurities blocking the micropores so that they can be washed away by water or the brush body. Then, the first control valve 14 is closed and the second control valve 16 is opened, so that the flushed wastewater is discharged outward through the outlet pipe 12 and the sewage pipe 15.
