Problems solved by technology

However, when prefabricated filter plates are assembled, it is difficult to control the flatness of the bottom of the plate during assembly, and the seams of adjacent filter plates need to be treated. The existing problems of the current treatment process are that the joints are prone to air leakage and the seam height difference is large. question

Embodiment 1

[0022] The fast packing filter plate of embodiment 1, as Figure 1-Figure 3 As shown, it includes a square concrete slab body 1, steel skeleton 2 and several embedded parts 3, several embedded parts 3 are used to install long handle filter heads (not shown in the figure), steel skeleton 2 and several embedded parts 3 They are respectively arranged in the concrete slab body 1, and the side edges of the reinforcement skeleton 2 are exposed on the four sides of the concrete slab body 1, and each side of the concrete slab body 1 is a slope 11 inclined from top to bottom to the outside.

[0023] In Embodiment 1, the reinforcement frame 2 is a reinforcement cage formed by binding several reinforcement bars 21 criss-crossing horizontally and vertically. Iron wires (not shown in the figure) are bound at the intersections of the horizontal and vertical reinforcement bars 21. The side edges of the reinforcement frame 2 include A plurality of arc-shaped sections 22 arranged at intervals,...

Embodiment 2

[0026] The quick packing filter plate of embodiment 2, the difference with embodiment 1 is, in embodiment 2, as Figure 4-Figure 5 As shown, no tenons and tenons are designed on the concrete slab body 1 . When splicing the quick-installed filter plates of Example 2 on site, after lining the bottom of each concrete plate body 1 with a mold (not shown in the figure), first make the exposed steel bars of the adjacent two concrete plate bodies 1 The side edges of the skeleton 2 are staggered and stuck, and then concrete mortar is poured at the joints of two adjacent concrete slab bodies 1 .

Embodiment 3

[0027] The fast packing filter plate of embodiment 3, the difference with embodiment 2 is, in embodiment 3, such as Figure 6-Figure 9 As shown, the side edge of the concrete slab body 1 is not provided with grooves. The splicing method of the quick-pack filter plate in Example 3 is the same as that of the quick-pack filter plate in Example 2.

[0028] In practical application, taking a square concrete slab as an example, its structure can be steel bars exposed on four sides, as in Example 3; it can also be steel bars exposed on three sides, which is more common in the case of connecting with filter tank beams. The surface that does not expose the steel bar just rides on the beam and fixes; it can also be that the steel bar is exposed on both sides, as in Embodiment 1. It depends on the actual situation.

Abstract

The invention discloses a fast-assembly filter plate. The fast-assembly filter plate comprises a concrete plate body, a steel reinforcement framework and a plurality of embedded parts, wherein the steel reinforcement framework and the embedded parts are arranged in the concrete plate body, the side edges of the steel reinforcement framework are exposed out of a plurality of side faces of the concrete plate body, and each side face of the concrete plate body is an inclined face inclining outwards from top to bottom. When the fast-assembly filter plate is spliced on site, after the bottom of each concrete plate body is lined with a mold sheet, the side edges of the exposed steel bar frameworks of the two adjacent concrete plate bodies are clamped in a staggered manner, and then concrete mortar is poured at the joint of the two adjacent concrete plate bodies, so that the splicing flatness and firmness of each concrete plate body are ensured, and the slurry leakage phenomenon is effectively avoided. Due to the fact that each side face of each concrete plate body is the inclined face inclining towards the outer side from top to bottom, a joint between every two adjacent concrete plate bodies is of a big-end-up funnel structure, rapid grouting is facilitated, the upper surface area of the joints is increased, and the overall strength and flatness of the multiple filter plates after grouting are guaranteed.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a quick-install filter plate. Background technique [0002] The filter plate is a key device in the water treatment process, and it plays a dual role in the filter tank for carrying the filter layer, filtering and backwashing water distribution (air). The quality of the filter plate, including the flatness and precision of the filter plate, is directly related to the long-term benefits of the filtered water quality, water quantity and operation of the water plant and sewage plant. [0003] There are roughly three ways to make traditional filter plates: integral pouring filter plates, prefabricated filter plates and stainless steel filter plates. Among them, the cost of prefabricated filter plate is the lowest, and the installation is relatively simpler. However, when prefabricated filter plates are assembled, it is difficult to control the flatness of the bottom of the plate duri...
