Specific embodiments
[0025] To further understand the content, features and effects of the present utility model, the following embodiments are given and are described in detail in conjunction with the attached Figures 1 to 6 as follows.
[0026] As Figures 1 to 6 shown, this embodiment provides a filtering device for building water supply and drainage, including a filter box 1. An inlet water pipe 2 is arranged on the upper part of the filter box 1, and an outlet water pipe 3 is arranged on the lower part of the filter box 1. The inner bottom surface of the filter box 1 is inclined towards the side of the outlet water pipe 3, which is convenient for timely discharging the filtered water;
[0027] Three groups of slots 4 are fixedly connected to the inner wall of the filter box 1 by welding. Each group of slots 4 includes two pieces, which are respectively arranged on the left and right inner walls of the filter box 1. Filter plates 5 inclined towards the same side are slidably inserted into each group of slots 4, which is convenient for timely replacement later. Above the relatively lower end of each single filter plate 5, there is a discharge mechanism 6 for discharging impurities, and below the discharge mechanism 6, there is a collection mechanism 7 for collecting the impurities flowing out from the discharge mechanism 6. A detachable cover plate 8 is arranged on the side of the filter box 1. The filter box 1 is a square structure with an opening on the side. This cover plate 8 is used to limit the side ends of the three filter plates 5. The cover plate 8 is detachably connected to the filter box 1 by four bolts. A sealing ring is arranged between the cover plate 8 and the filter box 1 to prevent water from flowing out through the gap between the cover plate 8 and the filter box 1, which is convenient for timely cleaning of the filter plates 5. The impurities finally reaching the collection mechanism 7 in the present utility model include sediment, suspended solids and algae, etc. The types of impurities passing through the filter plates 5 are similar to them, but their particle sizes are smaller. In addition, the discharge mechanism 6 is arranged above the slots 4, so as to avoid a large amount of sewage flowing directly from the discharge mechanism 6, resulting in a decrease in the amount of sewage passing through the filter plates 5.
[0028] The utility model is provided with a slot, a plurality of filter plates matched therewith, a detachable cover plate, and a discharging mechanism and a collecting mechanism respectively used for discharging and collecting impurities, which facilitates the timely removal of impurities. By timely opening the cover plate, taking out and cleaning the filter plates, it is avoided that during the working process, due to the blockage of the filter plates by impurities, the amount of water passing through the filter plates will become less and less, and more water is discharged to the collecting mechanism through the discharging mechanism.
[0029] In this embodiment, as Figure 1 shown, the above-mentioned water inlet pipe 2 and water outlet pipe 3 are arranged on the same side wall of the filter tank 1, and the above-mentioned collecting mechanism 7 is arranged on the side wall opposite to the above-mentioned water outlet pipe 3. Such an arrangement is more reasonable, avoiding interference caused by the water outlet pipe 3 and the collecting mechanism 7 being arranged on the same side of the filter tank 1.
[0030] In this embodiment, as Figure 2 、 4 and 5 shown, the above-mentioned discharging mechanism 6 includes a waste discharging hole 61, a rotating shaft 62, a rotating plate 63 and a guide plate 64. The above-mentioned discharging mechanism 6 is a total of three groups with the same size, which are arranged in sequence from top to bottom along the side wall. Among them, the above-mentioned waste discharging hole 61 is opened on the side wall of the filter tank 1, and it is the same side wall corresponding to the above-mentioned collecting mechanism 7. The above-mentioned rotating shaft 62 is arranged in the front and rear side walls above the waste discharging hole 61. The above-mentioned rotating plate 63 is hinged on the rotating shaft 62, so that under the impact of water flow and impurities, by pushing open the rotating plate 63, the impurities and water flow flow into the lower collecting mechanism 7 along the guide plate 64 together. The above-mentioned guide plate 64 is fixedly inclined and arranged on the side wall at the lower end of the waste discharging hole 61. When the impact of water flow and impurities stops, the rotating plate 63 returns to the position coplanar with the side wall of the filter tank 1 under the action of gravity. At this time, the rotating plate 63 can be used to block external dust and other impurities from entering the interior of the filter tank 1.
