Description

Technical Field

[0001] The utility model belongs to the field of filtering devices, in particular to an activated carbon filter. Background Art

[0002] Activated carbon is a porous material with high adsorption properties. When water flows through the activated carbon filter media, pollutant molecules are adsorbed on its surface and react chemically with the activated carbon, achieving the purification effect.

[0003] Activated carbon filter plates are typically installed inside the tank, filtering the water as it passes through. However, activated carbon has a limited lifespan: after a period of time, its adsorption capacity for pollutants reaches saturation, requiring removal and replacement. However, the internal structure of the tank restricts this removal process.

[0004] To address this issue, Chinese patent application CN216191220U proposes an activated carbon filter, which packs activated carbon into the inner cylinder wall. Once the upper end cap is opened, the inner cylinder can be hoisted using a lifting ring and external device to refill the activated carbon. However, the upper end cap and the outer tank body are connected by numerous bolts, and removing these bolts to open the upper end cap is time-consuming. Furthermore, since the activated carbon is packed into the inner cylinder wall, the water does not flow through the activated carbon, rendering it ineffective for filtration. Utility Model Content

[0008] Furthermore, the rotating mechanism includes a gear steering device installed on the top end of the corresponding bracket, the longitudinal axis of the gear steering device is connected to the bottom end of the screw rod, and a hand wheel is connected to the transverse axis of the gear steering device.

[0012] Technical effect: In the present invention, under the action of the driving mechanism, the ear plate can be driven to slide along the slide groove, so that the ear plate drives the tank cover to be lifted and lowered. On this basis, since the tank cover and the filter plate structure are connected by a connecting rod, when the tank cover is lifted and lowered, the filter plate structure will also be lifted and lowered. In this way, the filter plate structure can be taken out of the tank body, and the barrel cover and the barrel-shaped part in the filter plate structure are detachable, so the activated carbon bag in the barrel-shaped part can be easily replaced. In addition, the tank cover and the ear plate are connected here, and the two are driven to lift and lower by the driving mechanism.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] The activated carbon filter provided in this embodiment is as follows Figure 1 and Figure 2 As shown, it includes a middle member and side members, wherein:

[0021] The middle component includes a bottom plate 1, with a tank body 2 mounted on the top of the bottom plate 1 via a bracket. The bottom of the tank body 2 is connected to a water outlet pipe 3, the outer side of the tank body 2 is connected to a water inlet pipe 4 near the top, and a tank cover 5 is provided on the top. In addition, a barrel-shaped part 6 with a diameter equal to its inner diameter is provided inside the tank body 2. The inside of the barrel-shaped part 6 is used to place the activated carbon bag, and an openable barrel cover 7 is provided on the top of the barrel body 2. A plurality of through holes 8 are provided between the two, so that the two and the activated carbon bag placed therein together form a filter plate structure. A connecting rod 9 is fixedly connected between the filter plate structure and the bottom end of the tank cover 5. Specifically, if Figure 4 As shown, the connecting rod 9 movably passes through the middle of the barrel cover 7, and its bottom end is fixedly connected to the inner bottom end of the barrel-shaped member 6.

[0022] The side member includes a bracket 10 symmetrically mounted on the top of the bottom plate 1, the top of the bracket 10 is connected to the vertical plate 11, the vertical plate 11 is provided with a longitudinal slide 12, the slide 12 is vertically engaged and slidably connected with an ear plate 13, the outer end of the ear plate 13 is fixed to the side of the tank cover 5; In addition, the bottom plate 1 is also provided with a driving mechanism 14 for driving the ear plate 13 to slide along the slide 12, as shown in FIG. Figure 3As shown, the driving mechanism 14 includes a screw rod 1401 that is threadedly connected to one of the ear plates 13 and is longitudinally connected. The top of the screw rod 1401 is connected to the top of one of the slide grooves 12 through a bearing, and a rotating mechanism 1402 is provided at its bottom end for driving its rotation. The rotating mechanism 1402 includes a gear steering device 140201 installed at the top of the corresponding bracket 10. The longitudinal axis of the gear steering device 140201 is connected to the bottom end of the screw rod 1401, and a hand wheel 14 is connected to its transverse axis. To facilitate rotation, handwheel 140202 can be replaced with a servo motor and coupling combination.
