[0029] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0030] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example

[0032] Please see Figures 1-5 As shown, this embodiment discloses a wastewater filtration device, including a fixed plate 1. Connecting blocks 2 are provided at both end faces of the fixed plate 1, and each connecting block 2 has a connecting hole 20 inside. In this embodiment, the two connecting holes 20 are threaded holes. Multiple insert rods 3 are provided on the top of the fixed plate 1, each insert rod 3 being perpendicular to the top of the fixed plate 1, i.e., the central axis of each insert rod 3 is aligned with the normal direction of the top surface of the fixed plate 1. Adjustment components 6 are provided on the top of the fixed plate 1 near its two ends. Each adjustment component 6 is located inside an adjacent connecting hole 20, allowing the two adjustment components 6 to be rotatably connected to the fixed plate 1 through corresponding connecting holes 20.

[0033] Specifically, each of the aforementioned adjustment components 6 includes a motor 60 and a screw. The motor 60 is disposed inside the inner wall of the recycling tank 4. In actual use, a cavity for housing the motor 60 needs to be pre-formed on the inner wall of the recycling tank 4, and this cavity is connected to the interior of the recycling tank 4. This connection is achieved by creating a connecting hole on the inner wall of the recycling tank 4, allowing the connecting hole to connect the cavity to the interior space of the recycling tank 4. A screw is installed at the output end of the motor 60, enabling the motor 60 to drive the screw to rotate during operation. The screw is threadedly connected to the fixing plate 1 through a corresponding connecting hole 20. Thus, controlling the operation of the motor 60 causes the screw to rotate. After the screw rotates, because the screw is threadedly connected to the fixing plate 1 through the connecting hole 20, and the fixing plate 1 does not rotate, the fixing plate 1 can reciprocate along the central axis of the screw under the rotational force of the screw.

[0034] In actual use, a filter screen 5 is arranged at the top inlet of the recovery tank 4, which is used to filter the sewage for cleaning the body of the loading trolley, and the sewage enters the recovery tank 4 for recovery treatment through the filter screen 5. Among them, the anhydrous edema may contain large particle impurities, and such large particle impurities will accumulate on the top of the filter screen 5 or in the filter holes 50 of the filter screen 5, causing the filter screen 5 to be blocked. In this regard, after the two motors 60 are operated, each motor 60 drives the corresponding screw rod to rotate, and the screw rod drives the fixed plate 1 to move towards the direction of the filter screen 5. It should be noted that the number of the insertion rods 3 is consistent with the number of the filter holes 50 on the filter screen 5, and the central axis of each insertion rod 3 coincides with the central axis of each corresponding filter hole 50. After the fixed plate 1 moves to the inside of each insertion rod 3 entering the corresponding filter hole 50, the motor 60 is stopped. At this time, each insertion rod 3 can push the large particle impurities in the filter hole 50 out of the inside of the filter hole 50 to the outer surface of the filter screen 5, and then the surface of the filter screen 5 can be cleaned. When the large particle impurities in the filter hole 50 are cleaned, the motor 60 is operated, and the motor 60 is opposite to the previous direction. At this time, the fixed plate 1 is driven by the screw rod to move along the central axis of the screw rod towards the inside of the recovery tank 4. After each insertion rod 3 is moved out of the corresponding filter hole 50 by a certain distance, the motor 60 is stopped. At this time, the recovery of the cleaning sewage can be continued.

[0035] In the above, the fixed plate 1 is provided with a plurality of through holes 10 on the top thereof, and each through hole 10 and each insertion rod 3 are arranged alternately. Specifically, four adjacent insertion rods 3 form a square, and the through hole 10 is located at the middle position of the square, that is, the central axis of the through hole 10 coincides with the central axis of the square. By arranging a plurality of through holes 10 on the top of the fixed plate 1, the sewage entering the recovery tank 4 through the filter screen 5 will not accumulate on the top of the fixed plate 1, but can flow out to the inside of the recovery tank 4 for recovery.

[0036] A limiting ring 30 is arranged on the outer wall surface of each insertion rod 3. When the motor 60 is running, the motor 60 drives the screw rod to rotate, and the screw rod drives the fixed plate 1 to move towards the direction of the filter screen 5. After the insertion rod 3 at the top of the fixed plate 1 enters the filter hole 50, the motor 60 needs to be stopped. If the insertion rod 3 protrudes too much from the surface of the filter screen 5, the large-particle impurities that are pushed out of the filter hole 50 will accumulate between the adjacent insertion rods 3, which makes it difficult to clean the large-particle impurities on the surface of the filter screen 5. If the insertion rod 3 is retracted, the large-particle impurities will return to the inside of the filter hole 50, which requires accurate control of the start and stop of the motor 60 and increases the overall cost. Therefore, the limiting ring 30 is arranged on the outer wall surface of each insertion rod 3 to limit the insertion rod 3. It is worth noting that when the top of the limiting ring 30 contacts the inner top of the filter screen 5, the top of the insertion rod 3 is flush with the top surface of the filter screen 5.

[0037] An inclined surface is arranged at the top of the fixed plate 1 and near the two ends of the fixed plate 1. Each inclined surface is inclined towards the center axis of the adjacent screw rod in the upward direction. When the motor 60 is not running, the multiple insertion rods 3 at the top of the fixed plate 1 are away from the filter screen 5, and the sewage enters the inside of the recovery tank 4 through the filter screen 5 for recovery. During the process of the sewage entering the recovery tank 4, water splashes will be generated on the fixed plate 1, and part of the small-particle impurities will move towards the two ends of the fixed plate 1 after being impacted. The water splashes will be attached to the two ends of the fixed plate 1. With the passage of time, the attached water droplets will increase and gather together to form accumulated water at the two ends of the fixed plate 1, which will affect the operation of the screw rod and the connecting hole 20. Therefore, the inclined surface is arranged at the top of the fixed plate 1 near the two ends of the fixed plate 1 to prevent the accumulation of water and particle impurities.

[0038] The top of each limiting ring 30 and the inner wall surface of the fixed plate 1 at the through hole 10 are arc-shaped. The arrangement of the arc surface can prevent the accumulation of water and particle impurities at the top of the limiting ring 30 and the top of the fixed plate 1. In addition, if there is a small amount of particle impurities accumulated at the top of the fixed plate 1 or the top of the limiting ring 30, a vibrating machine can be arranged at the top of the fixed plate 1 or the top of the limiting ring 30. The vibrating machine can vibrate the fixed plate 1 by vibration to shake off the particle impurities at the top of the fixed plate 1 or the top of the limiting ring 30.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
