Description

Technical Field

[0001] This utility model belongs to the field of screening equipment, and in particular relates to an environmentally friendly modular combined vibrating screen. Background Technology

[0002] In existing technologies, vibrating screens are commonly used for grading large materials in industries such as ore, coal, and metallurgy. Vibrating screens are typically installed below silos. Since they cannot directly withstand the silo pressure, a feeder is required between the vibrating screen and the silo. The feeder can withstand the silo pressure when the machine is stopped, and plays a role in evenly distributing the material during operation. However, with increasingly stringent environmental protection requirements, all interfaces between equipment must be completely sealed to prevent dust leakage.

[0003] Traditionally, vibrating screens and feeders are installed independently, resulting in a large number of devices and interfaces, which increases the probability of dust leakage. The interfaces between devices are particularly prone to dust leakage and are the most difficult to seal completely. Furthermore, independently installed vibrating screens and feeders occupy a significant amount of space, leading to higher infrastructure costs.

[0004] Several invention patents have been developed to address issues such as dust leakage, high noise levels, and low screening efficiency in vibrating screening equipment during the screening process. For example:

[0005] Patent CN113649267A discloses a high-efficiency and environmentally friendly self-cleaning screen, which features a semi-enclosed dust cover above the screen frame and at the discharge end. The dust cover is sealed to the side plate of the screen frame using a flexible connection. Although this patent employs a dust cover and a flexible connection sealing structure, it still suffers from poor dust prevention. Utility Model Content

[0006] To address the problem of dust leakage caused by the large number of interfaces in existing equipment, this utility model proposes a combined environmentally friendly modular screen, comprising: a feed inlet flexible connection, a feed inlet, a feeder, a screen frame, a screen plate, a screen holder, a housing, and a vibrator. The feeder trough, the screen frame, and the screen plate are disposed inside the housing, while the screen holder, spring seat, spring, feeder vibration motor, and vibrator motor are disposed outside the housing.

[0007] As an improvement to the above solution, each side of the feeder trough has an independent vibrating motor as a power source, and the screen frame and screen plate at the front are powered by a vibrator.

[0008] As an improvement to the above solution, the feed inlet guide chute is connected to the outer casing inlet flange via a rubber flexible connection; the vibrator is connected to the screen frame and passes through the rubber flexible connection on the outer casing to connect to the screen frame; the vibrating motor of the feeder is sealed with a special sealing body, and the connection with the outer casing is sealed via a flexible connection; the entire screening operation is carried out in a fully sealed state.

[0009] As an improvement to the above solution, the feed inlet is fastened to the upper hopper flange with bolts, and a gap is left between it and the outer shell so that the feeder will not collide with the outer shell during operation.

[0010] As an improvement to the above solution, the feed inlet is sealed by a flexible connection to prevent dust from being kicked up by the feeder from leaking out.

[0011] As an improvement to the above solution, the feeder vibrating motor and the trough are sealed by a special sealing body, the screen frame and the vibrator are also sealed by a rubber flexible connection, and rubber seals are provided at the material outlets under and over the screen.

[0012] As an improvement to the above solution, the inlet and outlet ports, as well as all seals between the maintenance and internal parts, are made of soft rubber seals.

[0013] As an improvement to the above solution, the environmental protection modular screen also includes an air inlet, which draws a small amount of air into the screen body, so that the entire system operates under negative pressure.

[0014] Compared with existing technologies, the combined environmentally friendly modular screen provided by this utility model organically combines a feeder and a vibrating screen into one device, reducing the number of devices and interfaces, lowering the probability of dust leakage, and solving the problems of numerous devices, numerous interfaces, and high probability of dust leakage in existing technologies. This combined environmentally friendly modular screen has a small footprint, reducing infrastructure costs, and solving the problems of large space occupation and high infrastructure costs associated with independently set vibrating screens and feeders in existing technologies. This combined environmentally friendly modular screen adopts a rubber flexible connection sealing structure, which has excellent sealing performance and can effectively prevent dust leakage, solving the problem of poor dust prevention effect of dust covers and flexible connection sealing structures in existing technologies. This combined environmentally friendly modular screen places the vibrating components inside the outer shell, which can effectively reduce noise, and the vibrating components are lightweight, have a large amplitude, and high screening efficiency, solving the problems of high noise and low screening efficiency in existing vibrating screening equipment.

