Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to an energy-saving and emission-reduction system for a port hopper fan. Background Technology

[0002] In the unloading of bulk cargo at ports and wharves, the combination of gantry cranes, mobile hoppers, and truck transportation has become a widely adopted solution for port owners due to its high flexibility and low initial investment. During the loading of bulk cargo onto trucks, negative pressure dust suppression using fans is typically employed to reduce the impact of dust on the environment and the health of on-site personnel. However, in actual operations, due to factors such as vehicle scheduling, the loading process is not continuous, resulting in extended periods without loading. If the fans continue to operate at full speed during these periods, it will lead to significant electricity waste and increased operating costs, which contradicts the current trend of energy conservation and emission reduction.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: like Figures 1-4 As shown, this embodiment includes a funnel 1, a gantry 2, a set of wheels 3, and a ladder platform 4. A ladder platform 4 is provided on the outer side of the funnel 1, and a gantry 2 is provided on the outer side of the ladder platform 4. The lower ends of the vertical bars at the four corners of the gantry 2 are each connected to a fixing rope 15 via a buckle. A positioning piece 16 is fixed to the other end of each fixing rope 15, and the positioning piece 16 is connected to the ground via a locking bolt. Fixing rods 5 are welded and fixed to the side wall of the vertical plate of the gantry 2 away from the center. Reinforcing rods 17 are fixed to the top wall of the fixing rods 5 and to the horizontal bars of the gantry 2. The upper end of the reinforcing rods 17 is tilted and fixed to the vertical bars of the gantry 2. A set of wheels 3 is provided at the bottom of each fixing rod 5. A traction frame 13 is provided below one side of the gantry 2. A hinge frame 14 is spun to the front and rear sides of one side wall of the traction frame 13 via axles. The other side of the hinge frame 14 is connected to the horizontal bar at the bottom of the gantry 2 via axles. It also includes: Ultrasonic radar 6, there are two ultrasonic radars 6, and they are symmetrically arranged on both sides of the funnel 1. The ultrasonic radar 6 is connected to the PLC control system of the funnel 1, and the PLC control system of the funnel 1 is connected to the main control computer of the port. Two microwave radar scanners 7 are provided, and they are respectively fixed to the lower edge of the second-floor platform of the ladder platform 4 by bolts. The microwave radar scanners 7 are connected to the main control computer of the port. A rectangular frame 8 is fixed to the top wall of the funnel 1 by bolts. The rectangular frame 8 is located on the inner side of the top of the climbing platform 4. Several exhaust ports 8-1 are equally spaced on the four walls of the rectangular frame 8. Each exhaust port 8-1 is equipped with an exhaust hinge 11. The blades of the exhaust hinge 11 are inclined downward on the side adjacent to the funnel 1. There are several fans 9, which are respectively set at the four corners of the ladder platform 4. Each fan 9 has an exhaust pipe 10 connected to its exhaust port. The exhaust port on the exhaust pipe 10 is connected to the exhaust port 8-1. The control system of the fan 9 is connected to the PLC control system of the funnel 1. A protective frame 12 is fixed on the top wall of the ladder platform 4. The protective frame 12 is located on the outside of the fan 9.

[0018] When using this utility model, when a vehicle walks into the work area, the microwave radar scanner 7 scans the vehicle's length direction and scans the vehicle's position in real time. Then, the main control computer transmits the vehicle entry signal to the PLC control system of the funnel 1. The PLC control system controls the fan 9 to run at full speed to ensure the dust removal effect. After the vehicle leaves, if no vehicle enters within two minutes, the PLC control system outputs a control signal to control the fan 9 to run at slow speed, effectively avoiding the energy waste of the fan running at full speed when there are no vehicles working. The ultrasonic radar 6 monitors the grab bucket of the door panel, and transmits the real-time distance signal of the grab bucket above the funnel 1 to the PLC control system of the funnel 1. When the distance is less than the set value, the PLC control system determines that the grab bucket is above the funnel 1 and is about to start the material discharge operation, and then controls the fan 9 to run at high speed to enhance the dust removal effect. When the distance is less than the set value, the grab bucket ends the material discharge operation. If the distance is not less than the set value within 2 minutes, the PLC outputs a control signal to control the fan 9 to run at a slow speed to achieve energy saving.

[0019] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. The position of the vehicle and grab bucket is monitored in real time by microwave radar scanner 7 and ultrasonic radar 6. The PLC system intelligently adjusts the speed of fan 9 to run at full speed or slow speed, which not only ensures efficient dust removal during operation, but also avoids energy waste when idle, and significantly reduces operating costs. 2. The ultrasonic radar 6 detects the distance between the grab bucket and the funnel 1 in real time to prevent the risk of collision; the microwave radar scanner 7 scans the vehicle position and links with the main control computer to ensure accurate vehicle positioning, reduce manual intervention, and improve the safety and automation level of the loading and unloading process. 3. The gantry 2 is equipped with a reinforcing rod 17, a traction frame 13 and a hinge frame 14 to improve overall rigidity; the traveling wheel set 3, combined with the ground-fixed rope 15, enables rapid positioning and movement, adapting to the complex working environment of the port and balancing the equipment's stability and mobility requirements. 4. The inclined exhaust hinge 11 and the multi-fan system 9 form a directional dust removal airflow to suppress dust diffusion; the protective frame 12 protects key components; the ladder platform 4 has a layered layout for easy maintenance; the modular design reduces maintenance difficulty and extends equipment life.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
