[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described. Example 1:

[0022] like Figure 1 As shown, this application provides an activated carbon adsorption device for wastewater treatment, including a housing 1, a drive shaft 2, a drive cylinder 3, and a filter plate 4.

[0023] The bottom of the box 1 is provided with a water inlet 101, and the box 1 is provided with a water outlet pipe 102. The water inlet 101 is located near one end of the box 1, and the water outlet pipe 102 is located near the other end of the box 1 and near the top of the box 1.

[0024] A drive shaft 2 is rotatably mounted inside the housing 1. One end of the drive shaft 2 extends out of the housing 1 and is connected to a drive motor 5 mounted on the housing 1. The drive motor 5 is connected to an external power source.

[0025] At least two filter plates 4 are spaced apart around the circumference of the drive shaft 2. Specifically, there are four, five or six filter plates 4. The filter plates 4 are made of activated carbon plates or have an overall plate structure and contain activated carbon particles inside.

[0026] During operation, the wastewater to be treated is introduced into the tank 1 through the inlet 101. Then, the drive motor 5 starts and drives the drive shaft 2 to rotate. The drive shaft 2 drives the filter plates 4 to rotate inside the tank 1, so that all the filter plates 4 can be in uniform contact with the wastewater, thereby effectively ensuring that the activated carbon plates can uniformly adsorb impurities in the wastewater. After the wastewater is treated, it overflows out of the tank 1 through the outlet pipe 102.

[0027] In this embodiment, the inlet 101 is connected to the vertical section of the three-way pipe 6. One end of the horizontal section of the three-way pipe 6 is connected to the sewage pipe to introduce the sewage to be treated, and the other end is provided with a solid impurity storage tank 7. The solid impurity storage tank 7 is a sealed tank. When sewage is introduced, if there are solid particulate impurities in the sewage, since the solid particulate impurities have greater inertia than water, when the sewage flows through the three-way pipe 6, the solid impurities are rushed forward into the solid impurity storage tank 7 in the horizontal section of the three-way pipe 6. The sewage in the solid impurity storage tank 7 flows back into the box 1 from the horizontal section of the three-way pipe 6, thereby reducing the amount of solid impurities entering the box 1 and effectively reducing the problem of filter plate 4 clogging. Example 2:

[0028] Based on Example 1, in this example, as Figure 2 As shown, there are four filter plates 4, and each filter plate 4 is connected to the drive shaft 2 through a drive cylinder 3.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, the transmission cylinder 3 includes a hollow cylindrical body 301, which is rotatably mounted on the transmission shaft 2. The bottom of the filter plate 4 is fixedly connected to the body 301. Regarding the position of the filter plate 4 and the body 301, the right side of the driving part 302 of the transmission cylinder 3 is flush with the right side of the filter plate 4, one end of the transmission cylinder 3 near the drive motor 5 is flush with one end of the filter plate 4, and the rest of the transmission cylinder 3 gradually shifts to the other side of the filter plate 4.

[0030] like Figure 5 As shown, one end of the cylinder body 301 is provided with an arc-shaped driving part 302, and the other end is provided with an arc-shaped bayonet 303. One side of the driving part 302 is flush with one side of the bayonet 303, and the other side of the driving part 302 extends in the opposite direction to the other side of the bayonet 303. As shown in the figure, the left side of the driving part 302 is flush with the left side of the bayonet 303. When the driving part 302 extends in a counterclockwise direction, the bayonet 303 extends in a clockwise direction.

[0031] like Figure 6 As shown, the central angle 'a' of the drive unit 302 is smaller than the central angle 'b' of the bayonet 303. Specifically, the difference between the central angle of the drive unit 302 and the central angle of the bayonet 303 is equal to 360 divided by the number of filter plates 4. For example, if there are 4 filter plates, the difference between the central angle of the drive unit 302 and the central angle of the bayonet 303 is 90 degrees; if there are 5 filter plates, the difference between the central angle of the drive unit 302 and the central angle of the bayonet 303 is 72 degrees; and if there are 6 filter plates, the difference between the central angle of the drive unit 302 and the central angle of the bayonet 303 is 60 degrees.

