Description

Technical Field

[0001] This invention relates to a filtration and collection device for water inlet of a power plant. Background Technology

[0002] Currently, the commonly known filtration devices for power plant intakes are ordinary fishing nets used for interception. These nets are used to generate electricity by utilizing seawater at the seaside, such as the cold source intake of nuclear power plants. However, the efficiency of the fishing nets is greatly reduced due to the accumulation and attachment of marine organisms. In this case, crew members need to manually retrieve the nets by boat, which is time-consuming, labor-intensive, and inefficient. Furthermore, because the water flow at the power plant intake is rapid, there are significant safety hazards for crew members when retrieving the nets by boat. Summary of the Invention

[0003] In view of this, the present invention provides a power plant inlet filtration and collection device that can effectively filter and remove contaminants, improve filtration efficiency, and avoid crew members going into the water, thus improving safety.

[0004] This invention discloses a power plant inlet filtration and collection device, comprising:

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As shown in the figure, this invention discloses a power plant inlet filtration and collection device, comprising:

[0028] The filter device 1 includes a needle cloth 105 and a rotating shaft, and is used to filter water, lift and transfer dirt.

[0029] The cleaning device 2 includes a rotating shaft and a needle cloth 202, which is used to clean dirt and clean the filter device;

[0030] The cutting device 3 includes a rotating shaft and a needle cloth 302, and is used to cut dirt;

[0031] The recycling device 4 includes a rotating shaft and a needle cloth 402 for recycling waste;

[0032] The filter device has four rotating shafts: rotating shaft 101, rotating shaft 102, rotating shaft 103, and rotating shaft 104. The two upper rotating shafts 103 and 104 are parallel. The cleaning device is located at the upper end of the filter device, and the cleaning device has two parallel rotating shafts 201. The recycling device has two parallel rotating shafts 401, and the recycling device's rotating shaft is located below the two upper rotating shafts of the filter device. The cutting device has two rotating shafts 301, and the upper rotating shaft of the cutting device is located between the needle cloth 202 of the cleaning device and the needle cloth 402 of the recycling device.

[0033] In one embodiment of the present invention, the needle tips on the needle cloth 105 of the filter device are vertically upward, which can effectively hold and transfer the dirt intercepted by the filter.

[0034] The filter and slitting devices have multiple evenly distributed holes on their needle cloth. These holes are used to filter water, allowing water containing small amounts of tiny pollutants to enter the power plant's inlet for the next filtration stage. The holes on the needle cloth of the slitting device also serve a filtering function. This embodiment of the invention is suitable for preliminary filtration, used to filter larger objects such as jellyfish, fish, and shrimp.

[0035] In one embodiment of the present invention, the direction of needle cloth movement between the two rotating shafts at the top of the filter device is the same as the direction of water flow.

[0036] In one embodiment of the present invention, the bottom of the bearing seats 5 of the two rotating shafts at the lower end of the filter device 1 is installed in the mounting groove 7. The two ends of the bearing seats 5 are respectively connected to the hydraulic cylinders 8. The hydraulic cylinders are used to drive the bearing seats to move a very small distance. The bottom of the bearing seats 5 is provided with two fixing holes. Multiple mounting holes are evenly provided outside the mounting groove 7. The mounting groove and the bearing seats are fixed by fixing pins 6.

[0037] This invention fine-tunes the water-facing angle of the needle cloth by adjusting the positions of the two rotating shafts at the bottom of the filter device. When there is less dirt in the water, the water-facing angle can be appropriately increased to accelerate the transfer speed of dirt and improve the filtration efficiency.

[0038] In one embodiment of the present invention, the needle tip 2021 of the cleaning device needle cloth is parallel to the needle tip 1051 of the filter device needle cloth, so that dirt is not easily trapped deep in the needle cloth when the cleaning device is working, thus extending its service life.

[0039] The needle tips of the two adjacent needle cloths of the cutting device and the filter device are parallel and opposite each other. When working, the dirt is held by the needle cloths of the filter device and the cutting device at the same time, forming an effective tearing state and playing a cutting role.

[0040] In one embodiment of the present invention, the rotation direction of the rotating shaft of the filter device is opposite to that of the rotating shaft of the cleaning device, and the moving direction of the needle cloth at the top of the filter device is the same as that of the moving direction of the needle cloth at the bottom of the cleaning device, thus completing the cleaning work; the rotating direction of the rotating shaft of the slitting device is the same as that of the rotating shaft of the filter device, and the moving direction of the adjacent needle cloth of the slitting device is opposite to that of the filter device.

[0041] In one embodiment of the present invention, the rotational speed of the cleaning device's rotating shaft is 2 to 3 times that of the filter device's rotating shaft. Due to the speed difference, the cleaning device's needle cloth can easily transfer dirt from the filter device's needle cloth, thus completing the dirt cleaning and transfer function. The rotational speed of the cutting device is less than that of the cleaning device's rotating shaft, and the rotational speed of the cutting device's rotating shaft is 1.2 to 2 times that of the filter device's rotating shaft. This not only allows it to work with the filter device to cut dirt, but also allows it to work with the cleaning device to complete the cleaning work.

[0042] In one embodiment of the present invention, the rotation axes on the left side of the cutting device and the cleaning device are both projected onto the needle cloth on the top of the recycling device. The rotation axis on the left side of the cutting device is located between the rotation axis on the left side of the cleaning device and the rotation axis on the right side of the recycling device. The needle tips of the two adjacent needle cloths of the recycling device and the filtering device cross or the needle tips of the needle cloth of the recycling device are perpendicular to the upward direction, which plays the role of supporting the dirt.

[0043] In one embodiment of the present invention, the rotating shaft of the recycling device rotates in the same direction as the rotating shaft of the filtering device, and the rotational speed of the rotating shaft of the recycling device is 1.2 to 1.5 times that of the rotating shaft of the cleaning device.

[0044] In one embodiment of the invention, a support mesh plate is also included, located at the lower end of the needle cloth at the top of the filter device and on the rear side of the needle cloth facing the water flow direction. The support mesh plate can bear a large amount of dirt to adapt to harsh working conditions with a large amount of dirt.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
