Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments given are not intended to limit the present utility model.

[0025] Embodiment 1

[0026] Referring to Figures 2 to 4 As shown, the present utility model provides a filter element pressing plate device, which includes a single pressing plate, and the single pressing plates are spliced to form a circular iron removal filter element pressing plate. Compared with the existing filter element pressing plates, the present utility model can reduce the number of parts, simplify the assembly process, and improve the disassembly and assembly efficiency.

[0027] Specifically, referring to Figure 1 As shown is the iron removal filter element pressing plate in the prior art. A total of 24 groups of filter elements are provided in the filter. The filter element pressing plate is integrally arranged as a circular plate 1. One group of filter elements is located at the center of the circular plate 1. Eight groups of filter elements are arranged around the center to form a first ring, and the remaining 15 groups of filter elements are arranged around the center to form a second ring. The second ring is concentric with the first ring and is located outside the first ring. After installation, each group of filter elements corresponds to a pressing plate, and a total of 24 groups of pressing plates are provided. The pressing plate is provided with a first mounting hole 2 for fixing the filter element and a second mounting hole 3 for fixing the fastener. In the existing filter element pressing plate structure, 3 to 4 groups of fasteners are provided on each pressing plate, and there are about 80 groups of fasteners in the whole filter element pressing plate; limited by the installation position, the diameter of each fastener is small and is prone to breakage, resulting in a huge workload for maintenance and replacement of the filter element. In a limited working space, there is a great operation risk and the operation efficiency is low.

[0028] Accordingly, in the first embodiment of the present utility model, there are at least three sets of the pressing plate monomers. At least two sets of first mounting holes 2 are penetratingly provided on each set of the pressing plate monomers. Each set of the pressing plate monomers is at least used for mounting two filter elements. The present utility model simplifies the disassembly and assembly steps through the integration of the pressing plate monomers, improving the processing efficiency. In the area other than the first mounting holes 2 on each set of the pressing plate monomers, second mounting holes 3 are also penetratingly provided. The second mounting holes 3 are used for passing through fasteners. Preferably, the fasteners are set as fastening bolts. After controlling the number of the pressing plate monomers, the number of the fasteners is less than that in the prior art, which is convenient for replacement, disassembly and assembly. The present utility model can also weaken the limitation of the installation space on the fasteners. The aperture of the second mounting holes 3 is larger than that in the prior art, and the diameter of the fasteners increases, with higher strength, making the service life of the filter element pressing plate longer.

[0029] Specifically, in the first embodiment of the present utility model, there are three sets of the pressing plate monomers. The pressing plate monomers include a first pressing plate 11, a second pressing plate 12 and a third pressing plate 13. The first pressing plate 11, the second pressing plate 12 and the third pressing plate 13 can be spliced with each other to form a circular plate 1. The side edges where the pressing plate monomers are in contact form a cutting part. Preferably, the first pressing plate 11, the second pressing plate 12 and the third pressing plate 13 are all set as integrally formed structures. The material of the filter element pressing plate is set as stainless steel. After the filter element pressing plate is integrally processed and formed, it is cut along the cutting part into the first pressing plate 11, the second pressing plate 12 and the third pressing plate 13.

[0030] It should be noted that the filter element pressing plate needs to be installed through a manhole. When the number of the pressing plate monomers is too large, the number of the second mounting holes 3 and the number of the fasteners used to fix the pressing plate monomers are both large, resulting in cumbersome installation and low efficiency, and affecting the size of the fasteners, which is likely to cause the bolts to be too thin and break. When the number of the pressing plate monomers is too small, the size of each set of the pressing plate monomers is too large to pass through the manhole and cannot be installed. In the preferred embodiment of the present utility model, the number of the pressing plate monomers is set as three sets. Each set of the pressing plate monomers is preferably provided with four sets of fasteners. The fasteners are preferably set as M16 bolts. In other embodiments, the number of the pressing plate monomers can be set according to actual needs, and is not limited thereto.

[0031] Specifically, referring to Figure 2 and Figure 4 as shown, the cutting part includes a first cutting part 41 and a second cutting part 42. The first cutting part 41 is the side edge where the first pressing plate 11 and the second pressing plate 12 are in contact. The second cutting part 42 is set as the side edge where the second pressing plate 12 and the third pressing plate 13 are in contact. In the first embodiment of the present utility model, the first cutting part 41 and the second cutting part 42 are arranged in sequence along the radial direction of the circular plate 1. In some embodiments, referring toFigure 4 As shown, the straight lines where the first cutting portion 41 and the second cutting portion 42 are located intersect; in some other embodiments, referring to Figure 2 As shown, the first cutting portion 41 and the second cutting portion 42 are arranged in parallel with each other.

