Description

Technical Field

[0001] This utility model relates to the field of water purification and filtration technology, specifically to a shallow media filter for water pretreatment. Background Technology

[0002] The core purpose of water pretreatment is to remove impurities from the water, ensuring the proper functioning of subsequent treatment steps and improving the final water quality. Pretreatment removes suspended solids, organic matter, microorganisms, heavy metals, and other pollutants from the water through various methods, creating better conditions for subsequent purification steps. It should include three main components:

[0003] Pretreatment filtration requires multiple filtration processes involving quartz sand, activated carbon, and cation exchange resin. During long-term use, the filter media needs to be replaced regularly. However, the replacement of conventional pretreatment filtration equipment requires the removal of all internal filter elements, which is time-consuming and troublesome. Therefore, we propose a shallow media filter for water pretreatment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a shallow media filter for water pretreatment. The filter media is easy to replace through the pull-out filter media drawer. At the same time, the sewage stays in the equipment for a longer time, and the treatment is more thorough. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shallow media filter for water pretreatment, comprising a housing and a connecting mechanism;

[0006] Casing: Its interior is slidably connected with a uniformly distributed medium filling mechanism;

[0007] Connection mechanism: It includes a support frame, a disc, a connecting plate, a cylinder, and a hose assembly. Two adjacent media filling mechanisms are connected by the hose assembly. The two hose assemblies are staggered. The front and rear inner walls of the outer shell are provided with vertically distributed supports. The middle of each support frame is rotatably connected to a disc via a rotating shaft. The upper and lower ends of the disc are rotatably connected to connecting plates via pins. The two connecting plates on the same disc are rotatably connected to the upper and lower ends of the adjacent hose assembly. The pull-out filter media drawer facilitates the replacement of the filter media. At the same time, the sewage stays inside the equipment for a longer time, resulting in more thorough treatment.

[0008] Furthermore, the media filling mechanism includes drawers, connecting ports, and caps. Drawers are slidably connected inside the outer shell, and caps are fixedly connected to the right side of each drawer. Connecting ports are symmetrically distributed at both the top and bottom of the drawers to achieve filtration.

[0009] Furthermore, both the upper and lower ends of the outer shell are threaded with connecting pipes, which are respectively connected to vertically adjacent connecting ports. The two connecting pipes are provided with wrenches symmetrically distributed at opposite outer ends to achieve communication with external pipes.

[0010] Furthermore, the medium filling mechanism also includes end caps, which are threaded to the outside of the connection ports that are not connected to the hose assembly and those that are not connected to the connecting pipe, respectively, to block the drawer.

[0011] Furthermore, the flexible hose assembly includes a telescopic flexible hose, a positioning plate, a silicone sealing ring, and a sealing seat. Sealing seats are fixedly connected to both the upper and lower ends of the telescopic flexible hose. Two sealing seats located on the same telescopic flexible hose are respectively inserted into the interior of vertically adjacent connection ports. The two telescopic flexible hoses are staggered. A silicone sealing ring is movably fitted onto the outer arc surface of each sealing seat, and the silicone sealing ring contacts the inner wall of each adjacent connection port. Positioning plates are fixedly fitted to both the upper and lower ends of the telescopic flexible hose, and the positioning plates are located inside the two sealing seats. A cylinder is fixedly connected to the opposite outer surfaces of the two positioning plates located on the same telescopic flexible hose, enabling communication between different drawers.

[0012] Furthermore, the connecting mechanism also includes sliding columns and brackets. Two brackets are arranged in pairs between the inner walls of the front and rear sides of the outer shell. The telescopic hoses are located between the two brackets in the same group. Sliding columns are fixedly connected to the middle of each bracket in the front and rear symmetrically distributed. The upper and lower ends of the sliding columns of the brackets in the same group are slidably connected to the sliding holes on the edges of adjacent positioning plates to fix the sealing seat position and facilitate the alignment of the connection port.

[0013] Furthermore, the connecting mechanism also includes a worm and a worm wheel. The inner walls of the front and rear sides of the outer shell are rotatably connected by worms distributed vertically. The inner ends of the two rotating shafts are fixedly fitted with worm wheels. The worms are respectively meshed with the adjacent worm wheels. The front end of each worm is fixedly fitted with an adjustment knob. The adjustment knobs are located on the front side of the outer shell and drive the disc to rotate.

[0014] Furthermore, the front side of the outer casing is provided with observation windows distributed vertically, which correspond to the front and rear positions of the adjacent telescopic hoses to observe the position of the sealing seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This shallow media filter for water pretreatment has the following advantages:

[0016] 1. When the filter media needs to be replaced, turn the adjustment knob in the opposite direction to move the two positioning plates located on the same telescopic hose between the same set of sliding columns and bring them closer to each other. The sealing seat will disengage from the vertically adjacent connection port. Turn the connecting pipe with a wrench to disengage from the vertically adjacent connection port. Then pull out the drawer, open the cover and replace the filter media. It is convenient and simple.

