Description

Technical Field

[0001] The utility model belongs to the technical field of port engineering, and particularly relates to a sediment screening device for port engineering construction. Background Art

[0002] A port refers to a transportation hub with water-land intermodal equipment and conditions for ships to safely enter and berth, while port engineering refers to the engineering technology of various engineering facilities required for building a port, including port site selection, engineering planning and design, and the construction of various facilities (such as various buildings, loading and unloading equipment, mooring buoys, navigation aids, etc.);

[0003] In the prior art, during the process of port engineering construction, it is necessary to separate the sediment in the excavated silt to facilitate the treatment of the sediment. Generally, the existing sediment separation is carried out by screening the sediment through a screening device. During the screening process of the screening device for sediment, since the sizes of the sediment in different areas are different, the screen of the screening device needs to be replaced with a screen suitable for the sediment size in the current area. However, the screen is fixedly connected to the screening device, so it is very troublesome to replace, which will affect the construction efficiency. Therefore, we propose a sediment screening device for port engineering construction. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sediment screening device for port engineering construction, so as to solve the technical problem that the existing screening device is slow and troublesome to replace different screens during the screening process of sediment, and achieve the purpose of quickly screening sediment of different sizes.

[0005] To solve the above technical problem, the utility model provides a sediment screening device for port engineering construction, including the overall screening device. A screening bed is installed on the top of the overall screening device. The screening bed is made of stainless steel, and the inclination angle of the screening bed is 30 degrees. A sliding groove is opened on the front surface of the screening bed, and the inclination angle of the sliding groove is also 30 degrees. A first frame is slidably connected to the inside of the screening bed through the inside of the sliding groove. A first screen is fixedly connected to the inside of the first frame, and the mesh number of the first screen is 40 meshes. A second frame is fixedly connected to the bottom of the first frame and inside the screening bed, and the second frame is attached to the first frame. A second screen is fixedly connected to the inside of the second frame, and the mesh number of the second screen is also 40 meshes. Three electric push rods are fixedly connected to the front surface of the first frame at equal intervals.

[0006] Furthermore, a first discharge port is opened on the left side surface of the screening bed. A discharge plate is fixedly connected to the left side surface of the first discharge port and on the left side surface of the screening bed. The material of the discharge plate is stainless steel. The height of the left side surface of the first frame is located in the middle of the first discharge port.

[0007] Through the above solution, the filtered sediment can slide down conveniently through the blanking plate made of stainless steel material, so that the blanking can be smoother.

[0008] Furthermore, a second blanking port is opened near the left side at the bottom of the sieve bed, and the second blanking port is communicated with the inside of the sieve bed.

[0009] Through the above solution, the filtered sediment inside the sieve bed can be discharged conveniently through the blanking port.

[0010] Furthermore, damping springs are fixedly connected to the four corners at the bottom of the sieve bed, and support columns are fixedly connected to the bottoms of the damping springs.

[0011] Furthermore, a frame is fixedly connected to the bottom of the support column, support feet are fixedly connected to the four corners at the bottom of the frame, and both the frame and the support feet are made of iron metal material.

[0012] Furthermore, support rollers are fixedly connected to the front and back of the frame and on the front and back of the sieve bed. A hopper is fixedly connected to the opposite side surfaces of the support rollers. The hopper is made of stainless steel material, and the bottom of the hopper is located above the first sieve mesh.

[0013] Furthermore, a triangular protrusion is fixedly connected to the center of the bottom of the sieve bed, and a vibration motor is fixedly connected to the right side surface of the protrusion.

[0014] Through the above solution, through the setting of the vibration motor, the vibration motor can effectively vibrate the protrusion, thereby driving the sieve bed to vibrate, so as to drive the first sieve mesh and the second sieve mesh to vibrate and screen the sediment.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, through the setting of the first sieve mesh and the second sieve mesh, the mesh numbers of the first sieve mesh and the second sieve mesh are the same. Therefore, when the first sieve mesh and the second sieve mesh overlap, they can effectively filter the sediment with larger particles. When the second sieve mesh is pulled by the electric push rod, it can be staggered from the first sieve mesh. Through the staggering, the mesh number of the sieve mesh can change. In this way, it can be effectively adjusted according to the size of different sediments without replacing the sieve mesh, so as to effectively achieve rapid screening according to different sediment sizes and improve the construction efficiency.

[0017] 2. In the present utility model, through the arrangement of the vibration motor, the vibration motor can effectively drive the sieve bed to vibrate. Through vibration, the sediment entering from the hopper can be effectively screened, and during the screening process, transportation can be carried out, thus effectively performing the screening work. And through the damping springs, the influence of vibration on the support columns can be effectively reduced, thereby effectively ensuring the stability of the support columns, the bottom frame, and the support feet, so that the screening work can be more stable.
