Description

A multi-layer screening device that is easy to clean Technical Field

[0001] This utility model belongs to the field of multi-layer screening devices, specifically, it relates to a multi-layer screening device that is easy to clean. Background Technology

[0002] Screening devices are equipment used to screen and classify mixed materials according to particle size or shape. They are widely used in feed processing, agricultural product sorting, chemical pellet processing, building material screening, and many other fields. Depending on the application requirements, screening devices are usually divided into single-layer screening and multi-layer screening, among others. Multi-layer screening devices can perform multiple stages of screening simultaneously, greatly improving material processing efficiency and screening accuracy, and have become an indispensable basic equipment in modern processing industries.

[0003] Existing multi-layer screening devices mainly consist of a screen body, screen mesh, and vibrating mechanism. They typically use multiple parallel screens to classify and screen materials, relying on a vibrating motor to drive the entire screen body to vibrate, thus causing the material to move across the screen mesh. While these devices perform well in terms of screening efficiency, their structural design generally suffers from problems such as inconvenient cleaning, complex disassembly and assembly, and difficulty in replacing screen mesh. Especially during continuous operation, fine particles or impurities easily accumulate on the screen mesh. If not cleaned promptly, this not only affects the screening effect but also shortens the equipment's lifespan. Furthermore, the tightly assembled screen plates require layer-by-layer disassembly for cleaning or replacement, resulting in high labor intensity, complex operation, and reduced practicality and maintenance efficiency.

[0004] In view of this, this utility model is proposed. Summary of the Invention

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please refer to Figures 1-4. In this embodiment, a multi-layer screening device that is easy to clean is provided, including a box 1. A plurality of discharge boxes 2 are connected to one side of the box 1. The discharge boxes 2 are connected to the box 1 in sequence. An installation frame 3 is fixedly connected to the other side of the box 1. A filter assembly is provided inside the installation frame 3. The filter assembly includes a plate 4 located inside the installation frame 3. A plurality of filter plates 5 corresponding to the positions of the discharge plates are connected to one side of the plate 4. The number of filter holes in each filter plate 5 decreases from top to bottom. Vibration motors 6 are fixedly connected to both sides of the outer wall of the box 1. A connecting frame 7 is clamped on the top of the box 1. The connecting frame 7 and the plate 4 are clamped together.

[0026] This utility model employs a housing 1 connected to multiple discharge boxes 2. A filter assembly and mounting frame 3 are located on one side of the housing 1. The filter assembly uses multiple filter plates 5 with progressively smaller filter holes for graded screening. The plates 4 and the connecting frame 7 can be quickly snapped together, significantly improving assembly and disassembly efficiency. A vibration motor 6 enhances material flowability, and the detachable connection design allows for the complete extraction and simultaneous cleaning of the filter assembly, avoiding the tedious process of disassembling each screen plate individually in traditional devices, thus saving labor costs.

[0027] In this embodiment, both side walls of the discharge box 2 are sloping structures, the ends of the discharge box 2 are rounded structures, and a discharge pipe 8 is provided below the discharge box 2. The sloping structure facilitates the material to fall from the discharge pipe 8 along the extended slope.

[0028] In this embodiment, a first combined plate 9 is fixedly connected to the upper part of both sides of the outer wall of the housing 1, and a second combined plate 10 corresponding to the position of the first combined plate 9 is fixedly connected to the lower part of both sides of the connecting frame 7. A guide rod 11 is fixedly connected to the upper part of the first combined plate 9, and a guide hole adapted to the guide rod 11 is opened on the upper part of the second combined plate 10. When the mounting frame 3 is installed, the guide rod 11 can be accurately inserted into the guide hole, thereby initially positioning the mounting frame 3. This structure not only simplifies the installation process and avoids repeated adjustments due to inaccurate manual alignment, but also stabilizes the position of the mounting frame 3 before subsequent fixed connection, improving assembly accuracy and efficiency. For users, installation can be completed quickly without the need for additional auxiliary tools, effectively reducing operational difficulty and enhancing the operability and maintenance convenience of the device.

[0029] In this embodiment, a connecting strip 12 is fixedly connected to one side of the plate 4, and a guide post 1311 is fixedly connected to the side of the connecting strip 12 facing the vibration motor 6. A positioning plate 14 is fixedly connected to the top of the connecting frame 7. A first threaded hole is opened in the vertical direction of the positioning plate 14, and a screw 15 is threadedly connected inside the first threaded hole. A threaded groove matching the screw 15 is opened on the circumference of the outer wall of the guide post 13. In this utility model, the screw 15 passes through the first threaded hole on the positioning plate 14 and matches the threaded groove on the outer wall of the guide post 13 on the connecting strip 12. By rotating the screw 15, the position of the connecting strip 12 can be locked, thereby stabilizing the installation position of the entire plate 4 in the mounting frame 3. This structure is simple in design and easy to adjust. Only two screws 15 are needed to complete the fixing operation between the plate 4 and the connecting frame 7 at the same time, eliminating the cumbersome multi-point fixing steps and significantly improving assembly efficiency. Meanwhile, when it is necessary to disassemble, clean or replace the plate 4 in the later stage, it can be quickly released by simply loosening the two screws 15, which greatly facilitates the maintenance and upkeep of the equipment.

[0030] In this embodiment, a crank handle 16 is fixedly connected to the upper end of the screw 15 for easy access. Support rods 17 are fixedly connected to the four lower corners of the housing 1. The length of the support rod 17 at the first edge of the housing 1 is shorter than the length of the support rod 17 at the second edge of the housing 1, causing the housing 1 to be tilted. By setting the housing 1 in a tilted structure with a lower front and higher back, the screened feed particles can naturally slide down into the discharge box 2 near the lower end under gravity during use. Compared to a horizontal structure, this tilted layout effectively reduces material residue in the housing 1, avoids blockage problems caused by material accumulation or retention, and helps improve discharge efficiency.

[0031] In this embodiment, a through hole 18 is provided on one side of the plate 4, and a second threaded hole corresponding to the position of the through hole 18 is provided on one side of the filter plate 5. A bolt threaded into the second threaded hole is inserted into the through hole 18. In this utility model, the plate 4 and multiple filter plates 5 are connected by bolts. This structure can not only firmly fix each filter plate 5, preventing it from loosening or shifting during the screening process and ensuring screening accuracy; at the same time, when the device needs to be cleaned or the filter plates 5 replaced, the operator only needs to unscrew the bolts to remove the plate 4 and multiple filter plates 5 as a whole from the mounting frame 3. Compared with the traditional method of disassembling one by one, this structure can realize the simultaneous removal of multiple filter plates 5, which greatly improves the disassembly and assembly efficiency, facilitates the comprehensive cleaning of the filter plates 5 and the inside of the housing 1, reduces cleaning dead corners, and effectively improves the service life and maintenance convenience of the equipment.

[0032] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
