Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a modular vibrating screen. Background Technology

[0002] A vibrating screen is a circular vibrating screen with a screen box that moves in a circular motion. It operates by utilizing the vibration generated by the circular motion of a counterweight. The amplitude is adjusted by adding or removing counterweights, making the vibrating screen suitable for screening different materials. It features reliable structure, strong excitation force, high screening efficiency, durability, and easy maintenance. This type of vibrating screen is widely used in product grading in industries such as mining, building materials, transportation, and energy. It separates particles of different sizes through a screen mesh, and its vibration trajectory is circular or a near-circular curve, making it widely applicable across various industries.

[0003] In current industrial applications, the various components of a vibrating screen are primarily connected and fixed through welding. However, this welding method has some inherent problems. Because internal stress is generated near the weld point during the welding process, the material becomes brittle in these areas, making them prone to cracking at the weld point.

[0004] Furthermore, if a part of the vibrating screen is damaged and requires repair or replacement, the welded connections make the process quite difficult and time-consuming. This inconvenience not only increases maintenance costs but can also lead to a decrease in production efficiency, as replacing components requires more time and manpower. Therefore, while welding provides a certain degree of component fixation, it also introduces internal stress problems, inconvenience in repair and replacement, and increased production costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model discloses a modular vibrating screen, including a side plate assembly 1, a screening assembly 2 is provided on the inner side of the side plate assembly 1, and two sets of vibrators 3 are provided on the outer side of the side plate assembly 1, and the two sets of vibrators 3 are interconnected.

[0028] The side panel assembly 1 includes a first protective side panel 101 and a second protective side panel 102, which are located on both sides of the screening assembly 2.

[0029] The screening component 2 includes an upper screening frame 201, a middle screening frame 202, and a lower screening frame 203, which are located between the first protective side plate 101 and the second protective side plate 102.

[0030] Furthermore, to facilitate maintenance and screen replacement, the screens of the upper screening frame 201, middle screening frame 202, and lower screening frame 203 are all designed to be detachable, allowing for easy removal or replacement of the screens from the frames. This design not only reduces maintenance costs but also improves the flexibility and adaptability of the vibrating screen.

[0031] The upper screening frame 201 is provided with an upper baffle plate 204 and an upper discharge plate 207 at its front and rear ends, respectively. The middle screening frame 202 is provided with a middle baffle plate 205 and a middle discharge plate 208 at its front and rear ends, respectively. The lower screening frame 203 is provided with a lower baffle plate 206 and a lower discharge plate 209 at its front and rear ends, respectively.

[0032] The front sides of the upper baffle plate 204, the middle baffle plate 205 and the lower baffle plate 206 are connected to the feed ends of the upper screening frame 201, the middle screening frame 202 and the lower screening frame 203 by bolts.

[0033] The back sides of the upper discharge plate 207, the middle discharge plate 208, and the lower discharge plate 209 are connected to the discharge ends of the upper screening frame 201, the middle screening frame 202, and the lower screening frame 203 by bolts.

[0034] An assembly support beam 210 and a spring seat support beam 211 are provided between the first protective side plate 101 and the second protective side plate 102. An exciter 3 is provided on the side end of the assembly support beam 210, and a spring support 212 is provided on the side end of the spring seat support beam 211.

[0035] Furthermore, to further enhance the stability and durability of the vibrating screen, the assembly support beam 210 and spring seat support beam 211 are also made of high-strength materials, and their dimensional accuracy and surface finish are ensured through precision machining processes. This design not only improves the overall rigidity of the vibrating screen but also reduces noise and energy consumption caused by vibration.

[0036] This utility model provides a modular vibrating screen. Through its modular design, it enables the prefabrication and stacking of various components, effectively solving the problem of excessive space occupation during storage of traditional prefabricated vibrating screens. Simultaneously, by optimizing the design of the screening component 2 and the vibrator 3, the screening efficiency and accuracy of the vibrating screen are improved. Furthermore, the adoption of a detachable screen design reduces maintenance costs and enhances the flexibility and adaptability of the vibrating screen. Therefore, this utility model has broad application prospects and market value.

[0037] Specifically, the surfaces of the first protective side plate 101 and the second protective side plate 102 are provided with mounting holes 103 and connecting holes 104. The mounting holes 103 are located at the center of the first protective side plate 101 and the second protective side plate 102. The vibrator 3 is located inside the mounting holes 103, and the spring support 212 is located inside the connecting holes 104.

