[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figure 1 - Figure 4This utility model provides a technical solution: a novel filter brick for deep bed filter tanks, comprising a filter brick body 1, with an arc-shaped installation groove 2 at the bottom of the filter brick body 1. The filter brick body 1 and the arc-shaped installation groove 2 form a pipe corridor for pipe installation. The arc-shaped installation groove 2 is a semi-circle that increases aeration channels to make aeration more evenly distributed. The arc-shaped installation groove 2 facilitates the laying and installation of bottom pipes, forms a pipe corridor, and increases aeration channels to make aeration more evenly distributed. The structure is symmetrical, improving functionality while saving materials and reducing costs. In conjunction with symmetrically distributed brick columns 4, it increases the installation stability and strength of the filter brick body 1. Multiple brick columns 4 are evenly arranged along the length of the bottom of the filter brick body 1, and the brick columns 4 form two rows at the bottom of the filter brick body 1, symmetrically distributed. The brick columns 4 are tapered structures with gradually decreasing size from top to bottom, and the lower ends of the brick columns 4 become pointed and multiple are symmetrically distributed, which facilitates the lower ends of the brick columns 4 to be embedded into the installation ground, increasing the installation strength and stability of the entire filter brick body 1.

[0021] In this embodiment, preferably, the filter brick body 1 and the brick column 4 are integrally formed and hollow brick structures. The hollow structure reduces the weight of the filter brick body 1 and facilitates the filling of heavier brick materials. The upper end of the filter brick body 1 is provided with an inward chamfer 12. The chamfer 12 is chamfered inward so that the edge of the filter brick body 1 will not bulge and cause injury.

[0022] In this embodiment, preferably, a rectangular notch 11 is provided on the upper surface of the filter brick body 1 to facilitate the placement of bricks, stones, etc. inside the filter brick body 1. The bottom of the filter brick body 1 is arched upward to fit the arc-shaped installation groove 2, which facilitates pipe installation. In addition, multiple reinforcing beams 10 are evenly arranged between the arched bottom of the filter brick body 1 and the side wall to increase the overall installation strength of the filter brick body 1 and prevent deformation.

[0023] In this embodiment, preferably, two right-side positioning blocks 5 are provided on the right side of the filter brick body 1, and two left-side positioning blocks 8 are provided on the left side of the filter brick body 1, corresponding to the positions of the right-side positioning blocks 5. The arrangement of the left-side positioning blocks 8 and the right-side positioning blocks 5 can play an alignment and positioning role when two adjacent filter brick bodies 1 are horizontally spliced.

[0024] In this embodiment, preferably, two right-side inserts 6 are provided on the right side of the upper chamfer 12. Each right-side insert 6 is composed of two outwardly inclined wedges, with an inverted "V" shape formed between the two wedges. A left-side locking block 7 corresponding to the position of the right-side insert 6 is provided on the left side of the upper chamfer 12. The left-side locking block 7 is V-shaped and can engage with the right-side insert 6, so that two adjacent filter bricks 1 can be spliced ​​vertically without detaching outward, thereby increasing the assembly strength of the filter bricks 1.

[0025] In this embodiment, preferably, the front surface of the filter brick body 1 is provided with two front protrusions 3, and a rectangular space is left between the two front protrusions 3. The rear surface of the filter brick body 1 is provided with a rear protrusion 9 corresponding to the position of the rectangular space. The rear protrusion 9 is engaged with the rectangular space between the two front protrusions 3, so that when the two filter brick bodies 1 are spliced ​​together, they can play a role in engagement and positioning.
