Description

Technical Field

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

[0002] In the existing activated carbon filtration technology, the commonly used method is to fill the activated carbon directly into the filter. The disadvantage of this method is that the filter needs to be completely opened when replacing the activated carbon, which is not only complicated to operate, but also easy to cause waste of activated carbon and environmental pollution during the replacement process. In addition, since the activated carbon may shake or shift during the filtration process due to liquid flow or improper operation, the filtration effect may be unstable or even reduced. At the same time, in order to observe the internal conditions of the filter, it is usually necessary to open the equipment for inspection, which not only increases the complexity of the operation, but may also affect the normal operation of the equipment. In addition, for the daily cleaning and maintenance of the equipment, due to the complex structure of the equipment and the difficulty of operation, it is often difficult to achieve the expected cleaning and maintenance effects.

[0003] The above patent documents and prior art have the following technical problems:

[0004] 1. When replacing activated carbon, the activated carbon filter needs to completely open the equipment, which is complicated and time-consuming, and easily causes waste of activated carbon and environmental pollution;

[0005] 2. Traditional activated carbon filters usually require the device to be opened when observing the internal conditions of the device, which is complicated to operate and may affect the normal operation of the equipment. Utility Model Content

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-4 The activated carbon filter comprises a filter cylinder 2 and an elliptical head 5. An activated carbon box 3 is engaged inside the filter cylinder 2. Four groups of box handles 9 are distributed circumferentially inside the activated carbon box 3. A feed inlet 1 is provided on the side of the filter cylinder 2 near the bottom end. A discharge port 8 is provided on the top of the elliptical head 5. A sewage outlet 11 is provided in the vertical direction of the bottom surface of the filter cylinder 2. A mesh layer is provided on the outer wall of the activated carbon box 3. A limiting ring 12 is provided near the top surface of the inner wall of the filter cylinder 2. A positioning ring 13 is provided near the top of the outer wall of the activated carbon box. The positioning ring 13 is engaged with the limiting ring 12 in the vertical direction. The positioning ring 13 and the positioning ring 13 are mutually engaged. The design ensures the stability of the activated carbon box 3 in the filter cylinder 2 and prevents it from shaking or shifting. The activated carbon box 3 is arranged to be engaged inside the filter cylinder 2 for filtering. The entire filter is mainly used for filtering through the activated carbon box 3. The operator can easily take the activated carbon box 3 out of or put in the filter cylinder 2, which greatly improves the efficiency of replacing the activated carbon. At the same time, the positioning ring 13 at the top of the activated carbon box 3 and the limiting ring 12 on the inner wall of the filter cylinder 2 are engaged with each other, which ensures the stability of the activated carbon box 3 during the filtration process and prevents the filtration effect from being reduced due to shaking or shifting.

[0027] When the whole device is used for filtering, a guide port 14 is provided on the circumference of the bottom surface of the activated carbon box 3, and the vertical center line of the activated carbon box 3 coincides with the vertical center line of the filter cylinder 2. The bottom surface of the activated carbon box 3 is provided with a guide port 14, which is used to guide liquid or gas into the activated carbon layer for filtering. The vertical center line of the activated carbon box 3 coincides with the vertical center line of the filter cylinder 2 to ensure the uniformity of the filtering effect. The material enters the filter cylinder 2 through the feed port 1 on the side, and enters the inside of the activated carbon box 3 from the guide port 14 on the bottom surface of the activated carbon box 3 for filtering. The filtered material is discharged through the discharge port 8 on the top of the elliptical head 5 to purify the material. After filtering, the purified sewage is discharged through the sewage outlet 11 on the bottom surface. The design of the feed port 1 makes the introduction of liquid or gas more flexible and convenient. The setting of the sewage outlet 11 makes the discharge of waste liquid or impurities more convenient, ensuring the continuous operation of the equipment. Specific embodiment 2:

[0029] Reference Figure 1-4 , other limiting structures of the whole device are: an equipment flange 4 is provided at the position where the elliptical head 5 abuts against the filter cylinder 2, and a rotating arm shaft 7 is provided at the top of the elliptical head 5. The structure is compact and easy to install and maintain. The design of the elliptical head 5 increases the stability and aesthetics of the equipment. A visual window 6 is provided on the side of the top surface of the elliptical head 5 away from the discharge port 8. The bottom surface of the elliptical head 5 abuts against the top surface of the filter cylinder 2. The design of the visual window 6 makes the operating status of the equipment clear at a glance, which is convenient for timely detection of problems. The support legs 10 ensure the stability and load-bearing capacity of the equipment. The support legs 10 are distributed around the bottom surface of the filter cylinder 2, and the ends of the support legs 10 are bolted to the surface of the filter cylinder 2. The top of the box handle 9 is rounded, and the top of the box handle 9 is coplanar with the top surface of the filter cylinder 2. Specific embodiment three:

[0031] Reference Figure 1-4 When the whole device is actually used, the activated carbon box 3 is filled with activated carbon particles. During the actual filling, the density is gradually increased from bottom to top. By designing stepped activated carbon particles, the filtering and adsorption effect is increased, which is convenient for purification and filtration treatment.

[0032] In summary:

[0033] 1. The activated carbon box 3 is set inside the filter cylinder 2 for filtering. The entire filter is mainly filtered through the activated carbon box 3. The operator can easily take out or put in the activated carbon box 3 from the filter cylinder 2, which greatly improves the efficiency of replacing activated carbon. At the same time, the positioning ring 13 at the top of the activated carbon box 3 and the limiting ring 12 on the inner wall of the filter cylinder 2 are mutually engaged, ensuring the stability of the activated carbon box 3 during the filtering process and preventing the filtering effect from being reduced due to shaking or displacement;

[0034] 2. The visual window 6 provided on the top surface of the elliptical head 5 allows the operator to directly observe the internal conditions of the equipment, such as the state of the activated carbon, the flow of the liquid, etc., without opening the equipment, so as to timely discover and solve problems. In addition, the design of the supporting legs 10 not only ensures the stability of the equipment, but also makes the equipment more stable when placed on the ground, which is convenient for daily cleaning and maintenance.
