Description

A ternary smelting slag crushing and screening equipment Technical Field

[0001] This utility model relates to the field of ternary smelting slag processing technology, specifically to a ternary smelting slag crushing and screening device. Background Technology

[0002] Ternary smelting slag is an industrial waste generated during metal smelting. It is usually associated with smelting processes containing three main metallic elements (or their compounds) and is commonly found in polymetallic ore smelting (such as smelting of symbiotic minerals like copper, lead, and zinc) or specific alloy smelting processes. Ternary smelting slag can be reused after being processed by crushing and screening devices.

[0003] After being crushed, the ternary smelting slag falls directly into the vibrating screen for screening. The crushed slag directly impacts the screening plate inside the screen, which can easily cause impact damage to the screening plate. This not only requires frequent replacement of the screening plate, but also affects the continuity of the screening operation. Summary of the Invention

[0004] The purpose of this utility model is to provide a ternary smelting slag crushing and screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ternary smelting slag crushing and screening device, comprising a base, a plurality of support legs slidably connected to the base, a housing fixedly connected to the top of the support legs, springs fixedly connected to the bottom of the housing corresponding to the support legs, a plurality of screening plates fixedly connected inside the housing, a feed inlet fixedly connected to the top of the housing, a first motor fixedly installed together with the feed inlet and the housing, symmetrically arranged crushing rollers rotatably connected inside the feed inlet, gears fixedly connected to the output ends of the crushing rollers, a plurality of discharge outlets fixedly connected to the back wall of the housing, a door panel provided on the front wall of the housing, and a vibration motor fixedly installed on the side wall of the housing;

[0006] The housing is equipped with a pressure-reducing mechanism, which includes a second motor and two sliding grooves. Guide blocks are slidably connected inside each sliding groove. A striking plate is fixedly connected between the guide blocks. A pressure-bearing seat is fixedly connected to the striking plate. A pressure-bearing groove is opened on the pressure-bearing seat. A connecting plate is fixedly connected to the output end of the second motor. A pressing rod is fixedly connected to the bottom end of the connecting plate.

[0007] Preferably, the bottom ends of the springs are all fixedly connected to the top end of the base, the output end of the first motor is fixedly connected to the output end of one of the crushing rollers, and the gears are meshed with each other.

[0008] Preferably, the second motor is fixedly installed at the middle position of the top of the housing, and the sliding grooves are symmetrically opened inside the housing near the top position.

[0009] Preferably, the striking plate is located at the top of the inside of the housing, corresponding to the feed inlet.

[0010] Preferably, the bottom end of the extrusion rod has a movable through-pressure groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when the screening machine is in operation, the pressure reducing mechanism can drive the push plate to move back and forth continuously. By pushing and hitting the smelting slag falling from the feed port, the vertical impact force can be greatly reduced, and the smelting slag can be prevented from directly hitting the screening plate. This effectively delays the wear of the screening plate and extends its service life. It not only extends the replacement cycle, but also reduces the overall operating cost of the screening machine.

[0017] 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.

[0018] Please refer to Figures 1-4. This utility model provides the following technical solutions:

[0019] Example 1: A ternary smelting slag crushing and screening device includes a base 1, multiple support legs 2 slidably connected to the base 1, a box 3 fixedly connected to the top of the support legs 2, springs 4 fixedly connected to the bottom of the box 3 at the positions corresponding to the support legs 2, multiple screening plates 5 fixedly connected inside the box 3, a feed inlet 6 fixedly connected to the top of the box 3, a first motor 7 fixedly installed together with the feed inlet 6 and the box 3, symmetrically arranged crushing rollers 8 rotatably connected inside the feed inlet 6, gears 9 fixedly connected to the output ends of the crushing rollers 8, multiple discharge ports 11 fixedly connected to the back wall of the box 3, a door panel 12 provided on the front wall of the box 3, a vibration motor 13 fixedly installed on the side wall of the box 3, the bottom ends of the springs 4 fixedly connected to the top of the base 1, the output end of the first motor 7 fixedly connected to the output end of one of the crushing rollers 8, and the gears 9 meshing with each other;

[0020] In use, the first motor 7 and the vibration motor 13 are started. The vibration motor 13 causes the housing 3 to vibrate up and down. When the housing 3 vibrates downward, it will drive the support leg 2 to move downward, and at the same time, the housing 3 will also compress the spring 4. When the housing 3 vibrates upward, it will drive the support leg 2 to move upward, and will also stretch the spring 4. The vibration of the housing 3 will drive the screening plate 5 to vibrate together. The first motor 7 will drive one of the crushing rollers 8 to rotate, the crushing roller 8 will drive the gear 9 to rotate, and the gear 9 will drive the other gear 9 to rotate. At this time, the two gears 9 and the two crushing rollers 8 rotate at the same time. Then, the ternary smelting slag is conveyed into the housing 3 through the feed port 6. The crushing roller 8 will crush the ternary smelting slag. The crushed slag will fall onto the top screening plate 5. The vibrating multiple screening plates 5 will screen the slag layer by layer and finally discharge it through the discharge port 11 to complete the crushing and screening work. When replacing the screening plate 5, simply open the door plate 12.

[0021] Example 2: The technical solution of this example that differs from that of Example 1 includes: a pressure reducing mechanism 10 is provided on the housing 3. The pressure reducing mechanism 10 includes a second motor 101 and two sliding grooves 102. Guide blocks 103 are slidably connected inside the sliding grooves 102. A striking plate 104 is fixedly connected between the guide blocks 103. A pressure bearing seat 105 is fixedly connected on the striking plate 104. A pressure bearing groove 106 is opened on the pressure bearing seat 105. A connecting plate 107 is fixedly connected to the output end of the second motor 101. A pressing rod 108 is fixedly connected to the bottom end of the connecting plate 107.

[0022] The second motor 101 is fixedly installed at the middle position of the top of the housing 3. The sliding groove 102 is symmetrically opened inside the housing 3 near the top position. The striking plate 104 is located inside the housing 3 at the top position corresponding to the feed port 6. The bottom end of the extrusion rod 108 is movable through the pressure bearing groove 106.

[0023] In use, the second motor 101 is started. When the debris falls into the box 3, the second motor 101 will drive the connecting plate 107 to rotate. The connecting plate 107 will drive the pressing rod 108 to rotate together. The pressing rod 108 will rotate with the connecting plate 107 towards the striking plate 104. When the pressing rod 108 rotates, it will squeeze the inner wall of the pressure groove 106. At this time, the pressure groove 106 will transmit the pressure to the pressure seat 105. The pressure seat 105 will then move in the direction of the rotation of the pressing rod 108. The movement of the pressure seat 105 will drive the striking plate 104 to move. The movement of the striking plate 104 will drive the two guide blocks 103 to slide in the sliding groove 10. In step 2, as the sliding and striking plate 104 moves, it strikes the falling slag, significantly reducing the force of the slag's vertical descent. At this point, the slag no longer exerts a strong impact on the screening plate 5, preventing damage to the top screening plate 5 and extending its service life. When the extrusion rod 108 rotates 90°, the continuously rotating rod will cause the pressure seat 105 to reset. The reset of the pressure seat 105 will also cause the striking plate 104 to reset. When the extrusion rod 108 returns to its initial position, it will again drive the striking plate 104 through the pressure seat 105 to strike the falling slag. This process of striking the slag is repeated.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
