Description

Technical Field

[0001] This utility model relates to the field of building material production technology, and in particular to a ceramsite sand screening device. Background Technology

[0002] In industrial production, ceramsite sand plays a crucial role as a key industrial raw material. It is a type of ceramic particle; finer particles are called sand, and it is also known as a proppant in oil fracturing. It has wide applications in the construction industry. Because different applications have strict requirements for the particle size classification of ceramsite sand, accurate screening is essential. The gyratory screen, with its superior performance, effectively meets the diverse screening needs of ceramsite sand.

[0003] However, existing gyratory screens have significant shortcomings in their screen installation methods. Common installation methods rely on numerous fasteners, such as screws and nuts. These parts are numerous and scattered, requiring operators to tighten them one by one during installation—a time-consuming process that drastically reduces equipment assembly efficiency. When the screen becomes clogged due to material residue after prolonged use and requires cleaning and maintenance, the complex installation structure significantly increases the difficulty of disassembly. Operators not only spend considerable time unscrewing numerous fasteners, but also require specialized tools to remove screws in concealed locations. In actual production processes, equipment downtime is closely related to economic losses; every minute of downtime can result in significant economic losses. The cumbersome screen disassembly and cleaning process keeps the equipment in a downtime state for extended periods, leading to production delays, untimely completion of production tasks, and severely impacting the company's economic benefits and market competitiveness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ceramic aggregate screening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ceramsite sand screening device includes two support plates, with a screening frame connected between the two support plates via a connecting mechanism. A screen is mounted on the screening frame via an installation groove. A drive motor is mounted on one of the support plates via a support frame, and the drive motor is connected to the screening frame via a connecting mechanism. The bottom of the screen has a moving groove, and both outer walls of the screen have receiving grooves. The screen has an internal movable cavity, which is connected to the receiving groove via a connecting cavity. A movable block is located within the movable cavity. A moving frame connected to the movable block is located within the moving groove via an external elastic mechanism. A positioning block is located within the receiving groove via an internal elastic mechanism, and the positioning block engages with the movable block via a contact mechanism. A positioning groove corresponding to the positioning block is located on the inner wall of the installation groove.

[0007] Preferably, the connecting mechanism includes a connecting frame fixedly installed on the screening rack, and the support plate is provided with a connecting groove corresponding to the connecting frame.

[0008] Preferably, the connecting mechanism includes a turntable mounted on the output shaft of a drive motor, a connecting frame eccentrically mounted on the turntable, a fixing block fixedly mounted on the screening rack, and the connecting frame rotatably connected to the fixing block.

[0009] Preferably, the external elastic mechanism includes an external spring disposed in the actuation groove, the external spring being sleeved on the outside of the actuation frame rod, and the two ends of the external spring being connected to the outer wall of the actuation frame head and the inner wall of the actuation groove, respectively.

[0010] Preferably, the internal elastic mechanism includes an internal spring disposed in the storage groove, with both ends of the internal spring connected to the outer wall of the positioning block and the inner wall of the storage groove, respectively.

[0011] Preferably, the contact mechanism includes a contact block disposed within the movable cavity and connected to the connecting rod, wherein the surfaces of the contact block and the movable block are inclined.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the cooperation of the connecting and linking mechanisms, the screening frame moves in three dimensions. Compared with the traditional screening device that moves in one direction, it can make the movement trajectory of the ceramsite sand on the screen more complex and comprehensive, thereby improving screening efficiency and accuracy.

[0014] 2. It is equipped with a unique external elastic mechanism, internal elastic mechanism and contact mechanism. When the screen mesh is severely clogged, the screen can be easily disassembled by moving the actuating frame, which facilitates the cleaning and maintenance of the screen and saves time and labor costs.

