Description

Technical Field

[0001] This utility model relates to the technical field of pretreatment equipment for laterite nickel ore, specifically a sieve plate for primary screening of laterite nickel ore that is easy to clean. Background Technology

[0002] Laterite nickel ore smelting technology is an industrial production technology that uses nickel oxide ore as raw material to extract nickel metal through hydrometallurgical and pyrometallurgical processes. It is mainly used in the manufacture of stainless steel and special steel. Among the pyrometallurgical processes, the blast furnace method has become a key technology due to its high output and the recyclability of slag.

[0003] When laterite nickel ore enters the production line, it needs to pass through a coarse screen to filter out large stones before being conveyed into the drying equipment. Currently, the screens used for initial screening of laterite nickel ore on the ground are mainly flat structures. Large stones that are filtered out rely on manual removal from the screens, which is time-consuming and labor-intensive. Furthermore, people standing on the screens are prone to getting stuck or tripping, increasing safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screen plate for primary screening of laterite nickel ore that is easy to clean, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a screen plate for primary screening of laterite nickel ore that is easy to clean, including a base, a screening support is provided on the top of the base, a slow motor is installed on the outside of the screening support, the output shaft of the slow motor is connected to a cleaning rod, and the cleaning rod is movably installed on the screening support, and the screening support is provided with several slots for screening, and a rocker arm is connected to the slot through a torsion spring shaft.

[0006] Optionally, the cleaning rods rotate clockwise at a constant speed under the drive of a slow-speed motor, and the bottom end of the cleaning rods can pass through the screening slots on the screening bracket, with the position of the cleaning rods corresponding one-to-one with the slots on the screening bracket.

[0007] Optionally, the rocker is installed inside the slot on the sieve support, and the rocker is tilted downward in its natural state. When the cleaning rod leaves the slot on the sieve support, the rocker can be lifted by the bottom end of the cleaning rod.

[0008] Optionally, the two ends of the bottom of the screening bracket are connected to the base by springs, and several rollers that can roll freely are installed at the position where the bottom surface of the screening bracket contacts the base. The rollers bear the weight of the entire screening bracket.

[0009] Optionally, several sleeves are symmetrically connected to the inner side of the base. The sleeves are fitted onto the outside of the connecting springs on the sieve support and the base, and the length of the sleeves is shorter than the length of the spring in its natural state.

[0010] Optionally, a vibrating block is connected to the outer side of the base, and a hemispherical object is connected to the vibrating block near the inner side of the base.

[0011] Optionally, a turntable is movably mounted on the outer side of the screening support via a rotating shaft. The central shaft of the turntable is connected to the central shaft of the cleaning rod via a transmission mechanism. When the cleaning rod rotates, it drives the turntable to rotate. A protrusion is connected to the outer side of the turntable. The outer side of the protrusion has an arc-shaped structure. The top part of the protrusion coincides with the hemispherical part on the vibrating block.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1 This utility model provides a technical solution: the sieve plate for primary screening of laterite nickel ore includes a base 1, with corresponding fixing components on the outside of the base 1. The base 1 is fixedly installed on the ground, and a pit is located below it. A corresponding conveyor belt is installed at the bottom of the pit so that the screened laterite nickel ore can be transported to the drying area. A screening support 2 is installed above the base 1, and a cleaning rod 3 is installed on the screening support 2. The cleaning rod 3 is movably connected by a rotating shaft. A slow-speed motor 7 is installed on the outside of the screening support 2. The output shaft of the slow-speed motor 7 is connected to the cleaning rod 3. The slow-speed motor 7 is a slow-speed motor that can drive the cleaning rod 3 to rotate at a uniform and slow speed. A strip filter groove is opened on the screening support 2 to achieve primary screening of laterite nickel ore, so that large stones and other impurities in the raw material can be screened out.