[0032] like Figure 2 As shown, the transmission cylinder 3 near the drive motor 5 is fixedly connected to the transmission shaft 2, and the cylinder body 301 of the remaining transmission cylinders 3 is rotatably mounted on the transmission shaft 2. In two adjacent transmission cylinders 3, the driving part 302 of one transmission cylinder 3 is embedded in the slot 303 of the other transmission cylinder 3.

[0033] When the drive motor 5 drives the transmission shaft 2 to rotate clockwise, as Figure 2 As shown, the right side of the drive part 302 of any one transmission cylinder 3 abuts against the right side of the bayonet 303 of another transmission cylinder 3, so that the two adjacent transmission cylinders 3 can rotate synchronously. At the same time, the filter plates 4 are evenly spaced around the circumference of the transmission shaft 2.

[0034] When the drive motor 5 drives the transmission shaft 2 to rotate counterclockwise, as Figure 7 As shown, the left side of the drive part 302 of any transmission cylinder 3 abuts against the left side of the bayonet 303 of another transmission cylinder 3. After all the filter plates 4 are rotated, they are pressed together. When the staff replaces the filter plates 4, there is no need to frequently rotate the transmission shaft 2, which greatly facilitates the disassembly and replacement of the filter plates 4 by the relevant staff.

[0035] In some specific embodiments, a limiting plate 103 is hinged to the top left edge of the housing 1. When the filter plate 4 needs to be maintained, the limiting plate 103 is rotated to the right so that it rests on the top surface of the housing 1 and extends into the housing 1. Then, by manually moving the filter plate 4, the drive shaft 2 is driven to rotate counterclockwise, so that the filter plate 4 can be placed on the limiting plate 103 one by one, thereby providing support for the filter plate 4 and effectively facilitating the replacement of the filter plate 4.

[0036] In some specific embodiments, the outer side of the transmission cylinder 3 is provided with a protective sleeve 201 (not shown in the figure). The protective sleeve 201 covers the cylinder body 301 and the bayonet 303. When in use, the drive unit 302 is embedded in the protective sleeve 201 of the adjacent transmission cylinder 3, thereby sealing the bayonet 303 through the protective sleeve 201, effectively preventing sludge in the sewage from adhering to the bayonet 303, which would prevent the drive unit 302 from rotating into place.

[0037] In some specific embodiments, each filter plate 4 is connected to the drive shaft 2 via two drive cylinders 3. The two drive cylinders 3 are respectively positioned close to both ends of the filter plate 4, which helps to improve the connection strength between the drive shaft 2 and the drive cylinders 3. At the same time, the filter plate 4 is subjected to more uniform force and is less prone to deformation and damage. Example 3:

[0038] Based on Embodiment 1 or Embodiment 2, in this embodiment, as Figure 7As shown, the filter plate 4 includes a U-shaped outer frame 401, a hollow rectangular filter screen frame 402, and pressure strips 404.

[0039] The inner wall of the outer frame 401 is provided with a slot.

[0040] like Figure 8 As shown, the filter frame 402 includes two filter boxes 403, one of which is open. The two filter boxes 403 are arranged opposite each other on their open sides, thus forming a hollow rectangular structure. The filter frame 402 is filled with carbon filler 405. The filter frame 402 is set inside the outer frame 401, and its edges are embedded in the slots, so that the filter screen is firmly connected to the filter frame 402.

[0041] A pressure strip 404 is detachably mounted on the top of the outer frame 401; specifically, the end of the pressure strip 404 is provided with a connecting hole, and a locking screw 407 passes through the connecting hole and is threaded onto the outer frame 401. Thus, by unscrewing the locking screw 407, the pressure strip 404 can be removed; or, as... Figure 9 As shown, the end of the pressure strip 404 is provided with a mounting hole 408, and a spring 409 is fixedly installed in the mounting hole 408. A connecting pin 410 is provided at each end of the spring 409. The side wall of the slot is provided with a limiting hole that cooperates with the connecting pin 410. In use, the end of the pressure strip 404 is inserted into the slot and pressed down. When the connecting pin 410 on the pressure strip 404 is inserted into the limiting hole, the pressure strip 404 can be firmly connected to the outer frame 401. When disassembling, the connecting pin 410 is pressed inward and the pressure strip 404 can be pulled out upward.

[0042] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
