Activated carbon filter media and its manufacturing method

Abstract

An activated carbon filter material and its manufacturing method are disclosed. The method involves a conveying device sequentially conveying a first filter material body through a feeding device and a welding device, and the conveying device conveying a second filter material body spaced above the first filter material body through the welding device. Then, the feeding device spaced multiple activated carbon stacks on the top surface of the first filter material body. Next, the welding device drives the first and second filter material bodies to partially fuse together, thereby defining multiple accommodating spaces for each of the activated carbon stacks. This manufacturing method allows the produced activated carbon filter material to maintain a high porosity while simultaneously having uniformly and stably distributed activated carbon particles, thus significantly improving the quality of the activated carbon filter material.

2. The activated carbon filter material as described in claim 1, wherein, These containment spaces are spaced apart from each other.

3. The activated carbon filter material as described in claim 2, wherein, The diameter of each of these accommodating spaces is between 3 and 10 mm.

4. A method for manufacturing activated carbon filter material, comprising the following steps: a conveying step, wherein a conveying device sequentially conveys a first filter material body through a feeding device and a welding device, and a second filter material body is conveyed through the welding device at intervals above the first filter material body; a feeding step, wherein the feeding device places a plurality of activated carbon piles at intervals on the top surface of the first filter material body, each activated carbon pile having a plurality of activated carbon particles; and a pressing step, wherein the welding device presses the first filter material body and the second filter material body together vertically, thereby partially fusing the first filter material body and the second filter material body together, thereby defining a plurality of accommodating spaces that respectively surround and accommodate the activated carbon piles.

5. The method for manufacturing activated carbon filter material as described in claim 4, wherein, The first filter material body and the second filter material body, which are fused together, will cooperate with the activated carbon piles they cover to form an activated carbon filter material. In the conveying step, the conveying device conveys the first filter material body, the second filter material body and the activated carbon filter material through a roll-to-roll conveying method.

6. The method for manufacturing activated carbon filter material as described in claim 4, wherein, In this pressing step, the fusion device drives the first filter material body and the second filter material body to fuse together and define a plurality of annular fusion portions that respectively enclose the respective accommodating spaces.

7. The method for manufacturing activated carbon filter material as described in claim 6, wherein, These fusion joints are spaced apart from each other.

8. A method for manufacturing activated carbon filter material as described in claim 4, wherein, In the conveying step, the conveying device intermittently conveys the first filter material body and the second filter material body. In the feeding step, the feeding device places the activated carbon piles on the first filter material body during the period when the conveying device stops conveying the first filter material body. In the pressing step, the welding device presses and welds the first filter material body and the second filter material body together from top to bottom during the period when the conveying device stops conveying the first filter material body.

9. A method for manufacturing activated carbon filter material as described in claim 8, wherein, In this conveying step, the conveying device operates at a speed of 1 m / min for 5 seconds to convey the first filter material body and the second filter material body, and then stops for 3 seconds, intermittently conveying the first filter material body and the second filter material body. The fusion device uses ultrasonic heat fusion technology to drive the partial fusion of the first filter material body and the second filter material body.

10. A method for manufacturing activated carbon filter material as described in claim 4, wherein, The feeding device includes a trough containing the activated carbon particles, a distributing platform disposed below the trough and above the first filter material body, and a distributing unit. The distributing platform has multiple vertically penetrating distributing holes. In the feeding step, the trough releases a predetermined amount of the activated carbon particles onto the distributing platform, and the distributing unit pushes the activated carbon particles on the distributing platform through the distributing holes, causing the activated carbon particles to fall down onto the first filter material body through the distributing holes of the distributing platform, thereby forming the activated carbon piles.