[0019] Please see Figure 2 The cleaning rods 3 are evenly distributed according to the positions of the filter grooves on the sieve support 2. When the cleaning rods 3 rotate, their bottom ends can pass through the filter grooves on the sieve support 2, thereby pushing the stones and other impurities filtered down on the sieve support 2 to the outside of the sieve support 2. (See reference...) Figure 3 A rocker arm 4 is installed at the left end of the filter tank on the sieve support 2, and the cleaning rod 3 moves in the following direction. Figure 3 In the clockwise direction, the rocker plate 4 is connected by a torsion spring shaft. In its natural state, the rocker plate 4 tilts downward. When the cleaning rod 3 rotates, it pushes the stones and other impurities on the screening bracket 2 toward the rocker plate 4. When the cleaning rod 3 contacts the rocker plate 4, the rocker plate 4 is deflected upward by force, which promotes the discharge of stones and other impurities. When the cleaning rod 3 leaves the rocker plate 4, the rocker plate 4 returns to its original position. Through the cooperation of the cleaning rod 3 and the rocker plate 4, the automatic cleaning function of the screen plate can be realized, eliminating the need for manual cleaning of stones and other screening impurities. This saves manpower and avoids the need to interrupt the screening operation during manual operation. At the same time, it can also improve the screening efficiency of laterite nickel ore, thereby improving production efficiency.

[0020] Please see Figure 5 Several springs are installed at both ends of the bottom of the screening bracket 2. The outer ends of the springs are connected to the base 1. A turntable 5 is installed on the side of the screening bracket 2 via a rotating shaft. The central shaft of the turntable 5 is connected to the central shaft of the cleaning rod 3 via a transmission device. When the cleaning rod 3 is working, the turntable 5 also rotates. A protrusion 51 is connected to the outer side of the turntable 5. (See reference...) Figure 4A vibrating block 6 is connected to the outer side of the base 1. The vibrating block 6 is also located on the outer side of the turntable 5. The end of the vibrating block 6 facing the turntable 5 has a hemispherical protrusion. The outer end of the protrusion 51 is also a hemispherical structure, and the protrusion of the outer end of the protrusion 51 coincides with that of the vibrating block 6. When the turntable 5 rotates, the interaction force between the protrusion 51 and the vibrating block 6 causes the screening support 2 to move on the base 1. At the same time, through the cooperation of the spring connected to the side of the screening support 2, the reciprocating vibration of the screening support 2 can be realized, thereby promoting the working efficiency of the screen plate in screening laterite nickel ore. The bottom surface of the screening support 2 in contact with the base 1 The screen plate is equipped with a freely rolling roller 21, which greatly reduces the friction between the base 1 and the sieve support 2. The part of the bottom of the sieve support 2 that contacts the base 1 covers the base 1. The roller 21 is installed on the bottom of the sieve support 2, which greatly reduces the problem of soil clods getting stuck between the base 1 and the sieve support 2. Furthermore, a sleeve 101 is connected to the spring connecting the base 1 and the sieve support 2. The length of the sleeve 101 is shorter than the length of the spring in its natural state, which can protect the exposed spring and prevent the spring from getting stuck, thus ensuring the normal use of the screen plate.

[0021] In summary, this easy-to-clean sieve plate for primary screening of laterite nickel ore is used by fixing it in the primary screening area of ​​the laterite nickel ore. Its bottom is a recessed pit with a conveyor belt installed at the bottom. After the slow-speed motor 7 is connected to the power supply and put into use, the slow-speed motor 7 starts to rotate and drives the cleaning rod 3 to rotate slowly. The laterite nickel ore is poured onto the screen support 2. The filtered material passes through the screen support 2 and falls onto the conveyor belt, where it is transported to the drying device. Stones and other impurities remain on the screen support 2. The cleaning rod 3, driven by the slow-speed motor 7, moves along... Figure 1 The clockwise rotation shown causes stones and other impurities remaining on the screening support 2 to be moved to the position of the rocker plate 4 under the action of the cleaning rod 3. The bottom end of the rocker plate 4 is deflected by the pressure of the cleaning rod 3, and the stones and other impurities are discharged. When the cleaning rod 3 rotates to the state of leaving the rocker plate 4, the rocker plate 4 returns to its original position. The cleaning rod 3 rotates slowly under the drive of the slow motor 7 and makes the rocker plate 4 deflect periodically, so as to discharge stones and other impurities. At the same time as the cleaning rod 3 rotates, the turntable 5 also rotates at a uniform speed under the action of the transmission device, so that the protrusion 51 can periodically pass through the vibrating block 6 and generate an interaction force with the vibrating block 6. The screening support 2 is deflected by the pressure from the vibrating block 6, so as to achieve the effect of reciprocating translation of the screening support 2 and accelerate the screening of laterite nickel ore.