[0015] 3. The outer spring ensures the stability of the position of the actuating frame and the movable block, while the inner spring drives the relevant components to move when the movable block moves, ensuring that all components of the equipment remain stable under normal working conditions and reducing the occurrence of failures.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A ceramsite sand screening device includes two support plates 1, a screening frame 2 connected between the two support plates 1 by a connecting mechanism, a screen 4 mounted on the screening frame 2 by a mounting groove 3, a drive motor 6 mounted on one of the support plates 1 by a support frame 5, the drive motor 6 being connected to the screening frame 2 by a connecting mechanism, a turning groove 12 at the bottom of the screen 4, a receiving groove 20 on both outer walls of the screen 4, a movable cavity 15 inside the screen 4, the movable cavity 15 being connected to the receiving groove 20 by a connecting cavity 18, a movable block 16 inside the movable cavity 15, a turning frame 13 connected to the movable block 16 inside the turning groove 12 by an external elastic mechanism, a positioning block 21 inside the receiving groove 20 by an internal elastic mechanism, the positioning block 21 engaging with the movable block 16 by a contact mechanism, and a positioning groove corresponding to the positioning block 21 on the inner wall of the mounting groove 3.

[0024] The connecting mechanism includes a connecting frame 11 fixedly installed on the screening rack 2, and a connecting groove 10 corresponding to the connecting frame 11 is provided on the support plate 1. Both the connecting frame 11 and the connecting groove 10 are T-shaped, and the internal space of the connecting groove 10 is larger than that of the connecting frame 11, so that the connecting frame 11 can move in three dimensions within the connecting groove 10, since the screening rack 2 as a whole is in three-dimensional motion.

[0025] The connecting mechanism includes a turntable 7 mounted on the output shaft of the drive motor 6, a connecting frame 8 eccentrically mounted on the turntable 7, and a fixing block 9 fixedly mounted on the screening frame 2. The connecting frame 8 and the fixing block 9 are rotatably connected. The above components work together to enable the screening frame 2 to move in three dimensions after the drive motor 6 is started, thereby completing the swing screening.

[0026] The external elastic mechanism includes an external spring 14 disposed within the actuation groove 12. The external spring 14 is sleeved on the outside of the rod portion of the actuation frame 13, and its two ends are respectively connected to the outer wall of the head of the actuation frame 13 and the inner wall of the actuation groove 12. The elastic potential energy provided by the external spring 14 ensures that the actuation frame 13 remains stable in position when no external force is involved, thereby ensuring the stability of the position of the movable block 16 within the movable cavity 15.

[0027] The internal elastic mechanism includes an inner spring 22 disposed within the storage groove 20. The two ends of the inner spring 22 are connected to the outer wall of the positioning block 21 and the inner wall of the storage groove 20, respectively. The elastic potential energy provided by the inner spring 22 can cause the contact block 16, the connecting rod 19, and the positioning block 21 to move in the same way after the movable block 16 moves.

[0028] The contact mechanism includes a contact block 17 disposed within the movable cavity 15 and connected to the connecting rod 19. The surfaces of the contact block 17 and the movable block 16 are inclined. Due to the inclined arrangement, after the movable block 16 moves, the contact block 17, the connecting rod 19, and the positioning block 21 can move under the action of the inner spring 22.

[0029] When this utility model is in use, after the drive motor 6 is started, it can drive the screening frame 2 and the screen 4 to move in three dimensions between the two support plates 1 with the help of the turntable 7, the connecting frame 8 and the fixing block 9, so as to complete the swing screening operation of the ceramsite sand.

[0030] In this solution, when the mesh of the screen 4 is severely clogged and needs to be disassembled, the movable actuating frame 13 in the movable actuating groove 12 can be moved to move the movable block 16 in the movable cavity 15 and stretch the outer spring 14. Since the movable block 16 has moved, the contact block 17 will also move and the two contact blocks 17 will move closer (the inner spring 22 will be reset). Therefore, the positioning block 21 will move synchronously with the movable block 16 and the connecting rod 19. Thus, the positioning block 21 will disengage from the positioning groove on the inner wall of the mounting groove 3. When the positioning block 21 is completely disengaged from the positioning groove, the screen 4 loses its limiting installation and can be moved to be pulled out of the mounting groove 3. This completes the installation of the screen 4, and it is easier to process it after disassembly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
