Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, specifically to an ore screening device. Background Technology

[0002] Ore screening is a crucial step in the ore processing, primarily used to classify ores of different particle sizes for subsequent processing. In traditional ore screening equipment, ore is typically screened using a vibrating screen.

[0003] However, existing vibrating screens have a significant problem when feeding ore: when the ore falls into the screen from a height, the impact force is large, which can easily cause direct mechanical damage to the screen, resulting in a shortened service life of the screen. This not only increases the maintenance cost of the equipment, but also affects the screening efficiency and production continuity.

[0004] Therefore, we propose an ore screening device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, this utility model provides an ore screening equipment, which has the advantages of installing a buffer plate at the feed port to reduce the direct impact of ore on the filter screen and improve the service life of the vibrating screen, and can effectively solve the problems in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an ore screening device, including a vibrating screener, wherein an ore feeding buffer structure is provided on the upper part of one end of the inlet of the vibrating screener, and a frame is fixedly installed on the lower outer surface of the vibrating screener. The ore feeding buffer structure includes a rectangular frame, a flared feed hopper, a rectangular ring base, a ring, a rectangular mounting groove, a damper, a compression spring, a first buffer guide plate and a second buffer guide plate, and the rear end of the lower outer surface of the rectangular ring base is welded to the rear end of the upper outer surface of the frame.

[0009] Preferably, the flared feed hopper is welded to the upper outer surface of the rectangular frame.

[0010] Preferably, the first buffer guide plate is fixedly installed on the upper left side of the inner cavity of the rectangular frame, and the second buffer guide plate is fixedly installed on the lower right side of the inner cavity of the rectangular frame.

[0011] Preferably, the ring body is fixedly installed on the upper outer surface of the rectangular ring base, the rectangular mounting groove is opened on the lower outer surface of the rectangular frame, and the upper part of the ring body extends into the rectangular mounting groove, and the outer wall of the ring body and the rectangular mounting groove are slidably connected.

[0012] Preferably, the damper and the compression spring are both located at the upper part of the rectangular mounting groove. The damper is fixed at equal intervals on the upper outer surface of the ring body, and the upper outer surface of the damper is fixedly connected to the upper part of the rectangular mounting groove. The compression spring is movably sleeved on the outer wall of the damper. The lower outer surface of the compression spring is fixedly connected to the upper outer surface of the ring body, and the upper outer surface of the compression spring is fixedly connected to the upper part of the rectangular mounting groove.

[0013] Preferably, the upper outer surface of the ring is elastically connected to the upper end of the rectangular mounting groove via a damper and a compression spring.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an ore screening device with the following advantages:

[0016] 1. This ore screening equipment reduces the direct impact of ore on the screen. By setting an ore feed buffer structure at the feed inlet of the vibrating screen, the ore passes through the buffer and guidance of the first buffer guide plate and the second buffer guide plate before entering the screen, which effectively reduces the direct impact of ore on the screen, reduces the wear and damage risk of the screen, and thus extends the service life of the vibrating screen.

[0017] 2. In this ore screening equipment, a damper and a compression spring are installed in the ore feed buffer structure. When the ore hits the buffer guide plate, the rectangular frame will descend and the ring will slide along the rectangular mounting groove, squeezing the damper and compression spring, which will further play a buffering role. This not only reduces the impact force of the ore, but also protects the ore feed buffer structure itself and improves the overall durability of the equipment.

[0018] 3. This ore screening equipment improves the stability of equipment operation. Through the elastic connection of the damper and the compression spring, the ore feed buffer structure can achieve local buffering and stress relief when receiving materials, reducing the vibration and impact of the equipment during operation and improving the stability and reliability of the equipment operation.

[0019] 4. This type of ore screening equipment reduces maintenance costs. Because the impact of ore on the screen is effectively mitigated, the frequency of screen wear and damage is greatly reduced, thus reducing the number of times equipment maintenance and screen replacement are required, thereby reducing maintenance costs and production downtime.
