Description

Technical Field

[0001] The utility model relates to the field of dry fog dust suppression equipment, in particular to a dry fog dust suppression device for a ship unloader. Background Technique

[0002] When the belt conveyor of the ship unloader is working, materials fall from the head of the belt conveyor, causing disturbed air flow inside the chute. Small particle materials are lifted by the air flow to generate dust. During the falling process of the materials, collisions occur between the material particles and between the materials and the chute, exacerbating dust generation. During the loading process, dry fog dust reduction treatment is required.

[0003] According to a dry fog dust suppression system for a ship unloader disclosed in a patent document with the existing publication number CN111422642A, it includes an air compressor, an air storage tank, a micron-level dry fog machine, a water-air distributor, a dry fog box assembly, a dry fog box controller, a filtering device, an air pipeline, a water flow pipeline, and a distribution box. The inlet of the filtering device is connected to a water source, and the outlet of the filtering device is connected to the micron-level dry fog machine through the water flow pipeline. The distribution box is electrically connected to the air compressor, the micron-level dry fog machine, the water-air distributor, and the dry fog box controller. When this technical solution is in use, a vibrator installed inside the nozzle can shatter the water mist when it starts to freeze, preventing blockage of the nozzle due to icing. In addition, sedimentation and filtration of the filtering device can filter out impurities with large particle sizes, avoiding blockage of the nozzle. For the above technical solution, although this solution avoids icing, it is inconvenient to use because the spraying direction cannot be adjusted during use, and the nozzle cannot be shielded and protected when not in use. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a dry fog dust suppression device for a ship unloader to solve the problems raised in the above background technique. The structure of the utility model is novel. When in use, the power mechanism drives the fixed pipe to rotate, and the fixed pipe drives the dry fog nozzle to tilt and adjust the spraying position and direction for dust suppression and dust reduction at different positions. In addition, when not in use, the dry fog nozzle contacts the rubber plate for sealing protection.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A dry fog dust suppression device for a ship unloader includes a fixed seat. One end of the fixed seat is respectively fixedly installed with a power mechanism and a displacement mechanism. A fixed groove is opened at the top of the fixed seat. A fixed frame and a support frame are respectively movably installed inside the fixed groove. The fixed frame and the support frame are both installed inside the fixed groove through a support mechanism. A frame is movably installed between the fixed frame and the support frame. The frame is installed on the ship unloader. A fixing bolt is rotatably installed on the fixed frame and the support frame.

[0006] Furthermore, an output shaft is installed on the power mechanism. One end of the output shaft is fixed with a fixed pipe, and a dry mist nozzle is fixedly installed on the fixed pipe. One end of the fixed pipe is installed with a rotary joint, and a water supply pipe is installed on the rotary joint.

[0007] Furthermore, an opening is formed on one side of the fixed seat, and a slot is formed on the other side of the fixed seat. The opening is matched with the dry mist nozzle.

[0008] Furthermore, a movable plate is installed on the displacement mechanism. The movable plate is movably installed on one side of the slot, and a connecting groove is formed on the movable plate.

[0009] Furthermore, the connecting groove is matched with the dry mist nozzle, and a rubber plate is fixedly installed on the movable plate.

[0010] Furthermore, a limiting block is welded to the bottoms of the fixed frame and the support frame. A limiting groove is formed on the inner wall of the fixed groove, and the limiting block is movably installed inside the limiting groove.

[0011] Advantages of the present utility model:

[0012] 1. When the dry mist dust suppression device for a ship unloader is in use, the power mechanism drives the fixed pipe to rotate, and the fixed pipe drives the dry mist nozzle to tilt and adjust the position and direction of spraying, so as to suppress and reduce dust at different positions. In addition, when not in use, the dry mist nozzle contacts the rubber plate for sealing protection.

[0013] 2. When the dry mist dust suppression device for a ship unloader is installed, the fixed frame and the support frame move inward simultaneously to quickly clamp the frame. The clamping realizes the positioning installation of the fixed seat. Under the extrusion of the fixing bolt, the fixed frame and the limiting frame are limited on the frame to support and fix the fixed seat. Description of the drawings

[0019] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a dry mist dust suppression device for a ship unloader, including a fixed seat 1, one end of the fixed seat 1 is respectively fixedly installed with a power mechanism 2 and a displacement mechanism 3, a fixed groove 4 is opened at the top of the fixed seat 1, a fixed frame 5 and a support frame 6 are respectively movably installed inside the fixed groove 4, the fixed frame 5 and the support frame 6 are both installed inside the fixed groove 4 through a support mechanism 8, a frame 19 is movably installed between the fixed frame 5 and the support frame 6, the frame 19 is installed on the ship unloader, a fixed bolt 7 is rotatably installed on the fixed frame 5 and the support frame 6, an output shaft 11 is installed on the power mechanism 2, one end of the output shaft 11 is fixed with a fixed pipe 12, a dry mist nozzle 13 is fixedly installed on the fixed pipe 12, one end of the fixed pipe 12 is installed with a rotary joint 18, a water supply pipe 9 is installed on the rotary joint 18, the power mechanism 2 is a DC motor, the DC motor drives the rotation of the fixed pipe 12, and the fixed pipe 12 rotates to adjust the inclination direction of the dry mist nozzle 13, the displacement mechanism 3 is a linear reciprocating electric push rod, and the displacement mechanism 3 pushes the movable plate 15 to move to adjust the position of the rubber plate 17.

[0020] In this embodiment, an opening 10 is opened on one side of the fixed seat 1, a groove 14 is opened on the other side of the fixed seat 1, the opening 10 cooperates with the dry mist nozzle 13, a movable plate 15 is installed on the displacement mechanism 3, the movable plate 15 is movably installed on one side of the groove 14, a connection groove 16 is opened on the movable plate 15, the connection groove 16 cooperates with the dry mist nozzle 13, a rubber plate 17 is fixedly installed on the movable plate 15, limit blocks 20 are welded at the bottoms of the fixed frame 5 and the support frame 6, a limit groove is opened on the inner wall of the fixed groove 4, and the limit blocks 20 are movably installed inside the limit groove. The support mechanism 8 is a support spring, and the support spring pushes the fixed frame 5 and the support frame 6 to move inward simultaneously to clamp and fix the frame 19.

[0021] When the device is in use, the fixing frame 5 and the support frame 6 are opened to both sides inside the fixing groove 4. When the fixing frame 5 and the support frame 6 are opened, they squeeze the support mechanism 8, and the support mechanism 8 contracts under the squeeze. After contraction, the fixing frame 5 and the support frame 6 are opened to a certain width. Place the frame 19 between the fixing frame 5 and the support frame 6.

Connect the water supply pipe 9 to an external water pipe. When in use, the power mechanism 2 drives the fixed pipe 12 to rotate. The rotation makes one end of the dry fog nozzle 13 cooperate with the opening 10 to spray dust reduction to one side. The dry fog nozzle 13 can spray vertically downward under rotation. In addition, when it is necessary to move the dry fog nozzle 13 in the direction of the slot 14, the displacement mechanism 3 drives the movable plate 15 to move. When the connection groove 16 on the movable plate 15 is aligned with the dry fog nozzle 13, the water mist sprays to one side from the slot 14. In addition, when the dust reduction of this device is not required, the movable plate 15 moves to align the rubber plate 17 with the dry fog nozzle 13. Under the rotation of the dry fog nozzle 13, the dry fog nozzle 13 squeezes the rubber plate 17. After extrusion, the rubber plate 17 wraps and seals one end of the dry fog nozzle 13 to prevent the external dust from blocking the dry fog nozzle 13.