[0021] like Figure 1 , Figure 2As shown, the combined environmentally friendly modular screen of this embodiment includes a feed inlet flexible connection 1, a feed inlet 2, a feeder 3, a screen frame 4, a screen plate 5, a screen frame 6, a housing 7, and a vibrator 8. The feeder 3's trough, screen frame 4, and screen plate 5 are housed inside the housing 7, while the screen frame 6, spring seat, spring, feeder vibration motor, and vibrator 8 motor are housed outside the housing 7. Each side of the feeder 3's trough has an independent vibration motor as a power source, while the front screen frame 4 and screen plate 5 are powered by the vibrator 8. The feed inlet 2's guide trough is connected to the housing 7's inlet flange via a rubber flexible connection; the vibrator 8 is connected to the screen frame 4 and passes through the rubber flexible connection on the housing 7 to connect to the screen frame 6; the feeder 3's vibration motor is sealed with a special sealing body 9, and its connection to the housing 7 is sealed via a flexible connection; the entire screening operation is carried out in a fully sealed state. The feed inlet 2 is bolted to the upper-level hopper flange, leaving a gap with the housing 7 to prevent the feeder 3 from colliding with the housing 7 during operation. The feed inlet 2 is sealed by a flexible feed inlet connector 1 to prevent dust from the feeder 3 from leaking out. A special sealing body 9 seals the vibrating motor and the trough of the feeder 3, and a rubber flexible connector seals the screen frame 4 and the vibrator 8. Rubber seals are installed at both the under-screen and over-screen material outlets. All seals between the feed inlet / outlet and all maintenance / internal areas are made of rubber flexible seals. The environmentally friendly modular screen also includes an air inlet that draws a small amount of air into the screen body, ensuring the entire system operates under negative pressure.

[0022] like Figure 1As shown, the working principle of this utility model is that during operation, the screen frame and outer shell remain stationary, while the feeder, screen frame, screen plate, and vibration source vibrate. A flexible connection seals the vibrating body from the stationary body. When stopped, the feeder can withstand the silo pressure and prevent material from flowing out by gravity. Material in the upper silo pours downwards into the feeder at the inlet of the combined environmentally friendly modular screen. The feeder can withstand significant silo pressure and prevents material from continuing to flow forward when stopped. The feeder has two independent vibrating motors as its power source, while the screen frame and screen plate in front are powered by a vibrator. The feeder and screen frame / screen plate start and run simultaneously. The feed inlet is bolted to the flange of the upper silo, maintaining a sufficiently large gap with the outer shell to ensure that the feeder will not collide with it during operation. A flexible connection seals the outside of the feed inlet, preventing dust raised by the feeder from leaking out. The vibrating screen's outer shell and hopper are integrated. The vibration source and springs are located outside the shell, while the rest are internal. A dedicated seal is used between the feeder's vibrating motor and the trough, and a dedicated rubber flexible connection seals between the screen frame and the vibration source. Both the under-screen and over-screen material outlets have dedicated rubber seals, preventing dust leakage. The feeder is housed within the outer shell, resulting in a high degree of integration. The outer shell and screen frame (chassis) do not participate in the vibration, ensuring static stability and minimizing dust leakage caused by vibration. Only the screen frame and screen plate vibrate, resulting in lightweight, large amplitude, and low energy consumption. Compared to traditional external feeders with vibrating screens, this design offers the same functionality, a compact structure, and a smaller footprint, reducing infrastructure costs. The inlet and outlet ports use double-sealed rubber materials for soft sealing. Rubber materials offer excellent sealing performance, withstand impact loads better than most elastomers, reduce noise, provide excellent sealing performance, and have a long service life. This reduces the number of interfaces and lowers the probability of dust leakage.

[0023] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
