Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral separation, in particular to a multi-layer high-frequency screen for mineral separation. Background Art
[0002] When selecting minerals in the mining industry, high-frequency vibrating screens are required to screen medium and fine particles. With the development of technology, the vibration frequency of vibrating screens used in mines is getting higher and higher, thereby improving the screening quality.
[0003] The multi-layer high-frequency vibrating screens currently used in the market all directly introduce the raw materials into the upper end of the vibrating screen, and complete the multi-layer screening during the vibration. However, the introduction is directly introduced through a conveyor belt or a conveying pipeline, and the amount of introduction cannot be effectively controlled. Raw materials often accumulate, resulting in a decrease in screening efficiency and quality. Therefore, there is room for improvement. Utility Model Content
[0004] The utility model provides a multi-layer high-frequency screen for mineral separation and selection to solve the problems raised in the background technology.
[0005] In order to solve the above problems, the utility model provides a multi-layer high-frequency screen for mineral selection, including a high-frequency screen body, a feed hopper is installed on the upper end of the high-frequency screen body, a discharge port is arranged at the bottom of the feed hopper, and two limit rails are symmetrically arranged at both ends of the discharge port, a level sensor is arranged on the upper part of the feed hopper, a blocking plate for blocking the discharge port is slidably connected in the limit rail, a discharge groove matching the discharge port is arranged at the front end of the blocking plate, a connecting plate is fixedly installed on the rear side of the blocking plate, a telescopic cylinder is connected to the rear end of the connecting plate, the telescopic cylinder is installed in a fixed frame, two limit blocks with guide holes are symmetrically arranged on both sides of the telescopic cylinder in the fixed frame, and the fixed frame is arranged on the rear side of the high-frequency screen body.
[0006] Preferably, a discharge hopper is fixedly installed at the lower part of the discharge trough and is located above the screen in the high-frequency screen body, and the discharge hopper is located between two symmetrical limit rails.
[0007] Preferably, two guide rods are symmetrically fixed on the rear side of the blocking plate, and the two guide rods are located on both sides of the telescopic cylinder, and the two guide rods are slidably sleeved in the limit block through the guide holes.
[0008] Preferably: the side surface where the connecting plate and the blocking plate are connected is in conflict with the rear side of the limit rail, and both sides of the front end of the blocking plate are provided with limit rods in conflict with the front sides of the two limit rails. The beneficial effects of adopting the above technical solution are:
[0009] 1. When the height of the ore in the feed hopper reaches the upper material level sensor, the telescopic cylinder drives the plugging plate to move and retract, so that the discharge trough is connected with the discharge port of the feed hopper, and the ore in the feed hopper is discharged. When the ore in the feed hopper is below the lower material level sensor during discharge, the telescopic cylinder drives the plugging plate to move and block the discharge port, so that the feed hopper can temporarily store material, which is convenient for the high-frequency screen body to vibrate and screen the received ore, and then repeat the above process. Through quantitative intermittent feeding, it can be ensured that the ore in the high-frequency screen body is not easy to cause accumulation, thereby improving the screening efficiency.
[0010] 2. The setting of the discharge hopper at the lower end of the discharge trough can evenly guide the mineral material into the high-frequency screen body, so that the discharge is uniform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Through the above technical scheme, the mineral materials that need to be multi-stage screened are fed into the feed hopper 2 through a conveyor belt or a conveying pipeline. When the mineral materials reach the position of the upper material level sensor 3 in the feed hopper 2, the upper material level sensor 3 feedbacks information, and then controls the telescopic cylinder 6 to drive it to retract, and drives the blocking plate 5 to slide along the limit rail 22 through the connecting plate 52, so that the discharge groove 51 at the front end of the blocking plate 5 is docked with the discharge port 21 of the feed hopper 2, and the mineral materials in the feed hopper 2 are quickly discharged into the high-frequency screen body 1 for vibration screening. When the position of the mineral materials in the feed hopper 2 is lower than the lower material level sensor 4, the lower material level sensor 4 feedbacks information and then controls the telescopic cylinder 6 to drive it to expand and drive the blocking plate 5 slides along the limit rail 22, and the discharge port 21 is blocked by the rear end of the blocking plate 5. The above process is repeated to intermittently feed the high-frequency screen body 1, so that it is not easy to cause the accumulation of mineral materials in the high-frequency screen body 1, and the received mineral materials can be quickly sorted. At the same time, the temporary storage of the feed hopper 2 does not affect the transportation of the mineral materials, which effectively improves the sorting efficiency. The setting of the limit rail 22 can make the blocking plate 5 stably connected to the discharge port 21 of the feed hopper 2, thereby ensuring the stability of discharging and blocking. The upper material level sensor 3 and the lower material level sensor 4 are used to detect the position of the mineral materials in the feed hopper 2, and the fixing frame 7 is used to improve the stability of the equipment installation connection.
[0020] Preferably, a discharge hopper 53 located above the screen in the high-frequency screen body 1 is fixedly installed at the lower part of the discharge trough 51 , and the discharge hopper 53 is located between two symmetrical limit rails 22 .
[0021] Through the above technical solution, the setting of the discharge hopper 53 does not affect the movement of the sealing plate 5 in the limit rail 22, and the discharge trough 51 receives the mineral materials in the discharge port 21 for guidance, so that the mineral materials are not easily scattered, and then the mineral materials are evenly introduced into the high-frequency screen body 1, thereby improving the screening efficiency.
[0022] Preferably, two guide rods 82 are symmetrically fixed on the rear side of the connecting plate 52 , and the two guide rods 82 are located on both sides of the telescopic cylinder 6 , and the two guide rods 82 are slidably sleeved in the limit block 8 through the guide holes 81 .
[0023] Through the above technical scheme, the movement of the blocking plate 5 can be further limited by the two guide rods 82 in cooperation with the limit block 8, thereby further improving the stability of the connection between the blocking plate 5 and the feed hopper 2, and further improving the stability of the blocking plate 5 in blocking or opening and closing the discharge port 21 in the feed hopper 2.
[0024] Preferably, the side surface of the connecting plate 52 connected to the blocking plate abuts against the rear side of the limiting rail 22 , and two limiting rods 54 abutting against the front side of the limiting rail 22 are provided on both sides of the front end of the blocking plate 5 .
[0025] Through the above technical solution, the connection plate 52 and the limiting rod 54 are arranged to limit the movement of the blocking plate 5 , thereby preventing the blocking plate 5 from falling off from the limiting rail 22 .