[0032] Furthermore, in some embodiments, when the first cutting portion 41 and the second cutting portion 42 are perpendicular to the same diameter of the circular plate 1, the first cutting portion 41 and the second cutting portion 42 can trisect the diameter, so that the sizes of the first pressing plate 11, the second pressing plate 12 and the third pressing plate 13 are similar, which is convenient for installation through the manhole and avoids the size of a single pressing plate being too large or too small.

[0033] Continuing, in some embodiments, referring to Figure 2 and Figure 3 As shown, the first cutting portion 41 and the second cutting portion 42 are parallel to each other and both perpendicular to the same diameter, and the first cutting portion 41 and the second cutting portion 42 are symmetrically arranged on both sides of the center of the circular plate 1. The distance between the first cutting portion 41 and the second cutting portion 42 in the extending direction of the diameter is L1, that is, the width of the second pressing plate 12 in the radial direction of this diameter line is L1. Since the first cutting portion 41 and the second cutting portion 42 are symmetrically arranged, the first pressing plate 11 and the third pressing plate 13 are also symmetrically arranged about the center of the circle. The maximum widths of the first pressing plate 11 and the third pressing plate 13 in the radial direction of this diameter line are L2 and L3 respectively, and the diameter of the circular plate 1 is d; when the first mounting holes 2 on the first ring and the second ring are evenly distributed, if the first cutting portion 41 and the second cutting portion 42 equally divide the diameter of the circular plate, they will pass through several groups of the first mounting holes 2 and are far from the center of the first mounting holes 2, resulting in uneven stress on the pressing plate monomers on both sides of the first mounting holes 2 in the radial direction and unable to achieve an ideal pressing effect. Preferably, it is provided that

[0034] d = L1 + L2 + L3;

[0035] L2 = L3

[0036] L1 / d = 0.288.

[0037] When d is 1040 mm, L1 is set to 300 mm, and both L2 and L3 are set to 370 mm; by adjusting the ratio of L1, L2 and L3, the first cutting portion 41 and the second cutting portion 42 are closer to the center when passing through the first mounting holes 2, avoiding uneven stress on them and making the overall pressing effect of the filter element pressing plate better.

[0038] Furthermore, referring to Figure 2 andFigure 3 As shown, four sets of the second mounting holes 3 are provided on each of the first pressing plate 11, the second pressing plate 12, and the third pressing plate 13. The second mounting holes 3 are symmetrically arranged in pairs with respect to the diameter of the circular plate 1 on each pressing plate unit, and a pressing force is evenly applied to press the filter element.

[0039] Specifically, the first pressing plate 11, the second pressing plate 12, and the third pressing plate 13 are configured such that when they are spliced together, the two side surfaces in the thickness direction are flush, enabling uniform force application and forming a uniform pressing effect, ensuring that the filter element of the iron removal filter is evenly pressed and extending the service life of the device. Preferably, a chamfer is also provided on the cutting surface of the cutting portion to prevent operators from being cut.

[0040] Embodiment Two

[0041] Referring to Figure 5 As shown, Embodiment Two of the present utility model provides a filter element pressing plate device. The difference between the filter element pressing plate device in Embodiment Two and that in Embodiment One is only that the positions of the cutting portion and the pressing plate unit are different.

[0042] Specifically, in Embodiment Two, the cutting portion includes a third cutting portion 43, a fourth cutting portion 44, and a fifth cutting portion 45; the third cutting portion 43, the fourth cutting portion 44, and the fifth cutting portion 45 are all set to be the radius of the circular plate 1 and are arranged in sequence along the circumferential direction of the circular plate 1. Among them, the first pressing plate 11, the second pressing plate 12, and the third pressing plate 13 are all set to be fan-shaped structures. The third cutting portion 43 is used to separate the first pressing plate 11 and the second pressing plate 12, the fourth cutting portion 44 is used to separate the second pressing plate 12 and the third pressing plate 13, and the fifth cutting portion 45 is used to separate the first pressing plate 11 and the third pressing plate 13.

[0043] Furthermore, to balance the sizes of the first pressing plate 11, the second pressing plate 12, and the third pressing plate 13, the central angles between adjacent cutting portions are all 120°. In some implementation manners, to avoid the first mounting hole 2 or adjust the distance between the cutting portion and the center of the first mounting hole 2, the central angle can be adjusted according to actual requirements, and it is not limited thereto. It should be noted that when the cutting portion is arranged along the radius of the circular plate 1, the filter element provided at the center of the circular plate 1 is simultaneously pressed by at least three pressing plate units, and it is prone to uneven force; compared with the pressing plate units in Embodiment Two, the pressing plate units in Embodiment One have a better pressing effect on the filter element.

[0044] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
