Abstract
Description
Technical Field
[0001] The utility model relates to the field of mineral processing equipment, in particular to a vibrating screen feeding device. Background Art
[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art with respect to the technical solution of the present application.
[0003] In the prior art, vibrating screens usually adopt a centralized feeding method, and the discharge of ore from the upper process to the vibrating screen is mostly done through circular pipes. This method has many problems. In the pipeline discharge method, the slurry is discharged from the pipe at high speed, directly impacting the screen of the vibrating screen, causing the screen to be subjected to a large impact force, local overload of the vibrating screen, and easy damage to the screen surface. Frequent replacement of the screen not only increases production costs, but also affects the continuity of production. Centralized feeding through pipes makes the feed distribution of the vibrating screen uneven. In some areas, the slurry flow is large, which easily causes the screen to be clogged; while in other areas, the slurry flow is small, and the screening efficiency is low. Uneven feeding will also cause uneven force on the vibrating screen, affecting the stability and service life of the equipment. At the same time, when repairing the vibrating screen, the vibrating screen and the feeding pipe interfere with each other, and the vibrating screen cannot be lifted quickly, which is time-consuming and labor-intensive.

When the position locking device is unlocked, the trolley can move along the slideway and make the second section chute leave the vibrating screen.
[0005] In one embodiment, the cross-sectional area of the upper port of the second section chute is larger than the cross-sectional area of the lower port of the first section chute.
[0006] In one embodiment, the vibrating screen feeding device further comprises: a rubber skirt for shielding provided at the connection between the first section chute and the second section chute.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0025] Figure 1 This is a schematic structural diagram of a vibrating screen feeding device according to an embodiment of the present invention. The vibrating screen feeding device includes a discharge device 1 for discharging slurry, a first chute 2 fixedly connected to the discharge device 1, a slide, a trolley located on the slide, a position locking device, and a second chute 3 fixed to the trolley. ( Figure 1 (The slide, trolley, and position locking device are not shown)
[0026] The first section chute 2 has a rectangular upper port and a lower port. The upper port is used to receive slurry from the ore discharge equipment 1, and the lower port is used to discharge the slurry.
[0027] The second chute 3 has a rectangular upper port and a lower port. The upper port of the second chute 3 is used to receive the slurry from the lower port of the first chute 2 , and the lower port of the second chute 3 is used to transport the slurry to the vibrating screen 4 .
[0028] The trolley can move along the slide, thereby driving the second section chute 3 fixed on the trolley to move. The position locking device is used to lock the trolley to a predetermined working position on the slide. When the trolley is locked to the predetermined working position, the upper port of the second section chute 3 is located below the lower port of the first section chute 2, and the lower port of the second section chute 3 is located above the vibrating screen 4, so that the slurry from the ore discharge equipment 1 can be smoothly transported to the vibrating screen 4, and finally transported through the conveyor belt 5. When the position locking device is unlocked, the trolley can move freely along the slide, so that the second section chute 3 can leave the vibrating screen 4, making it convenient for the staff to repair and replace the vibrating screen 4.
[0029] The position locking device is used to ensure that the trolley does not shake or shift due to the impact of the slurry on the second chute 3 during operation. The position locking device can be located on the trolley or on the slide, as long as it can securely lock the trolley to a predetermined position on the slide. In one embodiment, the position locking device includes a locking pin and a locking hole that cooperates with the locking pin. The locking pin is provided on one of the slide and the trolley, and the locking hole is provided on the other of the slide and the trolley.
[0030] The first chute section 2 can be secured to the ore discharge equipment 1 in various feasible ways, such as by welding or bolting. Regardless of the method used, the first chute section 2 must be securely and reliably mounted to prevent it from shaking or shifting due to the impact of the slurry. In one embodiment, an adjustable valve is provided near the upper port of the first chute section 2 to control the flow of the slurry.
[0031] The first section chute 2 can be fixed on the trolley in various possible ways. In one embodiment, a locking device can be provided to fix the second section chute 3 in a suitable position on the trolley.
[0032] In one embodiment, see Figure 2 The first chute 2 is arranged at an angle to the vertical (i.e., inclined), and the angle can be, for example, between 10 and 30 degrees. In one embodiment, the chute near the lower port of the second chute 3 has a certain slope. The slope can be set according to actual needs (such as the discharge volume of the ore discharge equipment 1 and the slurry characteristics), ensuring smooth flow of the slurry at a moderate flow rate, thereby reducing the impact on the screen of the vibrating screen 4.
[0033] The first and second chute sections 2 and 3 have rectangular cross-sections and rectangular ports, and are relatively wide. The wide lower port of the second chute section 3 allows the slurry to be evenly distributed across different parts of the vibrating screen, preventing excessive stress on any part of the screen, thereby improving screening efficiency and screen life.
[0034] In one embodiment, in order to further improve the stability and safety of the first section chute 2 and the second section chute 3, a supporting device can be provided to provide support for the first section chute 2 and the second section chute 3 to ensure that the first section chute 2 and the second section chute 3 will not shake or shift due to the impact of the slurry during operation.
[0035] In one embodiment, the cross-sectional area of the upper port of the second chute 3 is larger than the cross-sectional area of the lower port of the first chute 2 to ensure smooth entry of the slurry into the second chute 3 and prevent slurry splashing. In one embodiment, a rubber skirt can be installed at the junction of the first and second chute 2, 3 to further prevent slurry splashing and minimize leakage risks.
[0036] In one embodiment, wear-resistant linings 6 are provided inside the first section chute 2 and the second section chute 3 to increase the wear resistance of the chute. The material of the wear-resistant linings 6 can be a rare earth wear-resistant alloy. In this way, it can be ensured that the chute has sufficient wear resistance and strength to withstand the long-term impact of the slurry and reduce wear, thereby reducing the frequency of maintenance and replacement. In one embodiment, see Figure 2 and Figure 3 , the wear-resistant lining 6 can be fixed to the first section chute 2 and the second section chute 3 using bolts, and the wear-resistant lining 6 can be easily replaced when necessary.
