Description

Technical Field

[0001] The present application relates to the field of water treatment technology, and in particular to an assembled stainless steel filter plate. Background Art

[0002] Filter tanks are widely used in water treatment technology. Their function is to remove particulate impurities from water through the filtration and adsorption of filter media such as quartz sand, anthracite, or activated carbon. Filter tanks are generally the last step in the water treatment process and the final checkpoint for water quality. The filter media in the filter tank requires structural support at the bottom to separate it from the filtered water. The support structure beneath the filter media in this filter tank is the filter plate. Traditionally, filter plates consisted of reinforced concrete slabs with a certain strength and rigidity, and plastic filter heads mounted on the concrete slab. The plastic filter heads have narrow slits that ensure water flow above and below the filter plate, ensuring connectivity between the filter head slits. These slits also prevent filter media from leaking through the slits and into the filter plate.

[0003] Some filter plates currently in use domestically include those made of fiberglass and plastic. Compared to concrete filter plates, these offer advantages such as light weight and ease of installation. However, their inherent strength and rigidity are insufficient. When used within a filter tank and subjected to long-term pressure from both upper and lower directions, the gaps in the filter plates can easily fatigue and cause water and air leakage. Furthermore, after a period of use, the plates can bend or even break due to their lack of rigidity, resulting in poor flatness and uneven water and air distribution within the filter tank, impacting normal operation and water quality and quantity. Furthermore, fiberglass and plastic filter plates, when used in water treatment project filters, present health and safety risks. While non-reinforced concrete filter plates made of fiberglass and plastic have been used in projects, these filters have not been widely adopted due to their inherent mechanical strength limitations and inadequate sealing with concrete. As a water treatment engineering structure, the filter tank has a design life of more than several decades. However, as an important structure in the filter tank, the filter head plate water distribution system is restricted by the materials used and the construction technology. Whether it is a reinforced concrete filter plate or other internal non-metallic filter plate, its service life is only about ten years at most compared with the service life of the filter tank. During the service life of the filter tank, the filter head plate water distribution system needs to be replaced many times, which seriously affects the water quality and quantity, and increases repeated investment.

[0004] There is currently no stainless steel filter plate with higher strength. Utility Model Content

[0044] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] Reference Figures 1-8 An assembled stainless steel filter plate comprises a filter plate body 11 and a connecting plate 12. The filter plate body 11 is a corrugated stainless steel plate formed in one piece by mechanical stamping. The filter plate body 11 is a wavy stainless steel plate with a flat crest and an arc-shaped trough. A plurality of jacks 14 are evenly spaced on the top wall of the filter plate body 11; two connecting plates 12 are symmetrically welded and fixedly connected to the side walls of the filter plate body 11 at both ends; and a plurality of connecting holes 13 are evenly spaced on the connecting plate 12.

[0046] A filter head 15 is installed in the socket 14, and a clamping member is clamped between the filter head 15 and the socket 14. The clamping member includes: a first clamping ring 22, a fixing block 23, a connecting ring 25, a second clamping ring 28, a cover ring 27, and an internal thread section 29. The first clamping ring 22 is made of rubber and is clamped in the socket 14 and has an interference fit with the socket 14. The inner side wall of the first clamping ring 22 is provided with a thread, and the outer wall of the filter head 15 is provided with an external thread. The inner side wall of the first clamping ring 22 is threadedly connected to the filter head 15. The fixing block 23 is provided with two and symmetrically fixedly connected to the top wall of the first clamping ring 22. The top wall of the first clamping ring 22 is provided with a first clamping groove 26. The connecting ring 25 is fixedly connected to the groove wall of the first clamping groove 26, and the outer side wall of the connecting ring 25 is provided with a clamping thread. Two symmetrical second retaining grooves 24 are provided on the top wall of the first retaining ring 22, the second retaining ring 28 is inserted into the first retaining groove 26, the cover ring 27 is fixedly connected to the top wall of the second retaining ring 28, and a plurality of internal thread sections 29 are fixedly connected to the inner side wall of the second retaining ring 28 at equal intervals. The internal thread sections 29 are threadedly connected to the outer side wall of the connecting ring 25.

[0047] Working or installation process:

[0048] Insert the first snap ring 22 into the insertion hole 14 from the bottom and make the first snap ring 22 and the insertion hole 14 interference fit, pass the tube part of the lower end of the filter head 15 through the cover ring 27, then insert the filter head 15 with the cover ring 27 from top to bottom (i.e., insert it from the top of the filter plate body 11 downward) into the first snap ring 22 and rotate the filter head 15 with the cover ring 27 so that the filter head 15 is threadedly connected with the inner wall of the first snap ring 22, insert the connecting ring 25 into the first groove 26 and rotate the connecting ring 25 and the cover ring 27. The rotation of the connecting ring 25 drives the internal thread section 29 to rotate, so that the internal thread section 29 is threadedly connected with the outer wall of the second snap ring 28. At this time, the bottom wall of the cover ring 27 contacts the top wall of the filter plate body 11;

[0049] After installing the filter head 15 in the first clamping ring 22 respectively, the bolts are passed through the connecting holes 13 so that the bolts are fixedly connected to the side beams and the middle filter beam in the filter tank. The four sides of the filter plate body 11 are placed on the side beams and the middle filter beam in the filter tank. The lower part of the gap in contact with the concrete pool is supported by the beam, and there is no seam in the rest of the part.

[0050] In summary, the high rigidity of the arc structure is utilized to withstand the bidirectional force acting on the filter plate. The upper flat surface provides good conditions for the installation of the filter head 15, and the upper convex groove formed by the upper plane and the downward edges of the arc structure on both sides facilitates the air circulation of the bottom wall of the filter plate, and also provides good conditions for the discharge of residual gas after the air flushing is completed. After the air flushing is completed, under the pressure of the flushing water, the residual gas accumulates in the upper convex groove, and is finally discharged through the gap between the filter head 15 and the two clips, thereby avoiding air blockage caused by the residual gas at the bottom of the filter tank.

[0051] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
