Description

A filter bed activated carbon interception device Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to an activated carbon interception device for filter beds. Background Technology

[0002] Activated carbon particles have a low density and tend to float with the water flow during backwashing, eventually leading to particle loss. Some filter beds have vertically added interception nets of a certain mesh size using expansion screws, but these nets also intercept surface foam, affecting the backwashing effect. In addition, after backwashing, carbon particles tend to stick to the interception nets, requiring manual rinsing with water pipes to remove the adhering particles.

[0003] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This utility model provides an activated carbon interception device for a filter bed, as shown in Figures 1 to 3, which is composed of several interception components 10 connected in sequence. Each interception component 10 includes a telescopic support rod 100, with a pair of filter screen mechanisms 200 symmetrically arranged at both ends of the support rod 100. Each filter screen mechanism 200 includes a fixed frame 201 and a filter screen 202 disposed on the fixed frame 201. The fixed frame 201 is mounted on an inverted V-shaped support plate 300, which is disposed on a V-shaped filter bed 20. The fixed frame 201 includes a first mounting plate 211 and a filter frame 221 disposed at the long end of the first mounting plate 211. A locking plate 231 is disposed at the long end of the filter frame 221 and is mounted on the support rod 100. Multiple reinforcing plates 241, which are triangular plates, are disposed between the first mounting plate 211 and the filter frame 221. The fixed frame 201 is integrally formed, and the filter screen 202 is welded to the fixed frame 201.

[0032] The retractable support rod 100 allows for flexible installation and disassembly without fixed mounting. This application effectively intercepts carbon particles floating during backwashing of activated carbon filters, preventing carbon particle loss. It is suitable for intercepting and recovering activated carbon particles during the backwashing process of activated carbon filters, preventing filter media loss and reducing the pressure and cost of subsequent processing.

[0033] In specific implementation, the first mounting plate 211 is provided with a plurality of first waist-shaped holes 251.

[0034] In specific implementation, as shown in Figure 3, the inverted V-shaped support plate 300 is integrally stamped and bent from a second mounting plate 301 and a fixing plate 302. The fixing plate 302 is integrally extended and bent from the long end of the second mounting plate 301. The included angle between the second mounting plate 301 and the fixing plate 302 is an acute angle. The second mounting plate 301 is provided with multiple fastening bolts 303. These fastening bolts 303 pass through the first oblong hole 251 and, through nuts, fix the first mounting plate 211 to the second mounting plate 301. Three fastening bolts 303 are provided.

[0035] In specific implementation, as shown in Figure 4, the support rod 100 includes a fixed rod 101. One end of the fixed rod 101 is provided as a horizontal boss, and the other end of the fixed rod 101 is fitted with a sliding rod 102. After the sliding rod 102 slides to the top surface of the horizontal boss, the other end face of the sliding rod 102 is flush with the end face of the fixed rod 101. The sliding rod 102 is provided with a plurality of second waist-shaped holes 103. After adjusting the position of the sliding rod 102 on the fixed rod 101, it is fixed by passing a first bolt 104 through the second waist-shaped holes 103.

[0036] By adjusting the length of the support rod 100 to press against the filter screen mechanism 200 on both sides, a self-locking structure is formed, which enhances the overall rigidity. During backwashing, the water flow impact causes slight deformation of the pool wall. Adjusting the length of the support rod 100 can automatically fine-tune the length to maintain the tight fit between the filter screen mechanism 200 and the pool wall, avoiding gaps caused by pressure fluctuations.

[0037] In practice, both the fixed rod 101 and the sliding rod 102 are connected to the locking plate 231 by the second bolt 105.

[0038] In practice, the support rod 100 is made of stainless steel, and the fixing frame 201 and the inverted V-shaped support plate 300 are also made of stainless steel.

[0039] In practice, the angle formed between the first mounting plate 211 and the filter frame 221 is an acute angle.

[0040] In summary, this utility model discloses an activated carbon interception device for filter beds, which is suitable for intercepting and recovering activated carbon particles during the backwashing process of activated carbon filter beds, effectively preventing filter media loss and reducing the pressure and cost of subsequent process treatments.