[0038] In this embodiment, the vibrator 3 is securely connected to the side plate assembly 1 via the mounting hole 103, ensuring that the vibrator 3 can stably provide vibration power during operation. Meanwhile, the spring support 212 is connected to the side plate assembly 1 via the connecting hole 104, providing support and cushioning, further enhancing the stability and durability of the vibrating screen.

[0039] Specifically, the filtering accuracy of the upper filtering frame 201, the middle filtering frame 202, and the lower filtering frame 203 gradually increases from top to bottom.

[0040] In this embodiment, to optimize the screening effect of the vibrating screen, the mesh size of the upper screening frame 201, the middle screening frame 202, and the lower screening frame 203 gradually decreases from top to bottom to achieve graded screening of particles of different sizes. This design enables the vibrating screen to separate particles of different sizes more efficiently during the screening process, improving screening efficiency and screening accuracy.

[0041] Specifically, the side ends of the upper baffle plate 204, the middle baffle plate 205 and the lower baffle plate 206 are respectively connected to the inner sides of the first protective side plate 101 and the second protective side plate 102 by bolts.

[0042] In this embodiment, the design of the upper baffle plate 204, the middle baffle plate 205, and the lower baffle plate 206 not only serves to block materials and prevent them from overflowing from the sides of the screening frame during the screening process, but also ensures the stability between the baffle plates and the protective side plates through bolt connections. This design makes it difficult for the baffle plates to loosen or fall off when the vibrating screen vibrates at high speed, thereby ensuring the continuity and stability of the screening process.

[0043] Specifically, the side ends of the upper discharge plate 207, the middle discharge plate 208 and the lower discharge plate 209 are respectively connected to the inner sides of the first protective side plate 101 and the second protective side plate 102 by bolts.

[0044] In this implementation plan, the design of the discharge plate also takes into account stability and practicality. Through bolt connection, the discharge plate can be securely installed at the end of the screening frame, ensuring that the screened material can be smoothly discharged from the discharge port.

[0045] When using the equipment, users can select different mesh sizes of screens and install them on the corresponding screening frame according to their actual screening needs.

[0046] The vibrating force generated by the vibrator 3 causes the upper screening frame 201, middle screening frame 202, and lower screening frame 203 to vibrate and screen. Material is fed into the vibrating screen from the top and first passes through the upper screening frame 201. Larger particles are blocked by the screen of the upper screening frame 201, while smaller particles continue to fall through the screen to the middle screening frame 202. In the middle screening frame 202, the material is screened again; medium-sized particles are blocked, while even smaller particles continue to fall to the lower screening frame 203. Finally, after screening by the lower screening frame 203, particles of different sizes are obtained and graded.

[0047] This causes the material to enter from the upper screening frame 201 and pass through the middle screening frame 202 and the lower screening frame 203, ultimately resulting in particles of different sizes.

[0048] Meanwhile, the upper baffle plate 204, the middle baffle plate 205 and the lower baffle plate 206 can prevent material particles from falling.

[0049] The angles and positions of the upper discharge plate 207, middle discharge plate 208, and lower discharge plate 209 can also be adjusted as needed to accommodate the discharge requirements of materials with different particle sizes. This design allows the vibrating screen to achieve optimal screening effect and discharge efficiency when screening different materials.

[0050] This grading and screening method not only improves screening efficiency but also ensures screening accuracy, enabling vibrating screens to perform at their best in various applications.

[0051] Furthermore, this modular vibrating screen is easy to maintain and replace. When the screen wears out or needs replacement, users can simply remove it from the frame and install a new screen. This design not only reduces maintenance costs but also improves the flexibility and adaptability of the vibrating screen, enabling it to better meet the screening needs of different users.

[0052] In summary, this modular vibrating screen constructs its structure by connecting its various components using rivets or bolts. This design allows the components to be prefabricated before assembly and stacked together, resulting in a very small space footprint in the unassembled state. This prefabrication and stacking method brings great convenience during production, equipment adjustment, and maintenance. It effectively solves the problem of excessive space occupation when storing traditional prefabricated vibrating screens, thus significantly improving the space utilization rate of the workshop.
