DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS [0025] Preferred embodiments of the present invention will now be described with reference to the figures.
[0026] As shown in Figs. 2 and 3, a filter module 1 for containment recycling filters includes a collector groove 11, a plurality of filter cylinders 12, two grilles 13, a plurality of connecting member 14 and two bases 15.
[0027] As shown in Fig. 4, the collector groove 11 is shaped as a case that is provided with two opening at ends, and the collector groove 11 includes two side walls 111 that are opposite to each other, as well as a top wall 112 and a bottom wall 113 that are opposite to each other; the top wall 112 is connected between two upper ends of the side walls 111, the bottom wall 103 is connected between two lower ends of the side walls 111. Two flange parts 114 extended outwards relative to the top wall 112, the bottom wall 113 and the side walls 111 are configured at two ends of the collector groove 11, which is used for connecting with other collector grooves or connecting modules 1 of the filter. Preferably, engaging members 115 are formed on the flange parts 114 to achieve the connections.
[0028] Two rows of bolts 112a are alternately protruded from the top wall 112, closed to the side walls 111 respectively and parallel to a length direction of the side walls 111, further, the two rows of bolts 112 are symmetrical. In the present embodiment, each row has four bolts. Two base plates 116 are connected with two ends of the bottom wall 113 and pressed against the flange parts 114.
Two ends of each base plate 116 is protruded out of the side wads 111 and is with a through hole 116a.
The two side walls 111 are arranged symmetrically, and each of which is provided with a plurality of filter cylinder holes 111a. That is, each filter cylinder hole Ilia at one side wall 111 is aligned with the correspondingfilter cylinder hole Ilia at the other side wall 111, Preferably, the filter cylinder holes 111 a are arranged in an array, for example, three rows and four columns (12) filter cylinder holes 111a are arranged at each side wall 111, and each filter cylinder hole 111a is hexagonal. Four bolts 111b are formed around the each filter cylinder hole Ilia. Referring to Fig. 3, for enhancing the strength of the collector groove 11, several rails 117 are configured between the two side walls 111, and two ends of each rail 117 is fixed to the inner surfaces of the side wall 111 to prevent the deformation of the side walls 111.
[0030] Referring to Figs. 2, 4, 5, the filter cylinders 12 are respectively inserted in the filter cylinder holes Ilia, and thus the quantity of the filter cylinders 12 is 24. Specifically, each filter cylinder 12 is a hexagonal prism, a connecting plate 121 this id rectangular is provided at its end, and four through holes 121a are configured at the four corners. When the filter cylinders 12 are installed, the filter cylinder 12 is aligned with the filter cylinder hole Ilia, with the connecting plate 121 is pressed against the side wall 111, causing the bolts 11 lb around the filter cylinder hole 11 la to pass through the through holes 121a on the connecting plate 121, and the filter cylinder 12 can be fixed to the side wall 111 after nuts are engaged with the bolts 111b.
] For increasing filtering area and improving filtering efficiency, the cylinders 12 in this embodiment are double-layer screen structures.
cylinder 12 include an outer filter net 122 and an inner filter net 123 which is configured inside the outer filter net 122, with spacing, both of which are in prismatic shape. As shown, a hexagonal circular space 124 is formed between the outer and the inner filter nets 122, 123. Both of the outer and the inner filter nets 122, 123 are provided with two end openings, and the connecting plate 121 is located outside the outer filter net 122 and extended outwards. Further, the filter cylinder 12 includes a front cover plate 125 and a rear cover plate 126, the front cover plate 125 is a hexagonal ring, and the rear cover plate 126 is hexagonal corresponding to the opening. More specifically, the front cover plate 125 is fixed on the front end and seals the opening of the hexagonal circular space 124, while the rear cover plate 126 is fixed on the rear end and seals the rear opening of the inner filter net 123, but doesn’t seal the hexagonal circular opening 124. After the filter cylinder 12 is mounted on the collector groove 11, the hexagonal circular space 124 is communicated with the inner space of the collector groove 11, and the filtering fluid will enter the hexagonal circular space 124 via the outer filter net 122, and then go into the collector groove 11 after filtering.
[0032] Referring to Figs. 6 and 4, two bolts 151 are arranged on two ends of the base 15, with the same spacing with that through holes 116a on the base plate 116, which is for supporting the collector groove 11 to make it fix on the ground of the sump stably. During the filter module 1 is mounting, the two bases 15 are welded to the ground of the sump firstly, then the collector groove 11 is disposed on the bases 15 to cause the bolts 151 to insert in the through ole 116a, finally nuts are screwed on the bolts 151 to finish the installation of the collector groove 11. As a preferable manner, the through holes 116a on the base plate 116 can be rectangular, so that the bolts 151 can slide along the through holes 116a to fine adjust the position of the collector groove 11.
[0033] Referring to Figs. 7 and 2, the two grilles 13 are grid structures, one end of each grille 13 is provided with a row of through holes (not shown), such as four through holes are corresponding to the bolts 112a on the top wall 112. The connecting members 14 are used for connecting with the bolts 112a on the top wall 112 so as to fix the grilles 13 on the collector groove 11, thus the quantity of the connecting members 14 is four as well. Specifically, the connecting members 14 are in strip structures, with through holes 141 are formed on ends thereof. After the collector groove 11 are installed, the ends of the grilles 13 where the through holes are formed are mounted on the top wall 112, causing the bolts 112a to engage with the through holes of the grilles 13, then the connecting members 14 presses against the grilles 13 with the through holes 141 of each connecting member 14 engages with the bolts 112a; finally, the bolts 112a are screwed by nuts to finish the positioning of the grilles 13 on the collector groove 11. After the grilles 13 are positioned, they are covered above the filter cylinders 12 on the side walls. Since only one end of the grille 13 is fixed, thus a support rod 16 is fixed on its suspending end and extended downwards to reach the ground, so as to enhance the grilles 13. Preferably, the grilles 13 are formed by intersecting longitudinal members with transverse members, for example, the longitudinal members are flat steels with size of 30mm 5mm, and the transverse members are twist steels, and the grille unit is with size of 100mmx30mm.
The bolts in this embodiment can be molded directly, or thread through a hole on the corresponding position to form.
[0035] In comparison with the prior arts, since the filter cylinder holes Ilia are provided on the two side walls 111 of the collector groove II in the filter module 1 of a containment recvcling filter, thus the collector groove 11 is a symmetrical structure, which is easily processed and formed. Further, the plurality of filter cylinders 12 are configured on both side walls 111, thus the torques generated by the filter cylinders 12 on the collector groove 11 are counteracted each other, so that the filter module 1 is more stable, and no additional support component is required to support the collector groove 11, thereby the installation of the filter module 1 is more simpler.
[0036] While the invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
