Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to an enhanced sand and gravel filter. Background Technology

[0002] A sand filter, also known as a quartz sand filter, is a three-dimensional deep filtration filter that uses a sand bed of homogeneous quartz sand of equal particle size as the filter medium. It mainly uses sand and gravel as the filter media and is often used in the primary filtration stage of deep well water filtration and agricultural water treatment. It has the advantages of low cost and high filtration efficiency.

[0003] However, the inlet pipe of the existing device is in a fixed position, and the sand and gravel will always be flushed and filtered in one place during filtration. The impact of the water flow will cause the sand and gravel to be unevenly distributed, which will reduce the filtration effect and affect the quality of the outflowing water. Moreover, after a long period of filtration, impurities will accumulate in the sand and gravel, and the backwashing cleaning will not be thorough enough, which will affect the filtration effect. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, one of the objectives of this utility model is to provide an enhanced sand and gravel filter. Through the configured filter components and buffer plate, during use, water flows into the housing through the inlet pipe. The buffer plate, with its central protrusion, diverts and buffers the water flow. The diverted water flows out through distributed water holes, buffering the impact force while evenly distributing the water flow to various parts. The water then undergoes two-stage filtration through two layers of filter components, preventing uneven distribution caused by water flow dispersion, improving filtration efficiency, and ensuring water quality. The inner cylinder, sliding groove, and limiting groove allow for easy removal of the filter components and the removal of the filter screen for thorough rinsing and cleaning of the sand and gravel filter media, ensuring filtration quality.

[0005] One of the objectives of this utility model is achieved by the following technical solution: a reinforced sand and gravel filter, comprising: a shell, a bracket fixedly connected to the outer side wall of the shell, an inner cylinder provided inside the shell, symmetrically provided sliding grooves on the inner side wall of the inner cylinder, each of the sliding grooves having a limiting groove II on the middle inner side wall, the two limiting grooves II being arranged in a rotationally symmetrical manner, two sets of filter components provided inside the inner cylinder, the limiting groove II being in limiting cooperation with the upper filter component, the filter components being in sliding cooperation with the limiting groove II, a water outlet pipe being connected through the bottom end of the shell, a cover being fixedly installed on the top end of the shell, a buffer plate being fixedly connected to the inner side wall of the cover, a plurality of water passage holes being evenly provided on the buffer plate, and a water inlet pipe being connected through the top end of the cover;

[0006] The filter assembly includes a filter housing filled with sand and gravel filter media. A filter screen covers the sand and gravel filter media, and a handle is fixed to the upper surface of the filter screen. The left and right sidewalls of the filter housing are symmetrically equipped with limiting protrusions, and the bottom of the filter housing has several filter holes. Through the filter assembly and buffer plate, during use, water flows into the housing through the inlet pipe. The buffer plate, through the central protrusion, diverts and buffers the water flow. The diverted water flows out through the distributed water holes, buffering the impact force while evenly distributing the water flow to various parts. The water then undergoes two-stage filtration through the two layers of filter assembly, preventing uneven distribution caused by water flow dispersion, improving filtration efficiency, and ensuring water quality. The inner cylinder, sliding groove, and limiting groove allow the filter assembly to be removed, and the filter screen can be removed for thorough rinsing and cleaning of the sand and gravel filter media, ensuring filtration quality.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-5 This utility model discloses an enhanced sand and gravel filter, comprising: a shell 1, a bracket 2 fixedly connected to the outer wall of the shell 1, mounting plates welded to the bottom ends of the support legs of the bracket 2, an inner cylinder 6 inside the shell 1, a limiting ring 601 at the top of the inner cylinder 6, a limiting groove 101 at the top of the shell 1, the limiting groove 101 being adapted to the shape of the limiting ring 601, and symmetrical sliding grooves 602 on the inner sidewall of the inner cylinder 6, with a second limiting groove 602 on the middle inner sidewall of each sliding groove 602. 3. The two limiting grooves 603 are arranged in a rotationally symmetrical manner. The inner cylinder 6 is provided with two sets of filter components 7, one upper and one lower. The limiting groove 603 is matched with the upper filter component 7. The filter components 7 are all slidably matched with the limiting groove 603. The bottom end of the shell 1 is connected to the water outlet pipe 5. The top end of the shell 1 is fixedly installed with the cover 3. The inner side wall of the cover 3 is fixedly connected to the buffer plate 8. The middle of the buffer plate 8 is provided with a protrusion. Several water passage holes 801 are evenly opened on the buffer plate 8. The top end of the cover 3 is connected to the water inlet pipe 4.

[0022] The filter assembly 7 includes a filter housing 701, which is filled with sand and gravel filter media 703. A filter screen 704 covers the top of the sand and gravel filter media 703. A handle 705 is fixed to the upper surface of the filter screen 704. The left and right side walls of the filter housing 701 are symmetrically provided with limiting protrusions 702. The limiting protrusions 702 are slidably adapted to the sliding groove 602 and the limiting groove 603. The bottom end of the filter housing 701 is provided with a number of filter holes 7011. With the configured filter assembly 7 and buffer plate 8, during use, water flows into the housing 1 through the inlet pipe 4. The buffer plate 8 uses a central protrusion to divert and buffer the water flow. The diverted water flows out through distributed water passages 801, buffering the impact force while evenly distributing the water flow to various parts. Then, the water flows through two layers of filter assembly 7 for two-stage filtration. The sand and gravel filter media 703 filters impurities in the water flow, and the filter screen 704 protects the sand and gravel filter media 703 to prevent it from being dispersed by the water flow and causing uneven distribution. To improve filtration efficiency and ensure water quality, the inner cylinder 6, sliding groove 602, and limiting groove 603 are used to clean impurities in the sand and gravel filter media 703. To remove the inner cylinder 6, open the cover 3 and remove the upper filter assembly 7. Then, use the handle 705 to rotate the filter assembly 7 until the limiting protrusion 702 aligns with the sliding groove 602. This allows the upper and lower filter assemblies 7 to be slid out together. Finally, remove the filter screen 704 to thoroughly rinse and clean the sand and gravel filter media 703, ensuring filtration quality.

[0023] Working principle: During use, water flows into the housing 1 through the inlet pipe 4. The buffer plate 8 diverts and buffers the water flow through the central protrusion. The diverted water flows out through the distributed water holes 801. While buffering the impact force, the water flow is evenly distributed in various parts. Then, the water flows through two layers of filter components 7 for two-stage filtration. The sand and gravel filter media 703 filters impurities in the water flow, and the filter screen 704 protects the sand and gravel filter media 703 to prevent it from being dispersed by the water flow and causing uneven distribution, thereby improving the filtration effect and ensuring the quality of the output water.

[0024] When cleaning the impurities in the sand and gravel filter media 703, open the cover 3 and take out the inner cylinder 6. When taking out the upper filter component 7, use the handle 705 to rotate the filter component 7 until the limit protrusion 702 is aligned with the slide groove 602. Then, the upper and lower filter components 7 can be slid out together. After removing the filter screen 704, the sand and gravel filter media 703 can be thoroughly rinsed and cleaned.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
