Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a modular shallow sand filter. Background Art

[0002] Shallow sand filters are mainly used for filtering circulating water, water supply, and wastewater in the industrial field. HGBMF's media filtration system uses deep media to effectively remove particulate matter and reduce turbidity. If specific filter materials such as activated carbon, zeolite, etc. are installed, the corresponding organic matter, ions, etc. can also be adsorbed and removed. The fluidization device (bottom drainage device) in the system can fluidize the filter medium, remove the pollutants trapped on the medium, and discharge them for thorough cleaning.

[0003] At present, a single shallow sand filter is directly connected to the subsequent filtering equipment. If the shallow sand filter is damaged, the subsequent equipment will not be able to operate, which will greatly affect the operation of the subsequent equipment. It is very inconvenient to disassemble and is very time-consuming and laborious. Therefore, we need a modular shallow sand filter to solve the above-mentioned problem of being difficult to disassemble and repair after damage. Utility Model Content

Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present utility model, should still fall within the scope of the technical contents disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the present specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present utility model. The change or adjustment of the relative relationship, without substantial change of the technical contents, should also be regarded as the scope of the implementation of the present utility model.

[0018] Embodiment 1: Figure 1 The front view of a modular shallow sand filter is shown, and the device includes: an equipment body 2, a pipe connecting device, an inlet pipe 1 and an outlet pipe 3, and the equipment body 2 is connected to the inlet pipe 1 and the outlet pipe 3 through the pipe connecting device. A bracket is provided at the bottom of the equipment body 2, and the equipment body 2 is placed on the ground through the bracket. A water valve 8 is provided at the connection between the pipe connecting device and the inlet pipe 1. The water to be filtered will enter each equipment body 2 from the inlet pipe 1 for filtration, and the filtered water will be collected in the outlet pipe 3 and flow to the next treatment device. A separate water valve 8 is provided upstream of each equipment body 2. When any of the equipment bodies 2 needs to be replaced or repaired, the water valve 8 can be closed and then disassembled without affecting the overall use.

[0019] Figure 2 , Figure 3The utility model shows a pipeline connection device, one of the core components of the utility model, which includes: a first pipeline 4, a pipeline fixing sleeve 5 and a second pipeline 7. The front end of the first pipeline 4 is embedded in the second pipeline 7. A second sealing ring 54 is provided at the joint between the outer wall of the first pipeline 4 and the inner wall of the second pipeline 7. The second sealing ring 54 is used to ensure the sealing between the two pipelines. The outer wall of the second pipeline 7 is provided with an external thread. The pipeline fixing sleeve 5 is sleeved on the first pipeline 4. The inner wall of the pipeline fixing sleeve 5 is provided with a slot hole. The slot hole is provided with a second sealing ring 54. A spring 51 is provided, one end of the spring 51 is connected to the bottom surface of the slot, and the other end of the spring 51 is provided with a pressing plate 52. A first sealing ring 53 is provided on the pressing plate 52. The first sealing ring 53 is squeezed at the connection between the first pipe 4 and the second pipe 7 by the elastic force of the spring 51, so as to further enhance the sealing between the two. The pressing plate 52 and the first sealing ring 53 are both annular and sleeved on the first pipe 4. An internal thread is provided on the inner wall of the end of the pipe fixing sleeve 5 away from the slot, and the pipe fixing sleeve 5 is threadedly connected with the second pipe 7. A grip 6 is provided on the outer wall of the pipe fixing sleeve 5. By rotating the grip 6, the pipe fixing sleeve 5 can drive the first pipe 4 to gradually move along the thread, so that the first sealing ring 53 is gradually squeezed more thoroughly until the rotation is forced to a suitable position, so as to ensure the sealing of the connection between the first pipe 4 and the second pipe 7. A clamp is provided on the outer wall of the pipe fixing sleeve 5. The clamp can be used for the final fixation, so as to further maintain the stability of the connection between the first pipe 4 and the second pipe 7.

[0020] Working principle: When the equipment body 2 is damaged and needs to be disassembled for maintenance, first close the corresponding water valve 8, and then disassemble the pipe connecting device. First loosen the clamp, then hold the handle 6 and rotate it counterclockwise to allow the pipe fixing sleeve 5 to loosen from the second pipe 7 along the thread. After completely loosening, the first pipe 4 and the second pipe 7 can be separated. In this way, the equipment body 2 and the water inlet pipe 1 and the water outlet pipe 3 can be separated very quickly and conveniently, and the equipment body can be replaced or repaired without delaying the normal operation of subsequent equipment.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
