Description

Technical Field

[0002] The multi-layer filtration wastewater treatment device is an environmental protection device, which is mainly used to treat wastewater, especially those containing suspended matter, impurities and pollutants. Its core principle is to screen and filter wastewater through multiple filter layers to achieve zero discharge or recycling of wastewater. For example, patent number CN202123441708.5 is a wastewater treatment device with multi-layer filtration. The device has the following shortcomings:

[0003] The device is provided with a filter plate, an activated carbon layer, a through hole, a slider and a slideway. The wastewater enters the activated carbon layer through the through hole on the left side of the filter plate. The through hole performs the first filtration on the wastewater to filter out the larger impurities, and then the wastewater is filtered twice through the activated carbon layer. The filter device used in the device is not convenient to adjust and disassemble once installed. At the same time, a filter device can only filter the corresponding wastewater. Therefore, it cannot effectively filter when treating other wastewater. Other devices need to be used for filtering, which leads to increased use costs. The filter device cannot be adjusted according to the type of wastewater.

[0004] At the same time, the filter plate of the above device is fixed and immovable during the filtering process, and the solid matter inside the filter hole cannot be effectively separated, so it is easy to get clogged, resulting in a decrease in the ability to filter solids.

[0037] A water outlet pipe 9 is provided through the middle of the lower surface of the box body 1 and the box door 5 on the same side, and the water outlet pipe 9 can discharge the filtered water.

[0038] In this device, the motor 3, the filter screen 16, the hinge 6, and the torsion spring 83 are all prior art and will not be described in detail here.

[0039] The device also requires the use of a rotating pipe joint to connect the water inlet pipe 81 to the wastewater pipe. Since the rotating pipe joint is a prior art, it will not be elaborated in detail here.

[0040] Principle and process of this utility model:

[0041] First, place the box body 1 on the ground, then pull the handle 7 to open the box door 5, insert the required filter screen 16 that can achieve different filtering effects into the block 15 set on the outer surface of the air duct 13, and after placing the filter screen 16, close the box door 5, and then connect the wastewater pipe to the water inlet pipe 81 located on both sides of the upper part of the box body 1 through a rotating pipe joint.

[0042] Then, the control switch of the motor 3 is turned on to rotate the output end of the motor 3, which drives the gear ring 17 to rotate, and at the same time drives the limit ring 19 and the water inlet pipe 81 to rotate, and then drives the circular filter screen 11 to rotate. When the water inlet pipe 81 rotates, the protrusion 85 welded on the outer surface of the water inlet pipe 81 also rotates. When the protrusion 85 rotates, it fits with the surface of one side of the T-shaped slider 84 and pushes the T-shaped slider 84 to rotate together. Since the T-shaped slider 84 is slidably arranged in the inner cavity of the T-shaped groove 86 on one side of the inner surface of the slip ring 82, and the slip ring 82 is welded to the scraper 12, the sliding ring 82 is welded to the scraper 12. The T-shaped slider 84 is fixedly connected, so when the protrusion 85 pushes the T-shaped slider 84 to rotate, the slip ring 82 and the scraper 12 are also pushed. When the scraper 12 is pushed to the connection between the other side of the box cover 2 and the box body 1, the scraper 12 will be limited, and the T-shaped slider 84 will also be limited. At this time, the protrusion 85 continues to squeeze the inclined surface of the T-shaped slider 84, so that the T-shaped slider 84 slides into the inner cavity of the T-shaped groove 86 and squeezes the spring 87. When the protrusion 85 is separated from the T-shaped slider 84, the spring 87 pushes the T-shaped slider 84 out under the reaction force to achieve circulation.

[0043] When the thrust of the protrusion 85 on the T-shaped slide block 84 disappears, the torsion spring 83 rotates the scraper 12, the slip ring 82 and the T-shaped slide block 84 counterclockwise back to their original positions under the reaction force, thus realizing the cyclic cleaning of the box cover 2.

[0044] When the circular filter screen 11 rotates, the fan blades 18 are driven to rotate. The rotation of the fan blades 18 transmits air to the lower part of the box body 1 through the air supply holes 20 and the inner cavity of the air duct 13, so that some harmful substances in the wastewater at the bottom of the box body 1 can float on the water surface.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
