Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel filter technology, specifically a sand and gravel filter that can evenly distribute water. Background Technology
[0002] A sand filter, also known as a quartz sand filter or sand filter, is a three-dimensional, deep-layer filter that uses a homogeneous, uniformly sized quartz sand bed as the filter medium for filtration. It is commonly used for primary filtration. It primarily uses sand and gravel as the filter media. As a type of media filter, the sand bed provides three-dimensional filtration, possessing a strong ability to trap contaminants. It is suitable for deep well water filtration, agricultural water treatment, and pretreatment in various water treatment processes. It can be used in factories, rural areas, hotels, schools, horticultural farms, water plants, and various other locations. Among all filters, sand filters are most effective at treating both organic and inorganic impurities in water. These filters have a strong ability to filter out and retain impurities and can provide uninterrupted water supply.
[0003] Currently, most existing water distribution devices for filters are integrated with the filters, making them inconvenient to clean and replace, and thus having poor applicability.
[0004] Therefore, a sand filter capable of uniformly distributing water is proposed to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a sand and gravel filter that can uniformly distribute water, including an outer shell, a cover on the top of the outer shell, a filter plate at the bottom of the inner side of the outer shell, sand and gravel filler on top of the filter plate, a stepped groove inside the top of the outer shell, an annular plate inside the stepped groove, water distribution pipes arranged in a cross shape inside the annular plate, multiple water distribution pipes connected to a multi-pipe connection assembly on the side away from the annular plate, an inlet pipe connected to the top of the multi-pipe connection assembly, the inlet pipe passing through a through hole inside the cover and extending to the top of the cover, an outlet pipe at the bottom of the outer shell, and a control valve on the outlet pipe.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0007] This utility model incorporates a multi-pipe connection assembly, an inlet pipe, a water distribution pipe, and an annular plate. Water is introduced through the inlet pipe, and the water distribution pipes are arranged in a cross shape, allowing water to flow out through the outlet holes, thus achieving uniform water distribution.
[0008] This utility model features an edge plate 1, an edge plate 2, fastening bolts, and a stepped groove. By removing the fastening bolts, the edge plate 1 and the edge plate 2 can be separated, and the cover can be opened. This allows the annular plate to be easily removed from the stepped groove and the liquid inlet pipe to be removed from the cover, facilitating the cleaning and replacement of the water distribution device.

[0015] 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.
[0016] As attached Figure 1-4 As shown, the present invention provides a sand and gravel filter capable of uniformly distributing water, comprising an outer shell 1, a shell cover 3 on the top of the outer shell 1, a filter plate 15 at the bottom of the inner side of the outer shell 1, sand and gravel filler 14 on the top of the filter plate 15, a stepped groove 101 inside the top of the outer shell 1, an annular plate 13 inside the stepped groove 101, water distribution pipes 12 arranged in a cross shape inside the annular plate 13, the side of the multiple water distribution pipes 12 away from the annular plate 13 being connected to a multi-pipe connection assembly 10, the top of the multi-pipe connection assembly 10 being connected to an inlet pipe 8, the inlet pipe 8 penetrating through a through hole 301 inside the shell cover 3 and extending to the top of the shell cover 3, an outlet pipe 16 at the bottom of the outer shell 1, and a control valve 161 on the outlet pipe 16.
[0017] Specifically, support legs 2 are provided on both sides of the lower part of the outer shell 1.
[0018] Specifically, a sealing ring groove 102 is provided inside the upper part of the outer shell 1, and a sealing ring groove 302 is provided inside the lower part of the shell cover 3. After the sealing ring groove 102 and the sealing ring groove 302 are combined, a sealing ring 9 is provided inside.
[0019] Specifically, an edge plate 2 5 is provided on the upper exterior of the outer shell 1, and an edge plate 1 4 is provided on the lower exterior of the shell cover 3. The edge plate 1 4 and the edge plate 2 5 are connected by a plurality of fastening bolts 6 and nuts 7.
[0020] Specifically, a sealing ring 11 is provided at the contact point between the shell cover 3 and the inside of the liquid inlet pipe 8.
[0021] Specifically, the bottom of the water distribution pipe 12 is provided with multiple water outlet holes 121.
[0022] Working principle: When in use, water is sent in through the inlet pipe 8, and the water is distributed into the water distribution pipe 12 through the multi-pipe connection assembly. The water flows out through the water distribution hole 12 and is evenly distributed. After being filtered by the sand and gravel packing, the water is sent out through the leakage plate 15 and finally sent out through the outlet pipe 16.
[0023] When the water distribution structure needs to be cleaned and replaced, remove the fastening bolts 6, separate the edge plate 4 and the edge plate 5, and then open the cover 3. This makes it easy to remove the annular plate 13 from the stepped groove 101 and the liquid inlet pipe from the cover, which facilitates the cleaning and replacement of the water distribution device.