[0017] 2. Wastewater flows out in an "S" shape through the integrated system of drawers and flexible hoses, extending the residence time of wastewater in various filter media and achieving more thorough wastewater treatment. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a shallow media filter for water pretreatment, including a housing 1 and a connecting mechanism 3;

[0025] The outer casing 1 has a media filling mechanism 2 that is slidably connected inside. The media filling mechanism 2 includes drawers 21, connection ports 23 and caps 24. The drawers 21 are slidably connected inside the outer casing 1. Each drawer 21 has a cap 24 fixedly connected to its right side. Each drawer 21 has a symmetrically distributed connection port 23 at both the top and bottom. Each of the top and bottom of the outer casing 1 is threaded with a connecting pipe 4. The connecting pipe 4 is connected to the vertically adjacent connection port 23. Each of the two connecting pipes 4 has a wrench 5 symmetrically distributed at the opposite outer ends. The media filling mechanism 2 also includes an end cap 22. The end cap 22 is threaded to the outside of the connection port 23 that is not connected by the hose assembly 38 and is not connected by the connecting pipe 4. The sewage passes through the whole consisting of each drawer 21 and the telescopic hose 381 in an "S" shape to achieve filtration. When changing the filter media, the drawer 21 is pulled out and the cap 24 is opened to change the filter media.

[0026] Connection mechanism 3: It includes a bracket 32, a disc 34, a connecting plate 36, a cylinder 37, and a hose assembly 38. Two adjacent media filling mechanisms 2 are connected by the hose assembly 38, which is staggered. A bracket 32 ​​is vertically distributed between the front and rear inner walls of the outer casing 1. The middle of each bracket 32 ​​is rotatably connected to a disc 34 via a pivot. The upper and lower ends of each disc 34 are rotatably connected to a connecting plate 36 via pins. Two connecting plates 36 located on the same disc 34 are rotatably connected to the upper and lower ends of adjacent hose assemblies 38. The hose assembly 38 includes a telescopic hose 381, a positioning plate 382, ​​a silicone sealing ring 383, and a sealing seat 384. Both ends of the telescopic hose 381 are fixedly connected to sealing seats 384. Two sealing seats 384 located on the same telescopic hose 381 are respectively inserted into the interior of vertically adjacent connection ports 23. The two telescopic hoses 381 are staggered. The outer arc surface of each sealing seat 384 is movably fitted with a silicone sealing ring 383. The silicone sealing ring 383 contacts the inner wall of the adjacent connection port 23. Both ends of the telescopic hose 381 are fixedly fitted with positioning plates 382. The positioning plates 382 are located on the inner side of the two sealing seats 384. The cylinder 37 is fixedly connected to the opposite outer sides of the two positioning plates 382 located on the same telescopic hose 381. The connecting mechanism 3 also includes a sliding column 33 and a bracket 39. The inner walls of the front and rear sides of the outer casing 1 are provided with two sets of brackets 39 arranged vertically. Telescopic hoses 381 are located between two brackets 39 in the same set. Each bracket 39 has a symmetrically distributed sliding column 33 fixedly connected to its center. The upper and lower ends of the sliding columns 33 in the same set are slidably connected to the sliding holes along the edges of adjacent positioning plates 382. The connecting mechanism 3 also includes a worm gear 31 and a worm wheel 35. The inner walls of the front and rear sides of the outer casing 1 are rotatably connected with vertically distributed worm gears 31. Worm wheels 35 are fixedly fitted onto the opposite inner ends of the two rotating shafts. The worm gears 31 mesh with adjacent worm wheels 35. Adjustment knobs are fixedly fitted onto the front ends of the worm gears 31. All knobs are located on the front side of the outer casing 1. The front side of the outer casing 1 has observation windows 6 distributed vertically. The observation windows 6 correspond to the front and rear positions of the adjacent telescopic hoses 381. When the adjustment knob is turned, the worm gear 31 rotates, which drives the meshing worm wheel 35 to rotate. The disc 34 rotates, and the connecting plate 36 rotates synchronously. This causes the two positioning plates 382 located on the same telescopic hose 381 to slide and separate between the same set of sliding columns 33. This causes the sealing seat 384 to be inserted into the interior of the vertically adjacent connection port 23. The silicone sealing ring 383 prevents leakage. The position of the sealing seat 384 can be observed through the observation window 6 to ensure that the sealing seat 384 is fully inserted into the interior of the vertically adjacent connection port 23, thus achieving communication.

[0027] The working principle of the shallow media filter for water pretreatment provided by this utility model is as follows: The drawer 21 from top to bottom is filled with quartz sand, activated carbon, and cation exchange resin respectively. Then, turning the adjustment knob rotates the worm gear 31, which drives the meshing worm wheel 35 to rotate. The disc 34 rotates, and the connecting plate 36 rotates synchronously. This causes the two positioning plates 382 located on the same telescopic hose 381 to slide and separate between the sliding columns 33 in the same group. This causes the sealing seat 384 to be inserted into the interior of the vertically adjacent connecting port 23. The silicone sealing ring 383 prevents leakage. The position of the sealing seat 384 can be observed through the observation window 6. Ensure that the sealing seat 384 is fully inserted into the vertically adjacent connection port 23. The upper connecting pipe 4 connects to the sewage pipe. The sewage passes through the whole consisting of each drawer 21 and the telescopic hose 381 in an "S" shape to achieve filtration. When the filter medium needs to be replaced, turn the adjustment knob in the opposite direction. Similarly, the two positioning plates 382 located on the same telescopic hose 381 slide between the same set of sliding columns 33 and move closer to each other. The sealing seat 384 disengages from the vertically adjacent connection port 23. Turn the connecting pipe 4 with the wrench 5 to disengage from the vertically adjacent connection port 23. Then, pull out the drawer 21 and open the cover 24 to replace the filter medium.
