Description

Technical Field

[0001] This utility model relates to the field of marine sand pretreatment technology, and in particular to a marine sand particle grading and sorting device. Background Technology

[0002] Sea sand, as an important construction resource, is often used as aggregate or filler material in concrete. In order to meet the strict requirements of different projects for aggregate particle size and to improve concrete performance, the mined sea sand must be graded and selected to remove excessively large or small particles in order to obtain sand with uniform particle size.

[0003] However, the structures of commonly used sea sand separation devices are often quite complex, which not only leads to maintenance difficulties, but also makes it difficult for some devices to achieve multi-stage synchronous and efficient sorting, resulting in poor control of particle size dispersion. In addition, the collection and separation of products of different particle size grades are often not convenient and effective, easily causing mixing or requiring additional manual intervention, thus affecting the overall sorting accuracy and operating efficiency.

[0004] To address the above issues, we have introduced a new type of sea sand particle grading and sorting device. Utility Model Content

[0005] This utility model discloses a device for classifying and refining sea sand particles, 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 sea sand particle grading and sorting device includes a housing. Inside the housing, fixed frames are fixedly connected at equal intervals. Vertical plates are symmetrically fixedly connected to each fixed frame. Sliding columns are fixedly connected to the sides of two adjacent vertical plates. A sliding plate is slidably connected between the two sliding columns. Filter screens are connected to both sides of the sliding plate by screws. The side of the filter screens away from the sliding plate is mounted on the top of the fixed frame by fixing pins. A crankshaft is rotatably connected inside the fixed frame, and the crankshaft abuts against the bottom of the sliding plate.

[0007] In a preferred embodiment, one end of each crankshaft extends to the outside of the housing and is connected to a mating wheel and a drive wheel corresponding to the number of mating wheels.

[0008] In a preferred embodiment, a mounting bracket is fixedly connected to the outer side of the housing, and a drive motor is fixedly mounted on the mounting bracket. The drive motor is connected to the corresponding crankshaft.

[0009] In a preferred embodiment, a container is slidably connected inside the box.

[0010] In a preferred embodiment, slots are provided at equal intervals on both sides of the box body, and an extension plate is fixedly connected to the outer side of the box body and below the slots.

[0011] In a preferred embodiment, a transmission belt is provided between the mating wheel and the drive wheel.

[0012] In a preferred embodiment, the outer side of the container is provided with a handle.