[0031] In this embodiment, as Figures 2 to 6As shown in the figure, the above-mentioned collection mechanism 7 is detachably arranged at the lower end of the side wall of the filtering box (1). It includes a collection box 71, a clamping plate 72, a placement plate 73 and a locking part 74. The distance between the clamping plate 72 and the filtering box 1 is just enough to accommodate the above-mentioned collection box 71. The above-mentioned placement plate 73 is fixedly arranged on the side wall of the filtering box 1 by welding. The above-mentioned collection box 71 is placed above the placement plate 73. The inner side surface of the above-mentioned collection box 71 abuts against the side wall of the filtering box 1. The collection box 71 is a square structure with an opening at the upper end as a whole. The cross-section of the clamping plate 72 is U-shaped, and the inner surface of the clamping plate 72 fits with the outer surface of the collection box 71. The above-mentioned clamping plate 72 is slidably clamped outside the above-mentioned collection box 71. The above-mentioned collection mechanism 7 can also be only a collection box, which is fixedly arranged at the lower end of the side wall of the above-mentioned filtering box 1 by welding. The sewage inside it is discharged through the drain hole at the bottom, and the impurities inside are cleaned manually.
[0032] In this embodiment, as Figure 3 shown, the above-mentioned locking part 74 includes a locking strip 741 and a threaded rod 742 that cooperate with each other. The above-mentioned threaded rod 742 is used to fix the collection box 71 and the clamping plate 72 together in the placement plate 73. The upper end of the above-mentioned locking strip 741 is fixedly arranged at the lower end of the clamping plate 72 by welding. The lower end of the above-mentioned locking strip 741 penetrates through the above-mentioned placement plate 73. A first threaded hole for the above-mentioned threaded rod 742 to pass through is opened on the above-mentioned locking strip 741. A second threaded hole that cooperates with the above-mentioned threaded rod 742 is arranged on the above-mentioned placement plate 73. The first threaded hole and the second threaded hole are concentrically arranged. When there is too much water and impurities in the collection box 71, when the threaded rod 742 is screwed out of the first threaded hole, the clamping plate 72 and the collection box 71 can be taken out in sequence, the water and impurities inside the collection box 71 can be cleaned in time, and an empty collection box 71 can be replaced in time.
[0033] In this embodiment, as Figure 3 shown, two downwardly protruding guide strips 721 are arranged at the lower end of the above-mentioned clamping plate 72. Through holes for the above-mentioned guide strips 721 to pass through are arranged on the above-mentioned placement plate 73. By arranging the guide strips 721, a guiding effect is achieved, making the up and down movement process of the clamping plate 72 relative to the placement plate 73 more stable.
[0034] In this embodiment, as Figure 4 shown, four support legs 11 are fixedly connected to the bottom of the above-mentioned filtering box 1, which is convenient for supporting the entire filtering device.
[0035] In this embodiment, as Figure 2 shown, the number of the above-mentioned filter plates 5 is three. A plurality of round holes 51 with the same size are opened on each single above-mentioned filter plate 5. The diameters of the round holes 51 on the three above-mentioned filter plates 5 decrease sequentially from top to bottom. By setting triple filtration, the final filtration accuracy is higher.
[0036] In this embodiment, as Figure 1 shown, an observation window 81 is provided on the cover plate 8, which is convenient for observing the internal filter plate 5.
[0037] The above-mentioned utility model only expresses the implementation manners of the embodiments of the present utility model, and thus cannot be construed as a limitation on the scope of the utility model patent, nor is it a limitation on the structure of the embodiments of the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the embodiments of the present utility model, several changes and improvements can still be made, and these all belong to the protection scope of the embodiments of the present utility model.
