[0002] In industries like energy and chemical engineering, filtering water containing impurities like slag is a common practice for reuse or discharge, placing higher demands on the effectiveness and efficiency of water treatment. Existing cold water filtration systems use nylon or plastic mesh bags with 3mm mesh openings for the second and third stages of contamination control. These four-sided pyramidal mesh bags often require manual removal of slag from the small end, and the mesh openings must be regularly removed from the water for cleaning and unclogging. This results in a short service life. This requires significant manual labor, is time-consuming, and inefficient, making it difficult to meet the requirements of automated, efficient filtration.

[0047] Example

[0048] like Figure 1-7 As shown, the rotary net bag type trash intercepting system provided in this embodiment includes a first supporting platform 1, a second supporting platform 2, a solid-liquid separation system 4 and a filtration system 3, and the solid-liquid separation system 4 is arranged on the first supporting platform 1.

[0049] The filtration system 3 includes a matching conical net bag 31, a suction pump 32 and a flushing device 33. The conical net bag 31 is composed of a number of detachable mesh plates or filter screens connected by a support frame 311. The conical net bag 31 has a large port and a small port. The top of the large port and the top of the small port of the conical net bag 31 are both set above the design water level, which can ensure that the busbar at the highest point of the conical net bag 31 can be completely exposed to the horizontal plane. The diameter of the large port of the conical net bag 31 is larger than the diameter of the small port. The width of the fan ring used to enclose the conical net bag 31 is the busbar of the conical net bag 31. The distance from the center of the large port to the center of the small port is the height of the conical net bag 31. Figure 2The figure shows the busbars and height of the conical net bag 31. A front support ring is provided at the large end of the conical net bag 31, which is tilted downward and connected to the second support platform 2 via the front support ring. A rear support ring is provided at the small end of the conical net bag 31, which is mounted on the first support platform 1 via a rear support seat. A suction pump 32 is installed on the first support platform 1 and connected to the small end of the conical net bag 31 via a pipe. The large end of the conical net bag 31 is positioned toward the incoming water. The conical shape of the net bag allows aquatic plants and debris to be concentrated by the water flow toward the small end of the conical net bag 31, facilitating extraction by the suction pump 32.

[0050] The filtration system 3 is also equipped with a drive mechanism, which can be located at the large or small end of the conical net bag 1 and is used to drive the conical net bag 31 to rotate. Specifically, the drive mechanism includes a drive gear 11. A driven gear 312 is located at the large or small end of the conical net bag 31, which is gear-driven with the drive gear 11. In this embodiment, the drive mechanism and driven gear 312 are located at the large end of the conical net bag 31. Driven by a drive motor or hydraulic motor, the drive gear 11 rotates the conical net bag 31 about the axis of the conical net bag 31's high line.

[0051] The rotating net bag-type waste interception system provided in this embodiment comprises a flushing device 33, which includes a flushing pipe 331 and a plurality of flushing nozzles 332 arranged along the flushing pipe 331. The flushing pipe 331 is located above or to the side of the conical net bag 31. A driving device rotates the conical net bag 31 about the axis of the high line of the conical net bag 31. The flushing device 33 continuously flushes the mesh of the conical net bag 31 above the water surface, flushing aquatic plants and debris attached to the conical net bag 31 into the water. This keeps the mesh of the conical net bag 31 clean, prevents clogging, and ensures a sufficient flow rate.

[0052] In this embodiment, a filter screen is provided on the second support platform 2, which surrounds the large port of the conical mesh bag 31. The water inlet of the nylon mesh bag used in the prior art is a rectangular inlet. In comparison, the rectangular inlet is 21.5% larger than the circular inlet with a diameter equal to its side length. Therefore, the number of conical mesh bags 31 can be increased on the water flow cross section to increase the water intake area, and the junction of two adjacent conical mesh bags 31 is connected with a filter screen. According to the needs of the pollution interception path, the conical mesh bags 31 can be arranged in a straight line or in an arc along the water flow cross section. The filter screen serves as a flushing blind spot of the flushing device 33 and needs to be regularly cleaned manually with a high-pressure water gun that can be connected to underwater video equipment.

[0053] In the rotating net bag-type waste interception system provided in this embodiment, during actual operation, the water flow sucked by the suction pump 32 often contains debris such as plastic tape and fishing net lines, which can cause the suction pump 32 to become stuck. Therefore, the filtration system 3 also includes an anti-blocking device 34, which is arranged between the conical net bag 31 and the suction pump 32. The anti-blocking device 34 can crush these debris to ensure the normal operation of the suction pump 32. Specifically, the anti-blocking device 34 is a pulverizer for crushing aquatic plants and debris in the water.

[0054] The rotating net bag-type waste interception system provided in this embodiment features a spiral propeller blade inside the conical net bag 31, which directs debris in the water toward the small port of the conical net bag 31, preventing it from remaining stationary on the water surface and blocking the flow. As the conical net bag 31 rotates, a flushing device continuously flushes debris attached to the mesh of the portion of the conical net bag 31 that has been rotated above the water surface into the water. Aquatic plants and animals, along with debris, are collected by the water flow and the spiral propeller blades at the small port of the conical net bag 31. Under the action of a suction pump 32, the debris enters an anti-blocking device 34 for fragmentation. The fragmented solid-liquid mixture then flows through a sewage pipe 5 and enters a solid-liquid separation system 4 for solid-liquid separation. The solid-liquid separation system 4 comprises a solid-liquid separation device, a slag collection box, and a drain outlet. After separation by the solid-liquid separation device, the solid slag enters the slag collection box. When the box is full, a sensor automatically signals the box, controlling the valve at the bottom of the slag collection box to open, unloading the slag onto a transfer vehicle for transport to a designated location. The drain outlet can be used to discharge directly into the sea or into an open water channel.

[0055] Such a structural design can make it possible, first, to use water flow and spiral propulsion blades to continuously collect aquatic plants and animals and debris to the small port of the conical net bag 31, the suction pump 32 sucks the impurities into the anti-blocking device 34 for crushing, and transports the crushed solid-liquid mixture to the solid-liquid separation system 4 for solid-liquid separation, thereby realizing the automated operation of the pollution interception system, high filtration efficiency, and greatly reducing the manpower costs of operation and maintenance; second, the conical net bag 31 is composed of a detachable mesh plate or filter screen, and the rotating conical net bag 31 is continuously flushed by the flushing device 33, which can prevent the mesh from being blocked, ensure the flow of seawater, and greatly improve the service life of the conical net bag 31; third, the conical net bag 31, the suction pump 32, the flushing device 33 and the anti-blocking device 34 are modularly designed, with a high degree of integration, a simple installation foundation, and a short construction and commissioning cycle.

[0056] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this utility model.
