Description

Technical Field

[0001] This utility model relates to the field of marine mineral material pretreatment technology, and in particular to a shell removal device for sea sand. Background Technology

[0002] Sea sand, as an important building aggregate resource, is increasingly widely developed and utilized. However, sea sand generally contains a large number of shells and fragments of various shapes and sizes, which brings significant engineering hazards. Shells have smooth surfaces, low water absorption, poor adhesion to cement paste, and are brittle and hard. If mixed into concrete, shells will seriously weaken the compressive strength, flexural strength, and durability of the concrete. Especially when the content is excessive, it can easily lead to cracks, spalling, or even failure of the concrete structure.

[0003] Current sea sand and shell removal devices mostly employ a single-stage screening structure, which often results in insufficient screening precision. Due to the significant size difference between sand particles and shells, some larger shells can be effectively removed through single-stage screening, but the shells are also prone to breakage during the process. These broken shells easily pass through the single-stage screen and mix with the screened sea sand, making it difficult to achieve the required purity of the final sea sand.

[0004] To address the above issues, we have developed a shell removal device for sea sand. Utility Model Content

[0005] This utility model discloses a shell removal device for sea sand, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A shell removal device for sea sand, comprising: Container; A primary sieve plate, which is movably connected to the inside of the container; Connecting rods, which are symmetrically and fixedly connected to the primary sieve plate; A rotating ring is rotatably connected to the outside of the connecting rod; A fixing frame, wherein the fixing frame is configured as a U-shaped structure and is symmetrically fixedly connected to the outside of the container; A sliding sleeve, which is slidably connected to the outside of the fixed frame; A sliding toothed plate is fixedly connected to the outside of the sliding sleeve. The sliding toothed plate has a V-shaped adjustment groove, and the rotating ring is tumbledly connected to the adjustment groove.

[0007] In a preferred embodiment, a rotating shaft is rotatably connected to the container, both ends of which extend to the outside of the container and are fixedly connected to a rotating plate. The outer side of the rotating plate is provided with a toothed structure that cooperates with a sliding toothed plate.

[0008] In a preferred embodiment, four sliding grooves are symmetrically formed on the outer side of the container, and the connecting rod is provided with protrusions that cooperate with the sliding grooves. In a preferred embodiment, the outer side of the container is symmetrically and fixedly connected with four support legs.

[0009] In a preferred embodiment, a mounting plate is fixedly connected between the outer sides of the two legs, and a drive motor is fixedly connected to the outer side of the mounting plate. The output end of the drive motor is connected to a rotating shaft.

[0010] In a preferred embodiment, a stirring paddle is fixedly connected at equal intervals to the outside of the rotating shaft and inside the container.

[0011] In a preferred embodiment, a secondary sieve plate is rotatably connected between the two rotating plates.

[0012] The shell removal device in sea sand provided by this utility model has the following advantages: This device transmits power from a drive motor to a sliding toothed plate via a rotating shaft, rotating plate, and its toothed structure. The adjustment grooves on the V-shaped structure of the sliding toothed plate, in conjunction with the rotating ring, drive the primary screen plate to vibrate and screen vertically. Below the primary screen plate, a secondary screen plate, driven by a rotating plate, is installed, achieving multi-stage screening through oscillation. Compared to traditional single-stage screening devices, this device offers finer screening, better grading, and effectively handles shell fragments and sand particles of different sizes, thus improving the purity of the final sea sand.

The sliding toothed plate 7 has a V-shaped adjustment groove 8, and the rotating ring 4 is tumbledly connected to the adjustment groove 8. In this embodiment: when the sliding toothed plate 7 moves left and right, the rotating ring 4 will reciprocate along the adjustment groove 8 of the V-shaped structure, thereby driving the connecting rod 3 to move up and down, and then driving the primary screen plate 2 to move up and down in the holding tank 1 to achieve a vibration effect, thereby realizing the screening of sea sand and the initial separation of shells.

[0022] Reference Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, in a preferred embodiment, a rotating shaft 9 is rotatably connected to the container 1. Both ends of the rotating shaft 9 extend to the outside of the container 1 and are fixedly connected to a rotating plate 10. The outer side of the rotating plate 10 is provided with a tooth structure that cooperates with the sliding toothed plate 7. In this embodiment, the rotating shaft 9 drives the rotating plates 10 fixed at both ends to rotate synchronously. The toothed structure on the outer side of the rotating plate 10 meshes with the sliding toothed plate 7. When the rotating plate 10 rotates, its toothed structure drives the sliding toothed plate 7 that meshes with it to move left and right, providing a power source for the vibration of the primary screen plate 2.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, four sliding grooves 11 are symmetrically provided on the outer side of the container 1, and the connecting rod 3 is provided with protrusions that cooperate with the sliding grooves 11. In this embodiment, the protrusion on the connecting rod 3 is embedded in the sliding groove 11 on the outside of the container 1. When the connecting rod 3 is driven to move by the rotating ring 4, the protrusion slides in the sliding groove 11. The sliding groove 11 plays a guiding and limiting role to prevent swaying.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, four support legs 16 are symmetrically fixed to the outer side of the container 1; In this embodiment, four support legs 16 are fixedly connected to the lower outer side of the container 1 to support the entire shell removal device and place it stably on the working surface.

The output end of the drive motor 13 is connected to the rotating shaft 9. In this embodiment: the drive motor 13 drives the rotating shaft 9 to rotate in both forward and reverse directions.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, a stirring paddle 14 is fixedly connected at equal intervals to the outside of the rotating shaft 9 and inside the container 1. In this embodiment: when the drive motor 13 drives the rotating shaft 9 to rotate, the stirring paddle 14 fixed on it rotates synchronously in the holding tank 1. The stirring paddle 14 stirs the sea sand mixture in the tank, so that the sand particles and shells can be fully rolled and collided, which helps to break up the sticky sand blocks, disperse the clumps of shells, and promote the separation of shell fragments from sand particles, thereby improving screening efficiency.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, a secondary sieve plate 15 is rotatably connected between the two rotating plates 10; In this embodiment: when the rotating plate 10 is driven to rotate by the rotating shaft 9, it will cause the secondary screen plate 15 to swing inside the holding tank 1. The secondary screen plate 15 can achieve the screening effect by swinging. The material after being initially screened by the primary screen plate 2 falls onto the secondary screen plate 15, and the swinging motion is used for finer screening to achieve a multi-stage screening effect.