[0013] The sea sand particle grading and sorting device provided by this utility model has the following advantages: This invention achieves efficient and stable reciprocating linear vibration of the sliding plate and its filter screen by setting a crankshaft driven by a drive motor to abut against the bottom of the sliding plate. The crankshaft rotation is directly converted into vibration screening of the sliding plate and its filter screen. By setting multiple layers of filter screens with different pore sizes for vibration screening, the sea sand particles are sorted into multiple levels of high efficiency according to particle size. Through the slot and the extension plate below it, particles of different particle sizes that cannot pass through the sieve are automatically discharged and effectively guided to the designated collection position, thus achieving the effect of graded collection of sea sand particles.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] This utility model discloses a device for classifying and refining sea sand particles.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a sea sand particle grading and sorting device includes a box body 1. Inside the box body 1, fixed frames 2 are fixedly connected at equal intervals. Vertical plates 3 are symmetrically fixedly connected to each fixed frame 2. Sliding columns 4 are fixedly connected to the side of the two vertical plates 3 that are close to each other. A sliding plate 5 is slidably connected between the two sliding columns 4. Filter screens 6 are connected to both sides of the sliding plate 5 by screws. The side of the filter screen 6 away from the sliding plate 5 is installed on the top of the fixed frame 2 by fixing pins 7. A crankshaft 8 is rotatably connected inside the fixed frame 2. The crankshaft 8 abuts against the bottom of the sliding plate 5. In this embodiment, when the crankshaft 8 rotates, its eccentric profile periodically pushes the bottom of the sliding plate 5 upward, causing the sliding plate 5 to slide upward along the sliding column 4. When the lowest point of the eccentric profile of the crankshaft 8 rotates to contact the sliding plate 5, the sliding plate 5 slides downward along the sliding column 4 to reset under the action of gravity. This process repeats, causing the sliding plate 5 and the filter screen 6 on it to reciprocate in the vertical direction.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, one end of each crankshaft 8 extends to the outside of the housing 1 and is respectively connected to a mating wheel 9 and a drive wheel 10 corresponding to the number of mating wheels 9; In this embodiment, the mating wheel 9 and the drive wheel 10 connected to the end of the crankshaft 8 extending to the outside of the housing 1 transmit external power to the interface of the crankshaft 8. The drive wheel 10 receives the power input and transmits the rotational motion through the crankshaft 8 connected to it, driving the crankshaft 8 to rotate. The mating wheel 9 is used to realize the linkage drive of multiple crankshafts 8.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a mounting bracket 12 is fixedly connected to the outside of the housing 1, and a drive motor 13 is fixedly mounted on the mounting bracket 12. The drive motor 13 is connected to the corresponding crankshaft 8. In this embodiment, the drive motor 13 fixed on the mounting bracket 12 serves as a power source, and its output shaft is directly connected to the corresponding crankshaft 8. When the drive motor 13 starts, the rotational torque it generates directly drives the crankshaft 8 to rotate, thereby providing the core power for the vibration of the sliding plate 5 and the filter screen 6.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a container 14 is slidably connected inside the housing 1; In this embodiment, the holding box 14 is located below the filter screen 6 and can be slidably pulled out or pushed in along the internal track of the box body 1. Its function is to receive and collect the sea sand particles that have passed through the finest layer of filter screen 6 after being vibrated and screened by the upper multi-layer filter screen 6, so as to facilitate centralized processing and transportation.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, slots 16 are provided at equal intervals on both sides of the box body 1, and extension plates 17 are fixedly connected to the outer side of the box body 1 and below the slots 16. In this embodiment: when the filter screen 6 vibrates and screens, sea sand particles with a diameter larger than the pore size of the filter screen 6 will gradually move towards the edge of the filter screen 6 under the action of vibration, and finally be discharged from the box 1 through the corresponding slot 16. The extension plate 17 fixed below the slot 16 plays the role of guiding and receiving, guiding the sea sand particles of different particle sizes discharged from the slot 16 to the designated collection area or container, so as to realize the separation and collection of multi-stage sorting products.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a transmission belt 11 is provided between the mating wheel 9 and the drive wheel 10; In this embodiment: when the drive motor 13 drives the drive wheel 10 directly connected to it to rotate, the power is transmitted to the mating wheel 9 through the friction transmission action of the transmission belt 11, thereby driving the other crankshaft 8 connected to the mating wheel 9 to rotate synchronously.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a handle 15 is provided on the outside of the container 14; In this embodiment, the handle 15 installed on the outside of the container 14 is convenient for the operator to hold. When it is necessary to take out the fine sand collected in the container 14 or to clean and maintain it, the operator only needs to hold the handle 15 to easily pull the container 14 out along the working position inside the box 1. The operation is convenient and labor-saving.

[0030] Working principle: When this device is working, the drive motor 13 drives the crankshaft 8 directly connected to it to rotate. The crankshaft 8 extends to the drive wheel 10 connected to the outside of the housing 1 at one end. The power is transmitted to the mating wheel 9 at the end of other crankshafts 8 via the transmission belt 11, thereby realizing the synchronous rotation of multiple crankshafts 8. The rotating crankshaft 8 periodically pushes the bottom of the sliding plate 5 upward with its eccentric contour, so that the sliding plate 5 overcomes gravity and slides upward along the sliding column 4. When the lowest point of the eccentric contour of the crankshaft 8 rotates to the contact position, the sliding plate 5 slides downward along the sliding column 4 to reset under the action of gravity. This process is repeated, causing the filter screen 6 connected to the sliding plate 5 by screws to make continuous reciprocating vibration in the vertical direction.

[0031] The input sea sand is screened on multiple vibrating screens 6 with different pore sizes. Particles smaller than the current pore size of the screen 6 pass through the screen and fall down. The smallest selected sand falls into the bottom sliding collection box 14 for collection. Particles larger than the current pore size of the screen 6 gradually move to the edge under the vibration and are eventually discharged through the slots 16 on both sides of the box 1 at the corresponding level positions. They are then guided to the designated collection position by the extension plate 17 fixed below the slots 16, thus realizing the classification and selection of sea sand particles according to their size.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
